[0036] Example

[0037] like Figure 1 , Figure 2 and Fig. 9 As shown, a fixing device for a substation safety fence includes a pole 10 and a fence mechanism 20 arranged between two of the poles 10, wherein the poles 10 are arranged on the ground through a fixing assembly 30;

[0038] The vertical pole 10 has a square cross-sectional area, and the bottom of the vertical pole 10 has a mounting portion 11. The fixing assembly 30 includes two mounting members 31 for being set on the ground, and the mounting member 31 includes an L-shaped bottom plate 311 and a vertical plate 312 set on one side of the L-shaped bottom plate 311. The vertical plates 312 of the two mounting members 31 form a closed cavity 313. The mounting portion 11 of the vertical pole 10 is used to be set in the closed cavity 313 by bolts, and the L-shaped bottom plate 311 is fixed to the ground by a fixing member.

[0039] In the present invention, the device includes a vertical pole 10 and a fence mechanism 20, and the vertical pole 10 is set on the ground through a fixing assembly 30. The vertical pole 10 has a square cross-sectional area and a mounting portion 11 at the bottom. The fixing assembly 30 includes two mounting members 31, each of which is composed of an L-shaped bottom plate 311 and a vertical plate 312, and the two vertical plates 312 surround a closed cavity 313. The mounting portion 11 of the vertical pole 10 is set in the closed cavity 313 by bolts, and the L-shaped bottom plate 311 is fixed to the ground by a fixing member. When in use, the mounting portion 11 of the vertical pole 10 is first inserted into the closed cavity 313 formed by the two mounting members 31 and fixed by bolts. Subsequently, the L-shaped bottom plate 311 is fixed to the ground using a fixing member to ensure that the vertical pole 10 is stable. The fixing member can be an expansion bolt, and the fence mechanism 20 is set between the two vertical poles 10 to form a complete safety fence. The larger area of ​​the L-shaped bottom plate 311 can increase the contact area between the pole 10 and the ground, and the L-shaped bottom plate 311 is fastened to the pole 10 and the ground respectively, which can increase the stability of the fence set on the ground. The design of this fixing device can ensure the stability of the substation safety fence under severe weather conditions such as strong winds, prevent the fence from being displaced or toppled, thereby protecting the on-site safety measures from being destroyed, reducing the difficulty of arranging safety measures for operation and maintenance personnel, and ensuring their safety.

[0040] like Figure 2 As shown, as a further technical solution, the vertical pole 10 is provided with a first connecting member 315 around it, and the first connecting member 315 has a first hook 3151, and both ends of the L-shaped bottom plate 311 have a mounting groove 316, and the mounting groove 316 has a first through hole 3111, and also includes a mounting block 317 for being arranged in the mounting groove 316 and ribs 318 arranged on both sides of the mounting block 317;

[0041] The rib plate 318 has a second hook 3181 on the side away from the mounting block 317, and the second hook 3181 is used to be hung on the first hook 3151. The mounting block 317 is located between the two rib plates 318 and has a second through hole 3182. The fixing piece passes through the first through hole 3111 and the second through hole 3182 to fix the second connecting piece and the L-shaped bottom plate 311 to the ground.

[0042] In this embodiment, the bottom mounting portion 11 of the vertical pole 10 is inserted into a closed cavity 313 surrounded by two L-shaped bottom plates 311 and a vertical plate 312. The mounting portion 11 of the vertical pole 10 is fixed in the closed cavity 313 by bolts to ensure that the vertical pole 10 is vertical and stable. First connecting members 315 are evenly arranged around the vertical pole 10, and each first connecting member 315 has a first hook 3151. Mounting grooves 316 are arranged at both ends of the L-shaped bottom plate 311, and first through holes 3111 are arranged in the mounting grooves 316. The mounting block 317 is placed in the mounting groove 316, and ribs 318 are arranged on both sides of the mounting block 317. The side of the rib 318 away from the mounting block 317 has a second hook 3181, and the second hook 3181 is hung on the first hook 3151 on the vertical pole 10 to achieve the connection between the vertical pole 10 and the L-shaped bottom plate 311. The fixing member passes through the first through hole 3111 and the second through hole 3182 on the mounting block 317, and fixes the second connecting member and the L-shaped bottom plate 311 on the ground to ensure the stability of the entire structure. The fixing member is an expansion bolt. By arranging the first connecting member 315 around the vertical pole 10 and arranging the mounting grooves 316 at both ends of the L-shaped bottom plate 311, the connection points between the vertical pole 10 and the ground are increased, thereby greatly improving the stability of the fence and reducing the displacement and tipping risks under severe weather conditions. The design of the first hook 3151 and the second hook 3181 makes the connection and disassembly between the vertical pole 10 and the L-shaped bottom plate 311 fast and easy, which is convenient for rapid deployment and maintenance on site. By increasing the connection points and using the fixing member to pass through the through hole for fixing, the overall wind resistance of the fence structure is enhanced, so that it can still remain stable in severe weather such as strong winds. The design of this fixing device allows for rapid adjustment and fixing under different terrain and ground conditions, improving the adaptability and flexibility of the fence.

