By providing a heat dissipation groove 79, the high-temperature airflow in the explosion-proof cavity 15 is discharged through the heat dissipation groove 79.

[0056] The assembly component 8 includes two splicing grooves 81 and two splicing blocks 82. The two splicing grooves 81 are opened on one side of the switch cabinet body 1. The two splicing blocks 82 are fixedly installed on the side of the switch cabinet body 1 away from the splicing grooves 81. The middle parts of the two splicing blocks 82 are opened with limiting grooves 83. Two equipment sleeves 84 are fixedly installed on the side of the switch cabinet body 1 close to the splicing grooves 81. The interiors of the two equipment sleeves 84 are both slidably provided with limiting protrusions 85. One end of the two equipment sleeves 84 is threadedly installed with a threaded rod 88, and one end of the threaded rod 88 is rotatably connected to one end of the limiting protrusion 85.

[0057] By adopting the above technical solution, by setting the splicing groove 81 and the splicing block 82, when the splicing block 82 is horizontally plugged into the splicing groove 81, the two switch cabinet bodies 1 can be quickly assembled, and by setting the limiting groove 83 and the limiting protrusion 85, when the limiting protrusion 85 is horizontally inserted into the limiting groove 83, the limiting protrusion 85 limits and fixes the splicing block 82 through the limiting groove 83, so that the two switch cabinet bodies 1 are assembled together, and by rotating the threaded rod 88, the threaded rod 88 drives the limiting protrusion 85 to move horizontally.

The guide rods 87 pass through the fixing ears 86 and are slidably connected to the fixing ears 86. The other ends of the two threaded rods 88 are fixedly installed with rotating handles 89.

[0059] By adopting the above technical solution, by setting the fixing ear 86 and the guide rod 87, the guide rod 87 guides the limiting protrusion 85 in the horizontal direction through the fixing ear 86, so that the limiting protrusion 85 keeps moving in the horizontal direction, and the rotating handle 89 can be manually rotated to rotate the threaded rod 88.

[0060] Working principle: When the feed switch 2 needs to be installed in the flameproof chamber 15, the operator first places the feed switch 2 on two L-shaped support plates 51, and the two L-shaped support plates 51 support the feed switch 2 through two first protective pads 52;

[0061] Subsequently, the operator manually rotates the rotating disk 62, and the rotating disk 62 rotates the worm 6, and the worm 6 drives the worm wheel 61 to rotate, and the worm wheel 61 rotates the gear 59 through the rotating rod 58, and the gear 59 makes the two tooth plates 57 approach each other, and the two tooth plates 57 make the two groups of L-shaped limit plates 53 and the two groups of L-shaped baffles 55 approach each other through the two L-shaped connecting frames 571 and the two connecting plates 56, until the side walls of the two groups of second protective pads 54 are in close contact with the shell of the feed switch 2, and then the rotating disk 62 is stopped. At this time, the two groups of L-shaped limit plates 53 and the two groups of L-shaped baffles 55 limit the feed switch 2, so that the feed switch 2 is fixed in the flameproof chamber 15, thereby conveniently realizing the fixed installation of the feed switch 2, thereby effectively improving the convenience of installing the feed switch 2;

[0062] When it is necessary to dissipate heat for the module equipment in the flameproof cavity 15, the operator starts the air cooling unit 77. The cold air generated by the operation of the air cooling unit 77 enters the multiple first air inlet holes 71. Part of the cold air in the multiple first air inlet holes 71 enters the multiple vertical chambers 73 and the multiple horizontal chambers 75 through the connecting cavity 72. The cold air in the multiple vertical chambers 73 and the multiple horizontal chambers 75 enter the multiple flameproof cavities 15 through the multiple second air inlet holes 74 and the multiple third air inlet holes 76, so that the cold air contacts the module equipment in the multiple flameproof cavities 15 to achieve cooling and heat dissipation. At the same time, the high-temperature airflow in the flameproof cavity 15 is discharged through the multiple heat dissipation slots 79, so that the module equipment in the multiple flameproof cavities 15 is cooled and dissipated, thereby improving the operation efficiency and service life of the module equipment.

[0063] When it is necessary to assemble two switch cabinet bodies 1, the operator first aligns the two sides of the two switch cabinet bodies 1, the two splicing blocks 82 on one side of one switch cabinet body 1 correspond to the two splicing grooves 81 on the other side of the switch cabinet body 1, and then pushes one of the switch cabinet bodies 1 to make the two splicing blocks 82 horizontally inserted into the two splicing grooves 81. Subsequently, the operator manually rotates the two rotating handles 89, and the two rotating handles 89 rotate the two threaded rods 88. While the two threaded rods 88 rotate, the two limiting protrusions 85 are driven to move horizontally, so that the two limiting protrusions 85 move into the limiting grooves 83 on the two splicing blocks 82. At this time, the limiting protrusions 85 fix the splicing blocks 82 in the splicing grooves 81 through the limiting grooves 83, so that the two switch cabinet bodies 1 are in a fixed state, thereby conveniently realizing the rapid assembly of the switch cabinet bodies 1, thereby effectively improving the convenience of modular installation of the switch cabinet bodies 1, and reducing the operation time and operation cost of manual installation.
