| description | The invention discloses a grounding device for an airport ground power van. The grounding device comprises a direct-current motor, a rack, a pressure sensor signal line, a grounding line, a direct-current contactor, an ampere meter, a storage battery, a detection line, a connecting rod, a spring, a detection plate, a position switch, a movable grounding plate, a fixed grounding plate, a pressure sensor, a bonding pad and a guide rail. An original power van grounding electrode is changed into the movable grounding plate, the problem that the power van grounding electrode cannot be grounded on the hardened ground of an airport is solved, the contact area is increased, the grounding resistance is reduced, and the guarantee safety is improved. The ground state of the airport ground power van can be detected, the detection result serves as one of locking conditions for starting of the power van, grounding locking is achieved, the situation that an operator forgets to place a movable grounding plate or starts the p |
