Description

Technical Field

[0002] In the power transmission system, the transformer box is a key device to ensure stable power transmission. Its protection performance and installation flexibility directly affect the reliability of power supply.

[0003] However, in the actual application of existing equipment, the traditional transformer box has a single protective structure. When facing external impacts and foreign object impacts, it lacks a buffer mechanism and multi-layer protection design, making it difficult to effectively resist impact energy, which can easily cause damage to the internal transformer and thus affect the normal operation of the power system. In the installation scenario, the lifting and adjustment function of the existing transformer box has defects, or the control is difficult due to the complex transmission structure, or it is impossible to achieve synchronous lifting of multiple components, making the installation process cumbersome and inefficient. It is difficult to adapt to the diverse requirements of transformer installation height in different environments, which is not conducive to actual application and operation.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The protective structure of the present invention can initially resist external impacts and protect the internal transformer through the linkage of the slider, the connecting rod, and the protective frame, in conjunction with the buffering of the first spring; the lifting structure realizes the synchronous rotation of the threaded column through multiple sets of bevel gear transmission, accurately controls the lifting and lowering of the transformer, and meets the requirements of different installation heights. Through the cooperation of the L rod, the second spring, the third spring and the limit block, a double buffer structure is formed. Not only does it enhance the protective frame's ability to absorb impacts, but it can also continue to provide protection for the transformer through spring reset after the impact, improving the device's impact resistance. The engagement of the first bevel gear and the second bevel gear realizes the lateral transmission of the threaded column's rotating power, making the transmission between multiple threaded columns more coordinated. The first fixed plate fixes the first rotating shaft to ensure transmission stability, ensure the synchronous operation of the threaded column during the lifting process, and avoid tilting of the mounting seat.

[0016] (2) The present invention constructs a multi-axis linkage transmission system through the meshing of the third bevel gear and the fourth bevel gear. The second fixed plate fixes the second rotating shaft to make the power transmission more stable, ensure the coordinated work of various components in the entire lifting structure, and improve the synchronization and reliability of the transformer lifting. The servo motor serves as the power core and accurately controls the rotation of the threaded column through the bevel gear transmission to realize the automated operation of the transformer lifting. The third fixed plate stabilizes the servo motor to avoid shaking during operation, ensure stable power output, and improve the control accuracy and working reliability of the lifting structure. The first and second protective rods increase the strength and density of the protective structure, which can not only resist the impact of small foreign objects, but also disperse the force of large impacts, thereby improving the overall impact resistance of the protective structure and providing more comprehensive protection for the transformer.

[0034] Working principle:

[0035] During use, the slide rods in the slide grooves on both sides of the protective box provide sliding tracks for the sliders. When an external impact occurs, the sliders slide along the slide rods and compress the first spring. At the same time, the sliders push the protective frame to expand through the connecting rod, forming an external protection for the protective box. The servo motor drives the sixth bevel gear to rotate, which drives the second rotating shaft to rotate through the fifth bevel gear. The fourth bevel gear then engages with the third bevel gear to rotate the first rotating shaft. Finally, the second bevel gear cooperates with the first bevel gear to rotate the threaded column, and the mounting seat rises and falls along the threaded column to achieve transformer height adjustment. When the protective frame is impacted, the L-rod slides into the connecting tube, and the first limit block compresses the second spring. At the same time, the second limit block at the end of the L-rod squeezes the third spring inside the connecting tube. The second and third springs of the double spring are compressed to absorb the impact energy. When the threaded column rotates, the first bevel gear on the outside rotates synchronously, meshing with the second bevel gears at both ends of the first rotating shaft, driving the first rotating shaft to rotate. The first fixed plate provides stable support for the first rotating shaft, ensuring that the shaft's position is fixed during transmission. The second rotating shaft rotates with the support of the second fixed plate. The fourth bevel gears at both ends of the second bevel gear mesh with the third bevel gear on the first rotating shaft, transmitting the power of the first rotating shaft to the second rotating shaft, achieving power connection between different shafts. After the servo motor is started, the output shaft drives the sixth bevel gear to rotate and mesh with the fifth bevel gear on the second rotating shaft, providing a power source for the entire lifting structure, driving the second rotating shaft and subsequent transmission components to operate. The third fixed plate fixes the servo motor to ensure the stability of the motor during operation. The first protective rod on the inner wall of the protective frame and the second protective rod between the connecting pipes are arranged at a fixed distance to form a multi-layer protective barrier. When an external object hits the protective frame, the protective rod disperses the impact force and reduces the local force intensity.
