Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power cables, and particularly relates to a cold-resistant and anti-freezing cable structure. BACKGROUND

[0002] The cold-resistant and anti-freezing cable is a special cable specially designed for stable operation in extremely low temperature and cold environment. Its core feature is that it can resist material embrittlement, cracking and performance attenuation caused by low temperature, and ensure the continuity and reliability of power transmission or signal control. The key technology of the cable lies in the special materials used. Usually, excellent low-temperature-resistant elastomers (such as TPU, TPE), silicone rubber or modified polyvinyl chloride (PVC) are used as insulation and sheath materials. These materials can still maintain excellent flexibility and elasticity in extremely cold conditions, avoiding damage due to freezing, bending or external force impact. Some models also add anti-freezing oil paste between the conductors to prevent water vapor from entering and freezing, further improving their anti-freezing ability. It is mainly used in outdoor power supply in cold regions, ice and snow cleaning equipment, frozen and refrigerated warehouses, rail transit in high-cold regions, wind power generation and field exploration, etc. It is a key infrastructure to ensure the normal operation of equipment and life safety in cold environments

[0003] The existing cold-resistant and anti-freezing cable usually uses cross-linked polyethylene material for the outer layer. Its unique three-dimensional network molecular structure greatly improves the heat deformation resistance and mechanical strength of the material. In low temperature environment, this stable network structure can effectively prevent the molecular chain from being "frozen" and losing elasticity, so it can still maintain excellent impact resistance and flexibility in severe cold. However, the cable will shrink in low temperature conditions, and the tightly laid cable will generate a huge shrinkage tension due to cold shrinkage. This force will directly act on the connection points (such as terminal heads and connectors) at both ends of the cable, which may cause the connectors to loosen, the contact to be poor, and even the conductor to be pulled off, causing overheating or power failure.

[0004] Therefore, cross-linked polyethylene is widely used to manufacture the insulation layer of cold-resistant cables, which can ensure that the cable does not crack and become brittle in extremely cold conditions, and maintains stable electrical insulation performance SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a cold-resistant and anti-freezing cable structure.

[0006] The technical scheme adopted to solve the above technical problem is: a cold-resistant and anti-freezing cable structure, comprising a protection mechanism, the outer wall of the protection mechanism is covered with an insulation shielding layer, and the outer wall of the insulation shielding layer is provided with a buffer mechanism.

[0007] The outer wall of the buffer mechanism is provided with an inner lining layer, the outer wall of the inner lining layer is provided with a galvanized steel wire armor, and the outer wall of the galvanized steel wire armor is provided with an anti-freezing mechanism.

[0008] The outer wall of the anti-freezing mechanism is provided with an outer sheath, the protection mechanism is provided with a plurality of filling sleeves, the copper core conductor is arranged in each of the plurality of filling sleeves, the center of the insulation shielding layer is provided with a control assembly, and the anti-freezing mechanism can provide a certain temperature for the outer sheath, so that the anti-freezing mechanism is better resistant to cold.

[0009] Further, the protection mechanism comprises a first protection layer and a second protection layer, a plurality of partition plates are fixedly connected between the first protection layer and the second protection layer, and a triangular plate is arranged in each of the first protection layer, the second protection layer and the plurality of partition plates.

[0010] According to the above technical scheme, since the first protection layer, the second protection layer and the plurality of partition plates are provided with cavities, and a plurality of triangular plates are fixedly connected in the cavities, when the cable is extruded by external pressure, the first protection layer can buffer the external pressure, and the force borne by the first protection layer can be dispersed by the plurality of triangular plates, so that the first protection layer can better resist the external pressure, and the first protection layer, the second protection layer and the plurality of partition plates are designed as hollow structures, so that the weight of the structure is greatly reduced, the overall weight of the cable is reduced, and the cable is convenient to transport and lay.

[0011] Further, the first protection layer, the second protection layer and the plurality of partition plates are provided with cavities, and the plurality of triangular plates are fixedly connected in the corresponding cavities.

[0012] According to the above technical scheme, when the external temperature decreases, the copper core conductor shrinks due to cold, the first protection layer, the second protection layer and the plurality of partition plates have a certain elastic effect, so as to compensate for the space of the shrinking copper core conductor, and effectively protect the cable.

