Initial rainwater discarding well device with hydraulic automatic tipping bucket

Abstract

The invention discloses an initial rainwater discarding well device with a hydraulic automatic tipping bucket. The initial rainwater discarding well device comprises a water inlet pipe, the hydraulicautomatic tipping bucket connected with a rotary shaft and a discarding pipe, wherein both the water inlet pipe and a water outlet pipe are inserted into a well body, the well body is connected with abase, a partition wall is arranged in the middle of the well to separate a discarding well and a water outlet well, the hydraulic automatic tipping bucket is located below the front of a water outletof the water inlet pipe, rainwater enters the hydraulic automatic tipping bucket, then flows to the discarding well and then is drained away, and when rainfall is large, the hydraulic automatic tipping bucket turns over to guide rainwater to flow to the water outlet well and rotates around the rotary shaft, and the rotary shaft is fixed to the partition wall in the middle of the well. The initialrainwater discarding well device is suitable for discarding of initial rainwater of buildings and housing estates, has the advantages of automatically operating, saving construction investment and belong low in operating cost, good in hydraulic condition and convenient to construct and maintain and can automatically complete automatic shunting of dirtier initial falling rainwater and cleaner later rainwater.

Description

technical field [0001] The invention relates to a rainwater recovery and utilization device, in particular to a hydraulic automatic turning bucket primary rainwater abandonment well device. Background technique [0002] Due to the increase of population and the shortage of water resources, people pay more and more attention to the utilization of water resources. Under normal circumstances, rainwater is directly discharged to the sewer, which greatly wastes water resources and is likely to cause floods. If part of the rainwater can be properly collected (removing the dirty part of the initial rainwater), and then after simple treatment Reuse of water used for greening, car washing, air-conditioning replenishment water, landscape replenishment water, etc. will generate huge benefits, improve the water environment, and conform to the policy of sustainable resource utilization. [0003] However, the initial roof rainwater of buildings and residential areas contains a lot of imp...

AI Technical Summary

Problems solved by technology

This device can accurately control the automatic discharge of heavily polluted rainwater in the early stage of rainfall, but the cost is high, the later maintenance is difficult, and the operation is unreliable

[0011] (4) Existing problems of the commonly used concentrated initial rainwater abandonment device

In summary, the electric rainwater abandonment device is expensive, difficult to manage, and unreliable in operation; the initial rainwater abandonment device controlled by the volumetric method or the float valve needs to be manually switched on and off, and cannot be automatically controlled; the small pipe abandonment method is suitable for ditches. However, it is not suitable for the rainwater pipeline system commonly used at present, and the clean rainwater will continue to flow away at the end of the rainfall, wasting water resources
