Problems solved by technology

Its disadvantage is that it consumes a lot of energy and corresponding labor when sailing and fishing for ice.
Secondly, there must be a huge sea ice storage and melting site on land, occupying valuable land resources

Abstract

The invention relates to a method for making fresh water by fan-shaped foldable sea ice storage devices. Each fan-shaped foldable sea ice storage device is characterized by comprising a bottom cabin plate and four enclosure cabin plates, wherein each enclosure cabin plate is in the shape of an isosceles trapezoid, the bottom cabin plate is in the shape of a square, and the enclosure cabin plates are hinged with the bottom cabin; the contact periphery of the enclosure cabin plates and the bottom cabin is provided with a sealing gasket; the enclosure cabin plates are provided with synchronous folding strips, and the enclosure cabin plates and bottom cabin plate are respectively provided with a float bowl; a plurality of devices are put on the sea in a planar mode, and seawater in the enclosure cabin plates and bottom cabin plate becomes ice when the air temperature is lower than 0 DEG C; when the air temperature rises, the sea ice starts to melt; when the seawater is sucked into the float bowl of the bottom cabin plate, the bottom cabin plate sinks, and the enclosure cabin plates are synchronously folded towards the center under the guide of the synchronous folding strips to form a container; when the seawater in the container is evacuated, self-reinforced seal of the container is formed under the pressure of the outside seawater; and when the sea ice in the container melts, the fresh water is obtained. The invention does not occupy the land resources; the devices are foldable, thereby reducing the occupied area on the sea surface; and the invention saves the procedure of dredging and transporting ice, thereby saving abundant human and energy sources.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a device for desalinating seawater by using natural energy. Background technique [0002] The natural freezing method of seawater desalination is to use the natural freezing and freezing of seawater in winter, take the ice to melt, and discharge a small amount of brine in the ice to obtain fresh water. The advantage of this method is that the freezing and melting can rely on natural temperature, no special equipment is needed, and the output is very large. For example, the sea ice resources in the Liaodong Bay area of ​​the Bohai Sea are very rich. 100 million m3. It can be adopted according to local conditions, which is an economical method of developing water sources. Yet storing sea ice is a big problem. The usual operation method is to use ships to fish for crushed ice from the sea when the sea ice melts, and then transport it to land to melt the ice in the natural env...
