Description

Power generation buoy using ocean wave energy and solar energy

technical field

The utility model relates to a hybrid buoy which uses wave energy and solar power to generate energy for a monitoring system on the sea, and is a power generation device for the development and utilization of new energy and a hydrometeorological multifunctional monitoring buoy.

Background technique

With the rapid development of human science and technology, energy resources such as oil and natural gas that can be directly exploited by human beings are increasingly scarce, so the development and utilization of new energy is a boom in the world today. The ocean area is vast, accounting for about 71% of the earth's surface area, and has great potential. The use of wave energy to generate electricity is now a new technology, and solar energy is relatively mature.

Most of today's ocean power generation devices use solar power generation and batteries alternately to supply power to working equipment or monitoring systems. Obviously, the above-mentioned existing power supply forms do not have continuity, safety and reliability. Although solar power generation is very common nowadays, there are also problems such as insufficient energy supply and poor stability for unpredictable sea conditions, and the use of piezoelectric wave energy power generation devices can directly convert wave energy into electrical energy through the deformation of piezoelectric materials , more durable and stable than solar power. Combining the two, this provides a very feasible technical solution for powering offshore monitoring equipment.

Due to the complex and changeable marine environment, the functions of marine monitoring buoys are generally relatively single. The current marine monitoring buoys usually only have individual functions in marine data monitoring such as hydrology, water quality, meteorology, and environment. As far as the buoy itself is concerned, the scalability and compatibility are insufficient, and it is difficult to meet the various needs of ocean monitoring.

And solar energy is converted into electrical energy for various sensors.
