Detailed description of the invention
Fig. 1 be the utility model can boosting mechanism propeller for watercraft structural schematic diagram.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
Referring to Fig. 1, the utility model provide it is a kind of can boosting mechanism propeller for watercraft, including shaft 1, be set to and turn
The blade 2 of 1 one end of axis, the blade 2 are covered with a storage power cover 3；Several water inlets being circularly and evenly distributed on the storage power cover 3
Hole 4；3 side of storage power cover is connected by bearing 5 with shaft 1, is stored 3 other side of power cover and is equipped with a rectifying tube 6；The rectification
Pipe 6 connects with power cover 3 is stored, and rectifying tube 6 is in right-narrow and left-wide horn-like；6 upper end of rectifying tube is connected with a connecting tube 7；
A velocity hooster 8 is equipped with above the rectifying tube 6, velocity hooster 8 is in right wide left narrow funnel-form；8 lower end of velocity hooster is equipped with one
Rotary sleeve 9, rotary sleeve 9 are placed on outside connecting tube 7；9 inner wall of rotary sleeve is equipped with an annular groove 10；7 outer wall of connecting tube
The positioning ring 11 to match equipped with one with annular groove 10；Shape is enclosed between 11 outer wall of positioning ring and 10 inner wall of annular groove
At a flowing space 12；The flowing space 12 is empty by several limbers 13 being circularly and evenly distributed and 7 inside of connecting tube
Between connect；10 inner wall of annular groove is equipped with several blades 14 being circularly and evenly distributed；8 outer wall of velocity hooster is equipped with
Water conservancy diversion runner 15, water conservancy diversion runner 15 is in the shape of a spiral；7 inner space of connecting tube is empty by drainage hole 16 and 8 inside of velocity hooster
Between connect.
A partition 17 is equipped in the velocity hooster 8；Shunting sky is enclosed between 8 inner wall of the partition 17 and velocity hooster
Between 18, shunt space 18 connect with drainage hole 16；The partition 17 is connected with several isocons 19；The isocon 19 is in the right side
Narrow left wide funnel-form.
The limbers 13 is in a circular table shape, and limbers 13 is greater than the neighbouring stream in limbers 13 adjacent to one end diameter of connecting tube 7
One end diameter in dynamic space 12；The drainage hole 16 in it is right it is wide under it is narrow round table-like.
The application method of the utility model is as follows:
After shaft 1 starts rotation under the driving of engine, engine will drive blade 2 to rotate, as blade 2 revolves
Turn, whirlpool will be formed by storing in power cover 3, to generate suction, the water flow stored outside power cover 3 is drawn into and is stored in power cover 3, and to the right
It is delivered in rectifying tube 6, since rectifying tube 6 is in right-narrow and left-wide horn-like, as rectifying tube 6 constantly narrows, entrance is whole
Water flow hydraulic pressure in flow tube 6 is continuously increased, and pressurized water flow can then enter at the first time in connecting tube 7, and directly pass through
Limbers 13 enters in the flowing space 12, and pressurized water flow can then push blade 14, thus make rotary sleeve 9 as
Impeller generally rotates, and when rotary sleeve 9 rotates, velocity hooster 8 rotates therewith, at this time the presence of water conservancy diversion runner 15
Velocity hooster 8 can be then set to form a whirlpool bigger than the whirlpool that blade 2 is formed when rotated.
After forming whirlpool outside velocity hooster 8, since velocity hooster 8 is in right wide left narrow funnel-form, rectifying tube 6 is in right-narrow and left-wide
It is horn-like, be capable of forming the structure of a hourglass between velocity hooster 8 and rectifying tube 6, therefore velocity hooster 8 and rectifying tube 6 are opposite
A side position diameter it is minimum, the whirlpool that velocity hooster 8 is formed will be directly transferred to position at this, be made centered on position at this
Whirlpool constantly generates, and whirlpool has an impact rectifying tube at this time, and rectifying tube 6 can be rotated freely under the action of bearing 5,
Velocity hooster 8 and rectifying tube 6 form twice rotation, and the range of whirlpool can be made to further increase, thus make whirlpool generate thrust into
One step improves, while entering high pressure water flow a part in connecting tube 7 by drainage hole 16 directly into velocity hooster 8, is formed
Column water flow is improved final propulsive force again, and the column water flow makes extraneous water flow under the protection of velocity hooster 8
Influence to it is preferably minimized, and guarantees the propulsive force of the formation of column water flow.
In summary it is found that the utility model can be pressurized by the water flow that blade 2 pushes by 6 Duis of rectifying tube, and benefit
Rotary sleeve 9 is rotated with pressurized water flow, velocity hooster 8 is enable to form the whirlpool of tremendous range by water conservancy diversion runner 15
Whirlpool enables propulsive force to be at this time far longer than blade bring propulsive force, and in rectifying tube to obtain enough propulsive forces
Under 6 rotation auxiliary, propulsive force can be further increased, while the column water flow being discharged from drainage hole 16 being made to improve propulsion again
Power can equally guarantee that propulsive force can reach greatly, play the effect of boosting mechanism even if propeller itself rotates relatively slowly,
To avoid engine from being chronically at the case where service life is easily shortened in high power state rotation, when engine problem is only capable of low function
When rate rotates, the propeller of the utility model can then generate enough propulsive forces, and ship is made to be detached from sea in the shortest time,
Prevent security risk.
It is equipped with partition 17 in velocity hooster 8, is enclosed between 8 inner wall of partition 17 and velocity hooster and shunts space 18, shunts empty
Between 18 connect with drainage hole 16, partition 17 is connected with several isocons 19, and the presence of isocon 19 can not only be to entering
The water flow shunted in space 18 is shunted, and a plurality of column water flow is obtained, so that multiple tracks propulsion is obtained, to the full extent to propulsion
Power is promoted, and isocon 19 is in right-narrow and left-wide funnel-form, and water flow can be continuously available pressurization when flowing through isocon 19,
Make the water flow for spraying isocon 19 that there is great propulsive force.
Limbers 13 is in a circular table shape, and limbers 13 is greater than the neighbouring flowing sky in limbers 13 adjacent to one end diameter of connecting tube 7
Between 12 one end diameter, drainage hole 16 in it is right it is wide under it is narrow round table-like, therefore when water flow flows through connecting tube 7, most of water flow is then
It can be split to the flowing space 12, to guarantee the rotation of rotary sleeve 9, velocity hooster 8 be enable to play speedup effect.
