AI Technical Summary
In the event of a deflagration, the high-temperature and high-pressure gas in existing mining explosion-proof power supplies cannot escape quickly, leading to damage to the explosion-proof casing or an explosion, threatening personnel safety and potentially causing a larger accident.
Design an explosion-proof power supply housing structure with a buffer mechanism, including a buffer box, a pressure plate, a top plate, and a fixed cylinder. The gas pressure generated by the deflagration is released through the buffer box and the pressure relief hole, thereby reducing the impact force.
It effectively buffers and releases pressurized gas inside the power supply box, preventing damage to the casing and avoiding sudden gas ejection that could injure surrounding equipment or personnel.

DETAILED DESCRIPTION
[0022] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described in combination with specific embodiments.
[0023] As Figures 1-5 The utility model discloses a kind of new mine explosion-proof power supply's shell structure provided by the utility model, including explosion-proof power supply box 1, explosion-proof power supply box 1 side fixed installation has wire box 3, explosion-proof power supply box 1 front side movable installation has front cover 2, front cover 2 front side movable installation has multiple control buttons 4, and control button 4 is electrically connected with electrical equipment in explosion-proof power supply box 1 by connecting wire, buffer mechanism 5 is provided in the top of explosion-proof power supply box 1, buffer mechanism 5 includes buffer tank 6, pressure plate 7, top plate 8, buffer tank 6 is fixedly installed in the top of explosion-proof power supply box 1, pressure plate 7 is movably installed in buffer tank 6, top plate 8 is fixedly installed in the top of buffer tank 6, and fixed cylinder 9 is fixedly installed in the bottom of top plate 8.
[0024] Explosion-proof power supply box 1 top center position is provided with mounting hole 24;
[0025] As Figures 2-5As shown, a lower fixed flange 10 is fixedly installed at the bottom of the buffer box 6, and an upper fixed flange 11 is fixedly installed at the top of the buffer box 6. Multiple reinforcing plates 12 are fixedly installed on the outside of the buffer box 6 between the lower fixed flange 10 and the upper fixed flange 11. A sealing groove 13 is opened on the inner side of the upper fixed flange 11, and a pressure inlet hole 14 is opened at the center of the bottom of the lower fixed flange 10. A first convex ring 15 is also fixedly installed on the buffer box 6 below the pressure inlet hole 14. A sealing seat 16 is fixedly installed at the bottom of the buffer box 6. The sealing seat 16 is arranged along the inner contour of the buffer box 6 and has a rectangular structure. The buffer box 6 is fixedly installed on the explosion-proof power supply box 1 via the lower fixed flange 10, and the first convex ring 15 is inserted into the mounting hole 24. Based on this, through the buffer box 6, the pressure inlet hole 14, and the first convex ring 15, the expansion pressure inside the explosion-proof power supply box 1 can enter the buffer box 6, thereby releasing and buffering the pressure inside the explosion-proof power supply box 1. A second convex ring 17 is fixedly installed at the center of the bottom of the pressure plate 7. A movable cylinder 18 is fixedly installed at the center of the top of plate 7. The pressure plate 7 is inserted into the bottom of the buffer box 6 and located within the sealing seat 16. The second convex ring 17 is inserted into the pressure inlet hole 14. A sealing flange 19 is fixedly installed at the bottom of the top plate 8. The top plate 8 located inside the fixed cylinder 9 has multiple first pressure relief holes 20. Multiple second pressure relief holes 21 are opened on the inner side of the fixed cylinder 9. A limit ring 22 is fixedly installed in the fixed cylinder 9 below the second pressure relief holes 21. The top plate 8 is inserted into the upper fixed flange 1. The top is fixed with bolts, and the sealing flange 19 is inserted into the sealing groove 13. The fixed cylinder 9 is inserted into the movable cylinder 18. A compression spring 23 is inserted into the fixed cylinder 9 located between the movable cylinder 18 and the top plate 8. Based on this, the pressure plate 7 is inserted into the buffer box 6. With the top plate 8, the fixed cylinder 9 and the compression spring 23, the pressure entering the buffer box 6 can be buffered and released through the second pressure relief hole 21 and the first pressure relief hole 20, reducing the impact force of pressure release.
[0026] It should be noted that this utility model is a new type of shell structure for a mine explosion-proof power supply. When the electrical equipment inside the explosion-proof power supply box 1 explodes, the pressure gas generated by the explosion will push the pressure plate 7 upward. Then, the pressure plate 7 compresses the compression spring 23 towards the bottom of the top plate 8 through the movable cylinder 18, while the limiting ring 22 on the inner side of the fixed cylinder 9 restricts the maximum upward movement of the movable cylinder 18 in the fixed cylinder 9. At the same time, the pressure plate 7 moves upward in the buffer box 6 and disengages from the sealing seat 16, so that the pressure gas inside the explosion-proof power supply box 1 can enter the buffer box 6 through the pressure inlet hole 14, which can play the role of releasing the pressure inside the explosion-proof power supply box 1. At the same time, the pressure gas entering the buffer box 6 is initially buffered and then discharged through multiple second pressure relief holes 21 on the inner side of the fixed cylinder 9 and the first pressure relief hole 20 in the top plate 8, so that the pressure gas inside the buffer box 6 is released after buffering, thereby preventing further damage to the explosion-proof power supply box 1.
