A circuit breaker is a switching device that can close, carry, and interrupt the current under normal circuit conditions, and can also close, carry, and interrupt the current under abnormal circuit conditions within a specified time. According to different technical characteristics and application scenarios, earthquake-proof pole-mounted circuit breakers can be divided into various types, such as vacuum circuit breakers, sulfur hexafluoride circuit breakers, etc.; in order to cope with the impact of natural disasters such as earthquakes on power equipment, earthquake-proof technologies have been introduced into the design of pole-mounted circuit breakers, and measures such as optimizing the structural design and using shock-absorbing materials are adopted to improve their seismic performance.

[0052] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solution of an earthquake-proof pole-mounted circuit breaker in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0053] Embodiment
[0054] As Figures 1-4 shown, an earthquake-proof 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 a prior art. The fixing bracket 40 is installed on a telegraph pole. A vertical buffer member 11 is fixed on one side of the circuit breaker body 10. The vertical buffer member 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] Among them, a torsional buffer member 43 is fixed on one side of the mounting frame 20. The torsional buffer member 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, preventing the circuit breaker body 10 from twisting during vibration, thereby causing damage to the circuit breaker body 10.
[0056] Next, as Figures 3-6 shown, a guide rail 23 is fixed in the inner cavity of the mounting frame 20. A moving block 24 is slidably installed 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 on the side of the moving block 24 away from the guide rail 23. A slide rail 26 is fixed on 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 moving directions of the slider 27 and the moving block 24 in the horizontal direction are also perpendicular to each other. The slider 27 is fixedly connected to the vertical buffer member 11.
[0057] Two first horizontal buffer components 28 adapted to the slider 27 are fixed in the inner cavity of the mounting frame 20. The first horizontal buffer components 28 are located on both sides of the horizontal moving direction of the slider 27 and can provide a buffer force during the movement of the slider 27. Two second horizontal buffer components 29 adapted to the moving block 24 are fixed in the inner cavity of the mounting frame 20. The second horizontal buffer components 29 are located on both sides of the horizontal moving direction of the moving block 24 and can provide a buffer force during the movement of the moving block 24.
[0058] Next, as Figure 6As shown in the figure, a set of inverted T-shaped plates one 12 and a set of inverted T-shaped plates two 13 that are perpendicular to each other are fixed on the vertical buffer member 11. There are two inverted T-shaped plates one 12 in a set, and the two inverted T-shaped plates one 12 are symmetric with each other. There are two inverted T-shaped plates two 13 in a set, and the two inverted T-shaped plates two 13 are symmetric with each other. A set of winding members two 22 and a set of winding members one 21 that are perpendicular to each other are installed on the installation frame 20. A set of winding members two 22 is located below a set of winding members one 21. There are two symmetric winding members two 22 in a set of winding members two 22, and there are two symmetric winding members one 21 in a set of winding members one 21. A number of insulating ropes 30 that cooperate with the inverted T-shaped plates two 13 and the inverted T-shaped plates one 12 are provided on the outer surfaces of the winding member two 22 and the winding member one 21;
[0059] Among them, one end of the insulating rope 30 far from the winding member one 21 and the winding member two 22 passes through the other winding member one 21 and the winding member two 22 and is fixedly connected between the inverted T-shaped plate one 12 and the inverted T-shaped plate two 13. The insulating rope 30 on one of the winding members one 21 in a set of winding members one 21 passes through the other winding member one 21 and is connected between the inverted T-shaped plate one 12 on the side different from this winding member one 21. The insulating rope 30 on one of the winding members two 22 in a set of winding members two 22 passes through the other winding member two 22 and is connected between the inverted T-shaped plate two 13 on the side different from this winding member two 22;
[0060] Two horizontal buffer components one 28 cooperate with a set of winding members one 21. The slider 27 moves to compress the horizontal buffer component one 28, so that the winding member one 21 rotates, so that the insulating rope 30 on the winding member one 21 is tightened, which can prevent the circuit breaker body 10 from displacing too much in the moving direction. Two horizontal buffer components two 29 cooperate with a set of winding members two 22. The moving block 24 moves to compress the horizontal buffer component two 29, so that the winding member two 22 rotates, so that the insulating rope 30 on the winding member two 22 is tightened, which can prevent the circuit breaker body 10 from displacing too much in the moving direction, thereby preventing the circuit breaker body 10 from colliding with other equipment.
