Description

Technical Field

[0001] The present invention relates to the technical field of power maintenance, and particularly relates to a wiring device and method for power maintenance. Background Art

[0002] In the daily operation and maintenance of the power system, power maintenance is an important link to ensure the safe and stable operation of the power grid. Power maintenance work mainly includes regular maintenance, inspection, repair and upgrade of power equipment to ensure its normal operation, improve reliability and safety, and extend the service life of the equipment. During the maintenance process, when it comes to the maintenance of power lines, problems such as cable aging or damage are often encountered. These cables, due to being exposed to the natural environment for a long time and affected by factors such as ultraviolet rays and temperature changes, may experience situations such as aging, cracking of the insulation layer or damage to the internal battery cores. When it is found that the cable is aged or damaged, in order to ensure the safety and reliability of power transmission, it is usually necessary to locally replace the damaged part. This process first requires cutting the entire cable to remove the damaged part. After cutting, in order to connect the new cable section, a part of the outer protective sleeve on the original cable must be cut off to expose the internal battery cores, and then the battery cores are screwed together. After completing the connection of the battery cores, it is necessary to wrap insulating tape around the wiring point for insulation wrapping; When the insulating tape is exposed to the natural environment for a long time, it will gradually age due to ultraviolet irradiation, temperature changes and humidity effects, resulting in a decrease in the viscosity of the insulating tape and a decline in its insulation performance. The aged insulating material may not be able to effectively prevent current leakage, increasing the risks of electric shock and short circuit.

[0003] To solve the above problems, a wiring device and method for power maintenance are proposed in this application. Summary of the Invention

[0004] The present invention provides a wiring device and method for power maintenance, which solves the problem that in the related art, when the insulating tape is exposed to the natural environment for a long time, it will gradually age due to ultraviolet irradiation, temperature changes and humidity effects, resulting in a decrease in the viscosity of the insulating tape and a decline in its insulation performance. The aged insulating material may not be able to effectively prevent current leakage, increasing the risks of electric shock and short circuit.

[0007] As a further optimized scheme of the present invention, the capsule insulation member includes a capsule cylinder. The capsule cylinder is arranged in the shaft cylinder.

[0008] As a further optimized scheme of the present invention, the cylindrical metal component includes a metal cylinder body. One adjacent end of the two shaft cylinders is connected with a metal cylinder body, and the metal cylinder body is communicated with the shaft cylinder. The two metal cylinder bodies are both located in the junction box. Conductive blocks are fixed at one adjacent end of the two metal cylinder bodies. The two conductive blocks are in mutual contact. A bearing block that fits against the bottoms of the two metal cylinder bodies is installed in the junction box.

[0009] As a further optimized scheme of the present invention, the elastic air guiding component includes an air cylinder. The two air cylinders are respectively installed at both ends in the junction box and are arranged vertically. The top end of the air cylinder extends out of the top of the junction box. An elastic piston member connected with the pressing component is installed in the air cylinder. An air hole is opened at the top of the air cylinder. An air supply pipe is connected to the bottom of the air cylinder. One end of the air supply pipe far away from the air cylinder is connected with a first joint. The two first joints are respectively installed at both ends of the junction box. A second joint is detachably connected to the first joint. A gas guiding hose is connected to the end of the second joint. The two gas guiding hoses are respectively communicated with the two capsule cylinders. A valve body is installed on the gas guiding hose.

[0010] As a further optimized scheme of the present invention, the elastic piston member includes a first piston, a shaft tube and a first spring. The first piston is slidably arranged in the air cylinder. The shaft tube slidably passes through the top of the air cylinder and through the bottom end of the first piston. The first piston is fixedly connected with the shaft tube, and the top end of the shaft tube is connected with the pressing component. The first spring is sleeved on the shaft tube, and both ends of the first spring are respectively connected with the top of the air cylinder and the pressing component. The pushing member includes a second piston, a handle rod, a sleeve shaft and a second bolt. The second piston is slidably disposed within the shaft tube. The handle rod is mounted on the second piston, and the top end of the handle rod slidably passes through the top end of the shaft tube. The sleeve shaft is sleeved on the handle rod and connected to the pressing assembly. The second bolt is threadedly connected to the sleeve shaft and presses against the handle rod. A through hole is formed at the top end of the shaft tube.

