In addition, because the water filter dam cannot be moved and blocks the fish migration path, it will cause difficulty for fish to migrate. In addition, traditional water filter dams only rely on themselves to purify water quality and cannot handle sand in the water, causing sand to accumulate in front of the water filter dam, affecting the subsequent water quality of the water filter dam.

[0045] See Figure 5 , both the fixed filter box 2 and the mobile filter box 3 include:

[0046] The box body 4 has a receiving cavity inside, and the surface of the box body 4 is made of a mesh plate, which can allow water to pass through.

[0047] The multi-layer filter layer 5 is filled in the receiving cavity of the box body 4. In this embodiment, looking from the upstream to the downstream of the water flow direction, the multi-layer filter layer 5 is respectively: a gravel layer, a sandstone layer, a sand layer and an activated carbon layer. The upper surface of the box body 4 is detachably connected with a top plate 8, and after the top plate 8 is removed, the multi-layer filter layer 5 can be filled into the receiving cavity.

[0048] See Figure 2, and also includes a moving structure for moving the mobile filter box 3. The moving structure includes:

[0049] The movable seat 9 is installed at the lower end of the movable filter box 3;

[0050] The moving groove 10 is provided on the lower surface of the single section 1 for the moving seat 9 to move. The moving seat 9 is movably mounted in the moving groove 10 . The moving seat 9 can move relative to the moving groove 10 along the X direction.

[0051] A slide rail 12 is mounted on the upper surface of the moving groove 10;

[0052] The slider (not shown) is installed on the lower surface of the movable seat 9. The slider is movably clamped on the slide rail 12. The movable seat 9 and the movable filter box 3 can slide along the X direction as a whole by relying on the slider and the slide rail 12.

[0053] The equipment box (not shown) is installed on the lower surface of the single section 1 and is located on the upstream side of the filter dam along the X direction.

[0054] A driving cylinder (not shown) is installed in the equipment box at its non-telescopic end. The piston rod of the driving cylinder passes through the equipment box and is fixedly connected to the moving seat. The piston rod of the driving cylinder is along the X direction. When the piston rod of the driving cylinder is telescopic, the moving seat 9 and the moving filter box 3 can be moved as a whole along the X direction. Figure 1 , so that the mobile filter box 3 is staggered with the fixed filter boxes 2 on both sides, forming a channel for fish to migrate through, which can provide a way for fish to migrate during the fish migration period. Because the driving cylinder is in the water of a single section, the equipment box is used to ensure that the cylinder body of the driving cylinder does not contact the water.

[0055] See Figure 3 and Figure 4 , and further comprising two planting troughs 15, the two planting troughs 15 are arranged along the X direction, and the planting troughs 15 are opened on the lower surface of the single section 1, and the two planting troughs 15 are both located on the upstream side of the filter dam. Aquatic plants are planted in the planting troughs 15, ensuring that the upper end height of the aquatic plants is higher than the upper surface of the single section 1. The aquatic plants themselves can purify water quality and produce oxygen.

[0056] Viewed along the X direction, a sand discharge groove 16 is provided between the two planting grooves 15. A sand discharge plate 17 is provided in the sand discharge groove 16, and the sand discharge plate 17 can move along the Y direction, and the lower surface of the sand discharge plate 17 abuts against the lower surface of the sand discharge groove 16. The first cavity and the second cavity are respectively provided at both ends of the single section 1 along the Y direction, and a sand discharge cylinder 14 is installed in the first cavity, and the non-telescopic end of the sand discharge cylinder 14 is fixed in the first cavity, and the piston of the sand discharge cylinder extends out of the first cavity and is fixedly connected to the sand discharge plate 17, and the piston axis of the sand discharge cylinder 14 is along the Y direction. An inspection door is also installed on the single section 1, which is used to open the first cavity to inspect the sand discharge cylinder. Through the extension and retraction of the sand discharge cylinder 14, the sand discharge plate 17 moves along the Y direction, so that the sand discharge plate 17 can push the sand in the sand discharge groove 16 to move toward the second cavity.

