Description

technical field [0001] The invention relates to the field of utilization of ocean energy and solar energy, in particular to a new comprehensive utilization system of ocean energy for combined hydropower generation. Background technique [0002] The ocean is a huge "energy pool", which contains abundant solar energy, wind energy, tidal energy, wave energy, and temperature difference energy. These energy sources have the advantages of being renewable, widely distributed, huge in energy, and non-polluting, and are important for future energy development. direction, among which wave energy is one of the relatively mature technologies. Wave energy is ubiquitous and abundant in the ocean. The wave energy generation system generally has an energy absorption device and an energy conversion device. The energy absorption device absorbs wave energy and converts it into a function of regular motion (such as linear motion, circular motion), and then converts the mechanical energy of the...

[0006] The purpose of the present invention is to solve the problem of poor energy in coastal and island areas, and to solve the existing problems of utilization of temperature difference energy, and propose a new type of comprehensive utilization system of ocean energy for hydropower cogeneration. The present invention takes ocean temperature difference energy power generation as the core , reasonably matched with renewable energy such as wave power generation devices and solar ponds, the system can provide multiple outputs at the same time, produce fresh water while generating electricity, and the solar pond increases the temperature of warm sea water, increases the flash ratio, and reduces the volume of the flash chamber. Use the electricity generated by the abundant wave energy on the ocean to provide the power of the seawater pump in the ocean energy thermoelectric power generation system, reduce the dependence of the thermoelectric power generation system on external energy, and even realize the energy self-sufficiency of the entire system. These features are very useful for isolated islands and other areas where energy is scarce. , not only solved the problem of electricity consumption but also solved the problem of water use to a certain extent
