Description

Technical Field

[0001] The present invention relates to the technical field of voltage-stabilized power supplies, in particular to a voltage-stabilized power supply with an over-temperature protection function. Background Art

[0002] A smart grid is a new type of power grid that integrates sensing, measurement, communication, control, and energy and power technologies. It boasts self-healing, interactivity, compatibility, and high efficiency. It monitors grid status in real time, automatically isolates faults, supports renewable energy integration, and interacts with users to optimize resource allocation. A regulated power supply is an electronic device that converts unstable voltage into stable AC or DC power. Smart grids require regulated power supplies to ensure grid stability and reliability, particularly in distributed generation and microgrids. Regulated power supplies can balance voltage fluctuations and support the integration of renewable energy. Leveraging smart grid communication and control technologies, regulated power supplies enable remote monitoring, fault diagnosis, and energy scheduling optimization, further enhancing the intelligence of power supplies. The core function of a regulated power supply is to maintain a constant output voltage through voltage regulation circuitry despite grid voltage fluctuations or load changes.

[0003] Most three-phase regulated power supplies require a bracket to secure them to the ground. In humid or dusty environments, the bracket can elevate the device, reducing direct contact between moisture and dust and extending its service life. However, the bracket is typically fixed in place, making it difficult to move. Adjusting the position or troubleshooting the regulated power supply may require removing screws and re-drilling holes, increasing workload. The bracket can also restrict access to the bottom or back of the device, making wiring or component inspection difficult. Maintenance may require partial bracket removal, increasing time. When the bracket lifts the device off the ground, the space between the bottom and the ground is limited. Inspection of the bottom terminals, cooling fans, or capacitor components requires technicians to crouch or use tools, significantly reducing efficiency. Some regulated power supplies have input / output ports and switches located on the back of the device. Once the bracket is secured, the back may press against the wall or mounting surface, requiring the device to be disassembled for operations like plugging and unplugging cables or replacing fuses, further increasing maintenance time.

[0024] In the above embodiment, the threaded rod 6 of the lifting assembly 2 rotates synchronously, and then the support block 8 on the threaded block 7 raises the height of the voltage-stabilized power supply body 1 to keep it away from the ground, effectively reducing the entry of impurities such as dust and flocs on the ground into the equipment, and avoiding the risk of poor heat dissipation or short circuit due to dust accumulation.

[0025] Please refer to the Figures 1 to 8 , a voltage-stabilized power supply with over-temperature protection function, a locking mechanism 9, the locking mechanism 9 is arranged on the lifting mechanism and the voltage-stabilized power supply body 1, the locking mechanism 9 includes a fixing component 10 and a limiting component 17, the limiting component 17 is arranged on the fixing component 10, the limiting component 17 includes a card slot 19 and a card block 20, the card block 20 is stuck in the card slot 19 during the rising process, and the locking mechanism 9 is used to quickly lock and fix the voltage-stabilized power supply body 1 during the automatic height adjustment process of rising.

[0026] In the above embodiment, through the mutual cooperation between the card slot 19 and the card block 20, the voltage-stabilized power supply body 1 is limited in multiple directions in the vertical and horizontal directions during the rising process, ensuring that the power supply can be stably supported at different heights, thereby improving the stability, safety and adaptability of the equipment.

[0028] As the preferred implementation of this solution, please refer to Figure 1 as well as Figures 4 to 7A voltage-stabilized power supply with an over-temperature protection function further includes: a limiting component 17. The limiting component 17 of the locking mechanism 9 also includes a through groove 18 that is provided on the fixed block 11. The through groove 18 is interconnected with the slide groove 13.

The inclination angle of the inclined surface B21 is the same as the inclination angle of the inclined surface A16. A horizontal surface 22 is provided at the bottom of the clamping block 20.

A movable cavity 24 is provided on the movable block 23. A fixed plate 25 is provided in the movable cavity 24. Both ends of the fixed plate 25 are fixedly connected to the groove wall of the through groove 18.

[0029] In the above embodiment, when the voltage-stabilized power supply body 1 is lifted by the lifting component 2, the limiting component 17 is repeatedly squeezed and popped out on the fixing component 10, prompting the card block 20 to be locked in the card slot 19 at different heights. The intermittent locking can make the voltage-stabilized power supply body 1 stably supported after being lifted to different heights, and the height of the voltage-stabilized power supply body 1 can be adjusted to meet the connection requirements of different devices.

