Abstract
The utility model discloses the cesspool covers that a kind of rainwater-proof penetrates into.One self-seal device is installed in the lower section in existing cesspool cover back center hole；Self-seal device includes metal sealing seat, sealing strip and fixation expansion bolt；Metal sealing seat includes barrel and flange plate, sealing strip is the rubber material of water-swellable dehydration shrinkage, it is placed in the shape of a spiral in the barrel of metal sealing seat, bolt hole is provided on flange plate, sealing device is anchored on to the lower section in well lid back center hole by expansion bolt；Formed when sealing strip dehydration shrinkage with the comparable shrinkage hole of center hole size of well lid, when sealing strip water-swellable, shrinkage hole is in closed form.Cesspool cover provided by the utility model, ventilates when non-irrigated, self sealss when rain, does not influence well lid keying, can greatly reduce rainwater infiltration, reduce sewage plant operating cost, have the foreground promoted and applied.
Description
Technical field
The utility model is related to a kind of cesspool covers can effectively prevent infiltration rainwater, especially suitable for rain sewage diversion
Municipal sewage collection system system can effectively reduce rainwater and penetrate into sewage network, improve sewage treating efficiency.
Background technology
Rain sewage diversion is to improve the important leverage of city river water environment, and the rainy city in national clear stipulaties south must be real
The run-off system of row rain sewage diversion.The requirement of various regions newly built city district strict implement rain sewage diversion, old town are also basically completed rain dirt
Shunting transformation.But the city of rain sewage diversion is had been carried out, the problem of rainy day sewage treatment plant inflow amount increases severely is commonly encountered,
Amplification reaches 30%~50%.A large amount of rainwater enter sewage network, on the one hand considerably increase processing cost, it is often more important that tie up
The processing space of urban sewage treatment system, the sewage of pipe of causing to have received enter river, pollute urban environment again.
The cesspool cover in city is generally provided with two apertures to balance the air pressure inside and outside well and be convenient for opening.Due to
Well lid enormous amount, this aperture penetrates into the main thoroughfare of sewage network at rainwater, currently, there are no this respects for the whole industry
Disposal Measures.
Invention content
The utility model penetrates into asking for sewage network for the existing a large amount of rainwater in rain sewage diversion city through bilge well cap bore
Topic provides a kind of cesspool cover that can effectively prevent and penetrate into rainwater.
Realize that the technical solution of the present utility model purpose is to provide a kind of cesspool cover that rainwater-proof penetrates into, well lid is opened
There is centre bore, one self-seal device is installed in the lower section in well lid back center hole；The self-seal device includes that metal is close
Seal seat, sealing strip and fixation expansion bolt；Metal sealing seat includes barrel and flange plate, and sealing strip is received for water-swellable dehydration
The rubber material of contracting is placed in the barrel of metal sealing seat, bolt hole is provided on flange plate in the shape of a spiral, will by expansion bolt
Sealing device is anchored below the centre bore at the well lid back side；It is formed when sealing strip dehydration shrinkage suitable with the center hole size of well lid
Shrinkage hole, when sealing strip water-swellable, shrinkage hole is in closed form.
Compared with prior art, the beneficial effects of the utility model are：
1. preventing bilge well cap bore from penetrating into the self-seal device of rainwater by setting, rainwater is blocked to penetrate into sewage network
Main channel, maintains original well lid aperture balance well inner and outer air pressure usually and the function convenient for unlatching, simple installation are at low cost
It is honest and clean.
2. ventilating when the cesspool cover drought provided, self sealss when rain do not influence well lid keying, can greatly reduce rainwater and ooze
Enter, reduce sewage plant operating cost, discharges the processing space of the urban sewage treatment system tied up by invasion rainwater, avoid
The sewage of pipe received enters river again, has the foreground promoted and applied.

Embodiment 1
Cesspool cover provided in this embodiment includes well lid and self-seal device, and well lid is provided with centre bore, with existing dirt
Well cover is similar, and self-seal device is fixed on the central hole of well lid reverse side.
Referring to attached drawing 1, it is the schematic diagram of self-seal device structure provided in this embodiment；It includes seal receptacle 1, sealing
Item 2.For the structural schematic diagram of seal receptacle referring to attached drawing 2, seal receptacle is metal product, is made of barrel 4 and flange plate 5, barrel
A diameter of D, bottom are provided with the hole consistent with well lid center bore dia d, bolt hole 3 are provided on flange plate, will by expansion bolt
Self-seal device is fastened on the reverse side of cesspool cover.
Referring to attached drawing 3, it is the schematic diagram of sealing strip in the deployed state.Sealing strip is done spiral, is placed on close
It seals in seat, sealing strip is made by the butyl material of water-swellable dehydration shrinkage, with more convenient expansion and is shunk.Referring to
Attached drawing 4, when dry, sealing strip is contraction state, and outer diameter is consistent with barrel diameter D, the size and well of the centre bore d that centre is formed
Lid centre bore is suitable, ensures ventilation and convenient for opening.Referring to attached drawing 5, when the rainy day, sealing strip water-swellable, centre bore closes automatically
It closes, rainwater has been blocked to penetrate into sewage network.
