Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to a safety protection device for testing aircraft components. Background Art

[0002] Boeing737 is the most equipped aircraft in the history of human civil aviation. Its "heart" engine is known as the crown jewel of human industry. Civil aircraft engines are expensive and precise. It can provide the necessary power, gas and power for the aircraft. Similarly, APU is another important source of aircraft and power. In order to deal with emergencies, a fire extinguishing system is set up inside. The fire extinguishing systems of the aircraft engine and APU are set in extremely close positions. The B-737 aircraft body is relatively old. Its test architecture follows the design basis of the 1960s. The error-proof design used in the test process is implemented strictly according to the steps by formulating work cards and reference manuals. 737 is equipped with three fire extinguisher bottle handles with the same part number and the feel is exactly the same. The work pressure of aviation maintenance and maintenance is high, and the mental tension during the construction process is easy to cause human errors and false triggering. For example, if the left engine of the test aircraft presses the fire extinguishing handle and presses the APU test handle by mistake, it will cause huge losses to the aircraft. It is necessary to clean and replace the pipelines and check the core components of the aircraft, which will cause the aircraft AOG phenomenon.

[0003] For example, the Chinese patent publication number is CN214325402U, and the technical solution disclosed in the patent document is as follows: a B737 aircraft engine APU fire extinguisher bottle loop test protection device, including a vertical strip support plate, a control box, two longitudinal strip support plates, four strip protection baffles and an L-shaped handle bar; a display screen, a left engine fire extinguishing test button, an APU fire extinguishing test button, a right engine fire extinguishing test button, a test completion button and a power switch are arranged on the control box; a microprocessor, a memory, a power module and a four-way motor drive circuit are arranged in the control box.

[0004] The above technology utilizes the left engine fire extinguishing test button, APU fire extinguishing test button, and right engine fire extinguishing test button to control the strip protective baffle, and only opens the test area required for the current test each time, thereby effectively avoiding the false triggering of other fire extinguishing handles. However, it is inconvenient to protect the display screen, and the display screen is easily damaged by external force collision, resulting in high maintenance costs. Utility Model Content
