The current water driving of the vehicle is mainly performed by the crawler belt of the chassis part, the water driving capability is very low, and the water driving is fastest and can only approach to 5km/h at present through matching modeling and upgrading the crawler belt. In addition, the fixed water propeller is additionally arranged at the tail part of the vehicle body by manufacturers, and through analysis, the propulsion efficiency of the propeller is greatly reduced due to the existence of vortex at the tail part of the vehicle body by the vehicle body modeling, so that the method is not a good solution.
