Description

  The present invention relates to an artificial reef that can be used by being installed, for example, on the seabed, and that allows roots including abalone and turban shells to be released to be collected and the roots grown after the growth is collected. .

  An example of a conventional artificial reef is shown in FIG. 9 (see, for example, Patent Document 1). In the artificial reef 1 shown in the figure, a plurality of thin plates 2 are arranged with a gap 5 therebetween in the vertical direction. The thin plates 2 are spaced from each other by spacers 3 and are fastened together by a connecting rod 4.

According to the artificial reef 1, the gap 5 between the thin plates 2 can be provided as a spawning place for fish. Since the gaps 5 between the thin plates 2 are covered with the upper and lower thin plates 2 and are difficult to see from the outside, they are suitable for spawning and breeding fish.

  However, in the conventional artificial reef 1 shown in FIG. 9, for example, a root resource (not shown) including abalone and turban shell is discharged to the artificial reef 1, and a root such as abalone is released on the surface of each thin plate 2. Considering the use of growing resources and collecting roots grown after the growth, when collecting abalone grown and grown on each thin plate 2, the gap 5 between the thin plates 2 There is a problem that it takes time and effort to work.

  Therefore, if the gaps 5 are made larger in order to make it easier to put their hands into the gaps 5, the bulk of the artificial reef 1 is increased correspondingly, and the cost for installation and the like increases. In addition, it is conceivable that the depth dimension of each thin plate 2 is shortened so that the hand can easily reach the back of the thin plate 2. However, if the area of the thin plate 2 is to be a predetermined size, the width of each thin plate 2 is reduced. The dimensions need to be long. Thus, if there is a restriction on the shape of each thin plate 2, the artificial reef 1 may not be installed at a desired installation location.

  Then, if each nut 6 shown in FIG. 9 is removed from the connecting rod 4 and the plurality of thin plates 2 are separated, it is easy to collect abalone and the like that grow on the surface of each thin plate 2. Every time it is done, disassembling and assembling the artificial reef 1 has the problem that it takes time and effort.

  The present invention has been made in order to solve the above-described problems, and can easily collect abalone and other root resources such as abalone that have grown on the growing plate, and can provide a desired one according to the installation location. The object is to provide an artificial reef that can be formed into a shape.

  An artificial reef according to the present invention is an artificial reef capable of causing roots including abalone and turban shells to grow, and collecting the roots resources grown after the growth. It is characterized by comprising a growth plate that is detachably attached to the base by engagement of the concave portion and the convex portion, and on which the root resource is deposited.

  According to the artificial reef according to the present invention, for example, the abalone grown on the surface of the artificial reef set on the seabed can be caused to grow on the surface of the artificial reef. And so on. Then, when collecting the root resources such as abalone grown from the epithelial plate, the epiphytic plate may be removed from the base body by moving it in a direction in which the concave portion and the convex portion are disengaged. As a result, it is possible to easily extract the soot resource from the removed epiphysis plate. Moreover, it can also be easily attached to a base | substrate by moving an epidemic plate to the direction which a recessed part and a convex part engage.

  In the artificial reef according to the present invention, the plurality of epiphytic plates are arranged in multiple stages in the vertical direction in a substantially horizontal or inclined state, and each edge portion on both sides of the epiphytic plate is attached to the base body. It is good to be held by a plurality of grooves. If it does in this way, by making both the edge parts of an epidemic plate engage with or remove from a groove part provided in a base, an epidemic plate can be easily attached or detached to a base. And, because it has a configuration in which the growth plates are arranged in multiple stages in the vertical direction, the installation area of this artificial reef can be reduced, and the worker can discharge the root resources to make them grow on each growth plate. Or, when the root resource is collected from each growth plate, the moving distance for the work can be shortened. In addition, if the growth plate is arranged substantially horizontally, the root resources can be easily grown on the growth plate, and by placing the growth plate in an inclined manner, earth and sand etc. are placed on the growth plate. It can be made difficult to collect.

  Further, in the artificial reef according to the present invention, a locking device for locking a plurality of the growing plates attached to the base body to the base body is provided, and the locking device is provided for each of the landing plates. And each of the locking holes provided in the base, and a rod-shaped locking member that is inserted through the locking holes and locks each of the growth plates to the base. Good. In this way, when locking a plurality of deposition plates attached to the base with respect to the base, the locking members are inserted through the respective locking holes provided in the respective plates and the base. That's fine. By locking each of the growth plates to the base, it is possible to prevent each of the growth plates from being detached from the base by, for example, a tidal current. Then, when releasing the lock, the lock member may be pulled out from the lock holes provided in each of the growth plates and the base body. In this unlocked state, each growth plate can be easily attached to and detached from the base.

