Description

Technical Field

[0001] This invention relates to the field of safety protection technology for live-line work on power system distribution lines, and specifically to a temporary insulating shielding cover for live-line work using a grounding ring. Background Technology

[0002] During live-line work on 10kV distribution networks, grounding rings, as crucial interfaces for routine grounding operations, are typically located in areas frequently accessed by workers, such as pole-mounted switches, transformers, or line sections. While the grounding ring itself is not energized, its proximity to conductors and live equipment poses a significant risk. If the ring is exposed during live-line disconnection, equipment replacement, or accessory installation, it can easily lead to grounding short circuits or electric shocks due to tool contact or personnel getting too close. However, after the work is completed, the grounding ring still needs to be used as a normal grounding connection point. Therefore, it cannot be protected with long-term fixed shields or permanent insulation; temporary shielding measures are only suitable during the live-line work window.

[0003] In related technologies, insulating blankets, cable ties, or general-purpose shielding covers are commonly used on-site to temporarily cover grounding rings. However, these methods have significant drawbacks. Firstly, workers wearing multiple layers of insulating gloves have limited finger dexterity, making it inconvenient to bind, clamp, or adjust the angle of the shielding components, hindering quick and reliable installation and fixation. Secondly, most existing shielding devices lack connection interfaces compatible with insulating operating rods, preventing remote installation and retrieval from a safe distance. Manual adjustment near live parts is often necessary, increasing the risk of accidental contact with live components. Furthermore, temporary shielding components are susceptible to slippage and detachment due to wind or vibration after installation, requiring close-range manual removal during retrieval, resulting in low efficiency and poor safety. This invention proposes a new solution to address these issues. Summary of the Invention

[0004] To overcome at least one of the aforementioned drawbacks, this invention provides a temporary insulating shield for live-line work using a grounding ring. The objective of this invention can be achieved through the following technical solution: This application provides a temporary insulating shield for live-line work on a grounding ring. The temporary insulating shield includes a cover body, a limiting plate, and an operating interface. The cover body is made of insulating material to form an insulating shield on the outside of the grounding ring. The cover body has an opening at the bottom and sliding grooves on both sides. The limiting plate is disposed in the inner cavity of the cover body and has a limiting groove for limiting the insulator of the grounding ring. The operating interface is disposed on the cover body for connecting an insulating operating rod.

[0005] In one possible implementation, the chute is an open chute, comprising a straight section and a bent section, the straight section being located below the bent section and communicating with the bottom opening, the straight section being used to guide the wire of the grounding ring into the chute, and the bent section being used to limit the wire entering the chute.

[0006] In one possible implementation, the straight segment extends vertically, and the bent segment connects to the upper end of the straight segment and extends obliquely upward. The straight segment and the bent segment together form a continuous trajectory for the grounding ring to slide into and stop.

[0007] In one possible implementation, the limiting plate is disposed in the inner cavity of the cover, and the limiting groove is used for the insulator to enter the inner cavity from below and be engaged in the limiting groove. The inner wall contour of the limiting groove is adapted to the outer wall contour of the insulator. The limiting groove is used to partially cover and limit the insulator to restrict the horizontal and vertical displacement of the insulator relative to the cover.

[0008] In one possible implementation, the limiting groove and the insulator are fitted with a small gap, and a guide slope is provided at the opening of the limiting groove. The guide slope extends outward from the edge of the opening of the limiting groove and is used to guide the insulator to slide smoothly into the limiting groove.

[0009] In one possible implementation, the limiting plate is located outside the movement trajectory of the grounding ring entering the inner cavity, and the number of the limiting plates is at least two, with multiple limiting plates arranged from top to bottom, and the two limiting grooves are used to limit the insulator from the same side.

[0010] In one possible implementation, the cover includes a top wall, a front side wall, a rear side wall, a left side wall, and a right side wall. The front side wall and the rear side wall are arranged correspondingly front to back. The top wall is connected to the top of the front side wall and the top of the rear side wall. The left side wall is connected to one side of the front side wall and one side of the rear side wall. The right side wall is connected to the other side of the front side wall and the other side of the rear side wall. The sliding grooves are respectively formed on the left side wall and the right side wall. An open structure is formed at the bottom of the cover to allow the grounding ring to enter the inner cavity of the cover from below.

