[0009] Preferably, the balancing mechanism includes a connecting block, with a first U-shaped frame fixedly connected to both the top and bottom of the connecting block. A first rotating frame is rotatably connected to the inner wall of the first U-shaped frame. A balancing spring is fixedly connected to the end of the first rotating frame away from the first U-shaped frame. A sliding sleeve is fixedly connected to the portion of the first rotating frame located inside the balancing spring. A buffer rod is slidably connected to the inner wall of the sliding sleeve.

The end of the second rotating frame near the buffer rod is fixedly connected to the balancing spring, and the end of the second rotating frame away from the buffer rod rotates. A second U-shaped frame is connected, and a mounting plate is fixedly connected to the side of the second U-shaped frame away from the second rotating frame. The connecting block is fixedly connected to the side of the fixed plate. Two sets of connecting blocks are provided and symmetrically distributed on the fixed plates at both ends of the cable body. When the cable expands at high temperature, the tension increases and is distributed to the first U-shaped frames on both sides through the connecting blocks. The first rotating frame rotates, the balance spring is compressed, and the sliding sleeve slides along the buffer rod to absorb the expansion tension and maintain the stability of the mounting plate. When the cable contracts at low temperature, the pre-tightening force increases and is transmitted to the balancing mechanism. The first rotating frame rotates in the opposite direction, the balance spring recovers its deformation, and the sliding sleeve slides in the opposite direction to relieve the contraction pre-tightening force and prevent the cable from breaking.

[0010] Preferably, the cooling assembly includes a coolant storage tank, with a water outlet filter plate fixedly connected through and to the bottom of the coolant storage tank. Multiple sets of water outlet filter plates are evenly distributed at the bottom of the coolant storage tank. A water-blocking ring is fixedly connected to one side of the water outlet filter plate inside the coolant storage tank.

A trigger clamping plate is fixedly connected to the end of the connecting rod away from the opening and closing sealing plate. The coolant storage tank is fixedly connected to one side of the first fixed clamping plate. When the cable expands at high temperature, it squeezes the trigger clamping plate, which pushes the opening and closing sealing plate to slide along the water-blocking ring and compress the fourth spring through the connecting rod. The outlet filter plate is then released from its seal, and the coolant in the coolant storage tank drips onto the surface of the cable through the outlet filter plate to cool it down. After the cable temperature decreases, it returns to its initial diameter, and the fourth spring resets, pushing the opening and closing sealing plate to reseal the outlet filter plate and stop the coolant from flowing out.

[0011] This invention provides an overhead cable with adaptive thermal expansion and contraction characteristics. It has the following beneficial effects: 1. This overhead cable with adaptive thermal expansion and contraction characteristics achieves precise initial fixation of cables of different diameters through the staggered wrapping of the first and second fixing plates and the multi-position adaptable design of the mounting posts. The first and second fixing plates adopt a wrapping structure to fit the curved surface of the cable, improving the wrapping degree of the cable and enhancing the stability of the initial fixation. The mounting posts can be inserted into the mounting slots of different first mounting blocks to adapt to cables of different diameters, improving the adaptability of the equipment. After the mounting posts are inserted, they can be quickly locked without the need for tools. The fixing operation can be completed by a single person, improving installation efficiency, avoiding the offset error of manual positioning, and laying the foundation for subsequent precise clamping.

[0012] 2. This overhead cable features adaptive thermal expansion and contraction characteristics. An arc-shaped clamping plate driven by an adjusting screw, in conjunction with a third spring, forms an elastic clamping system. The elastic force of the third spring drives the arc-shaped clamping plate to tightly adhere to the cable surface and adapts to the diameter changes caused by thermal expansion and contraction. At high temperatures, the cable expands, and the third spring compresses to absorb the expansion stress, preventing damage to the cable sheath caused by traditional rigid clamping. At low temperatures, the cable contracts, and the third spring resets, pushing the clamping plate to follow suit, maintaining stable clamping and preventing cable loosening and displacement. The force is evenly distributed, avoiding damage to the internal core wires caused by excessive local pressure. Furthermore, the built-in electric heating wire in the arc-shaped clamping plate provides constant temperature protection for the cable in low-temperature or rainy / snowy environments, preventing the cable from becoming brittle and its sheath from cracking due to low temperatures.

