Description

Technical Field

[0001] This invention belongs to the field of power distribution network operation technology, and particularly relates to equipment and methods for live-line operation and diversion construction in power distribution networks. Background Technology

[0002] Live-line work in power distribution networks is an advanced power construction technology that uses temporary bypass channels (diversion lines) built on live equipment to transfer load current without interrupting power supply, thereby safely carrying out equipment maintenance, replacement, capacity expansion, and other work. When performing live-line work in power distribution networks, diversion construction equipment is required to guide the load current.

[0003] Chinese patent (CN120016360B) discloses a live-line power distribution network diversion construction equipment, including an insulating rod with an extension rod movably connected to its outer wall. A diversion frame is fixedly connected to the top of the extension rod. By incorporating a transmission plate, a pressing spring block, a connecting plate, a second pressing spring block, a pressure plate main plate, a spring pressure plate, an internal structure of the pressing spring block, a bolt rotating rod with conical teeth, a bolt mounting rotating rod, a bolt fastening plate, gears, a bolt rotating groove, a fixing rotating block, a limiting rotating rod, a limiting rotating block, and a limiting spring, the equipment can achieve stable fixation of the diversion line and the hook to the tray body, improving the safety and stability of the operation. Simultaneously, it allows for rapid fixing and disassembly of the tray body and the hook, improving work efficiency. This design not only simplifies the operation process but also enhances the practicality and adaptability of the equipment, bringing convenience to actual operations. While current diversion construction equipment can achieve diversion, its overall size is large and not portable. Furthermore, because the main current is not interrupted during operation, there is still a significant risk of electric shock during construction, and work safety cannot be guaranteed. In addition, it cannot quickly and stably position the conductor, so the actual application effect cannot be guaranteed and certain improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the problems of current equipment being neither portable nor safe, and to propose a live-line working and diversion construction device and method for power distribution networks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a live-line working device for power distribution networks, comprising a main grid clamp and a diversion grid clamp, the main grid clamp and the diversion grid clamp being arranged side by side, each having an insulating gripping ring, a side groove, and an installation groove; a conductor groove being provided on the inner bottom of each of the main grid clamp and the diversion grid clamp; a conductor insulation positioning mechanism being provided above each conductor groove; and a spraying assembly and a fire control assembly being provided above each conductor insulation positioning mechanism; an insulating stud being rotatably installed inside each of the main grid clamp and the diversion grid clamp, one end of which is connected to the diversion grid clamp. The internal threaded hole provides a threaded connection, and the other end of the insulated stud extends to provide an insulated turntable. The conductor insulation positioning mechanism is rotatably installed in the side groove. The conductor insulation positioning mechanism is used for the rapid positioning and installation of the conductor. The fire control component is installed in the installation groove. The fire control component is used for temperature monitoring and short-circuit spontaneous combustion control during the diversion construction. The bottom of the installation groove is provided with a bottom cover. The spraying component is installed in the material hole at the bottom of the bottom cover. The spraying component is used for the spraying of fire-resistant agent and high-pressure carbon dioxide. The main grid clamp has an internal insulation component, which is movably connected to the side hole provided inside the diversion grid clamp.

[0006] The following are further optimizations and / or improvements to one of the above-mentioned technical solutions: The aforementioned conductor insulation positioning mechanism includes a mounting cover, which is rotatably mounted inside the side groove via mounting shafts on its two outer walls. A torsion spring is provided on the outside of the mounting shaft. One end of the torsion spring is fixedly connected to the side wall of the side groove. A telescopic frame is movably mounted inside the mounting cover via a built-in spring. An anti-detachment plate is fixedly mounted at the bottom of the telescopic frame. The bottom end of the anti-detachment plate is snapped into a positioning groove provided on the surface of the main grid clamp. A multi-claw positioning accessory is fixedly mounted on the inside of the telescopic frame via a connecting shaft. The multi-claw positioning accessory includes a main positioning claw, and secondary positioning claws are fixedly mounted on both sides of the main positioning claw via connecting frames.

[0007] Both the main positioning claw and the secondary positioning claw have bottom holes on their bottom surfaces, and anti-slip positioning cones are movably installed inside the bottom holes via positioning springs.

