[0019] By setting up a protective chamber, gas treatment tank, dry powder storage tank, and explosion-proof protection mechanism, during use, the control panel is opened, and the installation slider is positioned after adjustment using the second positioning bolt for easy adjustment during maintenance. The top of each positioning sleeve is threaded with a third positioning bolt, which is used to reinforce the positioning sleeve and connecting rod. Extinguishing agent is dispensed through the first and second dry powder outlet pipes to assist in extinguishing fires in case of internal accidents, thus achieving explosion-proof protection. Two dry powder storage tanks are located on either side of the gas treatment tank. The fire pump operates, delivering the required extinguishing agent to the dry powder storage tank through connecting pipes to assist in internal explosion-proof protection. The control panel controls the operation of the fire pump and valves, achieving unified management of electrical equipment. The gas treatment tank and sealing base plate are secured using the mounting base plate and the first positioning bolt. The reinforced connections improve the stability of the equipment during operation. Reinforced side plates support the positioning and strengthening rails, while an explosion-proof top plate protects the top of the protective chamber, and a moisture-proof bottom plate protects the bottom. An internal cavity within the protective chamber facilitates the installation of the explosion-proof protection mechanism. An inspection door allows easy access for maintenance. The protective chamber, explosion-proof top plate, and sealed bottom plate provide primary external explosion protection.
