China's 13th Arctic Ocean Scientific Expedition
Depart from Shanghai on the "Xuelong 2"
A scientific expedition to the Arctic Ocean
The "Xuelong 2" on which the expedition team flew
What makes you stand out?
Look down and learn about ↓ together
First! Two-way icebreaker
"Xuelong 2" was built independently by Continental
The world's first two-way icebreaker research vessel
It can easily cross a 20-meter ice ridge
Can be easily broken
1.5 meters high ice, 0.2 meters thick snow
It is a well-deserved great power heavy weapon
It is understood
The mission of this inspection mainly covers
The Pacific sector of the Central Arctic Ocean and the Mid-Gulf Ridge of the Gark Ocean
The total range is expected to be approximately 15,500 nautical miles
Returned to Shanghai in late September
This visit will be carried out
Long-term monitoring of key environmental elements,
Mid-ocean ridge geological and geophysical surveys,
The four major tasks of national science and technology plans and international cooperation
This polar research vessel
There are intangible cultural heritage skills that have been passed down for thousands of years
"Snow Dragon 2"
The reason why it can be in the cold polar regions
Unimpeded, safe sailing
With the one it adopts
The intangible cultural heritage skills passed down for thousands of years are inseparable
Watertight compartment boat manufacturing technology
"Xue Long 2" from bow to stern
There are 9 watertight bulkheads in total
Form 10 separate compartments
Can make "Snow Dragon 2"
Sail safely and steadily at the North and South Poles
Fukufune is characterized by watertight compartments that are independent of each other
Even if a certain cabin is broken
It also does not affect other classes
Moreover, the compartment structure is convenient for cargo compartment management
Reduce cargo damage rate
It also helps to improve the safety and stability of the vessel
Fukufune has created many miracles in history
Zheng He went to the West and Qi Jiguang resisted
……
All of them are fukushi
Watertight compartment boat manufacturing technology
Why can ships be kept leak-proof?
What are the steps of this manufacturing process?
The manufacturing process is complex
From fixed keels to anxi dwarf beams, beams, bull heads
To the nail bottom plate, walking horse, water snake
Then to seams, lacquer painting
Finally, to the masts, the vertical sails...
Among them, the seam is used
Tung oil, lime powder, hemp silk these natural materials
Plaster the bottom in the seam first
Fill the hemp according to the size of the gap
Then fill the putty and smooth the surface
Thus ensuring the watertightness of the ship
From fishing ships to merchant ships, from warships to official ships
The contribution of Fukufune's craftsmanship is everywhere
Today, container ships, aircraft carriers
It is still from the craftsmanship of Fukufune
Draw on wisdom
This is the cohesion of ingenuity passed down from generation to generation
It is also the vitality of intangible cultural heritage
