[0012] By setting up a sampling device consisting of a sampling bucket, a counterweight plate and an opening and closing component, the sampling device can sample water samples in deep water areas, so that testers can test the water quality in deep water areas. When sampling water in deep water areas, the sampling device consisting of the sampling bucket, the counterweight plate and the opening and closing component can be vertically placed into the water by grabbing the rope. When the counterweight ring on the opening and closing component contacts the bottom of the water, the opening and closing component will stop sinking. At this time, the sampling bucket can be lowered further by the rope, so that the opening and closing component and the sampling bucket will move relative to each other. When the upper end of the sealing cover is After contacting the top wall of the barrel body, the sealing cover will be above the water inlet, so that the water in the deep water area will flow into the barrel body below the sealing cover through the water inlet. When the water sample is collected, the sampling barrel will be pulled up by the rope. At this time, the sampling barrel will move up, and the opening and closing assembly will remain stationary. When the barrel body contacts the bent part of the connecting rod, the sampling barrel will move up with the opening and closing assembly, and the sealing cover will be below the water inlet. At this time, the barrel body will be closed by the sealing cover until the sampling device is removed from the water body, and finally the water sample can be taken out of the barrel body for testing.