[0043] like Figure 6 and Figure 7 As shown, as a further technical solution, the side wall of the upright pole 10 has symmetrically arranged mounting columns 12, the axis direction of the mounting columns 12 is perpendicular to the ground, the fence mechanism 20 includes a frame 21 and first mounting rods 22 arranged at both ends of the frame 21, and the first mounting rod 22 is slidably provided with mounting rings 23 at the upper and lower ends, and the mounting ring 23 is used to be sleeved on the mounting column 12;

[0044] It also includes an adjustment component 24 for adjusting the movement of the mounting ring 23 on the first mounting rod 22 . After the mounting ring 23 moves on the first mounting rod 22 , it is used to be sleeved or partially sleeved on the mounting column 12 .

[0045] As a specific implementation, in order to realize the movement of the mounting ring 23 on the first mounting rod 22, the present solution further includes an adjustment component 24. Through the operation of the adjustment component 24, the position of the mounting ring 23 on the first mounting rod 22 can be adjusted, so that the mounting ring 23 can be used as a further technical solution. The second piston rod 245 in the second piston chamber 244, after the second piston rod 245 moves in the second piston chamber 244, is used to push the first piston rod 242 to move in the first piston chamber 241, the first piston chamber 241 and the second piston chamber 244 are both used to store hydraulic oil, and the first piston rod 242 is sealed and slidably arranged in the first piston chamber 244, and the second piston rod 245 is sealed and slidably arranged in the second piston chamber 244.

[0046] As a specific implementation, a first piston cavity 241 is designed inside the first mounting rod 22, and first piston rods 242 are slidably arranged on both sides of the cavity, and the mounting ring 23 is fixed to the first mounting rod 22 through the first piston rod 242. A second mounting rod 243 is also provided on the frame 21, and a second piston cavity 244 is designed inside the second mounting rod 243, and the second piston cavity 244 is connected with the first piston cavity 241. A second piston rod 245 is arranged on the inner thread of the second piston cavity 244 of the second mounting rod 243, and the second piston rod 245 can move in the second piston cavity 244. When the second piston rod 245 moves in the second piston cavity 244, it will push the first piston rod 242 to move accordingly in the first piston cavity 241. This design allows the mounting ring 23 to be accurately adjusted on the first mounting rod 22 to meet different installation height and angle requirements. By rotating the second piston rod 245, the movement of the second piston rod 245 in the second piston chamber 244 can be controlled, thereby accurately controlling the movement of the first piston rod 242, and achieving fine adjustment of the mounting ring 23 on the first mounting rod 22. This adjustment mechanism not only improves the installation flexibility of the fence mechanism 20, but also enhances the stability and adaptability of the fence, so that it can better cope with different installation environments and conditions.

[0047] like Figure 7 As shown, as a further technical solution, it also includes a sliding sleeve 246, and the side wall of the sliding sleeve 246 has an opening 232. The sliding sleeve 246 is sleeved on both ends of the first piston rod 242. After the sliding sleeve 246 slides on the first piston rod 242, the mounting ring 23 slides in the opening 232. The sliding sleeve 246 is also provided with an elastic member 247 with one end arranged on the sliding sleeve 246 and the other end arranged on the first piston rod 242. The elastic member 247 is used to provide a force for the first piston rod 242 to move away from the first mounting rod 22.

[0048] As a specific embodiment, the side wall of the sliding sleeve 246 is designed with an opening 232, and the sliding sleeve 246 is sleeved on both ends of the first piston rod 242. When the sliding sleeve 246 slides on the first piston rod 242, the mounting ring 23 can slide accordingly in the opening 232 of the sliding sleeve 246, thereby realizing the precise adjustment of the position of the mounting ring 23. In order to ensure the stability of the first piston rod 242 and provide the necessary elastic force, an elastic member 247 is also provided inside the sliding sleeve 246. One end of the elastic member 247 is fixed on the sliding sleeve 246, and the other end is connected to the first piston rod 242. The main function of the elastic member 247 is to provide a force so that the first piston rod 242 can maintain a certain tension when not subjected to external force, and stay away from the first mounting rod 22, so that the mounting ring 23 can use the force of clamping the mounting column 12. This design not only helps to maintain the stable position of the mounting ring 23, but also can absorb the displacement caused by external impact or vibration to a certain extent, thereby enhancing the stability and durability of the entire fence mechanism 20. Through this design, the adjustment component 24 can ensure the precise adjustment of the position of the mounting ring 23 while also ensuring the stability and reliability of the fence mechanism 20 under various environmental conditions, further improving the overall performance of the substation safety fence.

