In addition, a knocking mechanism is arranged on the inner wall of the air outlet channel, and a corresponding impact rod is arranged on the rotating shaft. The impact rod periodically hits the sliding pin in the knocking mechanism. The sliding pin converts the lateral thrust into an upward thrust through the inclined block, thereby pushing the impact pin to hit the protective net and making a sound at the same time, thereby preventing birds from staying or nesting on the top of the power meter box, thereby preventing excrement from entering the inside of the power meter box. Secondly, by arranging a fire-fighting sealing mechanism on the inner side of the power meter box and at the air inlet, when a fire occurs in the power meter box and the heat rises greatly, the kerosene glass tube shatters, thereby removing the supporting force on the push-down frame. Then, under the action of the spring, the push-down frame and the linkage plate rise, and the rack on the linkage plate can drive the sealing plate to rotate by cooperating with the gear, and then the air inlet is blocked. At the same time, the fan blades continue to exhaust the power meter box, so that the power meter box is in a relatively vacuum state, thereby preventing the fire from further expanding.
