Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicle equipment, and in particular relates to an unmanned aerial vehicle inspection device for identifying surface ecological changes in mining areas. Background Art

[0002] Drone inspections to identify surface ecological changes in mining areas are a highly efficient and accurate monitoring method. Equipped with high-definition cameras and multispectral or thermal infrared sensors, drones can regularly capture high-resolution images of mining areas, capturing real-time changes in vegetation cover, soil erosion, and subsidence expansion. Their advantages lie in their flexibility, low cost, and high data accuracy. They can quickly identify subtle changes in areas difficult to reach manually, and generate dynamic maps of these changes through AI image analysis. This provides a scientific basis for ecological restoration, pollution prevention and control, and resource management, significantly improving the sustainable development and environmental protection of mining areas.

[0003] Although drone inspections for identifying surface ecological changes in mining areas have achieved efficient photography and detection, there are still obvious limitations. Drones can only complete real-time collection of surface images. For suspected abnormal areas (such as patches of vegetation degradation, areas with abnormal soil color, collapse edges, etc.), the system can only mark the location and generate data reports. Subsequently, it is still necessary to rely on manual labor to carry sampling equipment back to the site for soil sampling, laboratory testing and other operations. This process results in a time difference from abnormality discovery to data verification, and it is impossible to immediately confirm the type, degree and spread of pollution. This not only prolongs the response cycle to ecological problems, but also increases labor costs and safety risks, restricting the real-time and accuracy of ecological monitoring in mining areas.

[0004] To this end, we provide drone inspection devices for identifying surface ecological changes in mining areas to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] See also Figures 1-8 The present invention is a drone inspection device for identifying surface ecological changes in mining areas, comprising a drone body 1, a drive shell 2 mounted on the bottom of the drone body 1, and an inspection probe 3 mounted on the front side of the drive shell 2; a sampling assembly 4 is provided at the bottom of the drone body 1, and the sampling assembly 4 comprises a through slot 401 opened inside the drive shell 2, a rotating shaft 402 movably connected to the through slot 401, an adjusting shell 403 mounted on the surface of the rotating shaft 402, and a sampling shell 404 disposed inside the adjusting shell 403. The sampling assembly 4 is used to detect abnormalities detected during inspection. Real-time sampling is performed in normal areas; a driving assembly 5 is provided inside the driving shell 2, and the driving assembly 5 includes a gear 501 provided inside the adjusting shell 403, and a toothed plate 502 engaged with one side of the gear 501. The positions of the two groups of sampling shells 404 are adjusted by the driving assembly 5; a sealing assembly 6 is provided inside the sampling shell 404, and the sealing assembly 6 includes a support shaft 601 movably connected to the inside of the sampling shell 404, and a baffle 602 installed on the surface of the support shaft 601. The soil after sampling is sealed by the sealing assembly 6.

[0034] Specifically: the inspection probe 3 is located on the front side of the drone body 1 and is used to shoot the mining environment. The video probe 12 is located at the bottom of the drone body 1 and is used to shoot the environment below. It can also shoot the sampling process of the sampling shell 404, which is convenient for remote monitoring by the staff. There are two groups of sampling shells 404. The two groups of sampling shells 404 are fixed with two groups of gear plates 502. The gear 501 is engaged between the two groups of gear plates 502. When the gear 501 rotates, it can push the two groups of sampling shells 404 to move alternately.

[0035] Example 2

[0036] See also Figures 1-8 On the basis of Example 1, a first clockwork spring 7 is fixedly connected to the surface of the rotating shaft 402, and the other end of the first clockwork spring 7 is fixedly connected to the inner wall of the drive shell 2. The driving assembly 5 also includes a first motor 503 arranged inside the adjusting shell 403, a driving shaft 504 installed at the output end of the first motor 503, and the other end of the driving shaft 504 is fixedly connected to the gear 501. A bracket 8 is fixedly connected to the surface of the first motor 503, and one side of the bracket 8 is fixedly connected to the inner wall of the adjusting shell 403. The sealing assembly 6 also includes a second clockwork spring 603 installed on the surface of the support shaft 601, a cross bar 604 is provided on one side of the baffle 602, one side of the cross bar 604 is fixedly connected to the inner wall of the sampling shell 404, and the other end of the second clockwork spring 603 is fixedly connected to the inner wall of the sampling shell 404.