[0011] In one possible implementation, the left side wall and / or the right side wall are provided with a handling grip, the handling grip having a groove or handle for a hand to grip and carry the protective cover.

[0012] In one possible implementation, the cover is integrally molded from insulating material, and the cover, the limiting plate, and the operating interface constitute an integral structure.

[0013] In one possible implementation, the temporary insulating shield has a hung state and a removed state. In the hanging state, the wire is housed in the bent section, the insulator is inserted into the limiting groove, and the protective cover is suspended on the grounding ring and forms a temporary insulating shield on the outside of the grounding ring; In the removed state, the wire exits the bent section and slides out along the straight section, the insulator disengages from the limiting groove, and the protective cover separates from the grounding ring.

[0014] The beneficial technical effects of this invention are as follows: According to this disclosure, the temporary insulating shielding cover for live-line work using a grounding ring is used for hanging during live-line work. After the work is completed, it can be removed as a whole by sliding along the groove using an insulating operating rod. This satisfies the temporary shielding requirement without affecting the subsequent grounding use of the grounding ring. The cover is made of insulating material and forms an insulating shield on the outside of the grounding ring, effectively isolating the direct contact path between the worker or tools and the live parts. The bottom opening of the cover, combined with the groove, allows the cover to be hung on the line from below, eliminating the need for complex side or top connection and reducing the difficulty of alignment during long-distance operations. The groove slides with the wire, allowing the cover to slide into the predetermined position along the wire, avoiding the need for manual fine adjustments required by binding or clamping methods, improving hanging efficiency and ease of operation. The limiting groove forms a covering limit on the insulator of the grounding ring, constraining the positional relationship of the cover relative to the grounding ring, forming a stable hanging and anti-detachment effect, reducing radial detachment, slippage or deflection, and preventing displacement due to wind or vibration during operation, ensuring the stability and reliability of the temporary shielding. The operating interface allows operators to push, pull, and rotate the cover from a safe distance using an insulated operating rod. The cover remains connected to the insulated operating rod during operation, eliminating the need to locate a separate connection point when removing it, reducing the risk of loss. It also eliminates the need for close-range manual operation, significantly reducing the safety risk of accidental contact with live parts. After operation, the cover can be removed entirely using the insulated operating rod. Operators can then use the two side handles for transport and storage, improving on-site operational convenience and reducing the risk of slippage or collision damage during handling.

Therefore, they should not be construed as limitations on this invention.

[0020] This application provides a temporary insulating shield for live-line work using a grounding ring, such as... Figures 1-7As shown, the temporary insulating shield 2, applied to the grounding ring 1, includes a cover 21, a limiting plate 22, and an operating interface 23. The cover 21 is made of insulating material to form an insulating shield on the outside of the grounding ring 1. The bottom of the cover 21 is open and both sides are provided with sliding grooves 24. The limiting plate 22 is set in the inner cavity of the cover 21. The limiting plate 22 has a limiting groove 221, which is used to limit the insulator 12 of the grounding ring 1. The operating interface 23 is set on the cover 21 and is used to connect the insulating operating rod.

[0021] The temporary insulating shield for live-line work provided in this embodiment is used for hanging during live-line work. After the work is completed, it can be removed as a whole by sliding along the groove 24 using an insulating operating rod. This satisfies the temporary shielding requirement without affecting the subsequent grounding use of the grounding ring 1. The cover 21 is made of insulating material and forms an insulating shield on the outside of the grounding ring 1, which can effectively isolate the direct contact path between the worker or tools and the live parts near the grounding ring 1. The structure of the bottom opening of the cover 21, combined with the groove 24, allows the cover to be hung on the line through the lower opening, reducing the need for binding, clamping, or repeated manual adjustments. The cover can be inserted into the grounding ring 1 from below without the need for complex fitting from the side or top, reducing the difficulty of alignment during long-distance operations. The grooves 24 on both sides can form a sliding engagement with the wire 11 of the grounding ring 1, allowing the cover 21 to slide into the predetermined position along the wire 11 during the hanging process. This avoids the manual fine adjustment required by traditional binding or clamping methods, improving the hanging efficiency and operation. For ease of use, the limiting groove 221 on the limiting plate 22 limits the insulator 12 of the grounding ring 1, which can constrain the positional relationship of the cover relative to the grounding ring 1. The limiting groove 221 and the insulator 12 form a covering limiting relationship, so that the cover and the grounding ring 1 form a stable hanging and anti-detachment effect, reducing radial detachment, slippage or deflection, and preventing the cover from shifting due to wind swing or vibration during operation, ensuring the stability and reliability of the temporary shielding arrangement. The setting of the operation interface 23 allows the operator to push, pull and rotate the cover from a safe distance through the insulating operating rod. The cover and the insulating operating rod remain connected during operation, and there is no need to find a connection point when removing it, reducing the risk of loss. There is no need for close-range manual operation, which significantly reduces the safety risk of accidental contact with live parts. After the operation is completed, the cover can be removed as a whole through the insulating operating rod. The operator can hold the two sides of the carrying handle 3 for transfer, carrying and storage, improving the convenience of on-site operation and reducing the risk of slippage or collision damage during transportation.

