Description

Technical Field

[0001] This invention relates to the field of power system simulation technology, specifically to an excitation system simulation platform. Background Technology

[0002] Power system simulation technology refers to the use of computer simulation methods to model, analyze, and optimize power systems. A power system includes generation, transmission, distribution, and consumption, and the excitation system is a crucial component of the power system.

[0003] The excitation system is primarily used to control the electric field excitation of the generator, enabling it to produce a constant voltage and frequency. Excitation system simulation platforms allow for the modeling and simulation of various parameters to model the generator's response and stability under different operating conditions. These platforms assist power system engineers and researchers in the design, commissioning, and optimization of generator excitation systems. Through these platforms, the impact of the excitation system on the power system can be analyzed, response speed and stability can be evaluated, and fault analysis and strategy development can be performed.

[0004] However, most existing excitation system simulation platforms are integrated structures, and their data interfaces and displays are directly exposed when not in operation, making them susceptible to damage from human or environmental factors such as bumps and dust, which affects the service life and reliability of the equipment. Summary of the Invention

The invention provides an excitation system simulation platform that provides physical protection for its data interface and display screen when not in operation.

[0007] As a preferred embodiment, the flipping assembly further includes a first bushing and a rotating shaft. A plurality of first bushings are fixed to both sides of the support platform, and the rotating shaft is rotatably connected to the inner side of the first bushings and fixedly connected to the flipping platform.

[0009] As a preferred embodiment, the top support assembly further includes a rectangular platform fixedly connected to both sides of the support platform, the rectangular platform having a cavity inside, and a limiting groove formed on the inner wall of the cavity; the movable component is disposed within the cavity.

[0010] As a preferred embodiment, the moving component includes a motor, a first lead screw, a second lead screw, and nuts. The motor is fixedly connected to the inner wall of the cavity. One end of the first lead screw is fixedly connected to the output end of the motor. One end of the second lead screw is connected to the other end of the first lead screw. The two nuts are threadedly connected to the first lead screw and the second lead screw, respectively. The first lead screw and the second lead screw have opposite threads.

[0011] As a preferred embodiment, a central ring is fixedly connected to the other end of the first lead screw, and one side of the central ring is fixedly connected to one end of the second lead screw; an extension shaft is fixedly connected to the other end of the second lead screw, one end of the extension shaft passes through the rectangular platform and is rotatably connected to the rectangular platform, and a first sprocket is fixedly connected to one end of the extension shaft.

[0012] As a preferred embodiment, the nut includes a first convex shaft, a hinge rod, and a sliding rod. The first convex shaft is fixedly connected to one side of the nut, one end of the hinge rod is hinged to the circumferential surface of the first convex shaft, and the sliding rod is fixedly connected to the other side of the nut. The sliding rod is slidably connected to the limiting groove.

[0013] As a preferred embodiment, the support plate includes baffles, a second convex shaft, and a fixing rod. Two baffles are fixedly connected to the top of the support plate, the second convex shaft is fixedly connected between the two baffles, the other end of the hinge rod is hinged to the circumferential surface of the second convex shaft, and the fixing rod is fixedly connected between two adjacent support plates.

[0014] As a preferred embodiment, the driven component includes a second sprocket, a transmission chain, a first gear, and a second gear. The second gear is fixedly connected to one end of the rotating shaft, the first gear meshes with the second gear, the second sprocket is fixedly connected to one side of the first gear, and the transmission chain drives the first sprocket and the second sprocket.

[0015] As a preferred embodiment, the driven member further includes a second bushing, a shaft is fixedly connected to one side of the second sprocket, the shaft is rotatably connected to the inner side of the second bushing, and the second bushing is fixedly connected to the support platform.

[0016] Working principle of excitation system simulation platform: When switching the simulation platform from transfer mode to working mode, the motor is started and rotated forward. The motor drives the first and second lead screws to rotate. Since the threads on the first and second lead screws are in opposite directions, the two nuts will move in opposite directions, i.e., move towards the central ring simultaneously. As the nuts move, they drive one end of the hinge rod that is hinged to them to move. Since the other end of the hinge rod is hinged to the support plate, and the support plate is restricted by gravity and the fixed rod, the tilt angle of the hinge rod becomes smaller, thereby driving the support plate to descend until the support plate contacts the ground and supports the entire device, slightly lifting the casters off the ground to enhance the stability of the device.

[0017] Simultaneously, as the second lead screw rotates, the first sprocket at its end rotates synchronously, driving the second sprocket to rotate via a transmission chain. The second sprocket drives the first gear, which is coaxial with it, to rotate. The first gear then drives the second gear meshing with it. Since the diameter of the first gear is smaller than that of the second gear, this constitutes a speed reduction transmission. The second gear is fixed on the rotating shaft, so the rotating shaft begins to rotate slowly. The rotating shaft drives the tilting table to rotate around the axis of the first bushing via a connecting rod until the tilting table rotates to a horizontal working position roughly parallel to the ground, with the display screen and data interface facing the operator. When the device is finished and needs to be switched to the storage state, the motor is started in reverse. At this time, the two nuts move away from the central ring, driving the support plate to rise and reset via the hinge rod. Simultaneously, the above transmission process is reversed, driving the tilting table to rotate in the opposite direction until it is reset, so that the display screen and data interface are no longer exposed.

