Description

Technical Field

[0001] This utility model relates to the field of remote sensing imaging devices, and in particular to a remote sensing imaging device. Background Technology

[0002] In the field of remote sensing imagery, drones have become an important platform for acquiring remote sensing data due to their advantages such as flexibility, ease of operation, and relatively low cost. Currently, most drones used for remote sensing imagery are equipped with built-in cameras. This integrated design simplifies the equipment structure to some extent and facilitates rapid deployment.

[0003] However, the hardware performance of the cameras built into these drones is often significantly insufficient due to cost constraints and other factors. Specifically, the image sensor resolution and lens optical performance of the cameras are difficult to reach professional-grade levels, resulting in limitations in detail, clarity, and color reproduction of the captured remote sensing images. This makes it difficult to meet the high image quality requirements of applications such as high-precision surveying, precision agricultural monitoring, and cultural relic protection surveying. Furthermore, the shooting devices on existing drones lack flexibility in angle adjustment, with most only allowing for limited rotation or fixed-angle shooting. This makes it difficult to make comprehensive and precise three-dimensional angle adjustments according to actual shooting needs, limiting the shooting range and the diversity of image acquisition.

[0004] Therefore, how to provide a remote sensing image capturing device that can be equipped with high-performance shooting equipment and achieve flexible three-dimensional angle adjustment in order to improve the shooting quality and applicability of remote sensing images has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] This utility model provides a remote sensing image capturing device, including a drone. The lower end of the drone is provided with a vertical rotating connecting shaft, which is connected to a first rotating component. The bottom end of the rotating connecting shaft is fixedly connected to a hoisting frame, which is fixedly equipped with a vertical hoisting rod. The hoisting rod is connected to a horizontal mounting frame, which is connected to a second rotating component. The mounting frame suspends a tray assembly, which is connected to a camera. The tray assembly is connected to a third rotating component. The output axis of the first rotating component is the z-axis, the output axis of the second rotating component is the y-axis, and the output axis of the third rotating component is the z-axis. The z-axis, y-axis, and x-axis are perpendicular to each other.

[0007] Furthermore, the hoisting frame includes multiple hoisting support pipes and a plug-in fastener. The plug-in fastener has multiple plug holes formed on it, and the multiple hoisting support pipes are plugged into and fastened into the plug holes and placed on the same plane.

[0008] Furthermore, the hoisting rod is hoisted onto one of the hoisting support pipes by a first hoisting component. The mounting frame includes a horizontally placed first mounting pipe and second mounting pipes vertically arranged at both ends of the first mounting pipe along the y-axis. The first mounting pipe is hoisted onto the hoisting rod by a second hoisting component. The second hoisting component is provided with a horizontal rotating shaft, which is connected to the power output end of the second rotating assembly.

[0009] Furthermore, the second lifting component includes an upper lifting component mounted on a lifting rod and a lower lifting component mounted on a first mounting tube. The upper lifting component and the lower lifting component are hinged to form a hinge position. The horizontal rotating shaft is located at the hinge position. The second rotating assembly drives the lower lifting component to rotate on the upper lifting component, thereby driving the first mounting tube to rotate.

[0010] Furthermore, the pallet assembly includes a horizontally placed load-bearing tube, a third lifting member vertically fixed to both ends of the load-bearing tube, and a flip shaft connector at the end of the second mounting tube. The third lifting member and the flip shaft connector are connected through a flip shaft. The flip shaft is connected to the power output end of the third rotating assembly. The third rotating assembly drives the third lifting member to rotate, thereby causing the load-bearing tube to rotate.

[0011] Furthermore, the first rotating assembly includes a first driven gear disposed on a rotating connecting shaft, a first motor mounted on a hoisting support pipe, a first driving gear connected to the output shaft of the first motor, and a first toothed belt that engages with the first driving gear and the first driven gear.

[0012] Furthermore, the second rotating assembly includes a second driven gear disposed on a horizontal rotating shaft, a second motor mounted on a hoisting rod, a second driving gear connected to the output shaft of the second motor, and a second toothed belt that engages with the second driving gear and the second driven gear.

[0013] Furthermore, the third rotating assembly includes a third driven gear disposed on the flipping shaft, a third motor mounted on the second mounting tube, a third driving gear connected to the output shaft of the third motor, and a third toothed belt that engages with the third driving gear and the third driven gear.

[0014] Furthermore, the load-bearing pipe is fitted with a connecting ring, and a load-bearing plate is fitted on the connecting ring. The bottom of the camera is provided with a threaded hole, and the load-bearing plate is fastened to the camera by screws.

[0015] Furthermore, the end of the hoisting branch pipe is inserted tightly into the inherent ground support frame.

The device drives related components to rotate around the mutually perpendicular z-axis, y-axis and x-axis through the first, second and third rotating components, respectively, forming a complete three-dimensional rotation system. It can enable the camera to rotate 360 ​​degrees horizontally, adjust the pitch angle or tilt angle, and greatly improve the shooting performance.

