Abstract
The pedal racing boat is composed of boat body, cowling, seat chair, pedal gear disk, meshing gear, propeller and oar-mounting holes. Said new racing boat mainlg uses the pedal force as driving power, and if necessary, also can use upper limbs drive as power. Under the condition of propeller driving, the pedal gear disk is pedaled to drive the gear meshed with shaft head of the propeller to make it rotate, then the propeller shaft is used to drive the propeller to make it rotate, and the rotation of said propeller produce thrust force, and the thrust force can act on the boat body by means of thrust bearing so as to propel boat body.
Description
The present invention relates to a kind of pedal racing boat.
The racing boat of competition sports items or canoe racing all use the quant of mainly having an effect by upper limbs to do power at present.As a kind of motion, this type of drive does not have anything can not say completely.
The objective of the invention is for provide a kind of main by lower limb have an effect for drive power, can be the novel racing boat of power also when needing with the upper limbs driving.
The object of the present invention is achieved like this: this racing boat is made up of hull, fairing, seat, foot-operated toothed disc, engaging gear, screw propeller etc.It is characterized in that: be provided with a transparent stackable fairing on the top of hull, to reduce the resistance of air.Postmedian at ship is provided with the adjustable ship hand seat of a distance, on the appropriate location that two of seat the place ahead, ship helped, respectively is provided with the quant placed hole, in order to laying of quant.In the middle front part of ship, the front of ship hand seat, be provided with a foot-operated toothed disc, the gear mesh on this foot-operated toothed disc and the screw propeller spindle nose.Screw propeller places the below at the exterior rear portion of hull by prop shaft, fixed type bearing, thrust baring, fixed support.Step foot-operated toothed disc, the gear that drives on the ingear screw propeller spindle nose rotates, and drives screw propeller by prop shaft again and rotates, and screw propeller rotates the thrust that produces and acts on hull by thrust baring, advances thereby promote hull.
Owing to adopt above design, make this racing boat become a kind of good sports equipment and body-building and converter tools
The present invention is described further below in conjunction with drawings and Examples.
Fig. 1 is the vertical profile view principle scheme drawing of this pedal racing boat;
Driving principle scheme drawing when Fig. 2 adopts twin screw to drive for this pedal racing boat;
Hull 1 among the figure, fairing 2, oar placed hole 3, seat 4, rudder joystick 5, pedal 6, foot-operated toothed disc 7, screw propeller spindle nose engaging gear 8, fixed type bearing 9, prop shaft 10, screw propeller axle sleeve 11, fixed support 12, fix and thrust baring 13, rudder 14, screw propeller 15, the foot-operated toothed disc 16 of interior axle, outer shaft is ridden toothed disc 17, axle spindle nose engaging gear 18 in the screw propeller, screw propeller outer shaft spindle nose engaging gear 19, outer shaft 20, outer shaft drives screw propeller 21, fixing and the thrust baring 22 of interior axle, interior axle 23, interior axle drives screw propeller 24.
In Fig. 1, step pedal 6, driving foot-operated toothed disc 7 rotates, this foot-operated toothed disc drives screw propeller spindle nose engaging gear 8 again and rotates, this screw propeller spindle nose engaging gear drives screw propeller 15 by prop shaft 10 again and rotates, screw propeller rotates the thrust that produces and acts on hull 1 by thrust baring 13, advances thereby promote hull.
We know that screw propeller promptly to hull generation one thrust forward, also produces a horizontal torsion to hull simultaneously in the middle of work, and this torsion strengthens along with the raising of propeller speed, and can destroy the balance of ship.In order to overcome this phenomenon, Fig. 2 has provided a kind of pedal racing boat driving principle scheme drawing that adopts twin screw to drive.In the pedal racing boat that this employing twin screw drives, foot-operated toothed disc 7 has been divided into the foot-operated toothed disc 16 of interior axle and foot-operated 17 two the relative foot-operated toothed discs of toothed disc of outer shaft.That prop shaft 10 also is divided into is concentric, be equipped with interior axle 23 and 20 two prop shafts of outer shaft of fixed type bearing between the diaxon.Screw propeller spindle nose engaging gear 8 is divided into axle spindle nose engaging gear 18 and screw propeller outer shaft spindle nose engaging gear 19 in the screw propeller.The foot-operated toothed disc 16 of interior axle meshes with the interior axle of screw propeller spindle nose engaging gear 18, and the foot-operated toothed disc 17 of outer shaft meshes with screw propeller outer shaft spindle nose engaging gear 19.Step pedal 6, driving foot-operated toothed disc 16 and 17 rotates, these two foot-operated toothed discs drive screw propeller spindle nose engaging gear 18 and 19 more respectively and rotate to opposite each other direction, also rotate thereby drive two screw propellers, make screw propeller rotate the torsion that produces and cancel each other to opposite each other direction.
Claims (2)
1, a kind of pedal racing boat, by hull, fairing, seat, foot-operated toothed disc, engaging gear, compositions such as screw propeller, it is characterized in that: be provided with a transparent stackable fairing 2 on the top of hull 1, to reduce the resistance of air, postmedian at ship is provided with the adjustable ship hand seat 4 of a distance, in seat the place ahead, on the appropriate location that two of ship is helped, respectively be provided with quant placed hole 3, in order to laying of quant, middle front part at ship, the front of ship hand seat, be provided with a foot-operated toothed disc 7, engaging gear 8 engagements on this foot-operated toothed disc and the screw propeller spindle nose, screw propeller 15 is by prop shaft 10, fixed type bearing 9, fix and thrust baring 13, fixed support 12 and place the below at the exterior rear portion of hull, step pedal 6, driving foot-operated toothed disc 7 rotates, this foot-operated toothed disc drives screw propeller spindle nose engaging gear 8 again and rotates, this screw propeller spindle nose engaging gear drives screw propeller 15 by prop shaft 10 again and rotates, screw propeller rotates the thrust that produces and acts on hull 1 by thrust baring 13, advances thereby promote hull.
2, pedal racing boat according to claim 1 is characterized in that: when this pedal racing boat adopts twin screw to drive, and the foot-operated toothed disc 16 of axle and foot-operated 17 two the relative foot-operated toothed discs of toothed disc of outer shaft in foot-operated toothed disc 7 is divided into.That prop shaft 10 also is divided into is concentric, be equipped with interior axle 23 and 20 two prop shafts of outer shaft of fixed type bearing between the diaxon.Screw propeller spindle nose engaging gear 8 is divided into axle spindle nose engaging gear 18 and screw propeller outer shaft spindle nose engaging gear 19 in the screw propeller.The foot-operated toothed disc 16 of interior axle meshes with the interior axle of screw propeller spindle nose engaging gear 18, and the foot-operated toothed disc 17 of outer shaft meshes with screw propeller outer shaft spindle nose engaging gear 19.Step pedal 6, driving foot-operated toothed disc 16 and 17 rotates, these two foot-operated toothed discs drive screw propeller spindle nose engaging gear 18 and 19 more respectively and rotate to opposite each other direction, also rotate thereby drive two screw propellers, make screw propeller rotate the torsion that produces and cancel each other to opposite each other direction.
