Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) aerial surveying technology, and in particular to a UAV aerial surveying camera and its usage method. Background Technology

[0002] In airport engineering, pavement quality inspection and evaluation are crucial steps. Among these, pavement compartment mapping and corner elevation measurement are essential. Currently used techniques such as point-by-point leveling and laser scanning are inefficient, labor-intensive, and lack representativeness, necessitating technological innovation. These methods suffer from the following shortcomings: Inefficiency: Point-by-point leveling requires measuring each point individually, which is time-consuming and labor-intensive. While laser scanning can quickly acquire data, data processing and analysis still require time and specialized technical support. Lack of Data Representativeness: Measuring each point on the pavement during compartment mapping and corner elevation measurement may not fully represent the overall pavement quality, meaning that localized omissions or deviations may occur when assessing pavement quality. Accuracy and Precision: Existing technologies for data measurement and processing are susceptible to factors such as equipment precision, human error, and environmental conditions, affecting the accuracy and precision of the measurement data. Therefore, using drones for aerial surveying is gradually replacing traditional surveying methods. Compared with manual ground surveying, this method can be several times more efficient. It has advantages such as being less affected by weather, low cost, and being mobile and convenient, providing strong technical support for quickly completing airport pavement renovation tasks. However, existing drone aerial surveying devices have at least the following shortcomings: the fuselage and wings cannot be quickly disassembled and assembled, which is not conducive to the carrying and storage of drones.

[0003] The detection modules installed on UAV aerial surveying devices are relatively fixed and inconvenient to replace. If the installed detection modules have a single function, the UAV aerial surveying device cannot perform complex detection functions. If various functional detection modules are installed on the UAV aerial surveying device, it will increase the weight of the UAV aerial surveying device, affect the endurance of the UAV aerial surveying device, and be detrimental to the actual use of the UAV aerial surveying device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drone aerial surveying camera and its usage method.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0015] The present invention also provides a method for using the above-mentioned UAV aerial surveying camera, comprising the following steps:

[0016] S1. Install surveying equipment:

[0017] Pull the lever to separate the locking block from the toothed ring and release the lock.

[0018] Align the rotating seat with the threaded cylinder and turn the rotating seat to screw it into the threaded cylinder.

[0019] During rotation, the limiting ring and limiting groove restrict the range of the rotating seat to ensure stable installation.

[0020] Once the rotating seat is in place, release the pull rod to allow it to reset. The locking block will then engage with the tooth groove of the gear ring, restricting the movement of the rotating seat.

[0021] Ensure the surveying equipment is stably mounted on the mounting frame to guarantee stability during flight.

[0022] S2. Replace the surveying equipment:

[0023] Pull the lever to release the lock and separate the locking block from the gear ring.

[0024] Turn the rotating seat to unscrew the threaded cylinder.

[0025] Align the surveying device to be replaced with the mounting mechanism, and then insert it into the mounting bracket.

[0026] Ensure that the surveying equipment is securely installed and not loose or detached.

[0027] Release the lever to allow it to reset; the locking block will engage with the toothed groove of the gear ring, ensuring the fixed position of the surveying device.

[0028] S3. Disassembling and assembling the fuselage and wings:

[0029] When the power is cut off, the electromagnet loses its magnetism, thus releasing the attraction of the sliding seat.

[0030] Pushing the push block moves the sliding seat, which in turn pulls the control block via the pull rope, causing it to move within the insertion block.

[0031] The inclined surface of the control block no longer presses against the control rod, causing the blocks to move closer to each other through the action of spring two, disengaging from the slot, and allowing the insert block to move out freely.

[0032] Separate the fuselage and wings, disassemble, and perform maintenance or replacement.

[0033] S4. Connect the fuselage and wings:

[0034] Align the fuselage and wings, ensuring the insert is inserted into the slot.

[0035] Release the push block, allowing it to reset under the action of spring four, and the pull rope will no longer pull the control block.

[0036] Spring three resets the control block, causing its inclined surface to press against the control rod, and the locking blocks are inserted into the locking slots respectively, stably connecting the fuselage and the wing.

[0037] When electricity is applied, the electromagnet becomes magnetic, attracting the sliding seat and securing the connection between the fuselage and the wing.

[0038] The present invention has the following beneficial effects:

[0039] Flexible replacement of surveying equipment: Through the installation mechanism, the surveying equipment can be flexibly replaced according to different surveying tasks. This allows the UAV to adapt to various surveying needs without the need to install surveying equipment with different functions, thereby avoiding increasing the weight of the UAV and ensuring flight endurance.

