[0023] In this embodiment, the wire feeding mechanism also includes a wire feeding roller 2, a steel cable 3, and a guide metal block 4.

The steel cable 3 passes through the guide hole, and the other end of the steel cable 3 is fixedly connected to the connecting buckle 8.

[0024] In this embodiment, a motor slot is provided inside the connecting base 1, and the motor slot is connected to the shaft feeding slot. A shaft feeding ratchet 5 is fixedly installed on one side of the feeding roller 2, and a shaft feeding servo motor 7 is fixedly installed on the inner wall of one side of the motor slot. A limiting ratchet 6 is fixedly sleeved on the output shaft of the shaft feeding servo motor 7, and the limiting ratchet 6 is adapted to the shaft feeding ratchet 5.

[0025] In this embodiment, an anchoring metal block 23 is fixedly installed at the bottom of the anchoring body 10, so that the anchoring body 10 can be driven into the silt after sinking to the bottom for fixation.

[0026] In this embodiment, the replacement mechanism includes a dual-axis motor 22, two worm gears 20, and two worm wheels 19. The clamp base 14 has a replacement chamber inside. A motor housing 21 is fixedly installed on one inner wall of the replacement chamber. The dual-axis motor 22 is fixedly installed on the inner side of the motor housing 21. Worms 20 are rotatably installed on both sides of the motor housing 21. The two output shafts of the dual-axis motor 22 are fixedly connected to the corresponding worm gears 20. Two worm wheels 19 are rotatably installed on the bottom inner wall of the replacement chamber. The two worm wheels 19 mesh with the corresponding worm gears 20.

[0027] In this embodiment, clip slots are provided on both sides of the clip base 14. Both clip slots are connected to the same replacement chamber. Clip shafts 18 are rotatably installed on the bottom inner walls of both clip slots. Two worm gears 19 are respectively fixedly sleeved on the corresponding clip shafts 18. The corresponding clip shafts 18 can be rotated by the two worm gears 19.

[0028] In this embodiment, clips 16 are fixedly sleeved on both clip shafts 18, and counterweight metal blocks 15 are fixedly installed on one side of both clip bases 14. Each of the two clips 16 clamps a corresponding automatic sampling canister 17 on one side, which facilitates the disassembly of the automatic sampling canister 17. The automatic sampling canister 17 adopts the automatic sampling canister proposed in the published patent number CN208621365U. The automatic sampling canister is composed of components such as an electromagnetic coil, a movable spring, and a sealing cover. Since the working principle and connection method of this structure have been described in detail in the published patent documents, it will not be described in detail in this embodiment.

[0029] In this embodiment, an underwater camera 13 is fixedly installed on one side of the anchoring body 10 to facilitate staff to observe the underwater situation.

[0030] Working principle: During use, after the unmanned survey vessel is remotely controlled to move to the designated position, the anchoring mechanism is activated remotely. At this time, the power supply to the two electromagnets 12 is cut off, and the two electromagnets 12 lose their magnetic force. The two magnetic blocks 11 fall with gravity, thus the anchoring body 10 sinks. Since the bottom of the anchoring body 10 is equipped with an anchoring metal block 23, and each of the two clamping bases 14 is equipped with a counterweight metal block 15 on one side, the water flow has little impact on the anchoring body 10 during its sinking, preventing it from deviating from the preset area. When the anchoring body 10 sinks to the bottom of the water, the anchoring metal block 23 comes into contact with the bottom silt. The shape of the anchoring metal block 23 allows it to embed itself into the silt for better fixation. After the staff observes that the anchoring body 10 has sunk to the bottom through the underwater camera 13, multiple automatic retrieval devices are activated remotely. After the automatic sampling tank 17 samples the water, the staff remotely starts the release servo motor 7. The release servo motor 7 drives the limit ratchet 6 to rotate. At this time, the wire feeding roller 2 rotates clockwise. The clockwise rotation of the release ratchet 5 causes motion interference with the limit ratchet 6. Therefore, the start of the release servo motor 7 drives the release ratchet 5 to rotate through the limit ratchet 6, which in turn drives the wire feeding roller 2 to rotate, retracting the steel cable 3 and pulling the anchor body 10 to rise and reset. When the anchor body 10 moves to the designated position, the staff activates the two electromagnets 12. When powered on, the two electromagnets 12 generate magnetic force to attract the corresponding magnetic blocks 11, thus positioning the anchoring body 10. Subsequently, the unmanned survey vessel is controlled to return to port. When the staff disassembles the automatic sampling tank 17, they only need to start the dual-axis motor 22 through the control panel. The start of the dual-axis motor 22 drives the two worm gears 20 to rotate, which in turn drives the corresponding worm wheels 19 to rotate. The rotation of the two worm wheels 19 drives the corresponding clamp shafts 18 to rotate, and the rotation of the two clamp shafts 18 drives the corresponding clamps 16 to flip. At this time, the staff can easily remove the automatic sampling tank 17.

[0031] The technological advancements of this invention compared to existing technologies are as follows: the sampler body can be lowered to contact the silt at the bottom of the water body, enabling sampling of deeper water bodies and expanding the sampling range. Furthermore, the automatic sampling tank 17 can be easily and quickly disassembled, facilitating the removal of the tank after sampling and allowing for the replacement of different models and with different uses of the automatic sampling tank 17, thus increasing the practicality of the equipment and the diversity of sampling methods.
