Technical Field
[0001] This utility model relates to the field of experimental platform technology, specifically a multifunctional relay protection experimental platform. Background Technology
[0002] The Power System Relay Protection Comprehensive Experiment Platform integrates the teaching content of various professional courses in higher education institutions, such as "Relay Protection," "Electrical Equipment," "Automatic Devices," "Factory Power Supply," and "Power System Microcomputer Protection." It provides dozens of common relay protection experiments and training, including relay characteristics, relay protection, integrated relay protection, and secondary circuits, and can train students' professional skills in a realistic and intuitive experimental teaching format.
[0003] However, existing devices cannot adjust the table area according to different usage needs. Relay protection experiments may involve testing a single relay, commissioning multiple protection devices, or simulating complex power grids. A fixed table area may result in insufficient space, such as the inability to place large experimental equipment. Therefore, we propose a multi-functional relay protection experimental platform to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional relay protection experimental platform to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional relay protection experimental platform, comprising a platform body, with fixed sleeves fixedly connected to both the left and right sides of the platform body, and support rods inserted into the fixed sleeves; a storage frame is inserted and snapped into the lower end of the platform body; extension plates are inserted into both the left and right sides of the upper end of the platform body; a base is fixedly connected to the middle position of the upper end of the platform body, and a moving rod is snapped into the base; a connecting plate is sleeved on the moving rod; an electric push rod is fixedly installed on the left side of the moving rod; a placement plate is fixedly connected to the upper end of the connecting plate; a fixed rod is fixedly connected to the back side of the platform body, and a movable rod is sleeved on the fixed rod; a movable sleeve is sleeved on the upper end of the movable rod, and a lighting lamp is connected to the lower end of the movable sleeve.
[0006] Preferably, the outer surface of the support rod is uniformly provided with threaded grooves, the support rod is threadedly inserted into the fixed sleeve, and a rubber pad is fixedly connected to the lower end of the support rod.
[0007] Preferably, both ends of the storage frame are movably engaged with the platform body by T-shaped locking blocks, and the platform body has T-shaped slots that cooperate with the T-shaped locking blocks.
[0008] Preferably, the extension plate is movably inserted into the platform body, and the platform body has a slot that mates with the extension plate, and a rubber ball is fixedly connected to the inner wall of the slot, and the extension plate has a groove that mates with the rubber ball.

[0011] Preferably, the lower end of the movable sleeve is connected to a lighting lamp via a ball joint.
[0012] This utility model provides a multifunctional relay protection experimental platform, which has the following beneficial effects:
[0013] The platform features pluggable extension plates on both sides, allowing for quick adjustment of the work surface area based on experimental scale. Inserting the extension plates expands the operating area, accommodating multiple protection devices or complex wiring requirements. The position of the connecting and placement plates can be adjusted laterally via an electric push rod, adapting to different equipment layouts or operator habits. An internal storage compartment with snap-fit mechanisms stores experimental accessories (such as wires, tools, and spare relays), preventing desktop clutter and maintaining a clean experimental environment. Support rods can be secured with straps or hooks to the extension plates or temporary equipment, reducing desktop space usage. The electric push rod allows for remote or one-button control of the extension and retraction of the moving rod, avoiding the risk of accidental activation during manual adjustments. This design is particularly suitable for high-frequency experiments or hazardous scenarios (such as high-voltage testing).
[0014] Temporarily place the relay under test or debugging equipment, expand wiring or place auxiliary equipment, clearly divide the area to reduce interference, and the movable rod and movable sleeve on the back fixed rod can adjust the height and angle of the lighting to ensure that the light is focused on the experimental area and avoid shadows blocking key components (such as indicator lights and dials). The detachable lighting supports supplemental local lighting, which improves the accuracy of operation, especially when the laboratory is poorly lit or when conducting experiments at night.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 This utility model provides a technical solution: a multifunctional relay protection experimental platform, including a platform body 1, with fixed sleeves 2 fixedly connected to both the left and right sides of the platform body 1, and support rods 3 inserted into the fixed sleeves 2. A storage frame 4 is inserted and snapped into the lower end of the platform body 1. Extension plates 5 are inserted into both the left and right sides of the upper end of the platform body 1. A base 6 is fixedly connected to the middle position of the upper end of the platform body 1, and a moving rod 7 is snapped into the base 6. A connecting plate 8 is sleeved on the moving rod 7. An electric push rod 9 is fixedly installed on the left side of the moving rod 7. A placement plate 10 is fixedly connected to the upper end of the connecting plate 8. A fixed rod 11 is fixedly connected to the back side of the platform body 1, and a movable rod 12 is sleeved on the fixed rod 11. A movable sleeve 13 is sleeved on the upper end of the movable rod 12, and a lighting lamp 14 is connected to the lower end of the movable sleeve 13.
