Description

Technical Field

[0002] Cables are important transmission media in circuits. Due to different transmission volumes, the volumes of cables vary. During the cable laying process, due to restrictions from the upper environment, most cables are installed underground so as not to affect the aesthetics above the ground. After entering modern society, due to reasons such as tight urban land use, heavy traffic pressure, and urban appearance construction, underground cable power transmission methods are generally adopted in large cities. Underground cables can mainly transmit electric energy and control signals.

[0003] In the patent with the publication number CN212809818U, an underground cable that can prevent being bitten by insects is disclosed, which includes a cable insulating layer, a filling layer, a core body, and an outer protective layer. A filling layer is arranged inside the cable insulating layer, a core body is arranged inside the filling layer, and a fixing ring is nested outside the cable insulating layer. An outer protective layer is bonded to the outside of the fixing ring. A first through-hole is formed on the surface of the outer protective layer, a second through-hole is arranged below the first through-hole, and a sealing ball is fitted inside the second through-hole.

[0004] In the above technology, the separated space can be filled with insecticide. The liquid insecticide will flow out to kill pests after the outer protective layer is broken. However, after the liquid insecticide flows out, it may chemically react with the soil and water, thereby changing the composition and properties of the insecticide, further affecting its insecticidal effect, and also reducing the insect-proof performance of the underground cable. Therefore, innovation is made on this technology. Content of the Utility Model

[0005] The purpose of the utility model is to provide an underground cable that can prevent being bitten by insects, so as to solve the problem that after the liquid insecticide flows out, it may chemically react with the soil and water, thereby changing the composition and properties of the insecticide as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An underground cable that can prevent being bitten by insects, including a core. One end of the core is sleeved with an insulating layer, one end of the insulating layer is sleeved with a flame-retardant layer, one end of the flame-retardant layer is sleeved with a moisture-proof layer. A plurality of reinforcing ribs are arranged on the outer surface of the moisture-proof layer. A compression-resistant layer is arranged outside the plurality of reinforcing ribs. One end of the compression-resistant layer is sleeved with a corrosion-resistant layer. One end of the corrosion-resistant layer is sleeved with a brass strip. A fiberglass pipe layer is arranged outside the brass strip.

[0007] As a preferred technical solution of the utility model, one end of the brass strip is sleeved with an ultraviolet-resistant layer, and the fiberglass pipe layer is sleeved on one end of the ultraviolet-resistant layer.

[0008] As a preferred technical solution of the present utility model, the anti-ultraviolet layer is fixedly sleeved on one end of the brass strip, and an anti-ant coating is applied on the surface of the fiberglass pipe layer.

[0009] As a preferred technical solution of the present utility model, the thickness of the brass strip is greater than that of the anti-ultraviolet layer.

[0011] As a preferred technical solution of the present utility model, the positions where multiple said reinforcing rib strips are arranged are arranged at equal intervals.

[0012] As a preferred technical solution of the present utility model, one end of the brass strip is fixedly sleeved with the corrosion-resistant layer, and one end of the corrosion-resistant layer is fixedly sleeved with the compression-resistant layer.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For an underground anti-insect bite cable of the present utility model, by providing a flame-retardant layer, reinforcing rib strips, a brass strip, an anti-ultraviolet layer, a fiberglass pipe layer and an anti-ant coating, the flame-retardant layer is made of antimony trioxide material, which can inhibit and delay combustion and is not easily combustible itself.

[0015] 2. For an underground anti-insect bite cable of the present utility model, by providing a moisture-proof layer, a compression-resistant layer and a corrosion-resistant layer, the moisture-proof layer is made of chloroprene rubber material, which can prevent the penetration and erosion of liquids and extend the service life of the wire core.

[0027] Working principle: The cable is an important transmission medium in the circuit. Due to different transmission amounts, the volume of the cable also varies. During the cable laying process, due to the upper environment limitations, the cable is mostly installed underground, so as not to affect the beauty above the ground.

The anti-ant coating 11 contains a relatively strong smell, which can prevent insects from approaching the cable. The moisture-proof layer 4 is made of chloroprene rubber material, which can prevent the penetration and erosion of liquids and extend the service life of the core 1. The corrosion-resistant layer 7 is made of heat-resistant alloy and has excellent oxidation resistance and corrosion resistance, increasing the applicable range of the cable.
