A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and closing, carrying, and interrupting current under abnormal circuit conditions within a specified timeframe. Shockproof pole-mounted circuit breakers can be divided into various types, such as vacuum circuit breakers and sulfur hexafluoride circuit breakers, depending on their technical characteristics and application scenarios.

[0052] The following will provide a clear and complete description of the technology of a shock-resistant pole-mounted circuit breaker according to the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0053] Example
[0054] like Figure 1-Figure 4 As shown, a shockproof pole-mounted circuit breaker includes a circuit breaker body 10, a mounting frame 20, and a fixing bracket 40. The circuit breaker body 10 is conventional, and the fixing bracket 40 is mounted on a utility pole. A vertical buffer component 11 is fixed to one side of the circuit breaker body 10. The vertical buffer component 11 is used to adapt to the vertical vibration of the circuit breaker body 10 and absorb the vertical vibration force of the circuit breaker body 10.
[0055] A torsion buffer component 43 is fixed to one side of the mounting frame 20. The torsion buffer component 43 is used to adapt to the torsional vibration of the circuit breaker body 10 and absorb the torsional force on the circuit breaker body 10 to prevent the circuit breaker body 10 from twisting during vibration, thereby causing damage to the circuit breaker body 10.
[0056] Then, if Figure 3-Figure 6 As shown, a guide rail 23 is fixed to the inner cavity of the mounting frame 20, and a moving block 24 is slidably mounted on one side of the guide rail 23. The moving block 24 moves horizontally on the guide rail 23. A connecting frame 25 is fixed to the side of the moving block 24 away from the guide rail 23. A slide rail 26 is fixed to one side of the connecting frame 25. A slider 27 slides on the slide rail 26. The slider 27 moves horizontally on the slide rail 26. The installation positions of the moving block 24 and the slider 27 are perpendicular to each other, so that the directions of horizontal movement of the slider 27 and the moving block 24 are also perpendicular to each other. The slider 27 is fixedly connected to the vertical buffer component 11.
[0057] Two horizontal buffer assemblies 28 adapted to the slider 27 are fixed to the inner cavity of the mounting frame 20. The horizontal buffer assemblies 28 are located on both sides of the slider 27 in the horizontal movement direction and can provide a buffering force during the movement of the slider 27. Two horizontal buffer assemblies 29 adapted to the moving block 24 are fixed to the inner cavity of the mounting frame 20. The horizontal buffer assemblies 29 are located on both sides of the moving block 24 in the horizontal movement direction and can provide a buffering force during the movement of the moving block 24.
[0058] Then, if Figure 6As shown, a group of mutually perpendicular inverted T-plates 1 12 and a group of mutually perpendicular inverted T-plates 2 13 are fixed on the vertical buffer component 11, wherein the group of inverted T-plates 1 1 has two, and the two inverted T-plates 1 12 are symmetrical to each other, and the group of inverted T-plates 2 13 has two, and the two inverted T-plates 2 13 are symmetrical to each other. A group of mutually perpendicular winding components 2 22 and a group of winding components 1 21 are installed on the mounting frame 20, wherein the group of winding components 2 22 is located below the group of winding components 1 21, and the group of winding components 2 22 has two symmetrical winding components 2 22, and the group of winding components 1 21 has two symmetrical winding components 1 21. The outer surfaces of the winding components 2 22 and the winding components 1 21 are provided with a plurality of insulating ropes 30 that cooperate with the inverted T-plates 2 13 and the inverted T-plates 1 12;
[0059] The end of the insulating rope 30 away from the winding part 1 21 and the winding part 2 22 passes through the other winding part 1 21 and the winding part 2 22 and is fixedly connected between the inverted T-plate 12 and the inverted T-plate 2 13. The insulating rope 30 on one of the winding parts 1 21 in a group of winding parts 1 passes through the other winding part 1 21 and is connected to the inverted T-plate 12 on the different side of the winding part 1 21. The insulating rope 30 on one of the winding parts 2 22 in a group of winding parts 2 passes through the other winding part 2 22 and is connected to the inverted T-plate 2 13 on the different side of the winding part 2 22.
[0060] The two horizontal buffer assemblies 28 cooperate with a group of winding parts 21. The slider 27 moves and compresses the horizontal buffer assembly 28, causing the winding part 21 to rotate, thereby tightening the insulating rope 30 on the winding part 21, which can prevent the circuit breaker body 10 from moving too much in the moving direction. The two horizontal buffer assemblies 29 cooperate with a group of winding parts 22. The moving block 24 moves and compresses the horizontal buffer assembly 29, causing the winding part 22 to rotate, thereby tightening the insulating rope 30 on the winding part 22, which can prevent the circuit breaker body 10 from moving too much in the moving direction, thereby preventing the circuit breaker body 10 from colliding with other equipment.
