The invention discloses a buoys-type spiral cavity propeller and a boat with a propeller. The propeller comprises a spiral cavity, wherein a shaft hole is formed in a shaft center of the spiral cavity; a multi-thread helical blade is arranged at the periphery of the spiral cavity; a spiral blade cavity is arranged inside the spiral blade; the boat comprises a boat body, a tail vane, a power device and a transmission mechanism; the tail vane is arranged at the tail end of the boat body; the power device is arranged on the boat body; two parallel buoys-type spiral cavity propellers in the front axial direction and the back axial direction are symmetrically arranged on the two sides of the lower part of the boat body; main shafts of the buoys-type spiral cavity propellers are connected to the lower part of the boat body by the support in a rotating mode; and one end of each main shaft is in transmission connection with the power device by the transmission mechanism. The buoys-type spiral cavity propeller has the advantages that the propeller has a simple structure, is totally sealed, can generate buoyancy and power, can greatly reduce the resistance of water-level traffic tools, improves the driving speed of the water-level traffic tools, and saves energy sources and manpower.
Description
technical field [0001] The invention relates to a floating spiral cavity propeller and a ship equipped with the propeller, which can be used for water surface vehicles or small pleasure boats. Background technique [0002] At present, the general water surface vehicle has a large resistance on the water surface, and the driving needs to overcome this resistance, which affects the driving speed and wastes power energy. Contents of the invention [0003] The object of the present invention is: in order to overcome the above-mentioned deficiencies, provide a kind of propeller of floating spiral cavity and the boat that is installed with this propeller, overcome the shortcoming of the resistance of water surface vehicle, thereby improve the running speed of water surface vehicle, save power energy. [0004] The technical solution of the present invention is: a floating propeller with a spiral cavity, which is characterized in that: it includes a spiral cavity, and a conical t...
