[0031] Working principle: In use, when the temperature drops at night, when the airflow carrying mist droplets passes through the surface of the mist-catching net 201, the mist droplets cannot be bypassed by the airflow due to inertia and directly hit the surface of the mist-catching net 201. When the weight of the accumulated water droplets exceeds the surface tension, they will be drawn downwards and gather into the center of the mist-catching net 201 by gravity, forming fresh water. This water is then dripped into and collected inside the liquid storage hopper 301. In the early morning, before the water evaporates, the water pump 304 is started. The water pump 304 guides the fresh water along the liquid guiding hose 305 into the water spray nozzle 307, and then sprays it out from the water spray nozzle 307, thereby rinsing the water pump 304, the energy control and management module 401, the large-capacity energy storage capacitor module 402, the hydrogen production management module 403, the seawater hydrogen production module 404, and the hydrogen storage module 405. In weather with poor light, the fresh water can be stored to accumulate more for rinsing. During rainy weather, rainwater drips onto the surface of the guide shading hopper 308 and then flows along the guide shading hopper 308 into the interior of the storage hopper 301, thereby achieving freshwater collection.
