置に戻す場合は、手動等により行えばよい。In the turning gate of the present invention, the turning means causes the door to turn from the first turning position to the second turning position due to the resistance of water flowing in the water passage when the water level of the water passage exceeds the automatic turning water level. Therefore, by setting the automatic turning water level to a water level capable of preventing flooding, it becomes possible to reliably prevent the occurrence of flooding. In addition, since the door is swung by the resistance of the water flowing in the water channel, there is no need for electrical detection, no equipment for electrically turning the door is required, and the equipment does not become large-scale and the cost is low. be able to. However, since the direction of the water flow flowing through the water channel is constant, the door is set in advance in the first turning position that blocks the drainage channel, and the door is set to turn to the second turning position in response to water resistance. In addition, when turning back to the first turning position after turning to the second turning position, it may be done manually or the like.

When the door 10 is located at the first turning position A, the plate-shaped member 22 projects toward the water channel 2 by the elastic biasing force of the coil spring 23 (including the water flow when the water level is higher than the reference water level). Further, in the plate-shaped member 22, the swirl region of the edge portion 22b is located outside the swirl region (indicated by the chain double-dashed line) in which the door 10 swivels, and the door 10 has the first swirl position A.
When the vehicle turns from and approaches the second turning position B, it comes into contact with the side surface 2b and rotates toward the upstream side of the water channel 2. Immediately before reaching the second turning position B, the door 10 turns around to the side opposite to the bearing 21. Specifically, the plate-shaped member 22 is formed such that the lower end 22c on the edge 22b side is formed lower and the lower end on the shaft 22a side is formed higher than that, and immediately before reaching the second turning position B, the edge 22b side is formed. It passes through the outside of the edge 12 of the door 10 and turns around to the opposite side when the shaft 22a side exceeds the upper edge of the door 10. In addition, D in FIG. 1 and FIG. 3 is a flat concrete bottom provided on the bottom surface of the irrigation canal 2. When this concrete bottom D is provided, the bottom surface of the irrigation canal 2 becomes uneven and the door 10 is The door 10 can be prevented from being hindered from opening and closing.
The opening and closing of can be stabilized.

じたままである。When the water level flowing through the irrigation canal 2 is in a normal state, the lower end of the plate member 22 is located at a position higher than a predetermined reference water level, so that even if the door 10 projects toward the irrigation canal 2 side. The plate-shaped member 22 receives no resistance from the water flow flowing through the irrigation channel 2, the edge 31a of the plate-shaped rubber 31 is engaged with the edge 12 of the door 10, and the door 10 is closed by the plate-shaped rubber 31. Up to.

A force for turning the vehicle from the first turning position A to the second turning position B is generated. Further, the force causes the plate-shaped rubber 31
Is bent and deformed in the corresponding turning direction of the door 10. Further, when the water level rises, both the turning force generated in the plate member 22 and the amount of bending deformation of the plate rubber 31 increase.

To rotate. Then, before the door 10 reaches the second turning position B, the edge 22b side passes outside the edge 12 of the door 10, and the shaft 22a side goes beyond the upper edge of the door 10 and turns around to the opposite side. After that, the door 10 moves to the second turning position B.
When it reaches, the edge 12 of the door 10 comes into contact with the door receiver 7 provided in the concave portion 6 of the side surface 2b, and the turning operation of the door 10 is stopped, whereby the door 10 is in the second turning position B. Become. In this state, the water that had flowed only through the irrigation channel 2 until then is blocked by the turning gate 1 and the drain pipe 3
It is possible to prevent the flood from flowing toward the river.

When the door 10 swivels in one direction around the shaft 11 arranged at the position C near the corner, the water channel 2 and the drain pipe 3
One side is closed, and when the door 10 turns in the opposite direction, the other side is closed. Further, since the plate-shaped member 22 receives the resistance of the flowing water flowing through the irrigation canal 2 to generate a force for turning the door 10 to the second turning position B side, the turning means 20 has a simple mechanism. Further, since the lower end height of the plate-shaped member 22 is provided so as to substantially match the reference water level, when the water volume reaches the reference water level, the lower end of the plate-shaped member 22 is soaked in water to receive resistance from running water. Like In addition, the plate-shaped member 22 that generates a force for turning the door 10 to the second turning position B side by receiving the resistance from the flowing water flowing through the irrigation channel 2 originally has a shaft 11 that is a turning center in order to generate a large force. Although the plate-shaped member 22 is provided at a position far from the
When the side surface 2b of the irrigation canal 2 is contacted when turning from the turning position A to the second turning position B, the force is applied from the side surface 2b to turn about the vertical axis, and the side opposite to the side where the door 10 is attached. Since it wraps around, it is possible to prevent the plate-shaped member 22 from being damaged.
