Description

Technical Field

[0001] This utility model belongs to the field of remote sensing data acquisition technology, specifically a data acquisition device for remote sensing images. Background Technology

[0002] Remote sensing image data acquisition is a crucial technology in modern geographic information systems, environmental monitoring, and resource surveys. Its core lies in acquiring high-precision image data using equipment such as drones equipped with imaging devices. However, in practical applications, the stability and heat dissipation performance of the data acquisition device significantly impact image quality.

[0003] Existing remote sensing image data acquisition devices typically fix the imaging device to the bottom of the UAV through a simple mechanical connection structure. This design is susceptible to vibration and impact during UAV flight, resulting in insufficient stability of the imaging device and thus reducing the clarity and accuracy of the images. In addition, the imaging device generates a lot of heat during long-term operation. If it cannot be dissipated in time, it may overheat, affecting its normal operation and even shortening its service life.

[0004] Existing heat dissipation structures mostly use fixed fans or passive heat dissipation methods, which make it difficult to flexibly adjust the direction and intensity of heat dissipation according to actual needs. They have low heat dissipation efficiency and poor adaptability. At the same time, existing buffer and vibration reduction structures mostly rely on a single spring or rubber pad, which has limited vibration reduction effect. Especially in complex flight environments, they are difficult to effectively absorb high-frequency vibrations and impacts.

[0005] Therefore, designing a remote sensing image data acquisition device that combines efficient vibration reduction and intelligent heat dissipation has become an urgent technical challenge. Utility Model Content

[0006] This invention addresses the problems of vibration affecting image quality and heat accumulation leading to performance degradation when using remote sensing image data acquisition devices mounted on UAVs in existing technologies. It proposes a remote sensing image data acquisition device that improves stability and heat dissipation performance through optimized structural design. The device includes a base, an adjustable buffer structure, a connecting plate, a heat dissipation structure, and a connecting seat, and its specific implementation is as follows.

[0007] This invention provides a data acquisition device for remote sensing images, which solves the aforementioned technical problems through the synergistic effect of multiple functional modules. The base serves as the fundamental support for the entire device, and its surface is equipped with a mounting bracket for connecting to a drone. The mounting bracket is made of high-strength material and is fixed to the drone using a screw-locking method to ensure a stable connection between the device and the drone, thereby improving the overall structural stability.

[0008] Furthermore, the lower end of the base is connected to the connecting plate via an adjustable buffer structure. This adjustable buffer structure includes components such as a support cylinder, a spring, damping silicone, a screw, and a pressure plate. The support cylinder is fixed to the lower end of the base and has a connecting rod inserted inside. The connecting rod is connected to the connecting plate, forming a rigid connection while allowing for a certain degree of displacement compensation. A spring is sleeved on the outer wall of the support cylinder, with both ends of the spring abutting against the base and the connecting plate respectively. When subjected to external vibration, the spring absorbs and disperses the impact energy through elastic deformation, thus providing a buffering effect. The support cylinder is filled with damping silicone, whose high viscosity further enhances its properties. The system enhances the absorption capacity of high-frequency vibrations, thereby reducing the impact of vibrations on the imaging device. A nut is fixed to the upper end of the base, and a screw is screwed into the nut. The lower end of the screw passes through the base and the support cylinder and is rotatably connected to a pressure plate. The pressure plate is located inside the support cylinder and covers the damping silicone. By rotating the handle mounted on the upper end of the screw, the position of the pressure plate can be adjusted, thereby changing the degree of compression of the damping silicone and achieving flexible adjustment of the buffering effect. This design allows the buffer structure to be adaptively configured according to different flight environments and vibration intensities, thereby significantly improving the vibration resistance of the device.

[0009] Preferably, the connecting plate is located below the base and is connected to the base through an adjustable buffer structure. A connecting seat for connecting the imaging device is installed at its lower end. The connecting seat securely installs the imaging device on the connecting plate by screwing, preventing the imaging device from becoming loose due to vibration or external force. At the same time, shock-absorbing pads are embedded inside the connecting seat to further reduce the possibility of vibration being transmitted to the imaging device, thereby ensuring the stability of image acquisition.

