Description

Technical Field

[0001] This invention relates to the field of overhead cable technology, and more particularly to a lightweight and wear-resistant overhead cable. Background Technology

[0002] Overhead transmission cables play a vital role in power transmission lines, serving as the carriers of electricity. During rainy and snowy weather in autumn and winter, ice can condense on the surface of the cables, compromising the safety of power transmission and increasing the risk of cable breakage or short circuits. This disrupts normal power transmission and causes significant losses to the transmission operation.

[0003] The existing overhead cables (announcement number: CN205827997U) have at least the following drawbacks: The above patent uses an electric heating wire to heat the cable to remove snow, ice, and frost, reduce the cable load, and ensure the safety of cable power transmission; however, relying solely on the electric heating wire to melt the snow can easily lead to a slow melting speed and make it difficult to remove large snow piles, thus affecting the snow removal effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lightweight and wear-resistant overhead cable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightweight and wear-resistant overhead cable includes a cable body and further includes:

[0007] A vibration mechanism is installed on the outside of the cable body and is used to vibrate and de-ice when ice forms on the surface of the cable body.

[0008] The vibration mechanism includes a fixed ring, which is installed on the outside of the cable body, and a vibration component is rotatably installed on the outer periphery of the fixed ring;

[0009] The heating wire is installed inside the cable body and is used to heat the surface of the cable body. The retaining ring is made of a thermally conductive material.

[0010] As a further embodiment of the present invention, the vibration assembly includes a rotating ring, which is rotatably mounted on the outer periphery of a fixed ring. The rotating ring has a U-shaped cross-section. A roller is rotatably mounted on one inner wall of the rotating ring, and an eccentric column is eccentrically fixed on the outer surface of the roller away from the rotating ring.

[0011] As a further embodiment of the present invention, the rotating ring has a rectangular opening through the inner circumference of the roller, the outer circumference of the roller is in contact with the outer surface of the fixed ring, and the roller can roll around the outer circumference of the fixed ring as the rotating ring rotates.

[0012] As a further embodiment of the present invention, a power assembly is also installed inside the rotating ring. The power assembly includes a closed ring fixedly installed on the outer periphery of the rotating ring. Multiple strip-shaped openings are uniformly opened through the outer periphery of the closed ring, and a blade is slidably installed on the inner wall of each strip-shaped opening.

[0013] As a further embodiment of the present invention, a connecting plate is fixedly installed at one end of the blade near the fixed ring, an annular airbag is fixedly installed on the inner wall of the rotating ring, and the connecting plate is fixedly installed on the outer surface of the annular airbag.

[0014] As a further embodiment of the present invention, two limiting rings are fixedly installed on the outer periphery of the fixed ring, and the rotating ring is rotatably installed between the two limiting rings.

[0015] As a further embodiment of the present invention, the outer circumference of the fixing ring is uniformly provided with a plurality of threaded holes, and the inner wall of each threaded hole is threaded with a locking bolt.

[0016] As a further embodiment of the present invention, the cable body is composed of a cable core, a load-bearing wire, an insulating shielding layer and a protective sleeve, and the heating wire is disposed between the insulating shielding layer and the protective sleeve.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The surface of the cable body is heated by an electric heating wire to melt the snow and prevent the snow from damaging the cable body;

[0019] 2. When the heating wire is heated to a certain temperature, the heat will be conducted through the fixed ring to the annular airbag installed inside the rotating ring, causing the gas inside the annular airbag to expand due to the heat. This expansion of the annular airbag will push the connecting plate and the blade outward, allowing the blade to extend to the outside of the closed ring. This will allow the rotating ring and the blade to cooperate to form a fan blade structure, so that the rotating ring can be driven to rotate as a whole under the action of external wind. As the rotating ring rotates, it will drive the roller to roll around the outer circumference of the fixed ring. Since the roller is equipped with an eccentric column, the roller will vibrate when it rolls, which will cause the rotating ring and the fixed ring to drive the cable body to vibrate, so as to shake off the snow remaining on the surface of the cable body and improve the snow removal effect.

[0020] 3. After the snow on the surface of the cable body is cleared, turn off the power to the heating wire to stop heating the surface of the cable body. This allows the gas inside the annular airbag to cool and contract, causing the contracted annular airbag to drive the blade plate back into the swivel through the connecting plate. This prevents the swivel from rotating continuously and causing the cable body to shake for a long time, which would affect the stability of the cable body connection. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] See attached document Figure 1 - Appendix Figure 7 A lightweight and wear-resistant overhead cable includes a cable body 1, and further includes:

[0032] A vibration mechanism is installed on the outside of the cable body 1 and is used to vibrate and de-ice when ice forms on the surface of the cable body 1.

