Wide river surface section water sample automatic collection ship

The invention discloses a wide river section water sample automatic collection ship which comprises a ship body, a water pumping bin, a water storage bin, a program control bin, a power bin, a bin door, a handle, a linkage mechanism, a remote controller and two propellers. The propeller rotates to drive the first gear to rotate, the first gear rotates to drive the half gear to rotate, the half gear rotates to drive the rotating shaft to rotate, the rotating shaft rotates to drive the transmission wheel to rotate, the transmission wheel rotates to drive the transmission belt to drive the other transmission wheel to rotate, and the other transmission wheel rotates to drive the second gear to rotate. The second gear rotates to drive the linkage rack to slide, and the linkage rack slides to drive the wedge-shaped block to move synchronously; the moving speed of the wedge-shaped block is changed in real time through the rotating speed of the propeller, so that water inlets of different water storage boxes can be o
