The hydrodynamic automatic flood prevention device independently developed by Nanjing Junli Technology Co., Ltd. has successfully passed the evaluation and application for autonomous equipment of China’s urban rail transit, and has been invited to participate in the Second China Urban Rail Transit Equipment Independent Innovation Achievement Exhibition.
With the theme of “Green and Intelligent Rail Transit, Innovative Industry, and Stepping towards High-quality and Leapfrog Development of Rail Transit”, this exhibition, relying on the high-tech and rail transit industry characteristics of the Guangdong-Hong Kong-Macao Greater Bay Area, has gathered more than 300 industry experts and over 6,000 participants. They discussed the high-quality development of the industry at the main forums and sub-forums organized by the conference.
The hydrodynamic automatic flood prevention device developed by Nanjing Junli Technology Co., Ltd. has complete independent intellectual property rights. The product technology has obtained more than 40 Chinese certificates, including more than a dozen invention certificates, and has also been authorized with certificates in the United States, Japan, the United Kingdom, South Korea, Australia, Canada, and the European Union. At the same time, the product has also won the Special Commendation Gold Award at the Geneva International Invention Exhibition, the Gold Award at the 10th China International Invention Exhibition, and the Excellent Certificate Award in Jiangsu Province.
The company’s products have been applied in batches in the subways of more than a dozen cities, including Beijing, Guangzhou, Nanjing, Hong Kong, Suzhou, Chongqing, Shenyang, Dalian, Qingdao, Shijiazhuang, and Nanchang. As an excellent case of autonomous innovation achievements in urban rail transit, Junli will surely make greater contributions in the field of rail transit.
Du Qinghua, Deputy General Manager of the Rail Transit Business Department, gave a keynote speech at the company.
The hydrodynamic automatic flood prevention device realizes automatic opening and closing of water blocking by using the principle of water buoyancy. It has no power drive, requires no personnel on duty, has a reasonable structural design, is convenient for installation and maintenance, has reliable product performance, and has features such as anti-collision warning, meeting the market demand for fully automatic water blocking and preventing backflow at the entrances and exits of rail transit systems.
In order to boost the vigorous development of China’s rail transit industry, Nanjing Junli will continue to take independent innovation as the leading factor, focus on the main development lines of the industry, namely intelligence, greenness, and informatization, and continue to develop products and system solutions that meet the development needs of the rail transit industry, making contributions to the leapfrog and high-quality development of China’s rail transit.
