[0027] The electric power construction protection fence is a key device to ensure the safety of electric power operations, and its type, technical specifications and safety standards are all strictly designed. Type classification: By material: Metal fence: Made of stainless steel, hot-dip galvanized steel pipe, etc., corrosion-resistant and high-strength, suitable for long-term fixed places such as substations and transmission lines. Plastic / FRP fence: Lightweight and easy to install, commonly used in temporary construction or mobile operation areas. Wooden fence: Mostly used for beautifying the environment or low-risk areas. By function: Protective fence: Isolate live equipment to prevent personnel from straying. Warning fence: Remind dangerous areas through signs. By structure: Fixed fence: Fixed by concrete foundation, with high stability. Movable fence: Designed for splicing or folding, suitable for temporary operations.

[0028] Core uses: Isolation and protection: Demarcate the construction area and prevent unauthorized personnel from entering. Equipment protection: Prevent equipment such as transformers and cables from being damaged or stolen. Isolation of dangerous areas: Isolate high-risk areas such as high-voltage areas. Safety warning: Remind risks through signs such as "High voltage danger".

[0029] Material requirements: Metal parts: Require hot-dip galvanized or stainless steel materials, rust-proof and durable. Insulating parts: Made of flame-retardant nylon or FRP, with a voltage withstand level matching the equipment. Stability design, fixed type: Embedded concrete foundation, wind resistance level ≥ 8. Movable type: Equipped with a weighted base or ground pier to prevent tipping.

[0030] Core Technical Requirements and Material Selection for Electric Power Construction Protection Fences, Insulation Performance: Material Application: Mainly use non-conductive materials such as plastics, rubbers, and fiberglass to block current conduction. For example, the perimeter fences of substations use insulated round or square pipes with red and white reflective paint coated on the surface to balance warning and safety. Scene Adaptation: Metal fences (steel, aluminum alloy) need to achieve indirect insulation through structural design or coatings and are applicable to areas that need to balance physical protection and conductive risks. Stability and Durability: Metal Fences: Steel (Q234-AF steel) is commonly used for temporary protective barriers, which are welded or bolted and have strong impact resistance; aluminum alloy fences are lightweight and corrosion-resistant and are suitable for long-term outdoor deployment. Non-Metal Fences: PVC / plastic fences are lightweight and easy to install, but have weak wind pressure resistance and are mostly used in low-voltage or non-core areas. Visibility and Warning: Color Specification: Red and white, yellow and black painted or reflective stickers meet the requirements of the "Safety Protection Manual for On-site Operations of Electric Power Enterprises" for sign visualization. Intelligent Warning: Electronic fences are linked with audible and visual alarms to enhance the active warning effect.

[0031] Application Scenarios and Technical Challenges, Typical Scenarios: Substation Perimeter: Mainly use electronic fences + AI recognition, combined with physical barriers and real-time alarms. Construction Sites: Temporary fences (red and white ropes + triangular flags) are combined with warning signs to demarcate the isolation area of live equipment. Existing Challenges, Environmental Adaptability: Non-metal fences are prone to aging in bad weather, and electronic fences may give false alarms. Maintenance Cost: The intelligent system needs to upgrade the algorithm regularly, and traditional fences need anti-corrosion treatment. The current technology of electric power construction protection fences has formed a dual-track system of "traditional physical protection + intelligent electronic protection". Material selection needs to balance safety and economy, structural design needs to comply with scene specifications, and intelligent technology significantly improves the active defense ability. In the future, with the application of composite materials and the optimization of AI algorithms, protection fences will evolve towards a more intelligent and environmentally friendly direction, further reducing the safety risks of electric power construction.

