Description

Technical Field

[0001] This invention relates to the field of insulating sleeve processing technology, specifically a magnetic insulating sleeve and its processing technology. Background Technology

[0002] In power distribution systems, insulating sheaths are core components that protect the incoming and outgoing terminals of equipment such as surge arresters, pole-mounted circuit breakers, fuses, and connecting fittings. They can effectively prevent short circuits, leakage currents, and equipment corrosion accidents caused by small animals touching the equipment, foreign objects touching it, or rainwater erosion. They are important protective devices to ensure the safe and stable operation of the power grid.

[0003] Currently, most mainstream insulating sleeves on the market adopt snap-on or binding fixing structures, which have many drawbacks in practical applications: First, the installation efficiency is low and the safety risk is high. Traditional structures require special tools to snap on or bind with straps, making it difficult and time-consuming to operate during live work. It is difficult for a single person to complete the work independently, which greatly increases the risk of electric shock to maintenance personnel. Second, the fixing reliability is poor. Plastic snaps are prone to aging and cracking when exposed to the outdoor environment for a long time. The binding straps are prone to loosening and falling off due to temperature changes and wind, resulting in protection failure and causing power safety accidents. Third, there are shortcomings in the processing technology. The newly added magnetic protrusions and magnetic holes of magnetic sleeves have a small space and delicate structure, which is difficult to clean thoroughly by hand. Residual burrs will directly cause the magnets to be unable to be assembled or to be assembled loosely. Moreover, the poor consistency of manual operation can easily scratch the product surface, affecting the insulation performance and appearance quality.

[0004] Based on this, a magnetic insulating sheath and its processing technology are now provided, which can eliminate the existing drawbacks. Summary of the Invention

[0005] The purpose of this invention is to provide a magnetic insulating sheath and its processing technology to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A magnetic insulating sheath includes a sheath shell, a cable sheath, a U-shaped plate, and magnetic protrusions. The sheath shell corresponds to the shape of a surge arrester. The sheath shell, cable sheath, U-shaped plate, and magnetic protrusions are integrally molded. The cable sheath has edges. The magnetic protrusions are located on the side walls of two U-shaped plates. Magnetic holes are formed on the side walls of the magnetic protrusions. Magnets are glued into the magnetic holes of the magnetic protrusions with waterproof adhesive, and two opposing magnets attract each other.

[0007] The processing technology of the magnetic insulating sheath includes the following steps: S1: Silicone raw rubber, reinforcing agent, structure control agent, vulcanizing agent and various functional additives are put into the mixing equipment according to the ratio. Through repeated kneading and mixing, the various additives are evenly dispersed in the silicone rubber to form the final compound for molding. S2: The mixed rubber compound is further thinned and rolled on a two-roll mill to plasticize and soften it, achieving the required softness and thickness for compression molding. The treated rubber compound is then cut into blanks of specific weight and shape for later use. S3: Place the cut rubber blank into the preheated metal mold cavity. After the mold is closed, vulcanize under high temperature and high pressure. The pressure makes the rubber fill every corner of the mold, and the high temperature triggers the vulcanization reaction, causing the linear silicone rubber molecular chains to cross-link into a three-dimensional network structure, changing from plastic to elastomer. S4: Place the molded and pre-trimmed protective cover into an oven and bake at a constant temperature of 200℃ for several hours; S5: After the product has cooled, use a flash removal device to remove the flash generated during molding; S6: Insert the magnet into the hole of the magnetic protrusion, and note that the magnets on both sides are magnetically attracted to each other. Finally, conduct strict spot checks on appearance, size and electrical performance. Only after passing the checks can the magnet be packaged and put into storage.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The magnetic insulating cover of this invention is easy to install, and a single person can quickly complete the live installation within minutes.

The innovative magnetic insulating cover achieves stable and strong adsorption force through high-performance permanent magnets.

