The rotating disk 2 is provided with a plurality of mounting grooves 201, and the fan-shaped bottle 3 is installed in the mounting groove 201 of the rotating disk 2, and the fan-shaped bottle 3 is used to hold the sample liquid. The fan-shaped bottle 3 is made of transparent or translucent plastic, glass and other materials, has good chemical stability and corrosion resistance, and is suitable for long-term storage of sample liquid. A first liquid outlet 301 is provided at the bottom of the fan-shaped bottle 3, and a first protrusion 601 is provided at one end of the sealing plug 6. The protrusion is located in the fan-shaped bottle 3 and is tightly abutted with the first liquid outlet 301 to form a seal to prevent the sample liquid from leaking in a non-released state. The other end of the sealing plug 6 extends out of the fan-shaped bottle 3, which facilitates external operation of the sealing plug 6 when discharging the sample liquid in the fan-shaped bottle 3 when needed.

[0046] Furthermore, it also includes a first mounting frame 5, which is arranged on the frame shell 1; a first telescopic member 7 is arranged on the first mounting frame 5; one end of a push rod 8 is arranged at the extended end of the first telescopic member 7, and the other end of the push rod 8 abuts against the part of the sealing plug 6 extending from the fan-shaped bottle 3.

After the sample liquid is released once, the top rod 8 is moved away from the sealing plug 6, the pure water source is opened, and the pure water is allowed to flow out from one end of the top rod 8 through the first water trough 801 to clean the surface of the top rod 8 and the liquid guide groove 4. The fan 9 is installed inside the liquid guide groove 4. After the top rod 8 and the liquid guide groove 4 are cleaned with pure water, the fan 9 is started to blow the top rod 8 and the liquid guide groove 4 dry to prevent residual liquid from contaminating the next sample liquid.

[0050] Furthermore, the fan-shaped bottle 3 has a first liquid inlet 302 at the top, and also includes a liquid inlet pipe 10, which is arranged on the first mounting frame 5, one end of the liquid inlet pipe 10 is connected to the liquid pump, and the other end of the liquid inlet pipe 10 is aligned with the first liquid inlet 302.

The liquid inlet pipe 10 is installed on the first mounting frame 5, and one end of the liquid inlet pipe 10 is connected to the liquid pump, and the other end is aligned with the first liquid inlet 302 at the top of the fan-shaped bottle 3. By controlling the operation of the liquid pump, the liquid sample can be accurately injected into the fan-shaped bottle 3 through the liquid inlet pipe 10. The design of the liquid inlet pipe 10 ensures the smoothness and accuracy of the sample injection process, and avoids sample contamination or loss that may be caused by manual operation. The standardization and automation of sampling work are further improved.

[0052] Furthermore, it also includes a film 11, which has a cross opening. The film 11 is arranged in the first liquid inlet 302 to close the first liquid inlet 302; the second telescopic member 14 is arranged between the first mounting frame 5 and the liquid inlet pipe 10 to drive the liquid inlet pipe 10 to pass through the film 11.

[0053] In this embodiment, a film 11 is arranged in the first liquid inlet 302 at the top of the fan-shaped bottle 3, and the film 11 has a cross opening, which is used to close the first liquid inlet 302 to prevent the sample liquid from leaking in a non-sampling state. The cross opening opened on the film 11 facilitates the passage of the liquid inlet tube 10. The second telescopic member 14 is arranged between the first mounting frame 5 and the liquid inlet tube 10. By controlling the expansion and contraction of the second telescopic member 14, the liquid inlet tube 10 can be driven to pass through the cross opening of the film 11 to realize the operation of injecting the liquid sample into the fan-shaped bottle 3. After the sampling is completed, the second telescopic member 14 contracts, the liquid inlet tube 10 withdraws from the film 11, and the film 11 closes the liquid inlet again to ensure the sealing of the sample during storage.

[0054] Furthermore, it also includes a first driving member 12, which is disposed on the frame housing 1 and is used to drive the rotating disk 2 to rotate.

The mounting grooves 201 are evenly arranged along the central circumference of the rotating disk 2. This layout ensures that each fan-shaped bottle 3 always maintains a constant relative position with respect to the rotating axis of the rotating disk 2 when the rotating disk 2 rotates, which is convenient for the operator to observe and operate.

[0057] Furthermore, it also includes a support member 13, which is arranged between the rotating disk 2 and the frame shell 1 to stabilize the rotation of the rotating disk 2.

[0058] In this embodiment, the support member 13 is disposed between the rotating disk 2 and the frame housing 1 to provide additional support and stability, ensuring that the rotating disk 2 can maintain stable operation when rotating at high speed or when the load changes, and avoiding vibration or shaking that affects the sampling accuracy and equipment life, thereby improving the overall performance and operational convenience of the sampling device.

[0059] Furthermore, it also includes a leak-proof member 15, which is arranged in the fan-shaped bottle 3, and has a second liquid inlet 1501, which is connected to the first liquid inlet 302, and the cross-sectional area of ​​the second liquid inlet 1501 gradually decreases. The working principle and beneficial effects of the utility model are as follows:

[0060] In this embodiment, the bottle mouth seal can also be achieved by adding a leak-proof component 15 in the fan-shaped bottle 3. The leak-proof component 15 has a second liquid inlet 1501, and the second liquid inlet 1501 is connected to the first liquid inlet 302. The cross-sectional area of ​​the second liquid inlet 1501 gradually decreases. The advantage is that when the fan-shaped bottle 3 is accidentally overturned, the outflow of sample liquid in the fan-shaped bottle 3 can be reduced.

[0061] Furthermore, it also includes a bottle cap 16 , which is arranged on the first liquid inlet 302 .

[0062] In this embodiment, the purpose of providing the bottle cap 16 is to perform secondary sealing when the fan-shaped bottle 3 is removed. When the fan-shaped bottle 3 is on the rotating disk 2 for normal use, the bottle cap 16 is not installed on the fan-shaped bottle 3.
