With the development of science and technology, the functions of ocean monitoring buoys continue to expand, integrating more sophisticated electronic equipment, and the efficient operation of these devices is inseparable from a stable power supply. However, buoys are usually deployed in waters far from the shore, sparsely distributed, and the marine environment is complex and changeable.

The fourth disc frame 309 is connected to the driving shaft 204 of the wave energy power generation module 2 to ensure the stable rotation of the internal structure of the wave energy power generation module 2. The first disc frame 301 and the second disc frame 307 located on different movable frames and adjacent to each other are connected by a connecting rod and are arranged back to back at the second end of the support rod 306.

[0037] The wave energy power generation module 2 includes a wave energy frame 201, a drive shaft 204, a first gear 203, a second gear 205, a third gear 207, a fourth gear 202, a rotating frame 212, a gear ring 211, a fifth gear 209 and a wave energy generator 208. The diameter of the first gear 203 is greater than the diameter of the second gear 205, and the diameter of the third gear 207 is greater than the diameter of the fourth gear 202, thereby forming a four-stage speed increase structure. The drive shaft 204 is installed at one end of the wave energy frame 201, and the drive shaft 204 is used to connect the second disc frame 3 07, so that the driving shaft 204 can rotate under the drive of the movable frame unit, the driving shaft 204 can extend into the wave energy frame 201 and be coaxially connected to the first gear 203, and the driving shaft 204 drives the first gear 203 to rotate when rotating, and the outer periphery of the first gear 203 meshes with the outer periphery of the second gear 205, thereby driving the second gear 205 to rotate, and the second gear 205 is coaxially connected with the third gear 207 through the connecting shaft 206, thereby driving the third gear 207 to rotate, and the outer periphery of the third gear 207 meshes with the outer periphery of the fourth gear 202 , thereby driving the fourth gear 202 to rotate, and the rotation speed is increased through a four-stage speed increasing structure. One side of the fourth gear 202 is coaxially connected to the middle of the rotating frame 212, thereby driving the rotating frame 212 to rotate, and a plurality of legs are installed in the circumference of the rotating frame 212, each leg extends in a direction away from the plane where the fourth gear 202 is located, and each leg is installed on the end face of the gear ring 211, so that the rotating frame 212 drives the gear ring 211 to rotate, and the inner ring and the outer ring of the gear ring 211 are provided with teeth, and the gear ring 211 is rotatably connected to the inner ring of the wave energy frame 201 , ensuring the stability of the rotation of the gear ring 211, multiple fifth gears 209 are respectively engaged with the outer circumference of the gear ring 211, and can rotate with the rotation of the gear ring 211, and multiple fifth gears 209 correspond to multiple wave energy generators 208 one by one, and the output shaft of the wave energy generator 208 is coaxially connected to the fifth gear 209, and then the rotation of the fifth gear 209 is converted into electrical energy storage through the wave energy generator 208 for use by the buoy monitoring equipment, and each wave energy generator 208 is installed on the wave energy frame 201 to improve the structural stability.

[0038] The wave energy power generation module 2 also includes an energy storage mechanism 210, which includes a sixth gear 220, a first transmission gear 218, a second transmission gear 213, a cover 215, a volute spring 216 and a spring box 217. The outer periphery of the sixth gear 220 is meshed with the inner ring of the gear ring 211, so that when the gear ring 211 rotates, the sixth gear 220 can be driven to rotate. The sixth gear 220 is coaxially connected to the first transmission gear 218 and can drive the first transmission gear 218 to rotate. The spring box 217 is connected to the inner side of the wave energy frame 201, and a cover 215 is installed on the top of the spring box 217. A positioning plate 221 is installed on the top of the cover 215. The sixth gear 220 is rotatably connected to the positioning plate 221. The transmission shaft 214 passes through the positioning plate 221 and the transmission shaft 214 in sequence. The cover 215 and the volute spring 216 are installed in the spring box 217, and the volute springs 216 are preferably three, and the three volute springs 216 are separated by a separation ring and a bearing, one end of the volute spring 216 is connected to the inner wall of the spring box 217, and the other end of the volute spring 216 is connected to the outer periphery of the transmission shaft 214, and then when the floating frame 3 rotates with the rise of waves and gradually drives the gear ring 211 to rotate, the gear ring 211 gradually drives the transmission shaft 214 to rotate and tightens the volute spring 216 to achieve energy storage. When the floating frame 3 rotates with the descending of waves, due to the design of the ratchet mechanism at the back, the driving shaft 204 cannot transmit energy to the first gear 203, thereby releasing the volute spring 216 and driving the wave energy generator 208 to generate electricity in the reverse direction. Therefore, electricity can be generated during the rising and falling processes of the waves, thereby realizing continuous and stable power generation of the wave energy power generation module 2, increasing the power generation, and facilitating the long-term operation of the buoy monitoring equipment. In addition, the four-stage speed increasing structure and the setting of the volute spring 216 are used to improve the power generation and power generation efficiency.

[0039] The bottom end of the transmission shaft 214 is connected to a T-shaped shaft 227, and the T-shaped shaft 227 is adapted to the T-shaped slot provided at the bottom end of the rotating frame 212. The T-shaped shaft 227 is rotatably connected to the T-shaped slot, and then the position of the rotating frame 212 is limited accordingly through the cooperation between the T-shaped shaft 227 and the T-shaped slot, so that the rotating frame 212 cannot slide but can only rotate, thereby ensuring the effective engagement of the gear ring 211 with each gear.

