Abstract
A cohesion ring propeller comprises a rotary shaft sleeve, main paddles, an outer cohesion ring, an inner cohesion ring and auxiliary paddles, the rotary shaft sleeve is fixed with one ends of the main paddles, the other ends of the main paddles are fixed with the outer cohesion ring, and the inner cohesion ring is fixedly arranged in the middle of the main paddles. An auxiliary paddle is arranged between every two adjacent main paddles, one ends of the auxiliary paddles are fixed with the inner cohesion ring, and the other end of the auxiliary paddles are fixed with the outer cohesion ring. An inclined angle between each main paddle and the rotary shaft sleeve during fixation is 45 degrees. The shaft hole of the rotary shaft sleeve is of a regular octagon. The cohesion ring propeller has the advantages that due to the addition of the inner cohesion ring, the outer cohesion ring and the auxiliary paddles on the propeller, the amount of fluid sprayed all around during rotation of the propeller is reduced, and the flow of fluid like water, air and the like sprayed backward by the paddle rotary face is increased. In addition, due to the arrangement of the inner cohesion ring and the outer cohesion ring, vibration of the paddles is made to be reduced, energy consumption is effectively avoided, and therefore the efficiency of the propeller is improved. Due to the fact that the inner cohesion ring and the outer cohesion ring are arranged to fix the paddles, the paddles are not prone to being broken even if the paddles are too large.
Description
Technical field
The utility model relates to powered device technique field, and concrete is a kind of poly-power ring screw propeller.
Background technology
The principle of the screw propeller that generally uses all is the rotation by blade at present, and agitate water, air etc. make fluids such as water, air spray backward, promotes the main body motion by antagonistic force.The efficient of screw propeller just depend on fluids such as water that the blade plane of revolution sprays backward, air flow what, the flow of the fluid of ejection is many, efficient height then, otherwise efficient is low.If fluid to around the amount that throws away too much, then the amount of ejection is few backward, just the efficient of screw propeller has reduced.And because propeller blade has only an end and rotating shaft to fix, when screw propeller rotated, the vibrations of blade also can be taken away the part efficiency value, and these all make the efficient step-down of screw propeller.And if propeller blade is excessive, its stressed also change greatly, blade is very frangibility damage also.
The utility model content
At the problem of above-mentioned existence, the purpose of this utility model provides a kind of flow of ejecting fluid backward can increase screw propeller and rotate the time, reduces the blade vibrations, the poly-power ring screw propeller of high efficiency.
The technical solution of the utility model is: a kind of poly-power ring screw propeller, comprise rotating shaft cover, main blade, poly-power ring, binding force ring, metaplasm leaf outward, it is characterized in that: the rotating shaft cover is fixed with an end of main blade, the other end of main blade is fixed with outer poly-power ring, and the center fixed of main blade has the binding force ring; Be provided with the metaplasm leaf between every adjacent two main blades, an end and the binding force ring of metaplasm leaf are fixed, and the other end is fixed with outer poly-power ring.
The angle of inclination was 45 degree when described main blade and rotating shaft were overlapped fixedly.
The axis hole of described rotating shaft cover is octagon.
Advantage of the present utility model: by screw propeller being increased inside and outside poly-power ring, and the metaplasm leaf, reduced greatly fluid when screw propeller rotates to around the amount that throws away, the flow increase of fluids such as the water that the blade plane of revolution sprays backward, air; And owing to increased inside and outside poly-power ring, make the vibrations of blade reduce, actv. is avoided energy loss, and these have all improved the efficient of screw propeller well.And owing to be provided with inside and outside poly-power ring fixed blades, even blade is big again, also be difficult for being fractureed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is further specified.
As shown in Figure 1, rotating shaft cover 1 is fixed with an end of main blade 2, and the other end of main blade 2 is with poly-power ring 3 is fixing outward, and the center fixed of main blade 2 has binding force ring 4; Be provided with metaplasm leaf 5 between every adjacent two main blades 2, an end of metaplasm leaf 5 and binding force ring 4 are fixing, and the other end is with poly-power ring 3 is fixing outward.Wherein, main blade 2 with rotating shaft cover 1 fixedly the time angle of inclination be 45 degree, it is octagon that 1 axis hole is overlapped in rotating shaft.
