The drawings are schematic illustrations of the implementation of the present invention to facilitate understanding of the principles of structural operation. The specific product structure and the proportional size are determined according to the use environment and the conventional technology. The invention has convenient drawing, and all the layers wrapped outside the venom layer are generally called outer skin layers, and the inner side of the venom layer is generally called cable cores, and each cable core comprises a conductor core and an inner skin layer wrapped outside the conductor core. The inner skin layer in the invention comprises a layer with various functions in a venom layer such as a conductor shielding layer and an insulating layer in a cable for releasing gnawing like CN 209056305.

The electric drive module 30 of the present invention is known in the art and is mainly composed of a motor, a reducer and a control unit.

The electric parameters between two venom seal pots above two adjacent connection points are detected through professional electric detection equipment, the area where the leakage point of the venom in the venom layer 3 on the cable is located is judged according to the electric signal displayed on the detection equipment, and finally, the damage point of the venom layer 3 bitten by organisms on the cable is found out by carpet type investigation on the area range. The soil in the region between two adjacent venom pipes 5 can be detected by a professional tool, the leakage point of the venom is judged according to the pollution degree of the soil, and the venom layer 3 is repaired after the damage point is found.

The damping ring 35 in the invention adopts the prior art, and the damping ring 35 is used for ensuring that the abrasive belt 34 can be effectively tightened in the process of winding the abrasive belt 34 on the cable by the winding mechanism 13, so that the abrasive belt 34 is tightly wrapped at the connecting point of the cable.

The working process of the invention is as follows: when the invention needs to be cut, the steel saw is directly used for cutting, and due to the internal structural characteristics of the venom tube 5 of the venom layer 3 inside, when the venom tube 5 in the venom net sleeve 4 is cut off, the venom absorbed in the hair absorbing material 37 in the venom tube 5 cannot drip and leak, so that the environmental pollution caused by the leakage of the venom is avoided, and the invention is convenient to cut randomly.

When two sections of the cable connecting end are required to be connected, the outer skin layer 1 and the venom layer 3 of the connecting ends of the two sections of cables are removed by a certain length, the connecting ends of the conductor cores are exposed, and the two sections of conductor cores are in butt joint connection through the connecting piece. The end surface of the venom layer 3 with a certain length removed at one end is provided with an exposed annular convex surface of the venom net sleeve 4, and the two sides of the venom connecting layer 7 with the length matched with the distance between the venom layers 3 on the outer sides of the two sections of cables are provided with slots 10 matched with the exposed annular convex surface of the venom net sleeve 4.

After the exposed ends of two sections of cables connected by the connecting piece are sequentially wrapped by the insulating layer and the shielding layer, the two sections of conductor cores connected by the connecting piece are curled and wrapped by the matched venom linking layer 7, and the buckling teeth 8 at the two ends of the venom linking layer 7 are buckled and connected. After the venom connection layer 7 is curled and formed, the connecting glue is extruded into the gap between the buckling teeth 8 at the two sides of the venom connection layer 7, so that the buckling teeth 8 at the two ends of the venom connection layer 7 are mutually adhered without being separated.

Annular slots 10 formed on two sides of the curled venom linking layer 7 are respectively inserted with exposed annular convex surfaces of the venom net sleeve 4 on the cable on the same side, so that the venom net sleeve 4 is effectively linked with the hair absorbing layer 12 in the venom linking layer 7, and the venom adsorbed by the hair absorbing layer 12 in the venom linking layer 7 can permeate and supplement into the hair absorbing material 37 in the venom tube 5 through the fracture of the venom net sleeve 4.

An abrasive belt 34 is wound on the outer side of the toxic liquid joining layer 7 which effectively joins the toxic liquid layers 3 on the outer sides of the two sections of conductor cores 2, a layer of adhesive tape is wound on the outer side of the wound abrasive belt 34, rubber mud which permeates liquid is filled into the abrasive belt 34 through a funnel inserted into the abrasive belt 34, the liquid rubber mud entering the abrasive belt 34 is completely sealed in the abrasive belt 34 by the adhesive tape, and the connection of the two sections of cables can be completed after the rubber mud permeating into the abrasive belt 34 is solidified.

After the cables are connected, the venom linking layer 7 on each connecting point of the cables is communicated with a sealed venom tank positioned above the connecting point through a hose arranged at a liquid inlet hole 11 on the connecting layer so as to supplement venom to the hair absorbing layer 12 in the corresponding venom linking layer 7 and the part bitten by organisms. According to the invention, after the cable connection is finished, the venom is filled, so that the seepage of the venom in the cable connection and cutting processes is avoided.

