Hereinafter, an embodiment of an oxygen replenishing device for a seabed water area according to the present invention will be described with reference to FIGS. 1 to 4.
In FIG. 1, 1 is a land river, for example, a river passing through an urban area, and the river water flows into the inland sea 2. In the inland sea 2, the upper layer 2 a is warm in summer, while the lower layer 2 b descending from the upper layer 2 a is cold water in summer. 3 is the bottom of the sea, and its depth is about 20m here. An oxygen deficient state occurs in the seabed water area 4 when the seabed 3 has a depth of 15 to 20 m.

On the other hand, the oxygen supply device is made of stainless steel, aluminum alloy, resin, or the like. 10 is an upright floating installation type pump, and this pump 10 has a vertically cylindrical (cylindrical) cylinder 11 having a diameter of about 30 to 50 cm and a lower end introduction port through which seawater in the seabed water area 4 can be introduced ( A lower pipe 13 provided with a means 12 that can be introduced).
The cylinder 11 includes a pump drive device 16 that moves up and down in synchronization with the wave generated by the surface wave 15. The pump driving device 16 has a float type wave receiving material (actuator) 17 which is an essential part of a wave receiving mechanism that moves up and down in synchronization with the wave of the surface wave 15 with an appropriate weight, and an upper portion of the cylinder 11. And a support arm 18 projecting from the head. A piston 20 is provided in the cylinder 11 so as to be movable up and down, and an upper through hole 21 is formed on an upper surface portion thereof, and an upper valve 22 that can be opened and closed so as to open the upper through hole 21 upward. Is provided. On the upper side of the upper valve 22, an upper stay 23 composed of a plurality of thin rods is erected so that the upper valve 22 is regulated only in the vertical movement, and an upper plate 24 is provided on the upper end thereof.

A rod 26 projecting from the upper plate 24 onto the cylinder 11 is erected, and this rod 26 is rotatably connected to the base of an interlocking lever (transmission conversion mechanism) 27. An intermediate point of the interlocking lever 27 is rotatably supported on the upper end of the support arm 18 via a fulcrum shaft 19 which is a horizontal axis. The axial direction of the fulcrum shaft 19 is perpendicular to the traveling direction of the surface wave 15, or in other words, when it is parallel to the wave ridge line perpendicular to the traveling direction of the surface wave 15, the pump drive device 16 can make a smooth interlocking movement with less drowning and resistance. However, the vertical movement of the wave-receiving material 17 can be obtained even if the wave traveling direction and the direction of the fulcrum shaft 19 are not perpendicular. For example, even if the axial direction of the fulcrum shaft 19 and the traveling direction of the surface wave 15 are the same direction or have a directional crossing relationship, the wave-receiving material 17 can move up and down.
A partition plate 28 and a vertically movable spring plate 29 are provided in the upper portion of the cylinder 11, and a spring 30 is provided above and below the spring plate 29 to smooth the movement of the rod 26 up and down. . A pre-water storage space A is formed in the lower part of the cylinder 11, and a lower valve 32 is provided at the lower end of the main body 11 so as to open upward and have a lower through hole 31. The upper and lower valves 22 and 32 are formed in a spherical shape, but may be formed in a plate shape that can be easily operated with a resin or the like. 33 is a lower stay, and 34 is an upper net.

Reference numeral 36 denotes an inner water outlet, which is opened in the peripheral portion of the pressurized delivery space B corresponding to the space between the partition plate 28 of the cylinder 11 and the piston 20, and an inner water outlet pipe 37 is connected to the outlet 36. It is provided in a form protruding in the horizontal direction. The direction is the upper layer 2a. The pipe 37 may be provided in the radial direction as shown in the right column of FIG.
Further, 40 is an upper arm whose length can be adjusted. An upper float (floating holding means) 41 is provided at the tip of the arm 40, and together with the lower float (floating holding means) 42, the cylinder 11, the lower pipe 13, and the up and down swing. The main part of the device such as the dynamic pump drive device 16 is erected in a vertical cylinder shape so that a constant height portion at the top of the main body 11 is on the water surface.

45 is a guide holding means for moving the pumping pump 10 up and down according to the tides while maintaining a vertical state at a fixed position in the inland sea 2 so that the upper part of the cylinder 11 is always on the water surface.
This guide holding means 45 has a fixed pipe 47 with a flange 46, and this pipe 47 is provided with through holes 48 for introducing seawater in the seabed water area 4, and level adjusting tools are provided at three or more locations on the flange 46. By mounting 49, the fixed pipe 47 can be defined vertically. A plurality of anchoring anchors 50 whose lengths can be adjusted are stretched between the fixed pipe 47 and the seabed 3 so as to reliably define the vertical state together with the level adjuster 49. The fixed pipe 47 is provided with a plurality of guide rollers 51 so that the lower pipe 13 can be controlled to a height corresponding to the tidal range.

  In the state where the surface wave 15 is generated in the inland sea 2 and the wave receiving moving material 17 is lowered as shown in FIG. 2 by the mountain of the wave, the upper and lower two valves 22 and 32 are in a state where the through holes 21 and 31 are closed. . As shown in FIG. 3, when the wave-receiving material 17 reaches and rises above the surface wave 15, the piston 20 is pushed down via the rod 26, and at the same time, the lower valve 32 is closed and the upper valve is closed. 22 is opened, and the cold seawater that has been brought into the lower space (prewater storage space A) in the previous stage is brought into the upper space of the cylinder 11 (pressurized delivery space B).

Next, when the wave-receiving material 17 falls into the wave valley as shown in FIG. 4 by tuning to the surface wave 15, the rod 26 rises and lifts the piston 20, whereby the upper valve 22 is closed and the pressure is sent out. The water in the space B is discharged as cold pressurized water to the upper layer 2a through the inner water outlet and the pipes 36 and 37.
When the cold seawater is discharged to the upper layer 2a, the seawater has a specific gravity greater than that of the warm seawater of the upper layer 2a, so that the seawater descends with the warm seawater. At that time, the warm seawater contains a lot of oxygen and descends along with them to bring oxygen to the seabed water area 4.

