This invention relates to the field of industrial safety monitoring equipment technology, and discloses an automatic overheat detection and alarm device for thermal power plants based on the principle of thermal expansion. The device includes a housing and a bimetallic strip. A vertical rod is slidably connected to the middle of the housing, and a horizontal plate is fixedly connected to the top of the vertical rod. An engaging assembly is disposed inside the housing, and the bimetallic strip is located in the middle of the engaging assembly. The bottom of the vertical rod contacts the top of the bimetallic strip. A visual warning assembly is disposed in the middle of the vertical rod, and an auditory warning assembly is disposed on the rear inner wall of the housing. The bimetallic strip deforms due to heat, pushing the vertical rod upwards, which causes a stop block to release the lock on the spring-loaded gear set, thereby releasing the stored energy of the spring to drive a hammer to continuously strike the warning bell. Simultaneously, a warning sign at the top of the vertical rod extends out of the housing, providing continuous audible and visual signals when overheating occurs, ensuring timely detection of hazards in the noisy environment of a thermal power plant.
