[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-5 The present invention provides the following two preferred embodiments:

[0024] Example 1: A collision protection device for dry-type transformers, comprising: a protective box 1, wherein a dry-type transformer body 2 is fixedly installed inside the protective box 1, a door is provided at the front end of the protective box 1, a wiring port and a heat dissipation vent are provided on the back of the protective box 1, and spring dampers 3 are fixedly installed at equal intervals at the four corners of the top of the protective box 1, with the other end of the spring damper 3 being fixedly connected to a mounting plate 4; a protective plate 5, wherein a rubber pad 6 is fixedly laid on the upper end of the protective plate 5, and the protective plate 5 is installed on the protective box 1 through a mounting assembly and an auxiliary assembly; brackets 7 in the mounting assembly are fixedly installed at equal intervals at the bottom end of the protective plate 5, and the bottom end of the brackets 7 is fixed to a fixing plate 8. The connection includes a circular hole 9 on the fixing plate 8, and a boss 10 symmetrically fixedly mounted on the fixing plate 8. The fixing plate 8 is engaged with the mounting plate 4. A rotating rod 11 is rotatably mounted on the side wall of the boss 10. The fixing plate 8 has symmetrical slots 12 on both sides, and a wedge 13 is fixedly mounted in the slots 12. The rotating rod 11 is engaged with the slots 12 and abuts against the inclined surface of the wedge 13. The mounting plate 4 has symmetrical positioning slots 14 on both sides, which are engaged with the rotating rod 11. A guide post 15 is fixedly mounted on the protective box 1. The end of the guide post 15 is tapered and passes through the mounting plate 4. The guide post 15 is inserted into the fixing plate 8.

[0025] In use, lift the fixing plate 8 so that the round hole 9 is guided and inserted into the guide post 15 on the protective box 1, and then move it downward so that the fixing plate 8 is engaged with the mounting plate 4. During the process, the rotating rod 11 abuts against the inclined block 13 in the slot 12 under the action of gravity, ensuring that the rotating rod 11 is in an inclined state when the fixing plate 8 is installed. This prevents the rotating rod 11 from rotating if it comes into contact with the mounting plate 4 during the downward movement of the fixing plate 8, thus avoiding affecting the engagement between the fixing plate 8 and the mounting plate 4. After adjusting the position of the fixing plate 8, rotate the rotating rod 11 so that the rotating rod 11 is engaged in the slot 12 and the positioning slot 14, and then fix the position of the rotating rod 11. This completes the installation of the protective plate 5 on the protective box 1, thereby preventing the dry-type transformer body 2 from being damaged by falling objects. The spring damper 3 and the rubber pad 6 play a buffering role, improving the protection effect on the dry-type transformer body 2. The protective plate 5 can be easily installed and removed from the protective box 1 of the dry-type transformer body 2, making it easy to replace the protective plate 5 after it is damaged, and ensuring the protection effect against falling objects on the dry-type transformer.

[0026] Example 2: Based on Example 1, the fixing block 16 in the auxiliary component is symmetrically fixed at the bottom of the mounting plate 4. A plug post 17 is movably sleeved on the fixing block 16. A pull ring 18 is fixedly installed at the end of the plug post 17. A limit block 19 is fixedly sleeved on the plug post 17. A spring 20 is sleeved on the plug post 17. The two ends of the spring are respectively engaged with the fixing block 16 and the limit block 19. A positioning insertion hole 21 is opened on the side wall of the rotating rod 11. The plug post 17 is inserted into the positioning insertion hole 21.

[0027] In use, after the position of the fixing plate 8 is adjusted, pull the pull ring 18 to control the movement of the insertion post 17 and the limiting block 19, so that the limiting block 19 compresses the spring 20 until the rotating rod 11 is engaged in the slot 12 and the positioning slot 14. Then release the pull ring 18, the spring 20 returns to its original position and pushes the limiting block 19 to move, so that the insertion post 17 is engaged with the positioning insertion hole 21 to fix the position of the rotating rod 11, thereby realizing the fixed installation of the protective plate 5. The operation is simple and quick, and it is convenient to disassemble and replace the protective plate 5 after it is damaged.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
