[0002] 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. After production, circuit breakers must be tested to ensure they are capable of interrupting currents properly, which requires a test bench.

The detection device is arranged on the upper side of the test slot. The test slot is used to detect short circuit breakers, and the size of the test slot is the same as that of the circuit breaker. It can correspond to the position where the electrode is connected when the circuit breaker falls into the test slot. When the circuit breaker is in the test slot, the electric push rod pushes the connecting block and the electrode connected to it to move, and stops when the electrode is connected to the power connection on the circuit breaker for detection.

[0004] The test bench detects the circuit breaker by moving the electrode, and the circuit breaker is placed in the test slot, so that the circuit breaker is not stable enough when the electrode contacts the circuit breaker, and the circuit breaker is prone to shaking or displacement, making the test result inaccurate.

[0018] A second motor is fixedly connected to the top surface of the box body, and a top end of one of the first gears is fixedly connected to the output shaft of the second motor.

[0019] Furthermore, the elastic member includes a telescopic rod and a spring, the spring is sleeved on the telescopic rod, one end of the spring and the telescopic rod are fixedly connected to one side of the movable plate, and the other end of the spring and the telescopic rod are fixedly connected to one side of the corresponding limit plate.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The circuit breaker intelligent test bench is equipped with a limit plate, which is connected to the movable plate through an elastic member. The tooth plate moves closer to each other, driving the movable plate and the limit plate to move, so that the limit plate contacts the circuit breaker to be tested. Then, the movable plate continues to move, squeezing the limit plate through the elastic member, so that the limit plate abuts against the circuit breaker, thereby clamping and fixing the circuit breaker. This reduces displacement or shaking of the circuit breaker during testing, making the test results more accurate.

[0029] 2. The circuit breaker intelligent testing platform is equipped with four tooth plates.

After the circuit breaker is fixed by the movable plate, the tooth plates continue to move, and the movable plate continues to squeeze the elastic member, which can move the electrode to the circuit breaker for testing. There is no need to drive the movable plate and the electrode separately, which simplifies operation and reduces production costs.

[0030] 3. The circuit breaker intelligent test bench is equipped with a flap, which is rotated in the through-hole on the top surface of the box. The circuit breaker is fixed on the top of the two flaps for testing. After the test is completed, the four tooth plates move away from each other, which will drive the limit rod to slide inside the guide groove. When the limit rod slides in the inclined section of the guide groove, it will drive the rotating rod to rotate, causing the flap to rotate, so that the circuit breaker on the flap falls into the box, thereby automatically collecting the circuit breaker.

[0031] 4. The circuit breaker intelligent test bench is equipped with a movable door, which is rotated in a window on the side of the box. When the tooth plate moves, it can drive the second gear to rotate, and the fourth gear and the rotating shaft are rotated through the transmission of the third gear, so that the movable door rotates, and then the movable door can be automatically opened and closed, with a high degree of automation.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] like Figures 1-8 As shown, the technical solution adopted by the present invention is as follows: an intelligent circuit breaker testing platform, comprising two support frames 1 and a housing 7. A conveyor belt 2 is provided at the top between the two support frames 1, with one end of the conveyor belt 2 positioned directly above the middle of the housing 7. The conveyor belt 2 transports the circuit breaker to the top of the housing 7.

[0043] Both support frames 1 are L-shaped and symmetrically arranged. The two support frames 1 are secured together by a crossbar. Two fixing seats 26 are symmetrically fixed to the top of one of the support frames 1. Several fixing cylinders 3 are fixedly connected between the two fixing seats 26 at intervals. The fixing cylinders 3 are fixedly connected to the top of the support frame 1.

[0044] A connecting rod 5 is rotatably connected between the two fixing seats 26, and the connecting rod 5 rotates and penetrates a plurality of fixing cylinders 3. The connecting rod 5 is arranged along the moving direction of the top of the conveyor belt 2.

[0045] A baffle 6 is fixedly mounted on the outer surface of the connecting rod 5 between the two fixed cylinders 3. A baffle 6 is also installed between the fixed cylinder 3 at each end and the corresponding fixed seat 26. The baffle 6 is movably mounted on top of the conveyor belt 2. The baffle 6 divides the space above the conveyor belt 2, allowing the circuit breaker to be located between two adjacent baffles 6.

