Abstract

The invention relates to a high-speed boat. The high-speed boat comprises a boat body and more than three power devices mounted inside or outside the boat body; each power device is used for driving a propeller. The boat body comprises a deck, a base plate and a stern transom plate; the stern transom plate is formed by use of folding plates which are symmetrical on the left and right sides about the longitudinal section; the folding plates are formed by corresponding fold lines vertically drawn between the base plate and the deck; at least one concave region facing the bow is formed on the stern part of the boat body; at least one propeller is arranged in each concave region. Under the design requirement of the same driving power configuration, the high-speed boat is capable of obtaining a higher speed.

Description

High-speed boat

Technical field

The present invention relates to and the closely-related ship stern of naval hydrodynamics feature improved shape, specifically, relate to a kind of high-speed boat that improves stern structure.

Background technology

Existing ship is when stern designs, low powered adopts the structure design of camber stern, high-speed boat adopts the structure design of the flat pattern stern showing as Fig. 1, flat pattern stern refers to that stern transom plate is to be formed along vertical stretching by a straight basic from base plate to main deck, be that stern transom plate can be vertical with the water surface, also can form a little angle with the water surface.

In ship design, fixedly under displacement situation, speed of a ship or plane aspect ratio common and engine installation and hull is closely related, high-speed boat is especially true, referring to Fig. 2, its engine installation adopts inboard hanging outdoor unit or outboard drive set more, for reaching Design Speed, often adopts engine installation as much as possible and is arranged on flat pattern stern by word order.Thus, produced under the little situation in hull space, can not reduce aspect ratio again because aspect ratio reduce will make the wave making resistance significantly increase.Another problem that the design of Fig. 2 exists is because engine installation transverse pitch is when too small, will cause that difficulty is installed and maintenance is inconvenient, and mutual interference during manipulation.For overcoming the problems referred to above, in prior art just like the engine installation arrangement of Fig. 3, it adopts three high-power main frames to be arranged in main engine room by Chinese character pin-shaped, but the long stern tube shaft of its relative complex makes shafting structure complicated design, is only suitable for adopting in the boats and ships of large displacement.Fig. 4 is the plant layout of a high-speed patrol boat, and its four outboard drive sets force that ship is wide reaches 4.2 meters, so design, under the certain situation of displacement, wave making resistance increases suddenly, and this ship has exchanged the small size raising of the speed of a ship or plane for to have dropped into huge power, very uneconomical.

Summary of the invention

Main purpose of the present invention is to provide a kind of high-speed boat with more reasonable stern shape design.

In order to realize above-mentioned main purpose, high-speed boat provided by the invention, comprises hull and is arranged on three inner or outer above engine installations of hull, every engine installation drives a screw propeller.Hull comprises deck, base plate and stern transom plate, stern transom plate forms by closing the symmetrical flap of center buttock, flap is formed from base plate to vertical stretching between deck by corresponding broken line, makes the stern of hull form at least one Xiang Shouao district, is at least provided with a screw propeller in each recessed district.

From above scheme, the present invention changes the structure design of traditional flat pattern stern, on the basis of flat pattern stern, designed at least one the recessed district to bow, a screw propeller is at least set in each recessed district, three above engine installations are staggeredly arranged on ship is longitudinal, not only make the transverse pitch of engine installation can greatly dwindle under non-interference situation, also make can obtain large as far as possible aspect ratio under same displacement situation, reduce wave making resistance, thereby under the situation of same engine installation, obtain higher ship speed.

A concrete scheme Shi Ao district is set to one, is positioned at the middle part on stern Width.

Another concrete scheme Shi Ao district is set to two, is positioned at two sides of a ship of stern.

Scheme is that engine installation is outboard drive set more specifically.

Another more specifically scheme be that engine installation is the inside and outside machine of the side of a ship.

In above-mentioned each scheme, can also make deck cover recessed district.So, can on relatively little high-speed boat, obtain large as far as possible floor space.

Below in conjunction with drawings and Examples, the invention will be further described.

The specific embodiment

The first embodiment

Referring to Fig. 5, the stern transom plate 1 of high-speed boat stern has formed one at center line to be run through between deck and base plate, is arranged on Liao Ao district 4 to one in 4, three, district of the recessed Ao of bow outboard drive set 2, thereby makes the screw propeller 3 ' of its driving be positioned at recessed district 4.

The second embodiment

Referring to Fig. 6, the stern transom plate 1 of high-speed boat stern has formed one at center line to be run through between deck and base plate, is arranged on Liao Ao district 4 to one in the inside and outside machine 2 ' of 4, three, district of the recessed Ao of the bow side of a ship, thereby makes the propeller 3 ' of its driving be positioned at recessed district 4.11 meters of the length of this high-speed boat, wide 2.9 meters, hull adopts aluminum alloy, and three inside and outside machines 2 ' of the side of a ship make this high-speed boat reach the speed of a ship or plane of 58 joints.

The 3rd embodiment

Referring to Fig. 7, the stern transom plate 1 of high-speed boat stern has respectively formed one at left and right two sides of a ship to be run through between deck and base plate, be arranged on Liao Ao district 4 to two in the inside and outside machine 2 ' of 4, three, district of the recessed Ao of the bow side of a ship, thereby make the screw propeller 3 ' of its driving be positioned at recessed district 4.

The 4th embodiment

Referring to Fig. 8, the stern transom plate 1 of high-speed boat stern has formed one at center line to be run through between deck and base plate, is arranged on Liao Ao district 4 to two in 4, four, district of the recessed Ao of bow outboard drive set 2, thereby makes its separately-driven two screw propellers 3 ' be positioned at recessed district 4.

The contrast of the existing design high-speed boat showing as this example and Fig. 4, same displacement, under the situation of same model outboard drive set, the wide B2 of this routine ship is 3.5 meters, it is 4.2 meters that the high-speed boat that Fig. 4 shows must reach the wide B1 of ship, as can be seen here, this example can design greatlyr by aspect ratio, obtains the higher speed of a ship or plane.

Other embodiment

Referring to Fig. 9, Figure 10, for first and second embodiment, recessed district 4 is through deck 5 and base plate 6, the advantage that such design has be to the maintenance of engine installation and screw propeller more for convenience.

Referring to Figure 11, Figure 12, some high-speed boat for there being large as far as possible floor space requirement, can improve the various embodiments described above, deck is extended relatively cover stern Ao district 4 exactly, makes deck level continuously and makes stern structure intensity higher.This design brings recessed district internally-powered device and screw propeller to safeguard inconvenient defect, can offer the modes such as manhole cover by deck, Ao district and be overcome.
