Abstract

The invention discloses an electromagnetic piston propeller, and relates to ship power. The electromagnetic piston propeller has the advantages that a piston can do work in a reciprocating manner by the aid of electromagnetic force, so that water which flows into a piston barrel can be discontinuously drained, and reacting force can be generated; one end of the piston barrel is closed by an umbrella-shaped cap, the other end of the piston barrel is connected with a barrel which comprises a necked nozzle, and the inside of the piston barrel is divided into two portions for a linear motor and the piston by a partition plate; a rotor of the linear motor can reciprocate via a combination of a shaft and the piston under the effect of movable electromagnetic fields generated by an electrified stator coil, so that the piston can discontinuously carry out water suction and pressurization operation; water flow is constrained in the piston barrel, and accordingly the electromagnetic piston propeller is low in energy loss and high in water pressure.

Description

technical field [0001] The invention relates to an electromagnetic piston propeller. Suitable for ship power. Background technique [0002] Most of the ship propellers currently used are propeller type, and the propeller rotates in water to generate vector thrust. Due to structural reasons, the increase in drainage pressure is limited. Contents of the invention [0003] The invention provides an electromagnetic piston propeller, which is a cylinder composed of one end of a piston cylinder closed with an umbrella cap, and the other end connected with a shrinking nozzle. The piston cylinder is separated into a linear motor and a piston by a partition. Two parts; the combination of the linear motor mover warp shaft and the piston reciprocates under the action of the moving magnetic field generated by the energized stator coil, so that the piston performs the water suction and pressure operation intermittently. Because the water flow is bound in the piston cylinder, the ene...
