[0025] When the device is used to filter sundries in the river, the fixed frame 100 is installed at the required position, at this time, the intercepting net 200 will intercept the sundries in the river, and the sundries will be retained on the side where the brushes 340 are installed.

[0026] When the sundries intercepted by the intercepting net 200 need to be cleaned, the first motor 380 is started to run by the controller, the output shaft of the first motor 380 drives the round roller 330 to rotate counterclockwise, the round roller 330 drives the brushes 340 to rotate, the bristles of the brushes 340 come into contact with the surface of the intercepting net 200, and the sundries intercepted on the surface of the intercepting net 200 are cleaned, and the bristles of the brushes 340 can be deformed.

[0027] As shown in the drawings, Figure 1 and Figure 2 The driving assembly 310 comprises a second motor 311 fixedly connected to the top end of the fixed frame 100, the inner wall of the fixed frame 100 is rotatably connected with a lead screw 312, the surface of the lead screw 312 is threadedly connected with a sliding rod 313, one side of the sliding rod 313 penetrates out of the fixed frame 100 and is fixedly connected with one side of the moving frame 320.

[0028] The fixed frame 100 is provided with a limiting groove matched with the sliding rod 313, the surface of the sliding rod 313 is in sliding connection with the inner wall of the limiting groove, the second motor 311 is a servo motor, when it is needed to move the moving frame 320 upward, the second motor 311 is driven by the controller to drive the lead screw 312 to rotate clockwise, at this time, the sliding rod 313 will drive the moving frame 320 to move downward, when the moving frame 320 cannot continue to move upward, the second motor 311 is driven by the controller to drive the lead screw 312 to rotate counterclockwise, at this time, the sliding rod 313 will drive the moving frame 320 to move downward.

[0029] As shown in Figure 2 , Figure 3 and Figure 4 , the top end of the moving frame 320 is fixedly connected with a protective plate 322, the surface of the protective plate 322 is curved into an arc shape.

[0030] In the process of rotating, the bristles of the brush 340 are not in contact with the inner surface of the protective plate 322, and the other end of the protective plate 322 is away from the intercepting net 200.

[0031] As shown in Figure 5 , the bottom end of the collecting frame 350 is embeddedly installed with a filter plate 351, the middle part of the filter plate 351 is protruded in a "^" shape.

[0032] The filter hole diameter of the filter plate 351 is smaller than the mesh hole diameter of the intercepting net 200, when the moving frame 320 drives the collecting frame 350 to move upward, the water solution entering the collecting frame 350 will be discharged through the filter plate 351, and the filter plate 351 will intercept the collected sundries in the collecting frame 350.

[0033] As shown in Figure 4 , a plurality of cleaning rods 370 are arranged in an inclined manner, the other end of the cleaning rod 370 is in a conical shape. In the process of rotating, the end part of the cleaning rod 370 in a conical shape is better inserted into the bristles of the brush 340.

[0035] When the collecting frame 350 is installed on the inner side of the moving frame 320, the sliding plate 352 enters the sliding groove 321 and pushes the collecting frame 350 to move horizontally, at this time, the collecting frame 350 will enter the inner side of the moving frame 320, the sliding plate 352 is clamped in the sliding groove 321, after the collecting frame 350 is installed with the moving frame 320, the collecting frame 350 and the moving frame 320 are fixed by using bolts.

The protective frame 390 is used for protecting the first motor 380, so as to ensure the stability of the first motor 380 during operation.

[0037] It should be noted that after the plurality of brushes 340 are moved upward to complete the cleaning of the interception net 200, the driving assembly 310 is used to drive the moving frame 320 to move downward to the initial position, and in the process of moving the moving frame 320 downward, the first motor 380 is in the closed state.

[0038] In use, when the sundries intercepted by the interception net 200 are cleaned, the controller is started to drive the first motor 380 to drive the circular roller 330 to rotate counterclockwise, so that the circular roller 330 drives the plurality of brushes 340 to rotate to clean the surface of the interception net 200. The plurality of brushes 340 continue to rotate after cleaning the surface of the interception net 200 in the rotating process, and enter the inner side of the moving frame 320. At this time, the plurality of cleaning rods 370 are inserted into the bristles of the brushes 340 in the process of the brushes 340 continuing to rotate in the inner side of the moving frame 320. The brushes 340 continue to rotate, and the sundries on the bristles fall into the collecting frame 350 under the action of the cleaning rods 370. In addition, the bristles of the brushes 340 are deformed under the action of the mounting rod 360 when the bristles pass through the mounting rod 360, and the bristles continue to rotate by adhering to the surface of the mounting rod 360. At this time, the mounting rod 360 re-removes the sundries attached to the bristles. In the cleaning process, the driving assembly 310 is started to operate, so that the moving frame 320 drives the plurality of brushes 340 to move upward synchronously in the rotating cleaning process through the circular roller 330, so as to complete the comprehensive cleaning of the interception net 200. When the moving frame 320 cannot continue to move upward, the first motor 380 and the second motor 311 are closed. At this time, the staff releases the installation of the collecting frame 350 and the moving frame 320, and pulls the collecting frame 350 to move horizontally and separate from the moving frame 320. At this time, the staff can clean the sundries collected in the collecting frame 350.
