[0032] Working principle: During operation, the position of the first rotating rod 13 can be fixed by the wax block 14. When the charging pile body 1 catches fire, the wax block 14 will melt and contact the fixed state of the first rotating rod 13, and the first rotating rod 13 will fall. The pull wire 108 is pulled by the first fixed block 16 to make the turntable 101 rotate continuously. The alarm bell 106 is knocked by the first pull rope 102 and the knocking ball 103, so that the alarm bell 106 continuously sends out an alarm sound to warn the people around. The position of the second fixed rod 21 can be stabilized by the wax block 14. When the charging pile body 1 catches fire and generates high temperature, the wax block 14 will melt and the second fixed rod 21 will flip downward, so that the first fireproof plate 22 will cover the fire part of the charging pile body 1 to prevent it from open flames. The fire can be spread, reducing the oxygen inside the fire site, avoiding the spread of smoke and affecting the surrounding people to stay away from the scene. The second pull rope 3 and the counterweight 31 can make the first rotating rod 13 and the second fixed rod 21 fall faster. The spring 4 can make the rubber rod 105 shake repeatedly when the knocking ball 103 knocks the alarm bell 106, thereby extending the alarm time of the alarm bell 106. The shrapnel 5 and the second fireproof plate 51 can be used to make the fire site of the charging pile body 1 closer to the fire site of the charging pile body 1 by utilizing the elastic force of the shrapnel 5, thereby reducing the oxygen content in the fire site.
