Detailed Implementation

[0030] 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.

[0031] Please see Figure 1-8This invention provides a technical solution: an aluminum core cross-linked polyethylene insulated overhead cable, comprising an overhead cable assembly 1, a connecting assembly 2 for connecting the overhead cable fixedly installed at one end of the overhead cable assembly 1, a sealing assembly 3 for maintaining the sealing performance of the connecting assembly 2 fixedly connected to the outer surface of the connecting assembly 2, and a fixing assembly 4 for fixing the overhead cable disposed near one end of the outer surface of the connecting assembly 2. The connecting assembly 2 includes a conductor tube 201, an insulating sleeve 202 fixedly sleeved on the outer surface of the conductor tube 201, a first sealing sleeve 205 abutting near the center of the outer surface of the insulating sleeve 202, a first spiral tube 204 fixedly connected to one side of the outer surface of the first sealing sleeve 205, and a first insulating clamp 203 rotatably connected to the inner wall of the first spiral tube 204. A first threaded tube 206 is spirally connected at the edge. The inner wall of the first insulating clamp 203 is in contact with the outer surface of the insulating sleeve 202. A second sealing sleeve 207 is in contact with the outer surface of the insulating sleeve 202 near the center. A second spiral tube 208 is fixedly connected to one side of the outer surface of the second sealing sleeve 207. A second insulating clamp 209 is rotatably connected to the inner wall of the second spiral tube 208. A second threaded tube 210 is spirally connected to the inner wall of the second spiral tube 208 near one edge. The inner wall of the second insulating clamp 209 is in contact with the outer surface of the insulating sleeve 202. The overhead cable assembly 1 includes an aluminum core body 101. A cross-linked polyethylene insulating tube 102 is fixedly sleeved on the outer surface of the aluminum core body 101. A plurality of fiber optic bundle tubes 103 for pressure resistance are fixedly embedded in the inner wall of the cross-linked polyethylene insulating tube 102.

[0032] like Figure 1-8As shown, when using an aluminum core cross-linked polyethylene insulated overhead cable, and it is necessary to connect the aluminum core cross-linked polyethylene insulated overhead cable to an external cable, the conductor portion of the external cable is inserted into the conductor tube 201 and fits against the conductor tube 201. Rotating the first spiral tube 204 causes the inner wall of the first sealing sleeve 205 to rotate and slide along the outer surface of the insulating sleeve 202. Simultaneously, as the inner wall of the first spiral tube 204 moves spirally along the outer surface of the first threaded tube 206, it also rotates along the outer surface of the first insulating clamp 203, driving the first insulating... As the first insulating chuck 203 moves, its clamping force increases as it moves inward toward the first threaded tube 206. This causes the first insulating chuck 203 to clamp the insulating sleeve 202, which in turn causes the conductor tube 201 to clamp the aluminum core body 101. Then, the second spiral tube 208 rotates, causing the inner wall of the second sealing sleeve 207 to slide and rotate along the outer surface of the insulating sleeve 202. Simultaneously, the inner wall of the second spiral tube 208 moves spirally along the outer surface of the second threaded tube 210. The rotation of the outer surface of the second insulating clamp 209 causes the second insulating clamp 209 to move. As the second insulating clamp 209 moves into the second threaded tube 210, its clamping force increases, thus clamping the insulating sleeve 202. The insulating sleeve 202 then causes the conductor tube 201 to clamp the conductor portion of the external overhead cable, effectively fixing the two overhead cables together. This device, by setting the connecting component 2, brings the conductor portion of the external overhead cable into contact with the interior of the conductor tube 201. Rotating the first spiral tube 204 and the second spiral tube 208, respectively, moves spirally along the outer surfaces of the first threaded tube 206 and the second threaded tube 210, causing the first insulating clamp 203 and the second insulating clamp 209 to clamp the conductor portion of the overhead cable with the conductor tube 201, thereby effectively fixing and connecting the two overhead cables. This avoids the need to use multiple tools when connecting two overhead cables, and solves the problem that the connection of overhead cables in the prior art involves multiple tools, resulting in a long construction time and high complexity in the connection process.

