Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project supervision devices, in particular to a dynamic supervision device for safe production of water conservancy projects. Background Technique

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits, and is also called a water project. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet the needs of humans; only by building water conservancy projects can water flow be controlled, flood disasters be prevented, and water volume be regulated and distributed to meet the needs of people's lives and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, channels, raft channels and fishways to achieve their governance goals.

[0003] In the monitoring and supervision work of water conservancy projects, especially in river waters with large water level changes, it is more necessary to monitor and measure the water level height in the area. However, most of the existing water level dynamic monitoring devices have complex structures and large volumes, which are not conducive to flexible placement and use. Content of the Utility Model

[0004] The purpose of this part is to outline some aspects of the implementation mode of the utility model and briefly introduce some preferred implementation modes. In this part, as well as in the abstract of the specification and the title of the utility model of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this part, the abstract of the specification and the title of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] Therefore, the purpose of the utility model is to provide a dynamic supervision device for safe production of water conservancy projects to solve the problems that most of the existing water level dynamic monitoring devices have complex structures and large volumes, which are not conducive to flexible placement and use as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A dynamic supervision device for safe production of water conservancy projects, which includes a positioning cylinder perpendicular to the water. Both sides of the positioning cylinder have water inlet grooves along its height direction. A floating ball block is arranged inside the water inlet groove. A guide rod is fixed at the top of the floating ball block and one end of the guide rod slides through the top of the positioning cylinder. A measuring frame is fixed at the upper end of the positioning cylinder, and a plurality of water level line trigger switches are uniformly arranged along the height direction on one side of the inner wall of the measuring frame. A trigger assembly is also arranged at the upper end of the guide rod and is matched with the water level line trigger switch. A control box electrically connected to the water level line trigger switch is also arranged at the inner top of the measuring frame.
