Description

Technical Field

[0001] This invention relates to the technical field of insulation covering equipment for power distribution systems, and specifically to an insulation covering device for high and low voltage busbars of an energy storage cabinet. Background Technology

[0002] Due to varying conductivity requirements, the high and low voltage busbars of energy storage cabinets differ in thickness. Existing insulation covering devices mostly use a uniform covering structure, which cannot adapt to the covering needs of busbars with different thicknesses. When using heat shrink tubing wrapping, thinner busbars are prone to loose wrapping and excessive gaps, leading to moisture and dust intrusion and a decline in insulation performance. Thicker busbars, on the other hand, may be wrapped too tightly, resulting in insulation layer cracking and peeling, compromising insulation integrity. Furthermore, manual wrapping is difficult to precisely control the wrapping force, and automated equipment lacks thickness adjustment functions, easily causing insulation layer eccentricity and damage, increasing the risk of short circuits and leakage. This fails to meet the high-voltage, high-reliability operation requirements of energy storage cabinets, and also results in low wrapping efficiency, poor yield, and high maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an insulation covering device for high and low voltage busbars in energy storage cabinets. This device is adaptable to high and low voltage busbars of varying thicknesses, preventing insulation layer eccentricity and damage, and improving the yield and efficiency of the covering process. It employs a compatible heat-shrinkable insulating tube that adheres to the surface of the busbar, effectively isolating moisture and dust, improving insulation reliability, and reducing the risk of short circuits and leakage. The device has a compact structure and strong adaptability, suitable for various high and low voltage busbars in energy storage cabinets, solving the defects caused by inconsistent thicknesses in traditional covering methods.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a base, a clamping mechanism, a heat-shrinking mechanism, and a venting mechanism; clamping mechanisms are installed at both ends of the base, and the heat-shrinking mechanism and the venting mechanism are arranged sequentially from left to right between the two clamping mechanisms; the heat-shrinking mechanism and the venting mechanism are connected by an adjustable lead screw; the heat-shrinking mechanism is movably mounted on a translation drive lead screw, which is rotatably mounted in the base, and one end of the lead screw is connected to a translation drive motor installed in the base; the bottoms of the heat-shrinking mechanism and the venting mechanism are both slidably mounted on a slide rail on the base using sliders; the clamping mechanism, the heat-shrinking mechanism, the venting mechanism, and the adjustable lead screw are all electrically connected to an electrical control box.

[0005] Furthermore, the clamping mechanism includes a clamping mechanism mounting frame. A fixed clamp is fixed to one bottom side of the clamping mechanism mounting frame using a fixed clamp mounting seat. A movable clamp is movably disposed above the fixed clamp. The movable clamp is mounted on the output end of the movable clamp screw drive. The movable clamp screw drive is fixed to the lower part of the screw drive mounting seat, which is mounted on the upper part of one side of the clamping mechanism mounting frame. Anti-slip pads are installed at both ends of the opposite surfaces of the fixed clamp and the movable clamp.

[0006] Furthermore, the heat shrinking mechanism includes a heat shrinking mechanism mounting frame. Heat shrinking duct screw drives are symmetrically installed vertically inside the mounting frame. Each heat shrinking duct screw drive has a heat shrinking duct mounting seat installed at its output end. The two ends of each heat shrinking duct mounting seat are movably positioned within vertical clearance guide grooves formed on the inner sidewall of the heat shrinking mechanism mounting frame. A heat shrinking duct is rotatably mounted on each heat shrinking duct mounting seat using a shaft seat. A flexible hose sleeve is connected through each heat shrinking duct, and the flexible hose sleeve movably passes through the heat shrinking mechanism. A heat shrink tubing mounting base is provided for installing the air supply duct and connecting lines, wherein the air supply duct is connected to the fan; an electric heating wire is coiled on the inner wall of the heat shrink tubing; several hot air nozzles are arranged opposite each other on the walls of the upper and lower heat shrink tubing, and the hot air nozzles distributed vertically are staggered; a driven gear is installed on the shaft at one end of the heat shrink tubing, and the driven gear meshes with the driving gear. The driving gear is installed at the output end of the heat shrink tubing rotation drive motor, and the heat shrink tubing rotation drive motor is installed on the heat shrink tubing mounting base.

