Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage cables, and specifically to a voltage-stabilized and corrosion-resistant low-voltage cable. Background Art

[0002] A cable is a conductor covered with an insulating layer, a protective layer, a shielding layer, etc. for transmitting electric power or signal current and signal voltage. It can be divided into high-voltage cables and low-voltage cables according to voltage. Compared with low-voltage overhead lines and low-voltage overhead insulated lines, although the cost of low-voltage cable lines is higher and laying and maintenance are more difficult, due to its characteristics such as reliable operation, no utility poles, no occupation of the ground, no visual obstruction, and less influence from the outside world, it is widely used in low-voltage distribution systems. When laying low-voltage cables, it is easy for workers to step on the low-voltage cables. When being extruded, the conductor will be flattened or even broken, resulting in the interruption of the signal transmission of the low-voltage cable and the inability to effectively transmit electric power or signal current and signal voltage, affecting normal use. For this reason, a Chinese patent discloses a low-voltage cable with compressive resistance and anti-fracture, with the application number 202222160550.2. This patent can support the shielding layer and the wear-resistant layer through the setting of a support assembly, a wrapping body, and contact strips. And the five contact strips can evenly support the shielding layer and the wear-resistant layer. At the same time, the arc-shaped support strips can also support and connect the wrapping body and the shielding layer. The support strength of the five-pointed-star wrapping body and the arc-shaped support strips is high and evenly distributed, which can improve the internal support strength of the low-voltage cable. When being stepped on, the wrapping body, contact strips, and support strips can resist and protect the cable conductor, insulating layer, and outer sheath, thereby improving the compressive resistance and anti-fracture performance of the low-voltage cable and solving the problem of fracture after being stressed;

[0003] However, the cable skin in this patent lacks an anti-corrosion protection structure. When the cable is exposed to the external environment for a long time, it is easily affected by foreign objects with corrosion effects in the external environment, resulting in the corrosion of the cable surface and shortening the service life of the cable.

[0014] According to the above technical solution, a convenient heat preservation mechanism is installed inside the outer protective layer;

[0015] The convenient heat preservation mechanism includes an installation cylinder;

[0016] An installation cylinder is installed in the middle of the inner side of the outer protective layer. A heating wire is embedded in the middle of the installation cylinder. Heat conduction wires are equidistantly installed on the surface of the heating wire along the circumferential direction. A protective sleeve is sleeved on the surface of the heat conduction wire.

The arc-shaped rubber positioning block closely adheres to the surface of the shielding layer. The radian of the arc-shaped rubber positioning block is greater than 180 degrees.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use:

[0021] 1. An anti-corrosion protection mechanism is provided. The surface of the outer protective layer is wrapped and protected by an anti-corrosion protective layer, thereby playing an anti-corrosion role and preventing the cable from being corroded by external acid-base foreign objects during use, which may cause the cable to malfunction. The connecting column and the rubber block are embedded inside the card slot, and the reinforcing strip is covered and fixed on the surfaces of the left splicing strip and the right splicing strip to fix both ends of the anti-corrosion protective layer. This makes the fixing method of the anti-corrosion protective layer simple and provides great convenience for subsequent peeling and replacement. By replacing the anti-corrosion protective layer, the anti-corrosion ability of the cable surface can be improved and maintained, thereby extending the service life of the cable.

[0022] The left splicing strip and the right splicing strip are closely attached to the surface of the outer protective layer through the adhesive strip to fix both ends of the anti-corrosion protective layer, making the anti-corrosion protective layer closely fixed and playing a positioning role. There is no need to continuously hold the anti-corrosion protective layer by hand, making it not easy to fall off, which provides great convenience for subsequent pressing and installing the reinforcing strip. At the same time, the sealing strip improves the sealing between the reinforcing strip and both ends of the anti-corrosion protective layer, preventing external liquid from penetrating inward.

[0023] 2. The odor block in the storage block has a certain odor and insect repellent effect. The odor emits outward from the ventilation holes, playing an insect repellent and protective role around the cable, preventing insects in the cable installation and use environment from biting the cable and damaging its epidermis. At the same time, the arc-shaped wear-resistant strips are distributed on both sides of the arc-shaped fitting strip to protect the arc-shaped fitting strip and the storage block. The arc-shaped wear-resistant strips and the wear-resistant convex grains protrude, playing a wear-resistant and protective role to prevent the storage block from being worn.

