The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of rain water drainage and treating apparatus comprise:
The first heavy chamber 5 that is connected with rainwater water inlet pipe 2;
By the two heavy chambers 9 that tube connector 10 is communicated with described just heavy chamber 5, described tube connector 10 is positioned at the middle part of described just heavy chamber 5;
The discharge structure that is communicated with described two heavy chambers 5.
Adopt device of the present utility model, rainwater at first enters just heavy chamber 5 by rainwater water inlet 2, finishes precipitation for the first time, when water level reaches tube connector 10 positions, can enter into two heavy chambers 9 by tube connector 10 and carry out the precipitation second time, the rainwater after finally purifying by the discharge structure discharge.Because tube connector 10 is positioned at the middle part of heavy chamber 5 just, the pollutant of part precipitation all can be deposited on the bottom of just heavy chamber 5 in the rainwater, and therefore the pollutant of the keeping afloat tube connector 10 of can not sailing can play effective catharsis.
In above-described embodiment of the present utility model, the described rainwater water inlet pipe 2 concrete float chambers 4 that pass through are communicated with described just heavy chamber 5; 4 are provided with ball float 11 in the described float chamber, its diameter is greater than the diameter of described rainwater water inlet pipe 2, when the rainwater of described rainwater water inlet pipe 2 inflows is greater than a thresholding in the unit interval (flow of rainwater water inlet pipe 2 is greater than the flow of gutter 13), the described rainwater water inlet pipe 2 of described ball float 11 sealings and just heavy chamber connector.
In above-described embodiment of the present utility model, described float chamber 4 is trapezoidal, and its minor face is communicated with described rainwater water inlet pipe 2, and its long limit is communicated with described just heavy chamber 5.Adopt the float chamber 4 of trapezium structure to play guide effect to ball float 11 well, be more conducive to seal rainwater water inlet pipe 2.
Preferably, in above-described embodiment of the present utility model, described ball float 11 is made by timber and/or north material, with reduction weight, thus easier floating on the surface, and the better effects if of sealing rainwater water inlet pipe 2.
In above-described embodiment of the present utility model, described discharge structure comprises:
The gutter 20 that is communicated with described two heavy chambers 16;
The bleed off pipe 22 that water inlet is connected with the delivery port of described gutter 20, the water inlet position of described bleed off pipe 22 is higher than the position of described gutter 20 water inlets;
Wherein, the water inlet of described bleed off pipe 22 also is connected with described rainwater water inlet pipe 2.
In the early stage in the rainwater processing procedure:
Rainwater enters just heavy chamber 5 by rainwater water inlet pipe 2, and bulky grain heavy pollutants such as silt are deposited on just heavy 5 bottoms, chamber, and bulky grain lightweight pollutants such as leaf float on the liquid level, and water level rises gradually.Before if water level arrives gutter 10 height, rainfall finishes, and at this moment, just retaining is whole initial stages to abandon rainfall in the heavy chamber 5, and degree of purification is low, is applicable to irrigation.
If amount of precipitation continues to increase, when water level rose to gutter 10 height, rainwater entered two heavy chambers 9 by gutter 10, and the granule heavy pollutant is deposited on two heavy 9 bottoms, chamber, and granule lightweight pollutant floats on the water surface, and water level rises gradually.If rainwater does not flow out from gutter 13, rainfall just finishes, and at this moment, just retaining is whole initial stages to abandon rainfall in heavy chamber 5 and the two heavy chambers 9.
In mid-term rainwater processing procedure:
If rainfall is proceeded, rainwater is then discharged from gutter 13.If in the unit interval, the rainwater that rainwater water inlet pipe 2 flows into is during less than certain thresholding, and rainwater is handled consistent with above-mentioned early-stage rainwater processing procedure.Its degree of purification of rainwater that discharge from gutter 13 this moment is the highest, can utilize at carwash or drinking water and handle in earlier stage.
In heavy rain or heavy rain process:
If in the unit interval, the rainwater that rainwater water inlet pipe 2 flows into is during greater than certain thresholding, just heavy chamber 5 middle water levels rise to the position of float chamber 4 gradually, ball float 11 raises under the rainwater buoyancy function gradually, the outlet of rainwater water inlet pipe 2 sealing the most at last, the rainwater that after this flows in the rainwater water inlet pipe 2 flows out through bleed off pipe 12.
Change moderate rain or light rain process at heavy rain or heavy rain:
If rainfall intensity reduces gradually, when the rainwater that rainwater water inlet pipe 2 flows into is lower than certain thresholding again, ball float 11 in the float chamber 4 reduces with water level and descends gradually, can stop draining in the bleed off pipe 12 gradually, and rainwater is after this handled consistent with above-mentioned early-stage rainwater processing procedure.
Concrete, in above-described embodiment of the present utility model, the bottom of described just heavy chamber 5 and described two heavy chambers 9 is equipped with mudhole 3 and atmospheric valve 8;
In the process after precipitation finishes:
Open atmospheric valve 8, the bottom rainwater in just heavy chamber 5 and the two heavy chambers 9 is emitted, the rainwater of emitting can be used for watering the courtyard economy crop.
After the rainwater emptying in just heavy chamber 5 and the two heavy chambers 9, open mudhole 3, the contaminant deposition in just heavy chamber 5 and the two heavy chambers 9 is discharged.
Because tube connector 10 diameters are crossed the pollutant that conference causes swimming in the water surface and flowed in the two heavy chambers 9, influence the quality of rainwater purification, preferably, in above-described embodiment of the present utility model, the diameter of described tube connector 10 is less than the diameter of described rainwater water inlet pipe 2.
In addition, in above-described embodiment of the present utility model, the top of described rainwater water inlet pipe 2 is provided with rain-harvesting trough 1; Wherein, the area of described rain-harvesting trough 1 is greater than the pipeline area of described rainwater water inlet pipe 2.By being set, rain gutter 1 can make the device of present embodiment better collect rainwater.
Particularly, in above-described embodiment of the present utility model, top, described two heavy chambers is provided with capping 6, and the chamber seal closures will described two when closing be sunk in this capping 6.
In addition, described capping can also be provided with observation port 7, can be observed the inner case (for example water level) in the two heavy chambers 9.
In sum, the utlity model has following advantage:
The utlity model has and necessarily store volume, can effectively remove early-stage rainwater, in addition, filtration, the precipitation that can also continue follow-up rainwater.Whole apparatus structure is simple, popularization degree height.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
