All-closed wave power generation device

Abstract

The invention provides an all-closed wave power generation device. The all-closed wave power generation device comprises a mooring device and a shell; the shell is a closed box with a hollow internal; the bottom of the box is arched; a counterweight block is arranged at the bottom of the shell, and is suspended on an output shaft for transferring power through a connecting rod; the output shaft is horizontally arranged in the shell; the two ends of the output shaft are respectively connected with two opposite inner walls of the box through bearings; when the shell swings along with waves, the counterweight block relatively moves corresponding to the shell under the effect of gravity, and the connecting rod drives the output shaft to rotate; the output shaft is connected with a gear; and the gear spreads rotation of the output shaft to form relative rotation to a power generation device fixed on the shell so as to generate electricity. The all-closed wave power generation device is high in energy capturing efficiency and convenient for use; moving parts are all located in the closed box without being contacted with seawater; the tightness is excellent; and the reliability is high.

Description

Technical field [0001] The invention relates to the technical field of wave energy power generation devices, in particular to a fully enclosed wave energy power generation device. Background technique [0002] With the continuous rapid development of the world economy, the demand for energy in countries around the world has increased dramatically. 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 in social development, it has become the consensus of all countries in the world to find alternative, renewable and clean new energy sources. [0003] The ocean, which accounts for 70% of the earth's area, not only has abundant resources such as aquatic products and oil, but also contains huge energy sources. Ocean energy mainly exists in the form of tides, waves, temperature differences, salinity gradients, and ocean currents. Among them, ocean...

AI Technical Summary

Problems solved by technology

The point absorption power generation device has a small frontal area, low capture efficiency, and limited total energy absorbed, which limits the installed capacity of the power generation device; the surface absorption device is fixed on the seabed, and the frontal surface of the device cannot change with the incoming wave direction. When the wave front is perpendicular to the incoming wave direction, more energy is captured. When the wave front is at a large angle to the wave incoming direction, it is almost impossible to capture energy, which makes the working area of ​​the power generation device narrow and cannot be in the design working condition. dot work

[0010] (3) A large number of submarine constructions and poor recovery and maintenance

Once the wave power generation device is installed in the sea, its maintenance and recovery costs will increase exponentially, even higher than the cost of reproducing a new power generation device
