[0002] In order to improve the power supply reliability of the power grid, pole-mounted circuit breakers are often used on the connection, segmentation and branch lines in the power grid to improve the power supply reliability of the power grid; Since the pole-mounted circuit breaker is directly installed on the power pole, it is currently mostly fixed to the power pole using a triangular mounting bracket, and then the pole-mounted circuit breaker is moved to a high position by hoisting or a lifting mechanism. Finally, a worker climbs up to the high position of the power pole to align the mounting holes at the bottom of the circuit breaker with the mounting holes on the triangular mounting bracket and tighten them with bolts. Due to the large mass and long length of the circuit breaker, it is very difficult for the worker to align the mounting holes of the circuit breaker and tighten the bolts at the high position of the power pole, which poses a major safety hazard.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-11 , the present invention provides a technical solution: A pole mounted circuit breaker comprising: The installation unit 2 includes a support assembly 21 provided on the outside of the power pole 100 for supporting the circuit breaker body 101, and a lifting assembly 22 provided on one side of the support assembly 21 for lifting and removing the circuit breaker body 101 and the support assembly 21; The locking unit 1 is provided at the lower end of the lifting assembly 22 and is used to lock the circuit breaker body 101 and the lifting assembly 22 .

[0020] It should be noted that: in the process of installing the circuit breaker body 101 on the electric pole 100, the lifting assembly 22 is first fastened to the outside of the electric pole 100 through the support assembly 21, and then the circuit breaker body 101 is fastened to the lifting mechanism 225 from the bottom of the electric pole 100 and lifted to one side of the support assembly 21 through the lifting assembly 22. Finally, the circuit breaker body 101 is locked on the bearing plate 221 through the locking unit 1 to complete the installation of the circuit breaker body 101. The entire installation process does not require the removal of the fastening nuts between the circuit breaker body 101 and the tripod at a high place. The installation process is simple and reduces the hidden dangers of high-altitude operations.

[0021] As an improvement, Figure 2 , Figure 4-5 As shown, the support assembly 21 includes: A mounting panel 211 is provided on one side of the upper portion of the electric pole 100; There are at least two U-shaped frames 212, which are sleeved on the outside of the power pole 100, and one end of the U-shaped frame 212 passes through one end of the mounting panel 211 to the other end; The locking bolt 213 is threadedly connected to the outside of the U-shaped frame 212 and is used to tighten the mounting panel 211 to the outside of the power pole 100 .

[0022] Further, such as Figure 2-6 As shown, the lifting assembly 22 includes: The carrier plate 221 is fixedly connected to one side of the mounting panel 211. The lower end of the carrier plate 221 is fixedly connected to a support frame 2213. The other end of the support frame 2213 is fixedly connected to one side of the mounting panel 211, and is used to cooperate with the mounting panel 211 to support the carrier plate 221. A support rod 222 is fixedly connected to the upper end of the supporting plate 221 away from the mounting panel 211; A first rotating shaft 223, one end of which is rotatably connected to the interior of the mounting panel 211, and the other end of which is rotatably connected to the interior of the support rod 222. First guide wheels 2231 are fixedly mounted near both ends of the first rotating shaft 223. A second rotating shaft 224 is located on one side of the first rotating shaft 223. One end of the second rotating shaft 224 is rotatably connected to the interior of the mounting panel 211, and the other end is rotatably connected to the interior of the support rod 222. A winding wheel 2241 is fixedly mounted near each end of the second rotating shaft 224. A lifting mechanism 225 is provided on the upper end of the supporting plate 221 and is used to support the circuit breaker body 101; The adjustment mechanism 226 is provided at one end of the second rotating shaft 224 and is used to adjust the rotation of the second rotating shaft 224 .

[0023] Furthermore, Figure 3-4 As shown, the lifting mechanism 225 includes: A lifting plate 2251 is placed on the upper end of the supporting plate 221 , and the circuit breaker body 101 is fastened to the upper end of the lifting plate 2251 by bolts; There are two sets of limiting plates 2252, which are fixedly connected to the two ends of the lifting plate 2251 respectively; The lifting rope 2253 is fixedly connected to the middle of the upper end of the limiting plate 2252. The lifting rope 2253 passes through the first guide wheel 2231 and is wound around the outer side of the winding wheel 2241. The lifting rope 2253 is in a vertical state between the limiting plate 2252 and the first guide wheel 2231 .

[0024] The width of the limiting plate 2252 is greater than the width of the lifting plate 2251; The upper end of the supporting plate 221 and the two ends of the limiting plate 2252 are fixedly connected with guide rails 2211 for limiting the lifting plate 2251 and guiding the lifting and lowering of the lifting plate 2251 .

[0025] In addition, a guide opening 2212 is provided on the inner side of the upper end of the guide rail 2211 for guiding the limiting plate 2252 when it is placed into the guide rail 2211 .