[0046] A first motor 4 is fixedly connected to one side of one of the fixing bases 26, which drives the connecting rod 5 to rotate. One end of the connecting rod 5 rotates through the fixing base 26 and is fixedly connected to the output shaft of the first motor 4, so that the connecting rod 5 drives the baffle 6 to rotate, facilitating the transportation of circuit breakers one by one.

[0047] The middle part of the four sides of the top of the box body 7 is slidably provided with a tooth plate 11, and the four tooth plates 11 are distributed in a circumferential array about the middle part of the box body 7. A driving assembly is provided inside the box body 7, which drives the four tooth plates 11 to slide toward or away from each other.

[0048] A through hole is provided in the middle of the top surface of the box body 7, and a sliding groove is provided on the side surface of the through hole at each tooth plate 11, and the tooth plate 11 is slidably arranged in the corresponding sliding groove. The tooth plate 11 is positioned by the sliding groove.

[0049] The corresponding two tooth plates 11 form a group, so that the two tooth plates 11 in a group are not adjacent. A movable plate 13 is fixedly connected to the top of the adjacent ends of the tooth plates 11 in the first group. The adjacent sides of the two movable plates 13 are connected to a limit plate 15 via an elastic member 14. Movement of the tooth plates 11 drives the movement of the movable plate 13, the elastic member 14, and the limit plate 15.

[0050] The elastic member 14 comprises a telescopic rod and a spring, which is sleeved onto the telescopic rod. One end of the spring and the telescopic rod are both fixedly connected to one side of the movable plate 13, while the other ends of the spring and the telescopic rod are both fixedly connected to one side of the corresponding stop plate 15. In the initial state, the spring pushes the telescopic rod to its maximum extension, maximizing the distance between the movable plate 13 and the stop plate 15.

[0051] Electrodes 12 are fixedly connected to the tops of the adjacent ends of the second set of toothed plates 11. By moving electrodes 12 to the power connection on the circuit breaker, a detection device, as disclosed in patent CN222343504U mentioned in the background, is installed on housing 7 to perform circuit breaker testing. The relevant structure for circuit breaker testing is consistent with that in patent CN222343504U, and the detection principle is already disclosed in that patent. This is prior art and will not be elaborated on here.

[0052] A window is provided on the side of the box body 7 at one of the electrodes 12, and a movable door 22 is provided inside the window so that the corresponding tooth plate 11 slides on the top of the movable door 22.

[0053] The other three inner walls of the box body 7 are fixedly connected with fixing plates 27 , and the top surface of each fixing plate 27 is provided with an arc-shaped positioning groove.

[0054] The drive assembly includes a gear ring 10, which is rotatably connected to the inside of the three positioning grooves. The top surface of the gear ring 10 slides with the bottom surface of the tooth plate 11, and the gear ring 10 is positioned in the box body 7 through the positioning grooves and the tooth plate 11.

[0055] Four first gears 9 are connected to the top surface of the housing 7 for uniform rotation. Each of these first gears 9 corresponds to a toothed plate 11. The tops of the first gears 9 mesh with their corresponding toothed plates 11. Each of the four first gears 9 is located within a gear ring 10, and the bottoms of each first gear 9 mesh with the gear ring 10. When the gear ring 10 rotates, it drives all of the first gears 9 to rotate synchronously, driving the corresponding gear ring 10 to move.

[0056] A second motor 8 is fixedly connected to the top surface of the box body 7, and the top end of one of the first gears 9 is fixedly connected to the output shaft of the second motor 8. As long as one of the first gears 9 rotates, all the first gears 9 are rotated through the transmission of the gear ring 10.

[0057] The top of the movable door 22 has a groove, through which a vertically extending rotating shaft 28 is fixed. Both the top and bottom ends of the rotating shaft 28 are rotatably connected to the housing 7. A fourth gear 21 is fixedly mounted on the outer surface of the rotating shaft 28 within the groove. The rotating shaft 28 positions the movable door 22 on the housing 7, allowing the movable door 22 to rotate about its axis of rotation.

