[0002] Polymetallic nodules are found on the surface of seafloor sediments, often at depths exceeding 4,500 meters.

The probe is then tensioned and lifted. When the device is unhooked, the cable connected to the natural potential probe is also removed. The probe then penetrates the sediment under its own weight, with the buckled dual wheels limiting its position and slowing its downward momentum. However, the device suffers from the following drawbacks:

[0015] Preferably, a monitoring method of an environmental monitoring device used in deep-sea polymetallic nodule mining is characterized in that the monitoring method is as follows:

[0016] S1. Detection: When the electromagnet is energized, it generates an attractive force on the magnetic block, thereby pulling the longitudinal connecting plate toward the storage cylinder. The second piston moves, and under the action of air pressure, the probe rod moves downward, so that the probe rod is inserted into the sediment for natural potential detection;

[0018] S3. Cleaning: When the longitudinal connecting plate moves, it drives the rack to move, and drives the rotating ring to rotate, so that the outer wall of the bristles is cleaned. At the same time, when the probe moves downward, seawater enters the water tank. When the probe moves back to its original position, the water tank is opened for flushing.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1) During operation, the rack moves back and forth horizontally along with the longitudinal connecting plate, and the rack engages with the tooth grooves on the outer wall of the rotating ring, thereby driving the rotating ring to rotate. During the longitudinal movement of the probe rod, the bristles on the inner wall of the rotating ring brush the outer wall of the probe rod, making it easy to remove the sediment adhered to the probe rod before detection and the sediment removed after detection, thereby improving the accuracy of natural potential detection;

[0021] 2) During operation, when the probe rod moves downward, the rack pushes the third piston toward the side away from the storage tube, allowing seawater to enter the water tank. When the probe rod returns to its original position, the third piston is released to discharge the seawater, making it easier to impact the probe rod and improve the accuracy of subsequent natural potential detection. When seawater enters, the third piston moves to a position where it engages with the block. When the probe rod returns to its original position, the first piston pushes the push rod to move, causing the second gear plate to move, and the block is pulled upward by the connecting rod, causing the third piston to release, thereby avoiding affecting the return movement of the probe rod.

[0022] 3) During operation, a push rod is fixedly connected to the rack, a push plate is installed on the end of the push rod, and an insertion rod is installed on the push plate. The insertion rod is inserted into the slot on the end plate. When the probe moves upward, the push rod pushes the end plate to move, driving the third piston to move to collect seawater. When the longitudinal connecting plate moves back, the insertion rod is pulled out of the slot, so that the third piston will not affect the return movement of the probe when it is not released, making it easy to retract;

[0023] 4) During operation, when the probe moves downward, the longitudinal connecting plate moves toward the side of the storage tube, driving the rotating ring to rotate. The fan blades rotate with the top ring, playing a diversion role, driving seawater into the storage tube, facilitating the entry of seawater into the water tank. At the same time, when the probe moves downward, a certain resistance is generated on the bottom wall of the first piston, ensuring that the probe moves downward smoothly and improving detection stability.

When the probe rod 3 moves downward, the rack 501 pushes the third piston 603 toward Move away from the storage tube 1, and let seawater into the water tank 601. When the probe rod 3 returns to its original position, the third piston 603 releases to discharge the seawater, facilitating the impact on the probe rod 3 and improving the accuracy of subsequent natural potential detection. When seawater enters, the third piston 603 moves to a position where it engages with the block 613. When the probe rod 3 returns to its original position, the first piston 2 pushes the push rod 619 to move, causing the second gear plate 624 to move. The block 613 is pulled upward by the connecting rod 616, causing the third piston 603 to release, avoiding affecting the return movement of the probe rod 3.

[0040] Working principle: The device is used in the ocean. When the natural potential of the sediment needs to be detected, the electromagnet 410 is energized, causing the electromagnet 410 to generate an attraction force on the magnetic block 409, thereby pulling the second crossbar 407 toward the storage tube 1, and then driving the longitudinal connecting plate 404 to move toward the storage tube 1, causing the second piston 402 to move. Under the action of air pressure, the probe rod 3 is pushed downward to penetrate into the sediment to detect the natural potential. When the electromagnet 410 is de-energized, the longitudinal connecting plate 404 moves back under the elastic force of the first spring 408, and under the action of air pressure, the probe rod 3 is pulled back upward to be retracted;

[0041] During the reciprocating movement of the longitudinal connecting plate 404, the rack 501 is mounted on the longitudinal connecting plate 404, and the rack 501 engages with the tooth groove 505 on the outer wall of the rotating ring 504, thereby driving the rotating ring 504 to rotate. During the rotation, the bristles 506 clean the surface of the probe rod 3 to prevent other deposits from adhering to the outside of the probe rod 3 and affecting the detection accuracy.

[0042] When the longitudinal connecting plate 404 moves toward the storage tube 1, the rack 501 moves through the push plate 608 to push the end plate 606 to move, so that the third piston 603 moves toward the side away from the storage tube 1, so that seawater enters the water tank 601. When the third piston 603 moves to the corresponding position of the card slot 611 and the card block 613, the third piston 603 generates pressure on the extrusion slope 614, pushing the card block 613 to move upward. When the card slot 611 moves to below the card block 613, the card block 613 moves downward and is stuck in the card slot 611, clamping and fixing the third piston 603. When the longitudinal connecting plate 404 moves back, the push rod The back movement of 607 will not drive the end plate 606 to move back. When the first piston 2 moves to the height corresponding to the side box 617, the first piston 2 pushes the push rod 619 to move toward the side away from the storage tube 1, and then drives the second tooth plate 624 to move toward the side of the storage tube 1 through the first tooth plate 623 and the gear body 625, and then drives the clamping block 613 to move upward and disengage from the clamping groove 611 through the connecting rod 616. At this time, the third piston 603 moves back under the elastic force of the second spring 605, pushing seawater out of the water tank 601 and impacting the outer wall of the probe rod 3, further cleaning the adhered sediment and ensuring the accuracy of subsequent detection;

[0043] When the probe rod 3 moves downward, the longitudinal connecting plate 404 moves toward the side of the storage tube 1, driving the rotating ring 504 to rotate. At this time, the top ring 507 rotates, driving seawater into the interior of the storage tube 1 through the fan blades 508, making it convenient for seawater to enter the water tank 601. At the same time, when the probe rod 3 moves downward, a certain resistance is generated on the bottom wall of the first piston 2, ensuring that the probe rod 3 moves downward smoothly, thereby improving the detection stability.