[0022] The temporary insulating shield for live-line work using the grounding ring is detachably connected to the insulating operating rod via the rear / bottom operating interface 23. Workers can install, adjust, and remove the shield while maintaining a safe distance from live parts throughout the process. After the shield is installed, the insulating operating rod remains connected and on-site, allowing for minor adjustments during operation without needing to relocate the connection point. After completion, the shield is removed via the operating rod along the slide groove 24 and taken off the site. The entire operation requires only the insulating operating rod, eliminating the need for other auxiliary tools, simplifying the process, reducing labor intensity, and avoiding safety risks such as accidental contact with live parts and falls from heights caused by close-range manual operation. This effectively improves the safety and efficiency of live-line work.

[0023] In one possible implementation, such as Figure 1 , Figure 4 and Figure 6 As shown, the chute 24 is an open chute, which includes a straight section 241 and a bent section 242. The straight section 241 is located below the bent section 242 and is connected to the bottom opening. The straight section 241 is used to guide the wire 11 of the grounding ring 1 into the chute 24, and the bent section 242 is used to limit the wire 11 entering the chute 24.

[0024] By setting the slide groove 24 as an open groove structure and connecting it to the bottom opening, the wire 11 can directly enter the slide groove 24 from the bottom of the cover 21. The arrangement of the straight section 241 below the bending section 242 allows the wire 11 to slide upward along the straight section 241 when entering the slide groove 24. The straight section 241 plays a guiding and initial positioning role, enabling the cover to quickly find the correct installation path in the initial stage of installation. The bending section 242 limits the wire 11 entering the slide groove 24. When the wire 11 slides to the bending section 242, due to the change in path direction, the wire 11 is not easy to slide out in the opposite direction under its own weight and external force, thus achieving stable maintenance of the cover after it is installed. This structure combining the straight section 241 and the bending section 242 allows the installation process of the cover to be completed with only one continuous pushing action, without the need for additional locking or fixing operations, simplifying the on-site operation steps.

[0025] In one possible implementation, such as Figure 4 and Figure 6 As shown, the straight segment 241 extends vertically, and the bent segment 242 is connected to the upper end of the straight segment 241 and extends obliquely upward. The straight segment 241 and the bent segment 242 together form a continuous trajectory for the grounding ring 1 to slide into and stop.

[0026] The straight section 241 extends vertically, allowing the wire 11 to slide smoothly upwards after entering the groove 24, making the hanging action more natural and fluid. The bent section 242 connects to the upper end of the straight section 241 and extends diagonally upwards. This diagonally upward-extending bent section 242 forms a certain angle with the straight section 241. When the wire 11 slides to the bent section 242, the weight of the cover acts on the wire 11, generating a component force along the direction of the groove 24. This component force makes the wire 11 tend to continue sliding deeper into the bent section 242, thus forming a self-locking effect. This prevents the cover from easily coming off due to slight vibration or collision after it is hung in place. The continuous trajectory formed by the straight section 241 and the bent section 242 provides a clear path guide for the hanging of the cover. The operator only needs to push the cover along this trajectory to complete the hanging, without repeatedly adjusting the position, which greatly reduces the technical difficulty of long-distance operation.

