Description

Technical Field

[0001] This application relates to the field of mechanical equipment drive and control, and in particular to a multi-turn output three-station device with anti-reverse operation function. Background Technology

[0002] In power systems, three-position switches play a crucial role in controlling the opening and closing operations of disconnecting switches and grounding switches. Reliable three-position switches can ensure the stable operation of the power system, reduce the probability of faults, and improve the safety and stability of power supply.

[0003] In related technologies, to drive and control three-station equipment, a motor-driven output shaft is typically used to operate the disconnecting and grounding switches. For manual operation, a hand crank is usually directly connected to the drive unit, and a worm gear transmission structure is typically used to increase the output torque. When the equipment reaches the open, disconnecting, or grounding closing positions, although mechanical limit structures are provided to restrict further movement, the actual torque acting on the limit points is significantly amplified due to the large transmission ratio of the worm gear.

[0004] Regarding the aforementioned technologies, the inventors believe that the three-station equipment lacks an effective anti-reverse operation function. When the hand crank is not rotated to the correct position, i.e., when the isolating switch or grounding switch is not fully opened or closed, the hand crank is prone to detaching directly from the drive hole, posing a safety hazard to the circuit. When the hand crank is over-rotated, i.e., when the isolating switch or grounding switch has been opened or closed but the hand crank is still rotated, its mechanical limit structure is at risk of insufficient structural strength when actually bearing torque due to the amplification effect of the transmission ratio. Summary of the Invention

[0005] To reduce the risk of the hand crank dislodging directly from the drive hole when it is not fully rotated and the risk of equipment damage due to the amplification of the transmission ratio when the hand crank is over-rotated, this application provides a multi-turn output three-station device with anti-reverse operation function.

[0006] The multi-turn output three-station device with anti-reverse operation function provided in this application adopts the following technical solution: A multi-turn output three-station device with anti-reverse operation function includes a frame body, an output mechanism arranged on the frame body, a drive motor for driving the output mechanism, and an unlocking mechanism for unlocking the output mechanism. The output mechanism includes an output main shaft arranged horizontally on the frame body, an output secondary shaft arranged perpendicular to the output main shaft and used to control the opening and closing of a disconnecting switch and a grounding switch, an output linkage assembly for linking the output main shaft and the output secondary shaft, an isolation drive assembly arranged on the frame body and driving the output linkage assembly to rotate, and an output linkage assembly arranged on the frame body and driving the output linkage assembly. The device includes a grounding drive assembly for rotating components; the output shaft of the drive motor is connected to the output linkage assembly; the frame body has a mounting bracket for arranging the isolation drive assembly and the grounding drive assembly; it also includes a hand crank for driving the isolation drive assembly and the grounding drive assembly to rotate, the end of the hand crank having a connecting post, the isolation drive assembly having a first drive hole for arranging the connecting post, and the grounding drive assembly having a second drive hole for arranging the connecting post; the mounting bracket is provided with an anti-reverse operation mechanism for preventing the hand crank from disengaging from the first drive hole or the second drive hole.

[0007] By adopting the above technical solution, the equipment can operate the output mechanism through a drive motor or hand crank, thereby controlling the opening and closing of the disconnecting switch and the grounding switch. When the opening and closing operation is achieved through the drive motor, the operator starts the drive motor, and the output shaft of the drive motor drives the output linkage component to rotate. The output linkage component drives the output sub-shaft to rotate, thereby realizing the opening and closing operation of the disconnecting switch and the grounding switch. When performing manual opening and closing operation, the operator can drive the disconnecting drive component or the grounding drive component to rotate by rotating the hand crank. Both the disconnecting drive component and the grounding drive component can independently drive the output main shaft to rotate, and drive the output sub-shaft to rotate through the output linkage component, thereby realizing the opening and closing operation of the disconnecting switch and the grounding switch. The anti-reverse operation mechanism ensures that the connecting pin is not easily dislodged from the first drive hole or the second drive hole when the hand crank is not rotated to the correct position, thereby ensuring the safety and stability of the equipment operation.