[0011] As a further optimized solution of the present invention, the pressing assembly includes a pressing plate and a pressing rod. Two pressing rods extending into the wiring box are inserted into the wiring box. The two pressing rods are respectively located above the two metal cylinders. A head is mounted at the bottom end of the pressing rod. The pressing plate is mounted at the top ends of the two pressing rods. The shaft tube and the first spring are both connected to the bottom of the pressing plate. The sleeve shaft is connected to the top of the pressing plate. The pressing plate is driven to move downward by a screw assembly.

[0012] As a further optimized solution of the present invention, the screw assembly includes a first screw, a conductive rod, a second screw and a nut. The first screw threadedly passes through the pressing plate and the top of the wiring box and is located above the conductive block.

A nut pressing against the bottom of the wiring box is threadedly sleeved on the second screw. A knob disk located above the pressing plate is mounted at the top end of the first screw.

[0013] As a further optimized solution of the present invention, elastic pressing assemblies are mounted at the opposite ends of the two shaft cylinders, and the elastic pressing assemblies are used for pressing the battery cells. The elastic pressing assembly includes a shaft sleeve. The two shaft sleeves are respectively mounted at the opposite ends of the two shaft cylinders. Two arc-shaped blocks are symmetrically disposed within the shaft sleeve. A pressing channel adapted to press the battery cells is formed between the two arc-shaped blocks.

A second spring is sleeved on the pressing rod, and the two ends of the second spring are respectively connected to the shaft sleeve and the end block.

[0014] A wiring method for power maintenance uses the above-mentioned wiring device for power maintenance and includes the following steps: Step 1: Cut off the damaged part of the cable, and then cut off a part of the insulating sleeves at the opposite ends of the cable to expose the battery cells. Step 2: Insert the battery cells of the two sections of the cable into the two elastic pressing assemblies at the two ends of the wiring box respectively, and press the battery cells by pressing the elastic pressing assemblies to prevent the battery cells from being scattered. Step 3: After pressing the battery cells, pass the battery cells of the two cables through two bladder docking components respectively and insert them into the corresponding metal cylinders; Step 4: Drive the pressing component to move downward by the screw component to punch the metal cylinder. After the metal cylinder deforms under the punching pressure, it squeezes the battery cells inside it to complete the fixation of the battery cells; Step 5: When the pressing component moves downward, it can push the elastic air guiding component to move downward, conduct the gas inside it to the bladder cylinder, causing the bladder cylinder to bulge and seal the connection between the metal cylinder and the cable; Step 6: When the bladder cylinder bulges and presses against the cable, the pressure sensor on the inner wall of the insulating tape layer can monitor the pressing force. After the pressing force exceeds the preset threshold of the pressure sensor, the pressure sensor transmits the detected pressure change signal to the controller. The controller makes a judgment according to the preset pressure threshold and issues an alarm through the alarm. At this time, the staff releases the air through the valve body on the air guiding hose, so that the gas in the bladder cylinder returns to the standard volume. When the bladder cylinder does not fit the cable and the gas inside it is less than the standard volume, the air can be pushed downward by the air pushing part, and the gas is pushed through the shaft tube into the air cylinder. The gas enters the bladder cylinder along the air supply pipe and the air guiding hose, increasing the gas volume in the bladder cylinder and making the bladder cylinder fit tightly with the cable.