[0061] Then, if Figure 7 As shown, the vertical buffer component 11 includes an installation box 111 fixedly connected to the slider 27. A plurality of support springs 112 are fixed to the inner cavity of the installation box 111. A buffer block 113 is fixed to one side of the plurality of support springs 112. The buffer block 113 slides in the inner cavity of the installation box 111. When the circuit breaker body 10 is subjected to vertical vibration, the buffer block 113 compresses the support spring 112. The support spring 112 provides a vertical buffering force, thereby alleviating the vertical vibration of the circuit breaker body 10. A placement plate 114 fixedly connected to the circuit breaker body 10 is fixed to one side of the buffer block 113. The placement plate 114 is used to install the circuit breaker body 10, so that the circuit breaker body 10 and the placement plate 114 are fixedly connected.
[0062] Among them, the inverted T-plate 1 12 and the inverted T-plate 2 13 are both fixed on the same side of the placement plate 114, and the horizontal portion of the inverted T-plate 1 12 is located above the horizontal portion of the inverted T-plate 2 13. The inverted T-plate 1 12 and the inverted T-plate 2 13 are both located on the side of the placement plate 114 away from the circuit breaker body 10, and the horizontal portion of the inverted T-plate 1 12 is located above the horizontal portion of the inverted T-plate 2 13, so that the inverted T-plate 1 12 and the inverted T-plate 2 13 will not affect each other.
[0063] Further, if Figure 6 As shown, the horizontal buffer assembly 1 28 and the horizontal buffer assembly 2 29 have the same structure. The horizontal buffer assembly 1 28 and the horizontal buffer assembly 29 are perpendicular to each other and cooperate with the slider 27 and the moving block 24 to prevent the circuit breaker body 10 from vibrating horizontally and being damaged due to the rigid connection during horizontal vibration.
[0064] Next, horizontal buffer assembly 29 includes two spring telescopic rods 291 fixedly connected to the inner cavity side wall of the mounting frame 20. A buffer plate 293 is fixed to the output end of the two spring telescopic rods 291. The buffer plate 293 corresponds to the movable block 24. The movable block 24 moves horizontally and contacts the buffer plate 293. The spring telescopic rods 291 provide a buffering force for the buffer plate 293, so that the movement of the movable block 24 is cushioned, thereby reducing damage caused by horizontal vibration of the circuit breaker body 10. Horizontal buffer assembly 1 28 corresponds to the slider 27. Similarly, when the slider 27 moves, the components of horizontal buffer assembly 1 28 also provide buffering, thereby reducing damage caused by horizontal vibration of the circuit breaker body 10.
[0065] Among them, two symmetrical racks 292 are fixed on one side of the buffer plate 293. The two racks 292 are adapted to the components in the winding component 22 to rotate the winding component 22, thereby winding the insulating rope 30, and then pulling the inverted T-plate 2 13, so that the circuit breaker body 10 is subjected to a force opposite to the moving direction. The length of the insulating rope 30 is constant, which can form a constraint to prevent the circuit breaker body 10 from being displaced too much during vibration, causing the circuit breaker body 10 to collide with other equipment and be damaged.
[0066] Further, if Figures 8-11 As shown, a set of winding components 22 and a set of guide rails 23 have the same structure. The winding components 22 and the guide rails 23 have the same structure and are installed perpendicular to each other and cooperate with the two horizontal buffer components 29 and the two horizontal buffer components 1 28.
[0067] Next, the second winding component 22 includes a rotating shaft 221 that is rotatably mounted on the mounting frame 20. The rotating shaft 221 penetrates the two side walls of the inner cavity of the mounting frame 20 and extends to the outside of the mounting frame 20. The rotating shaft 221 rotates at the penetration of the mounting frame 20. Two gears 222 that mesh with the rack 292 are fixed to the outer surface of the rotating shaft 221. The rack 292 moves, and the rotating shaft 221 rotates through the meshing gears 222. Two symmetrical pulleys 223 are mounted on the outer surface of the rotating shaft 221 through bearings. The pulleys 223 rotate on the outer surface of the rotating shaft 221. Two symmetrical winding drums 224 are fixed to the outer surface of the rotating shaft 221, and the winding drums 224 rotate with the rotating shaft 221.
