Japanese Patent No. 3757201 (pages 5 and 6, FIGS. 2 to 7)

However, the above-mentioned ship gate has the following problems.
(1) Since it is always floating on the surface of the water, when used in a dam lake, if the water level drops due to drought, etc., it may fall over in contact with the bottom of the lake and be damaged. In addition, it is easily damaged by strong winds and high waves due to bad weather.
(2) Maintenance is troublesome because the structure is complicated.
(3) Since the door is automatically closed except when the ship is passing, it is difficult to continuously distribute water between the two water bodies.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a passing gate that has a simple structure and can be retreated into water as needed.

  The passage gate according to claim 1 is a passage gate that allows passage of a ship through a part of a float member that divides a water area into two, and is formed in a horizontally long shape and can be supplied and exhausted into a hollow interior. A regulation that provides a flexible float / float type float, suspends a skirt with a weight over the entire length of the float / float float, and regulates the sinking distance from the water surface at both ends of the float / float float The float is connected by a connecting line while maintaining an interval corresponding to the width of the ship, and a core material is disposed along the longitudinal direction between the regulation floats of the float-float type float.

  According to the ship gate according to the first aspect, when the gas is discharged from the inside of the float / float type float and the buoyancy is lowered, the float / float type float sinks in water and is partitioned by the pollution prevention device or the like. The two water areas are in communication and the ship can pass. Since the core material is disposed between the regulation floats of the float / float type float, the width of the passage does not decrease due to the slack of the float / float float, and the water depth is kept constant by the regulation float. Therefore, a predetermined passing space is always formed at the time of opening, and smooth passing can be performed. In addition, since it can be submerged in water as needed, it can be temporarily evacuated to avoid damage due to bad weather, etc., and it is also possible to continuously distribute water between the partitioned water areas. It is. Thus, since the gate is opened and closed by the rising and falling of the float-float type float, the structure is simpler than that of a conventional passing gate.

  The float member means a float member such as a pollution prevention device, an oil fence, a driftwood stopper, etc., and the skirt portion includes a water-permeable curtain body that prevents the diffusion of pollution, and oil that has flowed out. Including a non-permeable curtain body that prevents the diffusion of water, a net-like curtain body that collects driftwood, and the like, and the pollution control device includes an oil fence and a driftwood stopper.

  The ship gate according to claim 2 is characterized in that a material that sinks in water is used for the core material. According to the ship gate according to the second aspect, since the sinking of the floating float between the regulation floats can be promoted, the gate can be opened quickly.

  The passage gate according to claim 3 is a passage gate that allows passage of a ship through a part of a float member that divides a water area into two, and the passage gate is formed in a horizontally long shape and has a hollow interior. Is provided as a part of a flexible float / float float that can be supplied and exhausted, and a skirt portion having a weight is suspended over the entire length of the float / float float. A pair of regulating floats that regulate the sinking distance are connected by a connecting rope while maintaining a distance corresponding to the width of the ship, and a core material is disposed along the longitudinal direction between the regulating floats of the floating and sinking float. The weight of the weight is increased between the regulation floats, or at least one of a material that sinks in water is used for the core material.

  According to the passing gate according to claim 3, buoyancy is reduced by discharging gas from the inside of the float / float type float, and the weight is made heavy or the core material is made of a material that sinks in water. Accordingly, the space between the regulation floats of the float / float type float that is promoted to sink is submerged in water before others. As a result, the two water areas partitioned by the pollution control device or the like are brought into communication with each other, and the passage of the ship becomes possible. The amount of gas discharged from the float / float type float is set to such an extent that only the regulated float sinks.

  Since the core material is disposed between the control floats of the float / float type float that has submerged in water, the width of the ship does not decrease due to the slack of the float / float type float, and the water depth is reduced by the control float. Since it is kept constant, a predetermined ship passing space is always formed at the time of opening, and smooth ship passing can be performed. In addition, since the entire length of the float / float type float including the passing gate can be submerged as necessary, it is possible to temporarily retreat into the water to avoid damage due to bad weather, and the partitioned It is also possible to circulate water continuously between water bodies. Thus, since the gate is opened and closed by the rising and falling of the float-float type float, the structure is simpler than that of a conventional passing gate.

