The working principle of the invention is as follows:
In daytime, the three-way valve 10 is communicated with the air guide port 8 and the exhaust pipeline 11. The photovoltaic heat collecting shed 18 is irradiated by solar radiation, and part of radiation energy is converted into electric energy through the photovoltaic heat collecting shed 18; the solar energy which is not converted into electric energy in the photovoltaic heat collecting shed 18 is converted into heat energy which is absorbed by the battery, and the photovoltaic heat collecting shed 18 transfers the heat to the salt pan 1 and the air between the salt pan 1 and the photovoltaic heat collecting shed 18 in a radiation, convection and heat conduction heat transfer mode. The heat absorbed by the salt pan 1 is used for heating the salt pan 1 to perform salt making operation, and is stored by soil heat accumulation; after the heating process, the air in the photovoltaic heat collecting shed 18 is reduced in density due to heat absorption, and the hot air with reduced density flows along the photovoltaic heat collecting shed 18 under the action of buoyancy force and enters the chimney 17 and leaves through the chimney outlet 4 to form a wind drawing effect. Under the action of the wind-drawing effect, cold air outside the photovoltaic heat-collecting shed 18 enters through the photovoltaic heat-collecting shed inlet 2, so that continuous flow of air in the photovoltaic heat-collecting shed 18 is formed. The hot and humid air is subjected to condensation heat exchange with cold air flowing in the condensation heat exchange device 6 to generate condensed water; the condensed water generated by condensation heat exchange has higher potential energy, can push the water conservancy turbine generator 5 to generate electricity hydraulically, can be used for industry and life after being collected, can also use the water in the water tank 14 to clean the photovoltaic components of the photovoltaic heat collection shed 18 when needed, and ensures that the photovoltaic power generation is stable and reliable. When flowing through the inner surface of the photovoltaic heat collection shed 18, the flowing air can take away heat generated by the back plate of the photovoltaic module in the photovoltaic heat collection shed 18, so that the power generation performance of the photovoltaic module is greatly improved; meanwhile, the flowing air can continuously take away the water vapor generated by the salt pan 1, so that the salt pan 1 and the air flow above the salt pan always maintain higher mass transfer potential difference, the salt making effect of the salt pan is enhanced, and the salt making efficiency is improved.
At night, the three-way valve 10 communicates the air guide port 8 with the regenerative pipe 12. The heat-stored soil begins to release heat outwards to heat the air between the salt pan 1 and the photovoltaic heat-collecting shed 18 and the salt pan 1, so that the system still has the capabilities of salt making, fresh water preparation and hydroelectric power generation at night. The hot and humid air and the cold air flowing in the hot and humid air are subjected to condensation heat exchange through the condensation heat exchange device 6, the temperature of the cold air outside the heat exchange is raised, the cold air enters the backheating pipeline 12 through the three-way valve 10 and flows back into the photovoltaic heat collection shed 18, and the purpose of heat recycling can be achieved.
