Problems solved by technology

The current rainwater collection device mainly collects the middle and late rainwater after the initial abandonment for storage and use, but can separately collect natural rainwater and rainfall runoff at different stages of the rainfall process, and there is no mature equipment for automatic collection devices that meet the monitoring of rainwater quality.

Embodiment

[0018] There are the following control modes for collecting runoff rainwater:

[0019] (1) Rainfall control mode: Determine the rainwater collection frequency according to the set rainfall (rainfall intensity or cumulative rainfall), that is, when the rainfall runoff corresponding to a certain amount of rainfall is required, the rain gauge triggers the single-chip control device to start the submersible pump. Send rainwater to the rain collector, close the vent valve of the rain collector, open the drain valve of the rain collector, the submersible pump will automatically shut down after the set time T1, and the drain valve will remain open, and the corresponding rainfall will be collected in the sampling bottle after the set time T2 , the drain valve is closed, the vent valve is opened, and the excess rainwater in the rain collector is discharged. When the rain gauge is triggered next time, the submersible pump is started again, and the same process continues, except that a...

Abstract

The invention discloses a method of implementing an automatic control and storage device used for collection of natural rainwater or rainfall runoff, relating to the fields of environmental protection and water supply and drainage work. According to the invention, by a single-chip microcomputer control device, parameters such as rainfall, rainfall time or flow are taken as trigger conditions, rainwater of different characteristic stages in a rainwater collector can be stored into different independent sampling bottles by automatic control. The rainwater collector is connected with a submersible pump to collect the rainfall runoff, and also connected with a rainwater receiving funnel to collect the natural rainwater. A distributor on the rainwater collector can automatically fill the rainwater in the rainwater collector. The device has the characteristics that firstly, the device is suitable for the fields and occasions without an alternating current power source, remote transmission of data can be automatically controlled, and a possibility of unattended automatic collection of rainwater sample in the fields at night can be achieved; secondly, the rainwater of different stages can be automatically collected according to the given rainfall or time, and the device is suitable for monitoring the change of water quality of the rainwater along with factors such as rainfall and time; thirdly, rainwater under various conditions such as natural rainwater and rainfall runoff at different catchment areas can be collected.

Description

technical field [0001] The invention relates to an automatic rainwater collection device, which is an automatic control device in the fields of water supply and drainage, urban pipe network and environmental protection. Background technique [0002] Rainwater is a water resource that can be used in addition to surface water and groundwater. However, due to the pollution of the atmosphere and surface catchment areas, rainwater runoff also causes non-point source pollution that is difficult to control. The use of rainwater and the corresponding pollution control first need to monitor the water quality of rainwater and rainfall runoff. Due to the unpredictable climate, the difficulty of monitoring lies in the collection of characteristic rainwater and rainfall runoff during the rainfall process. The current rainwater collection device mainly collects the middle and late rainwater after the initial abandonment for storage and use, but can separately collect natural rainwater an...
