Description

Technical Field

[0001] The present invention relates to the technical field of hyperspectral measuring instruments, and in particular to a hyperspectral remote sensing measuring instrument that is convenient for installation and carrying on aircraft. Background Art

[0002] The hyperspectral remote sensing instrument is a remote sensing device designed specifically for aviation platforms (especially drones). Combining hyperspectral imaging technology with a lightweight, modular structure, it can efficiently obtain continuous spectral information of ground objects and adapt to the installation and carrying requirements of aviation environments. The hyperspectral remote sensing instrument captures the spectral data of the target in multiple narrow electromagnetic wave bands to generate continuous spectral images, which are used in environmental monitoring, precision agriculture, ecological research and other fields.

[0003] However, in actual use, after the operation of the drone carrying the measuring instrument is completed, the drone needs to be docked and sorted out. Most drones will take off and land in the same location area. Some drones carrying the measuring instrument will land nearby due to insufficient power or environmental factors after operation. The surrounding environment is unclear during landing, and the basic situation of the landing position can only be observed through the drone's built-in camera. During the landing process, if the terrain is not flat enough, the center of gravity of the drone and the measuring instrument is concentrated at a high place, the drone may tilt or roll over, and there may be a lot of weeds or raised stone particles on the landing ground that may contact the measuring instrument. The above problems will cause certain damage and bumps to the measuring instrument, thereby affecting the normal use of the measuring instrument and subsequent measurement tasks. Therefore, this application provides a high-spectral remote sensing measuring instrument that is easy to install and carry on aircraft to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a hyperspectral remote sensing measuring instrument that is easy to install and carry on an aircraft to solve the problem that some existing drones carrying measuring instruments will land nearby due to insufficient power after operation. During the landing process, if the terrain is not flat enough, the center of gravity of the drone and the measuring instrument will be concentrated at a high place, and the drone will tilt or roll over. There will also be a lot of weeds or stone particles at the bottom of the measuring instrument that will come into contact with the measuring instrument. The above problems will cause certain damage and bumps to the measuring instrument, thereby affecting the normal use of the measuring instrument and subsequent measurement tasks.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A hyperspectral remote sensing measuring instrument that is convenient for installation and carrying on aircraft includes a drone body, a reinforcing plate fixedly connected to the bottom of the drone body, a placement rack installed at the bottom of the reinforcing plate, a hyperspectral remote sensing measuring instrument installed in the middle position of the bottom of the placement rack, a support frame installed at the bottom of the reinforcing plate; and an auxiliary protection component, which is used to protect the safety of the support frame during landing and is connected to the reinforcing plate.

[0007] Optionally, the auxiliary protection assembly includes a moving block attached to the bottom of the reinforcing plate, the side of the moving block is hinged with an electric telescopic rod, and the bottom of the reinforcing plate is fixedly connected to a limiting plate.

[0008] Optionally, an adaptor column is fixedly connected to the middle position of the outer wall of the support frame, a rubber ring is slidably connected to the middle position of the outer wall of the support frame, and an extension bracket is slidably connected to the middle position of the support frame.

[0009] Optionally, the extension bracket is fixedly connected to an elastic plate 2 near the bottom of the support bracket, a fixing ring is fixedly connected to the middle position of the outer wall of the support bracket, and a buffer plate is fixedly connected to the top of the extension bracket away from the side of the support bracket.

[0010] Optionally, the end of the placement rack is slidably connected to a guide column, an airbag is slidably connected to the outer wall of the guide column, the bottom of the guide column is fixedly connected to a force-bearing frame, and the outer wall of the force-bearing frame is fixedly connected to elastic plate 1.

[0011] Optionally, the end of the force-bearing frame away from the guide column is fixedly connected to a connecting column, a plurality of limiting rings are fixedly connected to the inner wall of the connecting column, a clamping groove is provided in the middle position of the limiting ring, a movable groove is provided in the middle position of the limiting ring, and a clamping block is clamped on the outer wall of the limiting ring.

[0012] Optionally, the top of the limit plate is attached to the outer wall of the electric telescopic rod, a drive shaft is provided inside the electric telescopic rod, a universal ball is provided on the drive shaft, and the universal ball is hinged to the inner wall of the side of the moving block.

[0013] Optionally, the shape of the adapter column is consistent with the shape of the middle position of the support frame, one end of the extension bracket is slidably connected to the outer wall of the middle position of the support frame, and the other end is away from the support frame, and a weakened portion is provided in the middle position of the extension bracket.

