Description

Water level measuring device for hydraulic engineering Technical Field The utility model relates to the technical field of hydraulic engineering, in particular to a water level measuring device for hydraulic engineering. Background The hydraulic engineering is a built engineering for controlling and allocating surface water and underground water in nature to achieve the aim of removing harm and benefiting. The water resource is developed, utilized, protected and managed by various facilities such as dams, embankments, sluice gates, pump stations, channels and the like. The utility model discloses a water level measuring device for hydraulic engineering, the bulletin number is CN222544787U, install the bottom plate seat on the platform earlier, the platform front side is the reservoir surface of water, float on the surface of water through the floater, utilize the water level to rise, the buoyancy of combining the floater on the surface of water promotes the hollow tube and reciprocates, the conducting bar is at the waist downthehole displacement, the pointer of conducting bar both sides will displace on the scale mark, indicate the water level height condition, in addition the conducting bar is at the waist downthehole displacement, the slider displacement in the box body of conducting bar body coupling, guarantee the conducting bar along with the smooth displacement of slider, prevent the jamming, the scale of L type scale board represents the safe water level simultaneously. This a water level measuring device for hydraulic engineering has simple structure, reasonable in design, and the thinking is novel unique, because damage appears easily in scale board, pointer and the hollow tube long-term use, inconvenient change alone it has increased follow-up maintenance cost, consequently we propose a measuring device of hydraulic engineering with water level. Disclosure of utility model In order to solve the technical problems, the utility model provides a water level measuring device for hydraulic engineering.
