technical field

The utility model relates to the field of renewable energy power generation technology and marine equipment, in particular to a chain type wave energy power generation device.

Background technique

With the continuous rapid development of the world economy, the demand for energy in all countries in the world is increasing rapidly. The current global oil crisis has made people more aware of the important role energy plays in national economic and social development. In order to solve the bottleneck problem of energy supply encountered in social development, it has become the consensus of all countries in the world to find alternative, renewable and clean new energy sources. As the main body covering 70% of the earth's area, the ocean not only has abundant aquatic products, oil and other resources, but also contains huge energy. Ocean energy mainly exists in the form of tides, waves, temperature differences, salinity gradients, and ocean currents. Among them, ocean wave energy is ubiquitous in the ocean, and is relatively less limited by time. At the same time, wave energy has the largest energy flow density, which can provide considerable cheap energy (mainly electric energy) through smaller devices, and can also Provide assistance for activities such as national defense, ocean development, and agricultural electricity use in remote sea areas.

According to the location where the wave energy device is placed, it can be divided into three categories: offshore type, near shore type, and onshore type. At present, the vast majority of wave energy generation devices are near-shore and onshore. The big problem is that the service life of power generation devices is generally short, and the near-shore and coastal types cannot be used for offshore wave energy generation. It causes a waste of resources.
