Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical control technology, specifically to a mechanical fast-response control mechanism for a dynamic thyristor switch. Background Technology
[0002] In the field of electrical control, dynamic thyristor switches are widely used in key scenarios such as power electronics and industrial control due to their characteristics such as high-frequency switching and strong voltage resistance. The response speed and power transmission efficiency of their control mechanism directly determine the working performance of the switch.
[0003] However, existing mechanical control mechanisms for dynamic thyristor switches generally suffer from power transmission lag: traditional control mechanisms often use hinged or bolted connections between drive and transmission components, which easily create gaps at the connection points, resulting in significant power transmission delays. Simultaneously, the large sliding friction between the transmission components and the guide structure further reduces transmission smoothness. This makes it difficult for traditional mechanisms to achieve millisecond-level rapid triggering, failing to meet the high-frequency switching requirements of dynamic thyristors and severely limiting their application range in high-frequency conditions.
[0004] Furthermore, existing mechanical control mechanisms lack a comprehensive coordinated control and buffer protection system, resulting in extremely poor operational stability and control precision. Most mechanisms lack effective buffer structures, making rigid impacts on transmission components prone to collision damage. Additionally, the trigger stroke is difficult to control precisely, easily leading to overtravel issues. The drive, transmission, and triggering processes lack synchronous linkage design, resulting in poor coordination among components. Simultaneously, the lack of a full-process closed-loop control mechanism prevents real-time monitoring and adjustment of component operating status, leading to low triggering accuracy. Moreover, the separation of protection and load-bearing structures in some mechanisms makes internal components susceptible to external environmental interference, further exacerbating operational instability. This results in traditional mechanisms generally suffering from short service life and frequent failures, making it difficult to meet the demands for high-precision and high-stability control. Summary of the Invention
[0005] The purpose of this invention is to address the problems of existing dynamic thyristor switches' mechanical control mechanisms, such as lag in power transmission, difficulty in adapting to high-frequency operating conditions, lack of a complete collaborative regulation and buffer protection system, poor operational stability and control accuracy, and short service life. This invention provides a mechanical fast-response control mechanism for dynamic thyristor switches.
[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A mechanical fast-response control mechanism for a dynamic thyristor switch includes a protective sealing assembly. A drive channel is located at the left end of the protective sealing assembly. A slide rail assembly is located at the bottom inner end of the protective sealing assembly. A transmission assembly is slidably mounted at the top left end of the slide rail assembly. A drive mechanism is movably mounted at the top of the transmission assembly. A buffer mechanism is slidably connected to the top right end of the slide rail assembly. An actuating component is located on the inner side of the top of the buffer mechanism. A trigger head is located between the transmission assembly and the buffer mechanism. An iron core is located at the right end of the slide rail assembly. A controller is located at the bottom inner front end of the protective sealing assembly.
[0007] Furthermore, the protective sealing assembly includes a protective component and a valve. The valve is located on the front side of the protective component, the drive channel is located on the top left end of the protective component, the slide rail assembly extends laterally through both side walls of the protective component, and the drive mechanism extends through the side walls of the protective component and the drive channel. The core components of the overall mechanism are all housed inside the protective component of the protective sealing assembly, and the outer shell of the protective component provides overall protection for all internal structures.
[0008] Furthermore, the protective component includes a housing, heat dissipation holes, and a base. The slide rail assembly and the transmission assembly are located on the top side of the base, and the controller is located on the front side of the base. The housing of the protective component provides overall protection for all internal structures. The heat dissipation holes on the rear side can dissipate the heat generated by the operation of the mechanism in real time. The base provides stable load-bearing support for all components.
[0009] Furthermore, the heat dissipation holes are located on the rear side of the housing, and the base is located at the bottom of the housing. The heat dissipation holes can dissipate the heat generated by the operation of the mechanism in real time, and the base provides stable load-bearing support for all components.
