Detailed Implementation

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-5As shown, the safety protection equipment for power equipment maintenance provided in this embodiment includes a mounting plate 1 and a folding arm assembly 2. The folding arm assembly 2 includes a first folding arm 201, a second folding arm 202, and a third folding arm 203. One end of the first folding arm 201 is connected to one end of the second folding arm 202, and the other end of the second folding arm 202 is connected to one end of the third folding arm 203. The other end of the third folding arm 203 is connected to a rotating shaft assembly 3. The first folding arm 201 is slidably mounted on the side of the mounting plate 1. A baffle 4 is fixedly mounted on the side of the mounting plate 1 near the first folding arm 201. The folding arm assembly 2 is folded between the mounting plate 1 and the baffle 4. A first sleeve 5 is fitted onto the end of the first folding arm 201 near the second folding arm 202, and a second sleeve 6 is fitted onto the end of the second folding arm 202 near the third folding arm 203. The second folding arm 202 and the third folding arm 203 are connected by a connecting piece 11. Both the second folding arm 202 and the third folding arm 203 are rotatably connected to the connecting piece 11. The outer side of the first folding arm 201 is provided with an external thread near the end of the second folding arm 202. The first sleeve 5 is provided with an internal thread near the end of the first folding arm 201. The end of the first sleeve 5 near the second folding arm 202 is slidably connected to the outside of the second folding arm 202. The mounting plate 1 is installed on both sides of the distribution box. The folding arm assembly 2 is folded between the mounting plate 1 and the baffle 4. When temporary maintenance of the distribution box is required, the folding arm assembly 2 is slid outward, and then the folding arm assembly 2 is unfolded. Then the first sleeve 5 is slid so that one end of the first sleeve 5 is fitted on the outside of the second folding arm 202. Then the first sleeve 5 is rotated to fix the first sleeve 5. At this time, the connection between the first folding arm 201 and the second folding arm 202 is fixed. Similarly, the second sleeve 6 is slid and rotated to fix the connection between the second folding arm 202 and the third folding arm 203.

[0024] The rotating shaft assembly 3 includes a turntable 301, a nylon belt 302, and a spring 303. The turntable 301 is rotatably connected to the third folding arm 203. A fixed shaft 7 is fixedly connected to the center of the turntable 301. A rotating sleeve 8 is sleeved on the outside of the fixed shaft 7. One end of the nylon belt 302 is fixedly connected to the rotating sleeve 8. One end of the spring 303 is fixedly connected to the turntable 301, and the other end of the spring 303 is fixedly connected to the turntable 301. A first limiting block 9 is provided at the end of the turntable 301 near the third folding arm 203, and a second limiting block 10 is provided at the end of the third folding arm 203 near the rotating shaft. The first limiting block 9 and the second limiting block 10 cooperate with each other. The second limiting blocks 10 are all 135-degree sector blocks. The first limiting block 9 and the second limiting block 10 cooperate with each other. When the turntable 301 rotates to a specific angle, the two limiting blocks contact each other, preventing the turntable 301 from continuing to rotate, thereby limiting the rotation range of the turntable 301 to the upward vertical and horizontal directions. After the folding arm assembly 2 is unfolded, one end of the nylon strap 302 is pulled out from the turntable 301 and then connected to the nylon strap 302 on the other side of the distribution box, thereby isolating the working area in front of the distribution box. In case of emergency temporary maintenance, there is no need to move the guardrail from the equipment room to the maintenance site for assembly and setting, thereby improving the efficiency of equipment maintenance.
