Integrated solar water purification, power generation and hydrogen production system

The invention discloses an integrated solar water purification, power generation and hydrogen production system which comprises a floating plate, a device shell, a distillation and hydrogen production device, a storage battery, a control system, a seawater taking and purifying device, a hydrogen storage bottle and a water storage bottle. The floating plate floats on the sea surface and is internally provided with a groove embedded into the device shell, so that internal equipment is protected from being impacted by the external environment. A rotating mechanism is arranged above the device shell and connected with the solar photovoltaic panel, and the rotating mechanism can adjust the orientation and the inclination angle of the photovoltaic panel so as to achieve maximum utilization of solar energy. Seawater purification, solar power generation and hydrogen preparation are integrated on the same floating platform, the number and occupied space of equipment are reduced, and the device is suitable for seaborne and space limited scenes. The condensation aluminum plate is in contact with seawater to keep low temperature, and the aerogel layer reduces heat loss and improves distillation efficiency; the carbon black nanofluid is heated to increase the electrolysis temperature, and the hydrogen production rate is increased; structural modular design is adopted, the shell and other components can be manufactured through 3D copying, and batch production and rapid deployment are facilitated.