On the other hand, the lower valve 32 is opened by lifting the piston 20 to introduce seawater in the lower pipe 13. The cold seawater in the seabed water area 4 is repeatedly introduced into the lower pipe 13 each time.
When the piston 20 is lifted to the state shown in FIG. 2, the lower valve 32 that has been opened is closed and the discharge of seawater is temporarily stopped. Next, the wave-receiving material 17 is moved up and down by the wave of the surface wave 15 as shown in FIGS. 3 and 4, so that cold seawater is repeatedly pumped up and released.

  As shown in FIGS. 3 and 4, a shut valve 38 is provided in the inner water outlet 36 or the pipe 37, and the piston 20 is closed while being lowered (FIG. 3) and opened while being raised (FIG. 4). For example, as shown in FIG. 3, there is no loss in which the water in the pipe 37 is reversed or mixed due to the pulling-down force when the piston 20 is lowered, so that the pumping operation is less wasteful and efficient. Will be able to drive smoothly. This aspect may also be adopted in other embodiments.

  As shown on the left side of FIG. 2, the wave receiving member 17 is moved up and down by accurately grasping the stable movement of the rising and falling water surface without being disturbed by the wave-dissipating member 92 surrounding the outer periphery thereof. It can be configured to be interlocked. The wave eliminating member 92 is a cylinder or a square cylinder having an open top and bottom, and is supported by upper and lower mounting arms 93 extending from the cylinder 11 side. As shown in the upper column of the left side view of FIG. 2, the wave eliminating member 92 is configured to be vertically constricted and conical, so that the interlocking lever 27 operates reliably with a large push-up force and amount acting. May be. The tube of the wave eliminating member 92 may be made of a porous member such as a net shape or a punching shape.

The upper valve 22 provided in the piston 20 is formed of a rectangular plate or a circular plate that is supported by a hinge 22a so as to be opened and closed as shown in the lower left side of FIG. On the other hand, it can be configured to be openable and closable so as to limit the angle so that it can be returned to the original position by the opening stopper 26a when opened as shown in FIG.
On the other hand, the wave-receiving moving material 17 is formed as a sphere, but as shown by 17A on the left side of FIG. 3, it is formed of a vertical cylindrical hollow body, or a rectangular solid as shown by 17B below it. It can also be formed by a hollow body. In these cases, wave receiving members 95 and 96 that receive waves at the bottom side and give buoyancy to the wave receiving dynamics 17A and 17B to positively move up and down may be attached. In order to have the same function as the wave receiving members 95 and 96, as shown as a back wall 92a in the left side view of FIG. 2, the wave receiving member is not a cylindrical material but only a semi-cylindrical part or an elevation wall part. May be configured.
The wave-receiving material 17 is arranged in front of the surface wave 15 in the cylinder 11 so that the rod 26 can be moved up and down without difficulty. For example, the surface layer is located on the front side or the opposite side in FIG. It is free to arrange the wave-receiving dynamic material 17 based on the positional relationship such that the wave 15 is pushed, or to arrange the wave-receiving dynamic material 17 based on the positional relationship where the surface wave 15 is pushed from the right side of FIG. And in any case, the wave receiving dynamic material 17 can move up and down. However, for smooth operation of the wave-receiving material 17, it is preferable to place and maintain the wave-receiving material 17 in front of the surface wave 15 as shown in FIG. In order to maintain this arrangement, for example, the guide roller 51 is fixed on the seabed 3 so as to be front and rear with respect to the wave (left and right in FIG. 2), and the lower pipe 13 is front and rear with respect to the wave traveling direction (see FIG. By providing grooves so as to be positioned at the left and right (in FIG. 2), the grooves and the guide roller 51 are always in a relationship of moving up and down while fitting in the front and rear (left and right in FIG. 2) with respect to the wave traveling direction. A smooth up-and-down movement is made on the side where the waves 15 come closer. The same applies to the following embodiments.

FIG. 5 shows an embodiment in which seawater introduced into the fixed pipe 47 is taken in from a wide range by branch pipes 54 radiating from the fixed pipe 47. A plurality of inlets 55 are opened in the pipe 54 so that suction can be performed from a wide range.
FIG. 6 shows another embodiment of the guide holding means. In this embodiment, the base block 57, which is a heavy object, is provided with a cylinder jack 58 such as hydraulic pressure or hydraulic pressure so that the fixed pipe 59 is held vertically. 60 is a pipe.
FIG. 7 shows another embodiment of the guide holding means. This guide holding means is a screw type anchor pile 63 that can be driven into the seabed 3.

  8 to 10 show another embodiment of the guide holding means. The same components as those in FIG. 2 are denoted by the same reference numerals and are not described. The guide holding means includes a guide holding pipe 66 with a roller 65 for holding the cylinder 11 of the upright floating installation type pumping pump 10 from its outer periphery, and a twin-bottle type movable floating body that stably floats on the sea. 66 and a trolley 68 connected to a connecting arm 67 via a connecting arm 67. The trolley 68 includes a left and right trolley main body 68a and a connecting pedestal 68b that connects them, and the distance between the left and right trolley main bodies 68a is as wide as 30 to 50 m. On the other hand, the wave can be taken in between the carrier main bodies 68a. Further, the trolley 68 includes an engine 69, a screw 70, and a steering rudder 71, and is movable in the inland sea 2. These movements can be controlled by remote operation. While the trolley 68 is movable, it can be anchored by the anchoring means. 74 is an operation residence room. Since the pump 10 is levitated via a pontoon 68 which is a float, it is an upright floating installation type.