[0015] The above technical solution of the present invention has the following beneficial technical effects: 1. The present invention cuts off the damaged part of the cable, then cuts off a part of the insulating sleeves at both ends of the cable to expose the battery cells, passes the battery cells of the two cables through two bladder docking components respectively and inserts them into the corresponding cylindrical metal components. The screw component drives the pressing component to move downward to punch the cylindrical metal component. After the cylindrical metal component deforms under the punching pressure, it squeezes the battery cells inside it to complete the fixation of the battery cells. When the pressing component moves downward, it can push the elastic air guiding component to move downward, conduct the gas inside it to the bladder docking component, causing the bladder docking component to bulge and seal the connection between the cylindrical metal component and the cable. This sealing method can more effectively isolate external moisture, dust, and impurities compared with traditional tapes or sealants, preventing these substances from entering the connection. Moreover, the bladder docking component has a certain elasticity and can adapt to the small deformations and vibrations at the cable connection. In actual use, the cable may have small displacements or deformations due to mechanical stress, temperature change factors, etc., and the bladder docking component can dynamically adapt to these changes and always maintain a good sealing effect, thereby extending the service life of the sealing structure and reducing the maintenance frequency caused by sealing failure; 2. When replacing cables of different diameters in the present invention, when the pressing assembly is driven by the screw assembly to push the elastic air guiding assembly downward, the gas delivered into the capsule docking assembly is quantitative, and there are problems of excessive or insufficient pressing force on the cable. For a cable with a larger diameter, when the pressing force of the capsule cylinder on it exceeds the preset threshold of the pressure sensor, the pressure sensor transmits the detected pressure change signal to the controller. The controller makes a judgment according to the preset pressure threshold and issues an alarm through the alarm. At this time, the staff deflates through the valve body on the air guiding hose, so that the gas in the capsule cylinder returns to the standard volume. When replacing a cable with a smaller diameter, when the capsule cylinder does not fit the cable and the gas in it is less than the standard volume, the gas can be pushed downward by the air pushing member, and the gas is pushed into the air cylinder through the shaft tube. The gas enters the capsule cylinder along the air supply pipe and the air guiding hose, increasing the gas volume in the capsule cylinder, making the capsule cylinder fit tightly with the cable, thereby ensuring that the sealing structure can play a good sealing and fixing role for cables of different diameters, improving the versatility and reliability of the sealing structure; 3. During the process of inserting the cable core into the cylindrical metal assembly, since the cable core is usually composed of multiple strands of fine copper wires twisted together, after removing the outer insulating layer, the core wires will be in a dispersed state and lack integrity. This dispersed state makes it difficult for the core to be neatly inserted into the cylindrical metal assembly, increasing the operation difficulty. Since the elastic pressing assembly is arranged at the end of the capsule docking assembly, before the core is inserted into the cylindrical metal assembly, a pressing operation is performed on it, so that the copper wires of the core are fastened together, ensuring that the core can be quickly inserted into the cylindrical metal assembly, avoiding the problems of difficult insertion and cumbersome operation caused by the dispersion of the core wires, improving the operation convenience, saving the time and labor costs during cable maintenance and replacement, and improving the work efficiency; 4. In order to facilitate the disassembly and assembly of the cylindrical metal assembly, only need to rotate the screw assembly to drive the pressing assembly to move upward, so that the pressing assembly is far away from the cylindrical metal assembly, releasing the pressing on the cylindrical metal assembly. Then loosen the nut at the bottom of the junction box, and screw out the second screw, the conductive rod and the first screw from the junction box through the handle, so that the conductive rod disengages from the opening formed in the conductive block, releasing the limit on the conductive block. Then loosen the first bolt on the locking shaft, and the cylindrical metal assembly at the end of the capsule docking assembly can be pulled out of the junction box to achieve disassembly. When installing, operate in the reverse steps. This design enables quick and easy operation when the cylindrical metal assembly needs to be repaired, replaced or inspected, without complex tools and cumbersome steps, enhancing the flexibility and operability of maintenance, facilitating the timely discovery and handling of potential problems, and ensuring the stable operation of the power system.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0029] As Figures 1-11 shown, a wiring device for power maintenance proposed by the present invention includes a wiring box 1, an elastic air guiding assembly 4, a pressing assembly 5, and a screw rod assembly 6; Both ends of the wiring box 1 are detachably connected with bladder docking assemblies 2, and a cylindrical metal assembly 3 located inside the wiring box 1 is installed at one adjacent end of each of the two bladder docking assemblies 2, and the ends of the two cylindrical metal assemblies 3 are in contact; Both of the two elastic air guiding assemblies 4 are installed inside the wiring box 1 and are respectively communicated with the two bladder docking assemblies 2. The pressing assembly 5 is inserted on the wiring box 1 and is connected to the two elastic air guiding assemblies 4. The screw rod assembly 6 is used to drive the pressing assembly 5 to move downward to punch the cylindrical metal assembly 3, and to push the elastic air guiding assembly 4 to move downward to conduct gas into the bladder docking assembly 2; A gas pushing member 9 is installed on the elastic air guiding assembly 4.

