[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, the utility model provides a waterproof and ant-proof medium-voltage power cable, including a core body 1, an outer surface of the core body 1 is provided with an insulating layer 2 for increasing the anti-magnetic interference performance, a silicone layer 3 is fixedly connected to the outer surface of the insulating layer 2, a flexible reinforcement layer 41 is made of polyurethane material, and the inner wall of the silicone layer 3 is provided with a flame retardant coating.

[0022] By setting the insulating layer 2 and the silicone layer 3, the cable works in a humid ground environment for a long time, and the moisture constantly erodes the inside of the core 1. Then the insulating layer 2 and the silicone layer 3 isolate the external moisture and water, thereby improving the waterproofness of the cable.

[0023] like Figures 1 to 4 As shown, the outer surface of the silicone layer 3 is provided with an anti-insect component 4 for increasing protectiveness. The anti-insect component 4 includes a flexible reinforcement layer 41. The inner wall of the flexible reinforcement layer 41 is fixedly connected to the surface of the silicone layer 3. The outer surface of the flexible reinforcement layer 41 is fixedly connected with an anti-ant layer 42. The material of the anti-ant layer 42 is polyvinyl chloride.

[0024] By setting up the insect-proof component 4 and the outer layer 5, during the cable laying process, the cable laying personnel need to pre-bury the cable inside the designated ground. Then, insects and ants have formed around the cable and continuously gnaw on the surface of the outer layer 5. The anti-ant layer 42 and the flexible reinforcement layer 41 isolate and drive away the external pests, thereby conveniently improving the insect-proofness of the cable and avoiding the situation in which the cable is gnawing by pests and the cable is damaged and seriously affects its use.

[0025] like Figures 1 to 4 As shown, an outer layer 5 is fixedly installed on the outer surface of the insect-proof component 4, and connecting rings 6 are fixedly connected to the surface of the outer layer 5 at equal intervals. The outer surface of the connecting ring 6 is coated with an insect-proof paint for isolating ants and insects. The surface of the connecting ring 6 is provided with circular grooves at equal intervals in a circular array, and buffer balls 7 are rotatably connected inside the circular grooves. A waterproof film for increasing waterproof properties is attached to the outer surface of the outer layer 5, and anti-slip strips are fixedly installed on the outer surface of the waterproof film in a circular array at equal intervals.

[0026] When laying the cable, the laying workers can hold the cable by hand, and the anti-slip strips increase the friction between the outer layer 5 and the laying workers' hands. Then the laying workers drag the outer layer 5 along the ground, and the buffer balls 7 touch the ground in advance, which increases the sliding properties of the buffer balls 7 and reduces the damage caused by the friction between the outer layer 5 and the ground.

[0027] The working principle and use process of the utility model are as follows: first, during the cable laying process, the laying personnel can hold the cable by hand, and the anti-slip strip increases the friction between the outer layer 5 and the laying personnel's hand, and then the laying personnel drags the outer layer 5 along the ground, and then the buffer ball 7 touches the ground in advance, so that the buffer ball 7 increases the sliding property, and then the cable is placed in the pre-buried position. After the cable is laid, insects and ants have been generated around the cable for a long time and continuously gnaw on the surface of the outer layer 5, and the anti-ant layer 42 and the flexible reinforcement layer 41 isolate and drive away external pests. Finally, the cable works in a humid environment on the ground for a long time, and its moisture continuously erodes the inside of the core 1, and then the insulating layer 2 and the silica gel layer 3 isolate the external moisture and water, thereby improving the waterproofness of the cable.
