Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figures 1-3, the rat-proof and termite-proof photovoltaic cable of the utility model comprises an outer sheath 2, a central reinforcing member 8 arranged in the center of the cable and a plurality of groups of cables distributed around the central reinforcing member 8, an inner sheath 6 formed by extruding thermoplastic elastomer, a second braided layer 5 formed by metal braiding and a rat repelling cavity 3 are sequentially arranged between the cable and the outer sheath 2 from inside to outside, sealing layers 9 are arranged on the inner side and the outer side of the rat repelling cavity 3, a plurality of supporting blocks 4 distributed in an array are fixedly arranged between the two sealing layers 9, the support blocks 4 extend along the length direction of the cable and divide the rat repelling cavity 3 into a plurality of placing channels, a plurality of partition plates 11 which are arranged at equal intervals are fixedly arranged in the placing channel, the partition plates 11 divide the placing channel into a plurality of placing cavities 12 which are the same in size, and a plurality of pills 10 for driving rats and ants are placed in the placing cavities 12; the outside of oversheath 2 closely laminates first weaving layer 1, first weaving layer 1 adopts the nonmetal weaving that has the peppermint oil to form.

The pill 10 is refined by plant essences of pepper and mint, and the pill 10 with pure natural components avoids causing environmental pollution, does not damage human bodies and avoids being eaten by mistake.

The pills 10 have various diameter specifications, the pills 10 with large diameters are laid on one side, far away from the outer sheath 2, in the placing cavity 12, the pills 10 with small diameters are placed on the pills 10 with large diameters, once the sealing layer 9 on the outer side is bitten by rats and ants, the pills 10 with small diameters roll to the outer portion of the cable firstly, pungent pepper and mint flavors can disperse the rats and ants, and the pills 10 with large diameters are still left in the placing cavity 12.

Second weaving layer 5 adopts copper wire and cellosilk to weave for the material and forms, and the diameter of copper wire and cellosilk is the same, the spindle number is the same, and the weaving opposite direction of tinned copper wire and cellosilk, its weaving density all is not less than 90%, and second weaving layer 5 has improved the intensity of cable, can also avoid continuing the destruction that prevents the rat ant when pellet 10 does not reach the effect simultaneously, protects inside cable.

The first braided layer 1 is woven by Kevlar nonmetal, and the nonmetallic first braided layer 1 improves the protection performance of the surface of the cable.

To sum up, the first braid layer 1 of the rat-and-ant-proof photovoltaic cable of the utility model is soaked with the peppermint oil, so that the whole cable emits the peppermint taste, the rubber taste of the cable is covered, and the probability that rats and ants bite the cable is reduced; when a rat and an ant bite the cable, the first braided layer 1 knitted by the Kevlar nonmetal firstly prevents the rat and the ant from biting by depending on the strength and elasticity of the braiding; when the outer sheath 2 is bitten by the rat and the ant after the first woven layer 1 is broken through and the sealing layer 9 on the outer side is bitten, the pungent taste in the placing cavity 12 flows out to drive the rat and the ant, and when the opening of the sealing layer 9 is enlarged, the pills 10 with small diameter in the placing cavity 12 fall out to give out a large amount of pungent taste to drive the rat and the ant; the second braided metallic layer 5 on the inside also prevents rat and ant biting if the pill 10 still does not repel rat and ant.

Multistage protection against rodents ant structure and the setting of driving away the mouse ant have promoted the ability of cable defense against rodents ant, have replaced metal armor with first weaving layer 1 and second weaving layer 5, have reduced the cost and the weight of cable, have promoted the performance of cable.