[0013] Further, the insulation shielding layer is wrapped on the outer wall of the first protection layer.

[0014] According to the above technical scheme, the insulation shielding layer can uniformly distribute the electric field, eliminate the air gap, prevent the copper core conductor from being locally discharged, protect the main insulation, and combine with the grounding layer to shield the electric field in the cable, so as to ensure the operation safety and personal safety.

[0015] Further, the buffer mechanism comprises a buffer layer wrapped on the outer wall of the insulation shielding layer, a plurality of limiting grooves are formed in the outer wall of the buffer layer, and a plurality of arc-shaped pieces are fixedly connected to the outer wall of the buffer layer.

[0016] Through the technical scheme, when the external temperature is low, the outer sheath and the inner liner shrink due to the cold, so that the diameter of the inner liner becomes smaller, thereby extruding the plurality of arc-shaped pieces in contact. Since one end of the arc-shaped piece is fixedly connected to the outer wall of the buffer layer and the other end is in sliding connection, when the inner wall of the inner liner shrinks the outer wall of the arc-shaped piece, the arc-shaped piece can support the force, and the greater the force, the slower the one end of the arc-shaped piece slides in the corresponding limiting groove, thereby resisting the pressure. Similarly, when the temperature rises, the diameter of the inner liner returns to the original state, reducing the pressure on the arc-shaped piece, so that the arc-shaped piece slowly returns to the initial state. When the cable is subjected to external pressure, the plurality of arc-shaped pieces can also resist a certain pressure, thereby greatly improving the cold resistance effect of the cable.

[0017] Further, one end of each of the plurality of arc-shaped pieces is fixedly connected to the outer wall of the buffer layer, and the other end of each of the plurality of arc-shaped pieces is in sliding connection in the corresponding limiting groove.

[0019] Further, the outer wall of each of the plurality of arc-shaped pieces is in contact with the inner wall of the inner liner, and the galvanized steel wire armor is wound on the outer wall of the inner liner.

[0020] Through the technical scheme, the inner liner has a buffering effect, can reduce the damage to the cable when subjected to impact, and cooperates with the galvanized steel wire armor to have a moisture-proof and sealing effect, can prevent water, moisture and other chemical corrosive substances from penetrating longitudinally, and at the same time, in a low temperature state, the inner liner still has sufficient flexibility and elasticity, and can provide continuous, uniform and seamless sealing and protection.

[0022] Through the technical scheme, when the outer sheath is subjected to external pressure, the outer sheath first resists the maximum external pressure and simultaneously transmits the pressure to the plurality of arch belts, the plurality of arch belts simultaneously disperse the pressure, the load-carrying capacity is improved, and the damage of the pressure to the cable is greatly reduced; when the outer sheath is damaged, the water-blocking powder is arranged in the plurality of notches, once the water invades from the outer wall of the outer sheath, the water-blocking powder expands when meeting water, thereby blocking the channel of the water molecules to continue to diffuse inward, thereby protecting the cable from erosion, and enabling the cable to normally operate; when the external temperature is low, in order to enable the cable to normally operate, the plurality of heating wires heat and transmit the temperature to the plurality of arch belts, thereby transmitting the temperature to the outer sheath, the cold resistance effect of the outer sheath is greatly improved, the cable is further prevented from being frozen, and the anti-freezing layer also has the anti-freezing effect, and the protection of the copper core conductor is greatly improved.

[0023] Further, the outer sheath is made of cross-linked polyethylene material.