[0024] 3. A convenient heat preservation mechanism is provided. The heating wire emits heat outward, playing a role in heating and insulating the inside of the cable. In cold weather, it increases the temperature inside the cable itself, enabling the core to be used normally at an appropriate temperature. At the same time, the triangular heat preservation metal block and the arc-shaped heat preservation metal block are mutually attached and spliced to form three circles to surround the three cores. The heat emitted by the heating wire can be transmitted to the triangular heat preservation metal block and the arc-shaped heat preservation metal block through the heat conducting wire, thereby wrapping and insulating the core, improving the heat preservation effect, and playing a role in isolating the external cold environment to prevent the transmission efficiency of the core from decreasing due to too low temperature, resulting in excessive consumption of resources.

[0025] At the same time, the connecting strip will transfer the heat on the triangular heat preservation metal block outward to the metal cylinder, forming another layer of heat preservation layer, improving the heat preservation and heating ability inside the cable. Moreover, the metal cylinder has more uniform heat preservation and heat dissipation, and is closer to the surface of the cable, also playing a certain role in heating and insulating the surface of the cable. When it snows, snowflakes will not adhere to the surface of the cable. The continuously emitted heat will heat the falling snowflakes, causing them to melt and slide off, preventing the continuous accumulation of snowflakes from causing a certain pressure on the cable suspension and resulting in cable breakage.

[0026] 4. The core body is positioned by the arc-shaped rubber positioning block, so that the core bodies are evenly distributed outside the heating wire. The arc-shaped rubber positioning block is clamped on the surface of the shielding layer, playing a role of limiting and fixing the core body, preventing the core body from falling off. The arc-shaped rubber positioning block has a certain deformation ability, deforming and clinging tightly when the core body is clamped, and providing a certain limiting ability subsequently, which provides great convenience for the subsequent installation of the mechanism. The buffer layer provides a certain buffer protection for the space outside the core body and plays a certain supporting role for the triangular heat-insulating metal block, preventing the triangular heat-insulating metal block from being squeezed and deformed.

[0027] In summary, by combining the anti-corrosion protection mechanism and the convenient heat-insulating mechanism, the cable is protected in terms of anti-corrosion, wear resistance, heat-insulating isolation, etc., improving the structural strength of the cable itself, making the cable more suitable for the environment, reducing the damage of external environmental factors to the cable, and extending the service life of the cable.

The surfaces of the shielding layers 3 are all wrapped and installed with inner protective layers 4. An outer protective layer 5 is installed outside the inner protective layer 4. Both the inner protective layer 4 and the outer protective layer 5 are plastic rubber. After extrusion, the cable structure is wrapped and shaped. A filling layer 6 is filled inside the outer protective layer 5. The filling layer 6 is a polyethylene filler, which has a certain waterproof and moisture-proof effect. An anti-corrosion protection mechanism 7 is installed on the surface of the outer protective layer 5;

[0044] The anti-corrosion protection mechanism 7 includes an anti-corrosion protective layer 701, a notch 702, a left splicing strip 703, a right splicing strip 704, a bonding rubber strip 705, a card slot 706, a reinforcing long strip 707, a connecting column 708, a rubber clamping block 709, a sealing strip 710, an arc-shaped fitting strip 711, a storage block 712, an odor block 713, a ventilation hole 714, an arc-shaped wear-resistant strip 715 and wear-resistant convex particles 716;

