[0026] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0027] The present utility model provides a transformer protection structure as shown in Figures 1-5 Figure, including an underframe 1 for placing the transformer body 2;

[0028] A protective frame 3 is installed around the underframe 1 for protection. The transformer body 2 is installed inside the upper part of the underframe 1. A first movable frame 11 is installed at the rear of the protective frame 3. A second movable frame 13 is fixedly installed above the underframe 1. A frame 14 is arranged above the protective frame 3. Snap rings 15 are fixedly connected around the frame 14. Bolts 16 penetrate through the inside of the snap rings 15. An anti-fall net 17 is arranged inside the frame 14;

[0029] A support and reinforcement assembly 12 is installed between the first movable frame 11 and the second movable frame 13 for strengthening the stability of the protective frame 3. It is installed inside the protective frame 3 through the first movable frame 11. Then, according to the installation and support angle of the protective frame 3, the rotating hand 1202 is rotated to drive the first gear 1203 to mesh with the second gear 1204 for transmission, so that the lead screw 1205 rotates to drive the external telescopic rod 1206 to perform telescopic adjustment. After adjusting to a suitable support angle, the other end of the second movable frame 13 is installed on the underframe 1. Through the setting of the support and reinforcement assembly 12, an inclined support force is formed, strengthening the strength and stability of the protective frame 3 and improving the protection effect.

[0030] As shown in Figure 1 and Figure 2As shown in the figure, a sleeve rod 4 is arranged inside the rear of the protective frame 3. A plug rod 5 is movably connected inside the sleeve rod 4. A handle 6 is fixedly installed on the outside of the plug rod 5. A spring 7 is arranged above the handle 6 and on the outside of the plug rod 5. Installation grooves 8 are formed on the upper and lower surfaces on one side of the protective frame 3. Installation blocks 9 are fixedly installed on the upper and lower parts on the other side of the protective frame 3. Limit grooves 10 are formed on the upper and lower surfaces of the installation blocks 9. By pulling the handle 6 at the rear of the protective frame 3, the upper and lower groups of plug rods 5 are telescoped into the sleeve rod 4. Then, the installation block 9 on one side of the other protective frame 3 is inserted into the installation groove 8. At this time, the handle 6 is released, and by using the resilience of the spring 7 on the outside of the plug rod 5, the plug rod 5 rebounds and is inserted into the limit groove 10 in the installation block 9 for limit fixation, so that the two protective frames 3 are spliced. This splicing method is simple and convenient, and at the same time, the limiting method also improves the stability and firmness between the two protective frames 3.

[0031] As Figure 2 shown, the plug rod 5 is movably connected with the sleeve rod 4, the plug rod 5 is movably clamped with the limit groove 10 on the installation block 9, and the plug rod 5 rebounds and is inserted into the limit groove 10 in the installation block 9 through the spring 7, thereby strengthening the connection firmness between the two protective frames 3.

[0032] As Figure 2 shown, the installation groove 8 formed on the surface of one side of the protective frame 3 is movably clamped with the installation block 9 on the other side of the protective frame 3. The installation groove 8 and the installation block 9 are used in cooperation, and the installation block 9 is inserted into the installation groove 8 on one side of the other protective frame 3, thereby strengthening the limit stability of the splicing therebetween.

[0033] As Figure 3 and Figure 4 shown, the support and reinforcement assembly 12 includes a telescopic sleeve 1201, a turning handle 1202, a first gear 1203, a second gear 1204, a lead screw 1205, a telescopic rod 1206, and a second movable frame 13. The telescopic sleeve 1201 is installed on one side of the second movable frame 13. A turning handle 1202 is arranged on one side of the telescopic sleeve 1201. A first gear 1203 is fixedly installed at one end of the turning handle 1202. A second gear 1204 is movably connected to one side of the first gear 1203. A lead screw 1205 is fixedly installed inside the second gear 1204. The telescopic rod 1206 is movably connected to the outside of the lead screw 1205. By rotating the turning handle 1202 to drive the first gear 1203 to rotate, and using the meshing transmission of the rotation of the first gear 1203 and the second gear 1204, the internal lead screw 1205 rotates to push the telescopic rod 1206 to telescopically move inside the telescopic sleeve 1201, realizing the installation of the support angle.

[0034] As Figure 4As shown, the telescopic rod 1206 is rotatably connected to the lead screw 1205, and the telescopic rod 1206 is movably connected to the telescopic sleeve 1201. During the rotation of the lead screw 1205, the external telescopic rod 1206 is driven to telescopically move within the telescopic sleeve 1201, thereby forming the support angle between the protective frame 3 and the chassis 1 and strengthening the stability of the overall protective frame 3.

[0035] The working principle of this utility model is as follows: First, according to the protected range outside the transformer body 2, multiple groups of protective frames 3 are spliced. By pulling the handle 6 at the rear of the protective frame 3, the insertion rods 5 of the upper and lower groups are telescoped into the sleeve rods 4. Then, the mounting block 9 on one side of another group of protective frames 3 is inserted into the mounting groove 8. At this time, when the handle 6 is released, by the resilience of the spring 7 outside the insertion rod 5, the insertion rod 5 rebounds and is inserted into the limiting groove 10 in the mounting block 9 for limiting and fixing, so that the splicing of the two groups of protective frames 3 is completed. After that, multiple groups of protective frames 3 are installed above the chassis 1 and around the transformer body 2. Then, the first movable frame 11 is installed inside the protective frame 3. Then, according to the installation and support angle of the protective frame 3, the rotating handle 1202 is rotated to drive the first gear 1203 to mesh and drive with the second gear 1204, so that the lead screw 1205 rotates to drive the external telescopic rod 1206 to perform telescopic adjustment within the telescopic sleeve 1201. After adjusting to the appropriate support angle, the second movable frame 13 at the other end is installed on the chassis 1. Through the setting of the entire support and reinforcement assembly 12, an inclined support force is formed, strengthening the strength and stability of the protective frame 3 and improving the protection effect. Then, the frame 14 and the anti-falling net 17 are sleeved above the protective frame 3, and are installed by using bolts 16 to penetrate through the snap rings 15 and the upper end of the protective frame 3. The anti-falling net 17 can prevent sundries from falling onto the outer surface of the transformer body 2, improving the safety of the transformer body 2 during use. Just like this, the use process of this transformer protection structure is completed.
