Problems solved by technology
[0002] The electric meter is an instrument used to measure electric energy. The electric meter is installed in the electric meter box. The current electric meter installation box can only realize the installation of the electric meter to prevent the electric meter from being exposed to the outer surface and being damaged. Once a fire occurs in the electric meter box and cannot be extinguished in time, it will Serious consequences are caused. Most of the meter boxes are installed in residential areas. The current meter installation box cannot protect the meter when high temperature occurs, which will damage the meter and cannot achieve overvoltage protection for the meter. Therefore, it is necessary Set a kind of ammeter installation box with safety protection function to improve the above problems

The invention relates to the related field of electric meters, in particular to an electric meter mounting box with a safety protection function. The electric meter mounting box comprises a box body and a first cavity fixedly formed in in the box body, wherein a driving shaft is rotatably mounted on the end wall of the upper side of the first cavity, and is in power connection with a main shaft ofa motor; the motor is fixedly installed on the upper side end wall of the first cavity; and the outer surface of the driving shaft is provided with a box body first transmission device used for transmission between the driving shaft and the rotating disc shaft. The electric meter mounting box with the safety protection function can detect a fire disaster, and can extinguish the fire in time whenthe fire disaster occurs, so as to protect electric meters, can detect the temperature, starts a fan device to perform cooling protection on the electric meters once high temperature occurs, can measure the electric quantity flowing through the electric meter, switches in an over-current protection block to protect the electric meters when the electric quantity is too large, and realizes control over all action processes through separation and reunion between shafts.
