Description

Technical Field

[0001] The utility model relates to the field of electric wires, in particular to an electric wire with high-temperature resistance function. Background Art

[0002] An electric wire refers to a conductor for transmitting electric energy, which is a material used for power, electrical and related transmission purposes. Electric wires can be divided into three types: bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer and are mainly used for outdoor overhead lines, indoor busbars and switch cabinets. Electromagnetic wires are insulated wires that generate a magnetic field after being energized or induce an electric current in a magnetic field, and are mainly used for motor and transformer windings and other related electromagnetic equipment. Insulated wires have a thin insulation layer and good electrical and mechanical properties, as well as properties such as heat resistance, moisture resistance and solvent resistance.

[0003] Most of the existing electric wires are directly placed on the ground, and the contact area between the electric wire and the ground is large. Continuous shaking and friction may generate high temperature. In a high-temperature environment, the electric wire may heat up rapidly, even causing a fire, because the insulation layer of the electric wire may soften, melt or burn at high temperature, resulting in the exposure of the electric wire, thus increasing the risks of short circuit and electric shock. In addition, under high-temperature conditions, the resistance of the electric wire may increase and the conductivity may decrease, thus affecting the circuit performance, which may lead to a reduction in power transmission efficiency and even affect the normal operation of equipment.

[0004] Therefore, in view of the problem that most of the existing electric wires are directly placed on the ground, the contact area between the electric wire and the ground is large, continuous shaking and friction may generate high temperature, the electric wire may heat up rapidly, thus increasing the risks of short circuit and electric shock, and in addition, the resistance of the electric wire may increase and the conductivity may decrease, thus affecting the circuit performance, an electric wire with high-temperature resistance function can be designed, and a support and protection structure is sleeved inside and outside the electric wire to improve the performance of the electric wire. Content of the Utility Model

[0005] In order to overcome the problems that most of the existing electric wires are directly placed on the ground, the contact area between the electric wire and the ground is large, continuous shaking and friction may generate high temperature, the electric wire may heat up rapidly, thus increasing the risks of short circuit and electric shock, and in addition, the resistance of the electric wire may increase and the conductivity may decrease, thus affecting the circuit performance.

[0006] The technical solution of the present utility model is as follows: A wire with high-temperature resistance function, including a wire heat-resistant outer shell, an installation ring, and a limiting component; multiple groups of installation rings for fixing and placing the wire heat-resistant outer shell on the ground are horizontally sleeved outside the wire heat-resistant outer shell. A limiting component for adjusting according to the thickness of the wire heat-resistant outer shell and limiting and fixing it is provided in the middle of the installation ring. An insulating protection ring sleeve is provided in the middle inside the wire heat-resistant outer shell. The limiting component includes an arc-shaped telescopic sleeve, a circular telescopic column, a circular telescopic sleeve, an arc-shaped telescopic plate, a positioning pin, a positioning hole, and an arc-shaped rubber pad. Four groups of arc-shaped telescopic sleeves are arranged in a ring. An arc-shaped telescopic plate is sleeved and connected between every two groups of arc-shaped telescopic sleeves. A positioning pin is provided at the connection between the arc-shaped telescopic plate and the arc-shaped telescopic sleeve.

[0007] Preferably, first, the limiting component is sleeved outside the wire heat-resistant outer shell. Then, the limiting component is telescopically adjusted according to the thickness of the wire heat-resistant outer shell to limit and fix the wire heat-resistant outer shell, avoiding situations such as the wire heat-resistant outer shell shaking due to external influences. Then, the U-shaped mounting bracket drives the installation ring to be fixedly connected to the ground, thereby fixing and placing the wire heat-resistant outer shell, reducing the contact area between the wire heat-resistant outer shell and the ground, reducing friction and avoiding the generation of high temperature. At the same time, through the protection of the insulating protection ring sleeve and the support column, the wire can work stably for a long time without performance degradation or damage. In addition, reducing the generation of high temperature can reduce the resistance of the wire, maintain the conductivity, improve the power transmission efficiency, and ensure the normal operation of the equipment.

