Rainwater collection and car washing device based on self-controlled purification and automatic water supplementing

Abstract

The invention provides a rainwater collection and car washing device based on self-controlled purification and automatic water supplementing and belongs to the technical field of water treatment. Thedevice comprises a self-controlled rainwater filtering device, a self-service car washing device and an automatic rainwater supplementing device based on water level control, and the self-controlled rainwater filtering device senses the rainfall condition through a rainfall sensor, automatically turns on a filter to achieve rainwater purification during rainfall and automatically conducts back washing on the filter after rainfall is ended; a large-volume underground rainwater collection pool is adopted for collection rainwater, a light and small-volume water storage bucket is adopted for providing water for washing a car, and a liquid level relay is used for automatically controlling water supplying from the rainwater collection pool to the water storage bucket. The rainwater collection and car washing device can achieve automatic purification of the rainwater and automatically supplementing of the water for washing the car, can effectively achieve recovery and utilization of urban rainwater and can remarkably facilitate self-service car washing management of urban residents.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to a device for separating, purifying and reusing natural precipitation, in particular to a rain-collecting car-washing device capable of realizing non-powered purification of rainwater and automatic replenishment of rainwater. Background technique [0002] With the process of urbanization in our country, the number of residents' car ownership continues to increase. According to the survey, the number of civilian vehicles in my country has increased from 16 million in 2000 to 290 million at the end of 2016, ranking second in the world. The increase in motor vehicles has led to the rapid development of the car wash industry, and the water use and water conservation issues in the car wash industry have therefore become an important part of public domestic water management. Combining urban rainwater utilization with parking lot construction can not only save limited water resourc...
