[0028] A disc 15 is provided at the upper end of the column 2, and the opening and closing mechanism is mounted on the disc 15;

[0029] A sealing cover 16 is provided at the upper end of the disc 15 , and the opening and closing mechanism is arranged inside the sealing cover 16 .

[0030] The opening and closing mechanism comprises a motor 5, a rotating disc 6 is provided at the output end of the motor 5, a rotating arm 7 is provided in the radial direction of the rotating disc 6, a rotating block 8 is provided at the lower end of the rotating arm 7, and a rotating wheel 9 is rotatably installed on the outer side of the rotating block 8;

[0031] A lifting column 10 is provided at the upper end of the sealing cover 4, a limit block 11 is provided at the upper end of the lifting column 10, and the limit block 11 is located above the disc 15, a connecting block 12 is provided at the upper end of the limit block 11, a lifting block 13 is provided at the lower end of the connecting block 12, and inclined surfaces 14 are provided on both sides of the lower end of the lifting block 13.

[0032] A spring 21 is sleeved on the outer diameter of the lifting column 10 , and the spring 21 is located between the disc 15 and the sealing cover 4 .

[0033] A sealing gasket 17 is provided at the lower end of the sealing cover 4 .

[0034] A countersunk hole is provided at the upper end of the column 2, and the motor 5 is installed in the countersunk hole.

[0035] The sealing cover 16 is used to protect the opening and closing mechanism to prevent seawater from entering, and the sealing gasket 17 can increase the sealing performance of the sampling tube 3. Before sampling seawater, the rotating wheel 9 is located between two adjacent lifting blocks 13. When in use, the lifting blocks 13 are lifted by the rotating wheel 9 to open the sealing cover 4, so that seawater enters the sampling tube 3 for sampling;

[0036] The motor 5 drives the turntable 6 to rotate 45 degrees, and the turntable 6 drives the wheel 9 to rotate 45 degrees through the rotating arm 7 and the rotating block 8. During the rotation of the wheel 9, the wheel 9 will come into contact with the lifting block 13. First, the wheel 9 contacts the inclined surfaces 14 on both sides of the lifting block 13. Since the wheel 9 is rotatably installed on the rotating block 8, the friction between the wheel 9 and the inclined surface 14 causes the wheel 9 to rotate, reducing the friction between the wheel 9 and the lifting block 13, increasing the stability and durability of the mechanism. On the other hand, the wheel 9 will lift the lifting block 13 through the inclined surface 14, and the lifting block 13 drives the sealing cover 4 to rise through the connecting block 12 and the lifting column 10. The spring 21 is compressed, and the sealing cover 4 is opened. At this time, seawater can enter the sampling tube 3 The rotary wheel 9 is driven by the motor 5 to rotate 45 degrees, and the rotary wheel 9 is located directly below the lifting block 13. At this time, the sealing cover 4 is farthest from the opening of the sampling tube 3, and the sampling speed is the fastest. After the seawater sampling is completed, the motor 5 continues to rotate 45 degrees to separate the rotary wheel 9 from the lifting block 13. The sealing cover 4 will quickly drop to seal the sampling tube 3 through the elastic force of the compressed spring 21, completing the first stage of seawater sampling. The second stage of seawater sampling can be carried out by changing the sampling depth or position. The second stage of seawater sampling is the same as the first stage. The second sampling tube 3 is sampled for seawater through two 45-degree rotations, and four seawater samplings can be carried out in sequence.

[0037] The four groups of sampling tubes 3 are respectively fixed by four groups of clamping devices;

[0038] The clamping device is composed of two buckles 20, the buckle 20 is C-shaped, and the buckle 20 is fixed on the column 2 through a fixing block;

[0039] The upper end of the bottom plate 1 is provided with four groups of sinks 18 corresponding to the buckles 20, and the lower end of the sampling tube 3 abuts against the bottom of the sink 18;

[0040] The bottom plate 1 is provided with a plurality of through holes 19;

[0041] A pull ring 22 is provided at the middle of the upper end of the sealing cover 16 .

[0042] Among them, the pull ring 22 is used to connect the pull rope, which is convenient for the retraction and release of the device when sampling. The several through holes 19 on the bottom plate 1 can make seawater gush out from the through holes 19, increasing the sinking speed of the device. The sampling tube 3 can be removed from the clamping device, which is convenient for the use of the sampled seawater. The sinking pit 18 is used to limit the bottom of the sampling tube 3. When the sampling tube 3 needs to be removed, the sealing cover 4 is opened by rotating the motor 5 45 degrees. The sampling tube 3 can be removed by pulling it towards the notch of the buckle 20, and then the four sampling tubes 3 can be removed in turn.

[0043] The working principle and use process of this utility model:

[0044] First, tie the pull rope to the pull ring 22, and then put the device into the seawater. At this time, the rotating wheel 9 is located between two adjacent lifting blocks 13, and the sampling tube 3 is in a sealed state by the sealing cover 4. After the sampling tube 3 reaches the sampling position, start the motor 5, and the motor 5 drives the turntable 6 to rotate 45 degrees. The turntable 6 drives the rotating wheel 9 to rotate 45 degrees through the rotating arm 7 and the rotating block 8. During the rotation of the rotating wheel 9, the rotating wheel 9 will come into contact with the lifting block 13. First, the rotating wheel 9 contacts the inclined surfaces on both sides of the lifting block 13. The rotating wheel 9 is rotatably mounted on the rotating block 8, so the rotating wheel 9 and the inclined surface 14 rub against each other to make the rotating wheel 9 rotate, thereby reducing the friction between the rotating wheel 9 and the lifting block 13, and increasing the stability and durability of the mechanism. On the other hand, the rotating wheel 9 will lift the lifting block 13 through the inclined surface 14, and the lifting block 13 drives the sealing cover 4 to rise through the connecting block 12 and the lifting column 10, and the spring 21 is compressed, and the sealing cover 4 is opened. At this time, seawater can enter the sampling tube 3 to take seawater samples. When the rotating wheel 9 is driven by the motor 5 When the driving rotation is 45 degrees, the wheel 9 is located directly below the lifting block 13. At this time, the sealing cover 4 is the farthest from the opening of the sampling tube 3, and the sampling speed is the fastest. When the seawater sampling is completed, the motor 5 continues to rotate 45 degrees to make the wheel 9 disengage from the lifting block 13. The sealing cover 4 will quickly drop to seal the sampling tube 3 through the elastic force of the compressed spring 21, completing the seawater sampling of one stage. The seawater sampling of the second stage can be carried out by changing the sampling depth or position. The seawater sampling of the second stage is the same as the sampling of the first stage. The second sampling tube 3 is sampled with seawater through two 45-degree rotations. Four seawater samplings can be carried out in sequence. After the sampling is completed, the sampling barrel 3 can be pulled out of the water by the pull rope; in addition, the sampling tube 3 can be removed from the clamping device, which is convenient for using the sampled seawater. When the sampling tube 3 needs to be removed, the sealing cover 4 is opened by rotating the motor 5 45 degrees, and the sampling tube 3 can be pulled toward the notch of the buckle 20 by hand to remove it, and then the four sampling tubes 3 can be removed in sequence.
