[0003] In order to ensure the accuracy of the test results, it is necessary to collect river water samples at different locations and depths. The existing water quality sampling method is usually for the sampling personnel to stand on the shore to collect water samples near the shore. When collecting water samples far away from the shore, it is necessary to use a telescopic rod to drive the sampler to extend a certain distance to take samples. This sampling method not only has low sampling efficiency, but also has a small sampling range.

[0042] Specifically, the horizontal output pulley 433 and the first drive pulley 411 are connected by several steel ropes; the vertical output pulley 434 and the second drive pulley 422 are connected by several steel ropes to prevent the horizontal output pulley 433, the vertical output pulley 434, the first drive pulley or the second drive pulley 422 from slipping, causing the sampling component 30 to be misplaced.
[0043] The drive motor 431 is used to provide power to the gearbox 432, and the gearbox 432 is used to drive the first drive pulley 411 to rotate through the horizontal output pulley 433.
