Background technique
With various urban infrastructure gradual perfections, higher want is proposed to construction and the maintenance of underground power pipeline
It asks, but urban electric power pipeline is when encountering the extreme weathers such as thunderstorm, typhoon, since pipeline communicates between each well,
After long-term rainwater, sewage, mud etc. can penetrate into pipeline or mouse worm scurry into breeding, death rot to will cause pipeline it is stifled
Plug, and mouse gnaws cable outer wall will cause broken accident outside cable.The heavy workload for maintenance of drawing water is communicated as well as pipeline
It is big to increase, especially because certain section of cable break down because can not be segmented draw water due to cannot debug that cause can not be estimated in time
Loss, greatly reduce the power supply reliability of urban power distribution network.Investigation display, similar fault condition many cities all very
Generally, relevant departments pay little attention to for a long time, and in urban construction, consideration is not complete, are not sealed effectively to cable pipeline
It is stifled.Solution is to carry out waterproof sealing to cable channel, not only realizes cable pipe trench waterproof, moreover it is possible to be effectively prevented toy
Invasion.
It is mainly at present that the solidification for using fire-proof mud, cement, foaming agent, sealing bolt etc. traditional seals to cable blocking technology
Technology.But traditional blocking technology, since between material and pipeline the effect of waterproof can be lost because expanding with heat and contract with cold and cracking, in addition only
Seal for pipe joints material will be destroyed by wanting cable to do the operations such as joining seam maintenance, need to reseal, also not to cable dilatation in the future
It is convenient.Pipeline has been fixed to block and has needed to restore that entire pipeline may can be destroyed simultaneously.
Utility model content
In order to solve the problems, such as to mention in above-mentioned background technique, it is stifled that the utility model provides a kind of power cable pipeline waterproof
Device.
To achieve the goals above, the utility model adopts the technical scheme that
The upper end outer wall of a kind of power cable pipeline waterproof block apparatus, including pipe main body, the pipe main body is communicated with
Two symmetrical first pipe mouths and second pipe opening are equipped with cable, the outer wall of the cable in the pipe main body
There are two annular inflatable pads for socket, and the annular outer wall of annular inflatable pad is equipped with one layer of annular thickening washer, the annular inflatable
The annular inner wall of pad is equipped with one layer of sealing ring, and the outer wall side of the annular inflatable pad is communicated with gas tube, and gas tube is outer
It is fixedly connected with fixed block at wall, the junction of the gas tube and annular inflatable pad is equipped with non-coring, and the end of non-coring
It is fixedly connected with end cap, the outer wall side of the end cap is fixedly connected there are two symmetrical piston block, the annular inflatable pad
Outer wall is equipped with accommodating groove corresponding with piston block, and is connected with spring between piston block and the bottom wall of accommodating groove.
Preferably, the outer wall of the annular thickening washer is bonded with the tube wall of pipe main body.
Preferably, the inner wall of the sealing ring is bonded with the outer wall of cable.
Preferably, the gas tube is socketed with sealing cover far from one end outer wall thread of annular inflatable pad.
Preferably, two gas tubes are L-type structure, and gas tube is respectively to first pipe mouth and second pipe opening
Extend.
Compared with prior art, the utility model has the beneficial effects that
1, in use, being directed at gas tube by air blower first, it will be socketed on the annular inflatable pad of cable outer wall in advance
It is inflated, due to certain air pressure, so that non-coring is detached from gas tube, but in the case where the elasticity of spring restrains, so that living
Chock is without departing from accommodating groove, and air pressure can open non-coring, to be inflated to annular inflatable pad, so that annular thickeies
The outer wall of washer is bonded with the tube wall of pipe main body, and the inner wall of sealing ring is bonded with the outer wall of cable, finally realizes water-proof plug
Effect；
2 and after inflation, air pressure in annular inflatable pad can pressed end lid, so that non-coring be made to block inflation
The opening of pipe, and then realize and block, while tightening sealing cover, gas leak phenomenon is avoided, and finally can be realized adjacent at two
Rainwater, sewage discharge between first pipe mouth and second pipe opening.
To sum up, the utility model structure is simple, easy to operate, improves the effect of seal for pipe joints, and can be convenient for will be in pipeline
The water of generation is extracted out, and it is suitable for being widely popularized that easy to maintenance, the device is easy to use ingenious.
