The spring structure has a shock-absorbing and buffering effect to improve the stability of the components. The bearing plate slides on the surface of the cylindrical rod to increase the cleaning range and improve the cleaning effect. A conical block is arranged at the bottom of the bearing plate. Through the conical structure design, the surface structure of the sludge on the bottom of the pool is destroyed during rotation to avoid the reduction of the dredging effect due to the smooth surface of the sludge. Secondly, the conical structure destroys the hard materials to improve the dredging effect. A spring block is arranged between the first circular block and the second circular block to achieve the shock-absorbing and buffering effect, protect the bearing plate, reduce component collision, reduce component wear, and prevent damage to the equipment due to excessive collision. The silicone block is made of silicone material, which has a certain buffering effect, has good wear resistance, enhances the buffering effect, and improves the protection effect on the equipment.

[0021] 4. The center-drive scraper is designed with a bearing mechanism that wraps the bottom of the center shaft with a bearing block to reduce external wear on components and maintain normal operation of the equipment. The support rod is connected to a metal ring, which has a buffering effect when the center shaft is placed on the bottom of the pool, reducing component collisions and maintaining normal operation of the equipment.

[0022] 5. The center transmission scraper is designed with a stabilizing mechanism. When there is water in the pool, the stabilizing plate is controlled by an electric push rod to fit the water surface, so as to reduce air turbulence, inhibit changes in water surface tension, reduce water surface fluctuations, prevent affecting the dredging effect, and reduce the silt scattered during operation. When there is no water in the pool, the stabilizing plate has a shielding effect to prevent the silt from scattering when scraping, reducing the difficulty of operation. By opening strip grooves, the contact area with the water surface is increased, the stabilizing effect on the water surface tension is improved, the stability of the components during operation is maintained, and work efficiency is improved. By opening circular holes and grooving, the fluid permeability is improved and the resistance of water flow to components is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

When there is water in the pool, the stabilizing mechanism 2 maintains the water surface tension, reduces the effect of water surface fluctuation, and avoids the water flow turbulence during operation that affects the operation effect. Secondly, it reduces the sludge from scattering and increases the difficulty of operation. When there is no water in the pool, it plays a role in shielding the sludge, and avoids the sludge from being scattered when the composite mechanism 1 scrapes the sludge, which increases the difficulty of operation. The stabilizing mechanism 2 is prone to retain a large amount of impurities when maintaining the sewage surface stable and shielding the sludge. Therefore, the cleaning mechanism 3 is used to rub the bottom of the stabilizing mechanism 2 to achieve the function of cleaning the parts, prevent the sludge from corroding the equipment, and extend the service life of the equipment.