[0007] Furthermore, the exhaust mechanism includes an exhaust mechanism mounting frame, inside which exhaust pressure roller screw drives are symmetrically installed vertically. Each exhaust pressure roller screw drive has an exhaust pressure roller mounting seat installed at its output end. The two ends of the exhaust pressure roller mounting seats are movably disposed in the upper and lower clearance guide grooves opened on the inner side wall of the exhaust mechanism mounting frame. Each exhaust pressure roller mounting seat has an exhaust pressure roller rotatably mounted on a shaft seat. A driven pulley is mounted on one end of the shaft of the exhaust pressure roller. The driven pulley is connected to the driving pulley by a transmission belt. The driving pulley is mounted on the output shaft of the exhaust pressure roller rotation drive motor, and the exhaust pressure roller rotation drive motor is mounted on the exhaust pressure roller mounting seat.

[0008] Furthermore, at the bottom of the exhaust roller mounting base, located on the left side of the exhaust roller, a scraper mounting shaft is rotatably mounted using a shaft seat. Several scrapers are mounted on the scraper mounting shaft at equal angles. The outer end face of the scraper has an arc-shaped structure and is configured to movably abut against the roller surface of the exhaust roller. One end of the scraper mounting shaft is connected to the output shaft of the scraper rotation drive motor, which is mounted on the outer wall of the shaft seat.

[0009] Furthermore, at the bottom of the exhaust roller mounting base, located on the right side of the exhaust roller, a movable shaft seat is movably connected by a built-in spring, and a secondary exhaust roller is rotatably mounted between the movable shaft seats.

[0010] Furthermore, the scraper mounting shaft is a hollow structure with several strip-shaped slots on the shaft wall. The scraper movable guide is inserted into the strip-shaped slots, and a collar is installed on the inner wall of the scraper using a spring. The collar is sleeved on the connecting shaft, which is inserted into the hollow scraper mounting shaft. Both ends are detachably connected to the two ends of the scraper mounting shaft using threads.

