Problems solved by technology
The inventors found that the limitation of obtaining fresh water by solar distillation is that it can only be realized during the day and under the conditions of good solar irradiation, and it is impossible to fetch water at night, while all-weather water fetching is important for some areas, and more can be obtained in the same day Fresh water, existing devices cannot achieve all-weather water intake

The invention discloses a portable device capable of obtaining fresh water in all weather and a working method. The problem that in the prior art, all-weather water taking cannot be achieved is solved, and the beneficial effect that fresh water can be effectively obtained in the daytime and at night is achieved. According to the specific scheme, the portable device capable of obtaining fresh water in all weather comprises a first cover and a water taking layer; a water container can be placed on the side portion of the water taking layer; the first cover can be arranged above the water container and the water taking layer to cover the water container; the water taking layer comprises a spectrum selectivity layer and a porous heat insulation layer capable of allowing water to pass through; the spectrum selectivity layer and the porous heat insulation layer are sequentially arranged; the porous heat insulation layer is made of an infrared transmission material; radiation refrigeration is carried out at night through the porous heat insulation layer by transmitting infrared radiation; and the spectrum selectivity layer can absorb solar radiation to heat water sucked by the water taking layer in the daytime.
Description
technical field [0001] The invention relates to the field of water fetching devices, in particular to a portable device and working method that can be used to obtain fresh water around the clock. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Water resources are the primary condition for maintaining the earth's ecological environment and sustainable human development. However, with the increase of the global population and the increasingly serious water pollution, the shortage of water resources is becoming one of the major crises facing the human society. Among the world's total water reserves, sea water accounts for about 97%, fresh water reserves 3%, and fresh water available for human consumption only accounts for 0.3%. Because of the huge reserves of seawater, many people have proposed "asking for water from the ocean", that is, ob...