[0032] It is known that the existing patent discloses a telescopic fence for electric power construction safety protection, with the application number 202111392512.3, which includes support columns. At the top ends of both sides of the support columns, first movable connection shafts are installed. At the bottom ends of both sides of the support columns, second movable connection shafts are installed. A first protection frame is installed between the first movable connection shaft and the second movable connection shaft. A second protection frame is installed on the side of the first protection frame away from the support column. A first movable connection component is installed between the bottom ends of the first protection frame and the second protection frame. A second movable connection component is installed between the top ends of the first protection frame and the second protection frame. Protection plate components are installed on both the first protection frame and the second protection frame. A power mechanism is installed on the support column and is connected to the first protection frame. A fixing plate is installed at the bottom of the support column. Fixing bolts are symmetrically installed on the fixing plate, and the bottom ends of the fixing bolts are of a conical pointed structure. During use, through the interaction of the set support columns, first movable connection shafts, second movable connection shafts, first movable connection components, second movable connection components, and power mechanism, the first protection frame and the second protection frame can be better driven to move telescopically, so that during the use of the fence for electric power construction safety protection, it is convenient to better perform telescoping, thus facilitating people to better operate. And through the interaction of the set fixing plate and fixing bolts, during use, it is convenient to better position the fence, so as to ensure the stability of the fence during use, facilitate better safety protection operations, and thus facilitate better meeting people's usage requirements.

[0033] The power mechanism includes a driving motor. A power supply is installed above the driving motor, and both the power supply and the driving motor are installed inside the support column. The power supply is a rechargeable power supply, and a charging interface is installed on the outer side of the support column. A switch is installed on the top of the charging interface. A driving gear is installed at the bottom of the driving motor. First transmission gears are meshed and connected to both sides of the driving gear, and the first transmission gears are connected to the first protective frame. The first movable connection assembly includes a first connecting plate. Third movable connection shafts are symmetrically installed on the first connecting plate, and the two third movable connection shafts are respectively connected to the bottom ends of the first protective frame and the second protective frame. A moving pulley is installed at the bottom of the first connecting plate. The second movable connection assembly includes a second connecting plate. Fourth movable connection shafts are symmetrically installed on the second connecting plate, and the two fourth movable connection shafts are respectively connected to the top ends of the first protective frame and the second protective frame. A second transmission gear and a third transmission gear are installed below the fourth movable connection shaft. The second transmission gear is connected to the first protective frame, and the third transmission gear is connected to the second protective frame. First movable connection bars and second movable connection bars are installed on the top of the second connecting plate. The two ends of the first movable connection bar are respectively connected to the first movable connection shaft and the second connecting plate through movable shafts. The two ends of the second movable connection bar are respectively connected to the second connecting plate and the second protective frame through movable shafts. During use, first, the support column is fixedly installed through the interaction of the fixing plate and the fixing bolt. Then, the driving motor is started to drive the driving gear to rotate. The driving gear drives the first transmission gears. Under the interaction of the first transmission gears, the first movable connection shaft and the second movable connection shaft, the first protective frame is driven to move. When the first protective frame moves, the third transmission gear is driven to move under the action of the second transmission gear. Under the interaction of the third transmission gear, the third movable connection shaft and the fourth movable connection shaft, the second protective frame is driven to move. At the same time, the first connecting plate drives the moving pulley to roll, and the second connecting plate drives the first movable connection bar and the second movable connection bar to move, which can ensure the stability of the first protective frame and the second protective frame during movement, so that the first protective frame and the second protective frame can move and expand better, so that the fence for power construction safety protection can be expanded and contracted more conveniently during use, thus facilitating people to operate better.

[0034] The protective plate assembly includes a protective baffle. Connecting springs are evenly installed at the top and bottom of the protective baffle, and the protective baffle is connected to the first protective frame and the second protective frame through the connecting springs. A circular installation groove is formed in the middle of the protective baffle, a bell is installed inside the circular installation groove, and three reflective strips are installed on both sides of the circular installation groove. During use, through the set protective plate assembly, it can enable the first protective frame and the second protective frame to achieve better shielding during use. And under the action of the connecting springs, when the protective baffle is subjected to an external force, it can shake. The shaking of the protective baffle drives the bell to shake, causing the bell to make a sound, which can achieve a certain warning effect. And under the action of the reflective strips, it can play a more eye-catching effect, so as to improve the safety protection effect of the fence and ensure normal power construction operations. Working principle: During operation, first, through the interaction of the fixing plate and the fixing bolts, the support column is fixedly installed. Then, the driving motor is started to drive the driving gear to rotate. The driving gear drives the first transmission gear.

