[0002] As an electrical device, the main function of the circuit breaker is to protect the circuit from overload, short circuit and other faults. In order to ensure the safe operation and extend the service life of the circuit breaker, the installation environment and installation method of the circuit breaker are very critical. As a device used to fix and support the circuit breaker, the insulating mounting frame not only needs to provide sufficient mechanical support, but also needs to ensure electrical safety and stability.

[0003] In the process of clamping and fixing the circuit breaker, the existing circuit breaker mounting frame may not evenly distribute the fixing force, resulting in the circuit breaker being not accurately positioned on the mounting frame or being loose, which in turn affects the normal working state of the circuit breaker. Therefore, a circuit breaker insulation mounting frame is proposed. Summary of the invention

[0004] The present invention aims to solve the technical problem of how to prevent the circuit breaker from loosening due to uneven fixing force by making the circuit breaker receive uniform fixing force from a fixing device, and provides a circuit breaker insulating mounting frame.

[0005] The technical solution adopted by the present invention to solve the technical problem is: A circuit breaker insulation mounting frame comprises a mounting frame shell, a clamping and fixing device, an ejection device, a heat dissipation device and a controller.

[0006] The outer shell of the mounting frame is arranged horizontally and fixedly connected to the wall.

[0007] The clamping and fixing device is arranged on the housing of the mounting frame and is used for clamping and fixing the circuit breaker.

[0008] The ejection device is arranged on the housing of the mounting frame and is used for ejecting the housing of the circuit breaker.

[0009] The heat dissipation device is arranged on the housing of the mounting frame and is used for dissipating heat from the circuit breaker.

[0010] The controller is fixedly connected to the side of the mounting frame shell, and the controller is electrically connected to the clamping and fixing device and the heat dissipation device respectively.

[0011] When using this equipment, the staff places the circuit breaker in the housing of the mounting frame, fixes the circuit breaker through the clamping device, and dissipates heat from the circuit breaker through the heat dissipation device. When the circuit breaker needs to be taken out for maintenance, the ejection device ejects the circuit breaker, making it convenient for the staff to take out the circuit breaker.

[0012] Furthermore, the clamping and fixing device includes a mounting box, a cylinder, a mounting plate, a plurality of first springs, and a fixing plate.

[0013] The installation box is arranged inside the installation frame shell, close to the inner top surface of the installation frame shell, and the upper part of the installation box is fixedly connected to the inner top surface of the installation frame shell.

After the fixing plate contacts the top of the circuit breaker, the mounting plate continues to move downward relative to the fixing plate, and then the first springs contract, so that the fixing plate fixes the top of the circuit breaker.

[0019] When it is necessary to release the top of the circuit breaker, the staff controls the telescopic rod of the cylinder to move upward through the controller, and the telescopic rod of the cylinder drives the two movable rods to open, and drives the mounting plate to move upward. The mounting plate first moves up relative to the fixed plate. After the first springs are reset, the mounting plate drives the first springs to move upward, and the first springs drive the fixed plate to move upward, thereby releasing the fixation of the top of the circuit breaker.

[0020] Furthermore, the clamping and fixing device includes two sliding grooves, two round rods, two sliding blocks, two sliding plates, two movable rods, a plurality of second springs, and two clamping plates.

[0027] The two clamping plates are respectively parallel to the two sliding plates, and are arranged inside the mounting frame housing, below the fixed plate, and between the two sliding plates. The two clamping plates are respectively fixedly connected to opposite ends of a plurality of second springs.

[0028] When it is necessary to clamp and fix the two sides of the circuit breaker, the telescopic rod of the cylinder drives the two movable rods to contract, the two movable rods drive the two sliding plates to move toward each other, the two sliding plates drive the plurality of second springs to move toward each other, the plurality of second springs drive the two clamping plates to move toward each other, after the two clamping plates contact the two sides of the circuit breaker, the two sliding plates continue to move toward each other relative to the two clamping plates, and then the plurality of second springs contract, so that the two clamping plates clamp and fix the circuit breaker.

After the second springs are reset, the two sliding plates drive the second springs to move in the opposite direction, and the second springs drive the two clamping plates to move in the opposite direction, thereby releasing the clamping of the circuit breaker.

