Abstract
The invention discloses a water-saving drainage system for a roof. The water-saving drainage system comprises a main drainage pipeline, an intercepting plug, pumping equipment, a pumping pipeline and a branch drainage pipeline, the top of the main drainage pipeline is connected with a roof drainage outlet, the main drainage pipeline is used for draining roof rainwater to the ground, the intercepting plug is located in the main drainage pipeline and used for intercepting the rainwater drained by the main drainage pipeline, the pumping equipment and the pumping pipeline are used for pumping the rainwater intercepted by the intercepting plug to the roof, two ends of the branch drainage pipeline are butted with the main drainage pipeline, and the branch drainage pipeline is used for draining excessive accumulated water in a bypass after the intercepted rainwater in the main drainage pipeline exceeds a certain water storage height. The purpose of realizing water-saving drainage of the roof is realized.
Description
Technical field
The invention belongs to roof water saving discharge structure component technology field, particularly a kind of water-saving and water-draining system.
Background technology
Along with the raising of people's living standard, construction of city afforestation, increases City Green area coverage, improves human settlement environment in city, will more and more be subject to government department and numerous townsfolks' great attention.Due to a large amount of Construction of highrise buildings in city, leave over limited space, roof greening is also the important way that overcomes problems, increases City Green area coverage.In a lot of developed countries, on roof, afforest, beautify the environment, reduce pollution, build hanging garden, become the theme of New Times construction of city afforestation.
As everyone knows, China's water resource quite lacks, and along with the quickening of urbanization paces, a lot of big and medium-sized cities all face the problem of water supply gets, therefore solve the required water source of roof greening, are important difficult problems.On roof, afforest, utilize existing roof condition, can exist certain limitation: when rainfall is plentiful, while particularly raining in torrents, roof is not easy to get rid of unnecessary water, and cause roof infiltration; When rainwater is fewer, the enough water yields of easily collecting, easily do not cause arid, affect roof greening plant growth.And carry out pumping irrigation by city tap-water system, and can waste a large amount of source of clean water and the energy, more increased urban water use burden.For this reason, the present invention proposes the technical scheme of roof rain water being collected, facilitated roof crop irrigation.
Summary of the invention
The object of the invention is to realize a kind of roof water-saving and water-draining system, improve the ponding utilization rate of existing roof rain water, save the energy that draws water.A kind of water-saving and water-draining system of the present invention comprises:
Draining main flow pipeline, hangs over the pipeline on wall under roof, for discharging earthward roof rain water;
The plug that dams, dams for the rainwater that described draining main flow pipeline is discharged;
Pumping equipment and pumping conduit, the rainwater damming for the plug that dams described in handle is extracted into the water storage container on roof;
Water storage container, draws up next rainwater for accepting pumping equipment;
Draining tributary pipeline, and described draining main flow pipeline docking, surpass after certain retaining height for the rainwater when trapped draining main flow pipeline in, the discharge of detouring of the unnecessary ponding of confession.
Preferably, described in the plug that dams, and draining main flow pipeline can be integrated, and also can put in draining main flow pipeline adjusted position, for adjust retaining height according to the pumping rate of described pumping equipment.
By as mentioned above, the present invention has realized the roof ponding function of low energy consumption under not affecting large rainfall situation in draining.
Accompanying drawing explanation
Fig. 1 is a kind of water-saving and water-draining system structural representation of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.As shown in Figure 1.
A kind of water-saving and water-draining system of the present invention comprises: draining main flow pipeline 1, draining tributary pipeline 2, plug 3, pumping equipment 4 and pumping conduit 5 dam.
Wherein, draining main flow pipeline 1 is to hang over the pipeline on wall under roof, and it docks with roof drain, for discharging earthward roof rain water.Dam plug 3 for the rainwater of draining main flow pipeline 1 discharge is dammed.Pumping equipment 4 and pumping conduit 5, for the rainwater being dammed by the plug that dams is extracted into the roof water storage container 6 docking with pumping conduit, utilize.Draining tributary pipeline 2, its upper and lower side and draining main flow pipeline 1, embed in draining main flow pipeline 1, for the rainwater in trapped draining main flow pipeline 1, surpasses after certain retaining height, unnecessary water shunting out, continue discharge from draining main flow pipeline 1 after detouring.
Dam plug and draining main flow pipeline 1 can be one, also can be separated, with screw and rubber cushion etc., fix.And can put in draining main flow pipeline adjusted position, for adjust retaining height according to factors such as the pumping rate of described pumping equipment, draining main flow pipeline pressure tolerances.
The present invention is by carrying out design improvement to daily roof drainage system, realized by the water receiving area on roof and realized retaining, when roof rain water amount is less, can collect substantially, due to the effect of draining tributary pipeline, the unnecessary rainwater not affecting in large rainfall situation discharges rapidly simultaneously.In addition, because shutoff position is very little from roof distance, saved the energy that draws water.
Claims (4)
1. a roof water-saving and water-draining system, is characterized in that, comprising:
Draining main flow pipeline, top is connected with roof drain, for discharging earthward roof rain water;
