The lower surface of conical shell is provided with lower cylinder；The upper cylinder is located at the upside of the leakage hole, and the lower cylinder is located at
Multiple through-holes are offered on the wall surface of the downside of the leakage hole, upper cylinder and lower cylinder；Is provided in the lower cylinder
One floater shot, the upper cylinder top are provided with the second floater shot, and the diameter of second floater shot is more than the diameter of upper cylinder,
It is connected with connecting rod between first floater shot and the second floater shot；It is provided with and is opened in well seat above the third platform
Annular groove on wall, snap ring is arranged in the annular groove, and the snap ring shape is the ring-type with fracture.
Further, the material of first floater shot and the second floater shot is plastics, and is hollow.
Further, the lower face of the leakage hole is the arc to match with first floater shot.
Further, the diameter of first floater shot is equal to the diameter of the lower cylinder.
Compared with prior art, the advantageous effects of the utility model are as follows：
The utility model when water level is excessively high in sewer, along the upward levitating in the inside of lower cylinder block by the first floater shot
Scupper, and since the axial limiting of lower cylinder acts on, the double swerve that the first floater shot will not be rushed by the water in sewer,
Influence sealing effect；And after the first floater shot blocks leakage hole, the rainwater that top flows down retains in conical shell, by
Two floater shot levitatings, the second floater shot pull the first floater shot by connecting rod, and leakage hole is more deadly stifled, improve reverse-filling effect
Fruit.

Specific implementation mode
As shown in Figure 1, a kind of double balls interlock the one of which specific embodiment of reverse-filling well lid, including well seat 1 and well lid
2, the well seat 1 is fixed in the upper opening of sewer, the inner peripheral surface of well seat 1 form successively from top to bottom the first platform 101,
Second platform 102 and third platform 103.When installation, the well lid 2 is fastened on first platform 101, is opened up on well lid 2
There are multiple blastholes 201, rainwater etc. to be flowed into sewer from blasthole.It is fixed with filter screen 3 on second platform 102, from
The rainwater that blasthole flows into once through filter screen filtration prevents sundries etc. from entering sewer, causes sewer blockage.Described
Conical shell 4 is fixed on three platforms 103, the lower end of the conical shell 4 offers leakage hole 401, the upper surface molding of conical shell 4
There are upper cylinder 5, the lower surface of conical shell 4 to form lower cylinder 6, the upper cylinder 5 is located at the upside of the leakage hole 401,
The lower cylinder 6 is located at the downside of the leakage hole 401, and multiple through-holes are offered on the wall surface of upper cylinder 5 and lower cylinder 6
7, into the rainwater of conical shell, enters leakage hole from the through-hole of upper cylinder, flow downwardly into sewer.It is placed in the lower cylinder 6
There are the first floater shot 8,5 top of the upper cylinder to be placed with the second floater shot 9, the diameter of second floater shot 9 is more than upper circle
The diameter of cylinder 5, the diameter of first floater shot 8 are equal to the diameter of the lower cylinder 6, and first floater shot 8 and second floats
Connecting rod 10 is connected between floating ball 9.First floater shot can move up and down in lower cylinder, when water level mistake in sewer
Gao Shi, the first floater shot block scupper, and since the axial limiting of lower cylinder is made along the upward levitating in the inside of lower cylinder
With the double swerve that the first floater shot will not be rushed by the water in sewer influences sealing effect.The lower end of the leakage hole 401
Face is the arc to match with first floater shot 8, and sealing leakage hole is tighter.And in the first floater shot by leakage hole
After closure, the rainwater that top flows down retains in conical shell, and by the second floater shot levitating, the second floater shot is pulled by connecting rod
First floater shot, leakage hole is more deadly stifled.The material of first floater shot, 8 and second floater shot 9 is plastics, and is
It is hollow, floating force bigger.
As shown in Figure 1, 2,103 top of the third platform is provided with the annular groove 104 being opened on 1 inner wall of well seat,
Snap ring 11 is arranged in the annular groove 104,11 shape of the snap ring is the ring-type with fracture 1101.By the fracture of snap ring
Place's compression, makes the diameter of snap ring reduce, is put into groove, and after release, snap ring restores to the original state, and snap ring is stuck in annular groove, and
Conical shell is blocked, is prevented after water level is excessively high in sewer, by conical shell levitating.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are new to this practicality