[0049] like Figure 8 As shown, as a further technical solution, the mounting column 12 has a protrusion 121 , and the mounting ring 23 has a groove 231 , and the protrusion 121 is used to be slidably disposed in the groove 231 .

[0050] As a specific embodiment, in order to enhance the connection stability and sliding flexibility between the mounting ring 23 and the mounting post 12, the mounting post 12 is designed to have a protrusion 121, and the mounting ring 23 is provided with a groove 231. This design enables the protrusion 121 to be slidably set in the groove 231, providing a mechanical locking mechanism to ensure that the mounting ring 23 will not rotate and fall out during the sliding process on the first mounting rod 22. The protrusion 121 on the mounting post 12 is designed to match the size of the groove 231 of the mounting ring 23, and the protrusion 121 can slide freely in the groove 231 while maintaining the fixed position of the mounting ring 23. The coordinated use of the protrusion 121 and the groove 231 not only improves the positioning accuracy of the mounting ring 23 on the first mounting rod 22, but also enhances the vibration resistance and impact resistance of the entire fence mechanism 20, making it more stable when facing bad weather or external force impact.

[0051] like Figure 1 and Figure 3 As shown, as a further technical solution, an anti-climbing component 40 is provided on the top of the frame 21 .

[0052] As a further technical solution, the anti-climbing component 40 includes an elastic blade 41 in a spiral shape, one end of which is arranged on the frame 21, and the frame 21 has a sliding groove 42 arranged perpendicular to the direction of the vertical pole 10, and the frame 21 has a slider 43 slidably arranged in the sliding groove 42. The other end of the elastic blade 41 is arranged on the slider 43. After the slider 43 slides in the sliding groove 42, it is used to drive the elastic blade 41 to contract or extend. It also includes a threaded rod 44 that is rotatably arranged on the frame 21 and threadedly arranged on the slider 43. After the threaded rod 44 is rotated, it is used to drive the slider 43 to slide in the sliding groove 42.

[0053] As a specific implementation, a special anti-climbing component 40 is equipped at the top of the frame 21, the core of which is a spiral elastic blade 41 with one end fixed on the frame 21. Barbs can be provided on the spiral blade of the elastic blade 41 to prevent pedestrians from climbing over. The frame 21 is designed with a sliding groove 42 perpendicular to the direction of the vertical pole 10, which is used to guide and fix the movement of the slider 43. The slider 43 is slidably arranged in the sliding groove 42, and the other end of the elastic blade 41 is fixed on the slider 43. By moving the slider 43 in the sliding groove 42, the elastic blade 41 can be driven to contract or extend, thereby adjusting the extension degree of the blade to meet different protection requirements. In order to achieve precise control of the slider 43 in the sliding groove 42, a threaded rod 44 is also provided on the frame 21. The threaded rod 44 is rotatably arranged on the frame 21, and its threaded portion cooperates with the slider 43. When the threaded rod 44 rotates, its threaded portion can drive the slider 43 to slide along the direction of the sliding groove 42, thereby controlling the telescopic state of the elastic blade 41. When there is no need to prevent climbing, the elastic blade 41 can be adjusted to a retracted state to avoid accidental injury to the staff. During specific operation, by rotating the threaded rod 44, the position of the slider 43 can be accurately adjusted to control the extension degree of the elastic blade 41. This design not only enhances the flexibility and adaptability of the anti-climbing assembly 40, but also improves the safety and protection effect of the fence. Through this mechanical adjustment method, operation and maintenance personnel can easily adjust the state of the anti-climbing assembly 40 to meet different safety protection requirements and ensure the safe and stable operation of the substation.

[0054] like Figure 3 As shown, as a further technical solution, the anti-climbing assembly 40 further includes a knob 45 disposed at the end of the threaded rod 44 and a protective cover 46 for covering the knob 45 .

[0055] As a specific implementation, in order to protect the knob 45 from the influence of the external environment, such as rain, dust, etc., a protective cover 46 is specially designed outside the knob 45. The protective cover 46 can be covered on the knob 45 to provide additional protection, ensure that the operation of the knob 45 is not interfered by external factors, and also protect the operator from accidental injury. The design of the protective cover 46 not only improves the durability of the anti-climbing assembly 40, but also enhances its safety and practicality.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