[0038] The axis of the second cylinder body is parallel to the axis of the round rod, and is arranged inside the mounting frame shell, on the side of the slide groove away from the cylinder. The second cylinder body is fixedly connected to the inner bottom surface of the mounting frame shell, and a vent hole is arranged on the side of the second cylinder body close to the placement box.

[0039] The axis of the second piston coincides with the axis of the second cylinder body, and the second piston is arranged inside the second cylinder body. The second piston is slidably connected to the inner wall of the second cylinder body, and the sliding direction is parallel to the axis of the second cylinder body.

[0040] The telescopic direction of the two first telescopic rods is parallel to the axis of the second cylinder body, and they are symmetrically arranged inside the second cylinder body, on the side of the second piston away from the placement box.

[0043] The connecting pipe is arranged inside the mounting frame shell, one end of the connecting pipe is communicated with the side of the second cylinder away from the placement box, and the other end passes through the bottom of the mounting frame shell and is communicated with the bottom of the first cylinder.

[0044] When the circuit breaker needs to be moved down, the two movable rods drive the two sliding plates to move toward each other, and the two third springs gradually reset. The two third springs drive the second piston to approach the placement box. After the two third springs are completely reset, the second piston also moves to the side inner wall of the second cylinder body close to the placement box. Then, when the two sliding plates continue to move toward each other, the sliding plates will stretch the second telescopic rod.

[0054] The axis of the fan coincides with the axis of the rotating shaft of the first motor. The fan is arranged inside the mounting frame shell, on the side of the first motor away from the placement box, and is sleeved on the outside of the rotating shaft of the first motor. The fan is fixedly connected to the rotating shaft of the first motor, and its rotation axis coincides with its own axis.

[0056] The switch is arranged inside the second groove, the switch is fixedly connected to the inner top surface of the second groove, and the switch is used to control the start and stop of the first motor.

[0057] The axis of the vertical rod coincides with the axis of the first cylinder body, and is arranged at the lower part of the second groove and above the fixed plate. The lower end of the vertical rod is fixedly connected to the top of the fixed plate.

[0058] When the circuit breaker needs to be cooled, the mounting plate continues to move downward relative to the fixed plate, and the mounting plate drives the switch to move downward relative to the fixed plate, so that the vertical rod contacts and presses the switch, and the switch transmits a signal to the controller, and then the controller controls the first motor to start, and the shaft of the first motor drives the fan to rotate. The rotation of the fan accelerates the air flow around the circuit breaker to cool the circuit breaker.

[0059] When there is no need to dissipate heat for the circuit breaker, the mounting plate moves up relative to the fixed plate, and the mounting plate drives the switch to move up relative to the fixed plate, so that the switch is away from the vertical rod and the pressed state is released, and the switch transmits a signal to the controller, and the controller controls the first motor to stop working, thereby saving energy.

[0060] Furthermore, the placement box and the plug rod are fixedly connected by bolts.

[0106] The two third springs 22 are respectively arranged inside the second cylinder body 19, on the side of the second piston 20 away from the placement box 18, and are respectively sleeved on the outside of the two first telescopic rods 21. One end of the two third springs 22 is respectively fixedly connected to the inner wall of the second cylinder body 19, and the other end is respectively fixedly connected to the second piston 20.

[0109] When the circuit breaker needs to be moved down, the two movable rods 11 drive the two sliding plates 10 to move toward each other, and the two third springs 22 gradually reset. The two third springs 22 drive the second piston 20 to approach the placement box 18. After the two third springs 22 are completely reset, the second piston 20 also moves to the side inner wall of the second cylinder 19 close to the placement box 18. Then, when the two sliding plates 10 continue to move toward each other, the sliding plates 10 will stretch the second telescopic rod 23.

[0110] When the two third springs 22 drive the second piston 20 to approach the placement box 18, the first piston 16 moves downward, the first piston 16 drives the plug rod 17 downward, the plug rod 17 drives the placement box 18 downward, and the placement box 18 drives the circuit breaker downward, so that the top of the placement box 18 is at the same level as the inner bottom surface of the mounting frame housing 1.

