Under the restraining action of the lens protection frame 3, the protective cover 9 slides open on the top side of the lens protection frame 3. At the same time, the sliding of the protective cover 9 drives the fixed gear 11 to rotate. The rotation of the fixed gear 11 drives the threaded rod 12 to rotate on the fixing seat 13. The rotation of the threaded rod 12 causes the square block 14 to slide on the lens protection frame 3 under the restraint of the lens protection frame 3. The sliding of the square block 14 drives the brush plate 15 to slide on the lens, thereby completing the cleaning of the lens. When the cylinder shaft 5 retracts to the maximum limit, the protective cover 9 is just opened. At the same time, the brush plate 15 slides to the other side of the lens protection frame 3 without affecting the normal operation of the camera 2. When the drone lands, the cylinder 4 is activated to extend the cylinder shaft 5, and reset according to the above principle. When the sliding frame 7 slides to the same horizontal plane as the fixing seat 13, the torsion spring 16 resets the protective cover 9 and closes it to protect the lens. At the same time, due to the groove on the top side of the sliding frame 7, the normal operation of the fixed gear 11 is not affected, thereby increasing the practicality of the structure.

[0019] The utility model discloses a lens frame 3 is provided with fixed seat 13, and fixed seat 13 is provided with threaded rod 12, and threaded rod 12 is provided with square block 14, and square block 14 is provided with brush plate 15, and threaded rod 12 is provided with fixed gear 11, and fixed gear 11 is in contact with protective cover 9.

[0020] The utility model discloses a fixed seat 13 on the side close to fixed gear 11 is provided with rotating hole 20, and the fixed seat 13 on the side away from fixed gear 11 is provided with limiting hole 21, and one end of threaded rod 12 is rotatably installed in rotating hole 20, and the other end of threaded rod 12 is rotatably installed in limiting hole 21, and rotating hole 20 and limiting hole 21 cooperate with each other, so that threaded rod 12 can only rotate on fixed seat 13.

[0021] The utility model discloses that square block 14 is provided with threaded hole 19, and threaded rod 12 is screw -threaded in threaded hole 19, and through the setting of threaded hole 19, because square block 14 is in contact with lens frame 3, so that square block 14 can only slide on threaded rod 12 when threaded rod 12 rotates.

[0022] The utility model discloses that protective cover 9 is provided with clamping tooth groove 17, and fixed gear 11 is engaged with clamping tooth groove 17, and through the setting of clamping tooth groove 17, it is realized when protective cover 9 is slid on lens frame 3 and drives fixed gear 11 to rotate.

[0023] The utility model discloses that sliding frame 7 is provided with T -shaped groove 18, and T -shaped block 10 is slidably installed in T -shaped groove 18, and T -shaped groove 18 limits the movement of T -shaped block 10, and T -shaped block 10 can only slide in T -shaped groove 18.

[0024] The utility model discloses that fixed shaft 8 is fixedly sleeved with torsion spring 16, and torsion spring 16 is fixedly installed on protective cover 9, and through the setting of torsion spring 16, it is realized when sliding frame 7 slides to the same horizontal plane with fixed seat 13, and under the reset action of torsion spring 16, protective cover 9 resets and protects the lens.

[0025] The utility model discloses working principle:

[0026] When the UAV 1 lands and stops operating, the lens is protected by the protective cover 9. When taking off and patrolling, the cylinder 4 is started, and the cylinder 4 drives the cylinder shaft 5 to retract. The retraction of the cylinder shaft 5 drives the sliding frame 7 to slide on the T-block 10. The sliding frame 7 drives the fixed shaft 8 to slide. The sliding of the fixed shaft 8 drives the protective cover 9 to move. When the sliding frame 7 slides to the same horizontal plane as the lens protection frame 3, the sliding frame 7 continues to slide. Under the limiting action of the lens protection frame 3, the protective cover 9 slides open on the top side of the lens protection frame 3. At the same time, the sliding of the protective cover 9 drives the fixed gear 11 to rotate. The rotation of the fixed gear 11 drives the threaded rod 12 to rotate on the fixed seat 13. The rotation of the threaded rod 12 makes the square block 14 slides on the lens protection frame 3 under the limit of the lens protection frame 3, and the sliding of the square block 14 drives the brush plate 15 to slide on the lens, thereby completing the cleaning of the lens. When the cylinder shaft 5 shrinks to the maximum limit, the protective cover 9 is just opened, and at the same time, the brush plate 15 slides to the other side of the lens protection frame 3 without affecting the normal operation of the camera 2. When the UAV lands, the cylinder 4 is started to drive the cylinder shaft 5 to extend and reset according to the above principle. When the sliding frame 7 slides to the same horizontal plane as the fixed seat 13, the protective cover 9 is driven to close under the reset action of the torsion spring 16 to protect the lens. At the same time, since the top side of the sliding frame 7 is provided with a groove, it does not affect the normal operation of the fixed gear 11, thereby increasing the practicality of the structure. During this process, the rotating hole 20 and the limiting hole 21 cooperate with each other, so that the threaded rod 12 can only rotate on the fixed seat 13. Through the setting of the threaded hole 19, since the square block 14 is in contact with the lens protection frame 3, the square block 14 can only slide on the threaded rod 12 when the threaded rod 12 rotates. Through the setting of the tooth groove 17, the fixed gear 11 is driven to rotate when the protective cover 9 slides on the lens protection frame 3. The T-slot 18 limits the movement of the T-block 10, and the T-block 10 can only slide in the T-slot 18. Through the setting of the torsion spring 16, when the sliding frame 7 slides to the same horizontal plane as the fixed seat 13, the protective cover 9 is driven to reset under the reset action of the torsion spring 16 to protect the lens.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