[0027] In one possible implementation, such as Figure 5 and Figure 6 As shown, the limiting plate 22 is disposed in the inner cavity of the cover 21, and the limiting groove 221 is used to allow the insulator 12 to enter the inner cavity from below and be locked into the limiting groove 221. The inner wall contour of the limiting groove 221 is adapted to the outer wall contour of the insulator 12. The limiting groove 221 is used to form a partial covering limiting of the insulator 12 to restrict the horizontal and vertical displacement of the insulator 12 relative to the cover 21.

[0028] The limiting plate 22 is horizontally disposed in the inner cavity of the cover 21. The limiting plate 22 has a sheet-like structure, and its plate surface is approximately perpendicular to the side wall of the cover 21. A limiting groove 221 is provided on the limiting plate 22. The limiting groove 221 is a through groove structure that penetrates the upper and lower surfaces of the limiting plate 22. The projection outline of the limiting groove 221 on the horizontal plane is slightly larger than the outer outline of the horizontal cross section of the insulator 12. The opening direction of the limiting groove 221 faces forward, so that the insulator 12 can enter the inner cavity from below and move vertically upward to be inserted into the limiting groove 221.

[0029] The limiting groove 221 partially encloses and limits the insulator 12, meaning that the inner wall of the limiting groove 221 surrounds part of the outer circumference of the insulator 12. The enclosing angle of the limiting groove 221 can be slightly greater than 180°. When the insulator 12 is inserted into the limiting groove 221, the inner wall of the limiting groove 221 surrounds and abuts the insulator 12 from the left, right and rear sides. The front side of the insulator 12 is not completely covered by the limiting groove 221. This open side is used to allow the insulator 12 to enter the opening area of ​​the limiting groove 221 from the front during the installation process. Through the partially enclosed limiting structure, the limiting groove 221 can simultaneously limit the horizontal displacement of the insulator 12 relative to the cover 21, thereby forming a stable relative positional relationship between the cover and the grounding ring 1 after the cover is installed in place.

[0030] The limiting plate 22 has a clearance groove to avoid the hanging piece 13, so that the horizontal position of the limiting plate 22 in the inner cavity of the cover 21 is outside the movement trajectory of the grounding hanging ring 1 as it enters the inner cavity. That is, during the process of the grounding hanging ring 1 entering the inner cavity of the cover 21 vertically upward from below, the limiting plate 22 will not block the insulator 12. The limiting plate 22 is set approximately at the center of height relative to the front and rear side walls of the cover 21 in the horizontal direction. The opening direction of the limiting groove 221 faces the front side wall, so that after the insulator 12 enters the inner cavity from below, as the cover continues to rise, the insulator 12 gradually approaches the limiting plate 22, and when the cover is hung to the predetermined height, the insulator 12 aligns with the opening of the limiting groove 221 and is inserted into the limiting groove 221.

[0031] The bending section 242 starts from the upper end of the straight section 241 and extends in an inclined upward direction toward the limiting plate 22 inside the housing 21. When the wire 11 slides upward along the straight section 241 to the connection between the straight section 241 and the bending section 242, under the continued lifting action of the housing, the wire 11 changes its sliding direction under the guidance of the bending section 242, changing from vertical upward sliding to oblique upward sliding, and gradually moves toward the side where the limiting plate 22 is located along the extension direction of the bending section 242 until the wire 11 reaches the end of the bending section 242. At this time, the housing is in place, and the wire 11 is constrained in the bending section 242 and cannot come out on its own. This causes the housing to have a displacement tendency toward the limiting plate 22 in the horizontal direction relative to the grounding ring 1 after the wire 11 slides into the bending section 242. This displacement tendency causes the insulator 12 to move toward the limiting plate 22 and get stuck in the limiting groove 221. In other words, the bending section 242 and the limiting plate 22 cooperate with each other in spatial position. The extension direction of the bending section 242 guides the wire 11 to move the entire protective cover toward the position of the limiting plate 22, so that the insulator 12 is automatically aligned and enters the limiting groove 221 when it is hung in place, realizing the synchronous completion of hanging positioning and limiting insertion.

[0032] In one possible implementation, such as Figure 5 and Figure 6 As shown, there is a small gap between the limiting groove 221 and the insulator 12. A guide slope is provided at the opening of the limiting groove 221. The guide slope extends outward from the edge of the opening of the limiting groove 221. The guide slope is used to guide the insulator 12 to slide smoothly into the limiting groove 221.

