Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a corrosion-resistant high-voltage cable. Background Technology

[0002] Corrosion-resistant high-voltage cables are cables used to transmit high-voltage electricity. They can operate stably under high voltage, effectively reducing energy loss during power transmission, enabling long-distance, high-capacity power transmission. Their excellent corrosion resistance ensures the continuity and stability of power transmission in complex and harsh environments, reducing power outages caused by cable failures.

[0003] Chinese Patent CN218069405U discloses a moisture-proof and corrosion-resistant high-voltage cable, comprising a hollow cable shell and moisture-proof sealing heads at both ends of the cable shell. Both ends of the cable shell are fitted with coaxially arranged external threaded connectors. One end of each moisture-proof sealing head is fitted with an internal threaded connecting sleeve that is threaded to and matches the size of the external threaded connector. The cable shell includes a metal armor layer, the outer wall of which is coated with a corrosion-resistant paint layer. Multiple sets of high-voltage cables are housed within the cable shell. The moisture-proof sealing heads at both ends of the cable shell effectively seal the ends, achieving a moisture-proof effect. The threaded connection between the moisture-proof sealing heads and the external threaded connectors facilitates installation and disassembly. The metal armor layer increases strength, and the corrosion-resistant paint coating on the surface of the metal armor layer enhances corrosion resistance and extends service life.

[0004] However, the above technical solution has the following shortcomings: Although the cable can seal the end of the outer shell, sometimes the distance between two cables is relatively close. Under the action of external wind, the cables may be blown out of place, which will destroy the stable and safe distance between the cables. The interaction of electric fields will accelerate the aging and damage of the cables. Utility Model Content

The stabilizing mechanism is mounted on the cable body and includes three sets of linearly arrayed socket components, a connecting plate and a mating plate with slots mounted on the socket components, an insert plate with multiple linearly arrayed positioning slots mounted on the connecting plate, multiple locking blocks disposed inside the slots, a first bolt penetrating the connecting plate and the insert plate, and a first nut threaded onto the first bolt. The mating plate has an elongated hole through which the first bolt passes, the first nut and the mating plate abut against each other, and the locking blocks and positioning slots are mutually compatible.

[0007] Preferably, the cable body includes an outer sheath, a metal armor layer disposed inside the outer sheath, an inner sheath disposed inside the metal armor layer, a wrapping tape disposed inside the inner sheath, a filler material disposed inside the wrapping tape, three insulating shielding layers disposed inside the filler material, an insulating layer disposed inside the insulating shielding layers, a conductor shielding layer disposed inside the insulating layers, and a conductor disposed inside the conductor shielding layers.

[0008] Preferably, the filler is provided with a support member that divides it into three equal regions, with the three conductors located in different regions.

[0009] Preferably, the socket assembly includes two hinged first semicircular rings, two hinged second semicircular rings, and a fixing assembly disposed on the first and second semicircular rings; a connecting plate and a mating plate are respectively disposed on the first and second semicircular rings.

[0010] Preferably, the fixing component includes connecting lugs disposed on the first semicircular ring and the second semicircular ring, two second bolts passing through the connecting lugs, and a second nut threaded onto the second bolts; both the second bolts and the second nut abut against each other with the connecting lugs.

[0012] Preferably, a reinforcing block is connected between the first semicircular ring and the second semicircular ring, and a reinforcing block is connected between the second semicircular ring and the first semicircular ring.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] The stabilizing mechanism is mounted on the cable body 1 and includes three sets of linearly arrayed socket components, a connecting plate 13 mounted on the socket components and a docking plate 15 with slots 18, an insert plate 16 mounted on the connecting plate 13 and having multiple linearly arrayed positioning slots 17, multiple locking blocks 19 mounted inside the slots 18, a first bolt 21 penetrating the connecting plate 13 and the insert plate 16, and a first nut 22 threaded onto the first bolt 21; the docking plate 15 is provided with an elongated hole 20 for the first bolt 21 to pass through, the first nut 22 and the docking plate 15 abut against each other, and the locking blocks 19 and the positioning slots 17 are adapted to each other.

[0023] The socket assembly includes two hinged first semicircular rings 12, two hinged second semicircular rings 14, and a fixing assembly disposed on the first semicircular rings 12 and the second semicircular rings 14; the connecting plate 13 and the mating plate 15 are respectively disposed on the first semicircular rings 12 and the second semicircular rings 14; the fixing assembly includes connecting lugs 23 disposed on the first semicircular rings 12 and the second semicircular rings 14, two second bolts 24 penetrating the connecting lugs 23, and a second nut 25 threadedly connected to the second bolts 24; the second bolts 24 and the second nut 25 both abut against the connecting lugs 23.

[0024] Multiple equidistant protrusions 26 are provided on both the first semicircular ring 12 and the second semicircular ring 14. The protrusions 26 are made of elastic anti-slip material. A reinforcing block 27 is connected between the first semicircular ring 12 and the second semicircular ring 14. The reinforcing block 27 is used to connect the sleeve assembly, improve the structural strength of the stabilizing mechanism, and thus ensure the isolation effect on the cable body 1.

[0025] In this embodiment, when the stabilizing mechanism needs to be installed, the first semicircular ring 12 and the second semicircular ring 14 are first opened by the hinge, and then clamped on the outside of the cable body 1. The second bolt 24 is then passed through the connecting lug 23, and the second nut 25 is screwed onto the second bolt 24, thus fixing the first semicircular ring 12 and the second semicircular ring 14 onto the cable body 1. The convex strip 26, which is provided in conjunction with the stabilizing mechanism, can both improve the stability of the first semicircular ring 12 and the second semicircular ring 14 and prevent wear on the surface of the cable body 1. Then, a suitable fitting length is selected. Align the insert plate 16 on the connecting plate 13 with the locking block 19 in the slot 18 and insert it. Then, insert two first bolts 21 through the connecting plate 13, the insert plate 16 and the elongated hole 20. Finally, screw the first nut 22 onto the first bolts 21 to complete the fixing of the connecting plate 13 and the docking plate 15. The locking block 19 can improve the tightness of the connection, prevent the cable body 1 from being too close together under the action of wind, reduce the wear of the cable body 1 caused by the electric field force, ensure the service life of the cable body 1, and is simple to operate and has good practicality.

The filler 7 is provided with a support member 6 that divides it into three equal regions, and the three conductors 11 are located in different regions.

[0028] In this embodiment, the outer sheath 2, the metal armor layer 3, and the inner sheath 4 provide the cable body 1 with good corrosion resistance, tensile strength, and compressive strength, while also enhancing mechanical strength and preventing moisture from entering the internal structure. The filler 7, in conjunction with the supporting member 6, fills the gaps inside the cable body 1, making the shape round and the structure stable, and ensuring uniform stress during manufacturing and laying. The insulating shielding layer 8 and the conductor shielding layer 10 are used for electrical insulation and isolation of the electromagnetic field between the internal conductors 11, respectively.
