The building roof rainwater is collected the system that utilizes again
(1) technical field
The utility model relates to rainwater and collects the system that utilizes again, and particularly a kind of building roof rainwater is collected the system that utilizes again.
(2) background technology
The building roof rain water collecting system is a kind of by collecting the technology that is reused after rainwater process simple precipitation, the filtration treatment, water used during rainwater after the processing can be used as, as toilet flushing, pouring greenery patches, spray the road surface or recharge undergroundly, realize the zero-emission of rainwater.For the area that water resource relatively lacks, can increase and can utilize water resources quantity, alleviation water shortage status, avoid rainwater and sewage to associate with an evil person simultaneously, from pressure and the burden that has reduced sewerage treatment.
But rain water collecting system exists the rainwater collection efficiency low at present, the problem that rainwater is secondary polluted easily.
(3) summary of the invention
The technical problems to be solved in the utility model has provided a kind of rainwater collection efficiency height, and rainwater is not easy contaminated building roof rainwater and collects the system that utilizes again.
In order to solve the problems of the technologies described above, the utility model is realized by following measure: a kind of building roofing rainwater is collected the system that utilizes again, comprise the gutter that is located on the building roof, roof drain, storm sewer and rainwater treatment facility are as sedimentation basin, filtering ponds with the reservoir of water pump is housed.
Sedimentation basin described in the utility model and filtering ponds can be handled rainwater, prevent the secondary pollution of rainwater.
Storm sewer described in the utility model comprises tube connector, hanging pipe, and soil stack, described pipeline comprise subsoil drain and underground connecting pipe; Described tube connector one end is connected with roof drain, and the other end is connected with hanging pipe; Described soil stack one end is connected with hanging pipe, and the other end is connected to sedimentation basin, and filtering ponds link to each other by underground pipeline with reservoir.
The beneficial effects of the utility model:
1. roof drain can be collected the rainwater on building top, and rainwater flows into sedimentation basin by gutter, through can be used for the reuse of directions such as irrigating, afforest, flush the toilet behind the filter tank, has made full use of rainwater resource again, has reduced the consumption of tap water.
2. once drop into, can collect rainwater resource and utilization again, in case build up, operation does not account for the soil automatically, long-term mechanism is set up in phreatic supply, effectively the continuous sedimentation of control urban ground has developed the unconventional water source-rainwater in city, simultaneously, can also play partly flood diversion effect when heavy rain takes place, reduce the city waterlogging.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a scheme of installation of the present utility model.
1 roof drain among the figure, 2 gutters, 3 soil stacks, 4 subsoil drains, 5 collecting-tanks, 6 underground connecting pipes, 7 sedimentation basins, 8 filtering ponds, 9 water pumps, 10 user sides, 11 buildings, 12 reservoirs, 13 tube connectors, 14 hanging pipes, A is indoor, the outdoor ground line of B.
(5) specific embodiment
A kind of building roof rainwater is collected the system that utilizes again shown in Fig. 1 .2, comprise the gutter 2 that is located on building 11 roofings, at least one is installed in the roof drain 1 that is used to collect gutter 2 rainwater that is positioned at gutter 2 and storm sewer intersection on the building roof, with and the collecting-tank 5 that connects by pipeline successively of subordinate, sedimentation basin 7, filtering ponds 8 and the reservoir 12 that water pump 9 is housed.
Storm sewer comprises tube connector 13 as described in shown in Fig. 1 .2, hanging pipe 14, and soil stack 3, described pipeline comprise subsoil drain 4 and underground connecting pipe 6; Described tube connector 13 1 ends link to each other with roof drain 1, and the other end is connected with hanging pipe 14; Described soil stack 3 one ends are connected with hanging pipe 14, the other end and subsoil drain 4, described subsoil drain 4 other ends and collecting-tank 5; Collecting-tank 5, sedimentation basin 7 filters reservoir 8, and reservoir 12 links to each other by underground connecting pipe 6 with user side 10.
Tube connector 13 during installation, and hanging pipe 14 and soil stack 3 are positioned at indoor A, collecting-tank 5, and sedimentation basin 7 filters reservoir 8 and reservoir 12 and is positioned at below the outdoor ground line B.
The utility model operating principle is: rainwater catchments through roof drain 1 and flows into sedimentation basin 7 through precipitation through pipeline, and filtering ponds 8 filter the back and store by reservoir 12, promotes by water pump 9 at last and flows to each user side reuse.
