[0002] The use of ocean energy is the direction of energy research in the world today. Especially in the situation where energy is related to national security, the earth's mineral energy is gradually exhausted and the environmental conditions are deteriorating, how to effectively utilize the rich and renewable ocean resources is very important. Inertial wave power generation technology is based on the existing research on the use of ocean wave energy for power generation, and uses mature mechanical manufacturing and power generation technologies for effective combination.

[0003] Wave power generation is a technology that converts wave energy into electrical energy. The principle of wave power generation is to convert wave energy into mechanical energy, air pressure or hydraulic energy, and then drive the generator to generate electricity through a transmission mechanism, gas turbine, water turbine or hydraulic motor.

[0004] At present, offshore power generation equipment includes wave power generation equipment and wind power generation equipment, but traditional wave power generation equipment can only convert the energy of ocean waves. When ocean waves appear, strong ocean breezes must appear at the same time. Single wave power generation equipment cannot realize the conversion and utilization of ocean breeze energy, resulting in energy waste. Therefore, the present invention proposes a multifunctional wave energy power generation device to solve the problems existing in the prior art. Summary of the invention

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1-Figure 6 As shown, this embodiment provides a multifunctional wave energy power generation device, including a base frame 1, a sliding guide rod 2, a power generation transmission mechanism, a float 3 and a wind power generation mechanism. The base frame 1 is triangular, and the sliding guide rods 2 are symmetrically arranged on the upper side thereof. The sliding guide rods are arranged at the corners of the base frame and two groups are arranged on one side. The float 3 is movably arranged on the sliding guide rod 2 through the power generation transmission mechanism. The wind power generation mechanism includes a sleeve seat 4, a wind blade frame 5, a wind transmission mechanism and a wind guide plate 6. The wind blade frame 5 is arranged on the upper end of the float 3 through the sleeve seat 4. The top of the float is a cylindrical structure. The sleeve seat is rotatably sleeved on the top of the float. The wind blade frame is a cylindrical structure fixed on the sleeve seat. The wind transmission mechanism is arranged in the wind blade frame 5. The wind guide plate 6 is arranged on the rear side of the wind blade frame 5, which can control the rotation of the sleeve seat so that the wind transmission mechanism always faces the wind direction.

[0023] The power generation transmission mechanism includes a transmission box 7, a transmission toothed disc 8, a transmission gear 9, a guide bin 10, an engaging gear 11, a guide groove 12 and a first generator 13. The transmission box 7 is fixedly arranged on the upper end of the sliding guide rod 2. The transmission toothed discs 8 are symmetrically arranged in the transmission box 7. The transmission gear 9 is arranged between the transmission toothed discs 8. There are two groups of transmission gears, which are respectively meshed with multiple groups of transmission toothed discs for transmission. A guide bin 10 is arranged on one side of the transmission box 7. The transmission toothed disc 8 coaxially extends into the guide bin 10 and is provided with an engaging gear 11. The guide groove 12 is arranged at the upper and lower ends of the guide bin 10. The first generator 13 is arranged on the other side of the transmission box 7. The float 3 is movably sleeved on the outside of the transmission box 7 and can fluctuate up and down with the waves.

[0024] The input end of the first generator 13 is coaxially driven with the transmission gear 9. Fixed seats 14 are arranged on the upper and lower sides inside the float 3. The lower fixed seat 14 is slidably adapted with the sliding guide rod 2. The sliding here is a sealed sliding adaptation to prevent seawater from entering the inside of the float. A transmission rack plate 15 is arranged between the two sets of fixed seats 14. The transmission rack plate has rack structures on both sides. The transmission rack plate 15 is arranged through the guide groove 12 and meshes with the meshing gears 11 on both sides for transmission. The up and down fluctuations of the float drive the transmission rack plate to move up and down, drive the meshing gear to rotate, thereby rotating the transmission toothed disc, and then driving the transmission gear to rotate and drive the first generator to generate electricity. The large gear ratio between the transmission toothed disc and the transmission gear can increase the power generation efficiency. A damping guide mechanism is also arranged between the inside of the float 3 and the transmission box 7.

[0025] The damping guide mechanism includes a guide top column 16, a lateral connecting frame 17 and an articulated damping rod 18. The guide top column 16 is fixedly arranged above the transmission box 7. The guide top column 16 passes through the upper fixed seat 14. The lateral connecting frame 17 is symmetrically arranged between the sides of the upper and lower fixed seats 14. An articulated damping rod 18 is arranged between the middle part of the lateral connecting frame 17 and the side of the transmission box 7. The articulated damping rod is connected between the transmission box and the lateral connecting frame through a hinge joint.

[0026] A limit ring 19 is fixedly provided on the upper end of the float 3, and a rolling steel ball 20 is embedded on the lower side of the sleeve seat 4. The sleeve seat 4 is sleeved and adapted with the top end of the float 3 and the lower end is in contact and rolling adaptation with the limit ring 19 through the rolling steel ball 20, thereby increasing the smoothness of rotation.

[0027] The wind transmission mechanism includes a center frame 21, a second generator 22 and wind blades 23. The center frame 21 is fixedly arranged in the wind blade frame 5, the second generator 22 is arranged at the center of the center frame 21, and the wind blades 23 are arranged at the output end of the second generator 22 away from the wind guide plate 6. The sea breeze drives the wind blades to rotate and drives the second generator to generate electricity.

[0028] An anti-corrosion cable 24 is arranged under the base frame 1, and a connecting seat 25 is arranged under the anti-corrosion cable 24. The connecting seat 25 is connected to the external submarine cable seat. The upper end of the anti-corrosion cable 24 is electrically connected to the power generation transmission mechanism and the wind power generation mechanism. The power conversion outputs of multiple groups of first generators and second generators are connected into one cable.

[0029] When the multifunctional wave energy power generation device is used, the device is transported to the sea surface where it needs to be installed, and then the connecting seat is used to connect it to the external submarine cable seat pre-deployed on the seabed. After activation, the waves drive the float to fluctuate up and down, so as to drive the transmission rack plate to move up and down, and then the transmission rack plate drives the meshing gear to rotate, so as to rotate the transmission gear plate of the coaxial rod, and then drive the transmission gear to rotate, driving the first generator to generate electricity;

[0030] When the sea wind blows towards the wind turbine, if the wind guide plate installed at the rear is offset, the wind resistance can drive the sleeve seat to rotate, so that the wind guide plate follows the wind direction, and then the wind blade frame faces the wind direction. The sea breeze then drives the wind blades to rotate, and then drives the second generator to rotate to generate electricity, which is then transmitted in parallel by the anti-corrosion cable.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
