[0002] With the urgent need to break away from the over-reliance on fossil fuels, reducing the use of traditional fossil energy, the exploration of renewable energy has become the main concern. Green energy obtained from the natural environment is considered the best choice to alleviate the current energy crisis, more than 70% of the earth's surface is covered by the ocean, which can provide a large amount of sustainable clean energy, and the wave energy has very high power density among various ocean new energies and is easy to obtain, so efficient collection of wave energy has great potential in sustainable energy conversion.

[0003] The large-scale use of current marine renewable energy is still full of challenges, and the main technical obstacles of wave energy utilization are low energy conversion efficiency and high cost and easy damage. Combined with the low wave energy density near China's sea area and the large seasonal variation, it is required that the wave energy conversion system has the characteristics of high efficiency, easy modularization and good economy, and the oscillating buoy type power generation device has become a popular field in China's current research on wave power generation devices. The PTO system and the driving conversion mode are the key to the oscillating buoy type wave energy conversion, and the efficiency of the PTO system directly determines the conversion efficiency of the oscillating buoy type wave power generation device, and the driving conversion mode determines the efficiency of the first stage energy conversion. Therefore, the key to maximizing energy conversion efficiency is to design a high-efficiency PTO with simple system structure and small energy loss in the energy conversion process and a driving conversion device.

[0004] At present, the application prospect of combining mechanical engineering with marine disciplines is very considerable. However, most of the current oscillating buoy type power generation devices cannot fully utilize the reciprocating energy of waves and ignore the positive incentive effect of the device itself in wave conversion, the generator has large fluctuation amplitude and narrow energy capture width, and once damaged, it is difficult to repair. The mechanical driving type PTO used in the present application has high energy transmission efficiency due to low friction, can fully utilize the reciprocating oscillation of waves and the relative reciprocating motion of double floating bodies under wave excitation, effectively smooth the fluctuation of generator speed to bring more stable energy collection, and has excellent capture width ratio; at the same time, combined with the magnetic coupling type driving technology, the structure has good sealing performance, high degree of modularization and easy maintenance.

[0005] Current wave energy utilization is mostly focused on ocean surface waves with a period range of 0.5-30s. In combination with the time domain, direction and spectral characteristics of wave climate in China and the effective wave height of about 2-3m and the wave train with a period of 9s along the coast of China, most of the current wave energy utilization of the float type wave energy device is limited to the water surface to the water depth of one quarter of the wavelength, and the wave energy in deeper water is not fully utilized.

[0035] The power generation process of the present application is described below:

[0036] The floating body 5 is vertically fixed and fixed in height in the sea by the mooring assembly 8, so that the floating body 5 does not fluctuate up and down with the waves. When there are waves, the oscillating float 2 on the floating body 5 will float up and down with the waves, driving the permanent magnetic coupling nut 33 magnetically attracted thereto to move up and down on the magnetic resistance motion screw 32. When the permanent magnetic coupling nut 33 moves up and down on the magnetic resistance motion screw 32, it drives the magnetic resistance motion screw 32 to rotate clockwise or counterclockwise, and this rotation is transmitted to the input shaft of the transmission assembly 6 through the motion coupling 35.

[0037] When the magnetism resistance movement screw 32 rotates clockwise, the transmission input shaft 61 in the transmission assembly 6 is transmitted through the movement coupling 35, the transmission input shaft 61 transmits clockwise rotation to the input shaft of the first one-way overrunning clutch 66, at this time the input shaft of the first one-way overrunning clutch 66 will drive the transmission input shaft 62 to rotate clockwise, the transmission input shaft 62 will drive the third transmission gear 64 to rotate counterclockwise, the third transmission gear 64 will drive the input shaft of the second one-way overrunning clutch 67 to rotate counterclockwise, due to the characteristics of the one-way overrunning clutch, the clockwise rotation of the input shaft of the first one-way overrunning clutch 66 will be output from the output shaft, and the counterclockwise rotation of the input shaft of the second one-way overrunning clutch 67 will be blocked, the output shaft of the first one-way overrunning clutch 66 will rotate clockwise, and the second transmission gear 63 will also rotate clockwise, the second transmission gear 63 drives the transmission output shaft 68 to rotate counterclockwise through the tooth belt of the transmission output shaft 68, and drives the fourth transmission gear 65 to rotate clockwise, due to the characteristics of the one-way overrunning clutch, the rotation of the output shaft cannot be transmitted back to the input shaft end, so the second one-way overrunning clutch 67 part will not appear the gear jamming caused by the input and output different directions, the transmission output shaft 68 drives the power generation input shaft 71 to rotate counterclockwise, the power generation input shaft 71 drives the intermediate transmission gear to rotate clockwise, and the intermediate transmission gear drives the input shaft of the generator to rotate counterclockwise to realize power generation.