[0010] Furthermore, the slide rail assembly includes a slide block and a slide rail. The bottom side of the slide rail is fixedly connected to the top side of the iron core. The inner side of the slide block is sleeved on the outer right end of the slide rail. The inner side of the bottom end of the transmission component is sleeved on and slides on the outer left end of the slide rail. The slide rail of the slide rail assembly provides precise guidance for all sliding components, eliminating the trigger failure problem caused by component slippage and offset.
[0011] Furthermore, the transmission assembly includes a moving block, an actuating block, and a slot. The bottom side of the moving block is slidably connected to the top side of the iron core. The inner side of the moving block is sleeved and slidably attached to the outer side of the left end of the slide rail assembly. The bottom end of the driving mechanism passes through and is rotatably connected to the inner side of the top end of the slot. The bottom left end of the actuating assembly is fixedly connected to the upper right side of the slot. The magnetic attraction force of the iron core can assist the moving block to quickly return to its original position, further improving the reset response speed.
[0012] Furthermore, the bottom end of the execution block is located on the top side of the moving block, and the bottom end of the slot is embedded in the top end of the execution block. The moving block synchronously drives the execution block and the slot at the top to slide horizontally along the slide rail, thereby achieving precise power transmission and directional drive.
[0013] Furthermore, the drive mechanism includes a rotating shaft, an embedded component, and an operating lever. The left end of the actuating component is elastically connected to the right side of the bottom end of the drive mechanism. The rotating shaft is rotatably connected to the top end of the transmission component. The bottom end of the embedded component is fixedly connected to the top side of the rotating shaft. The outer side of the bottom end of the operating lever is connected through to the inside of the top end of the embedded component. The rotating shaft synchronously drives the embedded component at the bottom end to move downward. The sensing plate at the bottom end of the actuating column of the embedded component is pressed down and precisely engaged with the slot inside the top end of the transmission component, forming a rigid linkage between the drive mechanism and the transmission component, thus completing the power connection.
[0014] Furthermore, the embedded component includes an actuating column, a sensing plate, and a slot. The sensing plate is located at the bottom left side of the actuating column, and the slot is located at the top left side of the transmission component. The sensing plate is movably engaged with the inside of the slot. When the controller issues a command to disconnect the thyristor switch, the operating lever of the drive mechanism is reversed and reset, causing the rotating shaft and the embedded component to move upward.
[0015] Furthermore, the buffer mechanism includes a slider, a sliding assembly, and a buffer spring. Two sets of sliders are provided. The bottom end of the slider is sleeved and slidably connected to the outer right end of the top of the slide rail assembly. The right end of the actuating assembly is fixedly connected to the left end of the inner shaft of the buffer spring. The right end of the iron core is fixedly connected to the left side of the sliding assembly at the left end. Furthermore, the bottom end of the sliding component is fixedly connected to the top side of the slider, and the inner sides of the top ends of the two sets of sliding components are respectively set at both ends of the buffer spring. The pushing force of the push rod is transmitted to the support of the sliding component, pushing the two sets of sliding components to move towards each other along the slide. The telescopic frame of the sliding component contracts synchronously, causing the inner buffer spring to be compressed.
[0016] Furthermore, the sliding assembly includes a first bracket, a telescopic frame, and a second bracket. The first bracket and the second bracket are respectively disposed at the top of the left and right ends of the buffer spring. The elastic rebound force of the buffer spring can effectively offset the rigid impact of the transmission assembly and avoid damage to the components caused by the hard collision between the transmission assembly and the buffer mechanism.
[0017] Furthermore, the triggering component includes a push rod and an electric cylinder. The bottom left end of the push rod is fixedly connected to the top right side of the transmission component, and the top left end of the push rod is movably connected to the bottom right side of the drive mechanism. The outer side of the right end of the push rod passes through and slides into the interior of the left end of the electric cylinder. The reset thrust of the buffer mechanism is synchronously transmitted to the push rod of the triggering component, pushing the push rod to slide to the left to reset.
