Planting, rainwater collection and utilization integrated building outer wall greening device

Abstract

The invention discloses a planting, rainwater collection and utilization integrated building outer wall greening device, which is arranged on the wall of a building. The building outer wall greening device comprises a water reservoir, a hanging arm, a connecting pipe and a planting pot for planting a plant. The planting pot is positioned outside the building and arranged on the wall, and the water reservoir is positioned inside the building; one end of the hanging arm is pivoted with the wall, and the other end of the hanging arm is pivoted with the water reservoir; one end of the connecting pipe is connected with the bottom of the planting pot, and the other end of the connecting pipe is connected with the water reservoir; and the hanging arm downwards rotates to drive the bottom or the top of the water reservoir to be lower than the bottom of the planting pot so as to collect rainwater, and the hanging arm upwards rotates to drive the bottom or the top of the water reservoir to be higher than the bottom of the planting pot so as to water the plant in the planting pot. The device can be used for collecting the rainwater and watering the plant by using the rainwater so as to save water sources and improve the watering efficiency; and meanwhile, the plant grown in the device can purify the air, save energy and beautify the environment.

Description

technical field [0001] The invention relates to a greening device for the outer wall of a building, in particular to a greening device for the outer wall of a building integrating planting, rainwater collection and utilization. Background technique [0002] Due to the construction of urbanization, a large number of buildings made of sand and stone are densely gathered together. The buildings occupy the land on which plants grow, resulting in the lack of plants and the imbalance of today's ecological environment. As we all know, the formation of desertification is actually the process of sand and stone accumulation, and the building itself is formed by the accumulation of sand and stone. Therefore, an extensive city that only builds houses but does not do greening projects is equivalent to man-made desertification. Contrary to the green concept advocated today. [0003] In order to see some greenery in densely packed buildings, people usually choose to plant some plants on p...

Problems solved by technology

[0005] The above-mentioned watering methods often only moisten the soil on the surface of the planting pot, and the parts of the root system of the plant that need water are often impermeable. If the roots of the plant need to be soaked, the amount of water supply must be increased, which will cause excess water to seep into the planting pot bottom

It flows to the outside world through the leakage hole, and there is no collection and reuse measures. On the one hand, it causes waste of water resources, and on the other hand, it pollutes the ground, thus increasing the burden of cleaning.