  Furthermore, in the artificial reef according to the present invention, the base body is provided with a bottom plate, a roof portion that is arranged at a distance from the bottom plate, has a substantially cross-shaped planar portion, and projects in each direction of the cross of the roof portion. A side wall portion provided on the bottom plate to support each protrusion and parallel to a protrusion direction of the corresponding protrusion; and the side wall portions provided for each protrusion are spaced apart from each other. It is preferable that the landing plate is provided between the side wall portions facing each other. If comprised in this way, a corner part will be formed between the protrusion parts of a cross-shaped roof part, and the side wall part provided in this corner part will be arrange | positioned at substantially L shape seeing from the plane direction. The Since the tides tend to collide with the side wall portion arranged in an approximately L shape, eddies are likely to be generated, and in this L shape portion, spores of seaweed and flow algae are likely to stay and settle, And seaweed etc. can be propagated in this L-shaped part. The proliferated seaweed and the like serve as food for root resources such as abalone. Then, a tidal current can be caused to flow in through the gap between the growth plates arranged below the protruding portion of the substantially cross-shaped roof portion, and the flowing tidal current is placed below the other protruding portions. It can flow out from the gap between raw plates. As a result, fresh tidal currents can be distributed to abalone and other sone resources.

  In the artificial reef according to the present invention, the roof is provided with an opening, the roof is formed of a ceramic porous member, and the ceramic porous is formed on the outer surface of the side wall or the upper surface of the bottom plate. It is good to attach a member. As described above, when the opening is provided in the roof portion, the tide flowing from the gap between the respective settlement plates can be discharged also from the opening, and thereby, the fresh tide is used as the root resource such as abalone. Can be fully distributed. When the roof portion is formed of a ceramic porous member and a ceramic porous member is attached to the outer surface of the side wall portion or the upper surface of the bottom plate, spores of seaweed and flow algae are formed on the porous member. It can be easily propagated.

  Moreover, in the artificial reef according to the present invention, it is preferable to provide a feed biological growth component formed of a mesh or a large number of stones on the bottom plate of the base. According to this feed organism propagation construct, a large number of fine spaces in the reticulate body serve as a breeding home for the feed organism, and the feed organism can be propagated. According to a large number of stones, a large number of complicated gaps formed between the stones serve as a living place for food organisms and fish, and the food organisms and fish can be propagated. The grown feed organisms serve as a feed for the root source.

  Furthermore, the artificial reef according to the present invention includes a roof tile unit, and the roof tile unit is provided in the frame by arranging a plurality of roof tiles in a substantially horizontal manner and by alternately changing the direction of the front and back surfaces in multiple stages. Preferably, the tile unit is detachably provided on the base plate of the base body, and the tile unit removed from the base plate can be pulled up through an opening provided in the roof portion of the base body. According to this tile unit, since the tiles having a rough surface are arranged substantially horizontally, the root resources can be stably formed on the surface of the tile. In addition, by arranging the tiles alternately in multiple stages with the front and back sides being changed, the space between the tiles can be formed in a size suitable for the cultivation of the root resources. And since the tile unit can be pulled up through the opening provided in the roof portion of the base body, for example, the tile unit such as abalone grown by growing the tile unit to the ground and growing on each tile is collected. Can be easily collected.

  And in the artificial reef which concerns on this invention, the said base | substrate has a roof part, and it is good to form the upper surface of the said roof part as an inclined surface which descend | falls toward an outer periphery. In this way, by making the inclined surface descending as the upper surface of the roof portion moves toward the outer periphery, the fish net can be hardly caught.

  According to the artificial reef of the present invention, since the epiplate is detachably attached to the base body by engaging the concave portion and the convex portion, the epiplate can be easily detached from the base body and removed from the base plate. Root resources can be easily collected. In addition, as described above, it is possible to easily collect the soot resource from the epiphytic plate, so that the operator can easily collect the soot resource from the epithelial plate by hand. It is not necessary to limit the shape of the artificial reef, and the artificial reef can be formed in a desired shape according to the installation location.