[0045] The surface of the outer protective layer 5 is wrapped and installed with an anti-corrosion protective layer 701. The anti-corrosion protective layer 701 is made of anti-corrosion rubber and has anti-corrosion properties. There is a notch 702 between the two ends of the anti-corrosion protective layer 701. One end of the anti-corrosion protective layer 701 is fixedly connected to a left splicing strip 703, and the other end of the anti-corrosion protective layer 701 is fixedly connected to a right splicing strip 704. Both the left splicing strip 703 and the right splicing strip 704 are located inside the notch 702, and the edges of the left splicing strip 703 and the right splicing strip 704 are in contact with each other. The bottom ends of both the left splicing strip 703 and the right splicing strip 704 are fixedly connected with adhesive strips 705. The left splicing strip 703 and the right splicing strip 704 are fixedly adhered to the surface of the outer protective layer 5 through the adhesive strips 705. The width of the reinforcement strip 707 is the same as the sum of the widths of the left splicing strip 703 and the right splicing strip 704. The tops of the left splicing strip 703 and the right splicing strip 704 are evenly provided with card slots 706. The surface of the left splicing strip 703 and the right splicing strip 704 is covered and installed with a reinforcement strip 707. The reinforcement strip 707 covers the top of the notch 702. The surface of the reinforcement strip 707 is flush with the outer wall of the anti-corrosion protective layer 701. The two ends at the bottom of the reinforcement strip 707 are evenly and fixedly installed with connecting columns 708. The bottom ends of the connecting columns 708 are fixedly connected with rubber blocks 709. The two side parts of the reinforcement strip 707 are symmetrically adhered with sealing strips 710. The connecting columns 708 are inserted into the inside of the card slots 706, and the rubber blocks 709 are movably clamped at the bottom of the card slots 706. The diameter of the rubber blocks 709 is larger than the diameter of the card slots 706. The two sealing strips 710 are respectively in contact with the two ends of the anti-corrosion protective layer 701. The surface of the outer protective layer 5 is wrapped and protected by the anti-corrosion protective layer 701, thereby playing an anti-corrosion role and preventing the cable from being corroded by external acid-base foreign matters during use, resulting in the cable being unable to be used normally. Moreover, the connecting columns 708 and the rubber blocks 709 are embedded into the inside of the card slots 706, covering and fixing the reinforcement strip 707 on the surface of the left splicing strip 703 and the right splicing strip 704, fixing the two ends of the anti-corrosion protective layer 701, making the fixing method of the anti-corrosion protective layer 701 simple and providing great convenience for subsequent peeling and replacement. By replacing the anti-corrosion protective layer 701, the anti-corrosion ability of the cable surface is improved and maintained, thereby extending the service life of the cable;

[0046] The left splicing strip 703 and the right splicing strip 704 are closely attached to the surface of the outer protective layer 5 through the adhesive strips 705, fixing the two ends of the anti-corrosion protective layer 701, making the anti-corrosion protective layer 701 closely fixed, playing a positioning role, eliminating the need to continuously hold the anti-corrosion protective layer 701 by hand, making it not easy to fall off, and providing great convenience for subsequent pressing and installing the reinforcement strip 707. At the same time, the sealing strips 710 improve the sealing performance between the reinforcement strip 707 and the two ends of the anti-corrosion protective layer 701, preventing external liquid from penetrating inward;

[0047] Arc-shaped fitting strips 711 are fixedly installed at equal intervals on the surface of the anti-corrosion protective layer 701. Storage blocks 712 are installed at equal intervals on the surface of the arc-shaped fitting strips 711. Odor blocks 713 are embedded inside the storage blocks 712. Vent holes 714 are arranged at equal intervals on the surface of the storage blocks 712. Arc-shaped wear-resistant strips 715 are installed on both sides of the arc-shaped fitting strips 711 on the surface of the anti-corrosion protective layer 701. Wear-resistant convex grains 716 are installed at equal intervals on the surface of the arc-shaped wear-resistant strips 715. The odor blocks 713 are insect-repellent odor agents. The thickness of the arc-shaped wear-resistant strips 715 is greater than the sum of the thicknesses of the arc-shaped fitting strips 711 and the storage blocks 712. The odor blocks 713 in the storage blocks 712 have a certain odor insect-repellent effect, and the odor is emitted outward from the vent holes 714, which plays an insect-repellent protection role around the cable, preventing insects from biting the cable in the cable installation and use environment and causing damage to its epidermis. At the same time, the arc-shaped wear-resistant strips 715 are distributed on both sides of the arc-shaped fitting strips 711 to protect the arc-shaped fitting strips 711 and the storage blocks 712. The arc-shaped wear-resistant strips 715 and the wear-resistant convex grains 716 protrude, playing a wear-resistant protection role to prevent the storage blocks 712 from being worn and causing the odor blocks 713 to fall off;

[0048] A convenient heat preservation mechanism 8 is installed inside the outer protective layer 5;

[0049] The convenient heat preservation mechanism 8 includes an installation cylinder 801, a heating wire 802, a heat conduction wire 803, a protective sleeve 804, an arc-shaped heat preservation metal block 805, a triangular heat preservation metal block 806, a connecting strip 807, a metal cylinder 808, a fixing block 809, an arc-shaped rubber positioning block 810 and a buffer layer 811;

