Embodiment Construction

[0016] The following is attached with the manual figure 1 , 2 , 3 further describe the present invention.

[0017] An icebreaker (7) constructed using the present invention operates in an ice region, and its continuous icebreaking mechanism (6) is as follows: figure 1 The continuous ice-breaking mechanism includes two sprockets (2), a transmission chain (1), a sprocket bracket (5), and each sprocket also includes a sprocket shaft (4) and a bearing (3). Wherein, the transmission chain (1) is connected to the sprocket (2), and the sprocket support (5) is connected to the supporting sprocket (2) through the sprocket shaft (4) and the bearing (3). One sprocket (2) is positioned above the ice layer (8), and one sprocket (2) is positioned below the ice layer (8). Chain wheel support (5) is fixed on the icebreaker (7) hull.

[0018] A total of three sets of the continuous icebreaking mechanism (6) are installed on this icebreaker (7), such as figure 2 . Wherein, a set of the c...

Abstract

The invention relates to the field of the icebreaking mechanism, in particular to a continuous icebreaking mechanism applied to the icebreaking operation requirement of an ocean or a lake and an icebreaker constructed by the icebreaking mechanism. The continuous icebreaking mechanism comprises at least two chain wheels, a transmission chain and a chain wheel bracket, wherein each chain wheel also comprises a chain wheel shaft and a bearing; the transmission chain is connected with the chain wheels; the chain wheel bracket is connected with the chain wheels and supports the chain wheels by the chain wheel shafts and the bearings. During work, at least one chain wheel is positioned above the ice layer, and at least one chain wheel is positioned below the ice layer. The transmission chain passes through and rubs the ice layer, and the chain wheel bracket is fixedly arranged on a ship body. The continuous icebreaking mechanism and the icebreaker have the advantages that the ice layer is damaged with small strength instead of crushing the ice layer by the gravity of the ship body. A certain angle is formed between the cut and damaged ice layer and the surrounding ice layer to reduce the resistance of the ship body for extruding the ice layer, so that the requirement on the propeller of the icebreaker and the related facilities is effectively lowered, and the icebreaking efficiency is improved.

Description

technical field [0001] The invention relates to the field of ice-breaking mechanisms, in particular to a continuous ice-breaking mechanism applicable to ocean or lake ice-breaking operations and an icebreaker constructed from the ice-breaking mechanism. Background technique [0002] During cold seasons, ice in oceans or lakes can damage and affect passing ships. Existing ice-breaking methods mainly include: bumping method, with the forward power of the icebreaker, the ice layer is crushed by the hull; First pump the water in the hull to the aft cabin, then drive the raised bow to the ice, then pump the water in the aft cabin to the front cabin, and crush the ice with the weight of the water. These methods all put forward higher requirements to the hull structure, propulsion device and its auxiliary facilities, etc., and the ice-breaking speed is not fast. [0003] It is time to invent an economical and fast icebreaker. Contents of the invention [0004] The purpose of t...
