[0033] When installing the device, the fixing frame 21 is first installed. After the fixing frame 21 is fixed on the ground, the outer shell 1 is then installed on the fixing frame 21 to fix the device. The fixing frame 21 is not only smaller in size than the outer shell 1, but also lighter in weight. During installation, it is easy for the staff to operate it so that it can be fixed flat on the ground. After the outer shell 1 is placed on it, the outer shell 1 can be kept flat. Then the first rotating shaft 3 is installed, and the impeller 4 on it can extend to one side of the outer shell 1, so that when it is used in an open area outdoors, the impeller 4 can be blown by the wind, thereby driving the heat dissipation fan 2 to rotate, thereby dissipating heat in the outer shell 1.

[0034] In order to fix the fixing frame 21 on the ground and ensure the stability of the device during use, the following technical scheme is provided: a positioning bolt 22 is provided inside the fixing frame 21, the positioning bolt 22 is inserted into the support leg 13, and the positioning bolt 22 and the support leg 13 are threadedly matched, and a positioning hole 23 is also opened on the fixing frame 21, an insert block 14 is fixedly connected to the lower end of the outer shell 1, and a positioning block 15 is fixedly connected to one side of the insert block 14, and the positioning block 15 can be inserted into the positioning hole 23. During installation, in order to ensure that the fixing frame 21 can be stably installed on the ground, the positioning bolt 22 can be inserted into the ground through the provided positioning bolt 22. In the outdoor environment, the ground is mostly soil, so the positioning bolt 22 can be inserted into the ground and ensure the stability of the device during use.

[0038] After the positioning bolt 22 is inserted into the ground, in order to further ensure the stability of the fixing frame 21, the following technical scheme is provided: the rotating block 27 is rotatably arranged in the positioning bolt 22, and when the rotating block 27 rotates, the rotating block 27 can drive the positioning bolt 22 to rotate together, so that the positioning bolt 22 can be inserted into the ground, and a horizontally movable extension portion 28 is also provided in the positioning bolt 22, and a vertical rod is fixed to the extension portion 28, and an arc groove 29 is provided on the lower end surface of the rotating block 27, and the vertical rod is inserted into the arc groove 29.

When the positioning bolt 22 needs to be slid downward, the rotating block 27 is rotated. At this time, the slider presses against the side wall of the slide groove, thereby driving the positioning bolt 22 to rotate. When the extension portion 28 needs to be pushed out, the rotating block 27 is rotated in the opposite direction. At this time, the slider slides in the slide groove, thereby allowing the extension portion 28 to slide.