[0013] 3. This overhead cable with adaptive thermal expansion and contraction characteristics, through the coordinated design of multiple rotating frames, balance springs, and buffer rods, precisely addresses the tension changes caused by the thermal expansion and contraction of the cable. In high-temperature environments, cable expansion leads to increased tension and sag. The connecting block distributes the tension to the first U-shaped frames on both sides. The rotation of the first and second rotating frames, combined with the compression of the balance springs, and the sliding sleeve sliding along the buffer rods, can absorb additional tension, preventing the cable from being pulled apart due to excessive tension or the fixing device from loosening. At the same time, it keeps the mounting plate stable and prevents the overall device from shifting. In low-temperature environments, cable contraction leads to a sudden increase in pre-tightening force. The balance springs reverse and reset, and the elastic restoring force relieves the contraction pre-tightening force, preventing the cable from stretching the core wire, reducing transmission performance, or even breaking due to excessive contraction. This improves the operational safety of the cable in different temperature environments.

[0014] 4. This overhead cable with adaptive thermal expansion and contraction characteristics adopts an automated design of cable expansion triggering and spring reset sealing to achieve intelligent constant temperature protection for the cable. Under high temperature conditions, the cable expansion and compression triggers the clamping plate, which pushes the opening and closing sealing plate to slide through the connecting rod, opening the water outlet filter plate. Coolant automatically drips onto the cable surface to cool it down, preventing damage to the cable due to continuous high temperature and extending the cable's service life. When the cable temperature drops to a safe range, the cable shrinks back to its initial diameter. The fourth spring drives the opening and closing sealing plate to reset and seal the water outlet filter plate, stopping the coolant flow and preventing coolant waste. Moreover, no manual intervention is required for start-up and shutdown, achieving adaptive regulation of cable temperature and further improving the device's cable protection performance and practicality.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] For the first embodiment, please refer to... Figures 1-6This invention provides a technical solution: an overhead cable with adaptive thermal expansion and contraction characteristics, comprising a cable body 1, with fixed plates 2 fixedly connected to both ends of the cable body 1. A first rotating shaft 3 and a second rotating shaft 4 are rotatably connected to the top and bottom of the fixed plates 2 respectively via bearings. A first fixed clamping plate 5 is fixedly connected to the first rotating shaft 3, and adjacent sets of first fixed clamping plates 5 are rotatably connected by rotating pins. A second fixed clamping plate 6 is fixedly connected to the second rotating shaft 4, and adjacent sets of second fixed clamping plates 6 are rotatably connected by rotating pins. A balancing mechanism 7 is fixedly connected to one side of the fixed plates 2, and a cooling component 8 is fixedly connected to one side of the first fixed clamping plate 5. Adjusting screws 9 are threaded through and threaded to the tops of both the first and second fixed clamping plates 5 and 6. Multiple sets of adjusting screws 9 are evenly distributed on the first and second fixed clamping plates 5 and 6. An adaptive clamping mechanism 10 is fixedly connected to the inner walls of both the first and second fixed clamping plates 5 and 6. One end of the adjusting screw 9 passes through the adaptive clamping mechanism 10 and is slidably connected to it. A first mounting block 11 is evenly fixedly connected to the fixed clamping plate 5, and a mounting mechanism 12 is fixedly connected to the second fixed clamping plate 6. A mounting groove 111 is formed on one side of the first mounting block 11, and a U-shaped limiting opening 112 is formed on the top of the first mounting block 11, communicating with the mounting groove 111. A first spring 113 is fixedly connected to the inner wall of the mounting groove 111. The mounting mechanism 12 includes a second mounting block 121, and a mounting post 122 is slidably connected through one side of the second mounting block 121. One end of the mounting post 122 is fixedly connected to... There is an adjustment knob 123, and a placement groove 124 is opened on the top of the mounting column 122. A second spring 125 is fixedly connected to the bottom of the inner wall of the placement groove 124. A limit rod 126 is fixedly connected to the end of the second spring 125 away from the bottom of the inner wall of the placement groove 124. The side of the limit rod 126 is slidably connected to the inner wall of the placement groove 124. A second mounting block 121 is fixedly connected to the second fixing clamp 6. The side of the mounting column 122 is slidably connected to the inner wall of the mounting groove 111. The side of the limit rod 126 is slidably connected to the inner wall of the U-shaped limit port 112.