  Hereinafter, an embodiment of an artificial reef according to the present invention will be described with reference to FIGS. The artificial reef 8 shown in FIG. 1 can be installed on the seabed, and for example, root resources such as abalone, sazae, sea urchin, sea cucumber, lobster, etc. are discharged to the artificial reef 8 and are allowed to settle.

  As shown in FIGS. 1 and 3, the roof portion 12 is formed by a total of four inclined plates (protruding portions) 14, and the four inclined plates 14 are arranged so as to have a substantially cross shape when viewed from the plane direction. Has been. That is, these four inclined plates 14 are disposed so as to protrude outward in the four directions from the center of the roof portion 12, and are inclined in a direction of descending toward the outer side. And the rectangular opening part 12a is formed in the center part of the roof part 12 formed in this substantially cross shape.

  As shown in FIGS. 1 and 2, four side walls 10 are provided for each of the four inclined plates 14, and support the corresponding inclined plates 14. The side wall portions 10 are arranged to face each other at a predetermined interval, and the corresponding inclined plates 14 are parallel to the direction in which the corresponding inclined plates 14 protrude in the horizontal direction from the center of the roof portion 12. A plurality of deposition plates 9,... Are detachably provided between the side wall portions 10 arranged to face each other. These bottom board 11, roof part 12, and side wall part 10 are bases.

  As shown in FIG. 4, the growth plate 9 is formed so as to be arranged in multiple stages in the vertical direction in a substantially horizontal state, and each edge portion 9 a, 9 a on both sides of each growth plate 9. Is held by a plurality of groove portions 10 a provided in the side wall portion 10. These growth plates 9 have the same shape, and are rectangular plates that are long in the depth direction, as shown in FIG. The lateral width of the deposition plate 9 is formed such that it can be mounted in the groove portions 10a and 10a provided on the wall surfaces of the two side wall portions 10 and 10 to which the deposition plate 9 is attached.

  As shown in FIG. 5A, a large number of the groove portions 10a are provided on the wall surface of the side wall portion 10, and the interval in the vertical direction is, for example, 50 mm. As described above, since a large number of the groove portions 10a are provided, as shown in FIG. 4, according to the size of the root resource such as abalone that grows on the growth plate 9, the growth plate 9 is formed in an appropriate groove portion 10a. Can be used.

  Further, as shown in FIG. 4, a locking device 15 is provided for locking the growth plate 9,... Mounted between the side wall portions 10 and 10 to the side wall portions 10 and 10. Yes. The locking device 15 is capable of collectively locking, for example, the growing plates 9 mounted in multiple stages in the vertical direction between the side wall portions 10 and 10 on the side wall portion 10. 14, the respective retaining holes 9, 17, 18 provided in the respective stationary plates 9 and the bottom plate 11, and the respective retaining holes 16, 17, 18 are inserted into the side wall portions. 10 and a rod-shaped locking member 19 for locking to the motor 10.

  As shown in FIG. 4, each locking hole 17 provided in each of the growth plates 9 is a long hole (through hole) having a size that can be handled, for example, and the front edge of the growth plate 9. One is formed at a substantially central position of the part. The reason why the locking hole 17 is formed as a long hole is that when the operator pulls out the attachment plate 9 mounted on the side wall 10 or mounts it on the side wall 10, This is because it can be hung and can be easily put in and out.

  As shown in FIG. 4, the locking holes 16 and 18 provided in the inclined plates 14 and the bottom plate 11 are, for example, circular holes (through holes). Each of the locking holes 16 and 18 has a size that allows the locking member 19 to be inserted therethrough.

  As shown in FIG. 4, the locking member 19 includes a rod-shaped portion 19 a having a predetermined length, and an annular handle 19 b is provided at the upper end. The rod-shaped portion 19a has a thickness and a length that can be inserted into the respective locking holes 16, 17, and 18 formed in the inclined plate 14, the plurality of deposition plates 9, and the bottom plate 11, and this insertion is performed. In this state, the handle 19b provided at the upper end comes into contact with the upper surface of the inclined plate 14, and the locking member 19 is held. Thus, by inserting the locking members 19 into the respective locking holes 16, 17, 18, each of the deposition plates 9, ... can be locked to the corresponding side wall portions 10, thereby For example, each of the growing plates 9 can be prevented from being detached from the side wall portion 10 by the tidal current 27 or the like.

