This year's No. 9 typhoon "Canhong" landed on the coasts of Zhejiang Province and Nantong, Jiangsu on July 10 and July 11, 2015, respectively. The intensity has been strengthened to a super typhoon, and it is the strongest typhoon that has landed in Zhejiang in July in 60 years. The lowest pressure near the center is 925 hPa, and the maximum wind force is 17 (58 m/s). There are many wind power projects where Jiangsu Haili Wind Power Equipment Technology Co., Ltd. (hereinafter referred to as “Jiangsu Haili”) provides supporting equipment at the transit area of ​​“Canhong”. In Zhejiang, there are China Power Construction Haiyan, Zhongying Fuquan Mountain, Zhejiang Donghaide Jia, Longyuan Zhoushan Jintang, Zhejiang Shipu Tantoushan Island and other projects have successively equipped wind turbine towers for 0.85MW, 1.5MW, 2MW and 2.5MW units. The maximum diameter of these towers is 4.7 meters and the highest reaches 90 m; in Nantong, Jiangsu, the 2.38MW, 4MW, 5MW, 5.5MW, 6MW and other units of the Longyuan Offshore Wind Farm have been equipped with jacket foundation bearing platforms and their towers successively. The distance between these wind farms and the typhoon landing site is 100 meters. Within kilometers, it is the first time for "Haili" wind power supporting equipment to meet the typhoon at such a close distance. All the supporting products of Jiangsu Haili ensure the normal operation of the wind turbines it supports after the typhoon. The "Haili" brand wind turbine tower and offshore pile foundation The anti-typhoon performance of the platform products has been best verified in this typhoon attack.

 

During the production process, Jiangsu Haili has different requirements for wind resistance of wind power pile foundations and other bearing equipment according to onshore wind power, offshore wind power and offshore wind power units. They invest more in technical standards, material selection, welding process and other links. With more capital and manpower, by improving inspection standards and increasing inspection links, all products fully meet the requirements in terms of verticality, coaxiality and flatness, thereby enhancing the stability and wind resistance of products; they improve the industrial chain at the same time. It pays attention to the R&D and production of high-quality products, and its corrosion resistance, wind resistance, lightning protection, shock resistance and many other functions are reflected in the supporting equipment produced, and good results have been achieved.

 

So far, Jiangsu Haili has 2 invention patents and 30 utility model patents; in 2012, it was recognized as a national high-tech enterprise, and it is the project establishment unit of the National Small and Medium Enterprise Innovation Fund Project and the project implementation unit of Jiangsu Province Industrial Science and Technology Support Plan. Wind turbine foundation 2MW-5MW high-power offshore wind power jacket bearing platform products and 2-6MW wind turbine towers were awarded the high-tech product certificate of Jiangsu Province in 2010, 2013 and 2014 respectively, and won the third prize of Nantong City Science Progress Award in 2012 In 2014, it won the third prize of Jiangsu Province Science Progress Award. It is a national key new product and the first (set) major equipment product in Jiangsu Province.
