[0022] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, the surface water quality analysis sampling device of this practical design includes a main frame 1, and floating boxes 2 are provided on both sides of the main frame 1; a vertical frame 3 is assumed to be provided on the main frame 1, and a vertical guide cylinder 4 is provided on the vertical frame 3, and a water quality sampling tube 5 is provided in the guide cylinder 4; the main frame 1 is also provided with a sampling water tank 6 and a water pump 7 along one side of the guide cylinder 4; the water inlet and the outlet of the water pump 7 are connected to the water quality sampling tube 5 and the sampling water tank 6 respectively through water pipes.

[0024] The entire device is supported by a main frame 1, while a flotation tank 2 maintains stability on the water surface. A guide tube 4, mounted on a vertical frame 3, provides vertical guidance for a water sampling tube 5. A water pump 7 connects the water sampling tube 5 to a sampling tank 6 via a water pipe, extracting water samples from the tube and transferring them to the sampling tank 6 for storage and analysis.

[0025] As an embodiment, a joint 6.1 detachably connected to a water pipe is provided at the water inlet of the sampling water tank 6.

[0026] Specifically, the sampling water tanks 6 are arranged in multiple groups at intervals, and the main frame 1 is provided with fixing parts 8 for fixing the sampling water tanks 6.
