Explosion-proof 3D grain reserve monitoring device

The utility model discloses an explosion-proof type 3D grain reserve monitoring device which comprises a lifting frame, a shell is rotatably arranged at the lower end of the lifting frame, a monitoring instrument is arranged at the lower end of the shell, and the explosion-proof type 3D grain reserve monitoring device further comprises a driving assembly which is arranged in the shell and used for driving the shell to rotate relative to the lifting frame. And the slip ring is arranged in the shell, is electrically connected with an external power supply to supply power to the driving assembly, and rotates along with the shell. According to the utility model, the slip ring is connected with the external power supply and can rotate along with the shell, so that when the driving assembly drives the shell to horizontally rotate relative to the hoisting frame, the slip ring also rotates along with the shell, and the wire which is connected between the slip ring and the driving assembly and is used for supplying po
