Description

Technical Field

[0001] This invention belongs to the field of mechanical transmission technology, and more specifically, relates to an electric operating device drive transmission mechanism. Background Technology

[0002] In the circuit control system of power systems, the circuit breaker drive transmission mechanism is a key core component that ensures the accuracy of circuit switching and the stability of system operation. Its performance directly affects the continuity and safety of power supply. However, the drive transmission mechanisms of the current mainstream electric operating devices generally have design shortcomings and are difficult to balance conventional control needs with emergency protection capabilities.

[0003] During circuit switching, if the mechanical switch responds slowly, it is prone to generating a continuous electric arc. This not only accelerates contact wear and shortens the service life of components, but also reduces the safety of circuit control. In addition, some mechanisms with manual emergency functions need to overcome the resistance of complex transmission links, which is laborious and slow to respond. Even if some mechanisms are equipped with spring components, they are mostly only compatible with a single control mode and fail to give full play to their energy storage and release advantages to achieve dual-mode coordinated support, ultimately resulting in poor overall transmission efficiency and control stability.

[0008] In a preferred embodiment of the present invention, a pair of fixed seats are installed inside the circuit breaker housing, and a synchronous shaft is rotatably mounted on the fixed seats.

[0016] Compared with the prior art, the present invention has the following advantages: This invention employs a dual-mode design of mechanical and manual control, with a storage spring providing core support for stable operation in both modes. Under normal operating conditions, mechanical control utilizes the storage and release characteristics of the storage spring, compressing the spring through a transmission structure to store power and then releasing it instantly, achieving automated, high-speed, and stable transmission. This improves circuit switching response efficiency and reduces arc damage, matching conventional control requirements. In case of mechanical control failure, manual control can quickly intervene in an emergency without relying on electric components. The storage spring compresses and stores power synchronously with manual drive, and after passing the critical position, the spring force reverses to assist the rack sliding, reducing operational intensity and ensuring smooth emergency operation. Simultaneously, the storage and release design of the storage spring also ensures rapid mechanical switch action, further reducing the impact of arcs and significantly improving the safety and service life of circuit control.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1: like Figures 1 to 8 As shown, an electric operating device drive transmission mechanism includes a circuit breaker housing 1.

[0022] A mechanical switch 12 is rotatably mounted on the circuit breaker housing 1, and the mechanical switch 12 is interconnected with the circuit inside the circuit breaker. The circuit breaker housing 1 contains a transmission assembly. The transmission assembly includes a slider 242, on which a mechanical control component is mounted; an adjustment cover 23 is rotatably mounted on the side wall of the slider 242, and the adjustment cover 23 is in an inclined state; a push rod 231 is inserted into the adjustment cover 23, and a storage spring 234 is installed between the push rod 231 and the adjustment cover 23; a rack 21 is rotatably mounted at the end of the push rod 231, and a manual control component is mounted on the rack 21; a gear 211 is meshed on the rack 21, and the gear 211 is interconnected with the rotation center of the mechanical switch 12. When the mechanical control component controls the slider 242 to slide, the connection point between the adjusting cover 23 and the slider 242 gradually approaches the connection point between the push rod 231 and the rack 21, and the storage spring 234 is compressed synchronously. When the connection point between the adjusting cover 23 and the slider 242 passes the connection point between the push rod 231 and the rack 21, the storage spring 234 resets and drives the mechanical switch 12 to open and close. When the manual control component moves the rack 21, it directly controls the opening and closing of the mechanical switch 12 without interfering with or affecting the mechanical control component.

[0023] like Figures 1 to 8 As shown in the specific embodiment, an operating cavity 2 is provided inside the circuit breaker housing 1. The transmission assembly, mechanical control assembly, and manual control assembly are all installed inside the operating cavity 2. An inspection door 13 is provided on the side wall of the circuit breaker housing 1, and the inspection door 13 is interconnected with the operating cavity 2. The operating cavity 2 provides independent installation space for each component, which facilitates the layout and assembly of each component. The installation of the inspection door 13 allows personnel to easily inspect and maintain the components inside the operating cavity 2, reducing maintenance difficulty and cost.

[0024] like Figures 1 to 8 As shown, further, a pair of fixed seats 122 are installed inside the circuit breaker housing 1. A synchronous shaft 212 is rotatably mounted on the fixed seats 122. One end of the synchronous shaft 212 is connected to the gear 211, and the other end is connected to the rotation center of the mechanical switch 12. A push plate 121 is installed on the mechanical switch 12, located outside the circuit breaker housing 1. A mark 123 is installed on the circuit breaker housing 1, indicating whether the circuit breaker housing 1 is open or closed, and the mark 123 corresponds to the push plate 121. The fixed seats 122 provide stable mounting support for the synchronous shaft 212, ensuring smooth rotation of the synchronous shaft 212. The synchronous shaft 212 can realize synchronous transmission between the gear 211 and the mechanical switch 12, improving the accuracy of power transmission. The cooperation between the push plate 121 and the mark 123 makes it easy for operators to intuitively judge the open and closed state of the mechanical switch 12, improving the convenience of operation and inspection.

