A gear is rotatably installed inside the transmission frame. The gear meshes with a rack. A first motor is installed on the outer wall of one side of the transmission frame. The input end of the first motor is electrically connected to the output end of the microcontroller inside the controller. One end of the first motor extends into the interior of the transmission frame and is connected to one end of the gear. The first motor is configured to drive the gear to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the water quality stratification sampler not only expands the sampling range when the sampler is used, but also makes it easy to sample water sources at different depths, and ensures the sampling accuracy of the water source;

[0012] The base is moved by a multi-section electric push rod, which drives the limiting wheel to slide on the top of the limiting rail. The extension range of the multi-section electric push rod is set according to the length of the limiting rail to prevent the limiting wheel from falling off the top of the limiting rail. This allows for smooth adjustment of the sampling tube position to sample water sources in different areas, thereby expanding the sampling range of the sampler.

[0013] The first motor drives the gear to rotate. Because the gear and rack mesh with each other, the lifting sleeve slides up and down on the outer wall of the upper column to adjust the height of the sampling tube. Then, the second motor drives the roller to rotate, so that the side seat can wind and unwind the rope, which can further adjust the height of the sampling tube. This makes it easy to adjust the height of the sampling tube in two ways, thus making it easy to sample water sources at different depths.

[0014] The sampling tube is equipped with three sampling cylinders. When the sampling cylinder moves down to the specified depth of the water source, the corresponding solenoid valve is opened, allowing the water source at the current depth to flow into the sampling cylinder through the inlet pipe. Then the solenoid valve is closed, and the sampling operation of the water source at this depth is completed. This allows for the classification and storage of water sources at different depths, thereby ensuring the sampling accuracy of the water source. Attached Figure Description