[0030] In the present invention, the two cable cores to be connected are respectively inserted into the cylindrical metal assemblies 3 at both ends of the wiring box 1. After the cores are inserted, the screw rod assembly 6 is used to drive the pressing assembly 5 to move downward. During the downward movement of the pressing assembly 5, the cylindrical metal assembly 3 is punched. Under the punching action, the cylindrical metal assembly 3 deforms and squeezes the internal cable core, realizing firm fixation of the core. Certainly, while the pressing assembly 5 moves downward, it will push the elastic air guiding assembly 4 to move downward. The gas inside the elastic air guiding assembly 4 is squeezed and is conducted into the bladder docking assembly 2 through the channel communicated with the bladder docking assembly 2. The bladder docking assembly 2 gradually bulges under the action of the gas and tightly wraps the connection part of the cylindrical metal assembly 3 and the cable, forming a sealing structure, effectively isolating external moisture, dust, and impurities, and preventing these substances from entering the connection part and affecting power transmission and the service life of the equipment. If it is found during the sealing process that the gas volume in the bladder docking assembly 2 is insufficient, resulting in poor sealing effect, the maintenance personnel can operate the gas pushing member 9 on the elastic air guiding assembly 4 to supplement additional gas into the bladder docking assembly 2 to ensure that the bladder docking assembly 2 is tightly attached to the cable and achieve a good sealing effect.

[0031] As Figure 2 , Figure 3 , Figure 5 , and Figure 6As shown in the figure, in this embodiment, the capsule docking component 2 includes a shaft cylinder 21. Locking shafts 102 are fixed at both ends of the junction box 1. The two shaft cylinders 21 are respectively inserted into the two locking shafts 102. One adjacent end of each of the two shaft cylinders 21 extends into the junction box 1. A first bolt 103 that presses against the shaft cylinder 21 is threadedly connected to the locking shaft 102. A capsule insulation member 22 is arranged in the shaft cylinder 21.

[0032] When installing the capsule docking component 2 onto the junction box 1, the installer inserts the shaft cylinder 21 into the locking shaft 102, so that one adjacent end of the shaft cylinder 21 smoothly extends into the junction box 1. Then, the first bolt 103 threadedly connected to the locking shaft 102 is tightened. As the first bolt 103 is tightened, it gradually presses against the shaft cylinder 21, making the connection between the shaft cylinder 21 and the locking shaft 102 more stable. A capsule insulation member 22 is arranged in the shaft cylinder 21. Before the cable connection operation is carried out, the capsule insulation member 22 has been installed in the shaft cylinder 21 and is in a ready state. When the elastic air guiding component 4 guides air into the capsule docking component 2, the capsule insulation member 22 immediately bulges to press against and seal the cable.

[0033] As Figure 1 、 Figure 6 and Figure 7 shown in the figure, in this embodiment, the capsule insulation member 22 includes a capsule cylinder 221. The capsule cylinder 221 is arranged in the shaft cylinder 21. An insulating tape layer 222 is connected to the inner wall of the capsule cylinder 221; a pressure sensor 8 is arranged on the inner wall of the insulating tape layer 222. A controller 81 and an alarm 82 are installed on the junction box 1. The pressure sensor 8 and the alarm 82 are both electrically connected to the controller 81.

