Specifically, the bottom wall of the aeration plate is provided with bristles, and when the shovel plate moves below the aeration plate, the bristles are in contact with the top wall of the shovel plate.
Specifically, a piston is fixedly mounted at the bottom end of the air inlet pipe, the piston is in sliding fit with the connecting cylinder, a connecting pipe is arranged in an inner cavity of the connecting cylinder, the top end of the connecting pipe is fixedly connected with the bottom wall of the piston, the bottom end of the connecting pipe is fixedly connected with the top wall of the aeration plate, a through hole is formed in the piston, the top end of the connecting pipe is communicated with the air inlet pipe through the through hole, and the bottom end of the connecting pipe is communicated with the inner cavity of the aeration head.
The working principle of the invention is as follows: the air is input into the connecting cylinder 5 through the air inlet pipe 6, the air is discharged through the aeration plate 3, so that aeration is performed, when more dirt is deposited on the bottom wall of the aeration tank 1, the shovel plate 2 is driven by the driving mechanism to move relative to the inner wall of the bottom of the aeration tank 1, the dirt on the inner wall of the bottom of the aeration tank 1 is shoveled, the dirt flows away along with water flow, so that the inner wall of the bottom of the aeration tank 1 is cleaned, when the shovel plate 2 moves to be in contact with the aeration plate 3, the aeration plate 3 is gradually pushed upwards, so that the shovel plate 2 can pass through the lower part of the aeration plate 3, the aeration plate 3 is always positioned at the bottom of the inner cavity of the aeration tank 1 during aeration, so that the contact area between the air and sewage is increased, the aeration plate 3 moves upwards during cleaning, so that the aeration plate 3 is prevented from obstructing the movement of the shovel plate 2, the bottom wall of the aeration tank 1 can be cleaned conveniently and the dirt in the aeration tank 1 is prevented from being attached to the bottom wall of the aeration tank 1, and subsequent manual cleaning is easier; when the aeration tank 1 is cleaned, part of dirt may be adsorbed on the top wall of the shovel plate 2, when the shovel plate 2 moves below the aeration plate 3, the brush 7 contacts with the top wall of the shovel plate 2, so that the top wall of the shovel plate 2 is cleaned, and the friction force generated when the shovel plate 2 moves relative to the aeration plate 3 can be reduced through the roller 13; when the shovel plate 2 is driven to move, the motor 17 is started, the output end of the motor 17 drives the screw 16 to rotate, the screw 16 drives the sliding seat 18 to move on the sliding rail 15 when rotating, the sliding seat 18 drives the push rod 19 to move when moving, and the push rod 19 drives the shovel plate 2 to move when moving; when the aeration plate 3 moves upwards, the aeration plate 3 drives the connecting cylinder 5 to move upwards, so that the piston 8 moves downwards relative to the connecting cylinder 5, water at the bottom of the inner cavity of the connecting cylinder 5 is pressed into the shunt tubes 11 through the communicating pipes 14 and is sprayed out through the nozzles 12, water flow impacts on the bristles 7, and therefore the bristles 7 are cleaned, and more dirt is prevented from being adsorbed on the bristles 7; some impurities with higher density, such as small stones and the like, may not move along with the water flow but move along with the shovel plate 2, when the shovel plate 2 moves to be close to the impurity groove 20, the push rod 19 pushes the push plate 24 to move rightwards, so that the connecting rod 23 pushes the sealing cover 21 to move rightwards, the sealing cover 21 is opened, and the shovel plate 2 gradually pushes the impurities into the impurity groove 20, so as to collect the impurities; when the scraper moves rightwards, the scraper drives the connecting column to move synchronously, the connecting column moves relative to the installation barrel when moving, so that water inside the installation barrel is sprayed out from the spray head through a liquid conveying pipe, liquid flow impacts on impurities pushed by the scraper, the impurities are flushed into the impurity groove 20, the impurities are quickly collected, a rated air pressure value is set by the air pressure in the adjustable moving rod and the sealing pipe, when the air pressure in the aeration tank is too high, the moving rod drives the fixing ring to move inwards, the cam can be matched with the ejector rod at the moment, the ejector rod jacks up the top opening sealing block, the air is discharged from the air vent hole, the air pressure in the aeration tank is reduced, when the air pressure in the aeration tank is lower than the rated value, the moving rod moves outwards to return to be matched with the cam, the cam idles, the sealing block cannot be opened, the sealing performance of the aeration tank under the ground is kept, the aeration tank buried under the ground is prevented from being damaged due to overhigh air pressure generated by aeration, and the phenomenon that the excessive impurities in the aeration tank are always communicated with the outside to cause device fault is prevented.