[0014] Optionally, the top of the elastic plate 2 is fixedly connected to the bottom of the extension bracket close to the support bracket, the bottom of the elastic plate 2 is fixedly connected to the top of the fixed ring, and there are several elastic plates 2, and the buffer plate is inclined, with the intermediate position close to the extension bracket being low and the middle position away from the extension bracket being high.

[0015] Optionally, an anti-falling ring is provided on the top of the guide column, the airbag is slidably connected to the outer wall of the guide column, the top end of the elastic plate 1 is fixedly connected to the bottom of the placement rack, and the bottom end of the elastic plate 1 is fixedly connected to the top of the force-bearing rack.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by using the auxiliary protection component, the protection of the hyperspectral remote sensing instrument by the drone body during landing can be ensured. When the drone body falls or there are protrusions on the ground, the size of the auxiliary protection component will block the bottom of the hyperspectral remote sensing instrument, so that no matter whether the drone body falls vertically or falls, it will first contact the auxiliary protection component. The auxiliary protection component can reduce the direct damage to the hyperspectral remote sensing instrument caused by falling and other protrusions, and reduce the situation of damage or bumping into the hyperspectral remote sensing instrument, thereby ensuring the normal use of the hyperspectral remote sensing instrument and subsequent measurement tasks.

[0018] By arranging a rubber ring, an extension bracket, an elastic plate 2, and a buffer plate in the auxiliary protection component, the position of the support frame can be changed by using remote sensing technology during flight and take-off and landing, so that the contact distance between the extension bracket and the hyperspectral remote sensing instrument is different, which is suitable for the status under different scenarios. On the one hand, it does not affect the normal take-off and landing of the drone body. On the other hand, it can also effectively protect the hyperspectral remote sensing instrument during the descent process, so that when the drone body lands on an uneven or bumpy ground, the hyperspectral remote sensing instrument can still be protected to the greatest extent, reducing the number of external wear and collisions of the hyperspectral remote sensing instrument.

[0019] By arranging the airbag, the force-bearing frame, the elastic plate 1 and the connecting column, the elastic plate 1 is further squeezed, thereby dispersing the upward thrust of the connecting column on the elastic plate 1, the force-bearing frame and the airbag. On the one hand, it can ensure that the installation time will not be increased due to the complex structure when the hyperspectral remote sensing measuring instrument is clamped and fixed. On the other hand, the main structure formed by the placement frame, the airbag, the force-bearing frame and the elastic plate 1 can enhance the firmness of the hyperspectral remote sensing measuring instrument against its own weight. At the same time, the above structure is simple and easy to produce, and the material is mostly plastic, which effectively controls the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 12 As shown, an embodiment of the present invention provides a hyperspectral remote sensing measuring instrument that is convenient for installation and carrying on an aircraft, including a drone body 1, a reinforcing plate 2 is fixedly connected to the bottom of the drone body 1, a placement frame 3 is installed at the bottom of the reinforcing plate 2, a hyperspectral remote sensing measuring instrument 4 is installed at the middle position of the bottom of the placement frame 3, and a support frame 5 is installed at the bottom of the reinforcing plate 2; an auxiliary protection component, the auxiliary protection component is used to protect the safety of the support frame 5 during landing, the auxiliary protection component is connected to the reinforcing plate 2, the drone body 1, the reinforcing plate 2 and the hyperspectral remote sensing measuring instrument 4 are existing structures, without further details, the placement frame 3 is made of plastic material, the bottom of its middle position is just snap-fitted with the top of the hyperspectral remote sensing measuring instrument 4, the support frame 5 is an existing structure, and its middle position is bent, so that it can be used without affecting the support. During operation, any rotation of the hyperspectral remote sensing measuring instrument 4 will not affect the progress of the measurement work, and its top is also processed, and a fixed point is rotatably installed at its upper middle position, so that the middle main body part of the support frame 5 can be rotated through the fixed point.

