る。2. Description of the Related Art Sluice gates, which are installed at appropriate positions in water passages of water supply and sewerage facilities and rivers, are operated to open and close the water gates in order to adjust the amount of water flowing through these passages as necessary. And as a device for opening and closing the sluice gate,
Conventionally, as a mechanical type, a wire rope winch type or a trapezoidal tooth-shaped rack is erected on the upper end of the sluice gate, and a pinion is arranged so as to be meshable with this rack, and the pinion is passed through a transmission shaft. A rack type with a structure in which a handle that is manually operated or a drive motor with a speed reducer that is automatically operated by an appropriate control device is interlockingly connected, and a spindle with a screw threaded at the upper end of the sluice door.

まうといった構造的な欠点がある。However, although the wire rope winch type described above has an advantage in that it can cope with a large opening / closing load of the sluice gate or a long lift of the sluice gate for opening / closing, After the sluice gate reaches the bottom of the channel, it cannot be pushed further down, and the watertightness is weakened.As the sluice gate is repeatedly opened and closed, the rope stretches unevenly. As a result, there are structural defects such as a difference in the ascending / descending distance between one side and the other side of the sluice gate, and the inclination of the sluice door.

昇降させるため、昇降速度が遅く作業に時間がかかると
いった問題がある。In the rack type, the cost of manufacturing a long rack is high and the pinion mechanism is complicated. Therefore, when this rack type is used for a small floodgate, the device becomes disproportionately large and expensive. Become. Moreover, since the pinion is rotated to raise and lower, there is a problem that the raising and lowering speed is slow and the work takes time.

事故が生じる危険性もある。In the spindle type, the turning force involved in the opening / closing operation is transmitted through a large number of gear trains, and only one pitch of the screw is provided during one rotation of the spindle on which the screw is screwed. Since it does not move up and down, the lifting speed is slower, and sudden opening and closing cannot be done in an emergency.
Further, when the spindle is installed upright on the upper ends of a plurality of sluices, it is impossible to suspend the sluices in a horizontal state due to a manufacturing error of the screws. Further, if the opening / closing operation of the sluice door is repeatedly executed, the screw may be worn, which may cause an accident such as dropping of the sluice door.

るものであった。On the other hand, the hydraulic cylinder type has an advantage that the opening / closing speed can be arbitrarily set and can cope with a large opening / closing load, but an oil leak is inevitable in the hydraulic cylinder. Especially, when the sluice door is in the upper position and in the open state, there is a risk that the piston rod directly coupled to the sluice door may protrude more than necessary and the sluice door may slip down. And
In order to prevent such an accident, there is a problem in that even after the switchgear is installed, sufficient maintenance must be performed to detect and prevent oil leaks. Also,
In the hydraulic cylinder wire rope type, both the problems of the hydraulic cylinder type and the wire rope type are included.

れ以上は繰り出されなくなる。With the structure of the inventions of claims (1) and (2), when the open water gate is closed, the braking force of the brake-equipped drive motor is slightly released. To do. Then,
The dead weight of the sluice door overcomes the braking force of the drive motor with a brake, and only the own weight of the sluice door, which is offset by the braking force, acts on the means for opening and closing the sluice door with the chain structure. .
Therefore, in the water gate door opening / closing force imparting means of the chain row structure, the meshing partner with the sprocket is one after another from the power transfer means near the front end to the power transfer means near the rear end. It is fed vertically downward from the housing while passing through the row moving groove. As a result, the sluice gate also descends vertically downward in conjunction with the operation of the sluice gate opening / closing force applying means of the chain row structure. When the descent is performed for a certain period of time, the sluice door bottoms on the water channel bottom and is supported by the water channel bottom, so that the weight of the sluice door does not act on the opening / closing force applying means of the chain gate structure. As a result, the opening / closing force applying means for the water gate of the chain row structure cannot be further extended from the housing.

水路の遮断を解除する開操作が完了する。The turning force is transmitted from the power transfer means to the plurality of chain members face-to-face connected by the power transfer means in the direction of pushing the other side tangentially. For this reason, the plurality of chain members pass the traction force passively, and the traction force is transmitted to the other chain members adjacent to the plurality of chain members one after another, so that the water of the chain row structure is formed. The gate opening / closing force applying means has a traction force. Then, the means for applying the opening / closing force of the lock gate of the chain row structure is
The traction force that overcomes the weight of the sluice door and is reduced by the gravitational weight ultimately causes the opening / closing force imparting means for the sluice gate of the chain-row structure to be internal, and to the sluice door via the opening / closing force transfer member. The traction force is transmitted. As a result, in the same manner as described above, the opening / closing force applying means for the chain gate structure of the floodgate door is pulled vertically to the housing side, and the floodgate door also moves vertically upward in conjunction with it. When such movement is executed for a predetermined time, the sluice door is raised to a predetermined position and the opening operation for releasing the blockage of the water channel is completed.

に水門扉を開閉なさしめることができるものである。Since the present invention is constructed as described in detail above, it exhibits the following excellent effects. An open / close power transmission mechanism that converts the rotational force generated by a drive motor with a brake whose rotation speed can be arbitrarily adjusted into pressing force or traction force, and its length can be freely changed. It bends to the side where the sprocket is located only when pressure or traction force is passed, and in a state like a rod body, in conjunction with the operation of the opening / closing power transmission mechanism,
Since the water gate opening / closing device has a water gate opening / closing mechanism having a structure of transmitting passive pressing force or traction force to the water gate of a tagger structure or the like, the opening / closing speed can be freely changed. In particular, it is possible to deal with an emergency situation in which the sluice gate must be closed suddenly, and it is possible to perform a complete opening / closing operation regardless of the lifting stroke. In addition, since a hydraulic cylinder is not used as the power source for opening and closing, oil leakage does not occur, maintenance work can be done with ease, and the sluice door does not tilt during the opening and closing operation, so it is always in a horizontal state. It can be lifted and lowered. Further, in order to transmit and act the pressing force or the traction force on the sluice gate, unlike the spindle type, it does not depend on the rotation of the screw, so that a quick opening / closing operation can be performed and frequent opening / closing operations can be performed. However, no abrasion occurs and no accident occurs during the opening / closing operation. Furthermore, from the above, the sluice door opening / closing device according to the present invention has all the advantages of the conventional sluice gate opening / closing device, while eliminating all the drawbacks of the conventional sluice door opening / closing device. The sluice gate can be opened and closed smoothly at any time under any installation condition or under any circumstances.
