[0028] like Figure 1-Figure 3 As shown, the auxiliary silt removal part can float up vertically, and a silt scraper is fixedly connected to the inner wall of the well body 1. The silt contact surface 4 can slide with the floating to abut against the silt scraper, and the silt scraper includes an outer ring 5 and an inner ring 6. A plurality of silt scraper rods 7 are fixedly connected between the outer ring 5 and the inner ring 6 by welding. The cross-sectional shape along the width direction of the silt scraper rod 7 is set to be a rhombus, and the acute angle of the rhombus is at the top and bottom of the silt scraper rod 7. A through groove 8 is arranged between two adjacent silt scraper rods 7. During the floating of the auxiliary silt removal part, the solid impurities deposited on the silt contact surface 4 will be driven to abut against the silt scraper. During the flapping process, the auxiliary silt removal part will drive the solid impurities deposited thereon to be relatively passive with the silt scraper, thereby realizing stable stirring of the deposited solid impurities, so that the stirred solid impurities will pass over the silt scraper with the help of the through groove 8 and be washed and carried away by the flowing water, thereby slowing down the speed of the solid impurities deposited in the drainage well, and reducing the influence of the deposited solid impurities on the drainage function of the drainage well.
[0029] like Figure 1-Figure 3As shown, the auxiliary silt removal part includes an internally hollow silt connection piece 9, which can reduce the overall mass of the silt connection piece 9, so that the silt connection piece 9 can float better when subjected to buoyancy. The above-mentioned silt connection surface 4 is the top surface of the silt connection piece 9, and the bottom of the silt connection piece 9 is fixedly connected with a support pipe 10 by welding. The bottom surface of the support pipe 10 is set as an arc surface. A rotating hole 11 for the support pipe 10 to penetrate is opened on the inner bottom surface of the well body 1. A rigid sheet 12 that can be abutted against the bottom surface of the support pipe 10 is fixedly connected to the inner bottom surface of the rotating hole 11 by adhesive bonding. The top surface of the rigid sheet 12 is set as a smooth surface. The set rigid sheet 12 is used to achieve The stable support of the support tube 10 and the silt connecting piece 9 above it makes it possible for the friction force generated between the support tube 10 and the rigid plate 12 to be smaller when the support tube 10 is in contact with the top surface of the rigid plate 12 and when the support tube 10 rotates relative to the rigid plate 12, so that the rotation process of the support tube 10 and the silt connecting piece 9 is more stable, thereby ensuring that the dredging effect of the auxiliary dredging part is more stable.

The floating plate 13 is set to a high molecular polyethylene material. This setting ensures that the floating plate 13 can be subjected to stable buoyancy when immersed in water. The silt connection member 9 is fixedly connected with a guide tube 14 whose bottom passes through and communicates with the bottom side of the floating plate 13 by welding. The top opening of the guide tube 14 is set to an oblique opening. This setting ensures that water can flow into the guide tube 14 with the help of the top opening of the guide tube 14 and under the action of the guide tube 14 drainage, the water can stably enter the bottom of the floating plate 13 and the silt connection member 9, so that the water can stably achieve the lifting of the silt connection member 9 and the floating plate 13, ensuring that the top surface of the silt connection member 9 can stably resist the silt scraper. The silt scraper is provided with a clearance groove 15 for the guide tube 14 to move. The set clearance groove 15 is used to provide a clearance effect for the guide tube 14 during the swinging of the silt connection member 9, ensuring that the silt scraper can swing stably, thereby ensuring that the auxiliary silt removal function of the auxiliary silt removal part can be stably realized.

On the other hand, with the help of the provided clamping blocks 22 and the card grooves 21, the rotation process of the manhole cover 20 relative to the mounting ring seat 18 is stably restricted, ensuring that the state of the manhole cover 20 in the mounting ring seat 18 is more stable.
[0033] like Figure 1-Figure 4 As shown, the manhole cover 20 is rotatably connected to a rotating seat 23 by means of an axial hole, the bottom of the rotating seat 23 is fixedly connected to a plug plate 24 by welding, the plug plate 24 is fixedly connected to a connecting plate 25 by welding, the connecting plate 25 is fixedly connected to a spring 26 fixedly connected to the manhole cover 20 at the top by welding, and a plug slot 27 for inserting the plug plate 24 is provided on the driving tube 16. After the plug plate 24 is inserted into the plug slot 27, the plug plate 24 will be driven to rotate during the rotation of the driving tube 16, which will drive the spring 26 to be twisted and elastically deformed. When the force applied to the driving tube 16 When the force of the water flow disappears or is less than the elastic force generated by the elastically deformed spring 26, the elastic force generated by the elastically deformed spring 26 will drive the driving tube 16 to reset, and then drive the auxiliary dredging part as a whole to reset, thereby realizing the overall swing of the auxiliary dredging part, and stirring the solid impurities on the docking dredging piece 9, and then the accumulated solid impurities are taken away under the flushing action of the flowing water, thereby achieving the dredging effect of the entire structure, slowing down the speed of solid impurities accumulating in the drainage well, and then reducing the influence of the accumulated solid impurities on the drainage function of the drainage well, and at the same time, it can also reduce the frequency of dredging the drainage well, making the use of the entire structure more convenient.
