Description

[0001] This invention relates to the field of live-line working tools for power distribution networks, and in particular to a push-type adaptive anti-loosening rapid current diversion device and its usage method. Background Technology

[0002] The 10kV distribution network is a key link connecting power sources and end users. Its power supply reliability is directly related to the continuity of enterprise production and the quality of electricity for people's lives. With industrial development, enterprise electricity load is rising, and distribution network capacity expansion and renovation are becoming more and more frequent. Live working has become the mainstream mode of such work. As a core piece of equipment, the performance of the rapid current diversion device directly determines the work efficiency, power outage duration and power supply reliability. It is the core support for shortening power outage time and ensuring enterprise production.

[0003] Currently, existing self-locking insulating rod operation methods using rapid current diversion devices and related patents, although achieving initial self-locking and rapid connection to meet the basic requirements for live current diversion, are difficult to adapt to high-requirement scenarios;

[0004] Existing devices mostly employ dual anti-loosening structures such as springs and pawls, threads and electromagnetic couplings, with anti-loosening torque generally ≤50N·m. These devices are prone to failure under strong winds and operational vibrations in mountainous areas. Furthermore, they lack redundant emergency unlocking designs, making the loosening operation cumbersome and prone to delaying work progress. They cannot meet the needs of short power outages, and their positioning and clamping accuracy is low. The guide structure has a fixed adaptation angle, making it prone to positioning deviation when working with thin wires below 10mm² or thick wires above 200mm². The clamping surface is a fixed structure, unable to adapt to multiple wire specifications, easily causing wire slippage or insulation damage, affecting operational safety and stability. They lack dual-state monitoring, only monitoring the clamping status or having no monitoring function at all, and do not consider current monitoring, making it impossible to determine circuit continuity. Poor contact can easily lead to work failure, prolonging power outage time. Additionally, the insulating rods are mostly one-piece or segmented with a length >1.2m, making them inconvenient to carry for climbing in mountainous areas and difficult to accurately align the overlapping position in complex spaces, resulting in insufficient operational flexibility.

[0005] The above problems seriously affect the reliability of power supply and cause a large number of users to lose their lives when power is cut off. Therefore, it is urgent to develop a push-type adaptive anti-loosening rapid diversion device and its usage method. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a push-type adaptive anti-loosening rapid drainage device and its usage method, thereby solving the technical problems of insufficient anti-loosening reliability, low positioning and clamping accuracy, lack of dual-state monitoring, poor adaptability to complex terrain, high labor intensity of operation, and insufficient adaptability to harsh environments in existing self-locking rapid drainage devices.

[0007] A push-type adaptive anti-loosening rapid drainage device includes a segmented insulating operating rod and a push-self-locking drainage mechanism. The push-self-locking drainage mechanism includes a push handle, a rotating plate, a transmission link, a first clamping block, and a second clamping block.

[0008] The segmented insulating operating rod is detachably mounted with a rotating shaft, which has a first strip-shaped through hole and a second strip-shaped through hole near its top position; the push handle is hinged to the rotating shaft, the rotating plate passes through the first strip-shaped through hole and is rotatably connected to the through hole, one end of the transmission connecting rod is hinged to the push handle, and the other end is hinged to the rotating plate, the second clamping block is fixedly installed on the end of the rotating plate away from the transmission connecting rod; a connecting plate is fixedly installed in the second strip-shaped through hole, and the first clamping block is fixedly installed on the connecting plate;

[0009] Furthermore: the segmented insulating operating rod is equipped with an anti-loosening mechanism, which includes a push-locking plate and a Velcro strap. The push-locking plate is fixedly installed at one end of the second clamping block, and anti-detachment side plates are provided on both sides of the second clamping block. A compression spring is fixedly installed between the anti-detachment side plates and the push-locking plate. The first clamping block has a slot adapted to the push-locking plate. The two ends of the Velcro strap are fixed to the push handle and the segmented insulating operating rod, respectively. After the device is clamped, it is wrapped and bound to achieve secondary anti-loosening.

[0010] Furthermore: the anti-loosening mechanism also includes a pawl and ratchet assembly, the ratchet is coaxially assembled and fixed with the rotating plate, a connecting rod is fixedly installed on the side wall of the rotating plate near the ratchet, the pawl is rotatably connected to the connecting rod, and a buffer spring is sleeved on the connecting rod, with the two ends of the buffer spring abutting against the inner wall of the pawl and the side wall of the rotating plate respectively;

[0011] Furthermore: an auxiliary pull rod is also fixedly installed on the inner wall of the pawl, and an emergency unlocking control rope is wrapped around the outer periphery of the auxiliary pull rod. The emergency unlocking control rope extends along the segmented insulated operating rod to the bottom of the rod body.

