Domestic joints of China "Underwater Great Wall"

Domestic joints of China "Underwater Great Wall"

The deeper the water, the greater the water pressure, so the equipment that completes technical work in deep water needs a very high level of technology.

However, with the rapid development of science and technology in China, the market monopoly of foreign products has been broken, and China has developed a new high-tech product, which can work normally under two kilometers of water.

This new high-tech product is a 2000m underwater plug-in electrical connector developed by China Zhongtian Technology.

Zhongtian Technology's 2000-meter underwater plug-in electrical connector project has passed the new product appraisal.

So what does it do? If the underwater optical cable, cable and other cables are compared to the arms and legs of various submarine observation platforms, then the underwater connector is like a joint, which is one of the important components to ensure the normal work of underwater equipment.

With the birth of this product, China's "Underwater Great Wall" finally has a domestic joint.

It is understood that the plugging and unplugging of underwater connectors needs to be completed directly under water. This scientific and technological achievement is widely used in submarine observation network, offshore oil production platform, underwater construction machinery, underwater power distribution system and other fields.

It faces two problems, on the one hand, it needs to meet the sealing requirements in the inserted state, on the other hand, it needs to meet the sealing requirements in the dynamic state.

In other words, when the pin is not inserted, the seal needs to be closed, and when the pin is inserted and inserted in place, the seal needs to be maintained.

However, in thousands of meters of water where it needs to work, both the "piston" and the "pipe wall" are easy to deform under huge underwater pressure, and the pressure difference caused by underwater pressure will make it difficult to pull out the connector.

Therefore, the technical and technological difficulty of plugging and unplugging underwater connectors is very great.

It's so difficult to manufacture, but underwater equipment needs this, and the whole world has to develop this product.

Since 1980s, underwater connectors have been applied and developed, but at that time, the domestic underwater connector market in China was completely monopolized by foreign countries.

With the support of the state and the efforts of relevant researchers, China has broken the monopoly of foreign countries, and successfully completed the development plan of 4-core underwater plug-in connector according to the development plan of self-raised funds and independent projects of Chinese enterprises.

A large number of key technologies have been broken through, including plug and socket longitudinal sealing technology, underwater dynamic plugging and unplugging sealing technology and electrical insulation technology, and a series of technical platforms needed for research and development have also been established.

The product has passed the third-party full performance test, and has undergone many lake tests and sea tests, and can work normally under water for two kilometers.

China's product appraisal experts gave a very high evaluation of this product, believing that its performance and indicators are at the leading level in China, which is not inferior to imported products at all, and calling for its popularization and application in related fields as soon as possible to meet the needs of China's marine development.

This is not the first time that 20 19 China has broken foreign monopoly. The glass substrate can be applied to production and operation data and advanced computer technologies such as big data, cloud computing and artificial intelligence. Its first production line project, the 8.5-generation TFT-LCD glass substrate produced in China, also held a groundbreaking ceremony.

This product is also subject to foreign technology, but with the independent innovation of China scientists for three years, it has successfully achieved a "zero" breakthrough.

With the development of science and technology in China, there will be more and more such things. The scientific and technological strength made in China will become stronger and stronger, and so will the national strength of China.
