The shell 100 is used to install and place the DC metering controller body 110. When the temperature inside or outside the device is too high, the device can drive the rubber rod 220 and the impact ball 230 to rotate by rotating the rotating shaft 210, so that the impact ball 230 hits the copper tube 240 to generate an impact sound, thereby giving an alarm to the outside world. Temperature sensors 130 are fixedly installed on the upper end and the lower end of the outer wall of the cover plate 120, a spark sensor 140 is fixedly installed on the upper end of the outer wall of the cover plate 120, and a wireless transmission module 150 is fixedly installed on the right end of the outer wall of the shell 100. The two temperature sensors 130, the spark sensor 140 and the wireless transmission module 150 are all electrically connected to the DC metering controller body 110. The two temperature sensors 130 can monitor the temperature inside and outside the device, and the spark sensor 140 can monitor whether there is a flame in the external environment of the device. When the temperature inside and outside the device is too high or a flame is generated outside it, the device can send an alarm signal to the outside through the wireless transmission module 150. A connecting cylinder 300 is fixedly connected to the lower end of the inner wall of the installation frame 200, and a spring 310 is fixedly installed on the inner wall of the connecting cylinder 300. The lower end of the outer wall of the rotating shaft 210 passes through the upper side of the outer wall of the connecting cylinder 300 and is rotatably connected to the lower side of the inner wall of the connecting cylinder 300. The rotating shaft 210 is fixedly connected to the free end of the spring 310. A motor 320 is fixedly installed on the lower end of the outer wall of the cover plate 120. The output end of the motor 320 is fixedly connected to the lower end of the outer wall of the rotating shaft 210. A gear 330 is fixedly installed on the side wall of the rotating shaft 210 and located above the connecting cylinder 300. A block 340 that can slide back and forth is clamped in front of the gear 330. The starting of the motor 320 can drive the rotating shaft 210 to rotate, thereby driving the spring 310 to rotate and store energy. When the block 340 moves forward and disengages from the gear 330, the rotating shaft 210 will rotate driven by the spring 310.An L-shaped connecting block 400 is fixedly installed on the upper end of the outer wall of the mounting frame 200 and located in front of the outer wall of the connecting tube 300.

The conductive coil 520 is electrically connected to the DC metering controller body 110. By energizing the conductive coil 520, the iron core column 510 will generate magnetism, thereby attracting the armature piece 420 to slide backward, thereby driving the sliding rod 410 and the clamping block 340 to slide backward, allowing the clamping block 340 and the gear 330 to be clamped, thereby achieving the position fixation of the gear 330.

A spring 610 is fixedly installed symmetrically between the T-shaped connecting plate 600 and the armature piece 420. When the conductive coil 520 is powered off, the iron core column 510 will lose its magnetism. Under the action of the spring 610, the armature piece 420 will be pulled forward, thereby driving the sliding rod 410 and the clamping block 340 to slide forward.
[0032] Among them: first, the shell 100 is used to install and place the DC metering controller body 110. The motor 320 can be started to drive the shaft 210 to rotate, thereby driving the spring 310 to rotate and store energy, and then the conductive coil 520 is energized to make the iron core column 510 magnetic, thereby attracting the armature piece 420 to slide backward, thereby driving the sliding rod 410 and the block 340 to slide backward, allowing the block 340 and the gear 330 to be engaged, thereby fixing the position of the gear 330, and the two temperature sensors 130 can monitor the temperature inside and outside the device, and the spark sensor 140 can monitor whether there is a flame in the external environment of the device.

At the same time, the DC metering controller body 110 will cut off the power to the conductive coil 520. When the conductive coil 520 is powered off, the iron core column 510 will lose its magnetism. Under the action of the spring 610, the armature piece 420 will be pulled forward, thereby driving the sliding rod 410 and the block 340 to slide forward. When the block 340 moves forward and disengages from the gear 330, the shaft 210 will rotate driven by the spring 310. The device can drive the rubber rod 220 and the impact ball 230 to rotate through the rotation of the shaft 210, so that the impact ball 230 will collide with the copper tube 240 to produce a collision sound, thereby giving an alarm to the outside world.
