Description

Technical Field

[0001] This application belongs to the field of electrical wire protection, and in particular relates to a device and operating method for preventing accidental contact with live conductors in power transmission and distribution lines. Background Technology

[0002] In routine maintenance, defect elimination, aging renovation, insulator replacement, and hardware installation and removal operations on power transmission and distribution lines, situations commonly arise where double-circuit lines on the same tower, multiple-circuit lines are mixed on the same structure, new and old lines run parallel to each other, and adjacent live lines cross over each other. Workers are highly susceptible to accidents due to factors such as obstructed vision, strong ambient light, poor visibility at night, fatigue, misjudgment, and lack of experience among new employees. These accidents can easily lead to dangerous situations like electric shock, falls from heights, and line short-circuit tripping. These are the most frequent and deadliest safety hazards in power line operations.

[0003] Currently, the industry's methods for preventing accidental contact are mainly divided into three categories: (1) Manual safety briefing + dedicated personnel monitoring: This relies entirely on manual control and has problems such as blind spots in monitoring, negligence in monitoring, obstruction of vision, and delayed response, making it impossible to achieve 24-hour real-time active protection; (2) Hanging warning signs and colorful flags: This is only a passive visual prompt, without distance sensing, alarm, or physical isolation, resulting in poor warning effect and inability to restrain personnel from accidentally touching the boundary; (3) Simple insulating shielding blankets and temporary barriers: These are not firmly fixed, are easily shifted by wind, cannot adapt to the spacing of the wires, and have no early warning function. They can only provide partial shielding and cannot achieve full-area, intelligent protection against accidental contact.

[0004] Existing technologies protect workers through passive warnings and simple shielding methods, but these methods lack distance detection, liveness detection, and audible and visual alarms. Workers are not alerted when they approach live conductors at near-dangerous distances, making it impossible to prevent accidental contact. Furthermore, the lack of rigid insulation and boundary limiting structures allows workers' arms, tools, and ropes to easily exceed safe distances and touch live conductors, making real-time intervention impossible and resulting in extremely low reliability. In addition, existing devices are mostly of fixed specifications, unable to adapt to different conductor spacings, voltage levels, and arrangement patterns, leading to poor on-site adaptability. Moreover, traditional temporary insulation shielding structures lack dedicated quick-fixing mechanisms, resulting in time-consuming installation at heights, swaying in the wind, displacement, and detachment, leading to a high probability of protection failure. Summary of the Invention

[0005] The purpose of this application is to overcome the defects in the prior art and provide a device and operating method for preventing accidental contact with live conductors in power transmission and distribution lines.

[0006] This application provides a device for preventing accidental contact with live conductors in power transmission and distribution lines, comprising:

[0007] An adaptive conductor quick-locking mechanism is located on the back of the foldable insulated main frame to clamp conductors or crossarms and generate clamping force.

[0008] The foldable insulating main frame includes a skeleton and multiple foldable hinges. One end of the skeleton is connected to the adaptive wire quick-locking mechanism, and the other end of the skeleton is connected to the edge fixing points of the foldable hinges and the fan-shaped insulating barrier, respectively, for transmitting and distributing the clamping force to the foldable hinges and the fan-shaped insulating barrier.

[0009] The fan-shaped insulating barrier is attached to the inside of the foldable insulating main frame, and its edge fixing points are connected to the skeleton, so as to be tensioned to form a flat and continuous insulating surface when receiving the clamping force.

[0010] The infrared distance sensing sound and light warning module has its infrared probe installed on the foldable insulated main frame. It is used to maintain a predetermined detection direction and detection field of view when the folding hinge is locked and the fan-shaped insulating barrier is tensioned.

[0011] Optionally, the inner side of the adaptive wire quick-locking mechanism is lined with an anti-slip insulating rubber pad.

[0012] Optionally, the adaptive wire quick-locking mechanism is an adjustable elastic clamp.