[0058] The top surface of the window is rotatably connected to a third gear 20 and a second gear 19. These three gears are arranged in a straight line. The third gear 20 meshes with the second and fourth gears 19, 21, which in turn mesh with the corresponding toothed plate 11. Movement of the toothed plate 11 drives the second gear 19, which in turn rotates the third and fourth gears 20, 21, and thus the rotating shaft 28 and the movable door 22.

[0059] Two flaps 17 are symmetrically connected to the middle of the top surface of the box 7. Both flaps 17 are rotatably arranged in the through holes on the top surface of the box 7. The circuit breakers transported by the conveyor belt 2 fall onto the two flaps 17. When the flaps 17 rotate, the circuit breakers fall through the through holes into the box 7.

[0060] The ends of the tooth plates 11 of the first group that are away from each other are both provided with transmission members, and the two transmission members cooperate to drive the two flaps 17 to rotate.

[0061] The transmission member includes a limit rod 16, which is arranged horizontally. The limit rod 16 is fixed through the tooth plate 11, and both ends of the limit rod 16 are provided with rounded corners. When the tooth plate 11 moves, the limit rod 16 is driven to move.

[0062] The rotating ends of the two flaps 17 are fixed with connecting shafts 29, which are respectively located at the two ends of the through hole to facilitate the circuit breaker to fall down from between the two flaps 17. A sponge pad is placed on the bottom surface of the box body 7 to protect the circuit breaker.

[0063] Both ends of the connecting shaft 29 rotate through the top surface of the housing 7 and are coaxially fixedly connected to the rotating rod 18. The rotating rod 18 is rotatably mounted outside the housing 7. Each rotating rod 18 has a guide groove 32 defined on its outer surface, and the end of the limiting rod 16 slides into the corresponding guide groove 32. The two guide grooves 32 are symmetrically arranged on the same side of the housing 7.

[0064] The guide groove 32 consists of a horizontal section and an inclined section, with the inclined end located at the end away from the box body 7. When the limit rod 16 slides in the horizontal section, it does not drive the rotating rod 18 to rotate. When the limit rod 16 slides in the inclined section, it drives the rotating rod 18 to rotate, and the two rotating rods 18 at both ends of the limit rod 16 rotate in opposite directions.

[0065] The top of the box body 7 is symmetrically fixedly connected to two inverted U-shaped mounting brackets 23, the tops of the two mounting brackets 23 are slidably connected to sliders 31, and a lever 25 is fixedly connected between the two sliders 31. The lever 25 is located above the electrode 12, the movable plate 13, and the limit plate 15.

[0066] A screw rod 24 is rotatably connected to the top of one of the mounting brackets 23, and a slider 31 is threadedly mounted on the screw rod 24. A third motor 30 is fixedly connected to one end of the mounting bracket 23. One end of the screw rod 24 rotates through the end surface of the mounting bracket 23 and is fixedly connected to the output shaft of the third motor 30. The third motor 30 drives the screw rod 24 to rotate, which in turn drives one of the sliders 31 connected to it, thereby driving the lever 25 and the other slider 31 to move.

[0067] Working principle:

[0068] When in use, the circuit breaker to be tested is placed on the top of the conveyor belt 2 and located between two adjacent baffles 6 .

[0069] The first motor 4 is started, and the output terminal of the first motor 4 rotates forward. This drives the connecting rod 5 to rotate, which in turn rotates the baffle 6 away from the conveyor belt 2. At this point, the conveyor belt 2 can be started, which drives the circuit breaker to move. The circuit breaker at the end is transferred downward to the top of the two flaps 17.

[0070] Afterwards, the output shaft of the first motor 4 is reversed, and the connecting rod 5 is rotated to rotate the baffle 6 to the top of the conveyor belt 2. The circuit breaker is continued to be located between two adjacent baffles 6 to position the circuit breaker.

