Technical Field
[0001] The utility model belongs to the technical field of explosion-proof lamps, and in particular relates to a safety lamp with a gas early warning function used in coal mine mining. Background Art
[0002] Safety lamps, also known as explosion-proof lamps, are mainly used in dangerous places where flammable gases and dust exist. The explosion-proof principle is to isolate the explosive gases and explosive dust from the outside world to prevent the electric arc and sparks generated inside the lamp from igniting the explosive gases and explosive dust from the outside world. During coal mining, a large amount of coal ash will adhere to the surface of the lampshade of the safety lamp. The existing safety lamps do not have a self-cleaning function. The coal ash adhering to the surface of the lampshade will affect the lighting effect. Moreover, the existing safety lamps cannot detect and warn of the gas concentration in the coal mine, and have poor safety performance. Utility Model Content
