Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a carbon fiber reinforced low-temperature resistant and tensile-resistant power cable. Background Technology

[0002] Carbon fiber reinforced low-temperature tensile cable is a high-performance special cable that uses carbon fiber as its reinforcement. By incorporating high-strength carbon fiber elements into the cable structure, it significantly improves mechanical tensile strength and low-temperature resistance, maintaining flexibility and structural stability in extremely cold environments. This cable also possesses excellent conductivity and fatigue resistance, capable of withstanding frequent bending and significant tensile forces without easily being damaged. It is primarily used for power transmission and signal control in extreme environments, such as Arctic and Antarctic scientific expeditions, new energy equipment in high-altitude and cold regions, ice and snow sports facilities, and aerospace, providing reliable connection protection for equipment operation under harsh low-temperature conditions.

[0003] Existing cables have significant deficiencies in terms of connection protection and tensile strength. Their connections are typically wrapped with simple insulating tape or heat-shrink tubing, lacking an effective mechanical clamping mechanism. This makes them prone to loosening due to vibration or temperature changes, leading to increased contact resistance or even short circuits. Conventional cable tensile strength designs rely heavily on external clamps or bundling, which cannot provide uniform buffering and self-adaptive locking under stress. Under external pulling, joints are prone to detachment or cable damage. Furthermore, most existing structures do not achieve multi-directional synchronous locking, resulting in limited protection range and complex operation. They also cannot maintain the flexibility and locking force of materials in low-temperature environments, affecting the long-term reliability of the cable.

[0004] In view of this, we propose a carbon fiber reinforced low-temperature resistant and tensile-resistant power cable. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: A carbon fiber reinforced low-temperature resistant and tensile-resistant power cable includes a carbon fiber reinforced protective sleeve, inside which a cable is installed, and inside the cable a copper core wire is installed. There are two sets of carbon fiber reinforced protective sleeves, symmetrically arranged. It also includes a wiring protection structure for protecting the connection point after the copper core wire in the cable is connected; and an anti-detachment structure to prevent the cable from falling off due to external pulling after connection. The wiring protection structure includes a fixing plate, positioned between the symmetrical carbon fiber reinforced protective sleeves. Turntables are rotatably connected to both sides of the fixing plate, and a linkage rod is fixedly connected to the side of each turntable away from the fixing plate. A protective plate is fixedly connected inside the fixing plate, and wiring protection holes are opened on both sides of the protective plate. A push rod is inserted and slidably connected to the inner side of each wiring protection hole, and an arc-shaped rubber block is fixedly connected to the end of the push rod near the center of the wiring protection hole.

[0006] Preferably, the wiring protection structure further includes external threaded posts, the number of which is two sets, and the two sets of external threaded posts are respectively fixedly connected to both sides of the fixed disk, and the surface of the external threaded posts is provided with four sets of movable grooves.

[0007] Preferably, a connecting rod is fixedly connected to the inner side of the turntable, and a large gear is fixedly connected to the end of the connecting rod away from the turntable, and the connecting rod passes through the movable groove.

[0008] Preferably, there are seven sets of wiring protection holes, and the seven sets of wiring protection holes are arranged in a circumferential array with the center line of the protective disk as the axis. Each set of wiring protection holes is rotatably connected to a rotating ring, and a small gear is fixedly connected to the surface of the rotating ring. There are also seven sets of small gears, and the seven sets of small gears mesh with each other. At the same time, the six sets of small gears on the outer side mesh with the large gear.

[0009] Preferably, the rotating ring has a paving groove on the side of its surface away from the pinion, and a lever is fixedly connected through the inside of the push rod.

[0010] Preferably, the lever passes through the protective disc and is slidably connected to the protective disc, and both ends of the lever are inserted into the actuation groove opened on the surface of the rotating ring.

[0011] Preferably, there are six sets of push rods, and the six sets of push rods are arranged in a circular array with the center line of the wiring protection hole as the axis. At the same time, there are six sets of push rods in each set of wiring protection holes.

[0012] Preferably, the anti-detachment structure includes a rubber sleeve, which is fitted over the carbon fiber reinforced protective sleeve, and a mounting buckle is fixedly connected to the surface of the rubber sleeve. A connecting plate is fixedly connected to the end of the rubber sleeve away from the mounting buckle. A locking rod is slidably connected to the inner side of the connecting plate. A locking block is fixedly connected to the end of the locking rod near the carbon fiber reinforced protective sleeve, and a slider is fixedly connected to the surface of the locking rod.