Note that the upper float (floating holding means) 41 is attached by using the inner water ejection pipe 37, and is also connected to the lower pipe 13 to introduce the seawater in the seabed water area 4 as a flexible tube 72 and an introduction network. 73 is provided.
As shown in the left column diagram of FIG. 8, the trolley main body 68a may be of a circumferential point arrangement type such as four points or six points so that waves can enter from four directions as much as possible.
If a shut valve 38 is provided in the internal water ejection pipe 37 as shown in FIG. 3 and FIG. 4 so as to open while the piston 20 is being lowered, for example, when the piston 20 is lowered. There is no loss in which the water in the pipe 37 is reversed or mixed due to the pulling-down force. Therefore, the pumping operation is less wasted and efficient operation can be performed.
Although the cylinder 11 is held so as to be movable up and down via the guide holding pipe 66 on the side of the carriage main body 68a, the cylinder 11 may move up and down arbitrarily according to the wave motion. As shown in the right column, the connecting arm 67 and the cylinder 11 may be directly coupled and supported without the guide holding pipe 66. The pumping operation becomes stable. In this case, the trolley 68 becomes the levitation holding means.

In the case of this embodiment, it is possible to pump up seawater while moving in the inland sea 2 and supply oxygen to the original seabed water area 4, so that oxygen can be supplied over a wide range.
In addition, as shown in FIG. 10, a bilge keel 75 may be provided on the trunk of the trolley 68 so as to make the trolley more stable. In this case, the tip of the bilge keel 75 may be provided with a round rod 76 that also serves as a balancer so as to be further stabilized, or as shown in the right column of FIG. In this case, if the net portion 77 is attached to the tip, stabilization can be achieved by its proper water flow / resistance function.

  FIG. 11 shows another embodiment. The same components as those in FIG. 2 are denoted by the same reference numerals and are not described. The guide holding means holds the cylinder 11 from its outer periphery and can guide the cylinder 11 up and down with a guide roller 80, and a crawler type travel that supports the pipe 81 so as to be vertical and can move the seabed 3 A traveling machine body 83 with wheels 82 is provided. This traveling machine body 83 is of a type that can be remotely operated underwater, and a flange 85 at the lower end of the guide holding pipe 81 is disposed on the machine body 83 via a spherical bearing joint 84, and between the machine body 83 and the flange 85. By connecting them with a connecting shaft 86 with a spring, the airframe 83 is always controlled vertically even when the airframe 83 is inclined due to the unevenness / inclination of the seabed 3. A pipe 88 of the guide holding pipe 81 is overhanged, and a lower float 90 is attached to the pipe 88 to bring the guide holding pipe 81 into a vertical posture. The pipe 88 also serves as a guide pipe for taking the seawater in the seabed water area 4 into the guide holding pipe 81.

If a shut valve 38 is provided in the internal water ejection pipe 37 as shown in FIG. 3 and FIG. 4 so as to open while the piston 20 is being lowered, for example, when the piston 20 is lowered. There is no loss in which the water in the pipe 37 is reversed or mixed due to the pulling-down force. Therefore, the pumping operation is less wasted and efficient operation can be performed.
In the case of this embodiment, it is possible to pump up seawater while moving the seabed 3 and supply oxygen to the original seabed water area 4, so that oxygen can be supplied over a wide range.

  12 to 14 show another embodiment. In the above-described embodiment, the pump driving device is configured to use the fact that the wave of the surface wave 15 moves up and down, and that the vertical motion is directly regarded as the vertical motion and is converted into the vertical motion of the piston 20. In the embodiment shown in FIG. 12 to FIG. 14, focusing on the fact that the wave generated by the surface wave travels in a certain direction and moves up and down, a wave receiving material (actuator) supported around the horizontal axis by the movement. ) Is effectively reciprocated to provide an oxygen replenishing device equipped with a pump drive device that can be efficiently linked to the piston movement.

  12 to 14, reference numeral 100 generates a wave that is a sine wave traveling in the right direction while moving up and down by a surface wave. In FIG. 13, 101 is the seabed, and the water depth is about 20 m here. An oxygen deficient state at the seabed 101 occurs in the seabed water region 102 when the water depth is 15 to 20 m. This oxygen supply device is installed in the environment shown in FIG. For example, river water passing through an urban area flows into the inland sea 103, and the inland sea 103 is warm in the upper layer 103a in summer and cold in the summer in the lower layer 103b.

  On the other hand, the oxygen supply device is made of stainless steel, aluminum alloy, resin, or the like. Reference numeral 105 denotes a guide holding means. The guide holding means 105 has a fixed pipe 107 with a flange 106, and this pipe 107 is provided with a through hole 108 which is a means for introducing cold seawater in the seabed water area 102. The fixed pipe 107 can be defined vertically by installing level adjusters 109 at three or more locations on the flange 106. A plurality of anchoring anchors 110 whose lengths can be adjusted are stretched between the fixed pipe 107 and the seabed 101 so that the vertical state of the fixed pipe 107 together with the level adjuster 109 is reliably defined. The fixed pipe 107 is provided with a plurality of guide rollers 111 so that the pumping pump 115 side can be controlled to a height corresponding to the tidal range. The guide holding means 105 is for moving the pumping pump 115 up and down according to tides while maintaining a vertical state at a certain position in the inland sea 103 so that the upper part of the cylinder 116 is always on the water surface.

The upright floating installation type pumping pump 115 is a lower part having a diameter of about 30 to 50 cm and having an upper lid 116 a and a vertically-oriented cylinder (cylindrical) cylinder 116 and a lower end inlet 117 capable of introducing seawater in the seabed water area 102. And a pipe 118. The upper lid 116a may be provided with an air vent hole to reduce the internal pressure.
Inside the cylinder 116 is provided a piston 120 having a transverse wall and a cylindrical wall and capable of moving up and down. The transverse wall of the piston 120 is provided with an upper valve 122 having a plurality of upper through holes 121 that can be opened and closed. When the piston 120 is pushed down as shown in FIG. 13 by the action of a back-and-forth oscillating pump driving device 130 described later, the upper valve 122 is opened, and the seawater in the prewater storage space A below the pressurized water supply space B is opened. To be guided to.