  According to a fourth aspect of the present invention, the ship gate is provided with an air supply / exhaust port at one end in the longitudinal direction of the float / float type float, and one end is connected to the air supply / exhaust port inside the float / float type float. A flexible tube extended to an end located opposite to the exhaust port is disposed, and a plurality of vent holes are scattered and provided on the outer peripheral surface of the flexible tube.

  According to the ship gate according to claim 4, the structure can be simplified by providing the air supply / exhaust port at either one of the both ends of the float / float type float, and the gas in the float / float float It is possible to avoid the lack of settlement due to the residue. That is, when the air is exhausted from the float / float type float, the buoyancy gradually decreases, and the float / float type float gradually sinks into water. The float / float type float that has been submerged in water is crushed by water pressure as the gas is released, making it difficult for the gas to flow inside. Due to this, gas is likely to remain at the end located opposite to the air supply / exhaust port where gas is difficult to escape. Therefore, by disposing the flexible tube, it is possible to discharge the internal gas even when the floating float is crushed by water pressure.

  The ship gate according to the first aspect of the present invention is 1) Since the structure is simple, it does not take time to design and manufacture and is easy to maintain. 2) Since the core material is provided between the control floats of the float / sink type float, and the subsidence depth is kept constant by the control float, the prescribed space for passing even when the conditions are bad, such as when waves are standing on the water surface Is secured, and smooth cruising can be performed at all times. 3) Durability is improved because it is not easily damaged by bad weather, and can be used for a long time. 4) Since it is possible to continuously circulate water between two water areas as necessary, for example, when used in a dam lake, fresh water flowing from an upstream river in normal times can flow downstream without clogging. it can. 5) Since it can be kept submerged in water, it can be stored in water with other floats if a pollution control device (for example, including an oil fence or driftwood stopper) is not required. .

  The ship gate according to claim 2 uses a material that sinks in water as the core material, so that the floating of the floating float between the regulated floats can be performed quickly, and the ship can be completed in a short time. The outflow of suspended matters can be suppressed.

  In addition to the effect of the passing gate according to claim 1, the passing gate according to claim 3 can be provided by improving a part of an existing floating / floating type float member. A ship gate can be installed without the need for

  Since the ship gate according to claim 4 can simplify the structure, the cost can be suppressed, and the space between the regulation floats in the float / float type float is surely sunk, so that the ship can always be smoothly passed.

  Embodiments of a passing gate according to the present invention will be described below with reference to FIGS.

  FIG. 1 is a partially enlarged view of a pollution prevention device 2 provided with a passing gate 1 and is a front view showing a state where it is installed on a water surface. The pollution prevention device 2 is suspended over the entire length of a fixed float (float member) 5 in which a plurality of cylindrical foamed polystyrenes 4 are sequentially stored sideways in a horizontally long cover 3 made of waterproof cloth, and the fixed float 5. It consists of a pollution prevention curtain (skirt part) 6. The pollution prevention curtain 6 sews a water-permeable cloth material into a rectangular shape, attaches a weight chain 7 to one edge of a pair of opposing sides, and lowers the lower end of the fixed float 5 at the other edge. It is connected to. This pollution prevention device 2 is installed in a state where a fixed float 5 is floated on a water surface and a water area is partitioned into two to prevent the inflow and diffusion of polluted water.

  The passage gate 1 is configured by using a rubber float / float type float 8, and a pollution prevention curtain 9 is suspended on the float / float type float 8 in the same manner as the fixed float 5.

  The float / float type float 8 is formed in a horizontally long shape, and a cross-sectional shape perpendicular to the longitudinal direction is an annular shape and includes a hollow interior 10. The hollow interior 10 can be supplied and exhausted. It has become. And it is connected with the fixed float 5 at the both ends of the longitudinal direction, respectively. As shown in FIG. 2, an air supply / exhaust port 11 is provided at one end in the longitudinal direction, and an air pipe 12 is connected thereto. A short exhaust pipe is branched from the air pipe 12, and an air valve 14 is interposed in the branch pipe 13. Reference numeral 15 in the figure denotes a control air pipe that supplies compressed air for operating the air valve 14. On the other hand, as shown in FIG. 3, another air supply / exhaust port 16 is provided at the end opposite to the side where the air supply / exhaust port 11 is provided. 17 is attached and closed. In this way, the structure is simplified by supplying and exhausting air from only one air supply / exhaust port 11. However, for example, when the total length of the float / float type float 8 is long and it takes time to supply and exhaust, there is an advantage that the supply / exhaust can be performed quickly by using both the supply / exhaust ports 11 and 16. The embodiment is shown in FIG. Since the configuration on the air supply / exhaust port 16 side is the same as that on the air supply / exhaust port 11 side, each component is denoted by the same reference numeral and the description thereof is omitted to avoid duplication.

