Description

Technical Field

[0001] This utility model relates to the field of power safety warning technology, and in particular to a power safety warning sign for pole-mounted operations. Background Technology

[0002] Pole work is a common form of high-altitude work in power system maintenance, repair, and emergency repair. Workers must perform live or de-energized operations at heights such as utility poles and towers, posing significant safety risks such as electric shock and falls. To ensure the safety of workers and those nearby, and to prevent accidental operation or unauthorized personnel from approaching, it is crucial to install prominent power safety warning signs. These signs, as key safety protection measures, directly impact the level of on-site safety management due to their visibility, stability, and installation efficiency.

[0003] Existing safety warning signs for high-altitude operations face significant challenges in practical application, including limited warning range and inconvenient expansion. Due to structural design limitations, most existing signs are fixed-size single structures, unable to be rapidly expanded laterally. This results in a limited warning area, making it difficult to effectively cover large work areas or multiple risk sources in complex terrain. This limitation necessitates the installation of multiple independent signs in scenarios requiring extensive isolation, such as large-scale maintenance or line renovations. This not only increases operational steps and time spent working at height, reducing installation efficiency, but also may create blind spots due to improper spacing or discontinuous layout of the signs, affecting the overall warning effect.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a new type of power safety warning sign for pole-mounted operations. This new sign should significantly improve the adjustability of the warning range and the ease of installation, while better meeting the needs of modern high-altitude power operations for efficient, reliable, and wide-range safety warnings, thus providing strong support for safe production in the power industry. Utility Model Content

[0005] The purpose of this utility model is to provide a power safety warning sign for pole-mounted operations, which solves the problem that existing signs are mostly fixed-size single structures due to structural design limitations, which cannot be quickly expanded in the horizontal direction, resulting in a limited warning area and difficulty in effectively covering a large area of ​​work or multiple risk sources in complex terrain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A power safety warning sign for pole-mounted operations includes several bases, which are arranged in a linear array along the horizontal direction of the bases. Each base is connected to a vertical plate on its top, a warning plate is connected to one side of the top of the vertical plate, and warning lights are fixedly connected to both sides of the top of the vertical plate.

[0008] One side of the upright plate is connected to a locking structure, and one side of the locking structure is provided with a connecting structure that is connected to the side wall of the upright plate and can be detachably connected to the locking structure.

[0009] Preferably, a connecting rope is provided between every two uprights, and the end of the connecting rope is fixedly connected to the side wall of the upright.

[0010] Preferably, the locking structure includes a locking screw, one end of which is connected to the side wall of the upright plate, and the other end of which is threaded with a locking nut.

[0011] Preferably, the connecting rope is made of nylon and has a reflective strip attached to its outer ring.

[0012] Preferably, the connecting structure includes a locking plate, one side of which is rotatably connected to the side wall of the upright plate via a pivot, and the other side is provided with a locking groove adapted to the locking screw.

[0013] Preferably, a fixing block is fixedly connected to the top of the base, the top of the fixing block is provided with an insertion groove adapted to the upright plate, a positioning screw with one end threaded through the fixing block is provided on one side of the fixing block, and a positioning hole adapted to the positioning screw is provided on the bottom side of the upright plate.

[0014] This utility model has the following beneficial effects:

[0015] By setting up several bases arranged in a linear array along the horizontal direction, with each base connected to a vertical plate on top, modular units that can be deployed independently or combined are formed, significantly improving the layout flexibility of the signage system. The warning plates on top of the vertical plates and the warning lights on both sides enhance the visual warning intensity of each unit, ensuring that the information is clearly identifiable. More importantly, by setting a locking structure on one side of the vertical plate, and in conjunction with a detachable connection structure connected to the side wall of the vertical plate, rapid lateral connection between adjacent signage units is achieved. Operators can freely increase or decrease the number of bases and vertical plates according to the actual work area, and by cooperating with the connection structure and the locking structure, multiple units can be spliced ​​into a continuous warning strip, effectively covering large work areas or multiple risk sources in complex terrain, avoiding the warning blind spots caused by improper spacing of multiple independent signs in traditional methods, and improving the continuity and integrity of the overall warning.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a pole-mounted power safety warning sign in this embodiment includes several bases 1, which are arranged in a linear array along the horizontal direction of the bases 1. Each base 1 is connected to a vertical plate 2 on its top, and a warning plate 5 is connected to the top of one side of the vertical plate 2. Warning lights 4 are fixedly connected to both sides of the top of the vertical plate 2.

[0026] A locking structure is connected to one side of the upright plate 2, and a connecting structure is provided on one side of the locking structure that is connected to the side wall of the upright plate 2 and is detachably connected to the locking structure.

