Description

  The present invention relates to a driftwood stop facility provided in front of a drainage gate or a driftwood for preventing a dust or driftwood from flowing into a water intake of a reservoir or a dam lake, a ship gate used for a dam incidental facility or other floating structure, More specifically, the present invention relates to a U-shaped gate frame that is supported in a semi-submersible shape by a float and is provided with a gate rod that can be rotated like a breaker around a single point.

  For example, as shown in FIG. 1, a passing gate B is used in the middle of a driftwood stop A installed in a reservoir or a dam lake so that a dust collector or a patrol boat can pass through. It prevents the flow of dust, driftwood, etc., and opens the gate to pass the ship when passing.

This ship gate B is, for example, by placing a door slidable up and down on a U-shaped frame supported in a semi-submersible shape by a float, and by raising and lowering a wire rope that suspends this door, The door is opened and closed (see Patent Document 1).
Japanese Patent Publication No. 2-16810

  According to the passing gate shown in Patent Document 1, since the movable part such as the wire rope and the roller that hangs the wire rope is located in the water, there is a case where dust, driftwood, etc. are caught and do not operate. Moreover, there was a fault that there were so many failures. In addition, there are not only a large number of parts such as wire ropes and rollers, but also a large number of custom-made products, so there is a fatal drawback of high cost.

  The present invention aims to eliminate these drawbacks, and can be operated like a circuit breaker around a single point on a U-shaped gate frame supported in a semi-submersible shape by a float. A gate trough is provided, and a net that opens and closes the entrance and exit formed by the gate frame when the gate trough is opened and closed is attached to the gate trough.

  When the gate fence blocks the U-shaped gate frame, as shown in FIG. 3, the net attached to the gate fence closes the doorway formed by the U-shaped gate frame. Therefore, it is possible to prevent dust and driftwood from flowing. On the contrary, as shown in FIG. 4, when the gate rod is operated and raised around one point, the net attached to the gate rod is also lifted and formed by the U-shaped gate frame. Since the doorway to be opened is open, it is possible to pass.

  According to this configuration, the number of parts can be reduced, and since it is not necessary to use a custom-made product, not only can the cost be reduced, but also the assembly and installation time can be shortened. Weight reduction can be achieved.

  It is desirable that the rotation center of the gate rod is positioned above the water surface. In this case, since the pivotal portion of the gate rod which is a movable part is located above the water surface, there are few failures. Even if it breaks down, it can be repaired on the water, so it can be repaired easily.

It is desirable that the operating means of the gate rod is a winch, which is disposed above the water surface and that the wire rope tip side of the winch is attached to the gate rod. When the winch is actuated and the wire rope is wound up, the gate rod is turned up around one point, and the net attached to the gate rod is also lifted and formed by the U-shaped gate frame. You can open the doorway. On the contrary, when the wire rope is fed out, the gate rod turns and lowers around one point, and the net attached to the gate rod closes the entrance / exit formed by the U-shaped gate frame.
In these cases, since the winch which is a movable part is located above the water surface, there are few failures. Even if it breaks down, it can be repaired on the water, so it can be repaired easily.

  It is desirable to hold the left and right sides of the net suspended from the gate cage with a net disturbance prevention guide. If the left and right sides of the mesh body suspended from the gate cage are held by the mesh disturbance prevention guide, the mesh body suspended from the gate cage will hang straight from the external force such as wind and waves. Since it can be prevented from moving unnecessarily, the functions of the floating wood structure, the dam-attached equipment, and other floating structures are not impaired, and the function can be maintained even during stormy weather.

  It is preferable to be able to bend the middle of the network disturbance prevention guide. In this way, when the gate rod is activated and raised, the network disturbance prevention guide extending from the gate rod is bent halfway, and between the gate rod and the bent mesh disturbance prevention guide. Thus, since one net is folded, the total weight of the net is appropriately dispersed, and the network disturbance preventing guide is not broken.

  According to the first aspect of the present invention, the number of parts can be reduced, and a custom-made product need not be used. Therefore, not only can the cost be reduced, but also the assembly and installation time can be shortened. In addition, the weight can be reduced.

  According to the invention described in claim 2, since the pivoting portion of the gate rod which is a movable part is located above the water surface, there is little failure, and even if it should break down, it can be repaired on the water. Repair can be done easily.

  According to the invention described in claim 3, since the winch which is the movable part is located above the water surface, there is little failure, and even if it breaks down, it can be repaired on the water. be able to.

  According to the fourth aspect of the present invention, since the net suspended from the gate fence can be prevented from moving unnecessarily from the state of being drooped straight by an external force such as wind or wave, it is possible to prevent driftwood stoppers and dam attachments. The functions of the facilities and other floating structures are not impaired, and the functions can be maintained even during stormy weather.

  According to the fifth aspect of the present invention, when the gate rod is activated and raised, the mesh body disturbance prevention guide extending from the gate rod and holding the side edge of the mesh body is bent halfway, Since one mesh body is folded between the gate cage and the folded mesh body disturbance prevention guide, the entire weight of the mesh body is appropriately dispersed, and the network body disturbance prevention guide is not broken. .

Preferred embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the driftwood stopping facility A is installed in front of a water intake such as a reservoir or a dam lake, and a passing gate B is provided in the middle thereof. 2 and 3 show an outline of the ship gate B of the present invention.

  Here, a U-shaped gate frame 2 supported in a semi-submersible manner by two floats adjacent to the front and rear on the left side and four floats (shown by the same reference numeral 1) adjacent to the front and rear and the right and left on the right side is arranged. Further, there is illustrated a passing gate provided with a gate rod 3 that can be operated like a breaker around the horizontal axis 3a at the upper end of the gate frame 2.

