The front side of the vertical conveying shell 26 is fixed to a connecting pipe 29, and the front end of the connecting pipe 29 is fixedly connected to the quartz sand tank 30, so that the quartz sand flows inside the transparent cover 6 through the conveying mechanism.

[0056] like Figure 1 In the embodiment, the bottom end of the first vertical pipe 24 is connected to the top end of the transverse transport shell 25 , so that the quartz sand flows from the first vertical pipe 24 to the transverse transport shell 25 .

[0057] like Figure 1 and Figure 6 In the figure, the moving mechanism includes a fifth motor 38, a roller shaft 39, a support rod 40, a connecting block 41, a limiting rod 42, a mounting plate 43 and a mounting frame 44. The fifth motor 38 is installed on the top of the positioning plate 37, and the output end of the fifth motor 38 is connected to the roller shaft 39. The support rod 40 is fixed to the outer side of the roller shaft 39. The end of the support rod 40 is rotatably connected to the connecting block 41.

[0059] like Figure 1 In the embodiment, the bottom plate 45 is a porous structure, and a flow channel is formed between the bottom plate 45 and the transparent cover 6, so that the quartz sand can pass through the bottom plate 45;

[0060] The outer shell 2, the inner shell 3, the cabinet door 5, the transparent cover 6 and the transparent door 7 are all made of insulating materials. When using the solid insulation cabinet for easy observation, the electrical components are installed on the mounting frame 44, and the transparent door 7 and the cabinet door 5 are closed;

[0061] Silicone oil is stored in the storage tank 18. The temperature of the silicone oil is lowered by the refrigeration sheet 19. The pumping pump 15 is turned on. Under the action of the pumping pump 15, the low-temperature silicone oil in the storage tank 18 flows from the first delivery pipe 16 to the second delivery pipe 17, and then flows into the cavity 4 formed by the outer shell 2 and the inner shell 3. The silicone oil in the cavity 4 exchanges heat with the heat generated by the electrical components.

[0063] The transparent cover 6 and the transparent door 7 are provided with quartz sand inside, and the quartz sand is used to enhance the insulation effect. When the electrical components need to be repaired, the first baffle 23 is moved backward under the action of the first electric telescopic rod 22, so that the first baffle 23 leaves the first vertical tube 24, and the quartz sand in the transparent cover 6 and the transparent door 7 flows to the first vertical tube 24 through the holes of the guide plate 21 and the bottom plate 45, and flows from the first vertical tube 24 to the horizontal conveying shell 25, and the third motor 27 is turned on, and the third motor 27 drives the screw 28 to rotate, and the third motor 27 drives the screw 28 to rotate. The quartz sand is transported to the connecting pipe 29 through the rotation of the two sets of screws 28 in the horizontal and vertical directions, and flows to the quartz sand tank 30 through the connecting pipe 29. The quartz sand tank 30 is temporarily stored in the connecting pipe 29, the cabinet door 5 and the transparent door 7 are opened, and then the fifth motor 38 is turned on. The fifth motor 38 drives the roller 39 to rotate forward. The rotation of the roller 39 pushes the connecting block 41, the mounting plate 43 and the mounting frame 44 to move forward, which is convenient for the staff to repair the electrical components on the mounting frame 44. The moving track of the mounting plate 43 is limited by the limiting rod 42;

[0064] When it is necessary to transport quartz sand to the inside of the transparent cover 6 and the transparent door 7 again, the second electric telescopic rod 33 is opened, and the second electric telescopic rod 33 drives the second baffle 32 to move rightward, and the quartz sand in the quartz sand tank 30 flows to the inside of the transparent cover 6 and the transparent door 7 through the second straight pipe 31, and the fourth motor 35 is turned on, and the fourth motor 35 drives the inclined plate 36 to rotate, and the rotation of the inclined plate 36 makes the quartz sand evenly fall on the inside of the transparent cover 6 and the transparent door 7;
