Abstract
The utility model belongs to the technical field of marine engineering, which relates to a small boat formed by that a foot pedal manual crankshaft rotates and drives a change-speed gearbox for speed increase, wherein the small boat is driven by a transmission shaft and a shaft coupler and is propelled by a propeller. Compared with paddling, scull rowing and a foot pedal paddle wheel small boat, a foot pedal propeller has higher propulsion rate and speed, the running is stable, a direction steering wheel turns right, the foot pedal crankshaft can be treaded positively and reversely, and the small boat can advance or back up or reduces the speed and stop. The foot pedal propeller can be extensively used in production, life, traveling and parks. The lower part of a bow of the foot pedal propeller is provided with a side pushing propeller, when the side pushing propeller is driven manually, the boat can be turned leftward and rightward in place.
Description
One, technical field: the utility model belongs to field of ship engineering, and the foot-operated crankshaft revolution of a kind of specifically manpower footpath speed-change gear box speedup drives the little type ship that screw propeller advances.
Two, background technology: present widely used little type ship: paddle is arranged, the foot-operated paddlewheel propulsion that has of sculling is arranged, it is not high that these ships all exist propulsion coefficient, and the shakiness of travelling turns to inaccurate.
Three, summary of the invention: technical solutions of the utility model foot operated propeller, it is characterized in that foot-operated bent axle being installed at the keel of hull, the finishing bevel gear cuter change speed gear box is installed in the middle of bent axle, behind change speed gear box, there is the transmission shaft coupler to connect propeller shaft, the propeller shaft outboard is partly installed screw propeller, be provided with yaw rudder in back seat the place ahead, form by last lower link and tween drive shaft and yaw rudder.
The utility model foot operated propeller basic scheme and multiple flexible program are realized its purpose.Basic scheme is a foot operated propeller, principle of work is: the people that steers a ship produces by foot-operated bent axle and rotatablely moves and moment, drive screw propeller by the speed-change gear box speedup and produce thrust formula pulling force, bent axle is back-pedalling just, ship is advanced and fall back (or slow down bring to), concrete drive path is: foot-operated bent axle → speed-change gear box → drive coupling → transmission shaft → propeller shaft → screw propeller, the direction control path is: rudder horn (dish) → lower link → tween drive shaft → top rod → yaw rudder.The transmission of thruster screw propeller is: the hand wheel → vertical shaft → gear mesh → cross moving axis → thruster screw propeller
Beneficial effect: 1, foot-operated propeller advances than paddle, sculls, rides, and paddle wheel speed is fast.2, the continuous working of propeller axial advance is than propulsion coefficient height at intermittence.3, the output leg strength of manpower is greater than arm strength.4, need not driving license, everybody can operate.5, foot-operated shipping agency can free by handle, but the operation while advancing.6, because of no internal combustion engine drive, no waste gas and water pollution.7, thruster screw propeller pivot stud.8, need not study, can be widely used in the floods rescue and use.
Four, description of drawings: Fig. 1 is the structure design principle figure of foot operated propeller.Among the figure 1, foot-operated bent axle, 2, the commutation step-up gear, 3, transmission shaft, 4, drive coupling, 5, rudder horn, 6, go up lower link, 7, screw propeller, 8, yaw rudder.9, thruster screw propeller 10, transmission shaft 11, gear mesh 12, the moving axis 13 of writing a biography, the hand wheel
Five, the specific embodiment: 1, selected product specification scheme, 2, deisgn product constructional drawing, 3, according to overall dimension and annex size design assembly drowing, 4, according to assembly drowing folding picture detail drawing, 5, the inspection during manufacture part, 6, the assembling weldering presses hull, 7, part and decoration are installed, 8, product quality inspection, 9, get three cards and go into operation, 10, the tissue products production and sales.
Claims (5)
1, a kind of foot operated propeller, it is characterized in that: in foot-operated spiral shell slurry ship hull, foot-operated bent axle is installed, the finishing bevel gear cuter change speed gear box is installed in the middle of bent axle, transmission shaft is arranged behind change speed gear box, the outboard of drive coupling connecting bolt slurry axle, propeller shaft partly is equipped with screw propeller, direction lever is arranged before back seat, form by last lower link, tween drive shaft and yaw rudder.
2, foot operated propeller according to claim 1, its feature bent axle are made up of bearing crank, stretcher, and the supporting-point of the right and left of bent axle is installed on the bilge bone of ship, and two fulcrums connect with the gear case transverse axis in the middle of the bent axle.
3, according to the described foot operated propeller of claim 1, its feature gear case is by gear-box case, axle drive shaft, big bevel pinion, bearing and sealing member composition.
4, foot-operated spiral shell slurry ship according to claim 1, its feature transmission output shaft spiral shell slurry axle connects with universal coupling.
5, according to the described foot-operated spiral shell slurry ship of claim 1, its feature has the thruster propeller by transmission shaft at bow, and finishing bevel gear cuter is right, vertical shaft and the hand composition of taking turns.
