Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles, and in particular, relates to an unmanned aerial vehicle inspection system and method. Background Art

[0002] Inspection work is crucial in many industrial fields and infrastructure maintenance. Traditional inspection methods mostly rely on manual labor, which has problems such as low efficiency, high cost, and difficulty in reaching certain dangerous or complex environments. The emergence of drone inspection technology has alleviated these problems to a certain extent.

[0003] A search of CN117141775A disclosed a UAV inspection system. When the UAV stops on the apron, after the support rod is detached from the apron, the apron can automatically level under the action of the gravity of the balance ball to facilitate the take-off of the UAV. After the UAV takes off, the apron can also automatically level under the action of the gravity of the balance ball to facilitate the landing of the UAV.

[0004] When a drone is being recovered and stopped, the helipad can only park and resupply one drone. When multiple drones need to be parked and resupplyed, it cannot be done at the same time.

Because the baffles on both sides move the position distance, the extrusion limit blocks on both sides will be driven to move, so that the auxiliary parking plates on both sides will lose their limiting effect. At this time, the third spring will rebound and reset to drive the second slide column to move outward. The movement of the second slide column can drive the auxiliary parking plate to extend outward. After that, as the parking plate extends out of the inner frame, three drones can be parked at a time through the auxiliary parking plates on both sides, thereby improving the replenishment efficiency, thereby improving the efficiency of subsequent inspection work;

[0021] S4: When the shutdown plate moves upward, it will drive the push rod to move upward. At this time, the push rod will contact and squeeze the box cover. The squeezed box cover will rotate through the rotating shaft, and the rotation of the rotating shaft will drive the torsion spring to rotate. At the same time, the card plate at the other end of the box cover will move upward.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] According to the present invention, the first pull plate is first pulled outward to drive the positioning rod to move outward. At the same time, the second spring will be driven to stretch during the movement of the first pull plate. At this time, the outer wall of the positioning rod will be separated from the inner wall of the positioning hole, so that the extension plate will lose its limiting effect, and the support plate will be pulled to move in the left and right directions, driving the extension plates on the left and right sides to move. In this way, the area of ​​the inner frame is increased to provide parking space for multiple drones.

[0041] Embodiment 2:

[0042] The difference between the above embodiment and this embodiment is that: Figures 1 to 8 As shown, a drone inspection system and method, the opening and closing mechanism 32 includes a rotating hole opened on the inner side of the top of the fixed plate 311, the inner wall of the rotating hole is fixedly connected to a torsion spring 321, the end of the torsion spring 321 away from the inner wall of the rotating hole is fixedly connected to a rotating shaft 322, the outer wall of the rotating shaft 322 is rotatably arranged on the inner wall of the rotating hole, the outer wall of the rotating shaft 322 is fixedly connected to a box cover 323, the outer wall of the box cover 323 away from the rotating shaft 322 is fixedly connected to a clamping plate 324, the fixed plate 311 The outer wall is fixedly connected to a fixed frame 325, and a clamping column 326 is movably passed through the outer wall of the fixed frame 325.

The fourth spring 328 is fixedly connected to the outer wall of the fixed frame 325 at one end away from the second pull plate 327. The top of the baffle 315 is fixedly connected to a magnet 329, and the outer wall of the shutdown plate 3116 is fixedly connected to a push rod 3210.

[0043] Furthermore, extension slides identical to the extension plates 314 are provided on both sides of the box cover 323. The extension slides are two symmetrical structures distributed on the left and right sides of the box cover 323, and both are made of iron. By setting them as iron materials, it can be ensured that they can produce a magnetic limiting effect with the magnet 329.

[0044] Furthermore, the inner wall of the card hole opened on the outer wall of the card plate 324 is slightly larger than the outer wall of the card column 326, and the upper and lower ends of the outer wall of the card column 326 are opened with inclined surfaces. Through the opened inclined surfaces, the card plate 324 can be squeezed during the clamping process, thereby facilitating the clamping effect.

[0045] Furthermore, there are two magnets 329, which are symmetrically distributed on the top of the left and right baffles 315, so that the box cover 323 can be magnetically limited with the baffle 315, so that it can extend and move with it.

