DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-Figure 9 As shown, a highway maintenance intelligent inspection device includes a drone 1, and landing gears 2 are fixedly installed on both sides of the lower surface of the drone 1;

[0031] An electric gimbal 3 is fixedly mounted in the middle of the lower surface of the drone 1, and a camera 4 is mounted on the movable end of the electric gimbal 3;

[0032] Brackets 101 are fixedly installed on both sides of the lower surface of the drone 1, a rotating rod 5 is rotatably installed between the inner walls of the two brackets 101, a swing plate 6 is rotatably installed between the two swing plates 5, and a protective cover 7 is fixedly installed on the opposite side of the two swing plates 6.

[0033] The staff starts the drone 1 and then starts the electric pan-tilt platform 3, so that the camera 4 can take real-time photos of the highway, thereby achieving the purpose of inspection. When the drone 1 lands, the staff controls the two swing plates 6 to rotate based on the rotating rod 5. The rotating swing plates 6 drive the protective cover 7 to rotate based on the rotating rod 5. After the two protective covers 7 are attached to each other, they block the area around the camera 4, thereby protecting the camera 4 and preventing the camera 4 from being damaged by collision with foreign objects when the drone 1 lands.

[0034] In another embodiment of the utility model, one end of the two rotating rods 5 passes through the corresponding brackets 101 and is sleeved with gears 8;

[0035] A support plate 9 is fixedly installed on one side of the lower surface of the drone 1. A slide groove 10 is opened on the surface of the support plate 9 close to the gear 8. Two sliders 11 are slidably arranged in the slide groove 10. A rack 12 is fixedly installed on one side of the two sliders 11. The two racks 12 are respectively meshed with the corresponding gears 8.

[0036] A bidirectional screw rod 13 is rotatably installed between the two sides of the inner wall of the slide groove 10, and two sliders 11 are respectively threadedly arranged on the two sides of the rod body of the bidirectional screw rod 13;

[0037] A motor 14 is fixedly mounted on one side of the support plate 9 , and one end of the bidirectional screw rod 13 passes through the support plate 9 and is fixedly connected to the output shaft end of the motor 14 .

[0038] The staff starts the motor 14 so that its output shaft drives the bidirectional screw 13 to rotate. The rotating bidirectional screw 13 drives the two sliders 11 to move away from each other by screwing in the thread. Under the meshing action of the rack 12 and the gear 8, the rotating rod 5 drives the swing plate 6 and the protective cover 7 to swing, so that the protective cover 7 protects the camera 4.

[0039] In another embodiment of the utility model, a connecting plate 15 is fixedly installed on one side of the inner wall of the two protective covers 7, a connecting groove 16 is opened on the surface of the two connecting plates 15 close to the camera 4, a connecting block 17 is slidably arranged in the two connecting grooves 16, a semicircular plate 18 is fixedly installed on one side of the two connecting blocks 17, and a sponge plate 19 is fixedly installed on one side of the two semicircular plates 18.

[0040] When the protective cover 7 swings, the semicircular plate 18 drives the sponge plate 19 to swing along with the protective cover 7, so that the sponge plate 19 can clean the lens of the camera 4, and the staff does not need to clean it manually, thus reducing the workload of the staff.

[0041] In another embodiment of the utility model, a connecting ring 20 is sleeved on the outer wall of the camera 4, and the outer wall surface of the connecting ring 20 is set as an arc surface;

[0042] A spring 21 is disposed between the two connecting blocks 17 and one side of the inner wall of the corresponding connecting groove 16 .

[0043] Limiting grooves 22 are provided on both sides of the inner wall of the two connecting grooves 16 . A limiting block 23 is slidably arranged in each limiting groove 22 . The opposite sides of adjacent limiting blocks 23 are fixedly connected to the corresponding connecting blocks 17 .

[0044] When the semicircular plate 18 moves, the thrust of the outer wall of the connecting ring 20 drives the sponge plate 19 to move along the connecting groove 16, and the spring 21 is compressed, so that the sponge plate 19 can fit more closely with the lens, thereby increasing the friction between the sponge plate 19 and the lens, thereby enhancing the cleaning effect.

[0045] The working principle of this highway maintenance intelligent inspection equipment:

[0046] When in use, the staff starts the drone 1 and then starts the electric pan-tilt platform 3, so that the camera 4 can take real-time photos of the highway, thereby achieving the purpose of inspection. When the drone 1 lands, the staff controls the two swing plates 6 to rotate with the rotating rod 5 as the reference, and the rotating swing plates 6 drive the protective cover 7 to rotate with the rotating rod 5 as the reference. After the two protective covers 7 are attached to each other, the camera 4 is shielded, thereby protecting the camera 4 and preventing the camera 4 from being damaged by collision with foreign objects when the drone 1 lands.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
