[0037] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0038] like Figure 1-Figure 7 As shown, an intelligent inspection drone with adjustable arms includes a body 10, and an inspection device 20 is fixedly arranged at the bottom of the body 10.

[0039] The inspection device 20 includes an inspection camera 21 and a searchlight device 22, which are used to searchlight, inspect and measure the inspection area to ensure that the operation status of the line can be mastered and equipment defects and problems threatening line safety can be discovered in time;

[0040] The adjustment mechanism 30 includes connection blocks 31 fixedly arranged on both sides of the body 10, and the connection blocks 31 are provided with adjustment components 32, which are used to drive the machine arm to adjust, so as to ensure that the machine arm can be adjusted to pass through different flight spaces when performing inspection work;

[0041] The arm assembly 40 includes an adjustment arm 41 and a folding arm 42. The adjustment arm 41 is slidably disposed at the output end of the adjustment assembly 32. The adjustment arm 41 is rotatably connected to the folding arm 42 and the body 10 through a transmission mechanism 50;

[0042] The transmission mechanism 50 includes a transmission assembly 51 fixedly arranged at the output end of the adjustment assembly 32, and a driving gear 52 rotatably arranged in the body 10, the transmission assembly 51 is transmission-connected with the driving gear 52, and the transmission assembly 51 is also transmission-connected with a driven gear 53, and the driven gear 53 is arranged in the folding arm 42;

[0043] Among them, the output end of the adjustment component 32 is slidably arranged in the adjustment arm 41, thereby driving the transmission component 51 to perform transmission work in the adjustment arm 41. Since the adjustment arm 41 is rotatably arranged in the body 10 through the driving gear 52, and the driving gear 52 is connected to the transmission component 51 for transmission, the adjustment arm 41 is driven to rotate and adjust along the driving gear 52. Since the driven gear 53 is rotatably connected to the transmission component 51, and the driven gear 53 is arranged in the folding arm 42, the folding arm 42 is driven to fold, completing the adjustment work of the arm assembly 40, so that the drone can pass through a relatively narrow space when performing inspection work.

[0044] It should be noted that a remote control device is used in conjunction with the drone body, and the remote control device is electrically connected to the inspection device 20 and the adjustment component 32, so that they can be controlled and adjusted through the remote control device.

[0045] In this embodiment, the body 10 serves as the core structure of the UAV, providing a stable foundation and sufficient carrying capacity. By fixing the inspection device 20 at the bottom of the body 10, the inspection area can be inspected and measured to ensure the equipment operation status in the inspection area, and equipment defects can be discovered and notified in time to ensure timely repair. Among them, the inspection device 20 includes an inspection camera 21 and a searchlight 22. The inspection camera 21 is used to capture high-definition images in the inspection area, and can also magnify some details. The searchlight 22 provides necessary lighting to ensure effective inspection and measurement under various lighting conditions. The searchlight 22 can provide sufficient lighting at night or in low-light environments, so that the inspection camera 21 can clearly capture images of the inspection area. Specifically, the inspection camera 21 can not only capture images, but also may have measurement functions, such as evaluating the status of the line through comparative analysis, and discovering equipment defects or potential safety threats in time. The adjustment mechanism 30 is used to drive the arm assembly 40 located on the body 10 to rotate and adjust, and can adjust the position of the arm according to different flight space requirements, so that the UAV can flexibly shuttle in a complex environment. At the same time, through the use of the adjustment mechanism 30, the stability of the UAV during flight can be greatly improved, and the arm can be adjusted according to different flight conditions, so that the arm can adapt to different environments and provide stability in use. Among them, the adjustment mechanism 30 includes a connection block 31 fixedly arranged on both sides of the body 10, and the connection block 31 can serve as an installation base for the adjustment assembly 32, providing stable support for the use and installation of the adjustment assembly 32. By fixing the adjustment assembly 32 on the connection block 31, the opening and closing of the adjustment assembly 32 can drive the arm assembly 40 to perform precise adjustment. The arm assembly 40 is used to provide stable power for the UAV to perform flight operations, and at the same time can ensure the stability of the UAV during operation. The arm assembly 40 includes an adjustment arm 41 slidably arranged at the output end of the adjustment assembly 32. The adjustment arm 41 is the main structure for adjusting and folding the arm assembly 40. It can connect the body 10 and the folding arm 42 through the transmission mechanism 50 to ensure the stability of the body 10 during flight. At the same time, it provides support for the folding adjustment of the folding arm 42. The folding arm 42 can be folded by cooperating with the adjustment arm 41 to adapt to different flight environments and mission requirements, ensuring that it can be folded, contracted and extended simultaneously with the adjustment arm 41 under the drive of the adjustment assembly 32. The transmission mechanism 50 is used to transmit the power generated by the adjustment mechanism 30, so that the arm assembly 40 completes the adjustment work. The transmission mechanism 50 includes a transmission assembly 51, which is fixedly arranged at the output end of the adjustment assembly 32 and can transmit the power of the adjustment assembly 32 to various parts of the arm assembly 40.Since the driving gear 52 is rotatably disposed in the machine body 10 and is in transmission connection with the transmission assembly 51, the power of the adjustment assembly 32 can be transmitted to the driving gear 52, and the adjustment arm 41 is driven to rotate and adjust along the driving gear 52. By rotating the driven gear 53 and connecting it to the transmission assembly 51 and being disposed in the folding arm 42, the folding arm 42 is driven to fold, and the adjustment work of the machine arm assembly 40 is completed.