[0008] The aforementioned insulation assembly includes an insulating column, which is fixedly installed inside the main grid clamp. Multiple insulating wheel frames are fixedly installed on the outer surface of the insulating column. Insulating guide wheels are rotatably installed on the inner side of each insulating wheel frame via a rotating shaft. The insulating guide wheels are in rolling connection with the limiting wheel grooves provided on the inner wall of the side hole.

[0009] The aforementioned fire control assembly includes a high-pressure airbag and a mounting base. The high-pressure airbag is located inside the mounting groove, and the mounting base is fixedly installed on one inner wall of the mounting groove. A thermal expansion block is provided inside the mounting base, and a needle tip is provided on one outer wall of the thermal expansion block. The needle tip is located on one side of the high-pressure airbag, and the interior of the high-pressure airbag is filled with high-pressure carbon dioxide gas and fire extinguishing agent powder.

[0010] The aforementioned spraying assembly includes a connecting pipe, which is fixedly installed in a material hole at the bottom of the bottom cover. A conical material disc is rotatably installed at the bottom end of the connecting pipe, and multiple material holes are provided on the bottom surface of one side of the conical material disc.

[0011] A feeding rack is fixedly installed on one side of the outer wall of the connecting pipe, and the side wall of the feeding rack is in contact with the bottom surface of the conical material tray.

[0012] The present invention also provides a method for using the above-mentioned live-line working and diversion construction equipment for power distribution networks, comprising the following steps: S1. When in use, push the telescopic frame of the main grid clamp upward so that the bottom end of the anti-detachment plate is disengaged from the positioning groove. At this time, the conductor insulation positioning mechanism can be rotated freely. Use the insulation gripping ring to place the main conductor inside the conductor groove. Release the telescopic frame again, and the telescopic frame can automatically reset. The main positioning claw and multiple secondary positioning claws can be locked above the conductor to achieve rapid positioning of the conductor. S2. When the size of the conductor being positioned is smaller than the size of the conductor groove, the telescopic frame is directly deflected inward, causing the anti-detachment plate to be stuck in the corresponding positioning groove. This causes the main positioning claw and multiple secondary positioning claws to deflect at an angle, firmly squeezing the conductor to one side of the conductor groove. Furthermore, when positioning the conductor, multiple anti-slip positioning cones can continuously squeeze the positioning conductor under the action of the positioning spring, further ensuring the positioning effect of the conductor and thus avoiding unnecessary displacement of the entire equipment during subsequent drainage. S3. After the main conductor and the main grid clamp are installed, the current-diverting grid clamp and the external current-diverting conductor are positioned and combined according to the above operation. Since the insulation components and insulation studs are installed, the current will not be conducted between the main grid clamp and the current-diverting grid clamp at this time. At this time, the worker can operate without risk. S4. After the current-carrying grid clamp and the current-carrying conductor are positioned, the insulating stud is rotated directly through the insulating turntable. When the insulating stud rotates, it can drive the current-carrying grid clamp to approach the main grid clamp. During the above process, the insulating guide wheel can roll in the limit wheel groove set on the inner wall of the side hole of the current-carrying grid clamp to ensure the stable movement of the entire current-carrying grid clamp until the main grid clamp and the current-carrying grid clamp finally fit together, so that the current is carried out. S5. After the current diversion operation is completed, the current is conducted between the equipment. During this process, if a short circuit occurs or the conductor heat accumulates and causes spontaneous combustion, the temperature on the outside of the conductor will rise suddenly. The thermal expansion block can quickly sense the high temperature and expand. The thermal expansion block can drive the needle tip to expand and shift. When the needle tip pierces the high-pressure airbag, the high-pressure carbon dioxide gas and extinguishing agent powder in the high-pressure airbag will quickly rush into the connecting pipe of the spray assembly. Since the bottom of the connecting pipe is only provided with a material hole on one side, a large amount of high-pressure gas and powder will be sprayed out through the material hole. Due to the huge pressure on one side of the material hole, the force on the conical material plate will become unbalanced. The conical material plate can rotate automatically and spray the sprayed high-pressure gas and extinguishing agent to the outside to control the fire. When the conical material plate rotates, the material rack can also disperse the extinguishing agent.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, a conductor insulation positioning mechanism is provided. During use, the telescopic frame is pushed upwards, causing the bottom end of the anti-detachment plate to disengage from the positioning groove. At this time, the conductor insulation positioning mechanism can be freely rotated. The insulating gripper ring places the main conductor inside the conductor groove. Releasing the telescopic frame again allows it to automatically reset. The main positioning claw and multiple secondary positioning claws can then be engaged above the conductor, achieving rapid conductor positioning. When the size of the positioned conductor is smaller than the size of the conductor groove, the telescopic frame is directly deflected inwards, causing the anti-detachment plate to engage in the corresponding positioning groove. This causes the main positioning claw and multiple secondary positioning claws to deflect at an angle, firmly pressing the conductor against one side of the conductor groove. Furthermore, during conductor positioning, multiple anti-slip positioning cones continuously compress the positioned conductor under the action of the positioning spring. To ensure effective conductor positioning and prevent unnecessary displacement of the entire device during subsequent current diversion, this design incorporates an insulated positioning structure with an external insulated gripping mechanism. This prevents electric shock and ensures operational safety when the device is installed on the main line, while also enabling rapid conductor positioning, significantly improving positioning efficiency and effectiveness. The positioning structure consists of multiple sets of positioning claws with ample gaps between them. This design not only ensures effective conductor positioning but also allows for efficient heat dissipation, preventing heat concentration. Furthermore, this positioning structure can accommodate conductors of different specifications, making it highly adaptable. The device is also compact, portable, and easy to use.

