Roof greening system for energy-saving building

Abstract

The invention relates to an energy-saving building, in particular to a roof greening system for the energy-saving building. The roof greening system comprises a green plant planting module, an irrigation module and an anti-seepage module; the green plant planting module comprises a green plant layer, a planting layer, a filter layer and a water storage and drainage layer which are sequentially arranged from top to bottom; the irrigation module comprises a water pump, a pipeline and a spray head, the spray head comprises a connecting pipe used for being connected to the pipeline, a spray cap isarranged at the upper end of the connecting pipe, a plurality of vertical water spray openings are evenly formed in the spray cap, a height-adjustable water retaining cap is arranged at the upper endof the spray cap, and the water retaining cap is in a downward hemisphere shape; and the anti-seepage module is arranged between the green plant planting module and a roof and comprises a root separating layer, a first anti-seepage layer, a drying layer, a second anti-seepage layer and a cushion layer which are sequentially arranged from top to bottom, a water removing device is arranged in the drying layer and comprises two electric leads, a power source is connected between the two electric leads, the electric leads are connected with a plurality of conductive wires, and the conductive wires of the two conductive leads are distributed in a staggered manner, so that the sprinkling irrigation effect can be effectively controlled.

Description

technical field [0001] The invention relates to energy-saving buildings, in particular to a roof greening system for energy-saving buildings. Background technique [0002] Energy-saving buildings refer to the low-energy buildings designed after the study of building planning zoning, groups and individual units, building orientation, distance, solar radiation, wind direction and external space environment in accordance with the basic methods of climate design and energy conservation. Its main indicators There are: architectural planning and layout should be conducive to natural ventilation, and the greening rate should not be lower than 35%; building spacing should ensure that each household has at least one living space that can receive full window sunlight for 2 hours on a severe cold day, etc. [0003] In order to realize energy-saving buildings, technicians in the field have extensively studied the energy-saving of environmental control, the utilization of clean resources...

AI Technical Summary

Problems solved by technology

[0004] There are two main methods for existing roof greening. One is to place flower pots on the roof, and the other is to lay planting base on the roof for planting. The method of placing flower pots on the roof is low in cost, but it is troublesome to water. , and the survival rate is low, the planting base is laid on the roof, the watering is convenient, the planting area is large, and it is widely used

[0005] The current planting-based roof greening system mainly includes the green plant layer and the planting base, which are irrigated by sprinkler irrigation or drip irrigation. Irrigation by drip irrigation cannot remove the dust on the surface of the plants very well, and the effect of fertilization is poor. Spray irrigation is used. Irrigation can remove the dust on the surface of plants very well and fertilize evenly. However, due to the sprinkler irrigation on the roof, it is easy to produce splashes and affect the residents.
