Abstract

The invention discloses a wave-penetrating high-speed catamaran passenger ship. The wave-penetrating high-speed catamaran passenger ship consists of an upper ship body, two lower submerged bodies and two sheet bodies, wherein the lower submerged bodies are deeply arranged underwater, and the sheet bodies are used for connecting the upper ship body with the lower submerged bodies. The wave-penetrating high-speed catamaran passenger ship disclosed by the invention has excellent wave-resisting performance and self-stability and the capabilities of keeping stable and comfortable during high-speed travelling and withstanding greater wind and waves, and has the advantages of excellent controllability, large loadage and good economic performance.

Description

Wear unrestrained high speed binary passenger boat

Technical field

The present invention relates to a kind of catamaran, particularly a kind ofly wear unrestrained high speed binary passenger boat.

Background technology

As its name suggests, we generally call catamaran laterally connect firmly the ship that constitutes by two single hulls together.The mankind use catamaran to be owing to find two ships are laterally linked together the earliest; Can be from the inland river to the maritime navigation and be not easy shipwreck; Once this method was used on the sailing boat in early days, and had built sailcatamaran, this sailing boat can bear bigger stormy waves at sea.On this basis, people find that again catamaran compares with the single hull of same tonnage, have bigger floor space and volume of compartment, therefore are used to freighter.After the sixties in 20th century; Along with developing rapidly of marine high speed passenger transportation; High-speed catamaran is owing to have roomy floor space, space and be convenient to luxurious decoration and good by generally, become with fastest developing speed in the high performance craft in recent decades, use the widest, build maximum a kind of of quantity.

The representative type high-speed catamaran is made up of two tall and thin single hulls (being called lamellar body), and top connects with the deck bridging, and equipment such as engine installation, power station are set in the body, and superstructure is settled on bridge top, deck, in establish main cabin, living facilities etc.High-speed catamaran makes each lamellar body taller and thinner, thereby has reduced wave making resistance owing to be divided into two lamellar bodies to single hull, makes it have the higher speed of a ship or plane, and its speed of a ship or plane generally reaches the 35-40 joint at present; Because the binary beam is more much bigger than single hull, its stability obviously is superior to single hull, and has the ability of bearing than high sea; Catamaran not only has good road-holding property, but also has characteristics such as drag hump is not obvious, carrying capacity is big, thereby is widely used in dual-use boats and ships by countries in the world.

Summary of the invention

The object of the invention can bear the ability than high sea in order to provide a kind of also can held stationary when running at high speed comfortable, has good road-holding property, and carrying capacity is big, good economy performance wear unrestrained high speed binary passenger boat.

The object of the invention can be realized through following scheme.

The present invention wears unrestrained high speed binary passenger boat and is connected upper hull with two, is descended lamellar body three parts of submerged body to form by upper hull, two dark following submerged bodies of putting under water.Streamlined body is made in the lamellar body outside, and the linear pattern body is made in the inboard; Lamellar body outside bow and the special taper of stern, shape adopts slightly concave or linear.

The bench section of lamellar body is V-shape or dark V-shape.

Upper hull between two lamellar bodies is provided with at least one waterjet propulsor.

The invention has the beneficial effects as follows: the present invention provides a kind of have good rough water quality and self-stability; Also can held stationary when running at high speed comfortable, can bear ability than high sea, have good road-holding property; Carrying capacity is big, good economy performance wear unrestrained high speed binary passenger boat.

The specific embodiment

Below, through accompanying drawing and exemplary embodiment the present invention is specifically described.Yet, should be appreciated that under the situation that does not have further narration, element, structure and the characteristic described in one embodiment also can be attached among other embodiment valuably.

As shown in Figure 1, the present invention wear unrestrained high speed binary passenger boat by upper hull 1, two dark following submerged bodies of putting under water 4 be connected upper hull 1 with two, lamellar body 3 three parts of submerged body 4 are formed down.Upper hull 1 can be provided with various main cabins and living quarter, is used for supplying guest's rest of living.Present embodiment will with waterjet propulsor 2 the catamaran stern be example present invention is described, yet not should be understood to be limitation of the present invention for this.

As shown in Figure 2, streamlined body is made in lamellar body 3 outsides, and the linear pattern body is made in the inboard; Lamellar body 3 outside bows and the special taper of stern, shape adopts slightly concave or linear.

During ship running, the special taper of lamellar body 3 outside bows can reduce wave making resistance, and the speed of a ship or plane is comparatively favourable for improving; The stern shape is considered from resistance and propelling aspect, separates for avoiding current, reduces the whirlpool resistance, improves angle of rake service conditions, and cut-off line or nick are advisable.The linear pattern body is made in lamellar body 3 inboards, and the current that lamellar body 3 inboards are flow through are comparatively steady, and the wave that causes is also little, and the wave phase mutual interference that lamellar body is 3 is little, has also reduced the influent stream angle of lamellar body 3 leading portions simultaneously greatly, and this is all greatly favourable to improving ship speed.In addition, lamellar body 3 inboards are linear pattern, can be very favourable with raising waterjet propulsor 2 work efficiencys to the working condition of improving waterjet propulsor 2.

As shown in Figure 3, the bench section of lamellar body 3 is V-shape or dark V-shape.The V-shape section is favourable for the resistance of reducing friction, and concerning the stern shape, the V-type section makes the after run current smooth and easy, can reduce and execute vortex drag; In addition, the V-type section is favourable to rough water quality, and pitching, the damping of swinging of hanging down increase, and amplitude reduces.

Upper hull 1 between two lamellar bodies 3 is provided with at least one waterjet propulsor 2, is used for propulsion of ship.Wear unrestrained high speed binary passenger boat and use two tall and thin following submerged bodies 4; Utilize the mode of waterjet propulsor 2 with jet water course, push water to ship fast after, according to Newton's third law; Can obtain huge forward propulsion (antagonistic force); Quicker than adopting common screw propeller to promote, and when high speed, the resistance of tall and thin hull more can significantly reduce.Waterjet propulsion is normally sucked water by boost pump from carrier base, spray at the back through water injector at high speed current direction carrier, and the thrust that utilization is effluented and the influent stream momentum change produces promotes carrier and advances.

Lamellar body 3 all will be noted the smooth-going transition of bonded assembly with upper hull 1, lamellar body 3 with the connecting bridge of following submerged body 4, to avoid connecting bridge generation serious stress concentration.

Should be pointed out that above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.Under the prerequisite that does not break away from spirit and scope of the invention; Those of ordinary skill in the art obviously can make various corresponding changes and distortion to the present invention, but these changes and distortion all should belong in the scope that accompanying claims of the present invention and equivalent thereof protect.
