Kind Code:
A1
Abstract:
A flooding and backup prevention drainage well cover and an operation method, related to the technical field of drainage well covers. The cover comprises: an upper-layer well cover (1), a lower-layer well cover (2), and a garbage collection apparatus (3); the upper-layer well cover (1) comprises an upper-layer cover body (12) and an upper well ring (11), the upper-layer cover body (12) comprising a sealing part (121) and a grate part (122); the lower-layer well cover (2) comprises a lower-layer cover body (22) and a lower well ring (21), the lower-layer cover body (22) comprising a securing frame (221) and a filter screen (222), the filter screen (222) acting in concert with the grate part (122) allowing rainwater to pass through while retaining garbage on the filter screen (222); the lower-layer well cover (2) comprises a garbage cleanup sliding block (23), the garbage cleanup sliding block (23) being able to push garbage into the garbage collection apparatus (3) and clean the filter screen (222), thereby preventing clogging of the well cover; the upper-layer cover body (12) and the lower-layer cover body (22) can be opened when facing a large amount of drainage water, thereby maximizing the drainage efficiency of the well cover so as to satisfy flooding prevention requirements; a barrier (5) is further arranged in the well cover, and when the upper-layer cover body (12) is opened, the barrier (5) rises to block the drainage well opening, thereby preventing pedestrians from falling into the well; and when the lower-layer cover body (22) is opened, the garbage collection apparatus (3) is lifted and abuts tightly against the sealing part (121), thereby preventing rainwater from entering the garbage collection apparatus (3), and improving the garbage load capacity of the apparatus.
