Description
Technical field
The utility model relates to the dirty cut-off equipment of a kind of rain, relates in particular to the dirty cut-off equipment of the automatic rain of a kind of waterpower.
Background technology
For a long time, old town, most of city has only the sewerage system of a cover pipe network, the dirty mixed flow of rain is loose arranges, promptly adopt combined system directly rainwater and sanitary sewage to be entered near the city the waters nearby, cause the water body severe contamination, water quality sharply worsens, going to wreck property of water ecological setting destruction.Therefore transforming the interflow, to be made as segregation system imperative.But because that the old town will be transformed into the cost that two cover pipe networks shunt discharging to rainwater and sewage is too high,,, still continue to use a cover pipe network, the rainwater sewage of mixed flow is handled in order to save cost so be transformed in the process of segregation system at combined system.The shutoff type combined drainage system is adopted in the city mostly at present, in light rain season in dry season, Wastewater Treatment Plant normally moves processing, but to flood season, during particularly big amount of rainfall,, be to save cost because the load of treatment plant is limited, directly discharge when amount of rainfall acquires a certain degree, Wastewater Treatment Plant is out of service.
But, all be in the past by closing the operation of damming of Wastewater Treatment Plant's valve manually.The complicated adverse circumstances because sewage dams, there are shortcomings such as maintenance cost height, poor reliability in this operation.
Summary of the invention
The dirty cut-off equipment of automatic rain of the present utility model is intended to overcome above-mentioned shortcoming, by hydraulic action combined sewage is realized automatic-diversion closure.Dry season, sewage all dammed during flowing water; The early-stage rainwater amount is less, when pollution concentration is higher, sewage and rainwater all dam and enter the sewerage treatment pipeline that dams.Flood season heavy rain, pollute relatively hour, the mixed flow sewage of a large amount of rainwater and relative trace directly enters in the waters nearby in city under the closing automatically of cut-off equipment.
The utility model is that the technical scheme that is adopted that achieves the above object is: the dirty cut-off equipment of rain automatically, the casing 1 that comprises cuboid, be arranged on the center of casing 1 and intercepting sewer 2 that front and back connect casing 1 and the valve plate 21 that is arranged on intercepting sewer 2 centers, it is characterized in that: the both sides of the front panel 11 of described casing 1 are provided with the inlet opening 15 of leading to cabinets cavity 3, two buoyancy aids 31 are housed in this cabinets cavity 3, described buoyancy aid 31 runs through this intercepting sewer 2 by level axle 4 and described valve plate 21 are rigidly connected to be one, thereby makes axle 4 rotate and then open or close valve plate 21 by moving up and down of buoyancy aid 31.
Preferably, be embedded with grid 25 at water inlet 23 places of described intercepting sewer 2.
Preferably, grid 25 is a stainless steel material.
Preferably, described axle 4 is welded on the described valve plate 21 prejudicially.
Further preferably, described inlet opening 15 is arranged on horizontal plane 1/3 to 1/2 place, place, 11 liang of lateral extent intercepting sewer 2 bases of front panel.
In addition preferably, casing 1 and/or valve plate 21 adopt oil resistant, acidproof, alkaline-resisting anti-corrosion material to make.
Also preferably, described buoyancy aid 31 is a cylindrical shape.
Further preferably, described buoyancy aid 31 is a spheroid.
By above-mentioned scheme, the dirty cut-off equipment of automatic rain of the present utility model has realized that with less relatively pipeline shunting improvement project amount automatic rain dirt dams, easy construction, instant effect, and also maintenance cost is low, good reliability.

Fig. 1 is the elevation of the dirty cut-off equipment of automatic rain of the present utility model;
Elevation when Fig. 2 removes front panel for the dirty cut-off equipment of automatic rain of the present utility model.
Wherein: 4 11 front panels of 1 casing 2 intercepting sewers, 3 cabinets cavities, 15 inlet openings, 21 valve plates, 23 water inlets, 25 grids, 31 buoyancy aids
The specific embodiment
As shown in Figure 1, 2, the dirty cut-off equipment of automatic rain of the present utility model is the body structure of cuboid, select oil resistant, acidproof, alkaline-resisting anti-corrosion material manufacturing for use, the center, three-dimensional chamber of casing 1 is the intercepting sewer 2 that front and back connect casing 1, intercepting sewer 2 caliber centers are provided with the valve plate 21 that is used for throttling, caliber water inlet 23 places are embedded with stainless grid 25, to play the anti-stifled effect of barrier foreign material.The both sides of the front panel 11 of casing 1 are provided with the inlet opening 15 of leading to cabinets cavity 3, and described inlet opening 15 is arranged on apart from horizontal plane 1/3 to 1/2 place, place, intercepting sewer 2 base.Two buoyancy aids 31 are housed in this cabinets cavity 3, described buoyancy aid 31 runs through intercepting sewer 2 by level axle 4 be one in that this described valve plate 21 on 4 is rigidly connected.Preferably, described axle 4 is welded on the described valve plate 21 prejudicially, and when valve plate 21 was closed, this was positioned at the downside of valve plate 21 horizontal center lines, thereby made that the valve plate upside is subjected to bigger impact force in the water level uphill process.Simultaneously, for not having to make valve plate 21 keep opening fully under the situation of buoyancy, need adjust the angle of inclination between buoyancy aid 31 and the valve plate 21.Sagging naturally and when leaning on the bottom surface of casing 1 towards front panel 11 directions when buoyancy aid 31 bottoms, valve plate is just in time opened fully.In addition, buoyancy aid 31 can be cylindrical shape or spheroid, to improve buoyancy.
The course of work of the dirty cut-off equipment of automatic rain of the present utility model will be described below.During less than caliber 1/3, because the effect of the gravity of valve body own, the valve plate 21 of cut-off equipment is in normally open at water level, all dams into Wastewater Treatment Plant's pipeline during a small amount of rainwater at sanitary sewage and initial stage.When water level surpasses caliber 1/3, increase along with amount of rainfall, water enters into cabinets cavity 3 via the inlet opening on the front panel 11 15, buoyancy aid 31 in the cabinets cavity 3 rises under buoyancy, drive 4 pairs of valve plates of axle 21 and produce the active force that trend is closed, because of the rotation disalignment of valve plate 21, the valve plate upside is subjected to the longitudinal impact force of water simultaneously, under several effects of making a concerted effort, the opening angle of valve plate increases and diminishes gradually with water level.When water level increase to greater than the caliber water level 3/4 the time, valve plate 21 is entirely closed.When drawdown to less than caliber water level 3/4 time owing to make a concerted effort to reduce, along with the decline gradually of water level, valve plate 21 is opened gradually, until opening fully.
By the dirty cut-off equipment of automatic rain of the present utility model, alleviated the load of urban sewerage and drainage and sewage disposal system, realized the automatic opening and closing of the dirty cut-off equipment of automatic rain under unmanned situation.Rainwater, sewage have been played in city municipal drainage pipe network transformation and construction controlled the effect of shunting automatically, thereby alleviated the cost in the sewerage treatment greatly.
To sum up, the utility model encyclopaedizes by the above embodiments.In not breaking away from spirit and scope of the present utility model, the utility model can be made many distortion, and they all fall among the utility model scope required for protection.