During the cable connection process, the sanding belt 34 is wound around the connection point of the cable using the winding mechanism 13. The electric drive module 30 is started firstly, the electric drive module 30 drives the arc sleeve C19 and the arc sleeve D20 in the closed state to rotate relative to the arc sleeve A14 and the arc sleeve B15 through the gear D29, the gear C28, the gear B26, the gear A24 and the arc rack A22 and the arc rack B23 in the closed state, and when the arc sleeve C19 rotates to the range of the arc sleeve B15, the electric drive module 30 stops running.

Unlocking catch a17 and opening arc sleeve B15, unlocking catch B21 and opening arc sleeve D20 outward. The circular arc sleeve C19 and the circular arc sleeve D20 are sleeved outside the venom connecting layer 7 at the connecting point of the invention, and one end of the abrasive belt 34 wound on the winding roller 33 is wound and adhered on the venom connecting layer 7 through connecting glue. Then, the arc sleeve D20 is closed to the arc sleeve C19 and locked by the catch B21, and the arc sleeve B15 is closed to the arc sleeve a14 and locked by the catch a 17. Starting the electric drive module 30, the electric drive module 30 drives the arc sleeve C19 and the arc sleeve D20 to rotate in the arc sleeve A14 and the arc sleeve B15 through a series of transmission, the arc sleeve A14 drives the winding roller 33 to revolve around the connection point of the invention through two supports B31 and a rotating shaft B32, the abrasive belt 34 wound on the winding roller 33 winds towards the connection point of the invention, and the winding mechanism 13 is repeatedly moved under the action, so that the abrasive belt 34 completely winds and wraps the exposed part of the venom layer 3 and the venom connecting layer 7 at the connection point of the invention and reaches a certain thickness. During winding of the sanding belt 34, since the damping ring 35 for slowing down the rotation speed of the rotating shaft B32 relative to the support B31 is installed between the rotating shaft B32 and the support B31, the sanding belt 34 is always in a tight state during winding to the connection point of the present invention, so that the sanding belt 34 is tightly wound at the connection point of the present invention. After the abrasive belt 34 is wound, the operation of the electric driving module 30 is stopped and the abrasive belt 34 is cut off, so that the process of winding the abrasive belt 34 on the connection point can be completed.

After the winding mechanism 13 is used, the arc sleeve B15 and the arc sleeve D20 are opened in sequence, the winding mechanism 13 is removed from the winding mechanism, and after the winding mechanism 13 is removed from a connecting point of the winding mechanism, the arc sleeve D20 and the arc sleeve B15 are closed in sequence.

In conclusion, the beneficial effects of the invention are as follows: in the venom net sleeve 4 in the venom layer 3, due to the fact that the capillary material adsorbing the venom is filled in the venom net sleeve, in the cutting and connecting process, the venom is not filled in the venom net sleeve, the venom can not drop and leak along with the cutting of the venom net sleeve 4, and the cable can be cut effectively. Meanwhile, compared with a cable which is released and gnawed under the publication number of CN209056305, the venom net sleeves 4 in the invention are dense in structure and do not have venom protection dead angles, so when a mouse and an insect bite the cable, the venom net sleeves 4 in the venom layer 3 must be firstly damaged to further damage a shielding layer and an insulating layer. Along with the fact that the venom net sleeve 4 is bitten and broken by the mouse and the insect, the venom adsorbed on the hair absorbing material 37 in the venom tube 5 can be contacted by the mouse and the insect, and therefore the biological biting prevention effect of the venom tube is effectively achieved. In addition, when the upper mouse and the insect damage the venom tube 5 in the venom net 4, the venom tube 5 is torn from the spiral cross lines 6 by the mouse and the insect along with the biting of the mouse and the insect, and after the mouse and the insect stop further biting due to the action of the venom oozed by the venom tube 5, the skin torn by the mouse and the insect on the venom tube 5 can automatically close the fracture opening, so that the venom in the venom tube 5 is prevented from continuously oozing, the loss of the venom in the venom layer 3 is reduced, and the function of the troops biting is continuously and effectively exerted.

Along with the leakage of the venom at the fracture opening in the venom layer 3, the venom in a venom sealing tank with the connection point communicated with the corresponding venom linking layer 7 permeates and supplements into the venom pipe 5 in the venom layer 3 through the hair absorbing layer 12 in the venom linking layer 7, so that the biological bite prevention effect is continuously exerted, the biological bite loss of the cable is reduced, and the cable maintenance cost is reduced.
