The building housetop greening device
Technical field
The utility model relates to that a kind of surface construction forms on the roof of building can be used for planting and various green plants and guarantee the building housetop greening device that green plants can not thirst because of lack of water.
Background technology
On the building roof, plant the greenbelt that various green plants can increase the city at present, guarantee that urban air is fresh, and can give the cooling roof above the building, thereby guarantee that building upper strata resident reduces extremely hot that the sun is exposed to the sun and causes in summer.But these roof Architectural Equipments are often watered because of the green plants of a large amount of irrigation waters of needs to its plantation, thereby cause cost up, the complex structure of roof greening Architectural Equipment, the roof greening Architectural Equipment that also has lacks irrigating facility, usually causes thirsting of Green Roof Plants.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of can be automatically to the irrigation of watering of the green plants of roof planting, guarantee the building housetop greening device that green plants can not thirst because of lack of water.
The purpose of this utility model is achieved in that and comprises the planting groove of planting various green plants, it is characterized in that: described planting groove is a kind of cell body that has water cavity, in cell body, plant and be implanted with green plants, be provided with through hole between water cavity and the cell body, in this through hole, check valve is installed.
The installation direction of described check valve is for guaranteeing that water can only be left in the water cavity from cell body, and the described spherome surface that is arranged on the check valve on the check valve passage has the aquaporin that can permeate moisture content.
Described water cavity is connected with the header tank that is arranged on above the building roof, and header tank is connected by magnetic valve and water supply pipe.
Funnelform rainwater water butt also is installed on the building roof, and rainwater water butt and header tank are connected.
Between the water cavity of planting groove and the external world overflow pipe is installed, the height of overflow pipe is higher than the height of header tank.
The utility model can be automatically to the irrigation of watering of the green plants of roof planting, guarantee the advantage that green plants can not thirst because of lack of water.

Fig. 1 is the structural representation of utility model.
Specific implementation method
As shown in Figure 1, the utility model comprises the planting groove 1 of planting green plants, it is characterized in that: described planting groove 1 is a kind of cell body 3 that has water cavity 2, plants in cell body 3 and is implanted with green plants, be provided with through hole between water cavity 2 and the cell body 3, check valve 4 is installed in this through hole.
The installation direction of described check valve 4 is for guaranteeing that water can only be left in the water cavity 2 from cell body 3, and this structure guarantees that the water in the water cavity 2 can not be punched in the cell body 3.The described spherome surface that is arranged on the check valve 4 on the check valve passage has the aquaporin that can permeate moisture content, this structure guarantees that the water in the water cavity 2 enters into the soil of cell body 3 by the mode of infiltration, moisture content is arranged all the time at the soil bottom that has so just guaranteed cell body 3, and is withered thereby the assurance green plants absorbs water from the cell body bottom.
Described water cavity 2 is connected with the header tank 5 that is arranged on above the building roof, and header tank 5 is connected by magnetic valve 6 and water supply pipe.While magnetic valve 6 also can be used in the valve that is provided with ball float control in the header tank 5 and replace, and guarantee has water in the header tank 5 always.
Funnelform rainwater water butt 7 also is installed on the building roof, and rainwater water butt 7 is connected with header tank 5.Funnelform rainwater water butt 7 is delivered in the header tank 5 after rainwater is collected, thereby reaches water-saving purpose.
Between the water cavity 2 of planting groove 1 and the external world overflow pipe 8 is installed, the height of overflow pipe 8 is higher than the height of header tank 5.When being discharged to the outside in the water cavity 2 during dilutional hyponatremia.
