Description

Technical Field

[0001] This utility model belongs to the field of power safety technology, and specifically relates to a power safety fence. Background Technology

[0002] Electrical safety fences are protective barriers designed for power plants, substations, and other electrical locations. They are primarily used to ensure the safety of personnel and pedestrians during electrical equipment maintenance, electrical experiments, and power distribution repairs. They are typically made of insulating materials such as plastic, rubber, or fiberglass to prevent current from being conducted through the fence to the surrounding environment, thus protecting personnel from the risk of electric shock. Electrical safety fences primarily separate electrical facilities from their surroundings through physical isolation. This not only prevents unauthorized personnel from approaching or touching live equipment, thus avoiding accidents such as electric shock, but also alerts people to the presence and potential dangers of electrical facilities, enhancing public safety awareness.

[0003] Chinese Patent Publication No. CN218176880U discloses a pre-embedded power safety fence, relating to the technical field of power safety fences. It includes a horizontal ground and connecting rods. Four sleeves are pre-embedded inside the horizontal ground, and conduits are fixedly connected to the bottom center of the inner cavity of each of the four sleeves. A sliding tube is movably connected to the outer wall of each conduit. The advantages of this invention are: by using pre-embedded sleeves and installing conduits inside the sleeves, combined with holes opened inside the sliding tubes, the sliding tubes can be raised and fixed using limiting pins. This allows for quick and easy placement of the fence, saving significant installation time, reducing the number of fences required, reducing the workload of workers, and improving maintenance efficiency. Furthermore, by using spring-connected telescopic rods with springs at both ends of the connecting rods, the fence can be quickly installed and dismantled at the desired location, improving applicability and practicality.

[0004] In practical use, this utility model is usually placed outside power facilities to provide necessary isolation and protection. However, the existing power safety fences are often fixed in structure, with their size and shape predetermined, making it difficult to adjust them flexibly according to actual needs. This fixedness limits the applicability of the fences in different application scenarios, because different power facilities and work areas may require enclosure structures of different sizes and shapes. Therefore, the existing power safety fences are not flexible and adaptable enough when dealing with diverse and frequently changing power operation environments, which to some extent affects their wide applicability and effectiveness. Utility Model Content

[0005] This utility model proposes an electrical safety fence to solve the problem that existing technologies are difficult to adapt to power facilities of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power safety fence, comprising:

[0007] Mounting columns and base plates;

[0008] A mounting slot is formed inside a mounting column, and a threaded rod is rotatably connected inside the mounting column. The external threads on both sides of the threaded rod are arranged in opposite directions.

[0009] Two limiting grooves are respectively opened on the upper and lower sides of the mounting column. Two matching limiting rings are provided in each of the two limiting grooves. A first crossbeam is provided on one side of the two limiting rings at the upper end, and a second crossbeam is provided on one side of the two limiting rings at the bottom end.

[0010] Two positioning rings are respectively fitted on both sides of the threaded rod, and the bottom end of the positioning ring located at the bottom end is provided with an installation sleeve.

[0011] In a preferred embodiment, both positioning rings are provided with threaded holes that are adapted to the threaded rod. The threaded rod passes through the two threaded holes and is threadedly connected to the side wall of the threaded hole. The upper end of the threaded rod passes through the mounting groove and extends to the outside.

[0012] In order to flexibly adjust the angle of the fence post, multiple abutment rods are provided on the opposite side of each of the two positioning rings. The multiple abutment rods pass through both sides of the mounting groove and abut against one side of the limiting ring in the two limiting grooves.

[0013] In a preferred embodiment, multiple railing bodies are provided between the two first crossbeams and the two second crossbeams on the same side, and the multiple railing bodies are respectively located on one side of the first crossbeam and the second crossbeam.

[0014] In a preferred embodiment, both the first and second crossbeams are provided with multiple fixing holes, and the same fixing bolt is provided between two fixing holes on the same side.

[0015] In a preferred embodiment, a support frame is rotatably connected to the bottom end of the first crossbeam, and the support frame is arranged in a "U" shape.

[0016] To ensure the stability of the fence during use, multiple support rods are rotatably connected to the bottom of the mounting post, and the bottom of each of the support rods is arranged in an "L" shape.

[0017] In a preferred embodiment, the bottom end of the mounting sleeve is provided with multiple mounting plates, each of which extends to the outside and is rotatably connected to a connecting rod. The multiple connecting rods are rotatably connected to the upper ends of multiple support rods respectively.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, through the limiting rings set at the ends of the first and second crossbeams, allows for flexible adjustment of the fence angle to adapt to various complex and changing scenario requirements. Combined with the positioning rings on both sides of the threaded rod and multiple abutment rods, it ensures that the multiple abutment rods accurately abut against the limiting rings on both sides when the threaded rod rotates, thereby achieving a stable angle lock. This not only enhances the structural stability of the power safety fence but also greatly improves its flexibility and adaptability during use, enabling the power safety fence to adapt to different specifications of power facilities and work area environments, demonstrating superior applicability and practicality.