[0012] Furthermore: the segmented insulating operating rod includes at least 3 insulating rod units, each of which is detachably connected by a hexagonal quick-release buckle to achieve rapid assembly and disassembly and circumferential positioning. The segmented insulating operating rod is made of carbon fiber reinforced epoxy resin composite material and is coated with a superhydrophobic anti-flashover coating. The first clamping block and the second clamping block are both embedded with current-guiding copper busbars and elastic conductive sheets. The current-guiding copper busbars have a cross-sectional area of ​​≥150mm², and the elastic conductive sheets are made of beryllium bronze with a silver-plated surface. The contact surface with the wire is provided with a wavy anti-slip texture.

[0013] Furthermore, a dual monitoring and early warning mechanism is also provided, comprising a clamping force sensing unit, a current sensing unit, and an audible and visual early warning unit. The clamping force sensing unit is embedded in the inner contact surface of the first clamping block, the current sensing unit is fitted onto the outer side of the current-conducting copper busbar and insulated from it, and the audible and visual early warning unit is fixed to the middle of the segmented insulated operating rod and electrically connected to the clamping force sensing unit and the current sensing unit.

[0014] Further: A method of using a push-type adaptive anti-loosening rapid drainage device includes the following steps:

[0015] S1: Preparation and assembly before use: Check the segmented insulating rod unit, push-locking current-draining mechanism, anti-loosening mechanism, dual monitoring and early warning mechanism, current-guiding copper busbar, elastic conductive sheet and other components. Check that the carbon fiber rod body, superhydrophobic anti-flashover coating, beryllium bronze silver-plated elastic conductive sheet anti-slip texture are intact, all hinge points are adequately lubricated and the emergency unlocking control rope is normal. Connect the insulating rod unit through the hexagonal quick-release buckle, fix the emergency unlocking control rope on the auxiliary pull rod, start the monitoring and early warning mechanism, calibrate the sensor unit, set various thresholds, and debug the sound and light early warning unit to ensure normal operation and electrical connection.

[0016] S2: Target wire positioning and initial clamping: Hold the bottom of the segmented insulating rod, adjust the angle so that the two clamping blocks are aligned with the target drain wire and placed in the center. Slowly press the push handle, and drive the rotating plate to rotate around the first strip-shaped through hole through the transmission linkage, driving the second clamping block to move towards the first clamping block. Observe the data of the clamping force sensing unit. When the set pre-tightening threshold is reached, stop pushing to complete the pre-clamping.

[0017] S3: Multiple anti-loosening locking operation: After pre-clamping, slowly press the push handle. The rotating plate drives the coaxial ratchet to rotate synchronously. The pawl engages with the ratchet under the action of the buffer spring to achieve one-way locking. The second clamping block drives the push locking plate to embed into the first clamping block slot to complete the second-level mechanical locking. Finally, fix both ends of the Velcro cable tie to the middle of the push handle and the rod body, wrap it 2-3 times and tighten it to achieve the third-level anti-loosening reinforcement.

[0018] S4: Current diversion operation and real-time monitoring: After confirming the anti-loosening lock, start the current diversion operation. The current diversion current sensing unit collects the current data of the current diversion copper busbar in real time and calculates the current fluctuation coefficient. When it is greater than the preset current fluctuation coefficient, the sound and light warning unit issues a yellow warning. When the current is greater than the current diversion current warning threshold, a red warning is issued and the operation is stopped immediately. During the operation, the clamping force sensing unit continuously monitors. If the clamping force drops below 0.8F, the pressure is replenished to the preset clamping force range by pushing the handle.

[0019] S5: Operation Completion and Unlocking / Disassembly: After the drainage operation is completed, untie the wrapped Velcro straps, pull the emergency unlocking control rope at the bottom of the insulating rod, and drive the pawl to overcome the spring force of the buffer spring and disengage from the ratchet tooth groove through the auxiliary pull rod. After releasing the one-way lock, slowly release the push handle, so that the transmission linkage drives the rotating plate to rotate in the opposite direction. The second clamping block moves away from the first clamping block, and the push locking plate is pressed to disengage from the slot to complete the mechanical unlocking. Finally, sort and store each component.

