Description

Technical Field

[0001] This utility model relates to the field of warning fence technology, and in particular to a portable power safety warning fence device. Background Technology

[0002] Power safety warning fences are specialized safety protection facilities designed for power line operation and maintenance, equipment repair, or emergency repair. Through physical isolation structures and conspicuous warning signs, they delineate dangerous and safe work areas, preventing unauthorized personnel and vehicles from entering from both physical and early warning perspectives, thus avoiding power safety accidents such as electric shock, falls, and mechanical injuries.

[0003] When high-voltage lines are being maintained, the area around the work site is an open outdoor environment. Pedestrians and vehicles passing by may not be aware of the dangers of live wires and could accidentally enter and get electrocuted. Fences are needed to block these dangers. However, maintenance requires dynamic adjustments to the work area, and fixed barriers cannot be moved flexibly, which would hinder maintenance efficiency. Therefore, portable power safety warning fences are needed to quickly deploy and adapt to temporary maintenance scenarios.

[0004] Early power industry temporary isolation relied on fixed fences, consisting of welded metal supports and canvas warning tape. The welded metal supports established the physical isolation boundary, while the canvas warning tape, printed with high-voltage danger signs, was tied to the supports for visual warning. However, because the metal supports could not be folded, they were inconvenient to transport and could not meet the requirements for rapid deployment. To solve these problems, existing technology uses aluminum alloy folding support legs to replace the welded metal supports. Folding reduces the transport volume and allows for flexible arrangement. However, in actual use, due to the poor wind resistance of the device, additional counterweights are required to enhance stability and prevent tipping. However, the counterweights themselves are heavy and inconvenient to carry, increasing the handling burden and reducing deployment efficiency, thus failing to meet the needs of users. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a portable power safety warning fence device, including a support column 1, which is the load-bearing frame of the device. A support mechanism 2 is provided on the outer wall of the support column 1. A warning rod 4 is threadedly connected to the top inner side of the support column 1. A fixing mechanism 3 is provided on the right side of the outer wall of the warning rod 4. The support mechanism 2 includes a slip ring 201. The inner wall of the slip ring 201 is slidably connected to the middle of the outer wall of the support column 1. The slip ring 201 is sleeved on the middle of the outer wall of the support column 1 and can slide along the axial direction of the support column 1. Its function is to drive the support rod 202, which is hinged to the outer wall, to move synchronously by moving downward, thus providing power for the expansion of the support rod 202. The support rod 202 is rotatably connected to all four sides of the outer wall of the slip ring 201. The support rod 202 forms a quadrilateral support structure by unfolding, bearing the overall weight of the device and the counterweight pressure of the flexible bag 206. A fixing ring 203 is fixedly connected to the bottom of the support column 1. The fixing ring 203 provides a fixed hinge point for the connecting rod 204. The connecting rod 204 is rotatably connected to all four sides of the outer wall of the fixing ring 203. The other end of the multiple connecting rods 204 is rotatably connected to the middle of one side of the corresponding support rod 202. The function of the connecting rod 204 is to generate a lateral thrust on the support rod 202 when the slip ring 201 drives the support rod 202 to move downward, thereby rotating the axial movement of the slip ring 201. The radial expansion movement of the support rod 202 is transformed into that of the support rod 202. Hooks 205 are fixedly connected to the lower middle part of one side of the support rod 202. The function of the hooks 205 is to hang the connecting piece 207 of the flexible bag 206, providing a suspension support point for the flexible bag 206. The bottom of the support rod 1 is provided with a flexible bag 206. The flexible bag 206 serves as a counterweight container and can be folded and stored. By using materials sourced on site, dynamic counterweight is achieved by injecting them into the bag, adapting to the stability requirements of different wind speeds and terrains. Connecting pieces 207 are fixedly connected to the top and all four sides of the outer wall of the flexible bag 206. The outer walls of the multiple hooks 205 are slidably connected to the inner side of the corresponding connecting piece 207. A bag cover 208 is provided on the top of the flexible bag 206. The function of the bag cover 208 is to prevent the counterweight material inside the flexible bag 206 from leaking out during operation, ensuring the stability of the counterweight. Connecting components 209 are provided around the outer wall of the bag cover 208. Extension components 210 are provided at the bottom of the multiple support rods 202. The connecting component 209 includes multiple female stickers 2091. The tops of the multiple female stickers 2091 are fixedly connected to the outer walls of the bag cap 208. The upper and middle parts of the outer walls of the flexible bag 206 are fixedly connected to the female stickers 2092. The positions of the multiple female stickers 2092 correspond to the positions of the corresponding female stickers 2091. The female stickers 2091 and the female stickers 2092 are quickly attached by Velcro, so as to realize the quick sealing and opening of the bag cap 208 and the bag. The extension assembly 210 includes multiple threaded rods 2101, the tops of which are fixedly connected to the bottoms of corresponding support rods 202. Extension legs 2102 are threadedly connected to the bottoms of the outer walls of the multiple threaded rods 2101. The length of the extension legs 2101 can be adjusted by rotating the extension legs 2102 through threaded engagement. Specifically, when a fence needs to be installed at the construction site, by pushing the slip ring 201 downward along the support post 1, the downward movement of the slip ring 201 will cause the four support rods 202 hinged to its outer wall to move downward synchronously. Since the connecting rod 204 hinged to the middle of the support rod 202 and the fixed ring 203 forms a constraint, the connecting rod 204 will generate a lateral thrust on the support rod 202, causing the bottom of the four support rods 202 to expand synchronously in all directions until the slip ring 201 contacts the limiting ring 7 on the outer wall of the support post 1. Limited by the limiting ring 7, it cannot continue to slide downward, avoiding structural instability due to excessive unfolding angle. Then, the threaded sleeve 5 on the outer wall of the support post 1 is rotated. The threaded sleeve 5 moves downward with the thread engagement with the support post 1, pressing the top of the slip ring 201 to achieve the limit, thereby ensuring stable locking after the support structure is unfolded. After the support structure is unfolded, the flexible The bag 206 is attached to the hook 205 of the support rod 202 via connecting pieces 207 around its perimeter. The bag itself is lightweight and can be folded for storage during transportation. Sand, gravel, water, or other on-site materials can be directly injected into the bag as counterweight. After filling, the bag is quickly sealed by the female sticker 2091 of the bag cap 208 and the female sticker 2092 of the bag, completing the counterweight assembly. The counterweight weight can be flexibly adjusted according to the actual on-site conditions to adapt to different environmental needs. When the ground is uneven and the support is unstable, the extension leg 2102 at the bottom of the support rod 202 is rotated. The extension leg 2102 and the threaded rod 2101 at the bottom of the support rod 202 are connected by threads. During rotation, the extension leg 2102 moves axially along the threaded rod 2101, realizing fine adjustment of the length of a single support leg and improving adaptability in complex terrain.

