[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As shown in Figure 1-3:

[0025] A drone inspection auxiliary device includes a drone body 101, and a base plate 103 is fixedly installed on the bottom of the drone body 101.

[0026] Camera 102 is located below the base plate 103;

[0027] U-shaped seat 104 is fixedly installed on the lower surface of base plate 103;

[0028] The buffer mechanism 2 is installed on the U-shaped base 104 and is used to buffer the impact of the camera 102.

[0029] The buffer mechanism 2 includes a connecting plate 202 disposed below the base plate 103, and the connecting plate 202 is located between the U-shaped seat 104 and the base plate 103. A U-shaped plate 201 is fixed on the lower surface of the connecting plate 202. A buffer airbag 203 is disposed between the U-shaped seat 104 and the connecting plate 202. The buffer airbag 203 is fixed on the inner side wall of the U-shaped seat 104. A symmetrically arranged limiting rod 207 is fixed on the lower surface of the base plate 103. A moving hole adapted to the limiting rod 207 is opened on the connecting plate 202, and the connecting plate 202 can slide on the limiting rod 207.

[0030] The buffer mechanism 2 also includes connecting blocks 205 fixed on both sides of the U-shaped plate 201. An electric telescopic rod 206 is fixed on the lower surface of the base plate 103 near the connecting block 205. A buckle plate 204 is fixedly installed at the output end of the electric telescopic rod 206. The buckle plate 204 is located directly below the connecting block 205.

[0031] The adjustment mechanism 3 is installed on the buffer mechanism 2 and is used to adjust the camera 102 in multiple directions.

[0032] The adjustment mechanism 3 includes a movable shaft 302 rotatably mounted on the bottom of the U-shaped plate 201 via a bearing. A U-shaped frame 301 is fixedly mounted on the bottom of the movable shaft 302. The camera 102 is mounted on the U-shaped frame 301. A first motor 303 is fixedly mounted on the bottom of the U-shaped plate 201. A first gear 304 is fixedly mounted on the output end of the first motor 303. A second gear 305 that meshes with the first gear 304 is fixedly mounted on the surface of the movable shaft 302.

[0033] The adjustment mechanism 3 also includes a hinge shaft 309 rotatably mounted on the U-shaped frame 301 via a bearing. The camera 102 is fixedly mounted on the surface of the hinge shaft 309. A second motor 306 is fixedly mounted on the inner side wall of the U-shaped frame 301. A third gear 307 is fixedly mounted on the output end of the second motor 306. One end of the hinge shaft 309 extends to the outside of the U-shaped frame 301 and is fixedly connected to a fourth gear 308 on the outside of the U-shaped frame 301. The fourth gear 308 and the third gear 307 are meshed together.

[0034] A gas detector is also installed on the camera 102, and a rubber pad is fixed to the lower surface of the base plate 103.

[0035] In this implementation plan: During use, the drone inspection auxiliary device allows the drone body 101 to fly the camera 102 and gas detector (not shown in the figure) to the designated inspection area for inspection operations;

[0036] During this process, the second motor 306 is started, thereby driving the third gear 307 to rotate. Since the third gear 307 is meshed with the fourth gear 308, the rotation of the third gear 307 will drive the fourth gear 308 to rotate. The rotation of the fourth gear 308 will then drive the hinge shaft 309 to rotate, so that the camera 102 can adjust its vertical angle.

[0037] At the same time, the first motor 303 is started, driving the first gear 304 to rotate. The first gear 304 meshes with the second gear 305. The rotation of the first gear 304 drives the second gear 305 to rotate. The rotation of the second gear 305 drives the U-shaped frame 301 and the camera 102 to rotate synchronously through the rotation of the movable shaft 302, thereby realizing the left and right angle adjustment of the camera 102.

[0038] The camera 102 rotates synchronously to achieve left and right angle adjustment. Through the adjustment mechanism 3, the direction and posture of the camera 102 can be driven independently to make precise angle adjustment so as to capture images or videos in a specific direction, making the adjustment process more flexible and practical and meeting actual use needs.

[0039] When the drone body 101 carrying the camera 102 lands, the electric telescopic rod 206 extends, thereby causing the buckle plate 204 to release the pressure on the connecting block 205, maintaining a certain buffer distance between the buckle plate 204 and the connecting block 205. When the drone body 101 lands, the impact force causes the U-shaped plate 201 to slide the connecting plate 202 on the limiting rod 207. The limiting rod 207 acts as a guide and limiter for the connecting plate 202, ensuring that it can only move up and down. When subjected to impact, the connecting plate 202 slides downwards on the surface of the limiting rod 207, and then presses down towards the buffer airbag 203. The buffer airbag 203 cushions the impact on the connecting plate 202, effectively reducing the downward impact on components such as the camera 102.

[0040] When the main body of the drone 101 is conducting flight inspections, the electric telescopic rod 206 retracts, causing the buckle plate 204 to move upward, which in turn presses the connecting block 205 upward. At the same time, the connecting block 205 causes the U-shaped plate 201 and the connecting plate 202 to move upward synchronously, so that the connecting plate 202 is tightly attached to the bottom of the base plate 103, ensuring the stability of components such as the U-shaped plate 201 and the camera 102 and reducing shaking.

