Description
Technical field
The present invention relates to a kind of water-jet propeler for ship.
Background technology
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 the raising route speed increases has to consume in a large number overcoming on the resistance that is multiplied.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, and a kind of water-jet propeler for ship is provided.
The object of the present invention is achieved like this: 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, water sucking mouth switch, 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 water sucking mouth switch connects the closing in end 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.Boost pump in the water delivery device can be one or more, look the naval vessel length, size and supercharging need configuration, if a plurality of, then from first order one-level coupled in series (boost pump is the one-level supercharging, and a plurality of boost pumps then are multistage supercharging) successively to the end.Water injecting system is positioned at the afterbody on naval vessel, contain sprinkler, the tuning valve, forward shower nozzle and switch, reverse shower nozzle and switch, 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 tuning valve links, two water sides of tuning valve link with the water inlet end of forward nozzle switch and the water inlet end of reverse nozzle switch respectively, afterbody front, naval vessel housing is stretched out in the water side of forward shower nozzle, its water outlet is spurted in the back water body on carrying naval vessel, naval vessel afterbody side housing is stretched out in the water side of reverse shower nozzle, and its water outlet is spurted in the side water body on carrying naval vessel.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.The water sucking mouth flare, the housing of open end and naval vessel stem links, and utilizes that naval vessel stem housing is bent to become semi-open catchment recess, and the groove upstream face has protection net, and the closing in end of water sucking mouth is positioned at ship shell, links with the water inlet end of water sucking mouth switch.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.The tuning valve contains valve body, valve shaft, water inlet end, forward water side, side direction water side, base, flap tightly is enclosed within the valve body, rotate change water outlet direction by valve shaft, when closing the side direction water side, open the forward water side, or in the water side, close the forward water side in open side, make from the High-Pressure Water of sprinkler or from the ejection of forward shower nozzle, or from reverse shower nozzle ejection, thereby make the naval vessel or advance or turn to or fall back, reach the tuning purpose.Because the tuning valve has convenient and flexible tuning function, can make water jet naval vessel realize no rudder manipulation.Water sucking mouth switch and nozzle switch (comprising forward nozzle switch and reverse nozzle switch) are the through type switch, because of security consideration is provided with.In a single day these switches cut out, and can stop extraneous water body to enter water-jet propeler for ship, help the maintenance at any time of equipment.
The invention has the advantages that 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 in the contradiction that is difficult to go beyond on the speed-raising problem, 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 the speed-raising difficulty, the speed of a ship or plane is limited.The present invention is owing to adopt stem initiatively to absorb water, 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, provide a brand new propulsion mode for the naval vessel navigates by water at a high speed.