[0025] Further, the control assembly comprises a control insulation layer arranged in the second protective layer, and the control insulation layer is provided with a control conductor.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] like Figures 1-7 As shown, this embodiment of a cold-resistant and freeze-proof cable structure includes a protection mechanism 1. The protection mechanism 1 includes a first protective layer 101 and a second protective layer 102. Multiple partitions 103 are fixedly connected to the first protective layer 101 and the second protective layer 102. Triangular plates 104 are provided within the first protective layer 101, the second protective layer 102, and the multiple partitions 103. Since cavities are provided within the first protective layer 101, the second protective layer 102, and the multiple partitions 103, and multiple triangular plates 104 are fixedly connected within these cavities, when the cable is subjected to external pressure, the first protective layer 101 can buffer the external pressure, and the multiple triangular plates 104 can disperse the force, thereby better resisting external pressure. Furthermore, the first protective layer 101, the second protective layer 102, and the multiple partitions... The 103 structure features a hollow design, significantly reducing the weight of the structure and thus the overall weight of the cable, facilitating its transportation and installation. The first protective layer 101, the second protective layer 102, and multiple partitions 103 all contain cavities. Multiple triangular plates 104 are fixedly connected to their respective cavities. When the external temperature decreases, the copper core conductor 9 contracts due to the cold. The first protective layer 101, the second protective layer 102, and the multiple partitions 103 have a certain elasticity, thus compensating for the contraction of the copper core conductor 9 and effectively protecting the cable. The insulating shielding layer 2 covers the outer wall of the first protective layer 101. The insulating shielding layer 2 can uniformly distribute the electric field, eliminate air gaps, prevent partial discharge on the surface of the copper core conductor 9, protect the main insulation, and, combined with the grounding layer, shield the electric field inside the cable, ensuring operational safety and personal safety.

[0038] like Figures 1-5As shown, the outer wall of the protection mechanism 1 is covered with an insulating shielding layer 2, the outer wall of the insulating shielding layer 2 is provided with a buffer mechanism 3, the buffer mechanism 3 includes a buffer layer 301 covered on the outer wall of the insulating shielding layer 2, a plurality of limiting grooves 302 are arranged on the outer wall of the buffer layer 301, and a plurality of arc-shaped pieces 303 are fixedly connected to the outer wall of the buffer layer 301. When the external temperature is low, at this time, the outer sheath 7 and the inner lining layer 4 are cold-shrunk, so that the diameter of the inner lining layer 4 becomes smaller, thereby extruding the plurality of arc-shaped pieces 303 in contact. Since one end of the arc-shaped piece 303 is fixedly connected to the outer wall of the buffer layer 301, and the other end is in sliding connection, when the inner wall of the inner lining layer 4 is shrunk to the outer wall of the arc-shaped piece 303, the arc-shaped piece 303 can support the force, and the greater the force, the slower the one end of the arc-shaped piece 303 slides in the corresponding limiting groove 302, thereby resisting the pressure. Similarly, when the temperature rises, the diameter of the inner lining layer 4 returns to the original state, reducing the pressure on the arc-shaped piece 303, so that the arc-shaped piece 303 slowly returns to the initial state. When the cable is subjected to external pressure, the plurality of arc-shaped pieces 303 can also resist a certain pressure, thereby greatly improving the cold resistance effect of the cable. One end of the plurality of arc-shaped pieces 303 is fixedly connected to the outer wall of the buffer layer 301, and the other end of the plurality of arc-shaped pieces 303 is slidingly connected in the corresponding limiting groove 302. When the arc-shaped piece 303 is subjected to pressure, the arc-shaped piece 303 deforms, so that the one end thereof slides in the corresponding limiting groove 302, and the arc-shaped piece 303 has a certain elastic effect, so that it can return to the initial state under normal conditions, thereby prolonging the service life. The outer wall of the buffer mechanism 3 is provided with the inner lining layer 4, the outer wall of the inner lining layer 4 is provided with the galvanized steel wire armor 5, the outer wall of the plurality of arc-shaped pieces 303 is in contact with the inner wall of the inner lining layer 4, the galvanized steel wire armor 5 is wound on the outer wall of the inner lining layer 4, the inner lining layer 4 has a buffering effect, can reduce the damage to the cable when subjected to impact, and cooperates with the galvanized steel wire armor 5 to have a moisture-proof and sealing effect, can prevent water, moisture and other chemical corrosive substances from penetrating longitudinally, and at the same time in a low temperature state, the inner lining layer 4 still has sufficient flexibility and elasticity, and can provide continuous, uniform and seamless sealing and protection.