[0068] The insulating rope 30 is fixed to the winding drum 224. As the winding drum 224 rotates, the insulating rope 30 is wound, so that the insulating rope 30 pulls the inverted T-plate 2 13 on the side not on the same side as the winding drum 224, so that the vertical buffer component 11 is subjected to a force opposite to the direction of movement, thereby slowing down or stopping the movement of the circuit breaker body 10.
[0069] Among them, such as Figure 8 As shown, the pulleys 223 and the winding drums 224 on the two winding components 22 of the same group are installed in different positions. The pulley 223 on one winding component 22 is in close contact with the mounting frame 20, and the winding drum 224 on the other winding component 22 is in close contact with the mounting frame 20. The winding drum 224 and the pulley 223 cooperate with each other. The winding drum 224 and the pulley 223 located on the same side and in the same straight line cooperate with each other, so that the insulating rope 30 on the winding drum 224 passes through the pulley 223 and is fixedly connected to the inverted T-plate 2 13;
[0070] The pulley 223 on the second winding component 22 is in close contact with the mounting frame 20, and the wire reel 224 on the second winding component 22 is away from the mounting frame 20, so that the wire reel 224 and the pulley 223 on the second winding component 22 cooperate with each other, with one wire reel 224 corresponding to one pulley 223;
[0071] like Figure 10 and Figure 11 As shown, by moving the slider 27 or the moving block 24, the horizontal buffer assembly 1 28 or the horizontal buffer assembly 29 is compressed, so that the winding component 1 21 or the winding component 2 22 rotates, so that the insulating rope 30 is wound and pulls the inverted T-plate 1 12 or the inverted T-plate 2 13, thereby limiting the displacement of the circuit breaker body 10.
[0072] Further, if Figure 12As shown, a worm gear set 41 is fixedly mounted on one side of the horizontal portion of the fixed bracket 40. The worm gear set 41 includes a worm mounted through a mounting bracket, and a worm wheel meshing with the worm. The rotation of the worm can rotate the worm wheel, while the worm wheel cannot rotate the worm, which can form a self-locking. A fixed circular plate 42 is fixed to the output end of the worm gear set 41. The output shaft of the worm wheel of the worm gear set 41 is fixedly connected to the center of one side of the fixed circular plate 42, so that the worm gear set 41 can rotate with the fixed circular plate 42. The worm gear set 41 is rotatably mounted on the horizontal portion of the fixed bracket 40, and the fixed circular plate 42 is fixedly connected to a torsion buffer component 43. The center of the torsion buffer component 43 is in the same straight line as the center of the mounting frame 20.
[0073] Further, if Figure 13 and Figure 14 As shown, the torsion buffer component 43 includes a circular groove block 431 fixedly connected to the fixed circular plate 42. Two symmetrical fixed blocks 432 are fixed in the inner cavity of the circular groove block 431. A set of buffer springs 433 are fixed on both sides of the two fixed blocks 432. The buffer springs 433 are curved.
[0074] Next, a rotating column 435 is rotatably installed at the center of the inner cavity of the circular groove block 431. There is no contact between the rotating column 435 and the fixed circular plate 42. The rotating column 435 only rotates in the inner cavity of the circular groove block 431. Two symmetrical rotating plates 434 are fixed on the outer surface of the rotating column 435. The rotating plates 434 are perpendicular to the fixed block 432. The rotating plates 434 are located between two groups of buffer springs 433 on the same side. The buffer springs 433 and the rotating plates 434 are tightly attached but not fixed, so that during the rotation of the rotating column 435, the rotating plates 434 can compress the buffer springs 433 on both sides, so that the rotating column 435 can rotate to both sides, thereby alleviating the torsional force on the rotating column 435 through the two groups of buffer springs 433. One side of the rotating column 435 is fixedly connected to a connecting circular plate 436 fixedly connected to the mounting frame 20. The connecting circular plate 436 is used to connect to the mounting frame 20.
[0075] The torsional vibration of the circuit breaker body 10 will cause the mounting frame 20 to rotate with the connecting circular plate 436, thereby causing the rotating column 435 to rotate with the two rotating plates 434. The elastic force provided by the two groups of buffer springs 433 can buffer the rotating plates 434 and absorb the torsional force.
[0076] It should be noted that the circuit breaker body 10, the cable reel 224, the spring telescopic rod 291 and the worm gear assembly 41 in the present invention are all prior art, and their installation and control methods are also conventional designs, which will not be elaborated in detail in the present invention.
