When a wave passes, the wave crest and the wave trough of the wave are exchanged, at this time, the first floating piece 122 rotates reversely, the pawl slides through the ratchet groove of the first floating piece 122, the ratchet is not driven to rotate, and at this time, the first rotating piece 121 does not rotate.

In some embodiments, as shown in fig. 8, the body 11 has an oil storage cavity 311 inside, the underwater oil collecting mechanism 3 further includes a scraper 312 disposed on the body 11, the scraper 312 is in contact with the oil absorption layer 321, and the third rotating element 32 can rotate relative to the scraper 312, and an oil inlet of the oil storage cavity 311 is located below a contact position of the scraper 312 and the oil absorption layer 321. Understandably, in the rotating process of the third rotating member 32, the oil absorption layer 321 is driven to rotate and continuously absorb the oil stains on the sea surface, when the third rotating member 32 drives the oil absorption layer 321 with the oil stains absorbed thereon to rotate to the position of the scraping member 312, the scraping member 312 scrapes the oil stains absorbed on the oil absorption layer 321, and the oil stains flow into the oil storage cavity 311 to be stored, so that the oil absorption layer 321 can continuously absorb the oil stains on the sea surface, and the oil absorption layer 321 is effectively prevented from absorbing too much oil stains to influence the further oil stain absorption effect.

In some embodiments, as shown in fig. 8, the transmission 34 includes a connecting rod 341, a second crank 342, and a first gear 343 and a second gear 344 disposed in meshing engagement; the opposite ends of the connecting rod 341 are respectively hinged to the movable member 33 and the second crank 342, the other end of the second crank 342 away from the connecting rod 341 is connected to the first gear 343, and the output end of the second gear 344 is connected to the third rotating member 32. It will be understood that the movement of the movable member 33 is transmitted to the connecting rod 341, the connecting rod 341 transmits the movement to the second crank 342, so as to push the second crank 342 to rotate, the second crank 342 is coaxially connected with the first gear 343, and therefore, the first gear 343 and the second crank 342 rotate synchronously. And the first gear 343 is engaged with the second gear 344, so that the first gear 343 and the second gear 344 rotate synchronously, and the second gear 344 drives the third rotating member 32 to rotate. Therefore, the horizontal movement at sea level can be converted into the rotation of the third rotating member 32, and the movement state is changed, so that the wave energy in the ocean energy can be smoothly converted into the rotation driving force required by the third rotating member 32 when oil stains are absorbed. It should be noted that, in other embodiments, the transmission device 34 may also be other devices capable of converting a horizontal motion into a rotational motion, and is not limited herein.

In some embodiments, as shown in fig. 8, the underwater oil collecting mechanism 3 further includes a second unidirectional moving device 37 disposed between the second crank 342 and the first gear 343, and the second crank 342 drives the first gear 343 to rotate unidirectionally through the second unidirectional moving device 37. It will be appreciated that when the underwater oil collecting mechanism 3 is used for marine oil fishing, the second floating member 35 can be driven by sea waves to move forward or backward in the longitudinal direction thereof under normal conditions, and the second unidirectional movement device 37 is connected between the second crank 342 and the first gear 343, so that the third rotating member 32 can be prevented from rotating reversely, so that the third rotating member 32 can only rotate in a directional direction. In addition, the third rotating member 32 can only rotate in a directional direction, so that the oil stain absorbed on the oil absorption layer 321 can be scraped by the scraping member 312, and the oil stain flows into the oil storage cavity 311 for storage, thereby preventing the oil stain scraped by the scraping member 312 from flowing out to the sea surface again due to the reverse rotation of the third rotating member 32. The second unidirectional moving device 37 may be a ratchet mechanism or other device capable of unidirectional rotation of the third rotating element 32, and is not limited herein.

In some embodiments, a second float 35, a transmission 34 and a third rotating member 32 cooperate to form a grease collection assembly; the aquatic oil contamination collecting mechanism 3 comprises a plurality of oil contamination collecting assemblies, and each oil contamination collecting assembly is dispersedly arranged on the body 11. Understandably, each greasy dirt collecting assembly can adsorb sea surface greasy dirt, and the area of adsorbing the greasy dirt can be increased by the cooperation of a plurality of greasy dirt collecting assemblies, so that the efficiency of adsorbing the greasy dirt is improved.

In some embodiments, the body 11 is a circular disk structure, and each oil collecting assembly is disposed along a radial direction of the body 11. So that each greasy dirt collection subassembly cooperation forms fan-shaped structure to the wave fluctuation state of adaptation sea effectively avoids each greasy dirt collection subassembly mutual interference to influence greasy dirt adsorption effect.

In some embodiments, as shown in fig. 10, the underwater oil collecting mechanism 3 further includes a universal joint 36, and two adjacent second floating members 35 are movably connected by the universal joint 36. Understandably, the second floating member 35 can be driven by the continuous fluctuation of the waves in the ocean to move up and down, left and right, and back and forth, the moving direction is uncertain, the relative movement of the oil collecting assemblies is uncertain, and the oil collecting assemblies are difficult to move synchronously all the time and have relative movement. Consequently utilize a plurality of greasy dirt to collect the subassembly and convert wave energy into the drive power of this aquatic greasy dirt collection mechanism 3 respectively under the effort of wave, in order to make the relative motion that can be smooth between a plurality of second floats 35, avoid forming the motion interference, through universal joint 36 swing joint between two adjacent second floats 35, universal joint 36 can make each second float flexible connection between the piece 35, independent motion separately, and laminate the wave heave motion better. It should be noted that, when the third rotating member 32 is rotated by the driving rack 354 and the driven gear 332, in order to improve the tightness of the fit between the driving rack 354 and the driven gear 332, the universal joint 36 and the body 11 may be connected by a connecting member, so that the relative position between the second floating member 35 and the body 11 is fixed, and the driving rack 354 and the driven gear 332 are prevented from being disengaged from each other to affect the transmission effect.

The above examples are not intended to be exhaustive of the invention and there may be many other embodiments not listed. Any alterations and modifications without departing from the spirit of the invention are within the scope of the invention.