[0013] Preferably, the connecting plate is rotatably connected to the inside of the connecting plate. The rotating plate has an arc-shaped groove on the side near the slider. A crossbar is fixedly connected to the surface of the rotating plate. An internal threaded sleeve is fixedly connected to the end of the crossbar away from the rotating plate. A telescopic rod is inserted into and slidably connected to the inner side of the end of the internal threaded sleeve away from the crossbar. A linkage ring is fixedly connected to the end of the telescopic rod away from the internal threaded sleeve.

[0014] Preferably, the surface of the linkage ring is provided with a circular hole, and the surface of the telescopic rod is fitted with a spring. One end of the spring is fixedly connected to the surface of the linkage ring, and the other end is fixedly connected to the surface of the internal threaded sleeve.

[0015] By employing the above technical solution, the present invention provides a carbon fiber reinforced low-temperature resistant and tensile-resistant power cable. It possesses at least the following beneficial effects: 1. This invention uses a rotating turntable to drive a connecting rod to rotate, causing the connecting rod fixedly connected to the inside of the turntable to rotate as well. This causes the large gear fixed to the other end of the connecting rod to rotate. The large gear meshes with the small gears in the seven sets of wiring protection holes on the protective disc. The small gears are fixed to the surface of the rotating ring. When the rotating ring rotates, the actuating groove on its surface drives the lever inserted therein to move. The lever is fixedly connected inside the push rod, which is inserted into the wiring protection hole and slidably connected. One end of the push rod is fixed with an arc-shaped rubber block. When the rotating ring rotates, through the linkage of the actuating groove and the lever, the push rod slides towards the center of the wiring protection hole, pushing the arc-shaped rubber block to tightly press against the connection point of the copper core wire, forming uniform circumferential pressure to ensure a stable and insulated connection, preventing loosening or short circuits.

[0016] 2. This invention uses externally threaded posts to fix the device to both sides of the fixed disk. The movable grooves on its surface allow the connecting rod to pass through and move, ensuring the stability of rotational transmission. The seven sets of wiring protection holes on the protective disk are arranged in a circumferential array, and the six sets of push rods within each set of holes are also arranged in a circumferential array. Through the meshing of small gears and the driving of large gears, multi-directional synchronous clamping is achieved, enhancing the protective effect.

[0017] 3. In this invention, when the rotating plate is rotated, the arc-shaped groove drives the slider to move, causing the locking rod and locking block to slide towards the carbon fiber reinforced protective sleeve, thus achieving locking. A crossbar is fixed to the surface of the rotating plate, and the crossbar is connected to an internal threaded sleeve. A telescopic rod is inserted into the internal threaded sleeve, and a linkage ring is fixed to one end of the telescopic rod. The circular hole on the surface of the linkage ring is used for position adjustment. A spring is sleeved on the surface of the telescopic rod, with one end fixed to the linkage ring and the other end fixed to the internal threaded sleeve, providing elastic buffering. When the cable is pulled by an external force, the spring compresses to absorb energy, preventing sudden detachment. At the same time, the sliding of the linkage ring and the telescopic rod maintains a stable locking force. Overall, the wiring protection structure ensures the safety and reliability of the electrical connection, while the anti-detachment structure provides mechanical tensile protection. The two work together to enable the cable to operate efficiently in low-temperature and tensile environments. Attached Figure Description

[0020] 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.

[0021] A carbon fiber reinforced low-temperature resistant and tensile-resistant power cable, such as Figure 1 - Figure 10 As shown, the device includes a carbon fiber reinforced protective sleeve 1, inside which a cable 4 is installed, and inside the cable 4 a copper core wire 5 is installed. There are two sets of carbon fiber reinforced protective sleeves 1, and the two sets of carbon fiber reinforced protective sleeves 1 are symmetrically arranged. It also includes a wiring protection structure 2, which is used to protect the connection point after the copper core wire 5 in the cable 4 is connected. It also includes an anti-detachment structure 3, which is used to prevent the cable 4 from being pulled off by external force after connection. The wiring protection structure 2 includes a fixing plate 21, which is set between the symmetrical carbon fiber reinforced protective sleeves 1. Turntables 22 are rotatably connected to both sides of the fixing plate 21, and a linkage rod 23 is fixedly connected to the side of the two sets of turntables 22 away from the fixing plate 21. A protective plate 28 is fixedly connected inside the fixing plate 21. Wiring protection holes 215 are opened on both sides of the protective plate 28, and a push rod 29 is inserted and slidably connected to the inside of the wiring protection hole 215. An arc-shaped rubber block 211 is fixedly connected to the end of the push rod 29 near the center of the wiring protection hole 215. The wiring protection structure 2 also includes two sets of external threaded posts 24, which are fixedly connected to both sides of the fixed disk 21. Four sets of movable grooves 25 are formed on the surface of each external threaded post 24. A connecting rod 26 is fixedly connected to the inner side of the turntable 22. A large gear 27 is fixedly connected to the end of the connecting rod 26 away from the turntable 22, and the connecting rod 26 passes through the movable groove 25. Seven sets of wiring protection holes 215 are arranged in a circumferential array around the center line of the protective disk 28. A rotating ring 212 is rotatably connected to each set of wiring protection holes 215. Seven sets of small gears 214 are fixedly connected to the surface of the rotating ring 212, and these seven sets mesh with each other. Simultaneously, the six outer sets of small gears 214 mesh with the large gear 27.

