In the areas where electricity is consumed, step-down transformers are used to reduce voltage to meet the needs of various electrical devices and safe electricity use. Transformers can also be used to change alternating current, impedance, and phase. A transformer is an electrical device that increases or decreases alternating current while maintaining a constant voltage frequency; it is an indispensable electrical component in modern power transmission.

Most transformers are exposed outdoors without any protective measures, and are exposed to sun and rain for a long time, which reduces the service life of the transformer and also reduces its safety. Therefore, a transformer energized self-locking alarm protection device is designed to solve this problem. Summary of the Invention

[0018] This invention provides a transformer power-on self-locking alarm protection device, which solves the problem that many transformers in existing power equipment are installed outdoors, often resulting in electricity theft or electric shock accidents. Accidents can occur if thieves or maintenance personnel operate improperly, leading to low safety performance. Some transformers have complex structures and are difficult to install. Most transformers are exposed outdoors without any protective measures, and long-term exposure to sun and rain reduces their service life and safety. To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figures 1-8 As shown, a transformer energized self-locking alarm protection device of the present invention includes a transformer body 2. A horizontal plate 16 is fixedly connected to the upper end of the transformer body 2. A self-locking protective cover 1 is provided at the upper end of the horizontal plate 16. Vibration sensors 6 are symmetrically arranged on the inner wall of the self-locking protective cover 1. A conductive mechanism 663 is installed on the upper surface of the horizontal plate 16. The conductive mechanism 663 includes multiple conductive heads 4 equidistantly installed on the upper surface of the horizontal plate 16. One end of the conductive head 4 is connected to a conductive wire 3. The other end of the multiple conductive wires 3 passes through each barrier cylinder 5 and is connected to an energized permanent magnet 30. The operation is controlled by an external controller to conduct electrical energy from the conductive wires 3 to the energized permanent magnet 30, and then the self-locking protection mechanism is activated. When the self-locking protective cover 1 is struck or cut externally, a vibration force will be generated and sensed by the vibration sensor 6. At this time, the connected alarm will sound and automatically alarm, which is beneficial to the protection of the transformer.

[0020] Specifically, multiple limiting slide blocks 23 that slide in cooperation with limiting slide grooves 22 are fixedly connected to both ends of the self-locking protective cover 1. A self-locking protection mechanism 662 is provided on the inner side of the self-locking protective cover 1. The self-locking protection mechanism 662 includes multiple barrier cylinders 5 symmetrically arranged on the inner side of the self-locking protective cover 1, and an energized permanent magnet 30 installed at the bottom of the barrier cylinder 5. A movable rod 25 is movably arranged on the inner side of the barrier cylinder 5. An auxiliary float 32 is fixedly fitted on the outer surface of the movable rod 25. The auxiliary float 32 slides against the inner wall of the barrier cylinder 5. Multiple mounting connectors 33 are inserted through the upper end of the transverse plate 16 and are connected to the transformer body 2. Multiple magnetic chucks 26 are fixedly connected to the bottom end of the movable rod 25. Multiple operating plates 28 connected to the movable rod 25 are fixedly connected to the inner wall of the self-locking protective cover 1. Limiting mechanisms 661 are symmetrically installed on the upper end of the transverse plate 16. 61 includes two sleeves 14 symmetrically fixedly connected to the upper end of the transverse plate 16, and a limiting rod 11 inserted inside the sleeve 14. A spring 24 is fitted on the outer surface of the inner side of the limiting rod 11. A lifting pressure plate 8 is movably fitted on the outer surface of the limiting rod 11. A station plate 15 is symmetrically arranged at the upper end of the transverse plate 16. Two limiting grooves 22 are opened at one end of the station plate 15. When the permanent magnet 30 is energized, it generates a strong magnetism that attracts the magnetic chuck 26, thereby driving the magnetic chuck 26 to slide down inside the barrier cylinder 5, which causes the movable rod 25 to move. After the movable rod 25 moves, it drives the auxiliary float 32 into the barrier cylinder 5 to ensure sealing after entry. At the same time, after the movable rod 25 moves, it drives the operating plate 28 to descend. After the operating plate 28 moves, it causes the self-locking protective cover 1 to move accordingly. During the descent of the self-locking protective cover 1, it drives the limiting slide block 23 to move in the limiting groove 22. The internal sliding mechanism is smooth, and after complete closure, it stops receiving electrical energy from the conductive wire 3. The magnetism remains unchanged, ensuring self-locking and saving energy.

