Novel efficient ice-breaker

Abstract

The invention relates to an ice-breaker, in particular to the novel efficient ice-breaker. The novel efficient ice-breaker comprises a front ice breaking frame, a steel wire, a first servo motor, a vertical frame, a horizontal frame, rear rice knifes, a spiral propeller, an ice-breaker body, broadening boards, side ice breaking devices, a lower ice breaking device, an upper ice breaking device, aguiding shaft and hydraulic cylinders. The novel efficient ice-breaker has the advantages that by means of arrangement modes of a central hammerhead and three outer hammerheads of the front ice breaking frame, the transverse and longitudinal ice breaking areas of the front ice breaking frame in an advancing process of the ice-breaker can be increased; the front ice breaking frame breaks ice in advance, which is beneficial to lower the difficulty of subsequent ice breaking of the side ice breaking devices, the lower ice breaking device and the upper ice breaking device; the upper ice breaking device can saw the upper portion of an ice layer, the lower ice breaking device can saw the lower portion of the ice layer, and the cooperative action of a second ice breaking hammer and an ice breaking hammer on the lower ice breaking device is additionally provided, so that the ice breaking efficiency is greatly improved; a piston rod of each hydraulic cylinder pushes and pulls a corresponding rotating part back and forth, so that the corresponding rotating part continuously keeps away from or gets close to the ice-breaker body around a corresponding pin, damage to the ice-breaker body of crushed ice is reduced, and a navigation channel is broadened.

Description

technical field [0001] The invention relates to an icebreaker, in particular to a novel high-efficiency icebreaker. Background technique [0002] With the advancement of science and technology, human activities have expanded from land to sea, including marine transportation, scientific investigations, etc. When the cold winter comes, the sea surface in many areas is frozen, and the frozen sea has a great impact on passing ships. , so an icebreaker is needed to break the ice. There are three commonly used ice breaking methods: one is the back-collision method, that is, the ship moves forward under the push of the rear propeller, and the ice layer is split and smashed by the bow; The tank is filled with sea water, at this time the bow will be raised, and the high horsepower will rush to the ice surface, and then the rear tank will be filled with the front tank, and the ice surface will be crushed by weight; Hit the ice cube with all your mass. The above methods all have a g...

Problems solved by technology

The above methods all have a great impact on the icebreaker itself, causing some damage to the parts on the ship, and the icebreaking efficiency is not high. Therefore, an icebreaker with high icebreaking efficiency and less damage to the parts on the ship is needed.
