The power supply assembly is connected with the water scraping assembly and provides a power supply for the water scraping assembly.
The reservoir 4 and the fresh water collecting module 5 are provided with mounting cavities 8 in a penetrating manner, photo-thermal material pieces 9 are mounted in the mounting cavities, and condensing pipes 10 are arranged on the inner walls of the mounting cavities; an overheated fresh water pool 41 is arranged at the upper end of the impounding reservoir 4, a cooling fresh water pool 42 is arranged at the lower end of the impounding reservoir, the overheated fresh water pool is connected with the water inlet of the condensation pipe, the cooling fresh water pool is connected with the water outlet of the condensation pipe, and a fresh water transportation pipeline 43 is arranged on the cooling fresh water pool; the superheated fresh water pool is communicated with the fresh water collecting module 5.
The photo-thermal material piece 9 is made of a photo-thermal material which is strong in hydrophilicity and has certain corrosion resistance, the lower end of the photo-thermal material piece is in contact with seawater, and due to the hydrophilicity of the photo-thermal material piece, the seawater can be transported from the sea level to the upper end of the photo-thermal material piece for evaporation, so that the continuous supply of the seawater is realized. Through the hydrophilic performance of light and heat material spare, can guarantee the supply of sea water, reduce the use of water pump, reduced the dependence of whole sea water desalination to the electric energy, practiced thrift the power consumption and reduced the running cost.
The seawater is absorbed from the lower surface to the upper surface of the photo-thermal material piece, and in this example, the upper end of the photo-thermal material piece is provided with a hemispherical shape, which enables a larger area to receive the solar radiation and evaporate. When the solar radiation is low and the evaporation rate of the seawater is less than the water supply rate of the photo-thermal material piece, the redundant seawater enters the installation cavity along with the hemispherical surface of the photo-thermal material piece and returns to the sea level again, and the redundant seawater is prevented from entering the fresh water collecting module to pollute the desalinated fresh water.
After the seawater arrives at the hemispherical surface of the upper end of the photothermal material piece, through the irradiation evaporation of sunlight, water vapor arrives at the inner surface of the glass outer cover, and other soluble substances such as salt and the like are temporarily left in the photothermal material piece. When water vapor moves to the inner surface of the glass outer cover, the water vapor is condensed into fresh water at the inner surface, one part of the fresh water enters the fresh water collecting module along the inner surface of the glass outer cover under the action of gravity and self viscosity, then enters the superheated fresh water pool of the impounding reservoir under the action of gravity, the other part of the fresh water is condensed into a water film on the inner surface of the glass outer cover, the water scraping component acts at the moment, the water film on the inner surface of the glass outer cover is scraped, the cleanness of the glass outer cover is ensured, the transmission of sunlight is not weakened, the water film enters the fresh water collecting module, and finally the water film enters the superheated fresh water pool of the impounding reservoir.

The top in the overheated fresh water pond of cistern is sheltered from by fresh water collection module and installation cavity etc. sunshine can't shine the fresh water in the overheated fresh water pond, has avoided evaporating once more of fresh water to cause the inside vapor pressure increase of evaporimeter, reduce evaporation efficiency and influence the problem of fresh water energy.
Be equipped with the condenser pipe on the inner wall of installation cavity, light and heat material spare is hugged closely with the condenser pipe, and the overheated fresh water in the overheated fresh water pond gets into from the water inlet of condenser pipe, later enters into the cooling fresh water pond from the delivery port of condenser pipe. Because the hydrophilic performance of light and heat material spare transports the sea water and evaporates on its hemispherical surface of upper end, consequently, the sea water must pass through the inside of light and heat material spare, because light and heat material spare is hugged closely with the condenser pipe, consequently, the sea water must pass through the surface of condenser pipe, combine the whole process of the sea water evaporation of the aforesaid narration, get into the overheated fresh water pond after the vapor condensation in, the temperature of fresh water this moment is higher, utilize the waste heat of fresh water this moment, preheat for the sea water in the light and heat material spare through the condenser pipe, then get into the cooling fresh water pond through the condenser pipe in, carry out abundant utilization to the heat. And finally, the fresh water in the cooling fresh water pool enters a water storage tank for storing fresh water in the marine residential quarters through a fresh water transportation pipeline.
In some embodiments, the floating floor 1 is inclined from the periphery to the direction of the mounting through hole, and the height thereof is gradually reduced.
Influence of marine rainy day weather and wave, can lead to floating the board and go up to amass sea water and rainwater, if lean on natural evaporation to handle ponding, need longer a period, be provided with power supply unit on the floating bottom plate, if power supply unit receives sea water or rainwater for a long time and soaks, can cause the influence or shorten life to its normal use function, and power supply unit if adopt photovoltaic module, the sea water or the rainwater of overstock on photovoltaic module can influence photovoltaic module's generating efficiency, consequently, the floating bottom plate is by all around to the slope of installation through-hole direction, make ponding collect along the central point of floating the bottom plate.
A rainwater collecting through groove 11 is formed in the periphery of the mounting through hole 2, and a rainwater collecting cavity 44 communicated with the rainwater collecting through groove is formed in the wall of the reservoir; be equipped with rainwater transport pipe way 45 on the rainwater collection chamber, the structure setting of showy bottom plate is convenient for ponding flow direction showy center of bottom plate to in leading to the groove entering into rainwater collection chamber through rainwater collection, marine resident's accessible rainwater transport pipe way is stored the rainwater and is utilized.
In some embodiments, the lower end of the water reservoir 4 is provided with a filter screen 12 for filtering the marine garbage, so as to prevent the lower end of the photo-thermal material from being blocked and affecting the desalination efficiency.
The existing seawater desalination system does not pretreat seawater, so that the service life of a seawater supply system is rapidly reduced due to blockage caused by the seawater garbage and the like, and the running cost of the system is undoubtedly increased by frequently cleaning and repairing the seawater supply system. This example sets up the filter screen at the lower extreme of cistern, and this filter screen can filter most ocean rubbish and prevent it to enter into light and heat material spare, has avoided light and heat material spare lower extreme to cause the jam because of ocean rubbish. And because the ocean is a flowing system, the marine garbage remained on the filter screen can leave the filter screen along with the flowing of the ocean, and the accumulation of the garbage on the filter screen is avoided.
