Description

Technical Field

[0002] In water conservancy projects, various countermeasures and measures are studied and taken according to the laws and characteristics of floods to prevent or mitigate flood disasters and ensure water conservancy work for social and economic development. Its basic work content includes flood control planning, flood control construction, flood scheduling and arrangement, post-disaster recovery and reconstruction, etc. Flood control measures include engineering measures and non-engineering measures. Flood control is also an important professional discipline in water conservancy science. Therefore, water level monitoring devices are indispensable for water conservancy projects.

[0003] The existing water level monitoring device for water conservancy projects is achieved by placing a floating detector on the water surface or placing a monitoring rod with a scale in the water body. The method of placing a monitoring rod in the water body to monitor the water level requires manual placement near the monitoring rod to observe the water level, which is more troublesome. When a floating detector is used to monitor the water level, if the floating detector is small in size, it is easily affected by the fluidity of the water surface and has a small buoyancy. If floating objects are placed on the detector due to the action of waves, it is easy to cause the detector to be placed below the water surface. If the floating detector is large in size, floating objects such as water plants are easily retained on its surface, causing the detection line of the detector to be below the water surface, resulting in inaccurate water level monitoring.
