Abstract
The utility model relates to a device, belonging to the cable field, which is characterized in that: a lead is of an embedding and enwrapping structure of three or more than three layers; a flexible material layer and a surface protective layer are arranged outside an insulation layer of a metal core wire; the flexible material layer is arranged between the insulation layer and the surface protecting layer. The utility model is cooperated with a sensor or a lens, and can be applied to long-distance detection and inspection of buried horizontal pipes and small-caliber canals; the utility model has a good result for leakage inspections of pipeline-laying inflation cables of telecom departments, avoids long-distance digging of pipelines, and saves a lot of maintenance cost.
Description
The utility model belongs to field of cables, relate to a kind of be applicable to underground long-distance pipe and small-bore irrigation canals and ditches are surveyed use, be used for transducer and detector or camera lens and video camera couples together and transmission of electric signals, the vertically flexible and flexible lead of lateral stiffness.
In the prior art, when detecting, need probe or camera lens and connect to send into after lead is fixed, supported with bar or rod for the situation in buried pipe that can't excavate or the small-bore irrigation canals and ditches.If on-the-spot narrow and small, pipe under test or irrigation canals and ditches occur crooked or their distances are long then can't detect.
The purpose of this utility model, provide and a kind ofly need not add any support fixation, can make lead (together with the transducer or the camera lens that connect) enter that hettocyrtosis, long-distance pipe or small-bore irrigation canals and ditches detect, the vertically flexible and flexible lead of lateral stiffness.
In order to achieve the above object; the utility model provides a kind of flexible lead; comprise insulating barrier and be insulated the metal core wire that layer wraps up; it is characterized in that: this lead is to inlay the packaging type structure more than three layers or three layers; insulating barrier periphery in metal core wire is provided with flexible material layers and sealer, and flexible material layers is between insulating barrier and sealer.
Described flexible material layers is by glass fibre and epoxy resin is compound constitutes.Described metal core wire can be split conductor or only heart yearn.Also be provided with screen between described flexible material layers and the insulating barrier.Described screen can adopt metal forming or woven wire or other shielding form.The horizontal section configuration of described flexible lead can be circle, polygon, square or other shapes.Described sealer is the polyethylene rigid plastics.
Compared with prior art, the utlity model has following characteristics:
1. the utility model tool certain degree of hardness, vertically be pliability and laterally be stronger rigidity, thereby carry out buried pipe or irrigation canals and ditches when detecting, and need not add any bar or excellent support fixation, can make and self directly enter destination to be measured together with the transducer or the camera lens that connect.
2. flexible material layers of the present utility model makes lead integral body have good pliability, can be not less than the coiling of 80 cm as diameter, after testing coiling several years of storage like this, stretch and use, it is flexible not to subtract, thereby saved greatly and deposited and usage space, even tested buried pipe or irrigation canals and ditches are because of being influenced by external force to bend or when subsiding, the utility model is also reliable self flexiblely to be entered smoothly and passes through.
3. the duroplasts of surface protection series of strata thermoplastic manufactured of the present utility model, is difficult for plastic deformation at wear-resisting, waterproof, non-frangibility.
Below in conjunction with accompanying drawing the utility model is further elaborated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the transverse sectional view of Fig. 1.
Among Fig. 1 and Fig. 2, structure of the present utility model comprises metal core wire 1, insulating barrier 2, flexible material layers 3, screen 4 and sealer 5, and flexible material layers 3 is between insulating barrier 2 and sealer 5.Metal core wire 1 can be only heart yearn or split conductor; insulating barrier 2 adopts rubber or other insulating material; screen 3 adopts metal forming or woven wire; flexible material layers 4 is by highly elastic fiber material (for example glass fibre) and the compound formation of epoxy resin, and sealer 5 adopts polyethylene rigid plastics thermoplastic manufactured.
The utility model can be made into the random length that needs, and finished product has certain degree of hardness, and pliability is good, smooth surface.Finished product is deposited after can being not less than the coiling of 80cm as diameter, stretches after testing coiling like this to deposit 5 years and uses, and its pliability does not subtract.An end of the present utility model can be connected the corresponding interface of other end joint detection instrument or video camera with transducer or camera lens during actual the use.Transport the flexible lead of one-tenth dish to the detection job site, flexible lead (together with the transducer or the camera lens that connect) is sent into the buried pipe or the irrigation canals and ditches that need detection, begin to detect operation from detecting the hole; After operation finishes, regain flexible lead (together with the transducer or the camera lens that connect), still can coil and deposit.
The utility model cooperates with transducer or camera lens, applicable to long range sensing, inspection to buried horizontal pipe, small-bore irrigation canals and ditches, especially the gas-filled type cable that the telecommunication department duct type is laid carries out leak test fabulous effect, avoid the long distance excavation of pipeline, can save a large amount of maintenance costs.
