1. An explosion-proof dust of electromechanical level measuring device, including:
a explosion proof enclosure (100), provided with a partition plate (110), wherein two sides defined by the partition plate (110) in the explosion proof enclosure (100) being respectively formed as a safe chamber area (101) and a hazardous chamber area (102), and the partition plate (110) being provided with a power shaft sleeve (120) penetrating the partition plate (110) thereby communicating the safe chamber area (101) and the hazardous chamber area (102); a power unit (200), disposed inside the safe chamber area (101); a control module (300), disposed inside the safe chamber area (101), wherein the control module (300) is disposed adjacent to the power unit (200) and electrically connected to the power unit (200); a capstan (400), disposed inside the hazardous chamber area (102); a power shaft (500), sleeved in the power shaft sleeve (120), wherein two ends of the power shaft (500) are respectively connected to the power unit (200) and the capstan (400); and a pair of bearings (610, 620), disposed in the power shaft sleeve (120) and respectively sleeved with the power shaft (500), wherein the pair of the bearings (610, 620) are spaced with an interval thereby forming a fireproof path (601) between the two bearings (610, 620). |
