Description

Technical Field

[0001] This invention relates to the field of power cable technology, specifically to an insulated, low-carbon, clean, and environmentally friendly power cable. Background Technology

[0002] Against the backdrop of energy transition and the advancement of "dual carbon" goals, the greening process of the power system is accelerating. Traditional power cables have problems such as high energy consumption and high pollution in the production, use and disposal stages, and can no longer adapt to the green and low-carbon development trend. In order to better protect the ecological environment and reduce energy consumption, people generally use insulated, low-carbon, clean and environmentally friendly power cables.

[0003] Existing low-carbon, clean, and environmentally friendly insulated power cables have the following shortcomings:

[0004] Insulated low-carbon clean and environmentally friendly power cables typically use multiple extra hooks to fix them to the suspension line. When the cable is damaged and needs to be replaced, the workers have to remove each hook one by one during the replacement process, which makes it impossible to quickly remove the entire cable. The operation process is cumbersome, which not only increases the labor intensity of the workers, but also increases their working time, thus reducing the effectiveness of the insulated low-carbon clean and environmentally friendly power cables.

[0005] Therefore, we propose an insulated, low-carbon, clean, and environmentally friendly power cable to address the problems mentioned in the background section. Summary of the Invention

[0006] The purpose of this invention is to provide an insulated, low-carbon, clean, and environmentally friendly power cable. By setting an auxiliary mechanism, the insulated, low-carbon, clean, and environmentally friendly power cable, which is fixed together with the suspension wire, can be quickly removed when being replaced.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an insulated, low-carbon, clean, and environmentally friendly power cable, comprising a cable body, characterized in that: an auxiliary mechanism is provided on the cable body;

[0008] The auxiliary mechanism includes two perforated shells, a cylindrical hole, two annular grooves, and two annular blocks. Both perforated shells have threaded holes. The cylindrical holes are used to accommodate steel wire ropes. Fixing members are provided at both ends of the steel wire rope. Each annular groove contains a first half-ring block and two second half-ring blocks. One end of each second half-ring block is hinged to one end of the first half-ring block. The other ends of the second and first half-ring blocks are bent and pre-formed circumferentially to form bent ends. Near the bent ends, placement grooves are formed on the inner walls of both the first and second half-ring blocks. A fixed cylindrical rod is fixed inside each placement groove. A portion of a locking block is rotatably connected to the fixed cylindrical rod and disposed within the placement groove. Bolts can also be detachably disposed within the placement grooves. When the locking block is connected to the bolt, its position within the placement groove is locked. When the locking block is separated from the bolt, the locking block rotates within the placement groove with the fixed cylindrical rod as its axis. The bent ends of each second half-ring block and the bent ends of the first half-ring block are movably sleeved on the outer surface of the steel wire rope.

[0009] Preferably, each of the annular grooves has two auxiliary grooves on its inner wall, and each of the first half-ring blocks has a retaining groove on its inner wall at the bent end, and each of the second half-ring blocks has a retaining groove for engaging with one end of the retaining block.

[0010] Preferably, the annular grooves are all connected to the cylindrical holes, and the wire rope passes through the threading holes.

[0011] Preferably, the four second semi-ring blocks are divided into two groups, and the connecting end of the second semi-ring block in each group is respectively installed with the connecting end of each first semi-ring block.

[0012] Preferably, the threaded end of each bolt passes through the inner wall of each placement slot, and the threaded end of each bolt moves through the surface of each locking block.

[0013] Preferably, one end of the locking block is engaged inside the locking groove, and the wire rope is movably sleeved between the inside of the two circular blocks.

[0014] Preferably, the cable body includes a sheath layer, three conductor cores, a reinforcing core, and multiple tensile cores. The inner wall of the sheath layer is provided with a water-resistant layer, and the inner wall of the water-resistant layer is provided with a shielding layer.

[0015] Preferably, the inner wall of the shielding layer is provided with an inner protective layer, the outer surface of each conductor core and the outer surface of the reinforcing core are provided with an insulating layer, and a buffer layer is provided between the outer surfaces of the four insulating layers.

[0016] Preferably, the inner wall of the buffer layer has multiple auxiliary holes, and a filling layer is provided between the inner wall of the inner protective layer and the buffer layer through the auxiliary holes.

