Rainwater collecting device and method

Abstract

The invention discloses a rainwater collecting device and method. The device comprises a rainwater collecting part and a control part. The rainwater collecting part comprises a rainwater collecting pipe and a water storage tank; an output end of a controller of the control part is in signal connection with an air pump and a valve. A pressure sensor detects the rainfall information and falling direction information of rainwater and transmits the rainfall information and the falling direction information to the controller, and the controller receives the rainfall information and the falling direction information and controls the jet direction and jet flow of an air jet opening by controlling the air pump and the valve to ensure that the flow and direction of ejected airflow at the air jet opening can assist the rainwater collecting pipe in collecting the rainwater. The device and the method solve the technical problems in the prior art that rainwater collecting systems have a small rainwater collecting amount and low collecting efficiency and secondary pollution caused by the collected rainwater is serious; the effects that the collecting amount is large, the collecting efficiency ishigh and the collected rainwater is cleaner are achieved.

Description

technical field [0001] The invention belongs to the field of water resources treatment, and in particular relates to a rainwater collection device and a collection method. Background technique [0002] The total amount of water resources in my country is abundant, but there are problems of uneven distribution of water resources, huge differences between the year and the year, poor per capita water resources and serious water shortages. In recent years, it has suffered from severe drought continuously. Among the more than 600 cities in the country, more than 400 are short of water, and more than 100 of them are seriously short of water. At the same time, the population continues to grow. It is estimated that by 2030, my country's per capita water resources will drop from the current 2,200 cubic meters to 1,700 to 1,800 cubic meters. The problem of water shortage is becoming more and more serious. [0003] Precipitation is the main source of surface water resources, how to fu...
