In some embodiments, as shown in fig. 1 and 2, the in-water cleaning apparatus 100 further includes a retraction device 13 movably connected to the cleaning main body 10 and the wave energy conversion power source mechanism 12, when the retraction device 13 moves to be in a first state relative to the cleaning main body 10, the wave energy conversion power source mechanism 12 is driven to be in an open state relative to the cleaning main body 10, and when the retraction device 13 moves to be in a second state relative to the cleaning main body 10, the wave energy conversion power source mechanism 12 is driven to be in a gathered state relative to the cleaning main body 10. It will be appreciated that when the retraction device 13 moves to a first state relative to the cleaning main body 10, and the wave energy conversion power source mechanism 12 is in an open state relative to the cleaning main body 10, the wave energy conversion power source mechanism 12 is in a stable working state and position, and when severe weather such as hurricane or typhoon is encountered, the retraction device 13 is started and moves to a second state relative to the cleaning main body 10 because the wave energy conversion power source mechanism 12 is easily damaged by hurricane or typhoon, so that the wave energy conversion power source mechanism 12 is driven to be in a gathering state relative to the cleaning main body 10, thereby effectively avoiding damage by hurricane or typhoon, and protecting the integral structural integrity of the underwater cleaning device 100.

In some embodiments, as shown in fig. 1,2, 13 and 14, the retraction device 13 includes a fixed body 131, a first crank 132, a linkage rod 133 and a first driving device; the fixing body 131 comprises an inner ring and an outer ring rotationally connected with the inner ring, the inner ring is sleeved on the first rotating member 121, the first crank 132 is hinged to the outer ring, the first crank 132 can be fixed on the first rotating member 121 through the matching of the inner ring and the outer ring, and the first crank 132 can be prevented from interfering the rotation of the first rotating member 121, wherein the fixing body 131 can be of a bearing structure and has good rotation performance. One end of the first crank 132, which is far away from the outer ring, is hinged with the linkage rod 133, the other end of the linkage rod 133 is hinged with the cleaning main body 10, the output end of the first driving device is connected with the first crank 132, the first driving device drives the first crank 132 to be in a first state when being coaxial with the linkage rod 133, and the first driving device drives the first crank 132 to be in a second state when being not coaxial with the linkage rod 133. It will be appreciated that in normal operation, the first crank 132 and the linkage rod 133 are in a straight line, the transmission angle γ of the first crank 132 of the retraction device 13 is 0 ° and the mechanism is at the dead point position, the retraction device 13 supports the wave energy conversion power source mechanism 12 to open the wave energy conversion power source mechanism 12 relative to the cleaning main body 10, and at this time, the retraction device 13 will maintain the open state regardless of the thrust of the first rotating member 121 by the sea wave, and the wave energy conversion power source mechanism 12 is kept open and in a stable operation position relative to the cleaning main body 10. When the user encounters severe weather such as hurricane or typhoon, the retraction device 13 is started, the first crank 132 is driven by the first driving device to rotate anticlockwise, so that the first rotating member 121 is tightened, and the wave energy conversion power source mechanism 12 is driven to be in a gathering state relative to the cleaning main body 10, thereby effectively avoiding damage caused by hurricane or typhoon and protecting the integral structural integrity of the underwater cleaning device 100.

When one sea wave passes, the wave crest and the wave trough of the sea wave are exchanged, at this time, the first floating member 122 is reversed, the pawl slides through the ratchet groove of the first floating member 122 and does not drive the ratchet wheel to rotate, at this time, the first rotating member 121 does not rotate. Repeatedly, the in-water cleaning apparatus 100 can realize intermittent unidirectional rotation of the first rotating member 121 by utilizing the fluctuation of the sea wave. By arranging a reasonable number of the first floating members 122, the first rotating member 121 can be driven to rotate along one direction once by ocean waves, the inversion of the first rotating member 121 can be effectively avoided, and the conversion of ocean wave energy into mechanical energy is completed. Furthermore, the cooperation of the plurality of first floating members 122 enables efficient rotation of the first rotating member 121: the unidirectional rotation efficiency of the first rotation member 121 is greatly improved.

In contrast, when the small arc end of the first floating member 122 is positioned at the wave crest and the large arc end is positioned at the wave trough, the height difference of the wave crest and the wave trough can push the first floating member 122 to reversely rotate.

