Description

Technical Field

[0001] The present invention relates to the technical field of inspection drones, and in particular to an intelligent inspection drone device. Background Art

[0002] Traditional railway inspections are mostly conducted during the day. However, with the continuous growth of railway transportation business, railway operations are extremely busy during the day, and routine inspections can easily interfere with normal transportation. In addition, in some complex sections, such as mountain railways, the terrain is rugged and the surrounding vegetation is dense, which brings great difficulties to the inspection work. Currently, inspection drones have been widely used in railway inspections. The high-definition cameras and thermal imagers they carry can obtain key data and assist inspectors in judging the status of railway facilities. However, in the dark environment at night, the performance of these devices will be significantly limited, making it difficult to conduct comprehensive and accurate inspections of railway facilities. For example, the inspection drone with Chinese patent publication number CN115123565A; During the stable flight of the drone along the rails, the strong light emitted by the lighting equipment effectively penetrates the dark environment and clearly illuminates the rails, sleepers and surrounding related facilities. Through this lighting effect, the drone can accurately identify whether there are foreign objects on the rails, whether the fasteners are loose, etc. When the drone flies over the bridge area, the lighting equipment can fully illuminate the bridge body, so that the inspection personnel can use the image data sent back by the drone to carefully check whether there are cracks in the bridge structure and whether the welds are firm and reliable. When passing through the tunnel, the lighting equipment can effectively dispel the darkness in the tunnel and help the drone accurately identify whether there are any damages to the cables on the tunnel wall and whether the suspension devices are in normal working condition. With the lighting equipment of the inspection drone of the present invention, the inspection drone can efficiently and accurately complete the railway inspection task in the complex environment at night, effectively ensuring the safe and smooth operation of the railway the next day, significantly improving the safety and reliability of the railway transportation system, and effectively solving the many problems caused by insufficient light in the existing technology during railway inspection at night; Considering that the light from lighting equipment is relatively scattered when illuminating in the dark, it is easy to miss some foreign objects on the rails that are difficult to see during the inspection process. If the missed foreign objects are large or have sharp edges, the wheels may run over the foreign objects when the train is running at high speed, causing wheel wear and deformation, and even causing derailment accidents, which seriously threatens the safety of train operation and endangers the lives of passengers and cargo.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example

[0018] See also Figures 1-8 As shown, this embodiment provides an intelligent inspection drone device, including a fuselage body 100, four propellers 110 fixedly connected to the top of the fuselage body 100, a support platform 120 fixedly connected to the inner cavity of the fuselage body 100, a motor 1201 fixedly connected to the inner cavity of the support platform 120, and a lighting device 130 rotatably connected to the output end of the motor 1201; The output end surface of the motor 1201 is provided with a rotation support assembly 200, which is located at the lower end of the lighting device 130 and is used to support the lighting device 130 to rotate; A condenser lens assembly 300 is provided above the body 100 and is located on the light emission path of the lighting device 130; An adjustment assembly 400 is provided on the surface of the rotating support assembly 200. The adjustment assembly 400 is connected to the condenser lens assembly 300 and synchronously supports the condenser lens assembly 300 and the adjustment assembly 400 through the rotating support assembly 200, so that the condenser lens assembly 300 and the adjustment assembly 400 rotate synchronously with the lighting device 130. The adjustment component 400 is used to adjust the distance between the condenser lens component 300 and the lighting device 130, and to focus or expand the illumination range of the lighting device 130 by changing the position of the condenser lens component 300; When it is necessary to inspect the railway, the inspection drone is first started, and the four propellers 110 fixedly connected to the top of the fuselage body 100 start to operate, generating strong lift, which steadily lifts the drone and maintains the flight state, so that it can move along the railway. Then, the motor 1201 in the inner cavity of the support platform 120 can drive the lighting device 130 to rotate. Through the rotation of the lighting device 130, the situation around the railway can be viewed. At the same time, a rotating support assembly 200 is provided at the output end of the motor 1201. At this time, the rotating support assembly 200 will rotate simultaneously with the rotating support assembly 200, and the rotation of the rotating support assembly 200 will drive the adjustment assembly 400 to rotate. At this time, the focusing lens assembly 300 will be driven to rotate synchronously so that it can cooperate with the lighting device 130 to work.