[0033] The inner wall contour of the limiting groove 221 is adapted to the outer wall contour of the insulator 12. When the insulator 12 is inserted into the limiting groove 221, a gap fit relationship is formed between the inner wall of the limiting groove 221 and the outer wall of the insulator 12. The value of the gap is in the range of 0.5mm to 2mm, which not only ensures that the insulator 12 can smoothly enter and exit the limiting groove 221, but also forms an effective constraint on the insulator 12.

[0034] The opening of the limiting groove 221 is provided with a guide slope. The guide slope extends outward from the edge of the opening of the limiting groove 221. The guide slope is used to guide the insulator 12 to slide smoothly into the limiting groove 221 as it enters from below, and to correct the entry direction of the insulator 12. Even if there is a certain deviation in the hanging angle of the protective cover, the insulator 12 will first contact the guide slope and gradually slide into the limiting groove 221 under the guidance of the slope. This effectively reduces the alignment accuracy requirements during long-distance operation, ensures the smoothness of the removal operation, and reduces the physical exertion and operation time of the operator when operating at height.

[0035] In one possible implementation, there is one limiting plate 22, which is fixedly connected to the inner wall of the rear side wall of the cover 21.

[0036] In one possible implementation, a buffer layer may be provided on the inner wall surface of the limiting groove 221. The buffer layer is made of a flexible insulating material and is attached to the inner wall surface of the limiting groove 221. It serves to buffer the insulator 12 when it is inserted into the limiting groove 221, thereby reducing the rigid collision between the insulator 12 and the limiting groove 221. At the same time, the friction between the buffer layer and the insulator 12 is greater than the friction between the inner wall of the limiting groove 221 and the insulator 12, which helps to further prevent the insulator 12 from accidentally sliding or falling out in the limiting groove 221.

[0037] In one possible implementation, such as Figure 4 and Figure 5 As shown, the limiting plate 22 is located outside the movement trajectory of the grounding ring 1 entering the inner cavity. There are at least two limiting plates 22, and multiple limiting plates 22 are arranged from top to bottom. Two limiting grooves 221 are used to limit the insulator 12 from the same side.

[0038] The limiting plate 22 is located outside the movement trajectory of the grounding ring 1 as it enters the inner cavity, so that the grounding ring 1 will not interfere with the limiting plate 22 during the process of entering the inner cavity of the cover 21. This ensures that the cover can be smoothly fitted into the grounding ring 1 during the installation process, and avoids installation failure due to obstruction by the limiting plate 22.

[0039] The number of limiting plates 22 is at least two and they are arranged from top to bottom. Multiple limiting plates 22 can simultaneously form a limiting effect at different height positions of the insulator 12. Compared with a single limiting plate 22, this multi-point limiting method can more effectively constrain the posture of the insulator 12, prevent the insulator 12 from rotating or tilting in the limiting groove 221, and improve the stability after the protective cover is installed.

[0040] Furthermore, the limiting grooves 221 on the two limiting plates 22 limit the insulator 12 from the same side. This same-side limiting method makes the opening direction of the two limiting grooves 221 consistent. After the insulator 12 enters the inner cavity, it can be simultaneously inserted into the two limiting grooves 221. Moreover, the two limiting grooves 221 work together to form a more stable support and limiting effect for the insulator 12.

[0041] In one possible implementation, such as Figure 6 As shown, the cover 21 includes a top wall, a front side wall, a rear side wall, a left side wall, and a right side wall. The front side wall and the rear side wall are arranged in a front-to-back manner. The top wall is connected to the top of the front side wall and the top of the rear side wall. The left side wall is connected to one side of the front side wall and one side of the rear side wall. The right side wall is connected to the other side of the front side wall and the other side of the rear side wall. The sliding grooves 24 are respectively opened on the left side wall and the right side wall. An open structure is formed at the bottom of the cover 21 to allow the grounding hanging ring 1 to enter the inner cavity of the cover 21 from below.

[0042] The top wall, front side wall, rear side wall, left side wall, and right side wall together constitute the cover 21, forming a three-dimensional protective structure with five shielding surfaces. It can form insulation isolation for the grounding ring 1 and its adjacent area from five directions: top, front, rear, left, and right, effectively covering the main directions that workers may approach. The front side wall and rear side wall are set in a corresponding manner, so that the cover 21 can form shielding barriers on both the front and rear sides of the grounding ring 1 after it is installed. No matter which direction the workers operate from or which direction the tools pass by from, they can get effective insulation protection.