[0034] After the elastic air guiding component 4 conveys gas into the capsule cylinder 221, the capsule cylinder 221 bulges and contacts the cable. At this time, the capsule cylinder 221 generates a pressing force on the cable. The pressure is transmitted to the pressure sensor 8 through the insulating tape layer 222. The pressure sensor 8 converts the pressure data monitored in real time into an electrical signal and transmits it to the controller 81. A suitable pressure threshold is preset inside the controller 81. It will analyze and judge the received pressure signal. If the pressure exceeds the preset threshold, the controller 81 will immediately issue an instruction to trigger the alarm 82 to work and send an alarm to the staff.

[0035] As Figure 6 and Figure 7 shown in the figure, in this embodiment, the cylindrical metal component 3 includes a metal cylinder body 31. One adjacent end of each of the two shaft cylinders 21 is connected to the metal cylinder body 31, and the metal cylinder body 31 is communicated with the shaft cylinder 21. The two metal cylinder bodies 31 are both located in the junction box 1. Conductive blocks 32 are fixed at one adjacent end of each of the two metal cylinder bodies 31. The two conductive blocks 32 are in mutual contact. A bearing block 101 that fits against the bottoms of the two metal cylinder bodies 31 is installed in the junction box 1.

[0036] When performing cable connection operations, first insert the cable cores into the two metal cylinders 31 respectively. The metal cylinders 31 communicate with the shaft cylinder 21, providing a stable insertion space for the cable cores and having a relatively fixed position. The conductive blocks 32 at the adjacent ends of the two metal cylinders 31 are in contact with each other, ensuring good electrical connection between the two sections of cable cores. The bearing block 101 is installed inside the junction box 1 and is in close contact with the bottoms of the two metal cylinders 31. During the entire operation process, the bearing block 101 always provides stable support for the metal cylinders 31.

[0037] As Figure 2 , Figure 4 , Figure 7 , Figure 8 and Figure 9 shown, in this embodiment, the elastic air guiding assembly 4 includes air cylinders 41. The two air cylinders 41 are respectively installed at both ends inside the junction box 1 and are arranged vertically. The top ends of the air cylinders 41 extend out of the top of the junction box 1. An elastic piston member 42 connected to the pressing assembly 5 is installed inside the air cylinders 41. Air holes 44 are formed at the tops of the air cylinders 41. An air supply pipe 43 is connected to the bottom of the air cylinders 41. One end of the air supply pipe 43 away from the air cylinders 41 is connected with a first joint 431. The two first joints 431 are respectively installed at both ends of the junction box 1. A second joint 432 is detachably connected to the first joint 431. A guide air hose 433 is connected to the end of the second joint 432. The two guide air hoses 433 are respectively communicated with the two bladder cylinders 221. A valve body 434 is installed on the guide air hose 433.

[0038] When the screw assembly 6 drives the pressing assembly 5 to move downward, the pressing assembly 5 drives the connected elastic piston member 42 to move downward synchronously inside the air cylinder 41. As the elastic piston member 42 moves downward, the space inside the air cylinder 41 is compressed, and the gas is squeezed. The air holes 44 at the top of the air cylinder 41 can balance the air pressure inside and outside the air cylinder 41, ensuring that the elastic piston member 42 can slide smoothly inside the air cylinder 41. The squeezed gas flows out through the air supply pipe 43 at the bottom of the air cylinder 41, passes through the first joint 431 and the second joint 432 in sequence, and finally enters the bladder cylinder 221 through the guide air hose 433, causing the bladder cylinder 221 to bulge. During this process, if it is necessary to control the gas flow rate or stop air guiding, the valve body 434 on the guide air hose 433 can be operated to control the gas delivery. When it is necessary to maintain or replace some components of the air guiding assembly, the connection between the first joint 431 and the second joint 432 can be disassembled for operation.