[0046] Preferably, by providing a rotation groove 311 on the connection block 31, a space can be provided for the rotation ring 312 so that it can rotate freely. The rotation ring 312 is arranged in the rotation groove 311 to form a rotation connection with the connection block 31. The adjustment component 32 is fixedly connected to the rotation ring 312 so that the adjustment component 32 can rotate with the rotation ring 312. The rotation connection between the rotation ring 312 and the connection block 31 provides a smooth rotation process, ensures the stability of the adjustment component 32 when working, and reduces the vibration and instability caused by the adjustment of the motor arm bar.

[0047] like Figure 3 , Figure 5 , Figure 6 As shown, by fixing the adjusting push rod 321 in the adjusting assembly 32 on the rotating ring 312, it is the adjusting power source of the adjusting assembly 32, and can transmit power to subsequent components. By rotating the connecting rod 322 at the output end of the adjusting push rod 321 and forming a rotation connection with the adjusting push rod 321, it can be ensured that the adjusting push rod 321 effectively drives the connecting rod 322 to move after being started, and at the same time, through its rotation connection with the adjusting block 323, it can make the power act on the adjusting block 323, and drive the adjusting block 323 to move in the adjusting arm 41. By sliding the adjusting block 323 in the adjusting arm 41, and rotating it with the connecting rod 322, and the adjusting block 323 is fixedly connected to the transmission assembly 51. Specifically, when the adjusting push rod 321 can accurately push the connecting rod 322, thereby driving the adjusting block 323 to slide in the adjusting arm 41, since the adjusting arm 41 is rotationally connected to the body 10 through the driving gear 52, it can drive the adjusting arm 41 to rotate along the driving gear 52, thereby realizing the precise adjustment of the machine arm. The fixed connection between the adjustment block 323 and the transmission assembly 51 ensures high efficiency of power transmission, so that the adjustment action of the machine arm is fast and accurate.

[0048] like Figure 3 , Figure 6As shown, the transmission assembly 51 includes a transmission chain 511 meshed with the driving gear 52 and the driven gear 53, and the transmission chain 511 is also fixedly connected to the adjustment block 323 to ensure that power can be transmitted to each part of the arm. The transmission chain 511 can transmit the power generated by the adjustment assembly 32 to the driving gear 52 and the driven gear 53, ensuring that when the adjustment push rod 321 drives the adjustment block 323 to move, it can effectively drive the driving gear 52 and the driven gear 53 to rotate. Among them, the transmission assembly 51 also includes a transmission guide rod 512, which is rotatably connected to the adjustment arm 41 and fixedly connected to the driven gear 53, so as to provide the transmission assembly 51 with stability in the transmission structure. The combined use of the transmission chain 511 and the transmission guide rod 512 in the transmission assembly 51 makes the power transmission more efficient, thereby improving the response speed and accuracy of the arm adjustment. The design of the transmission assembly 51 enables the arm of the drone to be flexibly operated in a narrow space, thereby improving its inspection capability in a complex environment.

[0049] like Figure 1 , Figure 2 , Figure 4 As shown, one end of the adjusting arm 41 is rotatably connected to the machine body 10, so that the machine arm can be flexibly adjusted in position as needed. By fixing the driving gear 52 at one end of the adjusting arm 41 rotatably connected to the machine body 10, it is possible to receive power from the transmission assembly 51 and drive the machine arm for adjustment. Among them, the other end of the adjusting arm 41 is rotatably connected to the folding arm 42 through the transmission guide rod 512, ensuring that the folding arm 42 can be unfolded or folded accordingly with the movement of the adjusting arm 41. Specifically, by providing a sliding groove 411 in the adjusting arm 41, a sliding path can be provided for the adjusting block 323, so that the adjusting block 323 can slide freely therein. The adjusting block 323 can move accurately in the sliding groove 411 according to the movement of the adjusting assembly 32, thereby driving the transmission assembly 51 to work.

[0050] In this embodiment, the adjusting component 32 can drive the transmission component 51 fixedly connected to its output end, and then drive the driving gear 52 and the driven gear 53 connected to it through the transmission component 51. The driving gear 52 is fixedly arranged in the adjusting arm 41, and the driven gear 53 is fixedly arranged in the folding arm 42, so as to drive the arm component 40 to complete the adjustment work.

[0051] Preferably, the inspection device 20 also includes a lifting assembly 23 fixedly arranged at the bottom of the body 10, and the lifting assembly 23 can effectively drive the inspection structure at its output end to be adjusted. By fixing the inspection camera 21 at the output end of the lifting assembly 23, the inspection camera 21 can be adjusted following the lifting assembly 23, so as to realize inspections at different angles and directions, and ensure accuracy during the inspection process.