[0042] Specifically, after the basic assembly of the drone body 1, the assembled state of the drone body 1, the reinforcement plate 2, the placement frame 3 and the support frame 5 is shown. In the initial state, except that the hyperspectral remote sensing measuring instrument 4 is not fixed under the drone body 1, the rest of the structures can be fixed and disassembled by bolts, and some structures can also be quickly disassembled using barrel shafts. In addition to the drone body 1 itself, if there are structures on the remaining reinforcement plates 2, the placement frame 3 and the support frame 5 that require motor drive, their power sources are all supplied by the battery in the drone body 1. Since the hyperspectral remote sensing measuring instrument 4 is a modern device, it has internal A self-sufficient power supply system, and if an electric drive structure is required, remote sensing is provided to facilitate remote control of the UAV body 1 after takeoff. Before use, the top of the hyperspectral remote sensing measuring instrument 4 is clamped to the bottom of the middle position of the reinforcing plate 2, and then the remote control device of the UAV body 1 is controlled to take off the UAV body 1 for operation. After takeoff, the support frame 5 is expanded outward as a whole through remote sensing to ensure that the hyperspectral remote sensing measuring instrument 4 can be rotated 360° in the air without blocking the field of view. When the UAV body 1 lands, remote sensing is still used to reset the posture of the support frame 5 to ensure that it can be effectively supported on the ground during landing.

[0043] By using the auxiliary protection component, the protection of the UAV body 1 to the hyperspectral remote sensing measuring instrument 4 can be ensured during landing. When the drone body 1 falls or there are protrusions on the ground, the size of the auxiliary protection component will block the bottom of the hyperspectral remote sensing measuring instrument 4, so that no matter whether the drone body 1 falls vertically or falls, it will first contact the auxiliary protection component. The auxiliary protection component can reduce the direct damage to the hyperspectral remote sensing measuring instrument 4 caused by falling and other protrusions, and reduce the situation of damage or bumping into the hyperspectral remote sensing measuring instrument 4, thereby ensuring the normal use of the hyperspectral remote sensing measuring instrument 4 and subsequent measurement tasks.

[0044] like Figures 9 to 12As shown, the auxiliary protection assembly includes a moving block 501 attached to the bottom of the reinforcing plate 2, an electric telescopic rod 503 is hinged on the side of the moving block 501, the bottom of the reinforcing plate 2 is fixedly connected to a limit plate 502, an adapter column 504 is fixedly connected to the middle position of the outer wall of the support frame 5, a rubber ring 505 is slidably connected to the middle position of the outer wall of the support frame 5, an extension bracket 506 is slidably connected to the middle position of the support frame 5, and the extension bracket 506 is fixedly connected to the elastic plate 502 near the bottom of the support frame 5. 7. A fixing ring 508 is fixedly connected to the middle position of the outer wall of the support frame 5. A buffer plate 509 is fixedly connected to the top of the extension bracket 506 away from the side of the support frame 5. The top of the limit plate 502 is attached to the outer wall of the electric telescopic rod 503. A drive shaft is provided inside the electric telescopic rod 503. A universal ball is provided on the drive shaft. The universal ball is hinged to the inner wall of the side of the moving block 501. The shape of the adapter column 504 is consistent with the shape of the middle position of the support frame 5. One end of the extension bracket 506 is slidably connected to the support frame 5. On the outer wall of the middle position of the support frame 5, the other end is away from the support frame 5, and a weakened part is provided in the middle position of the extension bracket 506. The top of the second elastic plate 507 is fixedly connected to the bottom of the extension bracket 506 near the support frame 5, and the bottom of the second elastic plate 507 is fixedly connected to the top of the fixing ring 508. There are several second elastic plates 507. The buffer plate 509 is inclined, and the intermediate position close to the extension bracket 506 is low, and the middle position away from the extension bracket 506 is high. The electric telescopic rod 503 is mainly controlled by the power supply inside the drone body 1. During the fixing process, there will be a power cord to connect the electric telescopic rod 503 to the power supply inside the drone body 1, and the drone body 1 has its installed remote sensing structure. A universal ball is installed on the drive shaft of the electric telescopic rod 503. The universal ball is movably hinged to the side of the moving block 501, and the moving block 501 and the top of the support frame 5 are fixedly connected. Several slots are opened in the middle position of the extension bracket 506 for lightweight design.

