Abstract

A water saving automatic irrigation device used in the greening of residential areas is provided. The invention relates to a drip irrigation, water saving and humidity automatically controlled device used in the greening of residential areas, which pertains to a supporting facility of a group of buildings. The roof rainwater pipes of the device are connected to a reservoir which is connected to spray water pipes through pipelines and magnetic valves. A greening area is provided with a series of humidity sensors, the reclaimed water discharging tubes of a reclaimed water station are connected to the reservoir through make-up pumps and magnetic valves; water level sensors, humidity sensors and the magnetic valves, which are arranged in the reservoir are electrically connected with a measuring and controlling device. The device of the invention has high reliability and simple structure and realizes collection of rainfalls, automatic supplement and automatic regulation of the humidity of the greening drip irrigation plants of the residential areas.

Description

technical field [0001] The invention relates to an automatic control device for drip irrigation and water-saving humidity in community greening, which belongs to supporting facilities of building complexes. Background technique [0002] The collection and utilization of rainwater is not new. As early as the Qin and Han Dynasties in my country, there were records of building ponds to store rainwater for daily use, and the construction of water cellars in Northwest China has a history of hundreds of years. There are also examples of foreign countries collecting and utilizing rainwater. In the real modern sense, rainwater harvesting, especially urban rainwater harvesting, was developed in about 20 years from the 1980s to the 1990s. With the further acceleration of urbanization, the contradiction of urban water shortage has further deepened, and environmental and ecological problems have also expanded simultaneously. In order to solve a series of contradictions such as water s...
