The invention discloses a filtering anti-blocking structure of a drainage
pipe for road maintenance, and relates to the technical field of
sewage discharge. The filtering anti-blocking structure of the drainage
pipe for road maintenance comprises a first pipeline, and the top of the first pipeline is fixedly connected with a first filtering mechanism. According to the filtering anti-blocking structure of the drainage
pipe for road maintenance,
sewage is preliminarily filtered by arranging the conical filtering cylinder, and the
sewage is secondarily filtered by arranging the first filtering disc and the second filtering disc in a matched manner, so that the situation that a single filtering net is easily and instantly blocked by large-particle impurities is avoided, the pressure of post-stage filtering is reduced, and the filtering efficiency is improved. A limiting rotating
ring block is arranged, a first driving motor is started, the limiting rotating
ring block is finally driven to rotate through gear meshing, at the moment, a rotating ball continuously slides on the surface of the limiting rotating
ring block, and a first spring is matched, so that a second fixing block periodically reciprocates; finally, the banister
brush is promoted to clean the through holes of the conical filter
cartridge, and the through holes are prevented from being blocked.