[0010] Preferably, a heat dissipation structure is installed on one side of the lower end of the connecting plate. The heat dissipation structure includes components such as a support frame, a sliding groove, a slider, a fan, a motor, and studs. The support frame is fixed to one side of the lower end of the connecting plate, and sliding grooves are symmetrically opened on both sides. A slider is slidably arranged in the sliding groove, and a fan is connected to the slider through a bracket for heat dissipation of the imaging device. A motor is fixedly installed at the lower end of the support frame, and the motor shaft passes through the support frame and is fixedly connected to the stud. The stud is screwed to the slider. The motor drives the stud to rotate, which drives the slider and the fan to move along the sliding groove, realizing flexible adjustment of the heat dissipation position. This design allows the fan to dynamically adjust its position according to the actual working state and heat distribution of the imaging device, thereby completing the heat dissipation task more efficiently. The motor is a servo motor, which can be turned forward and reversed as needed.

[0011] Preferably, the fan in the heat dissipation structure adopts a centrifugal design with optimized blade angle, which can provide higher air volume output at a lower noise level. At the same time, the air inlet and outlet of the fan are equipped with guide shrouds to guide the airflow direction and reduce turbulence loss, thereby improving heat dissipation efficiency. In addition, the inner wall of the slide is coated with a low friction coefficient coating to reduce the resistance during the movement of the slider and ensure the stability and accuracy of the heat dissipation position adjustment.

[0012] The technical solution of this utility model achieves significant technical effects through innovative design of the buffer structure and heat dissipation structure. First, by using a combination of springs and damping silicone, the buffer structure effectively absorbs and disperses the vibrations generated during the drone's flight, reducing the impact of vibrations on the imaging device and improving the stability and clarity of image acquisition. Second, by using a motor to drive a fan to move along a slide, the heat dissipation structure can adjust its heat dissipation position as needed, effectively reducing the heat generated by the imaging device during operation and extending its service life. Finally, the overall structure is compact and reasonable, facilitating integration with drones and making it suitable for various remote sensing data acquisition scenarios.

[0013] In summary, this utility model significantly improves the performance of the remote sensing image data acquisition device by optimizing the buffer and heat dissipation structure design. The specific implementation of these innovations is as follows: S1, a buffer system is constructed by combining a support cylinder, a spring, and damping silicone; S2, the compression degree of the damping silicone is adjusted by using a screw and a pressure plate to achieve flexible adjustment of the buffering effect; S3, the screw is driven to rotate by a motor, which in turn drives the slider and fan to move along the slide groove to achieve dynamic adjustment of the heat dissipation position. The above technical solution not only solves the problems existing in the prior art, but also has high practical value and promising prospects for promotion. Attached Figure Description

[0016] This invention provides a data acquisition device for remote sensing images, which significantly improves the stability and heat dissipation performance of the imaging device through optimized buffer and heat dissipation structure design. The specific embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the overall structure of this utility model includes a base 1, an adjustable buffer structure 3, a connecting plate 4, a heat dissipation structure 5, and a connecting seat 6. The base 1 serves as the basic support part of the entire device, and a mounting seat 2 is provided on its upper surface. The mounting seat 2 is made of high-strength aluminum alloy material and is connected to the screw at the lower end of the UAV by a screw connection to ensure that the device remains stable during flight. The lower end of the base 1 is connected to the connecting plate 4 through the adjustable buffer structure 3. A heat dissipation structure 5 is installed on one side of the lower end of the connecting plate 4, and a connecting seat 6 for fixing the imaging device is installed on the other side.

[0018] like Figure 2 and Figure 3 As shown, the adjustable buffer structure 3 consists of a support cylinder 31, a spring 32, damping silicone 34, a pressure plate 35, a screw 37, and a throttle 38. The support cylinder 31 is fixed to the lower end of the base 1, and a connecting rod 33 is inserted inside it. The lower end of the connecting rod 33 is fixed to the connecting plate 4. The spring 32 is sleeved on the outer wall of the support cylinder 31, and the two ends of the spring 32 abut against the base 1 and the connecting plate 4, respectively. When the UAV vibrates during flight, the spring 32 absorbs and disperses the impact energy through elastic deformation, thus playing a preliminary buffering role. The support cylinder 31 is filled with damping silicone 34. The damping silicone 34 has high viscosity characteristics and can effectively absorb high-frequency vibrations, further reducing the impact of vibrations on the imaging equipment. Due to the influence of the position, a nut 36 is fixed to the upper end of the base 1, and a screw 37 is screwed into the nut 36. The lower end of the screw 37 passes through the base 1 and the support cylinder 31 and is connected to the pressure plate 35. The pressure plate 35 is located inside the support cylinder 31 and covers the damping silicone 34. By rotating the handle 38 mounted on the upper end of the screw 37, the position of the pressure plate 35 can be adjusted, thereby changing the degree of compression of the damping silicone 34. In specific operation, when it is necessary to enhance the buffering effect, rotate the handle 38 clockwise to move the pressure plate 35 downward and increase the compression of the damping silicone 34; conversely, rotate the handle 38 counterclockwise to reduce the compression of the damping silicone 34, thereby achieving flexible adjustment of the buffering effect.

