Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, and specifically relates to a drainage structure for municipal engineering. Background Art

[0002] When the municipal drainage well drains water, rainwater directly flows into the drainage well through the drainage holes and then into the underground drainage pipeline. There are often some impurities in the rainwater. If not filtered, they may accumulate in the underground drainage pipeline, easily causing pipeline blockage and being laborious to clean. Therefore, it is necessary to filter the impurities entering the drainage well. Currently, domestic wastewater, rainwater, etc. in cities are all discharged through sewers. Drainage wells and manhole covers are arranged at intervals on the sewer for drainage and maintenance.

[0003] After retrieval, a Chinese patent with the publication number CN220266791U discloses a drainage structure for political engineering, including a mounting seat. A grid plate is arranged on the left side of the upper end of the mounting seat. An inclined filter plate is fixedly installed inside the mounting seat. A cleaning mechanism is arranged on the outer side of the frame of the inclined filter plate. A storage mechanism is arranged inside the mounting seat.

[0004] This structure adds an inclined filter plate inside the mounting seat. When sundries fall in, they are filtered on the upper end surface. The output end of the driving motor drives the screw to rotate, so that the carriage threadedly connected to the outside of the screw slides inside the rectangular hole of the frame of the inclined filter plate. A scraper is installed on the carriage, which can scrape the sundries on the inclined filter plate to a lower place for convenient collection.

[0005] However, this structure still has the following problems. The structure drives the scraper to move along the surface of the inclined filter plate through the mutual cooperation between the driving motor, the screw and the carriage, driving the sundries on the surface of the inclined filter plate into the collection box. And the number of drainage structures that need to be laid is relatively large, making the overall cost of the driving motors required in the structure relatively high. The driving motor only plays the role of driving the scraper to scrape sundries, and it is difficult to effectively improve the practicability of the structure. Content of the Utility Model
