The invention discloses a water jet propulsion device. The water jet propulsion device comprises an electric motor, a transmission shaft, a propeller and a power unit housing; The output shaft of themotor is connected with the propeller through the transmission shaft; The power unit shell is provided with a through hole in the middle, and the two ends of the through hole are respectively providedwith a first cavity and a second cavity. The output shaft of the motor is sealed in the first cavity, the transmission shaft passes through the through hole, and the propeller is arranged in the second cavity. A water inlet is provided on the side walls of the second cavities on both sides of the through hole, and a water outlet is provided on the side of the second cavity away from the through hole. The water jet propulsion device of the invention can be separated from the cooling function of the cooling device, and the running time of the water jet propulsion device is improved.
Description
technical field [0001] The invention relates to the technical field of water surface vehicles and underwater vehicles, in particular to a water jet propulsion device. Background technique [0002] As a power device on the water surface or in the water, the water jet propulsion device is mostly used in surface vehicles, small unmanned boats, etc. With the development of industries such as sea surface operations, submarine operations, and seaside island tourism, the demand for surface vehicles or small unmanned boats is increasing day by day, and at the same time, higher requirements are put forward for water jet propulsion devices. [0003] figure 1 It is a structural diagram of a traditional water jet propulsion device. see figure 1 , the motor in the traditional water jet propulsion device is sealed inside the base body, and a cooling device is arranged around the motor to cool down the motor. The output shaft of the motor is connected with the paddle outside the base b...