[0046] The present invention also discloses a method for using the drone inspection system:

[0047] S1: First, pull the first pull plate 318 outward to drive the positioning rod 317 to move outward. At the same time, the second spring 319 will be stretched during the movement of the first pull plate 318. At this time, the outer wall of the positioning rod 317 will be separated from the inner wall of the positioning hole 3110, so that the extension plate 314 will lose its limiting effect, and the support plate 316 will be pulled to move to the left and right sides, driving the extension plates 314 on the left and right sides to move, thereby increasing the area of ​​the inner frame to provide parking space for multiple drones;

[0048] S2: At this time, the positioning rod 317 will move to the position of the outermost positioning hole 3110, and the first pull plate 318 is released to drive the positioning rod 317 to be inserted into the inner wall of the positioning hole 3110 through the rebound of the second spring 319, and the positioning is completed;

[0049] S3: Starting motor 3111 drives screw rod 3112 to rotate, thereby driving threaded sleeve 3113 to move upward, and limiting the threaded sleeve 3113 through limiting rod 3114 and limiting slide groove 3115. At this time, threaded sleeve 3113 will drive parking plate 3116 and auxiliary parking plate 3119 to move upward. Because the baffle plates 315 on both sides move the position distance, the extrusion limiting blocks 3120 on both sides will be driven to move, so that the auxiliary parking plates 3119 on both sides will lose their limiting effect. At this time, the third spring 3117 will rebound and reset to drive the second sliding column 3118 to move outward. The movement of the second sliding column 3118 can drive the auxiliary parking plates 3119 to extend outward. After that, as the parking plate 3116 extends out of the inner frame, three drones are parked at a time through the auxiliary parking plates 3119 on both sides, thereby improving the replenishment efficiency, thereby improving the efficiency of subsequent inspection work;

[0050] S4: When the shutdown plate 3116 moves upward, it will drive the push rod 3210 to move upward. At this time, the push rod 3210 will contact and squeeze the box cover 323. The squeezed box cover 323 will rotate through the rotating shaft 322, and the rotation of the rotating shaft 322 will drive the torsion spring 3221 to rotate. At the same time, the clamping plate 324 at the other end of the box cover 323 will move upward. At this time, the two sides of the box cover 323 will be magnetically limited by the magnets 329 and the baffles 315 on both sides, so as to ensure that the baffle 315 can move with it during its movement. In this way, the entire parking and storage process does not require manual intervention, which is more convenient to use.

[0051] The implementation principle of a drone inspection system and method of the present embodiment is as follows: when it is necessary to park multiple drones, the first pull plate 318 is first pulled outward to drive the positioning rod 317 to move outward. At the same time, the second spring 319 will be driven to stretch during the movement of the first pull plate 318. At this time, the outer wall of the positioning rod 317 will be separated from the inner wall of the positioning hole 3110, so that the extension plate 314 will lose its limiting effect, and then the support plate 316 can be pulled to move to the left and right sides, thereby driving the extension plates 314 on the left and right sides to move, and the movement of the extension plates 314 can bring The first sliding column 313 is driven to move outward, and at the same time, the first spring 312 is driven to stretch during the movement of the first sliding column 313, and then the baffle 315 is driven to extend to the left and right sides during the movement of the extension plate 314, so that the area of ​​the inner frame can be increased to provide parking space for multiple drones. After the positioning rod 317 is moved to the position of the outermost positioning hole 3110, the first pulling plate 318 is released and the positioning rod 317 is inserted into the inner wall of the positioning hole 3110 through the rebound of the second spring 319 to complete the positioning, and then the motor 3111 is started, and its output end drives the screw rod 3112 to rotate, so that The threaded sleeve 3113 is driven to move upward, and the threaded sleeve 3113 is limited by the limiting rod 3114 and the limiting slide groove 3115. At this time, the threaded sleeve 3113 will drive the parking plate 3116 and the auxiliary parking plate 3119 to move upward. Because the baffles 315 on both sides have moved a certain distance, the extrusion limiting blocks 3120 on both sides will be driven to move, so that the auxiliary parking plates 3119 on both sides will lose their limiting effect. At this time, the third spring 3117 will rebound and reset to drive the second sliding column 3118 to move outward, and the auxiliary parking plates 3119 can be driven outward by the movement of the second sliding column 3118. Extend, and then as the parking plate 3116 extends out of the inner frame, three UAVs can be parked at a time through the auxiliary parking plates 3119 on both sides, thereby improving the supply efficiency, thereby improving the efficiency of subsequent inspection work; when there is no need to park multiple UAVs, as the auxiliary parking plate 3119 moves downward, it will contact the baffles 315 on both sides and then be squeezed by them, and then shorten inward, and then when it moves to the position of the extrusion limit block 3120, it will be squeezed by the extrusion limit block 3120 and shortened inward again, and then the auxiliary parking plate 3119 will stop at the extrusion limit block 3120, and will always be subject to its limiting squeezing effect.