[0038] When the magnetism resistance movement screw 32 rotates anticlockwise, the movement is transmitted to the transmission input shaft 61 in the transmission assembly 6 through the movement coupling 35, the transmission input shaft 61 transmits the anticlockwise rotation to the input shaft of the first one-way overrunning clutch 66, at this time the input shaft of the first one-way overrunning clutch 66 will drive the transmission input shaft 62 to rotate anticlockwise, the transmission input shaft 62 will drive the third transmission gear 64 to rotate clockwise, the third transmission gear 64 will drive the input shaft of the second one-way overrunning clutch 67 to rotate clockwise, due to the characteristics of the one-way overrunning clutch, the clockwise rotation of the input shaft of the second one-way overrunning clutch 67 will be output from the output shaft, and the anticlockwise rotation of the input shaft of the first one-way overrunning clutch 66 will be blocked, the output shaft of the second one-way overrunning clutch 67 will rotate clockwise, and the fourth transmission gear 65 will also rotate clockwise, the fourth transmission gear 65 drives the transmission output shaft 68 to rotate anticlockwise through the tooth belt of the transmission output shaft 68, and drives the second transmission gear 63 to rotate clockwise, due to the characteristics of the one-way overrunning clutch, the rotation of the output shaft cannot be transmitted back to the input shaft end, so the first one-way overrunning clutch 66 part will not appear the gear jamming caused by the input and output in different directions, the transmission output shaft 68 drives the power generation input shaft 71 to rotate anticlockwise, the power generation input shaft 71 drives the intermediate transmission gear to rotate clockwise, and the intermediate transmission gear drives the input shaft of the generator to rotate anticlockwise to realize power generation. The working modes of the upper and lower transmission assemblies 6 are the same, and both can change the input of different rotation directions into the output of the same direction. In order to avoid the vibration of the oscillating float 2 with a large frequency, the excess rotation is stored through the energy storage spring 69, and such rotation storage can also be released when the oscillating float 2 has a small frequency, which plays a role in reasonable absorption and utilization of wave energy.

[0039] As the oscillating float 2 will float up and down with the wave, a sea current will flow along the axis of the float 5, and the wave energy below the sea level will also be generated, the annular damping disc 4 can well absorb the energy generated by the sea current and the wave energy. Taking the absorption of the energy generated by the sea current as an example, when the oscillating float 2 rises, the rising sea current will drive the damping block 44 of the annular damping disc 4 to move upward, and the damping block 44 drives the outer ring support ring 41 to move upward. Since the middle ring support ring 42 is fixed by the support rod 47 and will not move up and down, the support sleeve 48 sleeved on the middle ring support ring 42 can rotate on the inner ring support ring 43. The outer ring connecting rod, the support sleeve 48 and the inner ring connecting rod form a lever-like structure with the support sleeve 48 as the fulcrum, when one end of the outer ring connecting rod moves upward, the other end of the inner ring connecting rod will move downward through the rotation of the support sleeve 48. When the outer ring support ring 41 moves upward, one end of the outer ring connecting rod connected with it will also move upward, and one end of the inner ring connecting rod will move downward, and the inner ring support ring 43 connected with the inner ring connecting rod will move downward, and the permanent magnet coupling nut 33 magnetically attracted to the inner ring support ring 43 will move downward; when the oscillating float 2 descends, the sea current will descend, the outer ring support ring 41 moves downward, the inner ring support ring 43 moves upward, and the permanent magnet coupling nut 33 magnetically attracted to the inner ring support ring 43 moves upward, so as to realize the absorption of the energy generated by the sea current.

[0040] Although the embodiments of the present application have been described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
