Description
Technical field
The utility model relates to rainwater stopped flow technique field, in particular to a kind of arc overflow weir Vatch basin.
Background technique
In China's municipal sewerage engineering, Vatch basin is used in confluence of rainwater and sewage system, in order to separate rain sewage.
Because there was only sewage in pipe when dry season, sewage can stop, be flowed in sewage pipe by Vatch basin, by part rainwater and sewage when rainy season
It stops and flows into sewage pipe, remaining stormwater overflow is continued downstream popular by weir in well.
For sewerage system, it is directly discharged into natural water more than the shut off initial rainwater of ability of main sewer, by
A large amount of floating materials and suspended matter are carried in initial rainwater, the initial rainwater without any processing is in line to enter natural water
When, by natural water quality of water environment and ecological environment cause serious pollution.
Currently, generalling use Vatch basin in the prior art intercepts floating material and suspended matter, it is still, most of existing to shut off
For well in long-time continuous operation, the inner wall of Vatch basin and the junction of overflow weir can accumulate sundries, result in blockage.
Utility model content
The purpose of the utility model is to provide a kind of arc overflow weir Vatch basins, can reduce the inner wall and overflow weir of Vatch basin
Junction accumulate sundries, avoid resulting in blockage in Vatch basin.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of arc overflow weir Vatch basin, including shut off well body and be oppositely arranged on the water inlet to shut off in well body with go out
The mouth of a river, the inner wall of the well body of shutting off are equipped with arc overflow weir, and the arc overflow weir is blocked in water inlet and water outlet
Connection side is upward, the inner wall arc transition of the two sides of the arc overflow weir and well body of shutting off, and the well body of shutting off is close to water inlet
The side wall of mouth is equipped with sewage draining exit.
By using above-mentioned technical proposal, municipal sewage, rainwater etc. flow into Vatch basin body via water inlet, arc overflow
Weir intercepts water inlet, and then is discharged via sewage draining exit, due to the inner wall arc transition of arc overflow weir and well body of shutting off, subtracts
Lack dirt in water body to remain in arc overflow weir and the junction for well body of shutting off, to avoid causing to block up in Vatch basin body
Plug.
The utility model is further arranged to: one end of the arc overflow weir extend in Vatch basin body be located at sewage draining exit with
On side wall between water outlet, the other end of the arc overflow weir extends in Vatch basin body between water inlet and sewage draining exit
Side wall on.
By using above-mentioned technical proposal, the one end for limiting arc overflow weir extends between sewage draining exit and water outlet, is another
One end extends between water inlet and sewage draining exit, shows arc overflow weir towards in water inlet side and Vatch basin body between wall
Interception area is formed, is forming overflow area between wall towards in water outlet side and Vatch basin body, to guarantee that arc overflow weir is sent out
Wave the preferable effect of shutting off.
The utility model is further arranged to: the well body of shutting off is equipped with shock resistance on the side wall of opposite water inlet and mends
Fourth, the shock resistance patch include the curved wall for being embedded on arc overflow weir and matching with the bending degree of arc overflow weir
And it is threaded through the stiffener in curved wall.
By using above-mentioned technical proposal, due to shut off well body with respect on the side wall of water inlet frequently by masses hit,
Shock resistance patch is added, wherein the stiffener contained, has excellent structural strength, helps to improve the anti-of arc overflow weir
Water slug performance.
The utility model is further arranged to: circular sliding slopes are equipped between the arc overflow weir and the inner wall for well body of shutting off
Wall forms acute angle between wall in the tangent line and Vatch basin body of the circular sliding slopes wall.
By using above-mentioned technical proposal, ensure that arc overflow weir between well body of shutting off is arc transition, and is refined
The degree of arc transition, compared with the prior art in for overflow weir is vertically set on the inner wall for well body of shutting off, subtract significantly
Residual of the dirt in arc overflow weir and Vatch basin body between wall in water body is lacked, guarantee does not shut off well body after prolonged use not
It can block.
The utility model is further arranged to: the height of the arc overflow weir is higher than water inlet, water outlet and sewage draining exit
Height, but lower than the tip height of well body of shutting off.
By using above-mentioned technical proposal, the height of overflow weir is limited, guarantees that overflow weir goes on smoothly interception, overflow is made
With.
The utility model is further arranged to: the bottom of the well body of shutting off, which is equipped with, is oriented to slope, in the guiding slope
Lower side close to sewage outfalls setting, and guiding the lower side in slope bottom of slope on be equipped with clean-up port.
By using above-mentioned technical proposal, be oriented to slope and play guide functions, intercepted municipal sewage, rainwater etc. along
It is oriented to the guiding on slope, is flowed to lower side, so that blowdown process is more quick；In addition, when lower side on guiding slope
When remaining excessive dirt, high pressure water is injected to clean-up port, dirt is backwashed, to improve the comprehensive of the well body of shutting off
Energy.
The utility model is further arranged to: the top of the arc overflow weir is equipped with mounting groove, sets in the mounting groove
There is interception grid.
By using above-mentioned technical proposal, it is mingled with the rubbish such as polybag in water body sometimes, setting intercepts grid can be to this
Class rubbish is intercepted, so that rubbish flows out from sewage draining exit, prevents rubbish from flowing into water outlet together with spilling water.
The utility model is further arranged to: the arc overflow weir is equipped with ladder platform towards the side of water outlet, described
The height of ladder platform is the 1/2 to 2/3 of arc overflow weir.
By using above-mentioned technical proposal, sewage density is larger, is located at below water body, and is mostly clear water above water body,
It when inflow is larger, has water source and passes through at the top of overflow weir, under the effect of gravity, fall and be discharged in arc overflow weir direction
Mouth side, setting ladder platform can be accepted and be buffered to spilling water；The height for limiting ladder platform, then can reduce the gravity of overflow water
Potential energy preferably plays buffer function.
In conclusion the utility model has the following beneficial effects:
1, it by the way that arc transition will be set as between wall in arc overflow weir and Vatch basin body, significantly reduces dirty in water body
Object helps to use the Vatch basin for a long time in the residual of arc overflow weir and well body junction of shutting off；
2, shock resistance pudding is added on arc overflow weir, helps to improve the service life of the arc overflow weir；
3, well body of shutting off bottom setting guiding slope, municipal sewage, rainwater can carry out water conservancy diversion along guiding slope, facilitate
Sewage is quickly discharged from sewage draining exit, when accumulation has a large amount of dirt, is backwashed to clean-up port injection high pressure water, with quick
Clear up the dirt in Vatch basin.
