The roof greening irrigation device comprises a greening area at the roof of a building (G), wherein a reservoir (10) is arranged at the bottom of the building (G), and the sewage pipe (8) of each house of the building (10) is collectively connected with the reservoir (10); a water pump (9) is connected with an irrigation pool (6) arranged at the roof through a pipeline (7), and a buoyancy sensor (5) is arranged in the irrigation pool (6) and is electrically connected with the start switch of the water pump (9); and the irrigation pool (6) is erected in the greening area (H) through a drip irrigation device which comprises a micro waterpump (4), a hose (3) and a plurality of drip irrigation nozzles (2) arranged on the hose (3). The utility model provides a water resources utilizing device for roof greening to achieve the purpose that greening plants at the high-rise roof are irrigated without expropriating water resources.
Description
(1) technical field
The utility model is a kind of use device of water resource, particularly relates to a kind of roof greening water resource that is used for and irrigates the device that utilizes.
(2) background technology
The rapid economic development in Shanghai, per capita green area to 2006 will reach 11.5 square metres the end of the year, but still more much lower than the Warsaw, POL that per capita green area is the highest in the world.Municipal government also developed the urban green space energetically in nearly 2 years, and the city green areas of average per-person share increase year by year.But because the soil is limited in the urban district, developing a greenery patches needs a large amount of expropriations of land, and it is more and more difficult to increase green coverage in the urban district.High building stands in great numbers in the urban district, and skyscraper is very many.Therefore, utilize the site area on the high buildings and large mansions of urban district to increase greening, do not lose and a kind ofly not only utilized idle area space, but also increased the good plan that greening improves people's living conditions and environment.
Greening, plantation plant are to be unable to do without water, yet water is human and all biological indispensable important substance of depending on for existence, also be the irreplaceable very valuable natural resources of industrial and agricultural production, economic development and enhancement of environment, same soil, the energy etc. constitute the primary condition of human economy and social development.Development and national economy and human living standard's raising significantly is subjected to the restriction of water resource state.For a long time, because the shortage of serious ecology, environmental hazard and the water resource that unreasonable development and utilization caused of water resource, more and more be subjected to the extensive concern of international water resource and environmental area.
Relatively abundant on China freshwater resources surface, belong to abundance of water country.But China's population cardinal sum arable area radix is big, with relative being much smaller of the average water resources quantity of per hectare land area, stipulates 1700m per capita according to the United Nations per capita
3Be serious water shortage line, 1000m per capita
3Minimum for survival standard, China has been in serious lack of water edge, China have at present 15 provinces per capita the water yield be lower than the serious water shortage line.Shortage of water resources, imbalance between supply and demand are outstanding, the seriously polluted restriction of water China's water resources development and utilization and national economy sustainable development.
Based on the present situation that water resource faced, development trend from future, because society constantly increases the demand of water, and the available water resource that natural world can provide has certain limit, outstanding imbalance between supply and demand makes water resource become the important restraining factors of the national economic development.Be accompanied by becoming increasingly conspicuous of water resources problems; the key of water resource utilization and protection is the correct evaluation of water resource quantity and quality; effective enforcement of the rational deployment of the reasonable analysis of the equilibrium of supply and demand, water resources development and utilization engineering, water-saving technology and measure; realization prevents, controls and administer water and pollutes; alleviate the pressure of shortage of water resources, realize effective protection, sustainable utilization and the benign cycle of water resource.
Rational development of water resources utilizes, and effectively protection is to keep sustainable utilization of water resource with management, realizes the eucyclic principal security of water resource, also is to keep social progress, the key point of national economy sustainable development.
Add up according to investigations, Berlin, Germany has been built first ecological building.Except that other facility, be provided with water receiver on the roof, the rainwater of collecting and storing with its waters the meadow on roof, and the water that permeates down from the meadow is got back to holder again, flows to each lavatory flushing toilet of building then.Weather around the meadow of roof and the water receiver energy minor betterment building reduces the temperature fluctuation in the building.
This method has solved a certain amount of green area irrigation water.But facts have proved that the water yield that only relies on rainfall is to be not enough to provide and to keep plant growing institute water requirement, especially the roof greening soil horizon is thinner, and the soil moisture conservation water retention capacity is relatively poor, and only rainwater can not keep plant normal growth.People had both wished that the vegetation on the roof flourished, and the effect of play protection, beautifying the environment does not wish that again roof plant and people strive water, the water resource of consume valuable.
(3) utility model content
The purpose of this utility model provides roof greening water resource use device, makes both to have reached the irrigation Green Roof Plants, does not encroach on the purpose of water resource again.
The purpose of this utility model is solved by following technical scheme:
A kind of roof greening irrigation device comprises the greening on roof, building, it is characterized in that:
In the bottom in building one cistern is set, concentrates by the downcomer at each family, building to connect cistern;
Connect the pond of pouring water that is arranged on the roof by the road by suction pump;
In the described pond of pouring water, the buoyancy sensor is set, is electrically connected the starting switch of suction pump.
The pond of pouring water is erected in the greening through flexible pipe and drip irrigation appliance.
Described drip irrigation appliance for by micro pump through flexible pipe and be installed in most drip irrigation shower nozzles on the flexible pipe.
The starting switch of described micro pump is electrically connected with humidity sensor in being embedded in greening.
The pressure of described micro pump is 0.2 to 0.5 kg/cm.
Porch at described suction pump or micro pump is provided with screen pack respectively.
The beneficial effects of the utility model: adopt the technical program, plant landscape on the roof, building is except that the water of accepting natural precipitation, by the humidity sensor monitoring soil moisture that is embedded in the soil, when needs are irrigated, open micro pump, starting drip irrigation appliance pours water to plant, the water of system all comes from the sanitary sewage that the building produces, with water pumper the water in the cistern is extracted on the big roof step by step again, through being conducting to the cistern on the roof after the filter screen preliminary purification, come the green plants on the enlarging flooring is irrigated, the water yield in the buoyancy sensor monitoring pool in the cistern, whether the decision suction pump starts.
The technical program implementation procedure can be progressively to reconstruct the old building in existing city, on the basic structure basis of invariable of building, the building flooring is extended, plantation greening on the flooring of enlarging, make that these greenings can normal growth, so both increase city's green areas, do not taken the land area of too much inner city again.Can the unified planning design-build when newly-built building.
