Description

Technical Field

[0001] The present application relates to the technical field of sound and light alarms, and more specifically, to a fire monitoring and alarm device for a hydropower station. Background Art

[0002] A hydropower station is a comprehensive engineering facility that can convert water energy into electrical energy. It generally includes a reservoir formed by water retaining and water discharge structures, a water diversion system for a hydropower station, a power plant, and electromechanical equipment. The high water level of the reservoir flows into the plant through the water diversion system to drive the turbine generator set to generate electricity, and then enters the power grid through the step-up transformer, switch station and transmission line. There are many electrical equipment in the hydropower plant and the room structure is complicated. Once a fire occurs, people who are not familiar with the structural layout of the plant are easily lost and trapped indoors in an emergency. If people are trapped indoors and cannot notify outsiders for rescue, the rescue efficiency of firefighters and the survival rate of trapped people will be reduced.

[0003] Patent No. CN217061137U discloses an indoor sound and light alarm, including a base plate and a support column arranged on the base plate, a support plate is installed on the support column, a sound and light alarm is installed at the center position of the top of the support plate, a protective component is installed on the support plate, and the sound and light alarm is located inside the protective component. The protective component includes a protective cover and a fixed block arranged at the bottom of the protective cover, a through hole is opened on the side wall of the protective cover, the protective cover is sleeved on the outside of the sound and light alarm, a telescopic tube is installed at the bottom of the fixed block, a spring is arranged on the side wall of the telescopic tube, a limit block is installed at the bottom of the telescopic tube, a threaded rod is installed at the bottom of the limit block, the bottom end of the threaded rod passes through the support plate, a nut is arranged on the side wall of the threaded rod, and the top of the nut is in contact with the bottom of the support plate. By setting the protective component, the sound and light alarm can be effectively protected.
