[0015] The principle and beneficial effects of this technical solution: (1) The sampling assembly provided in the present invention can collect water samples and sediment samples at the same time in one sampling operation. When sampling operation is required, the guide assembly is first unfolded by the guide assembly, and then the water sampling tube is lowered to a suitable position along the placement hole by the traction assembly, so that the emitter at the bottom of the water sampling tube is slidably connected with the guide assembly, and then the water sampling tube is continued to be lowered along the placement hole. After the water sampling tube moves to the sampling depth, the air pump at the top of the water sampling tube is driven to pump air, so that the folding air cushions provided in the sampling window located at the highest layer are folded at the same time. At this time, the sampling window is opened, and the water sample will flow into the water sampling tube from the sampling window. After a period of time, the air pump deflates, and all the folding air cushions located at the highest layer will expand synchronously, so that the sealing plate is re-stuck in the sealing groove to seal the water sampling tube and end the sampling at the current depth. Similarly, when sampling deeper water bodies, the sampling windows of different levels are opened from top to bottom in sequence to carry out water sampling until the sampling of water bodies at different depths is completed.

[0016] (2) The guide assembly provided in the present invention can guide the movement of the water sampling tube. When the guide assembly is unfolded, the telescopic rod in the guide assembly is first shortened to rotate the first guide rail at the bottom end of the floating plate. When the telescopic rod slides to one end of the slide groove, the first guide rail will synchronously rotate to the vertical direction. At this time, the first motor needs to be rotated first. The first bevel gear connected to the output shaft end of the first motor will rotate the second guide rail fixedly connected to the second bevel gear. Since the bottom end of the second guide rail is hinged with the third guide rail, and the hinge axis of the first guide rail and the second guide rail is perpendicular to the hinge axis of the second guide rail and the third guide rail, the third guide rail will also rotate synchronously until the bottom end of the first guide rail is magnetically attracted to the top end of the second guide rail, and the output shaft of the second motor is driven to rotate. At this time, the third guide rail will rotate downward together with the fourth guide rail until the top end of the third guide rail is magnetically attracted to the bottom end of the second guide rail. At this time, the unfolding of the guide assembly is completed.

[0017] (3) The buoy and power assembly provided in the present invention can keep the floating plate floating on the water surface at all times, and can also enable the user to remotely control the movement of the floating plate on the water body. After the floating plate is moved to the sampling location by driving the pump and the positioning component, the sampling operation can begin. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The guide assembly can guide the movement of the water sampling tube 26. When the guide assembly is unfolded, the telescopic rod 9 in the guide assembly is shortened first. Since the telescopic rod 9 is connected to the control frame 13 through the connecting plate 12, and the bottom end of the control frame 13 is hinged to the connecting button 19 on the outside of the first guide rail 20, the telescopic rod 9 will slide along the slide groove 10 during the shortening process of the telescopic rod 9.

[0029] like Figure 1 As shown, two groups of buoys 6 are arranged outside the floating plate 3 , and the number of buoys 6 included in the two groups of buoys 6 is equal and symmetrically arranged on both sides of the floating plate 3 .

[0032] The specific usage and function of this embodiment are as follows: The sampling assembly provided in the present invention can collect water samples and bottom mud samples at the same time in one sampling operation.

After the water sampling tube 26 is moved to the sampling depth, the air pump 2 at the top end of the water sampling tube 26 is driven to pump air, so that the water sampling tube 26 at the highest layer is The folding air cushion 7 arranged in the sampling window 25 is folded at the same time, and the sampling window 25 is opened at this time, and the water sample will flow into the water sampling tube 26 from the sampling window 25. After a period of time, the air pump 2 will deflate, and all the folding air cushions 7 located at the highest layer will be expanded synchronously, so that the sealing plate is re-engaged in the sealing groove 24 to seal the water sampling tube 26 and end the sampling at the current depth. Similarly, when sampling deeper water bodies, the sampling windows 25 of different levels can be opened from top to bottom in sequence to carry out water sampling until the sampling of water bodies at different depths is completed; After completing the water sampling, the water sampling tube 26 is continuously lowered through the traction assembly until the water sampling tube 26 moves to the bottom end of the fourth guide rail 18. At this time, the sediment sampling tube 28 is launched downwardly through the launcher 27, so that the sediment sampling tube 28 moves downwardly and embeds into the sediment. When the sediment sampling tube 28 stops moving, the baffle 8 is driven by the driving rod to move from the vertical direction to the horizontal direction. After the movement is completed, the launcher 27 pulls the sediment sampling tube 28 outwardly through the pull rope.
