[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are one embodiment of this invention, and not all embodiments. Based on the described embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0031] This embodiment provides a camera rotation adjustment device for an inspection robot.

[0032] Reference Figures 1-3 A camera rotation adjustment device for an inspection robot includes a robot body 1, a camera body 2, and a camera rotation platform 3. The robot body 1 is a mobile chassis structure, integrating a chassis drive motor, an information receiving and processing device, a battery, and a control module, enabling autonomous or remotely controlled mobile inspection. The camera body 2 is mounted on the robot body 1 via the multi-degree-of-freedom rotating camera rotation platform 3 to expand the inspection range of the inspection robot.

[0033] The camera rotation platform 3 includes a first rotation platform 31 and a rotation bracket 32 ​​arranged sequentially from bottom to top. The upper surface of the robot body 1 is provided with a first rotation groove 11, and the first rotation platform 31 is horizontally rotatably connected to the first rotation groove 11.

[0034] In order to reduce the frictional resistance between the first rotating platform 31 and the robot body 1 when the first rotating groove 11 rotates, an annular groove (not shown in the figure) is provided at the bottom of the first rotating groove 11. Multiple balls (not shown in the figure) are evenly distributed in the annular groove along its circumferential direction, and all the balls abut against the bottom of the first rotating platform 31.

[0035] The rotation of the first rotating platform 31 along the robot body 1 is driven by the first driving mechanism 4, which includes a first driven gear 41, a first driving gear 42, and a pulley assembly 43. The first driven gear 41 is horizontally disposed inside the robot body 1 and is fixedly connected to the first rotating platform 31 via a connecting shaft, and the connecting shaft is rotatably connected to the robot body 1; the first driving gear 42 is horizontally rotatably connected inside the robot body 1 and meshes with the first driven gear 41 for transmission.

[0036] The pulley assembly 43 includes a driven pulley, a driving pulley, and a first motor. The driven pulley is horizontally positioned below and fixedly connected to the first driving gear 42. The driving pulley is mounted on the first motor and is connected to the driven pulley via a belt. Power transmission is achieved through the pulley assembly 43 and the first drive mechanism 4, indirectly enabling the first motor to drive the rotation of the first rotating platform 31.

[0037] The diameter of the first driven gear 41 is larger than the diameter of the first driving gear 42 to achieve speed reduction transmission, ensure the stability of power transmission, and thus ensure the rotational stability of the first driven gear 41. At the same time, in order to further ensure the stability of the rotational state of the first driven gear 41, and thus ensure the rotational stability of the first rotating platform 31, multiple auxiliary gears 12 are evenly arranged at the top position inside the robot body 1 along the circumferential direction of the first driven gear 41 and are rotatably connected to the robot body 1 through connecting shafts. All the auxiliary gears 12 mesh with the first driven gear 41 for transmission.

[0038] The rotating bracket 32 ​​is vertically mounted on the upper surface of the first rotating platform 31, and includes a pair of opposing vertical frames 321. The camera body 2 is positioned between the pair of vertical frames 321, and both sides of the camera body 2 are rotatably connected to the pair of vertical frames 321 in the vertical direction, meaning that the camera body 2 can rotate in the vertical direction.

[0039] The rotation of the camera body 2 along the vertical direction of the rotating bracket 32 ​​is achieved by the second drive mechanism 5, which includes a second motor 51, a pair of second driven gears 52 and a pair of second driving gears 53. The pair of second driven gears 52 are respectively vertically arranged in a pair of vertical frames 321 and are fixedly connected to the camera body 2 through a connecting shaft, and the connecting shaft and the vertical frame 321 are rotatably connected.

[0040] A pair of second driving gears 53 are vertically rotatably connected to a pair of vertical frames 321 and are correspondingly distributed below a pair of second driven gears 52, and mesh with the second driven gears 52 for transmission. The second motor 51 is connected to one of the second driving gears 53 to realize the vertical rotation drive of the camera body 2 through gear transmission. With the rotation of the first rotating platform 31 in the horizontal direction, the camera body 2 can be adjusted in multiple degrees of freedom (vertical + horizontal), thereby expanding the camera's shooting range and thus expanding the inspection range of the inspection robot.

[0041] Similar to the first driven gear 41 and the first driving gear 42, the diameter of the second driven gear 52 is also larger than that of the second driving gear 53 to achieve speed reduction transmission, ensure the stability of power transmission, ensure the rotational stability of the second driven gear 52, and thus ensure the stability of the camera body 2 rotating along the rotating bracket 32.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