  The pollution prevention curtain 9 is the same as that suspended from the fixed float 5, and is connected to the pollution prevention curtain 6 suspended from the fixed float 5 at both ends. A weight chain 17 similar to the pollution prevention curtain 6 of the fixed float 5 is attached to the lower end portion.

  Regulating floats 18 and 19 for regulating a sinking distance from the water surface are connected to both ends of the float / sink type float 8 by connecting ropes 20 and 21 while maintaining an interval corresponding to the passage width W, respectively. These regulation floats 18 and 19 are made of hard resin, are formed in a shape in which both end openings of a cylindrical body are closed with a hemispherical shell lid, and air is sealed inside. The lengths of the connecting ropes 20 and 21 are set so that the depth of sinking is as shallow as possible so that the sinking float 8 can float in a short time without hindering passage. The core material 22 is disposed along the longitudinal direction of the float / sink type float 8 in the float / sink type float 8 between the regulation floats 18 and 19.

  The core member 22 is a rod-shaped member having a cross-sectional shape such as a rectangle or a circle formed of a hard resin, and is provided by being built in the float / float type float 8 or fixed to the outer surface. As the material of the core member 22, fiber reinforced plastic, metal material, wood, or the like can be used. In particular, since it becomes a weight by using a material that sinks in water, the sinking of the float / float float 8 can be promoted, and rapid passage is possible.

  Next, the operation of the passing gate 1 will be described with reference to FIG. As shown in FIG. 5 (a), the floating float 8 floats on the surface of the water while the ship is not in operation, preventing the outflow of polluted water and suspended matter. Then, when the ship is made to approach the ship gate 1 for ship passing and the ship gate 1 is opened by a remote controller (not shown), or the monitoring tower is requested to open the ship gate 1 wirelessly, the air valve 14 Compressed air is supplied from the control air pipe 15, the air valve 14 is opened, and the air inside the float / float type float 8 is gradually discharged from the branch pipe 13. When air is discharged from the interior 10, the buoyancy is gradually lost, and the float / float type float 8 sinks into the water as shown in FIG. 5 (b). When the subsidence depth reaches the length of the connecting lines 20 and 21, the float / float type float 8 is suspended in the water by the pair of regulation floats 18 and 19, and the subsidence stops. Completion of the settlement can be confirmed by the regulation floats 18 and 19 being in a state of floating on the water surface with the longitudinal direction thereof set to the vertical direction. That is, since the connecting ropes 20 and 21 are connected at one end portion in the longitudinal direction, the end portion on the connecting rope side faces downward when the floating float 8 sinks.

  The floated / floating type float 8 that has been sunk does not sag between the regulated floats 18 and 19 due to the provision of the core member 22, and the prescribed ship width W is ensured and is held at a constant water depth by the regulated floats 18 and 19. Therefore, a predetermined ship passing space is always formed at the time of opening. Accordingly, the ship can smoothly pass through the passing gate 1 even under adverse conditions such as when waves are standing on the water surface. On the other hand, when the core member 22 is not provided, as shown in FIG. 11, the passage width W 'is reduced and the passage space is narrowed to prevent passage. When the passing is completed, an operation for closing the passing gate 1 is performed with a remote controller, or the monitoring tower is requested to close. Then, compressed air is supplied to the air valve 14 through the control air pipe 15 and the branch pipe 13 is closed. Next, air is supplied from the air supply / exhaust port 11 to the inside 10 of the float / float type float 8 through the air pipe 12. When air is supplied, the buoyancy of the float / float type float 8 gradually increases and begins to float toward the water surface. When the float / float type float 8 completely floats on the water surface, the supply of air is stopped, and the passing gate 1 is closed again.