[0033] In this embodiment, the outer surface of the aluminum core body 101 is in contact with the inner wall of the conductor tube 201. One end of the first threaded tube 206 is fixedly connected to one end of the cross-linked polyethylene insulating tube 102. The sealing assembly 3 includes two fixing blocks 301. The outer surface of one fixing block 301 is fixedly connected to the first spiral tube 204, and the outer surface of the other fixing block 301 is fixedly connected to the outer surface of the second spiral tube 208. The inner walls of both fixing blocks 301 are movably fitted with rotating shafts 311. The outer surfaces of the two rotating shafts 311 are fixedly fitted with rotating rods 302 near the center. One end of each rotating rod 302 is fixedly connected to a first fixing shaft 303. The outer surfaces of both first fixing shafts 303 are fixedly fitted with moving blocks 304. One side of the outer surface of one moving block 304 is fixedly connected to a first arc plate 305. One side of the outer surface of the first arc plate 305 is fixedly connected to a first rubber block 306. The other side of the outer surface of the first arc plate 305 is fixedly connected to a first heat dissipation device. A second arc plate 308 is fixedly connected to one side of the outer surface of the plate 307 and another movable block 304. A second heat sink 309 is fixedly connected to one side of the outer surface of the second arc plate 308. A second rubber block 310 is fixedly connected to the other side of the outer surface of the second arc plate 308. Ratchets 312 are fixedly sleeved on the outer surfaces of the two rotating shafts 311. A second fixed shaft 313 is movably embedded in the inner wall of the two fixed blocks 301. A limiting plate 314 is fixedly sleeved on the outer surface of the two second fixed shafts 313. The outer surfaces of the two limiting plates 314 are respectively in contact with the outer surfaces of the two ratchet 312. A first spring 315 is provided on the outer surface of the two limiting plates 314. One end of the two first springs 315 is fixedly connected to the outer surface of the two limiting plates 314, and the other end of the two first springs 315 is fixedly connected to the inner wall of the two fixed blocks 301. The fixing assembly 4 includes a slide tube 401. The inner wall of the slide tube 401 is slidably connected to the outer surface of the second spiral tube 208.

[0034] like Figure 1-8As shown, when an aluminum core cross-linked polyethylene insulated overhead cable is in use, after the conductor portion of the overhead cable is clamped to the conductor tube 201 by the first insulating clamp 203 and the second insulating clamp 209, the distance between the first sealing sleeve 205 and the second sealing sleeve 207 increases. At this time, the operator rotates the rotating rod 302, which drives the outer surface of the rotating shaft 311 to rotate along the inner wall of the fixed block 301. Simultaneously, the rotating shaft 311 drives the ratchet 312 to rotate. When the ratchet 312 rotates, it lifts the limiting plate 314. The limiting plate 314 drives the second fixed shaft 313 to rotate while simultaneously squeezing the first spring 315 until the ratchet... The lifting force of 312 on the limiting plate 314 gradually decreases. At this time, the elastic force of the first spring 315 will cause the outer surface of the limiting plate 314 to fit against the outer surface of the ratchet 312. Simultaneously, when the rotating rod 302 moves, it will drive the first fixed shaft 303 to move. The first fixed shaft 303 will drive the moving block 304 to move. One of the moving blocks 304 will drive the first arc plate 305 to move. The first arc plate 305 will cause the outer surface of the first rubber block 306 to fit against the outer surface of the insulating sleeve 202. At the same time, the two sides of the outer surface of the first rubber block 306 will fit against the first sealing sleeve 205 and the second sealing sleeve 207 respectively. The outer surface of the first arc plate 305 will also fit against the first sealing sleeve 205 and the second sealing sleeve 207. The outer surfaces of the sleeve 205 and the second sealing sleeve 207 are in contact with each other. Then, another moving block 304 will drive the second arc plate 308 to move. The second arc plate 308 will drive the outer surface of the second rubber block 310 to be in contact with the outer surface of the insulating sleeve 202. At the same time, both sides of the outer surface of the second rubber block 310 are in contact with the first sealing sleeve 205 and the second sealing sleeve 207 respectively. The outer surface of the second arc plate 308 will also be in contact with the outer surfaces of the first sealing sleeve 205 and the second sealing sleeve 207. At this time, the outer surface of the second rubber block 310 is in contact with the outer surface of the first rubber block 306. Meanwhile, during the process of energizing the overhead cable, the temperature will gradually rise, and the increased temperature will... The heat is transferred through the second rubber block 310 and the first rubber block 306 to the first arc plate 305 and the second arc plate 308, and then through the first arc plate 305 and the second arc plate 308 to the first heat dissipation plate 307 and the second heat dissipation plate 309 for heat dissipation. By setting the sealing component 3, after the two overhead cables are connected, the outer surfaces of the first rubber block 306 and the second rubber block 310 are brought into contact with the gap between the first sealing sleeve 205 and the insulating sleeve 202 and the second sealing sleeve 207 and the insulating sleeve 202 by moving the rotating rod 302. This can effectively block the intrusion of moisture, dust and corrosive gases and improve the sealing effect of the connecting component 2.

