Automatic irrigation type water-retaining and water-cleaning green roof system based on solar energy

Abstract

The invention discloses an automatic irrigation type water-retaining and water-cleaning green roof system based on solar energy. The system comprises a solar energy storage and supply assembly, a light green roof, an automatic drip irrigation assembly and a water storage tank; a plastic drainage plate, geotextile, an artificial matrix and sedum lineare are on the light green roof from a building roof; the artificial matrix is formed by mixing perlite and organic chicken manure; the water storage tank is installed in a staircase on the inner top layer of a building body, and used for receivingrainwater drained by the light green roof; an overflow hole is formed in the water storage tank; the solar energy storage and supply assembly comprises a solar panel, a charging controller and a storage battery; the automatic drip irrigation assembly comprises a drip irrigation pipeline, a moisture detector, a water pump and a drip irrigation controller; the drip irrigation controller controls thewater pump to be started and stopped according to the moisture content in the artificial matrix; and the automatic drip irrigation purpose is achieved. By means of the automatic irrigation type water-retaining and water-cleaning green roof system based on solar energy in the invention, the risk of non-point source pollution is reduced while the intercepting rate of the green roof in the rain period is increased; the survival of plants on the green roof in the drought period can be enhanced; and the ecological environment benefit of the green roof is ensured.

Description

technical field [0001] The invention belongs to the field of construction, and relates to roof greening, intelligent irrigation, and energy-saving water purification technology, in particular to a solar energy-based automatic irrigation type green roof system for water retention and cleanliness. Background technique [0002] A green roof can be simply defined as "vegetated cover placed over a man-made structure". The construction of early green roofs was mainly to meet people's aesthetic needs, while modern green roofs can also take into account environmental benefits in addition to pure aesthetic functions. A modern green roof is the deliberate placement of multiple layers of construction beneath a planting and planting substrate to form an integrated structure. Most green roofs have a similar structure, which is in direct contact with the roof panel. From the roof panel, the construction layers are: waterproof layer, drainage layer, filter layer, planting substrate layer ...
