The principle of ice breaking of an icebreaker is as follows: compared with other ships, the icebreaker has the characteristics that: the bow of the ship is in a broken line shape, so that the bottom line of the head forms an angle of 20 to 35 degrees with the horizontal line, and the bow can climb to the ice surface; the two sides of the bow, the stern and the side of the ship are all provided with large water tanks as ice breaking equipment. When the icebreaker encounters an ice layer, the raised bow climbs the ice surface, and the ice is crushed by the weight of the bow part. In order to crush the ice layer, the weight of the bow is generally required to reach about 1000t, and the icebreaker can easily crush the ice layer which is not firm. Of course, if a firmer ice layer is encountered, the ice layer can not be broken by the method, the icebreaker usually needs to retreat a certain distance in sequence, then the opening horsepower rushes away, and the ice layer is broken away by the inertia of the icebreaker. If the ice breaker encounters a very thick ice layer and is not opened after being impacted for several times, the ice breaker can fill the water tank at the tail part by using the water pump, so that the center of gravity of the ship moves backwards, the bow of the ship is lifted, at the moment, the horsepower is achieved, the ice breaker "climbs" the ice surface, then the water in the water tank at the tail part is pumped out, and the water in the water tank at the bow part is filled, so that the gravity of the bow of the ship is very large, and the very thick ice layer can be crushed. In this way the ice-breaker will slowly move forward, opening a passage over the ice.
The climbing type ice breaking mode of the ice breaker causes large strength such as abrasion and extrusion of an ice layer on the bow of the ice breaker, and the damage is easily caused; therefore, in order to reduce damage to the bow of the ship and improve the ice breaking effect, a plurality of devices for assisting ice breaking are provided in the prior art, but most of the devices adopt a mode of converting electric energy into mechanical energy or kinetic energy to chisel the ice layer, so that a large amount of energy is consumed.
