Abstract
The invention discloses a duck tail type stern icebreaking structure which comprises a stern and a rudder installed on a rudder horn located at the boat bottom. An inwards inclined duck tail is arranged at the lower end of the stern, and the center line of the stern extends downwards along the upper edge of the duck tail to be provided with a pseudo rudder, and the rudder is located below the pseudo rudder. A triangular ice skate blade is installed on the lower end surface of the pseudo rudder and located behind the rudder, and the space between the ice skate blade and the rudder is 150-250mm. When a boat backs, the duck tail type stern icebreaking structure crushes floating ices through pressing through the duck tail, the ice skate blade can cut open trash ices rushing at the rudder, and therefore impact on a boat body, especially the rudder from the ice blocks can be avoided. The ice-ward side of the pseudo rudder is sharp so that the pseudo rudder can cut open the trash ices rushing at the rudder. Therefore, the duck tail type stern icebreaking structure can improve the icebreaking effect, guarantee boat safety and improve maneuverability.
Description
Technical field
The present invention relates to a kind of boats and ships ice breaking structure, particularly relate to a kind of duck tail formula stern ice breaking structure.
Background technology
Along with the development of science and technology, people expand from land to ocean, shipping industry is also more and more flourishing, carry the transport between continent, some ship also carries polar region goods transport task simultaneously, often need to pass through ice sheet, along with opening up of course line, the Arctic Ocean, boats and ships ice-breaking capacity is also paid close attention to widely.But at the boats and ships of navigation in ice region, because navigation waters temperature is lower, winter can there is a large amount of floating ice in sea, and time serious, sea overallly can freeze and form ice sheet, and this just causes needs freezing or floe field navigation at boats and ships, hull can be subject to the impact of floating ice and ice sheet, although present hull carries out ice formation reinforcement in corresponding region, when accumulating over a long period, easily cause structural damage, add later maintenance and operation cost, and security risk is larger.
Summary of the invention
The object of the invention is to the defect overcoming prior art, a kind of duck tail formula stern ice breaking structure is provided, by the pressing of duck tail, floating ice is crushed when boats and ships fall back, then by the cutting of skates and false rudder, thus remove the impact of ice cube to hull especially rudder from.
For achieving the above object, the present invention proposes following technical scheme:
A kind of duck tail formula stern ice breaking structure, comprise stern, be arranged on the rudder on described hull bottom rudder horn, described stern lower end has intilted duck tail, described stern line of centers is provided with false rudder along duck tail upper limb to downward-extension, and described rudder is positioned at below described false rudder, and described false rudder lower surface is provided with triangle skates, described skates are positioned at described rudder dead aft, and are 150 ~ 250mm with the gap of rudder.
Described duck tail upper limb is positioned at 50 ~ 60mm on Ml water level line in summer.
The tilted angle of described duck Caudad is 45 ~ 50 °, and material is low temperature resistant high strength steel.
Described skates rear end flushes with false rudder aft end face, and material is low temperature resistant high strength steel.
Ice face met by described false rudder is tip shape, and bench section is peltate structure, and material is low temperature resistant forge piece.
Compared with prior art; the duck tail formula stern ice breaking structure that the present invention discloses; by duck stern construction is inwardly arranged in stern lower end; can crush the floating ice on the water surface or ice sheet during boats and ships back operation; the skates and the false rudder above that are positioned at rudder rear can cut ice cube simultaneously, effectively prevent the impact of ice cube to hull especially rudder, protect hull; add the yarage of boats and ships in ice formation, reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of ice breaking structure of the present invention;
Fig. 2 is side sectional view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme of the embodiment of the present invention.
As shown in Figure 1 and 2, disclosed a kind of duck tail formula stern ice breaking structure, comprise stern 1, described stern 1 lower surface is provided with rudder horn, described rudder horn is provided with rudder 2, described stern 1 lower end has intilted duck tail 3, described duck tail 3 is provided with false rudder 4, and described false rudder 4 is positioned on stern line of centers, and extends downward vertically along duck tail 3 upper limb, described false rudder 4 lower surface is provided with triangle skates 5, and described skates 5 are positioned at the dead aft of rudder 2.
Particularly, described duck tail 3 slopes inwardly 45 ~ 50 °, and upper limb is positioned at 50 ~ 60mm above Ml water level line in summer.
Described skates 5 rear end flushes with false rudder 4 aft end face, and and has the gap of 150 ~ 250mm between rudder 2.
Ice face met by described false rudder 4 is tip shape, and bench section is peltate structure.
Stern side is had to the ship of tail springboard, duck tail 3 is distributed in stern lower end except the region of the springboard that truncates.
When real navigation; as run into hull draw back time; floating ice on the water surface or ice sheet crush by duck tail; can not significantly be impacted when hull is retreated; and the skates of below and false rudder can cut the trash ice rushing at rudder; and then protect the safety of rudder, under the cooperation of the screw propeller strengthened through ice formation, increase the yarage of boats and ships in ice formation.
Technology contents of the present invention and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from spirit of the present invention based on teaching of the present invention and announcement; therefore; scope should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present invention and modification should be comprised, and contained by present patent application claim.