On the contrary, as shown in FIG. 14, when the piston 120 is lifted by the action of the pump driving device 130, the upper valve 122 rises while being closed horizontally. As a result, the lower valve 125 provided in the lower through-hole 124 opened in the lower portion of the cylinder 116 is opened so that the seawater in the lower pipe 118 is brought into the prewater storage space A, and the pressurized water supply space B The inner seawater is guided from the lower layer 103 b toward the seabed water region 102 through an inner water ejection pipe 126 attached to the cylinder 116. 127 is an internal water outlet, and if the shut valve 128 is provided in the outlet 127 so as to be opened while the piston 120 is being lowered, for example, a pulling force when the piston 120 is lowered is provided. As a result, there is no loss such that the water in the pipe 126 is reversed or mixed, so that the pumping operation is less wasteful and efficient operation can be performed.
In addition, the outer periphery of the cylinder 116 is provided as a floating holding means such as an upper float 41 and a lower float 42 as shown in FIG. 2, and the upper portion of the cylinder 116 is close to the water surface (average height of the surface wave 100). In addition, it is defined that the lower part of the cylinder is submerged in the sea.

On the other hand, the cylinder 116 includes a pump driving device 130 that is interlocked so as to synchronize with the progress of the wave by the surface wave 100 that travels so as to generate a sine wave at the peak portion a and the valley portion b.
The pump drive device 130 includes a horizontal fulcrum shaft 132 at the tip of a stay 131 provided with a pair of left and right extending on the wave traveling direction side of the upper end of the cylinder 116, and a net-like wave response mechanism around the fulcrum shaft 132. A wave-receiving moving material (actuator) 133 which is a main part of the first embodiment is attached in a vertical direction and a pair of left and right sides so as to swing back and forth between a front diagonally downward state and a rear diagonally downward state. The fulcrum shaft 132 is oriented perpendicular to the traveling direction of the wave. In other words, the fulcrum shaft 132 that is the central axis of rotation of the wave receiving dynamic material 133 is parallel to the wave ridge line L shown in FIG. 12, and this is because the pair of left and right wave receiving dynamic materials 133 and 133 operate synchronously. This is to make it easier.

  An interlocking link member 134 that similarly swings back and forth is projected on the upper side of the wave receiving dynamic member 133 about the axis, and a cam link 134 a is provided at the tip of the interlocking link member 134. On the other hand, a vertical guide rail 136 made up of a pair of channel steels is erected at the center of the upper lid 116a, and a roller 138 at the upper end of the rod 137 that rises from the center of the piston 120 through the upper lid 116a is perpendicular to the rail 136. It can be moved up and down. A horizontal shaft 139 is attached to the upper end of the vertical guide rail 136, and the upper link 141 attached to the horizontal shaft 139 includes a cam roller 142 at the tip. The middle of the upper link 141 and the roller 138 are connected by a lower link 143, and the roller 138 of the upper link 141 is movably engaged with the cam link 134a. The interlocking link 134, the upper link 141, the lower link 143, and the like constitute a transmission conversion mechanism.

The wave receiving moving material 133 is a net-like material, but it can also be a perforated plate, and as shown in the right column of FIG. 12, it may be a vertical beam type or a horizontal beam type porous material. In addition, the wave-receiving material 133 is one, but it may be composed of a plurality of parallel planes. In this case, the seawater can escape constantly by providing a gap before and after the plurality of waves. If this is done, the return operation to the front will be smooth, and the force in the X direction can be suitably obtained.
Further, the wave-receiving moving material 133 moves from the slightly upward state in FIG. 13 to the direction of arrow X (wave traveling direction) by the energy of the traveling high wave part a and moves slightly upward. The obtained flat plate-shaped resin including a hollow mold, a wooden board, an aluminum alloy or other metal board can be used.
Further, the wave-receiving dynamic material 133 is used as a float-made wave-receiving dynamic material 133 </ b> A by itself or attached to the operating material 133 so that the operation in the X direction is assisted by the action of buoyancy. Sometimes.

  FIG. 12 and FIG. 13 show a state in which the oxygen supply device is supported upright with the support of the seabed 101, and the pumping pump 115 which is the upper part of the oxygen pumping apparatus sinks the lower part and floats the upper part above the water surface. Yes. Since the wave-receiving moving material 133 corresponds to the position of the valley b of the surface wave 100 first, it is in the state of a virtual line that has swung back by the action of the return spring (return means) 146 shown in FIG. Next, when the wave portion a of the surface wave 100 travels and hits the wave-receiving material 133 and pushes it in the X direction in FIG. 13, the pump driving device 130 changes from a virtual line state to a solid line state.

  That is, when the wave receiving dynamic member 133 is pushed later, the interlocking link member 134 is lowered forward, and the upper link 141 is pulled down via the cam link 134a, whereby the lower link 143 is also lowered to lower the rod 137. The piston 120 is lowered via the. When the piston 120 is lowered, the upper valve 122 is kept open while the lower valve 125 is closed, so that the seawater retained in the prewater retaining space A is brought into the pressurized water feeding space B through the upper through hole 121. It is. At this time, the shut valve 128 is closed due to the downward force of the piston 120, so that the seawater previously contained in the internal water ejection pipe 126 is reversed or further turbulent / resistance flow in the pressurized water supply space B. There is no risk of generating such.

