Abstract
The invention discloses an anti-compression type propeller which comprises first propeller blades, second propeller blades and a propeller seat. The first propeller blades and the second propeller blades are both fixedly installed on the outer side edge of the propeller seat, the cross sections where the first propeller blades are located and the cross sections where the second propeller blades are located are distributed front and back in the length direction of the propeller seat, and each second propeller blade is located between every two adjacent first propeller blades. In this way, the unloading capacity of the propeller blades can be improved, therefore, the anti-compression performance of the propeller is significantly improved, the service life is prolonged, and meanwhile the propulsive efficiency is high.
Description
Technical field
The present invention designs a kind of marine equipment, particularly relates to a kind of Anti-pressure Anti-pressure propeller blade.
Background technology
Screw propeller depends on blade to rotate in air or water, be the device of propulsive force by turn of engine power conversion, two or more leaf can be had to be connected with hub, the one side backward of leaf is helical surface or a kind of ship propeller being similar to helical surface, and blade plan form in prior art in screw propeller is various, but stereotyped, be all adopt, at same section, blade is installed, the major defect of this screw propeller is: off loading capacity is torn open, and compressive property is poor.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of Anti-pressure screw propeller, can promote the off loading capacity of propeller blade, thus significantly improves the compressive property of screw propeller, increases the service life, and propulsion coefficient is high simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of Anti-pressure screw propeller, comprise: the first propeller blade, second propeller blade and screw propeller seat, described first propeller blade and described second propeller blade are all fixedly mounted on the outer side edges edge of described screw propeller seat, the cross-sectional plane at described first propeller blade place cross-sectional plane and described second propeller blade place is that front and back distribute along the length direction of described screw propeller seat, and each described second propeller blade is all positioned at the centre of the first propeller blade described in adjacent two.
In a preferred embodiment of the present invention, described first propeller blade is identical with the shape of described second propeller blade.
In a preferred embodiment of the present invention, the length of described first propeller blade is greater than the length of described second propeller blade.
In a preferred embodiment of the present invention, described first propeller blade is identical with the material of described second propeller blade.
The invention has the beneficial effects as follows: the present invention can be installed with two kinds of propeller blades on screw propeller seat, and these two kinds of propeller blades are in different cross section, the off loading capacity of propeller blade can be promoted, thus significantly improve the compressive property of screw propeller, increase the service life, propulsion coefficient is high simultaneously.
Accompanying drawing explanation
Fig. 1 is a kind of Anti-pressure screw propeller of the present invention front elevation in a preferred embodiment;
Fig. 2 is a kind of Anti-pressure screw propeller of the present invention lateral plan in a preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, the first screw propeller, the 2, second screw propeller, and 3, screw propeller seat.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention is:
A kind of Anti-pressure screw propeller, comprise: the first propeller blade 1, second propeller blade 2 and screw propeller seat 3, described first propeller blade 1 and described second propeller blade 2 are all fixedly mounted on the outer side edges edge of described screw propeller seat 3, the cross-sectional plane at described first propeller blade 1 place cross-sectional plane and described second propeller blade 2 place is that front and back distribute along the length direction of described screw propeller seat 3, and each described second propeller blade 2 is all positioned at the centre of the first propeller blade 1 described in adjacent two.
In the present embodiment, described first propeller blade is identical with the shape of described second propeller blade; The length of described first propeller blade is greater than the length of described second propeller blade; Described first propeller blade is identical with the material of described second propeller blade.
Present invention is disclosed a kind of Anti-pressure screw propeller, its cardinal principle is: when screw propeller seat 3 starts to rotate, first propeller blade 1 and the second propeller blade 2 also rotate simultaneously, because the first propeller blade 1 and the second propeller blade 2 are in different cross section, the pressure that first screw propeller 1 blade is produced can eliminate the pressure that current cause to the second propeller blade 2, thus improve the unloading force of screw propeller, improve compressive property, the pressure that the pressure that second propeller blade 2 produces simultaneously can cause with the first propeller blade 1 is superimposed, add propulsion coefficient.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