[0035] In this embodiment, a stop 403 is fixedly connected to the inner wall of the slide tube 401, and a second spring 402 is provided on the outer surface of the stop 403. One end of the second spring 402 is fixedly connected to the outer surface of the second spiral tube 208, and the other end of the second spring 402 is fixedly connected to the outer surface of the stop 403. A fixing plate 404 is fixedly connected to one end of the second threaded tube 210. A plurality of evenly arranged spheres 405 are slidably connected to the inner wall of the fixing plate 404, and a sealing ring 406 is fixedly connected to one end of the fixing plate 404.

[0036] like Figure 1-8 As shown, when using an aluminum core cross-linked polyethylene insulated overhead cable, if two overhead cables are connected, moving the slide tube 401 causes the inner wall of the slide tube 401 to slide along the outer surface of the second spiral tube 208, simultaneously moving the stop block 403 to press the second spring 402. When the stop block 403 is no longer in contact with the ball 405, the outer overhead cable is moved, bringing the conductor portion of the outer overhead cable into contact with the inner wall of the conductor tube 201. At this point, the outer portion of the outer overhead cable, located inside the fixing plate 404, pushes the ball 405 towards the slide tube 401. The operator then stops pressing the slide tube 401. 01. The elastic force of the second spring 402 will drive the stop block 403 to move. When the stop block 403 moves, it will drive the slide tube 401 to move until the outer surface of the stop block 403 contacts the ball 405. This will squeeze the outer surface of the ball 405 against the outer surface of the overhead cable, so that multiple balls 405 clamp the outer surface of the overhead cable, thereby fixing the overhead cable. This device, by setting the fixing component 4, moves the slide tube 401 to make the balls 405 engage with the outer surface of the overhead cable, thereby fixing the overhead cable and enhancing the reliability of the connection between the two overhead cables.

