Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber gate operating device. More specifically, the present invention relates to a device for discharging the liquefied water that liquefies the moisture in the air supplied to and exhausted from the bag body and accumulates in the supply / exhaust pipe in the undulating weir made of rubberized cloth to prevent contraction during falling.

[0002]

2. Description of the Related Art Conventionally, a supply / exhaust pipe has been extended into a pit at the lower part of an operation room where the collected water is sucked up by a pump and discharged outside the operation room. In this case, since the dike is deeply divided to construct the air supply / exhaust pipe to the lower part of the operation room, a large amount of cost is required for the pit construction, and the dike is excavated to weaken the dike.

[0003]

In the undulating weir made of rubberized cloth, the water in the air supplied to and exhausted from the bag body is liquefied and collected in the supply / exhaust pipe to prevent the contraction at the time of falling, so the liquefied water is discharged. Although a device has been conventionally installed, in this case, the dike is deeply divided to extend the water supply / exhaust pipe to the lower part of the operation room, so it costs a lot to construct the pit. Has the drawback of weakening.

An object of the present invention is to provide a system in which no bit is provided so as to reduce the construction cost and maintain the levee, and to completely collect drain water and completely collapse the rubber gate.

First, the first embodiment shown in FIG. 1 will be described. A plurality of vent holes are provided on the side surface and the lower surface of the rubber gate 1, the vent holes are communicated with each other to provide a supply / exhaust pipe 2, and a drain tank 3 is provided below the supply / exhaust pipe 2. If this supply / exhaust pipe is provided with a slight gradient on the drain tank 3 side, liquefied water can be easily collected in the drain tank 3. A communication pipe 9 is provided in the drain tank 3, a drain recovery tank 16 is provided in communication with the communication pipe 9, and the pump 5 is connected to an upper surface of the drain recovery tank 16. The pump 5 is
It has two functions, a blower and a vacuum pump. The supply / exhaust pipe 2 is connected to a pump 5 via a three-way ball valve 4. The other side of the three-way ball valve 4 communicates with the discharge port 7. Pump 5 is 3
It communicates with the suction silencer 8 via the one-way ball valve 6.
The other side of the three-way ball valve 6 communicates with the communication pipe 9.

When used as a blower, as shown in FIG. 3, the three-way ball valve 4 is opened to communicate with the air supply / exhaust pipe 2. Further, the pump 5 and the suction silencer 8 are communicated with each other via the three-way ball valve 6, and the communication pipe 9 side is closed. In such a state, when the pump 5 is rotated, air is blown as a blower, and air is taken in from the suction silencer 8 and passes through the 3-way ball valve 6, the pump 5, the 3-way ball valve 4, and the supply / exhaust pipe 2. Air is sent to the rubber gate 1 and the rubber gate 1 stands up. A water sealing tube 10 is provided as a pressure safety device, and the water sealing tube 10 holds a predetermined air pressure. In addition, the automatic lodging is a float device 11
Do it by hand.

When recovering the water in the drain tank 3,
As shown in FIG. 3, the drain recovery tank 16 is decompressed by the pump 5 and the water in the drain tank 3 is sucked up into the drain recovery tank 16. At this time, the pump 5 and the discharge port 7 are communicated with each other through the three-way ball valve 4, and the supply / exhaust pipe 2 side is closed. Further, the pump 5 and the communication pipe 9 are communicated with each other via the three-way ball valve 6, and the suction silencer 8 side is closed. Conveniently, the capacity of the drain recovery tank 16 is larger than that of the drain tank 3. Further, the drain recovery tank 16 includes a drain pipe valve 17, a drain pipe 18, and a plastic scale plate 1.
Equipped with 9. When the prime mover is rotated in such a state, the pump 5 becomes a vacuum pump, the drain recovery tank 16 and the communication pipe 9 become vacuum, and the water in the drain tank 3 rises to the drain recovery tank 16, Collects in the drain recovery tank 16. When the rise of water stopped by the scale plate 19, the drain water was completely sucked up, so the prime mover was stopped and the drain pipe valve 17 was opened to release the water.

In the operation of collecting water in the drain tank 3, even after the drain water is completely sucked up, if the pump 5 is rotated, the pump 5 acts as a vacuum pump to suck up the air in the rubber gate and perform forced fall. You can

The second embodiment shown in FIG. 2 is a case in which the water in the drain tank 3 is atomized to be sucked up and collected. This device is particularly suitable when the lift between the drain tank 3 and the vacuum pump is large, for example, 7 m to 30 m. In the configuration of the second embodiment, the air supply pipe 20 is arranged in the middle of the communication pipe 9 of the first embodiment. The air supply pipe 2
The 0 is equipped with an air control valve 21 at its end.
When the air control valve 21 is provided in this manner, the adjustment is easy. Although the drain recovery tank 16 is omitted in the second embodiment as shown in FIG. 2, the drain recovery tank 16 may be provided.

Drain recovery in the second embodiment is performed as follows. When the pump 5 is operated as a vacuum pump, first, the water in the drain tank 3 is sucked up through the communication pipe 9. Since the air supply pipe 20 is arranged in the middle of the communication pipe 9, air is supplied from the air supply pipe 20. The air amount is adjusted by the air adjusting valve 21. When the air is replenished, the drain is atomized and sucked up, and is discharged from the discharge port 7 through the three-way ball valve 6, the pump 5, and the three-way ball valve 4. Check the drain collection condition by visual inspection. If the mist-like discharge state disappears, drain collection is complete, so stop the prime mover.

In the operation of collecting water in the drain tank 3 of the second embodiment, if the pump 5 is rotated even after the drain water is completely sucked up, the pump 5 serves as a vacuum pump and the air in the rubber gate 1 is removed. The gas is exhausted from the air supply / exhaust pipe 2 through the drain tank 3, the communication pipe 9, and the pump 5 to the discharge port 7, so that forced collapse can be performed.

The internal pressure of the rubber gate is generally low, and the discharge due to the contraction of the rubber gate becomes close to zero as the water level at the time of falling falls, inducing a notch phenomenon, etc., and the side wall portions at both ends do not fall completely in many cases. In this case, by operating the pump 5 as a vacuum pump for sucking up the drain as described above, the rubber gate can be completely collapsed, the river weir can be effectively held, and the communication of flood can be achieved. If a vacuum safety valve 14 is installed as a safety device in the case of forced laying, the pump and the prime mover will not be hindered even if the pump 5 is completely laid down and the pump 5 rotates. If the filter 15 is installed, the dust inside the rubber gate 1 is removed to protect the pump 5 and
At the time of drain collection, water is prevented from entering the pump 5 all at once for some reason. Further, by laying the supply / exhaust pipe 2 along the slope surface of the dike, it is not necessary to divide the dike deeply in order to extend the supply / exhaust pipe to the lower part of the operation room, which is required for pit construction. It does n’t cost a lot,
Also, excavation of the dike does not weaken the dike.