As can be appreciated, the movement of the movable member 33 is transmitted to the connecting rod 341, and the connecting rod 341 transmits the movement to the second crank 342, thereby pushing the second crank 342 to rotate, and the second crank 342 is coaxially connected with the first gear 343, so that the first gear 343 rotates in synchronization with the second crank 342. And the first gear 343 and the second gear 344 are engaged, so that the first gear 343 and the second gear 344 are rotated synchronously, and the second gear 344 drives the third rotating member 32 to rotate. This converts the horizontal motion at sea level into rotation of the third rotating member 32, and changes the motion state so that the wave energy in the ocean energy is smoothly converted into the rotational driving force required when the third rotating member 32 adsorbs the oil stain. In other embodiments, the transmission device 34 may be other devices capable of converting horizontal motion into rotational motion, which is not particularly limited herein.

In some embodiments, as shown in fig. 8, the underwater oil dirt collection mechanism 3 further includes a second unidirectional motion 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 motion device 37. It will be appreciated that when the in-water oil and dirt collecting mechanism 3 is used for marine oil and dirt salvage, the second float member 35 is normally pushed by sea waves to move forward or backward along its length direction, and the third rotary member 32 can be rotated only in the direction of orientation by the connection between the second crank 342 and the first gear 343 via the second unidirectional movement device 37, the second unidirectional movement device 37 being connected to prevent the third rotary member 32 from reversing. In addition, the third rotating member 32 can only rotate in the directional direction, so that the scraping member 312 can scrape off the oil dirt adsorbed on the oil suction layer 321, and the oil dirt flows into the oil storage cavity 311 for storage, and the phenomenon that the oil dirt scraped off by the scraping member 312 flows out to the sea surface again due to the reverse rotation of the third rotating member 32 is avoided. The second unidirectional movement device 37 may be a ratchet mechanism or other device capable of unidirectional rotation of the third rotation member 32, and is not particularly limited herein.

In some embodiments, a second float 35, a transmission 34, and a third rotary member 32 cooperate to form an oil collection assembly; the in-water oil-dirt collecting mechanism 3 comprises a plurality of oil dirt collecting components, and the oil dirt collecting components are arranged on the body 11 in a dispersing mode. It can be understood that each greasy dirt collecting assembly can adsorb the greasy dirt on the sea surface, and a plurality of greasy dirt collecting assemblies cooperate to increase the area for adsorbing the greasy dirt, so that the efficiency for adsorbing the greasy dirt is improved.

In some embodiments, the body 11 is in a circular disk configuration, and each of the oil collection assemblies is disposed along a radial direction of the body 11. So that each oil stain collecting component is matched to form a fan-shaped structure to adapt to the wave fluctuation state of the sea surface, and the mutual interference of each oil stain collecting component is effectively avoided to influence the oil stain adsorption effect.

In some embodiments, as shown in fig. 10, the underwater oil dirt collection mechanism 3 further includes a universal joint 36, and two adjacent second floating members 35 are movably connected by the universal joint 36. It will be appreciated that the waves in the ocean continuously fluctuate and drive the second float 35 to move up and down, left and right and back and forth, the direction of movement is uncertain, and the relative movement of the plurality of oil dirt collecting assemblies is also uncertain, so that the plurality of oil dirt collecting assemblies are difficult to always move synchronously with each other, and have relative movement. Therefore, the plurality of oil stain collecting assemblies are utilized to respectively convert wave energy into driving force of the underwater oil stain collecting mechanism 3 under the acting force of sea waves, in order to enable the plurality of second floating members 35 to move smoothly relative to each other, the adjacent two second floating members 35 are prevented from forming motion interference, the adjacent two second floating members 35 are movably connected through the universal joint 36, the universal joint 36 can enable the second floating members 35 to be flexibly connected, and each second floating member can independently move and better fit the wave fluctuation motion. It should be further noted that, when the third rotating member 32 is driven to rotate by the driving rack 354 and the driven gear 332, in order to improve the tightness of the coupling 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, so as to avoid the influence of the mutual disengagement between the driving rack 354 and the driven gear 332.

The above examples are also not an exhaustive list based on the invention, and there may be a number of other embodiments not listed. Any substitutions and modifications made without departing from the spirit of the invention are within the scope of the invention.