[0111] When the circuit breaker needs to be moved up and taken out, the two movable rods drive the two sliding plates 10 to move in the opposite direction. The sliding plate 10 first drives the second telescopic rod 23 to retract. After the second telescopic rod 23 is completely retracted, the sliding plate 10 drives the second telescopic rod 23 away from the placement box 18. The second telescopic rod 23 drives the second piston 20 away from the placement box 18, and the second piston 20 compresses the two third springs 22.

[0112] When the second telescopic rod 23 drives the second piston 20 away from the placement box 18, the first piston 16 moves upward, the first piston 16 drives the plug rod 17 upward, the plug rod 17 drives the placement box 18 upward, and the placement box 18 drives the circuit breaker upward, so that the staff can take the circuit breaker out of the opening of the placement box 18 without pulling the circuit breaker upward, which is more convenient.

[0113] The second telescopic rod 23 and the sliding plate 10 are fixedly connected by welding.

[0114] This enables the sliding plate 10 to stably drive the second telescopic rod 23 to retract.

[0115] The connecting pipe 24 is made of a hose.

[0117] The heat dissipation device includes a first motor 25 , a fan 26 , a second groove 27 , a switch 28 , and a vertical rod 29 .

[0118] The first motor 25 has a rotating shaft axis parallel to the axis of the second cylinder 19 and is disposed inside the mounting frame housing 1 , on the side of the sliding plate 10 away from the placement box 18 . The housing of the first motor 25 is fixedly connected to the side of the sliding plate 10 .

[0119] The axis of the fan 26 coincides with the axis of the rotating shaft of the first motor 25. The fan 26 is arranged inside the mounting frame housing 1, on the side of the first motor 25 away from the placement box 18, and is sleeved on the outside of the rotating shaft of the first motor 25. The fan 26 is fixedly connected to the rotating shaft of the first motor 25, and its rotation axis coincides with its own axis.

[0122] The axis of the vertical rod 29 coincides with the axis of the first cylinder body 15 , and is disposed at the lower part of the second groove 27 , above the fixing plate 6 , and the lower end of the vertical rod 29 is fixedly connected to the top of the fixing plate 6 .

[0123] When the circuit breaker needs to be cooled, the mounting plate 4 continues to move downward relative to the fixing plate 6, and the mounting plate 4 drives the switch 28 to move downward relative to the fixing plate 6, and then the vertical rod 29 contacts and presses the switch 28, and the switch 28 transmits a signal to the controller 30, and then the controller 30 controls the first motor 25 to start, and the rotating shaft of the first motor 25 drives the fan 26 to rotate, and the rotation of the fan 26 accelerates the air flow around the circuit breaker to cool the circuit breaker.

[0124] When there is no need to dissipate heat for the circuit breaker, the mounting plate 4 moves upward relative to the fixing plate 6, and the mounting plate 4 drives the switch 28 to move upward relative to the fixing plate 6, so that the switch 28 moves away from the vertical rod 29, and the pressed state is released, and the switch 28 transmits a signal to the controller 30, and the controller 30 controls the first motor 25 to stop working, thereby saving electric energy.

[0125] The placement box 18 and the plug rod 17 are fixedly connected by bolts.

[0126] The placement box 18 can be replaced conveniently.

[0127] The bottom of the fixing plate 6 , the opposite sides of the two clamping plates 13 , and the inner wall of the placement box 18 are all provided with an insulating layer.

[0128] Prevent the current of the circuit breaker from being transmitted through the fixing plate 6, the clamping plate 13, and the placement box 18.

[0129] Working principle: when installing the circuit breaker on the mounting frame, the staff places the bottom of the circuit breaker in the placement box 18, and then the staff controls the telescopic rod of the cylinder 3 to move downward through the controller 30, and the telescopic rod of the cylinder 3 drives the two movable rods 11 to contract, drives the mounting plate 4 to move downward, and the mounting plate 4 drives the first springs 5 ​​to move downward, and the first springs 5 ​​drive the fixing plate 6 to move downward. After the fixing plate 6 contacts the top of the circuit breaker, the mounting plate 4 continues to move downward relative to the fixing plate 6, and then the first springs 5 ​​contract, so that the fixing plate 6 fixes the circuit breaker.

