This utility model relates to the technical field of underground communication and electrical explosion-proof equipment in
coal mines, and particularly to a flameproof and intrinsically safe gateway for
coal mines. It includes a housing
assembly, a flameproof battery chamber, an intrinsically safe chamber, a battery module, a
data exchange unit, a
power supply unit, a battery information display unit, an intrinsically safe component, an observation window
assembly, a light panel
assembly, an explosion-proof cable entry device, and an explosion-proof cable connector. The housing is made of
metal, and an internal partition divides it into the flameproof battery chamber and the intrinsically safe chamber. The flameproof battery chamber houses the battery module and a
rotary switch that provide independent power to the equipment. The
data exchange unit collects and converts multiple RS485 signals, and the
power supply unit provides intrinsically safe power and monitors the status in real time. The intrinsically safe component in the intrinsically safe chamber converts the signals into standard
Ethernet and optical signals for output to the
ground system. The battery information display unit displays the equipment's operating status in real time through the observation window, and the light panel assembly provides auxiliary lighting. This gateway possesses excellent flameproof and intrinsically safe performance.
