The roof afforestation rainwater collection and drip irrigation device is simple in structure, practicable and convenient, and integrates rainwater collection, rainwater storage and drip irrigation, nature rainfall is effectively utilized, water resource waste is reduced, manual watering and irrigation management links are reduced, and roof afforestation cost is lowered.

Description

A kind of roof greening rainwater collection and drip irrigation appliance
Technical field
The utility model relates to roof greening field, is specially a kind of roof greening rainwater collection and drip irrigation appliance.
Background technology
China is the country of a shortage of water resources, water resources ownership per capita comes 109, the world, it is only 1/4th of world average level, united state classifies one of 13 poor-water countries in the world as, and agricultural water accounts for 70% left and right of national total water amount, and China is as large agricultural country, carry out rainwater shortage technology very important.。Water is one of key factor of restriction roof greening development, and particularly whether northern China water-deficient area development roof greening moisture abundance has determined its success or failure.Northern China rainfall concentrates on 7-9 month, often with heavy rain or heavy rain form, occurs, is difficult to utilize; Evaporation capacity is but up to more than 2000mm.
Utility model content
Of the present utility model objectjust be to provide a kind of roof greening rainwater collection and drip irrigation appliance, the utility model is a kind of simple in structure, practical and convenient rainwater-collecting, storage, drip irrigation device of integrating.It has effectively utilized natural precipitation, has reduced water resources consumption, has reduced again manual watering's management link simultaneously, has reduced roof greening cost
Of the present utility model technical schemefor:
A kind of roof greening rainwater collection of the utility model and drip irrigation appliance, it comprises device for collecting rain water, it is characterized in that: in device for collecting rain water upper end, be provided with the opening that accesses the pipe that rains, in device for collecting rain water upper end, be also provided with overfall gap, in device for collecting rain water lower end, be connected with drip irrigation pipe.
Drip irrigation pipe described in the utility model is connected on the delivery port of device for collecting rain water lower end setting by valve and strainer, is connected with to put to be connected to drip head in drip irrigation pipe.
The volume setting of device for collecting rain water described in the utility model is controlled in 150L.
At the utility model, at the pipe 1 that rains, be provided with screen pack with device for collecting rain water 2 junctions.
Of the present utility model beneficial effectfor: design main points of the present utility model are to utilize collector to collect rainwater, and rainwater enters droping irrigating pipe after filtering by collector lower end water pipe, by siphonage, is transported in plant soil.The utility model is a kind of simple in structure, practical and convenient rainwater-collecting, storage, drip irrigation device of integrating.It has effectively utilized natural precipitation, has reduced water resources consumption, has reduced again manual watering's management link simultaneously, has reduced roof greening cost.
Rainwater catchment system be realize Rainwater Resources, using water wisely, self-restraint underground water, reduce room pollution of area source, alleviate city flood and drainage system pressure, be the important means of improving and repairing Urban Water Environment.Along with economic develop rapidly and the quickening of urbanization process, the deficient problem of freshwater resources is more outstanding, rainwater catchment system has wide development space, has become and has alleviated shortage of water resources, reduces the harm of rain flood, improved one of Important Action of water reuse rate.
Roof greening is that an ecological feasible approach has been opened up in urban rainwater collection, is a kind of run-off, pollution abatement and urban heat land effect of subduing, and reconciles the important form of building temperature and beautifying city.Collection utilizes rainwater to supply with for roof greening provides moisture, realizes rain water reuse, reduces the waste of water resource, alleviates the present situation of city water resource shortage, effectively reduces roof greening cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of roof greening rainwater collection of the utility model embodiment and drip irrigation appliance as shown in Figure 1, it comprises device for collecting rain water 2, in device for collecting rain water 2 upper ends, be provided with the opening 3 that accesses the pipe 1 that rains, in device for collecting rain water 2 upper ends, be also provided with overfall gap 4, in device for collecting rain water 2 lower ends, be connected with drip irrigation pipe 8.Described drip irrigation pipe 8 is connected on the delivery port 5 of device for collecting rain water 2 lower ends settings by valve 6 and strainer 7, is connected with to put to be connected to drip head 9 in drip irrigation pipe 8.Raining, pipe 1 also can arrange a screen pack with device for collecting rain water 2 junctions.
During use, the rainfall of roof lookout terrace is collected in device for collecting rain water 2, open valve 6 during Green Roof Plants lack of water, collected rainwater flows automatically in droping irrigating pipe 8 by strainer 7, then splashes in plant cultivation media by drip irrigation pipe 8.
Because considering roof load-bearing problem, device for collecting rain water 2 volumes should be controlled in 150L, excessive for fear of amount of precipitation, in device for collecting rain water 2 upper ends, overfall gap is set, unnecessary rainfall is got rid of, consider that foreign material in lookout terrace rainwater, impurity are more, need periodic cleaning to be arranged on to rain the foreign material on screen pack that pipe 1 and device for collecting rain water 2 junctions arrange, and the foreign material in periodic cleaning discharge filter 7.
