Description
Technical field
The present invention relates to a kind of propelling unit, relate in particular to a kind of rotary wings propelling unit peculiar to vessel.
Background technology
Screw propeller rotates, 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 wake flow 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.
Existing a plurality ofly both at home and abroad adopt the dull and stereotyped patents as marine propeller, for example US Patent 4,102,293, by producing bionical Weis-Fogh effect, provide thrust forward for boats and ships.Propelling unit by this mechanismic design is no doubt efficient, 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, identical with screw propeller tailspin stream, be also a kind of loss of energy.
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 object of the invention is in order to reduce capacity loss, improve propulsion coefficient and a kind of rotary wings propelling unit peculiar to vessel is provided.
The object of the present invention is achieved like this: comprise reciprocating main shaft, S. A. and two blades that are arranged on rotating shaft terminal, also comprise and advance box body and box slideway, on box slideway, be provided with box slideway water-resisting wall, described box slideway arranges box slideway breach in a side of water-resisting wall, reciprocating main shaft is inner at box slideway by the reciprocating spindle mounting hole frame on water-resisting wall, the axle head of the reciprocating main shaft inside that is connected is provided with the profile of tooth frame of tooth bar, profile of tooth frame outer setting advances box body, and advance on box body and be provided with the hole adapting with reciprocating main shaft diameter, reciprocating main shaft is connected through this hole and profile of tooth frame, described propelling box body is arranged on box slideway, S. A. is by advancing the S. A. mounting hole on box body to be arranged on propelling box body, described S. A. interlude is gear wheel shaft, the tooth bar engagement of gear wheel shaft and gear frame.
The present invention also comprises some architectural features like this:
1. described in, the cross sectional shape of blade is hydrofoil shape.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is guaranteeing to provide under the prerequisite of the required thrust of vessel motion, after ship, by reciprocating main shaft drives rotary wings, periodically along box slideway, seesawed, in the process seesawing, in slideway first and last end by advancing gear mechanism in box body to drive rotary wings to change between vertical and horizontal two states.When rotary wings is during in plumbness, main shaft drives advances box body together along slideway, to move backward together with rotary wings, promote to move after current direction, thereby provide thrust forward, when rotary wings is during in horizontality, main shaft drives advances box body together along slideway adverse current, to travel forward together with rotary wings, and because rotary wings is hydrofoil shape, water resistance is less.Compare with conventional propeller, rotary wings propelling unit peculiar to vessel of the present invention can effectively avoid producing tailspin stream, reduces degradation of energy.Under the overall background of nowadays energy-saving and emission-reduction, this propelling unit has good development prospect.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail.
In conjunction with Fig. 1～4, the present invention includes and comprise reciprocating main shaft 2, S. A. 7 and two blades that are arranged on S. A. 7 two ends, S. A. 7 and two blades have formed rotary wings 1, also comprise and advance box body 3 and box slideway 4, on box slideway 4, be provided with box slideway water-resisting wall 6, described box slideway 4 arranges box slideway breach 5 in a side of water-resisting wall 6, reciprocating main shaft 2 by the reciprocating spindle mounting hole frame on water-resisting wall 6 in box slideway 4 inside, the axle head of reciprocating main shaft 2 inside that is connected is provided with the profile of tooth frame 10 of tooth bar, profile of tooth frame 10 outer setting advance box body 3, profile of tooth frame 10 can advance box body 3 internal motions along with the motion of reciprocating main shaft 2, move to and advance the front end face of box body 3 or aft end face realize reciprocating main shaft 2 drive profile of tooth frames 10 and advance box body 3 together to move forwards or backwards, and advance on box body 3 and be provided with the hole adapting with reciprocating main shaft 2 diameters, reciprocating main shaft 2 is connected through this hole and profile of tooth frame 10, described propelling box body 3 is arranged on box slideway 4, S. A. 7 is by advancing the S. A. mounting hole on box body 3 to be arranged on propelling box body 3, described S. A. 7 interludes are gear wheel shafts, the tooth bar engagement of gear wheel shaft and profile of tooth frame 10.
The present invention is when working process: reciprocating main shaft 2 drives rotary wings 1 periodically along box slideway 4, to seesaw, in the process seesawing, in box slideway 4 first and last ends by advancing gear mechanism in box body 3 to drive rotary wings 1 to change between vertical and horizontal two states.When rotary wings 1 is during in plumbness, reciprocating main shaft drives advances box body 3 together along slideway, to move backward together with rotary wings 1, promotes to move after current direction, thereby thrust is forward provided.When rotary wings 1 is during in horizontality, main shaft 2 drives and advances box bodies 3 together along slideway 4 adverse currents, to travel forward together with rotary wings 1, and because rotary wings 1 is hydrofoil shape, water resistance is less.
As shown in Figure 2: box slideway water-resisting wall 6 can be realized water-stop, reciprocating main shaft 2 is passed through by reciprocating spindle mounting hole on box slideway water-resisting wall 6, spacious pool at box slideway 4, box slideway breach 5 can make rotary wings 1 and advance the 3 front and back gliding motilities of box body, and box slideway 4 front ends and hull afterbody are realized seamless connection.
As shown in Figure 3: rotary wings 1 by interlude be gear wheel shaft the blade of two similar hydrofoils of S. A. 7 connected symmetrical dendrimers form.
As shown in Figure 4: profile of tooth frame 10 is outside for advancing box body 3, and the tooth bar in the gear wheel shaft of the interlude of S. A. 7 and profile of tooth frame 10 strictly coincide.
As shown in Figure 5: when reciprocating main shaft 2 has just started to move backward, by gear drive rotary wings 1, from horizontality, become plumbness, in this process, the stroke of reciprocating main shaft 2 is 1/4 S. A. girth, now gear frame 10 ends contact with box body aft end face 9 and promote to advance box body 3 together with the rotary wings 1 in plumbness with speed V
zmotion backward, promotes to move after current direction, thereby thrust F is forward provided, and thinks speed of incoming flow V
0with ship's speed V
pidentical.
As shown in Figure 6: when reciprocating main shaft 2 moves to maximum stroke place along slideway 4, start to travel forward, from reciprocating main shaft 2, drive rotary wings 1 to become horizontality from plumbness at first, the stroke of reciprocating main shaft 2 is also 1/4 S. A. girth, now gear frame 10 contact with box body front end face 8 and drive advance box body 3 together with the rotary wings 1 in horizontality with speed V
zalong slideway adverse current, travel forward, because rotary wings 1 is hydrofoil shape, water resistance is less.
