[0002] The helicopter mainly provides the lift source through the main paddle, provides the lift required for flight, simultaneously provides the control force required for flight, balances the counter torque of main rotor through the tail paddle, and realizes the heading control of the helicopter, realizes the stabilizing effect on the heading of the helicopter. The pilot only needs to use very small force to make the control rod move a very short distance in the cockpit through the internal control system, and the paddle can be controlled, wherein the booster is a key part of the control system.

[0003] The booster is a mechanical position servo power amplifier, and the inside of the booster drives the control surface through the hydraulic oil pressure to output a large force. The movement of the main paddle and the tail paddle is controlled. If the booster is to be stably used, the inside of the hydraulic oil must be pure and cannot be mixed with impurities. If impurities exist in the inside of the hydraulic oil, the booster will be damaged during control, and other adverse effects will occur. The hydraulic oil filter in the inside of the booster mainly plays a role in filtering the impurities in the hydraulic oil, so cleaning the hydraulic oil filter is a key step to ensure the purity of the hydraulic oil.

[0004] At the present stage, during the periodical inspection of the aircraft, six hydraulic oil filters in the main booster and two hydraulic oil filters in the tail booster need to be disassembled and cleaned.

During the cleaning, the marked hydraulic oil filters are placed in plastic bags and transported to the ultrasonic cleaning machine, and the hydraulic oil filters are turned over to realize sufficient cleaning. The whole marking and cleaning process has the defects of time-consuming and labor-consuming, low cleaning efficiency and easy marking loss during cleaning. UTILITY MODEL CONTENTS