At the same time, the first connecting plate drives the moving pulley to roll, and the second connecting plate drives the first movable connection bar and the second movable connection bar to move, which can ensure the stability of the first protective frame and the second protective frame during movement, so that the first protective frame and the second protective frame can move and expand and contract better, so as to enable the fence for power construction safety protection to expand and contract better during use, thus facilitating people to operate better. In addition, through the set protective plate assembly, it can enable the first protective frame and the second protective frame to achieve better shielding during use. And under the action of the connecting springs, when the protective baffle is subjected to an external force, it can shake.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Embodiment 1

[0038] Referring to Figures 1-5 As shown, this embodiment provides a protective fence for electric power construction, including several frames 1. Adjacent frames 1 are connected by mounting cylinders 5 and pin shafts, and the edge is fixed by a bracket 6. The top of the bracket 6 extends into the mounting cylinder 5. A reinforcing plate 3 is fixedly connected inside the frame 1. Several upper rotating plates 2 are arranged on the top surface of the reinforcing plate 3, and several lower rotating plates 4 are arranged on the bottom surface of the reinforcing plate 3. The several upper rotating plates 2 and the several lower rotating plates 4 are arranged in one-to-one correspondence. When the upper rotating plate 2 or the lower rotating plate 4 rotates to be horizontally aligned with the frame 1, there is no gap between two adjacent upper rotating plates 2 or two adjacent lower rotating plates 4. Both sides of the bottom of the bracket 6 are respectively fixedly connected with a sleeve 7, and a plug rod 16 for inserting into the ground is installed inside the sleeve 7.

[0039] The frame 1 is hinged through the mounting cylinder 5 and the pin shaft, and the edge is fixed by the bracket 6. The top of the bracket 6 extends into the mounting cylinder 5 to enhance stability. The reinforcing plate 3 is internally provided with upper and lower rotating plates 4, which can be completely aligned with the frame 1 after rotation to eliminate the gap, thereby playing a certain role in preventing dust. And the plug rod 16 inside the sleeve 7 can be quickly inserted into the ground to improve the stability of the structure. The present invention allows for quick disassembly through pin shaft connection, adapts to different terrains and operation requirements, and forms a continuous barrier after the rotating plates are closed to prevent people or objects from passing through, improving safety; at the same time, the reinforcing plate 3 enhances the impact resistance of the frame 1 and improves the protection ability.

[0040] In a further optimized solution, a toothed plate 14 is slidably connected inside the reinforcing plate 3. One end of the toothed plate 14 is fixedly connected to the output end of a hydraulic cylinder 13, and the hydraulic cylinder 13 is fixedly connected to the inner wall of the reinforcing plate 3. Several first gears 15 are meshed with the side wall of the toothed plate 14. The several first gears 15 are respectively arranged corresponding to the several upper rotating plates 2 and the several lower rotating plates 4. A transmission shaft is fixedly connected to the center of the first gear 15, and both ends of the transmission shaft are respectively connected to the upper rotating plate 2 and the lower rotating plate 4 and can drive the upper rotating plate 2 and the lower rotating plate 4 to rotate. The toothed plate 14 is meshed with the first gear 15, and the transmission shaft is connected to the upper and lower rotating plates 4. By sliding the toothed plate 14 to drive the gear to rotate, the opening and closing of the rotating plates are controlled. By driving multiple groups of rotating plates with a single toothed plate 14, the linkage opening and closing are realized, with high operation efficiency, and the gear transmission ensures accurate positioning of the rotating plates and more reliable seamless closing.

