Description

Technical Field

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

[0002] Conducting field reconnaissance using hyperspectral survey instruments to enrich the spectral database of ground features is an important foundational task for quantitative inversion of ground features using aerospace hyperspectral or multispectral remote sensing. Currently, most geological surveys are conducted using UAVs equipped with hyperspectral survey instruments.

[0003] For example, in the existing technology of a remote sensing geological survey device, with the publication number CN220948602U, when the UAV finishes its remote sensing survey and lands on the ground, the elastic feet installed at the bottom of the UAV's outriggers first contact the ground. The springs inside the elastic outriggers provide cushioning protection for the device. When the UAV encounters an emergency situation (such as running out of power or malfunction) while conducting remote sensing surveys on the water surface and needs to make an emergency landing on the water surface, the floats installed on the UAV's outriggers can increase the buoyancy of the device, allowing it to float on the water surface and preventing the UAV body and the hyperspectral survey instrument from being submerged and damaged, thus better protecting the safety of the device.

[0004] However, in this device, the float is always fixed vertically to the drone's legs, which causes the drone to experience greater drag during flight. This results in a significant increase in the drone's flight energy consumption and a drastic reduction in its range. Furthermore, the greater drag also affects the drone's flight stability and maneuverability. When encountering airflow disturbances, the drone is more likely to deviate from its intended flight path, causing deviations in the data collected by the hyperspectral survey instrument and reducing work efficiency.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figure 1-6 As shown, a remote sensing geological survey device includes a UAV body 1 and a floating plate 4. Four support columns 19 are fixedly connected to the bottom of the UAV body 1. An extension plate 3 is fixedly connected to the bottom of the support columns 19. An installation column 5 is fixedly connected to the bottom of the extension plate 3. An installation disk 6 is fixedly connected to the middle of the installation column 5. The side of the installation disk 6 is hinged to the floating plate 4. The floating plate 4 is provided in two layers. Each layer of the floating plate 4 is provided with several floating plates arranged in a circular array around the axis of the installation disk 6. A transmission rod 12 is hinged to the opposite side of the two layers of floating plates 4. Two lifting sleeves 16 are symmetrically distributed around the installation disk 6 and sleeved on the outside of the installation column 5. The other end of the upper transmission rod 12 is hinged to the upper lifting sleeve 16, and the other end of the lower transmission rod 12 is hinged to the lower lifting sleeve 16.

[0027] In this technical solution, by setting an extension plate 3, the distance between the floats 4 on different mounting columns 5 is increased, the center is lowered, and the stability of the device is improved. By setting two layers of floats 4, the buoyancy is increased. By setting the floats 4 to be hinged to the mounting plate 6, when the two lifting sleeves 16 move towards the two ends of the mounting column 5 respectively, they drive the transmission rod 12 to move. The transmission rod 12 drives the floats 4 to rotate around the hinge point of the mounting plate 6, so that the floats 4 gradually approach the main body 1 of the UAV, complete the take-up action, and reduce the air resistance during flight.

[0028] like Figure 4 As shown, the mounting column 5 has a central cavity 15 inside, and a bidirectional threaded rod 11 is rotatably connected inside the central cavity 15. Two threaded sleeves 13 corresponding to the lifting sleeve 16 are slidably connected inside the central cavity 15. Both threaded sleeves 13 are threadedly engaged with the bidirectional threaded rod 11. The four support columns 19 are all fitted with pulley sets 9 for synchronously driving the four bidirectional threaded rods 11 to rotate. Two through grooves 7 are opened on the side of the mounting column 5, which are symmetrically distributed around the middle of the mounting column 5. The through grooves 7 extend along the axial direction of the mounting column 5. The threaded sleeves 13 are fixedly connected to the lifting sleeve 16 through the through grooves 7.

[0029] In this technical solution, the central cavity 15 provides installation space for the bidirectional threaded rod 11 and the threaded sleeve 13. When the bidirectional threaded rod 11 rotates, it drives the two threaded sleeves 13 to move relative to each other along the axial direction of the bidirectional threaded rod 11. By setting a pulley group 9, the rotation state of each bidirectional threaded rod 11 is kept consistent, so that the movement of the floats 4 connected to each mounting column 5 is kept synchronized. By setting a through groove 7, a channel is provided for the connection between the threaded sleeve 13 and the lifting sleeve 16. The threaded sleeve 13 is fixedly connected to the lifting sleeve 16 through the through groove 7, so that the movement of the threaded sleeve 13 in the central cavity 15 can be transmitted to the lifting sleeve 16. Then, the lifting sleeve 16 drives the transmission rod 12 to realize the control of the deployment and retraction of the floats 4, ensuring the stable operation of the entire remote sensing geological exploration device in different working scenarios.

