The invention relates to the technical field of underwater dirt suction devices, in particular to an underwater dirt suction device which comprises a dirt suction device body, the dirt suction device body comprises an axial flow pump and a dirt suction plate, and the axial flow pump comprises an impeller located in a water inlet pipe and driven by a brushless motor and a discharging inclined pipe obliquely communicated with the side wall of the water inlet pipe. The inner cavity of the water inlet pipe is internally provided with a pressure buffering air bag located above the lower end opening of the discharging inclined pipe, the pressure buffering air bag is externally connected with an adjusting ball capable of adjusting air pressure, and the lower end of the pressure buffering air bag is provided with a pressing plate installed on the inner wall of the water inlet pipe in a lifting mode. Under the driving adsorption of the motor, the water level in the water inlet pipe rises to the upper end of the discharging inclined pipe, a sealed environment is formed, then the pressure intensity of the pressure buffering air bag is adjusted through the adjusting ball, negative pressure is formed in the sealed environment, the water flow suction force is increased, and the sewage suction capacity is improved.
