Rainwater irrigation connecting device for greenbelt under building

Abstract

The invention relates to a rainwater irrigation connecting device for a greenbelt under a building. The device is connected with a rainwater down pipe of the building and can effectively solve the problem in the effective rainwater irrigation of the greenbelt under the building. The rainwater irrigation connecting device is structurally characterized in that a water inlet pipe is communicated with a water outlet pipe, a water drain pipe which is communicated with the water inlet pipe is installed on the water inlet pipe below the water outlet pipe, a bottom cover is installed at the bottom ofthe water inlet pipe corresponding to a water inlet, a bolt which is arranged in the water inlet pipe is installed in the center hole of the bottom cover, a nut is installed on the bolt which stretches out of the external part of the bottom cover, a spring is installed on the bolt in the water inlet pipe, the lower part of the spring is arranged on the bottom cover, the upper end of the spring isfixed with the upper end of the bolt, a piston which is arranged in the water inlet pipe is fixedly installed at the top of the spring, the bottom cover, the piston, the spring, the bolt and the nut form the rainwater drainage adjuster, the upper end of the water inlet pipe is the water inlet and a filter screen is installed at the mouth part of the water outlet pipe which is communicated with the water inlet pipe. The rainwater irrigation connecting device for the greenbelt under the building has the advantages that the structure is simple, the device is convenient to install and use, the urban tap water is saved and the economic and social benefits are remarkable.

Description

technical field [0001] The invention relates to irrigation equipment, in particular to a rainwater irrigation connection device for green areas under buildings. Background technique [0002] With the development of the city, there are more and more large-scale buildings and overpasses, and the green space under the buildings (including bridges) is also increasing. Neglect, especially in the rainy season, most of the green space does not need to be irrigated, and it is easy for people to ignore the irrigation of the green space under the buildings that cannot be drenched by rain, resulting in drought and even the death of flowers and plants, while the rain is not fully utilized. Therefore, the effective irrigation of rainwater and the full utilization of rainwater in the green space under the buildings are technical problems that must be solved. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the object ...
