The grabbing plate 550 is installed through the grabbing frame 57 installed in a lifting mode, when the grabbing frame 57 is in contact with the top of the filtering frame 40, grabbing pins 551 on the grabbing plate 550 are driven by the first magnet 555 and the second magnet 556 to be matched with grabbing grooves 41 on the filtering frame 40, grabbing and locking of the filtering frame 40 are achieved, and then lifting and locking are achieved through the matching locking assembly 44. In order to ensure that the filter frame 40 cannot rise automatically, a clamping block 430 with a right-angle structure is arranged in the guide frame 43 at the lower side, the clamping block 430 is driven to rotate when the filter frame 40 is pressed down, and the filter frame 40 is locked by a locking pin 431 on the clamping block 430, so that the filter frame 40 is prevented from rising automatically. The butt joint assembly 64 drives the butt joint 32 to be matched with the butt joint 641, the water pump 62, the telescopic rod 61 and the water pump head 60 are combined to carry out water pumping energy storage operation, and the purpose of the butt joint assembly 64 is to facilitate the butt joint of the telescopic rod 61 and the butt joint opening 641 with the branch pipes 31 at different positions, so that different filter frames 40 are cleaned. The screw 645 is driven to rotate by the docking motor 640, so that the moving disk 647 and the matching block 646 horizontally move, and the driving frame 644 deflects to drive the docking port 641 and the docking head 32 to dock with each other or separate from each other. The storage rack 70 in the blocking mechanism 7 is arranged obliquely downwards, after the swinging rack 74 rotates to a position perpendicular to the storage rack 70, the wind-up roller 72 is released, the counterweight rod 73 moves downwards along the guide groove 75, so that an inclined blocking surface is formed, when water flows down, water flows downwards along the filter rack 40 and the filter screen 42, the washed impurities enter the sewage outlet 21 through a space formed by the subsequently lifted filter rack 40, and are cleaned out along the sewage cleaning groove 11, so that the cleaning effect is ensured.
