Technical Field
[0001] The invention mainly relates to the technical field of water conservancy engineering drainage, and specifically to an anti-blocking drainage device for water conservancy engineering construction. Background Art
[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. At present, in the construction process of water conservancy projects, it is often necessary to excavate foundation pits. After excavation, it is necessary to drain the accumulated water in the foundation pit to prevent the accumulated water from affecting the construction. Traditional waterproof drainage devices basically use water pumps and filter screens for drainage. Since the position of the filter screen is fixed in the water and the pressure around the filter screen is relatively small during the water absorption process, solid matter and garbage in the water will gather, which is easy to cause blockage, thus affecting the normal drainage of the water pump.
[0003] In order to improve the influence of the above situation on the drainage efficiency, many solutions in the prior art adopt a scraping mechanism set outside the filter and other structures to scrape off the solid matter, garbage, etc. accumulated on the filter. However, due to the effect of water flow near the filter structure, the scraped solid matter, garbage, etc. will return to the vicinity of the filter with the flow of water, and the filter may still be blocked. The drainage efficiency of this type of anti-blocking drainage device still needs to be improved. Summary of the invention

[0020] The structure of the water absorption filter port 3 includes a top plate 31, a rib plate 32, and a bottom plate 33. A water inlet 30 is opened in the middle of the top plate 31. A plurality of rib plates 32 are fixedly connected between the top plate 31 and the bottom plate 33. A filter grille 34 is fixedly arranged on the outside of the rib plate 32.