[0039] As Figure 1 , Figure 9 and Figure 11As shown, in this embodiment, the elastic piston member 42 includes a first piston 421, a shaft tube 422 and a first spring 423. The first piston 421 is slidably arranged in the gas cylinder 41, and the shaft tube 422 slides through the top of the gas cylinder 41 and through the bottom end of the first piston 421. The first piston 421 is fixedly connected to the shaft tube 422, and the top of the shaft tube 422 is connected to the pressing component 5. The first spring 423 is sleeved on the shaft tube 422, and the two ends of the first spring 423 are respectively connected to the top of the gas cylinder 41 and the pressing component 5; when the pressing component 5 moves downward under the drive of the screw assembly 6 The pressing assembly 5 drives the shaft tube 422 to move downward synchronously, and the shaft tube 422 drives the first piston 421 fixedly connected thereto to slide downward in the gas cylinder 41. During the downward movement of the first piston 421 in the gas cylinder 41, the gas in the gas cylinder 41 is squeezed, so that it enters the capsule 221 through the gas supply pipe 43. In this process, the first spring 423 is compressed to store elastic potential energy. When the screw assembly 6 rotates in the opposite direction and the pressing assembly 5 moves upward, the first spring 423 releases the elastic potential energy, pushes the pressing assembly 5 to reset, and at the same time drives the shaft tube 422 and the first piston 421 back to their initial positions.

[0040] The pusher 9 includes a second piston 91, a handle 92, a sleeve 93 and a second bolt 94. The second piston 91 is slidably disposed in the shaft tube 422. The handle 92 is mounted on the second piston 91, and the top of the handle 92 slides through the top of the shaft tube 422. The sleeve 93 is sleeved on the handle 92 and connected to the pressing assembly 5. The second bolt 94 is threadedly connected to the sleeve 93 and pressed against the handle 92. A through hole 4221 is provided at the top of the shaft tube 422. When the amount of gas in the capsule 221 is insufficient and gas needs to be supplemented, first loosen the second bolt 94 to release the pressure on the handle 92, and then push the second piston 91 to slide downward in the shaft tube 422 through the handle 92. The second piston 91 squeezes the gas in the shaft tube 422 into the gas cylinder 41 through the through hole 4221 at the top. The increased gas in the gas cylinder 41 enters the capsule 221 through the air supply pipe 43 and the air guide hose 433, so that the gas volume in the capsule 221 increases and fits tightly with the cable. After the gas is supplemented, tighten the second bolt 94 to fix the handle 92 to prevent the second piston 91 from moving at will.

[0041] like Figure 2 and Figure 5 As shown, in this embodiment, the pressing assembly 5 includes a pressing plate 51 and a pressing rod 52. Two pressing rods 52 are inserted into the junction box 1, and the two pressing rods 52 are respectively located above the two metal cylinders 31. The bottom ends of the pressing rods 52 are equipped with end caps 53. The pressing plate 51 is installed on the top ends of the two pressing rods 52. The shaft tube 422 and the first spring 423 are both connected to the bottom of the pressing plate 51, the sleeve shaft 93 is connected to the top of the pressing plate 51, and the pressing plate 51 is driven downward by the screw assembly 6.

[0042] When performing the cable connection and fixing operation, rotate the handle plate 65 of the screw rod assembly 6 to rotate the first screw rod 61. Since the first screw rod 61 is threadedly connected to the pressure plate 51, as the first screw rod 61 rotates, the pressure plate 51 moves downward under the action of the thread. During the downward movement of the pressure plate 51, the two pressure rods 52 connected thereto move downward synchronously. The end heads 53 at the bottom ends of the pressure rods 52 gradually approach the metal cylinder 31. When the end heads 53 contact the metal cylinder 31, continue to apply pressure. The metal cylinder 31 deforms under the stamping action of the end heads 53, thereby squeezing and fixing the cable core inside. At the same time, the downward movement of the pressure plate 51 also pushes the shaft tube 422 and the first spring 423 downward, and then drives the first piston 421 of the elastic piston member 42 to slide downward in the air cylinder 41, realizing the function of guiding air into the bladder 221. The sleeve shaft 93 is connected to the top of the pressure plate 51, providing a basis for the installation and movement of the handle rod 92 of the air pushing member 9, facilitating the replenishment of gas through the air pushing member 9 when needed.

