Background
In some areas where people are noisy, such as factory workshops and the like, some cables laid on the ground are often subjected to treading or cargo extrusion, so that better pressure resistance is required for the exposed cables, the protection performance of common cables is general, and after long-term use, the loss of the cables is increased due to continuous treading or extrusion, and the service life is greatly reduced.
In high temperature operation area, need the cable to have extremely strong thermal diffusivity, prevent that high temperature from arousing the condition that the cable can not normally work, in addition, cable among the prior art often with PVC protective layer direct contact, when consequently receiving the cutting, the damage cable core of first making the best of things leads to economic loss, the cable thermal diffusivity among the prior art is poor, resistance to compression protective properties is also relatively poor.
In addition, after the discarded cable is discarded, the internal cable core is usually more valuable, if the discarded cable core is discarded completely, a lot of cost is wasted, but the cable core is tightly wrapped by the PVC protective layer, the cable core is not easy to draw out, the PC protective layer needs to be cut, and then the internal cable core is taken out, so that the operation procedures are increased, and the working efficiency is reduced.
Chinese patent No. CN108538483B discloses a high-efficiency heat-dissipating composite cable, which includes a cable outer layer, and set up the cable core in the cable tegillum, be provided with an installation cavity in the middle of the cable tegillum, be provided with the plastic hose more than in the installation cavity side by side, the plastic hose sets up the centre department at the installation cavity side by side, the both ends of plastic hose insert respectively in the through-hole that the cable tegillum both sides were seted up, it is fixed to bond through glue between the outer wall of the inserting end of plastic hose and the through-hole inner wall, the both ends opening of plastic hose, the bottom of plastic hose all is provided with two pipes that absorb water, it is provided with a water absorption channel to absorb water intraductally, be provided with water storage channel in the middle of the plastic hose, the installation cavity bottom is formed with a water storage cavity, the bottom that absorbs water the pipe stretches into in.

In order to solve the problems, the technical scheme adopted by the invention is as follows: a composite cable comprises a cable outer layer and a cable core arranged in the cable outer layer, wherein an oval elastic tube is arranged in the cable outer layer, the long axis of the elastic tube is arranged along the vertical direction, and two end points of the long axis of the elastic tube are fixed on the inner side wall of the cable outer layer; the inner part of the elastic tube is provided with an installation cavity, and a liquid storage cavity is formed between the elastic tube and the cable outer tegument; the liquid storage cavity is provided with a separating mechanism which can separate the liquid storage cavity into an upper part and a lower part; the bottom of the elastic tube is provided with a one-way liquid outlet valve; a water delivery pipe is fixed on the outer side wall of the elastic pipe, the lower end of the water delivery pipe extends to the bottom of the liquid storage cavity, and the upper end of the water delivery pipe extends to the inner top of the elastic pipe; more than one supporting mechanism is arranged in the elastic pipe, and the cable core is limited on the supporting mechanism.
The technical principle of the technical scheme is as follows: the pure water of packing into in advance in the stock solution intracavity below the air cushion, when this composite cable does not receive the extrusion of external force, the pure water is stored in the stock solution chamber below the air cushion, when this composite cable receives decurrent extrusion force, cable ectonexus and elastic tube receive decurrent extrusion force and warp, because the stock solution chamber is separated by the air cushion, consequently, the water in the stock solution intracavity can't get into the stock solution intracavity above the air cushion, consequently, the water in the stock solution intracavity of air cushion below can get into in the transfer line and flow to the top of cable core, then in the space below the cable core of drippage to the installation cavity from the cable core, thereby moisture absorbs the heat dissipation of cable core.
The supporting mechanism is used for supporting the cable core and limiting the cable core, so that the cable core is prevented from being soaked by water.
When the extrusion force disappears, the elastic tube and the outer tegument of the cable reset, part of water in the installation cavity is discharged into the liquid storage cavity through the one-way drain valve, and finally the pressure of the water in the installation cavity and the pressure of the water in the liquid storage cavity reach balance, so that the cable core of the composite cable is prevented from being submerged by the water.
The beneficial effect that this scheme produced is:
1. compared with the existing cable, the existing cable cannot automatically and quickly dissipate heat when not being extruded; and when the cable did not receive the extrusion in this application scheme, when the temperature of cable core leads to the cable core because of reasons such as short circuit is too high suddenly, the elasticity pipe is heated the inflation, steam squeezes water into the cross pipe, the export discharged water of cross pipe lower extreme can dispel the heat to the cable core automatically, after the cable core temperature reduces, the elasticity pipe is no longer heated, the elasticity pipe shrink, the water of bottom in the elasticity pipe is discharged to the stock solution intracavity of air cushion below through one-way drain valve, the circulation heat dissipation is realized in continuous circulation.