[0020] Furthermore: the specific steps for positioning and initially clamping the target wire in S2 are as follows:

[0021] S2.1: The operator holds the segmented insulating rod at the bottom 1 / 3 with both hands, maintaining a safe distance between the body and the work area. The operator slowly adjusts the angle and height of the rod to ensure that the first and second clamping blocks are precisely aligned with the target guide wire. The operator ensures that the wire is centered on the first and second clamping blocks with uniform gaps on both sides. Taking advantage of the lightweight characteristics of the carbon fiber reinforced epoxy resin rod, the operator smoothly controls the first and second clamping blocks to move closer to the wire, controlling the initial distance to 5-10cm and gradually fine-tuning the distance to avoid the clamping blocks directly colliding with the wire insulation layer and causing damage.

[0022] S2.2: Then, press the push handle down slowly and evenly. The transmission linkage drives the rotating plate to rotate smoothly around the first strip-shaped through hole, causing the second clamping block to slowly move closer to the first clamping block fixed on the connecting plate. During the process, keep a close eye on the sound and light warning unit display module in the middle of the rod and observe the real-time data fed back by the clamping force sensing unit. When the value reaches the preset pre-tightening threshold, stop pushing immediately. At this time, the wave-shaped anti-slip texture of the beryllium bronze silver-plated elastic conductive sheet is initially attached to the wire, completing the pre-clamping positioning and preparing for subsequent multiple anti-loosening locking.

[0023] Furthermore: The specific operation steps of the multiple anti-loosening locking operation in S3 are as follows:

[0024] S3.1: After pre-clamping, keep your hand steady and press the push handle slowly and evenly, controlling the force evenly to avoid impact. This will drive the rotating plate to rotate smoothly around the first strip-shaped through hole. The ratchet, which is fixed coaxially with the rotating plate, will rotate synchronously. Under the elastic thrust of the buffer spring, the pawl will automatically and precisely engage with the ratchet tooth groove to achieve one-way locking and prevent the rotating plate from loosening in the opposite direction. After locking, check the status by visual observation and gently shaking the push handle to ensure that the compression of the buffer spring is within the range of 2-5mm, and that there is no loosening or abnormal noise in the engagement.

[0025] S3.2: Continue to fine-tune the pressing handle until the feedback value of the clamping force sensing unit reaches the preset F standard, which is 50-150N. At this time, the second clamping block synchronously drives the pushing and locking plate to accurately embed into the matching slot of the first clamping block. The anti-loosening side plates on both sides of the pushing and locking plate expand outward elastically under the action of the compression spring, and fit tightly with the inner wall of the slot to form a mechanical limit, completing the second-level mechanical locking and anti-loosening. Finally, take the Velcro cable tie, fix both ends to the preset fixing points in the middle of the pushing handle and the middle of the segmented insulating rod, respectively, and wrap it around the connection between the rod and the handle 2-3 times and tighten it. The wrapping direction is opposite to the force direction of the handle. The cable tie should not be displaced when the hand is lightly pulled and the pushing handle cannot swing, so as to achieve the three-level anti-loosening synergy of pawl locking, mechanical locking, and binding reinforcement.

[0026] Furthermore: The specific operational steps for the diversion process and real-time monitoring in S4 are as follows:

[0027] S4.1: After confirming that the three-level anti-loosening lock is not loose and that the first clamping block and the second clamping block are tightly attached to the wire, start the current diversion operation. The current diversion current sensing unit collects the current data of the current diversion copper busbar in real time. The data is refreshed every 5 seconds. The current fluctuation coefficient is accurately calculated by the formula. When it is greater than the preset current fluctuation coefficient, the sound and light warning unit issues a yellow warning. The operator must immediately check the wire contact status and clamping firmness, and at the same time observe whether the clamping force data is stable.

[0028] S4.2: When the current is ≥300A, which is the current warning threshold, a red warning will be issued. The current circuit must be cut off and the operation stopped immediately. The cause of the overload must be investigated and dealt with before restarting. During the operation, the clamping force sensing unit continuously monitors the clamping force. If the clamping force drops below 0.8F due to wire vibration or environmental disturbance, the audible and visual warning unit will issue a warning simultaneously. At this time, press the push handle slowly to replenish the pressure. During the replenishment process, the pawl assembly remains locked in one direction to prevent the rotating plate from loosening in the opposite direction until the clamping force is restored to the F range and the data is stable. During the operation, it is strictly forbidden to touch the clamping block, wire contact parts and current-conducting copper busbar. Operators must maintain a safe distance throughout the operation to avoid the risk of electric shock.

