On June 7, the 2023 China Water Expo and the 18th China (International) Water Summit Forum opened in Nanjing International Expo Center, Jiangsu Province. Peng Jing, Secretary of the Party Committee of IWHR, and Philip Guboville, Vice President of the Asian Water Council, attended the opening ceremony.
The opening ceremony of China Water Expo
China Institute of Water Resources and Hydropower Research (IWHR) has set up an 81 square meter themed exhibition hall at the Water Expo, which includes digital twin systems for water conservancy and hydropower engineering operation and maintenance, key technologies for intelligent construction of geotechnical engineering, hydraulic elevator dam, unmanned water quality monitoring ships, integrated and assembled in-situ ecological restoration equipment for lakes and reservoirs, underwater non-destructive testing robots, IoT intelligent water meters, ultrasonic intelligent water meters Multiple technologies and products such as TDU series intelligent multi-channel ultrasonic flow meters and intelligent water supply control platforms have been showcased. Through various forms such as display boards, videos, brochures, and interactive multimedia, the basic situation, advanced technological products, and significant technological achievements of the Chinese Academy of Water Sciences are vividly, vividly, comprehensively, and from multiple perspectives.
Theme exhibition hall of IWHR
This type of gate is a low head water retaining gate, which adopts an integral bottom hinge support combined with a small angle movement oil cylinder support. The hydraulic pump station provides power to drive the oil cylinder to expand and retract, causing the gate body to rotate around the bottom axis at a certain angle, achieving the functions of vertical gate water retaining and lowering gate water release. It is suitable for river landscape, irrigation and water storage, reservoir expansion, ecological water storage in rivers and lakes with a height of 1-5 meters, especially in mountainous areas with rising and falling floods and during ice periods.
At present, hydraulic elevator dam has been industrialized and widely used in countries such as China, Myanmar, Thailand, and Bangladesh.
Digital twin system for water conservancy and hydropower engineering operation and maintenance
We have established a three-dimensional geographic information model for the true topography of the watershed, which enables the display of water and rain information, hydroelectric dams, and public safety institutions, providing support for emergency command and decision-making in the watershed. This system has functions such as virtual roaming, virtual inspection, virtual operation, simulation training, 3D interactive operation and scoring, 3D interactive maintenance and assembly training assessment for water conservancy and hydropower equipment. It also integrates intelligent power plant construction content such as asset management, virtual electronic fence, robot inspection, and video linkage.
At present, the digital twin system for water conservancy and hydropower engineering operation and maintenance has become a demonstration achievement of intelligent construction in the industry, and has received widespread praise.
Based on information technology such as Beidou high-precision positioning technology, Internet of Things technology, and cloud computing technology, and utilizing the professional advantages of the Chinese Academy of Water Sciences, the system has developed key technologies for intelligent construction of geotechnical engineering, which can provide technical support and an intelligent and refined management platform for the safe construction and operation of water conservancy projects. This technology mainly includes intelligent monitoring of earthwork filling and excavation construction process, intelligent monitoring of underground tunnel construction process, intelligent monitoring of foundation treatment construction process, and water conservancy engineering safety monitoring system based on BIM+GIS.
At present, key technologies of geotechnical engineering intelligent construction have been successfully applied in projects such as Chushandian Reservoir, Altash Water Control Project, Qingyuan Pumped-storage hydroelectricity, Laos Nam Ngum 3 Hydropower Station, Beijing Xiongyang Intercity High speed Railway, etc.
Underwater non-destructive testing robot
This product is a cable based underwater robot equipment for visual and acoustic detection of long-distance pressurized water transmission pipelines and tunnels under water filling conditions. It is equipped with multiple sensing components such as inertial navigation, multi beam forward looking sonar, depth sensors, underwater cameras, Doppler velocimeters, and advanced integrated navigation positioning and motion control algorithms, which can achieve structural integrity detection under uninterrupted water supply, and have the ability to cross narrow spaces such as butterfly valves.
The intelligent water supply control platform is a visualization platform based on intelligent instruments and control terminals, integrating water quality improvement equipment, online monitoring equipment for water quality, water level, pipeline pressure, and metering equipment such as intelligent water meters and ultrasonic flow meters. This platform integrates data perception, remote diagnosis, intelligent decision-making, and online control to achieve real-time online monitoring and abnormal alarm of pressure, flow, and water quality during the water supply process from the source to the faucet. Data collection and control are carried out through the Internet of Things and wireless sensing technology, achieving remote automatic control of water intake and supply and intelligent management of rural water supply.
