Abstract

The utility model discloses a magnetic energy vessel, comprising a water jet propeller, and a vessel body; wherein, the water jet propeller comprises a stator, a rotor, a control system, and a pipeline. The utility model is characterized in that: the pipeline is connected with the vessel body; a circular ring with a plurality of permanent magnetic poles is fixedly connected on the circumference of the impeller of the rotor, the stator is fixed on the excircle of the pipeline, and a plurality of teeth enclosed by an enameled wire are arranged in the iron core of the stator, so as to form the magnetic poles. The stator, the rotor and the control system form a special motor; wherein, the control system comprises rotor position sensor, a controller, an accumulator, and a rectifying voltage regulator; according to the position signals of the rotor magnetic poles relative to the stator iron core teeth, the controller fetches power from the accumulator and regularly supply power to each group of coils of the stator; therefore, the stator will rotates because the permanent magnetic poles are under the actions of the attractive force moment and the repulsive force moment of the magnetic poles of the stator teeth, thus the impeller is driven to propel the vessel forward, and drives the generator of the motor to generate power, which is then stored into the accumulator by means of the rectifying voltage regulator.

Technical field

The utility model relates to the Ship Propeling technology, and particularly a kind of magnetic energy advances ship.

Background technology

The engine of existing vessel passes dividing plate by power transmission shaft and directly drives propelling screws or hydraulic propeller, power transmission shaft and dividing plate seal with encapsulant, when rotating, power transmission shaft takes place acutely to rub with encapsulant, encapsulant is fragile, cause seepage or emit leakage, can make the lubricating oil or the waste oil of mechanical device in interior water inlet of ship or the ship leak into the outboard contaminated environment, vibration and noise are arranged during transmission, and friction meeting power consumption is living hot, reduces the mechanical efficiency of ship.In addition, the obturator workload of change damaging big, bother, delay production.

Summary of the invention

The utility model discloses a kind of magnetic energy ship, designs a kind of hydraulic propeller, utilizes electromagnetic energy and permanent magnetism to drive, and is intended to overcome the above-mentioned defective of existing vessel, and energy-conservation.

The utility model is realized by following technical scheme.

The utility model is made of hydraulic propeller and hull, hydraulic propeller by stator, rotor, control system, and pipeline constitute, pipeline connects with hull; The fixed annulus that some permanent magnetism magnetic poles are arranged of impeller (or propeller) periphery at rotor, fixed stator on the pipeline cylindrical, stator core has some teeth that surrounded by enameled wire loop, form electromagnetic pole, described rotor and control system constitute a kind of special machines, control system is by rotor-position sensor, controller, storage battery and rectification voltage regulator are formed, controller measures the position signalling of rotor magnetic pole with respect to stator core tooth according to transducer, respectively organizing coil for stator from the storage battery power taking switches on regularly, then rotor be subjected to because of its permanent-magnet pole stator tooth electromagnetic pole attraction moment and repel moment and rotate, thereby drives impeller is pushed boat and is advanced, and the generator for electricity generation of drive motors, the electricity that sends deposits storage battery in through rectification voltage regulator.

Suppose the rotor that the permanent magnetism magnetic pole of the rotor of the motor portion of described motor is made plurality of teeth with pure soft iron is replaced, its operation principle is very similar to switched reluctance machines so, disregard loss, the electric energy that switched reluctance machines output energy equals to import, not energy-conservation.And the utility model makes the rotor permanent-magnet pole obtain the repulsion square that electromagnetic pole of corresponding stator attracts moment and another electromagnetic pole simultaneously, and gravitation square or repulsion square provide jointly by electromagnetic field and permanent magnetic field; Switched reluctance machines only is the soft iron tooth of its rotor of electromagnetic attracting force of stator tooth, and this gravitation is only provided by electromagnetic field.So the motor output energy of motor of the present utility model is greater than the electric energy of need input.Square being directly proportional of magnetic flux density between the electromagnetic pole of the motor stator of motor of the present utility model and the rotor permanent-magnet pole in amount of force and the gap between them, and the superposition value that this magnetic flux density value is electromagnetic pole and permanent-magnet pole magnetic flux density, if keep this value constant, improve the magnetic flux density value of permanent-magnet pole in described gap, reduce the magnetic flux density value of electromagnetic pole in described gap equally, then described motor machine output energy value is constant, but reduced the electric energy of required input significantly, energy output input difference becomes big in other words.So the ingenious use permanent magnetism of the utility model physical efficiency, make energy increment, and increment increases substantially with the enhancing of permanent magnetic field, most of outwards output of this value-added energy drives the impeller of described hydraulic propeller, fraction is used for described generator for electricity generation, to support described motor operation.

It should still be noted that, electric motor structure of the present utility model and operation principle and magneto (detail knowledge can with reference to interrelated data) have substantial different, magneto utilizes the rotary electromagnetic field of stator to interact with the rotor field of containing permanent magnet and drives rotor, be based on electromagnetic induction principle, and motor of the present utility model is based on gravitation between electromagnet and the permanent magnet and repulsion.Permanent magnet motor stator electromagnetic force and rotor permanent magnetism power are big not as of the present utility model to the torque that its rotor produces, reason is that this stator electromagnetic force only produces the gravitation square to rotor, and the rotor permanent-magnet pole of the utility model motor is subjected to the attraction moment and the repulsion moment of the electromagnetic pole of corresponding stator tooth simultaneously.The rotary electromagnetic field of permanent magnet motor stator can induce eddy current and cause energy loss in rotor core and permanent magnet, and eddy current gives birth to heat and work the mischief, and rotary electromagnetic field also can produce magnetic hysteresis loss in rotor core.And the magnetic line of force that the stator field of the utility model motor enters rotor is seldom, in rotor induction very weak, so the utility model is energy-conservation significant more than magneto.

The utility model has following advantage:

1, fully permanent magnetism can be converted to the directly mechanical energy of actual use, the energy of permanent magnetic energy machine output is significantly rised in value than the energy of importing, thereby the utility model power consumption seldom, loss is little, and is energy-conservation, and efficient is high, and operating cost is very low;

2, the utility model generation power and drives impeller occur in described control system and rotor simultaneously, and have only movement parts of rotor, and be simple and compact for structure, so reliability is very high, and low cost of manufacture;

3, sealing fully do not have to be leaked, and does not produce pernicious gas, vibrates for a short time, and noise is little, and it is less to generate heat, environmental protection.
