During the circulation of the liquid, the liquid will pass through the circulation tank, when the liquid circulates anticlockwise, the liquid will flow in from the liquid tank 10 and flow out from the gas-liquid tank 9, so that the liquid will only carry away the liquid when flowing through the circulation tank, neon gas will gather at the top of the gas-liquid tank 9 and will not flow with the liquid, the same circulation will only replace the liquid with slightly higher temperature inside the focal length adjusting chamber with the low temperature liquid inside the lighting device, when the liquid circulates clockwise, the liquid flows into the gas-liquid tank 9 and flows out of the liquid tank 10, so that when the liquid flows out of the gas-liquid tank 9, the neon at the top of the gas-liquid tank 9 is driven to flow along with the liquid, the circulation can replace the liquid inside and outside the lighting device and increase the content of neon for the lighting device, thereby improving the overall brightness of the lighting device and prompting the temperature change of workers;
the circulating pump 8 is continuously started in the working process of the explosion-proof lighting device, so that the liquid in the lighting device continuously circulates in the circulating pipeline 14, the temperature of the liquid in the lighting device can continuously absorb the heat generated by the lighting device in the working environment due to the fact that the focusing adjusting cavity is closest to the external working environment, the circulating pump 8 can continuously circulate the liquid in the lighting device and the liquid outside the lighting device, and therefore the high-temperature liquid and the low-temperature liquid can circulate, the temperature of the lighting device and the temperature of the whole working environment are reduced, and the possibility of explosion of the lighting device is reduced;
the first valve port 15 and the third valve port 17 are separated and crossed, the second valve port 16 and the fourth valve port 18 are in a straight-through shape, the left side of the reversing valve 11 is provided with a supporting spring, the right side of the reversing valve is provided with an expansion air cavity, the circulating pipeline 14 is communicated with the expansion cavity 19, when the temperature of liquid flowing in the expansion cavity 19 is low, the supporting spring pushes the movable valve body to move rightwards, at the moment, the power supply 12 is connected with the circulating pump 8 through the first valve port 15 and the third valve port 17, the circulating pump 8 rotates clockwise, so that the circulating pump 8 drives the liquid in the circulating pipeline 14 to rotate anticlockwise, otherwise, when the temperature of the liquid flowing in the expansion cavity 19 is high, the expansion air bag expands by heating, the movable valve body is pushed to the left side, at the moment, the power supply 12 is connected with the circulating pump 8 through the second valve port 16 and the fourth, the circulating pump 8 which originally rotates clockwise rotates anticlockwise, and the liquid in the circulating pipeline 14 rotates clockwise in the circulating pipeline 14, so that the brightness of the lighting device can be automatically adjusted through the temperature of the liquid sensed in the expansion cavity 19, and a worker can know the temperature change without using other equipment;
when the device works in a mine, sound is generated without fail, the sound generates vibration, when saturated carbonated water in the solution convex lens 7 senses sound transmitted from a certain direction, the saturated carbonated water becomes unstable under the vibration of the sound, so that the carbonated water is decomposed into carbon dioxide gas and water, then the carbon dioxide enables the solution convex lens 7 to expand, the solution convex lens 7 facing to the sound side expands, the solution convex lens 7 not facing to the sound side does not expand, the expanded solution convex lens 7 can guide light which is originally focused by the convex lens II 5 to the direction of the sound for fixed point focusing, the whole lighting device can focus the light towards a working position for fixed point focusing, the light of a working environment is more sufficient, meanwhile, when the solution convex lens 7 expands, the liquid pressure in the circulating pipeline 14 is increased, and the proportion of neon blended into pure water is increased after the liquid pressure is increased, so that the overall brightness of the lighting device can be higher in operation than in non-operation period.