[0041] For a further optimized solution, a connecting block 17 is fixedly connected to the side wall of the insertion rod 16. The end of the connecting block 17 extends out of the sleeve 7 and is fixedly connected to a pedal 9. An inverted L-shaped groove 8 is formed in the sleeve 7, and the connecting block 17 is adapted to the inverted L-shaped groove 8. The inverted L-shaped groove 8 restricts the movement track of the connecting block 17. When the pedal 9 is stepped on, the insertion rod 16 is inserted into the ground. The pedal 9 adopts the lever principle, which is more labor-saving, and a single person can complete the firming of the fence.

[0042] For a further optimized solution, a locking mechanism is installed in the insertion rod 16. The locking mechanism is drivingly connected to a connecting rod 10. The top of the connecting rod 10 extends out of the sleeve 7 and is fixedly connected to a handle 11. The connecting rod 10 is rotatably connected to the sleeve 7. The handle 11 controls the locking mechanism through the connecting rod 10, enhancing the stability of the insertion rod 16 after it is inserted into the soil.

[0043] For a further optimized solution, the locking mechanism includes a worm 18 fixedly connected to the connecting rod 10. The worm 18 meshes with a worm gear 19. A connecting shaft 20 is fixedly connected to the center of the worm gear 19. Second gears 21 are symmetrically fixedly connected to the connecting shaft 20. The second gears 21 mesh with a rack 23. A first wedge block 24 is fixedly connected to the top of the rack 23. The first wedge block 24 contacts a second wedge block 25. A limiting rod 27 is fixedly connected to the side wall of the second wedge block 25. When the first wedge block 24 moves upward, it squeezes the second wedge block 25, and the second wedge block 25 drives the limiting rod 27 to extend out of the insertion rod 16 and insert into the surrounding soil. The transmission ratio of the worm 18 and the worm gear 19 is large, and it is not easy to loosen after locking, enhancing the anti-pulling force. The gear-rack 23 mechanism converts the rotational motion into a linear motion, amplifying the locking force. When the first wedge block 24 rises, it squeezes the second wedge block 25, pushing the limiting rod 27 to horizontally extend and insert into the soil to form an anchoring point. After the insertion rod 16 is inserted into the loose soil, an effective anchor can still be provided through the limiting rod 27, which is suitable for various geological conditions. At the same time, the contact surface of the wedge block has a self-increasing resistance, improving the anti-pulling performance.

[0044] For a further optimized solution, a square tube 26 is sleeved outside the limiting rod 27, and an elastic member for resetting the limiting rod 27 is provided in the square tube 26. The square tube 26 restricts the moving direction of the limiting rod 27 to prevent skew damage. The elastic member can be arranged between the limiting rod 27 and the inner wall of the square tube 26, and one end of the elastic member is connected to the limiting rod 27 and the other end is connected to the inner wall of the square tube 26, facilitating the next use.

[0045] For a further optimized solution, the rack 23 is embedded in the track 22 and is slidably connected to the track 22. Both the outside of the track 22 and the square tube 26 are fixedly connected to the inner wall of the insertion rod 16 through fixing rods. The rack 23 is embedded in the track 22 and slides, and the track 22 and the square tube 26 are connected to the inner wall of the insertion rod 16 through fixing rods. The track 22 ensures that the rack 23 only moves along a fixed path, improving the transmission accuracy.

