Embodiment Construction

[0011] Such as Figure 1~4 As shown, the green roof is fixed on the original roof 6 through the hydraulic device 3 and the linkage mechanism 4, and the inclination angle of the roof can be adjusted, and the gap at the roof ridge is covered with a foldable elastic rain cloth 5; the photovoltaic solar power generation device 1 is fixed on the surface of the vegetation layer 7, as The whole system provides electric energy; the rainwater collection device 2 filters and collects the rainwater discharged from the drainage layer 12, the vegetation layer and the matrix layer 10, and recycles or discharges it to the underground pipe network.

[0012] When the rainwater falls to the vegetation layer 7, part of the rainwater is absorbed and stored by the vegetation layer and the matrix layer 8; part of the rainwater passes through the isolation filter layer 9 and reaches the drainage layer 10. Due to the height difference between the two ends of the drainage channel 18, under the action of...

Abstract

The invention provides a system having the functions of urban surface runoff regulation and indoor temperature control. The system comprises a vegetation layer, a matrix layer, an isolation filter layer, a water draining layer, a moisture preserving carpet, a root blocking layer, a waterproof layer, a structural layer, a hydraulic drive device, a connecting rod mechanism, foldable elastic waterproof cloth, a photovoltaic solar power generating system and a rainwater collecting device. By the adoption of the technical scheme and the grooving design of the water draining layer, rainwater form pipeline type circulation in the water draining layer under the gravitational effect. By adjusting a roof angle, on the one hand, the rainwater absorbing and storage capability of the vegetation layer and the matrix layer is improved, the water circulating rate of the water draining layer is reduced, and the surface runoff is decreased; on the other hand, the surface air flowing strength of a roof and the vegetation layer are changed, further heat dissipation speed is further changed, and indoor temperature is regulated. The system gives consideration to the indoor temperature while regulating the surface runoff, improves an ecological value of the roof per unit area and achieves win-win social, economic and environmental benefits.

Description

technical field [0001] The invention belongs to the fields of urban environment planning, urban flood control and green building, and in particular relates to a system with the functions of urban surface runoff regulation and indoor temperature control. Background technique [0002] The traditional urban construction model is extensive and destructive. After the city is built, the surface runoff increases significantly. Roof runoff is the direct source of building rainwater runoff. Scientific and effective management of rainwater falling on roofs can reduce urban surface rainwater runoff, thereby reducing the load on urban water supply and drainage facilities and sewage treatment facilities, which is the key to realizing green roofs. As an indispensable engineering facility in green buildings, green roofs have important ecological significance. It can realize roof landscape greening through vegetation planting, and at the same time realize the purification, storage and resou...