[0026] As an improvement, the adjustment mechanism 226 includes: A first gear 2261 is fixedly connected to one end of the second rotating shaft 224; The second gear 2262 is meshed with one end of the first gear 2261. The second gear 2262 is located at one end of the mounting panel 211 and is fixedly connected to a limit block 22621. The limit block 22621 is cylindrical and rotatably connected to the inside of the mounting panel 211. The crank 2263 is fixedly connected to the center of one side of the second gear 2262 and is used to rotate and adjust the second gear 2262.

[0027] Furthermore, the outer diameter of the second gear 2262 is greater than the outer diameter of the first gear 2261 , so as to reduce the force of turning the crank 2263 .

[0028] Furthermore, if Figure 8-10 As shown, the locking unit 1 includes: The limiting posts 11 are provided in two groups and are fixedly connected to the lower end of the lifting plate 2251. The limiting posts 11 are slidably inserted into the interior of the supporting plate 221. The card slot 12 is provided on the side of the limiting column 11 and is located at the lower end of the supporting plate 221; The clamping mechanism 13 is mounted on the lower end of the supporting plate 221 and is used to extend into the clamping slot 12 to lock the limiting column 11 .

[0029] Wherein, the clamping mechanism 13 includes: A fixing plate 131 is fixedly connected to the lower end of the supporting plate 221 , and a guide groove 1311 is provided at the upper end of the fixing plate 131 ; The clamping plate 132 is slidably inserted into the guide slot 1311 and is used to be inserted into the clamping slot 12 to limit the position of the limiting column 11. A guide hole 2214 is provided inside the bearing plate 221 and outside the limiting column 11 to guide the movement of the limiting column 11; The pull rod 133 is fixedly connected to one end of the clamping plate 132 and is used to adjust the position of the clamping plate 132 .

[0030] It should be noted that: in the specific implementation process of the present invention, Figure 1-6 , Figure 11 As shown, when the circuit breaker body 101 needs to be installed on the upper part of the power pole 100, the U-shaped frame 212 cooperates with the locking bolt 213 to fasten the mounting panel 211 to the upper part of the power pole 100. Subsequently, the worker fastens the circuit breaker body 101 to the limiting column 11 on the ground with bolts in advance, then climbs to the top of the power pole 100 and turns the crank 2263. The crank 2263 drives the first gear 2261 to rotate through the second gear 2262, and the first gear 2261 drives the reel 2241 to rotate through the second shaft 224. The lifting rope 2253 is wound, so that the lifting rope 2253 drives the lifting plate 2251 to move upward through the limiting plate 2252. The lifting plate 2251 drives the circuit breaker body 101, which is previously fastened to it, to move from the upper end of the ground to just above the guide rail 2211. At this time, the worker inserts the lifting plate 2251 into the guide rail 2211 along the guide opening 2212, and the limiting column 11 is also simultaneously inserted into the guide hole 2214, completing the installation of the circuit breaker body 101 on the column. The worker does not need to align the mounting hole of the circuit breaker body 101 at a high altitude. like Figure 6 As shown, the present invention sets the outer diameter of the second gear 2262 to be smaller than the outer diameter of the first gear 2261, thereby ensuring that subsequent workers can save effort when turning the crank 2263 on the power pole 100, so that the heavy circuit breaker body 101 can be raised or lowered. like Figure 4-5 , Figure 7-10 As shown, the worker then pushes the pull rod 133, which drives the clamping plate 132 to move along the guide groove 1311, so that the two ends of the clamping plate 132 are respectively inserted into the clamping groove 12, completing the limiting work of the limiting column 11, so that the circuit breaker body 101 installed on the lifting plate 2251 is limited in the upper and lower positions. Under the limiting action of the guide rail 2211 on the front, back, left and right of the limiting plate 2252, the circuit breaker body 101 is fully positioned. During the entire installation process, there is no need to tighten the bolts of the circuit breaker body 101 on the power pole 100, which greatly reduces the safety hazards of high-altitude operations. like Figure 4-11As shown, in addition, when the circuit breaker body 101 on the power pole 100 needs to be disassembled and replaced, it is only necessary to pull the clamping plate 132 out of the clamping slot 12 through the pull rod 133, and then rotate the crank 2263. The crank 2263 drives the first gear 2261 to rotate through the second gear 2262, and the first gear 2261 drives the reel 2241 to reel the lifting rope 2253 through the second rotating shaft 224, so that the lifting rope 2253 drives the limit plate 2252 to move upward out of the guide rail 2211. The limit plate 2252 drives the circuit breaker body 101 to move upward through the lifting plate 2251. For the circuit breaker body 101 in a suspended state after being moved out, the worker pulls the circuit breaker body 101 from directly above the supporting plate 221 to one side of the supporting plate 221 on the power pole 100, and then releases the circuit breaker body 101 and slowly rotates the crank 2263 in the opposite direction, so that the circuit breaker body 101 slowly descends to the ground, completing the disassembly of the circuit breaker body 101. The disassembly process is simple and quick.
