Abstract
The utility model discloses a high efficiency front mounted type bidirectional ship, which includes a ship body, a promoting propeller, and a propeller rudder, wherein the promoting propeller is mounted at the rear part of the ship body, two propeller rudders are respectively arranged at both sides in the position between the eighth station and the tenth station calculated from the stern to the bow, where is in range from the keel line to 1/2 distance between the keel line and the water line. The use of the utility model eliminates the hindering effect of the rudder to the promoting propeller, and realizes more convenient ship turning and more flexible control, and the two propeller rudders at the bow allows the ship more balanced during sailing.
Description
Technical field
The utility model relates to the two-way boats and ships of a kind of efficient forward type.
Background technology
At present, the rudder of all boats and ships all is located at the back of the screw propeller of stern, this traditional back rudder, when ship turns round when travelling, its rudder must be swung and have a certain degree, and causes the current of two strands of different pressures, this differential pressure action allows rudder generating effect power on the rudder face of rudder both sides.The higher current of pressure are inclined to preceding one side slightly at rudder, the appearance that allows rudder fling forward of seeming to resolutely refuse, and rudder seems and dare not fling, stubborn partially gradually to pressure low beyond.This resistance to water-flow, it is apparent to the influence of the speed of a ship or plane of ship.But rudder causes the current pressure differential simultaneously, and also the companion comes the current vortex, forms the whirlpool resistance, also is the speed of a ship or plane that has influence on ship finally.The angle of rudder swing is big more, and these two kinds of resistances are big more, and the suffered influence of the speed of a ship or plane of ship is also just big more.In general, ship is in navigation, even if straight-line travelling.Rudder also is the frequent left and right swing that do not stop.Its reason is the influence that ship itself is subjected to current and wind direction on the sea.Therefore we can say that the speed of a ship or plane of ship does not stop is subjected to the resistance to water-flow that rudder causes and the influence of whirlpool resistance, has finally consumed marine engine power.
Summary of the invention
The purpose of this utility model is to provide a kind of resistance that can reduce propelling screws, turns to conveniently, is the two-way boats and ships of efficient forward type of living.
For achieving the above object, the two-way boats and ships of a kind of efficient forward type of the present utility model, comprise hull, propelling screws, propeller rudder, propelling screws is located at the afterbody of hull, between No. eight of being located at respectively that hull with ten stations calculates from the stern-on fore of two propeller rudders and No. nine station and keel line extremely with the dual-side of the ship of 1/2 position range of keel line and floating line distance on.
After adopting such structure,, eliminated the inhibition of rudder, brought more convenient, the flexible control of turning to of boats and ships, and two propeller rudders on the fore can make boats and ships in navigation process balance more propelling screws because rudder is arranged on boats and ships the place ahead.
Description of drawings
Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model,
Fig. 2 is the A-A cutaway view of Fig. 1.
Specific embodiments
The two-way boats and ships of of the present utility model a kind of efficient forward type shown in Fig. 1-2, comprise hull 1, propelling screws 2, propeller rudder 3, propelling screws 2 is located at the afterbody of hull 1, it is characterized in that: No. nine of being located at respectively that hull 1 with ten stations calculates from the stern-on fore of two propeller rudders 3 go up and keel line to the dual-side of the ship of 1/2 position range of keel line and floating line distance on.During use, the engine installation that directly drives propeller rudder 3 can be oil motor, electric notor, mechanically operated mode, if adopt oil motor 4, then oil motor 4 direct mounts is fixed in the ship storehouse, and propeller rudder 3 is connected with the output shaft of oil motor 4.Its principle of work is: one side when boats and ships when turning, this ship driving engine drives high-pressure oil pump, at this moment, the hydraulic oil that pressure is high, through high pressure fuel pipe and governor, oil motor 4 is given in transmission, so driven propeller rudder 3 rotations of opposite side, fore moved to this side.Realize that boats and ships are to turning on one side.Turn to another side when needs, make oil motor drive opposite side and rotate to propeller rudder 3, fore is moved to another side, the realization boats and ships are turned to another side.Eliminated the inhibition of rudder thereby reached, brought more convenient, the flexible control of turning to of boats and ships, improved the route speed of boats and ships propelling screws.