[0040] Installation stability: The surveying device is installed on the mounting frame through the installation mechanism, and stable installation is achieved by using components such as locking blocks, rotating seats, and limit rings. This ensures the stability of the surveying device in flight, avoids accidental detachment or unintentional rotation, and protects the integrity and performance of the UAV device and surveying equipment.

[0041] Quick assembly and disassembly: The fuselage and wings of the drone are connected by a mechanism that enables quick assembly and disassembly. Through the cooperation of components such as push blocks, locking blocks, and insert blocks, the fuselage and wings can be easily disassembled and connected. This design makes maintenance more convenient and saves time and labor costs.

[0042] Stable connection: When the fuselage is connected to the wing, the stability of the connection is ensured through the coordinated action of the control block, the locking block and the insert block. The inclined surface of the control block presses against the control rod, causing the locking blocks to move away from each other until they are inserted into the locking slot, thereby fixing the connection between the fuselage and the wing.

[0043] Enhanced safety: The use of electromagnets can increase the safety of the connection mechanism. When the power is off, the electromagnet loses its magnetism, allowing the slide to slide freely and facilitating the disassembly of the wing. When the power is on, it generates magnetism, attracting the slide to fix the connection between the fuselage and the wing, thus improving flight safety. Attached Figure Description

[0065] Reference Figure 6-9 The snap-fit ​​assembly 61 includes a plug 611, two snap-fit ​​blocks 612, a slot 613, and two slots 614. The plug 611 is fixed on the fuselage 21 and has a hollow structure. The two snap-fit ​​blocks 612 are slidably mounted on the plug 611 and extend to the outside of the plug 611. The slot 613 is opened on the wing 22, and the two slots 614 are opened on the groove wall of the slot 613.

[0071] The present invention also provides a method for using the above-mentioned UAV aerial surveying camera, comprising the following steps:

[0072] S1. Install surveying equipment:

[0073] Pull the lever to separate the locking block from the toothed ring and release the lock.

[0074] Align the rotating seat with the threaded cylinder and turn the rotating seat to screw it into the threaded cylinder.

[0075] During rotation, the limiting ring and limiting groove restrict the range of the rotating seat to ensure stable installation.

[0076] Once the rotating seat is in place, release the pull rod to allow it to reset. The locking block will then engage with the tooth groove of the gear ring, restricting the movement of the rotating seat.

[0077] Ensure the surveying equipment is stably mounted on the mounting frame to guarantee stability during flight.

[0078] S2. Replace the surveying equipment:

[0079] Pull the lever to release the lock and separate the locking block from the gear ring.

[0080] Turn the rotating seat to unscrew the threaded cylinder.

[0081] Align the surveying device to be replaced with the mounting mechanism, and then insert it into the mounting bracket.

[0082] Ensure that the surveying equipment is securely installed and not loose or detached.

[0083] Release the lever to allow it to reset; the locking block will engage with the toothed groove of the gear ring, ensuring the fixed position of the surveying device.

[0084] S3. Disassembling and assembling the fuselage and wings:

[0085] When the power is cut off, the electromagnet loses its magnetism, thus releasing the attraction of the sliding seat.

[0086] Pushing the push block moves the sliding seat, which in turn pulls the control block via the pull rope, causing it to move within the insertion block.

[0087] The inclined surface of the control block no longer presses against the control rod, causing the blocks to move closer to each other through the action of spring two, disengaging from the slot, and allowing the insert block to move out freely.

[0088] Separate the fuselage and wings, disassemble, and perform maintenance or replacement.

[0089] S4. Connect the fuselage and wings:

[0090] Align the fuselage and wings, ensuring the insert is inserted into the slot.

[0091] Release the push block, allowing it to reset under the action of spring four, and the pull rope will no longer pull the control block.

[0092] Spring three resets the control block, causing its inclined surface to press against the control rod, and the locking blocks are inserted into the locking slots respectively, stably connecting the fuselage and the wing.

[0093] When electricity is applied, the electromagnet becomes magnetic, attracting the sliding seat and securing the connection between the fuselage and the wing.