[0061] Next, as Figure 7 shown, the vertical buffer member 11 includes an installation box 111 fixedly connected to the slider 27. A number of support springs 112 are fixed in the inner cavity of the installation box 111. A buffer block 113 is fixedly connected to one side of the number 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 vertically vibrated, the buffer block 113 will compress the support springs 112, and the support springs 112 provide a buffer force in the vertical direction, 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-shaped plate 12 and the inverted T-shaped plate 13 are both fixed on the same side of the placement plate 114, and the horizontal part of the inverted T-shaped plate 12 is located above the horizontal part of the inverted T-shaped plate 13. Both the inverted T-shaped plate 12 and the inverted T-shaped plate 13 are located on the side of the placement plate 114 away from the circuit breaker body 10. The horizontal part of the inverted T-shaped plate 12 is located above the horizontal part of the inverted T-shaped plate 13, so that the inverted T-shaped plate 12 and the inverted T-shaped plate 13 will not affect each other.
[0063] Furthermore, as Figure 6 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 2 29 are perpendicular to each other and cooperate with the slider 27 and the moving block 24, which can prevent the circuit breaker body 10 from being damaged due to rigid connection during horizontal vibration of the circuit breaker body 10.
[0064] Next, the horizontal buffer assembly 2 29 includes two spring telescopic rods 291 fixedly connected to the inner cavity side wall of the installation frame 20. The output ends of the two spring telescopic rods 291 are jointly fixed with a buffer plate 293. The buffer plate 293 corresponds to the moving block 24. When the moving block 24 moves horizontally and contacts the buffer plate 293, the spring telescopic rods 291 provide a buffer force for the buffer plate 293, so that the movement of the moving block 24 is buffered, reducing the damage caused by the horizontal vibration of the circuit breaker body 10. The horizontal buffer assembly 1 28 corresponds to the slider 27. Similarly, when the slider 27 moves, the components in the horizontal buffer assembly 1 28 can also provide buffering, thereby reducing the damage caused by the horizontal vibration of the circuit breaker body 10.
[0065] Among them, two symmetric 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 2 22, so as to make the winding component 2 22 rotate, thereby winding the insulating rope 30, and then pulling the inverted T-shaped plate 13, so that the circuit breaker body 10 is subjected to a force opposite to the moving direction. And the length of the insulating rope 30 is certain, which can form a constraint to prevent the displacement amplitude of the circuit breaker body 10 during vibration from being too large and causing the circuit breaker body 10 to collide with other equipment and be damaged.
[0066] Furthermore, as Figures 8-11 shown, a set of winding component 2 22 and a set of guide rails 23 have the same structure. The winding component 2 22 and the guide rails 23 have the same structure, are installed perpendicular to each other, and cooperate with the two horizontal buffer assemblies 2 29 and the two horizontal buffer assemblies 1 28.
