Rainwater collecting and reusing system

Abstract

The invention discloses a rainwater collecting and reusing system. Whether a strainer is obstructed or not is judged by comparing the quantity of water in a water inlet pipe and the quantity of waterin a water outlet pipe in a primary rainwater filtering device. If the strainer is obstructed, a valve at the bottom of the primary rainwater filtering device is opened, and a scraper is driven to move down to scrap the obstructions on the strainer away, the obstructions enter a drain pipe, and then the device is reset. In this way, the obstructed primary rainwater filtering device can be cleanedand maintained in time, so that the entire rainwater collecting and reusing system can work stably for a long term, and the urban water shortage and the pressure of the urban drainage system in a large amount of precipitation can be well relieved.

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
