[0021] Example 1 like Figures 1-7 As shown, a suction-type harvesting device for sea cucumber harvesting includes an underwater robot 1, a camera 2, a driver 3, a storage tank 4, and a suction device 5. It also includes a rotating plate 11, which is rotatably mounted on the underwater robot 1 via a first rotating shaft 13 driven by a first motor 12. A suction tube 15 is movably mounted through the rotating plate 11, with a suction nozzle 7 connected to the first end of the suction tube 15. A lifting assembly 8 for driving the suction tube 15 to rise and fall is provided on the rotating plate 11. A hose 10 is connected at one end to the second end of the suction tube 15 and at the other end to the suction device 5 via a main pipe 6. A cleaning assembly 9 is provided inside the storage tank 4.

[0022] Specifically, after the underwater robot 1 moves to the target sea area via the driver 3, the first motor 12 drives the first rotating shaft 13 to rotate, causing the rotating plate 11 to rotate horizontally. At the same time, the lifting assembly 8 drives the suction tube 15 to rise and fall vertically, realizing the three-dimensional precise positioning of the sea cucumber by the suction nozzle 7. The suction device 5 delivers negative pressure to the suction tube 15 through the main pipe 6, the hose 10 and the rotary joint 14. After the suction nozzle 7 adsorbs the sea cucumber, the seawater carries the sea cucumber through the hose 10 into the storage tank 4. The entire process requires no manual contact. The overall structure and operation steps are simple, enabling automated collection of sea cucumbers. At the same time, the position of the suction nozzle 7 can be precisely adjusted, improving the versatility of the device.

[0023] It should be noted that, in this embodiment, the structure, installation position and working principle of the underwater robot 1, camera 2, driver 3, storage tank 4 and suction device 5 can be referred to the published document with patent announcement number CN117918316B, which is prior art and will not be described here.

[0024] In this embodiment, as Figures 1 to 7As shown, the cleaning assembly 9 includes a fixed shaft 91, which is disposed inside the storage tank 4. Multiple cleaning rods 92 are fixedly mounted on the fixed shaft 91 circumferentially. The cleaning rods 92 are slidably disposed inside the storage tank 4. A rack 93 passes through and slidably disposed on the storage tank 4. The rack 93 is fixedly connected to the cleaning rods 92. The underwater robot 1 is provided with a moving mechanism 94 that drives the rack 93 to move. A fixed plate 16 is fixedly mounted on the underwater robot 1. The rack 93 passes through and movably disposed on the fixed plate 16. The moving mechanism 94 includes a drive gear 943 sleeved on a first rotating shaft 13 and a driven gear 941 rotatably disposed on the fixed plate 16 via a second rotating shaft 942. 41 meshes with rack 93 and drive gear 943. Specifically, during the process of the first motor 12 driving the rotating plate 11 to move back and forth, the first rotating shaft 13 rotates, and the drive gear 943 sleeved on the first rotating shaft 13 rotates accordingly. The drive gear 943 meshes with the driven gear 941, driving the driven gear 941 to rotate. The driven gear 941 then meshes with rack 93, thereby pushing rack 93 to slide on fixed plate 16, realizing the movement of cleaning rod 92. The cleaning component 9 can stir the sea cucumbers accumulated in storage tank 4, disperse the impurities in storage tank 4 and between the sea cucumbers, making it easier to discharge the impurities in storage tank 4 to the outside along the water flow, thus improving the cleaning effect of storage tank 4.

[0025] In this embodiment, as Figures 4 to 7 As shown, a slider 17 is fixedly installed on the cleaning rod 92, and a groove 18 for the slider 17 to slide is provided inside the storage tank 4.

[0026] In this embodiment, as Figure 5 and Figure 6 As shown, the diameter of the driving gear 943 is larger than the diameter of the driven gear 941.

