Abstract
A water-jetting high-speed ship features that a high-power axial flow pump is used as water-jetting propeller to increase propelling efficiency and a great-diameter through pipe is used as internal by-pass unit to decrease inertial resistance. Its advantages are high speed (200-300 Km/h) and saving energy by 40%.
Description
The present invention relates to the agent structure and the propulsion mode of steamer.
The agent structure of existing steamer is a highly faired hull, and propulsion mode is that screw propeller advances.Its advantage is that available space is big in the cabin, builds and use more convenient.Weak point is that route speed is too low, and general speed per hour is all below 100 kilometers, and the modern society of this and high speed development is incompatible with, is very big obstacles for the abundant development and utilization marine resources of the mankind.The automobile of land, train are all in the speed of clearing of obstruction raising by fair means or foul, and the good place that open without hindrance steamer just runs riot in the ocean be as the saying goes: " sky appoints bird to fly, and Hai Kuo is with fish dive ".Therefore, improve steamer speed significantly and become pressing for of modern social development.
The purpose of this invention is to provide a kind of operation at a high speed and reposefully, again than the existing more energy-conservation novel steamer of steamer.
In the guiding theory of existing construction steamer, have two theories to have serious problems: the one, think that the drag characteristic of water is a friction drag; The 2nd, think that antagonistic force and application force equate.In-depth study through us is found: though the drag characteristic of water has the friction drag feature aspect acting, but have the inertia resistance feature aspect resistance big or small, should use formula F
Resistance=ma (m: the quality of the water that expression takes exercises, a: the acceleration/accel that produces during the motion of expression water) calculate; Though the size of antagonistic force is closely related with application force, the two is not all equal fully under any condition, generally is F
Instead=F
Resistance≤-F.F
Resistance=ma shows that the resistance of water increases rapidly along with the rising of ship's speed, if with this formula air resistance and comparison of water resistance masterpiece, just find that object suffered water resistance under identical kinematic velocity approximately is 800 times of air resistance, the reason that water resistance that Here it is is difficult to overcome.F
Instead=F
Resistance≤-F shows longitudinal resistance suffered when thrust that steamer obtains equals the screw propeller rotation, and it is general all less than application force that driving engine provided, the big more propulsion coefficient of radius that is to say screw propeller is just high more, the existing low reason of Screw Steamer propulsion coefficient that Here it is.
Comprehensive above-mentioned two theories, in order to obtain thrust effectively and to reduce advance resistance, the present invention has done the improvement of two aspects to prior art: the one, adopt high-performance axial-flow pump as pump jet so that obtain antagonistic force effectively; The 2nd, adopt bigbore water pipeline from the cabin internal shunt, be used for reducing to make the huge inertia resistance of water generates because of the steamer high-speed motion.Concrete scheme is: both sides on the bow respectively are provided with a water inlet, are provided with the water injector that Y font drain hose connects these two water inlets and stern belowdecks; Be provided with power machines such as driving engine, power-transfer clutch and change speed gear box between preceding two arms of Y font drain hose, the impeller in Y font drain hose and pipe constitutes a high-power axial flow pump, as the pump jet of steamer; The both sides of Y font drain hose respectively be provided with heavy caliber that front and back communicate cross water pipe as the cabin in diverter, be used for the resistance that increases the wheel beam and reduce to advance.
Utilize 2 improvement of the present invention, can constitute various embodiments such as single propelling unit and a plurality of propelling units.
The drawing explanation:
Fig. 1 is a cabin inner structure scheme drawing of the present invention,
Below in conjunction with the embodiment (accompanying drawing) that single propelling unit constitutes, the invention will be further described.
Basic profile of the present invention still is a stream line pattern.With reference to shown in Figure 1, both sides on the bow respectively are provided with a water inlet 1, are provided with the water injector 5 that Y font drain hose 4 connects these two water inlets 1 and stern belowdecks; Be provided with power machines such as driving engine 6, power-transfer clutch 7 and change speed gear box 8 between preceding two arms of Y font drain hose 4, the impeller 9 in Y font drain hose 4 and pipe constitutes a high-power axial flow pump, as the pump jet of steamer; Be provided with tail vane 10 in the centre of water injector 5, in order to the navigation direction of control steamer.The both sides of Y font drain hose 4 respectively be provided with heavy caliber that front and back communicate cross water pipe 3 as the cabin in diverter, be used for the resistance that increases the wheel beam and reduce to advance; Water inlet 1 at Y font drain hose 4 locates also to be provided with aperture plate for 2 liang with the water inlet of crossing water pipe 3, in order to prevent that bigger solid body from entering pipeline and causing obstruction.
Tool following features of the present invention:
1. the little propulsive efficiency height of the running resistance of water jetting ship is with existing Steamer is compared can energy-conservation 35-45%, can also improve speed 2-3 simultaneously doubly And even higher; 2. the propeller of water jetting ship can arbitrarily increase, its Ship Structure just can suitably be widened, thereby has shallow draft and wind and wave resistance energy The advantages such as power is strong; 3. compare with existing catamaran, high-speed and energy-saving not only, But also has the advantage such as the strong and good stability of cargo capacity.
Claims (3)
1. a water-jetting high-speed ship is characterized in that: be provided with high-power axial flow pump as pump jet on hull, improve propulsion coefficient so that obtain antagonistic force effectively; The heavy caliber water pipeline that communicates before and after being provided with belowdecks is used for reducing to make because of the steamer high-speed motion the huge inertia resistance of water generates as the internal shunt device.
2. be on hull, to be provided with high-power axial flow pump in feature of the present invention aspect the propelling unit as pump jet.
3. feature of the present invention is that the heavy caliber water pipeline that communicates before and after being provided with belowdecks is as the internal shunt device aspect hull structure.
