Initial rainwater discarding well device with hydraulic automatic tipping bucket

Abstract

The invention discloses a device for an early stage rainwater abandonment well with a hydraulic automatic turning bucket, which includes a water inlet pipe, a hydraulic automatic turning bucket connected to a rotating shaft, and a jettison pipe. The partition wall separates the abandonment well and the water outlet well. The hydraulic automatic tipping bucket is located at the front and bottom of the water inlet pipe outlet. The rainwater enters the hydraulic automatic tipping bucket and then flows to the abandonment well. When the rainfall increases, the hydraulic automatic tipping bucket turns over and diverts the rainwater When it flows to the outlet well, the hydraulic automatic tipping bucket rotates around the rotating shaft, and the rotating shaft is fixed on the partition wall in the middle of the well. This invention is suitable for the initial rainwater abandonment of buildings and residential areas. It has automatic operation, low construction investment, low operating cost, and good hydraulic conditions. , The construction and maintenance are convenient, and the goal of automatically diverting the dirty initial rainwater and the cleaner late rainwater can be automatically completed.

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
