A rainwater collection and utilization device for roof gardens

Abstract

The invention discloses a rainwater collection and utilization device for roof gardens, which relates to the technical field of rainwater collection and includes a rainwater collection device and a garden irrigation device. The rainwater collection device includes a lifting mechanism, a folding mechanism and an auxiliary mechanism. The lifting mechanism It consists of a base, a stepping motor, and a lifting sleeve. The water tank is fixedly installed on the top of the base, and the branch pipe is fixedly installed on the top of the water tank. In the present invention, through the setting of the rainwater collection device and the cooperation between the branch pipe and the stepping motor, the stepping motor can drive the lead screw to rotate during use. Threaded connection, and then when the lead screw rotates, it can drive the lifting sleeve to realize lifting under the action of the lead screw, and realize stable support operation under the action of the holding plate, thus playing the role of high degree of automation and improving space utilization, achieving a practical The purpose of high performance and wide application range.

Description

technical field [0001] The invention relates to the technical field of rainwater collection, in particular to a rainwater collection and utilization device for roof gardens. Background technique [0002] Rainwater harvesting is an important aspect for cities to improve the urban water environment, and green roofs have opened up an ecologically feasible way for urban rainwater harvesting. The large area of ​​hard impermeable surface in the city has caused a series of problems such as a large amount of urban rainwater discharge and the lowering of the groundwater level. However, the area of ​​the roof in the city accounts for about 30% of the hard surface of the entire city. Planting roofs can absorb and collect Part of the rainwater, increase the recycling of urban rainwater, slow down the discharge of rainwater, and improve the urban water environment. [0003] The Chinese patent with the application number CN205491884U discloses a rainwater collection and utilization devic...

Problems solved by technology

[0003] The Chinese patent with the application number CN205491884U discloses a rainwater collection and utilization device for roof gardens, although the rainwater collection and utilization device for roof gardens can store rainwater and discharge redundant Into the reservoir, and when the planting base needs water, it can be transported through the water diversion parts, making full use of the rainwater. However, the rainwater collection and utilization device used for the roof garden cannot realize the folding function, takes up a lot of space, and has a low degree of automation. , and it is not convenient for garden irrigation to make full use of rainwater, and has the disadvantages of low practicability and small application range. Therefore, a rainwater collection and utilization device for roof gardens is needed to solve the above problems