[0018] Beneficial technical effects of the present invention: This invention addresses the issue of exposure and provides physical protection. By incorporating a linkage mechanism between the tilting platform and the top support assembly, the tilting platform automatically retracts and resets when the equipment is idle or moved. This conceals the display screen, data interfaces, and other precision components inside or towards the inside, effectively preventing damage caused by bumps, dust intrusion, or other factors when the equipment is not in operation. This significantly improves the equipment's lifespan and reliability.

[0019] Improved operational stability. This invention simultaneously drives the tilting platform to unfold, and simultaneously drives the support plate to descend and brace against the ground, stably supporting the equipment and preventing the bottom casters from rolling. This effectively prevents equipment displacement during operation due to accidental collisions or uneven ground, providing a stable platform for simulation operations.

[0020] Easy to operate and with integrated functions. This invention uses a single motor to simultaneously lift and lower the support plate and unfold / fold the tilting table, integrating these two functions into a single drive source, thus simplifying the operation. Users only need to control the forward and reverse rotation of the motor to automatically complete the workstation transitions of the entire platform, making operation convenient and quick.

[0021] The rotation is smooth and the structure is reliable. The rotation speed of the turning table is reduced by the meshing transmission of the first and second gears in the driven component, which ensures the smooth and stable movement of the turning table and avoids impact on the internal precision electronic components.

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1 Reference Figures 1 to 5 As shown, this embodiment provides an excitation system simulation platform, which aims to solve the problem that the display screen and data interface of the existing excitation system simulation platform are easily damaged, and to improve operational stability.

[0030] The simulation platform described in this embodiment includes a flipping component 100 and a top support component 200.

[0031] In this embodiment, the flipping component 100 serves as the support for the operating interface and the main body, including a support platform 101 as a base and a flipping platform 102 disposed on top of the support platform 101. Two flipping platforms 102 are symmetrically arranged along the center line of the support platform 101. The flipping platforms 102 are rotatably connected to the support platform 101, allowing them to flip relative to the support platform 101. The support platform 101 houses heavy test modules that are difficult to flip, such as a small current test module and a demagnetization overvoltage test module. These modules contain components such as transformers and voltage regulators. Placing them at the bottom of the simulation platform lowers the center of gravity, improves the structural stability of the simulation platform, and facilitates transport and movement. The flipping platform 102 houses lighter electronic devices that are not restricted by flipping, such as motherboards and analog circuit boards. The tilting table 102 is located 300mm above the support table 101. This part can be unfolded from the middle, and the whole is in the shape of "T" after unfolding. Buttons, display screen and test line interface are all arranged on the unfolded surface for easy observation and operation.

[0032] In this embodiment, the support platform 101 includes a first bushing 101a, a rotating shaft 101b, and a caster wheel 101c. Multiple first bushings 101a are fixed on both sides of the support platform 101, and the rotating shaft 101b is rotatably connected to the inner side of the first bushings 101a. The caster wheel 101c is fixedly connected to the four corners of the bottom of the support platform 101, which facilitates the transfer of the simulation platform.

[0033] In this embodiment, the top support assembly 200 is responsible for providing stable support for the simulation platform and automatically retracting and unfolding the flip platform 102. It includes rectangular platforms 201 fixedly connected to both sides of the support platform 101, a movable component 202 connected to the rectangular platforms 201, a support plate 203 connected to the movable component 202, and a driven component 204 cooperating with the movable component 202. The two rectangular platforms 201 are symmetrically arranged along the center line of the support platform 101. A cavity 201a is formed through the top of each rectangular platform 201, and a limiting groove 201b is formed on the inner wall of the cavity 201a.

[0034] In this embodiment, the movable component 202 is mainly housed within the cavity 201a and includes a motor 202a, a first lead screw 202b, a second lead screw 202c, and two nuts 202d. The motor 202a is fixedly mounted on the inner wall of the cavity 201a. One end of the first lead screw 202b is fixedly connected to the output shaft of the motor 202a, and its other end is fixedly connected to one end of the second lead screw 202c via a central ring 202b-1. The first lead screw 202b and the second lead screw 202c are of the same length. The first lead screw 202b and the second lead screw 202c are threaded with opposite directions. The two nuts 202d are threadedly connected to the first lead screw 202b and the second lead screw 202c, respectively, and are symmetrically arranged on both sides of the central ring 202b-1. A first convex shaft 202d-1 is fixed to one side of each nut 202d, and a sliding rod 202d-3 is fixed to the other side. The slide bar 202d-3 is inserted into and slides within the limiting slide groove 201b. This structure ensures that the nut 202d can only move along the axial direction of the lead screw when the lead screw rotates, and will not rotate. One end of the hinge rod 202d-2 is hinged to the circumferential surface of the first convex shaft 202d-1.

