Description

Technical Field

[0001] This utility model relates to a vibration and tilting simulation system for power switchgear, belonging to the field of earthquake simulation and demonstration technology. Background Technology

[0002] Power switchgear is widely used in power systems for controlling, protecting, and distributing power. With the development of power grids and the increasing demand for intelligent systems, the safety and stability of power switchgear have become critical issues. In the face of natural disasters (such as earthquakes and typhoons) or external forces (such as mechanical collisions), switchgear may experience severe vibrations and tip over, thus affecting the normal operation of the power system. Therefore, it is necessary to design a system to simulate the tipping of power switchgear under different impacts, improving the handling capabilities of personnel in such situations.

[0003] Currently, operators of power switchgear may be unable to perform correct operations during natural disasters, potentially affecting the normal operation of the power system. While current simulations of power switchgear tilting due to earthquakes provide some detail on the specific devices, they are insufficient to fully simulate the overall movement and trends of the switchgear under earthquake conditions, resulting in inconsistent and discontinuous movement.

[0004] Therefore, it is necessary to design a power switchgear vibration and tilting simulation system that can simulate the vibration and tilting of power switchgear in the face of various emergencies, and improve the operators' ability to handle accidents caused by vibration or tilting of various types. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a power switchgear vibration and tilting simulation system, which solves the problem of inconsistent motion state of power switchgear during simulated earthquake.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: a vibration and tilting simulation system for power switchgear, comprising...

[0007] Supporting devices, power units, and switchgear.

[0008] The power unit is installed inside the support device, and the switch cabinet is installed on top of the support device.

[0009] The support device includes a support frame, a slide rail, and a mounting platform. The slide rail is disposed on the top of the support frame, and the mounting platform is disposed on the slide rail. The mounting platform can move along the surface of the slide rail.

[0010] The power unit includes a motor, the bottom of which is disposed inside the support frame, and the top of which is connected to the slide rail. The motor is capable of driving the slide rail to move.

[0011] The switch cabinet includes a cabinet body, a cabinet door, and an opening and closing device. The cabinet body and the cabinet door are connected by the opening and closing device, which controls the offset of the cabinet door. The cabinet body is located on the top of the mounting platform.

[0012] Preferably, the support frame and the slide rail are connected by a bearing seat.

[0013] Preferably, a baffle is provided on the top of the bearing housing.

[0014] Preferably, a contact pulley is provided on the top of the motor, and one end of the contact pulley is fixed to the bottom of the slide rail.

[0015] Preferably, when the motor is in its initial state, the side of the slide rail connected to the bearing seat is higher than the side of the slide rail connected to the motor. At this time, the top of the mounting platform is horizontal, and the mounting platform is close to the motor.

[0016] Preferably, after the motor is started, the mounting platform can move along the slide rail toward the bearing seat.

[0017] Preferably, one end of the opening and closing device is fixed to the side of the cabinet body, and the other end is fixed to the inside of the cabinet door.

[0022] (3) With this invention, the slide rail is fixed on the support frame, and the bearing seat provides rotation pointers for the slide rail, allowing the mounting platform to slide on the slide rail. Driven by the power unit, the mounting platform can move back and forth on the slide rail, simulating the sliding caused by the tilting of the ground during an earthquake, achieving both tilting and sliding simulation effects. Simultaneously, a baffle is installed on the bearing seat to ensure that the mounting platform will not fall off the slide rail, guaranteeing the reliable operation of the entire device.

It can completely simulate the possible states of the cabinet body under different working conditions. Attached Figure Description

[0035] The power unit 2 is installed at the bottom of the support device 1 to drive the slide rail to move, thereby simulating the tilting and vibration of the switch cabinet 3.

[0036] The switch cabinet 3 is fixed on the mounting platform, and the opening and closing of the cabinet door is controlled by the opening and closing device 4 to simulate the impact of the opening and closing of the cabinet door on the overall stability during actual operation.

[0037] The support frame 11 of the support device 1 is a rectangular metal frame structure, welded or assembled from materials such as shaped steel or square tubing. In this embodiment, the support frame 11 is assembled using bolts. The support frame 11 provides basic structural support and stability for the entire system, and space is reserved inside the support frame 11 to fix the power unit 2.