  In this ship gate 1, in order to prevent air from remaining in the interior 10 of the float / float type float 8, as shown in FIG. 6, a flexible tube provided with a plurality of air holes 24 scattered on the outer peripheral surface. 23 can be disposed in the interior 10. The flexible tube 23 is made of a pressure-resistant rubber hose or the like. One end of the flexible tube 23 communicates with the air supply / exhaust port 11 (see FIG. 6A), and the other end extends to the end located opposite to the air supply / exhaust port 11. Provide an extension (see FIG. 6 (b)). As a result, even when the float / float type float 8 is submerged in water and crushed by water pressure, the air in the interior 10 can be discharged through the flexible tube 23, so that no air remains in the interior 10. The floating float 8 can be surely submerged in water.

  The passing gate 1 ′ according to the present invention can be provided as a part of the long floating float 8. Hereinafter, the same or corresponding components as those of the above-described passing gate 1 are denoted by the same reference numerals, and description thereof is omitted to avoid duplication. 7 has a configuration in which a plurality of float-float type floats 8 are sequentially connected, and a pollution prevention curtain 9 is suspended from each float-sink type float 8. A plurality of auxiliary floats 25 are connected to the float / float type float 8 by connecting ropes 26 at predetermined intervals (see FIG. 10). The auxiliary float 25 is formed in a barrel shape using a hard resin, and air is sealed inside. With these auxiliary floats 25, the subsidence float / float type float 8 is regulated so as not to be below a predetermined water depth. Each connecting line 26 of the auxiliary float 25 is set longer than the connecting lines 20 and 21 of the regulation floats 18 and 19.

  The passing gate 1 ′ is provided in one of the float and sink type floats 8, and the connecting rope 20 with a pair of regulating floats 18 and 19 providing a distance of the passing width W at a position to be the passing gate 1 ′. , 21 (see FIG. 8). A rod-shaped core member 22 ′ is disposed along the longitudinal direction of the float / sink type float 8 between the regulation floats 18 and 19. Since the material of the core member 22 ′ is iron, the settlement between the regulation floats 18 and 19 in the float / sink type float 8 can be promoted, and the space between the regulation floats 18 and 19 can be lowered before others. The core material 22 ′ can be any material other than iron as long as it sinks in water. Further, even if the weight of the pollution prevention curtain 9 between the regulation floats 18 and 19 is increased, the same effect can be obtained.

  In this way, the float / sink type float 8, which is partly the passing gate 1 ′, performs air supply / exhaust using only one air supply / exhaust port as in the above-described embodiment in order to simplify the structure. Yes.

  Next, the operation of the ship gate 1 'will be described. In the case of passing a ship from the ship gate 1 ′ of the pollution control device 2 ′, a predetermined amount of air is discharged from the interior 10 of the float / float type float 8. Then, the space between the regulation floats 18 and 19 where the core member 22 ′ is provided in the float and sink type float 8 begins to sink before the others, and reaches the water depth set by the connecting lines 20 and 21 of the regulation floats 18 and 19. Then, it will be suspended in the water by the regulation floats 18 and 19, and the settlement will stop. When it is confirmed that the regulation floats 18 and 19 are vertically oriented and the settlement of the float / float type float 8 is completed, the air discharge is stopped and the ship is made to pass from the open ship gate 1 '. When the ship is completed, air is supplied to the inside of the float / float type float 8, the float / float type float 8 is floated on the water surface again, and the ship gate 1 ′ is closed.

  In addition, when the total length of the float / float type float 8 provided with the passing gate 1 ′ is relatively long as in the pollution prevention device 2 ′, the float / float type float 8 is removed by supplying and exhausting air from both the air supply / exhaust ports. Since it can float and sink quickly, the time required for passing a ship can be shortened.

  In addition, the pollution prevention device 2 ′ discharges air from the inside 10 of each float / float type float 8 when large-scale water discharge occurs or damage is expected due to high waves due to bad weather such as a typhoon. Can be evacuated into water. As shown in FIG. 11, each float / float type float 8 submerged in the water is suspended in the water by the auxiliary float 25 so that it cannot be beaten by the water flow. When the weather recovers, air is supplied to the inside 10 of each float / float type float 8 and floats again on the water surface.

  In the above embodiment, the transit gate 1 'is provided only in one of the float / float type floats 8, but it can also be provided in another float / float type float 8 or when the full length of the float / float type float 8 is long. A plurality of ship gates 1 ′ can be installed in one float / float type float 8.

  The passing gates 1 and 1 ′ described above can be kept submerged in water at all times. Therefore, if the pollution control device is not necessary, it can be submerged and stored with other floats.
