Description
Technical field
The utility model is related to a kind of mine sensor cables, belong to field of cable technology.
Background technology
With the development of economy, electric power resource demand increasingly increases, and coal dosage is also increasing.Coal resources are opened
It adopts and is continued to increase with excavation difficulty, and in the adverse circumstances of the pressure changes such as deep-well, mine, sensor-based system equipment electricity consumption
Line cable lower and silicon pressure sensor, pressure difference transmitter etc. are connected, cable upper end and ground survey control system computer
Connection, cable easy fracture can not accurately detect liquid level, pressure change, timely feedback and detect warning device, Ke Nengzao to terminal
Into serious accident or even threaten the life securities of underground operators.Operating condition for occasions such as oil well, mines and
Severe working environment and environment, it is desirable that cable is with monitoring transmitter liquid level, pressure information is stable, tensile strength is big, anti-
Electromagnetic interference performance is superior outer, also to have the comprehensive performances such as high-low temperature resistant, warping strength, low smoke and zero halogen Environmental Safety.
Utility model content
This product realize purpose in order to it is timely, accurately by the variation of deep underground liquid level and pressure pass to terminal detection
Warning device provides a kind of with the comprehensive halogen-free environmental electromagnetism interference mine biography such as Environmental Safety, tensile strength height
Sensor cable.
The technical solution adopted in the utility model is thus：The utility model includes cable core, and combined screen is set successively outside cable core
Cover layer and oversheath, the cable core by gas-guide tube and be arranged on the insulated wire cores of gas-guide tube surrounding, reinforcing rib is twisted into；
The air guide tubular elastic is provided with the elastic supporting bar for supporting the gas-guide tube, the elasticity in the gas-guide tube
Supporting rod passes through the gas-guide tube center of circle.
The gas-guide tube axial direction is provided with several elastic supporting bars, and adjacent spring supporting rod offset angular is set
It puts.
The reinforcing rib is symmetrically distributed on the gas-guide tube surrounding.
Reinforcer is filled on the air guide tube wall.
The utility model has the advantages that：The utility model air guide tubular elastic is set, and improves the soft of the utility model cable
Property, make the utility model cable use more flexible；Furthermore the utility model sets elastic supporting bar, elasticity branch in gas-guide tube
Strut then gives gas-guide tube to provide certain support, when gas-guide tube because various factors deforms after due to the presence of elastic supporting bar
Gas-guide tube can be resetted, so as to ensure the cable performance of the utility model.
Furthermore the adjacent spring supporting rod offset angular setting of the utility model, can improve the anti-of gas-guide tube on the whole in this way
Press performance.
The utility model, filled with reinforcer, further improves the compressive property of gas-guide tube on air guide tube wall.

Specific embodiment
The utility model includes cable core, sets composite shielding layer and oversheath 6 successively outside cable core, the cable core is by gas-guide tube 1
Be arranged on the insulated wire cores 2 of 1 surrounding of gas-guide tube, reinforcing rib 3 is twisted；
The gas-guide tube 1 is elastic, and the elastic supporting bar 7 for supporting the gas-guide tube 1 is provided in the gas-guide tube 1, described
Elastic supporting bar 7 is by 1 center of circle of gas-guide tube.
1 axial direction of gas-guide tube is provided with several elastic supporting bars 7, adjacent spring 7 offset angular of supporting rod
Setting.
The reinforcing rib 3 is symmetrically distributed on 1 surrounding of gas-guide tube.
Reinforcer 8 is filled on 1 tube wall of gas-guide tube.
For the utility model centered on a gas-guide tube 1, it is right that surrounding is symmetrical arranged three insulated wire cores, 2, three reinforcing ribs 3
Claim twisted synthesizing cable, internal shield 4,5 composite shielding layer of external shielding layer are set after stranding, outermost layer extrudes oversheath 6.
2 conductor of the utility model insulated wire cores is using multiply is anti-oxidant, the corrosion-resistant tin plating soft round regular formula of copper stranded conductor is twisted；
Insulating layer uses Low temperature-resistancorrosion-resistant corrosion-resistant novel flexible polyolefin high-molecular compound material；
The gas-guide tube 1 of the utility model is located at the center of cable core, is used for transmission detection liquid level, pressure change displacement information,
High-strength polyolefin material can be used to extrude；First gas-guide tube one end will be sealed in cable core stranding process, one section inflation, make its
Stranding under swelling state, ensure that cable core rounding in production process.
Reinforcing rib 3 use multiply flexible high-intensity carbon steel wire concentric stranding, then extruded insulation layer form, outer diameter and
Ensure that its insulated wire cores outer diameter is consistent, so that rounding is uniform during cable molding.
Internal shield 4 uses heat-insulated, moisture-proof aluminium-plastic tape, and aluminium surface is faced out and is wrapped on cable conductor,
Form one layer of anti-interference shielded layer.
External shielding layer 5 uses anti-oxidant, corrosion resistant tin-plating round copper wire woven shield, and cable is made to form double shield knot
Structure strengthens the interference free performance of cable, enhances the tensile strength of cable.
Oversheath 6 is using the nontoxic novel elastic Radiation Crosslinked Polyethylene of high temperature resistant, low smoke and zero halogen, using squash type technique
It squeezes out, close structure rounding is easy to cable laying installation wiring.
