Abstract
The invention belongs to the technical field of ships and relates to an icebreaker comprising a hull. The head of the hull is provided with a deicing mechanism. The deicing mechanism comprises a hydraulic cylinder, fixing blocks, crankshafts, two first saw blades, and a second saw blade. One crankshaft is mounted between every two fixing blocks. The first saw blades are mounted on the outer sides of the crankshafts. The second saw blade is mounted on the inner sides of the crankshafts. One end of the hydraulic cylinder is fixed to the hull, and the other end of the hydraulic cylinder is fixed to one crankshaft. Just the saw-tooth structure of the icebreaker is used to saw ice open, stress of sawing up and stress of sawing down are mutually canceled so that the icebreaker can break the ice as running in a still sea and never severely shake, damage of instruments inside can be effectively prevented, and the icebreaker is long in service life.
Description
Technical field
The present invention relates to a kind of icebreaker, belong to technical field of ships.
Background technology
Along with scientific and technological development, people are from land to ocean expansion, and shipping industry is also more and more flourishing, bearing the transportation between continent, but the manufacture of boats and ships is particularly difficult, especially icebreaker, bear the work of opening ice, all adopt at present by inner ballast tank water level and regulate, fore is upwarped and have a downwarp to crush ice face, although can open ice like this, can cause the equipment left side on ship to shake right rolling, especially scientific instrument are easy to damage, and are urgent problems.
Summary of the invention
The object of this invention is to provide a kind of icebreaker.
The problem to be solved in the present invention is the open ice deficiency of fragile instrument of existing rocking.
For realizing object of the present invention, the technical solution used in the present invention is:
A kind of icebreaker, comprise hull, described hull head is provided with deicing mechanism, deicing mechanism comprises hydraulic actuating cylinder, fixed block, bent axle, the first saw blade and the second saw blade, between two fixed blocks, bent axle is installed, bent axle outside is provided with two the first saw blades, and inner side is provided with a slice the second saw blade, hydraulic actuating cylinder one end is fixed on hull, and the other end is fixed on bent axle.
Described bent axle is two protruding recessed structures, and two are provided with the first saw blade, recessed second saw blade that is provided with on protruding.
Described the first saw blade and the second saw blade are provided with a plurality of sawtooth, the sawtooth opposite direction of the first saw blade and the second saw blade, and the tooth width of the first saw blade is 1/2 of the second saw blade.
Advantage of the present invention is: this ship adopts broached-tooth design to cut ice face, and stressed cancelling out each other while sawing up and down, make when opening ice, ship is just as travelling on tranquil sea, can not produce violent rocking, can effectively prevent the damage of interior instrument, long service life, has very high using value.
Accompanying drawing explanation
Fig. 1 is the lateral plan of a kind of icebreaker of the present invention;
Fig. 2 is the front view of a kind of icebreaker of the present invention;
In figure: 1, hull 2, deicing mechanism 3, hydraulic actuating cylinder 4, fixed block 5, bent axle 6, the first saw blade 7, the second saw blade.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in the figure, a kind of icebreaker, comprise hull 1, described hull 1 head is provided with deicing mechanism 2.
Described deicing mechanism 2 comprises between hydraulic actuating cylinder 3, fixed block 4, bent axle 5, the first saw blade 6 and 7, two fixed blocks 4 of the second saw blade bent axle 5 is installed, and totally two suite axles 5, for fixing up and down the first saw blade 6 and the second saw blade 7; Bent axle 5 outsides are provided with two the first saw blades 6, and inner side is provided with a slice the second saw blade 7, and hydraulic actuating cylinder 3 one end are fixed on hull 1, and the other end is fixed on bent axle 5.
Described bent axle 5 is two protruding recessed structures, and two are provided with recessed second saw blade 7 that is provided with of the first saw blade 6, on protruding, so just can form differential work simultaneously up and down.
Described the first saw blade 6 and the second saw blade 7 are provided with a plurality of sawtooth, the sawtooth opposite direction of the first saw blade 6 and the second saw blade 7, and the tooth width of the first saw blade 6 is 1/2 of second saw blades 7, the moment that both and the cutting of ice face produce like this can be cancelled out each other, and good stability and the moment of torsion that opens ice are also large.
The using method of a kind of icebreaker of the present invention: when ship navigates by water in ice face region, by the hydraulic efficiency pressure system in hull to hydraulic actuating cylinder 3 energy supplies, make it flexible, and be with dynamic crankshaft 5 to rotate, because bent axle 5 exists displacement difference, at the first saw blade 6 downwards time, the second saw blade 7 upwards, carries out the cutting of ice face and opens ice, and moment is offset mutually simultaneously, and it is effective to open ice, hull stationarity might as well.
