Description

technical field [0001] The invention relates to the field of digital coal mine 5G intelligent technology, in particular to a mining explosion-proof and intrinsically safe 5G wireless base station cooling device. Background technique [0002] The air of coal mines contains gas and coal dust, and the gas and coal dust content reaches a certain amount. Under the action of ignition source or high-temperature heat source, it is easy to cause dangerous combustion and explosion, resulting in heavy loss of personnel and property; while electrical equipment is running The generation of electric sparks in coal mines is one of the main reasons for combustion and explosions in coal mines. Therefore, the "Coal Mine Safety Regulations" stipulates that all electrical equipment used in mines must be explosion-proof; 5G intelligence in digital coal mines is conducive to production safety monitoring and management. Based on the needs of comprehensive information services, production schedulin...
