Description
Technical field
The present invention relates to and a kind ofly solve high speed vessel because of shipping of green water and affect the arc foreship stem line structure of ship performance.
Background technology
At present, along with the development of Ship Design Technology, the requirement of people to the quick performance of boats and ships also improves thereupon, and thus increasing high-speed ship emerges in large numbers in succession; But major part does not possess gratifying rough water quality in them, and seasick rate is very high.Cause the appearance of this situation mainly because ship's navigation forms a large amount of waves under fast state, the wave punching of rising causes vessel roll and suffered resistance to increase to deck, thus cause ride on personnel safety on ship and traveling comfort very poor, occur very high seasick rate, serious shipping of green water even may cause toppling of boats and ships.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of arc foreship stem line structure of dredging high speed vessel shipping of green water of research and design, navigate by water under fast state in order to solve existing high-speed ship, the problem of what shipping of green water caused affect ship performance.The technological means that the present invention adopts is as follows:
Dredge an arc foreship stem line structure for high speed vessel shipping of green water, described stem exterior hull comprises: arrange unrestrained portion and main part, the unrestrained portion of described row comprises: flat part, streamline portion, concave part, curved portions and rake, the main part of arc is provided with below the hull of described stem outside, described main part top is connected with the flat part arc of row bottom, unrestrained portion, streamline portion is connected with above described flat part, described streamline portion is outside to hull interior direction from hull, be 2 degree-5 with level attitude angle upward to spend, above described streamline portion, fairing transition is connected with concave part, above described concave part, fairing transition is connected with curved portions, described curved portions is from hull interior to hull outside direction, be 47 degree-57 with the angle of level attitude upward to spend, rake is provided with above described curved portions, described rake is outside to hull interior direction from hull, be 7 degree-13 with the angle of level attitude upward to spend, other structure arcs of row's wave portion and main part and hull of described stem exterior hull are connected.
Account for 1/3rd of hull total length as the preferred unrestrained portion of described row, and row's wave portion of hull both sides is symmetrical.
Be rectilinear plate structure as preferred described flat part.
It is 3 degree with level attitude angle upward as preferred described streamline portion.
Be stream line pattern fairing groove as preferred described concave part inside.
It is 52 degree with the angle of level attitude upward as preferred described curved portions.
It is 10 degree with the angle of level attitude upward as preferred described rake.
Compared with the prior art, a kind of arc foreship stem line structure of dredging high speed vessel shipping of green water of the present invention, stem exterior hull has the unrestrained portion of row, when high-speed ship navigates by water under fast state, the wave risen more than deck will rush the rake to arranging in unrestrained portion, then skid off beyond hull along rake, rise the wave below deck, can the concave part in unrestrained portion of the row of getting to, decrease impulsive force, flow out along streamline portion and flat part again, discharge beyond hull, reduce the resistance suffered by ship's navigation process, reduce oil consumption, improve the rough water quality of boats and ships, also improve safety and the traveling comfort of boats and ships, actv. solves the problem that shipping of green water affects ship performance.

Fig. 2 is plan structure schematic diagram of the present invention.
Fig. 3 is the structural representation that unrestrained portion is arranged in hull side of the present invention.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of arc foreship stem line structure of dredging high speed vessel shipping of green water, described row's wave portion 1 accounts for 1/3rd of hull total length, and described stem exterior hull comprises: arrange unrestrained portion 1 and main part 2, row's wave portion 1 of hull both sides is symmetrical, and the unrestrained portion 1 of described row comprises: flat part 11, streamline portion 12, concave part 13, curved portions 14 and rake 15, the main part 2 of arc is provided with below the hull of described stem outside, described main part 2 top is connected with flat part 11 arc of row bottom, unrestrained portion 1, described flat part 11 is rectilinear plate structure, the wave that can block flat part less than 11 does not impact the unrestrained portion 1 of row, can discharge easily beyond hull by the wave in unrestrained portion 1 of the row of allowing, strengthen the rough water quality of ship, streamline portion 12 is connected with above described flat part 11, described streamline portion 12 is outside to hull interior direction from hull, be 2 degree-5 with level attitude angle upward to spend, preferred angle is 3 degree, make the wave in streamline portion 12 easier to the outflow of hull outside, above described streamline portion 12, fairing transition is connected with concave part 13, described concave part 13 inside is stream line pattern fairing groove, concave part 13 in the unrestrained portion 1 of described row forms conduit from bow to stern, most of wave that ship navigation process middle front part is started can be discharged beyond hull by the unrestrained portion 1 of row, above described concave part 13, fairing transition is connected with curved portions 14, described curved portions 14 is from hull interior to hull outside direction, be 47 degree-57 with the angle of level attitude upward to spend, preferred angle is 52 degree, the wave rushing at hull is made to beat on concave part 13 and curved portions 14, serve the effect of buffering, alleviate rocking of hull, enhance the stability of hull, rake 15 is provided with above described curved portions 14, described rake 15 is outside to hull interior direction from hull, be 7 degree-13 with the angle of level attitude upward to spend, preferred angle is 10 degree, the wave energy rushing to deck is made to flow out hull from rake 15 easily, avoid entering inside, deck, a large amount of seawater is made to swarm deck, avoid huge impulsive force can to the equipment on deck, goods and superstructure etc. damage, cause the goods on deck also may to be broken up, cause huge loss, other structure arcs of row's wave portion and main part and hull of described stem exterior hull are connected.
During ship's navigation, very large wave can be started, the wave risen more than deck will rush the rake 15 to arranging in unrestrained portion 1, then skid off beyond hull along rake 15, rise below deck, the wave of flat part more than 11, can the concave part in unrestrained portion 1 of the row of getting to, decrease impulsive force, flow out along streamline portion 12 and flat part 11 again, discharge beyond hull, decrease the impulsive force that wave causes hull, improve the rough water quality of boats and ships, also improve safety and the traveling comfort of boats and ships, reduce the resistance suffered by ship's navigation process, reduce oil consumption, actv. solves shipping of green water affects ship performance problem.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
