Abstract
The utility model discloses a direction-variable screw propeller, which comprises a propeller hub and paddles uniformly distributed on the propeller hub and is characterized in that long shafts are fixedly and uniformly distributed on the outer edge of the propeller hub, the blades are respectively sleeved on the corresponding long shafts, a positioning sleeve is sleeved on the propeller hub through positioning clamping jaws uniformly distributed on the positioning sleeve, the positioning clamping jaws and the paddles are identical in number, each positioning clamping jaw is arranged between every two adjacent paddles, and the positioning sleeve can push the paddles to rotate through the positioning clamping jaws during rotation so as to change the directions of the paddles. The utility model has the advantages that: because the positioning sleeve can push the paddles to rotate through the positioning clamping jaws during rotation so as to change the directions of the paddles, the paddles of the direction-variable screw propeller can be changed according to needs so as to ensure that the paddles can generate the maximum propelling force; and the paddles occupy a small space after rotating, so that the direction-variable screw propeller is convenient to carry. The direction-variable screw propeller can supply power or convert energy for various devices capable of overcoming difficult water buoyancy.
Description
Technical field
The utility model is particularly related to a kind of direction-changing type screw propeller.
Background technology
Existing screw propeller is to be made up of propeller hub and at least two blades that are located on the propeller hub.Its blade and propeller hub are affixed, so blade can not change of direction, and it is big to take up room, and is not easy to carry.
Summary of the invention
The technical matters that the utility model will solve is will provide a kind of can change the blade angle as required, thereby can produce maximum propulsive force, portable direction-changing type screw propeller.
The direction-changing type screw propeller that the utility model relates to comprises propeller hub and is distributed on the blade on the propeller hub; Its special character is: be uniformly distributed with in the propeller hub outer rim and be fixed with major axis; Described blade is enclosed within respectively on the cooresponding major axis; On propeller hub, be arranged with locating bush; Locating bush is enclosed within on the propeller hub through the location claw that is uniformly distributed with above that, described location claw and blade quantity quite and each location claw lay respectively between adjacent two blades, change the blade direction thereby can promote the blade rotation through the location claw during rotation of described locating bush.
Above-mentioned direction-changing type screw propeller is provided with clip at the front end sleeve of locating bush, guarantees that to realize changing the relative position of locating bush and propeller hub fixes after the blade direction.
The utility model has the advantages that: thereby because locating bush when rotation can promote the blade rotation through the location claw and change the blade direction, so this direction-changing type screw propeller can change the blade angle as required, thereby guarantee that blade produces maximum propulsive force; It is little to take up room after the blade rotation, is easy to carry; This direction-changing type screw propeller can overcome the difficult devices of buoyancy in the water with various, combines like the vehicle or aerogenerator etc., for it provides power or transformation of energy.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the postrotational structural representation of blade among Fig. 1.
Among the figure: propeller hub 1, binding bolt 2, locating bush 3, location claw 301, major axis 4, nut 5, blade 6, clip 7.
The specific embodiment
As shown in the figure; The direction-changing type screw propeller that the utility model relates to comprises propeller hub 1; Be uniformly distributed with through being threaded in propeller hub 1 outer rim and be fixed with major axis 4; On each major axis 4, be arranged with blade 6 respectively, blade 6 is spacing through the nut 5 that is located at major axis 4 outer ends, and present embodiment major axis 4 is an example with four respectively with blade 6.On propeller hub 1, be arranged with locating bush 3; Locating bush 3 is enclosed within on the propeller hub 1 through the location claw 301 that is uniformly distributed with above that; Described location claw 301 is " fourth " font and suitable with blade 6 quantity; Each location claw 301 lays respectively between adjacent two blades 6, changes blades 6 directions thereby can promote blade 6 rotations through location claw 301 during described locating bush 3 rotation.Front end sleeve at locating bush 3 is provided with clip 7; Clip 7 is connected through screw with one of them location claw 301; On clip 7, be provided with binding bolt 2; Can location claw 301 be fastened on the propeller hub 1 through clip 7, fix to guarantee the relative position of locating bush 3 and propeller hub 1 after realization change blade 6 directions.
During use, unclamp binding bolt 2 and positioning of rotating cover 3 on the clip 7,, make the big face and propeller hub 1 parallel axes of blade 6, again clip 7 lockings are got final product, can this screw propeller be installed on the marine communication means at this moment through locating claw 301 promotions and leaning on blade 6.Unclamp clip 7 and positioning of rotating cover 3, promote and block big face and propeller hub 1 axis normal that blade 6 makes blade 6 through location claw 301, blade 6 takes up room for a short time at this moment, is easy to carry.
Claims (2)
1. direction-changing type screw propeller; Comprise propeller hub and be distributed on the blade on the propeller hub; It is characterized in that: be uniformly distributed with in the propeller hub outer rim and be fixed with major axis; Described blade is enclosed within respectively on the cooresponding major axis, on propeller hub, is arranged with locating bush, and locating bush is enclosed within on the propeller hub through the location claw that is uniformly distributed with above that; Described location claw and blade quantity quite and each location claw lay respectively between adjacent two blades, change the blade direction thereby can promote the blade rotation through the location claw during rotation of described locating bush.
2. direction-changing type screw propeller according to claim 1 is characterized in that: the front end sleeve at locating bush is provided with clip.