[0011] The working principle of this invention is as follows: After the high and low voltage busbars of the energy storage cabinet to be wrapped are horizontally inserted into the device, they are coaxially positioned and clamped by clamping mechanisms symmetrically set at both ends of the base. The fixed clamp is locked to the bottom of the clamping mechanism mounting frame by the fixed clamp mounting seat, serving as the clamping reference. The movable clamp screw drives the movable clamp to rise and fall vertically, automatically adjusting the opening and closing distance with the fixed clamp according to the actual thickness of the busbar, stably clamping both ends of the busbar, ensuring the horizontal straightness and center coaxiality of the busbar throughout the process, eliminating the problem of insulation layer eccentricity and uneven wrapping caused by busbar offset during the wrapping process, and providing a unified positioning reference for subsequent heat shrinking and degassing operations. Based on the length of the busbar to be covered and the specifications of the heat-shrinkable insulation tube, the relative distance between the heat-shrinkable mechanism and the venting mechanism on the base is adjusted by the pitch screw drive, so that the heat-shrinkable heating zone and the venting and compaction zone form a continuous working position with time matching, ensuring that the heat-shrinkable tube can immediately enter the compaction and venting process after the heat-shrinkable tube has been heated and shrunk, avoiding the bonding failure caused by the heat-shrinkable tube cooling prematurely, and adapting to the covering requirements of high and low voltage busbars of energy storage cabinets with different lengths and specifications. The symmetrically arranged upper and lower heat shrink tubing screw drives simultaneously raise and lower two sets of heat shrink tubing mounting seats along the clearance guide groove, automatically adjusting the distance between the upper and lower heat shrink tubing to maintain a uniform heating distance between the hot air nozzle and the surface of busbars of different thicknesses, adapting to the heating needs of busbars of different thicknesses; the heat shrink tubing rotation drive motor drives the heat shrink tubing to rotate circumferentially through the meshing of the drive gear and driven gear, and the fan delivers natural air from the air supply pipe into the heat shrink tubing, which is then heated by the electric heating wires on the inner wall of the heat shrink tubing. After heating, hot air is generated and simultaneously output from hot air nozzles staggered on the pipe wall. This heats the heat-shrinkable insulation tube sleeved outside the busbar evenly. Driven by a translational drive motor, the tube moves along the slide rail, causing it to shrink synchronously and evenly along the circumference and axial direction of the busbar. This completely avoids the problem of thin busbars being wrapped too loosely and thick busbars being wrapped too tightly and cracking due to uneven local heating. At the same time, the centrally symmetrical adjustment structure ensures that the heating center is completely aligned with the center of the busbar, eliminating the eccentricity defect of the insulation layer from the source. After heat shrinking, the busbar enters the working area of ​​the venting mechanism. The symmetrical upper and lower venting rollers, driven by screws, move the venting roller mounting bases synchronously up and down along the guide grooves, ensuring the distance between the upper and lower venting rollers precisely matches the thickness of the busbar and the heat-shrinked insulation layer. The venting roller rotation drive motor, through a drive pulley, transmission belt, and driven pulley, drives the venting rollers to rotate synchronously, continuously rolling and compacting the newly heat-shrinked insulation layer. This completely removes any residual air and moisture between the heat-shrinkable tube and the busbar, ensuring the insulation layer... It fits seamlessly and tightly against the surface of the busbar, without air bubbles or gaps. At the same time, the scraper rotation drive motor drives the scraper mounting shaft to rotate. The scrapers