[0017] Preferably, both annular grooves are formed on the outer wall of the sheath layer, the two perforated shells are respectively located at both ends of the sheath layer, each annular block is located inside the sheath layer, and the cylindrical hole is formed on one end face of the sheath layer.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (I) This invention, by setting up an auxiliary mechanism, allows the insulated low-carbon clean and environmentally friendly power cable, which is fixed together with the suspension line, to be quickly removed when it is replaced. The operation process is simple, which not only reduces the labor intensity of the workers, but also reduces their working time, thereby improving the performance of the insulated low-carbon clean and environmentally friendly power cable. When it is necessary to fix the cable body to the prepared suspension line, first fix both ends of the cable body and both ends of the wire rope to the two cable towers respectively. Then, by using the cooperation of the auxiliary groove and the annular groove, the screws between the connecting ends of each group of second half ring blocks and each connecting end of each first half ring block can be removed. Then, by using the cooperation of the annular groove, the placement groove, the locking block, the locking groove, the round rod and the bolt, each group of second half ring blocks and each first half ring block can be rotated around the wire rope as the center.

[0020] (II) Following this invention, by utilizing the pre-removed screws, the connecting end of each group of second half-ring blocks can be connected to the connecting end of each group of first half-ring blocks, ensuring the suspension line is positioned between each group of second half-ring blocks and each group of first half-ring blocks. Then, using the perforated shell, wire rope, cylindrical hole, fixing component, ring block, annular groove, wire hole, first half-ring block, second half-ring block, and screws, the cable body is fixed to the prepared suspension line. When the first half-ring block needs to be replaced, the corresponding bolt can be removed using the prepared tools. Then, by utilizing the corresponding round rod and the corresponding placement groove, the corresponding locking block can be separated from the corresponding locking groove.

[0021] (III) The present invention then utilizes the corresponding annular groove to separate the first half-ring block from the wire rope. After that, the above operation steps are followed to install the new first half-ring block back in its original position. When the cable body fixed on the suspension line needs to be replaced, one end of the cable body is first separated from the corresponding cable tower, then both ends of the wire rope are separated from the corresponding cable tower, and both fixing parts are removed. Then, by using the start-up winch, the two wire holes and the cylindrical hole, the wire rope can be separated from the cable body. Then, by using the cooperation of the first half-ring block, the annular groove and the second half-ring block, the cable body can be separated from the suspension line. Then, the other end of the cable body is separated from the corresponding cable tower, and then a new cable body can be laid directly.

[0022] (iv) By designing the cable body, this invention can reduce environmental pollution and greenhouse gas emissions. The sheath layer allows the cable body to maintain good flexibility and mechanical properties even in cold regions or low-temperature conditions, preventing brittleness. The water-resistant layer effectively prevents moisture from penetrating the cable body, thus avoiding insulation degradation caused by moisture. The shielding layer prevents external electromagnetic interference from entering the cable body, ensuring the stability and accuracy of signal transmission. The inner sheath protects the internal structure of the cable body from chemical corrosion, extending its service life. The conductor core reduces resistance and energy loss during transmission, improving power transmission efficiency.

[0023] (V) This invention improves the mechanical properties of the cable body by strengthening the core, thereby ensuring the structural stability of the cable body during laying and use. It effectively prevents current leakage and reduces power loss by the insulation layer, thereby ensuring the efficiency and safety of power transmission. It effectively buffers the impact of external mechanical stress on the internal structure of the cable body by the buffer layer, thereby protecting the internal insulation layer and conductor core of the cable body from damage. It effectively resists the compression of the internal structure of the cable by external pressure by the filling layer, thereby improving the reliability and safety of the cable body when subjected to external pressure. It provides strong tensile support for the cable body by the tensile core, thereby ensuring the structural integrity and electrical performance stability of the cable body. It allows the filling layer and the buffer layer to be tightly bonded together by the auxiliary holes. Attached Figure Description

[0040] 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.

[0041] Example 1: Please refer to Figures 1-8 , Figure 11 and Figure 12 As shown, the present invention provides a technical solution: an insulated, low-carbon, clean and environmentally friendly power cable, including a cable body 1, and an auxiliary mechanism 2 is provided on the cable body 1;

[0042] The auxiliary mechanism 2 includes two perforated shells 201, a cylindrical hole 202, two annular grooves 204, and two annular blocks 214. A sheath layer 101 is provided between adjacent perforated shells 201. Two annular grooves 204 are formed on the outer side of the sheath layer 101, each annular groove 204 occupying half the outer circumference of the sheath layer 101. An annular block 214 is also provided inside the sheath layer 101 near the annular grooves 204. A cylindrical hole 202 is also formed along the axial direction of the sheath layer 101.

