Description
The utility model relates to a kind of water-jet propeler for ship.
Existing marine propulsion device is the propeller type propelling unit.During this ship navigation, stem punching press fwd water body, the speed of a ship or plane is high more, and suffered wave making resistance is also just big more, the screw propeller high-speed operation of afterbody simultaneously, suffered eddy resistance is also just big more.Propeller type advances the naval vessel being absorbed on the speed-raising problem among the self-contradictory predicament, because raising along with route speed, wave making resistance and eddy resistance can increase exponentially, for the propulsive force that improves route speed and increase a large amount of consumption of having to overcoming aspect the resistance that is multiplied, thereby the effort of ship ship speed-raising is produced little effect.
Order of the present utility model is to overcome above-mentioned weak point, and a kind of water-jet propeler for ship is provided.
The purpose of this utility model is achieved in that water-jet propeler for ship includes water absorber, water delivery device, water injecting system.Water absorber is positioned at the stem on naval vessel, contain water sucking mouth, water sucking mouth protection net, valve, the water sucking mouth is opened in the stem on naval vessel, the water sucking mouth protection net covers the opening portion of water sucking mouth, be connected on the housing on naval vessel, the water inlet end of valve is in the cavity of water sucking mouth, and the front end of the water-supply-pipe in its water side and the water delivery device links.Water delivery device is positioned at the middle part on naval vessel, contains water-supply-pipe, boost pump, supercharging water-supply-pipe, and they link successively, and the rear end of water-supply-pipe and the water inlet end of boost pump link, and the front end of the water side of boost pump and supercharging water-supply-pipe links.It is a plurality of that boost pump in the water delivery device can be a formula, looks the needs of length, size and the supercharging on naval vessel, if a plurality of, then from first order one-level coupled in series (boost pump then is the one-level supercharging, and a plurality of boost pumps are multistage supercharging) successively to the end.Water injecting system is positioned at the afterbody on naval vessel, contain sprinkler, nozzle switch, movable shower nozzle, movable shower nozzle effector, the water side of the water inlet end of sprinkler and supercharging water-supply-pipe links, the water inlet end of its water side and nozzle switch links, the water side of nozzle switch and the water inlet end of movable shower nozzle link, the housing of naval vessel afterbody is stretched out in the water side of movable shower nozzle, water outlet is spurted in the water body on carrying naval vessel, movable shower nozzle effector is installed in the afterbody on naval vessel, but the manipulation activities shower nozzle changes water spraying direction (angle).Water absorber in the water jet propelling unit, water delivery device, water injecting system connect on the bottom surface that is installed in ship shell successively.As required, can there be one or more sets water jet propelling units on a naval vessel.Valve in the water absorber contains valve body, flap, gear, axle and power, and gear is coaxial with flap, and power makes flap rotary opening closing valve by Transmission.Boost pump contains the pump housing, impeller, axle and power, and impeller is contained on the axle, and axle links with power.Sprinkler contains casing, injection axis and power, and injection axis is contained in the casing and with power and links.Movable shower nozzle effector is installed in the naval vessel afterbody, contain control box, hauling rope, dish body, the dish body is made of video disc, latch closure is arranged on the video disc, the video disc superposition, sheet sheet button mutually is linked into the dish body, the dish body tightly is sleeved on the jet pipe of movable shower nozzle, is the metal filament flexible pipe on the jet pipe, stretches out outside the ship shell, the two ends of hauling rope, one end and dish body link, and an end and control box link, dynamic and transmission device in the control box, can handle the hauling rope motion, thereby hauling rope affects the dish body to make jet pipe upper and lower, left and right deflection reach the purpose that changes water spraying direction (angle).
Advantage of the present utility model is novel ingenious, because the change of propulsion mode: the brand-new propulsion mode that stem initiatively absorbs water, middle part supercharging water delivery, afterbody are sprayed water at a high speed, wave making resistance and eddy resistance in the time of can reducing ship navigation in a large number, improve the effect of naval vessel propulsion system greatly, thereby the solution of a naval vessel speed-raising difficult problem is looked for another way.Because the propeller type propulsion mode is absorbed on the speed-raising problem in the contradiction that is difficult to more more, route speed is high more, and wave making resistance and eddy resistance are just big more, and a large amount of consumption of the propulsive force of increase overcoming on wave making resistance and the eddy resistance, so speed-raising is solid difficult, the speed of a ship or plane is limited.The present invention is owing to adopt the stem suction, middle part supercharging water delivery, the propulsion mode that afterbody is sprayed water at a high speed, not only can reduce wave making resistance and eddy resistance in a large number, but also can increase suction thrust power and pressure reduction thrust power, the navigation speed-raising on naval vessel is in the benign cycle, can obtains at a high speed, energy-conservation, flexible, stable navigation performance opened up wide future for navigation at a high speed.