A rectangular net 4 that opens and closes the entrance 2a formed by the gate frame 2 when the gate frame 3 is opened and closed is attached to the gate frame 3 so as to hang down in the longitudinal direction of the gate frame 3. For example, as shown in FIG. 5, one net 4 can be suspended from the gate cage 3 by binding the upper edge of the square mesh 4 to the gate cage 3 with a binding rope 4a. The net body 4 can be made of polyethylene or other synthetic resin.

The shaft 3a serving as the rotation center of the gate rod 3 is held by a holding member 5a on the platform 5 located above the water surface W.
When the pivoted portion of the gate rod 3 that is the movable portion, that is, the axis 3a that is the rotation center of the gate rod 3 is located on the platform 5 that is located above the water surface W, the movable portion is below the water surface W. There is much less failure than if it is located. Even if it should break down, it can be repaired on the platform 5 located above the water surface W, so that the repair can be easily performed.

  The platform 5 is disposed on four floats adjacent to each other on the right and left sides in FIGS. 2 to 4 and on two floats adjacent to each other on the left side in FIGS. Note that handrails 6 are erected on the inner sides of the left and right platforms 5 and 5 (both sides close to the gate frame 2).

  Here, the case where the winch 7 is used as a means for operating the gate rod 3 around the shaft 3a is illustrated. The winch 7 is attached to the attachment member 5b on the platform 5 located above the water surface W, and the tip end side of the wire rope 7a wound around the drum of the winch 7 is provided at the upper end of the attachment member 5b. It is attached to the gate trough 3 via a roller 7b.

  When the winch 7 is actuated and the wire rope 7a is wound around the drum, as shown in FIG. 4, the gate rod 3 is actuated and rises around the shaft 3a, and is attached to the gate rod 3 The net 4 is also lifted, and the entrance / exit 2a formed by the U-shaped gate frame 2 can be opened. Conversely, when the wire rope 7a is unwound from the drum, the gate rod 3 is actuated and lowered around the shaft 3a, and as shown in FIG. 3, the rectangular net 4 attached to the gate rod 3 is provided. Closes the entrance 2a formed by the U-shaped gate frame 2.

  In this way, when the winch 7 as a means for operating the gate rod 3 around the horizontal axis 3a is positioned further above the platform 5 positioned above the water surface W, the movable part becomes the water surface. There are far fewer failures than when located under W. Even if it should break down, it can be repaired on the platform 5 located above the water surface W, so that the repair can be easily performed.

  In the case of the automatic passing gate illustrated here, the number of parts constituting the gate and the part including the power source for operating the gate rod can be reduced, and it is not necessary to use a custom-made product and is listed in the catalog. Therefore, not only can the cost be reduced, but also the assembly and installation time can be shortened, and the weight can be reduced.

The left and right side edges of one net 4 hanging from the gate rod 3 are held by two left and right net disturbance preventing guides 8 and 8. The two left and right mesh body disturbance prevention guides 8 and 8 are extended in a right angle direction from one gate rod 3 with an interval corresponding to the lateral width of the square mesh body 4, for example, as shown in FIG. As shown, the left and right side edges of one net 4 are bound to the left and right side edges of one net 4 by tying the left and right side edges of one net 4 to both nets disturbance prevention guides 8 and 8 with binding ropes 4a and 4a It can be held by two mesh body disturbance prevention guides 8 and 8.
The “disturbance” of the mesh body 4 means that the mesh body 4 suspended from the gate cage 3 moves from a state where it is drooped straight by an external force applied to the mesh body 4 such as wind and waves.
In this way, when the left and right edges of the net body 4 suspended from the gate cage 3 are held by the two left and right mesh body disturbance prevention guides 8 and 8, one sheet suspended from the gate cage 3 It is possible not only to prevent the net body 4 from moving from a state where it hangs down straight due to external forces such as wind and waves, but also to prevent it from shaking violently.

  Here, the upper ends of the two left and right mesh body disturbance prevention guides 8 and 8 are fixed to one gate rod 3 so that both of them can be bent, and the left and right mesh body disorder prevention is prevented. The case where the left and right lower corner portions of one net 4 that is suspended from the gate cage 3 are fixed to the lower ends, which are free ends of the guides 8 and 8, is illustrated. For example, if one mesh body disturbance prevention guide 8 is divided into at least two parts at the top and bottom, and the abutting portions of both are pivotally attached to each other by hinge pins 9, as shown in FIG. The middle of the prevention guide 8 can be bent.

  In this way, when the gate rod 3 is activated and raised, the two network disturbance prevention guides 8 and 8 extending from the gate rod 3 are in the middle as shown in FIG. Since the one net 4 is folded between the gate cage 3 and the two left and right net disturbance preventing guides 8, 8, the total weight of the net 4 is moderate. The network disturbance preventing guide 8 that is dispersed and located at least on the upper side does not break.

  Reference numeral 10 is a control panel installed on the platform 5, and 11 is a solar cell also installed on the platform 5. The winch 7 can be automatically operated by remote control, so that the gate cage 3 Can be opened and closed from a distance. Reference numeral 12 is a net suspended from the platform 5, and reference numeral 13 is a pair of upper and lower connecting pins attached to the left and right sides of the automatic ship gate B. The automatic ship gate B is used for the net. When used as a network, the netting field can be connected.

  This automatic passing gate B is used for driftwood stoppers installed in front of the intakes of reservoirs, dam lakes, etc. to prevent intake of driftwood, driftwood, etc. Alternatively, it can be used as a ferry gate.
