Description

Technical Field

[0001] The utility model relates to the technical field of underwater fishing, in particular to a sea cucumber fishing robot. Background Art

[0002] At present, sea cucumbers are generally caught manually, and machine fishing is rarely used. Manual fishing is cumbersome and labor-intensive, requiring divers to wear diving suits and oxygen masks to dive to the bottom of the sea, find sea cucumbers and pick them up one by one and put them into net bags. This fishing method is not only inefficient, but also factors such as low sea water temperature, high underwater pressure and harsh underwater environment will increase the difficulty of manual fishing. Most of the existing machine fishing equipment is too bulky and costly, the accuracy of searching for sea cucumbers is not high, and the obstacle-crossing ability is unsatisfactory, resulting in low fishing efficiency.

The four wheel motors are installed on both sides of the hollow part of the frame through the wheel motor mounting plate, two on each side, and a control module is installed between the two motors on each side; the anti-sinking wheel is connected to the wheel motor through a wheel connector. A detachable storage net box is installed at the lower end of the opening of the floating block to store the sucked sea cucumbers. The top front end and the top rear end of the frame are installed with a lighting camera module.

[0006] Further, the adsorption mechanism includes a suction pump, a three-way joint, a hose, a hose mounting bracket, and a sealing plate. The suction pump is installed in the rear port of the three-way joint. The lower port of the three-way joint is installed on the flange mounting plate of the switch door through a flange member. The sealing plate is installed under the flange mounting plate through a hinge. One end of the hose is installed in the front port of the three-way joint, and the other end is installed on the end piece of the three-degree-of-freedom robotic arm mechanism. The middle part of the hose is fixed to the large and small arms of the three-degree-of-freedom robotic arm mechanism by a plurality of the hose mounting brackets, so that the robotic arm can accurately send the inlet end of the hose to the designated position.

[0007] Further, the control module receives power and instructions through cables, and controls the wheel motors, the suction pump, the three-degree-of-freedom robotic arm mechanism, and the camera module with external instructions.

[0008] Further, the four-wheel drive vehicle carrier mechanism moves forward and backward by the forward and reverse rotations of the left and right side wheel motors, and steers by the left and right wheel differential.

[0009] The present utility model realizes the adsorption and fishing of sea cucumbers through a mechanical cooperation form, greatly reducing the labor cost. This device uses four wheel motors to drive four large-diameter anti-sinking wheels respectively, so that the overall vehicle body has extremely high flexibility and excellent obstacle-crossing ability, and can carry out fishing operations in deep sea and complex sea water environments; the added floating blocks enable the negative buoyancy of the entire device in water to reach within ten kilograms; the three-degree-of-freedom robotic arm can accurately send the adsorption hose to the vicinity of the adsorbed object; the rear port of the three-way joint is the suction pump installation port, and there is a metal mesh inside to prevent sea cucumbers from entering the rear port; the front port is the hose installation port, and sea cucumbers enter through this port; the lower port is the channel for sea cucumbers to enter the storage net box; there is a certain space in the middle of the three-way joint for temporarily storing the sucked sea cucumbers; the sealing plate can open or close the lower port of the three-way joint under the action of the adsorption force.

[0023] Specifically, when the entire device is powered on, the robot is controlled to dive into the water, and the underwater lighting and camera device sends the real-time situation at the bottom of the water to the onshore computer through a cable. When sea cucumbers are found, the staff controls the three-degree-of-freedom robotic arm mechanism to send the inlet end of the hose near the sea cucumbers.

The sucked-up sea cucumbers also fall from the temporary storage area into the storage net box. Repeat the above steps. After the storage net box is full, the robot is pulled to the water surface through the cable, the switch door is opened, the storage net box is taken out, and the sea cucumbers are poured out or a new storage net box is replaced.