[0071] The circuit breaker that falls on the two flaps 17 will be located between the two limit plates 15 and between the two electrodes 12. If the position of the circuit breaker is not accurate, the staff will adjust the circuit breaker so that the power interface of the circuit breaker corresponds to the two electrodes 12 one by one.

[0072] When the second motor 8 is started, its output terminal rotates forward, driving a first gear 9 connected to it. This first gear 9 then drives a gear ring 10, which in turn drives the remaining first gears 9. The first gear 9 simultaneously drives the toothed plates 11 to slide within their corresponding slots, with the four toothed plates 11 sliding toward each other.

[0073] The first set of toothed plates 11 drives the movable plate 13, the elastic member 14, and the limit plate 15 to move, so that the two limit plates 15 approach each other. The second set of toothed plates 11 drives the electrodes 12 to move, so that the two electrodes 12 approach each other and move toward the power interface of the circuit breaker.

[0074] The limit plate 15 will first contact the circuit breaker, and then the movable plate 13 pushes one end of the elastic member 14. The elastic member 14 is compressed, thereby exerting a thrust on the limit plate 15, which abuts the limit plate 15 on the circuit breaker, and the circuit breaker is fixed by the cooperation of the two limit plates 15.

[0075] At this time, the end of the limiting rod 16 slides in the horizontal section of the guide groove 32, and will not drive the rotating rod 18 to rotate, and the flap 17 will not rotate.

[0076] One of the gear plates 11 drives the second gear 19 to rotate, the second gear 19 drives the third gear 20 to rotate, and the third gear 20 drives the fourth gear 21 to rotate, so as to rotate the rotating shaft 28 and the movable door 22.

[0077] After that, the tooth plate 11 continues to move, so that the clamping force of the limit plate 15 on the circuit breaker is greater, until the electrode 12 is moved to fit the power interface of the circuit breaker. The movable door 22 rotates to seal the window on the side of the box body 7.

[0078] The movement of the tooth plate 11 drives the limit plate 15 and the electrode 12 to work respectively, without the need to drive them separately, thereby reducing production costs. At the same time, there is no need for workers to connect the circuit breaker to electricity separately, thereby achieving the purpose of intelligent detection.

[0079] The third motor 30 is started to rotate the screw rod 24. The screw rod 24 drives the slider 31 connected thereto to move, so that the slider 31 slides on the corresponding mounting bracket 23. The lever 25 and the other slider 31 are driven to move, so that the lever 25 toggles the switch on the circuit breaker.

[0080] The detection device disclosed in the patent CN222343504U mentioned in the background art is installed on the box 7, and the circuit breaker is detected by cooperating with the electrode 12. The principle of detecting the circuit breaker is described in detail in the patent and will not be elaborated here.

[0081] After the circuit breaker is inspected, the output end of the second motor 8 is reversed to drive the four tooth plates 11 to move in opposite directions.

[0082] The first set of toothed plates 11 drives the movable plate 13 to move. Since the elastic member 14 is in a compressed state, the elastic member 14 stretches and continues to abut the limit plate 15 against the circuit breaker. The second set of toothed plates 11 drives the electrode 12 to move, so that the electrode 12 moves away from the circuit breaker.

[0083] At this time, the end of the limiting rod 16 slides in the horizontal section of the guide groove 32, and will not drive the rotating rod 18 to rotate, and the flap 17 will not rotate.

[0084] After the elastic member 14 returns to its natural state, the movable plate 13 drives the elastic member 14 and the limiting plate 15 to move, so that the limiting plate 15 leaves the circuit breaker.

[0085] The end of the limiting rod 16 then slides into the inclined section of the guide slot 32. Since the limiting rod 16 can only slide horizontally, it pushes the rotating rod 18 to rotate, with the two rotating rods 18 at both ends of the limiting rod 16 rotating in opposite directions. This causes the connecting shaft 29 and the flap 17 to rotate, with the two flaps 17 rotating in opposite directions, causing the circuit breaker to fall downward between the two flaps 17 into the housing 7.

[0086] Simultaneously, one of the toothed plates 11 drives the second gear 19 to rotate, thereby rotating the movable door 22. This allows the circuit breaker in the housing 7 to be taken out through the movable door 22.

[0087] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
