[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 This utility model provides a safety protection fence for power maintenance, including a fence panel 1. Fixing plates 3 are fixedly installed at both ends of the front and back bottom of the fence panel 1. A warning component is fixedly installed on the front of the fence panel 1. Posts 2 are fixedly installed on both sides of the fence panel 1. Moving components are slidably installed inside the posts 2. Locking components are fixedly installed on the outer sides of the two posts 2.

[0022] Furthermore, the warning components include a warning sign 5 and two warning strips 4. The two warning strips 4 are fixedly installed on the top and bottom of the front of the fence panel 1, respectively, and the warning sign 5 is fixedly installed in the middle of the front of the fence panel 1. After the protective fence is fixed, the warning strips 4 and the warning sign 5 are installed on the front of the protective fence to warn pedestrians passing by and prevent them from getting too close.

[0023] Furthermore, the movable component includes two sliding rods 6, which are slidably installed inside the two uprights 2. Each of the two ends of the bottom of the sliding rod 6 is rotatably mounted with a mounting base 7, and each of the four mounting bases 7 has a rotating wheel 8 rotatably installed inside. When moving the protective fence, the fence body can be pushed, and the rotating wheels 8 installed at the bottom of the two sliding rods 6 facilitate the movement of the protective fence to a designated location according to the location of power maintenance.

[0024] Furthermore, both sliding rods 6 are internally connected to lifting screws 9, which are rotatably installed inside the two columns 2. One end of each lifting screw 9 passes through the top of the two columns 2, and a first knob 10 is fixedly installed on the top of each lifting screw 9. After the protective fence is moved to the designated position, the two first knobs 10 are turned by hand to drive the two lifting screws 9 to rotate inside the two columns 2. When the lifting screws 9 rotate, the sliding rods 6 slide and rise inside the columns 2, driving the bottom rotating wheel 8 to rise and retract, so that the bottom of the fence panel 1 contacts the fixed plate 3 to the ground. The fixed plate 3 is fixed to the ground by screws or limiters, so that the protective fence is stable.

[0025] Furthermore, the locking assembly includes a locking housing 11 and a sliding base 12. The locking housing 11 and the sliding base 12 are respectively fixedly installed on the outside of the two columns 2. Two transmission blocks 15 are symmetrically slidably installed inside the sliding base 12. A locking block 16 is fixedly connected to one side of each of the two transmission blocks 15. The two locking blocks 16 are movably connected to the locking housing 11. When the two transmission blocks 15 move symmetrically inside the sliding base 12, they drive the two locking blocks 16 to move synchronously. The two locking blocks 16 move into the locking housing 11, so that the two locking blocks 16 complete the splicing of the two protective fences inside the locking housing 11. When the spliced ​​parts need to be disassembled after maintenance, the second knob 14 is rotated in the opposite direction to move the two locking blocks 16 out of the locking housing 11 to complete the unlocking.

[0026] Furthermore, a bidirectional lead screw 13 is rotatably installed inside the slide seat 12. The bidirectional lead screw 13 is connected between the middle of the two transmission blocks 15. One end of the bidirectional lead screw 13 passes through the top of the slide seat 12, and a second knob 14 is fixedly installed at one end of the bidirectional lead screw 13. Safety protection usually requires multiple guardrails 1. The two guardrails are brought close together so that the corresponding locking shells 11 on both sides are close to the slide seat 12. By turning the second knob 14, the bidirectional lead screw 13 is driven to rotate, so that it drives the two transmission blocks 15 to move symmetrically inside the slide seat 12.

[0027] In use, the protective fence in this embodiment can be moved by pushing the fence body. The rotating wheels 8 installed at the bottom of the two sliding rods 6 facilitate movement. The fence can be moved to a designated location based on the location of power maintenance. After the fence is moved to the designated location, the two first knobs 10 are turned by hand, causing the two lifting screws 9 to rotate inside the two columns 2 respectively. When the lifting screws 9 rotate, the sliding rods 6 slide upwards inside the columns 2, causing the rotating wheels 8 at the bottom to rise and retract, so that the bottom of the fence panel 1 contacts the fixed plate 3 on the ground. The fixed plate 3 is then fixed to the ground by screws or limiters, making the protective fence stable. For safety protection, multiple fence panels 1 are usually required. Two protective fences are placed close together, with their sides corresponding. The locking housing 11 approaches the slide seat 12. By turning the second knob 14, the double-acting screw 13 is rotated, causing the two transmission blocks 15 to move symmetrically inside the slide seat 12. When the two transmission blocks 15 move symmetrically inside the slide seat 12, they drive the two locking blocks 16 to move synchronously. The two locking blocks 16 move into the locking housing 11, so that the two locking blocks 16 are inside the locking housing 11 to complete the splicing of the two protective fences. When maintenance is required, the spliced ​​parts need to be disassembled. By turning the second knob 14 in the opposite direction, the two locking blocks 16 are moved out of the locking housing 11 to complete the unlocking. After the protective fence is fixed, the warning strip 4 and warning sign 5 are installed on the front of the protective fence to warn pedestrians and prevent them from getting too close.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
