With the development of technology, the functions of ocean monitoring buoys continue to expand, integrating more sophisticated electronic equipment. The efficient operation of these devices cannot be achieved without stable power supply. However, buoys are usually deployed in remote offshore areas, and the distribution of buoys is sparse.

At the same time, under the action of the tidal current, the blades 606 rotate and drive the movable shaft 605 to rotate, thereby making the tidal current generator 603 generate electricity and collect energy, further improving the power generation capacity and ensuring that the buoy monitoring equipment has sufficient power to operate.

[0042] The working principle of the embodiment is as follows:

[0043] When the floating block 5 rises with the wave, the first movable rod 302 and the second movable rod 308 in the same movable frame unit rotate by a corresponding amplitude, the second movable rod 308 is in a fixed connection state with the driving shaft 204, thereby driving the driving shaft 204 to rotate, the first gear 203 is internally provided with a cavity 226, and the cavity 226 is internally provided with a ratchet mechanism, the driving shaft 204 rotates to drive the ratchet disc 224 to rotate, at this time, the rotation direction is indicated as positive rotation, the spring pawl 222 plays a role in positive rotation, is clamped with the tooth groove 223, and drives the first gear 203 to rotate together, the first gear 203 drives the second gear 205 connected in mesh to rotate, since the diameter of the second gear 205 is smaller than that of the first gear 203, the rotation speed is increased, the second gear 205 drives the third gear 207 coaxially connected therewith to rotate synchronously, the third gear 207 drives the fourth gear 202 connected in mesh therewith to rotate, since the diameter of the fourth gear 202 is smaller than that of the third gear 207, the rotation speed is increased. The rotation of the fourth gear 202 drives the gear ring 211 to rotate through the rotation frame 212 connected coaxially, since the four-stage gear speed increasing structure is arranged, the rotation speed of the gear ring 211 is increased, the rotation of the gear ring 211 drives the fifth gear 209 connected in mesh with the outer teeth of the gear ring 211 to rotate, and the fifth gear 209 drives the wave energy generator 208 to generate electricity. At the same time, the rotation of the gear ring 211 drives the sixth gear 220 connected in mesh with the inner teeth of the gear ring 211 to rotate, the sixth gear 220 drives the first transmission gear 218 connected coaxially therewith to rotate, the first transmission gear 218 and the transmission tooth belt 219 drive the second transmission gear 213 to rotate, the second transmission gear 213 drives the transmission shaft 214 fixedly connected in the middle to rotate, and the rotation of the transmission shaft 214 drives the volute spring 216 to tighten, thereby storing energy and improving the energy recovery efficiency. When the floating block 5 descends with the wave, the driving shaft 204 reverses, at this time, the ratchet disc 224 reverses, the spring pawl 222 cannot play a role, does not drive the first gear 203 to rotate, and does not transmit energy, thereby relaxing the volute spring 216 after the floating frame 3 resets, driving the transmission shaft 214 to rotate in the reverse direction, and driving the gear ring 211 to rotate in the reverse direction through the reverse movement of the second transmission gear 213, the transmission tooth belt 219, the first transmission gear 218 and the sixth gear 220, the gear ring 211 drives the fifth gear 209 connected in mesh with the outer teeth thereof to rotate in the reverse direction, and makes the wave energy generator 208 continue to generate electricity, at this time, the first gear 203 rotates, but does not act on the ratchet disc 224. When the floating block 5 at the rear end rises with the wave, the third movable rod 305 and the fourth movable rod 310 on the same movable frame unit also swing, the third movable rod 305 rotates around the first movable rod 302, and the fourth movable rod 310 is in a fixed connection state with the driving shaft 204 at the rear end, thereby driving the driving shaft 204 to rotate, and the subsequent movement process is the same as that of the wave energy generation module 2 at the front end.

[0044] The tidal current energy generation module 6 is installed at the bottom end of the connecting frame 4 through the fixing frame 601, the bearing frame 602 rotates with the change of the tidal current direction, drives the fixed connection of the fairing 604 to rotate, under the action of the tidal current, the blade 606 drives the movable shaft 605 to rotate, the top end of the movable shaft 605 is connected with the tidal current generator 603, so that the tidal current generator 603 generates electricity.