[0029] The formula for calculating the current fluctuation coefficient in S4 is as follows:

[0030]

[0031]

[0032] in, The maximum real-time current within 5 seconds. This is the minimum real-time current during the same period. This represents the average current during that period. Here, n represents the current fluctuation coefficient, and n is the number of data acquisitions within 5 seconds.

[0033] The present invention has the following beneficial effects:

[0034] 1. Enhanced anti-loosening stability and adaptability to complex working environments: By adopting a three-level anti-loosening synergistic structure of ratchet and ratchet locking, mechanical limit of push-locking plate, and Velcro strap binding, combined with buffer spring elasticity control, the anti-loosening torque is effectively improved, far exceeding the existing device's anti-loosening capacity of ≤50N·m. It can resist the risk of loosening under harsh working conditions such as strong winds in mountainous areas and working vibrations, and avoid the problem of failure of a single anti-loosening structure. At the same time, an emergency unlocking control rope and auxiliary pull rod structure are added to solve the defects of the existing device's cumbersome unlocking operation and lack of redundant design, so as to achieve rapid unlocking and emergency handling, and significantly shorten the operation time.

[0035] 2. Adaptable and flexible, accommodating multiple wire specifications and complex scenarios: The design of two clamping blocks for center alignment and the wave-shaped anti-slip texture of the elastic conductive sheet enable adaptive clamping of wires from thin wires below 10mm² to thick wires above 200mm². This avoids positioning deviation and avoids damage to the wire insulation layer and slippage risk through the elastic fit. At the same time, the segmented insulating rod design allows for quick assembly and disassembly of ≥3 units through hexagonal quick-release buckles. The single-segment rod body avoids the problem of inconvenience in carrying existing one-piece or long rod bodies, making it suitable for mountain climbing and complex space operations. Combined with the lightweight characteristics of carbon fiber reinforced epoxy resin material, it improves the accuracy and flexibility of operation and makes it easy to align the splicing position.

[0036] 3. Dual monitoring system to ensure operational safety and success rate: Through clamping force threshold control and real-time monitoring, the system automatically issues an early warning and can replenish pressure when the clamping force drops below the preset value, ensuring clamping stability. At the same time, by using the current fluctuation coefficient formula and average value calculation, the system accurately captures the current fluctuation pattern and promptly identifies problems such as poor contact and wire overload, avoiding operation failure due to abnormal circuit continuity. In addition, the dual monitoring and audible and visual early warning linkage realize full-process visualization of the operation status, significantly reducing the risk of electric shock and equipment damage, improving the success rate of live-line work, and reducing power outage time.

[0037] 4. Optimize materials and structure to balance safety and durability: The insulating rod is made of carbon fiber reinforced epoxy resin composite material and coated with a superhydrophobic anti-flashover coating. This ensures insulation performance and adapts to complex working environments such as humid and dusty conditions, preventing insulation attenuation. The clamping block is embedded with a ≥150mm² current-conducting copper busbar and a beryllium bronze silver-plated elastic conductive sheet to reduce contact resistance, reduce heat generation, and improve conductivity stability and durability.

[0055] Please see the appendix Figure 1-8 The present invention provides an embodiment 2: a method of using a push-type adaptive anti-loosening rapid drainage device, comprising the following steps:

[0056] S1: Preparation and assembly before use: Check the segmented insulating rod unit, the push-to-lock current-guiding mechanism 2, the anti-loosening mechanism 3, the dual monitoring and early warning mechanism, the current-guiding copper busbar, the elastic conductive sheet, and other components. Check that the carbon fiber rod body, the superhydrophobic anti-flashover coating, and the beryllium bronze silver-plated elastic conductive sheet anti-slip texture are all intact. Ensure that all hinge points are adequately lubricated and that the emergency unlocking control rope 14 is normal. Connect the insulating rod unit through the hexagonal quick-release buckle, fix the emergency unlocking control rope 14 to the auxiliary pull rod 13, start the monitoring and early warning mechanism, calibrate the sensor unit, set various thresholds, and debug the sound and light early warning unit to ensure normal operation and electrical connection.

