Rainwater collection and reuse system

Abstract

The invention discloses a rainwater collection and reuse system. The invention judges whether the filter screen is blocked by comparing the water volume in the water inlet pipe and the water outlet pipe of the primary rainwater filter device, and if it is blocked, opens the valve at the bottom of the primary rainwater filter device, and drives the scraper downward to scrape the blockage on the filter screen remove, enter the drainpipe, and then reset the device. In this way, the blocked rainwater primary filter device can be cleaned and maintained in time, so that the entire rainwater collection and reuse system can work stably for a longer period of time, and better relieve the urban water shortage and the pressure on the urban drainage system during a large amount of precipitation.

Description

technical field [0001] The invention relates to the field of rainwater collection and reuse, in particular to a rainwater collection and reuse system. Background technique [0002] Water, the source of life, is an extremely precious resource. my country's water resources are not rich, and 2 / 3 of the cities in the country are short of water. With the acceleration of urbanization, the rapid increase in water consumption for landscape water, road flushing, greening and car washing in the city makes the already tense water resources even more scarce. At the same time, due to the advancement of urbanization, more bottom surfaces are covered by various buildings and roads, which prevents rainwater from seeping into the ground and increases the pressure on the urban drainage system. In recent years, it is not surprising to hear reports of urban waterlogging. One way to solve the above problems is to collect and reuse the water that falls to the city. In this way, the rainwater ...

Problems solved by technology

And the filter device that uses at present comprises shell and is arranged on the hanging basket in the shell, and the solid pollutant that increases after rainwater enters hanging basket is filtered out, and hanging basket will be blocked by pollutant gradually after using for a period of time, so just Hanging basket needs to be cleaned

At present, the hanging basket is generally cleaned manually. Manual cleaning is often carried out in a regular manner, but this method is not good. Sometimes the hanging basket does not need to be cleaned when cleaning, and sometimes the hanging basket is blocked and missing. It is time to clean up, thus affecting the collection and utilization of rainwater
