Description

Technical Field

[0001] This utility model relates to the field of rock and mineral exploration technology, specifically a rock and mineral hyperspectral remote sensing device. Background Technology

[0002] Hyperspectral remote sensing is a cutting-edge field of remote sensing technology. It uses many narrow electromagnetic wave bands to obtain data from objects of interest. It contains rich spatial, radiometric, and spectral information. The emergence of hyperspectral remote sensing is a revolution in the field of remote sensing. It enables substances that were previously undetectable in broadband remote sensing to be identified through spectral data processing, image stitching, and spectral data interpretation, forming a complete set of core hyperspectral data. This allows for the identification of alteration minerals at different depths and their relative abundance in boreholes, and explores the effectiveness of core spectral alteration mineral methods.

[0003] A hyperspectral remote sensing geological survey device, disclosed in publication number CN 216269912 U, comprises an unmanned aerial vehicle (UAV) body with propellers mounted around its perimeter. A ground object spectrometer is mounted at the bottom of the UAV body, secured to the UAV body via bolts. This device utilizes internal support columns with supporting springs and buffer columns. Upon contact with the ground, the buffer columns compress the supporting springs, cushioning the device's descent. Four sets of push rods are mounted around the positioning components, and four sets of support rods are mounted around the connecting components. These allow the support rods to gradually unfold the push rods as the buffer columns retract, ensuring stability upon landing and resolving the issue of damage to the ground object spectrometer caused by descent pressure.

[0004] However, the above-mentioned devices still have some shortcomings in use. The outdoor environment has a large amount of dust and frequent rain. The existing devices lack an effective protective structure for ground object spectrometers. Dust can easily block the optical path of the spectrometer, and rainwater can easily seep in and damage the internal circuitry, directly affecting the accuracy of spectral data acquisition and the service life of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hyperspectral remote sensing device for rocks and minerals. It solves the problems of high dust levels and frequent rainfall in the field environment, the lack of effective protective structures for ground object spectrometers in existing devices, the easy clogging of spectrometer optical paths by dust, and the easy infiltration of rainwater that damages internal circuits, directly affecting the accuracy of spectral data acquisition and the service life of the device.

[0006] This utility model provides the following technical solution: a rock and mineral hyperspectral remote sensing device, including an unmanned aerial vehicle (UAV) body, an installation plate fixedly mounted on the lower end of the UAV body, two supports fixedly connected to the lower surface of the installation plate, a ground object spectrometer arranged between the two supports, a protective cover arranged below the installation plate, and the ground object spectrometer located inside the protective cover;

[0007] Both sides of the protective cover are fixedly connected to fixing plates. The lower surface of the mounting plate is fixedly connected to two short plates. The surfaces of the two short plates are provided with threaded holes. The interior of the two threaded holes is threaded with screws. One end of the two screws is rotatably mounted with a connecting plate.

[0008] Preferred technical solution 1: Multiple locking rods are fixedly connected to the surfaces of both connecting plates, and multiple locking grooves matching the locking rods are opened on the surfaces of both fixing plates.

[0009] Preferred technical solution 2: A set of limiting holes is provided on the surface of each of the two short plates, and a limiting rod is slidably sleeved inside each of the limiting holes. The two sets of limiting rods are fixedly connected to the two connecting plates respectively.

[0010] Preferred technical solution three: A horizontal plate is fixedly connected to both sides of the protective cover, and a set of positioning rods is fixedly connected to the upper surface of each of the two horizontal plates. The surface of the mounting plate is provided with two sets of positioning grooves that match the positioning rods.

[0011] Preferred technical solution four: an operating disc is fixedly connected to one end of each of the two screws, and a limiting disc is fixedly connected to one end of each limiting rod.

[0012] Preferred technical solution five: The main light-transmitting part of the protective cover is made of quartz glass, the non-light-transmitting support part of the protective cover is made of ABS engineering plastic and carbon fiber reinforcement layer, and the outer surface of the protective cover is coated with polytetrafluoroethylene coating.

[0013] Compared with the prior art, this utility model provides a hyperspectral remote sensing device for rocks and minerals, which has the following beneficial effects: During assembly, the positioning rods on both sides of the protective cover are first inserted into the two sets of positioning slots opened on the surface of the mounting plate to achieve the initial positioning of the protective cover and avoid subsequent installation misalignment; then, the operating disc at one end of the screw is rotated, which drives the screw to rotate in the threaded hole. As the screw rotates, the connecting plate will move towards the fixed plate fixedly connected to both sides of the protective cover until the locking rod is completely locked into the multiple locking slots opened on the surface of the fixed plate, completing the stable assembly of the protective cover and the mounting plate. At this time, the protective cover completely encloses the ground object spectrometer inside, and the quartz glass used in the light-transmitting part of the main body of the protective cover can ensure that there is no significant attenuation when the ground object spectrometer collects spectral signals. The non-light-transmitting support part uses ABS engineering plastic and carbon fiber reinforcement. The reinforced layer ensures structural strength, while the PTFE coating on the outer surface reduces dust adhesion. The drone then carries the entire device to the survey area. Under the protection of the protective cover, the ground-based spectrometer continuously captures the spectral signals reflected by the rocks and minerals below, transmitting the acquired spectral data to backend equipment for processing. This enables surveying tasks such as rock and mineral composition identification and distribution monitoring. To remove the protective cover for maintenance of the ground-based spectrometer, simply rotate the control panel in the reverse direction to disengage the locking lever from the slot, and then pull out the positioning rod to remove the protective cover. This rock and mineral hyperspectral remote sensing device features a protective cover that effectively protects against dust and rain without affecting spectral transmission. The cover can be quickly installed and removed, making it very convenient. The overall structure balances protection and operability, improving the reliability and lifespan of the device during field operations. Attached Figure Description