[0033] The vibration mechanism includes a fixed ring 2, which is installed on the outside of the cable body 1, and a vibration component is rotatably installed on the outer periphery of the fixed ring 2;

[0034] The heating wire 5 is installed inside the cable body 1 and is used to heat the surface of the cable body 1. The fixing ring 2 is made of thermally conductive material. The cable body 1 consists of cable core 101, load-bearing wire 102, insulation shielding layer 103 and protective sleeve 104. The heating wire 5 is disposed between the insulation shielding layer 103 and the protective sleeve 104.

[0035] When it is necessary to clean the snow from the surface of the cable body 1, turn on the power of the heating wire 5 so that the heating wire 5 can heat the surface of the cable body 1 to melt the snow and prevent the snow from damaging the cable body 1.

[0036] In this embodiment, the vibration component includes a rotating ring 3, which is rotatably mounted on the outer periphery of a fixed ring 2. The rotating ring 3 has a U-shaped cross-section. A roller 10 is rotatably mounted on one inner wall of the rotating ring 3. An eccentric column 11 is eccentrically fixed on the outer surface of the roller 10 away from the rotating ring 3. A rectangular opening 9 is provided through the inner periphery of the rotating ring 3 near the roller 10. The outer periphery of the roller 10 is in contact with the outer surface of the fixed ring 2, and the roller 10 can roll around the outer periphery of the fixed ring 2 as the rotating ring 3 rotates. A power component is also installed inside the rotating ring 3. The power component includes a closed ring 4 fixedly mounted on the outer periphery of the rotating ring 3. Multiple strip-shaped openings 14 are uniformly provided through the outer periphery of the closed ring 4. A blade 8 is slidably mounted on the inner wall of each strip-shaped opening 14. A connecting plate 7 is fixedly mounted on one end of the blade 8 near the fixed ring 2. An annular airbag 6 is fixedly mounted on the inner wall of the rotating ring 3. The connecting plate 7 is fixedly mounted on the outer surface of the annular airbag 6.

[0037] When the heating wire 5 is heated to a certain temperature, the heat will be conducted through the fixed ring 2 to the annular airbag 6 installed inside the rotating ring 3, causing the gas inside the annular airbag 6 to expand due to the heat. This expansion of the annular airbag 6 will push the connecting plate 7 and the blade 8 outward, causing the blade 8 to extend to the outside of the closed ring 4. This allows the rotating ring 3 and the blade 8 to cooperate to form a fan blade structure, so that the rotating ring 3 can be driven to rotate as a whole under the action of external wind. While the rotating ring 3 is rotating, it will drive the roller 10 to roll around the outer circumference of the fixed ring 2. Since the roller 10 is equipped with an eccentric column 11, the roller 10 will vibrate when it rolls, which will cause the rotating ring 3 and the fixed ring 2 to drive the cable body 1 to vibrate, so as to shake off the snow remaining on the surface of the cable body 1 and improve the snow removal effect.

[0038] In this embodiment, two limiting rings 12 are fixedly installed on the outer periphery of the fixed ring 2, and the rotating ring 3 is rotatably installed between the two limiting rings 12, thereby axially limiting the rotating ring 3 through the two limiting rings 12.

[0039] In this embodiment, multiple threaded holes are evenly provided on the outer periphery of the fixing ring 2. Each threaded hole has a locking bolt 13 threadedly connected to its inner wall. After the fixing ring 2 is placed on the cable body 1, the locking bolt 13 is tightened so that the end of the locking bolt 13 abuts against the surface of the cable body 1, so as to achieve the limiting effect of the fixing ring 2.

[0040] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: when it is necessary to clean the snow on the surface of the cable body 1, the power supply of the heating wire 5 is turned on so that the heating wire 5 heats the surface of the cable body 1 in order to melt the snow and prevent the snow from damaging the cable body 1.

[0041] When the heating wire 5 is heated to a certain temperature, the heat will be conducted through the fixed ring 2 to the annular airbag 6 installed in the rotating ring 3, causing the gas in the annular airbag 6 to expand due to the heat. This expansion of the annular airbag 6 will push the connecting plate 7 and the blade 8 outward, causing the blade 8 to extend to the outside of the closed ring 4. This will allow the rotating ring 3 and the blade 8 to cooperate to form a fan blade structure, so that the rotating ring 3 can be driven to rotate as a whole under the action of external wind. While the rotating ring 3 is rotating, it will drive the roller 10 to roll around the outer circumference of the fixed ring 2. Since the roller 10 is equipped with an eccentric column 11, the roller 10 will vibrate when it rolls, which will cause the rotating ring 3 and the fixed ring 2 to drive the cable body 1 to vibrate, so as to shake off the snow remaining on the surface of the cable body 1 and improve the snow removal effect.

[0042] After the snow on the surface of the cable body 1 is cleared, the power supply of the heating wire 5 is turned off to stop heating the surface of the cable body 1. This allows the gas in the annular airbag 6 to cool and contract, thereby causing the contracted annular airbag 6 to drive the blade plate 8 to retract into the rotating ring 3 through the connecting plate 7. This prevents the rotating ring 3 from rotating continuously and causing long-term shaking of the cable body 1, which would affect the stability of the cable body 1 connection.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