[0014] 2. In this invention, by setting an insulating component and an insulating stud between the main grid clamp and the diversion grid clamp, after the main conductor and the main grid clamp are installed, the diversion grid clamp can be combined with the external diversion conductor. Due to the insulating component and the insulating stud, the current will not be conducted between the main grid clamp and the diversion grid clamp at this time, and the worker can operate without risk. After the diversion grid clamp and the diversion conductor are positioned, the insulating stud can be rotated directly by the insulating turntable. When the insulating stud rotates, it can drive the diversion grid clamp and the main grid clamp closer. During the above process, the insulating guide wheel can roll in the limiting wheel groove set on the inner wall of the side hole of the diversion grid clamp to ensure the stable movement of the diversion grid clamp as a whole until the main grid clamp and the diversion grid clamp are finally attached, so that the current is diverted. This further ensures the safety of the equipment during use, avoids electric shock and other situations, and further improves the application effect of the equipment.

[0015] 3. In this invention, by matching the spraying component and the fire control component, after the current is conducted between the equipment after the diversion operation is completed, if a short circuit or heat accumulation in the conductor leads to spontaneous combustion, the temperature on the outside of the conductor will rise suddenly. The thermal expansion block can quickly sense the high temperature and expand. The thermal expansion block can drive the needle tip to expand and shift. When the needle tip pierces the high-pressure airbag, the high-pressure carbon dioxide gas and extinguishing agent powder in the high-pressure airbag will quickly rush into the connecting pipe of the spraying component. Since the bottom of the connecting pipe is only provided with a material hole on one side, a large amount of high-pressure gas and powder will be sprayed out through the material hole. Due to the huge pressure on one side of the material hole, the force on the conical material plate will become unbalanced. The conical material plate can rotate automatically, spraying the sprayed high-pressure gas and extinguishing agent to the outside to control the fire. When the conical material plate rotates, the feeding rack can also disperse the extinguishing agent, further improving the diffusion range of the extinguishing agent powder, improving its fire control effect, and further improving the emergency response capability of the equipment.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please see Figures 1-10This invention provides a live-line working device for power distribution networks, comprising a main grid clamp 1 and a diversion grid clamp 4. The diversion grid clamp 4 is provided on one side of the main grid clamp 1. Insulating gripping rings 2 are fixedly installed on the top surfaces of both the main grid clamp 1 and the diversion grid clamp 4. Conductor grooves 7 are provided on the inner sides of both the main grid clamp 1 and the diversion grid clamp 4. An insulating stud 13 is rotatably installed inside the main grid clamp 1. One end of the insulating stud 13 is threadedly connected to a threaded hole provided inside the diversion grid clamp 4. An insulating turntable 8 is provided extending from the other end of the insulating stud 13. The main components include an insulation component 3, a conductor insulation positioning mechanism 5, a spraying component 11, and a flame control component 15. The conductor insulation positioning mechanism 5 is rotatably installed in a side groove 9 on one side of the main grid clamp 1. The conductor insulation positioning mechanism 5 is used for rapid positioning and installation of the conductor. The flame control component 15 is installed in an installation groove 14 inside the main grid clamp 1. The flame control component 15 is used for temperature monitoring and short-circuit spontaneous combustion control during the diversion construction. A bottom cover 10 is provided at the bottom of the installation groove 14. The spraying component 11 is installed in a material hole at the bottom of the bottom cover 10. The spraying component 11 is used for spraying fire-resistant agent and high-pressure carbon dioxide. An insulation component 3 is installed inside the main grid clamp 1. The insulation component 3 is movably connected to a side hole 12 inside the diversion grid clamp 4.

