WATER TRANSPORT PROPULSOR Russian patent published in 2020 - IPC B63H1/36 F02B61/04 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding, namely, to water propulsors. Water transport propulsor comprises housing with anchor, cylinder, piston, transmission shaft and fins. Propulsor consists of frame with movably fixed on it by one conditional axis two running levers with fins, moving mechanism located on frame between travel levers at some distance from place of their attachment to frame, connected to them and providing them with simultaneous oscillatory movements of pendulum type in opposite directions. Housing of moving mechanism with fixed cylinder, in which the piston, cylinder and piston is located have a straight shape, piston is movably, with possibility of sliding, is connected with transmission shaft bracket. Shaft with the flywheel is movably with the presence of the gap and is connected to the top of the armature. Center of armature base is located on one conditional axis with flywheel shaft. Conventional axis of anchor pins coincides with the plane of its base and passes through the center of the anchor base, on the pins there is a clamp of the transmission shaft located horizontally on one conditional axis with the center of the anchor support perpendicular to the conditional axis of the flywheel shaft. Each of the clutches passes through one of two driving levers, the piston moves back and forth, the transmission shaft bracket and the anchor are rocking, the flywheel is top, the running levers with fins are pivoted through the transfer shaft in the plane perpendicular to the plane of the frame. Amplitude of running levers is adjusted by change of distance from central point between points of fastenings of travel levers to frame to connection points of travel levers with moving mechanism, as this distance increases amplitude of oscillations decreases, and when it decreases – increases.

EFFECT: simplified design and higher safety of water transport.
