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
The present invention relates to a kind of electromagnetic piston propelling unit.Be applicable to ship power.
Background technology
The marine propeller of current use mostly is propeller type, and it is rotated by screw propeller and produces vectored thrust in water.It is limited that reason due to structure improves water discharge pressure.
Summary of the invention
The invention provides a kind of electromagnetic piston propelling unit, it is closed one of a piston barrel with umbrella hat, an other cylindrical shell connecting reducing type spout composition, and inner at piston barrel is linear electric motors and piston two parts by baffle for separating; Under the shifting magnetic field effect produced at the stator coil that is energized by the fabricate block of linear motor rotor warp beam and piston, crank motion makes piston carry out the operation of water suction setting-out discontinuously.Due to current, to be bound in the loss of piston barrel self-energy little, and hydraulic pressure is high.
The present invention realizes with following technical scheme: a kind of electromagnetic piston propelling unit, comprises cylindrical shell, piston that the linear electric motors be sleeved in cylindrical shell are connected with linear electric motors center shaft, the check valve of water drainage that is arranged on dividing plate between linear electric motors and piston, is arranged on piston barrel between dividing plate and piston;
It is characterized in that: described cylindrical shell is made up of umbrella hat, piston barrel, reducing type nozzle; The pressure of water injector can be improved due to reducing type spout but the speed of water inlet can be affected, in order to ensure water intake velocity, be distributed with multiple auxiliary water inlet at cylindrical shell radial face, auxiliary water inlet is closed by piston or is opened when crank motion, and namely piston has the effect of switch valve concurrently; The magnet coil of described linear electric motors is fixed on piston barrel inwall as stator, and its mover is stacked to be sleeved on a center shaft by multi-disc ring-shaped silicon steel sheet and forms, and circular shaft mouth is connected with piston centre through dividing plate; Described dividing plate is shaped with centre hole, and dividing plate radial face is connected with piston barrel inner wall sealing, and dividing plate centre hole is embedded with seal ring and infiltrates magnet coil for the slipper seal of straight-line electric arbor for anti-sealing and affect propelling unit and normally work; The piston barrel place that described check valve is arranged between dividing plate and piston seeps water for discharging piston; Described control circuit is that solenoid generation travelling-magnetic-field acts on stator, makes stator drag reciprocating motion of the pistons.
Good effect of the present invention
1. utilize reciprocating motion of the pistons and aqueous phase mutual effect to produce thrust and there is no water resistance.
2. during return piston stroke, there is the impact force action of current to make power consumption play power savings less in piston.
3. can many distributions simultaneously or be used alternatingly and can reduce pulsation and export.
4. use electric energy that electric frequency only need be regulated to realize infinite speed variation.
5. do not have noise during work, mechanical vibration are little.
6. structure is simple, except other part of electromagnet portion can use the non-metallic material manufactures such as plastics.
