Building rainwater collecting and recycling device

Abstract

The invention discloses a building rainwater collecting and recycling device, which comprises a building, a rainwater collecting device, an underground garage, a first rainwater reservoir and a secondrainwater reservoir. The rainwater collecting device is fixedly mounted at the top of the building, and a water outlet end of the rainwater collecting device is connected with a water inlet end of the first rainwater reservoir in the underground garage at the bottom of the building through a water guide pipe mounted in a wall of the building. The building rainwater collecting and recycling deviceis structurally reasonable and simple, energy saving, environmental friendliness, building rainwater collecting and recycling and effectiveness in water resource utilization are realized, and qualityin toilet flushing and vehicle flushing with rainwater is guaranteed; rainwater used for vehicle washing is treated and then used for irrigation to realize rainwater collecting and recycling, and accordingly rainwater collecting and utilizing efficiency is effectively improved, municipal water consumption pressure in dry seasons is relieved, water consumption tension in the dry seasons is relieved, and high economic and social benefits and suitableness for popularization and utilization are realized.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and utilization, in particular to a building rainwater collection and recycling device. Background technique [0002] Rainwater is a high-quality natural water source, which has the characteristics of free use and light pollution. The orderly use of rainwater resources can achieve water conservation, water resource protection and conservation, reduce urban flood disasters, reduce water pollution, and improve the ecological environment. Multiple goals, 60% of the water for daily miscellaneous use can be considered to use rainwater to solve. However, the abundant rainwater in the existing rainy season is directly discharged, resulting in low utilization efficiency of rainwater resources, and the seasonality of precipitation in my country is obvious and concentrated, and the dry season and rainy season are distinct. The dry season is likely to cause water shortages in urban vegetation an...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a building rainwater collection and recycling device in order to solve the above problems, which solves the problem of direct discharge of abundant rainwater in the existing rainy season, resulting in low utilization efficiency of rainwater resources, and the obvious and concentrated seasonality of precipitation in our country. 1. The rainy season is distinct, and the dry season is likely to cause water shortages in urban vegetation and soil, which need to be artificially irrigated and replenished. With the popularity of vehicles, the water used for vehicle cleaning increases, which aggravates the problem of urban water shortages.
