Further, least draught waterline intersects with rake 01.When ship is with least draught regimes, table on ice sheet
Face is contacted with rake 01, so that ship was generated using forward impact force, the gravity of ship itself and ship self gravity
To the impact force of ice sheet, Lai Jinhang ice-breaking.In this way, ship is when with the navigation of lesser draught amount, it may have stronger icebreaking characteristics,
And the power consumed by ice navigation is lower.
Further, the lower end of rake 01 extends in the range of 30%T-34%T.
In some embodiments, the lower end of rake 01 extends at 32%T, so that ship is in extreme draft state and most
When range between snack water state is navigated by water, foremost part of ship keeps higher icebreaking characteristics to trash ice and layer ice.
Further, the intersection of the outer wall of rake 01 and central fore-and-aft vertical plane 05, along linear extension.
Specifically, referring to Fig.1 and 2, the front side of rake 01 is set as straight line, so that ship is in different drinking water states
When, foremost part of ship keeps stablizing to the size and Orientation of the active force of ice sheet, so that icebreaking characteristics be made to keep stablizing, avoids ship
In lower drinking water regimes, icebreaking characteristics are reduced and consumed power increases.
Further, the intersection of the outer wall of rake 01 and central fore-and-aft vertical plane 05, the angular range between Water Plane are
55°-65°。

60 ° are set to, is conducive to ship in this way and on the one hand applies downward pressure and impact force to ice sheet using self gravity, carry out brokenly
Ice；On the other hand the side of foremost part of ship and ice sheet is made to keep biggish contact area, to apply ice sheet along preceding line direction
Impact force, Lai Jinhang ice-breaking.Foremost part of ship applies the active force of multiple directions to ice sheet, improves ice-breaking capacity and ship in ice
The navigation performance in area.
Further, the intersection of lower extension 02 and central fore-and-aft vertical plane 05 is set as circular arc line, and is directed toward the direction of bow
Protrusion.
Specifically, referring to figure 2., first column is by lower extension 02, to hull bottom arc transition.Lower extension 02 it is general not into
Row ice-breaking, lower extension 02 keep foremost part of ship transition more smooth.During forward, lower extension 02 is conducive to guide ship
Trash ice is moved to hull bottom and hull two sides, reduces trash ice in water to the forward generation resistance of ship.
Moreover, lower extension 02 is conducive to during so that ship is moved ahead, the water flow of foremost part of ship is more smooth, so that stem
Waveform comparison is steady, reduces wave making resistance.
In some embodiments, lower extension 02 extends to bilge keel.
Further, the intersection of upper extension 03 and central fore-and-aft vertical plane 05, along linear extension.Upper extension 03 and central fore-and-aft vertical plane
05 intersection, perpendicular to Water Plane.In this way, being conducive to improve the stationarity of ship's navigation process.
As another embodiment, the intersection of upper extension 03 and central fore-and-aft vertical plane 05 is obliquely installed relative to Water Plane；
Also, angle between the two, greater than the angle between the outer wall of rake 01 and the intersection and Water Plane of central fore-and-aft vertical plane 05.
Further, the outer wall of foremost part of ship be parallel to midship section plane intersection, with extreme draft waterline
The tangent line of 04 point of intersection, the angle between Water Plane are gradually increased along bow to the direction of stern.
Specifically, ship is divided into 20 stations along length between perpendiculars, from stern to bow, respectively 1 station to 20 stations；Bow portion
The contour line for dividing the cross section at each station, projects on midship section, perspective view is referring to figure 3. respectively.
The contour line in each station cross section, the folder in the tangent line of the point of intersection with extreme draft waterline 04, between Water Plane
Angle is gradually increased along bow to the direction of stern.Thus it is possible, on the one hand, reducing the contact with ice sheet when foremost part of ship hits ice sheet
Area is conducive to rupture ice sheet to increase the pressure that ice sheet is knocked part, improves icebreaking characteristics.On the other hand, ship is first
Portion, to ship middle and lower part smooth transition, is conducive to that trash ice is guided to move to the two sides of hull bottom and hull along curved surface, reduces trash ice and exists
Accumulation above ice sheet, to reduce trash ice to the resistance of ship's navigation.
Moreover, ice-breaking type ship stem provided in an embodiment of the present invention makes water flow movement more smooth, stem waveform is more
Add steadily, reduce wave making resistance, is conducive to the quick sailing performance for improving ship.
In some embodiments, foremost part of ship extends to 19 stations from 20 stations.Cross section at 20 stations with extreme draft water
The tangent line of the point of intersection of line 04, the angle between Water Plane are 52 °；
The tangent line of cross section at 19.75 stations in the point of intersection with extreme draft waterline 04, angle between Water Plane
It is 64 °；
In the tangent line of the point of intersection with extreme draft waterline 04, the angle between Water Plane is for cross section at 19.5 stations
70°；
In the tangent line of the point of intersection with extreme draft waterline 04, the angle between Water Plane is for cross section at 19 stations
78°。
Further, referring to figure 4., in the point of intersection of extreme draft waterline 04 and central fore-and-aft vertical plane 05, extreme draft waterline
Angular range between 04 tangent line and central fore-and-aft vertical plane 05 is 55 ° -60 °, and during moving ahead to avoid ship, ice sheet is to ship head
The reaction force in portion is excessively concentrated, and the stability to move ahead to ship adversely affects；Meanwhile being conducive to that ice sheet is made to receive ship
The forced area of oceangoing ship stem impact force is smaller, increases local pressure, is conducive to ice-breaking.
In some embodiments, in the point of intersection of extreme draft waterline 04 and central fore-and-aft vertical plane 05, extreme draft waterline 04