[0024] The outer surface of the support rod 3 is uniformly provided with threaded grooves. The support rod 3 is threaded into the fixed sleeve 2. A rubber pad is fixedly connected to the lower end of the support rod 3. The threaded groove and the fixed sleeve 2 have a self-locking characteristic. After the support rod 3 is adjusted to the target height, it will not automatically slide down due to experimental vibration or equipment weight, ensuring the stability of the table. The rubber pad at the lower end of the support rod 3 provides friction and cushioning effect, preventing the platform from tilting or shifting due to uneven ground or slight vibration. It is especially suitable for smooth laboratory tabletops or outdoor environments.
[0025] Both ends of the storage box 4 are movably engaged with the platform body 1 via T-shaped locking blocks. The platform body 1 has T-shaped slots that cooperate with the T-shaped locking blocks. After the T-shaped locking blocks are inserted into the T-shaped slots, their structural characteristics (high lateral resistance and easy longitudinal disassembly) enable quick installation and fixation. Users can assemble and disassemble the storage box 4 without tools, saving operation time. During the experiment, users may need to frequently access the tools or accessories inside the storage box 4. The T-shaped locking block design allows for one-handed operation for assembly and disassembly, improving efficiency.
[0026] The extension plate 5 is movably inserted into the platform body 1, and the platform body 1 has a slot that matches the extension plate 5. A rubber ball is fixedly connected to the inner wall of the slot, and the extension plate 5 has a groove that matches the rubber ball. When the extension plate 5 is inserted into the slot of the platform body 1, the rubber ball will spring into the groove on the extension plate 5 to achieve automatic locking. Users can fix the extension plate 5 without additional tools or complicated operations, saving time. The rubber ball has a certain elasticity and friction, which can not only firmly fix the extension plate 5, but also prevent the groove from wearing or loosening due to long-term use. Even if the platform is slightly vibrated, the extension plate 5 will not accidentally slip out.
[0027] The fixed rod 11 is designed in a cross shape. The lower end of the movable rod 12 is movably sleeved on the fixed rod 11. The movable rod 12 has a cross-shaped slot that mates with the fixed rod 11. The movable sleeve 13 is movably sleeved on the upper end of the movable rod 12. The movable rod 12 is designed in an L-shape. The movable sleeve 13 has a slot that mates with the movable rod 12. The lower end of the movable sleeve 13 is connected to a light lamp 14 via a ball joint. The cross-shaped structure of the fixed rod 11 allows the movable rod 12 to slide or rotate freely in four directions (front, back, left, and right) to adapt to different experimental scenarios. To meet the lighting needs, the L-shaped design of the movable rod 12 allows it to move up and down along the fixed rod 11 (to adjust the height) and rotate through the cross-shaped slot (to adjust the horizontal direction), thus achieving three-dimensional positioning of the lighting lamp 14. The cross-shaped slot on the movable rod 12 cooperates with the fixed rod 11 to ensure that the lighting lamp 14 is stable after adjustment, avoiding light displacement caused by experimental vibration or touch. The lighting lamp 14 is connected to the movable sleeve 13 through a universal ball, which can adjust the light direction at a small angle (such as tilting or rotating), while absorbing slight vibrations and maintaining the stability of the light source.
[0028] Working principle: The support rod 3 is inserted into the fixing sleeve 2 through the threaded groove. The platform height can be adjusted by manual rotation. The rubber pad provides anti-slip cushioning to ensure the platform is stable and does not wobble during the experiment. The extension plates 5 on the left and right sides are inserted into the platform body 1 through slots. The rubber locking balls automatically lock the platform. When it is necessary to expand the platform, the extension plates 5 are inserted. After the experiment is completed, the extension plates 5 are pulled out to reduce the space occupied. They are fixed under the platform body 1 by T-shaped blocks for storing tools or accessories. They can be quickly disassembled when needed to free up space or access internal items. The base 6 is fixed in the center of the platform body 1. The moving rod 7 can slide laterally on the base 6 through the locking structure. The electric push rod 9 pushes the moving rod 7 to move left and right, driving the connecting rod. The connecting plate 8 and the placement plate 10 move synchronously to achieve rapid adjustment of the equipment position. The relay or tester is placed on the placement plate 10 and its position is adjusted by the electric push rod 9 for easy wiring or observation. The fixed rod 11 is cross-shaped, allowing the movable rod 12 to slide or rotate in four directions. The movable rod 12 is L-shaped and can move up and down or rotate on the fixed rod 11 through the cross-shaped slot to adjust the height and horizontal angle of the lighting lamp 14. The movable sleeve 13 is fitted onto the upper end of the movable rod 12 through the slot to further fine-tune the vertical angle of the lighting lamp 14. The lighting lamp 14 is connected to the movable sleeve 13 through a universal ball, which can flexibly adjust the direction of the light (such as tilting or rotating) while absorbing vibration and maintaining the stability of the light source.
