Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0019] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0020] In this embodiment: Reference Figure 1-2 As shown, a preferred embodiment of the present invention is provided.

[0021] The auxiliary device for the pole-mounted circuit breaker of this embodiment comprises two assembly brackets 1 and a pole-mounted circuit breaker 2 erected and installed by the assembly brackets 1. The assembly brackets 1 are also equipped with an auxiliary device 3 corresponding to the wiring part of the pole-mounted circuit breaker 2, and the auxiliary device 3 is used to provide support for the wiring cables of the wiring part of the pole-mounted circuit breaker 2; The auxiliary device 3 includes a mounting plate 31 fixed on the assembly bracket 1, and a rotating seat 32 and a stable swing seat 35 are respectively arranged on the mounting plate 31, and a connecting piece 351 is arranged between the rotating seat 32 and the stable swing seat 35. A telescopic sleeve 33 is connected to the rotating shaft on the rotating seat 32, and a clamping member 34 is telescopically arranged on the telescopic sleeve 33. The clamping member 34 is used to clamp the cable and adjust the cable support height through the telescopic sleeve 33. A tilting cylinder 36 is connected to the rotating shaft on the stable swing seat 35, and the tilting cylinder 36 is used to adjust the rotation angle of the telescopic sleeve 33 along the rotating seat 32. Furthermore, a limiting piece 322 is installed on the outer side of the bottom of the rotating seat 32 located at the mounting plate 31, and a limiting ring 323 is installed on the mounting plate 31 located on the outer side of the limiting piece 322. The limiting piece 322 rotates inside the limiting ring 323 and is used to limit the rotation angle of the rotating seat 32 and adjust the redundancy of the rotation of the rotating seat 32. Furthermore, a guide piece 311 is fixed to the mounting plate 31 by bolts. The guide piece 311 is arranged in an arc shape and has a guide groove. A slider 352 that slides in the guide groove is arranged at the bottom of the stable pendulum seat 35. When the cable swings due to wind factors, the rotating seat 32 will rotate. During this process, due to the presence of the connecting piece 351, the stable pendulum seat 35 will slide in the guide groove of the guide piece 311 through the slider 352. The sliding of the stable pendulum seat 35 can help share the force of the cable pushing the rotating seat 32 to rotate, and reduce the force on the cable at the wiring point. This can improve the stability of the cable, reduce stress concentration at the wiring point, and reduce the risk of damage.

[0022] See attached Figure 3 and attached Figure 5As shown, the bottom end of the telescopic sleeve 33 is provided with a rotating head 332 connected to the rotating shaft of the rotating seat 32, and the inner side of the end of the telescopic sleeve 33 is vertically connected with a lifting adjustment rod 333 and a second rotating rod 334 through a bearing, and the lifting adjustment rod 333 and the second rotating rod 334 are driven by helical gear meshing, and the second rotating rod 334 penetrates and extends to the outside of one side of the telescopic sleeve 33, and the outer thread of the second rotating rod 334 is connected to a telescopic rod 335 that penetrates and extends to the outside of the top of the telescopic sleeve 33, and the clamping member 34 includes a swing head 341, and the clamping member 34 is connected to the outer side of the telescopic sleeve 33 through the swing head The rotating shaft 341 is installed at the end of the telescopic rod 335. By rotating the lifting adjustment rod 333, the helical gear can be used to drive the second rotating rod 334 to rotate. The second rotating rod 334 pushes the telescopic rod 335 with its external thread connection to push the clamping member 34 to extend and retract, so that the position of the clamping member 34 can be adjusted according to the wiring height of the cable so as to clamp and fix it. The setting of the swing head 341 makes it more flexible to fix the cable, which can better adapt to the curvature of the cable bending, avoid the situation where the cable turning point is unevenly stressed, and prevent aggravated wear, thereby improving the stability of the cable. Furthermore, the internal thread of the tilting cylinder 36 is connected to a strut 361, the end of the strut 361 is connected to the top rotating shaft of the stable pendulum seat 35, the end bearing of the tilting cylinder 36 is connected to a connector 362, and a side ear 331 is provided on one side of the telescopic sleeve 33, and the side ear 331 is connected to the rotating shaft of the connector 362. The tilting cylinder 36 is rotated to make it telescope on the outside of the strut 361 through threads to adjust the distance between the stable pendulum seat 35 and the side ear 331, thereby adjusting the inclination angle of the telescopic sleeve 33. On the one hand, the tilting cylinder 36, the telescopic sleeve 33 and the connecting piece 351 form a stable triangle, which improves the stability of the auxiliary device 3, and at the same time can adapt to the adjustment of the support point position required by the cable, which is more flexible.

