Description
Technical field
This utility model belongs to Road traffic devices technical field, is specifically related to a kind of convertible Safety manhole cover of stacking.
Background technology
The change of weather in recent years, many is born and is attacked by short time heavy rain, forms urban waterlogging.When city occurs
During waterlogging, for accelerating the discharge of rainwater, usually open inspection well cover in road.Open inspection well cover and be really conducive to the discharge of rainwater.
But rainwater muddy on road surface covers catch pit port, makes pedestrian easily determine error, falls into inspection shaft, simultaneously strong current strength,
Also make that the pedestrian falling into inspection shaft is the most unable to get away.Cause great life security incident, the most distressed！Media are reported in recent years
A lot of.Add a safety net at inspection shaft hole although also having, but often have after sewer services is constructed and forget the phenomenon that do not resets, also
There is safety net to lose phenomenon, cause when urban waterlogging, after opening inspection well cover, the unprotect measure of inspection shaft hole, causes safe thing
Therefore.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, it is an object of the invention to provide a kind of convertible peace of stacking
Full inspection well cover, has the features such as safe, antitheft, easy to use.
Technical scheme: in order to realize foregoing invention purpose, the technical solution used in the present invention is:
A kind of convertible Safety manhole cover of stacking, including inspection shaft frame, inspection well cover, Water Leakage cover and bearing pin；Described inspection shaft frame
In pier base, inspection shaft frame sets inspection well cover and Water Leakage cover by bearing pin；Wherein inspection well cover is stacked in above Water Leakage cover.
Respectively setting a pin-and-hole on the corresponding both sides of described inspection shaft frame, described inspection well cover and Water Leakage cover are respectively by right
Two pin-and-holes answered connect inspection shaft frame.
Being provided with two projections on described inspection well cover respective side edge, a projection is provided with pin-and-hole wherein.
Described inspection well cover is provided with leaking hole.
Described Water Leakage cover is the Water Leakage cover with security barrier structure.
Pin-and-hole it is provided with protruding at the edge of described Water Leakage cover.
Beneficial effect: compared with prior art, the convertible Safety manhole cover of stacking of the present utility model, simple in construction, if
Count ingenious, there is the features such as safe, antitheft, easy to use, there is good practicality, good economic benefit and society can be produced
Can effect.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, this utility model is described further.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the convertible Safety manhole cover of stacking, main structural components include inspection shaft frame 1,
Inspection well cover 2, Water Leakage cover 3 and bearing pin 4；Inspection shaft frame 1, in pier base 10, respectively sets a pin-and-hole 9 on the corresponding both sides of inspection shaft frame 1,
Being provided with two projections 6 on inspection well cover 2 respective side edge, a projection 6 is provided with pin-and-hole wherein, on the limit of Water Leakage cover 3
Edge is provided with pin-and-hole projection 7, inspection well cover 2 and Water Leakage cover 3 and is actively installed on inspection shaft frame 1 by bearing pin 4；Wherein inspection well cover 2 is stacked in leakage
Above water cover 3.Inspection well cover 2 is provided with leaking hole 5.Water Leakage cover 3 is the Water Leakage cover with security barrier structure 8.
Inspection well cover 2, Water Leakage cover 3 are connected with inspection shaft frame 1 by bearing pin 4, make inspection well cover 2, Water Leakage cover 3 can pass through bearing pin 4
Rotation realizes opening and closing.Bearing pin 4 can weld with inspection shaft frame, makes inspection well cover, Water Leakage cover will not off normal or lose, has anti-theft feature.
Inspection well cover is provided with leaking hole 5, can use as hook block hole, facilitate opening and closing.
In normal state, inspection well cover 2, Water Leakage cover 3, in layered laminate, cover in inspection shaft frame 1, i.e. cover inspection shaft hole,
Ensure normal pass.When there is urban waterlogging, when needing to promote draining, opening inspection well cover 2, making Water Leakage cover 3 still in covering simultaneously
Shape.Current flow rapidly into sewer by Water Leakage cover 3, and the security fence of Water Leakage cover 3 plays the effect of protection pedestrian simultaneously.Open
Perpendicular inspection well cover 2 plays good warning function.When needs enter sewer services construction, can be by inspection well cover 2, Water Leakage cover 3
Fully open, as it is shown in figure 5, make personnel to pass in and out.
