Description
Technical field
The present invention relates to propeller, more particularly to a kind of bulk freighter marine propeller.
Background technology
Bulk freighter is bulk carrier abbreviation, is to be specifically used to transport the goods for being not added with wrapping, such as coal, ore, timber, domestic animal
Poultry, cereal etc..The ship of large dry bulk cargo thing such as Bulk Transport cereal, coal, ore in sand form, salt, cement, can be referred to as dry bulk cargo
Ship, or abbreviation bulk freighter.Past few years oil price goes up always, and the propulsive efficiency of bulk freighter is more important than ever.Propeller energy
Consume is lost closely related with flow field around propeller hub and behind propeller hub.By the most structure of blade that propeller is used at this stage
Simply, it is impossible to preferably control flow field, so as to increase the use burden of propeller, the service life of propeller is constrained.
The content of the invention
The invention aims to overcome above deficiency, there is provided a kind of bulk freighter marine propeller blade.
The purpose of the present invention is achieved in that：
A kind of bulk freighter marine propeller of the present invention, wherein, including propeller center axle, propeller mounting seat and multiple
Helical blade, the propeller center axle is in cylinder, and the propeller mounting seat is by being welded to connect in the central shaft four
Week, the propeller mounting seat is in circular ring, and the propeller mounting seat is provided with multiple fixed installation plates, the fixation
Installing plate is in circumferentially disposed in propeller mounting seat, and described fixed installation plate one end is welded on the central shaft, the other end
Connect helical blade；The helical blade is arc shaped blade, and the arc shaped blade terminal position is provided with flow-guiding structure, the water conservancy diversion
Structure includes the first guide vane and the second guide vane, and first guide vane and second guide vane are curved
Structure, is set at the top of helical blade in left and right, the first guide vane length H1 and the second guide vane length H2
The ratio between be 2.8:1；The angled A of institute is 60 degree between the helical blade.
Above-mentioned a kind of bulk freighter marine propeller, wherein the helical blade quantity is 6.
Above-mentioned a kind of bulk freighter marine propeller, wherein the fixed installation plate quantity is 6.
Compared with prior art, beneficial effects of the present invention are：
Using the structure of multigroup propeller blade, six helical blades can increase substantially the propulsive efficiency of propulsion plant,
And 60 degree of angles between helical blade when being set using flow direction it is steady, be conducive to the steady of flow field around propeller hub
It is fixed.Proved by up to ten thousand scientific experimental datas, when the first guide vane length H1 and the second guide vane length H2 it
Than for 2.8:When 1, the ambient water of propeller is most stable, high degree reduce turbulent flow generation possibility, greatly improving makes
Use efficiency.Uniqueness is provided with deflector, can stablize the flow field behind propeller hub when using, can substantially improve around propeller hub and
Flow field behind propeller hub；Two flow field guide vanes are using unique arcuate structure.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the helical blade schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As illustrated, a kind of bulk freighter marine propeller of the invention, wherein, including the installation of propeller center axle 1, propeller
Seat 2 and multiple helical blades 3, the propeller center axle 1 is in cylinder, and the propeller mounting seat 2 is by being welded to connect
In the surrounding of propeller center axle 1, the propeller mounting seat 2 is in circular ring, and the propeller mounting seat 2 is provided with
Multiple fixed installation plates 21, the fixed installation plate 21 is in propeller mounting seat 2 in circumferentially disposed, the fixed installation plate 21
One end is welded on the central shaft 1, other end connection helical blade 3；The helical blade 3 is arc shaped blade, the arc
Blade end position is provided with flow-guiding structure 4, and the flow-guiding structure 4 includes the first guide vane 41 and the second guide vane 42, institute
The first guide vane 41 and the curved structure of second guide vane 42 are stated, is set at the top of helical blade 3 in left and right, institute
It is 2.8 to state the ratio between the first guide vane length H1 and described second guide vane length H2:1；It is between the helical blade 3
Angle A is 60 degree.The wherein described quantity of helical blade 3 is 6.Wherein described fixed installation plate 21 quantity is 6.
Compared with prior art, beneficial effects of the present invention are：
Using the structure of multigroup propeller blade, six helical blades can increase substantially the propulsive efficiency of propulsion plant,
And 60 degree of angles between helical blade when being set using flow direction it is steady, be conducive to the steady of flow field around propeller hub
It is fixed.Proved by up to ten thousand scientific experimental datas, when the first guide vane length H1 and the second guide vane length H2 it
Than for 2.8:When 1, the ambient water of propeller is most stable, high degree reduce turbulent flow generation possibility, greatly improving makes
Use efficiency.Uniqueness is provided with deflector, can stablize the flow field behind propeller hub when using, can substantially improve around propeller hub and
Flow field behind propeller hub；Two flow field guide vanes are using unique arcuate structure.
Above example is served only for that the present invention is further described, it is impossible to be interpreted as the limit to the scope of the present invention
System, some nonessential modifications and adaptations that those skilled in the art makes according to the above of the present invention belong to this hair
Bright protection domain.