[0013] Optionally, the foldable insulated main frame is made of high-strength epoxy glass fiber.

[0014] Optionally, the sector-shaped insulating barrier is made of thickened high-strength silicone rubber insulating cloth.

[0015] Optionally, the fan-shaped insulating barrier can shrink as the foldable insulating main frame is folded, and unfold synchronously as the foldable insulating main frame is unfolded, forming a continuous insulating surface without perforations after unfolding.

[0016] Optionally, the infrared distance sensing sound and light warning module includes a warning distance threshold and a danger distance threshold, the warning distance threshold corresponding to a first alarm intensity, the danger distance threshold corresponding to a second alarm intensity, and the second alarm intensity being greater than the first alarm intensity.

[0017] Optionally, the infrared probe is a set of multiple infrared diffuse reflection probes, which are evenly distributed around the foldable insulating main frame.

[0018] Optionally, all edges and corners of the foldable insulating main frame are rounded to eliminate stress concentration points in the foldable insulating main frame.

[0019] This application also provides an operation method for a device to prevent accidental contact with live conductors in power transmission and distribution lines, used to operate the aforementioned device, including:

[0020] Unfold the foldable insulating main frame so that the fan-shaped insulating barrier unfolds synchronously with the unfolding of the frame;

[0021] Move the unfolded foldable insulating main frame to the target conductor or crossarm, so that the adaptive conductor quick locking mechanism is aligned with the target conductor or crossarm.

[0022] An actuating force is applied to the adaptive wire quick-locking mechanism, causing it to clamp the target wire or crossarm. The clamping force generated by the clamping action is transmitted through the skeleton and distributed to the edge fixing points of the folding hinge and the fan-shaped insulating barrier, thereby locking the folding hinge and tensioning the fan-shaped insulating barrier. The infrared probe maintains a predetermined detection direction and detection field of view when the folding hinge is locked and the fan-shaped insulating barrier is tensioned.

[0023] The beneficial effects of this application are:

[0024] This application provides a device for preventing accidental contact with live conductors in power transmission and distribution lines, comprising: an adaptive conductor quick-locking mechanism disposed on the back of a foldable insulated main frame for clamping conductors or crossarms and generating clamping force; the foldable insulated main frame includes a skeleton and multiple foldable hinges, one end of the skeleton is connected to the adaptive conductor quick-locking mechanism, and the other end of the skeleton is connected to the edge fixing points of the foldable hinges and the fan-shaped insulating isolation barrier, respectively, for transmitting and distributing the clamping force to the foldable hinges and the fan-shaped insulating isolation barrier; the fan-shaped insulating isolation barrier is attached to the interior of the foldable insulated main frame, and its edge fixing points are connected to the skeleton, for being tensioned to form a flat and continuous insulating surface when receiving the clamping force; and an infrared distance sensing sound and light warning module, whose infrared probe is installed on the foldable insulated main frame, for maintaining a predetermined detection direction and detection field of view when the foldable hinges are locked and the fan-shaped insulating isolation barrier is tensioned. This application utilizes a foldable insulated main frame to transfer and distribute the clamping force to the folding hinge and the fan-shaped insulating barrier, causing them to be tensioned to form a flat and continuous insulating surface. In this state, the infrared distance sensing sound and light warning module maintains the predetermined detection direction and field of view. This solves the defects of existing technologies, such as the inability to restrain boundary crossing behavior due to the lack of physical isolation and limiting structure, the inability to avoid accidental collision risks due to the lack of active warning function, and the failure of protection due to unstable installation. It achieves integrated active protection of intelligent warning, physical isolation and boundary limiting. Attached Figure Description

[0027] Exemplary embodiments of the present disclosure will now be provided in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the various forms of disclosure should not be limited to the embodiments set forth in this application. Rather, the embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] This application provides a device for preventing accidental contact with live conductors in power transmission and distribution lines, which is applied in the field of safety protection tooling technology for power transmission and distribution lines. This application is used to solve the problems of existing protection methods for working in energized areas of power transmission and distribution lines being singular, having delayed early warning, lacking physical isolation, and being unreliable in protection.

