[0001] This utility model belongs to the field of monitoring device technology, specifically a circuit breaker status monitoring device. Background Technology

[0002] Circuit breaker condition monitoring devices belong to the field of power measurement instruments or power electronics technology. They are mainly used to monitor the switching status and other related parameters of circuit breakers in real time. Through this device, the operating status of the circuit breaker can be understood in a timely manner, preventing potential faults and improving the stability and safety of the power system. The circuit breaker condition monitoring device includes an input circuit, a resistor divider circuit, a voltage regulator circuit, and a signal output circuit. These circuits are interconnected to jointly realize the circuit breaker condition monitoring function. The monitoring device receives signals from the circuit breaker through the input circuit. After processing by the resistor divider and voltage regulator circuits, a stable signal is output by the signal output circuit. This signal reflects the switching status of the circuit breaker and is used by subsequent switching quantity monitoring equipment. Circuit breaker condition monitoring devices are widely used in various occasions requiring monitoring of circuit breaker status, such as substations, distribution rooms, factory workshops, and mining enterprises. In these occasions, the circuit breaker condition monitoring device can monitor the operating status of the circuit breaker in real time, preventing faults and improving the reliability and safety of the power system. Existing circuit breaker condition monitoring devices are usually fixed and assembled using multiple screws, requiring tools to remove them one by one, making maintenance very inconvenient. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a circuit breaker condition monitoring device, which effectively solves the problem that the existing circuit breaker condition monitoring devices are usually fixed and assembled with multiple screws, which requires tools to remove them one by one, making maintenance very inconvenient.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a circuit breaker status monitoring device, comprising a first housing, a second housing on one side of the first housing, insert rods fixedly installed at the four corners of the first housing near the second housing, support frames fixedly installed on both sides of the bottom of the second housing, insertion holes opened at the four corners of the second housing near the first housing, four locking holes opened on both sides of the first and second housings respectively, locking rods inserted into the eight locking holes, a turntable on the side of the second housing away from the first housing, a transmission assembly on one side of the turntable, the transmission assembly being connected to the eight locking rods in a transmission connection, when the turntable rotates, power is output to the eight locking rods through the transmission assembly, causing the eight locking rods to exit the eight locking holes and release their limiting positions.

[0005] Preferably, the transmission assembly includes a transmission bar with one end of a turntable fixedly mounted on it. The middle part of one side of the transmission bar is rotatably connected to the second housing via a bearing seat. A movable rod is movably inserted into the upper part of the transmission bar. A pull ring is fixedly mounted on one end of the movable rod, and a pushing plate is fixedly mounted on the other end of the movable rod. A spring is sleeved on the surface of the movable rod, and both ends of the spring are fixedly connected to the pushing plate and the transmission bar, respectively. A limit rod is fixedly mounted on one side of the pushing plate. A groove is formed in the middle of the side of the second housing away from the first housing. A first and second limiting holes are formed in the upper part of the groove. The limiting rod is inserted into the second limiting hole. A first limiting hole is formed on one side of the groove.

[0006] Preferably, push-pull bars are rotatably installed at both ends of the transmission bar, and connecting bars are rotatably installed at the ends of the two push-pull bars that are far apart from each other. A movable plate is fixedly installed at one end of each of the two connecting bars, and the four corners of the two movable plates that are close to each other are respectively fixedly connected to eight clamps.

[0007] Preferably, a sliding sleeve is fixedly installed on one side of the movable plate by a fixing head, and a sliding rod is inserted into the inside of each sliding sleeve. The ends of the two sliding rods that are close to each other are fixedly connected to the second housing by an installation strip.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: During maintenance, the operator pulls the moving rod through the pull ring. When the moving rod moves, it drives the limiting rod to exit the second limiting hole through the pushing plate to release the limit, and at the same time, it squeezes the spring. Then, the operator drives the transmission bar to rotate 90° through the turntable. When the transmission bar rotates, it pushes the two connecting bars to move in opposite directions through the two push-pull bars. When the two connecting bars move in opposite directions, they drive the two moving plates to move in opposite directions. When the two moving plates move, they drive the sliding sleeve to slide on the surface of the sliding rod through the fixed head, which increases the stability of the two moving plates when they move. When the two moving plates move in opposite directions, they drive the eight locking rods to exit the eight locking holes to release the limit.