When the wave receiving dynamic material 133 passes through the peak portion a, the wave receiving dynamic material 133 is now approached to the valley portion b. In this case, the wave receiving dynamic material 133 is actuated by a return spring 146 or a weight (not shown) as shown in FIG. Returned as shown by arrow Y in the absence of. At the same time as the wave-receiving material 133 is returned, the piston 120 is lifted with the upper valve 122 closed and the lower valve 125 opened, so that the seawater retained in the lower pipe 118 is pre-watered through the lower through hole 124. Oxygen replenishment is carried out by being brought into the inland sea 103 through the inland water outlet 127 where the seawater in the pressurized water supply space B is opened and brought into the reserved space A, and is guided toward the seabed as warm seawater that has obtained oxygen. Is called. After the operation in FIG. 14, the operation in FIGS. 12 and 13 is led.
In addition, as shown in FIG. 12, the wave to the wave receiving dynamic material 133 is strengthened by wave-dividing by the pumping pump 115, and the operation | movement is ensured.
In order for the surface wave 100 to act on the surface of the wave-receiving material 133 at a right angle, for example, the guide roller 111 is placed on the seabed 101 so that the guide roller 111 is in the front and back of the wave traveling direction in the fixed pipe 107 (left and right in FIG. 13). The lower pipe 118 is provided with grooves so as to be positioned in the front and rear (left and right in FIG. 13) with respect to the wave traveling direction. This can be achieved by moving up and down while fitting in front and rear (left and right in FIG. 13) with respect to the direction. The same applies to the following embodiments.

15 to 17 show another embodiment, which is a simplified pump drive device as compared to the embodiment of FIG.
The pump driving device 150 includes a horizontal fulcrum shaft 152 at the tip of a stay 151 provided extending in a pair of left and right on the wave traveling direction side of the upper end of the cylinder 116, and has a net-like wave response around the fulcrum shaft 152. A wave receiving moving material (actuator) 153, which is a main part of the mechanism, is attached vertically and paired to the left and right to swing back and forth between a front diagonally downward state and a rear diagonally downward state.

  An interlocking link member 154 that similarly swings back and forth is provided on the upper side of the wave receiving moving member 153 about the axis, and a cam link 154a is provided at the tip of the interlocking link member 154. On the other hand, a vertical guide rail 156 made up of a pair of channel steels is erected at the center of the upper lid 116a, and a roller 138 at the upper end of the rod 137 that rises from the center of the piston 120 through the upper lid 116a is perpendicular to the rail 156. It can be moved up and down. The roller 138 directly meshes with the cam link 134a so as to be movable. The interlocking link material 154, the cam link 154a, the roller 138, and the like constitute a transmission conversion mechanism.

  FIGS. 15 and 16 show a state in which the oxygen supply device is supported upright with the support of the seabed 101 and the pumping pump 115 which is the upper part of the oxygen supply apparatus is submerged in the lower part and the upper part is floated and held on the water surface. Yes. Since the wave receiving moving material 153 corresponds to the position of the trough b of the surface wave 100 first, it is in the state of an imaginary line that swings forward by the action of the return spring (return means) 146 shown in FIG. Next, when the crest a of the surface wave 100 travels and hits the wave receiving moving material 153 and pushes it in the X direction in FIG. 16, the pump driving device 150 changes from a virtual line state to a solid line state.

  That is, when the wave receiving dynamic member 153 is pushed later, the interlocking link member 134 is lowered forward and the roller 138 is pulled down via the cam link 134a, whereby the piston 120 is lowered via the rod 137. Like that. When the piston 120 is lowered, the upper valve 122 is kept open while the lower valve 125 is closed, so that the seawater retained in the prewater retaining space A is brought into the pressurized water feeding space B through the upper through hole 121. It is. At this time, the shut valve 128 is closed due to the downward force of the piston 120, so that the seawater previously contained in the internal water ejection pipe 126 is reversed or further turbulent / resistance flow in the pressurized water supply space B. There is no risk of generating such.

When the wave receiving dynamic material 153 passes through the peak portion a and passes through the peak portion a, the wave receiving dynamic material 153 now reaches the valley portion b. In this case, the wave receiving dynamic material 153 is actuated by a return spring 146 or a weight (not shown) as shown in FIG. Returned as shown by arrow Y in the absence of. At the same time as the wave-receiving material 153 is returned, the piston 120 is lifted with the upper valve 122 closed and the lower valve 125 opened, so that the seawater retained in the lower pipe 118 is pre-watered through the lower through hole 124. Oxygen replenishment is carried out by being brought into the inland sea 103 through the inland water outlet 127 where the seawater in the pressurized water supply space B is opened and brought into the reserved space A, and is guided toward the seabed as warm seawater that has obtained oxygen. Is called. After the operation of FIG. 17, the operation of FIG. 15 and FIG. 16 is led.
In addition, as shown in FIG. 15, the wave to the wave receiving dynamic material 153 becomes stronger when the pumping pump 115 divides the wave, and the operation is ensured.

  18 to 21 show another embodiment. This embodiment pays attention to the fact that the wave by the surface wave continuously proceeds in a certain direction and generates energy in that direction, and the wave-receiving motion supported so as to be rotatable around the horizontal axis by the movement. It is an object of the present invention to provide an oxygen replenishing device provided with a pump drive device that can effectively move the piston (movement) in an interlocking manner by effectively continuously rotating the material (actuator).

  In FIG. 18 to FIG. 21, reference numeral 200 denotes a wave that is a sine wave that travels in the right direction while alternately repeating a peak portion a and a valley portion b with a surface wave. In FIG. 19, 201 is the seabed, and the water depth is about 20 m here. An oxygen deficient state at the seabed 201 occurs in the seabed water area 202 when the water depth is 15 to 20 m. This oxygen supply device is installed in the environment shown in FIG. For example, river water passing through an urban area flows into the inland sea 203. The inland sea 203 is warm in the summer in its upper layer 203a, while it is cold in the summer in the lower layer 203b.

