[0023] Example 1: Please refer to Figures 1-8 、 Figure 11 and Figure 12As shown, the present invention provides a technical solution: an insulated low-carbon clean environmentally friendly power cable, comprising a cable body 1, on which an auxiliary mechanism 2 is provided; The auxiliary mechanism 2 comprises two perforated shells 201, a cylindrical hole 202, two annular grooves 204, and two annular blocks 214. A jacket layer 101 is located between two adjacent perforated shells 201. Two annular grooves 204 are defined on the outer side of the jacket layer 101, each occupying half the outer circumference of the jacket layer 101. An annular block 214 is further defined within the jacket layer 101, near the annular grooves 204. A cylindrical hole 202 is also defined along the axis of the jacket layer 101.

[0024] Furthermore, threading holes 215 are provided on the opposite sides of the two perforated shells 201, and the steel wire rope 203 is movably sleeved inside the cylindrical hole 202. Fixing parts 213 are provided at both ends of the steel wire rope 203. A first half-ring block 206 and two second half-ring blocks 207 are respectively provided inside each annular groove 204. A placement groove 208 is provided on each first half-ring block 206 and each second half-ring block 207. A round rod 209 is fixed inside each placement groove 208 along the length direction. The outer surface of each round rod 209 cooperates with a clamping block 210 so that the clamping block 210 can rotate relative to the round rod 209.

[0025] Furthermore, bolts 211 are provided in the placement groove 208 of the first half-ring block 206 and the placement groove 208 of the second half-ring block 207 , and the bolts 211 pass through the placement grooves 208 respectively. Two auxiliary grooves 205 are provided on the inner wall of each annular groove 204 along the axial direction. A clamping groove 212 is provided on one end of the first half-ring block 206 connected to the clamping block 210 and one end of the second half-ring block 207 connected to the clamping block 210. The interior of each annular groove 204 is connected to the interior of the cylindrical hole 202. The wire rope 203 is inserted into and passes through the threading hole 215. The four second half-ring blocks 207 are divided into two groups. The connecting end of each group of second half-ring blocks 207 is respectively installed with the connecting end of each first half-ring block 206 by screws. The threaded end of each bolt 211 is threaded through the inner wall of each placement groove 208 respectively. The threaded end of each bolt 211 is movably passed through the surface of each clamping block 210 respectively. The clamping end of each clamping block 210 is movably clamped in the interior of each clamping groove 212. The wire rope 203 is movably sleeved between the interiors of the two circular ring blocks 214.

[0026] In this embodiment, when the cable body 1 needs to be fixed on the prepared suspension line, the two ends of the cable body 1 and the two ends of the wire rope 203 are first fixed on the two cable towers respectively, and then the two auxiliary grooves 205 are used to cooperate. Since the auxiliary grooves 205 are opened along the axial direction, and the screws (as shown in the figure, it is clear that the structure with screws needs to be set at the position corresponding to the auxiliary grooves 205) are used to remove the screws on the connecting end of one group of second half-ring blocks 207 and the connecting end of one of the first half-ring blocks 206, and one group of second half-ring blocks 207 and one of the first half-ring blocks 206 are rotated 180 degrees with the wire rope 203 as the center, and the suspension line (fixed in advance) is placed between the inside of one group of second half-ring blocks 207 and one of the first half-ring blocks 206, and the screws removed first are used to fix the connecting end of one group of second half-ring blocks 207 and the connecting end of one of the first half-ring blocks 206 together (as shown in the figure). Figure 2 As shown), then follow the above steps to hang another set of second half ring blocks 207 and another first half ring block 206 on the suspension line. At this time, the cable body 1 can be fixed on the prepared suspension line with the cooperation of the perforated shell 201, wire rope 203, cylindrical hole 202, fixing piece 213, circular ring block 214, annular groove 204, threading hole 215, first half ring block 206, second half ring block 207 and screws.

[0027] When one of the first half-ring blocks 206 needs to be replaced, the screws between one of the first half-ring blocks 206 and the corresponding set of second half-ring blocks 207 are first removed, so that the connecting end of one of the first half-ring blocks 206 is separated from the connecting end of the corresponding set of second half-ring blocks 207, and then the bolt 211 on the first half-ring block 206 is removed with a tool, so that the clamping block 210 is released from the locked state of the bolt 211. After the clamping block 210 is unlocked, it can be rotated inside the placement groove 208 with the round rod 209 as the axis until the corresponding clamping block 210 cannot rotate. At this time, the clamping end of the corresponding clamping block 210 will be completely moved to the inside of the placement groove 208. The removal of the clamping block 210 forms an opening at the bend of the first half-ring block 206, and the first half-ring block 206 can be separated from the wire rope 203 by rotating it. Then move the first half ring block 206 so that it is separated from the wire rope 203, and then directly remove the first half ring block 206, and then replace another new first half ring block 206 with the reverse operation according to the above operation steps. When one of the second half ring blocks 207 needs to be replaced, just follow the above replacement steps.