[0039] As Figures 1-6As shown, the outer wall of the galvanized steel wire armor 5 is provided with an anti-freezing mechanism 6, the anti-freezing mechanism 6 includes an anti-freezing layer 601 wrapped on the outer wall of the galvanized steel wire armor 5, the outer wall of the anti-freezing layer 601 is fixedly connected with a plurality of annularly distributed arch bands 602, a plurality of notches 603 are arranged between the plurality of arch bands 602, and a plurality of heating wires 604 are arranged in the plurality of arch bands 602. When the outer sheath 7 is subjected to external pressure, the outer sheath 7 first resists the maximum external pressure, and at the same time transmits the pressure to the plurality of arch bands 602, the plurality of arch bands 602 simultaneously disperses the pressure, improves the carrying capacity, and greatly reduces the damage to the cable caused by the pressure. When the outer sheath 7 is damaged, a water-blocking powder is arranged in each of the plurality of notches 603. Once the water from the outer wall of the outer sheath 7 invades, the material will swell when encountering water, thereby blocking the channel for the water molecules to continue to diffuse inward, thereby protecting the cable from erosion and enabling the cable to operate normally. When the external temperature is low, in order to enable the cable to operate normally, the plurality of heating wires 604 heat and transmit the temperature to the plurality of arch bands 602, thereby transmitting the temperature to the outer sheath 7, greatly improving the cold resistance effect of the outer sheath 7, further preventing the cable from freezing, and the anti-freezing layer 601 also has an anti-freezing effect, greatly improving the protection of the copper core conductor 9.

[0040] As shown in Figures 1-6 The outer wall of the anti-freezing mechanism 6 is provided with an outer sheath 7, the outer sheath 7 is made of cross-linked polyethylene material, has very high cold resistance and heat insulation effect, prevents the temperature of the outside world from being too low to affect the inner layer material, and at the same time has wear resistance and impact resistance effect, can withstand the impact pressure brought by the outside world in the first time, and protects the inner layer material in the largest range, thereby ensuring that the cable can still maintain flexibility, no cracking and normal work in a cold environment.

[0041] As shown in Figures 1-7 The protection mechanism 1 is provided with a plurality of filling sleeves 8, the plurality of filling sleeves 8 are provided with copper core conductors 9, the center of the insulating shielding layer 2 is provided with a control assembly 10, the anti-freezing mechanism 6 can provide a certain temperature for the outer sheath 7, thereby better resisting cold, the control assembly 10 includes a control insulating layer 1001 arranged in the second protective layer 102, and the control insulating layer 1001 is provided with a control conductor 1002. When the outer wall of the outer sheath 7 is damaged, the control conductor 1002 can quickly locate the damage point, which is helpful for workers to quickly repair it, the control insulating layer 1001 is immune to external electromagnetic interference, reduces interference to surrounding equipment, greatly reduces electromagnetic interference, and ensures stable transmission of signals.

[0043] When the external temperature is low, the outer sheath 7 and the inner liner 4 are cold contracted at this time, so that the diameter of the inner liner 4 is reduced, thereby extruding the plurality of arc-shaped sheets 303 in contact, since one end of the arc-shaped sheet 303 is fixedly connected with the outer wall of the buffer layer 301, and the other end is in sliding connection, when the inner wall of the inner liner 4 is contracted to the outer wall of the arc-shaped sheet 303, the arc-shaped sheet 303 can support the force, the greater the force, the slower the one end of the arc-shaped sheet 303 slides in the corresponding limiting groove 302 at this time, thereby resisting the pressure, and the diameter of the inner liner 4 returns to the original state when the temperature rises, the pressure on the arc-shaped sheet 303 is reduced, and the arc-shaped sheet 303 slowly returns to the initial state, when the cable is subjected to external pressure, the plurality of arc-shaped sheets 303 can also resist a certain pressure, thereby greatly improving the cold resistance effect of the cable;

[0044] When the cable is extruded by external pressure, the first protective layer 101 can buffer the external pressure at this time, and the plurality of triangular plates 104 can disperse the force borne, so as to better resist the external pressure, and the first protective layer 101, the second protective layer 102 and the plurality of partition plates 103 are designed as hollow, thereby greatly reducing the weight of the structure, reducing the overall weight of the cable, and facilitating transportation and laying of the cable;
