Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] As Figures 1 - 5 shown, it relates to a safety explosion-proof electrical cabinet, including an explosion-proof electrical cabinet body 1. A cabinet door 2 is hinged to the outer wall of the explosion-proof electrical cabinet body 1. Multiple explosion-proof electrical conduits 3 are fixedly interconnected at the bottom of the explosion-proof electrical cabinet body 1. The multiple explosion-proof electrical conduits 3 are mainly used for wiring and are sealed to isolate flammable gases and dust.

[0024] A threaded docking sleeve 4 is fixedly connected to the top of the explosion-proof electrical cabinet body 1. A round sleeve 5 is threadedly connected to the inner wall of the threaded docking sleeve 4. The round sleeve 5 rotates through the threaded docking sleeve 4 to disassemble the round sleeve 5 from the overall pressure relief mechanism. Two stainless steel pressure relief nets 6 are fixedly inlaid on the outer wall of the round sleeve 5. The stainless steel pressure relief nets 6 have good corrosion resistance through their own materials to ensure their normal use.

[0025] The top of the circular sleeve 5 is provided with a threaded hole, and the inner wall of the threaded hole is threadedly connected with a threaded rod 7. The top of the threaded rod 7 is fixedly connected with a rotary knob block 8. The bottom of the threaded rod 7 is rotatably sleeved with a fitting sleeve 9. When the bottom of the threaded rod 7 moves downward, it squeezes the fitting sleeve 9 to move downward. After the threaded rod 7 moves upward, the fitting sleeve 9 contacts the bottom of the threaded rod 7 through the compressive elastic force of the spring 10.

[0026] A pressure relief mechanism is arranged inside the circular sleeve 5. The pressure relief mechanism includes a circular gasket 11. The inner wall of the fitting sleeve 9 is fixedly connected with a spring 10. The bottom of the spring 10 is fixedly connected with the top of the circular gasket 11. The bottom of the circular gasket 11 is fixedly connected with a stamping pad 12. The circular gasket 11 is located at the top of the pressure relief pipe 13 through the elastic force of the spring 10 to seal the top of the pressure relief pipe 13. When the air pressure breaks through the elastic force of the spring 10 on the circular gasket 11, the air pressure is discharged from the pressure relief pipe 13.

[0027] The top of the explosion-proof electric cabinet body 1 is fixedly interconnected with a pressure relief pipe 13. The stamping pad 12 is located inside the pressure relief pipe 13. The top of the pressure relief pipe 13 contacts the bottom of the circular gasket 11. A pressure relief hole 14 is opened at the top of the explosion-proof electric cabinet body 1. The pressure relief pipe 13 communicates with the explosion-proof electric cabinet body 1 through the pressure relief hole 14.

[0028] A plurality of heat dissipation fins 15 are uniformly and fixedly connected to the outer wall of the explosion-proof electric cabinet body 1. A plurality of through holes are uniformly opened on the outer walls of the plurality of heat dissipation fins 15.

[0029] Working principle: When in use, when the internal pressure of the explosion-proof electric cabinet body 1 fluctuates greatly or an explosion occurs, the internal air pressure impacts the bottom of the stamping pad 12 through the pressure relief hole 14, causing the stamping pad 12 to move upward and drive the circular gasket 11 to move upward. The upward movement of the circular gasket 11 drives the spring 10 to be compressed. At this time, the circular gasket 11 disengages from the top of the pressure relief pipe 13, and the pressure relief pipe 13 communicates with the circular sleeve 5. The internal air pressure of the explosion-proof electric cabinet body 1 is discharged from the two stainless steel pressure relief nets 6, achieving the purpose of pressure relief, effectively ensuring the integrity of the explosion-proof electric cabinet body 1 and protecting personnel, and avoiding excessive internal pressure in the explosion-proof electric cabinet causing metal deformation and outward diffusion; at the same time, the rotary knob block 8 can be rotated to rotate the threaded rod 7. After the threaded rod 7 rotates to make the fitting sleeve 9 move up and down, the elastic force of the spring 10 and the extrusion force of the bottom of the spring 10 on the circular gasket 11 can be changed, thereby changing the pressure relief value, facilitating the adjustment of explosion-proof electric cabinet bodies 1 of different sizes; the plurality of heat dissipation fins 15 dissipate part of the heat generated by the operation of the electronic equipment inside the explosion-proof electric cabinet body 1, avoiding excessive pressure caused by high internal temperature.

[0030] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments. Obviously, according to the content of this specification, many modifications and variations can be made. This specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can well understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