[0019] Taking into account that when the lighting equipment is illuminating in the dark, the light of the lighting equipment is relatively scattered, and some foreign objects that are difficult to see on the rails are easily missed during the inspection process. If the missed foreign objects are large or have sharp edges, the wheels may crush the foreign objects when the train is running at high speed, causing wheel wear and deformation, or even causing derailment accidents, seriously threatening the safety of train operation and endangering the lives of passengers and cargo. Therefore, by connecting the focusing lens assembly 300 with the adjustment assembly 400, and setting the support assembly 200 at the output end of the motor 1201 to rotate with the lighting equipment 130, since the adjustment assembly 400 is set on the top of the rotating support assembly 200, the focusing lens assembly 300 can be rotated synchronously with the lighting equipment 130 during the rotation process, so that the light of the lighting equipment 130 is converged into a more concentrated and powerful light beam when passing through the focusing lens assembly 300, thereby clearly illuminating the rails, sleepers and surrounding facilities, so that the high-definition camera in the fuselage main body 100 can quickly record, avoiding the situation where foreign objects on the rails are missed due to poor light.

[0020] At the same time, considering that on mountain railways, drones fly to low-lying areas such as valleys, and the surrounding terrain blocks light, it is necessary to adjust the lens to allow more light to converge on low targets to ensure sufficient lighting in the inspection area. On sections with large terrain undulations, the lens position is adjusted in real time according to the height difference to ensure that the light can evenly illuminate railway facilities at different heights. Therefore, by connecting the focusing lens assembly 300 to the adjustment assembly 400, the adjustment assembly 400 can flexibly adjust the distance between the focusing lens assembly 300 and the lighting device 130 according to actual inspection needs. When it is necessary to illuminate a small range of targets at a closer distance and more accurately, such as checking the specific conditions of tiny foreign objects or fasteners on the rails, the adjustment assembly 400 can move the focusing lens assembly 300 closer to the lighting device 130, reducing the light focusing range and enhancing the local light intensity. When it is necessary to illuminate a larger area, such as checking the overall situation of the valley, the adjustment assembly 400 moves the focusing lens assembly 300 away from the lighting device 130 to expand the light coverage range.

[0021] On the basis of the above, the specific structure is disclosed in detail: like Figure 5-7 As shown, in order for the rotating support assembly 200 to drive the adjustment assembly 400 and the focusing lens assembly 300 to rotate, so that the focusing lens assembly 300 can focus the light emitted by the lighting device 130, it is necessary to further disclose the parts of the rotating support assembly 200. Therefore, the rotating support assembly 200 includes a connecting frame 210 fixedly connected to the output end surface of the motor 1201, the top of the connecting frame 210 is located below the lighting device 130, and the adjusting assembly 400 is provided on the top of the connecting frame 210. By fixing the connecting frame 210 to the output end surface of the motor 1201 and arranging it below the lighting device 130, in the process of the motor 1201 driving the lighting device 130 to rotate, the connecting frame 210 can be driven to rotate at the same time. At this time, the rotation of the connecting frame 210 can synchronously drive the adjusting assembly 400 to move accordingly.

[0022] like Figure 7-8 As shown, in order to enable the adjustment assembly 400 to rotate simultaneously with the connecting frame 210, it is necessary to further disclose the parts of the adjustment assembly 400. Therefore, the adjustment assembly 400 includes a limiting rail 460 fixedly connected to the top of the connecting frame 210, and a slide rail is provided on the top of the limiting rail 460; The inner wall of the slide rail is slidably connected to a limit block 4501 , and one end of the limit block 4501 away from the limit rail 460 is fixedly connected to a support rod 450 ; A focusing lens assembly 300 is provided at the end of the support rod 450. By fixing the limiting rail 460 to the top of the connecting frame 210, the connecting frame 210 can support the limiting rail 460. At the same time, the limiting block 4501 slides on the inner wall of the limiting rail 460, so that the limiting block 4501 can drive the support rod 450 to slide above the limiting rail 460. At the same time, the movement of the support rod 450 can drive the focusing lens assembly 300 to approach or move away from the lighting device 130.

[0023] like Figure 3-5 As shown, in order to enable the focusing lens assembly 300 to focus the light emitted by the lighting device 130, it is necessary to further disclose the parts of the focusing lens assembly 300. Therefore, the focusing lens assembly 300 includes a protection frame 310 fixedly connected to the end of the support rod 450, and a lens 320 is fixedly connected to the inner cavity of the protection frame 310; The lens 320 is located on the surface of the lighting device 130 . By connecting the protection frame 310 to the support rod 450 , the support rod 450 can support the protection frame 310 , so that the lens 320 is located on the surface of the lighting device 130 .