[0041] A rubber pad is fixed on the lower surface of the base plate 103. When the connecting plate 202 collides with the base plate 103, the rubber pad further improves the cushioning effect.

[0042] This solution can effectively absorb and disperse the impact energy generated by the UAV body 101 during high-speed landing, reduce the impact on precision equipment such as the fuselage and camera 102, thereby reducing the risk of equipment damage and ensuring the integrity and long-term stable operation of the UAV body 101 and its onboard equipment.

[0043] It should be noted that all electrical equipment involved in this product is powered by the power distribution system of the UAV body 101 itself. The solution also includes a controller, which is installed on the UAV body 101. During use, each electrical device can be started and operated through the controller. The power connection method of each electrical device is a mature existing technology and is well known to those in the art. It will not be described in detail here.

[0044] Meanwhile, the contents of the UAV body 101 and the gas detector not described in detail in this specification are all existing technologies known to those skilled in the art. The gas detector is the DP-4S built-in pump suction type four-in-one gas detector, which is a four-in-one gas detection instrument equipped with a combustible gas sensor, an oxygen sensor, a carbon monoxide sensor and a hydrogen sulfide sensor.

[0045] Second embodiment:

[0046] In an optional embodiment, the buffer mechanism 2 includes a connecting plate 202 disposed below the base plate 103, and the connecting plate 202 is located between the U-shaped seat 104 and the base plate 103. A U-shaped plate 201 is fixed to the lower surface of the connecting plate 202. Two sets of buffer airbags 203 are provided, one set is disposed between the U-shaped seat 104 and the connecting plate 202 and fixed to the inner side wall of the U-shaped seat 104, and the other set is fixed to the lower surface of the base plate 103. A symmetrically arranged limiting rod 207 is fixed to the lower surface of the base plate 103. The connecting plate 202 is provided with a moving hole adapted to the limiting rod 207, and the connecting plate 202 can slide on the limiting rod 207.

[0047] The lower surface of the base plate 103 is fixedly installed with symmetrically arranged electric telescopic rods 206 via a support plate, and the output ends of the two sets of electric telescopic rods 206 are located on both sides of the U-shaped plate 201.

[0048] In this embodiment: when the drone body 101 carrying the camera 102 lands, the electric telescopic rod 206 is activated to retract, relieving the pressure on both sides of the U-shaped plate 201. When the drone body 101 lands, the impact force will cause the U-shaped plate 201 to drive the connecting plate 202 to slide on the limiting rod 207. The setting of the limiting rod 207 plays a limiting and guiding role for the connecting plate 202, ensuring that the connecting plate 202 can only move up and down. When subjected to impact force, the connecting plate 202 slides downward on the surface of the limiting rod 207. The two sets of buffer airbags 203 can buffer the connecting plate 202 up and down, thereby effectively reducing the downward impact on components such as the camera 102.

[0049] When the main body of the drone 101 is conducting flight inspections, the electric telescopic rod 206 extends to press and fix the two sides of the U-shaped plate 201, ensuring the stability of components such as the U-shaped plate 201 and camera 102, and reducing shaking.

[0050] The working principle and usage process of this utility model are as follows: During use, the drone body 101 can fly the camera 102 and gas detector (not shown in the figure) to the designated inspection area for inspection. During this process, the second motor 306 is activated, driving the third gear 307 to rotate. Since the third gear 307 is meshed with the fourth gear 308, the rotation of the third gear 307 will drive the fourth gear 308 to rotate. The rotation of the fourth gear 308, in turn, drives the hinge shaft 309 to rotate, allowing the camera 102 to adjust its vertical angle. Simultaneously, the first motor 303 is activated, driving the first gear 304 to rotate. The first gear 304 is meshed with the second gear 305, and the rotation of the first gear 304 thus drives the second gear 305 to rotate. The rotation of the second gear 305 drives the rotation of the movable shaft 302, which in turn drives the U-shaped frame 301 and the camera 102 to rotate synchronously, thereby achieving the left and right angle adjustment of the camera 102. Through the adjustment mechanism 3, the direction and attitude of the camera 102 can be driven independently to make precise angle adjustments so as to capture images or videos in a specific direction, making the adjustment process more flexible and practical and meeting actual use needs. When the drone body 101 carrying the camera 102 lands, the electric telescopic rod 206 is activated to extend, thereby causing the buckle plate 204 to release the pressure on the connecting block 205, so that a certain buffer distance is maintained between the buckle plate 204 and the connecting block 205. When the main body of the drone 101 lands, the impact force will cause the U-shaped plate 201 to slide the connecting plate 202 on the limiting rod 207. The setting of the limiting rod 207 plays a limiting and guiding role for the connecting plate 202, ensuring that the connecting plate 202 can only move up and down. When subjected to impact force, the connecting plate 202 slides downward on the surface of the limiting rod 207, and then presses down in the direction of the buffer airbag 203, so that the buffer airbag 203 can buffer the impact on the connecting plate 202.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
