[0002] Currently, to ensure the corrosion resistance and safety requirements of buried cables, the cables are usually laid underground after passing through conduits, thus overcoming the technical obstacles in the cable manufacturing process.

[0003] The existing protective pipes for underground cables have insufficient compressive strength, which makes them prone to cracking when run over by heavy vehicles or when the soil settles, thus damaging the cables. In addition, when multiple cables are installed in one protective pipe, the close proximity between them can easily lead to heat accumulation, which can also damage the cables. Utility Model Content

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the cable protection pipe is provided with a composite layer structure, which includes, from the outside to the inside, a pressure-resistant layer, a moisture-proof layer and an anti-corrosion layer.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0016] See attached diagram. Figures 1 to 4 In this embodiment, a buried pressure-resistant cable includes several cable bodies 1, cable mounting bases, and cable protection pipes 2. The cable mounting base includes an inner support column 3, and both ends of the inner support column 3 are provided with cable limiting structures. The cable protection pipe 2 is sleeved on the outer periphery of the cable mounting base, and both ends of the cable protection pipe 2 are respectively provided with a first fixing plate 20 and a second fixing plate 21. Several outer support columns 6 are provided between the first fixing plate 20 and the second fixing plate 21.

[0017] Specifically, the cable limiting structure includes a fixed seat 30 fixed to the end of the inner support column 3, an arc-shaped limiting plate 31 on the fixed seat 30, an eccentric pressing plate 4 movably arranged on one side of the arc-shaped limiting plate 31, a locking bolt 40 on the eccentric pressing plate 4, a threaded groove on the fixed seat 30, and the locking bolt 40 rotatably connected to the threaded groove; a cable fixing sleeve 5 is detachably installed on the outer wall of the arc-shaped limiting plate 31, and a number of limiting grooves 50 are provided on the cable fixing sleeve 5.

[0019] Preferably, the cable protection pipe 2 is provided with a composite layer structure, which includes, from the outside to the inside, a pressure-resistant layer 22, a moisture-proof layer 23, and an anti-corrosion layer 24. The pressure-resistant layer 22 enhances the strength of the outer structure, the moisture-proof layer can prevent moisture from the soil from entering and avoid short circuits caused by moisture in the cable, and the anti-corrosion layer can resist the erosion of underground acid and alkali substances and extend the service life of the cable.

[0020] Specifically, a gap 25 is reserved between two adjacent cable bodies 1. The gap 25 between adjacent cable bodies 1 provides heat dissipation space for the cable to generate heat, avoiding accelerated aging of the insulation layer due to heat accumulation, and also reduces friction and wear between the cables.

[0021] In one possible implementation, a limiting groove is also provided on the inner wall of the cable protection pipe 2.

[0023] In use, first, several cable fixing sleeves 5 are placed on the outside of the arc-shaped limiting plate 31, then the cable body 1 is placed in the limiting groove 50 on it, then the cable protection tube 2 is placed on the outer periphery of the cable fixing seat, and then the locking bolt 40 is rotated to make the eccentric pressing plate 4 rotate. The eccentric pressing plate 4 can press the cable body 1 and limit it between the inner wall of the cable protection tube 2 and the cable fixing sleeve 5.

[0024] The inner support column 3 in the cable mounting base and the outer support column 1 form a support structure, which can effectively distribute the ground pressure load, prevent the cable from deforming or breaking due to compression, and improve the overall structure's impact resistance and crush resistance.