[0022] When protection of the wiring points is required, two sets of carbon fiber reinforced protective sleeves 1 are first symmetrically arranged on both sides of the fixed plate 21. Rotating the turntable 22 drives the connecting rod 23 to rotate, causing the connecting rod 26 fixedly connected to the inside of the turntable 22 to rotate accordingly. The large gear 27 fixed to the other end of the connecting rod 26 thus rotates. The large gear 27 meshes with the small gear 214 inside the seven sets of wiring protection holes 215 on the protective plate 28. The small gear 214 is fixed to the surface of the rotating ring 212. When the rotating ring 212 rotates, the actuating groove 213 on its surface drives the lever 210 inserted therein to move. The lever 210 is fixedly connected inside the push rod 29, which is inserted into the wiring protection hole 215 and slidably connected. One end of the push rod 29 is fixed with an arc-shaped rubber block 211. When the rotating ring 212 rotates, the push rod 29 slides toward the center of the wiring protection hole 215 through the linkage of the toggle groove 213 and the lever 210, pushing the arc-shaped rubber block 211 to press tightly against the wiring point of the copper core wire 5, forming a uniform circumferential pressure to ensure that the wiring is stable and insulated, preventing loosening or short circuit.

[0023] A toggle groove 213 is provided on the surface of the rotating ring 212 away from the pinion 214. A lever 210 is fixedly connected through the inside of the push rod 29. The lever 210 passes through the protective disc 28 and is slidably connected to the protective disc 28. Both ends of the lever 210 are inserted into the toggle groove 213 on the surface of the rotating ring 212. There are six sets of push rods 29. The six sets of push rods 29 are arranged in a circumferential array with the center line of the wiring protection hole 215 as the axis. At the same time, there are six sets of push rods 29 in each set of wiring protection holes 215.

[0024] The external threaded post 24 is fixed to both sides of the fixed plate 21, and its surface movable groove 25 allows the connecting rod 26 to pass through and move, ensuring the stability of rotational transmission. The seven sets of wiring protection holes 215 of the protective plate 28 are arranged in a circumferential array, and the six sets of push rods 29 in each set of holes are also arranged in a circumferential array. Through the meshing of the small gears 214 and the drive of the large gears 27, multi-directional synchronous clamping is achieved, enhancing the protection effect. The anti-detachment structure 3 is used to prevent the cable 4 after wiring from being pulled off by external force. The rubber sleeve 31 is fitted on the outside of the carbon fiber reinforced protective sleeve 1 and fixed in position by the mounting buckle 32.

[0025] The anti-detachment structure 3 includes a rubber sleeve 31, which is fitted over the carbon fiber reinforced protective sleeve 1. A mounting buckle 32 is fixedly connected to the surface of the rubber sleeve 31. A connecting plate 33 is fixedly connected to the end of the rubber sleeve 31 away from the mounting buckle 32. A locking rod 34 is slidably connected to the inner side of the connecting plate 33. A locking block 35 is fixedly connected to the end of the locking rod 34 near the carbon fiber reinforced protective sleeve 1. A slider 36 is fixedly connected to the surface of the locking rod 34. A rotating plate 37 is rotatably connected inside the connecting plate 33. An arc-shaped groove 38 is formed on the side of the rotating plate 37 near the slider 36. A crossbar 39 is fixedly connected to the surface of the rotating plate 37. An internal threaded sleeve 310 is fixedly connected to the end of the crossbar 39 away from the rotating plate 37. A telescopic rod 311 is inserted into and slidably connected to the inner side of the end of the internal threaded sleeve 310 away from the crossbar 39. A linkage ring 312 is fixedly connected to the end of the telescopic rod 311 away from the internal threaded sleeve 310. A circular hole 313 is provided on the surface of the linkage ring 312, and a spring 314 is fitted on the surface of the telescopic rod 311. One end of the spring 314 is fixedly connected to the surface of the linkage ring 312, and the other end is fixedly connected to the surface of the internal threaded sleeve 310.