[0067] Next, the second winding component 22 includes a rotating shaft 221 rotatably installed through the mounting frame 20. The rotating shaft 221 penetrates through 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 meshing with the rack 292 are fixed on the outer surface of the rotating shaft 221. When the rack 292 moves, the rotating shaft 221 rotates through the meshing gears 222. Two symmetric pulleys 223 are installed 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 symmetric winding discs 224 are fixedly installed on the outer surface of the rotating shaft 221. The winding discs 224 rotate with the rotating shaft 221;
[0068] Among them, the insulating rope 30 is fixed on the winding disc 224. As the winding disc 224 rotates, the insulating rope 30 can be wound up, so that the insulating rope 30 pulls the second inverted T-shaped plate 13 on the side different from the same side of the winding disc 224, so that the vertical buffer component 11 receives a force opposite to the moving direction, and the movement of the circuit breaker body 10 can be slowed down or stopped;
[0069] Among them, as Figure 8 shown, the installation positions of the pulleys 223 and the winding discs 224 on the two second winding components 22 in the same group are different. The pulley 223 on one second winding component 22 is in close contact with the mounting frame 20, and the winding disc 224 on the other second winding component 22 is in close contact with the mounting frame 20. The winding disc 224 and the pulley 223 cooperate with each other. The winding disc 224 and the pulley 223 on the same side and on the same straight line cooperate with each other, so that the insulating rope 30 on the winding disc 224 passes through the pulley 223 and is fixedly connected to the second inverted T-shaped plate 13;
[0070] When the pulley 223 on the second winding component 22 is in close contact with the mounting frame 20, the winding disc 224 on this second winding component 22 is far away from the mounting frame 20. When the winding disc 224 on the second winding component 22 is in close contact with the mounting frame 20, the pulley 223 on this second winding component 22 is far away from the mounting frame 20, so that the winding discs 224 and the pulleys 223 on the two second winding components 22 cooperate with each other, and one winding disc 224 corresponds to one pulley 223;
[0071] As Figure 10 and Figure 11 shown, by moving the slider 27 or the moving block 24, the first horizontal buffer component 28 or the second horizontal buffer component 29 is compressed, so that the first winding component 21 or the second winding component 22 rotates, and the insulating rope 30 is wound up to pull the first inverted T-shaped plate 12 or the second inverted T-shaped plate 13, thereby restricting the displacement of the circuit breaker body 10.
[0072] Furthermore, as Figure 12As shown, on one side of the horizontal part of the fixed bracket 40, a worm and worm gear set 41 is fixedly installed. The worm and worm gear set 41 includes a worm installed through a mounting frame, and a worm gear meshing with the worm. The rotation of the worm can cause the worm gear to rotate, while the worm gear cannot cause the worm to rotate, which can form a self-locking. A fixed circular plate 42 is fixed on the output end of the worm and worm gear set 41. The output shaft of the worm gear of the worm and worm gear set 41 is fixedly connected to the center of one side of the fixed circular plate 42, so that the worm and worm gear set 41 can drive the fixed circular plate 42 to rotate. The worm and worm gear set 41 is rotatably installed on the horizontal part of the fixed bracket 40. A fixed connection is provided between the fixed circular plate 42 and the torsion buffer member 43. The center of the torsion buffer member 43 is on the same straight line as the center of the mounting frame 20;
[0073] Further, as Figure 13 and Figure 14 shown, the torsion buffer member 43 includes a circular groove block 431 fixedly connected to the fixed circular plate 42. Two symmetric 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 bent;
[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 symmetric rotating plates 434 are fixed on the outer surface of the rotating column 435. The rotating plates 434 are perpendicular to the fixed blocks 432. The rotating plates 434 are located between the two sets of buffer springs 433 on the same side. The buffer springs 433 and the rotating plates 434 are in close contact 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 relieving the torsional force on the rotating column 435 through the two sets 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 the mounting frame 20;
[0075] The torsional vibration received by the circuit breaker body 10 will cause the mounting frame 20 to drive the connecting circular plate 436 to rotate, thereby causing the rotating column 435 to drive the two rotating plates 434 to rotate. The elastic force provided by the two sets 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 wire reel 224, the spring telescopic rod 291, and the worm and worm gear set 41 in the present invention are all prior arts, and their installation methods and control methods are also conventional designs. The present invention will not be elaborated in detail.