[0043] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, in this embodiment, the screw rod assembly 6 includes a first screw rod 61, a conductive rod 62, a second screw rod 63 and a nut 64. The first screw rod 61 threadedly passes through the top of the pressure plate 51 and the wiring box 1 and is located above the conductive block 32. Through holes 33 are provided in both of the two conductive blocks 32. The bottom end of the first screw rod 61 is connected to a conductive rod 62 passing through the conductive block 32. A through insertion channel is provided in the bearing block 101. The bottom end of the conductive rod 62 is inserted into the insertion channel. The bottom end of the conductive rod 62 is rotatably connected to a second screw rod 63. The second screw rod 63 slidably passes through the bottom of the wiring box 1. A nut 64 that presses against the bottom of the wiring box 1 is threadedly sleeved on the second screw rod 63. The top end of the first screw rod 61 is provided with a handle plate 65 located above the pressure plate 51.

[0044] When the device is in use and it is necessary to fix the cable core and seal the connection part, the operator rotates the handle disc 65, causing the first screw rod 61 to rotate around its own axis. Since the first screw rod 61 is threadedly connected to the pressure plate 51 and passes through the top of the junction box 1, as the first screw rod 61 rotates, the pressure plate 51 will move downward along the axial direction of the first screw rod 61. The conductive rod 62 connected to the bottom end of the first screw rod 61 will move downward together with the first screw rod 61. The conductive rod 62 passes through the opening 33 on the conductive block 32, providing a guiding function for the rotation and downward pressure of the first screw rod 61, and at the same time ensuring the stability of the screw assembly 6 during movement. The bottom end of the conductive rod 62 is inserted into the insertion channel of the bearing block 101, further enhancing the structural stability and preventing the first screw rod 61 from shifting during rotation. The second screw rod 63 is rotatably connected to the bottom end of the conductive rod 62 and passes through the bottom of the junction box 1. By tightening the nut 64, the second screw rod 63 is fixed to the bottom of the junction box 1, so that the entire screw assembly 6 forms a firm connection with the junction box 1; When it is necessary to disassemble or maintain the cylindrical metal component 3, first loosen the nut 64 to release the fixation of the second screw rod 63, and then rotate the handle disc 65 in the reverse direction, causing the first screw rod 61 to drive the conductive rod 62 to move upward, disengaging from the opening 33 of the conductive block 32. At the same time, the pressure plate 51 also rises, releasing the stamping on the metal cylinder body 31. At this time, it is convenient to perform subsequent disassembly, repair, or replacement operations on the cylindrical metal component 3.

[0045] As Figure 4 shown, in this embodiment, elastic pressing components 7 are installed at both ends of the two shaft cylinders 21 away from each other, and the elastic pressing components 7 are used to press the core; Figure 10 The elastic pressing component 7 includes a shaft sleeve 71. The two shaft sleeves 71 are respectively installed at both ends of the two shaft cylinders 21 away from each other. Two arc-shaped blocks 72 are symmetrically arranged inside the shaft sleeve 71. A pressing channel suitable for pressing the core is formed between the two arc-shaped blocks 72. Pressing rods 73 are installed on both sides of the two arc-shaped blocks 72 away from each other. The two pressing rods 73 respectively slide through both sides of the shaft sleeve 71. End blocks 74 are installed at both ends of the two pressing rods 73 away from each other. A second spring 75 is sleeved on the pressing rod 73, and both ends of the second spring 75 are respectively connected to the shaft sleeve 71 and the end block 74.

