Detailed ways

The specific embodiments of the present invention are provided below with reference to the accompanying drawings, which are used to further describe the structure of the present invention.

Example 1

A kind of offshore wave power generation device of this embodiment includes a buoyant bucket I1, and the buoyant bucket I1 is connected with a compression chamber I2 that can be retracted and extended and contains hydraulic oil, and the compression chamber I2 is connected with the buoyant bucket III14 through a hydraulic pipe I3 , the inside of the buoy bucket III14 is provided with a hydraulic engine I 4 that is connected to the hydraulic pipe I 3, and the hydraulic engine I 4 is connected to one side of the two-way rotating generator 6 through the transmission shaft I 5, and the other side of the two-way rotating generator 6 The drive shaft II 7, the hydraulic engine II 8, the hydraulic pipe II 9, the compression chamber II 10, and the buoy II 11 are connected in turn. Compression chamber I 2 and compression chamber II 10 are made of bendable rigid metal material; compression chamber I 2 and compression chamber II 10 are provided with a steel frame for preventing them from excessive bending.

Working principle: The fluctuation of sea waves causes a drop between two adjacent buoys and buoys I 1 and buoy II 11, causing the compression chamber I 2 and compression chamber II 10 between them to be squeezed and squeezed. Twisting, so that the hydraulic oil in the compression chamber is filled with huge side pressure. This pressure is transmitted to the hydraulic engine through the hydraulic hydraulic pipe and drives the hydraulic engine to work. The hydraulic engine drives the two-way rotating generator through the transmission shaft to generate electricity. The compression chamber is composed of It is made of bendable rigid material, provided with a steel frame to prevent excessive bending, and a speed regulating control device 15 is provided between the hydraulic motor and the two-way rotating generator, because the rotor 12 and the stator 13 of the two-way rotating generator are reversed Rotation can obtain more electric energy, while the never-ending wave provides unlimited kinetic energy. Because of the two-way rotating generator, a power generation device must be composed of at least three buoys and two compression chambers. If the If it is connected in series to become a dragon, the power generation capacity will be greatly improved. The electricity generated by the two-way rotating generator can be connected to the substation to enter the grid, and can also be stored in the storage battery after being rectified.

The offshore wave power generation device of this embodiment has a reasonable structural design and high power generation efficiency. Since the sea level is constantly churning, the buoyant barrel is always squeezing and stretching the compression chamber, so that the hydraulic oil in the compression chamber generates a huge side pressure. Pressure, the pressure transmits kinetic energy to the hydraulic generator through the hydraulic tube, drives the hydraulic generator to work, and the hydraulic generator drives the two-way rotating generator to work, thereby generating a steady stream of electric energy.