[0052] When the stop plate 3116 moves upward, it will drive the push rod 3210 to move upward. At this time, the push rod 3210 will contact and squeeze the box cover 323. The squeezed box cover 323 will rotate through the rotating shaft 322. The rotation of the rotating shaft 322 can drive the torsion spring 321 to rotate. At the same time, the clamping plate 324 at the other end of the box cover 323 will move upward, so that the bottom end of the inner wall of the clamping hole of the outer wall of the clamping plate 324 will squeeze the bottom end inclined surface of the clamping column 326. The squeezed clamping column 326 will drive the second pull plate 327 to move outward. During the movement of the second pull plate 327, the fourth spring 328 is driven to stretch until the outer wall of the clamping column 326 is separated from the clamping hole formed on the outer wall of the clamping plate 324, so that the box cover 323 is flipped and unfolded, thereby presenting an open state. At the same time, the two sides of the box cover 323 can move and extend following the movement of the extension plate 314. At this time, the two sides of the box cover 323 will be magnetically limited by the magnets 329 and the baffles 315 on both sides, thereby ensuring that it can move along during the movement of the baffle 315. In this way, the entire parking and storage process does not require manual intervention, which is more convenient to use.

9. The unmanned aerial vehicle inspection system according to claim 1, characterized in that: An unmanned aerial vehicle inspection system as described in any one of claims 1 to 8, wherein the method for operating the underwater component immersion anti-corrosion detection device comprises the following steps: S1: First, the first pull plate (318) is pulled outward, thereby driving the positioning rod (317) to move outward. At the same time, the second spring (319) will be driven to stretch during the movement of the first pull plate (318). At this time, the outer wall of the positioning rod (317) will be separated from the inner wall of the positioning hole (3110), so that the extension plate (314) will lose its limiting effect, and the support plate (316) will be pulled to move to the left and right sides, driving the extension plates (314) on the left and right sides to move, thereby increasing the area of ​​the inner frame to provide parking space for multiple drones; S2: At this time, the positioning rod (317) will move to the position of the outermost positioning hole (3110), and the first pull plate (318) will be released to drive the positioning rod (317) to be inserted into the inner wall of the positioning hole (3110) through the rebound of the second spring (319), thereby completing the positioning; S3: The motor (3111) is started to drive the screw rod (3112) to rotate, thereby driving the threaded sleeve (3113) to move upward, and the threaded sleeve (3113) is limited by the limit rod (3114) and the limit slide groove (3115). At this time, the threaded sleeve (3113) will drive the stop plate (3116) and the auxiliary parking plate (3119) to move upward. Since the baffles (315) on both sides move the position distance, the extrusion limit blocks (3120) on both sides will be driven to move upward. The auxiliary parking plates (3119) on both sides will lose their limiting function, and the third spring (3117) will rebound and reset to drive the second slide column (3118) to move outward. The movement of the second slide column (3118) can drive the auxiliary parking plates (3119) to extend outward. Then, as the parking plate (3116) extends out of the inner frame, three drones can be parked at a time through the auxiliary parking plates (3119) on both sides, thereby improving the replenishment efficiency, thereby improving the efficiency of subsequent inspection work; S4: When the stop plate (3116) moves upward, it will drive the push rod (3210) to move upward. At this time, the push rod (3210) will contact and squeeze the box cover (323). The squeezed box cover (323) will rotate through the rotating shaft (322), and the rotation of the rotating shaft (322) will drive the torsion spring (3221) to rotate. At the same time, the clamping plate (324) at the other end of the box cover (323) will move upward. At this time, the two sides of the box cover (323) will be magnetically limited by the baffles (315) on both sides through the magnets (329), so as to ensure that the baffles (315) can move with it during the movement. In this way, no manual intervention is required during the entire parking and storage process, which is more convenient to use.
