にくみ上げられるので一層起こり易くなる。Conventional technology For example, a dam provided for pumped storage power generation is configured as a double dam.For example, during the daytime, the water from the upper dam is used for power generation, and the used water is stored in the lower dam. This is pumped to the upper dam at night, and this water is used again for power generation. In such a case, if the water pumped up from the lower dam is polluted, the water in the upper dam will also become cloudy, which is not preferable. The pollution of the pumped water is more likely to occur when the amount of water in the dam below becomes smaller because the mud at the bottom is pumped up together with the water.
また、ダムの水を放流する場合にも、上記と同様にダム
の水量が少なくなると底の泥が排出されるので汚濁水が
放出されることになって好ましくない。Also, when the water from the dam is discharged, if the amount of water in the dam is reduced, the mud at the bottom is discharged and polluted water is discharged, which is not preferable.

取り付けたものが使用される。The water intake and drainage device A is provided with a fence surrounding area 2 surrounded by underwater fences 1, 1 ... In the water area.
That is, the underwater fence 1 prevents the flow of pollutant particles in the floating body 1a, but allows water to freely flow therethrough.
With these underwater fences 1, 1
.. are connected in an annular shape as shown in FIG. 2 to divide the water area, and the inflow of pollutant particles into this surrounding area 2 is prevented, and the pollutant particles within this area flow out of the area. Only clean water is allowed to freely flow in and out of this area. Although details of the water-passing flat body 1b are not shown in the drawings, for example, a net in which fibers such as hairs are rolled into a barrel shape to allow water to pass therethrough is attached in some places.

ス囲繞区域２内にとどめられ、外側に流出しないので、
その外側の水域にはよりきれいな水が排出される。When pumping water from the lower dam b, a pump (not shown) is operated to draw water from the intake / drainage device B to the intake / drainage device A. At this time, in the water intake and drainage device B, water is sucked into the fence surrounding area 2 ′ from the outside, but even if this water is polluted, the submerged fences 1 ′, 1 ′ ,. Only clean water is taken in and out 3'a
Is sucked into the flexible water conduit 3 ', and this water is drained from the intake / drain port 3a through the flexible water conduit 3 of the water intake / drainage device A. This drained water is clean water, but even if it contains pollutant particles, these particles are retained in the fence surrounding area 2 and do not flow out,
Cleaner water is discharged to the water area outside it.

して移動し、常にきれいな水を排出できる。In this way, the amount of water in dam b decreases,
When the water surface comes down, the water conduit 3'is flexible and has a sufficient length, so that the intake / drainage port 3'a moves following the decrease in the water surface, the same as in the previous case. So that it can be taken. Then, this water is discharged from the water intake / drainage device A, but since the water conduit 3 is flexible and has a sufficient length, the water intake / drainage port 3a also moves along with the rise of the water level, and is always Can discharge clean water.

However, even if the water intake / drainage device B is omitted and water is taken directly from the pipe 4, the water intake / drainage device A removes pollutant particles and only clean water is discharged to the outside of the fence surrounding area 2. The pollutant particles settle and accumulate at the bottom.

することができる。EFFECTS OF THE INVENTION According to the present invention, an area surrounded by an underwater fence is provided in the water area, and a flexible water conduit having an intake / exhaust port is provided in this area. Therefore, when the water surface of the water area is high, the water surface is low. Even so, the flexible water guide tube can follow this, so that the intake / drain port can always be located at the surface layer of the water area, so that water intake or drainage can always be performed with clean water. As a result, it is possible to prevent pollution of the water area during water intake or drainage.
