A self-clearing mechanism for gravity flow rainwater bucket

Abstract

The invention relates to the technical field of drainage engineering, and discloses a self-clearing mechanism for a gravity flow rainwater bucket, comprising a fixed seat, the inner cavity of the fixed seat is provided with a drain pipe, and the upper end of the middle part of the fixed seat is fixedly connected with a drainage pipe. The upper end of the inner cavity of the fixed seat is movably connected with an anti-blocking cylinder located on the outer surface of the drainage cylinder, and the upper end of the anti-blocking cylinder is fixedly connected with a rotating rod. In the present invention, by adding a self-clearing structure, when the rainwater bucket discharges rainwater normally, the driving piece can be pushed by the impact force when the rainwater falls, so that the anti-blocking cylinder is driven to rotate under the action of the driving piece, so that the rotating rod The anti-blocking cylinder rotates to clean the side wall of the drainage cylinder, so that the fallen leaves, silt and other foreign matter adsorbed on the surface of the drainage cylinder can be broken or separated from the drainage cylinder under the agitation of the rotating rod. When working, it is easy to be affected by foreign objects on the drainage efficiency.

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...