The ingenious design of the support plate, narrow at the beginning and wide at the end, not only provides internal support by opening the U-shaped plate during descent but also performs secondary correction of the insulation sheath, ensuring precise alignment between the scraper and the deflash. Simultaneously, the adjustable angle of the clamping plate adapts to the slope of the cable sheath, resulting in more stable and reliable clamping. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-11 As shown, a magnetic insulating sheath includes a sheath shell 41, a cable sheath 42, a U-shaped plate 43, and a magnetic protrusion 44. The sheath shell 41 corresponds to the shape of the surge arrester. The sheath shell 41, the cable sheath 42, the U-shaped plate 43, and the magnetic protrusion 44 are integrally molded. The cable sheath 42 is provided with edges. The magnetic protrusion 44 is provided on the side walls of the two U-shaped plates 43. Magnetic holes are opened on the side walls of the magnetic protrusion 44. Magnets 45 are glued to the magnetic holes of the magnetic protrusion 44 with waterproof adhesive. The two opposing magnets 45 attract each other.

[0034] The magnetic insulating cover is easy to install, and a single person can quickly complete the live installation in minutes. It requires no complicated procedures, is simple to use, greatly saves installation time, and improves the efficiency of live work. It is an invaluable and efficient installation solution for the power industry.

[0035] The innovative magnetic insulating cover achieves stable and strong adsorption force through high-performance permanent magnets. Combined with the embedded magnet structure, it ensures a firm and reliable installation. It can be widely used in situations where insulating covers need to be installed on the incoming and outgoing terminals of circuit breakers, fuses, and connecting hardware on power distribution lines.

[0036] The processing technology of magnetic insulating sleeve includes the following steps: S1: Silicone raw rubber, reinforcing agent, structure control agent, vulcanizing agent and various functional additives are put into the mixing equipment according to the ratio. Through repeated kneading and mixing, the various additives are evenly dispersed in the silicone rubber to form the final compound for molding. S2: The mixed rubber compound is further thinned and rolled on a two-roll mill to plasticize and soften it, achieving the required softness and thickness for compression molding. The treated rubber compound is then cut into blanks of specific weight and shape for later use. S3: Place the cut rubber blank into the preheated metal mold cavity. After the mold is closed, vulcanize under high temperature and high pressure. The pressure makes the rubber fill every corner of the mold, and the high temperature triggers the vulcanization reaction, causing the linear silicone rubber molecular chains to cross-link into a three-dimensional network structure, changing from plastic to elastomer. S4: Place the molded and pre-trimmed protective cover into an oven and bake at a constant temperature of 200℃ for several hours; S5: After the product has cooled, use a flash removal device to remove the flash generated during molding; S6: Insert magnet 45 into the hole of magnetic protrusion 44. Note that magnets 45 on both sides are magnetically attracted to each other. Finally, conduct strict spot checks on appearance, size and electrical performance. Only after passing the checks can the product be packaged and put into storage.

[0037] A flash removal device includes a positioning module 1 and a flash removal module 2. The positioning module 1 is used to initially limit the position of the insulating sheath to be processed. The positioning module 1 includes a positioning platform 3, a positioning ring 4, a scraper 5, and a limiting post 10. The positioning ring 4 is fixedly connected to the upper surface of the positioning platform 3. The positioning ring 4 is fixedly connected to the limiting post 10. The positioning ring 4 is a circular ring that matches the shape of the sheath shell 41. The scraper 5 is installed on the upper surface of the positioning platform 3. The scraper 5 abuts against the concave surface of the U-shaped plate 43. Positioning ring 4, limiting post 10, and scraper 5 work together to limit the range of motion of the insulating sheath to be processed.

[0038] The flash removal module 2 is used to remove flash from the insulating sheath to be processed.