[0046] For a further optimized solution, an eccentric wheel 28 is fixedly connected to the connecting rod 10. The eccentric wheel 28 is located below the worm 18. An arc-shaped groove is formed in the eccentric wheel 28. A connecting column 29 is slidably connected in the arc-shaped groove. The bottom of the connecting column 29 is fixedly connected to a connecting plate 31. The connecting plate 31 is fixedly connected to the inner wall of the insertion rod 16. A limiting plate 30 is fixedly connected to the connecting plate 31. When the connecting rod 10 rotates, it drives the eccentric wheel 28 and the worm 18 to rotate, so that the limiting rod 27 and the limiting plate 30 extend into the insertion rod 16 or retract into the insertion rod 16. When the connecting rod 10 rotates, the arc-shaped groove of the eccentric wheel 28 drives the connecting plate 31 to move through the connecting column 29. At the same time, the worm 18 drives the limiting rod 27 to extend. A single action of the handle 11 simultaneously controls the extension of the limiting rod 27 and the limiting plate 30, simplifies the operation process, makes the insertion rod 16 more stable, enhances the protection effect, and the eccentric wheel 28 ensures the coordinated operation of multiple components, improving the reliability of the system.

[0047] For a further optimized solution, long rods 32 penetrate through the connecting plate 31 symmetrically. The two ends of the long rods 32 are respectively fixedly connected to the inner wall of the insertion rod 16. The long rods 32 are used to limit the moving direction of the connecting plate 31. The long rods 32 penetrate through the connecting plate 31 to limit its movement and prevent deviation. The arrangement of the double long rods 32 restricts the movement direction of the connecting plate 31, avoids jamming or skewing, reduces abnormal friction between components, improves durability, and extends the service life.

[0048] For a further optimized solution, a pair of vertical rods 12 are provided between the two sleeves 7. The top of the vertical rods 12 is fixedly connected to the bracket 6. The bottom of the vertical rods 12 has threads and is detachably connected to a counterweight 33. When the protective fence is set on a non-soil ground, the stability can be maintained by installing the counterweight 33 at the bottom of the vertical rods 12. The counterweight 33 is threadedly connected to the bottom of the vertical rods 12, and the anti-overturning ability of the fence is improved by increasing the weight. The counterweight 33 lowers the center of gravity and enhances the stability of the fence under strong wind or external force. The detachable design of the counterweight 33 adapts to different environmental requirements and improves versatility.

[0049] Embodiment 2

[0050] Refer to Figures 6-8As shown, different from Embodiment 1, the upper rotating plate 2 and the lower rotating plate 4 are replaced by an upper fixed plate 34 and a lower fixed plate 43. Both sides of the upper fixed plate 34 and the lower fixed plate 43 are provided with openings and are internally provided with telescopic components. The telescopic components include moving plates 36 symmetrically arranged inside the upper rotating plate 2 or the lower rotating plate 4. The transmission shaft is located between the two moving plates 36, and extrusion plates 38 are symmetrically and fixedly connected to the transmission shaft. A protective plate 35 is fixedly connected to the side wall of the moving plate 36. The protective plate 35 is adapted to the opening. A plurality of groups of springs 37 are arranged between the moving plate 36 and the inner wall of the upper rotating plate 2 or the lower rotating plate 4 to facilitate the reset of the moving plate 36. When the transmission shaft rotates, it drives the two extrusion plates 38 to rotate. The two extrusion plates 38 push the two moving plates 36 to move in opposite directions, thereby pushing out the protective plate 35. After the protective plate 35 extends out, the gap is eliminated, achieving a dust-proof effect. Compared with Embodiment 1, the structure of this embodiment is more stable, but it is not as flexible as Embodiment 1.

[0051] Embodiment 3

[0052] Referring to Figure 9 As shown, different from Embodiment 2, the original parts inside the upper fixed plate 34 and the lower fixed plate 43 are replaced by air bags 39, and the original parts inside the reinforcement plate 3 are replaced by a ventilation pipeline 40, an air extraction pump 41, and an air inflation pump 42. The air inflation pump 42 and the air extraction pump 41 are respectively connected to both ends of the ventilation pipeline 40. The ventilation pipeline 40 is connected to each air bag 39 through a connecting pipe. Valves are respectively arranged on the air inflation pump 42 and the air extraction pump 41.