[0008] Optionally, the isolation drive assembly includes an isolation drive shaft vertically arranged at the bottom of the mounting bracket and an isolation drive gear arranged on the isolation drive shaft; the grounding drive assembly includes a grounding drive shaft vertically arranged at the bottom of the mounting bracket and a grounding drive gear arranged on the grounding drive shaft and meshing with the isolation drive gear; the output linkage assembly has an input gear meshing with the grounding drive gear; the mounting bracket has a first arrangement hole for arranging the end of the isolation drive shaft and a second arrangement hole for arranging the end of the grounding drive shaft.

[0009] By adopting the above technical solution, the isolation drive shaft and the ground drive shaft are vertically arranged at the bottom of the mounting bracket. With the meshing of the isolation drive gear and the ground drive gear, as well as the meshing of the input gear and the ground drive gear, the power can be effectively transmitted, enabling the output linkage component to operate normally. The first arrangement hole and the second arrangement hole provide arrangement space for the ends of the isolation drive shaft and the ground drive shaft, ensuring the stable installation of each component, thereby ensuring that the equipment can stably control the opening and closing of the isolation switch and the ground switch.

[0010] Optionally, the anti-reverse operation mechanism includes a first sliding plate that slides horizontally and locks the hand crank, and a first drive plate that drives the first sliding plate to slide horizontally; the first sliding plate has a first limiting groove for locking the hand crank in the first arrangement hole and a second limiting groove for locking the hand crank in the second arrangement hole; the hand crank is provided with a limiting ring groove on the side near the connecting post, the first sliding plate is provided with a first limiting plate that cooperates with the limiting ring groove on one side of the first limiting groove, and the first sliding plate is provided with a second limiting plate that cooperates with the limiting ring groove on one side of the second limiting groove; the first drive plate is connected to the side of the first sliding plate and extends downward, the lower end of the first drive plate has a first rack extending in the horizontal direction, and the output spindle is provided with a first drive gear that meshes with the first rack opposite the first drive plate.

[0011] By adopting the above technical solution, the operator can rotate the hand crank to drive the output spindle to rotate. The first drive plate meshes with the first drive gear of the output spindle through the first rack, which can drive the first sliding plate to slide horizontally according to the rotation of the output spindle. The first sliding plate can lock the hand crank in the first arrangement hole and the second arrangement hole through the first limiting groove and the second limiting groove respectively. When the hand crank is not rotated to the position, the first limiting plate or the second limiting plate is always locked in the limiting ring groove of the hand crank, which further enhances the locking effect and reduces the risk of the hand crank coming off when it is not rotated to the position.

[0012] Optionally, the hand crank is provided with a spline structure between the limiting ring groove and the connecting post; the first sliding plate is provided with first locking blocks at both ends of the first limiting groove, and the first locking blocks are provided with first locking teeth that cooperate with the spline structure on the side facing the first limiting groove; the first sliding plate is provided with second locking blocks at both ends of the second limiting groove, and the second locking blocks are provided with second locking teeth that cooperate with the spline structure on the side facing the second limiting groove.

[0013] By adopting the above technical solution, the spline structure on the hand crank cooperates with the first locking tooth of the first locking block and the second locking tooth of the second locking block on the first sliding plate, which can further enhance the connection stability and reliability between the hand crank and the first sliding plate, so that the hand crank is more firmly locked in the first or second limiting groove. When the disengagement, isolation, and grounding are in place, the locking teeth enter the spline structure to restrict further movement. Without the worm gear ratio change, the resisting force is equivalent to the input force and is within the bearing range of the anti-reverse operation mechanism. This reduces the risk of deformation of the anti-reverse operation mechanism or damage to the switching equipment due to misoperation caused by over-rotation of the hand crank, and improves the safety of the three-station equipment.

[0014] Optionally, the top of the mounting bracket is provided with a first guide block, and the first sliding plate is provided with a first sliding groove that cooperates with the first guide block along the sliding direction; the frame body is provided with a second guide block on the side facing the first drive plate, and the first drive plate is provided with a second sliding groove that cooperates with the second guide block along the sliding direction.

[0015] By adopting the above technical solution, the first guide block cooperates with the first slide groove, and the second guide block cooperates with the second slide groove, which can provide guidance for the horizontal sliding of the first sliding plate and the first drive plate, respectively, ensuring the stability and accuracy of the first sliding plate and the first drive plate during the sliding process, thereby ensuring the stable and reliable locking function of the anti-reverse operation mechanism for the hand joystick.