[0018] 2. This utility model uses an external camera as the shooting device, which provides higher shooting quality compared to traditional webcams. The external camera can be flexibly selected from professional-grade equipment according to actual shooting needs. These cameras are often equipped with larger image sensors, which can capture more light information, effectively reduce noise, and improve image clarity and detail.

[0019] 3. This utility model features a robust and lightweight structural design, facilitating easy assembly and maintenance, and ensuring the stability and reliability of the device's operation.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1 This embodiment of a remote sensing image capturing device includes a drone device 1. The drone device 1 has a vertical rotating connecting shaft 701 at its lower end. The rotating connecting shaft 701 is connected to a first rotating component 7. The bottom end of the rotating connecting shaft 701 is fixedly connected to a hoisting frame 2. The hoisting frame 2 is fixedly hoisted with a vertical hoisting rod 3. The hoisting rod 3 is connected to a horizontal mounting frame 4. The mounting frame 4 is connected to a second rotating component 8. The mounting frame 4 hoists a tray assembly 5. The tray assembly 5 is connected to a camera 6. The tray assembly 5 is connected to a third rotating component 9. The output axis of the first rotating component 7 is the z-axis, the output axis of the second rotating component 8 is the y-axis, and the output axis of the third rotating component 9 is the z-axis. The z-axis, y-axis, and x-axis are perpendicular to each other.

[0031] As a key connecting component between the entire device and the UAV equipment 1, the rotating connecting shaft 701 not only bears the important responsibility of transmitting power from the UAV and ensuring that the device can fly stably with the UAV, but also provides a stable mounting foundation for the first rotating assembly 7. In the first rotating assembly 7, the first toothed belt 705 drives the rotating connecting shaft 701 and the entire structure below it to rotate freely 360 degrees around the z-axis.

[0032] Reference Figure 2 The hoisting frame 2 includes multiple hoisting support pipes 202 and a plug-in fastener 201. The plug-in fastener 201 has multiple plug-in holes, and the multiple hoisting support pipes 202 are plugged and fastened into the plug-in holes and placed on the same plane.

[0033] The hoisting rod 3 is hoisted onto one of the hoisting support pipes 202 by the first hoisting component 301. The mounting frame 4 includes a horizontally placed first mounting pipe 401 and second mounting pipes 402 vertically arranged at both ends of the first mounting pipe 401 along the y-axis. The first mounting pipe 401 is hoisted onto the hoisting rod 3 by the second hoisting component 404. The second hoisting component 404 is provided with a horizontal rotating shaft 801, which is connected to the power output end of the second rotating assembly 8.

[0034] Multiple lifting support pipes 202 are made of lightweight carbon fiber, which reduces the overall weight of the device while providing high strength and rigidity, enabling them to withstand significant tensile and compressive forces. This plug-in connection method facilitates quick disassembly and replacement of components during assembly and maintenance, improving the operability and maintenance efficiency of the device.

[0035] The first lifting component 301 is a ring-shaped clamp with a locking bolt. The ring-shaped clamp is fitted onto the lifting branch pipe 202 through its opening and then closed. The locking bolt can be used for tightening, reliably fixing the lifting rod 3 to the lifting branch pipe 202. The contact area between the ring-shaped clamp and the lifting branch pipe 202 can be equipped with an anti-slip rubber pad to increase friction and prevent displacement or shaking of the lifting rod 3 during operation.

[0036] The second lifting component 404 includes an upper lifting component 4041 disposed on the lifting rod 3 and a lower lifting component 4042 disposed on the first mounting tube 401. The upper lifting component 4041 and the lower lifting component 4042 are hinged to form a hinge position. The horizontal rotating shaft 801 is disposed at the hinge position. The second rotating assembly 8 drives the lower lifting component 4042 to rotate on the upper lifting component 4041, thereby driving the first mounting tube 401 to rotate.

[0037] The first mounting tube 401 and the second mounting tube 402 can also be hollow tubes made of aluminum alloy. The first mounting tube 401 is suspended on the lifting rod 3 by the second lifting member 404. The hinge between the upper lifting member 4041 and the lower lifting member 4042 of the second lifting member 404 is connected by a bearing, which allows the lower lifting member 4042 to rotate flexibly on the upper lifting member 4041, providing good conditions for the second rotating component 8 to drive the first mounting tube 401 to rotate around the y-axis.

[0038] Reference Figure 3 and Figure 4The pallet assembly 5 includes a horizontally placed load-bearing tube 501 and a third lifting member 504 vertically fixed at both ends of the load-bearing tube 501. The end of the second mounting tube 402 is provided with a flip shaft connector 403. The third lifting member 504 and the flip shaft connector 403 are connected by a flip shaft 901. The flip shaft 901 is connected to the power output end of the third rotating assembly 9. The third rotating assembly 9 drives the third lifting member 504 to rotate, thereby driving the load-bearing tube 501 to rotate.