[0024] like Figure 7-8 As shown, in order to allow the limiting block 4501 to slide on the inner wall of the limiting track 460, the top of the support rod 450 is fixedly connected to the support frame 440, and the end of the support frame 440 away from the support rod 450 is fixedly connected to the rack 430, and the outer edge of the rack 430 is meshed with the driving gear 420; The driving gear 420 rotates above the driving gear 420, and the rotation of the driving gear 420 can drive the rack 430 to slide. Since the rack 430 is connected to the support rod 450 through the support frame 440, and the limit block 4501 at the bottom of the support rod 450 slides on the inner wall of the limit track 460, this limits the movement direction of the support rod 450 so that it can only move along the direction specified by the limit track 460. Since the rack 430 is connected to the support rod 450, this limiting effect also indirectly ensures the stability of the rack 430 during movement, reducing the possibility of its displacement perpendicular to the direction of movement.

[0025] like Figure 7-8 As shown, in order to enable the driving gear 420 to rotate and to ensure stable rotation of the driving gear 420, the surface of the connecting frame 210 is fixedly connected to the motor bracket 410, the inner cavity of the motor bracket 410 is fixedly connected to the driving motor, and the output end of the driving motor is fixedly connected to the surface of the driving gear 420; The end of the driving gear 420 away from the motor bracket 410 rotates on the surface of the connecting frame 210. The driving motor in the inner cavity of the motor bracket 410 can drive the driving gear 420 to rotate. At this time, the end of the driving gear 420 away from the motor bracket 410 is rotatably connected to the connecting frame 210, so that the driving gear 420 remains stable during the rotation process.

[0026] like Figure 7 As shown, in order to ensure that the support rod 450 can remain stable during the process of driving the protection frame 310 to move forward or backward, the end of the protection frame 310 away from the support rod 450 is fixedly connected to the rack 430; The two ends of the back of the protection frame 310 are respectively connected to the support rod 450 and the rack 430. By connecting the back of the protection frame 310 to the rack 430 and the support rod 450, the protection frame 310 can be supported, and the lens 320 in the inner cavity of the protection frame 310 can be supported at the same time.

[0027] like Figure 5-6 As shown, considering that the focusing lens assembly 300 and the adjustment assembly 400 are supported only by the connection between the connecting frame 210 and the output end surface of the motor 1201, the strength and stability of the connecting frame 210 are extremely high. Therefore, a slider 220 is fixedly connected to the bottom of the connecting frame 210, and an annular slide rail 230 is fixedly connected to the top of the fuselage body 100; A track is provided at the top of the annular slide rail 230, and the inner wall of the track is slidably connected to the surface of the slider 220. By adding the sliding connection between the slider 220 and the annular slide rail 230, the connecting frame 210 can support the focusing lens assembly 300 and the adjustment assembly 400 not only with the help of the connecting force of the output end of the motor 1201, but also by relying on the sliding support of the slider 220 in the track of the annular slide rail 230, which greatly disperses the supporting force, effectively reduces the excessive requirements on the connecting frame 210, and enhances the stability and reliability of the entire support structure.

[0028] like Figure 1 As shown, considering that the railway will not stop transportation due to weather reasons during the rainy season, it is necessary to protect the focusing lens assembly 300 and the adjustment assembly 400. Therefore, a protective frame 500 is fixedly connected to the top of the fuselage main body 100. The protective frame 500 is made of transparent acrylic material. By setting the protective frame 500, the focusing lens assembly 300 and the adjustment assembly 400 can be protected on rainy days.

[0029] In summary, the workflow of the present invention is: During night inspections, the inspection drone is first turned on, and the four propellers 110 fixedly connected to the top of the fuselage body 100 start to operate, generating strong lift, which steadily lifts the drone and maintains the flight state, so that it can move along the railway. Then, the motor 1201 in the inner cavity of the support platform 120 can drive the lighting device 130 to rotate. Through the rotation of the lighting device 130, the situation around the railway can be viewed. At the same time, when the motor 1201 drives the lighting device 130 to rotate, it can also drive the connecting frame 210 to rotate. At this time, the motor bracket 410 and the limiting track 460 located on the surface of the connecting frame 210 will rotate synchronously, so that the limiting block 4501 sliding on the inner wall of the limiting track 460 drives the support rod 450 to rotate the protective frame 310. The rotation of the protective frame 310 will drive the lens 320 in the inner cavity to rotate, so that the light of the lighting device 130 passes through the lens 320 and is gathered into a more concentrated and powerful light beam. If you need to reduce the focus range of light or expand the lighting range; The driving motor in the inner cavity of the motor bracket 410 can drive the driving gear 420 to rotate, and the rotation of the driving gear 420 can drive the rack 430 to slide. Since the rack 430 is connected to the support rod 450 through the support frame 440, and the limit block 4501 at the bottom of the support rod 450 slides on the inner wall of the limit track 460, this limits the movement direction of the support rod 450 so that it can only move along the direction specified by the limit track 460. At this time, the rack 430 and the support rod 450 will synchronously drive the protective frame 310 to approach or move away from the lighting device 130.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
