Fan-shaped foldable storage device for sea ice

Abstract

The invention relates to a fan-shaped foldable storage device for sea ice. The fan-shaped foldable storage device for the sea ice is characterized by comprising a bottom cabin and four surrounding cabins, wherein the surrounding cabins are in a shape of isosceles trapezoid, the bottom cabin is in a shape of square, and the surrounding cabins are hinged with the bottom cabin; sealing gaskets are arranged on the peripheral sides wherein the surrounding cabins are in contact with the bottom cabin; synchronous folding bars are arranged on the surrounding cabins, and each of the surrounding cabins and the bottom cabin are respectively provided with a floating tube; multiple fan-shaped foldable storage devices for sea ice are placed above the sea surface, and seawater in the surrounding cabins and the bottom cabin is frozen at the temperature of lower than 0 DEG C; the sea ice starts melting after the temperature rises; the seawater is pumped into the floating tube of the bottom cabin, then the bottom cabin sinks and the surrounding cabins are guided by the synchronous folding bars to synchronously fold to a center, to further form a container; the seawater is discharged from the container; the container can be sealed in a self-reinforcement manner under the pressure of external seawater; and the sea ice in the container melts to obtain fresh water. The invention has the following beneficial effects that: the fan-shaped foldable storage device for sea ice does not occupy any land resource; the device can be folded so that the area occupied by the device on the sea surface can be reduced; and procedures of salvaging and transporting ice can be saved so that a great deal of manpower and energy sources can be saved.

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 desalinating seawater is a method of using winter seawater to freeze and freeze naturally, 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 freezing and melting can rely on natural temperature, no special equipment is needed, and the output is large. For example, the Liaodong Bay area of ​​the Bohai Sea is very rich in sea ice resources, with 3.8 billion m3 of sea ice in perennial ice years and 8.4 billion m3 in light ice years. Billion m3. It can be adopted according to local conditions, which is an economical way to open up water sources. However, storing sea ice is a big problem. The usual method of operation is to use boats to collect crushed ice from the sea when the sea ic...

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
