Description

The electromagnetic force ship

Technical field

The utility model relates to the Ship Propeling technology, and particularly a kind of electromagnetic force 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 electromagnetic force ship, makes its driving shaft and propelling screws or hydraulic propeller realize that noncontact seals transmission fully, is intended to overcome the above-mentioned defective of existing vessel.

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 non magnetic pipeline constitute, pipeline connects with hull; At the fixed rotor magnetic guiding loop of impeller (or propeller) periphery of rotor like the square gear-like, the cylindrical of rotor magnetic guiding loop leaves circle one gap in the pipeline, fixed stator on the pipeline cylindrical, described rotor and control system constitute a kind of special reluctance motor, and the axle of rotor is support and the stator assembling and positioning of axle by being provided with in bearing and the pipeline of impeller; Control system is made up of some rotor-position sensors and controller, and transducer is fixed on the end face of the support of stator.

Control system loop control stator coil sense of current and break-make regularly, rotor just is driven in rotation, impeller rotation as a result, to the stator precession, stator is carded to direct current with the precession current with ducted water, from the tail mouth ejection of pipeline, thereby produce and regurgitate power, push boat and advance.

The utility model has following advantage:

1. there is not transmission device, simple in structure, energy-conservation, reliability height, efficient height;

2. sealing does not fully have and leaks environmental protection;

3. non-maintaining, the life-span is long.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Show as Fig. 1 Fig. 2.Hull is a part 1, and shell is a part 2; The pipeline of hydraulic propeller is a part 3, and the metal material of pipeline 3 usefulness high resistivities or nonmetallic materials are made; The impeller 17 (screw) of hydraulic propeller is fixed in the rotating shaft 6, be consolidated in the periphery of impeller 17 like the rotor magnetic guiding loop 12 of square gear-like, the cylindrical of rotor magnetic conductivity ring 12 leaves interior circle one gap of pipeline 3, and non

magnetic rectification circle

10 and 15 is consolidated in the end face of rotor magnetic guiding loop 12; On the right-hand of impeller 17 is stator, by magnetic bearing (or other bearing) 5,

stator support

4 and 7 fixed compositions of blade, magnetic bearing 5 and 18 inner ring and rotating shaft 6 are fixing, the mesopore of the outer ring of magnetic bearing 5 and stator support 4 is fixed, the mesopore of the outer ring of magnetic bearing 18 and support 20 is fixed, and the cylindrical of stator support 4 and support 20 and the interior circle of pipeline 3 are fixed; Stator is similar to the stator of common electric machine, the stator core 14 that builds up by silicon steel sheet, enameled wire loop 11, strip permanent magnet 20,

stator cylinder

9 and 16 fixed compositions of disk, enameled wire loop 11 surrounds the tooth of stator core 14, the length direction of strip permanent magnet 20 is along the axis direction of armature spindle 6, and be embedded in axisymmetrically among the stator core 14, strip permanent magnet 20 can improve the operating efficiency of device, stator is fixed on the cylindrical of pipeline 3, and the end face of stator core 14 is alignd with the end face of rotor magnetic guiding loop 12, guarantee that armature spindle 6, rotor and stator are coaxial; Control system is made up of some rotor-position sensors 8 and controller 13, and transducer 8 is fixed in the end face of stator support 4.Rotor magnetic guiding loop 12 designs definite with the number of teeth and the groove number of stator core 14 according to actual needs.

The magnetic line of force of magnet always tries hard to walk the path closure of magnetic resistance minimum, and this is a magnetic characteristic of magnet, at this, is called magneto resistance effect.When described hydraulic propeller is worked, controller is according to the information of the relative position of the tooth of transducer 8 detection rotor magnetic guiding loops 12 and the number of teeth of stator core 14 (part of pressing from both sides between stator two wire casings), the coil electricity that some tooth rim of stator is enclosed, these teeth become electromagnet, the wall that its magnetic line of force passes pipeline 3 immediately is along circumferentially attracting on the rotor magnetic guiding loop from their teeth of (the near more magnetic resistance of distance is more little) recently, desire to make the radial symmetric center of these teeth on the rotor magnetic guiding loop to overlap, thereby rotor is produced torque with the radial symmetric center of stator core 14 teeth of hot-wire coil encirclement.The relative position information of the tooth of transducer 8 detection rotor magnetic guiding loops 12 and the tooth of stator core 14 is also passed to controller 13, and the control system loop control feeds the stator coil 11 sense of current and break-make regularly from driving power, and rotor just is driven in rotation.To the stator precession, stator is carded to direct current with the precession current to impeller 8 with the water in the pipeline 3 as a result, from the tail mouth ejection of pipeline 3, regurgitates power thereby produce, and pushes boat and advances.