[0008] Preferably, a hole limiting tube is sleeved inside the insulating protection ring sleeve. Four groups of conductors are installed around the inside of the hole limiting tube. During the use of the wire, the hole limiting tube can place the conductors separately to avoid friction and damage between the conductors, affecting their service life. Then, the insulating protection ring sleeve can provide electrical insulation, making it not easy for the wire to generate leakage during use. At the same time, the wire heat-resistant outer shell can work stably for a long time in a high-temperature environment without the wire experiencing performance degradation or damage.

[0009] Preferably, multiple groups of fixed inner rings are horizontally sleeved outside the insulating protection ring sleeve. A fixed outer ring that fits and connects with the wire heat-resistant outer shell is sleeved outside the fixed inner ring. Multiple groups of support columns are installed around between the fixed inner ring and the fixed outer ring. The support columns stably support the fixed inner ring and the fixed outer ring, leaving a space between the wire heat-resistant outer shell and the insulating protection ring sleeve, which helps to optimize the heat conduction path of the wire, enable the wire to dissipate heat more effectively in a high-temperature environment, reduce the internal temperature of the wire, thereby extending the service life of the wire. At the same time, it can enhance the overall strength of the wire, making it maintain a stable shape in a high-temperature environment and not easily deform or collapse.

[0010] Preferably, a U-shaped mounting bracket is installed outside the mounting ring. Two groups of mounting holes for bolts to pass through are horizontally opened at the bottom of the U-shaped mounting bracket. Four groups of fixing holes are circumferentially opened on the mounting ring. After the wire is limited, according to the ground conditions suitable for laying the wire, pass the bolts through the mounting holes to fixedly connect the U-shaped mounting bracket to the ground, thereby reducing the contact area between the wire and the ground.

[0011] Preferably, an arc-shaped rubber pad for increasing friction is installed inside the arc-shaped telescopic sleeve. The arc-shaped rubber pad can increase friction and prevent the wire from shaking during use.

[0012] Preferably, a plurality of positioning holes for positioning pins to pass through are longitudinally opened on the arc-shaped telescopic plate. A circular telescopic column is installed on one side of the outside of the arc-shaped telescopic sleeve. The mounting ring is sleeved outside the heat-resistant outer shell of the wire. Then, according to the thickness of the heat-resistant outer shell of the wire, by adjusting the positioning pins, push the arc-shaped telescopic sleeve to make the arc-shaped telescopic plate contract and adjust along the arc-shaped telescopic sleeve, thereby driving the arc-shaped rubber pad to continuously approach and fit the heat-resistant outer shell of the wire to limit and fix it. After confirmation, pass the positioning pins through the arc-shaped telescopic sleeve and connect them to the arc-shaped telescopic plate through the positioning holes for positioning.

[0013] Preferably, a circular telescopic sleeve is sleeved outside the circular telescopic column. A spring is provided at the connection between the circular telescopic column and the circular telescopic sleeve. A spring rubber damper is provided inside the spring. The circular telescopic sleeve is fixedly connected to the mounting ring through the fixing holes. During the process of limit fixation, the circular telescopic column moves along the circular telescopic sleeve. After adjustment, the elastic force of the spring is used to maintain the stability of the telescopic sleeve and the telescopic column, and firmly support the arc-shaped telescopic sleeve.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. First, the limiting component is sleeved outside the heat-resistant outer shell of the wire. Then, the limiting component is telescopically adjusted according to the thickness of the heat-resistant outer shell of the wire to limit and fix the heat-resistant outer shell of the wire, preventing the heat-resistant outer shell of the wire from shaking due to external influences. Then, the U-shaped mounting bracket drives the mounting ring to be fixedly connected to the ground, thereby fixedly placing the heat-resistant outer shell of the wire, reducing the contact area between the heat-resistant outer shell of the wire and the ground, reducing friction and avoiding the generation of high temperature. At the same time, through the protection of the insulating protection ring sleeve and the support column, the wire can work stably for a long time without performance degradation or damage. In addition, reducing the generation of high temperature can reduce the resistance of the wire, maintain the electrical conductivity, improve the power transmission efficiency, and ensure the normal operation of the equipment;

