[0028] The sliding plate 3 is threadedly connected to the threaded rod 9 through an internal thread. In the initial state, the filter cartridge 6 is located directly below the annular brush 14. When the threaded rod 9 rotates, the sliding plate 3 is driven to move. The filter cartridge 6 moves upward and its surface contacts the inner bristles of the annular brush 14.

[0029] The one-way valve in the water suction pipe 155 is unidirectionally conductive toward the interior of the pressure chamber 151, and the one-way valve in the water spray pipe 156 is unidirectionally conductive toward the exterior of the pressure chamber 151.

[0034] A specific application of this embodiment is: when conducting water pollution detection, the motor A8 can be turned on to drive the threaded rod 9 to rotate so that the sliding plate 3 moves downward to the bottom end. When the sliding plate 3 moves downward to the bottom end, it will drive the bottom plate 5 to move downward to the target water area through the connecting rod 4, and the detection head 7 will detect the target water area. At this time, the filter cartridge 6 will prevent other debris from entering and contacting the detection head 7. After the detection is completed, the motor A8 can be turned on to drive the threaded rod 9 to rotate so that the sliding plate 3 moves upward. At this time, the filter cartridge 6 will move upward to the inner side of the annular brush 14, and the motor B12 can be turned on to drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 will drive the annular brush 14 to rotate through the connecting frame 13. The rotation of the annular brush 14 will clean the surface of the filter cartridge 6 with its inner bristles, so that the subsequent detection work will not be affected by the dirt adhered to the surface of the filter cartridge 6 during the previous detection work, thereby improving the accuracy of the detection. The rotation of the rotating shaft 11 will also drive the rotating gear 157 to rotate. At the beginning, the rotating gear 157 rotates and its teeth are engaged with the gear rod 154, which will drive the gear rod 154 moves to the right, the gear rod 154 moves to the right, which drives the piston rod 153 to move to the right, the return spring 152 is stretched, and the piston rod 153 moves to the right, which forms a negative pressure in the pressure chamber 151. At this time, the water in the water tank 158 is sucked into the pressure chamber 151 through the suction pipe 155. When the rotating gear 157 rotates to the point where the toothless part is out of mesh with the gear rod 154, the return spring 152 rebounds and drives the piston rod 153 to move to the left to restore. At this time, the piston rod 153 squeezes the water in the pressure chamber 151 so that it passes through the water spray pipe 156 is sprayed out, and the water sprayed from the water spray pipe 156 will spray to the inner side of the annular brush 14 to flush the filter cartridge 6 to prevent incomplete cleaning of the filter cartridge 6, and the collision block 165 will repeatedly squeeze the air bag 162 when rotating with the rotating shaft 11. The compressed air bag 162 will enter the air pressure chamber 161 to push the push rod 163 to move to the left. The push rod 163 moving to the left will drive the collision plate 164 to hit the filter cartridge 6, causing the filter cartridge 6 to vibrate slightly, shake off dirt, enhance the cleaning effect, and further improve the accuracy of subsequent detection.
