Description

Technical Field

[0001] This utility model relates to the field of drainage ditch cover technology, and more specifically, it relates to a drainage ditch cover that prevents clogging. Background Technology

[0002] Drainage ditch covers, also known as ditch covers, manhole covers, and sewer covers, were originally made of cement and cast iron. Because they were easily damaged during normal use and the replacement cost was high, steel grating was later used for pressure welding. The main function of drainage ditch covers is to divert rainwater from the road surface during rain and allow the accumulated water on the road surface to enter the city's sewage treatment system.

[0003] According to the search, the utility model patent with Chinese application number CN202020707250.X discloses a drainage ditch cover for preventing blockage, including a cover body, a number of drainage grooves symmetrically opened on the upper surface of the cover body, a number of arc-shaped blocks fixedly connected symmetrically on the upper surface of the cover body, and a connecting box fixedly connected to one side wall of the cover body.

[0004] When in use, the output end of the second waterproof motor will rotate, driving the rotating block to rotate. The rotation of the rotating block will cause the connecting block to rotate. Through the continuous rotation of the connecting block, the leaves, plastic bags and other garbage in the drainage ditch will be deformed to a certain extent. When the leaves, plastic bags and other garbage are deformed to a certain extent, a certain gap will be created between the leaves, plastic bags and other garbage and the drainage ditch, and water can be drained through these gaps. However, some leaves will cover the top of the cover plate. Since the connecting block is located inside the drainage ditch, it is not convenient to clean the leaves on the top of the cover plate. In addition, the cover plate is placed directly inside the drainage ditch, and the stability of the cover plate is poor when placed on the drainage ditch. Utility Model Content