[0021] Specifically, a stabilizing mechanism 665 is symmetrically installed on the upper end of the transverse plate 16. The stabilizing mechanism 665 includes two limiting rods 10 fixedly connected to the upper end of the transverse plate 16, and a limiting sleeve 9 movably fitted on the outer surface of the limiting rods 10. An L-shaped connecting block 19 is fixedly connected to the outer surface of the limiting sleeve 9. The L-shaped connecting block 19 is fixedly connected to the self-locking protective cover 1. The limiting sleeve 9 is fixedly connected to the lifting pressure plate 8. After the self-locking protective cover 1 descends, it drives the L-shaped connecting block 19 to move. After the L-shaped connecting block 19 moves, it drives the limiting sleeve 9 to slide downward on the limiting rod 10. After the limiting sleeve 9 descends, it drives the lifting pressure plate 8 to move. After the lifting pressure plate 8 moves, it compresses the spring 24 and enters the sleeve 14. After the self-locking protective cover 1 descends, it enters the waterproof groove 17 on the transverse plate 16 and overlaps, which is beneficial to the waterproofing of the transformer.

[0022] Specifically, multiple transmission line pipes 34 are fixedly connected to the upper end of the self-locking protective cover 1, and a waterproof soft sleeve 12 is connected to the upper end of the transmission line pipes 34. Ventilation windows 7 are provided at both ends of the self-locking protective cover 1. The ventilation windows 7 provide a convection effect for the heat generated by the transformer inside the self-locking protective cover 1.

[0023] Specifically, a rainproof mechanism 664 is installed at the upper end of the horizontal plate 16. The rainproof mechanism 664 includes two support frames 18 fixedly connected to one end of the horizontal plate 16, and a rainproof edge plate 13 fixedly installed on the upper end of the support frames 18. A plurality of arc-shaped grooves 20 are opened at one end of the rainproof edge plate 13. A soft pad 21 is provided on the inner side of the arc-shaped grooves 20. One end of the limiting rod 10 is fixedly connected to the support frame 18, and one end of the limiting rod 11 is fixedly connected to the support frame 18. A waterproof groove 17 is opened on the upper surface of the horizontal plate 16. The waterproof groove 17 corresponds to the bottom end of the self-locking protective cover 1. When it rains, the rainwater is first blocked by the rainproof edge plate 13, and some of the rainwater outside the self-locking protective cover 1 enters the waterproof groove 17 along the outer edge and is discharged.

[0024] In use, after the protective device is installed, the user first operates an external controller to transfer electrical energy from the conductive wire 3 to the energized permanent magnet 30. The energized permanent magnet 30 generates a strong magnetic field that attracts the magnetic chuck 26, causing it to slide downwards within the barrier cylinder 5. This movement drives the movable rod 25, which in turn moves the auxiliary float 32 into the barrier cylinder 5, ensuring a tight seal. Simultaneously, the movement of the movable rod 25 causes the operating plate 28 to descend, which in turn moves the self-locking protective cover 1. During the descent of the self-locking protective cover 1, the limiting slide block 23 slides smoothly within the limiting groove 22. The descent of the self-locking protective cover 1 then moves the L-shaped connecting block 19, which in turn moves the limiting sleeve block 9, which slides downwards on the limiting rod 10. After the limit sleeve 9 descends, it drives the lifting pressure plate 8 to move. After the lifting pressure plate 8 moves, it compresses the spring 24 and enters the sleeve 14. After descending, the self-locking protective cover 1 enters the waterproof groove 17 on the horizontal plate 16 and overlaps. When it rains, the rainwater is first blocked by the rain baffle plate 13. Some of the rainwater outside the self-locking protective cover 1 enters the waterproof groove 17 along the outer edge and is discharged. After it is fully closed, the closing 29 stops the input of electrical energy from the conductive wire 3. The magnetism remains unchanged. When the self-locking protective cover 1 is knocked or cut from the outside, it will generate a vibration force that is detected by the vibration sensor 6. At this time, the connected honeycomb device will sound and then automatically alarm. The ventilation window 7 creates a convection effect on the heat generated by the transformer inside the self-locking protective cover 1, which is conducive to the self-locking of the transformer and prevents theft. To prevent thieves from replacing or damaging the transformer's connection lines and to ensure electrical safety, when power personnel operate the transformer, the magnetic switch of the energized permanent magnet 30 is turned off from the external controller. After the energized permanent magnet 30 loses its magnetism, the spring 24 resets and pushes the lifting plate 8 to rise. After the lifting plate 8 rises, it slides on the limiting rod 11. After the lifting plate 8 moves, it drives the limiting sleeve 9 to rise and slide on the limiting rod 10. After the limiting sleeve 9 slides, it drives the L-shaped connecting block 19 to move. After the L-shaped connecting block 19 moves, it drives the self-locking protective cover 1 to rise and lift. After the self-locking protective cover 1 is lifted, personnel operate the transformer and insert the replacement line through the waterproof soft sleeve 12 into the transmission line conduit 34, thereby connecting it with the auxiliary float 32, which is beneficial for the maintenance and protection of the transformer.
