The technical scheme of the utility model is:
Surperficial oar propulsive unit peculiar to vessel; Mainly by forming: adjust oil cylinder, steering oil cylinder, central siphon, surperficial oar, axle system, joint ball, universal coupling, stern tube shaft butt flange, deflecting plate, hydraulic pressure unit, input shaft up and down, it is characterized in that: adjust oil cylinder up and down, the steering oil cylinder links to each other with hydraulic pressure unit respectively, adjust oil cylinder up and down, the steering oil cylinder links to each other with central siphon respectively with lower component; Axle system is installed in the central siphon; One end of axle system is captiveed joint with surperficial oar, and the gear case on the ship links to each other with the stern tube shaft butt flange, and the stern tube shaft butt flange links to each other with input shaft; Input shaft links to each other with the other end of axle system; On the other end of axle system joint ball and universal coupling are installed successively, and universal coupling is the arbitrarily angled rotation of basic point with the centre of sphere with joint ball, deflecting plate is installed in bottom the central siphon.Wherein gear case is independent equipment, is not included in the utility model device;
Can be under the described effect of adjusting hydraulic lock and the change-over valve of oil cylinder through hydraulic pressure unit up and down arbitrarily angled fixing voluntarily and move up and down, and the described oil cylinder of adjusting up and down moves up and down with the horizontal plane angle scope and is no more than 15 degree.
Can be under the effect of hydraulic lock and the change-over valve of described steering oil cylinder through hydraulic pressure unit in the fixing voluntarily and sway of angle arbitrarily, and described steering oil cylinder left rotation and right rotation is no more than 40 with the vertical surface angular range and spends.
The utility model is exactly the screw propeller that waterline just in time passes its propeller hub in the ship navigation.The oar axle is passed the stern transom plate of hull, make the current that flow out from the stern transom plate below directly act on screw propeller, the rotating speed of screw propeller is improved, thereby reach the purpose that improves propeller efficiency.In surperficial oar propulsive unit propulsion system, screw propeller oar axle is through a pair of cardan shaft drive that is positioned at oily close ball-and-socket the inside, and main shaft rotates with control screw propeller submergence degree at above-below direction.Important characteristic is exactly that half cycle is all arranged when fortune circles is in the water outside to each blade during running.
The utility model can make full use of domestic material, advantage that the tooling cost expense is low, substitutes import, satisfies the needs in domestic military, civilian market.
Description of drawings
Fig. 1 is the Facad structure scheme drawing of the utility model.
Fig. 2 is Fig. 1 opposite side structural representation.
The specific embodiment
In conjunction with the accompanying drawings the utility model is further described.
Like Fig. 1, shown in Figure 2; The utility model is mainly by forming with lower component: adjust oil cylinder 1, steering oil cylinder 2, central siphon 3, surperficial oar 4, axle up and down and be 5, joint ball 6, universal coupling 7, stern tube shaft butt flange 8, deflecting plate 9, hydraulic pressure unit, input shaft 10; It is characterized in that: adjust oil cylinder 1 up and down, steering oil cylinder 2 links to each other with hydraulic pressure unit respectively; Adjust oil cylinder 1 up and down, steering oil cylinder 2 links to each other with central siphon 3 respectively, axle is 5 to be installed in the central siphon 3, axle is that an end of 5 is captiveed joint with surperficial oar 4 through spline; Gear case on the ship links to each other with stern tube shaft butt flange 8; Stern tube shaft butt flange 8 links to each other with input shaft 10 through universal coupling 7, and wherein gear case is independent equipment, is not included in the utility model device; Input shaft 10 and axle are that 5 the other end links to each other, and axle is on 5 the other end joint ball 6 and universal coupling 7 to be installed successively, and universal coupling 7 and joint ball 6 be the arbitrarily angled rotation of basic point with the centre of sphere, and deflecting plate 9 is installed in central siphon 3 bottoms.Lean on hydraulic pressure unit to rotate turnover oil when realizing that oil cylinder is flexible up and down when adjusting oil cylinder 1, steering oil cylinder 2 up and down; Driving central siphon 3 swings up and down; So surperficial oar 4 also swings up and down with central siphon 3, gear case drives and drives surperficial oar 4 rotations when stern tube shaft butt flange 8 rotates.Can be under the described effect of adjusting hydraulic lock and the change-over valve of oil cylinder 1 through hydraulic pressure unit up and down arbitrarily angled fixing voluntarily and move up and down, and on move down angular range and be no more than 15 degree.Can be under the effect of hydraulic lock and the change-over valve of described steering oil cylinder 2 through hydraulic pressure unit in the fixing voluntarily and sway of angle arbitrarily, and the angular range of left and right sides swing angle is no more than 40 degree.
The operating principle of the utility model
1. navigate by water the knee-action of center shafting
A. the upwards action of axle system
Adjust the effect of oil cylinder 1 through change-over valve up and down and make himself, cause coupled central siphon 3 upwards to promote to being retracted into.Because central siphon 3 and axle are 5 to link to each other, make that axle is 5 also upwards liftings again.In the process that promotes, adjust oil cylinder 1 up and down through fixing voluntarily and move up and down arbitrarily angled under the effect of hydraulic lock and change-over valve, last pivot angle degree scope is no more than 7.5 degree (with horizontal plane angle).
The downward action of b, axle system
Adjust the effect of oil cylinder 1 through change-over valve up and down and make and himself extend forward, cause coupled central siphon 3 to squint downwards,, make spool to be 5 also to squint downwards again because surperficial oar 4 and axle are 5 for captiveing joint.In the out-of-position process, adjusting up and down under the effect of hydraulic lock and the change-over valve of oil cylinder 1 through hydraulic pressure unit can be arbitrarily angled fixing voluntarily and move up and down.The pivot angle scope that moves down is no more than 7.5 degree (with horizontal plane angle).
Steering action in the navigation
Rudder left-handed
Because steering oil cylinder 2 is connected with central siphon 3, steering oil cylinder 2 to being retracted into, makes central siphon 3 under its effect, follow anti-clockwise rotation under the effect of change-over valve.In the process of rotation, the effect of hydraulic lock and the change-over valve of steering oil cylinder 2 through hydraulic pressure unit is down can be in angle arbitrarily fixing voluntarily and move up and down, and the swing angle degree is no more than 20 and spends (with the vertical surface angle) up and down.
The dextrorotation of rudder
Steering oil cylinder 2 extends forward under the effect of change-over valve; Make central siphon 3 under its effect, follow right-hand revolution; In the process of rotation; Can be under the effect of hydraulic lock and the change-over valve of steering oil cylinder 2 through hydraulic pressure unit in arbitrarily angled fixing voluntarily and left rotation and right rotation, about revolve maximum angle 20 degree (with the vertical surface angle).