[0077] Working Principle of the Present Invention: This device is a seismic-proof column-mounted circuit breaker. The vertical buffer component 11, the torsional buffer component 43, and the components within the inner cavity of the mounting frame 20 form a three-dimensional seismic isolation support, which simultaneously absorbs horizontal, vertical, and torsional vibration energy, thereby avoiding resonance or structural fatigue and improving the vibration adaptability of the device. Furthermore, the second and first winding components 22 and 21 can also reduce the horizontal displacement amplitude of the circuit breaker body 10, preventing the circuit breaker body 10 from colliding with other equipment.
[0078] like Figure 7 As shown, when the circuit breaker body 10 vibrates vertically, due to the fixed connection between the circuit breaker body 10 and the mounting plate 114, the force generated by the vertical vibration of the circuit breaker body 10 acts on the mounting plate 114 and the buffer block 113. The plurality of support springs 112 in the inner cavity of the mounting box 111 provide support for the buffer block 113, so that the support springs 112 can buffer the buffer block 113, thereby allowing the vertical buffer component 11 to absorb the rotational energy of the circuit breaker body 10 in the vertical direction;
[0079] like Figures 9-11 As shown, when the circuit breaker body 10 vibrates horizontally, the horizontal vibration occurs in two directions. Depending on the situation, the slider 27 or the movable block 24 will move. During the movement of the movable block 24, the movable block 24 pushes the buffer plate 293 in the moving direction, so that the spring telescopic rod 291 provides a buffering force for the buffer plate 293, alleviating the impact force of the moving block 24. The movable block 24 absorbs the vibration energy in the moving direction. Similarly, during the movement of the slider 27, the vibration energy in the moving direction of the slider 27 is absorbed by the component in the middle of the horizontal buffer assembly 1 28.
[0080] In addition, when the moving block 24 impacts the buffer plate 293, the buffer plate 293 will be displaced, thereby moving the two racks 292 on the buffer plate 293. The movement of the two racks 292 will cause the two gears 222 on the same side to rotate, causing the rotating shaft 221 to rotate. The rotation of the rotating shaft 221 causes the two winding drums 224 on the rotating shaft 221 to rotate, and the insulating rope 30 is wound. The two insulating ropes 30 on the winding drums 224 provide tension to the inverted T-plate 213 on the side different from the moving direction of the circuit breaker body 10, so that the vertical buffer component 11 is subjected to a tension different from the moving direction of the circuit breaker body 10, thereby reducing the horizontal moving force on the circuit breaker body 10, thereby reducing the vibration displacement amplitude of the circuit breaker body 10, preventing the circuit breaker body 10 from colliding with other equipment, and reducing the damage to the circuit breaker body 10 caused by excessive displacement amplitude.
[0081] The cooperation between the second and first winding components 22 and 21 and the second and first horizontal buffer components 29 and 28 can limit the displacement amplitude of the circuit breaker body 10 during horizontal vibration, thereby reducing the impact force of the circuit breaker body 10 while limiting the displacement of the circuit breaker body 10, preventing the circuit breaker body 10 from colliding with other equipment, and avoiding damage caused by excessive displacement amplitude of the circuit breaker body 10 during vibration.
[0082] Then, if Figure 13 As shown, the torsional vibrations applied to the circuit breaker body 10 act on the torsion buffer component 43 through the mounting frame 20. The torsion of the circuit breaker body 10 causes the mounting frame 20 to twist with the connecting circular plate 436. Two rotating plates 434 are fixed to the outer surface of a rotating column 435 fixed to the connecting circular plate 436. During rotation, the two rotating plates 434 are subjected to the elastic force of the buffer springs 433 in the inner cavity of the circular groove block 431, thereby limiting the torsion of the rotating plates 434. As a result, the torsional vibration energy of the circuit breaker body 10 is absorbed by the torsion buffer component 43, thereby preventing damage to the circuit breaker body 10 caused by the torsional vibrations.
[0083] In addition, the worm gear assembly 41 and the fixed circular plate 42 can rotate the angle of the circuit breaker body 10 when the circuit breaker body 10 is damaged, so that the circuit breaker body 10 installed in a complex environment can also be repaired by rotating the angle of the circuit breaker body 10 during maintenance, avoiding the problem of the circuit breaker body 10 needing to be disassembled as a whole when being repaired in a complex environment, thereby facilitating maintenance of the device.

Any equivalent replacement or modification of the shockproof pole-mounted circuit breaker and its inventive concept by any person skilled in the art within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention.
