Siphon rainwater hopper for building drainage

Abstract

The invention relates to the technical field of drainage, and discloses a siphon rainwater hopper for building drainage. The siphon rainwater hopper comprises a grid cover, a hopper body, a reverse vortex device and a water outlet short pipe; the grid cover and the hopper body are fixedly installed at the upper end and the lower end of the reverse vortex device respectively, and the water outlet short pipe fixedly sleeves the lower part of the hopper body; and the reverse vortex device comprises a reverse vortex outer cover, the anti-vortex outer cover is in an annular column shape, partitionplates are welded to the inner wall of the reverse vortex outer cover, a movable hopper disc is arranged inside the reverse vortex outer cover, and the movable hopper disc slides up and down along theouter walls of the partition plates. According to the siphon rainwater hopper for building drainage, through up-down movement of the movable hopper disc, the size of a gap for rainwater to enter therainwater hopper can be automatically adjusted according to the amount of rainwater, so that the gap only allows the rainwater to pass through, air carried and wrapped by flowing rainwater cannot enter the siphon rainwater hopper, the amount of air entering the rainwater hopper along with the rainwater is reduced, and thereby the formation of siphon effects is promoted.

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 two main types of rainwater buckets used in buildings, one is the gravity-type rainwater bucket, which is a traditional rainwater bucket that 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 like the gravity type rainwater bucket. . Driven by the new roof rainwater drainage system, the traditional gravity rainwater bucket has been gradually replaced, and more and more new buildings use the roof siphon rainwater drainage system. [0003] However, with the use of the roof siphon rainwater drainage system, more and more problems have emerged: ...

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
