DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Most of the electric safety fences in the prior art are fixed component structures, which cannot freely adjust the enclosure area according to construction needs during use. Moreover, when it is necessary to transfer back and forth between nearby maintenance points, workers need to carry and disassemble them manually, which has poor adaptability to working conditions and is inconvenient to use. In order to solve this technical defect in the prior art, Figure 1-Figure 4 As shown, this embodiment proposes an electric safety fence that is easy to retract, which can greatly improve the applicability of the fence, and reduce the floor space occupied by the fence when idle. It is easy to use. A telescopic fence mechanism 2 is detachably mounted on the fence mounting base 1, and a transfer auxiliary mechanism 3 is arranged at the lower end of the mounting base 1. After the telescopic fence mechanism 2 is installed, the mounting base 1 can be quickly moved under the action of the transfer auxiliary mechanism 3, and can be quickly fixed after reaching the designated location.

[0022] In order to flexibly adjust the enclosure area of ​​the fence, the present embodiment is provided with a telescopic fence mechanism 2. Specifically, the telescopic fence mechanism 2 includes a first enclosure plate 201 and a second enclosure plate 202. The first enclosure plate 201 and the second enclosure plate 202 are both provided with a reflective warning strip 203. A sliding link 204 is movably installed between the first enclosure plate 201 and the second enclosure plate 202. One end of the sliding link 204 is fixedly connected to the first enclosure plate 201, and the other end of the sliding link 204 is slidably connected to the second enclosure plate 202, so that the first enclosure plate 201 and the second enclosure plate 202 can be closer to or farther from each other, thereby changing the enclosure area of ​​the fence. A flexible rubber 205 is arranged between the two sliding links 204. When the first enclosure 201 and the second enclosure 202 move away from each other, the flexible rubber 205 will gradually unfold, thereby increasing the area of ​​the fence. A rectangular cavity for accommodating the flexible rubber 205 is opened inside the second enclosure 202. When the first enclosure 201 and the second enclosure 202 approach each other, the flexible rubber 205 will shrink into the inside of the rectangular cavity. Connecting hinges 206 are provided on the first enclosure 201 and the second enclosure 202. During power construction, the staff will use the connecting hinges 206 to connect multiple fences together in sequence to enclose the construction area.

[0023] In order to be able to quickly transfer and limit the fence, the present embodiment is provided with a transfer auxiliary mechanism 3. Specifically, the transfer auxiliary mechanism 3 includes a limiting slide groove 301 opened on the mounting base 1, a rotating base 302 is symmetrically arranged at the lower end of the mounting base 1, and a moving roller 303 is movably installed on the rotating base 302. A telescopic vertical rod 304 is arranged in the middle of the mounting base 1, and a limiting block 305 is detachably installed on the telescopic vertical rod 304. When installing the fence, the staff can use the moving roller 303 and the rotating base 302 to quickly transfer the fence, which is easy to use. The limiting block 305 is made of rubber. When the telescopic vertical rod 304 is extended downward, the limiting block 305 will contact the ground, thereby fixing the position of the mounting base 1.

[0024] Before overhauling the electric power equipment, the staff will first place the mounting base 1 in position, and then vertically insert the telescopic fence mechanism 2 into the interior of the limiting slide groove 301 .

[0025] Next, if Figure 3 As shown, the staff will pull the first enclosure 201 and the second enclosure 202 to both sides according to the construction needs. During the pulling process, the flexible rubber 205 will enclose the gap between the first enclosure 201 and the second enclosure 202, thereby increasing the enclosure area of ​​the telescopic fence mechanism 2.

[0026] Then, if Figure 1As shown, the staff will use the connecting hinge 206 to connect multiple telescopic fence mechanisms 2 in sequence, thereby completing the fencing operation of the construction area. Next, the staff will inspect and repair the power equipment in the fencing area.

[0027] When it is necessary to replace another nearby maintenance point, the staff can directly push the installation base 1 to move horizontally. When the installation base 1 moves, the first enclosure 201 and the second enclosure 202 will move synchronously, thereby achieving rapid transfer without manual handling and disassembly.

[0028] After reaching the designated location, the telescopic vertical rod 304 will automatically extend downward, and when the telescopic vertical rod 304 extends downward, the limiting block 305 will contact the ground, so that the position of the mounting base 1 is fixed to prevent the fence from moving during the power maintenance process.

[0029] This embodiment sets a telescopic fence mechanism 2, and utilizes the mutual cooperation between the sliding link 204 and the flexible rubber 205 to freely adjust the area of ​​the fence according to the construction needs on site, which can not only greatly improve the applicability of the fence, but also reduce the floor space occupied by the fence when idle, and is easy to use. Moreover, adjacent fences are rotatably connected by connecting hinges 206, which facilitates the adjustment of the shape of the enclosed area. In addition, this embodiment sets a transfer auxiliary mechanism 3, and utilizes the mutual cooperation between the moving roller 303 and the limiting block 305 to help the staff freely move the fence between nearby maintenance points without manual disassembly and transportation. Moreover, after the transfer is completed, the limiting block 305 will automatically limit the position of the mounting base 1 to prevent the mounting base 1 from moving during the power maintenance process.
