Description

Technical Field

[0001] The utility model relates to the technical field of hydrological monitoring, in particular to a surface water volume monitoring device. Background Art

[0002] Surface water monitoring equipment refers to special equipment used to monitor the water quality and hydrological characteristics of natural water bodies (such as rivers, lakes, etc.). These devices use advanced sensor technology and monitoring devices to collect key data such as water quality, water volume, and water flow rate in real time, providing important support for environmental monitoring, water resources management, and ecological protection;

[0003] Existing water volume monitoring devices usually use radar water level meters for water volume monitoring. Radar water level meters are non-contact measuring instruments that are suitable for long-distance water level measurement and are therefore widely used in the water conservancy industry.

[0004] It has been found in actual use that this type of water volume monitoring device has the following shortcomings:

[0005] The installation position is fixed, and the distance the radar water level meter extends outward from the crossbar is fixed and cannot be adjusted during installation. In the dry season or when the installation position is far away, the riverbed within the radar measurement range is exposed, affecting the accuracy of monitoring;

[0006] There are some interference factors in the radar water level meter that make the measurement of the radar water level meter not so accurate and cause errors. It can only measure the distance of the measured object, but cannot distinguish whether the measured object is the water surface. Generally, the water surface is not static and will fluctuate. The objects that interfere with the measurement are mostly solid and have no fluctuations on the surface. When other objects enter the radar measurement range, it will affect the measurement results;

[0007] Therefore, the present application provides a surface water volume monitoring device to meet the needs. Utility Model Content

When in use, the position of the radar water level meter can be adjusted according to the riverbed conditions, making monitoring more flexible;

[0021] 2. The ring-shaped calibration float can not only be used as a calibration object, but also as a floating object that can block the water flow and resist interference. The calibration float can be placed below the radar water level meter and float on the water surface with the fluctuations on the water surface. The reflectivity of the water surface is used to determine whether the radar water level meter monitors the water surface.
