And the pedestrian threatened and the safety of vehicular traffic.
Utility model content
The utility model is for overcome the deficiencies in the prior art, there is provided a kind of small sewer of impulsive force for being subject to when pouring in down a chimney
Well lid.
To achieve these goals, the utility model uses following technical scheme：A kind of well cover for sewer, including upper cover body
With the lower cover being movably connected in upper cover body, the upper cover body is provided with the first drainage gallery, and the upper cover body, which is provided with, inserts
Part, the lower cover are provided with the second drainage gallery coordinated with plug-in unit, may be reversed in the upper cover body and be connected with the first capping,
It may be reversed on the lower cover and be connected with the second capping.When the current in sewer pipe pour in down a chimney, under be sealed on hydraulic pressure
Moved up under effect, now the plug-in unit in upper cover body can be inserted in the second flood discharge passage, and then the second capping is turned over downwards
Turning, current can be entered in the first flood discharge passage by the second flood discharge passage, and first is sealed in the presence of current and is flipped up,
Current can flow out to the surface of well lid, and then reduce the impulsive force that well lid is subject to, it is therefore prevented that work of the well lid in impulsive force
Rushed with lower, beneficial to the safety for ensureing pedestrian and vehicular traffic.
Further, the upper cover body is provided with the groove for accommodating the first capping, and the lower cover, which is provided with, accommodates second
The cavity of capping；Capping is in groove, it is therefore prevented that capping is compromised.
Further, the upper cover body is provided with an at least intake tunnel, and the intake tunnel side wall is downwardly extending
Connecting pole, the lower cover are provided with the exhalant canal passed through for connecting pole, and the connecting pole is provided with limiting section；Lower cover is lived
It is dynamic to be set on connecting pole, and the limiting section for preventing lower cover from coming off is additionally provided with connecting pole, so realize lower cover with
The flexible connection of upper cover body, lower cover can move up under hydraulic pressure active force along connecting pole.
Further, the lower cover is provided with ball float；When current pour in down a chimney, ball float adds the floating of lower cover
Power, moved up beneficial to lower cover.
Further, the plug-in unit is the flange that the first drainage gallery side wall is downwardly extending；Plug-in unit and upper cover body are
It is integrally formed, is easy to manufacture.
In summary, the utility model by setting flood discharge passage respectively on upper and lower cover body, when the water in sewer pipe
When pouring in down a chimney impact well lid, lower well lid moves up, and second is sealed in the presence of plug-in unit and downwardly turns over, and then current can lead to successively
The second flood discharge passage, the first flood discharge passage are crossed, the first capping is finally washed open and flows out to outside well lid, well when reducing flow backwardses
The impulsive force being subject to is covered, reduces the harm to pedestrian and vehicular traffic.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Embodiment
In order that those skilled in the art are better understood from the utility model, it is real below in conjunction with the utility model
The accompanying drawing in example is applied, clear, complete description is carried out to the technical scheme in the embodiment of the utility model.
As shown in Figure 1-2, a kind of well cover for sewer, including upper cover body 1 and the lower cover 2 that is movably connected in upper cover body 1,
The upper cover body 1 is provided with the first drainage gallery 11, and the upper cover body 1 is provided with plug-in unit 12, specifically, the plug-in unit 12 is the
The flange that the side wall of one drainage gallery 11 is downwardly extending, the lower cover 2, which is provided with second coordinated with plug-in unit 12 and sluiced, to be led to
Road 21, it may be reversed in the upper cover body 1 and be connected with the first capping 13, specifically, first capping 13 is a plastic plate and logical
Cross the upper surface that torque spring is connected to upper cover body, during normal state, plastic plate can be let out in the presence of torque spring to first
Big vast passage 11 is covered, and be may be reversed on the lower cover 2 and is connected with the second capping 22, likewise, first capping 22 is
One plastic plate and the upper surface that upper cover body is connected to by torque spring, during normal state, effect of the plastic plate in torque spring
Under the first flood discharge passage 21 can be covered,
The infringement being subject to is covered in order to reduce during use two pieces, is provided with the upper cover body 1 and accommodates the first capping
13 groove 14, the lower cover 2 is provided with the cavity 23 for accommodating the second capping 22, and during normal state, capping is at groove
It is interior, and then prevent pedestrian and vehicular traffic to damage the first capping 13
Further, the upper cover body 1 is provided with 8 intake tunnels 15, and the intake tunnel 15 is circumferentially spaced uniformly
It is distributed in the edge of upper cover body 1, the cylindric connecting pole 16 that the side wall of intake tunnel 15 is downwardly extending, the lower cover
2 are provided with the exhalant canal 24 passed through for connecting pole 16, and the connecting pole 16 is provided with limiting section 17, the specific limiting section
17 be the boss that the connecting pole 16 outwardly extends formation, and the lower cover 2 is movably set on connecting pole 16, and can
Moved up and down between boss and the lower surface of upper cover body 1.
Preferably, the lower cover 2 is provided with ball float 25, when current pour in down a chimney, ball float add lower cover by
