Description
Technical field
The present invention relates to a kind of blade construction, more particularly to a kind of branch type propeller blade.
Background technology
Instantly the blade of most propeller for vessels is all monoblock cast, and such blade surface pressure distribution is uneven
It is even, and it is very easy to produce the unfavorable phenomenon of fluid separation, propulsive efficiency is not high." ship is proposed in nowadays international shipping circle
Under the overall situation of the ship such as energy-saving and emission-reduction " and " green ship " development new ideas, a kind of efficient Novel spiral blade is developed
Piece will be highly desirable to and very significant.
The content of the invention
The invention aims to provide a kind of branch type propeller blade, the conventional ship of homotype can be produced in guarantee tool
On the premise of the thrust provided with propeller, by adjusting the relative position of additional blades and primary blades, make to flow around propeller
Body formation is interfered, and is improved primary blades and is added the efficiency of blade.
The object of the present invention is achieved like this:Including oar axle and the primary blades being symmetricly set on oar axle, the oar axle
It is groomed oar axle, is provided with thin axle, thin axle in it and is provided with around ring, and is located at around ring between oar axle and thin axle, the main lobe
Piece is that hollow and primary blades ends settings are fluted, and the groove is communicated with the hollow space of primary blades, described outside ring
Surface is symmetrically arranged with connecting rod, and the number of connecting rod is equal with the number of primary blades, and connecting rod passes through hollow primary blades, Mei Gelian
The end of bar is provided with additional blades, and additional blades are located in the groove of primary blades, and a jack, main lobe are set on each connecting rod
The hollow inner surface setting of piece has row's mounting hole corresponding with jack, and jack in any one mounting hole with being provided with latch.
Present invention additionally comprises some such architectural features:
1. described in primary blades have three, corresponding groove, connecting rod and additional blades also have three respectively.
2. described in row's mounting hole number be three.
Compared with prior art, the beneficial effects of the invention are as follows:The present invention is one kind to traditional normal spiral paddle blade
Improve, be mainly made up of the part such as oar axle, primary blades, additional blades, distance adjustor.The blade of the present invention is by traditional common spiral shell
Additional blades are installed in primary blades obtained from cutting out on the basis of rotation paddle blade to obtain, the position of additional blades is controllable.Work as spiral shell
Blade is rotated with given pace during rotation oar work, and the smaller additional blades in primary blades also follow rotation, due to it can control in
Between the distance between additional blades and primary blades guide margin, lagging edge, utilize the mobile regulation additional blades surrounding fluid of additional blades
Motion, realize the favourable interference between primary blades and additional blades, improve the efficiency of propeller, save the energy.This novel spiral
The characteristics of rotation oar has simple in construction, good energy-conserving effect, has good actual application prospect on above water craft.
Brief description of the drawings
Fig. 1 is branch type propeller blade normal cross-section schematic diagram of the invention;
Fig. 2 is the structural representation of the section in the branch type propeller blade A-A1 directions of the present invention;
The structural representation that Fig. 3 cuts open for the face in the branch type propeller blade B-B1 directions of the present invention.
In figure:Jack, 8 main lobves of 1 additional blades, 2 connecting rods, 3 primary blades, 4 oar axles, 5 in ring, 6 thin axles, 7 primary blades
Piece hollow space, 9 latches.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1 to Fig. 3, branch type propeller blade of the invention is by primary blades 3, additional blades 1 and distance adjustor group
Into, 1 less additional blades is adhered in a primary blades, can be by coupled roll adjustment dress in middle additional blades
Put and control itself and primary blades guide margin, the distance with edge direction, a part is removed on the basis of normal spiral paddle blade for installing
Some is empty in the middle of additional blades and distance adjustor, primary blades, is available for connecting rod to swing wherein, and motion is provided to swing
Space.Connecting rod inserts for latch with being provided with jack in primary blades, connecting rod and additional blades is fixed with this.Namely primary blades are installed
On oar axle 4, distance adjustor is arranged on the hollow space of primary blades, and additional blades are connected with distance adjustor, installed in primary blades
In the position being recessed after cropped namely groove, distance adjustor includes jack 7, around ring 5, thin axle 6 and connecting rod 2 etc..
The blade of the present invention is made up of primary blades 3, additional blades 1, and primary blades 3 drive rotation by oar axle 4, produces thrust,
It can be deformed close to blade tip segment fluid flow when rotated, deflecting, fluid can be by adjusting accessory lobe when flowing through additional blades 1
The position of piece 1, which makes fluid change interfering between its speed, direction, fluid, can make blade when rotated by less resistance
Power.The position of additional blades 1 is adjusted by distance adjustor, the lower end of governor motion be around ring 5, around ring 5 can around with oar axle 4
The thin axle 6 being fixedly connected with is rotated, so connecting rod 2 can do the rotary motion of certain angle in the hollow space 8 of primary blades 3,
When additional blades 1 move to correct position, 9 are inserted in the jack 7 of connecting rod and the jack 7 of primary blades come under fixing by latch
The position of additional blades 1.
The present invention branch type propeller blade control principle be:In advance according to different operating modes the need for, determine accessory lobe
The correct position of piece 1.Change the position of additional blades 1, this process is by removing latch 9, swing connecting bar 2, by latch 9
Different jacks 7 in insertion primary blades are completed.Rotated around ring 5 around thin axle 6, oar axle 4 drives blade to rotate.