[0028] When the cable body 1 fixed on the suspension line needs to be replaced, first separate one end of the cable body 1 from the corresponding cable tower, then separate both ends of the wire rope 203 from the corresponding cable tower, and at the same time remove the two fixing parts 213, then connect the prepared winch to the end of the wire rope 203 away from the cable body 1, and then start the winch. At this time, the started winch will slowly pull the wire rope 203 out from between the two threading holes 215 and the inside of the cylindrical hole 202. When the wire rope 203 is completely pulled out from between the cylindrical hole 202 and the inside of the two threading holes 215, the cable body 1 loses the traction support of the wire rope 203 and will naturally droop and fall under the action of its own gravity, while the two first half ring blocks 206 and the two groups of second half ring blocks 207 are still connected with the suspension line through the hinged structure and hung on the suspension line, thereby realizing the cable body 1 Quickly separate the cable body 1 from the suspension wire, then separate the other end of the cable body 1 from the corresponding cable tower, and then lay a new cable body 1.

[0029] Example 2: According to Figure 1-Figure 5 、 Figure 9 and Figure 10 As shown, the cable body 1 includes a sheath layer 101, three conductors 105, a reinforcement core 106 and multiple tensile cores 110, a water-resistant layer 102 is provided on the inner wall of the sheath layer 101, a shielding layer 103 is provided on the inner wall of the water-resistant layer 102, an inner protective layer 104 is provided on the inner wall of the shielding layer 103, an insulating layer 107 is provided on the outer surface of each conductor 105 and the outer surface of the reinforcement core 106, a buffer layer 108 is provided between the outer surfaces of the four insulating layers 107, a plurality of auxiliary holes 111 are opened on the inner wall of the buffer layer 108, and a filling layer 109 is provided between the inner wall of the inner protective layer 104 and the buffer layer 108 through the auxiliary holes 111.

[0030] In this embodiment, when the cable body 1 is used in a low-temperature environment, the sheath layer 101 can maintain good flexibility and mechanical properties, and is not prone to brittle cracking, thereby ensuring that the cable body 1 can be used normally in cold areas or low-temperature working conditions. When the cable body 1 is used in a relatively humid environment, the water-resistant layer 102 can effectively prevent moisture from entering the interior of the cable body 1, thereby protecting the conductor core 105 and the insulation layer 107 inside the cable body 1. When the cable body 1 is used in a place with high electromagnetic radiation, the shielding layer 103 can effectively block the interference of external electromagnetic waves on the internal signal of the cable body 1, thereby ensuring the stability and reliability of power transmission. When the cable body 1 is in use, the inner sheath 104 can effectively resist the erosion of various chemical substances, thereby ensuring the reliability of the cable body 1 in various chemical environments. When the cable body 1 is in use, the conductor core 105 can effectively reduce the loss in the power transmission process, improve energy utilization efficiency, and make It meets the requirements of low carbon and environmental protection. When the cable body 1 is used in areas with large spans such as across rivers and valleys, the cable body 1 can withstand long-term stretching and external friction under the action of the strengthening core 106, thereby improving the reliability and durability of the cable body 1. When the cable body 1 is in use, the insulating layer 107 can effectively reduce the loss in the process of power transmission, improve the power transmission efficiency, and reduce energy waste caused by heat, which is in line with the concept of low carbon and environmental protection. When the cable body 1 is in use, the buffer layer 108 can disperse the external force through its own soft deformation, thereby protecting the internal structure of the cable body 1. When the cable body 1 is squeezed by external force, the filling layer 109 can effectively resist the external mechanical stress and extend the service life of the cable body 1. When the cable body 1 is stretched by external force, the tensile core 110 can cause the cable body 1 to deform to a certain extent without breaking, thereby absorbing and buffering the external force and protecting other structural layers of the cable body 1.

