Abstract

A floating push-pull propulsion for ship features structurally that the power source, speed varying mechanism, coaxial crank-shaft connection mechanism, and multiple groups of crank, crank connecting rod, guide slide block, push-pull rod, hinge and push-pull plate pair are sequentially linked. Under the drive of push-pull rod, two pus-pull plates in a pair are opened and closed alternatively to increase their push force and decrease their reverse resistance. Multiple pairs are combined can generate great drive force.

Description

Floating open close push pull type propellor for ship

[technical field]

The present invention is the ship propeller technical field.It specifically is exactly floating open close push pull type propellor for ship.

[technical background]

As everyone knows, modern ship propeller all be a screw propeller, relatively Yi Qian manual strip shake that can be with regard to a world of difference.Is but whether its efficient the limit? answer is negated.Because screw propeller is with the form imput power that rotates, rely on the front and back of the straight line pitch of screw propeller to change to realize to the thrust of ship.Obviously, its efficient is not high.So, is there what approach to improve the input efficiency of its power? this device addresses this problem.

[summary of the invention]

The present invention is a kind of later-model propelling unit that provides for all steamers specially.Its principle is: two purpose mades are easy to the end that the different thickness of hydrogymnastic fleetline have the push-and-pull clamping plate of certain buoyancy are fixed in same hinge, the other end is a free end, rely on the different buoyancy that they had, pull bar one at hinged end pushes away in the process of drawing the thrust that one one on these two clamping plate close realization to ship.Draw one one to be combined in and to reach within one second for several times because this pushes away one, thereby just can greatly improve the propulsive force and the ship's speed of ship.

Among the figure: propulsion source 1, speed-changing mechanism 2, concentric crank connecting shaft mechanism 3, crank connecting link 4, guide runner 5, pull bar 6, steamer body 7, floating opening and closing push-and-pull clamping plate 8 (wherein I is last thick clamping plate, and II is following thin clamping plate), rudder for ship 9, clamping plate bearing iron hinge 10, clamping plate buoyancy compartment 11, buoyancy compartment reinforced rib dividing plate 12, water mouth 13, pull bar clamping plate thrust bearing 14, crank 15, the long rope of limit floating fixed (chain) 16.

A among Fig. 1 Fig. 2, B, C, D and A ', B ', C ', D ' for the rudder be both sides, axle center alphabet sequence symmetric offset spread corresponding to the same floating opening and closing push-and-pull clamping plate group (to) and they in concentric crank connecting shaft mechanism 3, be the center of circle symmetry position of uniform (this illustration shows middle a=90 ') with the crank centre of gration.L, L1 are that floating opening and closing push-and-pull clamping plate 8 are when end position and the distance of rudder and hull.

Among Fig. 4, floating opening and closing push-and-pull clamping plate 8 must guarantee when opening below the absolute water surface and with hull structure when contradictory, the up and down difference H of pull bar 6 inside and outside hull.

[embodiment]

Among Fig. 1 Fig. 2 Fig. 3, propulsion source 1, speed-changing mechanism 2 drive concentric crank connecting shaft mechanism 3, many set of bell cranks 15, and crank connecting link 4, guide runner 5, pull bar 6, bearing iron hinge 10, push-and-pull clamping plate 8 are connected with concentric crank connecting shaft mechanism 3.When propulsion source 1 outputting power, the speed retaining that requires conversion speed-changing mechanism 2 according to ship's speed, concentric crank connecting shaft mechanism 3 will be with corresponding speed rotation, and by crank, straight-line motion before and after crank connecting link 4 is done by pull bar 6 push-and-pull clamping plate hinges 10 and then push-and-pull floating opening and closing push-and-pull clamping plate 8 with the guiding of guide runner 5.In this course, because of the resistance of water makes floating opening and closing push-and-pull clamping plate 8 open work done under pull bar 6 promotes, close under the pulling.

From Fig. 5 Fig. 6 Fig. 7 Fig. 8 as can be known: when pull bar 6 promotes, because design has water mouth 13, inclination angle r (r is for dividing the angle sum up and down equally) and the big buoyancy of last thick clamping plate I and the faint buoyancy of following thin clamping plate II, and open up and down immediately, make the bearing surface of clamping plate 8 increase, under the support and thrust of pull bar clamping plate thrust bearing 14, and then promotion hull 7 moves rapidly towards opposite direction.Also be since the resistance of water make floating opening and closing push-and-pull clamping plate 8 at pull bar 6 to pulling back when moving, under the buoyancy of thin clamping plate II down rapidly the level of floating into planar be depressed with being subjected to resistance on thick clamping plate I form a stressed very little stream line pattern sheet body.Because many set of bell cranks 15 are arranged, crank connecting link 4, guide runner 5, pull bar 6, hinge 10, the push-and-pull clamping plate 8 [A among Fig. 1 Fig. 2 (A ') that is connected with concentric crank connecting shaft mechanism 3, B (B '), C (C '), D (D ') for rudder 9 be axle center bilateral symmetry and alphabet sequence arrangement corresponding to the same floating opening and closing push-and-pull clamping plate group (to) and they in a side concentric crank connecting shaft mechanism 3 of rudder for ship 9, be the position of the center of circle uniform (a=90 ' in this illustration 1) with the crank centre of gration], therefore, at any one time, have 2 groups or 4 at least forming two is that axle center monosymmetric floating opening and closing push-and-pull clamping plate 8 (having 4 groups 2 pairs in this illustration 3) are for opening the thrust work done with rudder 9.Because the rotating speed of concentric crank connecting shaft mechanism 3 is per minute commentaries on classics up to a hundred even thousands of, therefore, this pushes away one and draws one one to be combined within one second and can to reach certain number of times, thereby promotes hull towards opposite direction high-speed motion.

A among Fig. 1 Fig. 2 (A '), B (B '), C (C '), D (D ') are for the rudder being the 8 groups 4 pairs floating opening and closing push-and-pull clamping plate 8 (group number must at least more than 6 groups 3 pairs) of the corresponding symmetric offset spread of both sides, axle center alphabet sequence, with the crank centre of gration is that the center of circle is symmetrically distributed, adjacent intercrank included angle equals 90 degree (this angle is at least smaller or equal to 120 degree a＜=120 '), so (removing unprovoked rudder for ship 9 turns to hull 7) hull can the held stationary straight-line motion.

Pull bar clamping plate thrust bearing 14 must be firm and when pull bar 6 pullings in Fig. 1 Fig. 3, its shape towards moving direction one side must be water resistance is minimum flat pair of pike pole of the point of stream line pattern up and down, and it should be complementary consistent with the shape of stream line pattern one side of clamping plate 8 and floating opening and closing push-and-pull clamping plate 8 must maintain a certain distance (L, L1＞0) with rudder for ship 9 and hull 7 when being pushed into end position in the shape of clamping plate 8 one sides.

Fig. 4 is with hull 7 structures when contradictory, and the inside and outside pull bar 6 of hull can be provided with that difference must be more than or equal to zero (H＞=0) up and down, and floating opening and closing push-and-pull clamping plate 8 must guarantee when opening that the upper end of push-and-pull clamping plate each on is all definitely below the water surface.

Among Fig. 6, be connected below the following thin clamping plate II in the push-and-pull clamping plate 8 the long rope of limit floating fixed (chain) the 16th with pull bar clamping plate thrust bearing 14 lower ends, make down thin clamping plate II when come-up and on the contact surface of thick clamping plate I be limited to horizontal surface or below the horizontal surface, and, when reaching this purpose, must make the long rope of this limit floating fixed (chain) for the shortest.
