Abstract
The utility model provides a bionical duck web oar, includes, dead lever, preceding sliding sleeve, back sliding sleeve, a plurality of oar piece, a plurality of connecting rod to and the fixing base, wherein, the one end of dead lever is installed on the fixing base, preceding sliding sleeve back sliding sleeve cup joints respectively slide on the dead lever, a plurality of oar pieces respectively with backward slip cover hub connection, and pass through a plurality of connecting rods with advancing slip set of hub connection. The utility model discloses a bionical duck web oar adopts impeing of bi -directional motion, even pasture and water are hung by the oar bone when impeing, also can break away from the winding when withdrawing, and uses the supplementary paddle of double -deck sliding sleeve to open, and certain angle of can deflecting when foling makes the blade overlap each other, reduces the water resistance.
Description
Technical field
The utility model relates to a kind of propelling unit, particularly relates to a kind of oar of propelling unit.
Background technology
In prior art, the propelling unit of boats and ships generally adopts screw propeller mode, screw propeller is made up of oar drum and screw blade, screw propeller is connected with the output shaft of engine through transmission shaft, transmission shaft is through bearing, bearing seat and sealing arrangement and be connected on hull, the corresponding screw propeller junction of hull is provided with ship stern pipe or beauty's frame, transmission shaft carrying screws rotates with the navigation driving boats and ships, during navigation, screw propeller oar drum and the groove between ship stern pipe or beauty's frame and screw propeller oar drum are usually by the floating debris in water, fishing net, the windings such as hawser, affect the normal work of screw propeller, sometimes also can cause damaging screw propeller, boats and ships run out of steam, cause a serious accident.
Publication number is that CN203793579U discloses a kind of antiwind tandem airscrew propeller, comprise tailing axle and screw propeller, at least two screw propeller tandem are arranged on tailing axle, tailing axle run through be installed in propeller boss and screw propeller propeller hub in, propeller boss is fixedly supported on the afterbody of hull by bracing frame, be located in propeller boss tail shaft rotatable, tailing axle is fixed in propeller hub, multi-disc rotates pitch cutting and is fixed on the fore end outer circumference face of propeller hub, the outer circumference surface of propeller boss near the one end rotating pitch cutting is provided with protective cover, multi-disc is fixed pitch cutting and is fixed in protective cover periphery, fixing pitch cutting is located at protective cover one end near propeller hub, the leaf of propeller blade does not slightly exceed hull bottom baseline.This utility model utilizes the rotational automatic of screw propeller to cut twister, but there is drawback in this method, softer pasture and water can only be cut when high speed rotating, and it is larger to engine pressure, in slow rotation or when running into the hard twister such as fishing net, hawser, produce little effect, still can cause damaging screw propeller, boats and ships and run out of steam, cause a serious accident.
Summary of the invention
In order to solve the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bionical die Schwimmhaut oar, and before and after adopting, the propulsion mode of bidirectional-movement, can effectively prevent by windings such as the floating debris in water, fishing net, hawsers.
To achieve these goals, bionical die Schwimmhaut oar of the present utility model, comprises, fixed link (having slide rail vertically), front sliding sleeve, rear sliding sleeve, multiple blade, multiple connecting rod, and permanent seat, wherein,
One end of described fixed link is arranged on described permanent seat; Described front sliding sleeve, described rear sliding sleeve to be socketed in respectively on described fixed link and to slide;
Described multiple blade is connected with described rear sliding sleeve axle respectively, and is connected with described advancing slip sleeve by described multiple connecting rod.
Wherein, described fixed link, its external peripheral surface is provided with slide rail vertically.
When the connecting rod connected with motor promotes front shaft sleeve, under the effect of rear axle housing friction force and water resistance, blade is opened and is pushed into fixed link end backward; Now connecting rod is pulled back front shaft sleeve, and under the effect of rear axle housing friction force and water resistance, blade closes up and regains homeposition
Bionical die Schwimmhaut oar of the present utility model adopts the carrying out of bidirectional-movement to advance, even if oar bone tangles pasture and water when advancing, also can break away from winding when withdrawing, and use double-deck sliding sleeve to assist blade to open, can certain angle be deflected when closing up, make blade overlapped, reduce water resistance.
Other features and advantages of the utility model will be set forth in the following description.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification sheets, and is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is according to perspective view during bionical die Schwimmhaut paddle blade expansion of the present utility model;
Fig. 2 is according to perspective view during bionical die Schwimmhaut paddle blade contraction of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Fig. 1 is according to perspective view during bionical die Schwimmhaut paddle blade expansion of the present utility model, Fig. 2 is according to perspective view during bionical die Schwimmhaut paddle blade contraction of the present utility model, as illustrated in fig. 1 and 2, bionical die Schwimmhaut oar of the present utility model, comprise, fixed link 1, rear sliding sleeve 2, multiple connecting rod 3, multiple blade 4, front sliding sleeve 5, and permanent seat 6.Wherein:
Fixed link 1, is provided with slide rail 7 vertically at its external peripheral surface, and one end of fixed link 1 is arranged on permanent seat 6;
Front sliding sleeve 2, rear sliding sleeve 5 are enclosed within fixed link 1 respectively, along slide rail 7 slide anteroposterior on fixed link 1;
Each blade 4, its one end is connected with rear sliding sleeve 5 axle, and centre portion is connected with front sliding sleeve 2 axle by connecting rod 3.
Bionical die Schwimmhaut oar of the present utility model, comprises the oar face of multiple hard, forms a circle, very more stable and stronger when opening; When closing up, multiple oar face rotates to an angle to overlap the to each other simultaneously and is combined, and makes every a slice all parallel with water (flow) direction, very ideally decreases resistance.The front sliding sleeve 5 that blade 4 is housed slides on fixed link 1, and the rear sliding sleeve 2(auxiliary water resistance that another damping is slightly large opens or closes up blade) connecting rod 3 is housed connects in the middle part of blade, help blade 4 to open; The axle that blade 4 rotates is deflection slightly, and when blade 4 opens completely, the direction of all axles is level, and can deflect certain angle when closing up, and makes blade overlapped, reduces water resistance.
One of ordinary skill in the art will appreciate that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme that foregoing embodiments is recorded, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
