[0002] Sea cucumbers, a type of echinoderm that lives on the seafloor, hold significant economic and nutritional value and are widely used in the food, pharmaceutical, and health supplement industries. Due to their submersible habitat and environmental sensitivity, the development of sea cucumber resources typically relies on manual diving and harvesting. However, sea cucumbers have a wide distribution and complex underwater environment, making natural harvesting inadequate to meet market demand. Therefore, specialized harvesting operations are essential to ensure a stable and sustainable supply.
[0003] Current sea cucumber harvesting technology relies primarily on manual labor by divers, who typically dive to the seabed and grab the sea cucumbers by hand. This requires direct contact with the seabed, exposing divers to potential hazards such as sharp rocks, corals, and toxic marine life, posing a safety threat. To address this issue, a robotic arm-grabbing sea cucumber harvesting device has been proposed. Utility Model Content

[0029] The following will be combined with the drawings in the specification of this utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility model.
[0030] Reference Figure 1-Figure 3The lifting of the ...
[0031] By gripping the grip 9 on one side of the bottom of the support arm 1, the grip 9 drives the connected pull rod 10, the mounting frame 16 and the reel 11 to move as a whole and approach the support arm 1, so that the reel 11 applies a tightening force to the pull rope 12, and then pulls the swing arm 4 to make the clamping claw 5 approach the collection net 23, thereby achieving the purpose of grabbing the sea cucumber and moving it into the collection net 23. After releasing the grip 9, the spring 8 applies a rebound force to the convex plate 7, pushing the top rod 6, the swing arm 4 and the clamping claw 5 to reset and return to the initial state to prepare for the next operation. Therefore, there is no need for the diver to directly contact the sea cucumber or the seabed, avoiding contact with potential dangerous objects that may exist, and enhancing safety.
[0032] Reference Figure 1 and Figure 2 The adjusting mechanism includes a fixing frame 17, the spool 11 is rotatably connected to the inside of the fixing frame 17, the fixing frame 17 is fixedly connected to the bottom of the mounting frame 16, the middle part of the fixing frame 17 is fixedly connected to a threaded rod 18, the threaded rod 18 passes through the spool 11, and a knob 19 is threadedly connected to one side of the threaded rod 18.
[0033] Rotating the knob 19 can drive the threaded rod 18 to move along the thread direction, apply pressure to the reel 11, and then control the rotation state of the reel 11. When the knob 19 is tightened, the threaded rod 18 presses the reel 11, restricting its rotation, thereby fixing the length of the pull rope 12, ensuring that the pull rope 12 will not loosen during the grabbing operation, and ensuring that the clamping jaws 5 can stably and accurately approach and grab the sea cucumber. On the contrary, when the knob 19 is loosened, the rotation restriction of the reel 11 is released, and the pull rope 12 can be freely released or tightened.
[0034] Reference Figure 3A sleeve 13 is fixedly connected to one side of the middle portion of bracket 3, with one side of spring 1 8 located within sleeve 13. A guide wheel 14 is mounted on the top of the outer wall of arm 1, and a guide wheel 2 15 is mounted on the bottom of each arm. The pull rope 12 passes through the top of guide wheel 14 and the bottom of guide wheel 2 15. A through hole is opened in the middle of bracket 3, and the pull rope 12 passes through the through hole.
[0035] The spring 1 8 can be assisted in being fixed by the sleeve 13 to avoid it from falling off, and the expedition team pulls the rope 12 for guidance using the guide wheel 14 and the guide wheel 2 15 .
[0036] Reference Figure 1 and Figure 4 The bottom of the support arm 1, near the collection net 23, is rotatably connected to a pressure rod 20. An insertion rod 22 is fixedly connected to the top of the pressure rod 20. A second spring 21 is provided on the other side of the top of the pressure rod 20. The second spring 21 is connected to the bottom of the support arm 1. The insertion rod 22 passes through the support arm 1 and enters the support arm 2. The bottom surface of the support arm 2 is provided with multiple grooves, and the insertion rod 22 is located in one of the grooves. The bottom surface of the support arm 1 is provided with a slot, and the top of the second spring 21 is located in the slot.
[0037] By pressing the pressure rod 20, the spring 21 will be compressed, so that the insertion rod 22 is moved out of the groove of the support rod 2, so that the support rod 2 can slide in the support arm 1, thereby adjusting the overall length of the device. When the pressure rod 20 is released, the spring 21 will return to its original state, pushing the insertion rod 22 back into the groove at the bottom of the support rod 2, thereby stabilizing the position of the support rod 2. This makes it convenient for divers to adjust the length of the device according to environmental requirements, and also ensures a stable connection between the support arm 1 and the support rod 2, thereby increasing the flexibility and reliability of the device.
[0038] Working principle: When in use, tighten the knob 19 to squeeze the fixing frame 17. At this time, the fixing frame 17 squeezes the reel 11 to prevent it from releasing the pull rope 12. When it is necessary to catch the sea cucumber, first move the movable clamping claw 5 and the collecting net 23 so that they are on both sides of the sea cucumber, and then hold the support arm 1 close to one side of the gripping rod 9. When grabbing, pinch the gripping rod 9 with your fingers to bring it close to the support arm 1. At this time, the gripping rod 9 will pull the pull rod 10 close to the support arm 1, thereby driving the mounting frame 16, the fixing frame 17 and the reel 11 close to the support arm 1, and the reel 11 cannot release the pull rope 12, so the pull rope 12 can be pulled, thereby driving the swing arm 4 close to the collecting net 23. At this time, the sea cucumber can be grabbed and moved into the collecting net 23, and the spring 18 is compressed at this time. After the grabbing is completed, release the gripping rod 9. At this time, spring 1 8 will apply pressure to convex plate 7, thereby extending convex plate 7 and push rod 6, and then pulling grip rod 9 to reset, and then the next grab can be performed. When in use, after loosening knob 19, the fixing frame 17 will not press the reel 11, and the pull rope 12 can be released at this time, and then press one side of the pressure rod 20 to compress spring 21. At this time, the insertion rod 22 will be moved out of the groove on the bottom surface of the support rod 2, and the support rod 2 can be pulled to slide in the support arm 1. At this time, the length of the combination between the support rod 2 and the support arm 1 can be extended. After loosening the pressure rod 20, spring 2 21 is reset and then squeezes one side of the pressure rod 20 to re-penetrate the support arm 1 and insert it into the groove on the bottom surface of the support rod 2, then rotate the reel 11 to tighten the pull rope 12, and finally tighten the knob 19.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
