Abstract
The utility model relates to a double-hulled ship with a spoiler type stern structure, which comprises a connecting bridge, a left and a right sheet bodies which are connected with the connecting bridge, wherein the left and the right sheet bodies are symmetrical in left and right, and comprise ship bottom boards, shipboard plates and stern closed plates. The different points lie in that spoilers which are projected from the ship bottom boards are arranged on the joints of the stern closed plates and the ship bottom boards of the left sheet body and the right sheet body to form the spoiler type stern structure. The double-hulled ship has the beneficial effects of simple structure and convenient maintenance, changes the fluidized form on the ship bottom through arranging the spoilers on the stern bottom under the conditions of keeping the whole factors and the ship profile unchangeable to regulate the sailing trim angle, makes the ship obtain the excellent sailing trim angle, thereby reducing the residual resistance of the ship, and reaching the drag reduction and energy-saving effects, reduces over 5% the general resistance, or obtaining fast sailing speed under the condition of not changing power.
Description
Technical field
The utility model relates to a kind of catamaran with flow-disturbing type ship stern structure, belongs to the construction of vessel technical field.
Background technology
Wearing wave twin-hull vessel (WPC) is a novel high-performance, the displacement type ship oceangoing ship that develops on the basis of small face catamaran and high-speed catamaran, it is good that it has kept little waterline catamaran rough water quality, and the advantage of conventional high-speed catamaran floor space spaciousness, also merge simultaneously the characteristics of dark V ship type, had rapidity and the rough water quality excellent characteristics of holding concurrently.Your moral number of Design Speed volume Fu of wearing wave twin-hull vessel is generally between 2.0～3.0, in this speed of a ship or plane scope, boats and ships were in the crossing attitude, along with the raising of the speed of a ship or plane, the boat attitude of ship changes, and lifts on the stem, the ship stern sinks, the tangible stern phenomenon of inclining appears in hull, and the residuary resistance of ship is increased, and the power consumption of ship also increases thereupon.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and designs a kind of flow-disturbing type ship stern structure catamaran, make ship obtain preferable running pitch angle, reduce the residuary resistance of ship, reach the purpose that improves the speed of a ship or plane and reduce power consumption.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: comprise connecting bridge 2 and the left and right lamellar body 3 that joins with connecting bridge, described left and right lamellar body left and right sides symmetrical configuration, include bottom plating 4, side plate 5 and stern transom plate 6, its difference is to be provided with the spoiler 7 that is projected on bottom plating at the stern transom plate of left and right lamellar body and bottom plating junction, constitutes flow-disturbing type ship stern structure.
Press such scheme, the left and right lamellar body 3 that described and connecting bridge join is for wearing the left and right lamellar body of wave twin-hull vessel or the Fu Rude number is not less than 2.0 the left and right lamellar body of high-speed catamaran.
Press such scheme, described spoiler 7 is arranged at the junction mutually of bottom plating and stern transom plate, is projected on bottom plating downwards, with the angle α of hull baseline BL be 70 °～90 °; Its height h that is projected on bottom plating comprehensively determines according to principal dimensions, displacement and the speed of a ship or plane of ship, is generally 15～40mm; Spoiler 7 from a left side/right sheet stern larboard is provided with the knuckle line of bottom plating 4 and along intersection line all or part of of stern transom plate 6 with bottom plating 4 to the side plate 5 of starboard; The height that spoiler is projected on bottom plating is contour projection.
Press such scheme, described spoiler 7 can be the fixed type spoiler, and promptly the spoiler one that links to each other with stern transom plate becomes the part of stern transom plate, or takes installation form such as welding, Bolt Connection and stern transom plate to connect firmly together; Or be the adjustable type spoiler, promptly installing reciprocating mechanism at stern transom plate with the bottom plating place of engaging links to each other with spoiler, regulate the height of spoiler projection bottom plating, or by installing rotatable mechaninism with spoiler joins, the rotation angle between adjustment spoiler and the bottom plating.
The beneficial effects of the utility model are simple in structure, maintenance is convenient, in the overall key element that keeps ship under the constant and hull lines unmodified situation, by the fluidised form that spoiler changes the hull bottom current being set in ship stern bottom, make that the distribution of pressure of body changes behind the ship, adjusted running pitch angle, thereby reduced the residuary resistance of ship, reached drag reduction and energy-conservation effect, total drag generally can reduce more than 5%; Or, obtain the higher speed of a ship or plane, thereby improve the mutual coupling of wearing between the overall key element of wave twin-hull vessel in power unmodified situation.For adjustable spoiler, can be implemented under the different speed of a ship or plane states, make ship obtain preferable running pitch angle, reduce the resistance under the different speed of a ship or plane, can realize purpose of energy saving better.
Description of drawings
Fig. 1 is the vertical scheme drawing of ship stern of an embodiment of the utility model.
Fig. 2 is the horizontal scheme drawing of ship stern of an embodiment of the utility model.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
For wearing wave twin-hull vessel, the left and right lamellar body 3 that comprises connecting bridge 2, joins with connecting bridge, the structure left-right symmetric of left and right lamellar body includes bottom plating 4, side plate 5, stern transom plate 6.Also be provided with stem intermediate 1 for wearing wave twin-hull vessel.Spoiler 7 is arranged at bottom plating 4 and stern transom plate 6 junction mutually, and is projected on bottom plating 4 certain altitude h downwards, forms the ship stern of flow-disturbing type.The angle α of spoiler and baseline BL is 90 °, and the height h of its projection bottom plating 4 comprehensively determines h=20～25mm in the present embodiment according to principal dimensions, displacement and the speed of a ship or plane of ship.Spoiler laterally from a left side/right sheet stern larboard is provided with along intersection line whole of stern transom plate 6 with bottom plating 4 to the side plate 5 of the starboard knuckle line with bottom plating 4, the height h of outstanding bottom plating 2 can be contour, also can degree of uprising.Spoiler 7 can be fixed type, promptly is set to one with stern transom plate or takes welding fixing or adopt bolt etc. to install and fix form, and this form only realizes the drag reduction optimum to a certain speed of a ship or plane.Spoiler 4 also can be adjustable, comprises moving up and down to regulate and pass through regulating around the axle rotation, and this adjustable way can realize the best drag-reduction effect under the different speed of a ship or plane states.When ship when navigating by water at a high speed, when hull bottom water wave flows through spoiler, the bottom water flow fluidised form changes, the distribution of body base pressure changes after making ship, adjusted the operational configuration of ship, made running pitch angle be tending towards preferable, thereby reduced residuary resistance, total drag is reduced, and total drag can reduce more than 5%.
Suitable equally for general high-speed catamaran the foregoing description, be that general high-speed catamaran is not established the stem intermediate.