[0029] The conductor insulation positioning mechanism 5 includes a mounting cover 53. The mounting cover 53 is rotatably mounted inside the side groove 9 via mounting shafts 52 provided on its two outer walls. A torsion spring 51 is provided outside the mounting shaft 52. One end of the torsion spring 51 is fixedly connected to the side wall of the side groove 9. A telescopic frame 55 is movably mounted inside the mounting cover 53 via a built-in spring 54. An anti-detachment plate 56 is fixedly mounted at the bottom of the telescopic frame 55. The bottom end of the anti-detachment plate 56 is snapped into the positioning groove 6 provided on the surface of the main grid clamp 1. A multi-claw positioning accessory 57 is fixedly mounted inside the telescopic frame 55 via a connecting shaft.

[0030] The multi-jaw positioning accessory 57 includes a main positioning jaw 571. Secondary positioning jaws 572 are fixedly installed on both sides of the main positioning jaw 571 through connecting brackets. Bottom holes 573 are provided on the bottom surfaces of the main positioning jaw 571 and the secondary positioning jaws 572. An anti-slip positioning cone 575 is movably installed inside the bottom hole 573 through a positioning spring 574.

[0031] The specific implementation method is as follows: When in use, push the telescopic frame 55 upward so that the bottom end of the anti-detachment plate 56 is disengaged from the positioning groove 6. At this time, the conductor insulation positioning mechanism 5 can be rotated freely. The main conductor is placed inside the conductor groove 7 by using the insulation gripping ring 2. Release the telescopic frame 55 again, and the telescopic frame 55 can automatically reset. The main positioning claw 571 and multiple secondary positioning claws 572 can be locked above the conductor to achieve rapid positioning of the conductor. When the size of the positioned conductor is smaller than the size of the conductor groove 7, the telescopic frame 55 is directly deflected inward so that the anti-detachment plate 56 is locked in the corresponding positioning groove 6. This causes the main positioning claw 571 and multiple secondary positioning claws 572 to deflect at an angle, firmly squeezing the conductor on one side of the conductor groove 7. When positioning the conductor, multiple anti-slip positioning cones 575 can continuously squeeze the positioned conductor under the action of the positioning spring 574 to further ensure the positioning effect of the conductor, thereby avoiding unnecessary displacement of the entire equipment during subsequent current diversion.

[0032] This design incorporates an insulated conductor positioning mechanism 5 with an external insulated gripping structure. This prevents electric shock and ensures operational safety when the device is installed on the main line. It also enables rapid conductor positioning, significantly improving positioning efficiency and effectiveness. The positioning structure consists of multiple sets of positioning claws with ample gaps between them. This design not only ensures effective conductor positioning but also allows for efficient heat dissipation, preventing heat concentration. Furthermore, this positioning structure can accommodate conductors of different specifications, making it highly adaptable.

[0033] Please see Figure 8 The insulation component 3 includes an insulation post 31, which is fixedly installed inside the main grid clamp 1. Multiple insulation wheel frames 32 are fixedly installed on the outer surface of the insulation post 31. Insulation guide wheels 33 are rotatably installed on the inner side of each of the multiple insulation wheel frames 32 via a rotating shaft. The insulation guide wheels 33 are in rolling connection with the limiting wheel groove provided on the inner wall of the side hole 12.