  On the other hand, the oxygen supply device is made of stainless steel, aluminum alloy, resin, or the like. 205 is a guide holding means, and this guide holding means 205 has a fixed pipe 207 with a flange 206, and this pipe 207 is provided with a through hole 208 that is a means for introducing cold seawater in the seabed water area 202. The fixed pipe 207 can be vertically defined by attaching level adjusters 209 at three or more locations on the flange 206. A plurality of anchoring anchors 210 that can be adjusted in length are stretched between the fixed pipe 207 and the seabed 201 so as to reliably define the vertical state of the fixed pipe 207 together with the level adjuster 209. The fixed pipe 207 is provided with a plurality of guide rollers 211 so that the pumping pump 215 side can be controlled to a height corresponding to the tidal range. The guide holding means 205 is for moving the pump 215 up and down according to tides while maintaining a vertical state at a fixed position in the inland sea 203 so that the upper part of the cylinder 216 is always on the water surface.

The upright floating installation type pump 215 has a diameter of about 30 to 50 cm and a lower end inlet (means that can be introduced) capable of introducing seawater in a vertically cylindrical (cylindrical) cylinder 216 and a seabed water area 202 with an upper lid 216a. ) And a lower pipe 218 provided with 217. The upper lid 216a may be provided with an air vent hole to reduce internal pressure.
Inside the cylinder 216, a vertically movable piston 220 having a transverse wall and a cylindrical wall is provided. The transverse wall of the piston 220 is provided with an upper valve 222 that has a plurality of upper through holes 221 that can be opened and closed. When the piston 220 is pushed down as shown in FIG. 19 by the action of the rotary motion type pump driving device 230 described later, the upper valve 222 is opened, and the seawater in the prewater storage space A below the pressurized water supply space B is opened. It has come to be guided.

On the contrary, as shown in FIG. 21, when the piston 220 is lifted by the action of the pump drive unit 230, the upper valve 222 rises while being closed horizontally. As a result, the lower valve 225 provided in the lower through hole 224 opened in the lower portion of the cylinder 216 is opened so that the seawater in the lower pipe 218 is brought into the pre-water storage space A and the pressurized water supply space B The inner seawater is guided from the lower layer 203 b toward the seabed water area 202 through the inner water ejection pipe 226 attached to the cylinder 216. 227 is an internal water jet, and if the shut valve 228 is provided in the outlet 227 so as to open while the piston 220 is lowered, for example, the pulling force when the piston 220 is lowered As a result, there is no loss that causes the water in the pipe 226 to be reversed or mixed, so that the pumping operation is less wasteful and efficient operation is possible.
In addition, a buoyancy generating means that is a float 229 is provided on the outer periphery of the cylinder 216 so that a part of the upper end of the cylinder 216 is near the water surface (average height of the surface wave 200) and the other lower part of the cylinder is submerged in the sea. It shall be prescribed in The buoyancy generating means 229 can be configured so that the buoyancy can be made large or small by using a system that can supply and discharge air by an operation from the sea.

On the other hand, the cylinder 216 includes a pump driving device 230 that interlocks with the progress of the wave by the surface wave 200 that travels so as to create a sine wave at the crest a and the trough b.
The pump drive device 230 is provided with a forward stay 233 at the end of a base stay 232 that extends in a pair of left and right on the wave traveling direction side of the upper end of the cylinder 216, and rotates between the ends of the stay 233. The impeller 235 is supported so as to be freely rotatable via a horizontal rotating shaft 236.
The rotary impeller 235 is a wave receiving mechanism, and a cylindrical drum 238 with side flanges 239 attached to both ends thereof has a longer axial length, and the other is shorter than that. In the outer periphery of each drum 238, a plurality of wave-receiving motion materials (actuators) 241... Made of a horizontally long plate are rotatably arranged via an outer peripheral fulcrum shaft 242. . When receiving the surface wave 200, the wave receiving dynamic member 241 rises from the center of rotation toward the radial direction by receiving the inner end against the peripheral stopper 243 on the outer periphery of the drum 238 and receives the wave force to rotate. Is done.

  Due to the buoyancy generated by the floating holding means (float) 229 and the drum 238, the rotational center 236 of the rotary impeller 235 is located about 10 to 20 cm below the surface wave 200 trough b, and the upper end around the top of the drum 238 is The height is substantially the same as that of the valley b, and the height when it comes around the outer periphery fulcrum shaft 242 is about the upper end height of the peak a. As a result, the wave receiving moving material 241 that has come to the upper part and becomes vertical, the wave force of the peak portion a acts from the front as shown by an arrow X in FIGS. 19 to 21 to generate a rotational force. . When the wave-receiving material 241 rotates backward, the wave-receiving moving material 241 moves away from the circumferential stopper 243 and falls backward while turning backward with reference to the outer peripheral fulcrum shaft 242, and the wave power of X is forward. Rotating force is generated by the front end being fastened to the circumferential stopper 243 while acting. When the trough b approaches the drum 238, it rises on the drum 238 as shown in FIG. 21, thereby pushing the corresponding wave-receiving material 241 in the X direction to convert it into a rotational force. As shown in FIG. 18, the width of the rotary impeller 235 is set to be 1.5 times to 2 times longer than the diameter of the cylinder 216 so that most of the energy of the surface wave 200 can be converted into rotational force. However, the impeller 235 having a width substantially the same as the diameter of the cylinder 216 may be used. The rotational axis center of the rotary impeller 235 is defined parallel to the wave ridge line L of the surface wave 200 as shown in FIG. This orientation is determined by defining the orientation of the lower pipe 218 with respect to the fixed pipe 207.

  The surface wave 200 acting within the width of the rotary impeller 235 is not as narrow as the full width of the surface wave 200 but the width of the impeller 235, and therefore has a small rotational energy and a limit. However, in order to increase the energy and obtain a strong rotational force, as shown in FIGS. 18 and 19, a wave spreading plate 245 having a front expanding shape may be provided in front of the rotary impeller 235. Good. Further, as shown in FIG. 19, a wave height control plate 246 that is gradually lowered from the front end to the rear so that the front end is higher than the peak portion a and the rear end is at the middle height of the peak portion a is attached to the rotary impeller 235. It is also possible to increase the rotational action of the rotary impeller 235 by increasing the energy by increasing the speed of proceeding in the X direction while pressing down the peak portion a in preparation for the front side. The wave height control plate 246 can be configured in combination with the wave gathering plate 245 or independently. The wave-receiving material 241 has a flat plate shape with no through holes. However, as shown in the upper right column of FIG. 20, the wave energy is softly converted into a rotational force by using a mesh or a perforated plate. May be.