[0029] The aforementioned device for preventing accidental contact with live conductors on power transmission and distribution lines integrates high-voltage inductive power detection, distance infrared sensing early warning, deployable insulation barrier, adaptive fast locking and fixing, and work area limit protection functions. It achieves early warning of dangerous approach, accurate identification of live status, and physical isolation to prevent accidental contact, thus comprehensively improving the safety protection level of high-altitude operations on power transmission and distribution lines.

[0030] Please refer to Figure 1 As shown, the device for preventing accidental contact with live conductors in power transmission and distribution lines comprises seven core functional modules: a foldable insulated protective main frame, a high-voltage live induction detection module, an infrared distance sensing audible and visual early warning module, an adaptive conductor quick-locking mechanism 1, a fan-shaped insulated isolation barrier 3, a work boundary limit stop bar, and a portable power supply and control module. The device uses lightweight insulated material and a foldable telescopic structure, allowing for quick clamping and fixing to pole crossarms, conductor hanging points, and hardware positions. The high-voltage induction module identifies the live state of the conductor, the infrared sensor detects the intrusion distance of personnel and tools, providing real-time audible and visual early warnings. Simultaneously, a large-area insulated barrier is deployed to form physical isolation, and the limit stop bar delineates the safe work boundary, achieving triple protection against accidental contact through intelligent early warning, physical isolation, and boundary limit.

[0031] Adaptive wire quick-locking mechanism 1: Located on the back of the foldable insulated main frame 2, it is used to clamp the wire or crossarm and generate clamping force.

[0032] The adaptive wire quick-locking mechanism 1 consists of multiple adjustable elastic clamp locking components mounted on the back of the device. It can quickly and adaptively lock and fix wires of different diameters, crossarms, angle steel, and hardware hanging rings without bolts or auxiliary tools. A single person can complete the high-altitude installation and fixing in just 10 seconds. The locking components have built-in anti-slip insulating rubber pads, ensuring a stable grip without slippage or damage to the wires and hardware. It also provides strong stability against wind and swaying, ensuring no deviation or detachment during high-altitude operations.

[0033] The adaptive wire quick-locking mechanism 1 is located on the back of the foldable insulated main frame 2. Its main function is to generate clamping force by clamping the wire or crossarm, thereby firmly fixing the entire device in the working position.

[0034] For example, during high-altitude maintenance of power transmission and distribution lines, workers can directly clamp the adaptive conductor quick-locking mechanism 1 onto the tower crossarm or conductor. The clamping force generated by its elastic clamping structure stabilizes the device, avoiding the cumbersome and time-consuming drawbacks of traditional bolt fixing methods. Furthermore, the inner side of the adaptive conductor quick-locking mechanism 1 is lined with an anti-slip insulating rubber pad to increase the coefficient of friction, preventing slippage under wind or vibration, and protecting the conductor and fitting surfaces from damage.

[0035] The foldable insulated main frame 2 includes a skeleton and multiple folding hinges.

[0036] One end of the skeleton is connected to the adaptive wire quick-locking mechanism 1, and the other end of the skeleton is connected to the edge fixing points of the folding hinge and the fan-shaped insulating barrier 3, respectively, for transmitting and distributing the clamping force to the folding hinge and the fan-shaped insulating barrier 3.

[0037] The foldable insulated main frame 2 is made of high-strength epoxy fiberglass insulation material, with an insulation level meeting the 500kV high-voltage operation safety standard. It features zero conductivity, high strength, aging resistance, and wind and corrosion resistance. The frame adopts a multi-segment hinged folding structure, which can be radially folded for storage and unfolded into a neat three-dimensional protective frame when unfolded. When folded, it is a flat strip, significantly reducing its volume for easy portability and transport, and making it easy to carry at heights. All edges and corners of the frame are rounded to avoid scratching wires, hardware, and personnel.