[0016] 2. The support columns firmly support and fix the inner fixed ring and the outer fixed ring, leaving a space between the heat-resistant outer shell of the wire and the insulating protection ring sleeve, which helps to optimize the heat conduction path of the wire, enables the wire to dissipate heat more effectively in a high-temperature environment, reduces the internal temperature of the wire, thereby extending the service life of the wire. At the same time, it can enhance the overall strength of the wire, keep its stable shape in a high-temperature environment, and is not prone to deformation or collapse.

[0017] 3. Set the installation ring sleeve outside the heat-resistant outer shell of the wire. Then, according to the thickness of the heat-resistant outer shell of the wire, through the adjustment of the positioning pin, push the arc-shaped telescopic sleeve, so that the arc-shaped telescopic plate contracts and adjusts along the arc-shaped telescopic sleeve, thereby driving the arc-shaped rubber pad to continuously approach and fit the heat-resistant outer shell of the wire to limit and fix it. After confirmation, pass the positioning pin through the arc-shaped telescopic sleeve and connect it with the arc-shaped telescopic plate through the positioning hole.

[0025] Please refer to Figure 2 , in this embodiment, a hole limiting tube 102 is sleeved inside the insulating protection ring sleeve 103. Four groups of conductors 101 are installed around the inside of the hole limiting tube 102. During the use of the wire, the hole limiting tube 102 can place the conductors 101 separately, avoiding friction and damage between the conductors 101 and affecting their service life. Then the insulating protection ring sleeve 103 can provide electrical insulation, making it not easy for the wire to generate electric leakage during use. At the same time, the wire heat-resistant outer casing 1 can work stably for a long time in a high-temperature environment without the wire showing performance degradation or damage. Multiple groups of fixed inner rings 104 are horizontally sleeved outside the insulating protection ring sleeve 103. A fixed outer ring 106 that fits and connects with the wire heat-resistant outer casing 1 is sleeved outside the fixed inner ring 104. Multiple groups of support columns 105 are installed around between the fixed inner ring 104 and the fixed outer ring 106.

At the same time, it can enhance the overall strength of the wire, making it maintain a stable shape in a high-temperature environment and not easily deform or collapse.

[0026] Please refer to Figure 3 , in this embodiment, a U-shaped mounting frame 201 is installed outside the installation ring 2. Two mounting holes 202 for bolts to pass through are horizontally opened at the bottom of the U-shaped mounting frame 201. Four groups of fixing holes 203 are opened in a circle on the installation ring 2. After the wire is limited, according to the ground condition suitable for placing the wire, pass the bolts through the mounting holes 202 to make the U-shaped mounting frame 201 fixedly connected to the ground, thereby reducing the contact area between the wire and the ground.

[0027] Please refer to Figure 4 Figure 4 , in this embodiment, an arc-shaped rubber pad 307 for increasing friction is installed inside the arc-shaped telescopic sleeve 301. The arc-shaped rubber pad 307 can increase friction and prevent the wire from shaking during use. A plurality of positioning holes 306 for the positioning pins 305 to pass through are longitudinally provided on the arc-shaped telescopic plate 304. A circular telescopic column 302 is installed on one side of the outside of the arc-shaped telescopic sleeve 301. The mounting ring 2 is sleeved on the outside of the wire heat-resistant housing 1. Then, according to the thickness of the wire heat-resistant housing 1, by adjusting the positioning pins 305, the arc-shaped telescopic sleeve 301 is pushed, so that the arc-shaped telescopic plate 304 contracts and adjusts along the arc-shaped telescopic sleeve 301, thereby driving the arc-shaped rubber pad 307 to continuously approach and fit the wire heat-resistant housing 1 for limiting and fixing it. After confirmation, the positioning pins 305 are passed through the arc-shaped telescopic sleeve 301 and are positioned and connected to the arc-shaped telescopic plate 304 through the positioning holes 306. A circular telescopic sleeve 303 is sleeved on the outside of the circular telescopic column 302. A spring is provided at the connection between the circular telescopic column 302 and the circular telescopic sleeve 303. A spring rubber damper is provided inside the spring. The circular telescopic sleeve 303 is fixedly connected to the mounting ring 2 through the fixing holes 203. During the limiting and fixing process, the circular telescopic column 302 moves along the circular telescopic sleeve 303. After adjustment, the elastic force of the spring is used to maintain the stability of the telescopic sleeve and the telescopic column, and the arc-shaped telescopic sleeve 301 is firmly supported.

