[0025] Beneficial effects:

[0026] 1. By controlling the rotation of the stirring frame, the sliding box is rotated to be directly above the stirring frame, the crane on the left side lifts the telescopic frame and other structures integrated with the telescopic frame, and the telescopic frame moves downwards along the inner wall of the left side of the pool; when the left side control rod is in contact with the upper slope surface of the corresponding control block, the control rod continues to move downwards, and under the action of the slope surface, the left side control rod moves rightwards to drive the rotating frame to rotate, the rotating frame drives the connecting rod, the moving block and the two push rods to move, the two push rods drive the two fixed blocks to move, the part of the two fixed blocks beyond the connecting box enters the connecting box, the crane continues to move downwards until the bottom of the connecting box is in contact with the inner wall of the bottom of the sliding box, then the rotation of the stirring frame drives the control rod to rotate, and the control rod is separated from the control block; under the action of the two compression springs and the torsion spring, the control rod and the two fixed blocks return to the original positions, the sides away from each other of the two fixed blocks are connected with the inner wall of the fixed hole on the connecting box, and the connecting box and the sliding box are connected together.

[0027] 2. The rotation of the stirring frame drives the left scraper to rotate, cleaning the sludge from the inner left wall of the pool. When the left control lever touches the corresponding control block again, the motor starts, driving the power gear to rotate, which in turn drives the driven gear. Through the meshing of the driven gear and rack, the connecting box moves to the right, allowing the brush to rotate and move to the right within the pool. Simultaneously, the brush can move back and forth left and right under the action of the actuating block. When the connecting box moves to the far right of the pool, the right control lever touches the slope of the control block, at which point the motor stops. When the connecting box stops moving to the right, the stirring frame continues to rotate. The control lever leaves the slope of the control block. After the stirring frame rotates one revolution, the control lever touches the control block again. When the control lever passes the slope on the control block, the stirring frame stops rotating. The stirring frame rotates one revolution, driving the scraper on the right side to clean the sludge on the inner wall of the right side of the pool. At this time, the brush cleans the sludge on the inner wall of the front, bottom and rear sides of the pool. When the connecting box moves, it also drives the electric brush to move, so that the electric brush contacts the stirring frame and cleans the sludge next to the air holes with the filter screen on the stirring frame.

[0028] 3. When the mixing frame stops rotating, the top of the telescopic frame is hung on the crane. The control lever on the right moves to the left under the action of the control block on the right, causing the rotating frame to rotate. The rotation of the rotating frame causes the connecting rod, the moving block and the two push rods to move. The movement of the two push rods causes the two fixed blocks to move, so that the two fixed blocks separate from the corresponding fixed holes, allowing the connecting box and the sliding box to separate. Start the crane to lift the telescopic frame and other structures integrated with the telescopic frame out of the pool.

[0029] In this invention, the mixing frame and the moving mechanism work together to allow the scraper, brush, and electric brush to clean the sludge in the tank and at the air holes with filter screens on the mixing frame, thus preventing the air holes from being blocked and affecting the air output effect, which in turn affects the treatment of sewage.
