Problems solved by technology

In particular, agricultural plant protection drones are facing the erosion of liquid medicine and water penetration, geological exploration drones are facing environmental tests with unpredictable acidity and alkali, and the impact of water or fire extinguishing agents sprayed by fire-fighting drones, etc. Flying in these harsh environments, if the plug used by the drone does not have waterproof and dustproof functions, then the positive and negative electrical connectors of the plug are prone to leakage, short circuit, etc., causing air bombing or crashing
