Hull propulsion mechanism

A hull propulsion mechanism comprising:

• a ship body;
• a wind blade, which is set at the top of the ship body and has a plurality of sails for obtaining a rotating force from the wind blade;
• a shaft, which sustains the wind blade and is a rolling axis as well for conveying the rotating force by the wind blade;
• a water pump, which is a power unit that circulates water by making use of a turning force from the shaft;
• and
• an engine, which obtains hull propulsion from screws that are rotated by circulated water pressure from the water pump,
• wherein the engine comprising:
• a housing part, which is fixed to the bottom of the ship body and has a cylindrical shape;
• a screw, which is situated inside the housing part;
• and
• a pipeline for bursting water, which is pumped by the water pump, onto an outer surface of the screw,
• wherein the screw comprising:
• a screw drum part, which is a cylindrical part and rotatably fixed to an inner wall of the housing part via bearings;
• and
• a fin whose outer side is fixed to an inner wall of the screw drum part and the fin rolls with a rolling movement of the screw drum,
• wherein the screw drum part, which has a plurality of partitions having a convex shape on a peripheral outer surface and the partitions divide into many sections, wherein the plurality of partitions are arranged parallelly while intersecting a rotating direction of the screw,
• wherein the water pumped by the water pump is gushed onto the partitions via the pipeline leading the water to the peripheral outer surface of the screw drum part,
• wherein said water force makes the screw drum part and the fin integrally rotating.