[0057] S2: Target wire positioning and initial clamping: Hold the bottom of the segmented insulating rod, adjust the angle so that the two clamping blocks are aligned with the target drain wire and placed in the center, slowly press the push handle 21, and drive the rotating plate 22 to rotate around the first strip-shaped through hole 5 through the transmission link 23, drive the second clamping block 25 to move towards the first clamping block 24, observe the clamping force sensing unit data, and stop pushing when the set pre-tightening threshold is reached to complete the pre-clamping;

[0058] The specific steps for target wire positioning and initial clamping in S2 are as follows:

[0059] S2.1: The operator holds the segmented insulating rod at the bottom 1 / 3 with both hands, maintaining a safe distance between the body and the work area. The operator slowly adjusts the angle and height of the rod to ensure that the first clamping block 24 and the second clamping block 25 are precisely aligned with the target lead wire. The operator ensures that the lead wire is centered on the first clamping block 24 and the second clamping block 25, with uniform gaps on both sides. Taking advantage of the lightweight characteristics of the carbon fiber reinforced epoxy resin rod, the operator smoothly controls the first clamping block 24 and the second clamping block 25 to move closer to the lead wire, controlling the initial distance to 5-10cm and gradually fine-tuning the distance to avoid the clamping blocks directly colliding with the lead wire insulation layer and causing damage.

[0060] S2.2: Then, press the push handle 21 down slowly and evenly. The transmission link 23 drives the rotating plate 22 to rotate smoothly around the first strip-shaped through hole 5, which drives the second clamping block 25 to slowly move closer to the first clamping block 24 fixed on the connecting plate 7. During the process, keep a close eye on the sound and light warning unit display module in the middle of the rod and observe the real-time data fed back by the clamping force sensing unit. When the value reaches the preset pre-tightening threshold, stop pushing immediately. At this time, the beryllium bronze silver-plated elastic conductive sheet with wavy anti-slip texture initially adheres to the wire, completing the pre-clamping positioning and preparing for subsequent multiple anti-loosening locking.

[0061] S3: Multiple anti-loosening locking operation: After pre-clamping, slowly press the push handle 21. The rotating plate 22 drives the coaxial ratchet 34 to rotate synchronously. The pawl 33 engages with the ratchet 34 under the action of the buffer spring 12 to achieve one-way locking. The second clamping block 25 drives the push locking plate 31 to embed into the first clamping block 24 slot 10 to complete the second-level mechanical locking. Finally, fix the two ends of the Velcro strap 32 to the push handle 21 and the middle of the rod, wrap it 2-3 times and tighten it to achieve the third-level anti-loosening reinforcement.

[0062] The specific operating steps for the multiple anti-loosening locking operation in S3 are as follows:

[0063] S3.1: After pre-clamping, keep your hand steady and press the push handle 21 slowly and evenly, controlling the force evenly to avoid impact, so that the rotating plate 22 rotates smoothly around the first strip-shaped through hole 5. The ratchet 34, which is fixed coaxially with the rotating plate 22, rotates synchronously. Under the elastic thrust of the buffer spring 12, the pawl 33 automatically and precisely engages with the tooth groove of the ratchet 34 to achieve one-way locking to prevent the rotating plate 22 from loosening in the opposite direction. After locking, check the status by visual observation and gently shaking the push handle 21 to ensure that the compression of the buffer spring 12 is within the range of 2-5mm, and that there is no loosening or abnormal noise in the engagement.

[0064] S3.2: Continue to fine-tune the pressing handle until the feedback value of the clamping force sensing unit reaches the preset F standard, which is 50-150N. At this time, the second clamping block 25 simultaneously drives the pushing and locking plate 31 to accurately embed into the matching slot 10 of the first clamping block 24. The anti-loosening side plates 8 on both sides of the pushing and locking plate 31 expand outward elastically under the action of the compression spring 9, and tightly fit with the inner wall of the slot 10 to form a mechanical limit, completing the second-level mechanical locking and anti-loosening. Finally, take the Velcro cable tie 32, fix the two ends to the preset fixing points in the middle of the pushing handle 21 and the middle of the segmented insulating rod, respectively, and wrap it around the connection between the rod and the handle 2-3 times and tighten it. The wrapping direction is opposite to the force direction of the handle. The cable tie should not be displaced when the hand is lightly pulled and the pushing handle 21 cannot swing, so as to achieve the three-level anti-loosening synergy of pawl 33 locking, mechanical locking, and binding reinforcement.

[0065] S4: Current diversion operation and real-time monitoring: After confirming the anti-loosening lock, the current diversion operation is started. The current diversion current sensing unit collects the current data of the current diverting copper busbar in real time and calculates the current fluctuation coefficient. When it is greater than the preset current fluctuation coefficient, the sound and light warning unit issues a yellow warning. When the current is greater than the current diversion current warning threshold, a red warning is issued and the operation is stopped immediately. During the operation, the clamping force sensing unit continuously monitors. If the clamping force drops below 0.8F, the pressure is replenished to the preset clamping force range by pushing the handle 21.

