[0025] Please see Figure 1, Figure 2 , Figure 3 , Figure 4 An auxiliary limiting mechanism 12 is provided on both the rear support plate 7 and the take-up reel 9. The auxiliary limiting mechanism 12 includes a limiting hole 121. The end face of the take-up reel 9 is provided with the limiting hole 121. A limiting rod 122 is slidably connected to the inner wall of the rear support plate 7. The limiting rod 122 is slidably connected to the limiting hole 121. A spring 123 is provided on the outer side of the limiting rod 122.

The counterweight 131 is fixedly connected to the lower end of the sampling cylinder 11. Two filter screens 132 are fixedly connected to the flow hole of the sampling cylinder 11.

[0027] The specific implementation process of this utility model is as follows: In use, the electromagnet 125 is activated to magnetically attract the iron disc of the limiting rod 122, thereby pulling the limiting rod 122 to move, causing the spring 123 to deform, and finally causing the limiting rod 122 to disengage from the limiting hole 121. The servo motor 8 is activated to drive the output shaft to rotate, thereby driving the winding wheel 9 to rotate, and the traction line 10 is unloaded. Under the action of the guide wheel 5 and the guide wheel 6, the movement of the traction line 10 is kept stable. The sampling cylinder 11 is lowered so that it can enter different layers of water for sampling. When the sampling cylinder 11 moves to the destination, the servo motor 8 and the electromagnet 125 are turned off, causing the spring 123 to recover its deformation, thereby pulling the limiting rod 122 to insert into the limiting hole 121, and providing auxiliary support for the winding wheel 9 to ensure the stability of the overall structure.

[0028] The micro submersible motor 136 is started to drive the output shaft to rotate, which in turn drives the screw 137 to rotate. With the threaded connection, the moving plate 134 can be driven to slide along the vertical part of the mounting bracket 133 to ensure the stable movement of the moving plate 134. This, in turn, drives the plug 135 to move upward, so that the plug 135 is disengaged from the flow hole of the sampling cylinder 11, and then the water is sampled for use. With the action of the filter screen 132, the water can be pre-filtered.
