[0025] Reference Figure 1-3As shown, a water quality testing sampling device has a drive motor 3 mounted on the top of a base plate 1. A rope-binding wheel 4 is sleeved at the output end of the drive motor 3, and a steel cable 5 is wound around the periphery of the rope-binding wheel 4. Two support columns 6 are fixedly connected to the top of the base plate 1. The main function of the support columns 6 is to bear the weight of the device, allowing it to be fixed in different environments without affecting the sampling operation. A first pulley 7 is provided between the two support columns 6. A mounting plate 8 is fixedly connected to the top of the support columns 6, and a rotating base 9 is fixedly connected to the top of the mounting plate 8.

One end of the steel cable 5 is fixedly connected to the collection mechanism 2. The collection mechanism 2 is placed into the water area, and after reaching a suitable depth, the drive motor 3 is turned off. At this time, the air pump 210 is started. In the sealed space, the air pump 210 draws air from the inside of the storage tank 203 through the air hole 209. As the piston 213 moves upward, the water to be tested enters the inside of the storage tank 203 through the water suction port 207. The water to be tested is filtered by the filter plate 208 to prevent impurities from entering the storage tank 203. At the same time, this device is equipped with multiple storage tanks 203, which can collect multiple parallel samples at the same time.
