Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker testing, in particular to a device for measuring the mechanical force of an opening and closing coil. Background Art

[0002] Circuit breakers provide overload, short-circuit, and undervoltage protection, safeguarding both circuits and power supplies. The term "circuit breaker" derives from the fact that both the arc-extinguishing medium and the insulating medium in the contact gap after arc extinguishing are both high vacuum. They are compact, lightweight, suitable for frequent operation, and require no maintenance after arc extinguishing, making them widely used in distribution networks.

[0003] After searching, the Chinese utility model patent with publication number CN208125315U discloses a mechanical force measuring device for an opening and closing coil, which relates to the field of circuit breaker testing. The mechanical force measuring device for an opening and closing coil includes a base, on which a force measuring device and an opening and closing coil fixing part are provided. The force measuring device is fixed to the base, and the opening and closing coil fixing part is fixedly connected to the base; the surface area of ​​the opening and closing coil fixing part is adjustable, the opening and closing coil is fixed on the opening and closing coil fixing part, and the detection end of the force measuring device is located in the moving direction of the push rod in the opening and closing coil.

[0004] However, in the above-mentioned comparative documents, each time during testing, the opening and closing coils need to be fixed on the coils by tightening the cable ties. This operation greatly reduces the efficiency of testing during large-scale testing. At the same time, after each test, the cable ties need to be manually removed, and the tested opening and closing coils need to be removed. The opening and closing coils are placed in the corresponding collection box according to the test results. This operation greatly increases the labor intensity of workers during large-scale testing. Utility Model Content

At the same time, after the opening and closing coils are detected, the rotating rod and the push plate rotate clockwise or counterclockwise to push the detected opening and closing coils into the corresponding collection frame, thereby greatly reducing the labor intensity of workers.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The front and rear sides of the placement plate 9 are provided with a snap assembly, the upper end of the base 1 is provided with a sorting assembly, the front and rear inner walls of the transverse groove 2 are fixedly connected to two limit blocks 8, the lower end of the base 1 is fixedly connected to a plurality of support columns, and the front and rear sides of the base 1 are provided with a collection frame 11. The force measuring device 12 is provided with a sensor, and the base 1 is provided with a controller. The sensor will transmit an electrical signal to the controller, and the controller controls the clockwise or counterclockwise rotation of the motor 4.

[0022] Among them, the snap-fit ​​assembly includes square grooves 19 arranged on the front and rear sides of the placement plate 9, and electromagnets 17 are provided in the two square grooves 19. Through openings 21 are provided on the front and rear sides of the base 1. There are blocks 20 slidingly connected in the two square grooves 19. The two blocks 20 are elastically connected to the adjacent surfaces of the corresponding electromagnets 17 through springs 18. The sides of the two blocks 20 away from the corresponding square grooves 19 are both semicircular, and the materials of the two blocks 20 are both magnetic materials.

[0023] Among them, the sorting component includes a vertical rod 3 fixedly connected to the upper end of the base 1, the right side of the vertical rod 3 is rotatably connected to the rotating rod 5, the upper end of the rotating rod 5 is fixedly connected to the push plate 6, the left side of the vertical rod 3 is installed with a motor 4, the left side of the rotating rod 5 passes through the vertical rod 3 and is fixedly connected to the output shaft of the motor 4.

[0024] The functional principle of the present invention can be explained through the following operation mode: the opening and closing coil to be measured is placed on the placement plate 9, and the opening and closing coil is pressed, which drives the placement plate 9 to move downward, so that the two blocks 20 slide into the corresponding openings 21 under the elastic action of the spring 18. At this time, the two folded airbags 10 are compressed, so that the air in the two folded airbags 10 enters the corresponding arc-shaped airbags 14 through the connecting tube 16, thereby driving the pressing plate 1 7 and the pressing plate 2 13 to rotate clockwise, pressing the opening and closing coil;

[0025] At this time, the opening and closing coils are energized for testing. After the test is completed, the two electromagnets 17 are energized. Since the two blocks 20 are made of magnetic material, the two blocks 20 slide into the corresponding square grooves 19. At this time, the two folding airbags 10 are stretched, so that the air in the two arc-shaped airbags 14 returns to the corresponding folding airbags 10 through the connecting tubes 16, thereby causing the pressure plate 1 7 and the pressure plate 2 13 to rotate counterclockwise. When the folding airbags 10 are stretched, the placement plate 9 and the opening and closing coils are moved upward;

[0026] After the test is completed, if the opening and closing coil is faulty, the sensor will transmit an electrical signal to the controller, and the controller will control the motor 4 to rotate clockwise, driving the rotating rod 5 and the push plate 6 to rotate clockwise, thereby pushing the opening and closing coil into the collection frame 11 at the rear side. If the opening and closing coil is not faulty, the controller will control the motor 4 to rotate counterclockwise, thereby pushing the opening and closing coil into the collection frame 11 at the front side.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
