Embodiment 1

[0029] refer to Figure 1~4 , a power cable protection assembly, including a cable body 1, a protective sleeve 2 arranged outside the cable body, and a support mechanism arranged outside the protective sleeve,

[0030] The cable body 1 is sequentially composed of an aluminum alloy guide core 101, an insulating layer 102, an inner lining layer 103, a water blocking layer 104, a metal sheath 105, an outer sheath 106 and an anti-corrosion layer 107 from the inside to the outside. The anti-corrosion layer consists of Made of anti-corrosion material, the anti-corrosion material is made of the following raw materials in parts by weight: 60 parts of glycerol, 16 parts of nano-zinc oxide, 0.6 part of coupling agent, 0.06 part of polydienylpropylenedimethylammonium chloride, 3 parts of polyacrylate, 6 parts of chloroform, 9 parts of titanium dioxide, 4 parts of polyvinyl alcohol, 7 parts of manganese trioxide, 0.06 parts of tributyl phosphate, 6 parts of ammonium polyacrylate, 11 parts...

Embodiment 2

[0039] refer to Figure 5~6 , the power cable protection assembly described in this embodiment is an improvement made on the basis of Embodiment 1, wherein:

[0040] Several pillars 13 are arranged on the base plate, and arc-shaped grooves 14 are arranged on the pillars, the distance from the lowest point of the arc-shaped grooves to the base plate is equal to the distance from the highest point of the rotating shaft to the base plate, The inner surface of the arc-shaped groove is adapted to the outer surface of the protective sleeve.

[0041] The number of the pillars is set according to the length of the actual cable body, for example, one is set for 1 meter, or one is set for 2 meters, etc.; the inner surface of the arc-shaped groove is adapted to the shape of the outer surface of the protective sleeve, The protection sleeve and the cable body are auxiliary supported to share part of the force of the rotating shaft.

Embodiment 3

[0043] The power cable protection assembly described in this embodiment is basically the same as that in Embodiment 1, except that:

[0044] The anti-corrosion material is made of the following raw materials in parts by weight: 50 parts of glycerol, 14 parts of nano-zinc oxide, 0.5 parts of coupling agent, 0.04 parts of polydienyl propylene dimethyl ammonium chloride, and 2 parts of polyacrylate , 5 parts of chloroform, 8 parts of titanium dioxide, 3 parts of polyvinyl alcohol, 6 parts of manganese trioxide, 0.02 parts of tributyl phosphate, 5 parts of ammonium polyacrylate, 7 parts of polyvinylidene fluoride, N,N-dimethyl 2 parts of methyl formamide, 15 parts of deionized water.

[0045] The coupling agent is tetraisopropyl bis(dioctylphosphite acyloxy) titanate coupling agent, CAS No.: 65460-52-8, molecular formula: C44H98O10P2Ti, which is commercially available.

[0046] The polyacrylate is polymethyl methacrylate and polymethyl acrylate, and the ratio of polymethyl methac...

Abstract

The invention provides a power cable protection assembly, and belongs to the technical field of a cable. The power cable protection assembly comprises a cable body, a protection sleeve and a supporting mechanism; the cable body consists of an aluminum alloy conductive core, an insulating layer, an inside liner layer, a water-blocking layer, a metal sheath, an outer protection layer and a corrosionresistant layer from inside to outside in sequence; flexible arc-shaped convex strips are uniformly arranged on the inner surface of the protection sleeve at intervals in the longitudinal direction;the longitudinal sections of the flexible arc-shaped convex strips are waveform; through holes are formed, among the flexible arc-shaped convex strips, in the protection sleeve; a filtering net is arranged on the through holes; the supporting mechanism comprises a bottom plate and vertical plates arranged on the two sides of the bottom plate; a first groove is formed in the bottom plate; a rotaryshaft is arranged between the vertical plates in an interval manner; the rotary shaft is partially arranged in the first groove and is in smooth contact with the inner surface of the first groove; andthe top parts of the vertical plates are sealed through a cover plate. The comprehensive performance of the power cable protection assembly is improved and the cable construction difficulty can be lowered, so that the cable can be protected from natural damage or man-made sabotage.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a power cable protection component. Background technique [0002] A cable is a wire made of one or more mutually insulated conductors surrounded by an insulation and a protective layer, and is used to transfer power or information from one place to another. Underground cables, compared to common overhead lines, are often buried underground. Unlike elevated high-voltage lines, cables are often laid in cable trenches, tunnels, pipelines or indoors. After entering the modern society, due to the shortage of urban land, heavy traffic pressure, city appearance construction and other reasons, large cities generally adopt underground cable transmission. Due to the underground environment, underground cables are easily damaged or corroded. Therefore, most underground cables are installed in pipelines, which are used to isolate the external environment, so as to achieve the pu...