[0034] The specific implementation method is as follows: After the main conductor and the main grid clamp 1 are installed, the current-diverting grid clamp 4 can be combined with the external current-diverting conductor. Since the insulating component 3 and the insulating stud 13 are provided, the current will not be conducted between the main grid clamp 1 and the current-diverting grid clamp 4. At this time, the worker can operate without risk. After the current-diverting grid clamp 4 and the current-diverting conductor are positioned, the insulating stud 13 is rotated directly through the insulating turntable 8. When the insulating stud 13 rotates, it can drive the current-diverting grid clamp 4 to move closer to the main grid clamp 1. During the above process, the insulating guide wheel 33 can roll in the limiting wheel groove provided on the inner wall of the side hole 12 of the current-diverting grid clamp 4 to ensure the stable movement of the entire current-diverting grid clamp 4 until the main grid clamp 1 and the current-diverting grid clamp 4 are finally attached, so that the current is diverted. This further ensures the safety of the equipment during use, avoids electric shock and other situations, and further improves the application effect of the equipment.

[0035] Please see Figures 9-10 The fire control assembly 15 includes a high-pressure airbag 151 and a mounting base 154. The high-pressure airbag 151 is disposed inside the mounting groove 14. The mounting base 154 is fixedly installed on one inner wall of the mounting groove 14. A thermal expansion block 153 is disposed inside the mounting base 154. A needle tip 152 is disposed on one outer wall of the thermal expansion block 153. The needle tip 152 is located on one side of the high-pressure airbag 151. The high-pressure airbag 151 is filled with high-pressure carbon dioxide gas and fire extinguishing agent powder.

[0036] The spraying assembly 11 includes a connecting pipe 111, which is fixedly installed in a material hole at the bottom of the bottom cover 10. A conical material plate 112 is rotatably installed at the bottom end of the connecting pipe 111. Multiple material holes 114 are provided on the bottom surface of the conical material plate 112. A feeding frame 113 is fixedly installed on one outer wall of the connecting pipe 111. One side wall of the feeding frame 113 is in contact with the bottom surface of the conical material plate 112.

[0037] The specific implementation method is as follows: After the current diversion operation is completed, the current is conducted between the equipment. During this process, if a short circuit occurs or the conductor accumulates heat and causes spontaneous combustion, the temperature on the outside of the conductor will rise suddenly. The thermal expansion block 153 can quickly sense the high temperature and expand. The thermal expansion block 153 can drive the needle tip 152 to expand and displace. When the needle tip 152 pierces the high-pressure airbag 151, the high-pressure carbon dioxide gas and extinguishing agent powder in the high-pressure airbag 151 will quickly rush into the connecting pipe 111 of the spray assembly 11. Since the bottom of the connecting pipe 111 is only in A feed hole 114 is provided on one side, through which a large amount of high-pressure gas and powder are ejected. Due to the huge pressure on one side of the feed hole 114, the cone-shaped feed plate 112 will become unbalanced. The cone-shaped feed plate 112 can rotate automatically, spraying the ejected high-pressure gas and extinguishing agent to the outside to control the fire. When the cone-shaped feed plate 112 rotates, the feeding frame 113 can also disperse the extinguishing agent, further improving the diffusion range of the extinguishing agent powder, improving its fire control effect, and further improving the emergency response capability of the equipment.