[0019] In use, when installing the cable body 1, the first fixing plate 5 and the second fixing plate 6 are first fixed in a staggered, encircling manner around the cable body 1. Depending on the different diameters of the cable body 1, the mounting post 122 of the mounting mechanism 12 is inserted into the mounting slots 111 of different first mounting blocks 11. During the insertion of the mounting post 122 into the mounting slot 111, the limiting rod 126 is first pressed, causing the limiting rod 126 to compress the second spring 125 and retract into the placement slot 124. Then, the mounting post 122 is inserted into the mounting slot 111. When the limiting rod 126 moves to the position of the U-shaped limiting port 112, the second spring 125 resets and pushes the limiting rod 126 out, and the limiting rod 126 is engaged in the U-shaped limiting port 112, thereby fixing the mounting post 122 in the mounting slot 111. This achieves the initial fixation of the cable body 1 by the first fixing plate 5 and the second fixing plate 6, thus adapting to cable bodies 1 of different diameters and improving the adaptability of the device.

[0020] For the second embodiment, please refer to... Figures 1-7 Based on the first embodiment, the present invention provides a technical solution: the adaptive clamping mechanism 10 includes a fixed sleeve 101, a sliding adjustment plate 102 is slidably connected to the inner wall of the fixed sleeve 101, a third spring 103 is fixedly connected to one side of the sliding adjustment plate 102, a sliding column 104 is fixedly connected to the end of the third spring 103 away from the sliding adjustment plate 102, an arc-shaped clamping plate 105 is fixedly connected to the end of the sliding column 104 away from the third spring 103, an electric heating wire is installed inside the arc-shaped clamping plate 105, the fixed sleeve 101 is provided with multiple sets and evenly fixedly connected to the inner walls of the first fixed clamping plate 5 and the second fixed clamping plate 6, the top of the fixed sleeve 101 passes through and is slidably connected to the adjusting screw 9, and the side of the sliding adjustment plate 102 away from the third spring 103 is fixedly connected to the end of the adjusting screw 9 located inside the fixed sleeve 101.

[0021] In use, after initial positioning, rotating the adjusting screw 9 causes it to slide within the fixed sleeve 101 of the adaptive clamping mechanism 10, pushing the sliding adjusting plate 102 to move. The sliding adjusting plate 102 compresses or stretches the third spring 103. The elastic force of the third spring 103 acts on the sliding column 104, thereby moving the arc-shaped clamping plate 105, causing it to tightly adhere to the surface of the cable body 1. When the cable body 1 expands due to high temperature, its diameter increases. Therefore, under the action of the third spring 103, the arc-shaped clamping plate 105 will still tightly adhere to the cable body 1 as it expands, allowing the sliding... The adjusting plate 102 simultaneously compresses the third spring 103. The elastic deformation of the third spring 103 can absorb the stress generated by the expansion of the cable body 1, preventing the cable body 1 from being damaged due to excessive compression. When the cable body 1 shrinks due to low temperature, its diameter decreases, and the third spring 103 recovers its deformation, pushing the sliding adjusting plate 102 and the arc-shaped clamping plate 105 to move inward, so that the arc-shaped clamping plate 105 always fits tightly against the surface of the cable body 1, ensuring the stability of the clamping. In addition, the electric heating wire installed inside the arc-shaped clamping plate 105 can work in low-temperature environments, providing a certain amount of heat to the cable body 1, and preventing low temperature or rain and snow from affecting the operation of the cable body 1.

[0022] Third embodiment, please refer to Figures 1-8 Based on the second embodiment, the present invention provides a technical solution: the balancing mechanism 7 includes a connecting block 71, a first U-shaped frame 72 is fixedly connected to the top and bottom of the connecting block 71, a first rotating frame 73 is rotatably connected to the inner wall of the first U-shaped frame 72, a balancing spring 74 is fixedly connected to the end of the first rotating frame 73 away from the first U-shaped frame 72, a sliding sleeve 75 is fixedly connected to the part of the first rotating frame 73 located inside the balancing spring 74, a buffer rod 76 is slidably connected to the inner wall of the sliding sleeve 75, the buffer rod 76 is located inside the balancing spring 74, a second rotating frame 77 is fixedly connected to the end of the buffer rod 76 away from the sliding sleeve 75, a second rotating frame 77 is fixedly connected to the end of the second rotating frame 77 near the buffer rod 76 and a second U-shaped frame 78 is rotatably connected to the end of the second rotating frame 77 away from the buffer rod 76, a mounting plate 79 is fixedly connected to the side of the second U-shaped frame 78 away from the second rotating frame 77, the connecting block 71 is fixedly connected to the side of the fixing plate 2, and two sets of connecting blocks 71 are provided and symmetrically distributed on the fixing plates 2 at both ends of the cable body 1.