set at equal angles on the shaft continuously and elastically contact the roller surface of the exhaust pressure roller, cleaning the dust and residual adhesive from the heat shrink tubing adhering to the roller surface in real time, preventing impurities on the roller surface from causing indentations or damage to the insulation layer. The scraper adopts an elastic plug-in structure, achieving flexible contact through springs, collars, and connecting shafts, which ensures cleaning effect while avoiding rigid contact that could scratch the roller surface. It can also be quickly disassembled and replaced, reducing maintenance costs. After the insulation layer is compacted once, it enters the secondary venting roller operation area. The secondary venting roller is floatingly installed through a spring-loaded movable shaft seat, which can adapt to the slight thickness deviation of the insulation layer after heat shrinking. It performs a second flexible compaction of the insulation layer to maintain its shape, further eliminating residual micro-air bubbles and ensuring the tightness and uniformity of the wrapping throughout the process. This completely solves the industry pain points of thin busbar wrapping loosening and thick busbar insulation layer cracking and falling off. After the entire busbar section has completed the heat shrinking, venting, and shaping operations, the clamping mechanisms at both ends are released, and the insulated busbar can be removed. This achieves fully automated wrapping operations, eliminating the need for repeated manual adjustments, greatly improving wrapping efficiency and yield, ensuring the long-term reliability of the insulation wrapping of high and low voltage busbars in energy storage cabinets, and effectively reducing the safety risks of equipment short circuits and leakage.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The screw-driven lifting and adjusting structure of the clamping, heat shrinking and venting mechanism, combined with the floating secondary venting pressure roller, can accurately adapt to the wrapping requirements of busbars of different thicknesses, and completely solve the industry pain points of thin busbars being wrapped too loosely and thick busbars having cracked and fallen off the insulation layer in the traditional process. 2. The double-sided coaxial clamping and positioning, combined with the rotary and surrounding uniform heat shrinking and two-stage rolling compaction and venting, can eliminate the eccentricity of the insulation layer, achieve seamless bonding between the insulation layer and the busbar, effectively isolate moisture and dust, and avoid the risk of short circuit and leakage from the source. 3. The fully automated continuous operation eliminates the need for repeated manual parameter adjustments, significantly improving coating efficiency and yield; it features a self-cleaning roller surface structure, modular design, convenient operation and maintenance, and low operating costs, fully meeting the high reliability requirements of energy storage cabinets, and demonstrating outstanding versatility and promotional value.

[0024] See Figure 2 and Figure 3The heat shrink mechanism 3 includes a heat shrink mechanism mounting frame 3-1. Heat shrink duct screw drives 3-2 are symmetrically mounted vertically inside the heat shrink mechanism mounting frame 3-1. Each heat shrink duct screw drive 3-2 has a heat shrink duct mounting seat 3-3 mounted at its output end. The two ends of the heat shrink duct mounting seats 3-3 are movably positioned within vertical clearance guide grooves 3-1-1 formed on the inner wall of the heat shrink mechanism mounting frame 3-1. Each heat shrink duct mounting seat 3-3 has a heat shrink duct 3-4 rotatably mounted on it using a bearing. Each heat shrink duct 3-4 is connected to a high-temperature resistant silicone hose 3-9 (with an internal fiber braided layer for reinforcement; the hose sleeve 3-9 has certain deformation properties to accommodate the rotation of the heat shrink duct 3-4). The hose sleeve 3-9 is movable... A heat shrinkable duct mounting base 3-3 is provided for installing the air supply duct and connecting lines.

[0025] See Figure 4 The exhaust mechanism 4 includes an exhaust mechanism mounting frame 4-1.