[0050] In the middle of the inner side of the outer protective layer 5, an installation cylinder 801 is installed. In the middle of the installation cylinder 801, a heating wire 802 is embedded. Along the circumferential direction of the surface of the heating wire 802, heat conduction wires 803 are installed at equal intervals. A protective sleeve 804 is sleeved on the surface of the heat conduction wire 803. Three cores 1 are distributed at equal intervals outside the installation cylinder 801 and the heating wire 802. The heat conduction wire 803 penetrates through the wall of the installation cylinder 801. The protective sleeve 804 is connected to the surface of the installation cylinder 801. Arc-shaped heat preservation metal blocks 805 are installed at equal intervals at a position on one side of the heat conduction wire 803 on the surface of the installation cylinder 801. Triangular heat preservation metal blocks 806 are installed outside the inner protective layer 4. The arc-shaped heat preservation metal blocks 805 and the heating wire 802 are staggered. Both ends of the arc-shaped heat preservation metal block 805 are connected to the inner wall of the triangular heat preservation metal block 806. The corners of the arc-shaped heat preservation metal block 805 and the triangular heat preservation metal block 806 are spliced into a circle to surround the core 1. The end of the heat conduction wire 803 is connected to the inner wall of the triangular heat preservation metal block 806. Connection strips 807 are fixedly connected to the three corners on the surface of the triangular heat preservation metal block 806. A metal cylinder 808 is closely attached to the inner wall of the outer protective layer 5. Fixing blocks 809 are installed in the middle of the inner wall of the arc-shaped heat preservation metal block 805. The end of the fixing block 809 is fixedly connected with an arc-shaped rubber positioning block 810. The inner wall of the metal cylinder 808 is connected to the connection strip 807. The arc-shaped rubber positioning block 810 is closely attached to the surface of the shielding layer 3. The radian of the arc-shaped rubber positioning block 810 is greater than 180 degrees. A buffer layer 811 is filled inside the triangular heat preservation metal block 806. The buffer layer 811 is a polypropylene filler, which has good elasticity and plays a role in relieving pressure. The heating wire 802 emits heat outward, playing a role in heating and heat preservation inside the cable. In cold weather, the temperature inside the cable itself is increased, so that the core 1 can be used normally at a suitable temperature. At the same time, the triangular heat preservation metal block 806 and the arc-shaped heat preservation metal block 805 are mutually attached and spliced to form three circles to surround the three cores 1. The heat released by the heating wire 802 can be transmitted to the triangular heat preservation metal block 806 and the arc-shaped heat preservation metal block 805 through the heat conduction wire 803, and then the core 1 is wrapped for heat preservation, improving the heat preservation effect and playing a role in isolating the external cold environment, preventing the transmission efficiency of the core 1 from being reduced due to too low temperature and causing excessive consumption of resources;

[0051] At the same time, the connection strip 807 will transfer the heat on the triangular heat preservation metal block 806 outward to the metal cylinder 808 to form another heat preservation layer, improving the heat preservation and heating ability inside the cable. Moreover, the metal cylinder 808 has more uniform heat preservation and heat dissipation, is closer to the surface skin of the cable, and also plays a certain role in heating and heat preservation on the surface layer of the cable, so that snowflakes will not adhere to the surface of the cable during snowfall weather. The continuous heat dissipation will heat the falling snowflakes and make them dissolve and slide off, preventing the continuous accumulation of snowflakes from causing a certain pressure on the cable suspension and resulting in cable breakage;

[0052] The core body 1 is positioned by the arc-shaped rubber positioning block 810, so that the core bodies 1 are equidistantly distributed outside the heating wire 802. The arc-shaped rubber positioning block 810 is clamped on the surface of the shielding layer 3, which plays a role in limiting and fixing the core body 1, preventing the core body 1 from falling off. The arc-shaped rubber positioning block 810 has a certain deformation ability. When the core body 1 is clamped, it deforms and closely adheres, providing a certain limiting ability subsequently, which provides great convenience for the subsequent installation of the mechanism. The buffer layer 811 provides a certain buffer protection for the space outside the core body 1 and plays a certain supporting role for the triangular heat-insulating metal block 806, preventing the triangular heat-insulating metal block 806 from being squeezed and deformed.