[0066] The specific steps for drainage operations and real-time monitoring in S4 are as follows:

[0067] S4.1: After confirming that the three-level anti-loosening lock is not loose and that the first clamping block 24 and the second clamping block 25 are tightly attached to the wire, start the current diversion operation. The current diversion current sensing unit collects the current data of the current diversion copper busbar in real time. The data is refreshed every 5 seconds. The current fluctuation coefficient is accurately calculated by the formula. When it is greater than the preset current fluctuation coefficient, the sound and light warning unit issues a yellow warning. The operator must immediately check the wire contact status and clamping firmness, and at the same time observe whether the clamping force data is stable.

[0068] S4.2: When the current is ≥300A, which is the current warning threshold, a red warning will be issued. The current circuit must be cut off and the operation stopped immediately. The cause of the overload must be investigated and dealt with before restarting. During the operation, the clamping force sensing unit continuously monitors the clamping force. If the clamping force drops below 0.8F due to wire vibration or environmental disturbance, the audible and visual warning unit will issue a warning simultaneously. At this time, press the push handle 21 slowly to replenish the pressure. During the replenishment process, the pawl 33 component remains locked in one direction to prevent the rotating plate 22 from loosening in the opposite direction until the clamping force is restored to the F range and the data is stable. During the operation, it is strictly forbidden to touch the clamping block, wire contact parts and current-conducting copper busbar. Operators must maintain a safe distance throughout the operation to avoid the risk of electric shock.

[0069] The formula for calculating the current fluctuation coefficient in S4 is as follows:

[0070]

[0071]

[0072] in, The maximum real-time current within 5 seconds. This is the minimum real-time current during the same period. This represents the average current during that period. Here, n represents the current fluctuation coefficient, and n is the number of data acquisitions within 5 seconds.

[0073] S5: Operation Completion and Unlocking / Disassembly: After the drainage operation is completed, untangle the wrapped Velcro straps 32, pull the emergency unlocking control rope 14 at the bottom of the insulating rod, and drive the pawl 33 to overcome the elastic force of the buffer spring 12 and disengage from the tooth groove of the ratchet 34 through the auxiliary pull rod 13. After releasing the one-way lock, slowly release the push handle 21, so that the transmission link 23 drives the rotating plate 22 to rotate in the opposite direction. The second clamping block 25 moves away from the first clamping block 24, and the push locking plate 31 is pressed to disengage from the slot 10 to complete the mechanical unlocking. Finally, sort and store each component.

[0074] An embodiment 3 of this invention is provided below: The specific implementation process of this invention will be described in detail below, taking into account the 10kV distribution network capacity expansion operation scenario of Jinlong Paper Industry Co., Ltd. (conductor specifications: 150mm² aluminum core insulated conductor; operating environment: hilly terrain surrounding the factory area).

[0075] 1. Device assembly and commissioning

[0076] The operators arrived at the work site carrying the disassembled three sections of the insulating rod and all components. They quickly assembled the insulating rod using hexagonal quick-release clips, calibrated the clip fit after assembly, confirming it reached 96.25%, meeting the accuracy requirements. The emergency unlocking control rope was then placed along the rod's slots and fixed to the bottom, and its smooth, unobstructed movement was checked. The dual monitoring and early warning mechanism was activated, the sensor unit was calibrated, and the clamping force threshold was set to 100N (compatible with 240mm² wires), the pre-tightening threshold to 60N, and the lower limit threshold to 80N. The current warning threshold was set to 300A, and the fluctuation threshold to 5%. A short press of the test button confirmed that the audible and visual warning unit was functioning correctly.

[0077] 2. Conductor positioning and pre-clamping

[0078] The operator holds the bottom third of the insulating rod with both hands, maintaining a safe distance (≥1.5m) from the work area. Taking advantage of the rod's lightweight nature, the operator slowly adjusts the angle and height to align the two clamping blocks with the newly added 240mm² target conductor, ensuring the conductor is centered between the two clamping blocks with uniform gaps on both sides (error 1mm). The initial distance between the clamping blocks and the conductor is controlled at 8cm, and the blocks are smoothly brought closer to the conductor to avoid collision damage to the insulation layer. The operator slowly presses the push handle, which drives the rotating plate to rotate around the first through hole via the transmission linkage, driving the second clamping block to move towards the first clamping block. The operator observes the clamping force sensing unit data in real time. When the value reaches the 60N pre-tightening threshold, the operator stops pushing. At this point, the wavy anti-slip texture of the elastic conductive sheet initially adheres to the conductor, completing the pre-clamping positioning.