[0038] The foldable insulated main frame 2 is the supporting structure of the entire device. One end of its frame is connected to the adaptive conductor quick-locking mechanism 1, and the other end is connected to the edge fixing point of the folding hinge and the sector-shaped insulating barrier 3. When the adaptive conductor quick-locking mechanism 1 clamps the conductor or crossarm and generates a clamping force, this clamping force is transmitted through the frame and distributed to the folding hinge and the sector-shaped insulating barrier 3, thereby maintaining a stable mechanical structure of the entire device in the unfolded state.

[0039] For example, when the operator attaches the adaptive conductor quick-locking mechanism 1 to the crossarm, the clamping force is transmitted through the frame, causing the folding hinge to lock, while the fan-shaped insulating barrier 3 is tensioned, forming a stable protective unit.

[0040] In addition, all edges and corners of the foldable insulating main frame 2 are rounded to eliminate stress concentration points and prevent sharp corners from scratching wires, hardware and workers, thus improving safety.

[0041] The fan-shaped insulating barrier 3 is attached to the interior of the foldable insulating main frame 2, and its edge fixing point is connected to the skeleton, so as to be tensioned to form a flat and continuous insulating surface when receiving the clamping force.

[0042] The fan-shaped insulating barrier 3 is made of thickened, high-strength silicone rubber insulating cloth. When unfolded, it forms a large-area continuous insulating barrier surface, completely covering the hazardous area where live wires are being worked. The barrier can be folded and retracted with the frame. When unfolded, it has no gaps or blind spots, effectively preventing workers' limbs and tools from directly touching live wires, forming a rigid physical protective barrier and completely eliminating accidental contact accidents.

[0043] The sector-shaped insulating barrier 3 is attached inside the foldable insulating main frame 2, with its edge fixing points connected to the skeleton. When the clamping force generated by the adaptive conductor quick-locking mechanism 1 is transmitted through the skeleton to the edge fixing points of the sector-shaped insulating barrier 3, the barrier is tensioned, thus forming a flat and continuous insulating surface. This insulating surface can completely cover the dangerous area of ​​the live conductor, serving as a physical isolation.

[0044] For example, when performing maintenance work near live conductors, the tensioned fan-shaped insulating barrier 3 can effectively prevent workers' limbs or tools from accidentally coming into contact with the live conductors. Even if workers make operational errors, they cannot cross the barrier to touch the live conductors, thus achieving physical safety protection.

[0045] The fan-shaped insulating barrier 3 can shrink as the foldable insulating main frame 2 is folded, and unfold synchronously as the foldable insulating main frame 2 is unfolded, forming a continuous insulating surface without holes after unfolding, ensuring that there are no blind spots in protection.

[0046] Infrared distance sensing sound and light warning module: Its infrared probe 4 is installed on the foldable insulated main frame 2, and is used to maintain the predetermined detection direction and detection field of view when the folding hinge is locked and the fan-shaped insulating isolation barrier 3 is tensioned.

[0047] The infrared distance sensing sound and light early warning module includes multiple sets of infrared diffuse reflection sensing probes, providing 360° full coverage of the working area, and preset two-level thresholds for safe early warning distance and danger alarm distance.

[0048] When workers, insulated tools, or lifting ropes approach the warning threshold range of a live conductor, the device automatically emits a high-frequency buzzer and a bright red and blue flashing light warning; when they approach the critical danger distance further, the alarm is upgraded to an urgent alarm, forcibly reminding workers and supervisors to stop operating beyond the boundary, thus achieving early prediction and proactive risk avoidance.

