Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 and figure 2 As shown, the rainwater collection device of the present invention includes a rectangular diversion tank 1 and an over-standard rainwater abandonment opening and closing mechanism arranged on the housing of the rectangular diversion tank 1, and a pollutant concentration detection device is arranged in the rectangular diversion tank 1 3. The control module 9 is connected to the opening and closing mechanism of the excess rainwater abandonment flow and the pollutant concentration detection equipment 3, and the flow velocity detection device 2 and the water depth detection device 22 connected to the control module 9 are arranged in the rectangular diversion tank 1, and the flow velocity detection device 2. The water depth detection device 22 and the pollutant concentration detection device 3 are arranged in front of the

Abstract

The invention discloses a rainwater collecting device for discharging rainwater with high pollution concentration and then collecting clean rainwater, which can effectively discharge the rainwater with high pollutant concentration. The minimum water flow time from pollutant concentration detection equipment in the rainwater collecting device to a super-standard rainwater flow abandoning opening-closing mechanism is greater than or equal to the sum of the maximum opening time of the super-standard rainwater flow abandoning opening-closing mechanism, the maximum closing time of the super-standard rainwater flow abandoning opening-closing mechanism and the reaction time of a control module. The rainwater collecting device can ensure that high-concentration polluted rainwater is discharged from rainwater runoff in time and the clean rainwater is selectively collected so as to improve the clean water collecting effect, and is suitable for popularization and application.
