Description

Technical Field

[0001] This application relates to the field of power equipment maintenance technology, specifically a rapid isolation device for emergency repair of power grid line faults. Background Technology

[0002] In power emergency repair operations, isolation fences are key equipment for ensuring on-site safety and quickly demarcating work areas. In the prior art, utility model patent CN215407858U provides a foldable isolation fence for power emergency repairs. This design achieves the folding and retraction of the protective frame through the rotation of connecting columns, uses connecting straps for securing it, and incorporates movable legs for easy overall transport. During assembly, adjacent frames are quickly connected using rubber open rings and clips, and stable fixation is achieved by inserting folded positioning pins into the ground. The fence height can also be flexibly adjusted using adjusting rods and elastic blocks.

[0003] The above design improves the efficiency of disassembly and assembly and environmental adaptability of the isolation fence to a certain extent, and solves the problems of time-consuming on-site assembly and inconvenient transportation of traditional fences. However, since the protective frame, connecting posts and other components are mostly made of metal or have a heavy structure, the overall weight is large, and even after being folded, it still requires the cooperation of multiple people or auxiliary tools to move.

[0004] Therefore, this application provides a rapid isolation device for emergency repair of power grid line faults to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a rapid isolation device for emergency repair of power grid line faults, aiming to solve the problems of existing power emergency repair isolation devices mentioned in the background art, such as bulky structure, inconvenient transportation, and low assembly efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a rapid isolation device for emergency repair of power grid line faults, comprising a fixed sleeve with a folding support foot at the bottom; a through opening on the fixed sleeve, a rotating rod rotatably mounted inside the fixed sleeve, an isolation mesh cloth wound on the rotating rod, and one end of the isolation mesh cloth passing through the opening and extending to the outside of the fixed sleeve; through the storage structure design of the folding support foot and the wound isolation mesh cloth, the storage volume of the device is greatly reduced, and with the quick-connect structure of the first C-shaped retaining ring and the locking rod, tool-free convenient handling and rapid on-site assembly are achieved, effectively improving the efficiency of power emergency repair isolation operations.

[0007] A locking rod is fixedly connected to the end of the isolation mesh fabric away from the rotating rod. A first C-shaped retaining ring, adapted to the locking rod, is fixedly provided on the side of the fixing sleeve away from the opening to fix the locking rod on the isolation mesh fabric to another fixing sleeve. This quick-connect structure of the C-shaped retaining ring and locking rod allows for rapid connection between adjacent fixing sleeves without additional tools, significantly improving the assembly efficiency of the isolation device. The connection process requires only one hand and results in a compact structure after connection.

[0008] Preferably, the folding support leg includes a lifting rod slidably inserted into the bottom of the fixed sleeve via a groove, three first counterweights circumferentially hinged to the bottom of the fixed sleeve, and three second counterweights circumferentially hinged to the bottom of the lifting rod, with the top of the second counterweights hinged to the top of the first counterweights. Through the foldable triangular support structure design, the support angle can be flexibly adjusted according to the flatness of the ground, improving the anti-tipping ability of the isolation device; the sliding adjustment function of the lifting rod can adapt to different ground height differences, and together with the hinged combination of the first and second counterweights, a stable triangular support base is formed in the unfolded state, significantly enhancing the overall stability of the device; when folded for storage, the support leg can be tightly fitted to the bottom of the fixed sleeve, reducing storage space occupation and facilitating handling and carrying.

[0009] Preferably, to increase the weight of the counterweights, both the first and second counterweights are filled with cement. By filling the counterweights with high-density cement material, the weight of a single counterweight is significantly increased, thereby improving the overall support and wind resistance of the folding legs, ensuring the stability of the isolation device in complex outdoor environments, and avoiding the risk of tipping over due to insufficient counterweight.

[0010] Preferably, to ensure the stability of the support: the bottom of the fixing sleeve has a vertical groove communicating with the recess, and a lifting plate fixedly connected to the top of the lifting rod is provided in the vertical groove. A screw is threaded into the end of the lifting plate away from the lifting rod, and a knob that abuts against the outer wall of the fixing sleeve is fixedly connected to the end of the screw away from the lifting plate. Through the threaded transmission mechanism between the screw and the lifting plate, the vertical position of the lifting rod is precisely locked, avoiding slippage of the lifting rod due to vibration or external force, ensuring that the folding legs remain stable in both the unfolded and closed states, and improving the reliability and safety of the device during use.

[0011] Preferably, to facilitate the positioning of the locking rod when the isolation netting is folded and stored, a second C-shaped retaining ring is fixedly connected to the fixing sleeve corresponding to the opening for engaging the locking rod. This provides a dedicated fixing position for the locking rod when the isolation netting is stored, preventing the locking rod from swaying and causing the netting to loosen or wear, ensuring a compact overall structure in the stored state, facilitating storage and transportation, and protecting the edges of the isolation netting from external pulling damage.

