Embodiment 1

[0023] The hull structure of an ice skid-type icebreaker tugboat provided in this embodiment, such as figure 1 As shown, it includes the hull frame, the stern of the semi-ice row ship, the tipped forward tilting bow and the main deck 2, the half ice row ship stern includes the stern inclined outer plate 1 and the stern drum 11, and the tipped forward tipping bow includes The bow sloping outer plate 3 and the raised main deck 9, the hull frame includes a longitudinal frame 5, a transverse bulkhead 4 and a watertight transverse bulkhead 8, and the transverse bulkhead 4 and the watertight transverse bulkhead 8 are respectively vertically fixed to the longitudinal frame 5, The bow part of the hull frame is vertically fixed with the first bow sweeping and longitudinal bulkhead 7.1 and the second bow sweeping and longitudinal bulkhead 7.2, and the stern part of the hull frame is vertically fixed with the stern sweeping and longitudinal bulkhead 7.3. The first bow sweeping longitudin...

Abstract

The invention discloses an ice prying type icebreaking tug ship structure, and belongs to the technical field of ship manufacturing. The ice prying type icebreaking tug ship structure includes a shipframe, a half-row ice ship stern, a sharpened forward-leaning type ship bow and a main deck; the half-row ice ship stern includes a stern inclined outer plate and a stern drum, the sharpened forward-leaning type ship bow includes a bow inclined outer plate and a lifting main deck, and the ship frame includes a longitudinal frame, a transverse bulkhead and a water-tight transverse bulkhead; and anincluded angle between the stern inclined outer plate and the horizontal plane is alpha degrees, an included angle between the bow inclined outer plate and the horizontal plane is beta degrees, wherein the alpha degrees are 17 degrees, and the beta degrees are 25 degrees. According to the ice prying type icebreaking tug ship structure, the included angle between the bow inclined outer plate and the horizontal plane is beta degrees, the requirement of an icebreaking grade is met, and broken ice smoothly entering the bottom of a ship and being discharged through the tail part is facilitated; andthe included angle between the stern inclined outer plate and the horizontal plane is alpha degrees, the smooth discharging of the broken ice along the stern inclined outer plate is facilitated, andthe damage to a propeller due to the fact that the broken ice is separated from the ship outer plates is prevented.

Description

technical field [0001] The invention relates to a hull structure of an ice-skimming type ice-breaking tugboat, belonging to the technical field of shipbuilding. Background technique [0002] The polar icebreaker is the key force for countries to implement the bipolar strategic layout and expand the strategic space. Responsible for the scientific investigation of the polar regions and the realization of the task of supplying materials to the polar research stations, etc., are the basic conditions for reaching the core areas of the polar regions to carry out polar scientific expedition operations. At the same time, it is also an important tool for the development and maintenance of shipping channels in the ice area, to ensure the smooth flow of polar routes and to open up new routes. As a traditional permanent observer of the Arctic Council, China is imminent to develop icebreaker technology. [0003] my country's icebreaker design is still in its infancy. Although good achi...
