With the help of unmanned aerial vehicles to simplify water conservancy project inspections, inject modern inspection methods, improve work efficiency, improve overall supervision capabilities, and add new vitality to the water conservancy engineering industry.
Why Carry Out Drone Water Conservancy Inspections?
Water conservancy inspection is a complex and tedious task with a vast inspection area and high costs. Relying on modern technical means, the drone is equipped with optical, radar and other sensor equipment to accurately measure and record water flow velocity and water depth data. Production provides an important basis.
Application Scenarios of drone Water Conservancy Inspection
River and lake monitoring and regulation
Drones can be used to assist in the monitoring of suspected illegal buildings, illegal planting and development and utilization, and illegal sand mining within the jurisdiction of water conservancy projects, extract information such as the location and scope of illegal acts, and provide technical support for water law enforcement management. Violations of laws and regulations should be detected early, stopped and dealt with early.
Soil and Water Conservation Survey
The traditional soil and water conservation monitoring technology cannot meet the requirements of accuracy, timeliness and completeness in production and construction projects. The low-altitude remote sensing of drones has the characteristics of high precision, strong timeliness, and high degree of visualization. It can be used for quantitative detection and evaluation of water and soil loss, monitoring and evaluation of water and soil conservation control measures, and water and soil conservation monitoring of production and construction projects. Drone monitoring has become a new technical means for comprehensive monitoring of soil and water conservation.
Flood and Drought Disaster Prevention
Drone systems play an important role in flood control, drought resistance, and disaster relief, and can be used for emergency monitoring of landslides, mountain torrents, urban floods, and dam collapses. The maneuverability and flexibility of the drone system are especially suitable for emergency response, which greatly reduces the risk of emergency personnel and improves the efficiency of early warning and disaster handling. Quickly and accurately conduct aerial photography and loss assessment of the disaster-affected area, providing rescuers with valuable first-hand information.
Water conservancy inspection
Drones can quickly monitor the water conservancy projects that need to be inspected in real time, and can also grasp the relevant hydrological conditions such as land submersion caused by the construction of hydraulic structures through real-time inspections of upstream and downstream rivers. The comprehensive use of monitoring data analysis results obtained by drones can effectively monitor temporary buildings such as cofferdams, check the safety status of surrounding slopes, and investigate the type and quantity of submerged land. Find relevant signs in time to prevent accidents and ensure the smooth progress of hydraulic structure construction. At the same time, provide information for controlling construction quality, reducing impact on surrounding environment, and improving construction methods.
Emergency monitoring of barrier lake
Barrier lakes are formed by landslides and landslides caused by landslides or landslides caused by debris flow or seismic activity, etc., blocking river valleys or riverbeds and storing water. The formation scale and environment of barrier lakes are complex, and because the blockages are vulnerable to erosion and erosion, once they are destroyed, it is easy to form secondary disasters with serious consequences. Due to the technical characteristics of drones such as small size, flexibility, fast maneuverability, and simple maintenance and operation, it can provide efficient on-site investigation and evaluation and dynamic early warning for the distribution and dynamic changes of barrier lakes. To provide first-hand information and scientific decision-making basis for experts to judge the nature of the barrier lake and assess the risk, to conduct preliminary research and scale estimation for the barrier lake collapse plan and the disaster plan for the resettlement of downstream dangerous areas, and for the barrier lake Carry out timely monitoring and early warning for risk elimination and collapse.
Ice Emergency Monitoring
The traditional method of estimating ice hazards by human eyes mainly relies on experience. Although it is simple and reliable, the observation range is small, and it lacks information on the ice hazards of the entire river. Satellite or aerial remote sensing detection methods have a large observation range and wide coverage. However, due to the long revisit cycle of satellites, low resolution of remote sensing, and vulnerability to atmospheric interference, the ability to grasp local details of rivers is not strong, and the real-time performance does not meet the requirements. Drones for environmental monitoring and disaster assessment have mature applications and practices in many fields. The drone is equipped with various high-performance sensors, which can remotely monitor the distribution of river openings, ice plugs, ice piles, ice dams, etc., and provide a scientific basis for judging the scale and severity of ice disasters.
