A front mesh plate 213 is provided at the end of the inner wall of the cylinder 11, and the front mesh plate 213 is vertically arranged with the side mesh plate 211, and the two long sides of the front mesh plate 213 are fixedly connected with the two connecting rods 212 at the corresponding positions, and the flat mesh plate 214 is horizontally arranged at the bottom end of the side mesh plate 211, and the flat mesh plate 214 is fitted with the lower side of the front mesh plate 213. The front mesh plate 213, the two side mesh plates 211, the flat mesh plate 214 and the corresponding positions of the inner wall of the cylinder 11 form an outer filter box 21. When the inner filter box 22 is moved out of the cylinder 11 for cleaning, the outer filter box 21 can filter the water entering from the water inlet 111 to reduce the impurities entering the convenient maintenance pump station.

[0022] Reference Figure 2-Figure 4 The opening of the inner filter box 22 faces the water inlet 111 in the cylinder 11, and the bottom wall of the inner filter box 22 is spaced apart from the water inlet 111 in the cylinder 11. The opening of the inner filter box 22 fits in with the corresponding position of the inner wall of the cylinder 11. The displacement member includes a rope 4, which is fixedly installed on the top of the inner filter box 22. The rope 4 is used to manually pull the inner filter box 22 out of the cylinder 11, so that the inner filter box 22 can be regularly pulled out of the convenient maintenance pump station for cleaning. Manual work does not need to frequently enter the convenient maintenance pump station to clean the filter screen. A vertical limiting groove 2121 is provided on the side of the connecting rod 212 near the inner filter box 22. A plurality of balls 23 are rotatably installed at the corresponding positions of the inner filter box 22 and the limiting groove 2121. The balls 23 are slidably connected to the limiting groove 2121 to reduce the friction force of the inner filter box 22 during vertical reciprocating movement.

[0023] Reference Figure 2-Figure 4 A support rod 24 is fixedly connected to the lower side of the two side mesh plates 211, and a guide slot 241 is opened on the opposite sides of the two support rods 24. The two side edges of the flat mesh plate 214 are slidably connected to the guide slots 241 at the corresponding positions, so that the flat mesh plate 214 can be disassembled, which is convenient for dredging and cleaning the flat mesh plate 214, and at the same time, it is convenient to dredge and clean the mesh plate 213 and the ends of the two side mesh plates 211 near the bottom.

[0024] Reference Figure 3-Figure 4A roller brush 3 is rotatably provided at the lower position of the side of the inner filter box 22 near the side mesh plate 211 and the main mesh plate 213. The long side direction of the roller brush 3 is perpendicular to the long side direction of the connecting rod 212. Multiple roller brushes 3 are in contact with the main mesh plate 213 or the side mesh plate 211 at corresponding positions. The inner filter box 22 is controlled to reciprocate vertically by a rope 4, and multiple roller brushes 3 clean and dredge the main mesh plate 213 or the side mesh plate 211 at corresponding positions.

[0025] The working principle of the embodiment of the present application is: when it is necessary to clean the filter screen at the water inlet 111 of the convenient maintenance pump station for water conservancy projects, the inner filter box 22 is manually pulled out to the outside of the convenient maintenance pump station for cleaning by rope 4, and at the same time, the outer filter box 21 can filter the water entering from the water inlet 111. After the inner filter box 22 is cleaned, the inner filter box 22 is sent into the outer filter box 21, and the inner filter box 22 can be controlled to move back and forth vertically by rope 4, and multiple roller brushes 3 are used to clean the positive screen plate 213 or the side screen at the corresponding position. The plate 211 is cleaned and unblocked. When the height of the debris accumulation on the flat mesh plate 214 exceeds the height of the gap between the bottom wall of the inner filter box 22 and the water inlet 111 in the cylinder 11, the opening of the inner filter box 22 and the water inlet 111 in the cylinder 11 are misaligned. The convenient maintenance pump station can be entered to clean and unblock the flat mesh plate 214, so that the inner filter box 22 can be pulled out of the convenient maintenance pump station for cleaning regularly. There is no need for manual labor to frequently enter the convenient maintenance pump station to clean the filter, which protects the health of the workers to a certain extent.
