Background
The hydropower station hydraulic power measuring system is mainly used for monitoring the upstream and downstream water levels of a hydropower station, the water level of a pressure regulating well and the accident water level in a factory building. The accident water level of the factory building is mainly caused after accident working conditions such as sudden burst of a large pipeline in the hydropower building, sudden burst of a top cover of a unit and the like occur. At this time, a large amount of water body floods into the factory building, and the existing drainage system of the factory building cannot timely drain the water leakage of the water body, so that the water level in the factory building continuously rises. When the accident happens, the rising speed of the water level in the factory building is very rapid, the accident working condition needs to be timely alarmed for ensuring the life safety of personnel in the factory building, the operation of the unit is timely stopped, and related emergency measures are started, so that the accident spreading and further expansion are prevented or delayed. Based on the above situation, a set of water-flooded plant alarm float switch is generally arranged at the lowest position of the plant and is used for alarming when a large amount of water leaks into the plant. At present, a float switch is generally arranged in a large sleeve, so that misoperation is easy to occur due to interference of other external factors, and regular inspection of an alarm device is also needed to be performed by manually changing the position of a float, so that the operation mechanism of the float switch is greatly different from that of a float under the working condition of an actual water flooding factory, and whether an alarm float is in a good standby state cannot be judged.
