Wuhan laid-off workers' self-made submarines successfully performed underwater operations

Wuhan, May 8th: A submarine made by Zhang Wuyi, a laid-off worker from Wuhan, dives to the bottom of a 4.5-meter-deep pool on the 8th and succeeded in conducting underwater operations such as underwater fishing products and salvaged items.

Zhang Wuyi, 37, was originally a worker of a textile machinery factory in Wuhan. He had only a high school education, and once he was laid off, he opened a kiosk to spend his days. Inspired by Li Yuming, the first person of the Chinese private-owned submarine building in Caidian in Wuhan in 2008, Zhang Wuyi saw the idea of ​​creating a submarine for a small civilian submarine in China. Since then, he has borrowed more than RMB 3 million from his family and friends and embarked on a rough road to make submarines. So far he has built eight submarines one after another. The depth of the submarines can reach 50 meters to 100 meters. One of them sells one to a seafood farmer in Dalian for 200,000 yuan for the fishing of seafood products.

A silver-white submarine mooring pool of about 4 meters in length and more than 2 meters in width, this submarine operation experiment was carried out in a shipyard on the Changjiang River Beach of Wuhu Farm in Huangpi District of the city. The attraction included German television. More than 100 people, including Taiwan’s dozens of media, Zhang’s friends and relatives, and submarine customer representatives came to watch.

Zhang Wuyi said that in order to demonstrate to the outside world the submarine's underwater operation functions, he added submarines with manipulators, cameras, and other components. At the same time, it will spend 80,000 yuan to construct this pool, which is 15 meters long, 8 meters wide, and 4 meters deep, and needs at least 540 tons of water to demonstrate the demonstration effect. Due to the slow water injection rate, the submarine demonstration scheduled for May 1 was forced to be postponed for a week.

At about 10 o'clock in the morning, the demonstration of submarine underwater operation officially began. Zhang Wuyi drove the submarine to perform underwater operations. After submarines were inspected and warmed up, the submarine was formally launched at 10:22; 2 minutes later, the single-vehicle submarine driven by Zhang Wuyi began to dive slowly, and the center of the pool suddenly began to bubble up. Five minutes later, the on-site staff dropped five screwdrivers into the pool. At 10:41, the submarine finally surfaced to demonstrate that firecrackers were on the scene. Then Zhang Wuyi, who drilled the submarine, announced that he had succeeded in salvaging the seafood product previously placed in the pool and placing 5 screwdrivers in a container under the submarine.

Although the submarine underwater operation demonstration of self-made submarines was successful, Zhang Yiyi still has difficulty in excitement. He said that after many years of practice and improvement, the current manufacturing process and safety technology of self-manufactured submarines have been greatly improved under the guidance of experts. The market prospects of the products are broad, and orders can be overwhelmed. There are even many overseas orders, but the There is no technical standard for civilian submarines in the country, and its use is also subject to many restrictions. The fate of self-made submarines is still uncertain. (Finish)