[0040] A cavity 226 is provided inside the first gear 203, and a ratchet mechanism is installed in the cavity 226. The ratchet mechanism includes a spring pawl 222, a tooth groove 223 and a ratchet plate 224.

A plurality of tooth grooves 223 are circumferentially arranged on the inner ring of the first gear 203 and can cooperate with the spring pawl 222. A limiting ring 225 is coaxially provided on the inner wall of the cavity 226, and a limiting groove is provided on the outer periphery of the ratchet plate 224. The limiting ring 225 can be embedded in the limiting groove and rotate with the limiting groove. When the floating frame 3 follows the wave to rise, the driving shaft 204 rotates and drives the ratchet disk 224 to rotate forward, the spring pawl 222 engages with the tooth groove 223 and drives the first gear 203 to rotate, and the first gear 203 transmits kinetic energy to the gear ring 211 and tightens the scroll spring 216. When the floating frame 3 follows the wave to fall, the spring pawl 222 does not engage with the tooth groove 223, and the first gear 203 cannot rotate. After the floating frame 3 is reset, the scroll spring 216 is also reset and drives the gear ring 211 to rotate, so as to output energy to the wave energy generator 208. At this time, the first gear 203 rotates, but does not act on the ratchet disk 224. This setting is to ensure that when the corresponding energy is output forward and reverse, the corresponding movements do not interfere with each other.

Those skilled in the art can also adaptively adjust the number thereof according to actual needs. The tidal energy power generation module 6 includes a receiving frame 602, a tidal energy generator 603, a guide cover 604, a movable shaft 605 and blades 606. The upper end of the receiving frame 602 is rotatably installed at the middle lower end of the fixing frame 601, and two guide covers 604 are symmetrically installed at both ends of the receiving frame 602, and both guide covers 604 are arc-shaped plates, and the openings of the two guide covers 604 are arranged opposite to each other, and the guide covers 604 extend in the vertical direction, each A movable shaft 605 is installed in the fairing 604, and the movable shaft 605 extends in the vertical direction. The movable shaft 605 can only rotate and does not move up and down. The output shaft of the tidal energy generator 603 is coaxially connected to one end of the movable shaft 605. The tidal energy generator 603 and the wave energy generator 208 are both provided with a waterproof structure. The outer periphery of each movable shaft 605 is connected to a plurality of blades 606. The blades 606 on the outer periphery of each movable shaft 605 are preferably three, and the blades 606 are located in the fairing 604. The receiving frame 602 can rotate with the direction of the tide. At the same time, under the action of the tide, the blades 606 rotate and drive the movable shaft 605 to rotate, thereby enabling the tidal energy generator 603 to generate electricity and collect energy, further increasing the power generation, and ensuring that the buoy monitoring equipment has sufficient power to operate.

[0042] The working principle of this embodiment is:

[0043] When the buoy 5 rises with the waves, the first movable rod 302 and the second movable rod 308 in the same movable frame unit rotate by a corresponding amplitude, and the second movable rod 308 is fixedly connected to the driving shaft 204, thereby driving the driving shaft 204 to rotate. A cavity 226 is provided inside the first gear 203, and a ratchet mechanism is provided inside the cavity 226. The rotation of the driving shaft 204 will drive the ratchet plate 224 to rotate. At this time, the rotation direction is represented as forward rotation. During forward rotation, the spring ratchet 222 plays a role, and its engagement with the tooth groove 223 will drive the first gear 203 to rotate together. The first gear 203 drives the second gear 205 meshing with it 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 thereto to rotate synchronously. The third gear 207 drives the fourth gear 202 meshing with it 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 will drive the gear ring 211 to rotate through the coaxially connected rotating frame 212. Due to the setting of the four-stage gear speed-increasing structure, the rotation speed of the gear ring 211 is increased. The rotation of the gear ring 211 will drive the fifth gear 209 meshing with its external teeth 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 will drive the sixth gear 220 meshing with its internal teeth to rotate, and the sixth gear 220 drives the first transmission gear 218 coaxially connected to rotate, and the second transmission gear 213 is driven to rotate through the transmission action of the first transmission gear 218 and the transmission toothed belt 219. The second transmission gear 213 drives the transmission shaft 214 fixedly connected to the middle thereof to rotate together, and the rotation of the transmission shaft 214 will drive the volute spring 216 to tighten, thereby storing energy and improving the energy recovery efficiency. When the buoy 5 descends with the waves, the drive shaft 204 reverses, and the ratchet plate 224 reverses at this time, and the spring pawl 222 cannot function, and does not drive the first gear 203 to rotate and transfer energy. Therefore, after the floating frame 3 is reset, the volute spring 216 relaxes, drives the transmission shaft 214 to rotate in the opposite direction, and drives the gear ring 211 to rotate in the opposite direction through the reverse movement of the second transmission gear 213, the transmission toothed belt 219, the first transmission gear 218 and the sixth gear 220. The gear ring 211 drives the fifth gear 209 meshing with its external teeth to rotate in the opposite direction, and enables the wave energy generator 208 to continue to generate electricity. At this time, the first gear 203 rotates, but does not act on the ratchet plate 224. When the buoy 5 at the rear end rises with the waves, 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 fixedly connected to 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 power generation module 2 at the front end.

[0044] The tidal energy power generation module 6 is installed at the bottom end of the connecting frame 4 through the fixing frame 601. The receiving frame 602 rotates with the change of the tidal direction, driving the deflector 604 fixedly connected to it to rotate. Under the action of the tidal current, the blades 606 will drive the movable shaft 605 to rotate. The top end of the movable shaft 605 is connected to the tidal energy generator 603, so that the tidal energy generator 603 can generate electricity.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
