[0025] In the embodiment, the driving motor 28 drives the first bevel gear 29 to rotate, so that the plurality of second bevel gears 30 are synchronously rotated, the rotating angle of the rotating shaft 21 is changed, the sector leaf 6 is driven to rotate, when the engine is in a stationary state, the plurality of sector leaves 6 are driven to rotate to the state that the side surfaces are mutually attached, the function of preliminarily closing one end of the shell 1 is realized, some floating impurities (such as plastic bags) are prevented from being blown into the turbofan 3 together with the wind, and then the running state of the engine is affected, and the safety hazard is caused, so that the engine in the stationary state can be better protected, and foreign matters are prevented from entering the engine.
[0026] When the engine is normally rotating, at this time the delivery pump 35 pushes hydraulic oil into the storage cavity 11, the second bevel gear ring 13 gradually slides to one side of the first bevel gear ring 10, until the second bevel gear block is clamped with the first bevel gear ring 10, after that the rotating cylinder 5 cannot continue to rotate with the rotating of the turbofan 3, at the same time the first inclined surface 18 on the guide block 14 and the second inclined surface 19 on the block 16 will be in close contact during the sliding of the second bevel gear ring 13, gradually lifting the block 16, the first tension spring 17 is stretched, the block 16 gradually slides into the output groove 7, blocking the output groove 7, a sealing ring can be arranged around the block 16 to improve the sealing process of the output groove 7, after that the driving motor 28 adjusts the inclination angle of the plurality of fan-shaped leaves 6, so that the fan-shaped leaves 6 are limited when the air flow thrust is the smallest, at this time the resistance of the fan-shaped leaves 6 to the air flow is the smallest, and the air flow will be directly delivered to the turbofan 3 after passing through the fan-shaped leaves 6 to reach the inside of the engine, so that the input air flow is maximized, this scene is suitable for weather suitable and no obstacles, some large obstacles will be blocked by the fan-shaped leaves 6, to avoid directly entering the inside of the turbofan 3.
[0027] When the weather is abnormal and the impurities in the airflow are more, the fan-shaped leaf 6 is adjusted to the required inclination angle by the driving motor 28, and then the hydraulic oil in the storage cavity 11 is pumped out by the delivery pump 35, the second bevel gear ring 13 is driven by the second tension spring 37 to move away from the first bevel gear ring 10, gradually releasing the clamping and limiting of the first bevel gear ring 10, at the same time, under the pulling of the first tension spring 17, the block 16 slides reversely, so that the block 16 releases the blockage of the middle part of the output groove 7, and then in the process of rotating the turbofan 3, the input airflow will push the inclined surface of the fan-shaped leaf 6 to make the fan-shaped leaf 6 rotate the rotating cylinder 5 together, since the driving force of the fan-shaped leaf 6 is pushed by the airflow, most of the airflow entering the turbofan 3 will flow through the surface of the fan-shaped leaf 6, and after being guided by the guide groove 38, the rainwater and other impurities will be adsorbed in the guide groove 38 and thrown to the surrounding, then transported to the second annular groove 26 through the communication hole 27, and then transported to the output groove 7 through the first annular groove 25 for output, the outer end of the output groove 7 is connected with the outside, and the end is located in the arc region of the outer surface of the shell 1, the airflow outside the shell 1 will help to suck out the impurities in the output groove 7 and flow with the outside airflow in the process of flowing backward, thereby effectively avoiding the impurities entering the engine, and at the same time, since the inner opening of the communication hole 27 is larger than the outer opening, the airflow can more smoothly pass through the communication hole from the fan-shaped leaf 6 to the output groove 7, and the airflow in the output groove 7 is prevented from flowing reversely to the position of the fan-shaped leaf 6, and the auxiliary suction device 40 (such as a impeller rotating structure) can be arranged in the output groove 7 to improve the driving force of the airflow from the communication hole to the output groove 7, and the structure can be linked and controlled with the running state of the block 16 through a sensor or a control switch, so that when the block 16 moves up to block the output groove 7, the suction device 40 stops running, and when the block 16 moves down to open the communication state of the output groove 7, the suction device 40 starts to run at high speed, and the impurities at the communication hole 27 are sucked into the output groove 7 and discharged from the other end of the output groove 7.
[0028] It is worth noting that when encountering sand and dust weather, the aircraft needs to filter the solid particle impurities in the airflow during take-off and landing to avoid impurities entering the engine, the rotating net 33 is pushed out by controlling the electric telescopic rod 34, and the rotating net 33 is rotated to an angle perpendicular to the fan-shaped leaf 6, at this time, the gas flowing between the fan-shaped leaves 6 will be filtered by the rotating net 33, some relatively large sandstones are blocked, and in the process of rotation, the sandstones are thrown into the communication hole 27 by centrifugal force, and then discharged through the output groove 7, after use, the rotating net 33 is reversely turned over to the rotating groove 32 by the electric telescopic rod 34 for storage, the device has large resistance to airflow, and the engine speed needs to be increased during use to improve the thrust, which is only suitable for special weather use and plays an emergency role to avoid a large amount of impurities entering the engine and affecting the service life of the engine.
