The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1 be propeller arrangement scheme drawing provided by the invention, screw propeller provided by the invention comprises propeller hub 3 and blade mechanism 4.Described propeller hub 3 adopts rotary-disk type structures, four blade mechanisms 4 be distributed on propeller hub 3 around, described propeller hub 3 is fixedly connected on the main shaft 2, main shaft 2 is outer to be with axle sleeve 1, axle sleeve 1 one ends are fixed on the hull.During work, the propeller hub 3 of rotating disc type is installed in the hull both sides, is used to drive that ship is kept straight on or turn, and rotates and makes four blade mechanism 4 periodic duties thereby main shaft 2 drives propeller hubs 3, and then provide thrust for ship motion.
As shown in Figure 1 and Figure 2, described each blade mechanism 4 comprises automatic shutter blade 401, cam mechanism 402 and fork-shaped controller 403, governor weight 404 and shift fork device 405.Each blade mechanism 4 has two symmetrical flat blades 401, as shown in Figure 2 be the constitution diagram that two blades 401 launch fully, two blades 401 all are fixed on propeller hub 3 disk radial direction, connect by turning joint between two blades 401 in each blade mechanism 4, blade 401 can launch on perpendicular to the ship motion direction or close up, spread is 0~180 degree, is launched the expansion maximum angle of the locking plate 407 restriction blades 401 at the back side, back by blade 401.As Fig. 2, be provided with slideway 406 at blade 401 installation directions, dress can be along its governor weight that is free to slide 404 in the slideway 406.For preventing that governor weight 404 from launching the back at blade 401 and becoming flexible, at slideway 406 the most inboard (near blade 401 root positions) fork-shaped controller 403 has been installed, be hinged on propeller hub 3 disks.Cam mechanism 402 and shift fork device 405 all are fixed on the axle sleeve 1, and cam mechanism 402 is installed in blade 401 and closes up (closing up fully) position, and shift fork device 405 free end blades 401 half deployed condition places are used to control the blade 401 of half folded-out position.
As Fig. 1, there are four mode of operations in four blade mechanisms 4 of screw propeller when work, and be respectively state A (0 °): two blades 401 close up fully; State B (90 °): two blades 401 half launch; State C (180 °): two blades 401 launch fully; State D (270 °): two blades 401 narrow.In the screw propeller working process, the rotation of propeller hub 3 drive blade mechanism 4 periodically finish blade half launch from being brought together into fully, again to the process of launching fully and narrowing, close up fully once more.When needs blade 401 by complete deployed condition C when closing up state A fully, two blades 401 are rotated into the state D that narrows because hinge type connects under the drag effect of water, reduce water resistance; When needs blade 401 when closing up state A fully to complete deployed condition C, blade 401 will be through more than half deployed condition B under the combined action of the centnifugal force of governor weight 404 and blade 401 left side shift fork devices 405, continue to launch fully to be state C after the rotation, reach maximum propulsive force.
When 401 strokes to 0 °~90 ° of blades, between two positions of state A as shown in Figure 1 and state B, two blades 401 overcome at himself gravity under the effect of water resistance slowly to be opened, and progressively carries out the transition to half deployed condition B by closing up state A fully; When blade is drawn to 90 °~180 °, two blades 401 outwards launch at himself gravity, governor weight 404 is subjected to centrifugal action and is rolled to blade 401 directions by propeller hub 3 roots, after blade 401 touches shift fork device 405, shift fork device 405 is given 401 1 initial open effects of blade, thereby make blade 401 launch (state C) automatically fully, at this moment, because the maximum angle that 407 pairs of left and right sides blades of locking plate 401 launch is controlled at 180 °, thereby the planes of being launched automatically to form by governor weight 404 and fork-shaped controller 403 control blades 401 are perpendicular to working direction (state C), this moment, governor weight 404 was positioned at the blade expansion plane of blade 401 roots, it is the distal-most end of slideway 406, thereby blade 401 maximum areas ground is contacted with water, produce maximum propulsive force; When 401 strokes to 180 °~270 ° of blades, blade 401 is progressively carried out the transition to by complete deployed condition C under himself gravity and water resistance combined action and narrows state D; When blade 401 strokes to 270 °~360 ° (0 °), cam mechanism 402 is pulled to slideway 406 roots by driving fork-shaped controller 403 with governor weight 404, promptly away from blade 401 directions, blade 401 will progressively be carried out the transition to by the state D that narrows under the antagonistic force of the resistance of water and fork-shaped controller 403 and close up state A fully, at this moment, the blade plane is parallel with the ship running direction, the resistance of water in the time of can reducing ship running, thus improved propulsion coefficient.So far, this has finished an orbit period to blade 401.
Carry out the transition to the complete deployed condition C process from closing up state A fully at blade 401, in order to guarantee the reliable expansion of blade 401, a shift fork device 405 has been installed on axle sleeve 1, shift fork device 405 free ends are positioned at half deployed condition B position, as Fig. 3, when blade 401 runs to when contacting with shift fork device 405, the blade 401 that holds together that narrows will be forced blade 401 is deployed into certain angle under the tension force effect of shift fork device 405, so just the expansion fully for blade 401 provides precondition, then governor weight 404 will move to the surface of blade 401 under action of centrifugal force, with locking plate 407 combineds action blade 401 be launched fully.
Described cam mechanism 402 as shown in Figure 4, in order to reduce the resistance of water, when blade 401 ran to the position that is unfavorable for ship's navigation, blade 401 must close up fully could realize that blade 401 and water engaging surface are long-pending minimum, thus negative resistance power minimum.In order to guarantee accurately closing up of blade 401, side near propeller hub 3 on axle sleeve 1 has designed a cover cam mechanism 402, when blade 401 runs to these cam mechanism 402 positions, fork-shaped controller 403 will move to governor weight 404 root of propeller hub 3 rotating disk circumference from the position that promotes blade 401 to launch under the effect of cam mechanism 402, thereby can realize smoothly closing up fully of blade 401, therefore, cam mechanism 402 mainly plays the effect that guarantees that blade 401 closes up fully.
Quadruplet or the similar propeller arrangement provided by the invention of six covers can be installed on common ship 5 simultaneously, as shown in Figure 4, when running into wind and waves and torrent in the process of moving, the good stability of ship 5, propulsive effort is big, and the war outlet capacity is strong; When turning and changing course, maneuvering performance is good, highly sensitive, by reconciling the direction that never just can regulate ship 5 with the rotating speed of screw propeller.