[0052] like Figure 1 , Figure 3 , Figure 7 As shown, by fixing the lifting push rod 231 in the lifting assembly 23 at the bottom of the body 10, the lifting plate 232 can be driven to move up and down, thereby realizing the vertical position adjustment of the inspection camera 21 and the searchlight device 22, ensuring that they will not be blocked by obstacles during the inspection process. By fixing the lifting plate 232 at the output end of the lifting push rod 231, it can be used as the main platform for supporting the inspection camera 21 and the searchlight device 22, ensuring the stability of the inspection device 20 when in use. A support plate 233 is also fixedly arranged on the lifting plate 232, which is used to provide a fixed platform for the support adjustment rod 234, ensuring the stability of the support adjustment rod 234 when in use, and at the same time increasing the stability of the lifting assembly 23 when in use. By arranging the support adjustment rod 234 at the bottom of the support plate 233, and rotating the adjustment slider 235 at its output end, it can effectively cooperate with the adjustment slide rail 236 arranged at the bottom of the lifting plate 232, and can adjust the angle of the inspection camera 21, so that the inspection camera 21 can obtain a larger inspection range. By rotating the adjustment rail 236 at the bottom of the lifting plate 232 and sliding the adjustment slider 235 inside the adjustment rail 236, the inspection camera 21 and the searchlight 22 at the bottom can be driven through the fixed plate 237 for precise adjustment.

[0053] In the embodiment of the present invention, the lifting plate 232 at the output end thereof, as well as the inspection camera 21 and the searchlight device 22 arranged at the bottom of the lifting plate 232 can be driven to be raised and lowered by starting the lifting push rod 231. Then, the support adjustment rod 234 arranged at the bottom of the support plate 233 is controlled to work, so that it drives the adjustment slider 235 at the output end thereof to move. Since the adjustment slider 235 is slidably arranged in the adjustment slide rail 236, and the adjustment slide rail 236 is rotatably connected to the bottom of the lifting plate 232, the adjustment slide rail 236 can be driven to adjust the angle, so that the inspection camera 21 at the bottom thereof can be driven to adjust the angle by fixing the fixing plate 237 fixed at the bottom of the adjustment slide rail 236, so that the inspection device 20 can obtain a wider inspection angle.

[0054] Preferably, the inspection camera 21 has a night vision module, which can take clear pictures at night or in an environment with insufficient light. And it has a recording module, which can record the key parts of the inspection area, so as to capture high-definition images and conduct focused observation. It also has an amplification module, which can amplify the image details by setting the device in the inspection camera 21, which helps the inspection device 20 to conduct a more careful inspection of a specific area. Among them, the searchlight in the searchlight device 22 is used to provide lighting for the inspection drone when the light is dim or at night, so as to ensure the normal progress of the inspection work. Among them, the searchlight is adjustable on the body 10 through the adjustment frame 221, and the adjustment frame 221 is detachably connected to the searchlight, so that the searchlight can be quickly replaced, and the searchlight can be driven by the adjustment frame 221 to adjust. By cooperating with the searchlight in the searchlight device 22 and the inspection camera 21, the efficiency of the inspection task can be improved, and it can cooperate with the inspection camera 21 to identify potential hidden dangers such as damage on the surface of the equipment and abnormal temperature during the inspection of facilities such as power lines and photovoltaic panels.

[0055] The working principle of the present invention is as follows: when the adjusting push rod 321 performs the recovery work, it can drive the connecting rod 322 at its output end to move, and since the connecting rod 322 is respectively connected to the adjusting push rod 321 and the adjusting block 323 for rotation, the adjusting block 323 can be driven. The adjusting block 323 is moved in the sliding groove 411 provided in the adjusting arm 41, and since the adjusting block 323 is fixedly connected to the transmission chain 511 in the transmission assembly 51, the transmission chain 511 is driven to move, and since the transmission chain 511 is respectively meshed and connected with the driving gear 52 and the driven gear 53, the driving gear 52 is driven to rotate. The adjusting arm 41 is fixedly connected to the driving gear 52, and the driving gear 52 is connected to the machine body 10 for rotation through the pin, and the adjusting arm 41 is driven to rotate along the pin on the machine body 10. When the adjusting arm 41 rotates, the driven gear 53 can be driven to rotate through the transmission chain 511, and because the driven gear 53 is fixedly connected to the folding arm 42, the folding arm 42 is rotatably connected to the adjusting arm 41 through the transmission guide rod 512, thereby driving the folding arm 42 to fold and adjust. The adjusting assembly 32 can drive the transmission assembly 51 to act on the machine arm assembly 40, so that the machine arm assembly 40 is adjusted and folded at the same time. When the machine arm assembly 40 needs to be extended, the adjustment push rod 321 is started to extend it, thereby driving the adjustment block 323 to move in the opposite direction in the sliding groove 411, and then driving the folding arm 42 and the adjusting arm 41 to extend through the transmission assembly 51.

[0056] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
