The charging port 36 is connected to the battery 32 through a wire, and the battery 32 is charged through the charging port 36. Input on the operation panel 34 The corresponding instructions are transmitted to the control processor, and the control processor sends signals to the corresponding electrical components after processing, so that the corresponding electrical components move. The information fed back by the electrical components is displayed on the display panel 76. The storage cylinder 49 is inserted into the annular groove block 48, and the motor 68 is started, thereby driving the driving gear shaft 69 to rotate, thereby driving the driving gear 67.

After the cover plate 11 is covered on the storage box 5, the sealing motor is started. The sealing screw 56 is driven to rotate, and the sealing screw 56 is threadedly connected to the sealing nut block 55, thereby driving the sealing plate 77 to move, so that the sealing plate 77 seals the connection between the sealing groove 52 and the storage chamber 46, and the pressing motor 13 is started to rotate, thereby driving the drive shaft 71 to rotate, thereby driving the drive gear 72 to rotate, and the drive gear 72 is engaged with the gear 74, thereby driving the pressing shaft 14 to rotate, thereby driving the pressing rotating plate 16 to rotate, thereby driving the fixed disk 15 to rotate, thereby driving the water pipe 30 to rotate, thereby driving the rubber pressing plug 31 to move and insert into the channel 53, so that the channel 53 is sealed and pressed.Seawater is added to the storage cylinder 49 through the water delivery pipe 30, and the seawater enters the storage cylinder 49 through the water delivery one-way valve 54. When it is necessary to take out the sample in the storage cylinder 49 separately, the corresponding channel 53 is opened, and the oxygen supply pump 18 is started, so that the oxygen in the oxygen tank 6 passes through the oxygen detector 37 and the connecting pipe 19 and enters the hollow plate 9. The corresponding control valve 10 is opened. The opening time length of the control valve 10 is different. The oxygen enters the oxygen delivery pipe 29 through the control valve 10, enters the three-way pipe 28 through the oxygen delivery pipe 29, and passes through the one-way valve 61. The gas then enters the through-hole 62, and then the storage chamber 46, and then the storage cylinder 49. The pressurized air pump 59 is activated to inflate the gas, allowing it to enter the hollow guide plate 21 through the delivery connecting pipe 60. The pressure control valve 22 is opened, and the pressure control valve 22 enters the pressure delivery pipe 23. The opening time of the pressure control valve 22 is different. The gas passes through the pressure delivery pipe 23 and enters the three-way pipe 28. It then passes through the one-way valve 61 and enters the through-hole 62, and then enters the storage chamber 46 and the storage cylinder 49, simulating the pressure at the corresponding ocean location.