[0025] like Figures 1 to 8 As shown, furthermore, a mounting plate 11 is installed on the side wall of the circuit breaker housing 1. The mounting plate 11 has several pairs of mounting holes 111, which facilitate connection with external structures. The mounting plate 11 and the side wall of the circuit breaker housing 1 are perpendicular to each other, and a reinforcing rib 112, which is triangular, is installed at the connection point. The cooperation between the mounting plate 11 and the mounting holes 111 facilitates quick and precise connection between the mechanism and the external structure, improving installation efficiency. The combination of the vertically arranged mounting plate 11 and the triangular reinforcing rib 112 significantly improves the structural strength of the connection between the mounting plate 11 and the circuit breaker housing 1, enhancing the overall load-bearing capacity and stability of the mechanism.

[0026] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 8As shown, a connecting block 236 is installed at the bottom of the adjusting cover 23, and the connecting block 236 is rotatably connected to the slider 242. A fixing block 235 is installed at the top of the push rod 231, and a connecting plate 232 is rotatably installed at the end of the fixing block 235. The side wall of the connecting plate 232 is welded to the side wall of the rack 21. A baffle 233 is slidably installed inside the adjusting cover 23. One end of the baffle 233 is connected to the end of the push rod 231, and a storage spring 234 is snapped onto the other end of the baffle 233. The other end of the storage spring 234 is snapped onto the side wall of the adjusting cover 23. The storage spring 234 is in a compressed state, and the compression direction of the storage spring 234 and the movement direction of the push rod 231 are both on the same straight line. The connecting block 236 enables the flexible rotational connection between the adjusting cover 23 and the slider 242. The cooperation between the fixing block 235 and the connecting plate 232 enables the top rod 231 and the rack 21 to be stably and rotatably connected, ensuring smooth power transmission. The baffle 233 can effectively limit and support the storage spring 234, ensuring that the compression and reset directions of the storage spring 234 are accurate. The design that the compression direction is consistent with the movement direction of the top rod 231 allows the elastic force of the storage spring 234 to be concentrated on the top rod 231, improving the power transmission efficiency. At the same time, the welded connecting plate 232 enhances the stability of the connection.

[0027] like Figures 1 to 8 As shown, in a specific embodiment, the mechanical control component includes a drive motor 255. A limit seat 253 is mounted on the housing of the drive motor 255. The limit seat 253 is mounted on the circuit breaker housing 1. A worm gear 25 is mounted on the output end of the drive motor 255. A worm wheel 251 is meshed on the bottom of the worm gear 25. The worm wheel 251 is adapted to the countersunk groove 252 opened at the bottom of the circuit breaker housing 1. A positioning shaft 24 is mounted on the rotation center of the worm wheel 251. A lead screw 241 is provided on the positioning shaft 24. The lead screw 241 is meshed with a slider 242. A guide plate 243 is mounted on the side wall of the slider 242. A guide rod 244 is installed through the guide plate 243. The two ends of the guide rod 244 are mounted on the side wall of the circuit breaker housing 1. Mounting seats 245 are rotatably mounted on both ends of the positioning shaft 24. The mounting seats 245 are welded to the side wall of the circuit breaker housing 1. The drive motor 255 provides a stable power source for mechanical control. The limit seat 253 can accurately position and fix the drive motor 255, improving the stability of motor operation. The meshing transmission between the worm gear 25 and the worm wheel 251 has the effect of speed reduction and torque increase, which can improve the stability and torque of power output. The countersunk groove 252 provides installation space for the worm wheel 251, ensuring smooth rotation of the worm wheel 251. The cooperation between the positioning shaft 24 and the mounting seat 245 provides stable support for the lead screw 241. The meshing transmission between the lead screw 241 and the slider 242 can convert rotational motion into linear motion, realizing the precise sliding of the slider 242. The cooperation between the guide plate 243 and the guide rod 244 can accurately limit the sliding trajectory of the slider 242, preventing the slider 242 from deviating and jamming, further improving the stability and accuracy of mechanical control.

[0028] Example 3: The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, the manual control assembly includes a push-pull rod 213. One end of the push-pull rod 213 is connected to the end of the rack 21, and the other end of the push-pull rod 213 is movably inserted through the side wall of the circuit breaker housing 1. A pull ring 214 is installed at the end of the push-pull rod 213. The push-pull rod 213 can directly drive the rack 21 to move, realizing the power transmission for manual control. The movable insertion method ensures smooth operation of the push-pull rod 213. The pull ring 214 increases the contact area for hand operation, making it easier for operators to quickly apply force and improving the convenience of manual operation.