[0026] See Figures 5-7The bottom of the exhaust roller mounting base 4-3, located to the left of the exhaust roller 4-4, has a scraper mounting shaft 4-10 rotatably mounted on it via a bearing seat. Three scrapers 4-11 (made of polytetrafluoroethylene (PTFE) or wear-resistant engineering plastic (POM)) are mounted at equal angles on the scraper mounting shaft 4-10. The outer end face of the scrapers 4-11 is arc-shaped and is positioned to movably abut against the roller surface of the exhaust roller 4-4. One end of the scraper mounting shaft 4-10 is connected to the output shaft of the scraper rotation drive motor 4-9, which is mounted on the outer wall of the bearing seat. The bottom of the exhaust roller mounting base 4-3... Located to the right of the exhaust pressure roller 4-4, a movable shaft seat 4-12 is movably inserted using a built-in spring. A secondary exhaust pressure roller 4-13 is rotatably installed between the movable shaft seats 4-12. The scraper mounting shaft 4-10 is a hollow structure with three strip-shaped slots on its shaft wall. The scraper 4-11 is movably guided and inserted into the strip-shaped slots. A collar 4-15 is installed on the inner wall of the scraper 4-11 using a spring 4-16. The collar 4-15 is sleeved on the connecting shaft 4-14. The connecting shaft 4-14 is inserted into the hollow scraper mounting shaft 4-10, and its two ends are detachably connected to the two ends of the scraper mounting shaft 4-10 using threads.

[0027] The working principle of this specific implementation method is as follows: After the high and low voltage busbars of the energy storage cabinet to be wrapped are horizontally inserted into the device, coaxial positioning and clamping are completed by clamping mechanisms symmetrically set at both ends of the base; the fixed clamp 2-2 is locked to the bottom of the clamping mechanism mounting frame 2-1 by the fixed clamp mounting seat 2-7 as the clamping reference; the movable clamp screw drive 2-4 drives the movable clamp 2-3 to rise and fall in the vertical direction, automatically adjusting the opening and closing distance with the fixed clamp 2-2 according to the actual thickness of the busbar, and stably clamping both ends of the busbar, ensuring the horizontal straightness and center coaxiality of the busbar throughout the process, eliminating the problem of insulation layer eccentricity and uneven wrapping caused by busbar offset during the wrapping process, and providing a unified positioning reference for subsequent heat shrinking and degassing operations; According to the length of the busbar to be covered and the specifications of the heat shrinkable insulation tube, the relative distance between the heat shrinking mechanism 3 and the exhaust mechanism 4 on the base 1 is adjusted by the pitch screw drive 5, so that the heat shrinking heating zone and the exhaust compaction zone form a continuous working position with time matching, ensuring that the heat shrinkable tube can immediately enter the compaction and exhaust process after the heat shrinkable tube is heated and shrunk, avoiding the bonding failure caused by the heat shrinkable tube cooling prematurely, and adapting to the covering requirements of high and low voltage busbars of energy storage cabinets with different lengths and specifications. The symmetrically arranged upper and lower heat shrink tubing screw drives 3-2 drive two sets of heat shrink tubing mounting seats 3-3 to rise and fall synchronously along the clearance guide groove 3-1-1, automatically adjusting the distance between the upper and lower heat shrink tubing 3-4 so that the hot air nozzle 3-8 maintains a uniform heating distance with the surface of busbars of different thicknesses, adapting to the heating needs of busbars of different thicknesses; the heat shrink tubing rotation drive motor 3-5 drives the heat shrink tubing 3-4 to rotate circumferentially through the meshing of the drive gear 3-6 and the driven gear 3-7, and the fan delivers natural air from the air supply pipe into the heat shrink tubing 3-4, which then... The electric heating wire on the inner wall of the heat shrink tubing 3-4 heats up to generate hot air, which is then simultaneously output by the hot air nozzles 3-8 staggered on the tubing wall. This hot air uniformly heats the heat shrink insulation tubing sleeved outside the busbar. Driven by the translation drive motor 8, the tubing moves along the slide rail 6, causing it to shrink uniformly and synchronously along the circumference and axial direction of the busbar. This completely avoids the problem of uneven heating in certain areas, which can cause thin busbars to be wrapped too loosely or thick busbars to be wrapped too tightly and crack. At the same time, the centrally symmetrical adjustment structure ensures that the heating center is completely aligned with the center of the busbar, eliminating the eccentricity defect of the insulation layer from the source. After heat shrinking, the busbar enters the working area of ​​the venting mechanism 4. The symmetrical upper and lower venting roller screw drive 4-2 drives the venting roller mounting base 4-3 to rise and fall synchronously along the clearance guide groove 4-1-1, so that the distance between the upper and lower venting rollers 4-4 is precisely matched with the thickness of the busbar and the heat-shrinked insulation layer. The venting roller rotation drive motor 4-5 drives the venting rollers 4-4 to rotate synchronously through the drive pulley 4-6, transmission belt 4-7 and driven pulley 4-8, continuously rolling and compacting the insulation layer that has just been heat-shrinked, completely expelling the air and moisture remaining between the heat-shrink tube and the busbar, ensuring the insulation layer... It fits seamlessly and tightly against the surface of the busbar, without air bubbles or gaps. At the same time, the scraper rotation drive motor 4-9 drives the scraper mounting shaft 4-10 to rotate. The scrapers 4-11, which are set at equal angles on the shaft, continuously and elastically contact the roller surface of the exhaust pressure roller 4-4, cleaning the dust and residual adhesive of the heat shrink tubing adhering to the roller surface in real time, and avoiding the insulation layer from being indented or damaged by impurities on the roller surface. The scraper 4-11 adopts an elastic plug-in structure, which achieves flexible contact with the connecting shaft 4-14 through the spring 4-16, the collar 4-15, and the spring spring 4-16. This ensures the cleaning effect while avoiding rigid contact that could scratch the roller surface. It can also be quickly disassembled and replaced, reducing maintenance costs. After the insulation layer is compacted once, it enters the working area of ​​the secondary venting roller 4-13. The secondary venting roller 4-13 is floatingly installed through the spring-loaded movable shaft seat 4-12. It can adapt to the slight thickness deviation of the insulation layer after heat shrinking, and perform secondary flexible compaction and shaping of the insulation layer to further eliminate residual micro air bubbles. This ensures the tightness and uniformity of the fit throughout the wrapping process, and completely solves the industry pain points of thin busbar wrapping loosening and thick busbar insulation layer cracking and falling off. After the entire busbar section has completed the heat shrinking, venting and shaping operations, the clamping mechanisms 2 at both ends are released, and the insulated busbar can be removed. This realizes the fully automated wrapping operation, eliminating the need for repeated manual adjustments, greatly improving wrapping efficiency and yield, ensuring the long-term reliability of the insulation wrapping of the high and low voltage busbars of the energy storage cabinet, and effectively reducing the safety risks of equipment short circuits and leakage.

