Description

Super water surface fluid marine propulsion

Technical field

Ship domain, more particularly to a kind of super water surface fluid marine propulsion are the utility model is related to, suitable for shallow water Improve the ship of the super surface propulsion of Shipping tonnage increase in area navigation channel.

Background technology

Recent domestic various countries are in shipbuilding design, due to being subject to coastal port and the shallow limit of cruiseway water System, large ship, particularly 100,000 tons -300,000 ton large-scale large ship ships can not all sail into the harbour unloading, or invest huge amounts of money into Deep water port harbour is built, or needs to lighter transfer by canoe, seriously affects that countries in the world are coastal and inland water transport transport service Development, if investment construction deep water port, cost is big, cycle length, slowly effect.There are 430,000 kilometers of navigation channels in China inland river, because water is shallow, leads to Boat mileage only accounts for 28% or so of national river overall length, and the whole world has several ten million kilometers of shallow draft waterways only to be accounted for because of the shallow cruising range of water 20% or so, to railway construction, highway.Then need to invest huge fund, take a large amount of soils and valuable good farmland again.It is best Method is development of water transport, its small investment, quick, and normal shipboard tail propulsion mode, existing more than 100 history, its maximum Shortcoming in design ship when meeting afterbody propeller, and when optimal drinking water designs, vessel designs drinking water is deeper, and can not meet navigation channel The requirement of traveling.If by vessel designs shallower draft, propeller blade exposes the surface or does not reach optimal propulsion effect at all, then Influence propulsive efficiency and maneuvering performance.For conventional tail tunnel type, the ship of double fiber tip propulsion mode, due to its tunnel design Length is restricted be subject to marine engine position, and afterbody tunnel length is restricted, and especially catamaran-stern hull afterbody causes tunnel vertical profile Line short face is steep, Curvature varying is larger, the current after making propeller work is subject to ponding, and separately accelerate stern propeller Ambient water is disorderly, and when propeller rotating speed improves, tail wake accelerates, and forms vortex wake, propeller works flow field is navigated by water by hull Under the influence of work, it is impossible to meet propeller rotating speed improve situation propulsive force increase therewith.Ship tail propulsion mode over more than 100 years The fluid field of work is limited fluid, it is subject to produce thrust in the fluid wake after ship's navigation all the time.For these reasons, So that the ship tail tunnel type ship that all kinds of routine afterbodys promote fails to obtain in the shallow water cruiseway of shallow water sea area widely Using so that the advantage of Shipping can not be played in shallow draft waterway.

The fairshaped ship of Chinese patent W type tunnel bodies（CN87103815）, the characteristics of patented technology is hull vertical profile Upper thread type is set to W-shaped line style in the range of 1.5 stations to 6 stations at 10 stations in hull overall length（And Dual-closed type twin tunnel can be used）, Propeller is located in the range of tunnel.Its advantage is to significantly improve normal shipboard line style and improve propulsive efficiency, overcomes tail of knowing clearly The shortcomings that tunnel type ship, be primarily adapted for use in the ultra shallow draft vessel of the rapids and shoals in general shallow draft waterway and various rivers.Its shortcoming It is above-mentioned superior performance（Or advantage）Though between showing the station of 1.5 stations -6, the afterbody closing point scale of the W type ships does not have Have it is definite, i.e., hull afterbody closing point scale scale is not provided clearly underwater so that can give ship design and manufacture Into influence.

Chinese patent streamline ship patent No. ZL94112061.9 is to the existing patent of above-mentioned patent Technology is improved further, automatic row's pumping method and/or vacuum suction method and the original for producing vacuum self-priming during using propelled at high velocity Reason, solves the problems, such as that above-mentioned W-shaped line style afterbody closing point scale does not determine, so that it is streamlined to design a kind of vacuum self-priming tunnel body Ship, is allowed to be conducive to the propulsive efficiency for further improving ship, while improves the stability, maneuverability and airworthiness of ship. The drawback is that above-mentioned superior performance（Or advantage）, show that self-priming vacuum suction principle and the station of 0 station -6.5 are designed to be closing Tail tunnel line style point.Tunnel top line I stations in light draft are in below water surface 0.5cm.

The content of the invention

The purpose of this utility model is to be directed to above shortcoming, there is provided a kind of super water surface fluid marine propulsion, Propulsive efficiency is provided.

Scheme is used by the utility model solves technical problem：A kind of super water surface fluid marine propulsion, including More than one propeller, the propeller are arranged in the tunnel body of hull bottom, and the hull overall length is 10 stations, described to push away It is laid in into device at -4.6 station of 4 station of hull；The tunnel body is horizontally arranged at interval along hull bottom；The propeller is one by one Be correspondingly arranged with the tunnel body, 5-8 times of water line when the highest point of the tunnel body exceeds hull clean ship.

Further, 0 station of hull to 7.6 stations are in closed stream line type, and the enclosed point F of 0 station vicinity is located at ship At 1 station location of body, the enclosed point at 7.6 stations is D, and enclosed point F is higher than enclosed point D, and when enclosed point F is located at hull clean ship At least 8cm under water line.

Further, the propeller is screw blade chip propeller or electromagnetic type propeller.

Further, the propeller is screw blade chip propeller, including be arranged in tunnel body screw blade, For driving the transmission shaft and host of screw blade, the host is located in hull cabin.

Further, 5-8 times of the diameter of the screw blade more than hull light draft depth.

Further, the host is located at -5.6 station of 5.3 station of hull, and host is located at 80cm-130cm in ship side It is interior.

Further, paddle lid is changed in the top of the propeller equipped with a vacuum sealing, and the vacuum sealing changes paddle lid and institute State and be tightly connected at the top of propeller.

Compared with prior art, the utility model has following beneficial effect：It is total that the utility model sets various ships its hulls Length is still 10 stations, and for propeller still in the tunnel of hull, feature is from quarter 0 station -7.6 station, is designed to super water surface fluid envelope Tail tunnel line style is closed, quarter enclosed point F on the quarter stands forward near 1 station, and point scale is played in enclosed point F（Or position）Setting Count light draft line（The water surface）At least 8cm below, marine transportation ship are 18cm, and the line style in F points position is again attached higher than 7.6 stations The line style of near enclosed point D points（How much be higher by should be depending on clean ship designs optimum propeller diameter）, it is ensured that stern is all vertical Afterbody is not easy to can guarantee that the smooth in water flow into propeller again into air when being navigated by water in transverse wave, and discharge is smooth.In addition, also at the same time It is required that hull both sides should be in same level with hull bottom baseline, it is most that propeller, which is located at 4-4.6 stations that hull overall length is 10 stations, Good propeller work is smooth.