[0079] 3. Multiple anti-loosening locking mechanisms

[0080] Continue pressing the push handle at a constant speed. The rotating plate drives the coaxial ratchet to rotate synchronously. Under the action of the buffer spring (x=3mm, F=21N), the pawl precisely engages with the ratchet tooth groove to achieve one-way locking. Gently shake the push handle to check for looseness and abnormal noise. Continue to fine-tune the pressing until the clamping force reaches the standard threshold of 100N. At this time, the second clamping block drives the push locking plate to embed into the first clamping block slot. The anti-detachment side plate expands and fits into the slot under the action of the compression spring. The clamping force data is stable at 98-102N (deviation ≤±3N), completing the second-level mechanical locking. Finally, fix both ends of the Velcro cable tie to the middle of the push handle and the preset fixing point of the insulating rod, wrap it around the connection 3 times and pull it tight. There is no displacement when you pull it lightly, achieving three-level anti-loosening synergy and resisting gusts of wind interference.

[0081] 4. Traffic diversion operations and real-time monitoring

[0082] When the diversion operation is started, the diversion current sensing unit refreshes the data every 5 seconds. The current values ​​collected within 5 seconds are 220A, 225A, 222A, 223A, and 224A, respectively. The current fluctuation is smooth, and the fluctuation amplitude is far less than the preset threshold of 5%. There is no warning prompt. During the operation, a sudden gust of wind of 7m / s is encountered. The clamping force sensing unit feedback value drops to 82N (close to the lower limit threshold). The audible and visual warning unit issues a yellow warning. The operator slowly applies pressure to 100N. During the pressure application process, the pawl assembly locks in one direction without any reverse loosening, and the clamping force returns to stability.

[0083] 5. Unlock disassembly and storage

[0084] The diversion operation is completed (12 minutes, 8 minutes shorter than the existing device). First, untie the Velcro cable ties, then pull the emergency unlocking control rope at the bottom of the insulating rod. This will cause the pawl to overcome the spring force of the buffer spring and disengage from the ratchet tooth groove. Slowly release the push handle. The transmission linkage will drive the rotating plate to rotate in the opposite direction. The second clamping block will move away from the first clamping block. The push locking plate will be pressed and disengaged from the slot, completing the unlocking. Disassemble the insulating rod using the hexagonal quick-release buckle. Wipe the superhydrophobic coating of the rod body, the contact surface of the clamping block, and the elastic conductive sheet with a dry cloth to remove surface dust and wire residue. Sort and store the components, and tidy up the wound emergency unlocking control rope to avoid knots.

[0085] The entire process of diversion, connection, and dismantling took 12 minutes, which is 60% shorter than the existing equipment operation time (30 minutes). Combined with other operation links, the total power outage time was controlled within 86 minutes, meeting Jinlong Paper's requirement of "power outage ≤ 100 minutes".

[0086] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

S5: Operation completion and unlocking / disassembly: After the drainage operation is completed, untangle the wrapped Velcro straps (32), pull the emergency unlocking control rope (14) at the bottom of the insulating rod, and drive the pawl (33) to overcome the elastic force of the buffer spring (12) and disengage from the ratchet (34) tooth groove through the auxiliary pull rod (13).

Finally, sort and store each component.

8. The method of claim 7, wherein the cross arm preform is used for repairing a 10 kV line break under severe weather conditions. The specific steps for positioning and initially clamping the target wire in S2 are as follows: S2.1: The operator holds the bottom 1 / 3 of the segmented insulating rod with both hands, maintaining a safe distance between the body and the work area, and slowly adjusts the angle and height of the rod so that the first clamping block (24) and the second clamping block (25) are precisely aligned with the target guide wire, ensuring that the wire is in the center of the first clamping block (24) and the second clamping block (25) with uniform gaps on both sides. With the help of the lightweight characteristics of the carbon fiber reinforced epoxy resin rod, the operator smoothly controls the first clamping block (24) and the second clamping block (25) to move closer to the wire, controlling the initial distance to 5-10cm, and gradually fine-tuning the distance to avoid the clamping blocks directly colliding with the wire insulation layer and causing damage. S2.2: Then press down the push handle (21) slowly and evenly. Drive the rotating plate (22) to rotate smoothly around the first strip-shaped through hole (5) through the transmission link (23). Drive the second clamping block (25) to slowly move towards the first clamping block (24) fixed on the connecting plate (7). During the process, keep a close eye on the sound and light warning unit display module in the middle of the rod and observe the real-time data fed back by the clamping force sensing unit. When the value reaches the preset pre-tightening threshold, stop pushing immediately. At this time, the wave-shaped anti-slip texture of the beryllium bronze silver-plated elastic conductive sheet is initially attached to the wire, completing the pre-clamping positioning and preparing for subsequent multiple anti-loosening locking.