[0018] Compared with the prior art, the present invention provides a mechanical fast-response control mechanism for a dynamic thyristor switch, which has the following advantages: 1. The mechanical fast-response control mechanism of this dynamic thyristor switch significantly improves the response speed and power transmission efficiency of the thyristor switch control through the embedded rigid linkage design between the drive mechanism and the transmission component. In the embedded component of the drive mechanism, the induction plate and the slot of the transmission component are movably engaged to form a rigid linkage structure, enabling lag-free transmission of driving power and effectively avoiding the gaps and lags in power transmission found in traditional control mechanisms. Simultaneously, the iron core at the right end of the slide rail component provides magnetic assistance, reducing sliding friction between the transmission component and the slide rail, further improving transmission smoothness. Through the synergistic design of "rigid linkage + magnetic assistance," the mechanism can achieve millisecond-level rapid power transmission and triggering action, precisely matching the high-frequency switching requirements of the dynamic thyristor, and solving the problems of lag and inability to adapt to high-frequency operating conditions in traditional mechanical control mechanisms.
[0019] 2. The mechanical fast-response control mechanism of this dynamic thyristor switch significantly improves operational stability and control accuracy through a closed-loop control system encompassing the entire process of "drive-transmission-touch-buffering-triggering-reset". The buffer mechanism forms an elastic buffer linkage structure with the telescopic frame of two sets of sliding components and the buffer spring, effectively offsetting the rigid impact of the transmission components and preventing component collision damage, while precisely controlling the trigger stroke to prevent overtravel. The left end of the touch component is elastically connected to the transmission component and drive mechanism, while the right end is coaxially fixed to the buffer spring, achieving synchronous linkage between transmission and buffering. The controller is signal-connected to the touch component and embedded component, enabling it to receive action signals in real time and regulate the operation of each component, forming a closed-loop control. In addition, the protective sealing component integrates protection and load-bearing functions, providing a stable operating environment for the internal components. The overall structure achieves synergy between fast response and stable protection, solving the problems of easy deviation, low triggering accuracy, and short service life of traditional mechanisms.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:
[0023] like Figures 1-3As shown, a mechanical fast-response control mechanism for a dynamic thyristor switch includes a protective sealing assembly 1. The protective sealing assembly 1 includes a protective component 11 and a valve 12. The valve 12 is located on the front side of the protective component 11. The protective component 11 includes a housing 111, a heat dissipation hole 112, and a base 113. The heat dissipation hole 112 is located on the rear side of the housing 111, and the base 113 is located at the bottom of the housing 111. The housing 111 of the protective component 11 provides overall protection for all internal structures. The heat dissipation hole 112 on the rear side can dissipate the heat generated by the operation of the mechanism in real time. The base 113 provides stable load-bearing support for all components. The valve 12 on the front side can open and close the front opening of the protective component 11.
[0024] like Figure 7 As shown, a drive channel 2 is provided at the left end of the protective sealing component 1. The drive channel 2 is located at the top left end of the protective component 11. A slide rail component 3 is provided at the bottom inner side of the protective sealing component 1. The slide rail component 3 extends laterally through both side walls of the protective component 11. The slide rail component 3 includes a slide seat 31 and a slide rail 32. The inner side of the slide seat 31 is fitted onto the outer right end of the slide rail 32. The slide rail 32 of the slide rail component 3 provides precise guidance for all sliding parts, preventing trigger failure caused by component slippage.
[0025] A transmission component 4 is slidably disposed on the top left end of the slide rail assembly 3. The slide rail assembly 3 and the transmission component 4 are disposed on the top side of the base 113. The bottom inner side of the transmission component 4 is sleeved and slides on the outer left end of the slide rail 32. The transmission component 4 includes a moving block 41, an execution block 42 and a slot 43. The inner side of the moving block 41 is sleeved and slides on the left outer side of the slide rail assembly 3. The bottom end of the drive mechanism 5 passes through and is rotatably connected to the top inner side of the slot 43. The bottom end of the execution block 42 is disposed on the top side of the moving block 41. The bottom end of the slot 43 is embedded in the top end of the execution block 42. The operator can drive the rotating shaft 51 to rotate on the top inner side of the slot 43 of the transmission component 4 by operating the operating rod 53 of the drive mechanism 5. The rotating shaft 51 synchronously drives the bottom embedded component 52 to move downward.
