[0028] Working principle: When the utility model is used, first, sewage enters the drainage box 1 through the water inlet pipe 2. After the sewage enters the drainage box 1 with solid debris such as stones, it will first fall on the top surface of the first buffer plate 5. After the first buffer plate 5 is impacted, it will move downward, and the first buffer plate 5 will drive the connecting rod 4 to descend. The connecting rod 4 will drive the connecting plate 6 to descend. The connecting plate 6 will descend and squeeze the first spring 7. The first spring 7 will be squeezed to absorb the impact force, thereby performing the first buffering on the impacted stones. Then, the sewage will slide along the left and right sides of the top surface of the first buffer plate 5 with solid debris such as stones, and fall on the top surfaces of the two second buffer plates 9. After the second buffer plate 9 is impacted, it will move downward, and the second buffer plate 9 will drive the sleeve 11 to descend. After the sleeve 11 descends, it will squeeze the second buffer spring 13. The second buffer spring 13 will be squeezed to absorb the impact force, thereby performing the second buffering on the impacted stones. Then, the sewage will pass through the second buffer plate The top surface of 9 slides down toward the middle of the inner cavity of the drainage box 1, and finally falls on the top surface of the filter screen 3, so that the filter screen 3 filters the sewage. Through two bufferings, the force of the stone falling on the filter screen 3 can be greatly reduced, so that the stone that follows the sewage into the drainage box 1 is not easy to damage the filter screen 3, thereby improving the service life of the filter screen 3. The stone falling on the filter screen 3 will slide to the left and right sides of the filter screen 3, and pass through the drop opening 15 and fall into the collection box 14, and the water entering the collection box 14 will return to the drainage box 1 through the connecting pipe 16 after filtration, and finally the water will be discharged to the outside of the drainage box 1 through the drainage pipe 22, and the cover plate 17 can be pulled up and pulled out of the cleaning opening, so that the cover plate 17 can be taken out of the collection box 14, and then the stones left on the top surface of the filter screen 3 and located in the collection box 14 can be taken out through the cleaning opening, and finally the sealing door 23 is opened to expose the taking opening, so as to facilitate the cleaning of the stones that cannot roll to the left and right sides on the filter screen 3.

[0029] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