[0023] During use, when the cable body 1 expands due to high temperature, the tension and sag of the cable body 1 increase, affecting its normal use and safety. At this time, the tension generated by the cable body 1 is transmitted to the balancing mechanism 7. The connecting block 71 of the balancing mechanism 7 distributes this tension to the first U-shaped frame 72 on both sides. The first rotating frame 73 rotates within the first U-shaped frame 72, simultaneously compressing the balancing spring 74. The sliding sleeve 75 slides on the buffer rod 76, which provides stable support and further buffering within the balancing spring 74. The second rotating frame 77 rotates within the second U-shaped frame 78. Through this series of structures, the elastic deformation of the balancing spring 74 absorbs the increased tension of the cable body 1 due to high-temperature expansion, keeping the mounting plate 79 in a relatively stable position. This reduces the impact of cable body 1 tension changes on the overall device, ensuring that the cable body 1 can still function normally under high-temperature expansion conditions, improving the stability and safety of the device. When the cable body 1 contracts due to low temperature, the preload of the cable body 1 increases. To prevent the cable body 1 from breaking, the cable body 1 generates… The preload is transmitted to the balancing mechanism 7. The connecting block 71 distributes this contraction force to the first U-shaped frame 72 on both sides. The first rotating frame 73 rotates in the opposite direction within the first U-shaped frame 72. At this time, the balancing spring 74 begins to recover its deformation. The sliding sleeve 75 slides in the opposite direction on the buffer rod 76. The buffer rod 76 still plays a stable support and buffering role inside the balancing spring 74. The second rotating frame 77 rotates in the opposite direction within the second U-shaped frame 78. The elastic restoring force of the balancing spring 74 can alleviate the increased preload force of the cable body 1 due to low temperature contraction, so that the mounting plate 79 still maintains a relatively stable position, preventing the cable body 1 from being pulled apart due to excessive contraction. This further ensures that the cable body 1 can work normally under low temperature contraction conditions, further improving the stability and safety of the device. It also enables the device to adaptively adjust to the thermal expansion and contraction of the cable body 1, improving the flexibility of the device.

[0024] For the fourth embodiment, please refer to [link / reference]. Figures 1-10Based on the third embodiment, the present invention provides a technical solution: the cooling component 8 includes a coolant storage tank 81, a water outlet filter plate 82 is fixedly connected through and fixed to the bottom of the coolant storage tank 81, multiple sets of water outlet filter plates 82 are evenly distributed at the bottom of the coolant storage tank 81, a water blocking ring 83 is fixedly connected to one side of the water outlet filter plate 82 inside the coolant storage tank 81, an opening and closing sealing plate 84 is slidably connected to the inner wall of the water blocking ring 83, a fourth spring 85 is fixedly connected to the side of the opening and closing sealing plate 84 away from the water outlet filter plate 82, one end of the fourth spring 85 away from the opening and closing sealing plate 84 is fixedly connected to the inner wall of the coolant storage tank 81, a connecting rod 86 is fixedly connected to the side of the opening and closing sealing plate 84 near the water outlet filter plate 82, the connecting rod 86 passes through the water outlet filter plate 82 and is slidably connected to the water outlet filter plate 82, a trigger clamping plate 87 is fixedly connected to the end of the connecting rod 86 away from the opening and closing sealing plate 84, and the coolant storage tank 81 is fixedly connected to one side of the first fixed clamping plate 5.

[0025] During use, when the cable body 1 expands due to heat in a high-temperature environment, to prevent damage caused by the continuous high temperature of the cable body 1, the expansion of the cable body 1 will compress the trigger clamping plate 87 of the cooling component 8. The trigger clamping plate 87 pushes the opening and closing sealing plate 84 to slide within the water-blocking ring 83 through the connecting rod 86, while compressing the fourth spring 85. After the opening and closing sealing plate 84 moves, the water outlet filter plate 82 is no longer completely sealed, and the coolant in the coolant storage tank 81 of the cooling component 8 will flow out through the water outlet filter plate 82. After the coolant flows out, it will drip onto the surface of the high-temperature cable body 1, which may damage the cable body. The cable body 1 is cooled down. As the coolant continues to flow out, the temperature of the cable body 1 gradually decreases. When the temperature of the cable body 1 drops to a certain level, the cable body 1 returns to its initial diameter, the fourth spring 85 returns to its deformation, and pushes the opening and closing sealing plate 84 to move in the opposite direction, resealing the water outlet filter plate 82 and preventing the coolant from continuing to flow out. In this way, the cooling component 8 can automatically control the flow and stop of the coolant according to the temperature of the cable body 1, realize intelligent cooling of the cable body 1, avoid damage to the cable body 1 due to continuous high temperature, and further improve the protection performance and practicality of the device for the cable body 1.

[0026] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
