Automatic-adjustment variable-flow siphon rainwater hopper

Abstract

The invention discloses an automatic-adjustment variable-flow siphon rainwater hopper. The rainwater hopper comprises a shell assembly, a flow guide assembly and a rectification assembly; the shell assembly comprises a rainwater hopper body and a tail pipe, wherein the lower wall of the rainwater hopper body communicates with the upper end of the tail pipe; and the flow guide assembly comprises afirst guide rod, a flow guide cover and a first floating body, wherein the first guide rod is fixedly welded to the upper side of the rainwater hopper body, a first external thread is arranged on theupper portion of the first guide rod, and a first limiting nut is connected to the surface of the first external thread in a threaded mode. According to the rainwater hopper, the first floating body is arranged on the flow guide cover, a second floating body is arranged on a rectifier, the first floating body and the second floating body generate buoyancy in water, and along with ascending and descending of the water level, the flow guide cover and the rectifier can ascend or descend along guide rods; when the flow guide cover and the rectifier ascend, the water passing sectional area is increased, and the drainage flow is increased; and when the flow guide cover and the rectifier descend, the water passing sectional area is reduced, the drainage flow is reduced, and the requirement for rapid drainage can be met.

Description

technical field [0001] The present application relates to the technical field of rainwater buckets, in particular, to an automatic adjustment and variable flow siphon rainwater bucket. Background technique [0002] The rainwater bucket belongs to the branch of the building drainage system and is located at the entrance where the roof rainwater enters the rainwater pipe from the gutter. The rainwater bucket has a rectification grille device, which can quickly drain roof rainwater. The grille has a rectification effect, avoids the formation of excessive vortices, stabilizes the water level in front of the bucket, reduces aeration, quickly removes roof rainwater and snow water, and can effectively block large sundries. Rainwater buckets are usually used in conjunction with gutters and downspouts. [0003] The flow of the siphon rainwater bucket mainly depends on the cross-sectional area of ​​the water and the type of the short outlet pipe. The larger the cross-sectional area ...