[0043] Furthermore, each of the two perforated shells 201 has a wire hole 215 on its opposite side. A steel wire rope 203 is movably sleeved inside the cylindrical hole 202. Both ends of the steel wire rope 203 are provided with fixing members 213. Each annular groove 204 has a first half-ring block 206 and two second half-ring blocks 207 respectively inside. Each first half-ring block 206 and each second half-ring block 207 has a placement groove 208. A round rod 209 is fixed inside each placement groove 208 along the length direction. The outer surface of each round rod 209 is fitted with a locking block 210, so that the locking block 210 can rotate relative to the round rod 209. The bent end of each second half-ring block 207 and the bent end of the first half-ring block 206 are movably sleeved on the outer surface of the steel wire rope 203.

[0044] Furthermore, bolts 211 are provided in the placement grooves 208 of the first semi-ring block 206 and the second semi-ring block 207, respectively, and the bolts 211 penetrate the placement grooves 208. Two auxiliary grooves 205 are provided along the axial direction on the inner wall of each annular groove 204. The first half-ring block 206 is connected to one end of the locking block 210 and the second half-ring block 207 is connected to one end of the locking block 210, and both are provided with locking grooves 212. 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 wire 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 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. The threaded end of each bolt 211 is movable through the surface of each locking block 210. The locking end of each locking block 210 is movablely locked inside each locking groove 212. The wire rope 203 is movably sleeved between the interiors of the two annular blocks 214.

[0045] In this embodiment, when it is necessary to fix the cable body 1 to the prepared suspension line, firstly, fix both ends of the cable body 1 and both ends of the wire rope 203 to the two cable towers respectively. Then, using the cooperation of two auxiliary grooves 205, since the auxiliary grooves 205 are opened along the axial direction, and the screws ( Figure 3 As shown in the diagram, this screw-equipped structure needs to be positioned at the corresponding auxiliary slot 205. Remove the screws from the connecting ends of one set of second semi-ring blocks 207 and one set of first semi-ring blocks 206. Rotate one set of second semi-ring blocks 207 and one set of first semi-ring blocks 206 180 degrees around the steel wire rope 203, so that the suspension line (pre-fixed) is positioned between the two sets of second semi-ring blocks 207 and one set of first semi-ring blocks 206. Using the previously removed screws, fix the connecting ends of one set of second semi-ring blocks 207 and one set of first semi-ring blocks 206 together (e.g., ...). Figure 2 (As shown), then follow the above operating steps to hang the other set of second half-ring blocks 207 and the other set of first half-ring blocks 206 on the suspension line. At this time, with the cooperation of the perforated shell 201, wire rope 203, cylindrical hole 202, fixing part 213, ring block 214, annular groove 204, wire hole 215, first half-ring block 206, second half-ring block 207 and screws, the cable body 1 can be fixed on the prepared suspension line.

[0046] When one of the first half-ring blocks 206 needs to be replaced, first remove the screws between one of the first half-ring blocks 206 and the corresponding set of second half-ring blocks 207, 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. Then, use a tool to remove the bolt 211 on the first half-ring block 206, so that the locking block 210 is released from the locking state of the bolt 211. After the locking block 210 is unlocked, it can rotate around the round rod 209 as the axis and inside the placement groove 208 until the corresponding locking block 210 can no longer rotate. At this time, the locking end of the corresponding locking block 210 will move completely into the placement groove 208. The removal of the locking block 210 creates an opening at the bend of the first half-ring block 206. By rotating the first half-ring block 206, it can be separated from the wire rope 203. Then move the first half-ring block 206 to separate it from the wire rope 203, and then remove the first half-ring block 206 directly. Then, repeat the above steps to replace the other new first half-ring block 206. When one of the second half-ring blocks 207 needs to be replaced, simply follow the above replacement steps.