[0027] When using the pole-mounted electrical safety warning sign, first determine the required number of bases 1 based on the scope of the work area and the number of risk points that need to be isolated. Arrange these bases in a horizontal linear array on the ground around the utility pole or work area, ensuring each base 1 is stably supported. Then, connect and fix the bottom of the upright plate 2 to the top of each base 1, ensuring the upright plate 2 is vertical and has sufficient structural stability to resist wind or accidental contact. Install a warning plate 5 on the top of one side of each upright plate 2 to display key safety information such as "Do Not Close the Switch," "Danger of Electricity," and "Work in Progress." Simultaneously, fix warning lights 4 to both sides of the top of the upright plate 2. The warning lights 4 can be flashing LEDs, emitting a conspicuous light signal both day and night, enhancing long-distance recognition and improving the overall warning effect. When multiple independent sign units need to be connected into a continuous warning strip, [further details are needed]. Rapid expansion is achieved through the combination of a connecting structure and a locking structure between adjacent upright plates 2. Specifically, one end of the connecting structure is connected to the side wall of an upright plate 2, while the other end is connected to the locking structure. The locking structure is located on one side of the adjacent upright plate 2, and the connecting structure is detachably connected through the locking structure, thereby firmly connecting the two upright plates 2 in the horizontal direction. Similarly, several bases 1 and their upper components can be connected in series through the connecting structure and the locking structure to form a continuous warning barrier extending in the horizontal direction, realizing flexible expansion of the warning area. When the work is completed or the warning range needs to be adjusted, it is only necessary to release the constraint of the locking structure on the connecting structure to remove the connecting structure from the upright plate 2, realizing rapid separation of each unit, which is convenient for storage, transportation and reuse. The entire installation and disassembly process does not require complicated tools, and the operation is simple and efficient, which meets the safety management needs of rapid response and flexible layout in high-altitude work sites.

[0028] Example 2

[0029] Please see Figure 1-5 As shown in this embodiment, a pole-mounted power safety warning sign is provided with a connecting rope 3 between every two upright plates 2. The end of the connecting rope 3 is fixedly connected to the side wall of the upright plate 2 with bolts. Specifically, by using the connection rope 3 between every two upright plates 2 and the bolts fixed to the side wall of the upright plate 2, after arranging multiple bases 1 and upright plates 2 as needed, the connecting rope 3 is used to connect adjacent upright plates 2 laterally. The end of the connecting rope 3 is firmly fixed to the side wall of the upright plate 2 with bolts, forming a continuous physical isolation zone. This can not only visually delineate the boundary of the work area, but also prevent personnel from unintentionally crossing it, thereby enhancing the continuity of the lateral connection and the physical barrier effect, and improving the on-site safety isolation strength.

[0030] The connecting rope 3 is made of nylon, and a reflective strip is attached to its outer ring. Specifically, by using nylon and attaching a reflective strip to its outer ring, the nylon material gives the connecting rope 3 high tensile strength and weather resistance, allowing it to withstand the tension and ultraviolet radiation in outdoor environments for a long time without easily breaking. The reflective strip on the outer ring can reflect external light sources at night or in low light conditions, significantly improving the visibility of the connecting rope 3. This ensures that the entire warning tape remains clearly visible at night, achieving the goal of enhancing structural durability while improving all-weather warning effectiveness.

[0031] Example 3

[0032] Please see Figure 1-5 As shown in this embodiment, a pole-mounted electrical safety warning sign includes a locking structure comprising a locking screw 13. One end of the locking screw 13 is connected to the side wall of the upright plate 2 via a mounting plate 14, and the other end of the locking screw 13 is threadedly connected to a locking nut 12. Specifically, by fitting the locking screw 13, with one end connected to the side wall of the upright plate 2 and the other end threadedly connected to the locking nut 12, when it is necessary to connect adjacent sign units, the locking groove 10 on the locking plate 6 of the connecting structure is aligned with the locking screw 13 and inserted, and then the locking nut 12 is tightened to press the locking plate 6, achieving quick locking. When disassembling, only the locking nut 12 needs to be unscrewed to remove the locking plate 6, thus providing a simple, convenient, and reliable detachable connection method that ensures a stable connection and facilitates quick assembly and disassembly.

[0033] The connecting structure includes a locking plate 6. One side of the locking plate 6 is rotatably connected to the side wall of the upright plate 2 via a pivot 11, and the other side has a locking groove 10 adapted to the locking screw 13. Specifically, the locking plate 6 is rotatably connected to the side wall of the upright plate 2 via a pivot 11 on one side, and has a locking groove 10 adapted to the locking screw 13 on the other side. When connecting adjacent units, the locking plate 6 can be rotated to a horizontal position around the pivot 11, so that the locking groove 10 is aligned with the locking screw 13 on the adjacent upright plate 2 and inserted, and then fixed with the locking nut 12. This structure allows the locking plate 6 to be rotated and folded away when not in use, avoiding space occupation or damage. When in use, it can be unfolded for quick connection, achieving the effect of improving the flexibility and convenience of connection operation, while optimizing the structural layout and storage performance.