[0028] When working, the mounting ring 2 is sleeved on the outside of the wire heat-resistant housing 1. Then, according to the thickness of the wire heat-resistant housing 1, by adjusting the positioning pins 305, the arc-shaped telescopic sleeve 301 is pushed, so that the arc-shaped telescopic plate 304 contracts and adjusts along the arc-shaped telescopic sleeve 301, thereby driving the arc-shaped rubber pad 307 to continuously approach and fit the wire heat-resistant housing 1 for limiting and fixing it. After confirmation, the positioning pins 305 are passed through the arc-shaped telescopic sleeve 301 and are positioned and connected to the arc-shaped telescopic plate 304 through the positioning holes 306. During the limiting and fixing process, the circular telescopic column 302 moves along the circular telescopic sleeve 303. After adjustment, the elastic force of the spring is used to maintain the stability of the telescopic sleeve and the telescopic column, and the arc-shaped telescopic sleeve 301 is firmly supported. In addition, the arc-shaped rubber pad 307 can increase friction and prevent the wire from shaking during use;

[0029] After the wire is limited, according to the ground condition suitable for laying the wire, the bolt is passed through the mounting hole 202 so that the U-shaped mounting frame 201 is fixedly connected to the ground, thereby reducing the contact area between the wire and the ground;

[0030] During the use of the wire, the hole limiting tube 102 can place the conductor 101 separately, preventing friction and damage between the conductors 101 and affecting their service life. Then, the insulation protection ring sleeve 103 can provide electrical insulation, making it difficult for the wire to leak electricity during use. At the same time, the heat-resistant outer shell 1 of the wire can work stably for a long time in a high-temperature environment without the wire experiencing performance degradation or damage. Then, the support column 105 firmly supports and fixes the inner fixing ring 104 and the outer fixing ring 106, leaving a space between the heat-resistant outer shell 1 of the wire and the insulation protection ring sleeve 103, which helps to optimize the heat conduction path of the wire and enables the wire to dissipate heat more effectively in a high-temperature environment.

[0031] Through the above steps, first, the limiting component is sleeved outside the heat-resistant outer shell 1 of the wire. Then, the limiting component is adjusted in length according to the thickness of the heat-resistant outer shell 1 of the wire to limit and fix the heat-resistant outer shell 1 of the wire, preventing the heat-resistant outer shell 1 of the wire from shaking due to external influences. Then, the U-shaped mounting bracket 201 drives the mounting ring 2 to be fixedly connected to the ground, thereby fixing and placing the heat-resistant outer shell 1 of the wire, reducing the contact area between the heat-resistant outer shell 1 of the wire and the ground, reducing friction and avoiding the generation of high temperature. At the same time, protected by the insulation protection ring sleeve 103 and the support column 105, the wire can work stably for a long time without performance degradation or damage. In addition, reducing the generation of high temperature can reduce the resistance of the wire, maintain its conductivity, improve the power transmission efficiency, and ensure the normal operation of the equipment, so as to solve the problem that most existing wires are directly placed on the ground, with a large contact area between the wire and the ground. Continuous shaking and friction may generate high temperature, and the wire may quickly heat up, increasing the risks of short circuit and electric shock. In addition, the resistance of the wire may increase, and its conductivity may decrease, thus affecting the circuit performance.