[0038] A boss 12 is provided on one side of the top of the support frame 11. The boss 12 forms a stepped structure and is fixed to the top of the support frame 11 by bolts. The boss 12 can provide a bearing or positioning surface in a local position, which facilitates the installation of components such as bearing housing 3.

[0039] A bearing seat 13 is provided on the top of the boss 12. The bearing seat 13 is a bearing fixing seat made of metal, and a bearing is provided inside the bearing seat 13 to provide a fulcrum for rotation. The bearing seat 13 can be connected and cooperate with the slide rail 15 to provide support for the slide rail 15.

[0040] A baffle 14 is also provided on the top of the bearing housing 13. The baffle 14 has an L-shaped structure and multiple reinforcing ribs on its back. The baffle 14 can limit the movement range of the mounting platform 16 moving on the slide rail 15, thus serving as a limit and preventing excessive displacement or derailment.

[0041] The slide rail 15 is a long, narrow track structure. A guide rail is provided on the surface of the slide rail 15. One end of the slide rail 15 is connected to the bearing seat 13, and the bottom of the other end is connected to the power device 2. In this embodiment, a slide rail platform 17 is provided on the surface of the slide rail 15, and the slide rail platform 17 can move along the surface of the slide rail 15. The end of the slide rail 15 connected to the bearing seat 13 is fixed, and the slide rail 15 can rotate along the bearing seat 13. The power device 2 can control the rotation angle of the slide rail 15.

[0042] The slide rail platform 17 is set on the surface of the slide rail 15. The slide rail platform 17 can provide a support surface to fix the mounting platform 16, thereby improving the overall structural stability and adjustability.

[0043] In this embodiment, the mounting platform 16 is fixed to the top of the slide rail platform 17. The mounting platform has a frame structure, and the top of the mounting platform 16 is a flat surface. The switch cabinet 3 can be fixed to the top of the mounting platform 16. When the slide rail 15 shifts, the mounting platform 16 can be driven by the slide rail platform 17 to move on the slide rail 15.

[0044] In this embodiment, the power unit 2 is in its initial state, and the slide rail 15 is located on one side of the bearing seat 13, which is higher than the side connected to the power unit 2. At this time, the slide rail platform 17 is close to the side of the power unit 2, and the top of the mounting platform 16 fixed on the slide rail platform 17 is in a horizontal state.

[0045] The power unit 2 includes a motor bracket 21, a motor 22, a motor baffle 23, and a contact pulley 24. The motor bracket 21 is located inside the support frame 11, on the side away from the bearing seat 13. The motor bracket 21 is an L-shaped metal bracket that provides stable support and is bolted to the support frame 11.

[0046] The motor 22 is housed inside the motor bracket 21. In this embodiment, the motor 22 is a servo motor, which provides power output to drive the slide rail 15 to move, thereby simulating the tipping process caused by vibration. An output shaft is located at the top of the motor 22, and a contact pulley 24 is located at the top of the output shaft.

[0047] The surface of the motor bracket 21 is also provided with a motor baffle 23, which can fix the motor 22. The motor baffle 23 is fixed on the top of the motor 22 to protect the overall stability of the motor 22 during operation.

[0048] A contact pulley 24 is provided on the top of the motor 22. The top of the contact pulley 24 is a wheel-shaped component with a bearing, and the bottom of the contact pulley 24 is fixed to the output shaft on the top of the motor 22. The top of the contact slide rail 24 is connected to the slide rail 15 by rolling. When the motor 22 drives the output shaft to move, the contact pulley 24 can push one side of the slide rail 15 to rise. Through the rolling connection between the contact pulley 24 and the slide rail 15, wear can be reduced and the overall durability of the device can be improved.

[0049] Driven by the power unit 2, the slide rail 15 can move along the set trajectory, driving the mounting platform 16 to move on the slide rail 15, thereby simulating the vibration or tilting effect that the switch cabinet set on the top of the mounting platform 16 may produce in the event of an earthquake or other situations.