  In this embodiment, the rotary impeller 235 is divided into left and right 235a and 235b, and a drive sprocket 248 is provided around the rotation shaft 236 corresponding thereto. A pair of left and right brackets 250 are erected on the cylinder 216, and an interlocking chain stretched by a tensioner 253 between the driven sprocket 252 provided around the crankshaft 251 and the drive sprocket 248 passed between the brackets 216. 254 is hooked so as to be interlocked. The crankshaft 251 and the rod 237 are connected by a connecting rod 255 that changes the rotational motion into a linear reciprocating motion. The drive sprocket 248, the interlocking chain 254, the driven sprocket 252, the crankshaft 251 and the connecting rod 255 constitute a transmission conversion mechanism.

  The oxygen replenishing device shown in FIGS. 18 to 20 is supported on the sea floor 201 and is held upright, and the guide holding means 205 causes the rotation axis 236 to be parallel to the wave ridge line L of the surface wave 200. If it is set offshore, it will always maintain that state. In order for the surface wave 200 to act on the surface of the wave-receiving material 241 parallel to the rotation axis 236 at a right angle, for example, the guide roller 211 is moved back and forth in the wave traveling direction of the fixed pipe 207 (left and right in FIG. 19). The fixed pipe 207 is fixed on the seabed 201 so as to form a groove, and the lower pipe 218 is provided with grooves so as to be positioned forward and backward (left and right in FIG. 19) with respect to the wave traveling direction. This can be achieved by moving 211 up and down while fitting in front and rear (left and right in FIG. 19) with respect to the wave traveling direction. The same applies to the following embodiment.

  When the surface wave 200 acts on the rotary impeller 235 and wave power in the X direction acts on the wave receiving moving material 241..., Rotational force is generated, and the vertical reciprocating motion of the rod 237 is continuously generated. FIG. 19 shows a state in which the rod 237 and the piston 220 are in the middle of lowering. Since the lower valve 225 is closed and the upper valve 222 is opened by this lowering, the rod 237 and the piston 220 are temporarily stored in the prewater storage space A. The water from the submarine water area 202 that has been provided is guided into the pressurized water supply space B above it. After that, when the rod 237 starts to rise, the lower valve 225 is opened and the upper valve 22 is closed as shown in FIG. 21, and the seawater in the pressurized water supply space B is opened. Is discharged as cold pressurized water into the upper layer 203a of the inland sea through the inner water jet pipe 226, and the discharge of this cold seawater has a specific gravity greater than that of the warm seawater of the upper layer 203a, so that it descends with warm seawater. At that time, the warm seawater contains a lot of oxygen and descends along with them to bring oxygen to the seabed water area 202.

  22 and 23 show another embodiment. This embodiment has the same purpose as described above, and in particular, even if the oxygen replenishing device is installed in any direction around the vertical axis, any one of the rotary impellers 235 always works in the direction in which the surface wave 200 is pushed. It can be used freely, and the interlocking is always obtained reliably. That is, as shown in FIG. 23, the guide holding means 205 of the oxygen replenishing device is of a type that is fixed to the seabed 201, and the lower pipe 218 that can be moved up and down via the guide roller 211 is fixed to the fixed pipe 207. The specific rotary impeller 235 on the left side in the drawing is set so as to face the side where the surface wave 200 approaches. However, the lower pipe 218 may rotate with respect to the fixed pipe 207, and in order to deal with such a situation, a rotary impeller 260 similar to the rotary impeller 235 is provided on the other three surfaces of the pump 215. Then, even if the surface wave 200 acts on any of the rotating impellers 260, the acting force is transmitted to a specific rotating impeller 235 so that the piston 220 can be interlocked using the pump driving device 230. .

  The rotating impeller 260 is a rotating impeller 235 that is separated into two parts on the left and right for the convenience of arranging the driving sprocket 248 so as to be positioned in the same row as the driven sprocket 252 on the cylinder 216, and is rotated synchronously. It is of a type that does not separate. Reference numeral 261 denotes a stay extending from the cylinder 216 in all directions, and a main frame 262 having a rectangular frame shape is provided through an outer end thereof. The main frame 262 is provided with a right-angled front protrusion 263 provided at an outer corner of the main frame 262. A frame is formed, and the rotary impellers 235, 260,... Are rotated and supported via a stay 263 in front of a pair of left and right, and the rotary shafts are mutually flexible or a universal universal joint type shown in the lower right column of FIG. Are connected by universal joints 264. Reference numeral 265 denotes a bearing, and 266 denotes a receiving arm thereof. In the rotary impeller 260, 268 is a drum, 269 is a side flange, 270 is a wave receiving moving material, and 271 is a circumferential stopper.

  FIG. 24 and FIG. 25 show another embodiment of an upright floating installation type pumping-up pump type oxygen supply device equipped with a rotary impeller type pump drive device. In particular, the floating holding means is a floating body type. The levitation holding means 275 is a catamaran and movable type barge whose width between each other is about 20 to 40 m, and the barge body 276 of this barge is made up of the left and right sides of the hollow cylindrical metal body. A pair of three bridges 277 are connected between the left and right of the front, back and rear. A step board 278 is provided on the upper surface of the main body 276 and an auxiliary bridge 279 is provided at the rear (right side in FIG. 24). Will be passed. These bridges 277 and 279 may be simply configured with one or two wide transfer plates including the step plate 278. Moreover, although it is a twin-barrel type, it may be a single-barrel type or three or more double-barrel type. Although the main body 276 is a metal body for stabilization, it may be a wooden hull or a reinforced resin hull. Further, the hollow type main body 276 may be provided with high stability against waves by putting water (including seawater) into the lower part thereof and putting the upper part into air. In this case, the amount of water introduced may be made variable so that the height of the carriage main body 276 relative to the sea level can be adjusted.

