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
The present invention relates to ice-breaking mechanism field, particularly a kind of continuous ice-breaking mechanism of ocean or lake icebreaking service demand and ice breaker that ice-breaking mechanism is configured to thus of being applied to.
Background technology
In cold season, the ice in ocean or lake produces and destroys and impact the boats and ships of process.Existing icebreaking method mainly comprises: answer back to method, the power advancing with ice breaker, squeezes trash ice layer by hull; Collision method, ice breaker is first moveed backward, slow astern segment distance, then full ahead both, crashes ice sheet; Heap ponding icebreaking method, is first extracted into rear deck by the water in hull, then the fore lifting is reached on ice face, then again the water of rear deck is extracted into front deck, by the weight crushing ice sheet of water.These methods all propose higher requirement to Ship Structure, propulsion plant and ancillary facility thereof etc., and the speed that opens ice is also unhappy.
Required when inventing a kind of economy ice breaker being fast.
Summary of the invention
The object of the invention is for the existing demand that opens ice in ocean or lake, propose a kind of safe and efficient, do not damage the continuous ice-breaking mechanism of hull and ice-breaking mechanism is configured to thus ice breaker.
The present invention is achieved in that continuous ice-breaking mechanism only comprises two sprocket wheels less as described in Figure 1, a driving-chain, and chain wheel support, each sprocket wheel also includes sprocket shaft and bearing.Wherein, driving-chain connects sprocket wheel, and chain wheel support is connected supporting wheel by sprocket shaft with bearing.When work, only a sprocket wheel is positioned on ice sheet less, only lacks one and is positioned under sprocket wheel ice sheet.The driving-chain ice sheet that passes and rub.
Chain wheel support of the present invention is fixed on hull.The present invention rotates by loading power source drive sprocket on hull, also just drives the driving-chain ice sheet that rotates and rub simultaneously, and ice sheet is cut.
Described continuous ice-breaking mechanism also can comprise three or with upper sprocket wheel, like this, is not changing under the length prerequisite of driving-chain, can be by changing the position between sprocket wheel, to tackle the ice sheet of different thickness.
The described continuous ice-breaking mechanism of three covers is installed, as Fig. 2 on ice breaker.Wherein, icebreaker bow hits exactly a vertical installation sleeve described continuous ice-breaking mechanism.A set of described continuous ice-breaking mechanism is respectively installed in icebreaker bow both sides.Two cover continuous ice-breaking mechanism driving-chains and the ice sheet of bow both sides have certain angle; The driving-chain of the described continuous ice-breaking mechanism of two covers of bow both sides is to take center line of boat as axisymmetric, and between the driving-chain of the described continuous ice-breaking mechanism of two covers of bow both sides, distance is not less than hull the widest part.
As Fig. 3, when work, the effect that is positioned at the described continuous ice-breaking mechanism of bow center is from middle cutting damage ice sheet.Ice breaker is pushed ahead in driving mechanism effect, and hull pushes the ice sheet of cutting damage to both sides.The effect that is positioned at the described continuous ice-breaking mechanism of two covers of bow both sides has two: the one, and cutting damage ice sheet, the 2nd, make the cut ice sheet that destroys produce certain angle with ice sheet around, like this, under hull squeezing action, because there is certain angle, the cut ice sheet that destroys is better pressed against around under ice sheet.
Further, transmission chain and sprocket of the present invention, if be transformed to driving-belt and belt wheel, also has the close effect that opens ice.Belong to equally right of the present invention.
The invention has the advantages that: with less power, ice sheet is destroyed, rather than rely on the gravity of hull that ice sheet is crushed.Make the cut ice sheet that destroys produce certain angle with ice sheet around, reduce the resistance of hull extruding ice sheet.Thereby effectively reduce the requirement to the propeller of ice breaker and related facility, improve the efficiency that opens ice.

In figure, 1 driving-chain, 2 sprocket wheels, 3 bearings, 4 sprocket shafts, 5 chain wheel supports, 6 continuous ice-breaking mechanisms, 7 ice breakers, 7.1 center lines, 8 ice sheets, the ice sheet of 8.1 fragmentations, 8.2 ice sheets around, 9 navigation channels.
The specific embodiment
Below in conjunction with Figure of description 1,2,3, the invention will be further described.
One is used ice breaker (7) that the present invention is configured in ice formation operation, its continuous ice-breaking mechanism (6) is such: continuous ice-breaking mechanism comprises two sprocket wheels (2) as described in Figure 1, a driving-chain (1), chain wheel support (5), each sprocket wheel also includes sprocket shaft (4) and bearing (3).Wherein, driving-chain (1) connects sprocket wheel (2), and chain wheel support (5) is connected supporting wheel (2) by sprocket shaft (4) with bearing (3).A sprocket wheel (2) is positioned on ice sheet (8), and a sprocket wheel (2) is positioned under ice sheet (8).Chain wheel support (5) is fixed on ice breaker (7) hull.
The described continuous ice-breaking mechanism of three covers (6) is installed altogether, as Fig. 2 on this ice breaker (7).Wherein, fixing a set of described continuous ice-breaking mechanism (6) is vertically installed in ice breaker (7) bow center.Each installs fixing a set of described continuous ice-breaking mechanism (6) ice breaker (7) bow both sides, and the driving-chain (1) of two cover continuous ice-breaking mechanisms (6) of bow both sides has certain angle with ice sheet (8); The driving-chain (1) of these two described continuous ice-breaking mechanisms of cover (6) is to take center line of boat (7.1) as axisymmetric, and between the driving-chain (1) of the two described continuous ice-breaking mechanisms of cover (6) of bow both sides, distance is greater than ice breaker (7) hull the widest part.
As Fig. 3, when ice breaker (7) is advanced before the introversion of navigation channel (9), driving-chain (1) power source of three cover continuous ice-breaking mechanisms (6) drives lower quick rotation, rub and cut ice sheet (8), cut broken ice sheet (8.1) is pulled to navigation channel (9) around under ice sheet (8.2) under the extruding of ice breaker (7) hull.