9. The method for emergency repair of a 10kV line breakage under severe weather conditions using a crossarm pre-construction as described in claim 7, characterized in that... The specific operation steps of the multiple anti-loosening locking operation in S3 are as follows: S3.1: After pre-clamping, keep your hand steady and press the push handle (21) slowly and evenly, control the force evenly to avoid impact, drive the rotating plate (22) to rotate smoothly around the first strip through hole (5), and the ratchet (34) fixed coaxially with the rotating plate (22) rotates synchronously. Under the elastic thrust of the buffer spring (12), the pawl (33) automatically and precisely meshes with the tooth groove of the ratchet (34) to achieve one-way locking to prevent the rotating plate (22) from loosening in the opposite direction. After locking, check the status by visual observation and light shaking of the push handle (21) to ensure that the compression of the buffer spring (12) is within the range of 2-5mm, and that there is no loosening or abnormal noise in the meshing. S3.2: Continue to fine-tune the pressing handle until the feedback value of the clamping force sensing unit reaches the preset F standard, which is 50-150N. At this time, the second clamping block (25) synchronously drives the pushing and locking plate (31) to accurately embed into the matching slot (10) of the first clamping block (24). The anti-loosening side plates (8) on both sides of the pushing and locking plate (31) expand outward elastically under the action of the compression spring (9), and fit tightly with the inner wall of the slot (10) to form a mechanical limit, thus completing the second-level mechanical locking and anti-loosening. Finally, take the Velcro cable tie (32), fix the two ends to the preset fixing points in the middle of the pushing handle (21) and the middle of the segmented insulating rod, respectively, and wrap it around the connection between the rod and the handle 2-3 times and tighten it. The wrapping direction is opposite to the force direction of the handle. The cable tie is pulled lightly by hand without displacement and the pushing handle (21) cannot swing, thus realizing the three-level anti-loosening coordination of pawl (33) locking, mechanical locking, and binding reinforcement.

10. The method for emergency repair of a 10kV line breakage under severe weather conditions using a crossarm pre-construction as described in claim 7, characterized in that... The specific operational steps for the drainage process and real-time monitoring in S4 are as follows: S4.1: After confirming that the three-level anti-loosening lock is not loose and that the first clamping block (24) and the second clamping block (25) are tightly attached to the wire, start the current diversion operation. The current diversion current sensing unit collects the current data of the current diversion copper bus in real time. The data is refreshed every 5 seconds. The current fluctuation coefficient is accurately calculated by the formula. When it is greater than the preset current fluctuation coefficient, the sound and light warning unit issues a yellow warning. The operator must immediately check the wire contact status and clamping firmness, and simultaneously observe whether the clamping force data is stable. S4.2: When the current is ≥300A, i.e. the current warning threshold, a red warning is issued. The current circuit must be cut off and the operation stopped immediately. The cause of the overload must be investigated and dealt with before restarting. During the entire operation, the clamping force sensing unit continuously monitors the clamping force. If the clamping force drops below 0.8F due to wire vibration or environmental disturbance, the sound and light warning unit will issue a warning simultaneously. At this time, press the push handle (21) slowly to replenish the pressure. During the replenishment process, the pawl (33) component remains locked in one direction to prevent the rotating plate (22) from loosening in the opposite direction until the clamping force is restored to the F range and the data is stable. During the operation, it is strictly forbidden to touch the clamping block, the wire contact part and the current guiding copper busbar. The operator must maintain a safe distance throughout the operation to avoid the risk of electric shock. The formula for calculating the current fluctuation coefficient in S4 is as follows: wherein, is the real-time maximum current in 5 seconds, is the real-time minimum current in the same period, is the average current in the period, is the current fluctuation coefficient, and n is the number of data collection in 5 seconds.