  A connecting arm 281 is provided from the front and auxiliary bridges 277 and 279 so as to correspond to the front and rear, and the pumping pump 282 is fixed in an upright manner so as to be located below the bridge 277 at the middle position between them. Yes. The pump 282 includes a cylindrical cylinder 283 and a piston 285 that moves up and down by a rod 284 therein. An upper valve 286 is provided in the piston 285, and a lower valve 288 is provided in the lower through hole 287 of the cylinder 283 so as to be opened and closed. 290 is a lower pipe that leads to a through hole 287, and a lower flexible pipe 291 made of resin or rubber is connected to the lower part thereof, and an introduction net member 293 that is a spherical net filter medium is connected to the tip thereof. It is attached. 294 is an internal water ejection pipe, 295 is an internal water ejection port, and 296 is a shut valve that opens only outward.

  A pair of left and right receiving stays 300 is passed between the bottoms of the front and middle bridges 277, and the rotary impeller 301 is a horizontal axis of rotation between them so as to be concentric with the center of the carriage. It is rotatably supported via 302. The rotary impeller 301 may be adjustable in height so that the height relationship with the surface wave 305 can be adjusted. Reference numeral 303 denotes a hollow drum, and 304 is a wave receiving moving material that is a blade. Reference numeral 306 denotes a drive sprocket, and reference numeral 307 denotes a driven sprocket. An interlocking chain 309 is stretched between these via a tensioner 308. A bracket 310 is provided at the center of the intermediate bridge 277, through which the crankshaft 311 is passed, and between the crankshaft 311 and the rod 284 is connected by a connecting rod 312 to perform linear reciprocating motion on the rod 284. To give. A pump driving device 313 is configured from the rotary impeller 201 to the connecting rod 312.

Reference numeral 315 denotes a cabin which is installed on the rear bridge 277, and a ship maneuvering means 316 including steering is provided in the cabin 315, and an engine which is rotated around a vertical axis so that the direction of the hull can be controlled at the back portion. Equipped with a driven propulsion device 318. The engine drive type in this case can be a solar power generation drive type by installing a large board on board. Reference numeral 320 denotes a front anchor, and reference numeral 321 denotes a front traction chain. The front traction chain 321 is mounted on a front winch 322 installed on the front bridge 277 so as to be wound and fed out. 325 is a rear anchor, 326 is a rear traction chain, and a rear winch 327 installed on the auxiliary bridge 279 is equipped with the rear traction chain 326 so as to be wound and fed. Reference numeral 330 denotes a manual auxiliary winch, which is provided on the auxiliary bridge 279 for winding and feeding a lifting chain 331 whose tip is connected to the flexible pipe 291. The front traction chain 321 or the rear traction chain 326 is made of a pipe (or tube) with a through hole so that seawater can be taken in, and the communication pipe 333 is connected to the cylinder 283 via the central tube axis in the winch 322 as shown in FIG. The pipe 333 may be provided with a part corresponding to the lower valve 288 on the pipe 333 so as to replace the lower pipe 290 and the flexible pipe 291. The winches 322, 327, and 330 are manually driven or electrically driven.
Incidentally, reference numeral 335 denotes a wave guide plate which is attached via a front bridge 277, and its forward opening angle can be adjusted. The wave height control plate 246 shown in FIG. 19 may be provided to guide the surface wave 305 as a low wave around the rotary impeller 301. 336 is the seabed, 337 is the seabed water area, and 338 is the inland sea.

  In this case, the oxygen replenishing device, which is a trolley, drives the winches 322, 327, and 330 to raise the anchors 320 and 325 and the flexible pipe 291, and operates the propulsion device 318 through the boat maneuvering means 316 such as starting and steering. It can be started by moving the trolley from the berthing stoppage during normal operation to the intended work site where oxygen supply is required. In the field area where the aircraft arrives, advance the trolley so that the left bow side (the side with the rotary impeller 301) is perpendicular to the left offshore side (the side where the waves come in) as shown in FIGS. Then, the front winch 322 is operated to loosen the front traction chain 321 so that the front anchor 320 is lowered to the seabed 336. After that, the propulsion device 318 is driven to move the base boat in the same direction and move backward about 5 to 10 m. Next, the rear winch 327 is driven out and the rear anchor 325 is lowered to the seabed 336. Then, the chains 321 and 326 are kept in tension by the winding operation of the rear winch 327 and the front winch 322. By doing so, the trolley obtains a state of facing the wave at right angles to the wave as shown in FIGS. 24 and 25, so that the wave-receiving material 304 can receive the wave energy of the surface wave 305 most efficiently. Thereafter, the auxiliary winch 330 is operated to lower the flexible pipe 291 to the seabed 336. The drive sprocket 306 to the connecting rod 312 constitute a transmission conversion mechanism.

  As the surface wave 305 advances, the rotary impeller 301 is driven to rotate and the crankshaft 311 is rotated, so that the rod 284 moves up and down. FIG. 25 shows a state in which the rod 284 is being lowered. At this time, the piston 285 descends while the upper valve 286 is opened with the lower valve 288 closed, so that the pumped seawater in the prewater storage space A is added upward. It is brought into the pressure water supply space B. Thereafter, when the piston 285 moves up, the lower valve 288 opens and the cold seawater deficient in oxygen in the seabed water region 337 is replenished into the prewater storage space A through the flexible pipe 291, while in the pressurized water supply space B. The sea water is jetted as cold pressurized water to the upper layer 338a of the inner sea 338 through the inner water ejection pipe 294, and when the cold sea water is discharged to the upper layer 338a, the sea water has a higher specific gravity than the warm sea water of the upper layer 338a. Will descend. At that time, the warm sea water contains a lot of oxygen and descends with them to bring oxygen to the seabed water area 4.