[0016] Optionally, the frame body has an operation panel above the mounting bracket. The operation panel has a first operation hole and a second operation hole that are directly opposite to the first drive hole and the second drive hole, respectively. The operation panel is provided with a baffle assembly for covering the first operation hole and the second operation hole. The baffle assembly includes a baffle body slidably arranged on the bottom side of the operation panel and an operating member arranged on the top of the baffle body and driving the baffle body to slide. The baffle body has a first clearance hole corresponding to the first operation hole and a second clearance hole corresponding to the second operation hole. The operation panel has a sliding groove for the operating member to slide. The sliding groove includes a first groove, a second groove connected to one side of the first groove and corresponding to the first operation hole, and a second groove connected to the other side of the first groove and corresponding to the second operation hole.

[0017] By adopting the above technical solution, when the operating component is in the first slot, the operator can start the drive motor to drive the output mechanism to open and close the disconnect switch and the grounding switch; when the operator manually adjusts the operating component to slide it to the second slot, the first clearance hole is aligned with the first drive hole, the first operating hole is in the open state and the second operating hole is in the closed state, the operator can place the connecting pin of the hand crank in the first drive hole, and open and close the disconnect switch by rotating the hand crank; when the operator manually adjusts the operating component to slide it to the third slot, the second clearance hole is aligned with the second drive hole, the first operating hole is in the closed state and the second operating hole is in the open state, the operator can place the connecting pin of the hand crank in the second drive hole, and open and close the grounding switch by rotating the hand crank.

[0018] Optionally, an auxiliary switching mechanism is also included; the auxiliary switching mechanism includes an isolation auxiliary switch, an isolation display element rotatably arranged on top of the isolation auxiliary switch, a grounding auxiliary switch, a grounding display element rotatably arranged on top of the grounding auxiliary switch, and an auxiliary drive assembly for driving the isolation display element and the grounding display element to rotate; the frame body has a support base for arranging the isolation auxiliary switch and the grounding auxiliary switch; the isolation display element has an isolation display plate rotatably arranged; the grounding display element has a grounding display plate rotatably arranged; the auxiliary drive assembly includes an isolation drive block for driving the isolation display plate to rotate, a grounding drive block for driving the grounding display plate to rotate, and an auxiliary drive plate for driving the isolation drive block and the grounding drive block to rotate; the auxiliary drive plate has a second rack extending in a horizontal direction, and the output spindle is provided with a second drive gear meshing with the second rack.

[0019] By adopting the above technical solution, the auxiliary switch mechanism enables operators to monitor and display the equipment's operating status during manual opening and closing. When the operator rotates the hand crank to drive the isolation drive assembly, the isolation display panel switches between "open" and "closed" under the synchronous drive of the auxiliary drive assembly, thus assisting the operator in determining whether the isolation switch is in the open / closed state. When the operator rotates the hand crank to drive the grounding drive assembly, the grounding display panel switches between "open" and "closed" under the synchronous drive of the auxiliary drive assembly, thus assisting the operator in determining whether the grounding switch is in the open / closed state. The auxiliary drive assembly utilizes the second rack of the auxiliary drive plate to mesh with the second drive gear of the output spindle, transmitting the rotation of the output spindle to the isolation drive block and the grounding drive block, thereby driving the isolation display panel and the grounding display panel to rotate, achieving the status display function.

[0020] Optionally, the auxiliary drive plate has a third sliding groove extending along the sliding direction, and the frame body has a third slider that cooperates with the third sliding groove; the isolation drive block has an isolation groove structure, the isolation groove structure including a first sliding groove and a first rotating groove connected to the first sliding groove, and the auxiliary drive plate has a first limiting post that cooperates with the isolation groove structure; the grounding drive block has a grounding groove structure, the grounding groove structure including a second sliding groove and a second rotating groove connected to the second sliding groove, and the auxiliary drive plate has a second limiting post that cooperates with the grounding groove structure.

[0021] By adopting the above technical solution, the third slide groove and the third slider can guide and limit the sliding of the auxiliary drive board, ensuring its sliding stability; the isolation groove structure cooperates with the first limiting post, and the grounding groove structure cooperates with the second limiting post, enabling the auxiliary drive board to accurately drive the isolation drive block and the grounding drive block to rotate, realizing precise control of the rotation of the isolation display board and the grounding display board, thereby making the working status display of the isolation auxiliary switch and the grounding auxiliary switch more accurate.