[0018] Please see Figure 1-3 ,

[0019] Example 1: A rock and mineral hyperspectral remote sensing device includes an unmanned aerial vehicle (UAV) body 1, with a mounting plate 2 fixedly mounted on the lower end of the UAV body 1. Two supports 3 are fixedly connected to the lower surface of the mounting plate 2, and a ground object spectrometer 4 is arranged between the two supports 3. A protective cover 5 is arranged below the mounting plate 2, and the ground object spectrometer 4 is located inside the protective cover 5.

[0020] Both sides of the protective cover 5 are fixedly connected to the fixing plate 6. The lower surface of the mounting plate 2 is fixedly connected to two short plates 7. The surfaces of the two short plates 7 are provided with threaded holes 8. The interiors of the two threaded holes 8 are threaded with screws 9. One end of the two screws 9 is rotatably installed with a connecting plate 10.

[0021] Example 2: The difference between this example and Example 1 is that multiple locking rods 11 are fixedly connected to the surfaces of both connecting plates 10, and multiple locking grooves 12 matching the locking rods 11 are opened on the surfaces of both fixing plates 6.

[0022] Example 3: The difference between this example and Example 1 is that each of the two short plates 7 has a set of limiting holes 13 on its surface, and each limiting hole 13 has a limiting rod 14 slidably fitted inside it. The two sets of limiting rods 14 are fixedly connected to the two connecting plates 10 respectively.

[0023] Example 4: The difference between this example and Example 1 is that, in this example, both sides of the protective cover 5 are fixedly connected with horizontal plates 15, and a set of positioning rods 16 are fixedly connected to the upper surface of the two horizontal plates 15. The surface of the mounting plate 2 is provided with two sets of positioning grooves 17 that match the positioning rods 16.

[0024] Example 5: The difference between this example and Example 1 is that, in this example, one end of each of the two screws 9 is fixedly connected to an operating disc 18, and one end of each limiting rod 14 is fixedly connected to a limiting disc 19.

[0025] Example 6: The difference between this example and Example 1 is that the main light-transmitting part of the protective cover 5 is made of quartz glass, the non-light-transmitting support part of the protective cover 5 is made of ABS engineering plastic and carbon fiber reinforcement layer, and the outer surface of the protective cover 5 is coated with polytetrafluoroethylene.

[0026] In summary, during assembly of this rock and mineral hyperspectral remote sensing device, the positioning rods 16 on both sides of the protective cover 5 are first aligned with the two sets of positioning slots 17 on the surface of the mounting plate 2 to achieve initial positioning of the protective cover 5 and prevent subsequent installation misalignment. Next, the operating disc 18 at one end of the screw 9 is rotated, causing the screw 9 to rotate within the threaded hole 8. As the screw 9 rotates, the connecting plate 10 moves towards the fixing plates 6 fixedly connected to both sides of the protective cover 5 until the locking rod 11 is fully engaged in the multiple locking slots 12 on the surface of the fixing plate 6, completing the stable assembly of the protective cover 5 and the mounting plate 2. At this point, the protective cover 5 completely encloses the ground object spectrometer 4. Furthermore, the quartz glass used in the light-transmitting part of the main body of the protective cover 5 ensures that there is no significant attenuation when the ground object spectrometer 4 collects spectral signals. The ABS engineering plastic and carbon fiber reinforcement layer used in the non-light-transmitting support part ensure... The structure is strong, and the polytetrafluoroethylene coating on the outer surface reduces dust adhesion. Then, the drone body 1 is activated, carrying the entire device to the survey area. Under the protection of the protective cover 5, the ground object spectrometer 4 continuously captures the spectral signals reflected by the rocks and minerals below, transmitting the acquired spectral data to the backend equipment for processing. This enables surveying work such as rock and mineral composition identification and distribution monitoring. If the protective cover 5 needs to be removed for maintenance of the ground object spectrometer 4, simply rotate the operating panel 18 in the reverse direction to disengage the locking rod 11 from the locking slot 12, and then pull out the positioning rod 16 to remove the protective cover 5. This rock and mineral hyperspectral remote sensing device features a protective cover that effectively prevents dust and rain without affecting spectral transmission. The protective cover 5 can be quickly installed and removed, making it very convenient. The overall structure balances protection and operability, improving the reliability and service life of the device in field operations.
