Description

A kind of bottom driving marine propeller

Technical field

Technical field of ships is the utility model is related to, specifically a kind of bottom driving marine propeller.

Background technology

The propeller of propeller generally belongs in the market is directly directly opposite propulsion to water or air acting realization；By The requirement that propeller is limited draft, is limited tradding limit, or other bottom driving propeller direction of propulsion it is limited or Person is other can be larger because the angle of guide grid influences generation in main direction of propulsion with the bottom driving propeller of full circle swinging Waterpower deflecting is lost.

A kind of seesaw boat on water surface of CN201110054558, including hull, floating drum, swing steering mechanism and marine propulsion machine Structure, hull are made up of front tube, middle vertical tube, rear pipe, transverse tube, bridge shape broken pipe, middle transverse tube, anchor ear and panel, and floating drum is fixed by anchor ear In the both sides of hull, swing steering mechanism and be installed on the middle transverse tube and middle vertical tube of mid-ship, swing steering mechanism by sticking up Plate, axle bed, transverse axis, prime bevel gear, rear class bevel gear, vertical pivot and swing rod are formed, after marine propulsion mechanism is connected to swing rod End.

A kind of CN200510137788 toy boat, including：By the propeller (29) of driving source (26) driving, support helix Oar (29) simultaneously plays the propeller bracket (30) of direction rudder action and propeller bracket (30) is turned to the servo of a horizontal level Mechanism (31).The driving source (26) is installed in hull (22).

CN201380061949.6 ships include hull (10) and are suitably coupled to the propulsion dress of ship inner driving device (8) Put (3), it is characterised in that the hull (10) is provided with least one hollow bulb (2), and at least one hollow bulb (2) is fitted Ground shaping is closed to accommodate the propulsion plant (3) at least in part, the hollow bulb (2) is provided with least one pipe (21) and extremely A few atmospheric air entrance (220) so that propulsion plant, i.e. water surface propeller (3) can be relative to so caused people The water surface is made continuously to work at optimum conditions.

CN201410467761 is a kind of mudflat ship, including hull and the propulsion plant that is arranged on hull and turning to fills Put, the transfer is connected on the propulsion plant, and the hull also includes float-up device, and the hull bottom is provided with close Cavity is sealed, the float-up device is connected between the propulsion plant and sealing cavity, and the float-up device is into sealing cavity Compressed media is sprayed so as to hold up hull, and the utility model structure integrally lifts hull by using the air pressure in sealing cavity Rise, reduce the contact area of hull and beach, so as to reduce the frictional force of hull and beach, the impeller direct drive ship on hull Body moves ahead, and without manpower is cost, traveling is simple and convenient quick, and the equally applicable water surface of this hull, may act as simple motorboat and uses.

Existing propeller deflecting ability, when ship needs to turn to, it can be led to using the mode of rudder or deflecting impeller Cross the deflection of current make ship to, but take long enough and very big space be adjusted.Existing propeller is eaten in ship Thrust can reduce in the case that water is shallow, it is impossible to keep strong impetus.Propeller and deflecting impeller are easily faulty, now need Dry-docking could be repaired, and be inconvenient.

Utility model content

The purpose of this utility model is, there is provided a kind of bottom driving marine propeller, to solve to carry in above-mentioned background technology The problem of going out.The efficiency high and structure of bottom driving marine propeller are concise, when ship needs to turn to, still with strong impetus, Steering procedure is set to become easy and reliable.The bottom driving marine propeller peculiar to vessel that especially shallow water uses.

To achieve the above object, the utility model provides following technical scheme：A kind of bottom driving marine propeller, including master Housing, reduction box, gearbox, power transmission shaft, blade, commutator, the main casing top are fixed with reduction box, gearbox output Driving axis connection power transmission shaft, power transmission shaft is located at main casing bosom position；Main casing bottom connects commutator：The commutation Device is rotating flow guidance cylinder, and for rotating flow guidance jacket casing on power transmission shaft, end part of driving shaft installation blade also in guide shell, is driven shaft end Portion is installed by blade；The barrel of guide shell is provided with flow-guiding mouth, the cylinder end of guide shell and installs shelves with the position of flow-guiding mouth homonymy Plate, plate washer are crescent shape, for blocking the part current of blade；Power transmission shaft blade and guide shell are coaxial, can rotate.Then lead When flow cartridge rotates, the position of its flow-guiding mouth determines the orientation to blade supply fluid, and this orientation relative direction obtains maximum Blade rotary thrust.

The rectangular opening of flow-guiding mouth.The diameter of guide shell is bigger, and the deflecting force of acquisition can be bigger, 360 degree of rotating flow guidance cylinder Rotation, then 360 degree have the divertical motion that deflecting force promotes hull, therefore, any deflecting force for making hull obtain 360 degree.

The 1/8 to 1/2 of a diameter of beam of rotating flow guidance cylinder.

Guide shell and the second output shaft are integrally connected rotation, the second output shaft and the second decelerator by receiving the second input Axle is driven, and second decelerator is that driving gearshaft engages deceleration device or worm and gear speed-reduction apparatus connection；Rotating flow guidance Cylinder makes flow-guiding mouth that guide shell be received into current in a certain position.

Wherein input shaft and the second output shaft is coaxial, and input shaft and the second output shaft drive propeller and guide shell to turn respectively It is dynamic, it does not interfere with each other coaxially.

The end pelvic outlet plane installation catch net of rotating flow guidance wound packages revolving vane；The end of rotating flow guidance wound packages revolving vane Portion's pelvic outlet plane installs parallel deflection fence blade.

Decelerator I and decelerator II forms include but is not limited to The gear deceleration worm gear reducer.

The utility model is also known as bottom driving all-direction propeller, during rotating flow guidance cylinder, the position of its flow-guiding mouth determine to Blade supplies the orientation of fluid, and relative bearing obtains the thrust of maximum, and the diameter of guide shell is bigger, and the deflecting force of acquisition can be got over Greatly, the rotation of 360 degree of rotating flow guidance cylinder, then 360 degree have the divertical motion that deflecting force promotes hull, therefore, can make hull Obtain 360 degree of any deflecting force.

The beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design, is turned to without tail vane, Two-way, three-dimensional or four-way deflecting can be carried out, and there are 360 ° of cornering rates, when not turning normally, flow-guiding mouth is in up or down Position, or a pair of present apparatus are used cooperatively, and a pair of present apparatus flow-guiding mouths are symmetrical, can balance out the deflecting force of turning；Absorbing water Thrust is kept in the case of shallow；It is replaceable blade without dry-docking, it is easy to use；It is compact-sized, it is easily installed and safeguards；It is applicable In a variety of power sources (electronic or internal-combustion engine drives propeller), applicability is wide.Any deflecting force for making hull obtain 360 degree The afterbody of hull is obtained to upper and lower strength, apply and be particularly suitable in shoal.
