Description
Technical field
This utility model relates to municipal administration underground construction and builds auxiliary equipment technical field, particularly relates to a kind of Safety well cover.
Background technology
Well lid is the most common, is mainly used in covering the various pipes such as the cable channels such as underground electric telecommunications, urban operating mechanism subsoil drain and being arranged on ground opening.Existing manhole cover structure mainly includes cage and cover plate, cage is embedded in the underground at pipeline tapping, and cage upper end inwall is convexly equipped with a circle step for support cover plate, and cover plate activity is embedded in cage to close the opening of cage, when covering, the lower surface of cover plate coordinates with step upper surface.But, owing to cover plate is that removable cover is combined on cage, once meeting with Rainstorm Flood weather, cover plate is the most upwards lifting under the effect of hydraulic pressure in well, thus causes cover plate washed away, thus produces potential safety hazard.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of reasonable in design, simple in construction, cover plate can be according to the Safety well cover of borehole pressure automatic lifting.
For achieving the above object, this utility model is by the following technical solutions:
A kind of Safety well cover; it includes cover plate and cage; described cage upper end inwall is convexly equipped with a circle step, and cover plate activity is embedded in cage, and the lower surface of cover plate coordinates with step upper surface; more than one air spring it is fixed with on described step; the piston rod of air spring is connected with cover plate, is arranged with telescopic protection set outside the piston rod of air spring, and protection set upper side is tightly connected with cover plate lower surface; protection set lower end is tightly connected with step upper surface, is arranged with containment vessel outside the pressure cylinder of air spring.
As preferably, described step be provided with more than one for the T-shaped installation through hole installing air spring, described containment vessel is T-shaped, and containment vessel upper end is fixed in T-shaped installation through hole, and step lower surface is stretched out in containment vessel lower end.
As preferably, described step is provided with more than one and is completely fixed in installing blind for the installing blind installing air spring, described containment vessel.
Further, described protection set is by anti-corrosive rubber material molding.
Further, described containment vessel is by resistant material molding.
This utility model uses above technical scheme, by air spring, cover plate is connected with cage, it is possible not only to effectively prevent cover plate washed away or stolen by people, thus reduce loss, guarantee pedestrains safety, and cover plate can be increased at well internal water accumulation, when hydraulic pressure raises, hydraulic pressure is utilized to overcome the elastic force of air spring, the piston rod of air spring is automatically by cover plate jack-up, well internal water accumulation overflows from the opening part between cover plate and cage, when well internal water accumulation tails off, when hydraulic pressure declines, under cover plate self gravitation effect, the piston rod of air spring starts return, cover plate falls after rise and again covers on cage, therefore, under the effect of air spring, no matter cover plate is to rise or fall, cover plate all can be positioned at above well head, effectively prevent well head and gulp down people's phenomenon, substantially increase safety；Protection set and the design of containment vessel; can effectively protect piston rod and the pressure cylinder part of air spring, it is to avoid it directly has corrosivity, the gas of contaminative or liquid in the contact external world, causes air spring to damage; thus extending the service life of air spring, it is ensured that it normally works.This utility model is reasonable in design, simple in construction, and having cover plate can be according to the function of borehole pressure automatic lifting.

Detailed description of the invention
As shown in one of Fig. 1-4; this utility model includes cover plate 1 and cage 2; described cage 2 upper end inwall is convexly equipped with a circle step 21; cover plate 1 activity is embedded in cage 2; the lower surface of cover plate 1 coordinates with step 21 upper surface; more than one air spring 3 it is fixed with on described step 21; the piston rod 31 of air spring 3 is connected with cover plate 1; telescopic protection set 4 it is arranged with outside the piston rod 31 of air spring 3; protection set 4 upper ends are tightly connected with cover plate 1 lower surface; protection set 4 lower ends are tightly connected with step 21 upper surface, are arranged with containment vessel 5 outside the pressure cylinder 32 of air spring 3.
Described protection set 4 is by anti-corrosive rubber material molding.
Described containment vessel 5 is by resistant material molding.
Embodiment 1
As shown in Figure 1 or 2, described step 21 be provided with more than one for the T-shaped installation through hole installing air spring 3, described containment vessel 5 is T-shaped, and containment vessel 5 upper end is fixed in T-shaped installation through hole, and step 21 lower surface is stretched out in containment vessel 5 lower end.
Embodiment 2
As shown in Figure 3 or Figure 4, described step 21 is provided with more than one and is completely fixed in installing blind for the installing blind installing air spring 3, described containment vessel 5.
nullThis utility model uses above technical scheme，By air spring 3, cover plate 1 is connected with cage 2，It is possible not only to effectively prevent cover plate 1 washed away or stolen by people，Thus reduce loss，Guarantee pedestrains safety，And cover plate 1 can be increased at well internal water accumulation、When hydraulic pressure raises，Hydraulic pressure is utilized to overcome the elastic force of air spring 3，The piston rod 31 of air spring 3 is automatically by cover plate 1 jack-up，Well internal water accumulation overflows (figure shown in arrow) from the opening part between cover plate 1 and cage 2，When well internal water accumulation tails off、When hydraulic pressure declines，Under cover plate 1 self gravitation effect，The piston rod 31 of air spring 3 starts return，Cover plate 1 falls after rise and again covers on cage 2，Therefore，Under the effect of air spring 3，No matter cover plate 1 is to rise or fall，Cover plate 1 all can be positioned at above well head，Effectively prevent well head and gulp down people's phenomenon，Substantially increase safety；Protection set 4 and the design of containment vessel 5; can effectively protect piston rod 31 and pressure cylinder 32 part of air spring 3, it is to avoid it directly has corrosivity, the gas of contaminative or liquid in the contact external world, causes air spring 3 to damage; thus extending the service life of air spring 3, it is ensured that it normally works.
Above description should not have any restriction to protection domain of the present utility model.
