technical field

Background technique

The industrialization of marine science and technology is an important part of advanced productivity, and the ocean is the second territory on which people live. With the development of the world economy, the surge of population, and the progress of society, people's demand for energy is increasing day by day. The vast ocean, which accounts for 70% of the earth's surface area, concentrates 97% of the water and contains a large amount of energy, including wave energy, tide energy, ocean current energy, temperature difference energy and salinity difference energy, etc.

The history of ocean energy utilization can be traced back at least to the Middle Ages. In the 11th century, primitive tidal waterwheels were already in operation along the coasts of Galle, Andalusia and England. The idea of using wave energy and temperature difference energy was also proposed as early as the end of the nineteenth century. However, after the 1950s, the large-scale development and research of ocean energy began, firstly tidal energy, then wave energy, temperature difference energy, etc.

The existing power generation device in this field mainly converts mechanical energy into electrical energy through the drive of a single horizontal impeller by water flow. The power generation efficiency is low, the stability of the device is not enough, and the energy conversion rate of the system is low.