[0028] Compared with the prior art, the beneficial effects of the present invention are: 1. The screw-driven lifting and adjusting structure of the clamping, heat shrinking and venting mechanism, combined with the floating secondary venting pressure roller, can accurately adapt to the wrapping requirements of busbars of different thicknesses, and completely solve the industry pain points of thin busbars being wrapped too loosely and thick busbars having cracked and fallen off the insulation layer in the traditional process. 2. The double-sided coaxial clamping and positioning, combined with the rotary and surrounding uniform heat shrinking and two-stage rolling compaction and venting, can eliminate the eccentricity of the insulation layer, achieve seamless bonding between the insulation layer and the busbar, effectively isolate moisture and dust, and avoid the risk of short circuit and leakage from the source. 3. The fully automated continuous operation eliminates the need for repeated manual parameter adjustments, significantly improving coating efficiency and yield; it features a self-cleaning roller surface structure, modular design, convenient operation and maintenance, and low operating costs, fully meeting the high reliability requirements of energy storage cabinets, and demonstrating outstanding versatility and promotional value.

[0029] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.

8. The insulation covering device for high and low voltage busbars of an energy storage cabinet according to claim 7, characterized in that: Its working principle is as follows: After the high and low voltage busbars of the energy storage cabinet to be wrapped are horizontally inserted into the device, coaxial positioning and clamping are completed by clamping mechanisms symmetrically set at both ends of the base; the fixed clamp (2-2) is locked at the bottom of the clamping mechanism mounting frame (2-1) by the fixed clamp mounting seat (2-7) as the clamping reference; the movable clamp screw drive (2-4) drives the movable clamp (2-3) to rise and fall in the vertical direction, and automatically adjusts the opening and closing distance with the fixed clamp (2-2) according to the actual thickness of the busbar, so as to stably clamp both ends of the busbar, ensuring the horizontal straightness and center coaxiality of the busbar throughout the process, eliminating the problem of insulation layer eccentricity and uneven wrapping caused by busbar offset during the wrapping process, and providing a unified positioning reference for subsequent heat shrinking and degassing operations; According to the length of the busbar to be covered and the specifications of the heat shrink insulation tube, the relative distance between the heat shrink mechanism (3) and the exhaust mechanism (4) on the base (1) is adjusted by the adjusting screw drive (5) so that the heat shrink heating zone and the exhaust compaction zone form a continuous working station with time matching, ensuring that the heat shrink tube can immediately enter the compaction and exhaust process after the heat shrink tube has finished heating and shrinking, avoiding the bonding failure caused by the heat shrink tube cooling in advance, and adapting to the high and low voltage busbar covering requirements of energy storage cabinets with different length specifications; The symmetrically arranged upper and lower heat shrink tubing screw drives (3-2) drive two sets of heat shrink tubing mounting seats (3-3) to rise and fall synchronously along the clearance guide groove (3-1-1), automatically adjusting the distance between the upper and lower heat shrink tubing (3-4) to maintain a uniform heating distance between the hot air nozzle (3-8) and the surface of busbars of different thicknesses, adapting to the heating needs of busbars of different thicknesses; the heat shrink tubing rotation drive motor (3-5) drives the heat shrink tubing (3-4) to rotate circumferentially through the meshing of the drive gear (3-6) and the driven gear (3-7), and the fan delivers natural air from the air supply pipe to the heat shrink tubing (3-4). 4) Inside, the electric heating wire on the inner wall of the heat shrink tubing (3-4) heats up the air to form hot air, which is then output synchronously by the hot air nozzles (3-8) staggered on the tubing wall. This heats up the heat shrink insulation tube that is sleeved outside the busbar evenly, and moves along the slide rail (6) under the drive of the translation drive motor (8), so that the heat shrink tube shrinks synchronously and evenly along the circumference and axial direction of the busbar. This completely avoids the problem of thin busbars being wrapped too loosely and thick busbars being wrapped too tightly and cracking due to uneven local heating. At the same time, through the centrally symmetrical adjustment structure, the heating center is ensured to be completely aligned with the center of the busbar, thus eliminating the eccentricity defect of the insulation layer from the source. After the busbar has completed heat shrinking, it enters the working area of ​​the venting mechanism (4). The upper and lower symmetrical venting roller screw drive (4-2) drives the venting roller mounting seat (4-3) to rise and fall synchronously along the relief guide groove (4-1-1), so that the distance between the upper and lower venting rollers (4-4) is precisely matched with the thickness of the busbar and the heat-shrinked insulation layer. The venting roller rotation drive motor (4-5) drives the venting roller (4-4) to rotate synchronously through the drive pulley (4-6), transmission belt (4-7) and driven pulley (4-8), continuously rolling and compacting the insulation layer that has just completed heat shrinking, completely expelling the air and moisture remaining between the heat shrink tube and the busbar, and ensuring the insulation. The insulation layer is seamlessly and tightly bonded to the surface of the busbar, without air bubbles or gaps. At the same time, the scraper rotation drive motor (4-9) drives the scraper mounting shaft (4-10) to rotate. The scrapers (4-11) set at equal angles on the shaft continuously and elastically contact the roller surface of the exhaust pressure roller (4-4), cleaning the dust and residual adhesive of the heat shrink tubing adhering to the roller surface in real time, avoiding impurities on the roller surface from causing indentations or damage to the insulation layer. The scraper (4-11) adopts an elastic plug-in structure, and achieves flexible contact through spring (4-16), collar (4-15) and connecting shaft (4-14), which not only ensures the cleaning effect, but also avoids rigid contact that scratches the roller surface. At the same time, it can be quickly disassembled and replaced, reducing maintenance costs. After the insulation layer is compacted once, it enters the secondary venting roller (4-13) working area. The secondary venting roller (4-13) is installed in a floating manner through the movable shaft seat (4-12) with spring. It can adapt to the slight thickness deviation of the insulation layer after heat shrinking, and perform secondary flexible compaction and shape preservation of the insulation layer. It further eliminates residual micro air bubbles, ensures the tightness of the fit and the uniformity of the thickness throughout the wrapping process, and completely solves the industry pain points of thin busbar wrapping loosening and thick busbar insulation layer cracking and falling off. After the entire busbar section has completed heat shrinking, venting and shape preservation operations, the clamping mechanism (2) at both ends is released, and the busbar with insulation wrapping can be removed. It realizes the fully automated wrapping operation, without the need for repeated manual adjustment, greatly improves the wrapping efficiency and yield, ensures the long-term reliability of the insulation wrapping of high and low voltage busbars of the energy storage cabinet, and effectively reduces the safety risks of equipment short circuit and leakage.