[0037] The usage and working principle of this device are as follows: When using an aluminum core cross-linked polyethylene insulated overhead cable, when connecting two overhead cables, the sliding tube 401 is moved. The inner wall of the sliding tube 401 slides along the outer surface of the second spiral tube 208, simultaneously moving the stop block 403 to compress the second spring 402. When the stop block 403 is no longer in contact with the ball 405, the outer overhead cable is moved, bringing the conductor portion of the outer overhead cable into contact with the inner wall of the conductor tube 201. At this time, the outer part of the outer overhead cable, located inside the fixed plate 404, pushes the ball 405 towards the sliding tube 401. When the operator stops pressing the sliding tube 401, the elastic force of the second spring 402 causes the stop block 403 to move. During movement, the slide tube 401 moves until the outer surface of the stop 403 contacts the ball 405. This causes the outer surface of the ball 405 to press against the outside of the overhead cable, resulting in multiple balls 405 clamping the outside of the overhead cable. Next, the first spiral tube 204 rotates, causing the inner wall of the first sealing sleeve 205 to slide and rotate along the outer surface of the insulating sleeve 202. As the inner wall of the first spiral tube 204 moves spirally along the outer surface of the first threaded tube 206, it simultaneously rotates along the outer surface of the first insulating clamp 203, causing the first insulating clamp 203 to move. As the first insulating clamp 203 moves inwards towards the first threaded tube 206, the clamping force of the first insulating clamp 203 increases. The first insulating clamp 203 clamps the insulating sleeve 202, which in turn causes the conductor tube 201 to clamp the aluminum core body 101. Then, the second spiral tube 208 rotates, causing the inner wall of the second sealing sleeve 207 to slide and rotate along the outer surface of the insulating sleeve 202. As the inner wall of the second spiral tube 208 moves spirally along the outer surface of the second threaded tube 210, it simultaneously rotates along the outer surface of the second insulating clamp 209, causing the second insulating clamp 209 to move. As the second insulating clamp 209 moves inward into the second threaded tube 210, its clamping force increases, thus clamping the insulating sleeve 202. The insulating sleeve 202 then causes the conductor tube 201 to clamp the aluminum core body 101. The tube 201 clamps the conductor portion of the external overhead cable, effectively fixing the two overhead cables together. At this point, the distance between the first sealing sleeve 205 and the second sealing sleeve 207 increases. The operator then rotates the rotating rod 302, causing the outer surface of the rotating shaft 311 to rotate along the inner wall of the fixing block 301. Simultaneously, the rotating shaft 311 drives the ratchet 312 to rotate. As the ratchet 312 rotates, it lifts the limiting plate 314. The limiting plate 314 then drives the second fixing shaft 313 to rotate, simultaneously compressing the first spring 315. This continues until the lifting force of the ratchet 312 on the limiting plate 314 gradually decreases. At this point, the elastic force of the first spring 315 causes the outer surface of the limiting plate 314 to come into contact with the outer surface of the ratchet 312.Simultaneously, as the rotating rod 302 moves, it drives the first fixed shaft 303 to move, which in turn drives the moving blocks 304 to move. One of the moving blocks 304 drives the first arc plate 305 to move, causing the outer surface of the first rubber block 306 to come into contact with the outer surface of the insulating sleeve 202. At the same time, both sides of the outer surface of the first rubber block 306 come into contact with the first sealing sleeve 205 and the second sealing sleeve 207, respectively. The outer surface of the first arc plate 305 also comes into contact with the outer surfaces of the first sealing sleeve 205 and the second sealing sleeve 207. Then, the other moving block 304 drives the second arc plate 308 to move, causing the outer surface of the second rubber block 310 to come into contact with... When the outer surface of the insulating sleeve 202 is in contact with the first sealing sleeve 205 and the second sealing sleeve 207, the outer surfaces of the second rubber block 310 are respectively in contact with both sides. The outer surface of the second arc plate 308 is also in contact with the outer surfaces of the first sealing sleeve 205 and the second sealing sleeve 207. At this time, the outer surface of the second rubber block 310 is in contact with the outer surface of the first rubber block 306. Simultaneously, during the energization of the overhead cable, the temperature gradually increases. This increased temperature is transferred through the second rubber block 310 and the first rubber block 306 to the first arc plate 305 and the second arc plate 308, and then through the first arc plate 305 and the second arc plate 308 to the first heat dissipation plate 307 and the second heat dissipation plate 309 for heat dissipation.
