[0028] Working principle: During monitoring, the electromagnetic lock 109 is opened, the UAV body 201 is started, and the ring motor 304 is started at the same time. After the UAV body 201 is started, it flies to a high point in the air for detection. After the ring motor 304 is started, it drives the inner through hole 307 to rotate. The rotation of the inner through hole 307 realizes the winding and unwinding of the signal and power tethering line 303, thereby ensuring that the UAV body 201 continuously receives power and signal wired connection, forming a tethering with the unmanned surface vessel body 101. When recovering the drone body 201, the drone body 201 is moved above the parking slot 108. The drone body 201 is located through the infrared positioning receiver 112 and the infrared positioning transmitter 203. Then the drone body 201 is accurately lowered into the parking slot 108 until the lock head 205 engages with the electromagnetic lock 109 and finally locks in place. After recovering the drone body 201, the drying fan 105 is started and the heating wire 107 is energized. After the drying fan 105 starts, it blows air into the parking slot 108. The cold air outside is heated into hot air after passing through the heating wire 107, thereby drying the bottom of the drone body 201. Then the moisture is discharged from the exhaust door 110 with the hot air. During sampling, the drone body 201 is hovered at a designated position on the water surface, immersing the bottom of the sampling cylinder 402 in the water. When the water level triggers the water level detection sensor 408, the electromagnetic coil 404 is activated. The electromagnetic coil 404 generates electromagnetic force that pushes the magnet block 405, causing the suction piston 403 to press down and the suction spring 411 to contract, thereby expelling the air from inside the sampling cylinder 402. Then, the electromagnetic coil 404 is turned off, and the suction spring 411 returns to its original position. When the suction spring 411 returns to its original position, it pushes the suction piston 403 outward, thereby generating negative pressure to draw water out of the sampling cylinder 402, thus completing the sampling.