[0027] In this embodiment, as Figures 1 to 4 As shown, the lifting assembly 8 includes a worm gear 83, which is rotatably mounted on a rotating plate 11. The suction tube 15 passes through and is threadedly connected to the worm gear 83. A worm 82, which meshes with the worm gear 83, is rotatably mounted on the rotating plate 11. The worm 82 is driven by a second motor 81. A guide rod 84 passes through and is movably mounted on the rotating plate 11. The guide rod 84 is fixedly connected to the suction nozzle 7. Specifically, through the arrangement of the worm gear 83 and the worm 82, the lifting height of the suction tube 15 can be precisely controlled, enabling the suction nozzle 7 to accurately suck up the sea cucumber. At the same time, the arrangement of the guide rod 84 further ensures the stability and accuracy of the lifting of the suction tube 15, preventing the suction nozzle 7 from deviating or rotating during the lifting process, thereby improving the success rate and accuracy of harvesting.

[0028] In this embodiment, as Figures 1 to 4 As shown, the hose 10 and the suction tube 15 are connected by a rotary joint 14.

[0029] When using this utility model: By activating the underwater robot 1 and controlling it to move to the target sea area via the actuator 3, and simultaneously activating the camera 2 to capture real-time underwater environmental images to assist the operator in locating the sea cucumber, the first motor 12 is activated via an external control device to drive the first rotating shaft 13 to rotate, causing the rotating plate 11 to rotate on the underwater robot 1. This eventually rotates the suction tube 15 (and the suction nozzle 7) directly above the sea cucumber. Then, the second motor 81 is activated to drive the worm gear 82 to rotate. The worm gear 82 meshes with the worm wheel 83 on the rotating plate 11. Because the suction tube 15 is threadedly connected to the worm wheel 83, the rotation of the worm wheel 83 causes the suction tube 15 to slide up and down along the rotating plate 11. Simultaneously, the guide rod 84, which is fixedly connected to the suction nozzle 7, slides synchronously along the rotating plate 11 to ensure smooth lifting and lowering of the suction tube 15 until the suction nozzle 7 is close to the sea cucumber. Afterwards, the suction device 5 is activated, creating a negative pressure at the suction nozzle 7 through the main pipe 6, hose 10, and suction tube 15. This negative pressure draws in the sea cucumber along with seawater, which is then transported through the hose 10 and main pipe 6. The sea cucumber is fed into storage tank 4. During the suction process, some impurities may enter storage tank 4 and not be discharged from the through hole of storage tank 4. At this time, the first motor 12 can be controlled to drive the rotating plate 11 to rotate back and forth, so that the first rotating shaft 13 drives the driving gear 943 to rotate, so that the driven gear 941 rotates synchronously and meshes to drive the rack 93 to slide along the fixed plate 16. The rack 93 is fixedly connected to the cleaning rod 92 in storage tank 4, which drives the cleaning rod 92 to move back and forth along the length of storage tank 4. The slider 17 on the cleaning rod 92 slides along the groove 18 on the inner wall of storage tank 4, so that the sea cucumbers and seawater accumulated in storage tank 4 are evenly spread out, so that the impurities between the sea cucumbers in storage tank 4 are stirred and discharged along the water flow through the through hole of storage tank 4. After the collection is completed, the sea cucumbers can be taken out by opening the cover of storage tank 4. The overall structure and operation steps are simple, the degree of automation is high, the position of the suction nozzle 7 can be flexibly adjusted, and the inside of storage tank 4 can be cleaned at the same time, which improves the versatility of the device.

[0030] This invention achieves flexible positioning of the suction nozzle in three-dimensional space by incorporating a horizontally rotatable rotating plate and a lifting assembly that drives the suction tube to rise and fall. This significantly expands the harvesting range and improves the accuracy and efficiency of sea cucumber capture. The device combines suction equipment with an underwater robot, enabling fully automated operation and effectively reducing the risks and labor intensity of manual harvesting. Simultaneously, the cleaning component inside the storage tank automatically agitates sea cucumbers and impurities during operation, facilitating impurity removal and improving the equipment's continuous operation capability and overall harvest quality. It boasts the advantages of a reasonable structure, simple operation, and strong applicability.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