[0053] The working principle and usage process of the present invention are as follows: First, during cable production, the insulating layer 2 and the shielding layer 3 are sequentially sleeved and wrapped on the surface of the core body 1. The three core bodies 1 are equidistantly distributed in a circular pattern outside the installation cylinder 801, and the core body 1 is embedded in the middle of the arc-shaped rubber positioning block 810. The radian of the arc-shaped rubber positioning block 810 is greater than 180 degrees. When the core body 1 is embedded, it undergoes a certain deformation and then closely adheres to the surface of the shielding layer 3. The arc-shaped rubber positioning block 810 plays a role in wrapping and positioning the core body 1, preventing it from falling off easily. Subsequently, the inner protective layer 4, the triangular heat-insulating metal block 806, and the arc-shaped heat-insulating metal block 805 can all be installed in sequence without causing the core body 1 to fall and skew. The buffer layer 811 is filled in the gap inside the triangular heat-insulating metal block 806, and the metal cylinder 808 is fixed on the outside of the triangular heat-insulating metal block 806 through the connecting strip 807. The outer protective layer 5 is extrusion-wrapped on the surface of the metal cylinder 808, and the filling layer 6 is filled in the gap generated between the inside of the metal cylinder 808 and the triangular heat-insulating metal block 806;

[0054] The anti-corrosion protective layer 701 is wrapped outside the outer protective layer 5. The left splicing strip 703 and the right splicing strip 704 are mutually attached, and the adhesive strip 705 is closely attached to the surface of the outer protective layer 5, playing a role in bonding and fixing the entire anti-corrosion protective layer 701, preventing the anti-corrosion protective layer 701 from falling off. Subsequently, when the anti-corrosion protective layer 701 is kept fixed, the reinforcing strip 707 can be taken and inserted into the notch 702. The reinforcing strip 707 covers the surfaces of the left splicing strip 703 and the right splicing strip 704, and the connecting column 708 and the rubber clamping block 709 are both inserted into the card slot 706. The rubber clamping block 709 is soft and can deform. When inserted into the card slot 706 with a smaller diameter, it undergoes a certain deformation, and then the rubber clamping block 709 is more firmly clamped and installed. The reinforcing strip 707 plays a role in splicing and fixing the left splicing strip 703 and the right splicing strip 704, improving the connectivity between the two, and further enabling the anti-corrosion protective layer 701 to be more firmly wrapped on the surface of the outer protective layer 5 and not fall off easily;

[0055] During the installation and use of the cable, both the arc-shaped wear-resistant strip 715 and the wear-resistant convex particles 716 play a role in wear protection, so that the anti-corrosion protection layer 701 and the storage block 712 will not be worn. When the cable is in the long-term use environment, the anti-corrosion protection layer 701 plays an anti-corrosion protection role, and external corrosive substances are isolated by the anti-corrosion protection layer 701 to prevent them from penetrating inward and causing damage to the cable. Moreover, the sealing strip 710 is closely attached to the anti-corrosion protection layer 701, improving its sealing performance and preventing liquid from penetrating inward. At the same time, the odor block 713 inside the storage block 712 will emit a certain smell, which penetrates outward through the ventilation holes 714, playing a role in repelling insects around the cable and preventing pests from approaching and biting the cable to cause damage;

[0056] After the anti-corrosion protection layer 701 is used for a long time, there will be a certain amount of wear, and it needs to be replaced regularly and in a timely manner. The staff pulls the reinforcement strip 707 outward, extracts the rubber clamping block 709 and the connecting column 708 from the card slot 706, and the reinforcement strip 707 is removed, that is, the limit fixation of the left splicing strip 703 and the right splicing strip 704 is released. Then, the adhesive strip 705 is torn off, and the anti-corrosion protection layer 701 is peeled off from the surface of the outer protection layer 5. Take a new anti-corrosion protection layer 701, wrap it around the surface of the outer protection layer 5 again, and use the reinforcement strip 707 for limit fixation;

[0057] If the cable is used in snowy and cold weather, the heating wire 802 is energized to emit heat outward. The heat is transferred outward from the heat-conducting wire 803 to the triangular heat-insulating metal block 806 and the arc-shaped heat-insulating metal block 805. The circular area formed by the triangular heat-insulating metal block 806 and the arc-shaped heat-insulating metal block 805 surrounds the core 1. Furthermore, the heat also surrounds the core 1, playing a role in heat preservation and protection for the core 1. At the same time, part of the heat is transferred to the metal cylinder 808 through the connecting strip 807, forming another heat-insulating layer, improving the heat-insulating effect inside the cable, isolating the external cold weather, reducing the influence of low temperature on the normal transmission process of the core 1, and enabling the core 1 to always operate at an appropriate temperature. The metal cylinder 808 is close to the outer surface of the cable and will dissipate heat outward, playing a role in heat preservation and protection for the surface of the cable. When snow falls and adheres to the surface of the cable, the dissipated heat will heat and melt the snow, causing it to dissolve and slide off, preventing snowflakes from continuously adhering and accumulating on the cable, resulting in excessive pressure and breakage.
