[0002] The mining flameproof and intrinsically safe DC regulated power supply is a special power supply that can be used in gas and coal dust explosion hazardous environments. It is a power conversion device dedicated to the hydraulic support electronic control system. It connects to the 127V AC power supply from the working face power lighting circuit, converts it into DC 12V, and supplies power to the hydraulic support electro-hydraulic control system. The power supply has dual over-current and over-voltage protection functions and has two sets of output circuits.

[0003] The Chinese patent publication number is CN218071295U, which discloses a flameproof and intrinsically safe DC regulated power supply for mining. The heat inside the shell can be transferred and cooled more quickly through the heat conduction plate and the fan, thereby ensuring the temperature inside the shell and avoiding the occurrence of equipment overload and short circuit. At the same time, the scraper can be moved through the push plate, the screw rod and the threaded sleeve to scrape and clean the dust on the surface of the heat conduction plate, thereby making the heat dissipation efficiency of the heat conduction plate faster.

[0004] However, there are still the following disadvantages: when the device is in use, an external wiring harness needs to be connected to the explosion-proof connector.