[0012] Preferably, to facilitate the winding of the isolation netting: the top of the rotating rod passes through the fixed sleeve and is fixedly connected to a handle. The ergonomic design of the handle provides a convenient point of force application, allowing operators to easily drive the rotating rod to quickly wind or unwind the isolation netting, reducing manual labor intensity and improving winding and unwinding efficiency. This is especially suitable for emergency repair scenarios requiring frequent adjustments to the isolation range.

[0013] This application significantly reduces the storage volume of the device through the storage structure design of folding legs and roll-up isolation netting. Combined with the quick-connect structure of the first C-shaped retaining ring and locking rod, it enables tool-free convenient handling and rapid on-site assembly, effectively improving the efficiency of power emergency repair isolation operations.

[0014] This application provides a dedicated fixing position for the locking bar when storing the isolation netting, preventing the locking bar from shaking randomly and causing the netting to become loose or worn. This ensures that the overall structure of the device is compact when stored, making it easy to store and transport, while also protecting the edges of the isolation netting from external pulling damage.

[0015] This application utilizes a foldable triangular support structure design, which allows for flexible adjustment of the support angle based on ground flatness, thereby enhancing the anti-tipping capability of the isolation device. The sliding adjustment function of the lifting rod can adapt to different ground height differences. Combined with the hinged combination of the first and second counterweights, a stable triangular support base is formed in the unfolded state, significantly enhancing the overall stability of the device. When folded for storage, the legs can be tightly fitted to the bottom of the fixed sleeve, reducing storage space occupation and facilitating handling and carrying. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] This embodiment provides a rapid isolation device for emergency repair of power grid line faults, such as... Figure 1-3 As shown, the isolation device includes a fixed sleeve 1 with a folding support leg 2 at the bottom. The fixed sleeve 1 has a through opening 11, and a rotating rod 3 is rotatably mounted inside the fixed sleeve 1. An isolation mesh 31 is wound on the rotating rod 3, and one end of the isolation mesh 31 passes through the opening 11 and extends to the outside of the fixed sleeve 1. Through the storage structure design of the folding support leg 2 and the wound isolation mesh 31, the storage volume of the device is greatly reduced. Combined with the quick-connect structure of the first C-shaped retaining ring 4 and the locking rod 32, tool-free convenient handling and rapid on-site assembly are achieved, effectively improving the efficiency of power emergency repair isolation operations.

[0023] A locking rod 32 is fixedly connected to the end of the isolation netting 31 away from the rotating rod 3. A first C-shaped retaining ring 4, adapted to the locking rod 32, is fixedly provided on the side of the fixed sleeve 1 away from the opening 11 to fix the locking rod 32 on the isolation netting 31 to another fixed sleeve 1. The quick-connect structure of the C-shaped retaining ring and the locking rod 32 allows for rapid connection between adjacent fixed sleeves 1 without additional tools, significantly improving the assembly efficiency of the isolation device. The connection process requires only one hand, and the structure is compact after connection. During assembly, the isolation netting 31 is pulled out from the opening 11 of the fixed sleeve 1 by holding the locking rod 32. The locking rod 32 is aligned with the opening of the first C-shaped retaining ring 4 on the adjacent fixed sleeve 1 and pushed in along the inner wall of the retaining ring. The elastic deformation of the C-shaped retaining ring locks the end of the locking rod 32, forming a stable mechanical connection. During disassembly, the locking rod 32 can be pulled out by applying force in the opposite direction, achieving rapid separation.

[0024] When in use, first unfold the folding support leg 2 to support the fixed sleeve 1. Pull the locking rod 32 to drive the rotating rod 3 to rotate and release the isolation net 31. Squeeze the locking rod 32 into the opening of the first C-shaped retaining ring 4 of the adjacent fixed sleeve 1. Use the elastic limit of the C-shaped retaining ring to achieve quick connection. When storing, reverse the operation. Roll up the net by rotating the rod 3. The folding support leg 2 fits into the bottom of the fixed sleeve 1 to form a compact and portable overall structure.

[0025] The folding support leg 2 includes a lifting rod 21 that is slidably inserted into the bottom of the fixed sleeve 1 via a groove, three first counterweights 22 that are circumferentially hinged to the bottom of the fixed sleeve 1, and three second counterweights 23 that are circumferentially hinged to the bottom of the lifting rod 21, with the top of the second counterweight 23 hinged to the top of the first counterweight 22. Through the foldable triangular support structure design, the support angle can be flexibly adjusted according to the flatness of the ground, improving the anti-tipping ability of the isolation device. The sliding adjustment function of the lifting rod 21 can adapt to different ground height differences. Combined with the hinged combination of the first counterweights 22 and the second counterweights 23, a stable triangular support base is formed in the unfolded state, significantly enhancing the overall stability of the device. When folded for storage, the support leg can be tightly fitted to the bottom of the fixed sleeve 1, reducing storage space occupation and facilitating handling and carrying. In use, the three first counterweights 22 and second counterweights 23 are unfolded circumferentially from the bottom of the fixed sleeve 1. The second counterweight 23 is hinged to the first counterweight 22 to form a triangular support structure centered on the fixed sleeve 1. By adjusting the extension length of the lifting rod 21, it can adapt to different ground heights and enhance the support stability by utilizing the gravity of the counterweights. When storing, the lifting rod 21 is extended out of the groove, and the first counterweights 22 and second counterweights 23 are folded and fitted to the bottom of the fixed sleeve 1 to achieve compact storage.