[0034] A fixing block 7 is fixedly connected to the top of the base 1. The top of the fixing block 7 has an insertion groove 8 that matches the upright plate 2. A positioning screw 9 with one end threaded through the fixing block 7 is provided on one side of the fixing block 7. A positioning hole matching the positioning screw 9 is provided on the bottom side of the upright plate 2. Specifically, through the fixing block 7 fixedly connected to the top of the base 1, the insertion groove 8 that matches the upright plate 2 is provided on the top of the fixing block 7, the positioning screw 9 with one end threaded through the fixing block 7 is provided on one side of the fixing block 7, and the positioning hole matching the positioning screw 9 is provided on the bottom side of the upright plate 2, the bottom of the upright plate 2 is inserted into the insertion groove 8 of the fixing block 7 to achieve initial positioning. Then, the positioning screw 9 is tightened so that its end extends into the positioning hole of the upright plate 2, thereby firmly locking the upright plate 2 onto the base 1. This structure realizes quick disassembly and reliable fixation between the upright plate 2 and the base 1, achieving the effect of improving the installation stability of the upright plate and the efficiency of on-site assembly, and facilitating transportation and reuse.

[0035] When using the pole-mounted electrical safety warning sign, first determine the required number of bases 1 based on the size of the work area and the risk range. Arrange several bases 1 in a horizontal linear array around the utility pole or on the ground at the boundary of the work area, ensuring each base 1 is placed stably to provide basic support. Then, insert the bottom of the upright plate 2 into the insertion slot 8 on the fixing block 7 fixedly connected to the top of the base 1 for initial positioning. Next, tighten the positioning screw 9 on one side of the fixing block 7, allowing its threaded end to pass through the fixing block 7 and extend into the positioning hole on the bottom side of the upright plate 2, achieving a secure connection between the upright plate 2 and the base 1. This structure ensures the stability of the upright plate 2 and prevents it from tipping over. Install a warning plate 5 on the top of one side of each upright plate 2 to display safety information such as "Do Not Close the Switch" and "Danger of Electricity." Simultaneously, fix warning lights 4 to both sides of the top of the upright plate 2. The warning lights 4 use flashing LED light sources, which can continuously emit light signals during the day and night, enhancing long-distance visibility. When multiple independent units need to be connected into a continuous warning strip, use a connecting... The connection structure and locking structure work together to achieve lateral expansion. Specifically, the locking plate 6 in the connection structure is rotatably connected to the side wall of a vertical plate 2 via a pivot 11, allowing the locking plate 6 to rotate and unfold or retract around the pivot 11. During connection, the locking plate 6 is rotated to a horizontal position, aligning the locking groove 10 at its distal end with the locking screw 13 on the side wall of the adjacent vertical plate 2 and inserting it. Then, a locking nut 12 is screwed onto the outer end of the locking screw 13 and tightened, pressing and fixing the locking plate 6, thereby firmly connecting the two vertical plates 2 in the lateral direction. In addition, To further enhance the isolation effect, a connecting rope 3 is installed between every two adjacent uprights 2. The end of the connecting rope 3 is fixedly connected to the side wall of the upright 2 by bolts to form a physical barrier. The connecting rope 3 is made of nylon material, which has high strength and weather resistance. Its outer ring is connected with reflective strips, which can reflect light to improve visibility at night. The number of bases 1 and uprights 2 can be flexibly increased or decreased according to actual needs. The above structure can be quickly assembled into a continuous warning tape. After the operation is completed, it can be quickly disassembled by reversing the operation, which is convenient for storage and transportation.

[0036] This technical solution constructs an expandable modular warning system by arranging several bases 1 in a linear array along the horizontal direction, combined with the upright plate 2 connected to the top of each base 1. This effectively solves the problems of existing high-altitude work warning signs being unable to expand rapidly laterally and having limited warning area. The cooperation between the fixing block 7, the insertion slot 8, the positioning screw 9, and the positioning hole at the bottom of the upright plate 2 enables rapid installation and reliable fixation between the upright plate 2 and the base 1, improving on-site assembly efficiency and structural stability. The warning plate 5 on the top of the upright plate 2 and the warning lights 4 on both sides enhance the visual warning intensity of a single unit, ensuring that the information is clearly identifiable around the clock. The locking screw 13 and the locking nut 12 in the locking structure cooperate with the locking plate 6, the locking slot 10, and the rotating shaft 11 in the connection structure to achieve quick and detachable connection between adjacent sign units. The locking plate 6 can be rotated and retracted, making operation convenient and avoiding the need for additional tools. The connecting rope 3 is made of nylon and equipped with reflective strips, which enhances the nighttime reflective effect while providing physical isolation, improving the overall safety protection level.