[0049] The sound and light module features high-brightness warning at night and high visibility in strong light environments, making it suitable for all-weather operation, including daytime, nighttime, rainy, and foggy conditions. The infrared sensor 4 of the infrared distance sensing sound and light warning module is mounted on the foldable insulated main frame 2. Its installation position and angle are designed so that the infrared sensor 4 can maintain its predetermined detection direction and field of view only when the folding hinge is locked and the fan-shaped insulating barrier 3 is tensioned. This is because the device's mechanical structure, after being fully unfolded and locked, forms a stable geometric configuration, ensuring that the detection direction of the infrared sensor 4 will not deviate due to device shaking or deformation, thus ensuring the accuracy of distance sensing.

[0050] For example, once the device is correctly installed and fully deployed, the infrared sensor 4 will face the work area at a preset angle. Once the workers or tools enter the warning distance range, the sound and light warning module will be activated immediately to issue an alarm and remind relevant personnel to pay attention to safety.

[0051] The infrared distance sensing audible and visual warning module includes a warning distance threshold and a danger distance threshold. The warning distance threshold corresponds to a first alarm intensity, and the danger distance threshold corresponds to a second alarm intensity, which is greater than the first alarm intensity. The first alarm intensity is a high-frequency buzzer combined with a bright red and blue flashing light, while the second alarm intensity is a more urgent alarm sound and a stronger flashing light, to forcibly remind operators and supervisors to stop operations beyond the designated area.

[0052] The aforementioned device for preventing accidental contact with live conductors in power transmission and distribution lines also integrates a high-voltage live induction detection module. This module is located inside the frame and uses a high-precision non-contact high-voltage induction sensor, which can detect the live state of the conductor in real time without contact and automatically distinguish between three working conditions: live operation, complete power outage, and residual induced current.

[0053] The sensor has a built-in signal amplification and recognition chip, strong resistance to environmental electromagnetic interference, and can identify live bodies of various voltage levels from 10kV to 500kV, eliminating false alarms and missed alarms; it automatically activates the early warning system after detecting a live state, and automatically goes into sleep mode to save energy in the event of a power outage.

[0054] The aforementioned device for preventing accidental contact with live conductors in power transmission and distribution lines is also equipped with work boundary limiting bars. These bars consist of multiple retractable insulated limiting bars that are hinged to the outside of the frame. When unfolded, they extend outward to delineate the safe work boundary range, rigidly restricting the range of limb extension and tool operation for workers, thus preventing accidental contact with live areas from a spatial perspective.

[0055] The extension length of the stop bar is freely adjustable, adapting to safety distance standards for different voltage levels, making it highly versatile.

[0056] The aforementioned device for preventing accidental contact with live conductors in power transmission and distribution lines is also equipped with a portable power supply and intelligent control module. It has a built-in rechargeable lithium battery pack and a low-power intelligent control motherboard, and features voltage detection, distance sensing, audible and visual graded early warning, sleep mode energy saving, and low battery reminder functions.

[0057] The portable power supply and intelligent control module supports USB fast charging and can work continuously for 72 hours on a single full charge, meeting the needs of long-term maintenance operations; it has a waterproof and dustproof structure, making it suitable for harsh working environments such as rain, snow, sandstorms, and sun exposure.

[0058] The aforementioned device for preventing accidental contact with live conductors in power transmission and distribution lines is also equipped with a charging waterproof interface and an anti-slip insulating locking pad. The charging waterproof interface is used to charge the built-in battery pack and prevent moisture intrusion. The anti-slip insulating locking pad is located inside the adaptive conductor quick locking mechanism 1 to enhance clamping friction and protect the conductor and fittings.

[0059] This device achieves the following technical effects:

[0060] Completely eliminate safety accidents caused by accidental contact with live wires. The triple protection mechanism provides a safety net at every level, both providing early warning of risks and physically blocking accidental contact paths and restricting work boundaries. This fundamentally solves the problems of blind spots in manual monitoring, delayed response, and ineffective warnings, achieving zero accidental contact safety protection.