[0038] Example 2: This embodiment provides a method for using the above-mentioned live-line working and diversion construction equipment for power distribution networks, including the following steps: S1. When in use, push the telescopic frame 55 of the main grid clamp 1 upward so that the bottom end of the anti-detachment plate 56 is disengaged from the positioning groove 6. At this time, the conductor insulation positioning mechanism 5 can be rotated freely. Use the insulation gripping ring 2 to place the main conductor inside the conductor groove 7. Release the telescopic frame 55 again, and the telescopic frame 55 can automatically reset. The main positioning claw 571 and multiple secondary positioning claws 572 can be locked above the conductor to achieve rapid positioning of the conductor. S2. When the size of the conductor being positioned is smaller than the size of the conductor groove 7, the telescopic frame 55 is deflected inwards directly, so that the anti-detachment plate 56 is stuck in the corresponding positioning groove 6, causing the main positioning claw 571 and multiple secondary positioning claws 572 to deflect at an angle, firmly squeezing the conductor to one side of the conductor groove 7. When positioning the conductor, multiple anti-slip positioning cones 575 can continuously squeeze the positioning conductor under the action of the positioning spring 574, further ensuring the positioning effect of the conductor, thereby avoiding unnecessary displacement of the entire equipment during subsequent drainage. S3. After the main conductor and the main grid clamp 1 are installed, the current-draining grid clamp 4 can be combined with the external current-draining conductor. Since the insulation component 3 and the insulation stud 13 are installed, the current will not be conducted between the main grid clamp 1 and the current-draining grid clamp 4. At this time, the worker can operate without risk. S4. After the current-carrying grid clamp 4 and the current-carrying conductor are positioned, the insulating stud 13 is rotated directly through the insulating turntable 8. When the insulating stud 13 rotates, it can drive the current-carrying grid clamp 4 to approach the main grid clamp 1. During the above process, the insulating guide wheel 33 can roll in the limiting wheel groove set on the inner wall of the side hole 12 of the current-carrying grid clamp 4 to ensure the stable movement of the entire current-carrying grid clamp 4 until the main grid clamp 1 and the current-carrying grid clamp 4 finally fit together, so that the current is carried out. S5. After the current diversion operation is completed, the current is conducted between the equipment. During this process, if a short circuit occurs or the conductor heat accumulates and causes spontaneous combustion, the temperature on the outside of the conductor will rise suddenly. The thermal expansion block 153 can quickly sense the high temperature and expand. The thermal expansion block 153 can drive the needle tip 152 to expand and move. When the needle tip 152 pierces the high-pressure airbag 151, the high-pressure carbon dioxide gas and extinguishing agent powder in the high-pressure airbag 151 will quickly rush into the connecting pipe 111 of the spraying assembly 11. Since the bottom of the connecting pipe 111 is only provided with a material hole 114 on one side, a large amount of high-pressure gas and powder will be sprayed out through the material hole 114. Since the material hole 114 is subjected to huge pressure on one side, the force on the conical material plate 112 will become unbalanced. The conical material plate 112 can rotate automatically and spray the sprayed high-pressure gas and extinguishing agent to the outside to control the fire. When the conical material plate 112 rotates, the feeding rack 113 can also disperse the extinguishing agent.

[0039] Working principle: When in use, push the telescopic frame 55 upward so that the bottom end of the anti-detachment plate 56 is disengaged from the positioning groove 6. At this time, the conductor insulation positioning mechanism 5 can be rotated freely. The main conductor is placed inside the conductor groove 7 by using the insulation gripping ring 2. Release the telescopic frame 55 again, and the telescopic frame 55 can automatically reset. The main positioning claw 571 and multiple secondary positioning claws 572 can be locked above the conductor to achieve rapid positioning of the conductor. When the size of the positioned conductor is smaller than the size of the conductor groove 7, the telescopic frame 55 is directly deflected inward so that the anti-detachment plate 56 is locked in the corresponding positioning groove 6. This causes the main positioning claw 571 and multiple secondary positioning claws 572 to deflect at an angle, firmly squeezing the conductor on one side of the conductor groove 7. When positioning the conductor, multiple anti-slip positioning cones 575 can continuously squeeze the positioned conductor under the action of the positioning spring 574 to further ensure the positioning effect of the conductor, thereby avoiding unnecessary displacement of the entire equipment during subsequent current diversion. After the main conductor and main grid clamp 1 are installed, the current-diverting grid clamp 4 can be combined with the external current-diverting conductor. Due to the presence of insulating components 3 and insulating studs 13, current will not be conducted between the main grid clamp 1 and the current-diverting grid clamp 4, allowing workers to operate without risk. After the current-diverting grid clamp 4 and the current-diverting conductor are positioned, the insulating studs 13 can be rotated directly through the insulating turntable 8. As the insulating studs 13 rotate, they can drive the current-diverting grid clamp 4 to approach the main grid clamp 1. During this process, the insulating guide wheel 33 can roll in the limiting wheel groove provided on the inner wall of the side hole 12 of the current-diverting grid clamp 4, ensuring the stable movement of the entire current-diverting grid clamp 4 until the main grid clamp 1 and the current-diverting grid clamp 4 finally come into contact, allowing the current to be diverted. After the current diversion operation is completed, the current is conducted between the equipment. During this process, if a short circuit occurs or the conductor heat accumulates and causes spontaneous combustion, the temperature on the outside of the conductor will rise suddenly. The thermal expansion block 153 can quickly sense the high temperature and expand. The thermal expansion block 153 can drive the needle tip 152 to expand and move. When the needle tip 152 pierces the high-pressure airbag 151, the high-pressure carbon dioxide gas and extinguishing agent powder in the high-pressure airbag 151 will quickly rush into the connecting pipe 111 of the spraying assembly 11. Since the bottom of the connecting pipe 111 is only provided with a material hole 114 on one side, a large amount of high-pressure gas and powder will be sprayed out through the material hole 114. Since the material hole 114 is subjected to huge pressure on one side, the force on the conical material plate 112 will become unbalanced. The conical material plate 112 can rotate automatically and spray the sprayed high-pressure gas and extinguishing agent to the outside to control the fire.

