Drive control device controls motor work, and motor drives drive rod movement, and drive rod drives rotating arm rotary motion, makes
Sealing of hole cover board in opened condition, makes propeller stretch out cavity.
When needing propeller to work, the drive rod that drive control device controls electric cylinder stretches out, and pushes rotating arm rotation, will
Propeller is released outside hull, and propeller can carry out navigation and promote work at this time；Terminate when propeller works, the drive rod of electric cylinder
It retracts, propeller is withdrawn in the cavity of hull.
According to the above scheme, the rotating arm is V-shaped, and the hinge joint of rotating arm and the second hull pedestal is located at turning for rotating arm
Break；One end of rotating arm and one end of drive rod connect, and the other end of rotating arm is connect with propeller.
According to the above scheme, elastic stop is equipped in the cavity, and the elastic stop is located at the surface of propeller.When
When propeller is packed up, elastic bolster guide is in confined state, provides pretightning force, so that propulsion device mechanism is in tensioning state, mentions
The high reliability of propulsion device recycling in place, generates that abnormal vibrations are even unexpected to be opened when sealing of hole cover board being avoided to be motivated by fluid
It opens.
According to the above scheme, the electric cylinder includes motor, lead screw, cylinder body, nut, drive rod；The output shaft of the motor
It is connect with the intracorporal lead screw of cylinder；The nut is placed on lead screw, and is connect with drive rod；Motor drives guide screw movement, to make
Drive rod is flexible.Motor drives lead screw to make rotating motion, and the straight line of drive rod is converted to by the screw-driven of nut and lead screw
Movement.
According to the above scheme, the lead screw is the lead screw with self-locking function, makes electric cylinder at an arbitrary position can mechanical lock
Tightly, to avoid generation flow induced vibration.
According to the above scheme, the sealing of hole cover board and hull are conformal.When propulsion device is packed up, sealing of hole cover closure hull appearance
Face aperture, sealing of hole cover board and the conformal design of hull make hull outer surface keep fairing, effectively solve hull openings bring cavity
Noise problem, and reduce ship sailing resistance.
The beneficial effects of the present invention are:
It is closed at using electric cylinder, rotating arm, when propeller being made not work in hull cavity, and makes sealing of hole cover board by cavity
Closure of openings, to keep shape fairing；
There is only cable penetratings at one, eliminate crossing cabin transmission, i.e., no drive rod, fluid pressure line crossing cabin；Hull openings
Less, integrated horizontal high；Also the safety that Ship Structure is especially latent device application pressure-resistant cabin is improved；
Electric cylinder, rotating arm, propeller are placed in outboard arrangement, in order to install；
Propeller can folding and unfolding, withdrawal when not working avoids naval vessel or latent device and increases excrescence, influence navigation performance；
Shaftless propeller is selected, " propulsion electric machine-drive shaft system-propeller " is reduced to a motor and propeller is direct
Integrated integrated propeller, weight and size substantially reduce, can flexible arrangement in bow, stern etc., it is few to occupy aggregate resource；
It realizes mechanical interlocking and integrated sealing of hole cover closure hull surface aperture, effectively prevent vibration noise, reduces navigation
Resistance；
It avoids hull surface aperture bring pocket noise, prevent sealing of hole cover board from being motivated generation vibration noise by fluid；
Ship sailing resistance when not working can be effectively reduced according to putting propeller outside need of work or packing up propeller；
Device external arrangement, saves arrangement space in cabin；
Hull openings are reduced, safety is improved.
