How is the underwater photographer of 10,000 meters tempered?

The secret is a pressure-resistant dry cabin, which consists of a titanium alloy cabin and a transparent window at the back, and an O-ring is installed at their joint. When diving, the offshore seawater will squeeze these rubber rings into the joint to form a "water-tight" sealed cabin. In addition to the lens problem, The Sea is also equipped with a lighting system.

Generally, the sunlight illumination below 200 meters underwater is less than 0.0 1% of the water surface illumination. /kloc-The deep sea below 0/000 meters is dark. If you want to see the strugglers, you must polish them. In order to meet three different lighting needs on the seabed, Canghai was equipped with four HMI and 12 LED lights, which enabled him to spend 10 hours in the deep sea. Each lighting lamp in the light array has its own numbering and control system, which can meet different underwater lighting conditions and lighting requirements.

In February 2020, Endeavour completed the final assembly and land debugging as planned, and conducted a pool test in March. In the pool test, * * * completed 25 test tasks including the whole process evaluation, and several submersibles conducted pool diving training.

On April 22, 2020, the 10,000-meter manned submersible was officially launched. After the launch of the activity, a wave of "talent contest" was launched on the Internet. After receiving the names of nearly 654.38 million netizens, after some fierce fighting, the top ten celebrities were recorded. Then an evaluation team composed of special representatives, the general expert group, the owner unit and the scientific research team will make an evaluation.

Strugglers conform to the spirit of the times, which fully embodies the spirit of contemporary scientific and technological workers' continuous struggle and courage to climb the peak, and conforms to the image of "the most beautiful struggler" of China manned deep diving team. Therefore, the name of the all-sea deep-sea manned submersible was selected from the ten lists collected.