[0026] To increase the weight of the counterweights, both the first counterweight 22 and the second counterweight 23 are filled with cement. By filling the counterweights with high-density cement, the weight of a single counterweight is significantly increased, thereby enhancing the overall support and wind resistance of the folding leg 2. This ensures the stability of the isolation device in complex outdoor environments and avoids the risk of tipping over due to insufficient counterweight. Cement is evenly distributed as a filler in the internal cavities of the first counterweight 22 and the second counterweight 23. Its high density increases the mass of the counterweights. When the folding leg 2 unfolds to form a triangular support, the weight of the counterweights is transferred to the ground through the hinge point, forming a stable supporting torque that counteracts the lateral force generated when the isolation netting 31 is stretched.

[0027] To ensure the stability of the support: the bottom of the fixed sleeve 1 has a vertical groove 12 communicating with the recess. A lifting plate 24, fixedly connected to the top of the lifting rod 21, is installed within the vertical groove 12. A screw 25 is threadedly inserted into the end of the lifting plate 24 away from the lifting rod 21, and a knob 251, abutting against the outer wall of the fixed sleeve 1, is fixedly connected to the end of the screw 25 away from the lifting plate 24. Through the threaded transmission mechanism between the screw 25 and the lifting plate 24, the vertical position of the lifting rod 21 is precisely locked, preventing slippage of the lifting rod 21 due to vibration or external force. This ensures the stability of the folding support leg 2 in both unfolded and closed states, improving the reliability and safety of the device during use. When the height of the lifting rod 21 needs to be adjusted, the knob 251 is rotated to drive the screw 25 to rotate. The screw 25 engages with the threaded hole of the lifting plate 24, driving the lifting plate 24 to slide up and down in the vertical groove 12, thereby causing the lifting rod 21 to extend or retract. After adjusting to the target height, the end face of the knob 251 is in close contact with the outer wall of the fixed sleeve 1, using friction to lock the position of the screw 25 and prevent the lifting rod 21 from sliding on its own.

[0028] To facilitate the positioning of the locking rod 32 when the isolation netting 31 is folded and stored, a second C-shaped retaining ring 5 is fixedly connected to the corresponding opening 11 on the fixing sleeve 1 for the locking rod 32 to engage. This provides a dedicated fixing position for the locking rod 32 when the isolation netting 31 is stored, preventing the locking rod 32 from swaying and causing the netting to loosen or wear, ensuring a compact overall structure in the stored state, facilitating storage and transportation, and protecting the edges of the isolation netting 31 from external pulling damage. When storing the isolation netting 31, the netting is wound onto the rotating rod 3 using the handle 33. Finally, the locking rod 32 is aligned with the opening of the second C-shaped retaining ring 5 on the fixing sleeve 1, and pressure is applied to engage the locking rod 32 inside the retaining ring. The elasticity of the inner wall of the C-shaped retaining ring secures the locking rod 32, preventing the netting from loosening during the winding process.

[0029] Both the first C-shaped retaining ring 4 and the second C-shaped retaining ring 5 have anti-slip textures on their inner walls. By adding these textures, the friction between the locking rod 32 and the retaining ring is increased, effectively preventing loosening due to vibration, wind, or other external forces. This improves the reliability of the connection structure, ensuring the isolation device will not detach due to accidental force during use and guaranteeing a safe isolation effect at power repair sites. The anti-slip textures use a toothed or mesh-like structure. When the locking rod 32 is engaged with the C-shaped retaining ring, the textures tightly interlock with the surface of the locking rod 32, creating a mechanical stopping effect that counteracts lateral or longitudinal external forces. Even under high-frequency vibration or strong wind conditions, the locking rod 32 remains stably fixed within the retaining ring.

[0030] To facilitate the winding of the isolation netting 31, a handle 33 is fixedly connected to the top of the rotating rod 3 through the fixed sleeve 1. The ergonomic design of the handle 33 provides a convenient point of force application, allowing operators to easily drive the rotating rod 3 to rotate, enabling rapid winding or unwinding of the isolation netting 31. This reduces manual labor intensity and improves winding and unwinding efficiency, making it particularly suitable for emergency repair scenarios requiring frequent adjustments to the isolation range. The handle 33 is fixedly connected to the rotating rod 3. When winding the isolation netting 31, rotating the handle 33 clockwise causes the rotating rod 3 to rotate synchronously, and the netting is evenly wound around the surface of the rotating rod 3. When unwinding the netting, rotating the handle 33 counterclockwise or directly pulling the locking rod 32 causes the rotating rod 3 to rotate in the opposite direction, and the netting extends from the opening 11. The operation is effortless and controllable.

[0031] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