[0030] Furthermore, a through hole 26 is formed through the fixed plate 25, and a through rod 27 is slidably disposed within the through hole 26. One end of the through rod 27 is fixedly connected to the wall of the through slot 18 on the side near the block 20. A spring 28 is sleeved on the outer surface of the through rod 27, and the spring 28 is positioned between the fixed plate 25 and the wall of the through slot 18 on the side near the block 20. A movable frame 29 is slidably disposed on the outer surface of the fixed block 11, and an arc block 30 is fixedly disposed on the inner wall of the top end of the movable frame 29. An arc slot 31 is formed through the fixed block 11 directly below the arc block 30, and the size of the arc slot 31 is adapted to the size of the arc block 30. A second through hole 32 is formed through the bottom of the movable frame 29, and a fixing rod 33 is slidably provided in the second through hole 32. The end of the fixing rod 33 is fixedly connected to the bottom of the fixed block 11, and a second spring 34 is sleeved on the fixing rod 33. The second spring 34 is located between the fixed block 11 and the movable frame 29, and an extrusion block 35 is fixedly provided at the bottom of the fixed block 11.

[0031] In the above embodiment, the arc block 30 is inserted into the arc groove 31, causing the block 20 to disengage from the groove 19. At this time, the lifting assembly 2 can lower the voltage-stabilized power supply body 1 to a suitable height for maintenance operations, thereby realizing rapid unlocking and height adjustment of the equipment, and facilitating maintenance operations.

[0032] Through all the above embodiments, the working principle of the present invention is: The working process of the lifting component 2 lifting the voltage-stabilized power supply body 1 is as follows: after starting the external drive motor of the threaded rod 6, the two threaded rods 6 begin to rotate synchronously in the same direction. When the threaded rod 6 rotates, it will drive the threaded block 7 attached to the side of the voltage-stabilized power supply body 1 to move upward synchronously through the support block 8, so as to make the voltage-stabilized power supply body 1 away from the ground. After the voltage-stabilized power supply body 1 is lifted, its bottom forms a vertical isolation zone with the ground, completely blocking the rising path of ground dust, metal debris and other particulate matter. The adjustable lifting height design allows the user to set a safe distance according to the ambient dust concentration. For example, in a textile workshop or metal processing plant, the risk of short circuit caused by fiber or chip accumulation can be avoided. The air gap formed after lifting can block the capillary rise of moisture from the ground, especially in basements or during the rainy season, effectively preventing the circuit board from being corroded by condensation.

[0033] After the lifting component 2 lifts the stabilized power supply body 1, the locking mechanism 9 automatically locks the stabilized power supply body 1. The working process is as follows: when the lifting component 2 rises, the block 20 will fit on the side wall of the connecting bracket 5. At this time, the spring 1 28 is in a compressed state. When the horizontal surface 22 of the block 20 is on the same horizontal line as the groove wall at the bottom of the slot 19, the spring 1 28 prompts the block 20 to pop out. The horizontal surface 22 of the block 20 and the slot 19 form a multi-directional self-locking. When the height of the stabilized power supply body 1 needs to be further raised, the block 20 will be pressed against the side wall of the connecting bracket 5. When the lifting assembly 2 continues to operate, the inclined surface B21 of the block 20 will gradually approach and squeeze into the slot 19 until it is out of the current slot 19. The spring 1 28 is compressed. When the horizontal surface 22 of the block 20 is on the same horizontal line as the wall at the bottom of the next slot 19, the spring 1 28 causes the block 20 to pop out again, thereby achieving the height increase while the voltage-stabilized power supply body 1 can be intermittently self-locked, ensuring that the power supply can be stably supported at different heights, thereby improving the stability, safety and adaptability of the equipment. Each slot 19 corresponds to a specific load range. The horizontal surface 22 of the block 20 and the bottom of the slot 19 are completely fitted to form a rigid support surface, distributing the weight of the power supply body to multiple support points, avoiding structural deformation caused by single-point overload. Even if the drive motor loses control or the threaded rod 6 breaks, the mechanical engagement between the block 20 and the slot 19 can still bear the entire weight of the power supply body, forming a physical anti-fall barrier.

[0034] The working process of the lifting component 2 lowering the voltage-stabilized power supply body 1 for inspection or other operations is as follows: continue to lift the voltage-stabilized power supply body 1 to the highest position through the lifting component 2. At this time, the block 20 will be attached to the side wall of the connecting bracket 5. When the inclined surface B21 of the block 20 gradually approaches and fits the inclined surface A16 of the retaining block 15, the retaining block 15 squeezes the block 20 to cause the movable block 23 to slide toward the side of the fixed plate 25, thereby causing the arc groove 31 to gradually approach the arc block 30. When the arc groove 31 and the arc block 30 are on the same horizontal line, the spring 2 34 causes the movable frame 29 to press down, and the arc block 30 is stuck in the arc groove 31, locking the movable block 23 in the through groove 18. At this time, the lifting component 2 can be lowered to a suitable height for inspection or other operations, realizing rapid unlocking and height adjustment of the equipment, facilitating operation, and improving the practicality of the equipment.
