The end of the threaded sleeve near the piston plate has a threaded post that is fixedly connected to the piston plate in a horizontal direction, and the threaded post can be hidden inside the threaded sleeve. The driving component is installed in the mounting cavity and connected to multiple threaded sleeves. The driving component is used to make the multiple threaded sleeves rotate synchronously in multiple mounting holes.

3. The sampling device for detecting wastewater discharge from a ship according to claim 2, characterized by: The driving component includes a mounting plate fixedly installed in the mounting cavity by screws, a vertical rotating rod rotatably mounted on the mounting plate, the rotating rod being connected to multiple threaded sleeves through multiple sets of bevel gear assemblies, and a motor for driving the rotating rod to rotate is fixedly mounted on the mounting plate.

4. The sampling device for detecting wastewater discharge of a ship according to claim 1, characterized by: The positioning mechanism includes clamping plates that are symmetrically and horizontally slidably installed on the bottom of the fixed plate. The two clamping plates are located on both sides of the fixed column. A horizontally oriented bidirectional threaded rod is rotatably installed on the fixed plate, and the bidirectional threaded rod is threadedly connected to both clamping plates.

5. The sampling device for detecting wastewater discharge of a ship according to claim 4, characterized by: Both clamping plates have V-shaped clamping grooves on their sides that are close to each other.

6. The sampling device for detecting wastewater discharge of a ship according to claim 1, characterized by: A liquid-passing pipe connected to the sampling hole is fixedly installed on the side of the fixed column near the sampling hole.

7. The sampling device for detecting wastewater discharge of a ship according to claim 6, characterized by: The fixing column moves vertically through the inside of the through hole. A fixing mechanism is installed on the top of the fixing plate to fix or remove the fixing between the fixing column and the fixing plate. A clearance hole is opened on the inner wall of the through hole near the sampling hole, and the liquid tube can move through the clearance hole.

8. The sampling device for detecting wastewater discharge of a ship according to claim 7, characterized by: The fixing mechanism comprises a fixing frame fixedly installed on the top of the fixing plate and located on one side of the through hole, a limiting hole is linearly arranged in a vertical direction on one side of the fixing frame close to the fixing frame, a fixing rod is movably and vertically arranged on the fixing frame, the end of the fixing rod is inserted into the limiting hole and is clamped with the fixing column, a limiting plate is fixedly installed on the outer side wall of the fixing rod and located on the inner side of the fixing frame, and a spring is installed on the outer side of the fixing rod and located between the limiting plate and the inner wall of the fixing frame away from the fixing column.
