Greening drainage device

Abstract

The invention provides a greening drainage device. The greening drainage device comprises a thermal insulation board, water absorption cotton, water absorption cotton positioning grooves, a rainwatercollecting pipe, a water storage bucket, a water pump and water stop sheets, wherein a drain board is of a rectangular plate-like structure, multiple water absorption cotton fixing grooves are formedin bottoms of trapezoidal drainage grooves which are formed at the top of the drain board; one end of a water inlet pipe is divided into thirteen parts, and the other end of the water inlet pipe is communicated with the water pump; a rainwater collecting tank is mounted at the bottom of the drain board; a lawn fixing frame is mounted on the end surface of the top of the drain board. According to the greening drainage device, rainwater accumulated from rainfall is drained into the rainwater collecting tank from the trapezoidal drainage grooves for rainwater storage, and water waste caused by rainfall loss is avoided; furthermore, under matching with the water pump, when rainfall is less, the rainwater stored in the earlier stage can be conveyed into the trapezoidal drainage grooves again through the water inlet pipe and conveniently absorbed by roots of green lawn, and the phenomenon that greening attractiveness is affected due to the fact that the lawn is withered and yellow because ofinternal dewatering of the lawn is eliminated.

Description

technical field [0001] The invention belongs to the technical field of roof greening technology, in particular to a greening drainage device. Background technique [0002] Greening can improve environmental sanitation and play a variety of roles in maintaining ecological balance. At present, the greening work on the roof of the house mostly uses green plants such as lawns, which are directly laid. The amount of work is large, and the laying time is long. The lawn is prone to drying and yellowing, which affects the aesthetics of the green lake. [0003] Based on the above, the inventors found that the same existing greening invention, such as the Chinese invention application No. 200710030011.4, mentioned wall greening board and wall greening device, the wall greening board has a board; . The plate body has a rigid body layer, one side of the rigid body layer is provided with a water storage layer and a plant growth layer in sequence, and a protective fixed net layer is pro...

Problems solved by technology

[0008] In order to solve the above-mentioned technical problems, the present invention provides a greening drainage device to solve the problem that the existing water resource consumption is relatively large, water resources are easily wasted, and it is difficult to replace green plants, resulting in increased work for staff and affecting work efficiency. The external precipitation collection ability is poor, and the effect of precipitation recycling cannot be achieved, and the heat insulation ability of the roof of the house is weak, and the external heat is easily transferred to the interior of the room, causing the temperature to rise and affecting the normal life of personnel.