[0094] The specific working principle of this invention is as follows:

[0095] This invention utilizes unmanned aerial vehicle (UAV) aerial surveying to conduct surveys of airport roads, such as... Figure 1 As shown, Figure 1 Point A in the diagram represents the takeoff and landing point of drone device 2. Figure 1 The dashed line in the diagram represents the survey route of UAV device 2. Figure 1 The shaded area in the figure represents the survey range of UAV device 2. Ground station 1 is the flight control terminal of UAV device 2. It is a control system that sends various control commands to UAV device 2, plans flight missions, and monitors various flight parameters. Through the operation of ground station 1, the flight and trajectory planning of UAV device 2 can be completely controlled, and the flight status of UAV device 2 can be monitored in real time to ensure the safe take-off and landing of UAV device 2 and ultimately complete the aerial photography mission smoothly. Ground station 1 is easy to operate and does not require complicated operation procedures. Just give the aerial photography range, and you can complete the planning and control the flight of UAV device 2 through simple operation. Specifically, the specific control method of ground station 1 for UAV device 2 is existing technology. Its working principle is not considered as an innovative part of this technical solution and is not shown in the figure. It will not be elaborated on here.

[0096] A surveying device 3 is mounted on the bottom of the UAV device 2. The surveying device 3 includes surveying equipment such as a visible light camera, a thermal imaging camera, and a multispectral camera, which can be flexibly replaced according to the surveying task. The surveying device 3 is mounted on the mounting frame 4 via a mounting mechanism. When installing the surveying device 3, the operator first pulls the lever 523, causing the lever 523 to move the locking block 524 until the locking block 524 separates from the gear ring 521. Without the limiting effect of the locking block 524, the rotating seat 515 can rotate freely relative to the fixed seat 512. Then, the operator aligns the rotating seat 515 with the threaded cylinder 51. 1. Tighten the rotating seat 515 so that it screws into the threaded cylinder 511. During the rotation of the rotating seat 515, the limiting ring 513 and the limiting groove 514 limit the rotation of the rotating seat 515, allowing relative rotation between the rotating seat 515 and the fixed seat 512, and preventing the rotating seat 515 from falling off the fixed seat 512. After the rotating seat 515 is installed in place, the operator releases the pull rod 523. Under the action of the spring 525, the pull rod 523 will return to its original position, and the locking block 524 will also return to its original position and engage with one of the tooth grooves on the gear ring 521. 21 and locking block 524 limit the rotation seat 515 to prevent the rotation seat 515 from rotating under non-human action, and ensure the stability of the surveying device 3 on the mounting frame 4. Based on the above process, the staff can replace the surveying device 3 through the installation mechanism. The operation is convenient, so that the UAV device 2 can perform various surveying tasks without installing various functions of the surveying device 3 on the UAV device 2, avoiding excessive weight of the UAV device 2 and ensuring the endurance of the UAV device 2.

[0097] For the unmanned aerial vehicle (UAV) device 2, its fuselage 21 and wing 22 can be quickly assembled and disassembled through a connecting mechanism. When disassembling the wing 22, the operator first de-energizes the electromagnet 647. When the electromagnet 647 is de-energized, it loses its magnetism and no longer attracts the sliding seat 643 made of magnetic material. Without the restriction of the electromagnet 647, the sliding seat 643 can slide freely. Then, the operator pushes the push block 644. When the push block 644 moves, it can drive the sliding seat 643 to move. When the sliding seat 643 moves, it can be pulled by the rope 6 46 Pull the control block 631 to move it within the insert block 611. When the control block 631 moves, its inclined part no longer presses against the two control rods 632. Without the pressure of the control block 631, the two locking blocks 612 will move closer to each other under the action of the two springs 622 until the two locking blocks 612 move out of the two slots 614 respectively. Without the restriction of the two locking blocks 612, the insert block 611 can be moved out of the slot 613, which facilitates the separation of the fuselage 21 from the wing 22.

[0098] During the installation of the fuselage 21 and wing 22, the operator first pushes the push block 644 as described above, causing both locking blocks 612 to retract into the insert block 611. Then, the fuselage 21 is connected to the wing 22. At this point, the insert block 611 will insert into the slot 613. Next, the operator releases the push block 644, allowing it to reset under the action of spring four 645. When the push block 644 resets, the pull rope 646 no longer pulls on the control block 631. At this time, the control block 631 will reset under the action of spring three 635. When the control block 631 is reset, the inclined surface of the control block 631 will press the two control rods 632, causing the two locking blocks 612 to move away from each other until the two locking blocks 612 are inserted into the two locking slots 614 respectively. Finally, the operator energizes the electromagnet 647. When the electromagnet 647 is energized, it can generate magnetism and attract the sliding seat 643, thereby fixing the position of the sliding seat 643 and preventing the sliding seat 643 from moving under non-human action, thus ensuring the connection stability between the fuselage 21 and the wing 22.

[0099] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
