Abstract
The utility model relates to a folding web type ship impeller which mainly comprises a connection arm, a water diversion support, a web plate I and a web plate II. One end of the connection arm is connected with threads, and the other end of the connection arm is connected with the water diversion support. The water diversion support is a V-shaped groove structure formed by two water diversion plates and two side plates, and rotating shaft through holes are correspondingly formed in the two side plates. The web plate I is hinged with the web plate II through a rotating shaft, and two ends of the rotating shaft respectively extend out of the two rotating shaft through holes of the two side plates. Choke plugs are respectively sleeved on extending-out parts of the rotating shaft. The folding web type ship impeller is a novel structural ship impeller, provides driving force for sailing of a ship through continuous unfolding and closing of the web plates, can not generate high-speed cycle driving force due to slow action of paddling, and is small in noise and good in hidden performance compared with a screw propeller.
Description
Technical field
The utility model relates to the propulsion of ship technical field, is specifically related to a kind of folding web formula ship propeller.
Background technology
At present, the onward impulse of most of ship navigation is to rotate to produce propulsive force by screw propeller, promotes steamer and advances.The resistance of water is very large during the screw propeller motion, causes manipulation strength large, inefficiency, directly affect the route speed of ship, and can produce larger noise, when being assemblied in especially on the small-sized pleasure-boat, the tail gas that this marine propeller brings and noise emission can bring larger human discomfort to the visitor.
The utility model content
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of folding web formula ship propeller is provided, because its arm stroke is slow, does not produce cycle driving force at a high speed, and relatively noise is less for spiral propeller relatively.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that adopts is: a kind of folding web formula ship propeller, described propelling unit is mainly by connecting arm, divide the water support, paddle blade I and paddle blade II form, one end of connecting arm is provided with connecting thread, the other end of connecting arm connects a minute water support, described minute water support is two minutes water plates and two v-depression structures that side plate consists of, correspondence is provided with the rotating shaft through hole on described two side plates, paddle blade I and paddle blade II are hinged by rotating shaft, and two rotating shaft through holes of two side plates are stretched out respectively at the two ends of rotating shaft, and the sponson at rotating shaft two ends is arranged with chock plug.
Be 140～160 ° of angles between described two minutes water plates.
Stop block all has been sticked on the opposite face of described paddle blade I and paddle blade II.
Beneficial effect
Folding web formula ship propeller of the present utility model is a kind of ship propeller of brand new, utilize continuous expansion and the closure of paddle blade, for the navigation of boats and ships provides propelling thrust, because its arm stroke is slow, can not produce cycle driving force at a high speed, and relatively noise is less for spiral propeller relatively, and disguise is also better.

Mark among the figure: 1, connecting arm, 2, minute water support, 3, the paddle blade I, 4, the paddle blade II, 5, minute water plate, 6, side plate, 7, the rotating shaft through hole, 8, rotating shaft, 9, chock plug, 10, stop block.
The specific embodiment
As shown in the figure: a kind of folding web formula ship propeller, mainly formed by connecting arm 1, minute water support 2, paddle blade I 3 and paddle blade II 4, wherein an end of connecting arm 1 is provided with connecting thread, and the other end of connecting arm 1 connects a minute water support 2.
Described minute water support 2 wherein was 140～160 ° of angles in two minutes for to consist of the v-depression structure by two minutes water plates 5 and two side plates 6 between the water plate 5, correspondence is provided with rotating shaft through hole 7 on described two side plates 6.
Paddle blade I 3 and paddle blade II 4 to pass through rotating shaft 8 hinged, similar to traditional hinge structure, paddle blade I 3 and paddle blade II 4 all can be rotated along rotating shaft 8, wherein 4 one sides of paddle blade I 3 and paddle blade II are the concavo-convex groove structure that cooperatively interacts, paddle blade I 3 and paddle blade II 4 can be entrenched togather with the side of concavo-convex groove structure, and it is hinged with paddle blade I 3 and paddle blade II 4 to pass phase embedding part by rotating shaft 8, the rotating shaft through hole 7 of two side plates 6 is stretched out respectively at the two ends of described rotating shaft 8, and is arranged with chock plug 9 at sponson.Be provided with stop block 10 on the opposite face of described paddle blade I 3 and paddle blade II 4, stop block 10 arranges near rotating shaft 8.
Two paddle blade I 3 and paddle blade II 48 are rotated around the shaft, outwards rotate when two paddle blades until run into two minute water plates 5 of minute water support 2, this moment two paddle blades owing to dividing a water plate 5 to stop and can't being rotated further, two paddle blades are deployed condition.Inwardly rotation is until two stop blocks 10 contact when two paddle blades, and this moment, two paddle blades can't be rotated further, and two paddle blades are in closure state.
Moving system peculiar to vessel comprises main drive spindle and is symmetricly set on a plurality of pushers of main drive spindle both sides, pusher is connected with main drive spindle by connecting arm 1, and the groove of angle of rake minute water support 2 is towards unanimously, all towards stern one end, divide the 2 vertical direction settings of water support, paddle blade I 3 and paddle blade II 4 are in the left and right sides of rotating shaft 8.Main drive spindle moves reciprocatingly under the driving of motor and transmission device, driving simultaneously all propelling units moves reciprocatingly in water, when propelling unit travels forward, because angle of rake two paddle blades meeting of the drag effect of water auto-closing, angle of rake minute water support 2 also can play the effect of shunting so that propelling unit when travelling forward resistance very little.And when propelling unit moves backward, because two paddle blades of effect of current open automatically, becoming a quant, the antagonistic force when utilizing to pusher water promotes hull and advances.In crank motion, two paddle blades constantly launch, closedly realize advancing of ship.
Folding web formula ship propeller of the present utility model because its arm stroke is slow, does not produce cycle driving force at a high speed, and spiral propeller comparison noise is less relatively, and disguise is also better.