[0039] In one embodiment, the deflash removal module 2 includes a deflash removal component one for deflash removal of the concave surface of the support plate 12, a deflash removal component two for deflash removal of the magnet 45, a support component for supporting the two U-shaped plates 43, a stabilizing component one for stabilizing and limiting the two sides of the cable sheath 42, and a stabilizing component two for stabilizing and limiting the top of the sheath shell 41. The deflash removal assembly includes a push plate 14, an assembly plate 15, a processing table 16, an electric push rod 17, and an assembly frame 47. The electric push rod 17 is mounted on the upper surface of the processing table 16. The output end of the electric push rod 17 is fixedly connected to the assembly plate 15 through the assembly frame 47. The push plate 14 is fixedly mounted on the side wall of the electric push rod 18 by bolts. The upper surface of the positioning table 3 is provided with a guide rail 6. The scraper 5 is slidably connected to the inner wall of the guide rail 6. The lower surface of the scraper 5 is fixedly connected with a slider 7. The lower surface of the positioning table 3 is fixedly connected with a fixing plate 8. A spring is fixedly connected between the slider 7 and the fixing plate 8. A sliding rod 9 is fixedly connected to the side wall of slider 7, and the sliding rod 9 is slidably connected to the fixed plate 8 through it.

[0040] Place the insulating sheath into the positioning ring 4, and place the concave part of the U-shaped plate 43 onto the scraper 5. During the placement process, the scraper 5 needs to be pulled. The scraper 5 has a concave structure, so that the scraper 5 abuts against the side wall of the concave hole of the U-shaped plate 43, and under the action of the spring, the scraper 5 is pulled backward to initially correct the position of the insulating sheath, so that the opening of the insulating sheath cable sheath 42 is kept as close as possible to the same vertical plane as the support plate 12, and quickly complete the initial limiting of the insulating sheath. The electric actuator 17 is activated by external control. The electric actuator 17 moves the assembly plate 15 closer to the insulating sheath. The assembly plate 15 moves the support plate 12 until the support plate 12 is fully inserted into the cable sheath 42. During this process, the assembly plate 15 will move the push plate 14 to abut against the slider 7. The slider 7 moves the scraper 5. The scraper 5 scrapes off the burrs at the recess of the U-shaped plate 43 until the scraper 5 moves to the other side of the recess of the U-shaped plate 43 and abuts against the other side to continue to limit the insulating sheath.

[0041] In one embodiment, the deburring component 2 includes a convergence frame 13, a scraper 2 39, and a mounting plate 40. The side wall of the mounting plate 15 is fixedly connected to two symmetrical guide rails 4 29, and the side wall of the mounting plate 15 is fixedly connected to a guide rail 25. The inner wall of the guide rail 25 is slidably connected to a slider 26, and the inner wall of the guide rail 4 29 is slidably connected to a slider 4 30. The slider 26 is fixedly connected to a mounting plate 24 via a fixed shaft, and the slider 4 30 is fixedly connected to a mounting plate 5 48 via a fixed shaft. The fixed shaft connected to the slider 26 and the fixed shaft connected to the slider 4 30 are rotatably coupled with a connecting rod 49. The side wall of the mounting plate 5 48 is bolted to the convergence frame 13, and the side wall of the convergence frame 13 is fixedly connected to the mounting plate 40. The side wall of the mounting plate 40 is equipped with four scrapers 2 39 driven by a motor to rotate. The positions of the scrapers 2 39 correspond to the magnetic holes of the magnetic protrusions 44. An electric actuator 18 is fixedly connected to the side wall of the assembly plate 15. The output end of the electric actuator 18 is fixedly connected to the mounting plate 24 via the connecting plate 22. The side wall of the assembly plate 15 has holes for the connecting plate 22 to move.

[0042] In one embodiment, the support assembly includes a support plate 12. The support plate 12 is bolted to the side wall of the mounting plate 24. The cross section of the support plate 12 is a structure that goes from narrow to wide and then back to narrow. The support plate 12 has a recessed hole corresponding to the U-shaped plate 43. The cross-sectional length of the support plate 12 is less than the opening width of the cable sheath 42.

