When it is necessary to inspect the position of the dry-type transformer body 3 that is obstructed by the door panels 6, the positioner releases the positioning of the door panels 6, and the operator drives the door panels 6 to move relative to the side panel 5 so that the side panel 5 is no longer located on one side of the dry-type transformer body 3. When it is necessary to inspect the position of the dry-type transformer body 3 that is obstructed by the side panel 5, the operator drives the two door panels 6 located on the side panel 5 to move, and the storage unit aligns the door panels with the door panels 6. The plate 6 is stored away. The operator adjusts the structure to move the side plate 5 and the door plate 6 horizontally relative to the base 1, so that the side plate 5 and the door plate 6 no longer block the position that needs to be inspected. As needed, the positions around the dry-type transformer body 3 that were originally blocked can be exposed to facilitate the inspection of the dry-type transformer body 3. The outer shell itself is designed as a modular, independently movable component, so that the localization of the inspection is matched with the localization of the opening of the outer shell. The entire side plate 5 and the door plate 6 attached to it can be moved as a whole, thereby creating a larger inspection window and realizing the inspection of different positions of the dry-type transformer body 3.

[0023] Example 2, based on Example 1, is... Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 9The horizontal adjustment structure includes a movable seat 7 fixedly installed at the bottom of the side plate 5, and the movable seat 7 is located below the platform 2. A locking unit that cooperates with the platform 2 is installed on the movable seat 7. A movable column 8 is fixedly connected to the top of the movable seat 7. A guide seat 9 is fixedly connected to the bottom of the platform 2. A first annular groove 10 that cooperates with the movable column 8 is opened at the bottom of the guide seat 9.

The top of the second movable plate 22 and the bottom of the movable base 7 are connected by a plurality of tension springs 24. A plurality of rollers 25 are fixedly connected to the bottom of the movable base 7. When the operator drives the two door panels 6 located on the side panel 5 to move and stores the door panels 6 through the storage unit, the operator drives the first movable plate 19 to move downwards. The first movable plate 19 drives the connecting column 23 and the second movable plate 22 to move downwards. The tension spring 24 is in a stretched state, so that the positioning column 20 disengages from the corresponding positioning hole 21, releasing the positioning of the movable seat 7. The operator drives the movable seat 7 and the movable column 8 to move. The movable column 8 slides from the clearance groove 11 into the first annular groove 10, and the movable seat 7 drives the side panel 5 to no longer contact the side of the platform 2, so that the side panel 5... The movable seat 7 can rotate relative to the platform 2, and the movable seat 7 drives the connecting block 16 and the anti-detachment block 18 to slide relative to the first slide groove 15. Then, the operator drives the movable seat 7 and the support seat 12 to rotate relative to the platform 2. The movable seat 7 drives the guide block 13 to slide in the second annular groove 14 through the support seat 12, and the movable column 8 slides in the first annular groove 10.

The top and bottom of the door panel 6 are provided with second sliding grooves 27, and limiting posts 28 are slidably installed within the second sliding grooves 27. The limiting posts 28 are located on the side of the two side panels 5 that are far apart, and the limiting posts 28 are fixedly connected to the corresponding support parts 26. The side panels 5 have clearance holes 29 that cooperate with the first movable plate 19. The first movable plate 19 passes through the corresponding clearance holes 29. The top of the first movable plate 19 is fixedly connected to a stop block 30 that cooperates with the door panel 6. The positioning device includes four hydraulic telescopic rods 31 fixedly installed on the top of the cover plate 4. The telescopic ends of the hydraulic telescopic rods 31 are fixedly connected to mounting plates 32. The cover plate 4 has four... Insert plate 33, the top of insert plate 33 has a groove 34, a slide plate 35 is slidably installed in the groove 34, the top of slide plate 35 is fixedly connected to the bottom of the corresponding mounting plate 32, the bottom of slide plate 35 is connected to the bottom of the inner wall of groove 34 by several compression springs 36, the bottom end of insert plate 33 is located in the corresponding second slide groove 27, and the bottom end of insert plate 33 has an inclined surface that cooperates with door panel 6. Limit grooves 37 are respectively opened on the inner walls of both sides of groove 34, and limit blocks 38 are slidably installed in the limit grooves 37, and limit blocks 38 are fixedly connected to slide plate 35. The cover plate 4 has an air outlet, and a cooling fan 39 is fixedly connected to the air outlet. The side plate 5 has an air inlet, and a filter screen 40 is fixedly connected to the air inlet. When the door panel 6 needs to be stored, the hydraulic telescopic rod 31 drives the mounting plate 32 and the sliding plate 35 to move upward. The sliding plate 35 drives the bottom end of the insert plate 33 to be pulled out from the corresponding second sliding groove 27 through the limiting block 38, releasing the restriction on the position of the door panel 6. The operator drives the door panel 6 to slide relative to the side plate 5 so that the side plate 5 no longer obstructs the position of the dry-type transformer body 3 that needs to be inspected, and the second sliding groove 27 on the door panel 6 slides relative to the limiting post 28 until the door panel 6 slides to the side of the side plate 5 away from the dry-type transformer body 3. The operator then drives... The first movable plate 19 and the second movable plate 22 move downwards. The first movable plate 19 drives the stop block 30 to move downwards, preventing the stop block 30 from supporting the rotation of the door panel 6. The tension spring 24 is in a stretched state. Then, the operator drives the door panel 6 to rotate relative to the limit post 28 and the support part 26 so that the two adjacent door panels 6 are parallel to the side panel 5. Then, the first movable plate 19 is released, and the tension spring 24 drives the second movable plate 22 and the first movable plate 19 to move upwards, so that the stop block 30 moves to the side of the door panel 6 away from the side panel 5. The position of the limit door panel 6 is set so that the two adjacent door panels 6 and side panels 5 remain stationary. When it is necessary to cover the dry-type transformer body 3 again through the door panel 6, the mounting plate 32 and the insert plate 33 are driven to descend to the initial height by the hydraulic telescopic rod 31. When the door panel 6 slides relative to the side panel 5, during the process of the door panel 6 moving to the initial position, the end of the door panel 6 contacts the inclined surface on the insert plate 33. As the door panel 6 continues to move, the door panel 6 pushes the insert plate 33 to move upward relative to the slide plate 35, and the compression spring 36 is in a compressed state. When the door panel 6 is dragged to move the insert plate 33 above the second slide groove 27, the door panel 6 returns to its initial position. The compression spring 36 drives the insert plate 33 to move downward relative to the slide plate 35 so that the bottom end of the insert plate 33 is inserted into the second slide groove 27, thus fixing the position of the door panel 6 and preventing the door panel 6 from shaking horizontally. The cooling fan 39 is activated, and the outside air enters the protective chamber composed of the platform 2, cover plate 4, side plate 5 and door panel 6 after being filtered by the filter screen 40. The hot air inside the protective chamber is discharged through the cooling fan 39.
