Initial rainwater discarding system and control method thereof

Abstract

The invention relates to a rainwater collection system and a control method, and provides an initial rainwater discarding system and a control method thereof in order to solve the technical problem that initial pollution of roof rainwater in urban rainwater resources is difficult to control. The system comprises a discarding device, a rain gauge, a water level detector, a control unit, a water storage box, a filtering unit and a water purification box, wherein the water storage box, the filtering unit and the water purification box are in communication in sequence. The discarding device comprises a driving unit and a box body, a turning plate is arranged in the box body, a partition plate is arranged at the bottom of the box body, a first water outlet and a second water outlet are formed in the positions, located on the two sides of the partition plate, of the bottom of the box body correspondingly, and a water inlet is formed in the top of the box body. The two ends of the turning plate are located above the first water outlet and the second water outlet correspondingly, the output end of the driving unit is connected with the turning plate, and the control unit is electrically connected with the rain gauge, the water level detector and the driving unit and used for receiving detection data of the rain gauge and the water level detector and controlling the driving unit to workaccording to the detection data. According to the control method, rainwater discarding and collecting are controlled based on the system.

Description

technical field [0001] The invention relates to a rainwater collection system and a control method, in particular to an initial rainwater abandonment system and a control method thereof. Background technique [0002] With the continuous acceleration of the development of human society, the contradiction between supply and demand of water resources and serious pollution are becoming more and more prominent all over the world. In order to coordinate the contradiction between supply and demand of water and reduce the pressure on water resources, the value of urban rainwater collection and utilization is becoming more and more obvious. It can not only alleviate the problem of water shortage, but also improve the local microclimate to a certain extent. [0003] The comprehensive utilization of rainwater can not only relieve the pressure on the urban drainage system, but also effectively supplement water resources. For urban rainwater resources, roof rainwater accounts for an im...
