Abstract

The invention relates to a boat pushing device, which is formed by combining a mechanism, a synchronous belt support shaft and a plurality of paddles, wherein the mechanism consists of a disc-shaped box body, a direct current electric motor, a control device, synchronous belt wheels and a synchronous transmission belt, and the paddles are placed outside the box body. When the direct current electric motor placed in the center of the disc-shaped box body is driven to do anticlockwise revolution by the control device, the synchronous belt wheel Z<xing> arranged in the box body is simultaneously driven to do anticlockwise autoroatation under the effect of bearing shafts and the synchronous belt wheel Z<tai>, the paddles which are arranged at two sides of the disc-shaped box body and are fixedly connected with the bearing shafts can always pull the water at the highest efficiency one after another in a state of being vertical to the horizontal plane, and a boat is pushed to move forwards. Because the pushing device disclosed by the invention always goes forwards through pulling the water at the upper layer of the water level, sludge and sewage dregs at the bottom of a river channel cannot be stirred up, and the boat pushing device has the characteristics that the energy is saved, and simultaneously, the environment is protected.

Description

A kind of marine propulsion

Technical field

The present invention relates to a kind of marine propulsion, the marine propulsion that particularly combines by DC machine and synchronous pulley epicyclic transmission mechanism.

Background technology

Since the mankind invented boats and ships, the quality of propelling unit was directly connected to the speed of boats and ships gait of march and the height of work efficiency.Influence degree to environment becomes a kind of important techniques index again in recent years.Current, common marine propulsion mainly contains hand paddle, hand big shield, hand punt-pole, sail, paddle wheel and screw propeller etc.Wherein, the most popular propeller plant that also belongs to.Be characterized in simple in structure, volume is little, easy to use.But its shortcoming is, when high-speed operation, can produce the cavity phenomenon, seriously hindered boats and ships and developed to high speed.Particularly screw propeller boats and ships propelling unit all is installed in the below of boats and ships tail end usually, must pull the plug fully, therefore, should not in the navigation channel of shallow water, use.Special in the winter of cruiseway, owing to cause that the navigation channel river is very shallow low water season, the boats and ships that cause screw propeller to advance can't normally navigate by water.The shape of each sheet blade is a space spiral curved surface in the propeller plant in addition; The component of its meeting output X, Y, three directions of Z when work; Wherein advance the effective power that boats and ships advance except that the component of a direction can produce, all the other two component all do be unfavorable for that boats and ships advance stir the water motion, not only consumed a large amount of energy and flogged a dead horse; Especially harm is that ship is crossed part and can the general water surface of going up of all backward, corrupt and reactionary things that be deposited in river course bottom seriously have been polluted the clean and tidy of river surface.Therefore, the river course in general city does not generally allow the boats and ships navigation at a high speed above that screw propeller advances.

Traditional paddlewheel propulsion device; Since its a plurality of blades all be distributed in radially transmission shaft around; Each sheet blade overall process from the entry to the water outlet when work all will be passed through setting-out, struck and the water lift three phases; Have only when each sheet blade to turn to when being vertical stage with the water surface, the efficient of striking that this blade mode of operation is produced is the highest.When being rotated further, this blade is because no longer perpendicular with horizontal surface again, some power is being done water lift work on it, and this is the normal navigation that is unfavorable for boats and ships.Equally when another adjacent work blade sheet gets in the water; Because this moment, this blade did not turn to horizontal by the vertical stage as yet; Understand some power in its process of in water, striking and doing the setting-out motion, this also is the unfavorable factor that hinders the boats and ships normal operation.Because each sheet blade can not be vertical mode of operation with the water surface in the whole process from the entry to the water outlet at work all the time, so the propulsion coefficient of paddlewheel propulsion device is not too high.So using this device in the existing market is rare as angle of rake boats and ships aquatic foods.

Summary of the invention

The purpose of this invention is to provide a kind of similar paddle steamer propelling unit, but the energy-efficient environmental protection again of essential distinction and the marine propulsion of ability propelled at high velocity are arranged with it.

Technical scheme of the present invention is this device mechanism, the synchronous pulley bolster mainly be made up of DC machine and controller, synchronous pulley and synchronous belt in fully enclosed casing and the casing and is placed on casing blade outward and combines; This casing is disc shaped cavity; Its inside center is equipped with Electrical Bicycle with DC machine and place the outer controller of casing, the main shaft two ends of DC machine all to stretch out outside the casing; Be fixed on the corresponding support of boats and ships tail end or both sides on motionless; And on the circumference shell of this motor be connected in week in an annulus and the disc casing, respectively arrange two synchronous pulley Z that the number of teeth is identical with shape in the both sides of this annulus _OK, but its axial connecting line all passes the synchronous pulley of electrical axis line and annulus both sides Z _OKArrange that 90 ° of phase phasic differences are criss-cross and arrange, a synchronous pulley Z respectively is being connected on the two ends axle journal of DC machine main shaft in casing _TooMotionless, synchronous pulley Z _TooTwo upper and lower with it or left and right synchronous pulley Z _OKLeave a fixed gap at grade and with it in order to avoid work the time interferes.A synchronous pulley Z of homonymy _TooWith other two belt wheel Z _OKBy a synchronous belt they are constituted one group of synchronous belt drive mechanism.At synchronous pulley Z _TooThe synchronous belt lateral surface of both sides respectively has an orienting lug to push down, and the inboard band tooth of synchronous belt can be adjacent at synchronous pulley Z when work all the time _TooIn the teeth groove of circumference both sides, synchronous pulley Z _OKEndoporus be connected with separately bolster cylindrical; And the hole between the annulus wall that is connected on the middle part of each bolster and the motor housing cooperates and is normal-running fit; In two axle journals of bolster and the disc casing two tank wall holes is normal-running fit also, and is provided with seal ring to prevent in dust and the water entering casing.Stretch outside the disc casing at the two ends of each bolster, a slice that is being connected separately blade, and the position of each blade all is in the state of vertical level, is evenly arranged in the both sides of disc casing.