[0061] It significantly improves the standardization and intelligence of high-altitude operations, replacing outdated passive protection methods such as traditional manual monitoring, colored flags, and warning signs, and realizes mechanized and intelligent proactive safety protection, which meets the State Grid's standardized operation requirements and enhances the line operation and maintenance safety management capabilities;

[0062] Reduce operational risks, reduce reliance on manpower, reduce dependence on dedicated personnel for full-time monitoring, reduce safety hazards caused by human negligence and fatigue monitoring, significantly reduce safety risks of high-risk line operations, and ensure the personal safety of operators and the stable operation of the power grid;

[0063] It boasts high operational efficiency, wide applicability, and quick and convenient installation and disassembly without taking up maintenance time or affecting normal work processes. It is suitable for all power transmission and distribution lines in both live and power outage conditions, making it highly versatile and practical. It also features a long service life, low maintenance costs, fully insulated, corrosion-resistant, and aging-resistant materials, a robust and impact-resistant structure, and the ability to be repeatedly used without frequent replacement of consumables, significantly reducing the maintenance costs of safety protection equipment.

[0064] This device addresses the major safety concerns of high-altitude operations on power transmission and distribution lines, such as large blind spots in manual monitoring, ineffective passive warnings, easy accidental contact with live conductors, and lack of physical isolation protection. It innovatively designs a four-fold safety protection system that combines intelligent live identification, distance-based early warning, physical insulation isolation, and spatial boundary limiting, completely overturning the traditional passive warning protection mode.

[0065] This device is lightweight, quick to assemble and disassemble, intelligent and reliable, and applicable in all weather conditions. It can proactively predict, warn, and isolate the entire operation process, eliminating serious safety accidents caused by accidental contact with live conductors at high altitudes from a hardware perspective. It significantly improves the safety, standardization, and intelligence of power transmission and distribution line operation and maintenance, and has extremely high engineering practical value and industry promotion prospects.

[0066] Please refer to Figure 2 As shown, this application also provides an operation method for a device to prevent accidental contact with live conductors in power transmission and distribution lines, including:

[0067] S201. Unfold the foldable insulating main frame 2 so that the fan-shaped insulating isolation barrier 3 unfolds synchronously with the unfolding of the frame.

[0068] Before carrying out high-altitude operations, the operator first takes out the device, which is in a folded and stored state. At this time, the foldable insulated main frame 2 is flat and strip-shaped, making it easy to carry and transport.

[0069] The operator holds a handheld device and manually pulls or pushes the hinged sections of the frame to unfold it radially, forming a regular three-dimensional protective frame. Since the fan-shaped insulating barrier 3 is attached to the interior of the foldable insulating main frame 2, and its edge fixing points are connected to the skeleton, the fan-shaped insulating barrier 3 unfolds synchronously with the frame when it is unfolded, changing from a folded / retracted state to an unfolded state, forming a large-area continuous insulating isolation surface that completely covers the hazardous area where live wires are operating.

[0070] The foldable insulated main frame 2 is made of high-strength epoxy fiberglass insulation material. The insulation level meets the safety standard for 500kV high-voltage operations. It is zero conductive, high-strength, aging-resistant, wind-resistant, and corrosion-resistant. All edges and corners of the frame are rounded and blunted to avoid scratching wires, hardware, and workers.

[0071] The fan-shaped insulating barrier 3 is made of thickened high-strength silicone rubber insulating cloth, which has good insulation performance and flexibility. It can be folded and contracted with the frame, and after unfolding, it forms a continuous insulating surface without holes, completely covering the dangerous area of ​​live wire operation, forming a rigid physical protective barrier.

[0072] S202. Move the unfolded foldable insulating main frame 2 to the target conductor or crossarm, so that the adaptive conductor quick locking mechanism 1 is aligned with the target conductor or crossarm.

[0073] After the frame is fully extended, the operator holds both sides of the frame and lifts the entire device smoothly to the target working position, i.e., the wire or crossarm to be installed. The adaptive wire quick-locking mechanism 1 on the back of the device consists of multiple sets of adjustable elastic clamp locking components. The operator needs to align this locking mechanism with the target wire, crossarm angle steel, or hardware hanging ring, so that its center line is aligned with the target object.

