The invention relates to a seawater freshening device using tidal energy. The seawater freshening device comprises a buoy, a water storage device, a seawater freshening film assembly, a support structure and a guide column, wherein the buoy is arranged at the top part of the water storage device; the bottom part of the water storage device is fixedly arranged on the bottom plate; the side wall ofthe water storage device is provided with wrinkles for extending and retracting; the support structure comprises a plurality of vertical columns which are fixedly connected with the bottom part of thebottom plate; the other end of each of the multiple vertical columns is fixedly arranged at the sea bed; the guide column is vertically and fixedly arranged at the upper part of the bottom plate, andthe upper end of the guide column penetrates through the buoy; the guide column is glidingly connected with the buoy, and the buoy can be moved up and down along the guide column to drive the water storage device to extend and retract; the seawater freshening film assembly is positioned under the bottom plate, vertically penetrates through a through hole which is formed in the bottom plate, and is communicated with the water storage device; an air exhaust passage is arranged at the top part of the water storage device; the upper end of the air exhaust pipeline penetrates through the buoy, andis used for sealing the water storage device through an airtight valve; a water drain pipe is arranged at the bottom part of the water storage device, and is used for communicating the water storagedevice and a water tank on the bank; a check valve is arranged on the water drain pipe.
Description
technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a seawater desalination device utilizing tidal energy. Background technique [0002] Tidal energy refers to the potential energy of water formed by the rise and fall of seawater. It is a renewable energy source with a clean and pollution-free environment, and it is also a relatively stable and reliable energy source. The tide rises and falls every day, and it is repeated every week. It is inexhaustible and inexhaustible. The full development and utilization of tidal energy can not only save the increasingly depleted conventional energy and alleviate the severe shortage of resources, but also reduce pollution and protect the ecological environment on which human beings depend. The energy of tidal energy is huge, and how to effectively use it has become a hot research topic. Currently, tidal energy is mainly used to generate electricity. On the other hand, using a l...