[0023] Refer to the attached Figure 4 As shown, the clamping member 34 also includes an upper clamping seat 343 and a lower clamping seat 342, and both sides of the upper clamping seat 343 and the lower clamping seat 342 are provided with a clamp-shaped protrusion 345, and a clamping rod 344 is clamped between the upper clamping seat 343 and the lower clamping seat 342 through the clamp-shaped protrusion 345, and the two ends of the clamping rod 344 are locked and fixed by locking bolts 3441. This method of fixing cables is convenient for loading and unloading, and when the wiring terminal of the pole-mounted circuit breaker 2 is fixed, a certain gap is created between the upper clamping seat 343 and the lower clamping seat 342 by loosening the locking bolts 3441, so that the cables can be simply supported without support, and the assembly process is not prone to twisting or tilting; at the same time, by adjusting the tightness of the locking bolts 3441, it can adapt to cables of different diameters, thereby improving versatility.

[0024] Refer to the attached Figure 6-7As shown, an extrusion sheet 321 is arranged on the outer side of one end of the rotating seat 32 located below the mounting plate 31, and the limiting sheet 322 is arranged in a V shape. Redundant springs 325 are installed between the inner walls of both sides of the extrusion sheet 321 and the limiting sheet 322. The redundant springs 325 act on both sides of the extrusion sheet 321 to limit the swing angle of the extrusion sheet 321 (that is, to limit the rotation angle of the rotating seat 32) and provide a certain buffer, so that when the cable is affected by wind and swings, it has a certain redundancy, reduces the impact of wind on the cable, and also avoids damage to other components caused by excessive swing of the cable; Among them, the inside of the two sides of the limit plate 322 is also connected with an adjusting rod 3222 through a thread, and the adjusting rod 3222 is located on the inner side of the limit plate 322 and is connected to a top plate 3223 through a bearing. One end of the redundant spring 325 is clamped and fixed to the surface of the top plate 3223. When the pole-mounted circuit breaker 2 cannot adjust its orientation according to the surrounding environment and the cable position, and is affected by a large unilateral wind force, the adjusting rod 3222 can be rotated to drive the top plate 3223 to compress or release the redundant spring 325, thereby increasing the force of the unilateral redundant spring 325, adapting to different environmental conditions, and improving the stability of the cable support.

[0025] Furthermore, a locking cylinder 324 is installed at the bottom of the mounting plate 31, and the end bearing of the locking cylinder 324 is connected to a first rotating rod 3241, and the external thread of the first rotating rod 3241 is connected to a locking rod 3242 that penetrates and extends to the outside of the other end of the locking cylinder 324, and a locking piece 3243 is arranged at the end of the locking rod 3242. The middle outer side of the limiting piece 322 is evenly distributed with locking grooves 3221 corresponding to the locking piece 3243. When the cable connected to the terminal block is in a non-linear state, it can be Rotating the first rotating rod 3241 drives the locking piece 3243 at the end of the threaded locking rod 3242 to push out the locking groove 3221 on the limiting piece 322. At this time, the deflection angle of the entire limiting piece 322 can be adjusted according to the tilt direction of the cable to better adapt to the tilt state of the cable, ensure good contact between the terminal block and the cable, and reduce the risk of poor contact and loose line. At the same time, this adjustable design increases the adaptability of the pole-mounted circuit breaker 2 to different installation environments and cable arrangements, so that it can better meet actual usage requirements.

[0026] Through the coordinated action of the mounting plate 31, the rotating seat 32, the stabilizing seat 35, the connecting piece 351, the telescopic sleeve 33, the clamping member 34, the tilting cylinder 36, the support rod 361, the side ear 331 and other components, the device can adapt to the height, angle and bending state of the cable under different working conditions. At the same time, in the clamping member 34, the upper clamping seat 343, the lower clamping seat 342 and the clamping rod 344 cooperate with each other, so that it can fix cables of different diameters, which is convenient for operation, maintenance and replacement; The stability of the cable is improved through the joint action of the guide piece 311, the stable swing seat 35, the slider 352, the connecting piece 351 and the telescopic sleeve 33. When the cable swings due to wind force, these components share the force of the cable pushing the rotating seat 32 to rotate, reducing the force on the cable at the connection point, reducing the stress at the connection point, and reducing the risk of damage; By utilizing the cooperation of components such as the rotating seat 32, the extrusion plate 321, the V-shaped limit plate 322, the redundant spring 325 and the adjusting rod 3222, the swing of the cable due to wind impact is reduced, and the stability of the cable in windy weather is improved. At the same time, the compression amount of the redundant spring 325 can be changed according to the actual unilateral wind force through the adjusting rod 3222, thereby further enhancing the windproof performance of the auxiliary device 3.
