Self-unblocking mechanism of gravity flow rainwater hopper

Abstract

The invention relates to the technical field of drainage engineering, and discloses a self-unblocking mechanism of a gravity flow rainwater hopper. The self-unblocking mechanism comprises a fixed base, a drainage pipe is arranged in an inner cavity of the fixed base, a drainage cylinder is fixedly connected to the upper end of the middle of the fixed base, an anti-blocking cylinder located on theouter surface of the drainage cylinder is movably connected to the upper end of the inner cavity of the fixed base, and the upper end of the anti-blocking cylinder is fixedly connected with a rotatingrod. By additionally arranging a self-unblocking structure, when the rainwater hopper normally drains rainwater, a driving piece can be pushed through impact force generated when the rainwater falls,the anti-blocking cylinder is driven to rotate under the action of the driving piece, so that the rotating rod cleans the side wall of the drainage cylinder under the action of rotation of the anti-blocking cylinder, fallen leaves, sludge and other foreign matters adsorbed on the surface of the drainage cylinder can be crushed or separated from the drainage cylinder under the stirring action of the rotating rod, and the situation that the drainage efficiency of the rainwater hopper is easily influenced by the foreign matters during normal work is avoided.

Description

technical field [0001] The invention relates to the technical field of drainage engineering, in particular to a self-clearing mechanism for a gravity flow rainwater bucket. Background technique [0002] The rainwater bucket belongs to the branch of the metal falling water system. It is located at the entrance where the roof rainwater enters the rainwater pipe from the gutter. The traditional rainwater bucket is divided into two types: the gravity flow rainwater bucket and the siphon rainwater bucket. The gravity flow rainwater bucket is mainly through gravity. The rainwater is automatically discharged, avoiding the accumulation of a large amount of rainwater on the roof in rainy and snowy weather, and preventing large foreign objects from falling into the downpipe, causing the water pipe to be blocked. [0003] When the traditional gravity-flow rainwater bucket is normally discharged from the roof, there are often fallen leaves, foreign objects, silt, etc. attached to the ou...
