[0037] A plurality of first tripods 100 are arranged on the outer wall of the installation housing 1, and a floating block 101 is connected to the bottom of each first tripod 100 to ensure that the device floats on the sea surface. A mounting shell 104 is arranged at the bottom of the installation housing 1, and a plurality of telescopic cylinders 800 are arranged in the installation shell 104 to form a holding assembly 8. The telescopic rods of the telescopic cylinders 800 are movably arranged in a sliding sleeve 105 on the inner bottom surface of the installation housing 1, and the top of the telescopic rods is connected to the top plate 803 through a connecting plate 801 and a bolt 802. A bearing seat 80 is arranged at the center of the top of the top plate 803. 5. The transmission shaft 908 on the transmission end of the internal motor 900 is movably arranged in the bearing seat 805. The bottom of the turntable 901 on the top of the transmission shaft 908 has several legs 902. The casters 903 at the bottom of the legs 902 are fitted on the inner bottom surface of the movable groove 804 on the top of the top plate 803. The water inlet and outlet of the water pump 904 on the top of the turntable 901 are respectively connected to the water pipe 1 906 and the water pipe 2 907. The ports of the water pipe 1 906 and the water pipe 2 907 away from the water pump 904 are both provided with sealing rings 2 905;

[0038] Several water pumping pipes 7 are arranged downward inside the installation shell 1. A sealing ring 702 is arranged on the top of one end of the water pumping pipe 7 located inside the installation shell 1, and a bowl-shaped shell 701 is arranged on the outer wall. A filter screen 700 is arranged at the bottom, which are 1m, 3m and 5m respectively. Several transmitting sensors 10 are arranged on the inner wall of the installation shell 1, which are respectively located directly behind the several water pumping pipes 7. A receiving sensor 11 is arranged on the front of the water delivery pipe 906. The receiving sensor 11 is connected to the motor 900 control, and the motor 900 and the water pump 904 are electrically connected to the battery in the battery protection compartment 6;

[0039] Several pairs of limit blocks 106 are also arranged on the inner bottom surface of the installation housing 1, and each pair of limit blocks 106 is respectively located in front of several water extraction pipes 7, and limit plugs 1200 symmetrically arranged on both sides of the sampling storage box 12 are inserted between each pair of limit blocks 106.

Under the action of several floating blocks 101, the device can float on the sea surface. Then, the ship continues to travel and drags the device to the sea area that needs to be inspected.

[0041] When arriving at the designated sea area, sampling operation can be carried out. When collecting seawater at a depth of 1 meter, the transmitting actuator located behind the 1-meter water pumping pipe 7 will send a signal, and then the motor 900 will start, driving the turntable 901 to rotate through the transmission shaft 908, and then driving the water pump 904 to rotate together. When the receiving actuator on the water pipe 1 906 receives the signal of the transmitting actuator behind the 1-meter water pumping pipe 7, the motor 900 stops rotating. Subsequently, several telescopic cylinders 800 will retract the telescopic rods at the same time, and the ports of the water pipe 1 906 and the water pipe 2 907 will be firmly attached to the water inlet ports of the water pumping pipe 7 and the sampling storage box 12. After that, the water pump 904 will start, and the seawater 1 meter below the sea surface will be extracted through the 1-meter water pumping pipe 7 and discharged into the sampling storage box 12 to complete the collection. After the collection is completed, the above steps are repeated to extract seawater 3 meters and 5 meters below the sea surface.

[0042] After all the extraction is completed, the operator can pull the device back by pulling the rope, then open the top cover 2, remove several sampling storage boxes 12 that have been filled with seawater samples, reinstall several empty sampling storage boxes 12, and then replace the top cover 2. Then, the device can be carried to the next sea area for extraction and sampling.