[0057] A sand discharge port 18 is provided on the side wall of the second cavity along the Y direction. When the sand discharge plate 17 moves along the Y direction, the sand discharge plate 17 can push the sand in the sand discharge trough 16 from the sand discharge port 18 to the second cavity. Two sealing structures for closing the sand discharge port 18 are provided on the single section 1. In a top view, the center line of the sand discharge port 18 along the Y direction is defined as line M, and the surface passing through line M and along the vertical direction is defined as surface Z. The two sealing structures are symmetrically arranged along surface Z. The sealing structure includes:

[0058] The guide rod 19 is fixed on the single section 1, and the length direction of the guide rod 19 is along the X direction. The guide rod 19 is arranged on the inner wall of the second cavity.

[0059] The closing plate 20 is movably mounted on the guide rod 19 and can move relative to the guide rod 19 along the X direction. The two closing plates 20 move toward each other along the X direction. When the two closing plates 20 contact each other, the two closing plates 20 seal the sand discharge port 18 together.

[0060] The electric telescopic rod (not shown) has a non-telescopic end fixed to the inner wall of the second cavity, a telescopic end fixedly connected to the closing plate 20, and an axis of the electric telescopic rod along the X direction. The closing plate 20 moves along the X direction by moving the telescopic end of the electric telescopic rod along the X direction.

[0061] A collection box 21 is installed in the second cavity. The collection box 21 has no upper surface. The height of the upper end of the collection box 21 is lower than the height of the sand discharge port 18, ensuring that the sand and water in the sand discharge trough 16 can enter the collection box 21 from the sand discharge port 18. A sand discharge pipe is installed at the bottom end of the collection box 21. One end of the sand discharge pipe is connected to the interior of the collection box 21, and the other end of the sand discharge pipe passes through the second cavity. A cyclone sand remover 24 is installed at one end of the sand discharge pipe passing through the second cavity, and the inlet of the cyclone sand remover 24 is connected to the sand discharge pipe. A pump is installed on the sand discharge pipe. In this embodiment, it is a sand pump, which is used to pump sand and water into the cyclone sand remover 24. The water outlet of the cyclone sand remover 24 is connected to the single section 1 through a pipeline, and the water after sand removal can flow back into the water of the single section 1. The cyclone desander 24 is a prior art, which includes a conical cylinder. A mixture of water and sand enters the cyclone desander 24 from the side wall of the conical cylinder. Due to its high density, the sand continuously slows down in the conical cylinder and is finally discharged from the lower end of the conical cylinder, while the water with the sand removed is discharged from the top of the cyclone desander 24 and finally re-directed back to the water body of the single section 1 through a pipeline.

[0062] See Figure 1 A side slope 22 is arranged above the side wall of the single section 1 along the Y direction. The side slope 22 and the single section 1 together constitute a compound section. A plurality of protective bricks 23 are laid on the side surfaces of the side slope 22 and the single section 1 along the Y direction. In this embodiment, aquatic plants can be planted between the protective bricks 23, which reinforces the structure of the single section 1 and the side slope 22.

[0063] The usage process of this structure is:

[0064] When water containing sand flows in a single section, since the water containing sand first passes through the planting trough 15 on the upstream side, the aquatic plants planted in the upstream planting trough 15 will come into contact with the sand, thereby slowing down the sand and making it easier for the sand to settle in the sand discharge trough 16. A small amount of sand that passes through the sand discharge trough 16 is slowed down again by the planting trough 15 on the downstream side and intercepted on the upstream side of the filter dam.

[0065] After a period of time, the operator manually opens the electric telescopic rod to move the closing plate 20 to the two sides in the X direction, thereby opening the sand discharge port 18, and then manually opens the sand discharge cylinder 14 to drive the sand discharge plate 17 to push the sand and water into the central box 21 in the cavity, and then manually controls the sand discharge plate 17 to reset through the sand discharge cylinder 14.

[0066] The operator starts the pump at the same time to pump the sand and water in the concentration box 21 into the cyclone desander 24, and the water body after desandering returns to the water body of the single section 1.

[0067] When a path for fish migration is needed, the mobile filter box 3 is moved by driving the oil cylinder, so that the mobile filter box and the fixed filter box are staggered to form a channel for fish migration, thereby achieving the purpose of not affecting fish migration.

[0068] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