[0130] When the telescopic rod of the cylinder 3 drives the two movable rods 11 to contract, the two movable rods 11 drive the two sliding plates 10 to move toward each other, the two sliding plates 10 drive the plurality of second springs 12 to move toward each other, the plurality of second springs 12 drive the two clamping plates 13 to move toward each other, after the two clamping plates 13 contact the two sides of the circuit breaker, the two sliding plates 10 continue to move toward each other relative to the two clamping plates 13, and then the plurality of second springs 12 contract, so that the two clamping plates 13 clamp and fix the circuit breaker.

[0131] When the two movable rods 11 drive the two sliding plates 10 to move toward each other, the two third springs 22 gradually reset, and the two third springs 22 drive the second piston 20 to approach the placement box 18. After the two third springs 22 are completely reset, the second piston 20 also moves to the side inner wall of the second cylinder 19 close to the placement box 18. When the two sliding plates 10 continue to move toward each other, the sliding plates 10 will stretch the second telescopic rod 23.

[0132] When the two third springs 22 drive the second piston 20 to approach the placement box 18, the first piston 16 moves downward, the first piston 16 drives the plug rod 17 downward, the plug rod 17 drives the placement box 18 downward, and the placement box 18 drives the circuit breaker downward, so that the top of the placement box 18 is at the same level as the inner bottom surface of the mounting frame housing 1.

[0133] When the mounting plate 4 continues to move downward relative to the fixed plate 6, the mounting plate 4 drives the switch 28 to move downward relative to the fixed plate 6, and then the vertical rod 29 contacts and presses the switch 28, and the switch 28 transmits a signal to the controller 30, and then the controller 30 controls the first motor 25 to start, and the rotating shaft of the first motor 25 drives the fan 26 to rotate, and the rotation of the fan 26 accelerates the air flow around the circuit breaker to dissipate heat for the circuit breaker.

[0134] When the circuit breaker needs to be taken out for maintenance, the staff controls the telescopic rod of the cylinder 3 to move up through the controller 30, and the telescopic rod of the cylinder 3 drives the two movable rods 11 to open, and drives the mounting plate 4 to move up. The mounting plate 4 first moves up relative to the fixed plate 6. After the first springs 5 ​​are reset, the mounting plate 4 drives the first springs 5 ​​to move up, and the first springs 5 ​​drive the fixed plate 6 to move up, thereby releasing the fixation of the circuit breaker.

[0135] When the telescopic rod of the cylinder 3 drives the two movable rods 11 to open, the two movable rods 11 drive the two sliding plates 10 to move in the opposite direction, and the two sliding plates 10 first move in the opposite direction relative to the two clamping plates 13. After the second springs 12 are reset, the two sliding plates 10 drive the second springs 12 to move in the opposite direction, and the second springs 12 drive the two clamping plates 13 to move in the opposite direction, thereby releasing the clamping fixation of the circuit breaker.

[0136] When the two movable rods 11 drive the two sliding plates 10 to move in opposite directions, the sliding plate 10 first drives the second telescopic rod 23 to retract. After the second telescopic rod 23 has completed its retraction, the sliding plate 10 drives the second telescopic rod 23 away from the placement box 18, and the second telescopic rod 23 drives the second piston 20 away from the placement box 18, and the second piston 20 compresses the two third springs 22.

[0137] When the second telescopic rod 23 drives the second piston 20 away from the placement box 18, the first piston 16 moves upward, the first piston 16 drives the plug rod 17 upward, the plug rod 17 drives the placement box 18 upward, and the placement box 18 drives the circuit breaker upward, so that the staff can take the circuit breaker out of the opening of the placement box 18 without pulling the circuit breaker upward, which is more convenient.

[0138] When the mounting plate 4 moves upward relative to the fixing plate 6, the mounting plate 4 drives the switch 28 to move upward relative to the fixing plate 6, and then the switch 28 moves away from the vertical rod 29, and the pressed state is released, and then the switch 28 transmits a signal to the controller 30, and then the controller 30 controls the first motor 25 to stop working, thereby saving energy.