[0026] like Figures 7-9As shown, a drive mechanism 5 is movably mounted on the top of the transmission assembly 4. The drive mechanism 5 penetrates the side walls of the protective assembly 11 and the drive channel 2. The drive mechanism 5 includes a rotating shaft 51, an embedded component 52, and an operating rod 53. The rotating shaft 51 is rotatably connected to the top of the transmission assembly 4. The bottom end of the embedded component 52 is fixedly connected to the top side of the rotating shaft 51. The outer side of the bottom end of the operating rod 53 is connected through to the inside of the top of the embedded component 52. The embedded component 52 includes an actuating column 521, a sensing plate 522, and a slot 523. The sensing plate 522 is located at the bottom left side of the actuating column 521, and the slot 523 is located at the top left side of the transmission assembly 4. The sensing plate 522 is movably engaged with the inside of the slot 523. The rotating shaft 51 synchronously drives the embedded component 52 at the bottom to move downward. The sensing plate 522 at the bottom of the actuating column 521 of the embedded component 52 is pressed down and precisely engaged with the inside of the slot 523 at the top of the transmission assembly 4, forming a rigid linkage between the drive mechanism 5 and the transmission assembly 4, thus completing the power connection. Example 2:
[0027] like Figures 4-6 As shown, a buffer mechanism 6 is slidably connected to the top right end of the slide rail assembly 3. The buffer mechanism 6 includes a slider 61, a sliding component 62, and a buffer spring 63. Two sets of sliders 61 are provided. The bottom end of the slider 61 is sleeved and slidably connected to the outer right end of the top of the slide rail assembly 3. The bottom end of the sliding component 62 is fixedly connected to the top side of the slider 61. The inner sides of the tops of the two sets of sliding components 62 are respectively located at both ends of the buffer spring 63. The sliding component 62 includes a first bracket 621, a telescopic bracket 622, and a second bracket 623. The first bracket 621 and the second bracket 623 are respectively located at the top of the left and right ends of the buffer spring 63. As the transmission component 4 continues to move to the right, the right end of the push rod 71 of the trigger component 7 first contacts the left end of the buffer mechanism 6. The pushing force of the push rod 71 is transmitted to the bracket 621 of the sliding component 62, pushing the two sets of sliding components 62 to move towards each other along the slide 32. The telescopic frame 622 of the sliding component 62 contracts synchronously, causing the inner buffer spring 63 to be compressed. The elastic rebound force of the buffer spring 63 can effectively offset the rigid impact of the transmission component 4, avoiding hard collision between the transmission component 4 and the buffer mechanism 6 and causing damage to the components. At the same time, the elastic buffering effect of the buffer mechanism 6 can accurately control the sliding stroke of the transmission component 4 and prevent over-travel displacement.
[0028] like Figure 7 and Figure 9As shown, an actuating component 7 is provided on the inner side of the top of the buffer mechanism 6. The right end of the actuating component 7 is fixedly connected to the left end of the inner shaft of the buffer spring 63. The bottom of the left end of the actuating component 7 is fixedly connected to the upper right end of the slot 43. The left end of the actuating component 7 is elastically connected to the right side of the bottom end of the drive mechanism 5. The actuating component 7 includes a push rod 71 and an electric cylinder 72. The bottom of the left end of the push rod 71 is fixedly connected to the top right end of the transmission component 4. The top of the left end of the push rod 71 is movably connected to the bottom right end of the drive mechanism 5. The outer side of the right end of the push rod 71 passes through and slides to the inside of the left end of the electric cylinder 72. The reset thrust of the buffer mechanism 6 is synchronously transmitted to the push rod 71 of the actuating component 7, pushing the push rod 71 to slide to the left to reset. The push rod 71 drives the moving block 41 of the transmission component 4 to slide to the left along the slide 32 to the initial position.
