Description

Technical Field

[0001] This utility model belongs to the field of voltage protection technology, and specifically relates to an intelligent anti-power-loss protection device for a three-phase three-wire system. Background Technology

[0002] Voltage, also known as potential difference, is a physical quantity that measures the energy difference of a unit charge in an electrostatic field due to the difference in electric potential. The magnitude of voltage from one point to another is equal to the work done by a unit positive charge moving from one point to another under the action of the electric field force. The direction of voltage is defined as from high potential to low potential.

[0003] Most existing power failure protection devices are installed using bolts. Bolted connections usually require specific tools, such as screwdrivers and wrenches, for disassembly, increasing the complexity of disassembly, especially in areas with limited space or difficult access. Disassembly of bolted connections takes time, particularly when there are many bolts or the connections are tightly packed. This can reduce the efficiency of maintenance or repair work and increase the workload of maintenance personnel. During disassembly, if improper tools or disassembly methods are used, bolts or surrounding equipment components can easily be damaged. This not only increases maintenance costs but may also affect the overall performance of the equipment, making the disassembly of the power failure protection device more difficult.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This utility model embodiment provides an intelligent anti-power-loss protection device for a three-phase three-wire system, including a base plate 1, exemplarily, such as... Figures 1-6 As shown.

[0026] The base plate 1 has a main unit 2 on its front side. The bottom right side of the main unit 2 is electrically connected to an inlet cable 3, and the inside of the inlet cable 3 is electrically connected to an inlet head 4. The bottom left side of the main unit 2 is electrically connected to an outlet cable 5, and the inside of the outlet cable 5 is electrically connected to an outlet head 6. The bottom of the main unit 2 is electrically connected to a switch controller 7 and a charging port 8. The switch controller 7 is located in front of the charging port 8. Square blocks 9 are fixedly connected to both sides of the main unit 2. Two housings 10 are embedded in one side of the square blocks 9. Two fixing blocks 11 are fixedly connected to the surface of the housings 10. A locking mechanism 12 is provided inside the housings 10.

[0027] The locking mechanism 12 includes a fixing post 121 disposed in the inner cavity of the housing 10, such as Figures 3-6 As shown.

[0028] One end of the fixing post 121 is fixedly connected to the base plate 1. A short rod 122 is fixedly connected to the front end of the fixing post 121. A spherical block 123 is fixedly connected to one end of the short rod 122. A sleeve block 124 is sleeved on the surface of the short rod 122. A movable plate 125 is slidably connected to the inner cavity of the fixing block 11. A first spring 126 is fixedly connected to one side of the movable plate 125. One end of the first spring 126 is fixedly connected to the fixing block 11. A locking block 127 is fixedly connected to one side of the movable plate 125. One side of the locking block 127 extends into the inner cavity of the housing 10 and is located between the sleeve block 124 and the spherical block 123.

[0029] Specifically, the locking mechanism 12 makes the disassembly of the main unit 2 extremely simple. Users can simply push the main unit 2 to release the fixation between it and the base plate 1 without using complicated tools or performing tedious steps, which greatly reduces the difficulty of disassembly. Users can easily disassemble the main unit 2 for cleaning, inspection or replacement of damaged parts, thereby extending the service life of the equipment.

[0030] The fixing block 11 has sliding grooves 13 on both sides of its inner cavity, such as... Figures 1-6 As shown.

[0031] The inner cavity of the slide groove 13 is slidably connected to a slider 14. One side of the slider 14 is fixedly connected to a moving plate 125. One side of the inner cavity of the housing 10 is fixedly connected to a second spring 15. One end of the second spring 15 is fixedly connected to a baffle 16. The top and bottom of the rear side of the square block 9 are both fixedly connected to telescopic rods 17. The output end of the telescopic rod 17 is fixedly connected to a round block 18. One side of the round block 18 is fixedly connected to a protective pad 19. The protective pad 19 is circular in shape. The first spring 126 and the moving plate 125 form a telescopic structure. The maximum moving distance of the moving plate 125 is equal to the deformation of the first spring 126. Both sides of the sleeve block 124 are provided with inclined surfaces, and the inclined surfaces are smooth.

[0032] Specifically, the sliding groove 13 and the slider 14 work together to limit the movement of the moving plate 125, improving the stability of the moving plate 125 during movement. The second spring 15 and the baffle 16 work together to make the baffle 16 contact the spherical block 123. The elasticity of the second spring 15 makes the locking block 127 and the spherical block 123 in close contact, making the main unit 2 more stable when placed. The telescopic rod 17 and the round block 18 provide sufficient support between the base plate 1 and the square block 9, enhancing the tightness of the contact between the locking block 127 and the spherical block 123. The protective pad 19 reduces the contact between the round block 18 and the base plate 1, making the base plate 1 or the round block 18 less prone to wear.

[0033] The working principle of the intelligent power failure protection device for a three-phase three-wire system proposed in this embodiment is as follows:

[0034] When using this device, first check if the main unit 2 has a full charge. Then, disconnect the A-phase wire from the acquisition terminal and connect the A-phase wire to the A interface on the input connector 4. Next, connect the A-phase output side of the output connector 6 to the A-phase of the acquisition terminal. Then, disconnect the B-phase wire in sequence and repeat the above steps. After the connection is completed, reinstall the C-phase wire. After installation, the voltage of the phase wire can be viewed in the AC sampling information of the real-time data of the acquisition terminal, thus completing the connection between the main unit 2 and the acquisition terminal.

[0035] When the main unit 2 needs to be disassembled, simply push the main unit 2. The main unit 2 moves the square block 9, which in turn compresses the telescopic rod 17 and the housing 10. As the housing 10 moves, the spherical block 123 comes into close contact with the baffle 16, thus compressing the second spring 15. Simultaneously, the housing 10 moves the locking block 127 backward. When one side of the locking block 127 contacts the sleeve block 124, the inclined surface of the sleeve block 124 causes the locking block 127 to slide into the inner cavity of the fixed block 11. The locking block 127 moves the moving plate 125, which in turn compresses the first spring 126. When the locking block 127 enters the inner cavity of the fixed block 11, the housing 10 continues to move backward. When the locking block 127 is located behind the sleeve block 124, the first spring 126 compresses the second spring 126. The rebound force of spring 126 will drive the locking block 127 into the inner cavity of housing 10. At this time, the main unit 2 moves forward, the main unit 2 drives the square block 9 to move, the square block 9 drives the housing 10 to move, the housing 10 drives the locking block 127 to move, and the locking block 127 drives the sleeve block 124 to slide on the surface of short rod 122. When one side of the sleeve block 124 contacts the spherical block 123, the sleeve block 124 can enter the inner cavity of the spherical block 123. Continue to move housing 10 forward, and through the setting of the inclined surface of sleeve block 124, the locking block 127 can be driven to slide into the inner cavity of fixed block 11. The locking block 127 drives the moving plate 125 to move, and the moving plate 125 drives the first spring 126 to compress. When the locking block 127 enters the inner cavity of fixed block 11, continue to move the main unit 2 forward, and it can be removed.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