[0020] Reference Figure 2 , Figure 3 and Figure 5The fixing mechanism 3 includes two limiting shells 301. The limiting shells 301 provide insertion space for the warning tape head, limit the fixed position of the warning tape, and prevent the warning tape from shifting or falling off. The left ends of the two limiting shells 301 are fixedly connected to the upper and lower sides of the right side of the outer wall of the warning rod 4. Each of the two limiting shells 301 has a sliding rod 302 on its right side. The left ends of the two sliding rods 302 pass through the right side of the corresponding limiting shell 301 and are fixedly connected to a pressure plate 303. Each of the two sliding rods 302 has a spring 304 sleeved on the left side of its outer wall. The right ends of the two springs 304 are fixedly connected to the right side of the inner wall of the corresponding limiting shell 301, and the left ends of the two springs 304 are fixedly connected to the right side of the corresponding pressure plate 303. The function of the pressure plate 303 is to press the warning tape head under the return force of the spring 304. The warning tape is fixed by the clamping force between the pressure plate 303 and the inner wall of the limiting shell 301. The spring 304 provides a continuous clamping force to the pressure plate 303. Pull rings 305 are fixedly connected to the right side of the outer wall of both sliding rods 302. The pull rings 305 provide a force application point, and the sliding rods 302 and pressure plates 303 can be moved by manually pulling them. A magnetic sheet 8 is fixedly connected to the top of the warning rod 4. A warning light 9 is set on the top of the warning rod 4. The warning light 9 provides a warning light source at night or in low visibility environments. It reminds non-working personnel to stay away from the isolation area by flashing or constant light signals, thereby enhancing the warning range and safety of the device. A magnetic sheet 10 is fixedly connected to the top of the warning light 9. The magnetic sheet 8 and the magnetic sheet 10 at the bottom of the warning light 9 form a magnetic attraction, which enables the quick fixing and disassembly of the warning light 9. A rotating ring 11 is rotatably connected to the top of the outer wall of the warning rod 4. The rotating ring 11 can drive the top shielding shell 12 to rotate synchronously. The shielding shell 12 is fixedly connected to the top of the rotating ring 11. The shielding shell 12 changes the blocking range of the light of the warning light 9 by adjusting the rotation angle. Specifically, after multiple support posts 1 are placed around the construction site, the warning pole 4 is first screwed into the top of the support post 1 to ensure a secure connection. Then, by pulling the pull ring 305, the sliding rod 302 is displaced. Simultaneously, the sliding rod 302 moves the pressure plate 303 along the inner side of the limiting shell 301. During this process, the spring 304 is compressed. Next, the warning tape end is inserted into the gap between the limiting shell 301 and the pressure plate 303. Afterward, the pull ring 305 is released, and the spring 304 returns to its original position, pushing the pressure plate 303 to move in the opposite direction. The pressure plate 303 and the inner wall of the limiting shell 301 clamp and secure the warning tape end. After completing the single-end fixing operation, the warning tape is then wrapped around the fixing mechanism 3 of the remaining support 1 in sequence to quickly form a closed fence, thereby improving the efficiency of fence construction. The warning light 9 is quickly fixed to the top of the warning pole 4 through the magnetic attraction between the magnetic plate 8 at the bottom and the magnetic plate 10 at the top of the warning pole 4, making it easy to install and remove. At the same time, rotating the rotating ring 11 on the outer wall of the warning pole 4 can drive the top shielding shell 12 to rotate synchronously. By adjusting the shielding angle of the shielding shell 12, the illumination range of the warning light 9 can be controlled to avoid glare from direct strong light hitting the workers and affecting operational safety. The light is concentrated and directed to non-working areas to enhance the pertinence of the warning.