[0029] like Figures 1-9 As shown, a trigger head 8 is provided between the transmission component 4 and the buffer mechanism 6. An iron core 9 is provided at the right end of the slide rail component 3. The bottom side of the slide rail 32 is fixedly connected to the top side of the iron core 9. The bottom side of the moving block 41 is slidably connected to the top side of the iron core 9. The right end of the iron core 9 is fixedly connected to the left side of the sliding component 62 at the left end. A controller 10 is provided at the bottom of the inner front end of the protective sealing component 1. The controller 10 is located at the front side of the base 113. The magnetic attraction force of the iron core 9 can reduce the sliding friction of the moving block 41 and improve the smoothness and response speed of the transmission.
[0030] Working principle: such as Figures 1-9 As shown, in the initial state of the equipment, the core components of the overall mechanism are all housed inside the protective component 11 of the protective sealing component 1. The outer shell 111 of the protective component 11 provides overall protection for all internal structures. The heat dissipation holes 112 on the rear side can dissipate the heat generated by the operation of the mechanism in real time. The base 113 provides stable load-bearing support for all components. The valve 12 on the front side can open and close the front opening of the protective component 11, which not only ensures that the internal structure is dustproof and dirtproof, but also facilitates later inspection and maintenance.
[0031] The controller 10 is fixedly installed on the front side of the base 113. As the core control unit of the entire mechanism, it is electrically connected to each actuator and receives sensing signals to coordinate and regulate the start, stop, and running rhythm of all components. The slide rail 32 of the slide rail assembly 3 runs horizontally through the two side walls of the protective assembly 11 and is fixed to the top side of the base 113, providing a horizontal guide reference for all sliding components. The iron core 9 is fixed to the top right end of the slide rail 32, providing magnetic attraction assistance for the transmission and triggering links to ensure the stability of the transmission.
[0032] The first step, mechanism start-up and drive transmission stage: When the controller 10 issues a thyristor switch trigger command, the operator can drive the rotating shaft 51 to rotate inside the top of the slot 43 of the transmission component 4 by manipulating the operating lever 53 of the drive mechanism 5. The rotating shaft 51 simultaneously drives the bottom embedded component 52 to move downward. The sensing plate 522 at the bottom of the actuator column 521 of the embedded component 52 is pressed down and precisely engaged with the slot 523 at the top of the transmission component 4, forming a rigid linkage between the drive mechanism 5 and the transmission component 4, and completing the power connection.
[0033] After the power of the drive mechanism 5 is transmitted to the transmission component 4 through the rotating shaft 51 and the embedded component 52, the moving block 41 of the transmission component 4 is driven to slide to the left along the slide rail 32 of the slide rail component 3. The bottom end of the moving block 41 slides against the top side of the iron core 9. The magnetic attraction force of the iron core 9 can reduce the sliding friction of the moving block 41 and improve the smoothness and response speed of the transmission.
[0034] The moving block 41 synchronously drives the top execution block 42 and the slot 43 to slide horizontally along the slide rail 32, realizing precise power transmission and directional drive.
[0035] The second step is the triggering and preparation stage: During the horizontal sliding process of the transmission component 4, its right top end will synchronously drive the push rod 71 of the trigger component 7 to move horizontally to the right. The top left end of the push rod 71 is always in contact with the bottom right end of the drive mechanism 5, which can synchronously receive the power transmission of the drive mechanism 5 and ensure that the linkage is smooth.
[0036] The outer right end of the push rod 71 is slidably connected to the inner left end of the electric cylinder 72. Under the control of the controller 10, the electric cylinder 72 provides auxiliary thrust for the sliding of the push rod 71, further accelerating the movement speed of the push rod 71, realizing the synchronous linkage between the trigger component 7 and the transmission component 4, and preparing for the subsequent thyristor triggering action.