[0030] like Figure 3 As shown, the top of the bidirectional threaded rod 11 extends outward through the mounting column 5 and the outer plate 3 and extends above the outer plate 3. The through end of the bidirectional threaded rod 11 is fixedly connected to a pulley 8. Each pulley 8 is connected to the pulley group 9 on the adjacent support column 19 through a belt strip. The four pulley groups 9 are connected in series through multiple belt strips to form a closed-loop transmission structure.

[0031] In this technical solution, when one of the pulley groups 9 rotates, it drives the pulley group 9 on the adjacent support column 19 to rotate via the belt strip. The belt strip then drives the pulley 8 adjacent to the support column 19 to rotate, which in turn drives the bidirectional threaded rod 11 to rotate. This cycle repeats, and the power is transmitted sequentially in the closed-loop structure, so that the four bidirectional threaded rods 11 rotate synchronously. The pulley group 9 is composed of three pulleys fixed to each other. In two adjacent pulley groups 9, a pair of pulleys of equal height are driven by a belt strip, which in turn drives the two adjacent pulley groups 9. In the pulley group 9 with the pulley 8 in a close position, the pulley 8 and a pulley of equal height in the pulley group 9 are driven by a belt strip.

[0032] like Figure 6 As shown, a mounting groove 2 is provided at the bottom of the main body 1 of the drone and around one of the support columns 19. A motor 10 is fixedly connected in the mounting groove 2. A gear 17 is fixedly connected to the main shaft of the motor 10. A toothed ring 14 that meshes with the gear 17 is sleeved on the outside of one of the support columns 19. The toothed ring 14 is coaxially fixed with the pulley group 9 on one of the support columns 19.

[0033] In this technical solution, by setting the mounting slot 2, a mounting position is provided for the motor 10. The motor 10 serves as a power source. After starting, its main shaft drives the gear 17 to rotate, which in turn drives the gear ring 14 to rotate. When the gear ring 14 rotates, it will drive the pulley group 9 to rotate synchronously.

[0034] like Figure 4 As shown, multiple limiting plates 18 are fixedly connected to the sides of the two lifting sleeves 16 and to the positions corresponding to the transmission rod 12. The upper limiting plate 18 is used to abut against the top of the transmission rod 12, and the lower limiting plate 18 is used to abut against the bottom of the transmission rod 12.

[0035] In this technical solution, when the float 4 is unfolded, the lifting sleeve 16 moves toward the mounting plate 6. When the float 4 is moved to a horizontal position, the transmission rod 12 also moves to a horizontal position. The limiting plate 18 and the mounting plate 6 clamp the transmission rod 12, keeping the transmission rod 12 fixed, thereby limiting the position of the float 4.

[0036] Working principle: During normal flight, the lifting sleeve 16 moves away from the mounting plate 6, driving the transmission rod 12 to keep the float 4 in a retracted state to reduce air resistance. When the UAV encounters an emergency situation during water surface survey and needs to make an emergency landing, the motor 10 rotates, driving one of the pulley groups 9 to rotate through the gear 17 and gear ring 14. This drives all the pulley groups 9 and pulleys 8 to rotate through the belt, which in turn drives the bidirectional threaded rod 11 to rotate, causing the lifting sleeve 16 to move towards the mounting plate 6. The lifting sleeve 16 pushes the transmission rod 12, which drives the float 4 to rotate around the hinge point of the mounting plate 6 until the float 4 unfolds to a horizontal position. At this time, the limiting plate 18 and the mounting plate 6 clamp the transmission rod 12, fixing the position of the float 4. The two layers of float 4 increase buoyancy, allowing the device to float on the water surface and preventing the UAV body 1 and the hyperspectral survey instrument from being damaged by water immersion.

[0037] The wiring diagram of the motor 10 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 10 will not be explained in detail.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