[0043] The electric actuator 18 is activated by an external controller. The electric actuator 18 drives the mounting plate 24 to descend via the connecting plate 22. The mounting plate 24 drives the support plate 12 to descend. The support plate 12 has a cross-section that is narrow at first, then wide, and then narrow again. This structure can smoothly spread the two U-shaped plates 43 in a small range, providing effective support for the subsequent rotation of the scraper 39 to remove burrs. This prevents the U-shaped plates 43 from bending inward during the scraper 39's burr removal process, which would affect the burr removal effect on the magnetic holes of the magnetic protrusion 44. Furthermore, the support plate 12 can further correct the insulation sleeve during its descent, so that the two U-shaped plates 43 are positioned between the two mounting plates 40, allowing the scraper 39 to smoothly enter the magnetic holes of the magnetic protrusion 44.

[0044] In one embodiment, the stabilizing component 1 includes a lower pressure plate 20, a guide rod 21, and a mounting plate 1 23. A guide rail 3 27 is fixedly connected to the side wall of the mounting plate 15. A slider 3 28 is slidably connected to the inner wall of the guide rail 3 27. The mounting plate 1 23 is fixedly connected to the slider 3 28. A lower pressure frame 19 is installed on the mounting plate 1 23 by bolts. The lower pressure plate 20 is fixedly connected to the lower surface of the lower pressure frame 19 by springs. The mounting plate 1 23 and the mounting plate 2 24 are fixedly connected by bolts. A guide rod 21 is fixedly connected to the upper surface of the lower pressure plate 20, and the guide rod 21 is slidably connected to the lower pressure frame 19.

[0045] As the electric actuator 18 lowers the mounting plate 24, it also lowers the mounting plate 23. The mounting plate 23 then lowers the pressure plate 20. The pressure plate 20, in conjunction with the spring, limits the top of the insulating sleeve, reducing the amplitude of the vertical vibration of the insulating sleeve during the deburring process of the scraper 39. This makes the insulating sleeve more stable and improves the deburring quality of the scraper 39.

[0046] In one embodiment, the stabilizing component 2 includes a slider 32, a mounting plate 33, a clamping frame 34, and a clamping plate 36. Two symmetrical guide rails 31 are fixedly connected to the side wall of the mounting plate 15. The slider 32 is slidably connected to the inner wall of the guide rails 31. The mounting plate 33 is fixedly connected to the side wall of the slider 32. The clamping frame 34 is fixedly connected to the mounting plate 33 by bolts. A sliding plate 35 is slidably connected to the side wall of the clamping frame 34. The clamping plate 36 is rotatably mounted on the side wall of the sliding plate 35. The clamping plate 36 is locked to rotate by bolts with the sliding plate 35. A fixing plate 37 is fixedly connected to the side wall of the clamping frame 34. The fixing plate 37 is fixed to the sliding plate 35 by bolts. The clamping plate 36 can rotate to adapt to the inclined surface of the cable sheath 42. The clamping frame 34 is fixedly connected to the approach frame 13 by a fixing post.

[0047] Mounting plate 24, through two connecting rods 49, drives two mounting plates 48 to move closer to the center, while simultaneously driving two clamping frames 34 to move closer to the center, so that clamping plate 36 abuts against the side wall of cable sheath 42, providing more stable lateral positioning of the cable sheath 42 of the magnetic sheath, effectively reducing the lateral swaying amplitude of the insulating sheath during the deburring process of scraper 2 39.

[0048] In one embodiment, two symmetrical sliding plates 46 are fixedly connected to the side wall of the assembly frame 47, and two symmetrical drive rails 11 are fixedly connected to the upper surface of the processing table 16. The sliding plates 46 are slidably connected to the inner wall of the drive rails 11.

[0049] In one embodiment, a battery compartment 38 is provided on the side wall of the converging frame 13. The battery compartment 38 contains a mobile power supply, and the motor that drives the scraper 2 39 to rotate is electrically connected to the mobile power supply.