[0020] 2. This utility model, through multiple support rods set at the bottom of the mounting column, and multiple mounting plates and connecting rods on the outside of the mounting sleeve, enables the power safety fence to be stably supported on the ground during use, effectively preventing the fence from tipping over or swaying. This not only significantly improves the stability of the power safety fence during use, but also ensures that it can maintain its optimal working condition in various complex environments, thus providing a more reliable and stable guarantee for the safety protection of power operation sites.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-4 This utility model provides a power safety fence, comprising:

[0029] Mounting column 1 and base plate 2;

[0030] An installation slot is provided inside the installation column 1. A threaded rod 3 is rotatably connected inside the installation column 1. The external threads on both sides of the threaded rod 3 are arranged in opposite directions.

[0031] Two limiting grooves are respectively opened on the upper and lower sides of the mounting column 1. Two matching limiting rings 4 are provided in each of the two limiting grooves. A first crossbeam rod 5 is provided on one side of the two limiting rings 4 at the upper end, and a second crossbeam rod 6 is provided on one side of the two limiting rings 4 at the bottom end.

[0032] Two positioning rings 7 are respectively fitted on both sides of the threaded rod 3, and the bottom end of the positioning ring 7 is provided with an installation sleeve 8.

[0033] Specifically, such as Figure 3 As shown, both positioning rings 7 are provided with threaded holes that are compatible with the threaded rod 3. The threaded rod 3 passes through the two threaded holes and is threadedly connected to the side wall of the threaded hole. When the threaded rod 3 rotates, it will drive the two positioning rings 7 to move in opposite directions. When it stops rotating, it can lock its position. The upper end of the threaded rod 3 passes through the mounting groove and extends to the outside.

[0034] Specifically, such as Figure 3 As shown, each of the two positioning rings 7 has multiple abutting rods 9 on its opposite side. The multiple abutting rods 9 pass through both sides of the mounting groove and abut against one side of the limiting ring 4 in the two limiting grooves.

[0035] By design, the first crossbeam 5 and the second crossbeam 6 are each equipped with a limiting ring 4 at one end, which allows the angle of the power safety fence to be flexibly adjusted. By pressing multiple abutting rods 9 against the limiting rings 4 on both sides, the positions of the first crossbeam 5 and the second crossbeam 6 can be locked, thereby fixing the angle of the power safety fence.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, multiple railing bodies 10 are provided between the two first crossbeams 5 and the two second crossbeams 6 on the same side. The multiple railing bodies 10 are located on one side of the first crossbeams 5 and the second crossbeams 6, and the multiple railing bodies 10 on one side of the first crossbeams 5 and the second crossbeams 6 can effectively play a protective role.

[0037] Specifically, such as Figure 1 and Figure 2As shown, both the first crossbeam 5 and the second crossbeam 6 are provided with multiple fixing holes, and the same fixing bolt 11 is provided between two fixing holes on the same side. The multiple fixing holes and multiple fixing bolts 11 on the first crossbeam 5 and the second crossbeam 6 can flexibly adjust the length of the power safety fence, so that it can be further adapted to different power facilities and work areas.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, a support frame 12 is rotatably connected to the bottom end of the first crossbeam 5. The support frame 12 is arranged in a "U" shape. The "U"-shaped support frame 12 can increase the floor area of ​​the power safety fence, thereby ensuring its stability in use.

[0039] See Figure 1-4 When using a power safety fence, the positions of multiple first crossbeams 5 and multiple second crossbeams 6 need to be adjusted according to the power facilities and work areas to be protected, and then fixed with multiple fixing bolts 11. This allows for adjustment of the length of the power safety fence. Next, rotating multiple limiting rings 4 adjusts the angle of the power safety fence. Then, rotating the threaded rod 3 causes the positioning rings 7 on both sides to move in opposite directions. The two positioning rings 7 then move multiple abutment rods 9, causing them to abut against one side of the limiting rings 4 on both sides. This fixes the angle of the power safety fence, allowing it to adapt to different specifications of power facilities and work areas.

[0040] Example 2:

[0041] Please see Figure 1-4 This utility model provides a power safety fence, comprising:

[0042] Mounting column 1 and base plate 2;

[0043] An installation slot is provided inside the installation column 1. A threaded rod 3 is rotatably connected inside the installation column 1. The external threads on both sides of the threaded rod 3 are arranged in opposite directions.

[0044] Two limiting grooves are respectively opened on the upper and lower sides of the mounting column 1. Two matching limiting rings 4 are provided in each of the two limiting grooves. A first crossbeam rod 5 is provided on one side of the two limiting rings 4 at the upper end, and a second crossbeam rod 6 is provided on one side of the two limiting rings 4 at the bottom end.

[0045] Two positioning rings 7 are respectively fitted on both sides of the threaded rod 3, and the bottom end of the positioning ring 7 is provided with an installation sleeve 8.

[0046] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, multiple support rods 13 are rotatably connected to the bottom of the mounting column 1, and the bottom of each support rod 13 is set in an "L" shape.

[0047] Its design incorporates multiple rotatable support rods 13, enabling the power safety fence to be supported on the ground during use, increasing its floor space and effectively ensuring its stability and sturdiness during use.

[0048] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the mounting sleeve 8 is provided with multiple mounting plates 14, all of which extend to the outside and are rotatably connected to connecting rods 15. The multiple connecting rods 15 are rotatably connected to the upper ends of multiple support rods 13. When the mounting sleeve 8 moves up and down, it can drive the multiple support rods 13 to rotate through the multiple mounting plates 14 and multiple connecting rods 15, so that it can be stored outside the mounting column 1 when not in use, which is convenient for storing or transporting the power safety fence.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