[0050] The switchgear 3 includes a cabinet body and cabinet doors, which are connected by an opening and closing device 4. The cabinet body is a rectangular metal cabinet, simulating the main body of a power switchgear. Corresponding cabinet doors are located on the front side of the cabinet body. The cabinet body and cabinet doors, when combined, form a simulated power switchgear. The opening and closing device 4 is located between the cabinet body and the cabinet doors, and can drive the cabinet doors to open or close.

[0051] Reference Figure 6 The opening and closing device 4 includes a push rod bracket 41, a push rod 42, a rotating shaft 43, a locking plate 44, a follower arm 45, and an active arm 46. The opening and closing device 4 can control the relative opening and closing position between the cabinet door and the cabinet body.

[0052] The push rod bracket 41 is a U-shaped bracket, fixed to the inside of the cabinet. The push rod bracket 41 provides a base for fixing the push rod 42 and related structures, ensuring sufficient support strength during opening and closing. In this embodiment, the push rod bracket 41 is fixed to the inside of the cabinet with bolts.

[0053] In this embodiment, the push rod 42 is an electric push rod, which can extend and retract under the action of electricity, thereby driving the cabinet door to open or close. One end of the push rod 42 is fixed to one side of the push rod bracket 41 by bolts, and the other end is in contact with the active arm 46.

[0054] A rotating shaft 43 is provided inside the push rod bracket 41. The rotating shaft 43 is connected to the active arm 46. The bottom of the active arm 46 is connected to the push rod 42. Driven by the push rod 42, the active arm 46 can rotate around the rotating shaft 43 and move with the moving arm 45.

[0055] One end of the follower arm 45 is connected to the drive arm 46, and the other end is equipped with a locking plate 44. Driven by the drive arm 46, the follower arm 45 can drive the cabinet door to rotate and adjust the angle of the cabinet door.

[0056] The bottom of the locking plate 44 is fixed to the inside of the cabinet door by bolts, and the top of the locking plate 44 is connected to the follower arm 45.

[0057] With the cooperation of the opening and closing device 4, the cabinet door fits tightly against the cabinet body when closed, forming a whole; when open, the cabinet door can be opened outward to allow operation or inspection of the internal equipment. Furthermore, in conjunction with vibration and tilting simulations, the impact of the cabinet door's opening or closing state at different tilt angles and vibration frequencies on system stability can be observed.

[0058] The overall installation process in this embodiment is as follows:

[0059] 1. Fix the motor bracket 21 in the power unit 2 inside the support frame 11 near the edge, and fix the motor 22 inside the motor bracket 21 through the motor baffle 23. Install the contact pulley 24 on the top of the motor 22.

[0060] 2. A boss 12, a bearing seat 13, and a baffle 14 are provided on the side of the support frame 11 away from the power unit 2, and one end of the slide rail 15 is fixed to the bearing seat 13.

[0061] 3. The mounting platform 16 is mounted onto the surface of the slide rail 15, and a slide rail platform 17 is provided at the connection between the mounting platform 16 and the slide rail 15 for auxiliary fixation.

[0062] 4. The switch cabinet 3 is fixed on the top of the mounting platform 16, and the opening and closing device 4 is installed between the cabinet body and the cabinet door of the switch cabinet 3.

[0063] The power transmission process in this embodiment:

[0064] 1. When the motor 22 is in the initial state, that is, the state when it is not started, the side of the slide rail 15 near the bearing seat 13 is higher than the side connected to the motor 22. At this time, the mounting platform 16 is close to the side of the motor 22 and ensures that the top is level.

[0065] 2. After starting the motor 22, the motor 22 gradually rises, and the contact pulley 24 pushes the slide rail 15, controlling the slide rail 15 to rotate along the bearing seat 13. At this time, the mounting platform 16 fixed on the slide rail 15 moves in a predetermined direction, and the switch cabinet set on the mounting platform 16 is displaced and tilted at a certain angle.

[0066] 3. During the tilting or vibration simulation, the push rod 42 can be controlled to open or close the cabinet door, simulating different situations that the cabinet door will cause under different conditions.

[0067] In this embodiment, when the motor 22 drives the slide rail 15 to move, the mounting platform 16 can slide on the slide rail 15. At this time, the switch cabinet 3 exhibits a sliding and tilting effect.
