[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use: 1. A sub-frame combination mechanism is provided. Through the cooperation of the combination bottom plate, combination top cover, vertical rod, screw rod, worm gear, rotating cylinder, traction rod, splicing plate and clamping frame, it is convenient to divide the U-shaped iron core into two groups of frames, realizing modular splicing. At the same time, the U-shaped iron core is installed separately, and the U-shaped iron cores with different thicknesses can be clamped and adjusted according to needs, improving adaptability. Then, through the cooperation of the positioning cylinder and the positioning screw rod, it is convenient to combine and splice the two U-shaped iron core frames together, and when splicing, the coil is positioned and installed between the U-shaped iron cores, simplifying the installation steps of the U-shaped iron core and the coil, and at the same time facilitating the disassembly of the U-shaped iron core and the coil, improving the convenience of maintenance and replacement; Through the cooperation of the U-shaped frame, insertion rods, jacks, and anti-offset plates, the splicing frame and the clamping frame are limited, thus ensuring the alignment effect of the two U-shaped iron core frames, preventing the phenomena of offset and dislocation, enabling the two U-shaped iron cores to fit tightly together to form a complete annular U-shaped iron core, reducing damage. Additionally, through the cooperation of the rotating shaft sleeve, lifting plate, buckling plate, traction plate, and support plate, the U-shaped iron cores and coils of different sizes are limited and fixed, further improving the stability of the U-shaped iron cores and coils. Furthermore, during assembly, the shaking is reduced, and the phenomenon of collision damage is prevented.

[0015] 2. A heat dissipation and energy-saving adjustment mechanism is provided. Through the cooperation of the heat exchange cylinder, heat dissipation fins, and heat dissipation cylinder, the heat inside the transformer is transferred to the inside of the heat exchange cylinder to heat the water-based coolant, causing it to expand due to heat and enter the inside of the heat dissipation cylinder. Then, through the cooperation of the heat dissipation fins, the temperature inside the transformer is reduced; Through the cooperation of the gantry, piston plate, sliding rod, top plate, collar, cushion plate, and touch switch, when the water-based coolant continues to be heated and its volume continues to expand, it pushes the piston plate and the sliding rod upward to contact the touch switch, starting the fan, facilitating the air to enter the inside of the heat dissipation fins through the air inlet channel, improving the heat exchange efficiency, and enhancing the heat dissipation effect; As the water-based coolant continues to expand, it pushes the cushion plate upward to contact the touch switch on the gantry, starting the water pump. Through the cooperation of the water suction pipe, horizontal pipe, spray pipe, water receiving box, and return pipe, cyclic spraying is carried out to wet the heat dissipation fins, and in cooperation with the fan, the evaporation efficiency of the water is improved, quickly taking away the heat, further enhancing the heat dissipation intensity, rapidly reducing the temperature inside the transformer, thereby reducing the heat absorbed by the water-based coolant, facilitating the reset of the piston plate and the cushion plate, releasing the contact with the touch switch, turning off the fan and the water pump, and adjusting the heat dissipation intensity in real time as needed, reducing energy consumption while ensuring the heat dissipation effect.

[0016] In summary, through the sub-frame combination mechanism, modularization is achieved, facilitating the division of the U-shaped iron core into two groups. After separate clamping and installation, splicing is carried out, improving the convenience of disassembly and assembly, facilitating subsequent maintenance and replacement, increasing the service life, and using the heat dissipation and energy-saving adjustment mechanism to adaptively adjust the heat dissipation method and intensity according to the heat inside the transformer, saving energy and reducing costs.

