Detailed Implementation
[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0019] Please see Figures 1-5This embodiment provides a pole-mounted circuit breaker installation structure, including a utility pole 1 and a front arc-shaped block 2. The front arc-shaped block 2 is installed on the outer wall of the utility pole 1 from top to bottom. A rear arc-shaped block 12 is screwed to the rear of the front arc-shaped block 2 by fixing bolts 11. The fixing bolts 11 are symmetrically arranged on the left and right sides. A connecting plate 13 is installed on the front end face of the front arc-shaped block 2. A front plate is installed on the front end face of the connecting plate 13. A pole-mounted circuit breaker 14 is installed on the upper end face of the front plate by welding. 1. An upper frame 16 is screwed to the upper end face by an upper bolt 15. A U-shaped frame 17 is installed at the bottom of the upper frame 16. A fixing bolt 11 is arranged on the inner end of the U-shaped frame 17. During operation, the utility pole 1 here is a partially enlarged structure. The fixing bolt 11 is limited and fixed by the U-shaped frame 17 to prevent the fixing bolt 11 from rotating and thus loosening and falling off. This improves the stability of the pole-mounted circuit breaker 14 installation and prevents falling parts from causing physical injury to pedestrians on the ground.
[0020] The pole-mounted circuit breaker 14 is symmetrically equipped with side frames on its left and right side walls. The side frames are screwed to the left and right side walls of the front plate by side bolts 18. During operation, the side bolts 18 improve the stability of the pole-mounted circuit breaker 14 and the front plate. The side frames limit the movement of the side bolts 18 to prevent them from loosening.
[0021] An outer clamping plate 19 is installed on the outer end of the side bolt 18, and a fixing plate is installed on the upper surface of the outer clamping plate 19. The upper surface of the fixing plate is connected to the front end of the upper frame 16 through an L-shaped frame 21.
[0022] The upper bolt 15 has a limiting pin 22 installed on its outer side wall by insertion. The limiting pin 22 passes through the L-shaped frame 21. The front end face of the L-shaped frame 21 has an annular groove. The inner side wall of the annular groove has symmetrical inner positioning grooves. An adjusting spring rod 23 is arranged in the inner positioning groove. An inner clamping plate 24 is installed on the inner end of the adjusting spring rod 23. The front end face of the limiting pin 22 has symmetrical slots. The inner clamping plate 24 is inserted into the slots. During operation, the limiting pin 22 is inserted and fixed to the upper bolt 15 to prevent it from rotating. The adjusting spring rod 23 drives the inner clamping plate 24 to move down. The inner clamping plate 24 limits the limiting pin 22, further improving the overall stability of the device.
[0023] Below the front arc-shaped block 2, an annular seat 25 is arranged. The annular seat 25 is welded to the outer wall of the utility pole 1. Multiple lower brackets 26 are installed at the bottom of the annular seat 25 along its circumferential direction. The other end of the lower bracket 26 is installed on the outer wall of the utility pole 1. During operation, the annular seat 25 supports the bottom of the connecting plate 13, thereby effectively preventing the connecting plate 13 from sliding down during long-term operation and ensuring the stability of the pole-mounted circuit breaker 14 during operation.
[0024] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
