Description
Technical field
The invention belongs to ship machinery technical field, is related to a kind of trimaran.
Background technology
Trimaran is mainly made up of three hulls, is among it hull, and respectively there is a size identical auxiliary both sides shoulder to shoulder
Hull, three hulls share a main deck and superstructure, and using turbine hydro-motor, anti-make is obtained by spraying water backward
Firmly push ahead.Because the design of each hull hull is long and narrow, there is less designed waterplane, length-width ratio is big, so as to
The wave making resistance of ship is reduced, reduces drag overall.
The U of China patent CN 204250295 disclose a kind of folding trimaran lateral piece.It is by lamellar body, connecting rod
1st, connecting rod 2, connecting rod 3, connecting rod 4, revolute pair 1, revolute pair 2, revolute pair 3, revolute pair 4 are formed；Lamellar body is hollow, outward appearance
Streamlined, its cross-sectional profiles is in " deep V-arrangement "；Connecting rod 1, connecting rod 2 are close to ship's head；Revolute pair 1, revolute pair 2, turn
Built-in self-locking device in dynamic pair 3, revolute pair 4, connecting rod can be locked in the shape after connection is remembered and turns to required angle
State.By the telescopic folding of 4 connecting rods, folding trimaran lateral piece can realize three kinds of working conditions：Extended configuration, receipts
Contracting state and " V " font state.When ship, which runs into emergency, to be needed quick deceleration or pull in shore to berth, trimaran lateral piece
Just show " V " font state, in this operating condition, the lamellar bodies of main hull both sides by current impulsive force so that
Ship resistance increases, and contributes to ship quick deceleration, reduces inertial stopping distance.
But above-mentioned trimaran still has certain shortcoming：1st, the demand that trimaran occurs is, three hulls share one
Deck, naval vessel space is improved, meets the requirement to naval vessel such as helicopter.And three hulls in above-mentioned patent do not share one
Individual deck, do not see that three hulls have any effect；2nd, above-mentioned trimaran is when needing to slow down, in " V-shaped ", the work of wave
The tip of V words is firmly concentrated on, and folding structure is inherently more thin, therefore be more easily broken off, practical performance
It is bad, do not have good slowing effect.
The content of the invention
The purpose of the present invention is to be directed to above mentioned problem existing for existing technology, it is proposed that a kind of trimaran, institute of the present invention
Technical problems to be solved are：How the slowing effect of this trimaran is improved.
The purpose of the present invention can be realized by following technical proposal：
A kind of trimaran, the trimaran include main hull and the auxiliary hull positioned at main hull both sides, the main hull
On be provided with deck, the auxiliary hull is connected with the both sides on deck, it is characterised in that if the auxiliary hull is provided with dry plate water
Flat board, short transverse of each level board along auxiliary hull are distributed and are slideably positioned on auxiliary hull, and energy is provided with the auxiliary hull
The driving source for enough driving level board to be moved along auxiliary hull height direction.
Its operation principle is as follows：In normal exercise, each level board has larger this trimaran away from sea, auxiliary hull
Length-width ratio, both meet the needs of big deck, again reduce ship wave making resistance, reduce drag overall, ensure trimaran normally make
With.And when needing to be slowed down, level board can be moved to by the position being in contact with sea by driving source, it is auxiliary so as to reduce
The length-width ratio of hull, increase drag overall, realize quick deceleration.The program compared with the documents referred in background technology,
Both the advantages of normally having realized trimaran, while in assisted deceleration, the principle for changing length-width ratio is efficiently utilized, effect of slowing down
Fruit is good, and will not produce the situation of stress concentration, reduces part and is damaged probability.
In a kind of above-mentioned trimaran, the auxiliary hull is provided with three one slide rails, the level board along its short transverse
It is divided into level board and lower horizontal board, the upper level board and lower horizontal board are slidably connected with three slide rails.It is designed with
After upper level board and lower horizontal board, operator can select corresponding level board to be in contact with sea according to being actually needed, so as to change
Become corresponding length-width ratio.
In a kind of above-mentioned trimaran, the lower horizontal board is slidably connected on the slide rail by sliding block, it is described on
Level board is located at the surface of the lower horizontal board, and is slidably connected by slide bar and the slide rail, the lower horizontal board it is upper
Plate face offers the neck corresponding with the slide bar, the length and width all same of the upper level board and lower horizontal board.
It when being slowed down, such as only need to increase less resistance, then can only drive lower horizontal board movement to be contacted with sea by driving source
, now length-width ratio suitably reduce；And when needing quick deceleration, when increasing more resistance, then it can be driven by driving source
Upper level board moves down, and after the slide bar on upper level board is in contact with the neck on lower horizontal board, can continue to drive lower level
Plate moves down, until upper level board and lower horizontal board are in contact with sea, now the length-width ratio of auxiliary hull then significantly subtracts
It is small, quick deceleration can be achieved；The design plate above the average is consistent with the length and width of lower horizontal board, can reduce die sinking production cost,
And convenience during maintenance.
In a kind of above-mentioned trimaran, the driving source includes the cylinder one and cylinder two vertically set, institute
The cylinder body for stating cylinder one and cylinder two is both secured to the lower face on the deck, the piston rod of the cylinder one can with it is described under
The upper face of level board abuts against, and the piston rod of the cylinder two can abut against with the slide bar on the upper level board；It is described
Upper level board and lower horizontal board are also connected by extension spring with the lower face on the deck respectively.When only need lower horizontal board with sea
When face is in contact, it can be extended by the piston rod of cylinder one, promote lower horizontal board to decline until being in contact with sea；When cylinder two
When being extended with piston rod, after piston rod is in contact with slide bar, level board can be driven to decline, treat slide bar on lower horizontal board
In neck, lower horizontal board is driven to decline together until being in contact with sea, and then change length-width ratio；Wait after slowing down, cylinder
One and cylinder two piston rod withdraw, lower horizontal board and upper level board can reset in the presence of extension spring.
In a kind of above-mentioned trimaran, the lower face on the deck is vertically and fixedly provided with some guide rods, the upper level
The through hole corresponding with the guide rod is offered on plate and lower horizontal board, is provided with what is be engaged with the guide rod on the through hole
Guide pin bushing.After being designed with guide rod and guide pin bushing, flexible to the piston rod of cylinder one and cylinder two position-limiting action can be played, improve motion essence
Degree.
Compared with prior art, the present invention has advantages below：
In normal exercise, each level board has larger length-width ratio, both met this trimaran away from sea, auxiliary hull
The demand on big deck, reduces the wave making resistance of ship, reduces drag overall again, ensures trimaran normal use.And working as needs to carry out
During deceleration, level board can be moved to by the position being in contact with sea by driving source, so as to reduce the length-width ratio of auxiliary hull, increased
Big drag overall, realizes quick deceleration.The program both normally realizes three bodies compared with the documents referred in background technology
The advantages of ship, while in assisted deceleration, the principle for changing length-width ratio is efficiently utilized, slowing effect is good, and will not produce
The situation that stress is concentrated, reduce part and be damaged probability.
