Background Art
[0002] The hydrological and meteorological monitoring and reporting system uses advanced technologies such as telemetry, remote control, communication, computers and networks to automatically complete the real-time collection, transmission and processing of hydrological, meteorological, flood and construction information in the measurement area. With the development of society, the hydrological and meteorological monitoring and reporting system is not only used in traditional hydropower engineering and water resources management fields, but also widely used in environmental monitoring, ecological protection, urban planning and other fields. Through real-time monitoring and analysis of hydrological and meteorological data, it can provide important data support for environmental protection, disaster warning, urban planning, etc., which helps to optimize resource allocation, improve production efficiency, promote sustainable development, and effectively guide human production and life. However, the natural river channel has a large amount of sediment, and the pressure water level gauge is easily blocked by sediment, causing fluctuations in monitoring data, and it is inconvenient to handle during high water, and the operation and maintenance cost of the telemetering station is high. Summary of the invention
[0003] The utility model aims to solve the problem that the current pressure water level gauge is easily clogged by silt, causing fluctuations in monitoring data, inconvenient to handle during high water periods, and high operating and maintenance costs of telemetering stations. The utility model provides a protection device for pressure water level gauges that can effectively protect the pressure water level gauge and prevent it from being clogged by silt without affecting water level monitoring, thereby reducing the operating and maintenance costs of water level telemetering stations. The protection device can be widely used in natural river water level monitoring to prevent siltation.
[0004] The utility model discloses a protective device for a pressure water level gauge to prevent sedimentation. The characteristic of the protective device is that the protective device is a hollow steel pipe with an opening at the bottom. The lower section of the steel pipe is placed in a water body. A circular hole is arranged on the outer wall of the steel pipe in the water body. A grille is arranged at the opening at the bottom of the steel pipe. A pressure water level gauge is placed inside the steel pipe. The gap size of the grille is smaller than the outer diameter of the pressure water level gauge.