[0037] Specifically: the surface of the support shaft 601 is movably connected to the inner wall of the sampling shell 404 through a bearing. After the sampling shell 404 is inserted into the soil layer, the soil can push the baffle 602 to rotate and enter the sampling shell 404, and seal the sampled soil. The first clockwork spring 7 has the function of twisting energy storage, and can drive the adjustment shell 403 to rotate downward and contact the soil layer when the second motor 901 releases the winding roller 902 and the traction rope 903. The first motor 503 and the second motor 901 are both micro motors. The first motor 503 is used to provide power to the gear 501, and the second motor 901 is used to provide power to the winding roller 902.

[0038] Example 3

[0039] See also Figures 1-8On the basis of Examples 1 and 2, a reset assembly 9 is provided inside the drive housing 2, and the reset assembly 9 includes a second motor 901 installed inside the drive housing 2, a winding roller 902 installed at the output end of the second motor 901, a traction rope 903 sleeved on the surface of the winding roller 902, and the other end of the traction rope 903 is fixedly connected to the adjustment housing 403. The surface of the winding roller 902 is movably connected to the inner wall of the drive housing 2 through a bearing, and an auxiliary wheel 10 is sleeved on the surface of the traction rope 903. One side of the auxiliary wheel 10 is movably connected to the inner wall of the drive housing 2 through a second bearing. A support rod 11 is slidably connected to the inside of the gear plate 502, and one side of the support rod 11 is fixedly connected to the inner wall of the adjustment housing 403. A video probe 12 is installed at the bottom of the drive housing 2, a support leg 13 is fixedly connected to the bottom of the drone body 1, and a buffer pad 14 is fixedly connected to the surface of the support leg 13.

[0040] Specifically: the bracket 8 is used to fix the first motor 503 to improve the stability of the first motor 503 when it is working. The second spring 603 has the function of twisting energy storage. When the sampling shell 404 moves out of the soil layer, the baffle 602 can be reset to prevent the soil from falling off after sampling. The traction rope 903 is connected between the winding roller 902 and the adjusting shell 403 to fix the position of the adjusting shell 403. The auxiliary wheel 10 can support the sliding of the traction rope 903, and the buffer pad 14 can buffer the impact force of the support leg 13 contacting the soil layer.

[0041] The working principle of the present invention is as follows: the staff drives the unmanned aerial vehicle 1 to inspect the mining environment and uses the inspection probe 3 to transmit images. When the staff finds an abnormal area, the unmanned aerial vehicle 1 can be driven to land. After the unmanned aerial vehicle 1 lands in the sampling area, the second motor 901 can be started, and the second motor 901 drives the winding roller 902 to rotate. The winding roller 902 rotates to release the traction rope 903. At this time, the first clockwork spring 7 resets the rotating shaft 402, and the rotating shaft 402 drives the adjusting shell 403 to contact the ground.

[0042] Then, the first motor 503 is started. The first motor 503 cooperates with the drive shaft 504 to drive the gear 501 to rotate. The gear 501 drives the two sets of tooth plates 502 to move in opposite directions. When the tooth plates 502 move, they drive a set of sampling shells 404 to extend out of the adjustment shell 403 and insert into the soil layer. The soil enters the sampling shell 404 and pushes the baffle 602 to rotate and enter the sampling shell 404.

[0043] Then, the first motor 503 is controlled to drive the gear 501 to rotate in the opposite direction, driving the sampling shell 404 to reset. The second spring 603 has the function of twisting energy storage. When the sampling shell 404 takes out the soil layer, the baffle 602 can be reset to prevent the soil from falling off after sampling, thereby completing the sampling. There are two groups of sampling shells 404, and re-sampling can be performed when the unmanned aerial vehicle body 1 inspects different positions, thereby improving the sampling efficiency.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