[0009] The operator then separates the first and second housings and simultaneously removes the four insertion rods from the four insertion holes, thus quickly completing the disassembly. As the transmission bar rotates 90°, it drives the limiting rod to rotate to the position of the first limiting hole. Under the elastic force of the spring, the limiting rod is pushed into the first limiting hole for limiting, thereby achieving self-locking and ensuring stability. This makes the disassembly of the circuit breaker condition monitoring device very convenient, thereby reducing the workload of maintenance personnel and improving work efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

A turntable 9 is provided on the side of the second housing 2 away from the first housing 1, and a transmission assembly is provided on one side of the turntable 9. The transmission assembly is connected to the eight locking rods 6. When the turntable 9 rotates, the power is output to the eight locking rods 6 through the transmission assembly, causing the eight locking rods 6 to exit the eight locking holes 7 and release their restraints.

[0021] During maintenance, the operator adjusts the transmission component by pulling ring 22. When the transmission component is running, it will drive the eight locking rods 7 to disengage from the eight locking holes 6 and release the limit. Then the operator separates the first housing 1 and the second housing 2, and at the same time, the four plug rods 4 disengage from the four plug holes 5, thereby quickly completing the disassembly. This makes the disassembly of the circuit breaker condition monitoring device very convenient, thereby reducing the workload of maintenance personnel and improving work efficiency.

[0022] The transmission assembly includes a transmission bar 10, one end of which is fixedly mounted with a turntable 9. The middle part of one side of the transmission bar 10 is rotatably connected to the second housing 2 via a bearing seat 11. A moving rod 21 is movably inserted into the upper part of the transmission bar 10. A pull ring 22 is fixedly mounted at one end of the moving rod 21, and a pushing plate 23 is fixedly mounted at the other end of the moving rod 21.

A first and second limit holes 20 are opened in the upper part of the groove 18. The limit rod 24 is inserted into the second limit hole 20. A first limit hole 19 is opened in one side of the groove 18.

[0023] The operator pulls the moving rod 21 through the pull ring 22. When the moving rod 21 moves, it drives the limiting rod 24 out of the second limiting hole 20 through the pushing plate 23 to release the limit, and at the same time, it squeezes the spring 14.

[0024] As the transmission bar 10 rotates 90°, it will drive the limiting rod 24 to rotate to the position of the first limiting hole 19. Under the elastic force of the spring 14, the limiting rod 24 will be pushed into the interior of the first limiting hole 19 for limiting, thereby achieving self-locking and ensuring stability.

[0025] Push-pull bars 12 are rotatably mounted at both ends of the transmission bar 10. Connecting bars 13 are rotatably mounted at the ends of the two push-pull bars 12 that are far apart from each other. Movable plates 8 are fixedly mounted at one end of the two connecting bars 13. The four corners of the two movable plates 8 that are close to each other are fixedly connected to eight locking rods 6 respectively. Sliding sleeves 16 are fixedly mounted on one side of the movable plates 8 through fixing heads 15. Sliding rods 17 are inserted into the inside of the sliding sleeves 16. The ends of the two sliding rods 17 that are close to each other are fixedly connected to the second housing 2 through mounting bars.

[0026] When the transmission bar 10 rotates, it pushes the two connecting bars 13 to move in opposite directions through the two push-pull bars 12. When the two connecting bars 13 move in opposite directions, they drive the two moving plates 8 to move in opposite directions. When the two moving plates 8 move, they drive the sliding sleeve 16 to slide on the surface of the sliding rod 17 through the fixed head 15, which increases the stability of the two moving plates 8 when they move. When the two moving plates 8 move in opposite directions, they drive the eight locking rods 7 to exit the interior of the eight locking holes 6 and release the limit.
