When the fixing hole 320 is separated from the fixing plate 314, the personnel can move the connecting pipe 301 to drive the winding coil 8 to be removed from the support plate 2, and then the personnel can inspect the winding coil 8. When the inspection is completed, Then move the connecting pipe 301 and put it between the two supporting plates 2. When the fixing plate 314 is aligned with the fixing hole 320, the turntable 309 is rotated in the opposite direction with the help of the anti-slip sleeve 310. The turntable 309 drives the screw rod 306, and the screw rod 306 drives the adjusting plate 307, so that the adjusting plate 307 drives the top plate 308 to move in the direction close to the fixing plate 314. In this process, the top plate 308 will use its oblique waist side to squeeze the oblique waist side of the fixing plate 314. At the same time, the fixing plate 314 will drive the positioning plate 313 along the inner wall of the positioning hole 312 during the squeezing of the top plate 308. When the fixing plate 314 is inserted into the inner wall of the fixing hole 320, the installation of the connecting tube 301 and the winding coil 8 can be completed. By setting the support rod 303 to a nickel-chromium alloy rod, the nickel-chromium alloy has excellent high temperature resistance and stable resistance value. The nickel-chromium alloy can remain stable at high temperatures and is suitable for various heating and heat dissipation applications. In the process of the screw rod 306 driving the adjustment plate 307 to move, the guide rod 311 can guide and position the adjustment plate 307, thereby preventing the adjustment plate 307 from rotating and offsetting during the movement of the top plate 308.

[0056] 2. In the present invention, when the cooling fan 325 is needed to assist the winding coil 8 in cooling, the driving motor 332 is first started to drive the driving gear 333 to rotate, the driving gear 333 drives the driven gear 331 to rotate, and the driven gear 331 drives the threaded rod 321 to rotate. At the same time, one of the threaded rods 321 will control the other threaded rod 321 to rotate synchronously with the reel 329 and the belt 330. During the rotation of the threaded rod 321, the adjusting frame 322 will be driven to move, and the adjusting frame 322 will drive the cooling fan 325. Then, the height of the cooling fan 325 can be adjusted. At the same time, the personnel needs to start the servo motor 326 to drive the gear block 327 to rotate. The gear block 327 will drive the adjustment block 324 with the help of the rack 328, so that the adjustment block 324 moves along the inner wall of the adjustment hole 323. At the same time, the adjustment block 324 will drive the cooling fan 325, so that the cooling fan 325 moves horizontally to blow air and dissipate heat to the winding coil 8. The vertical and horizontal movements of the cooling fan 325 are carried out synchronously, which can expand the blowing area of ​​the cooling fan 325, thereby increasing the heat dissipation area.

[0057] 3. In the present invention, when it is necessary to open the sealing plate to operate the parts inside the mounting hole 304, first rotate the nut 408 to move along the arc surface of the bolt 407, so that the nut 408 drives the rubber pad 409 to separate from the bolt 407. When the nut 408 and the rubber pad 409 are separated from the bolt 407, the coil spring 410 can drive the sealing cover 404 to quickly move in the direction away from the mounting hole 304, thereby achieving the effect of being able to quickly open the sealing cover 404. When the sealing cover 404 is opened, the personnel can operate the parts inside the mounting hole 304. When the operation is completed and the mounting hole 304 needs to be covered, first rotate the sealing cover 404 in the direction close to the mounting hole 304, and the sealing cover 404 drives the welding plate 403 and the rotating shaft 402, so that the rotating shaft 402 rotates along the inner wall of the fixing seat 401. When the bolt 407 passes through the auxiliary hole 411 on the rectangular plate 406 and the sealing cover 404 abuts against the outer wall of the connecting pipe 301, the nut 408 is put on the arc surface of the bolt 407, and finally the nut 408 is rotated to drive the rubber pad 409 to abut against the rectangular plate 406, and the personnel can complete the limiting of the sealing cover 404, wherein the rubber pad 409 can increase the friction force of the nut 408 close to the side of the rectangular plate 406, so that the nut 408 can be firmly abutted against the rectangular plate 406 with the help of the rubber pad 409. In addition, after the nut 408 is rotated to separate from the bolt 407, the coil spring 410 can drive the sealing cover 404 to move quickly in the direction away from the mounting hole 304, so as to achieve the effect of being able to quickly open the sealing cover 404.

[0058] 4. In the present invention, when it is necessary to adjust the protective plate 53 so that the protective plate 53 can protect the cooling fan 325 in rainy and snowy weather, first rotate the adjustment ring 56 to separate it from the rotating seat 51, and then rotate the protective plate 53. The protective plate 53 drives the rotating plate 52 to rotate along the inner wall of the rotating seat 51. During the rotation of the rotating plate 52, the sliding rod 55 is driven to slide along the inner wall of the sliding hole 54. When the protective plate 53 is rotated to the top of the cooling fan 325, the adjustment ring 56 is rotated to abut against the rotating seat 51, so that the protective plate 53 can be fixed.