  FIG. 6 shows a structure in which the inclined plate 14 constituting the roof portion 12 is fixed and attached to the upper end portion of the side wall portion 10 by, for example, anchor bolts 20. These inclined plates 14 are formed of, for example, a ceramic porous member. 1, 2, and 6, a ceramic porous member 21 is fixed and attached to each of four corners of the outer surface of the side wall portion 10 and the upper surface of the rectangular bottom plate 11 with anchor bolts 20. It is. The porous members 14 and 21 made of ceramic are, for example, crushed roof tiles bonded with cement paste, and the porosity is, for example, about 25%, and the voids communicate with each other.

  The intricately shaped gaps formed in the porous member 21 are suitable for living places such as microorganisms, raw starting materials, polychaetes and crustacean larvae, and seaweeds such as seaweed spores and flow algae. It is excellent as a thing to settle. These microorganisms and seaweeds serve as feed for root resources such as abalone growing on the respective growth plates 9, and are used for growing and growing the root resources.

  Then, as shown in FIG. 2, a stone housing bar 22 is provided at the center of the bottom plate 11. A large number of stones (for example, chestnuts) 23,. The weight of the chestnut 23 also functions to stably install the artificial reef 8 on the seabed. And since many crevices of complicated shape are formed between many chestnuts 23, each crevice becomes a dwelling place of a feed organism and fish, and it can promote reproduction of a feed organism and fish.

  In addition, the deposition plate 9 is made of, for example, plastic or a lightweight metal subjected to rust prevention treatment, and the locking member 19 is made of, for example, stainless steel. The side wall part 10 and the bottom board 11 are integrally formed, for example with concrete. The length of one side of the bottom plate 11 is about 3.5 m, for example.

  The artificial reef 8 shown in FIG. 1 and the like configured as described above can be installed on the seabed, for example. Then, for example, by discharging the root resources (not shown) including abalone and tuna into the artificial reef 8, these root resources are grown on the upper and lower surfaces of a large number of settlement plates 9. be able to. Then, after the grown root resources such as abalone grow, these root resources can be collected.

  That is, when collecting the grown abalone and other root resources from the deposition plate 9, the locking member 19 shown in FIG. 4 may be pulled up and pulled out from the locking holes 16, 17 and 18. As a result, the locking of each of the growing plates 9 with respect to the side wall 10 can be released, and each of the growing plates 9 can be easily pulled out from the groove 10a of the side wall 10 and removed. Therefore, it is possible to easily collect the root resources from the removed growth plate 9.

  Then, after collecting the root resources, as shown in FIG. 4, the respective deposition plates 9 are inserted into the respective groove portions 10 a provided in the side wall portions 10 and attached. Then, by inserting the locking members 19 into the respective locking holes 16, 17, 18, it is possible to easily lock the respective deposition plates 9 so as not to be detached from the side wall portions 10.

  Thus, by using this locking device 15, each of the deposition plates 9 can be easily locked with respect to the side wall portion 10, and the locking can be easily released. Then, when the locking is released, each of the growth plates 9 can be easily attached to or removed from the side wall portion 10, and each of the growth plates 9 can be removed by removing each of the growth plates 9. It is possible to easily collect the root resources from 9. In addition, as described above, it is possible to easily collect the root resource from the growth plate 9, so that the worker can easily collect the root resource from each of the growth plates 9 by hand. 9 and the shape of the artificial reef 8 as a whole need not be limited, and the artificial reef 8 can have a desired shape according to the installation location.

  And as shown in FIG. 4, since it was set as the structure which can arrange | position the growth plate 9 in multiple steps to the up-down direction, the installation area of this artificial reef 8 can be made small, and an operator can use a soot resource. Can be released to cause the root resources to grow on each of the growth plates 9, or when the root resources can be collected from each of the growth plates 9, the moving distance for work can be shortened. In addition, since the growth plate 9 is mounted substantially horizontally, the root resources are easily formed on the growth plate 9.

  However, although not shown in the drawing, each groove portion 10a may be formed to be inclined, and each of the growth plates 9 may be arranged to be inclined. In this way, it is possible to make it difficult for dirt and the like to accumulate on each of the growing plates 9, and it is possible to easily collect the root resources without the earth and sand getting in the way.

  Furthermore, as shown in FIG. 4, since the many groove parts 10a provided in the side wall part 10 are provided in multiple stages in the height direction, the space | interval of the upper and lower epidemic plates 9 is large of a root resource. The formation plate 9 can be mounted in a desired groove 10a so as to be formed accordingly.

