Problems solved by technology

These devices have greatly improved the efficiency of sampling and reduced the workload, but manual operation is still inseparable from the sampling process. Even if some devices have a high degree of automation, the start-up of the device still requires the manual operation of the sampler, which cannot be done in time. The field sampling work with predictable rainfall time and long sampling distance has brought great difficulties

Embodiment 1

[0020] Embodiment 1: The device is assembled according to each part of the figure, and then the device is connected to the rainwater pipe on the roof that needs to be collected. When it starts to rain outdoors, the rain sensor (1) generates an electrical signal, which is transmitted to the controller (3), and the controller (3) The transmission signal opens the solenoid valve on the runoff collection main pipe (4), and simultaneously opens the solenoid valve (8) of the leftmost runoff collection branch pipe (7), and the valves on the remaining branch pipes remain closed. , the rainwater runoff is continuously poured into the No. 1 sampling bottle (9), if the rainfall intensity is relatively large, the No. 1 container will be filled within the sampling time limited by the timer (2), at this time, the No. 1 liquid level gauge (6) will generate a feedback signal , send it to the controller (3), and then control the solenoid valve (8) on the No. 1 branch pipe to close, and the sole...

Abstract

The invention discloses a device used for automatic collection and storage of rainfall runoff, relating to the field of environmental engineering and water supply and drainage engineering. According to the device, rainfall time is taken as a triggering condition, rainfall runoff generated at different time periods is automatically controlled to be collected and stored into an independent samplingbottle under a rainfall condition. The device consists of a rainwater sensor, a timer, a controller, a runoff collecting main pipe, a transmitter, a level meter, a runoff collecting branch pipe, a solenoid valve and a sampling bottle. The device has the characteristics of high degree of automation, simple structure, use convenience and the like, and is suitable for collecting roof rainfall runoffformed by rainfall at any time period, and researching the change rule of rainwater runoff quality along with rainfall time.

Description

1 technical field [0001] The invention relates to an automatic sampling device for rainwater runoff, which belongs to the field of environmental engineering and water supply and drainage engineering. The invention belongs to the field of in-situ ecological restoration of river channel water bodies, in particular to a novel carpet-type artificial aquatic plant. 2 Technical Background [0002] Rainwater runoff pollution is one of the important components of non-point source pollution, which means that under the leaching and scouring action of rainwater runoff, pollutants in the atmosphere, ground and soil diffuse into surface water and groundwater to cause water environment pollution. Compared with other pollution, it often has the randomness of pollution occurrence and the uncertainty of pollutant discharge, which has attracted more and more attention from all over the world. Global environmental protection workers have invested a lot of manpower and material resources to car...
