Abstract
The invention discloses a kind of marine propeller, the propulsive mechanism promoted including realizing propeller rotation, the telescoping mechanism for driving propeller to stretch up and down, drive the slew gear of propeller full circle swinging and underwater gear-box, cylinder and retracting cylinder axis connection, revolving drum axle is socketed with retracting cylinder axle, revolving drum axle is connected with underwater gear-box upper end, worm couple one end connects slewing motor, the other end connects back to rotating drum shaft, revolving drum axle is connected with underwater gear-box upper end, propulsion motor is coupled by clutch with splined shaft, the splined shaft other end and hollow rotation axis connection, hollow rotary shaft is connected with underwater gear-box upper end, underwater gear-box side is provided with propeller.This marine propeller can realize the transmission of propeller and upper and lower Telescopic, change big navigating area to adapt to drinking water, 360 degree of full circle swingings of propeller screw oar are realized using cylinder driving, make the steering efficiency high of propeller, simple in construction, easy to operate.
Description
Technical field
The present invention relates to a kind of propeller, particularly a kind of marine propeller.
Background technology
The drive device of spot ship mainly includes propeller and rudder plate two parts, when propeller rotates forward promote ship to
Preceding traveling, and rudder plate is then used for controlling the travel direction of ship.Existing marine propeller can not stretch up and down, it is impossible to effectively suitable
Complicated landform is answered, changing big navigating area for drinking water can not be applicable.When vessel draft relatively depth and following current, propeller sinks to water
In, because the underwater flow velocity of the velocity ratio of the current water surface is big, the thrust that propeller obtains will reduce, and make main frame " underloading ".Have
A little propellers realize the upper and lower flexible of propeller using hydraulic oil cylinder driving mode, and to adapt to drinking water change, but oil cylinder is installed and dimension
It is high to protect cost, hydraulic oil also has the problem of polluted river water, do not agree with today's society to green requirement.
When ship needs to retreat, it is necessary to allow propeller to stop the rotation first, then inverting again could allow ship to retreat, the step
Suddenly the long period is needed, ship may proceed to the segment distance that moves forward due to effect of inertia in this time, encounter barrier
Deng danger in emergency circumstances, ship such as easily collides at the contingency.
The content of the invention
It is an object of the invention to provide a kind of environmental protection, can stretch up and down, the marine propeller of energy full circle swinging.
To achieve the above object, the present invention uses following scheme：
This marine propeller, including realize the propulsive mechanism of propeller rotation propulsion, drive flexible above and below propeller stretch
Contracting mechanism, the slew gear for driving propeller full circle swinging and underwater gear-box, it is characterised in that：The propulsive mechanism, telescopic machine
Structure, slew gear are connected with underwater gear-box upper end, and the telescoping mechanism includes cylinder, retracting cylinder axle and revolving drum axle, institute
Cylinder and retracting cylinder axis connection are stated, revolving drum axle is socketed with retracting cylinder axle, the revolving drum axle connects with underwater gear-box upper end
Connect.
The slew gear includes slewing motor and worm couple, and worm couple one end connection revolution is electronic
Machine, the other end connect back to rotating drum shaft.
Described propulsive mechanism includes propulsion motor, clutch, splined shaft and hollow rotary shaft, the propulsion motor
Coupled by clutch with splined shaft, the splined shaft other end and hollow rotation axis connection, in hollow rotary shaft and underwater gear-box
End connection.
The underwater gear-box side is provided with propeller.
Compared with prior art, remarkable advantage of the invention is：
With the characteristics of easy to use, simple in construction, the transmission of propeller and upper and lower Telescopic can be realized, to adapt to
Drinking water changes big navigating area, and 360 degree of full circle swingings of propeller screw oar are realized using cylinder driving, makes the steering efficiency of propeller
Height, and contrast and cause environmental pollution using oil cylinder, there is the advantages of green using cylinder.

Axle 7, the revolving drum axle 7 are connected with the underwater upper end of gear-box 10.
Described one end of worm couple 5 connects slewing motor 6, and the other end connects back to rotating drum shaft 7, revolving drum axle 7 and water
The upper end of lower tooth roller box 10 connects.
The propulsion motor 1 is coupled by clutch 3 with splined shaft 4, and the other end of splined shaft 4 connects with hollow rotary shaft 8
Connect, hollow rotary shaft 8 is connected with the underwater upper end of gear-box 10.
The underwater side of gear-box 10 is provided with propeller 11.
Embodiment 1
When impeller driven works, propulsion motor 1 sends power to splined shaft 4 by shaft coupling 3, and splined shaft 4 is again
The input shaft of underwater gear-box 10 is sent power to by hollow rotary shaft 8, so as to drive the rotation of propeller 11 to promote.
Embodiment 2
When propeller is flexible up and down, cylinder 2 drives the upper and lower flexible of retracting cylinder axle 9, and retracting cylinder axle 9 passes through revolving drum axle 7
The upper and lower flexible of underwater gear-box 10 is driven, now splined shaft 4 slides in hollow rotary shaft 8, completes propeller screw oar 11
It is upper and lower flexible.
