[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Please see Figures 1-3 A water diversion device for water conservancy and hydropower includes a vertically arranged water diversion cylinder 1 with an open upper end. A cylinder cover 2 is detachably connected to the upper end of the water diversion cylinder 1. After opening the cylinder cover 2, the water diversion cylinder 1 can be cleaned, or other internal components of the water diversion cylinder 1 can be disassembled and cleaned. Several floats 4 are detachably connected at circumferential intervals at the bottom of the cylinder cover 2, located around the periphery of the water diversion cylinder 1. As the water diversion operation proceeds, the water diversion cylinder 1 can rise and fall with changes in water level to ensure the normal operation of the water diversion work. The water intake cylinder 1 has several first filter holes evenly distributed on its side, providing a large filtration area. A filter cylinder 3 is detachably connected between the bottom of the cylinder cover 2 and the inner bottom of the water intake cylinder 1. Several second filter holes are evenly distributed on the side of the filter cylinder 3, providing a large filtration area. This design allows the water intake cylinder 1 to be supported by a float 4, preventing it from directly contacting the mud and sand at the bottom of the water during the initial water intake, thus making it less likely for the first or second filter holes to become clogged. The diameter of the first filter hole is larger than that of the second filter hole, allowing for double filtration of the water during the water intake process. A water intake pipe 9 is fixedly connected to the cylinder cover 2, extending vertically into the filter cylinder 3. The water intake pipe 9 can be connected to an external water pump via a flexible hose. After the external water pump is started, the water is discharged after double filtration, reducing the risk of clogging the water pump or the pipe.

[0023] The water intake cylinder 1 is fixedly connected to several vertically arranged connecting rods 14 at its outer bottom, allowing a certain distance between the water intake cylinder 1 and the anti-sinking ring 15. When the anti-sinking ring 15 comes into contact with the bottom sediment, it also maintains a certain distance between the water intake cylinder 1 and the bottom sediment, thus preventing the bottom sediment from directly contacting the first filter hole. Anti-sinking rings 15 are fixedly connected to the lower ends of each connecting rod 14. When the water level is low, the anti-sinking rings 15 come into contact with the bottom sediment, preventing the lower end of the water intake cylinder 1 from inserting into the bottom sediment. A counterweight 16 is fixedly connected to the bottom of the anti-sinking ring 15 to increase weight. When the water level is too low to support the water intake cylinder 1 with the buoyancy of the float 4, the counterweight 16 helps keep the water intake cylinder 1 vertical. The counterweight 16 is tapered, wider at the top and narrower at the bottom, making it easy to insert into the bottom sediment.

[0024] Furthermore, the anti-sinking ring 15 is provided with several openings 18 spaced apart along the circumference, and the counterweight block 16 is provided with water passage holes 17 arranged in the vertical direction. The water passage holes 17 and openings 18 facilitate the flow of water, thereby making it easy to put the water inlet tube 1 into the water, and it will rise and fall with the water level under the action of buoyancy.

[0025] Specifically, a flange 8 is fixedly connected to the upper end of the water inlet cylinder 1, and a fixing bolt is fixedly connected between the flange 8 and the cylinder cover 2; the cylinder cover 2 is detachably connected to the water inlet cylinder 1 through the cooperation of the flange 8 and the fixing bolt. The flange connection method allows the cylinder cover 2 to be quickly removed, making the operation convenient.

[0026] In addition, a fixed shell 5 adapted to the float 4 is fixedly connected to the cover 2. The fixed shell 5 is a hollow hemispherical shape, and the upper part of the float 4 is located inside the fixed shell 5. A screw 6 passing through the fixed shell 5 in a vertical direction is fixedly connected to the upper end of the float 4. A nut 7 is threadedly connected to the upper end of the screw 6. The float 4 is detachably connected to the cover 2 through the cooperation of the fixed shell 5, the screw 6 and the nut 7. However, when it is necessary to replace a certain float 4, the nut 7 can be unscrewed to remove the float 4 from the fixed shell 5 for replacement.

[0027] Finally, the filter cylinder 3 is open at both the top and bottom. A first pressure ring 10 is fixedly connected to the lower end of the filter cylinder 3. A sealing ring 11 that fits against the water inlet cylinder 1 is fixedly connected to the bottom of the first pressure ring 10, which can seal the junction of the first pressure ring 10 and the water inlet cylinder 1. Several positioning holes 13 are spaced apart circumferentially on the first pressure ring 10. A positioning post 12 that passes through the positioning holes 13 vertically is fixedly connected to the inner bottom of the water inlet cylinder 1, which can position the first pressure ring 10 so that the filter cylinder 3 will not move radially. A second pressure ring is fixedly connected to the upper end of the filter cylinder 3. The structure of the second pressure ring is the same as that of the first pressure ring 10. The filter cylinder 3 can be sealed and positioned with the cover 2. The filter cylinder 3 is detachably connected between the water inlet cylinder 1 and the cover 2 through the cooperation of the first pressure ring 10, the sealing ring 11, the positioning post 12, the positioning hole 13 and the second pressure ring. After opening the cover 2, the filter cylinder 3 can be directly taken out from the water inlet cylinder 1 for cleaning. After cleaning, the filter cylinder 3 is put into the water inlet cylinder 1, and the position of the first pressure ring 10 is positioned by the cooperation of the positioning post 12 and the positioning hole 13. Then, the cover 2 is closed, which can squeeze the sealing ring 11 to seal the junction of the first pressure ring 10 and the water inlet cylinder 1 and the junction of the second pressure ring and the cover 2.

[0028] In use, first connect the water inlet pipe 9 to the inlet of the external water pump via a flexible hose. Then, place the water inlet cylinder 1 in the water. Under the action of the float 4, the water inlet cylinder 1 will be lifted into the water. Then, start the external water pump. The water enters the water inlet cylinder 1 after being filtered through the first filter hole, and then enters the filter cylinder 3 after being further filtered through the second filter hole. Finally, it is discharged through the water inlet pipe 9 and the external water pump. As the water level drops and the water inlet cylinder 1 moves downwards and approaches the bottom sediment, the counterweight 16 first inserts into the bottom sediment, and then the anti-sinking ring 15 contacts the surface of the bottom sediment. This keeps a certain distance between the water inlet cylinder 1 and the bottom sediment, making it difficult for the bottom sediment to directly contact the water inlet cylinder 1, thus preventing a large amount of sediment from entering the water inlet cylinder 1.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