[0031] The effect and working principle of the entire mechanism are as follows: During the installation phase, when the cable body 1 needs to be fixed on the prepared suspension line, the two ends of the cable body 1 and the two ends of the wire rope 203 are first fixed on the two cable towers respectively, and then the two auxiliary grooves 205 are used to cooperate. Since the auxiliary groove 205 is opened along the axial direction, and the screws (as shown in the figure, it is clear that the structure with screws needs to be set at the position corresponding to the auxiliary groove 205) are used to remove the screws on the connecting end of one group of second half-ring blocks 207 and the connecting end of one of the first half-ring blocks 206, and one group of second half-ring blocks 207 and one of the first half-ring blocks 206 are rotated 180 degrees with the wire rope 203 as the center, and the suspension line (fixed in advance) is between the inside of one group of second half-ring blocks 207 and one of the first half-ring blocks 206, and the connecting end of one group of second half-ring blocks 207 and the connecting end of one of the first half-ring blocks 206 are fixed together using the screws taken out first (as shown in the figure). Figure 2 As shown), then follow the above steps to hang another set of second half ring blocks 207 and another first half ring block 206 on the suspension wire. At this time, the cable body 1 can be fixed on the prepared suspension wire with the cooperation of the perforated shell 201, the wire rope 203, the cylindrical hole 202, the fixing member 213, the circular ring block 214, the annular groove 204, the threading hole 215, the first half ring block 206, the second half ring block 207 and the screws; During the half-ring block replacement stage, when one of the first half-ring blocks 206 needs to be replaced, the screws between one of the first half-ring blocks 206 and the corresponding set of second half-ring blocks 207 are first removed, so that the connection end of one of the first half-ring blocks 206 is separated from the connection end of the corresponding set of second half-ring blocks 207, and then the bolt 211 on the first half-ring block 206 is removed with a tool, so that the clamping block 210 is released from the locked state of the bolt 211. After the clamping block 210 is unlocked, it can be rotated inside the placement groove 208 with the round rod 209 as the axis until the corresponding clamping block 210 cannot rotate. At this time, the clamping end of the corresponding clamping block 210 will be completely moved to the inside of the placement groove 208. The removal of the clamping block 210 forms an opening at the bend of the first half-ring block 206, and the first half-ring block 206 can be separated from the wire rope 203 by rotating it. Then, move the first half ring block 206 to separate it from the wire rope 203, and then directly remove the first half ring block 206. Then, replace the other first half ring block 206 with another new one by performing the above-mentioned operation steps in reverse. When one of the second half ring blocks 207 needs to be replaced, simply follow the above-mentioned replacement steps. During the replacement stage of the cable body 1, when the cable body 1 fixed on the suspension line needs to be replaced, one end of the cable body 1 is first separated from the corresponding cable tower, and then both ends of the wire rope 203 are separated from the corresponding cable tower, and the two fixing parts 213 are removed at the same time, and then the prepared winch is connected to the end of the wire rope 203 away from the cable body 1, and then the winch is started. At this time, the started winch will slowly pull the wire rope 203 out from between the two threading holes 215 and the inside of the cylindrical hole 202. When the wire rope 203 is completely pulled out from between the cylindrical hole 202 and the inside of the two threading holes 215, the cable body 1 loses the traction support of the wire rope 203 and will naturally droop and fall under the action of its own gravity, while the two first half ring blocks 206 and the two groups of second half ring blocks 207 are still connected with the suspension line through the hinged structure and hung on the suspension line, thereby realizing the cable body 1 Quickly separate the cable from the suspension wire, then separate the other end of the cable body 1 from the corresponding cable tower, and then lay a new cable body 1; During the layering stage of the cable body 1, when the cable body 1 is used in a low-temperature environment, the sheath layer 101 can maintain good flexibility and mechanical properties and is not prone to brittle cracking, thereby ensuring that the cable body 1 can be used normally in cold areas or low-temperature working conditions. When the cable body 1 is used in a relatively humid environment, the water-resistant layer 102 can effectively prevent moisture from entering the interior of the cable body 1, thereby protecting the conductor core 105 and the insulation layer 107 inside the cable body 1. When the cable body 1 is used in places with high electromagnetic radiation, the shielding layer 103 can effectively block external electromagnetic waves from interfering with the internal signals of the cable body 1, thereby ensuring the stability and reliability of power transmission. When the cable body 1 is in use, the inner sheath 104 can effectively resist the erosion of various chemical substances, thereby ensuring the reliability of the cable body 1 in various chemical environments. When the cable body 1 is in use, the conductor core 105 can effectively reduce the loss during power transmission and improve energy utilization efficiency. , so that it meets the requirements of low carbon and environmental protection. When the cable body 1 is used in areas with large spans such as across rivers and valleys, the cable body 1 can withstand long-term stretching and external friction under the action of the strengthening core 106, thereby improving the reliability and durability of the cable body 1. When the cable body 1 is in use, the insulating layer 107 can effectively reduce the loss in the process of power transmission, improve the power transmission efficiency, and reduce the energy waste caused by heat, which is in line with the concept of low carbon and environmental protection. When the cable body 1 is in use, the buffer layer 108 can disperse the external force through its own soft deformation, thereby protecting the internal structure of the cable body 1. When the cable body 1 is squeezed by external force, the filling layer 109 can effectively resist the external mechanical stress and extend the service life of the cable body 1. When the cable body 1 is stretched by external force, the tensile core 110 can cause the cable body 1 to deform to a certain extent without breaking, thereby absorbing and buffering the external force and protecting other structural layers of the cable body 1.
