A rainwater bucket for roof drainage

Abstract

The invention discloses a rainwater hopper for roof drainage. The rainwater hopper is installed between a gutter for guiding rainwater and a drainage pipeline for draining rainwater. The rainwater hopper comprises a hopper body, a grating layer and a short tube, wherein the hopper body is a vertically-arranged barrel, the lower end of the hopper body horizontally extends inwards to form a first circular ring, the hopper body is installed in the gutter in an embedded mode, and the upper end of the hopper body is flush with the gutter and is connected with the gutter; the grating layer is installed above the hopper body and comprises a first supporting ring arranged horizontally and columnar vertical ribs perpendicular to the upper surface of the first supporting ring; the short tube is installed below the hopper body and is a vertically-arranged barrel, the upper end of the short tube is connected with the inner side of the first circular ring, and the diameter ratio of the short tube to the hopper body is 1:1.2-1.5. The rainwater hopper has a simple structure, large water drainage quantity and low cost, can be applied to automatic flow distribution and drainage under various severe weather conditions of large rainfall and heavy snow, has popularization value and is conveniently produced on a large scale.

Description

technical field [0001] The invention relates to a drainage device, in particular to a rain bucket used for roof drainage. Background technique [0002] The existing building roof drainage system generally adopts the combination of gutter, rainwater bucket and rainwater pipe to drain and discharge rainwater. Existing rainwater buckets are generally located at the entrance of the rainwater pipeline from the gutter. The rainwater bucket has a rectifying grille device, which can quickly drain the rainwater from the roof, avoid the formation of an excessive vortex, stabilize the water level in front of the bucket, and effectively block large debris. Rainwater buckets are divided into 87 types, 79 types, 65 types, siphon type rainwater buckets, and weir flow type rainwater buckets. Generally, Type 87 and siphon rainwater buckets are used more. [0003] However, when there is a lot of rain in the rainy season, a large number of drainage devices are often required to discharge th...

Problems solved by technology

[0003] However, when there is a lot of rain in the rainy season, a large number of drainage devices are often required to discharge the rainwater. The existing rainwater bucket has a weak drainage capacity and cannot withstand excessive rainfall. When the water flows into the bucket body, it will generate a vortex, overflow the rainwater bucket, and accumulate in the gutter Surface and near rain buckets

In addition, in Northeast China and other areas where there is heavy snow in winter, there is a lot of snow on the roof. When the snow melts, the snow water envelops snowballs and accumulates in the bucket body, blocking the discharge of snow water.
