[0002] In the field of ships, underwater monitoring and sampling are very important tasks. Traditional underwater equipment has some obvious limitations. First, it is inconvenient to operate. Traditional equipment often requires operators to operate it on site in person, which not only increases the workload of operators, but may also be affected by the harsh underwater environment, bringing safety risks to operators. Secondly, the flexibility is poor. These devices are not maneuverable enough and are difficult to adapt to the complex and changeable underwater environment, which limits their application in different scenarios. Furthermore, accurate sampling is impossible. Traditional equipment may be interfered by various factors during the sampling process, resulting in inaccurate sampling results, which cannot meet the needs of scientific research and practical applications.

[0031] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0032] When underwater monitoring is required, the bracket 71 is fixed on the deck of the ship, the main body 1 is remotely connected to the external operating panel via WIFI, and the main body 1 is started. The main body 1 is used to power the electromagnet 24 and the de-energized electromagnet 25. The circuit of the electromagnet 24 is connected to make it magnetic, and the circuit of the de-energized electromagnet 25 is connected to make it demagnetized. Then, the electromagnet 24 can be used to magnetically absorb the drag rod 26 to move to the left until the drag rod 26 moves out of the inner cavity of the drag slot 22, and the object to be dragged is hung in the inner cavity of the drag slot 22. The main body 1 turns off the power supply of the electromagnet 24 and the de-energized electromagnet 25, and then moves in the opposite direction to the above, causing the drag rod 26 to move to the right, and fix the object in the inner cavity of the drag slot 22. , put the main body 1 into the water under the ice surface, start the third motor 715, the output end of the third motor 715 drives the first gear 717 to rotate through the second connecting rod 716, and then the first gear 717 is used to drive the second gear 719 to drive the wire reel 718 to rotate, and the wire reel 718 rotates to release the wire 720, and the main body 1 is started by the reed switch magnetic switch 8. The main body 1 is started, which prompts the LED lamp bead 9 to start, and the LED lamp bead 9 can be used to remind the position of the main body 1, and the first motor 19 is started. The output end of the first motor 19 drives the spiral blade 21 to rotate through the rotating rod 20, and the rotation of the spiral blade 21 can prompt the main body 1 to move, and the camera 29, the LED strong light 30 and the sonar are started. 31. The images monitored by the camera 29 are constantly displayed on the operating panel display. The sonar 31 detects the depth of the main body 1 to the bottom of the water, whether there are obstacles ahead during driving, and floating objects in the water (only larger than 10 cm will be reflected) will be fed back to the operating panel display. The LED strong light 30 is used to provide lighting. The two first motors 19 drive the spiral blades 21 on both sides to rotate, which can prompt the main body 1 to move forward. The spiral blade 21 on the left stops rotating, and the number of revolutions of the spiral blade 21 on the right remains unchanged to achieve a turn, or the spiral blade 21 on the right stops rotating, and the number of revolutions of the spiral blade 21 on the left remains unchanged to achieve a turn. When the main body 1 moves to a suitable position, the spiral blade 21 stops rotating and waits in place. The main body 1 is used as an electromagnet 24 and a power-off type electromagnetic The electromagnet 25 is powered, and then the same action as above is performed, so that the dragging rod 26 moves to the left, and then it can contact the shielding of the dragged object, and the dragged object falls into the water. Then the power supply of the electromagnet 24 and the power-off type electromagnet 25 is turned off, so that the dragging rod 26 is restored to the initial position, and the electric telescopic rod 13 is started. The bottom hatch 12 is pulled to the rear side by the electric telescopic rod 13 until the inner cavity of the sampling cabin 2 leaks out, and the seawater at the current position can be collected, so that accurate sampling operations can be performed. When it is necessary to retract the main body 1, the second motor 78 and the third motor 715 are started while the main body 1 is moved. The third motor 715 moves in the opposite direction to the above to cause the wire 720 to be wound around the outer wall of the take-up drum 718.At the same time, the output end of the second motor 78 can drive the chain 77 to drive the slide post 79 to make circumferential motion through the first connecting rod 75 and the sprocket 76. The slide post 79 can use the moving plate 711 and the moving groove 712 to drive the roller 713 to move back and forth, thereby filtering the wires and preventing the wires 720 from being messed up, thereby realizing wire collection. If maintenance is required, the nut 28 can be rotated until the nut 28 is separated from the outer wall of the second guide rod 6, and the water tank 15 can be slid backward to separate the water tank 15 from the main body 1, thereby facilitating maintenance.
