Description
Technical field
A kind of single-shot flat paddle leaf canoe, belongs to technical field of ships, particularly relates to a kind of flat paddle leaf canoe.
Background technology
Traditional marine propulsion adopts screw propeller mostly, although drive conveniently, efficiency is lower, and blade manufacturing process is complicated, can produce tail during use; The patent No. is ZL200310106145.1, name is called the Chinese patent of biotic plate propoller ship, disclose the dull and stereotyped marine propulsion of a kind of half-rotating mechanism, efficiency is higher, but blade only has a position vertical with front line direction when striking backward, other position and the direction moved ahead are not 90 °, and blade helps the nothing that moves ahead at the component laterally produced, loss part energy, efficiency is not too high.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming traditional canoe, invent the higher single-shot of a kind of efficiency flat paddle leaf canoe.
A kind of single-shot flat paddle leaf canoe, comprises hull, aft rudders, left propelling unit, right propelling unit, control system and power system.Hull adopts timber, glass-felt plastic or carbon fiber composite material to make.Aft rudders is manipulated by control system and canoe is kept straight on or turning driving.Power system comprises a driving engine and reduction gear apparatus, and the power of driving engine passes to left propelling unit and right propelling unit through reduction gear apparatus, drives left propelling unit and right propelling unit constant speed contrarotation to produce thrust.Left propelling unit identical with right propeller structure, parameter and principle of work respectively symmetrical be arranged on the left and right sides of hull underdeck left breach and right breach in, driving engine and reduction gear apparatus are arranged on the deck of hull postmedian.
Right angle of rake concrete structure is: it comprises guide housing, main shaft, pivoted arm, center half gear and is distributed in gear both sides, center half engages with center half gear and is arranged on the rotating vane device of two same structures on pivoted arm.Center half gear is one and only has the toothed gear of half cycle, it is fixedly installed in below deck that the hull above right breach stretches out to the right, the Dai Chiban Zhou Dynasty of center half gear is right, anodontia half Zhou Dynasty is left, the edge radius of anodontia half cycle is less than the tooth paddy radius of band tooth half cycle, in order to avoid the tooth of the nearly heart gear of rotating vane device is through the out-of-date anodontia half cycle touching center half gear.Main shaft is vertically arranged, the stage casing of main shaft is connected in the centre hole of center half gear by bearing and center half gear, flexible rotating in the centre hole of main shaft Neng center half gear; The lower end of main shaft and pivoted arm are fixed on the center of pivoted arm, and the upper end of main shaft is connected with the driving device of power system, and power inputs from the upper end of main shaft.Each rotating vane device comprises nearly heart gear, heart gear far away and blade.Blade is stiff rectangular plate blade.The antifriction cylinder reducing to be close to the energy smart scroll of guide housing inwall cliding friction in two ends, blade left and right is installed in the middle part of the bus limit, two, left and right of blade.The rotating shaft hypomere of heart gear far away is arranged on the tip of pivoted arm by bearing, the rotating shaft lower end of heart gear far away and blade are fixed on center, the upper end place of blade.Blade is vertically arranged, and vertical with heart gear far away.Nearly heart gear is between center half gear and heart gear far away, and the rotating shaft of nearly heart gear is arranged on the middle part between the center of pivoted arm and tip by bearing.Heart gear far away on same rotating vane device and nearly heart gears meshing, its transmitting ratio is 1: 1.Two nearly heart gears engage at Shi Junyu center half, the right side gear of main shaft, and its transmission engage ratio is 1: 1.Guide housing is semicircular arc, keeps left and is fixedly mounted on hull.Guide housing inwall is the smooth arc-shaped surface of line centered by the axis of main shaft, when this arc radius size just makes blade run in the left side of main shaft, the antifriction cylinder at two ends, blade left and right can be close to the rolling of guide housing inwall simultaneously, guarantees that blade remains vertical with pivoted arm from last running in the process at the most front place on the left of main shaft.When assembling right propelling unit, the blade on the right side of when guaranteeing that pivoted arm is in lateral horizontal position is in horizontal vertical position.Due to the right side at main shaft, the transmitting ratio of heart gear far away and center half gear is 1: 1, and center half gear maintains static, and any position of blade on the right side of main shaft all can remain in laterally vertically state.Anodontia at Left-side center half gear of main shaft, by the constraint of guide housing, blade can keep vertical with pivoted arm.
The principle of work of this kind of single-shot flat paddle leaf canoe is: start the engine, drive left propelling unit and right propelling unit to rotate, see from top to bottom and namely overlook this canoe, under the driving of power, right angle of rake main shaft rotates clockwise, and drives right angle of rake pivoted arm clickwise.On the right side of longitudinal vertical guide of the right angle of rake main shaft of mistake, the conter clockwise rotation under the drive of the angle of rake heart gear far away in the right side of right angle of rake blade keeps laterally vertically state to strike backward; In the left side of longitudinal vertical guide of the right angle of rake main shaft of mistake, by the constraint of right angle of rake guide housing, right angle of rake blade keeps front with the angle of rake pivoted arm Vertical dimension in the right side and resets.In like manner, under the driving of power, left angle of rake spindle axis counterclockwise rotation, drives left angle of rake pivoted arm left-hand revolution.In the left side of longitudinal vertical guide of the left angle of rake main shaft of mistake, the cw rotation under the drive of the angle of rake heart gear far away in a left side of left angle of rake blade keeps laterally vertically state to strike backward; On the right side of longitudinal vertical guide of the left angle of rake main shaft of mistake, by the constraint of left angle of rake guide housing, left angle of rake blade keeps front with the angle of rake pivoted arm Vertical dimension in a left side and resets.The deflection of manipulation aft rudders makes this canoe turn.
Advantage of the present invention is: can not produce the obvious tail as propeller during the work of a kind of single-shot of this invention flat paddle leaf canoe, without large spray, and blade easily makes; The propelling unit of this canoe is higher than half-rotating mechanism puopulsion plant efficiency.Adopt a driving engine to be used as power, structure is simple, and cost of manufacture is low.
This canoe is used as marine communication means and all very convenient for physical culture activity of travelling.
