Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a flame-retardant and corrosion-resistant cable insulation protective sleeve. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, used to connect circuits, electrical appliances, etc. Cables can be divided into DC cables and AC cables according to the system of photovoltaic power stations. When cables are used in different scenarios, in order to extend the service life of the cables, protective covers are often put on the surface of the cables to protect them.

[0003] For example, the Chinese patent with publication number CN210015731U3 discloses a corrosion-resistant flame-retardant protective sleeve for mining control cables, including a sleeve core layer, a spacer block is fixedly connected to the outside of the sleeve core layer, and a first filling groove is reserved between the spacer block and the inside of the sleeve core layer, an anti-corrosion layer is fixedly connected to the outside of the spacer block, and a second filling groove is reserved between the anti-corrosion layer and the spacer block, a protective layer is fixedly connected to the outside of the anti-corrosion layer, and an anti-corrosion coating is coated on the outside of the protective layer, the first filling groove is filled with a first filler, and the second filling groove is filled with a second filler. The corrosion-resistant flame-retardant protective sleeve for mining control cables makes the protective sleeve waterproof, while increasing the stability of the internal structure of the cable, and increasing the flame retardancy and corrosion resistance of the cable, thereby increasing the overall practicality.

[0004] Although the above example can improve the anti-corrosion effect of the cable to a certain extent during use, in actual use, when the protective cover is subjected to excessive pressure, the protective cover will deform and squeeze the cable inside, which may easily cause the cable to be squeezed and damaged, resulting in certain inconveniences in use. At the same time, when the protective cover is put on the surface of the cable, the rubber on the surface of the cable and the inner wall of the protective cover rub against each other, which will generate greater friction, making it difficult for the protective cover to be put on the surface of the cable, resulting in certain inconveniences in use.

At the same time, the corners of the reinforcing tripod are rounded to prevent the tripod from piercing the protective sleeve body when a force is applied. The pressure reinforcing wire adopts the bending resistance of a magnesium alloy, so that the protective sleeve can still have good softness when bent. The lubricating block is set so that when the protective sleeve is sheathed on the surface of the cable, the rubber on the surface of the cable contacts the lubricating block. Under the action of friction between the rubber and the lubricating block, talcum powder is attached to the surface of the rubber to lubricate the surface of the cable, so that the protective sleeve is easier to sheath on the surface of the cable.

[0025] In this embodiment, during use, the corrosion resistance of the protective cover body 1 is enhanced by the anti-corrosion coating 2, so that the anti-corrosion effect is better. The protective cover body 1 is made of rubber material, so that it has a good insulation effect. At the same time, the bottom line conductor is set so that the current can be introduced into the bottom line when leakage occurs in the cable. The tension reinforcement rib 3 is set and the tensile resistance of nylon is utilized to make the protective cover have good tensile resistance, making it easier to use.

[0026] Example 2

[0027] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the inner wall of the sleeve layer 9 is fixedly connected with a lubricating block 10, one side of the lubricating block 10 is overlapped with a cable rubber 11, a conductor 12 is arranged inside the cable rubber 11, and a filling strip 13 is arranged inside the conductor 12. The protective sleeve body 1 is made of rubber material with a thickness of 5mm-10mm, the anti-corrosion coating 2 is sprayed on the surface of the protective sleeve body 1 with a polyethylene anti-corrosion coating, the tensile reinforcement ribs 3 are made of nylon wire with a thickness of 1mm-2mm, and the number is 6, and the ground conductor 4 is made of copper wire with a thickness of 1.5mm-2mm.

[0028] In this embodiment, by arranging the pressure reinforcing wire 5 and the reinforcing tripod 6, the folding resistance of the magnesium alloy and the high hardness of the titanium alloy are utilized to make the overall pressure resistance of the protective sleeve better. At the same time, the protective sleeve still has good softness when it is bent. The storage tank 7 is filled with halogen-free flame retardant, which can play a good flame retardant role when the protective sleeve burns, making it easier to use.

[0029] Example 3

[0030] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the pressure reinforcement wire 5 is made of magnesium alloy material with a thickness of 0.2mm-0.5mm, and the number is 2 groups, with 3 wires in each group; the reinforcing tripod 6 is made of titanium alloy material with 2 groups, and the corners are rounded; the interior of the storage tank 7 is provided with a halogen-free flame retardant; the thermal insulation layer 8 is made of polyimide with a thickness of 1mm-2mm; the lubricating block 10 is pressed into a block with talcum powder and embedded in the inner wall of the socket layer 9.

[0031] In this embodiment, when the protective sleeve is put on the cable surface, the cable surface is not in direct contact with the sleeve layer 9 under the action of the lubricating block 10.

The protective sleeve body 1 adopts the setting of rubber material to have a good insulation effect. At the same time, the setting of the bottom line conductor allows the cable to conduct current into the bottom line when leakage occurs. The setting of the tension reinforcement rib 3 utilizes the tensile resistance of nylon to make the protective sleeve have good tensile resistance, making it easier to use. The setting of the pressure reinforcement wire 5 and the reinforcement tripod 6 utilizes the folding resistance of magnesium alloy and the high hardness of titanium alloy to make the overall pressure resistance of the protective sleeve better. At the same time, the protective sleeve still has good softness when it is bent. The storage tank 7 contains halogen-free flame retardant, which can play a good flame retardant role when the protective sleeve burns, making it easier to use.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
