Description
Technical field
The present invention relates to ice breaker technical fields, more particularly to a kind of ice-breaking skates for ice breaker.
Background technique
Ice breaker is to open up navigation channel for being crushed water surface ice sheet, ensures that naval vessel passes in and out ice-bound harbour, anchorage, or guidance warship
Ship is divided into rivers, lake, bay or ocean ice breaker in the ship of ice navigation, usually some to be located in polar region and Han Qu or high
Latitude bay or sea are often ice-bound, and navigation channel is obstructed, and ice generates vessel motion and destroys and influence, therefore, in order to true
The unimpeded of ice Hainan Airlines row is protected, ice breaker just becomes essential tool, and the principle of so-called ice breaker is exactly to utilize hull
Then the weight ballast of itself is crushed in ice face；Second, using the power of ship itself, by downthrust by ice
Layer is broken, to dig course line.In the past all using icebreaking method is collided, this method is to be provided using hull itself by equipment
Power realize that but there is the shortcomings that hull figure are big, ice-breaking is slow, and energy consumption is high, low efficiency for this method；And previous
Ice-breaking thickness is relatively thin, and general thickness will cause often meet with card ice scene when opening up navigation channel so all in 0.3m or so, main
Reason is wanted still to be that structural strength is not able to satisfy.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of ice-breaking skates for ice breaker, it is installed on ice breaker
The ship hull plate of bottom, including one piece of bottom plate and two blocks of symmetrically arranged side plates, side plate, bottom plate and ship hull plate pass through complete penetraction and fusion in welding
Welding forms full-closed structure；Skates are to be attached to that hull middle line keelson is outer and continuous body structure along captain direction arrangement,
Fore body and middle line are in 12 ° of inclination angles of single side, are transitioned into the straight structure to narrow again using gradually wide towards stern, every grade of rib position is equipped with connection one
The frame plate of side side plate is equipped with the plug welding panel for the two to be welded and fixed between frame plate side and side plate.
Technical effect: on the one hand, frame plate, the reinforcement knot as ice-breaking skates transverse direction is arranged by every grade of rib position in the present invention
Structure, by being equipped with plug welding panel between frame plate side and side plate, as the steel sleeve for finally welding side plate, to improve
The generally overall structural strength of the ice-breaking skates of full-closed structure；On the other hand, skates of the present invention are through the continuous of full ship
Structure, fore body point bow are convenient for providing powerful stress point when bow ice-breaking, and gradually broaden towards stern to be transitioned into again straight narrows again
The convenient ice-breaking in ship reversing of structure, while being conducive to the discharge of trash ice, run through full ship to stern, shipping-direction stability can be improved.
It can be seen that structure setting of the present invention by science, ingenious solve ice breaker card ice and the insufficient technology of structural strength is asked
Topic, to increase the thickness of ice-breaking, improves ice-breaking efficiency.
The technical solution that the present invention further limits is:
A kind of preceding ice-breaking skates for ice breaker, towards stern direction 5m within the scope of by arc transition width is increased
It to 2m, transits to width 0.8m in 4m range Inner arc and keeps straight and extend to stern, 2m range is in stern end with single side
12 ° of inclination angles meet at middle line.
A kind of preceding ice-breaking skates for ice breaker, bottom plate, side plate, frame plate and plug welding panel are all made of surrender
The high strength steel of intensity 355MPa or more.
A kind of preceding ice-breaking skates for ice breaker, the vertical outside plate plate thickness calculation of fore body skates:(transverse system),
Wherein, s is stiffener spacing；
Maximum value is 1.0；
Ppl is load, and Ppl=0.75P, P are propeller power；
σy=355MPa；
tc=2mm.
The beneficial effects of the present invention are:
(1) the sharp structure design of skates head and the tail is conducive to efficient ice-breaking in the present invention, and the design of fore body hypertrophy can enhance fore body
The intensity of skates, while it being able to guide trash ice two sides dispersion to the left and right again, it prevents trash ice savings in fore body, ensures that ship can continue
Efficient ice-breaking；
(2) present invention can efficiently, accurately choose suitable thickness according to ice-breaking skates calculation method and pass through software modeling,
Finite element analysis verifying is carried out to intensity of the skates under ice-breaking operating condition, the plate thickness data for meeting design requirement are obtained, to protect
Demonstrate,prove the operating condition validity of ice-breaking skates；
(3) present invention selects low temperature resistant, high-intensitive steel, further enhances the overall structural strength of ice-breaking skates.
Detailed description of the invention
Fig. 1 is stereoscopic schematic diagram of the invention；
Fig. 2 is typical node figure of the present invention；
Wherein: 1, ship hull plate；2, side plate；3, bottom plate；4, plug welding panel；5, frame plate.
