Abstract

The invention discloses a machine body pressure sensor protection cover which comprises an attachment device (1), two first sealing mechanisms (2), a pressing rod (3), a second sealing mechanism (4) and two supports (5). The attachment device (1) is fixed on the supports (5); the fixing rods (22) of the two first sealing mechanisms (2) distributed at the two ends respectively penetrate through themiddle holes of the supports (5); a sucking disc (24) is connected to the lower end of each fixing rod (22), a compression spring (23) is arranged between the supports (5) and the sucking disc (24),the sucking disc (24) of the second sealing mechanism (4) is connected to the lower end of the fixing rod (41), and the pressing rod (3) penetrates through center holes of the fixing rod (22) of the first sealing mechanisms and the fixing rod (41) of the second sealing mechanism and is fixed. The machine body pressure sensor protection cover is light in weight, small in size, convenient and reliable to install, long in service life and capable of being installed and fixed by effectively utilizing inner holes of onboard hexagon bolts.

Description

technical field [0001] The invention belongs to the technical field of protection of pressure-sensing holes on the surface of an aviation embedded air data sensor system, and in particular relates to a protective cover for a fuselage pressure sensor. Background technique [0002] The embedded air data sensor system solves atmospheric data by measuring the pressure distribution on the surface of the aircraft. The fuselage pressure sensor is an embedded air data sensor, which is distributed on the left and right sides of the front fuselage, conforms to the aircraft skin, and is used to measure atmospheric static pressure. There are 3 pressure measurement areas on the body pressure sensor, and each measurement area has 6 pressure-sensing holes of Φ1.8. The gas paths of the pressure-sensing holes are connected to each other and evenly distributed along the center circle of Φ10. When the aircraft is parked on the ground, it is necessary to protect the pressure sensing hole to pr...
