Description
Technical field
The present invention relates to a kind of rainwater catchment system device, especially a kind of early-stage rainwater stream abandoning device.
Background technology
Because initial stage runoff rain drop erosion effect, initial stage runoff pollutant levels in the rain is higher, the water quality muddiness, and along with continuing of rainfall, in case scouring effect is finished, the water quality of runoff rainwater will obviously improve.Usually the rainwater collection mode that adopts is that the rainwater collection conduit is directly inserted the rainwater storage pool at present, not only with serious pollution early-stage rainwater is collected, also because the capacity limit of rainwater storage pool, on the contrary cleaner later stage stormwater overflow is emitted, causing increases the subsequent treatment difficulty.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, thus provide a kind of can abandoned stream in the rainwater collection process fall with serious pollution initial stage runoff rainwater, only collect cleaner runoff rainwater alleviate greatly the subsequent treatment structure burden, save the early-stage rainwater stream abandoning device of investment and operating cost.
According to technical scheme provided by the invention, described early-stage rainwater stream abandoning device, it comprises drainage tank, water-distributing well and abandoned stream device, water-distributing well is provided with the rainwater collecting pipe, first water side of water-distributing well connects the rainwater storage pool, be connected with communicating pipe on the drainage tank, second water side and the water inlet end of communicating pipe of water-distributing well are connected with the abandoned stream device, and the port of export of abandoned stream device is communicated with communicating pipe entrance point maintenance.
Described abandoned stream device comprises the housing of tubulose, and the upper end of housing is connected with the water inlet pipe that internal diameter dwindles than housing, and constraint has the ball float of intermittent shutoff water inlet pipe in housing, and the entrance point of abandoned stream device is lower than the inner chamber top of drainage tank.
Connection seat on communicating pipe, the housing bottom of described abandoned stream device closely is plugged in the mount pad, and has set up permeable carriage at the mount pad inwall of housing lower end, and the mount pad bottom was connected on communicating pipe.
Be provided with filter grid near the water-distributing well inwall of rainwater collecting pipe, the water inlet pipe of described abandoned stream device is connected on the water-distributing well wall body between first water side of filter grid and water-distributing well.
Link to each other by one section tube connector with positive taper between the housing of abandoned stream device and the water inlet pipe, and the ball float external diameter is greater than the entrance point of tube connector, the ball float external diameter is less than the port of export of tube connector.
The present invention is simple in structure, and convenient management can fall with serious pollution initial stage runoff rainwater by abandoned stream in the rainwater collection process, only collect cleaner runoff rainwater, thereby alleviate the burden of subsequent treatment structure greatly, saves investment and operating cost.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Fig. 2 is the abandoned stream device overall structure schematic diagram among the present invention.
Fig. 3 is A-A sectional view of Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: the present invention mainly is made of drainage tank 1, water-distributing well 2, rainwater collecting pipe 3, rainwater storage pool 4, communicating pipe 5, abandoned stream device 6, housing 6a, water inlet pipe 6b, ball float 6c, tube connector 6d, mount pad 6e, permeable carriage 6f and filtration graticule mesh 7 etc.
Early-stage rainwater stream abandoning device of the present invention, it comprises drainage tank 1, water-distributing well 2 and abandoned stream device 6, water-distributing well 1 is provided with rainwater collecting pipe 3, first water side of water-distributing well 2 connects rainwater storage pool 4, be connected with communicating pipe 5 on the drainage tank 1, second water side and the water inlet end of communicating pipe 5 of water-distributing well 2 are connected with abandoned stream device 6, the port of export of abandoned stream device 6 is communicated with communicating pipes 5 entrance point maintenance, described abandoned stream device 6 comprises the housing 6a of tubulose, the upper end of housing 6a is connected with the water inlet pipe 6b that internal diameter dwindles than housing 6a, constraint has the ball float 6c of intermittent shutoff water inlet pipe 6b in housing 6a, and the entrance point of abandoned stream device 6 is lower than the inner chamber top (peak level) of drainage tank 1.
Be provided with filter grid 7 near water-distributing well 2 inwalls of rainwater collecting pipe 3, the water inlet pipe 6b of described abandoned stream device 6 is connected on water-distributing well 2 wall bodies between first water side of filter grid 7 and water-distributing well 2.
Link to each other by one section tube connector 6d with positive taper between the housing 6a of abandoned stream device 6 and the water inlet pipe 6b, and ball float 6c external diameter is greater than the entrance point of tube connector 6d, ball float 6c external diameter is less than the port of export of tube connector 6d.
During use, the rainwater that flows into water-distributing wells 2 from rainwater collecting pipe 3 earlier through the lattice screen pack block 7 cut out bulky grain pollutant such as leaf after, flow in the drainage tank 1 by abandoned stream device 6 from water-distributing well 2, ball float 6c in abandoned stream 6 devices improves along with the water level in the drainage tank 1 and progressively rises, when ball float 6c also rises to abandoned stream device top, blocked the water inlet pipe 6b delivery port of abandoned stream device 1, water inlet pipe 6b delivery port is by after the shutoff, in, the runoff rainwater in later stage just changes its course and flows into rainwater storage pool 4, as utilizing the water source from now on again, thereby finish abandoned stream to serious pollution initial stage runoff rainwater.
Abandoned stream device 6 can dispose the number of abandoned stream device 6 by the inflow-rate of water turbine of maximum rainfall runoff amount of initial stage and abandoned stream device 6.The design capacity of drainage tank 1 is the abandoned stream amount of early-stage rainwater, and time-delay entered urban discharging pipeline after rain was adopted in discharging.
