Abstract

The utility model provides a paddle wheel propeller for a ship. The paddle wheel propeller for the ship comprises a wheel axle. The wheel axle is provided with a driven wheel, a left driving wheel and a right driving wheel. A plurality of paddles are arranged between the left driving wheel and the right driving wheel. The paddles are installed between the left driving wheel and the right driving wheel through bent axles. The bent ends of the bent axles are connected with the driven wheel. An eccentric angle adjustment plate and an eccentric angle adjustment rod which are used for adjusting the angle between the paddles and the water level are arranged in the driven wheel, so the direction of propelling force set for a ship body can keep constant in the whole effective travelling process of propelling of each paddle in water. The paddle wheel propeller for the ship has the advantages of being simple in structure, good in using effect and the like.

Description

A kind of boats and ships are used the paddlewheel propulsion device

Technical field

The utility model relates to a kind of marine propeller.

Background technology

The propelling unit that existing power vessels is used mostly is screw propeller; It is not enough below this propelling unit exists; The one, because the screw propeller displacement is little, can only improve drainage speed through strengthening rotating speed, to obtain the power that necessary propelling boats and ships advance; But screw propeller can cause turbulent flow in rotary course, causes the significant wastage of the energy.The 2nd, the boats and ships that adopt screw propeller in the process of moving, water is very big to the resistance of ship, influences the route speed of ship.

The utility model content

The purpose of the utility model is exactly to above-mentioned situation, provides a kind of boats and ships to use the paddlewheel propulsion device, and this paddlewheel propulsion device can not only reduce the formation of turbulent flow, and can reduce the resistance of water to boats and ships, accelerates the route speed of boats and ships, improves the propulsion coefficient of boats and ships.

The purpose of the utility model can come this existing through following scheme: a kind of boats and ships are used the paddlewheel propulsion device; Comprise wheel shaft; On wheel shaft, be provided with flower wheel, left driving wheel and right driving wheel; Between left driving wheel and right driving wheel, be provided with several blades, between left driving wheel and right driving wheel, the end of the bending of bent axle is connected with flower wheel blade through crankshaft installed; In flower wheel, be provided with an eccentric angle regulating plate and eccentric angle adjust bar and be used for regulating the angle between blade and the horizontal surface, make the direction of each blade propulsive force that maintenance is set to hull all the time in the whole effective travel that entry advances constant.The utlity model has simple in structure, characteristics such as result of use is good.

The specific embodiment

Map 1, Fig. 2, Fig. 3 can know; A kind of boats and ships are used the paddlewheel propulsion device; Comprise wheel shaft 1, on wheel shaft 1, be provided with flower wheel 2, left driving wheel 3 and right driving wheel 4, between left driving wheel and right driving wheel, be provided with several blades 5; Blade 5 is installed between left driving wheel and the right driving wheel through bent axle 6; The end of the bending of bent axle is connected with flower wheel, in flower wheel, is provided with an eccentric angle regulating plate 7 and eccentric angle adjust bar 8 and is used for regulating the angle between blade and the horizontal surface, makes the direction of each blade propulsive force that maintenance is set to hull all the time in the whole effective travel that entry advances constant.

The utility model principle of work is following: when the angle of blade maintenance and horizontal surface is the state motion of 90 degree; The wheel shaft diametral load that the big extremely portion of propelling rate that blade produces hull in the effective travel of entry is a level; Therefore propulsion coefficient obviously is higher than traditional paddle wheel; When blade be adjusted to horizontal surface with less than 90 degree greater than casterangle when running of 0 degree; Blade will produce the upwards component of lifting hull in the wheel shaft diametral load of the level of generation; This component strengthens with the increase of speed raising, the blade casterangle number of degrees and the blade underwater penetration (maximum is no more than the radius of driving wheel) of blade running, and when this component went out the water surface with the hull lifting, hull had just been broken away from the resistance of motion of water to hull when motion; The component of this lifting hull that is produced by propulsive force is with obviously different by the component of the lifting hull of water resistance generation, and the effect of comparing is also obvious.Go out also can make under the buoyance boats and ships to realize the efficient high-speed navigation in this hull lifting.Because this propelling unit is a wheeled construction; Can be many in the use to the both sides of balanced configuration at ship; Therefore be adjusted to by the eccentric angle regulating plate under the state that blade do not exceed driving wheel lower end outer rim when blade, driving wheel can go on the land route as wheel, makes boats and ships can possess certain amphibious function.In addition, on boats and ships, set up the deflecting plate that matches and use with the utility model, also can avoid current to be in the non-effective travel impact blade at blade.