[0077] Working principle of the present invention: This device is a shock-proof pole-mounted circuit breaker. The vertical buffer component 11, the torsional buffer component 43, and the components in the inner cavity of the mounting frame 20 can form a three-dimensional vibration isolation support, which can absorb horizontal, vertical, and torsional vibration energy at the same time, thus avoiding resonance or structural fatigue, improving the vibration adaptability of the device. At the same time, the winding component two 22 and the winding component one 21 can also reduce the displacement amplitude of the circuit breaker body 10 in the horizontal direction, preventing the circuit breaker body 10 from colliding with other equipment;
[0078] As Figure 7 shown, when the circuit breaker body 10 vibrates vertically, since the circuit breaker body 10 is fixedly connected to the placement plate 114, the force generated by the vertical vibration of the circuit breaker body 10 acts on the placement plate 114 and the buffer block 113. A number of support springs 112 in the inner cavity of the installation box 111 provide support for the buffer block 113, so that the support springs 112 can buffer the buffer block 113, so that the vertical buffer component 11 can absorb the rotational energy of the circuit breaker body 10 in the vertical direction;
[0079] As Figures 9-11 shown, when the circuit breaker body 10 vibrates horizontally, there are two directions of horizontal vibration. Depending on the situation, the slider 27 or the moving block 24 will move. During the movement of the moving block 24, the moving block 24 will push the buffer plate 293 in the moving direction, so that the spring telescopic rod 291 provides a buffering force for the buffer plate 293, relieving the impact force of the moving block 24 during movement, so that the moving block 24 absorbs the vibration energy in the moving direction. Similarly, during the movement of the slider 27, the components in the middle of the horizontal buffer assembly one 28 absorb the vibration energy in the moving direction of the slider 27;
[0080] In addition, during the process of the moving block 24 impacting the buffer plate 293, the buffer plate 293 will be displaced, so that the two racks 292 on the buffer plate 293 move. The movement of the two racks 292 will drive the rotation of the two gears 222 on the same side, causing the rotation shaft 221 to rotate. The rotation of the rotation shaft 221 causes the two wire reels 224 on the rotation shaft 221 to rotate, winding the insulating ropes 30. The two insulating ropes 30 on the wire reels 224 provide a pulling force for the inverted T plate two 13 on the side different from the moving direction of the circuit breaker body 10, so that the vertical buffer component 11 receives a pulling force different from the moving direction of the circuit breaker body 10, thereby reducing the horizontal moving force on the circuit breaker body 10, 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 suffered by the circuit breaker body 10 due to excessive displacement amplitude
[0081] By the mutual cooperation among the set-up winding component two 22, winding component one 21, horizontal buffer component two 29 and horizontal buffer component one 28, the displacement amplitude of the circuit breaker body 10 during vibration can be restricted when the circuit breaker body 10 vibrates horizontally. Thus, while reducing the impact force of the circuit breaker body 10, the displacement of the circuit breaker body 10 is restricted, preventing the circuit breaker body 10 from colliding with other devices and avoiding the damage caused by excessive displacement amplitude of the circuit breaker body 10 during vibration.
[0082] Next, as Figure 13 shown, the torsional vibration received by the circuit breaker body 10 acts on the torsional buffer component 43 through the mounting frame 20. When the circuit breaker body 10 undergoes torsion, the mounting frame 20 will drive the connecting circular plate 436 to twist. Two rotating plates 434 are fixed on the outer surface of the rotating column 435 fixed on the connecting circular plate 436. When the two rotating plates 434 rotate, they will be subjected to the elastic force of the buffer spring 433 in the inner cavity of the circular groove block 431, so that the torsion of the rotating plates 434 is restricted, and thus the torsional vibration energy of the circuit breaker body 10 is absorbed by the torsional buffer component 43, avoiding the damage to the circuit breaker body 10 caused by torsional vibration.
[0083] In addition, by setting the worm and worm gear set 41 and the fixed circular plate 42, the angle of the circuit breaker body 10 can be rotated 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 that the whole needs to be disassembled during maintenance due to the circuit breaker body 10 being in a complex environment, and facilitating the maintenance of the device.
[0084] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered by the protection scope of the present invention.