[0050] The above embodiments disclose a flash removal device, the specific working principle and process of which are as follows: S1: Place the insulating sheath into the positioning ring 4, and place the concave part of the U-shaped plate 43 onto the scraper 5. During the placement process, the scraper 5 needs to be pulled. The scraper 5 has a concave structure, so that the scraper 5 abuts against the side wall of the concave hole of the U-shaped plate 43, and under the action of the spring, the scraper 5 is pulled backward to initially correct the position of the insulating sheath, so that the opening of the insulating sheath cable sheath 42 is kept as close as possible to the same vertical plane as the support plate 12, quickly completing the initial limiting of the insulating sheath. At the same time as correcting the position, the scraper 5 can also remove the burrs from the concave part of the U-shaped plate 43. S2: The electric push rod 17 is started by external control. The electric push rod 17 drives the assembly plate 15 to move closer to the insulating sheath. The assembly plate 15 drives the support plate 12 to move until the support plate 12 is fully inserted into the cable sheath 42. During this process, the assembly plate 15 will drive the push plate 14 to abut against the slider 7. The slider 7 drives the scraper 5 to move. The scraper 5 scrapes off the burrs at the concave hole of the U-shaped plate 43 until the scraper 5 moves to the other side of the concave hole of the U-shaped plate 43 and abuts against the other side to continue to limit the insulating sheath. S3: The electric actuator 18 is activated by the external controller. The electric actuator 18 drives the mounting plate 24 to descend via the connecting plate 22. The mounting plate 24 drives the support plate 12 to descend. The support plate 12 has a cross-section that is narrow at first, then wide, and then narrow again. This structure can smoothly spread the two U-shaped plates 43 in a small range, providing effective support for the subsequent rotation of the scraper 39 to remove burrs. This prevents the U-shaped plates 43 from bending inward during the scraper 39's burr removal process, which would affect the burr removal effect on the magnetic holes of the magnetic protrusion 44. Furthermore, the support plate 12 can further correct the insulation sleeve during its descent, so that the two U-shaped plates 43 are located in the middle of the two mounting plates 40, allowing the scraper 39 to smoothly enter the magnetic holes of the magnetic protrusion 44.

[0051] S4: While the electric push rod 18 drives the mounting plate 24 to descend through the connecting plate 22, the mounting plate 24 drives the two mounting plates 48 to move towards the middle through the two connecting rods 49. The two mounting plates 48 drive the approaching frame 13 and the mounting plate 40 to move towards the middle, so that the scraper 39 can smoothly enter the magnetic hole of the magnetic protrusion 44. S4: When the electric push rod 218 drives the mounting plate 224 to descend, it also drives the mounting plate 123 to descend. The mounting plate 123 drives the lower pressure plate 20 to descend. The lower pressure plate 20, in conjunction with the spring, limits the top of the insulating sleeve, reducing the amplitude of the up-and-down vibration of the insulating sleeve during the deburring process of the scraper 239. The insulating sleeve is fixed more stably, improving the deburring quality of the scraper 239. S5: Mounting plate 24 drives two mounting plates 5 48 to move closer to the center through two connecting rods 49, and at the same time drives two clamping frames 34 to move closer to the center, so that the clamping plate 36 abuts against the side wall of the cable sheath 42, and provides more stable lateral limit for the position of the magnetic cable sheath 42, effectively reducing the lateral sway amplitude of the insulating sheath during the deburring process of scraper 2 39. S6: The drive motor of scraper 2 39 is started by the controller. Scraper 2 39 rotates to grind the magnetic hole of magnetic protrusion 44 to remove the flash, so as to avoid the flash in the magnetic hole causing the magnet 45 to be unable to be installed into the magnetic hole smoothly. S7: After polishing, start electric push rod 2 18 and electric push rod 1 17 to disengage the deburring module 2 from the magnetic sleeve. The scraper 1 5 will be reset under the action of the spring. Finally, the magnetic insulating sleeve with the deburred edge removed can be taken out directly from the positioning ring 4.