  As shown in FIG. 1, corner portions 24 are formed between the inclined plates 14 of the roof portion 12 having a cross-shaped planar shape, and the side wall portions 10 provided at the respective corner portions 24. 10 are arranged in an L shape when viewed from the plane (see FIG. 2). Since the tidal current 27 collides with the L-shaped side wall portions 10 and 10 and the vortex 25 is likely to be generated, spores of seaweeds, flow algae and the like are easily accumulated in the L-shaped portion. Therefore, seaweed etc. can be propagated in this L-shaped part. The proliferated seaweed and the like serve as food for root resources such as abalone. And the tidal current 27 can be made to flow in from the clearance 26 between the growth plates 9 arranged below the inclined plate 14 that forms the roof portion 12, and this inflowed tidal current 27 is placed below the other inclined plates 14. It can be made to flow out from the gaps 26 between the placed plates 9. As a result, the fresh tidal current 27 can be spread over the root resources such as abalone. This makes it possible to grow the root resources efficiently.

  Moreover, since it was set as the structure which provided the opening part 12a in the center part of the roof part 12 as shown in FIG. 1, the tidal current 27 which flows in from the clearance gap 26 between each growth plate 9 is also made to flow out from this opening part 12a. In this way, the fresh tide 27 can be sufficiently distributed to root resources such as abalone. And since the tidal current 27 can pass through the artificial reef 8 in this manner and the vortex 25 is likely to be generated in the L-shaped portion of the side wall portion 10, the roof portion 12 made of a porous member or In addition, seaweed spores, flow algae, and the like can be easily grown on the porous member 21 attached to the outer surface of the side wall portion 10 and the upper surface of the bottom plate 11 and can be propagated. These seaweeds and the like serve as food for prey organisms and root resources, and can efficiently grow and proliferate the root resources.

  Furthermore, as shown in FIG. 1, according to the artificial reef 8, the planar shape of the roof portion 12 is substantially cross-shaped, and each inclined plate 14 constituting the roof portion 12 is inclined in a descending direction toward the outside, Since the horizontal outer edge portion of each inclined plate 14 is joined and connected to the vertical outer edge portion of the side wall portion 10, the fish net can be hardly caught on the artificial reef 8.

  However, in the said embodiment, as shown in FIG. 2, many chestnuts 23 were arrange | positioned in the center part of the bottom board 11, but it replaces with this and feed biological growth structure 28 as shown to Fig.7 (a) is used.

A net-like body (not shown) such as a fish net is folded and accommodated in a substantially cubic inner space formed by the net member 32. A large number of minute spaces in the reticulate body serve as a place for breeding of feed organisms, and the feed organisms can be propagated. The grown feed organisms serve as a feed for the root source.

  In addition, in the feed biological growth construct 28 shown in FIG. 7A, a large number of the breeding construct units 30 shown in FIG. 7B are arranged in the outer frame 29. Instead of this, a configuration in which a large number of roof tile units 33 shown in FIG. 8 are arranged in the outer frame body 29 (sone resource multiplication component (not shown)) may be employed. As shown in FIG. 8, each roof tile unit 33 is arranged in the inner frame 31 by arranging a plurality of roof tiles 35 in a substantially horizontal manner, alternately changing the front and back orientations in multiple stages in the vertical direction. It is a configuration. According to the roof tile unit 33, the roof 35 having a rough surface is disposed substantially horizontally, so that the root resources can be stably formed on the top surface of the roof tile 35. Further, by arranging the tiles 35 in multiple stages by alternately changing the front and back directions, the space between the tiles 35 can be formed in a size suitable for growing the ridge resources 36.

  Then, as shown in FIG. 7A, four hanging portions 37,... Are welded to the upper surface of the outer frame body 29. Using this suspension part 37, the feed biological growth component 28 or the root resource propagation component is suspended and passed through the opening 12a formed in the roof part 12 so as to be detachable on the bottom board 11. can do. For this purpose, the opening 12a is formed to have a size larger than those of the feed biological growth component 28 and the root resource propagation component.

  In addition, the root resource propagation component can be lifted and pulled up through an opening 12 a provided in the roof portion 12. Therefore, for example, the root resource propagation constituents can be lifted to the ground, and the root resources such as abalone grown and grown on the respective roof tiles 35 can be easily collected.

  Furthermore, in the said embodiment, as shown in FIG. 4, by inserting the edge parts 9a and 9a of the hardening plate 9 in the groove parts 10a and 10a provided in the side surface of the side wall parts 10 and 10, this hardening plate 9 is provided.