[0047] When the cable body 1 fixed to the suspension line needs to be replaced, firstly, 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 remove the two fixing parts 213. Next, connect the prepared winch to the end of the wire rope 203 away from the cable body 1, and then start the winch. The startled winch will slowly pull the wire rope 203 out from between the two wire holes 215 and the cylindrical hole 202. When the wire rope 203 is completely pulled out from between the cylindrical hole 202 and the two wire holes 215, the cable body 1 loses the traction support of the wire rope 203 and will naturally sag and fall under its own weight. The two first semi-ring blocks 206 and the two sets of second semi-ring blocks 207 are still connected to the suspension line through the hinge structure and are hung on the suspension line, thus realizing the cable body 1 After quickly separating from the suspension line, the other end of the cable body 1 is then separated from the corresponding cable tower, and a new cable body 1 is then laid.

[0048] Example 2: According to Figures 1-5 , Figure 9 and Figure 10As shown, the cable body 1 includes a sheath layer 101, three conductor cores 105, a reinforcing core 106, and multiple tensile cores 110. The inner wall of the sheath layer 101 is provided with a water-resistant layer 102, the inner wall of the water-resistant layer 102 is provided with a shielding layer 103, and the inner wall of the shielding layer 103 is provided with an inner sheath layer 104. The outer surface of each conductor core 105 and the outer surface of the reinforcing core 106 are provided with an insulation layer 107. A buffer layer 108 is provided between the outer surfaces of the four insulation layers 107. Multiple auxiliary holes 111 are opened on the inner wall of the buffer layer 108. A filling layer 109 is provided between the inner wall of the inner sheath layer 104 and the buffer layer 108 through the auxiliary holes 111.

[0049] In this embodiment, when the cable body 1 is used in a low-temperature environment, the sheath layer 101 maintains good flexibility and mechanical properties, preventing brittleness and ensuring normal operation of the cable body 1 in cold regions or low-temperature conditions. When the cable body 1 is used in a relatively humid environment, the water-resistant layer 102 effectively prevents moisture from entering the interior of the cable body 1, protecting the conductor core 105 and insulation layer 107 inside the cable body 1. When the cable body 1 is used in areas with high electromagnetic radiation, the shielding layer 103 effectively blocks external electromagnetic waves from interfering with the signals inside the cable body 1, ensuring the stability and reliability of power transmission. When the cable body 1 is in use, the inner sheath layer 104 effectively resists the erosion of various chemical substances, ensuring the reliability of the cable body 1 in various chemical environments. When the cable body 1 is in use, the conductor core 105 effectively reduces power loss during power transmission, improving energy utilization efficiency. It meets the requirements of low carbon and environmental protection. When the cable body 1 is used in sections with large spans such as crossing rivers and valleys, the reinforcing core 106 can help the cable body 1 withstand long-term tension and external friction, thereby improving the reliability and durability of the cable body 1. When the cable body 1 is in use, the insulation layer 107 can effectively reduce the loss during power transmission, improve power transmission efficiency, and reduce energy waste caused by heat generation, 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 external forces through its own soft deformation, thereby protecting the internal structure of the cable body 1. When the cable body 1 is subjected to external pressure, the filling layer 109 can effectively resist external mechanical stress and extend the service life of the cable body 1. When the cable body 1 is subjected to external tension, the tensile core 110 can cause the cable body 1 to deform to a certain extent without breaking, thereby absorbing and buffering external forces and protecting the other structural layers of the cable body 1.

[0050] The overall effect and working principle of the mechanism are as follows:

[0051] During the installation phase, when it is necessary to fix the cable body 1 to the prepared suspension line, first fix both ends of the cable body 1 and both ends of the wire rope 203 to the two cable towers respectively. Then, using the cooperation of two auxiliary grooves 205, since the auxiliary grooves 205 are opened along the axial direction, and the screws ( Figure 3 As shown in the diagram, this screw-equipped structure needs to be positioned at the corresponding auxiliary slot 205. Remove the screws from the connecting ends of one set of second semi-ring blocks 207 and one set of first semi-ring blocks 206. Rotate one set of second semi-ring blocks 207 and one set of first semi-ring blocks 206 180 degrees around the steel wire rope 203, so that the suspension line (pre-fixed) is positioned between the two sets of second semi-ring blocks 207 and one set of first semi-ring blocks 206. Using the previously removed screws, fix the connecting ends of one set of second semi-ring blocks 207 and one set of first semi-ring blocks 206 together (e.g., ...). Figure 2 (As shown), then follow the above operating steps to hang the other set of second half-ring blocks 207 and the other set of first half-ring blocks 206 on the suspension line. At this time, with the cooperation of the perforated shell 201, wire rope 203, cylindrical hole 202, fixing part 213, ring block 214, annular groove 204, wire hole 215, first half-ring block 206, second half-ring block 207 and screws, the cable body 1 can be fixed on the prepared suspension line.