[0021] Reference Figure 1 , Figure 2 and Figure 4 A threaded sleeve 5 is threadedly connected to the upper part of the outer wall of the support column 1. After the threaded sleeve 5 moves downward along the axial direction, it presses against the top of the slip ring 201, fixing the slip ring 201 between the limiting ring 2 7 and the threaded sleeve 5. This prevents the slip ring 201 from accidentally moving upward and causing the support rod 202 to retract when the support mechanism 2 is working. The outer wall of the threaded sleeve 5 is treated with anti-slip treatment. A limiting ring 1 6 is fixedly connected to the top of the outer wall of the support column 1. The limiting ring 1 6 prevents the threaded sleeve 5 from rotating upward and disengaging from the support column 1. A limiting ring 2 7 is fixedly connected to the lower part of the outer wall of the support column 1. The limiting ring 2 7 limits the downward movement limit position of the slip ring 201. Specifically, the threaded sleeve 5 is threadedly engaged with the outer wall of the support column 1. During rotation, it moves downward along the axis of the support column 1. The bottom of the threaded sleeve 5 presses against the top of the slip ring 201, fixing the slip ring 201 between the limiting ring 2 and the threaded sleeve 5. This prevents the slip ring 201 from accidentally moving upward during the operation of the support mechanism 2, causing the support rod 202 to retract, thus ensuring the stability of the support structure. The anti-slip treatment on the outer wall of the threaded sleeve 5 increases the friction between the hand and the threaded sleeve 5. The limiting ring 1 plays a limiting role on the threaded sleeve 5, preventing the threaded sleeve 5 from rotating and detaching from the support column 1.

[0022] Working principle: When setting up a fence at the construction site, the sliding ring 201 is pushed down along the support post 1. The downward movement of the sliding ring 201 causes the four support rods 202 hinged to the outer wall to move downwards simultaneously. The connecting rod 204, which is hinged to the fixed ring 203 in the middle of the support rod 202, forms a constraint. The connecting rod 204 generates a lateral thrust on the support rod 202, causing the bottom of the four support rods 202 to open outwards simultaneously until the sliding ring 201 contacts the limiting ring 7 on the outer wall of the support post 1. This prevents the structure from becoming unstable due to an excessively large opening angle. Then, the threaded sleeve 5 on the outer wall of the support post 1 is rotated. The threaded sleeve 5 moves downwards through the threaded engagement with the support post 1, pressing the top of the sliding ring 201 to achieve a limit, ensuring stable locking after the support structure is deployed. After the support structure is deployed, the flexible bag 206 is passed through the surrounding area. The connecting piece 207 is attached to the hook 205 on the support rod 202. The bag itself is lightweight and can be folded and stored during transportation. Sand, gravel, water, and other materials on site can be directly injected into the bag as counterweight. After filling, the bag is quickly sealed by the female sticker 2091 of the bag cover 208 and the female sticker 2092 of the bag, completing the counterweight assembly. The counterweight weight can be flexibly adjusted according to the site to adapt to different environmental needs. When the ground is uneven and the support is unstable, the extension leg 2102 at the bottom of the support rod 202 is rotated. The extension leg 2102 and the threaded rod 2101 at the bottom of the support rod 202 are connected by threads. During the rotation, the extension leg 2102 moves along the axial direction of the threaded rod 2101, realizing fine adjustment of the length of a single support leg and improving adaptability in complex terrain. After multiple support pillars 1 are placed in place, the warning rod 4 is first screwed into the top of the support pillar 1 to ensure a stable connection between the warning rod 4 and the support pillar 1. Then, by pulling the pull ring 305, the sliding rod 302 is moved. The sliding rod 302 simultaneously moves the pressure plate 303 along the inner side of the limiting shell 301. At the same time, the spring 304 is compressed. Then, the warning tape head is inserted into the gap between the limiting shell 301 and the pressure plate 303. The pull ring 305 is then released, and the spring 304 returns to its original position, pushing the pressure plate 303 to move in the opposite direction. The pressure plate 303 and the inner wall of the limiting shell 301 clamp and fix the warning tape head, completing the single-end fixation. Then, the warning tape is passed around the fixing mechanism 3 of the remaining support pillars 1 in sequence to quickly form a closed fence and improve the fence construction efficiency.