[0043] The left and right walls are respectively provided with grooves 24, which allow the protective cover to be guided and limited by the wires 11 on both sides during installation. The simultaneous force on both sides ensures that the protective cover remains balanced during installation and does not tilt.

[0044] The cover 21 has an open structure at the bottom, which allows the grounding ring 1 to enter the inner cavity of the cover 21 directly from below. This perfectly matches the hanging method of the cover being lifted from below, making the hanging action simple and direct, without the need to adjust the angle or direction of the cover.

[0045] In one possible implementation, such as Figures 1-6As shown, the left side wall and / or right side wall are provided with a handling grip 3, which has a groove or handle for the hand to hold and carry the protective cover.

[0046] The left and right sides are equipped with handling grips 3, allowing operators to grip the protective cover with both hands, ensuring stable handling and preventing the risk of tilting or slipping when handled with one hand. The handling grips 3 have grooves or handles for hand gripping. The grooves ensure a secure grip even when wearing gloves, while the handles provide a more reliable grip point. Both effectively prevent the cover from slipping during handling. After the work is completed, the handling grips 3 also facilitate the removal and storage of the cover, improving its convenience during transportation and storage, and reducing the possibility of damage due to slippage or collision during handling.

[0047] In one possible implementation, the cover 21 is integrally molded from insulating material, and the cover 21, the limiting plate 22, and the operating interface 23 constitute an integral structure.

[0048] The cover 21 is integrally molded from insulating material, ensuring uniform insulation performance and eliminating weak insulation areas caused by seams or joints. This guarantees reliable insulation protection in live-line working environments. The cover 21, limit plate 22, and operating interface 23 form an integrated structure, eliminating the need for assembly by operators and significantly improving efficiency and convenience. The integrated structure also eliminates the risk of loosening or detachment between components, preventing component separation due to aging or loosening of connectors during long-term use. This extends the cover's lifespan and reliability, resulting in a more compact structure, fewer parts, reduced manufacturing complexity and cost, and easier warehousing and distribution.

[0049] In one possible implementation, such as Figure 5 and Figure 6 As shown, the temporary insulating shield 2 has a hanging state and a removed state. In the hanging state, the wire 11 is housed in the bending section 242, the insulator 12 is inserted into the limiting groove 221, and the shield is suspended on the grounding ring 1, forming a temporary insulating shield outside the grounding ring 1. In the removed state, the wire 11 exits the bending section 242 and slides out along the straight section 241, the insulator 12 is removed from the limiting groove 221, and the shield is separated from the grounding ring 1.

[0050] The temporary insulating shield 2 has two working modes: a hanging state and a removed state. In the hanging state, the wire 11 is housed in the bending section 242, which limits the wire 11 so that the shield can be stably suspended on the grounding ring 1. At the same time, the insulator 12 is inserted into the limiting groove 221 to further constrain the position of the shield, ensuring that the shield can maintain the predetermined shielding posture during operation without slipping or falling off. In the removed state, the wire 11 exits the bending section 242, the insulator 12 disengages from the limiting groove 221, and the wire 11 slides out along the straight section 241. The shield is completely separated from the grounding ring 1, and the grounding ring 1 returns to its original exposed state, which can be used for subsequent grounding wire connection operations at any time. The temporary use of the shield will not affect the normal function of the grounding ring 1.

[0051] Understandably, switching between the mounted and unmounted states can be accomplished simply by pushing or pulling the insulated operating rod along the slide 24 direction, without the need for complicated unlocking or disassembly operations, which greatly simplifies the on-site use process of the protective cover.

[0052] It is understood that the grounding ring 1 includes a wire 11, an insulator 12, a hanger 13, and a fastener 14. The wire 11 is erected in an approximately horizontal direction, and the hanger 13 is suspended below the wire 11. The upper end of the hanger 13 is connected to the wire 11, and the lower end of the hanger 13 extends downward and is used to connect to the insulator 12. There are two hangers 13, which are respectively set on both sides of the insulator 12. The two hangers 13 are connected to each other by the fastener 14. The fastener 14 is used to fix the two hangers 13 relatively to the insulator 12 to ensure the reliability of the connection between the hanger 13 and the insulator 12.
