[0034] Reference Figures 1-7 ;
[0035] Inside the protective cover 1, a protection component 6 is installed. The protection component 6 includes a button switch 601 which is installed on the outer surface of the electronic component body 3. The protection component 6 also includes a hydraulic rod 602 which is arranged inside the protective cover 1. The output end of the hydraulic rod 602 is fixedly connected with a moving block 603. By setting the button switch 601, the switch of the electronic component body 3 can be controlled, and thus the normal use of the device can be ensured subsequently. The protection component 6 also includes a protective shell 604 which is installed on the upper surface of the protective cover 1. Inside the protective shell 604, a collecting roller 605 is rotatably connected. The arranged collecting roller 605 can realize the collection of the cable, thus facilitating the subsequent use work.

A connecting rope 615 is wound around the outer surface of the collecting roller 605, and the connecting rope 615 passes through the through hole 614 and extends above the inclined plate 613. The bottom surface of the connecting rope 615 is fixedly connected with a connecting block 616, and the bottom surface of the connecting block 616 is fixedly connected with the upper surface of the inclined plate 613. By rotating the collecting roller 605, the change of the inclination angle of the inclined plate 613 can be realized, and thus the leakage of dry powder can be realized, avoiding the increase of the fire.
[0039] The specific working principle of the present invention is as follows:
[0040] During use, when the set current threshold exceeds the set current, first, the single-chip microcomputer 35 will immediately send a working signal to the hydraulic rod 602 and the first electric push rod 609. The output end of the hydraulic rod 602 starts to drive the moving block 603 to move downward. When it contacts the button switch 601, the closing of the electronic component body 3 is realized. Then, the output end of the first electric push rod 609 starts to contract, releasing the limit on the round rod 607. By using the pressure of the dry powder on the inclined plate 613, the collecting roller 605 starts to turn over, so that the rope wound around the surface of the collecting roller 605 can be pulled out. While pulling out, the angle of inclination of the inclined plate 613 will gradually increase, and then the leakage of the dry powder can be realized, making it impossible for the electronic component body 3 to catch fire in the future. The timely power-off of this device is realized, avoiding the problems of equipment damage and fire.
