[0034] The effect achieved is that when the bent pull-up edge 2 is straightened upward, the angle of the bent copper sheet 12 will be changed, thereby releasing the constraint on the top of the contact rod 14. At this time, the lifting plate 24 and the contact rod 14 are pushed upward under the elastic force of the lifting spring 23. When the lifting plate 24 is pushed upward, the push plate 22 is pushed toward the outside of the aluminum capacitor shell 1, thereby driving one end of the positioning rod 20 to extend to the outside of the aluminum capacitor shell 1 and contact the PCB board 3, so that it can position the aluminum capacitor shell 1 and prevent the aluminum capacitor shell 1 from expanding. The top plate 24 will shake, and when it slides upward, the side slide plate 30 will be pulled toward the inside of the regulating chamber 17 through the cooperation between the lever 27 and the inclined groove 31, so that one end of the air guide 32 on the top of the side slide plate 30 is relatively connected with the air inlet 34. At the same time, the upward sliding of the contact rod 14 will cause the upper end of the U-shaped opening 25 to slide into the interior of the explosion-proof chamber 15, thereby introducing the corrosive gas generated inside the explosion-proof chamber 15 into the regulating chamber 17, and then flow into the interior of the neutralization device through the air guide 32 and the air inlet 34.

[0035] like Figure 3 、 Figure 6 and Figure 7As shown, the neutralization device includes an insulating column 13, which is fixed on the sealing plate 28. A copper sleeve 11 is fixed to the bottom of the pad 16. The insulating column 13 is slidably connected between the inner walls of the copper sleeve 11. The bottom of the copper sleeve 11 extends to the top of the sealing plate 28 and fits together. An insulating sleeve 33 is fixed to the top of the pad 16.

A neutralization cavity 35 is provided inside the insulating column 13 near the bottom edge. The inner bottom surface of the neutralization cavity 35 is provided with an air inlet 34 that penetrates to the inner top surface of the side sliding port 29. A plurality of filter discs 41 are fixed equidistantly between the inner walls of the neutralization cavity 35 near the bottom edge. The filter holes on the plurality of filter discs 41 are equidistantly distributed near the outer surface edge. The inner walls of the neutralization cavity 35 are close to each other. A fixing plate 43 is installed near the top edge, and a plurality of air distribution pipes 44 are fixed on the top of the fixing plate 43, which penetrate to the bottom. Filter plugs 45 are provided between the inner walls of the plurality of air distribution pipes 44, and a conical funnel 42 is fixed in the middle between the inner walls of the neutralization chamber 35. The opening of the conical funnel 42 extends obliquely downward, and the bottom of the conical funnel 42 is located in the middle directly above the filter plate 41. A plurality of grid openings 40 that penetrate to the outside are equidistantly provided between the inner walls of the neutralization chamber 35 near the top edge, and a plurality of through-openings 37 that penetrate to the inside are equidistantly provided on the outer surface of the copper sleeve 11 near the bottom edge. An annular cavity 38 is provided between the inner walls of the insulating sleeve 33 near the top edge, and the inner side of the annular cavity 38 is opposite to the grid opening 40. The inner bottom surface of the annular cavity 38 is provided with an exhaust duct 9 that penetrates to the bottom of the sealing plate 28. A sealing ring 39 is fixed between the inner walls of the insulating sleeve 33, and the inner wall of the sealing ring 39 is in contact with the outer surface of the copper sleeve 11.

[0036] The effect achieved is that, first, a neutralizing liquid substance is injected into the neutralization chamber 35, and the corrosive gas flows into the bottom of the neutralization chamber 35 from the air inlet 34. The bubbles will float upward at the bottom and contact the filter 41 during the floating process. Since the filter holes on the filter 41 are close to the edge, and the air inlet 34 is located in the middle of the bottom of the filter 41, the bubbles will diffuse from the middle of the bottom of the filter 41 to the four sides of the edge, and then float upward from the filter holes at the edge of the filter 41. Under the action of the filter holes of the filter 41, the bubbles will The bubbles can be refined to increase their contact area with the neutralizing liquid, which is convenient for neutralizing the corrosive gas in the bubbles. The neutralized gas flows from the bottom of the conical funnel 42 to the multiple gas distribution pipes 44. The liquid can be prevented from entering the upper part under the obstruction of the conical funnel 42. At the same time, the moisture inside the gas is blocked by the filter plug 45 inside the gas distribution pipe 44. The gas flowing out of the gas distribution pipe 44 enters the annular cavity 38 from the grid mouth 40 and the through-hole 37, and is finally discharged from the exhaust duct 9 at the bottom of the annular cavity 38.

[0037] Working principle: When using this device, by setting the explosion-proof cavity 15 and the bent pull-up edge 2 inside the aluminum capacitor shell 1, when high-pressure gas is generated inside the aluminum capacitor shell 1, the bent pull-up edge 2 is straightened under the action of the high-pressure gas, thereby increasing the volume of the explosion-proof cavity 15, thereby buffering the high-pressure gas and cutting off the circuit at the same time. When the bent pull-up edge 2 is straightened upward, the angle of the bent copper sheet 12 is changed, thereby releasing the constraint on the top of the contact rod 14. At this time, under the elastic force of the lifting spring 23, the lifting plate 24 together with the contact rod is lifted. 14 is pushed upward, and when the lifting plate 24 is pushed upward, the push plate 22 is pushed toward the outside of the aluminum capacitor shell 1, thereby driving one end of the positioning rod 20 to extend to the outside of the aluminum capacitor shell 1 and contact the PCB board 3, so that the aluminum capacitor shell 1 can be positioned to prevent the aluminum capacitor shell 1 from expanding and shaking. When the lifting plate 24 slides upward, the side slide plate 30 is pulled toward the inside of the adjustment cavity 17 through the mutual cooperation of the lever 27 and the inclined groove 31, so that one end of the air guide 32 on the top of the side slide plate 30 is relatively connected to the air inlet 34. At the same time, the upward sliding of the contact rod 14 will cause the upper end of the U-shaped opening 25 to be opened. The square end slides into the explosion-proof chamber 15, thereby introducing the corrosive gas generated in the explosion-proof chamber 15 into the regulating chamber 17, and injecting a neutralizing liquid substance into the neutralization chamber 35. The corrosive gas flows into the bottom of the neutralization chamber 35 from the air inlet 34, and the bubbles will float upward at the bottom. In the process of floating, they will come into contact with the filter 41. Since the filter holes on the filter 41 are close to the edge, and the air inlet 34 is located in the middle of the bottom of the filter 41, the bubbles will diffuse from the middle of the bottom of the filter 41 to the four edges, and then from the filter holes at the edge of the filter 41. Floating upward, the bubbles can be refined under the action of the filter holes of the filter 41, and the contact area between the bubbles and the neutralizing liquid is increased, which is convenient for neutralizing the corrosive gas in the bubbles. The neutralized gas flows from the bottom of the conical funnel 42 to the multiple gas distribution pipes 44. The liquid can be prevented from entering the upper part by the obstruction of the conical funnel 42. At the same time, the moisture inside the gas is blocked by the filter plug 45 inside the gas distribution pipe 44. The gas flowing out from the gas distribution pipe 44 enters the annular cavity 38 from the grid mouth 40 and the through-hole 37, and is finally discharged from the exhaust duct 9 at the bottom of the annular cavity 38.