[0022] Optionally, the unlocking mechanism includes a locking plate vertically sliding on the main body of the frame, an unlocking component connected to the top of the locking plate and driving the locking plate to move downward, and a first spring arranged at the bottom of the locking plate and driving the locking plate to reset; the output spindle is provided with a rotating locking disk, the outer edge of the rotating locking disk is provided with a plurality of locking slots arranged at intervals, and the locking plate is provided with a first locking post on the side facing the output spindle, which cooperates with and limits the locking slots; the isolation drive shaft is provided with a locking gear, and the locking plate is provided with a second locking post on the side facing the isolation drive shaft for the locking gear to engage.

[0023] By adopting the above technical solution, before the operator manually opens and closes the circuit breaker, he / she needs to press down the unlocking component to drive the locking plate to move downward, thereby unlocking the output main shaft and the isolation drive shaft. The first spring can reset the locking plate. The locking groove of the rotating locking disc cooperates with the first locking pin, and the locking gear cooperates with the second locking pin, thereby locking the output main shaft and the isolation drive shaft, which helps to ensure the safe and stable operation of the equipment.

[0024] Optionally, a contact structure is provided between the locking mechanism and the output spindle to restrict the vertical movement of the locking mechanism; the contact structure includes a contact post arranged on the side of the locking plate facing the output spindle, and a contact plate arranged on the output spindle for the end of the contact post to contact; the end of the contact post is provided with a mounting hole and a ball spring plunger is provided in the mounting hole, and the contact plate is provided with a plurality of snap-fit ​​holes on the side facing the contact post for the plunger ball of the ball spring plunger to snap-fit.

[0025] By adopting the above technical solution, an abutment structure is set between the locking mechanism and the output spindle. The ball head of the ball spring plunger at the end of the abutment column engages with the locking hole on the abutment plate, which can effectively limit the up and down movement of the locking mechanism and improve the stability of the equipment operation.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A multi-turn output three-position device with anti-reverse operation function, comprising a frame body, an output mechanism, a drive motor, and an unlocking mechanism; the device can control the opening and closing of the disconnecting switch and the grounding switch by operating the output mechanism through the drive motor or a hand crank; when the opening and closing operation is achieved by the drive motor, the operator starts the drive motor, the output shaft of the drive motor drives the output linkage component to rotate, and the output linkage component drives the output sub-shaft to rotate, thereby realizing the opening and closing operation of the disconnecting switch and the grounding switch; when performing manual opening and closing operation, the operator can drive the disconnecting drive component or the grounding drive component to rotate by rotating the hand crank, and both the disconnecting drive component and the grounding drive component can independently drive the output main shaft to rotate, and drive the output sub-shaft to rotate through the output linkage component, thereby realizing the opening and closing operation of the disconnecting switch and the grounding switch; the anti-reverse operation mechanism makes it difficult for the connecting pin to disengage from the first drive hole or the second drive hole when the hand crank is not rotated to the correct position, thereby ensuring the safety and stability of the device operation; 2.

[0059] The implementation principle of a multi-turn output three-station device with anti-reverse operation function in this application embodiment is as follows: The device can realize the operation of the output mechanism 2 through the drive motor 3 or the hand crank 6, thereby controlling the opening and closing of the disconnecting switch and the grounding switch; When the opening and closing operation is realized by the drive motor 3, the operator starts the drive motor 3, the output shaft of the drive motor 3 drives the output linkage component 23 to rotate, the output linkage component 23 drives the output sub-shaft 22 to rotate, thereby realizing the opening and closing operation of the disconnecting switch and the grounding switch; When performing manual opening and closing operation, the operator can drive the disconnecting drive component 24 or the grounding drive component 25 to rotate by rotating the hand crank 6. Both the disconnecting drive component 24 and the grounding drive component 25 can independently drive the output main shaft 21 to rotate, and drive the output sub-shaft 22 to rotate through the output linkage component 23, thereby realizing the opening and closing operation of the disconnecting switch and the grounding switch; The setting of the anti-reverse operation mechanism 7 makes it difficult for the connecting pin 631 to disengage from the first drive hole 2411 or the second drive hole 2511 when the hand crank 6 is not rotated to the correct position, thereby ensuring the safety and stability of the device operation.
