A static pressure hole protection device used during airplane surface cleaning comprises a shielding assembly and a lifting assembly in butt joint with the shielding assembly. The shielding assembly comprises a blocking piece, a static pressure hole blocking piece is arranged in the center of the back face of the blocking piece, and suckers are arranged at the four corners of the back face of the blocking piece. A mounting base and an unlocking assembly are arranged on the front face of the blocking piece. The unlocking assembly comprises a support, a rotating shaft installed on the support and a rack located below the support, and the rack is meshed with a gear on the rotating shaft. One end of the rack is connected to the spring seat through a reset spring; the two ends of the rotating shaft are respectively provided with two T-shaped binding posts. The unlocking assembly further comprises pulleys arranged at the four corners of the blocking piece respectively, and an unlocking rope connected to the sucker unlocking connecting lug, the pulleys and the binding post. According to the device, the shielding assembly is lifted through the lifting assembly and adsorbed to the surface of the airplane through the suction cup, so that the static pressure hole blocking piece blocks the static pressure hole in the airplane, it is guaranteed that the static pressure hole is not blocked in the cleaning process, and the smooth surface around the static pressure hole is not scratched.
一种飞机表面清洗时用的静压孔保护装置,包括遮蔽组件和与其对接的举高组件。遮蔽组件包括一挡片,挡片背面中央设置静压孔堵片,挡片背面四角设置吸盘,吸盘上设置解锁接耳;挡片的正面设置有安装基座和解锁组件。解锁组件包括一支架、一安装在支架上的转轴及一位于支架下的齿条,齿条与转轴上的齿轮啮合;齿条一端通过复位弹簧连接到弹簧座;转轴两端还分别设置有两个T型的接线柱;解锁组件还包括有分别设置在挡片四角的滑轮,及连接在吸盘解锁接耳、滑轮和接线柱上的解锁绳。本装置通过举高组件将遮蔽组件举高,并用吸盘吸附在飞机表面上,使得静压孔堵片堵住飞机上的静压孔,保证在清洗过程中静压孔不堵塞也使静压孔周围光滑表面不会被划伤。