[0074] This adaptive wire quick-locking mechanism 1 can adapt to wires of different diameters, crossarm angle steel, and hardware hanging rings, achieving rapid alignment without prior adjustment of specifications. During movement, care should be taken to avoid collisions between the device and surrounding live parts, as all edges and corners of the frame are rounded to effectively reduce the risk of scratches.

[0075] S203. Apply an actuating force to the adaptive wire quick-locking mechanism 1 to clamp the target wire or crossarm. The clamping force generated by the clamping action is transmitted through the skeleton and distributed to the edge fixing points of the folding hinge and the fan-shaped insulating barrier 3, so that the folding hinge is locked and the fan-shaped insulating barrier 3 is tensioned. The infrared probe 4 maintains a predetermined detection direction and detection field of view in the state where the folding hinge is locked and the fan-shaped insulating barrier 3 is tensioned.

[0076] The operator presses or pushes the adaptive conductor quick-locking mechanism 1 by hand to apply actuation force to it, causing the elastic clamp locking assembly to close, thereby clamping the target conductor or crossarm.

[0077] This locking mechanism requires no bolts or auxiliary tools, and a single person can complete the high-altitude installation and fixation in 10 seconds.

[0078] The locking assembly has a built-in anti-slip insulating rubber pad, which ensures a stable clamping without slippage or damage to the wires and fittings. It also provides strong stability against wind and shaking, ensuring no deviation or detachment during high-altitude operations.

[0079] When the locking mechanism clamps, the resulting clamping force is transmitted through the frame and distributed to the edge fixing points of the folding hinge and the fan-shaped insulating barrier 3.

[0080] On the one hand, the clamping force locks the folding hinge, ensuring that the frame remains in the unfolded state without deformation;

[0081] On the other hand, the clamping force is transmitted to the edge fixing point of the fan-shaped insulating barrier 3, so that the barrier is tensioned and forms a flat and continuous insulating surface.

[0082] With the folding hinge locked and the fan-shaped insulating barrier 3 tensioned, the infrared probe 4 installed on the foldable insulating main frame 2 maintains the predetermined detection direction and field of view. This is because the mechanical structure of the device forms a stable geometric configuration after being fully unfolded and locked, ensuring that the detection direction of the infrared probe 4 will not deviate due to device shaking or deformation, thus ensuring the accuracy of distance sensing. At this time, the infrared distance sensing sound and light warning module starts to work normally. Multiple sets of infrared diffuse reflection sensing probes provide 360° full coverage detection of the work area, with preset two-level thresholds for safe warning distance and danger alarm distance. When workers, insulated tools, or lifting ropes approach the warning threshold range of live wires, the device automatically emits a high-frequency buzzer and a bright red and blue flashing light warning.

[0083] When the distance to the danger threshold is approached, an urgent alarm is triggered to forcefully remind the workers and supervisors to stop the operation beyond the boundary, thus enabling early prediction and proactive risk avoidance.

[0084] Meanwhile, the high-voltage live induction detection module detects the live status of the conductor in real time, automatically distinguishes between three operating conditions: live operation, complete power outage, and residual induced current. After detecting the live state, it automatically activates the early warning system, and automatically goes into sleep mode to save energy during power outage.

[0085] At this point, the device is installed and in operation, and workers can carry out maintenance work within the safe area defined by the sector-shaped insulating barrier 3 and the work boundary limit stop.

[0086] The above embodiments are provided to enable those skilled in the art to understand and apply this application. Those skilled in the art will readily make various modifications to the above embodiments and apply the general principles described herein to other embodiments without inventive effort. Therefore, this application is not limited to the above embodiments, and any improvements and modifications made to this application based on the disclosure thereof should be within the scope of protection of this application.