A material feeding frame is fixedly installed on the outer wall of one side of the connecting pipe, and the side wall of the material feeding frame is in contact with the bottom surface of the conical material disc.

10. The method of using the power distribution network live-line working diversion construction equipment according to any one of claims 1-9, characterized in that, Includes the following steps: S1. When in use, push the telescopic frame of the main grid clamp upward so that the bottom end of the anti-detachment plate is disengaged from the positioning groove. At this time, the conductor insulation positioning mechanism can be rotated freely. Use the insulation gripping ring to place the main conductor inside the conductor groove. Release the telescopic frame again, and the telescopic frame can automatically reset. The main positioning claw and multiple secondary positioning claws can be locked above the conductor to achieve rapid positioning of the conductor. S2. When the size of the conductor being positioned is smaller than the size of the conductor groove, the telescopic frame is directly deflected inward, causing the anti-detachment plate to be stuck in the corresponding positioning groove. This causes the main positioning claw and multiple secondary positioning claws to deflect at an angle, firmly squeezing the conductor to one side of the conductor groove. Furthermore, when positioning the conductor, multiple anti-slip positioning cones can continuously squeeze the positioning conductor under the action of the positioning spring, further ensuring the positioning effect of the conductor and thus avoiding unnecessary displacement of the entire equipment during subsequent drainage. S3. After the main conductor and the main grid clamp are installed, the current-diverting grid clamp and the external current-diverting conductor are positioned and combined according to the above operation. Since the insulation components and insulation studs are installed, the current will not be conducted between the main grid clamp and the current-diverting grid clamp at this time. At this time, the worker can operate without risk. S4. After the current-carrying grid clamp and the current-carrying conductor are positioned, the insulating stud is rotated directly through the insulating turntable. When the insulating stud rotates, it can drive the current-carrying grid clamp to approach the main grid clamp. During the above process, the insulating guide wheel can roll in the limit wheel groove set on the inner wall of the side hole of the current-carrying grid clamp to ensure the stable movement of the entire current-carrying grid clamp until the main grid clamp and the current-carrying grid clamp finally fit together, so that the current is carried out. S5. After the current diversion operation is completed, the current is conducted between the equipment. During this process, if a short circuit occurs or the conductor heat accumulates and causes spontaneous combustion, the temperature on the outside of the conductor will rise suddenly. The thermal expansion block can quickly sense the high temperature and expand. The thermal expansion block can drive the needle tip to expand and shift. When the needle tip pierces the high-pressure airbag, the high-pressure carbon dioxide gas and extinguishing agent powder in the high-pressure airbag will quickly rush into the connecting pipe of the spray assembly. Since the bottom of the connecting pipe is only provided with a material hole on one side, a large amount of high-pressure gas and powder will be sprayed out through the material hole. Due to the huge pressure on one side of the material hole, the force on the conical material plate will become unbalanced. The conical material plate can rotate automatically and spray the sprayed high-pressure gas and extinguishing agent to the outside to control the fire. When the conical material plate rotates, the material rack can also disperse the extinguishing agent.