When the operator opened controller DC machine is clockwise rotated on boats and ships, the annulus and the disc casing that then are connected with its shell also drove its in-to-in synchronous pulley Z _OKAnd bolster do the clws revolution around the axial line of motor, and the synchronous pulley Z that is connected on the axle journal of electric machine main shaft two ends _TooThen motionless all the time, respectively there are two synchronous pulley Z its both sides _OKAt synchronous belt and be adjacent under the effect of briquetting and do the C.C.W. rotation around bolster axial line separately.Because synchronous pulley Z _OKWith synchronous pulley Z _TooThe number of teeth just the same, when motor housing drives package unit around fixed synchronous pulley Z _TooWhen the cw public affairs circle, each synchronous pulley Z then _OKAlso at the synchronous pulley Z that centers on separately _TooThe axial line conter clockwise that also centers on synchronously separately when public affairs circle circles certainly; Then being connected in the outer blade of each bolster two ends casing can be all the time with the state perpendicular to horizontal surface; The axial line of wound motor is made plane motion, if place on the horizontal surface central axis plane of this device or concordant with it, then in the entire work process of each sheet blade from the entry to the water outlet; Can strike with attitude all the time, advance so can obtain maximum efficient promotion boats and ships perpendicular to horizontal surface.If the running of reverse drive motor conter clockwise, then each blade also can keep it in the course of the work, promotes boats and ships with peak efficiency all the time and retreats.Though; Can in air, cause waste of power in the every work of blade after water outlet, but the density of air is merely one of six percentages of water tightness as negative work, little of ignoring; So this device can improve the propulsion coefficient of boats and ships fully greatly, and shipping high speed is advanced.In addition, the blade of this device just in the river course upper strata of the water surface strike, when running at high speed, can not cause all backward, corrupt and reactionary things of river bed after ship is crossed the dregs of society gain an upper hand contaminated environment, and the protection bank protection is not damaged.Owing to adopt synchronous pulley driving mechanism, in the disc casing, needn't be used for gear transmission or the indispensable lubricating oil of chain-driving by contain, the noise that is produced when noise is also far below gear transmission or chain-driving work when working simultaneously.

The specific embodiment

Like Fig. 1, Fig. 2, marine propulsion of the present invention shown in Figure 3 mainly is by osed top disc casing (1), DC motor and controller (2) thereof, annulus (3), synchronous pulley Z _OK(4), synchronous pulley bolster; (5), synchronous pulley Z _Too(6), synchronous belt and briquetting (7), blade (8), be formed by combining.

Be fixed on the center shaft two ends of motor in this propelling unit (2) when being connected on the corresponding with it support in boats and ships tail end or both sides (adopting two these drivings device of cover); When driving governor makes the running of DC machine (2) cw; Also make simultaneously the annulus (3) that is connected with it, synchronous pulley Z _OK(4), synchronous pulley bolster (5), synchronous belt and briquetting (7), the outer both sides of disc casing (1) and casing center on the axial line of DC machine (2) main shaft and the synchronous pulley Z that two ends are connected motionless with it with the blade (8) at synchronous pulley bolster two ends _Too(6) make the clws revolution motion, because the synchronous pulley Z of the interior annulus of disc casing (1) (3) upper support _OKBolster be with it normal-running fit, then under the effect of synchronous belt and briquetting (7), can make two upper and lower or left and right synchronous pulley Z of homonymy _OK(4) around fixed synchronous pulley Z _Too(6) make the C.C.W. spinning motion, because synchronous pulley Z _OK(4) with synchronous pulley Z _Too(6) the number of teeth and shape are in full accord, so as synchronous pulley Z _OKWhen (4) the wound motor axis circles as public affairs, also make synchronous conter clockwise around bolster axis separately simultaneously and circle certainly, so this synchronous drive mechanism also has the characteristics of epicyclic transmission mechanism simultaneously.Then make each blade (8) in disc casing (1) two outside make plane motion with the axial line of wound motor (2) under the vertical-horizontal surface state all the time simultaneously; When placing the central axis of this propelling unit above water or when concordant with it, then promote boats and ships with state the most efficiently all the time in the overall process of each blade (8) from the entry to the water outlet and advance.Though can make negative work when every blade leaves to return in the water surface entering air; But since with water in the propulsive force that produces compare can be little of ignoring; Because this propelling unit can be settled 2-8 sheet blade rectangular distribution simultaneously; At the mode of operation that each blade of when work (8) rises one after another, boats and ships are continuously advanced reposefully or retreat.When preventing in water, to work, water can get in the fully enclosed disc casing, in the outside, supporting junction of each bolster and casing water repellant seal ring is housed all.

The invention of this marine propulsion not only can advance shipping high speed to advance efficient, energy-conservationly; Have only half not have in the entry when particularly this propelling unit is owing to work; Second half then floats over above water, so drinking water is very shallow, can solve the difficult problem that river course dry season screw propeller advances unfavorable navigation.In addition, the blade of this device (8) just in the river course upper strata of the water surface strike, when running at high speed, can not cause all backward, corrupt and reactionary things of river bed after ship is crossed the dregs of society gain an upper hand contaminated environment, and the protection bank protection is not damaged.In addition, owing to adopt synchronous pulley driving mechanism, in the disc casing, needn't be used for gear transmission or the indispensable lubricating oil of chain-driving by contain, the noise that is produced when noise is also far below gear transmission or chain-driving work when working simultaneously.