[0029] like Figures 1 to 8 As shown in the specific embodiment, a pair of sliding plates 222 are installed at the bottom of the rack 21. A limiting rod 22 is installed through the sliding plates 222. The two ends of the limiting rod 22 are installed on the side wall of the circuit breaker housing 1. A limiting plate 221 is installed on the limiting rod 22. The limiting plate 221 is used to limit the sliding distance of the rack 21. The cooperation between the sliding plate 222 and the limiting rod 22 can further precisely limit the sliding trajectory of the rack 21, reduce the shaking of the rack 21 during the sliding process, and ensure the effective meshing of the rack 21 and the gear 211. The limiting plate 221 can limit the maximum sliding distance of the rack 21, avoid excessive sliding of the rack 21 which may cause damage to components such as the gear 211 and the synchronous shaft 212, and improve the service life and operational safety of the mechanism.

[0030] The implementation principle of the electric operating device drive transmission mechanism of the present invention is as follows: Under normal operating conditions, mechanical control is preferred: after the drive motor 255 starts, the worm 25 at its output end rotates synchronously, and the worm wheel 251 meshing with the worm 25 rotates in conjunction with it. The worm wheel 251 is fixed coaxially with the positioning shaft 24, and the lead screw 241 on the positioning shaft 24 will rotate synchronously with the worm wheel 251, thereby driving the meshing slider 242 to slide along the axial direction of the lead screw 241. At the same time, the guide plate 243 on the side wall of the slider 242 moves along the trajectory of the guide rod 244, which not only prevents the slider 242 from deviating and jamming, but also makes the power transmission more stable.

[0031] The slider 242 is rotatably connected to the inclined adjustment cover 23 via the connecting block 236. One end of the baffle 233 inside the adjustment cover 23 is fixed to the top rod 231, and the other end is engaged with the energy storage spring 234. The other end of the energy storage spring 234 is fixed to the inner wall of the adjustment cover 23, and its compression direction is completely coincident with the movement direction of the top rod 231, which allows the elastic force to be more concentrated on the top rod 231.

[0032] When slider 242 slides, it drives the adjusting cover 23 to move synchronously. The connection point between adjusting cover 23 and slider 242 gradually approaches the connection point between push rod 231 and rack 21. During this process, push rod 231 retracts into adjusting cover 23, driving baffle 233 to compress storage spring 234. This storage process can accumulate sufficient power to ensure the response speed of subsequent mechanical switch 12 action and reduce the impact of electric arc when the circuit is turned on or off. When the connection point passes the connection point between push rod 231 and rack 21, storage spring 234 releases its elastic force instantly, pushing baffle 233 to drive push rod 231 to move quickly out of adjusting cover 23. The thrust of push rod 231 is transmitted to rack 21 through fixed block 235 and connecting plate 232, causing rack 21 to slide along the trajectory.

[0033] A pair of sliding plates 222 at the bottom of the rack 21 slide against the surface of the limiting rod 22. The limiting plate 221 on the limiting rod 22 not only limits the maximum sliding distance of the rack 21 and prevents damage to the gear 211 or the synchronous shaft 212, but also ensures that the rack 21 is always effectively meshed with the gear 211. The sliding of the rack 21 drives the gear 211 to rotate. The gear 211 is coaxially fixed with the synchronous shaft 212. The synchronous shaft 212 rotates with the gear 211 and drives the mechanical switch 12 to rotate, realizing the rapid switching on and off of the circuit. The push plate 121 on the mechanical switch 12 moves with the rotation of the switch. Its position corresponds to the mark 123 on the housing. The operator can intuitively judge the circuit on and off status through the correspondence between the two.

[0034] Manual control is an emergency backup plan in case of mechanical control failure (such as power failure of drive motor 255, jamming of worm gear 25 and worm wheel 251, obstruction of slider 242, etc.): In this case, the pull ring 214 at the end of the push-pull rod 213 is directly operated. The pull ring 214 is designed to facilitate rapid force application, and the push-pull rod 213 will directly drive the rack 21 to slide along the limit rod 22. During this process, the rack 21 will actively pull the top rod 231 and its connection point to move synchronously. Since the mechanical control components have failed, the connection point between the adjustment cover 23 and the slider 242 is always in a stationary state. As the rack 21 drives the connection point to gradually shift, the relative position relationship between the two continues to change, and the top rod 231 moves telescopically relative to the adjustment cover 23. At this time, the storage spring 234 is compressed synchronously. When the rack 21 drives the connection point between the top rod 231 and itself to pass the stationary connection point between the adjustment cover 23 and the slider 242, the elastic force of the storage spring 234 will push the top rod 231 in the opposite direction, thereby assisting the rack 21 to continue sliding. Even if there is jamming in the mechanical control components, the manual force will not be obstructed when it is transmitted to the adjustment cover 23 through the rack 21 and push rod 231. Ultimately, the rack 21 can still drive the gear 211 to rotate stably. The gear 211 drives the mechanical switch 12 through the synchronous shaft 212 to complete the circuit switching, ensuring that the circuit can still be reliably controlled in case of emergency failure and avoiding the expansion of the fault.

[0035] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
