Siphon rainwater bucket for building drainage

Abstract

The invention relates to the technical field of drainage, and discloses a siphon rainwater bucket for building drainage, which includes a grille cover, a bucket body, an anti-vortex device and a short water outlet pipe, and the grille cover and the bucket body are respectively fixed and installed on the anti-vortex device The upper and lower ends of the upper and lower ends, the short water outlet pipe is fixedly sleeved under the bucket body, the anti-vortex device includes an anti-vortex cover, the anti-vortex cover is in the shape of a ring column, and the inner wall of the anti-vortex cover is welded with a partition, The inside of the anti-vortex cover is provided with a movable bucket, and the movable bucket slides up and down along the outer wall of the partition. The invention can automatically adjust the size of the gap for rainwater to enter the rainwater bucket according to the amount of rainwater through the up and down movement of the movable bucket plate, so that the gap can only allow rainwater to pass through, and the air carried by the flow of rainwater cannot enter the siphon rainwater bucket , to reduce the amount of air entering the rain bucket with rainwater, thereby promoting the formation of the siphon effect.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a siphon rainwater bucket for building drainage. Background technique [0002] At present, there are mainly two types of rainwater buckets used in buildings, one is the gravity type rainwater bucket, which is a traditional rainwater bucket, which relies on the gravity of rainwater to discharge rainwater; the other is the roof siphon rainwater bucket, which It is a new type of rainwater bucket, which is used with the siphon drainage system. When the amount of rainwater is small, it relies on the gravity of the rainwater to discharge it like the gravity rain bucket. When the rainwater accumulates to a certain amount, it uses the siphon effect to continuously pump the rainwater and speed up the drainage of the rainwater. . Driven by the new roof rainwater drainage system, the traditional gravity rainwater bucket has been gradually replaced, and more and more new buildings adopt th...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the disadvantages of the existing siphon rainwater bucket proposed in the background technology during use, the present invention provides a siphon rainwater bucket for building drainage, which can accelerate the accumulation of rainwater, reduce the time for forming a siphon, and can further reduce the siphon rainwater bucket. In order to achieve the advantage of improving the drainage effect of the siphon rainwater bucket, it solves the problems of long siphon formation time and more air entering the siphon rainwater bucket in the above background technology
