the structure of the device for simultaneously collecting marine sediment and a seabed water sample in this embodiment is basically the same as that in embodiment 1, and the difference is only that the structure of the water taking assembly in the water taking tank 3 is different.
Referring to fig. 7 to 10, in embodiment 2 of the present invention, the bottom of the first chute 304 of the water intake assembly is opened and penetrates into the water intake tank 3, and the bottom of the wedge-shaped block 33 passes through the bottom opening and enters into the water intake tank 3, and a float 35 is connected in the water intake tank 3, and the float 35 has a larger volume and a smaller density, for example, may be a hollow rubber body, and the external dimension of the float 35 is larger than the width of the bottom opening, and when the water intake tank 3 is filled with water, the float 35 receives the buoyancy of the water, and moves upwards, so that the entire wedge-shaped block 33 slides upwards along the first chute 304 and rises to the original position, thereby completely blocking the first channel 301. In this structure, as shown in fig. 8 to 10, after sediment sampling is completed, the piston 12 is pulled to the bottom of the sampling tube 2 and is positioned at the same height as the second magnet 32, the second magnet 32 is attracted by the magnetic attraction of the first magnet 14 and moves to the bottom of the second chute 305, so as to be separated from the wedge-shaped block 33, the wedge-shaped block 33 slides down under the action of gravity, so that the third channel 303 is communicated with the first channel 301, and meanwhile, the second channel 302 is communicated, seawater enters the water tank 3 through the communicated channel, when the seawater filled in the water tank 3 reaches the height of the float body 35, the wedge-shaped block 33 receives upward buoyancy due to the buoyancy, and when the buoyancy is greater than the self gravity of the wedge-shaped block 33, the wedge-shaped block 33 starts to float upwards until the first channel 301 is completely blocked, and because the water sample in the water tank 3 does not flow out, the buoyancy is not required to be always present, and the second magnet 32 does not need to be reset to the initial position, so that in this structure, the first magnet 14 can be set as an electric power, compared with the embodiment 1, the power-saving cable is provided, and the magnetic device is more energy-saving, and the magnetic device is set up than the first magnet 14.
