Described end cap pulley 21 is similarly conventional pulley wheel, and diameter is the half of the diameter of motor shaft pulley 20, by hinge on the hanger of sleeve end cap 23.This end cap pulley 21 can be serving 22 and leads.Described serving 22 is conventional rope, and any lies on motor shaft pulley 20, and the other end walks around the end cap pulley 21 of guiding, and lies in coil tension spring 18 one end of withstanding the first extension sleeve 14 through sleeve end cap 23.Serving 22 under the control controlling motor 19, and then can control the flexible of extending means.
Described coil tension spring 18 is Conventional springs, and normal length is the twice of extending means spread length, and external diameter is identical with the second extension sleeve 15 internal diameter.Coil tension spring 18 is positioned in extending means, and the first extension sleeve 14 is withstood in one end, and the other end withstands sleeve end cap 23.Under the stretching of serving 22, spring is in compressive state always.Control serving 22 by control motor 19 to stretch, control the collapsing length of coil tension spring 18, and then control extending means stretching, extension.
Described generator 29 is embedded integration permanent magnet generator, and voltage rating is 24V, is made up of permanent magnet rotor 25, wound stator 26.In described permanent magnet rotor 25, magnetic pole adopts NdFeB33UH magnet steel, and number of pole-pairs is 8.The inner core that this permanent magnet rotor 25 is fixedly mounted on impeller housing 11 together rotates with impeller housing 11, extending means.
Described wound stator 26 coiling adopts Y shape, double-deck whole apart from lap wound connection.Parallel branch number on wound stator 26 is 1, and groove number is 48, and coil pole span is 3, and coil pitch is 3.Armature stamping on wound stator 26 adopts 35W310 material.Described wound stator 26 is fixedly mounted on central shaft 27.
When permanent magnet rotor 25 is together rotated with electricity generating device support, cutting wound stator 26, thus produce induction electromotive force.
During work: when submarine navigation device is in resident state, before and after submarine navigation device, section anchor chain 8 drops into seabed, makes aircraft horizontal stable resident, keeps electricity generating device impeller axis horizontal.Control motor 19 and discharge the serving 22 be wrapped on motor shaft pulley 20, coil tension spring 18 is stretched, under spring promotes, level Four bush connecting rod extends aircraft together with blade 13.Blade 13 is at incoming flow v
∞under impact, blade 13 rotates, when turning to different orientations around central shaft O
time, the lift L suffered by blade 13 is different with resistance D, L and D is decomposed into along the tangential force of blade 13 chordwise and the axial force perpendicular to chordwise, and wherein, tangential force is the driving force promoting axis of rotation.So, blade 13, extending means and electricity generating device support rotate around submarine navigation device longitudinal axis, thus the permanent magnet rotor 25 on embedding electricity generating device rack ventilating hole inwall is together rotated, cutting wound stator 26, produce induction electromotive force, thus be mechanical energy by the kinetic transformation of ocean current, then be electric energy by changes mechanical energy, for submarine navigation device.
