Water quality monitoring ship

The invention relates to the technical field of water quality monitoring, in particular to a water quality monitoring ship which comprises a bearing assembly, a floating assembly and a lifting assembly, the bearing assembly comprises a ship body part, a driving part and a water quality monitor, the floating assembly comprises a rolling part, a buoyancy part and a limiting part, and the lifting assembly comprises a supporting part and a shell part. According to the water quality monitoring boat, the rolling pieces, the buoyancy pieces and the limiting pieces are arranged, so that the water quality monitoring boat can move on the shore by means of the wheels, the wheels can be retracted by means of buoyancy of water after the boat is driven into the water, and therefore resistance of the boat is reduced, and the situation that an operator gets close to a water source and falls into water in a slipping mode is avoided; according to the water quality monitoring device, the effect that a small boat can perform lar
