Description

A detection device for water conservancy engineering that is easy to observe the water level

technical field

The utility model relates to the technical field of water conservancy projects, in particular to a detection device for water conservancy projects which is convenient for observing the water level.

Background technique

Water conservancy project refers to the general term for a series of activities involved in water conservancy construction. In the construction of water conservancy projects, the water level of water conservancy should be detected, so as to understand the water level in time;

The announcement number is CN207248283U and the patent name is a water level detection device for water conservancy project management. Although the existing water level gauge is generally fixed in the river bed, the surface of the water level gauge is easy to be immersed in water for a long time. The adhesion of microorganisms such as moss makes it impossible to obtain the scale of the water level clearly, and due to the design characteristics of the water level gauge, it is very inconvenient to clean up, but the detection device only obtains the water level by reading the degrees on the water level gauge. The number of the upper degree is small, which is inconvenient for the staff to watch at a certain distance. At the same time, it is necessary to watch it horizontally, otherwise there will be certain errors;

We propose a detection device for water conservancy engineering that is convenient for observing the water level.