[0035] In this embodiment, the support plate 203 is located below the rectangular platform 201 and is used to support the ground when needed. Two parallel baffles 203a are fixed to the top of the support plate 203, and a second convex shaft 203b is fixedly connected between the two baffles 203a. The other end of the aforementioned hinge rod 202d-2 is hinged to the circumferential surface of the second convex shaft 203b. To ensure that changes in the inclination of the hinge rod 202d-2 can drive the synchronous lifting and lowering of multiple support plates 203, a fixing rod 203c is also fixedly connected between adjacent support plates 203, serving a linkage and limiting function.

[0036] In this embodiment, the driven member 204 is used to transmit the movement of the moving member 202 to the tilting table 102. Specifically, an extension shaft 202c-1 is fixedly connected to the end of the second lead screw 202c. One end of the extension shaft 202c-1 passes through the side wall of the rectangular table 201 and is rotatably connected to it. A first sprocket 202c-2 is fixedly installed at the end of the extension shaft 202c-1. The driven member 204 includes a second sprocket 204a, a transmission chain 204b, a first gear 204c, and a second gear 204d. The second sprocket 204a is rotatably mounted on the support table 101 through a second bushing 204a-1. Specifically, a shaft is fixedly connected to one side of the second sprocket 204a, and the shaft is rotatably connected to the inside of the second bushing 204a-1. The second bushing 204a-1 is fixedly connected to the support table 101, and the second bushing 204a-1 can provide a limiting and supporting effect for the second sprocket 204a. A transmission chain 204b is wound around a first sprocket 202c-2 and a second sprocket 204a to achieve chain drive. A first gear 204c is coaxially and fixedly connected to the second sprocket 204a. A second gear 204d is fixedly connected to one end of the rotating shaft 101b of the flipping assembly 100 and meshes with the first gear 204c. The rotating shaft 101b is rotatably mounted on the side wall of the support platform 101 via multiple first bushings 101a. A connecting rod 101b-1 is fixedly attached to the circumferential surface of the rotating shaft 101b, and the other end of the connecting rod 101b-1 is fixedly connected to the side wall of the flipping table 102. Thus, when the rotating shaft 101b rotates, it drives the flipping table 102 to flip. Preferably, the diameter of the first gear 204c is smaller than that of the second gear 204d, forming a reduction mechanism, making the flipping process of the flipping table 102 smoother and slower.

[0037] The working principle of this embodiment is as follows: When the simulation platform needs to be switched from the transfer state to the working state, the operator controls motor 202a to rotate forward. Motor 202a drives the first lead screw 202b and the second lead screw 202c to rotate synchronously. Since the threads of the two lead screws rotate in opposite directions, the two nuts 202d, guided by slide rod 202d-3 and limiting slide groove 201b, move towards the central ring 202b-1 along the lead screw axis. As the nuts 202d move, the tilt angle of the hinge rod 202d-2 hinged to them gradually decreases, thereby pushing downward against the support plate 203, causing the support plate 203 to descend and finally stabilize and support the ground. When the support plate 203 fully supports the ground, the caster wheel 101c is off the ground or no longer a major load-bearing component, and the platform is stably supported. In the above process, the rotation of the second lead screw 202c drives the first sprocket 202c-2 to rotate via the extension shaft 202c-1, which in turn drives the second sprocket 204a and the first gear 204c to rotate via the transmission chain 204b. The first gear 204c drives the second gear 204d, which meshes with it, to rotate at a reduced speed, thereby causing the rotating shaft 101b to rotate slowly. The rotation of the rotating shaft 101b is converted into the upward tilting motion of the tilting table 102 via the connecting rod 101b-1, until the tilting table 102 tilts to a horizontal working position, exposing its display screen and data interface for easy operation. When the device is finished and needs to be reset, the control motor 202a reverses. At this time, the two nuts 202d move away from the central ring 202b-1, pulling the support plate 203 upward and resetting it via the hinge rod 202d-2. Simultaneously, the above transmission path reverses, causing the tilting table 102 to tilt in the opposite direction and return to its initial state, effectively protecting its precision components from exposure.

[0038] Example 2 This embodiment provides another possible implementation based on Embodiment 1. Its overall structure is the same as Embodiment 1, the difference being the specific implementation of the driven member 204. For example, the sprocket and chain drive can be replaced with a synchronous belt drive, or a set of bevel gears can be used to achieve power transmission. The key is to transmit the rotation of the extension shaft 202c-1 to the rotating shaft 101b. Furthermore, the moving member 202 can also employ other linear motion mechanisms, such as a lead screw and a guide rod, combined with a slider to achieve the lifting and lowering of the support plate, and then connected to the driven member 204 through a gear and rack mechanism. These simple substitutions and transformations should all be considered within the scope of protection of this invention.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