[0019] like Figure 4 and Figure 5As shown, the heat dissipation structure 5 includes a support frame 51, a sliding groove 52, a slider 53, a fan 55, a motor 56, and a stud 57. The support frame 51 is fixed to one side of the lower end of the connecting plate 4, and sliding grooves 52 are symmetrically opened on both sides. The slider 53 is slidably arranged in the sliding grooves 52. The slider 53 is connected to the fan 55 through a bracket 54. The motor 56 is fixedly mounted on the lower end of the support frame 51. The shaft of the motor 56 passes through the support frame 51 and is fixedly connected to the stud 57. The stud 57 is screwed to the slider 53. The motor 56 drives the stud 57 to rotate, which drives the slider 53 to move along the sliding groove 52, thereby adjusting the position of the fan 55. This design allows the fan 55 to dynamically adjust its position according to the actual working state and heat distribution of the imaging device, thereby completing the heat dissipation task more efficiently. The fan 55 adopts a centrifugal design with optimized blade angles, which can provide higher air volume output at a lower noise level. Both the air inlet and outlet of the fan 55 are equipped with guide shields. The design of the guide shields guides the airflow direction and reduces turbulence loss, further improving heat dissipation efficiency. The inner wall of the slide 52 is coated with a low-friction coefficient coating to reduce the resistance during the movement of the slider 53 and ensure the stability and accuracy of the heat dissipation position adjustment.

[0020] like Figure 2 and Figure 5 As shown, the connecting plate 4 is connected to the imaging device via the connecting seat 6. The connecting seat 6 securely mounts the imaging device onto the connecting plate 4 using a screw connection, preventing the imaging device from loosening due to vibration or external force. The connecting seat 6 has embedded shock-absorbing pads made of high-molecular polymer material, which have good elasticity and shock absorption performance, further reducing the possibility of vibration being transmitted to the imaging device. The lower surface of the connecting seat 6 may be provided with heat dissipation fins, which correspond to the airflow direction of the fan 55 to improve the heat dissipation effect. The heat generated during the operation of the imaging device is conducted to the outside through the heat dissipation fins and then carried away by the airflow of the fan 55, thereby achieving efficient heat management.

[0021] The technical solution of this utility model has performed excellently in practical applications. When UAVs perform high-altitude remote sensing missions, they are easily affected by airflow disturbances due to the complex flight environment. At this time, the adjustable buffer structure 3 effectively absorbs and disperses vibrations through the synergistic effect of the spring 32 and the damping silicone 34, ensuring the stability of the imaging device. At the same time, the heat dissipation structure 5 dynamically adjusts the position of the fan 55 according to the working status of the imaging device to quickly dissipate heat and avoid the degradation of equipment performance due to overheating. Actual tests show that the imaging quality of the device of this utility model remains stable under long-term continuous working conditions, and the equipment temperature is always controlled within a safe range.

[0022] This invention significantly improves the performance of remote sensing image data acquisition devices by optimizing the design of buffer and heat dissipation structures. The buffer structure is a buffer system composed of a combination of a support cylinder 31, a spring 32, and a damping silicone rubber 34. The compression degree of the damping silicone rubber 34 can be adjusted by the screw 37 and the pressure plate 35 to achieve flexible adjustment of the buffering effect. The heat dissipation structure is driven by a motor 56 to rotate a stud 57, which in turn drives a slider 53 and a fan 55 to move along a groove 52 to achieve dynamic adjustment of the heat dissipation position.
