Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below with reference to accompanying drawings and embodiments,
The present invention is described in more detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
As shown in Figure 1, a kind of disclosed more body arctic navigation ships, are made of, hull is mainly wrapped multiple hulls
Include ice-breaking forepart construction 1, cargo component 2, stem ballast tank 3 and tail portion ballast tank 4, cabin 5, the catheter type propeller 6 of tail portion,
Superstructure 7.
The hull is asthenic watertight cabin structure, and the streamlined structure of hull is symmetrically arranged.The ice-breaking ball
The first column of first structure design underwater is oblique, and with baseline about at 30 ° of angles, inside carries out structural strengthening.The hull knot
The outside plate of structure is reinforced in different range:Outside plate is divided into using high-order ice formation water line and low level ice formation water line
Different zones, the ice bank region between high-order ice formation water line and low level ice formation water line have carried out different degrees of reinforcement,
Reinforcement method is using plate thickness is increased, and the spacing for reducing lateral aggregate is to increase the quantity of lateral aggregate, and outside plate uses the height of H ranks
Strength steel, shell envelope framing use transverse system, inside framework to use longitudinal framing.The ice-breaking forepart construction uses top slat iron
Formula, rib cage arrangement is more close, has been longitudinally arranged strong girder, such as T profile.Bow plate uses low temperature resistant high-strength steel sheet, energy
Resist the low temperature environment of polar region.
As shown in Figure 1, the ice-breaking forepart construction 1 is additionally provided with skates 8 near designed draft line.3 He of stem ballast tank
It is interconnected respectively by the first solenoid valve 102 and the first ballast pump 103 between tail portion ballast tank 4.
As shown in Fig. 2, catheter type propeller 6 is installed on the quarter of port and starboard outermost hull, protect propeller not by
The shock of floating ice.Preferably, intermediate hull can also install propeller, and propeller can be conventional propeller, conduit spiral
Paddle, water hanging cabin propeller driving etc. are one such.Left side ballast tank 9 and right side ballast are further respectively had at left and right sides of Ship Structure
Cabin 10 is interconnected between left side ballast tank 9 and right side ballast tank 10 by second solenoid valve 202 and the second ballast pump 203.
As shown in figure 3, when ship needs ice-breaking to navigate by water, the water in stem ballast tank 3 is evacuated to by the first ballast pump 103
Tail portion ballast 4, makes stem tilt, and then rushes to ice sheet 105.Then such as Fig. 4, then the water in tail portion ballast tank 4 is evacuated to stem
Ballast tank 3, the weight by water crush ice sheet, collide ice sheet repeatedly and realize ice-breaking.
As shown in figure 5, adjusting left side ballast tank 9 and right side ballast with the second ballast pump 203 and second solenoid valve 202 simultaneously
The water level in cabin 10 makes ship be swung left and right, and the ice sheet on both sides is crushed.Expand the ice-breaking region of ship both sides, ensures that ice navigation manipulates
Performance.So that bow is pressed to ice sheet, and rely on its own gravity pressure break ice sheet, collides ice sheet repeatedly and realize ice-breaking.
It is the workspace and living area of crewman as shown in Figure 1, the superstructure 7 is located on the main hull structure, far
It disembarks cabin 5, ensures the life of crewman not excessive noise and vibration.Superstructure 7 is located at bow including driver's cabin 701, behaviour
Ship person there's is unobscured, and blind area is smaller, ensures for avoiding ice sheet in time in the polar region environment navigation of ice condition complexity
Safe navigation is more important.Such as Fig. 2, for driver's cabin 701 in the top layer of superstructure 7, driver's cabin extends to wingshelter arrangement,
Width arranges more than the beam, and the forward and backward face of driver's cabin and side are equipped with electrically heated glass window 702, and operator can when ship berthing
To be directed through or open windowpane observation ship side both sides and front and back ice condition and mooring situation in both sides, make ship in polar ice
There is the good visual field when berthing of area harbour.
There is more body arctic navigation ships good ice formation stability, metacentric height to be more than 0.5m or more, freeboard deck side
The margin line of 150mm is not also submerged when lateral inclination occurs in ship under the action of floating ice under edge line.Also have good broken
Cabin stability, when deck in ship structure, exposure hatchcover etc. are by snow and ice cover, after ice sheet collision causes cabin damage and water inflow, ship leaching
Final waterline after water is located at may be by the lower section for any opening lower edge for continuing to soak downwards that is open.The opening includes empty
Tracheae, ventilator and the opening closed with weathertight door or weathertight cover.Initial metacentric height of the ship under Riddled Condition
It is always positive value.
The technology contents and technical characteristic of the present invention have revealed that as above, however those skilled in the art still may base
Make various replacements and modification without departing substantially from spirit of that invention, therefore, the scope of the present invention in teachings of the present invention and announcement
It should be not limited to the revealed content of embodiment, and should include various replacements and modification without departing substantially from the present invention, and be this patent Shen
Please claim covered.