[0046] ​Before inserting the cable core into the metal cylinder body 31, place the cable core in the pressing channel between two arc-shaped blocks 72. At this time, the insertion of the core will squeeze the arc-shaped blocks 72, causing the arc-shaped blocks 72 to move to both sides, driving the pressing rod 73 to slide within the sleeve 71. The end block 74 on the pressing rod 73 also moves accordingly, stretching the second spring 75. The elastic force generated by the second spring 75 will prompt the arc-shaped blocks 72 to apply a reverse pressure to the core, thereby pressing the core tightly. When the insertion of the core is completed and no external force is applied to the arc-shaped blocks 72, the elastic force of the second spring 75 still maintains the pressing state of the core, ensuring that the core will not come apart during the process of being inserted into the metal cylinder body 31.

[0047] A wiring method for power maintenance, using the above-mentioned wiring equipment for power maintenance, includes the following steps: Step 1: Cut off the damaged part of the cable, and then cut off a part of the insulating sleeves at both ends of the relative cable to expose the core. Step 2: Insert the cores of the two sections of the cable into the two elastic pressing components 7 at both ends of the junction box 1 respectively, and press the cores by pressing the elastic pressing components 7 to prevent the cores from scattering. Step 3: After pressing the cores, insert the cores of the two sections of the cable through the two capsule-type docking components 2 respectively and into the corresponding metal cylinder bodies 31. Step 4: Drive the pressing component 5 to move downward by the screw component 6 to punch the metal cylinder body 31. After the metal cylinder body 31 deforms under the punching force, it squeezes the core inside it to complete the fixation of the core. Step 5: When the pressing component 5 moves downward, it can push the elastic air guiding component 4 to move downward, and conduct the gas inside it to the capsule cylinder 221, causing the capsule cylinder 221 to bulge and seal the connection between the metal cylinder body 31 and the cable. Step 6: When the capsule cylinder 221 bulges and presses against the cable, the pressure sensor 8 on the inner wall of the insulating tape layer 222 can monitor the pressing force. After the pressing force exceeds the preset threshold value of the pressure sensor 8, the pressure sensor 8 transmits the detected pressure change signal to the controller 81. The controller 81 makes a judgment according to the preset pressure threshold value and issues an alarm through the alarm 82. At this time, the staff deflates through the valve body 434 on the air guiding hose 433, so that the gas in the capsule cylinder 221 returns to the standard volume. When the capsule cylinder 221 does not fit the cable and the gas inside it is less than the standard volume, the pushing member 9 can be used to push air downward, and the gas is pushed into the air cylinder 41 through the shaft tube 422. The gas flows along the air supply pipe 43 and the air guiding hose 433 into the capsule cylinder 221 to increase the gas volume in the capsule cylinder 221 and make the capsule cylinder 221 fit tightly with the cable.

[0048] The specific working principle of the present invention is as follows: During power maintenance, the cable is pre-treated first. The damaged part is cut off and the insulating sleeve is removed to expose the battery core. The battery core is inserted into the elastic pressing assembly 7. The arc-shaped block 72 and the second spring 75 are used to press the battery core, facilitating subsequent insertion operations. Then, the battery core is inserted through the capsule docking assembly 2 into the metal cylinder 31. The handle 65 of the screw rod assembly 6 is rotated. The first screw rod 61 rotates to drive the pressing plate 51 to move downward. The end 53 of the pressing rod 52 punches the metal cylinder 31 to deform and fix the battery core. At the same time, the pressing plate 51 pushes the shaft tube 422 and the first piston 421 of the elastic air guiding assembly 4 to move downward. The gas in the air cylinder 41 enters the capsule 221 through the air supply pipe 43 and the air guiding hose 433, causing it to bulge and seal the connection between the cable and the metal cylinder 31. When the capsule 221 bulges and presses against the cable, the pressure sensor 8 monitors the pressure. If the pressure is too high, the alarm 82 alarms. The staff releases the air through the valve body 434. If the gas is insufficient, the air pushing member 9 is operated. After loosening the second bolt 94, the handle 92 is pushed, causing the second piston 91 to move downward in the shaft tube 422. The gas enters the air cylinder 41 through the through hole 4221 and is replenished into the capsule 221 to ensure the sealing effect.

Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
