Problems solved by technology
For civil aircraft, when it is parked at a civil airport, due to the interference of wind force and external manpower during the exhibition, it is easy to cause the breakage of the electrostatic discharger. On the one hand, it will endanger the safety performance of the aircraft during flight. Electrostatic dischargers are usually used as a set. When replacing, the entire electrostatic discharger on the wing of the aircraft needs to be replaced uniformly, which is costly and time-consuming

The invention relates to a protection device for an aircraft electrostatic discharger. The protection device comprises an inner tube (1) and an outer tube (2), wherein the inner tube (1) can move in the axial direction inside the outer tube (2); a first circumferential groove (3), a second circumferential groove (4) and a third circumferential groove (5) are sequentially arranged at intervals at the middle of the outer tube (2) from front to back; first axial grooves (6) are arranged between the first circumferential groove (3) and the second circumferential groove (4); and second axial grooves (7) are arranged between the second circumferential groove (4) and the third circumferential groove (5). The protection device is characterized in that first distance sensors (31), temperature sensors (41) and third distance sensors (51) are separately arranged in the circumferential direction in the first circumferential groove (3), the second circumferential groove (4) and the third circumferential groove (5), that height sensors (61) are arranged in the first axial grooves (6), and that wind speed sensors (71) are arranged in the second axial grooves (7). The protection device for the aircraft electrostatic discharger is simple in structure, convenient to operate, high in safety factor and good in protection effect.
Description
technical field [0001] The invention relates to a protection device, in particular to a protection device for an aircraft electrostatic discharger. Background technique [0002] The wing tips and trailing edges of aircraft wings, horizontal tails, and vertical tails are the easiest to accumulate electrostatic charges in a large area. Installing electrostatic dischargers on these parts can effectively reduce the corona threshold voltage on the surface of the aircraft body. The basic function of the discharger is It is to smoothly discharge the static charge on the body in a low-noise manner. For civil aircraft, when it is parked at a civil airport, due to the interference of wind force and external manpower during the exhibition, it is easy to cause the breakage of the electrostatic discharger. On the one hand, it will endanger the safety performance of the aircraft during flight. Electrostatic dischargers are usually used as a set. When replacing them, the entire electrosta...
