Description
Technical field
The utility model is related to a kind of rainwater-collecting tanks for building rain falling pipe end, belong to construction drainage engineering
Field, more particularly, to a kind of building roof rain water collecting system.
Background technology
According to " General Office of the State Council is about the instruction for promoting sponge urban construction ", it is proposed that China is built in sponge city
If overall goal, i.e., " by sponge urban construction, it is comprehensive take ooze, be stagnant, storing, net, use, the measures such as row, subtract to the maximum extent
Few influence of the city development construction to ecological environment, by 70% rainfall on-site elimination and utilization ".
Rain water on roof is collected using one of the important measures for being sponge urban construction, while also having larger economy
Value, it is particularly advantageous to alleviate the short water supply situation that water resource lacks area." sponge urban construction technical manual " is pointed out
" water shortage zone, which is contemplated that, preferentially to carry out rain water on roof to harvest reuse ... ... rainwater storage facility is in combination with live feelings
Condition selects the facilities such as rainwater tank, ground or underground conservation pool." existing rainwater catchment system facility, equipment, some structures are multiple
Miscellaneous, difficult in maintenance, some need electric drive, consuming energy, operational management difficulty is big, is difficult to promote on a large scale.
Invention content
The purpose of this utility model is to provide a kind of rainwater-collecting tank for building rain falling pipe end, to solve
The problem of building roofing rainwater catchment system.
The utility model is realized by following technology：The rainwater-collecting for building rain falling pipe end
Tank, including early-stage rainwater stream abandoning tank 1, rainwater-collecting tank 2, floating ball 3, position-limiting tube 4, pure water pipe 5, drainpipe 6, overflow pipe 7, holder
8, rain falling pipe 9, rainwater-collecting tank water inlet pipe 10, permeable hole 11, cylindrical type plastic foam 12, wherein 3 diameter of floating ball is bigger
In the caliber of rain falling pipe 9,4 caliber of position-limiting tube is slightly larger than 3 diameter of floating ball, and 3 bottom of floating ball is bonded cylindrical type plastic foam 12,
For increasing buoyancy, it is 1 ~ 3 times of 3 diameter of floating ball to keep the stability of lifting process, 12 height of cylindrical type plastic foam, limit
Distance is equal to 12 height of cylindrical type plastic foam between 1 bottom of 4 lower end of pipe and early-stage rainwater stream abandoning tank, and position-limiting tube 4 is provided with permeable
Hole 11,11 diameter of permeable hole should be greater than 1cm, and 11 gross area of permeable hole should be greater than the half of 4 surface area of position-limiting tube, ensure limit
The water permeable ability of position pipe 4.
The volume of water pot according to " General Office of the State Council about promote sponge urban construction instruction " control targe
It is required that and the formula calculating acquirement in " building and cell rainwater utilization project technical specification ".Early-stage rainwater stream abandoning amount V1=roofing
Abandoned stream runoff thickness δ × roofing catchment area F, roofing abandoned stream runoff thickness δ use 2 ~ 3mm.Rainwater-collecting moisture storage capacity V2=sponge
The instruction of urban construction requires rainfall × roofing catchment area F that 70% on-site elimination utilizes.
The utility model has the beneficial effects that it is simple in structure, it is easy to maintain convenient for making and installing；It being capable of abandoned stream initial stage rain
Water effectively collects the cleaner rainwater utilization of water quality；Overall cost is cheap, application easy to spread.

Specific implementation mode
The utility model is by early-stage rainwater stream abandoning tank 1, rainwater-collecting tank 2, floating ball 3, position-limiting tube 4, pure water pipe 5, drainpipe
6, overflow pipe 7, holder 8, rain falling pipe 9, rainwater-collecting tank water inlet pipe 10, permeable hole 11, cylindrical type plastic foam 12, wherein
3 diameter of floating ball is slightly larger than the caliber of rain falling pipe 9, and 4 caliber of position-limiting tube is slightly larger than 3 diameter of floating ball, and 3 bottom of floating ball is bonded cylinder
Shape strand foam 12, for increasing buoyancy, it is that floating ball 3 is straight to keep the stability of lifting process, 12 height of cylindrical type plastic foam
1 ~ 3 times of diameter, distance is equal to 12 height of cylindrical type plastic foam, limit between 1 bottom of 4 lower end of position-limiting tube and early-stage rainwater stream abandoning tank
Position pipe 4 is provided with permeable hole 11, and 11 diameter of permeable hole should be greater than 1cm, and 11 gross area of permeable hole should be greater than the two of 4 surface area of position-limiting tube
/ mono-, ensure the water permeable ability of position-limiting tube 4.Stainless steel making can be used in floating ball 3, to improve service life.
The volume of water pot according to " General Office of the State Council about promote sponge urban construction instruction " control targe
It is required that and the formula calculating acquirement in " building and cell rainwater utilization project technical specification ".Early-stage rainwater stream abandoning amount V1=roofing
Abandoned stream runoff thickness δ × roofing catchment area F, roofing abandoned stream runoff thickness δ use 2 ~ 3mm.Rainwater-collecting moisture storage capacity V2=sponge
The instruction of urban construction requires rainfall × roofing catchment area F that 70% on-site elimination utilizes.
Anhydrous in early-stage rainwater stream abandoning tank 1 when beginning to rain, floating ball 3 is located at 4 bottom of position-limiting tube.Wait for that initial rainwater flows into,
In early-stage rainwater stream abandoning tank 1 water level constantly increase hold up floating ball 3, when floating ball 3 by water buoyancy rise, closely withstand rain falling
The bottom obstruction rainwater of pipe 9 enters, and will enter rain along rainwater-collecting tank water inlet pipe 10 after making rainwater that can not flow into rain water drainage tank 1
Water collecting tank 2.If rainwater fills in rainwater-collecting tank 2, extra rainwater is drained along overflow pipe 7.After rain stops, initial rainwater is abandoned
Stream tank 1, which is discharged into sewage conduct by the emptying of drainpipe 6 and conveys sewage treatment plant's processing, waits for next rainfall, and floating ball 3 is in the early stage
Rain water drainage tank 1 drops back into 4 bottom of position-limiting tube after being vented.Rainwater recoverable in rainwater-collecting tank 2.
