[0022] Auxiliary sliding bars 7 are slidably arranged on both sides of the surface of the bag net 65, and the auxiliary sliding bars 7 are fixed to the surface of the dam 1. In this embodiment, the auxiliary sliding bars 7 are arranged to provide a limit for the lifting and lowering of the bag net 65, thereby improving the stability of the bag net 65 when it is lifted and lowered.

[0023] The transmission mechanism 9 includes a waterwheel 91 that rotates in the inner cavity of the conical tube 8, and a first transmission rod 92 is fixed to the surface of the waterwheel 91. The other end of the first transmission rod 92 is provided with a second transmission rod 93 through a bevel gear transmission, and the other end of the second transmission rod 93 is provided with a third transmission rod 94 through a bevel gear transmission. The cleaning mechanism 10 is transmitted to the other end of the third transmission rod 94, and the first transmission rod 92, the second transmission rod 93 and the third transmission rod 94 rotate in the groove of the inner cavity of the dam 1. In this embodiment, through the arrangement of the waterwheel 91, the first transmission rod 92, the second transmission rod 93 and the third transmission rod 94, when the water flows through the conical tube 8, the water flow can be accelerated under the shape of the conical tube 8, and then hit the waterwheel 91, so that the waterwheel 91 rotates, and then under the transmission of the first transmission rod 92, the second transmission rod 93 and the third transmission rod 94, the cleaning mechanism 10 works.

[0024] The cleaning mechanism 10 includes a second threaded rod 101 transmitted by bevel gears and a third transmission rod 94, a cleaning rod 102 is meshed on the surface of the second threaded rod 101, a limiting rod 103 is slidably provided on the other end of the cleaning rod 102, and the limiting rod 103 is fixed to one side of the surface of the dam 1.

When the water flows through the drain 3, part of the water can enter the conical tube 8, and then under the action of the shape of the conical tube 8, the water wheel 91 starts to rotate, and under the action of the first transmission rod 92, the second transmission rod 93 and the third transmission rod 94, the second threaded rod 101 rotates, and further the cleaning rod 102 reciprocates on the surface of the mesh plate 5, which can clean the debris on the surface of the mesh plate 5 to prevent the debris from accumulating on the surface of the mesh plate 5. In addition, during the flood discharge stage, since the water surface is above the drain 3 and the bag net 65, under the action of the water flow, the suspended matter near the mesh plate 5 will follow the water flow to flow toward the mesh plate 5, and then under the action of the bag net 65, such suspended matter can be shielded, thereby preventing the suspended matter from gathering on the surface of the mesh plate 5. In addition, under the action of the flood discharge, after the water surface is lower than the bag net 65, the staff can use the motor 61, and under the action of the bevel gear group 62, the first threaded rod 63 and the meshing block 64, the bag net 65 moves upward, thereby facilitating the staff to clean the suspended matter in the bag net 65.