[0039] Reference Figure 2 The first rotating assembly 7 includes a first driven gear 703 disposed on a rotating connecting shaft 701, a first motor 702 mounted on a hoisting support pipe 202, a first driving gear 704 connected to the output shaft of the first motor 702, and a first toothed belt 705 that is connected to the first driving gear 704 and the first driven gear 703.

[0040] Reference Figure 6 and Figure 7 The second rotating assembly 8 includes a second driven gear 803 disposed on a horizontal rotating shaft 801, a second motor 802 mounted on a hoisting rod 3, a second driving gear 804 connected to the output shaft of the second motor 802, and a second toothed belt 805 that is engaged with the second driving gear 804 and the second driven gear 803.

[0041] The second motor 802 of the second rotating assembly 8 is also a brushless DC motor. The second driving gear 804 is splined to the output shaft of the second motor 802. The second driven gear 803 is mounted on the horizontal rotating shaft 801 and is driven by the second driving gear 804 through the second toothed belt 805. The second toothed belt 805 is similar to the first toothed belt 705. When the second motor 802 starts, the second driven gear 803 and the horizontal rotating shaft 801 are driven to rotate through the second toothed belt 805, which in turn drives the lower hanging part 4042 and the first mounting tube 401 to rotate around the y-axis, thereby realizing the angle adjustment of the camera 6 in the vertical direction.

[0042] Reference Figure 5 The third rotating assembly 9 includes a third driven gear 903 disposed on the flip shaft 901, a third motor 902 mounted on the second mounting tube 402, a third driving gear 904 connected to the output shaft of the third motor 902, and a third toothed belt 905 that is connected to the third driving gear 904 and the third driven gear 903.

[0043] The third lifting component 504 is connected to the tilting shaft connector 403 via the tilting shaft 901. Both the third lifting component 504 and the tilting shaft connector 403 are equipped with bearings, providing a foundation for the third rotating component 9 to drive the tray assembly 5 to rotate around the x-axis. The third motor 902 is a DC geared motor, and the third driven gear 903 is mounted on the tilting shaft 901, transmitting power to the third driving gear 904 via the third toothed belt 905. When the third motor 902 is working, it drives the third driven gear 903 and the tilting shaft 901 to rotate via the third toothed belt 905, thereby causing the tray assembly 5 and the camera 6 to rotate around the x-axis, enabling flexible adjustment of the tilting angle of the camera 6.

[0044] Reference Figure 4 The load-bearing pipe 501 is inserted and fixedly provided with a connecting ring 502, and a load-bearing plate 503 is fixedly provided on the connecting ring 502. The bottom of the camera 6 is provided with a threaded hole, and the load-bearing plate 503 is fastened to the camera 6 by screws.

[0045] The connecting ring 502 is similar in structure to the first lifting component 301, and is a ring-shaped clamp with a locking bolt. The connecting ring 502 and the load-bearing plate 503 are fixedly connected as a single unit. The threaded hole at the bottom of the camera 6 is fastened to the mounting hole on the load-bearing plate 503 by screws. This connection method is simple and convenient to operate.

[0046] The end of the hoisting support pipe 202 is tightly connected to the inherent floor support frame 10. The floor support frame 10 can be easily disassembled when not in use, reducing space occupation and facilitating the storage of the device. The floor support frame 10 is made of lightweight aluminum alloy.

[0047] During operation, the moving connecting shaft, as the core connecting component, stably transmits the power of the drone, ensuring stable flight of the device along with the drone. At this time, the first rotating assembly 7 begins to operate. The first motor 702 drives the first driving gear 704 to rotate, which in turn drives the first driven gear 703 and the rotating connecting shaft 701 to rotate via the first toothed belt 705. This causes the rotating connecting shaft 701 and the following components—the lifting frame 2, lifting rod 3, mounting frame 4, tray assembly 5, and camera 6—to rotate 360 ​​degrees around the z-axis, achieving horizontal angle adjustment. During vertical angle adjustment, the second motor 802 drives the second driving gear 804, which in turn drives the second driven gear 803 and the horizontal rotating shaft 801 to rotate via the second toothed belt 805. This causes the lower lifting member 4042 of the second lifting member 404 to rotate on the upper lifting member 4041, thereby causing the first mounting tube 401 and the second mounting tubes 402 at both ends to rotate around the y-axis, allowing the camera 6 to complete the pitch angle change. When the tilt angle needs to be adjusted, the third rotating component 9 is activated. The third motor 902 drives the third driving gear 904, which in turn drives the third driven gear 903 and the tilting shaft 901 to rotate via the third toothed belt 905. This causes the third lifting component 504 to drive the load-bearing pipe 501 and the camera 6 to rotate around the x-axis, thus achieving flexible adjustment of the tilt angle. Throughout the process, the carbon fiber support pipe and the plug-in fixing component 201 of the lifting frame 2 provide stable support. The annular clamps of the first lifting component 301 and the connecting ring 502 firmly fix the lifting rod 3 and the connecting ring 502, respectively. The coordinated operation of all components allows the camera 6 to flexibly adjust its angle in three-dimensional space and accurately capture the required remote sensing images.

[0048] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
