Elevating jet fire trucks, forest fire isolation belt development vehicles, mudslides and landslide monitoring and early warning systems, high-rise building fire-fighting and rescue drones...

At the 2021 Changsha International Construction Machinery Exhibition, which opened on May 19, the Natural Disaster Prevention Technology and Equipment Innovation Exhibition in Hall E4 was quite eye-catching. More than 40 companies across the country brought hundreds of "unique weapons" in the field of natural disaster prevention and control to the exhibition, attracting waves of audiences and businessmen to stop to watch and negotiate.

Satellite remote sensing and drone detection make disaster relief and prevention more intelligent

"Like playing a game, press the forward button on the remote control, and the'pioneer robot' will run at full capacity. Weeds and shrubs will fall in pieces. Without the weeds and shrubs, the tiny pipes on the river embankment can be seen at a glance. In front of Zoomlion’s booth, Zhou Yuanzhen, deputy general manager of Zoomlion Emergency Equipment Co., Ltd., introduced to merchants that at the same time, a “pioneering robot” developed by Zoomlion can complete the workload of 20 people.

At this exhibition, Zoomlion also brought a series of "black technologies" in the field of natural disaster prevention: the world's first and highest large-span lift jet fire truck, multi-purpose forest fire isolation belt development vehicle, and emergency frame Bridge car...

Compared to the hundreds of square meters of booths of other companies, the booth of Hunan Beidou Microchip Industry Development Co., Ltd. (abbreviated as Beidou Microchip) is a bit small. However, there are more than 10 products on the long table that are put together in two pieces, but they are more conspicuous.

"Although the booth is small, our products have a lot of energy." said Peng Lingliang, the industry manager of Beidou Microchip. The Beidou high-precision ground disaster monitoring and early warning system developed by the company can issue early warnings before disasters occur through satellite remote sensing, and provide early warning for the masses. Safe transfers gain time. In July last year, the Beidou High-precision Earth Disaster Monitoring and Early Warning System successfully warned large-scale landslides in Shimen County, Changde City, and relocated 14 households with 33 people in advance, avoiding heavy casualties.

Today, drones are no longer a rarity, but the multi-wing drones placed in front of the booth of Hunan Huanuo Star Electronic Technology Co., Ltd. still attracted the attention of many audiences.

"This drone carries a two-dimensional positioning life detection radar. Whether it is at night or in severe weather such as rain or snow, it can penetrate ruins, floors and other collapsed buildings to locate multiple trapped targets." Hunan Huanuo Star Electronics Liang Tao, Director of Safety and Emergency Products of Technology Co., Ltd. warmly introduced to the audience.

At the exhibition of innovation achievements in natural disaster prevention technology and equipment, including China Aerospace Science and Industry Corporation, China North Industries Group, China Electronics Technology Group and other central enterprises, as well as well-known local enterprises in Hunan, displayed the company's scientific research results in natural disaster prevention technology and equipment. Promote the modernization of natural disaster prevention technology and equipment.

Hunan's disaster relief and prevention equipment industry develops rapidly

"Encourage enterprise research and development, strengthen the docking of production and demand. In recent years, Hunan's natural disaster prevention technology and equipment industry has developed rapidly." Huang Xuegong, chief engineer of the Provincial Department of Industry and Information Technology, introduced.

In 2019, Hunan established a joint meeting system for key projects to improve natural disaster prevention capabilities, with the governor serving as the convener; 23 provincial department heads as members, clarifying the list of tasks and responsibilities, and encouraging enterprises to carry out R&D and production. The provincial finance set aside 20-50 million yuan each year to support enterprises in developing natural disaster prevention and control technology and equipment.

Aiming at problems such as the mismatch between the R&D and production of natural disaster prevention technology and equipment, the adaptability of existing products, and the lack of practicability, Hunan has innovatively explored the method of "revealing the rankings", adopting a combination of "competition mechanism + post-subsidy + prepayment" to advance The engineering of natural disaster prevention and control work. According to the list of technical equipment requirements, a batch of engineering research projects are determined as the list tasks, and each task selects at most 3 unlisted units to form a competition mechanism to promote mutual "horse racing" among enterprises.

In June and December last year, Hunan organized more than 10 provincial departments and more than 20 enterprises in the province including emergency response, fire protection, water conservancy, natural resources and more than 20 enterprises in the advantageous fields of construction machinery, Beidou monitoring and early warning technology and equipment, and successively held two natural events. Disaster prevention technology and equipment production needs docking activities. Through the docking, some companies have obtained new orders, and some joint research projects have begun to take effect.

The multi-purpose forest fire isolation belt development vehicle jointly developed by Changsha Zhonglian Fire Protection Company and the Provincial Fire Rescue Corps has taken shape. The Provincial Emergency Management Department guided and supported the sand and gravel balers developed by Sany Group. The filling efficiency of a single unit is 60 times that of manual filling. Last year, the sand and gravel balers showed their talents in flood fighting in Hunan and Jiangxi.

Increase investment to encourage enterprise research and development; government-enterprise linkages to strengthen the docking of production and demand. Hunan's natural disaster prevention technology and equipment industry is developing rapidly. At present, Sany Group, Zoomlion, Sunward Intelligent and other enterprises have established emergency business departments, and more than 300 enterprises in the province are engaged in the research and development and production of natural disaster prevention technology and equipment.

Improve the disposal capacity, resolve major risks, and have broad prospects for people's livelihood projects

On May 19, the first time the exhibition was launched, Luo Luo, deputy secretary of the Party Committee and deputy director of the Provincial Emergency Management Department, came to the exhibition hall to observe the exhibition. As an "expert" in the field of natural disaster prevention, Rod Dragon admired: "The equipment on display has high technological content and strong practicability, which can greatly improve emergency response capabilities and resolve major hidden risks."

"Leveraging the advantages of Hunan's strong manufacturing province, forming a natural disaster prevention technology and equipment industrial cluster." Luoluo said that it is a trend to use scientific and technological equipment to improve emergency rescue and natural disaster prevention capabilities.

Feng Changgen, a professor at Beijing Institute of Technology, believes that advancing the modernization of natural disaster prevention technology and equipment not only conforms to the development of science and technology, but more importantly, it is a project for people’s livelihood and a great and powerful country when natural disasters occur. Mind, the future prospects are broad.

The R&D and production of natural disaster prevention technology and equipment has a promising future, and many companies have already keenly caught it. Zoomlion accelerates its deployment in the emergency industry with emerging technologies such as artificial intelligence, Internet of Things, and big data. In January of this year, Zoomlion established Zoomlion Emergency Equipment Co., Ltd. to specialize in the development and manufacture of six types of emergency equipment including fire rescue, water rescue, geological and meteorological disaster rescue, forest fire rescue, hazardous chemical accident rescue and logistics support.

"Promoting the modernization of natural disaster prevention technology and equipment is conducive to improving my country's natural disaster prevention and rescue capabilities, and creates a good environment for enterprises to develop and produce natural disaster prevention technology and equipment." Deputy General Manager of Zoomlion Emergency Equipment Co., Ltd. Zhou Yuanzhen said that enterprises should seize this opportunity, strengthen government-enterprise cooperation, and promote the R&D and production of natural disaster prevention technology and equipment.
