[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a wind power converter, including a shell 1, four support legs 2 fixedly installed at the bottom of the shell 1, a rain cover 3 set at the top of the shell 1, four guide columns 12 fixedly installed on the lower side of the rain cover 3, four guide columns 23 fixedly installed on the upper side of the shell 1, an electric telescopic rod 5 fixedly installed at the center of the inner bottom wall of the shell 1, an installation plate 6 fixedly installed at the movable end of the electric telescopic rod 5, baffles 7 fixedly installed on the four perimeters of the upper side of the installation plate 6, and a housing body 8 set on the upper side of the installation plate 6, the housing body 8 being set inside the area surrounded by the four baffles 7;

[0026] A protective cylinder 4 is fixedly installed on the inner bottom wall of the outer shell 1. The upper end of the protective cylinder 4 is open and is located on the outside of the electric telescopic rod 5. The protective cylinder 4 protects the electric telescopic rod 5 and prevents rainwater from corroding and damaging it. An opening 14 is provided on the upper side of the outer shell 1, and the area of ​​the opening 14 is larger than the area of ​​the mounting plate 6, so that the electric telescopic rod 5 can be activated to push the mounting plate 6 to the upper side of the outer shell 1 and then place the box body 8. An opening 2 15 is provided on the lower part of each of the four outer sides of the outer shell 1, and an opening 3 16 is provided on the four corners of the bottom side of the outer shell 1. The height of the opening 2 15 is lower than that of the mounting plate 6 to prevent rainwater from entering the mounting plate 6 and affecting the box body 8. The opening 3 16, the opening 2 15 and the opening 1 14 can all dissipate the heat generated by the box body 8, with high heat dissipation efficiency.

[0027] Each guide post 12 has a guide hole 17 on its bottom side. The upper end of each guide post 2 13 is inserted into the corresponding guide hole 17. Each guide post 12 and the corresponding guide post 2 13 have a through hole 19. A fixing bolt 18 is inserted into each through hole 19. One end of the fixing bolt 18 is threaded with a fixing nut 20. The outer shell 1 and the rain cover 3 are fixedly connected by the fixing bolt 18 and the fixing nut 20. The upper ends of the four outer surfaces of the outer shell 1 are all provided with threaded holes 21. A threaded rod 10 is inserted through each threaded hole 21. A turntable 9 is fixedly installed at one end of each threaded rod 10. A pushing block 11 is rotatably installed at the other end of each threaded rod 10. When the turntable 9 is rotated, the threaded rod 10 moves inward to the inner side of the outer shell 1, pushing the pushing block 11 to move. One end of the pushing block 11 presses against the side of the box body 8, further pressing and fixing the box body 8 placed on the mounting plate 6 to prevent it from shaking due to external impact. The fixing of the box body 8 has high stability.

[0028] Working principle: First, activate the electric telescopic rod 5 to push the mounting plate 6 through opening 14 to the upper side of the outer shell 1. Then, place the housing body 8 on the mounting plate 6, with the four baffles 7 acting as barriers. Activate the electric telescopic rod 5 again to retract the mounting plate 6 and housing body 8 back into the outer shell 1. Rotate each turntable 9 on the outer side of the outer shell 1, causing the threaded rod 10 to move inwards, pushing the push block 11 to press against the four sides of the housing body 8, thus securing the housing body 8. Then, insert the four guide posts 12 below the rain cover 3 into the corresponding guide posts 13, and use fixing bolts 18 and fixing nuts 20 to penetrate the through holes 19. The rain cover 3 is fixedly installed on the upper side of the outer shell 1. Openings 14, 15, and 16 have a large heat dissipation area, which can quickly dissipate the heat generated by the body 8. At the same time, the rain cover 3 above opening 14 provides rain protection. Since the height of the body 8 is higher than opening 2 15, rainwater falling from the sky cannot enter its interior. Some of the rainwater entering from opening 2 15 flows out to the outside of the outer shell 1 through opening 3 16. The protective cylinder 4 protects the electric telescopic rod 5 and prevents rainwater from entering. Overall, the body 8 is in a relatively stable environment, and external rainwater cannot invade it. It also has excellent heat dissipation capabilities.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