[0026] The anti-detachment structure 3 is used to prevent the cable 4 from being pulled off by external force after wiring. The rubber sleeve 31 is fitted over the carbon fiber reinforced protective sleeve 1 and fixed in position by the mounting buckle 32. The locking rod 34 is slidably connected to the inside of the connecting plate 33. One end of the locking rod 34 is fixed with a locking block 35 for clamping the carbon fiber reinforced protective sleeve 1. The slider 36 on the surface of the locking rod 34 cooperates with the arc groove 38 on one side of the rotating plate 37. When the rotating plate 37 is rotated, the arc groove 38 drives the slider 36 to move, causing the locking rod 34 and the locking block 35 to slide towards the carbon fiber reinforced protective sleeve 1, thereby achieving locking.

[0027] When using the carbon fiber reinforced low-temperature resistant and tensile-resistant power cable of the present invention, if protection of the wiring points is required, firstly, two sets of carbon fiber reinforced protective sleeves 1 are symmetrically arranged on both sides of the fixed disk 21. Rotating the turntable 22 drives the connecting rod 23 to rotate, and the connecting rod 26 fixedly connected to the inner side of the turntable 22 rotates accordingly. The large gear 27 fixed to the other end of the connecting rod 26 thus rotates. The large gear 27 meshes with the small gears 214 in the seven sets of wiring protection holes 215 opened on the protective disk 28. The small gears 214 are fixed to the surface of the rotating ring 212. When the rotating ring 212 rotates, the actuating groove 213 opened on its surface drives the actuating rod 210 inserted therein to move. The actuating rod 210 is fixedly connected to the inside of the push rod 29. The push rod 29 is inserted into the wiring protection hole 215 and slidably connected. One end of the push rod 29 is fixed with an arc-shaped rubber block 211. When the rotating ring 212 rotates, the push rod 29 slides towards the center of the wiring protection hole 215 through the linkage of the toggle groove 213 and the lever 210, pushing the arc-shaped rubber block 211 to tightly press against the connection point of the copper core wire 5, forming a uniform circumferential pressure to ensure that the connection is stable and insulated, preventing loosening or short circuit. The external threaded post 24 is fixed on both sides of the fixed plate 21, and its surface movable groove 25 allows the connecting rod 26 to pass through and move, ensuring the stability of rotational transmission. The seven sets of wiring protection holes 215 of the protective plate 28 are arranged in a circumferential array, and the six sets of push rods 29 in each set of holes are also arranged in a circumferential array. Through the mutual meshing of the pinion 214 and the drive of the large gear 27, multi-directional synchronous pressing is achieved, enhancing the protection effect. The anti-detachment structure 3 is used to prevent the cable 4 after wiring from being pulled off by external force. The rubber sleeve 31 is fitted on the outside of the carbon fiber reinforced protective sleeve 1 and fixed in position by the mounting buckle 32. A locking rod 34 is slidably connected to the inner side of the connecting plate 33. One end of the locking rod 34 is fixed to a locking block 35 for clamping the carbon fiber reinforced protective sleeve 1. A slider 36 on the surface of the locking rod 34 engages with an arc-shaped groove 38 on one side of the rotating plate 37. When the rotating plate 37 is rotated, the arc-shaped groove 38 drives the slider 36 to move, causing the locking rod 34 and the locking block 35 to slide towards the carbon fiber reinforced protective sleeve 1, thus achieving locking. A crossbar 39 is fixed to the surface of the rotating plate 37. The crossbar 39 is connected to an internal threaded sleeve 310. A telescopic rod 311 is inserted into the internal threaded sleeve 310. A linkage ring 312 is fixed to one end of the telescopic rod 311. A circular hole 313 on the surface of the linkage ring 312 is used for adjusting the position. A spring 314 is sleeved on the surface of the telescopic rod 311, with one end fixed to the linkage ring 312 and the other end fixed to the internal threaded sleeve 310, providing elastic cushioning. When cable 4 is subjected to external force, spring 314 compresses and absorbs energy to prevent sudden detachment. At the same time, the sliding of linkage ring 312 and telescopic rod 311 maintains a stable locking force. Overall, wiring protection structure 2 ensures the safety and reliability of electrical connections, while anti-detachment structure 3 provides mechanical tensile protection. The two work together to enable the cable to operate efficiently in low-temperature and tensile environments.