[0022] The working principle and use process of the present invention are as follows: first, two groups of U-shaped iron cores 312 are placed inside the combined bottom plate 302 and the combined top cover 305 respectively, and then the vertical rod 314 is rotated to drive the worm 315 to rotate, and through the cooperation and transmission of the worm wheel 316, the rotating drum 308 is pushed to rotate, and the traction rod 309 is pulled to move, and through the cooperation of the splicing plate 310, the clamping frame 311 slides on the fixed plate 306, and the U-shaped iron cores 312 of different thicknesses are clamped and fixed as needed, thereby improving the stability of the U-shaped iron core 312 on the combined bottom plate 302 and the combined top cover 305, and the U-shaped frame 320 on the clamping frame 311 is used to further limit the U-shaped iron core 312 to prevent it from tipping over; Next, the clamping frame 311 moves, driving the limiting slide plate 322 to slide along the limiting groove 321, and driving the bracket 323, the screw rod 324, the lifting plate 325 and the pinch plate 326 to slide, forcing the pinch plate 326 to be inserted into the U-shaped core 312, and at the same time, the rotating sleeve 329 is rotated to slide with the lifting plate 325 and the pinch plate 326, so that the pinch plate 326 moves and fits closely with the inner wall of the U-shaped core 312, thereby limiting the position of the U-shaped core 312, further improving the stability of the U-shaped core 312 in the clamping frame 311 and reducing shaking; Next, put the coil 313 on the U-shaped iron core 312. Then, reverse the combined top cover 305 and align it with the combined bottom plate 302. Insert the positioning screw rod 304 into the positioning cylinder 303. At the same time, rotate the positioning screw rod 304 to move along the positioning cylinder 303, thereby driving the combined top cover 305 and the U-shaped iron core 312 to descend, forcing the two U-shaped iron cores 312 to align and join together to form a complete transformer iron core. At the same time, insert the insertion rod 317 into the insertion hole 318, and insert the anti-offset plate 319 into the groove to limit the splicing frame 307 and the clamping frame 311, ensuring the alignment effect, preventing deviation, and improving the alignment effect of the two U-shaped iron cores 312; Subsequently, rotate the rotating shaft sleeve 329 to drive the traction plate 327 and the support plate 328 to move, clamp and limit the coil 313, and use the buckle plate 326 to improve the limiting effect to prevent the coil 313 from shaking and ensure stability. When disassembling, reverse-rotate the positioning screw rod 304 to separate the combined top cover 305 and the combined bottom plate 302, thereby facilitating the subsequent removal of the coil 313 and the U-shaped iron core 312, improving the convenience of replacement, and facilitating maintenance and upgrading; Next, when the transformer is working, the heat generated inside is transferred to the inside of the heat exchange cylinder 402 through the action of the heat sink 404, causing the water-based coolant therein to expand due to heat. It rises along the heat exchange cylinder 402 into the heat dissipation cylinder 403, and then uses the heat sink 404 on the outside of the heat dissipation cylinder 403 to dissipate heat. After the temperature drops, it shrinks and falls back into the heat exchange cylinder 402. When the temperature inside the transformer is relatively high and the water-based coolant in the heat dissipation cylinder 403 cannot quickly discharge the heat and continues to rise, it pushes the piston plate 408, the sliding rod 407, and the top plate 414 to rise, contact the touch switch 413 on the cushion plate 412, start the fan 415, generate wind force, and send the outside wind into the heat dissipation fins 422 through the air inlet channel 426, improving the heat dissipation efficiency, reducing the temperature inside the transformer, reducing the heat absorbed by the water-based coolant, and causing it to shrink and fall back into the heat exchange cylinder 402; When the temperature of the water-based coolant still cannot drop, the temperature continues to rise and the volume continues to expand, it continuously pushes the sliding rod 407, the piston plate 408, the top plate 414, and the cushion plate 412 to rise, contact the touch switch 413 on the gantry 405, start the water pump 419, send the water in the water storage tank 417 into the horizontal pipe 420 through the water suction pipe 418, and spray it out through the spray pipe 421, so that the water wets the heat dissipation fins 422 and cooperates with the fan 415 to quickly evaporate the water to take away a large amount of heat, further improving the heat dissipation effect and efficiently reducing the temperature inside the transformer. The water that has not evaporated falls into the water receiving box 424 and is sent back into the water storage tank 417 through the return pipe 425 for convenient circulation; Finally, after the temperature inside the transformer decreases, with the cooperation of the tension spring 411, the sliding rod 407 and the piston plate 408 are pushed to reset, the contact with the touch switch 413 is released, the fan 415 and the water pump 419 are turned off, reducing energy consumption and improving convenience. Additionally, the rotating push rod 409 pushes the collar 410 to move, adjusting the distance between the collar 410 and the piston plate 408, and adjusting the elastic force of the tension spring 411 as needed.