[0037] The third step, buffer protection and precise triggering stage: When the transmission component 4 slides to the right along the slide 32 to the designated position, it will gradually approach the buffer mechanism 6. At this time, the two sets of sliders 61 of the buffer mechanism 6 are both sleeved on the outer side of the right end of the slide 32. The sliding component 62 on the top side of the slider 61 is in an extended state. The first bracket 621 and the second bracket 623 of the sliding component 62 are respectively supported on both ends of the buffer spring 63. The buffer spring 63 maintains its initial elastic state.
[0038] As the transmission component 4 continues to move to the right, the right end of the push rod 71 of the trigger component 7 first contacts the left end of the buffer mechanism 6. The pushing force of the push rod 71 is transmitted to the bracket 621 of the sliding component 62, pushing the two sets of sliding components 62 to move towards each other along the slide 32. The telescopic frame 622 of the sliding component 62 contracts synchronously, causing the inner buffer spring 63 to be compressed.
[0039] The elastic rebound force of the buffer spring 63 can effectively offset the rigid impact of the transmission component 4, avoiding damage to the components caused by the hard collision between the transmission component 4 and the buffer mechanism 6. At the same time, the elastic buffering effect of the buffer mechanism 6 can accurately control the sliding stroke of the transmission component 4 and prevent over-travel displacement.
[0040] While the buffer mechanism 6 buffers and unloads the force, the right end of the transmission component 4 makes precise contact with the trigger head 8. The trigger head 8 is pushed by the thrust of the transmission component 4, completing the precise mechanical contact with the trigger end of the dynamic thyristor switch, thus achieving rapid conduction of the thyristor switch. This triggering process relies on the rigid cooperation of the mechanical transmission, eliminating the problem of electrical control hysteresis, and achieving a millisecond-level rapid response, meeting the high-frequency switching requirements of dynamic thyristors.
[0041] The fourth step, reset buffer and switch disconnection stage: When the controller 10 issues the thyristor switch disconnection command, the operating lever 53 of the drive mechanism 5 is reversed and reset, driving the rotating shaft 51 and the embedded component 52 to move upward, and the sensing plate 522 disengages from the inside of the slot 523, thus releasing the linkage between the drive mechanism 5 and the transmission component 4.
[0042] At this time, the compressed buffer spring 63 releases its elastic potential energy, and the elastic rebound force pushes the telescopic frame 622 of the sliding component 62 to extend, causing the two sets of sliders 61 to slide back to their original positions along the slide rail 32. The reset thrust of the buffer mechanism 6 is synchronously transmitted to the push rod 71 of the trigger component 7, pushing the push rod 71 to slide back to the left. The push rod 71 drives the moving block 41 of the transmission component 4 to slide back to its initial position along the slide rail 32. During the reset process of the transmission component 4, the trigger head 8 disengages from the trigger end of the thyristor switch, achieving stable disconnection of the thyristor switch.
[0043] The magnetic attraction force of the iron core 9 can assist the moving block 41 to return to its position quickly, further improving the response speed of the reset. Throughout the reset process, the elastic buffer of the buffer spring 63 is always present, avoiding structural displacement or component wear caused by the inertial impact of the transmission component 4 during reset, thus ensuring the stability of the mechanism operation.
[0044] The fifth step, closed-loop control and continuous protection stage: During the operation of the entire mechanism, the controller 10 receives position and action signals from the sensing plate 522 of the embedded component 52 and the electric cylinder 72 of the trigger component 7 in real time, and precisely controls the start and stop of the drive mechanism 5, the thrust of the trigger component 7 and the buffer stroke of the buffer mechanism 6, forming a closed-loop control of trigger-conduction-disconnection-reset. The triggering force and on / off rhythm can be flexibly adjusted according to the working requirements of the thyristor.
[0045] The outer shell 111 of the protective sealing assembly 1 always protects the internal structure, and the heat dissipation holes 112 continuously dissipate heat, preventing the mechanism from affecting its operational accuracy due to high temperatures. The slide rail 32 of the slide rail assembly 3 provides precise guidance for all sliding parts, eliminating trigger failure problems caused by component slippage and displacement.
