Water circulating system for growth of plants on building external wall

Abstract

The invention relates to the field of water circulation, in particular to a water circulating system for growth of plants on a building external wall. The water circulating system comprises the building external wall and a plurality of plant boxes which are uniformly arranged on the building external wall, wherein a water supply pipe and an air supply pipe are respectively arranged on the outer sides of the plant boxes, a material returning and turning over mechanism is arranged between adjacent up-down two layers of the plant box groups, each material returning and turning over mechanism comprises a climbing mechanism, a guiding mechanism and halving box bodies, a water dripping pipe is fixedly arranged at the top of each layer of the plant box groups, an elastic gate for blocking a corresponding connecting water pipe is arranged in each water retaining box, and a floating gate for blocking the corresponding water dripping pipe is also arranged in each water retaining box. According to the water circulating system for growth of plants on the building external wall and a working method, water quantity and pressure intensity in the water dripping pipes are controlled, so that plantsin each plant box can absorb moisture uniformly, and influence on the growth and development of the plants is avoided; and through the climbing mechanisms, the halving box bodies and the guiding mechanisms, impurities can be resupplied to the plants on the building external wall.

Description

technical field [0001] The invention relates to the field of water circulation, in particular to a water circulation system for growing plants on building exterior walls. Background technique [0002] Building greening refers to the environment where green plants can grow by directly or indirectly attaching to the building, such as flowerpots, planting blankets, etc. And / or the interior (usually refers to the interior wall) to create a green environment, to improve the environment, improve the aesthetics, and save energy. The concepts related to building greening include: building greening, wall greening, wall greening, roof greening, roof greening, roof garden, etc., and with the improvement of people's living standards, urban land resources in today's society are becoming more and more scarce. With the increase of high-rise buildings and the dense distribution of buildings, the planting of plants on the exterior walls of buildings is inevitable. [0003] my country's p...

AI Technical Summary

Problems solved by technology

[0006] 1. Since a single water pump is used to supply water to multi-layer water pipes, it is often difficult to evenly irrigate the plants on the outer walls of high-rise buildings because the water pressure is too high or too low, so that some plants absorb too much or too little water, which affects the health of plants. growth and development

[0007] 2. Clean up the impurities in the water through purifiers and filtering devices. In the outer layer of high buildings, the impurities that have been cleaned for a long time often contain nutrients and soil inside the green plants, and the cleaned impurities cannot be replenished outside the building. wall plant
