Abstract
The utility model provides a promoting propeller for a ship. The promoting propeller comprises a reciprocating main shaft, two promoting blades and a rotating shaft. Two linkage rings are arranged on one side of each promoting blade. The rotating shaft is fixedly connected with one end of the reciprocating main shaft. The two promoting blades are arranged on the rotating shaft in a sleeved-staggered mode through linkage rings respectively. By improving back wake flow of the propeller, wake rotational flow and cross flow are avoided, energy loss is lowered, propelling efficiency is improved, compared with a traditional propeller, the propeller does not generate wake rotational flow, energy loss is low, propelling is high, and under the current general background of energy conservation and emission reduction, the promoting propeller has great practical using prospect.
Description
Technical field
The utility model relates to a kind of propelling unit, relates in particular to a kind of propelling unit of agitating peculiar to vessel.
Background technology
Existing propelling unit is mainly to rely on screw propeller to rotate, and when propelling fluid moves backward, fluid has been produced and rotatablely moves.It is that screw propeller generation thrust is necessary that propelling fluid moves backward, and rotatablely moving of the wake flow that screw propeller produces is a kind of energy dissipation completely.Wake flow the consumed energy that rotatablely moves can reach the more than 15% of main engine power conventionally.In addition, common screw propeller ubiquity rotating speed strong noise is large, and water side produces larger resistance to boats and ships greatly, and complex process processing and manufacturing difficulty is large.
Had both at home and abroad much the patents about marine propeller aspect, the Device for propelling ships that for example US Patent No. 4102293 is announced, relies on the routing motion of reciprocal axle and blade, can provide thrust forward for boats and ships.But still there is a little deficiency, first because hull travels forward, when when propelling unit opens, adverse current moves ahead, produce larger resistance, secondly in the process of " sumo is opened with anxious ", easily produce lateral flow, this just can produce tailspin with screw propeller rotary current and flow identical, also be a kind of loss of energy, and its structure relative complex.
Nowadays vigorously advocating under the large background of energy-saving and emission-reduction, the energy-conservation propelling unit of development of new avoids producing the important subject that unnecessary rotary current and lateral flow become ship energy saving.
Summary of the invention
The purpose of this utility model is in order to reduce degradation of energy, improves propulsion coefficient, and a kind of propelling unit of agitating peculiar to vessel is provided.
The purpose of this utility model is achieved in that and comprises that reciprocating main shaft and two agitate blade, also comprise S. A., described in each, agitate a side of blade to have two shackles, S. A. is fixedly connected with one end of reciprocating main shaft, agitates blade by shackle, to be interlocked and be enclosed within on S. A. respectively for two.
The utility model also comprises some architectural features like this:
1. described in, S. A. comprises interior axle, is arranged on the S. A. shell of interior axle outside and is fixedly connected on the balancing needle at interior axle midway location place, described in agitate blade to be enclosed within on S. A. to refer to and agitate blade to be enclosed within on interior axle.
2. in the middle of two shackles of reciprocating main shaft both sides, torsion spring is installed.
3. liang agitate position corresponding with reciprocating main shaft on blade to have blade draw-in groove.
Compared with prior art, the beneficial effects of the utility model are: relatively traditional propeller, propelling unit of the present utility model adopts reciprocating main shaft, two to agitate blade and S. A. combined action, agitate blade around S. A., to rotate under flow action for two, thereby the opening and closing of property performance period, the utility model can not produce tailspin stream, so degradation of energy is in the course of the work few, propulsion coefficient is high, noise cavity function admirable; And it is simple in structure, be easy to realize, under the overall background of nowadays energy-saving and emission-reduction, the utlity model has good actual application prospect.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
Accompanying drawing 1-6 has provided the angle of rake concrete structure schematic diagram of agitating peculiar to vessel of the present utility model, and S. A. 2 is fixed on reciprocating main shaft 1, and blade draw-in groove 6 is used for controlling agitates the maximum bubble flare of blade 3, coincide with main shaft 1 camber line.Breach 4 on S. A. shell 10 is identical with the attaching parts width of blade shackle 8, but be slightly less than shackle 8 width, to realize sealing, prevents into water.Balancing needle 11 is for guaranteeing that two blades can be in Chuan Zhongchu when closing up; Torsion spring 9 two ends agitate the shackle 8 of blade 3 to be fixedly connected with two respectively, have the trend of mutually closing up to two blades, and while guaranteeing that main shaft 1 travels forward, two blades can close up completely, thereby reduce corresponding fluid resistance.Accompanying drawing 4 is propelling unit rigid connector, and wherein in reciprocating main shaft 1, rotation, axle 7 and balancing needle 11 can adopt integrated production, guarantee the steadiness of structure, and S. A. shell 10 is connected with main shaft 1 by the mode of welding.Accompanying drawing 5 is two blade construction schematic diagrams of the present utility model, two agitate blade all the shackle 8 different from two width be connected, annulus width is partially got 2/3～3/4 of inclined to one side outer toroid width, accompanying drawing 6 is axle construction schematic diagram in S. A. of the present utility model, because adapter shaft is thinner, the shorter intensity that guarantees rotating shaft of adapter shaft in partially.
Propelling unit of the present utility model mainly relies on the mutual motion of propelling unit and current to realize under the effect of current and agitates opening and closure of blade 3.Think that ship navigates by water in hydrostatic, propelling unit speed of incoming flow V
0size equals ship's speed V
pand opposite direction.Accompanying drawing 7 is the force diagram while agitating propelling unit to open, and when reciprocating main shaft 1 moves backward, under phyllocyst flow force F effect, agitates blade 3 to open, in order to make blade realize soft opening, and the speed V that main shaft 1 moves backward
zby zero, accelerate finally to reach gradually 4 times of ship's speed V
p, and produce maximum thrust F
t, move to maximum stroke always.Speed variation tendency when accompanying drawing 8 moves backward for main shaft 1 of the present utility model.
In main shaft 1 accelerator, accompanying drawing 9 is for agitating blade 3 to be flared to gradually maximum open configuration.
Accompanying drawing 10 is the force diagram while agitating propelling unit closed, and when propelling unit travels forward, rotating shaft 2 travels forward with 1 times of ship's speed, under bourn acting force F effect, agitate blade 3 to close gradually reality, the blade 3 of agitating after closing is in fact hydrofoil shape, and fluid resistance is less, can effectively reduce resistance.