[0052] 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 removed first, 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. Then, the bolt 211 on the first half-ring block 206 is removed with a tool, so that the locking block 210 is released from the locking state of the bolt 211. After the locking block 210 is unlocked, it can rotate around the round rod 209 as the axis and inside the placement groove 208 until the corresponding locking block 210 can no longer rotate. At this time, the locking end of the corresponding locking block 210 will move completely into the placement groove 208. The removal of the locking block 210 creates an opening at the bend of the first half-ring block 206. By rotating the first half-ring block 206, it can be separated from the wire rope 203. Then move the first half-ring block 206 so that it separates from the wire rope 203. Then remove the first half-ring block 206 directly. Then, reverse the operation steps for another new first half-ring block 206. When one of the second half-ring blocks 207 needs to be replaced, simply follow the replacement steps described above.

[0053] During the cable body 1 replacement phase, when the cable body 1 fixed to the suspension line needs to be replaced, firstly, one end of the cable body 1 is separated from the corresponding cable tower. Then, both ends of the wire rope 203 are separated from the corresponding cable tower, and the two fixing parts 213 are removed. Next, the prepared winch is connected to the end of the wire rope 203 away from the cable body 1. Then, the winch is started, and it slowly pulls the wire rope 203 out from between the two wire holes 215 and the cylindrical hole 202. When the wire rope 203 is completely pulled out from between the cylindrical hole 202 and the two wire holes 215, the cable body 1 loses the traction support of the wire rope 203 and will naturally sag and fall under its own weight. Meanwhile, the two first semi-ring blocks 206 and the two sets of second semi-ring blocks 207 remain connected to the suspension line through the hinge structure and are hung on the suspension line, thus realizing the replacement of the cable body 1. The cable body 1 is quickly separated from the suspension line, and then the other end of the cable body 1 is separated from the corresponding cable tower. Then a new cable body 1 can be laid.

[0054] In the layering stage of the cable body 1, when the cable body 1 is used in a low-temperature environment, the sheath layer 101 helps maintain good flexibility and mechanical properties, preventing brittleness and ensuring normal use of the cable body 1 in cold regions or low-temperature conditions. When the cable body 1 is used in a relatively humid environment, the water-resistant layer 102 effectively prevents moisture from entering the interior of the cable body 1, protecting the conductor core 105 and insulation layer 107 inside the cable body 1. When the cable body 1 is used in areas with high electromagnetic radiation, the shielding layer 103 effectively blocks external electromagnetic waves from interfering with the signals inside the cable body 1, ensuring the stability and reliability of power transmission. When the cable body 1 is in use, the inner sheath layer 104 effectively resists the corrosion of various chemical substances, ensuring the reliability of the cable body 1 in various chemical environments. When the cable body 1 is in use, the conductor core 105 effectively reduces power loss during power transmission and improves energy utilization efficiency. This design ensures the cable body 1 meets low-carbon and environmentally friendly requirements. When the cable body 1 is used in areas with large spans, such as crossing rivers and valleys, the reinforcing core 106 allows the cable body 1 to withstand long-term tension and external friction, thereby improving the reliability and durability of the cable body 1. When the cable body 1 is in use, the insulation layer 107 effectively reduces power loss during power transmission, improves power transmission efficiency, and reduces energy waste caused by heat generation, conforming to the low-carbon and environmentally friendly concept. When the cable body 1 is in use, the buffer layer 108 disperses external forces through its own soft deformation, thereby protecting the internal structure of the cable body 1. When the cable body 1 is subjected to external pressure, the filling layer 109 effectively resists external mechanical stress, extending the service life of the cable body 1. When the cable body 1 is subjected to external tension, the tensile core 110 allows the cable body 1 to deform to a certain extent without breaking, thereby absorbing and buffering external forces and protecting the other structural layers of the cable body 1.