[0045] With the above structure, after the hyperspectral remote sensing measuring instrument 4 is installed and fixed, the drone body 1 is about to be controlled to perform aerial measurement operations. In the initial state, the bottom of the support frame 5 is against the ground, and the left and right support frames 5 form a certain angle, which will make the extension bracket 506 bear the force to support the hyperspectral remote sensing measuring instrument 4. When not taking off, the support frame 5 will open the extension bracket 506 and ensure that the bottom of the hyperspectral remote sensing measuring instrument 4 is in contact with the top of the extension bracket 506. At this time, the buffer plate 509 can play a certain buffering role. When the drone body 1 shakes slightly, the buffering effect of the buffer plate 509 will not cause the hyperspectral remote sensing measuring instrument 4 to shift from the middle position of the top of the extension bracket 506 to other places, and the extension bracket 506 The contact with the hyperspectral remote sensing measuring instrument 4 can be reflected when the hyperspectral remote sensing measuring instrument 4 is installed. Since the extension bracket 506 slides on the outer wall of the support frame 5, the extension bracket 506 can be pushed up and down by hand in daily use. In order to reduce the flexibility of the automatic sliding of the extension bracket 506, the extension bracket 506 and the outer wall of the support frame 5 are clamped tightly. When the drone body 1 is shaken, the impact on the extension bracket 506 is small. Only when pressure is applied to the middle position of the extension bracket 506, the extension bracket 506 will be displaced downward, or the hand force intervenes to push the extension bracket 506 to the position of the support frame 5 to achieve the overall displacement of the extension bracket 506, and then the drone body 1 is controlled. The body 1 starts to take off. During takeoff, the flight state can be controlled while the driving shaft of the electric telescopic rod 503 is remotely controlled to drive outward. During driving, the thrust will be extended to the top of the support frame 5, and the fixed point of the support frame 5 will move outward in an arc after receiving the thrust from the top. The driving shaft of the electric telescopic rod 503 is installed with a universal ball hinged on the side of the moving block 501, so the arc motion trajectory of the support frame 5 will not affect the horizontal push of the electric telescopic rod 503. After pushing, the top of the support frame 5 will expand outward, and the middle and lower parts of the support frame 5 will move inward, so the extension bracket 506 will be squeezed from the middle and lower parts of the support frame 5. During the squeezing process, since the middle position of the extension bracket 506 is provided with a weakened part, the extension bracket 506 will be squeezed. The middle part of the bracket 506 is pushed up, and in the process of the support frame 5 squeezing the extension bracket 506, the extension bracket 506 will slide downward on the outer wall of the support frame 5 under the action of the squeezing force, and the sliding distance will cause the distance of the top of the middle position of the extension bracket 506 to decrease, so that the hyperspectral remote sensing measuring instrument 4 will not be lifted up, avoiding limiting the flexibility of the rotation operation of the hyperspectral remote sensing measuring instrument 4, and the maximum distance that the extension bracket 506 can drop close to the support frame 5 is to contact the top of the fixing ring 508, and in the process of flight, the driving shaft of the electric telescopic rod 503 will always be in the extended state, so that the middle and lower ends of the support frame 5 will always squeeze the extension bracket 506, so that the middle position of the extension bracket 506 will be pushed up.The distance that the end portion of the extension bracket 506 slides with the support frame 5 is greater than the distance that the middle portion of the extension bracket 506 is lifted, so the extension bracket 506 as a whole will still descend until the end portion of the extension bracket 506 contacts the top position of the fixing ring 508. After the aerial operation is completed, during the descent process, the electric telescopic rod 503 is remotely controlled to retract the driving column. At this time, the moving block 501 is no longer subjected to force to push the top of the support frame 5, so that the top of the support frame 5 also moves inward when the electric telescopic rod 503 is retracted, returning to its initial state, and the middle and lower ends of the support frame 5 no longer squeeze the extension bracket 506, and the extension bracket 506 is close to the end portion of the support frame 5. The second elastic plate 507 is fixedly provided at the bottom. When it is not squeezed, the second elastic plate 507 will reset, so that the extension bracket 506 will also be in the initial position under the joint action of the second elastic plate 507 and the support frame 5. And since there are four second elastic plates 507, the reset process may have a large reset impact force. In order to avoid damage and fatigue to the position of the extension bracket 506 at the end of the support frame 5 after repeated use, a rubber ring 505 is provided as a buffer. In this way, when the extension bracket 506 resets and slides upward, it will first contact the rubber ring 505, and then drive the rubber ring 505 to continue to hit the bottom of the adapter column 504, lowering the The top of the extension bracket 506 is reduced to the situation where the top of the extension bracket 506 directly contacts the bottom of the adapter column 504, and the degree of damage caused by the extension bracket 506 hitting the bottom of the adapter column 504 is also reduced. In order to further improve the stability of the drone body 1 to the hyperspectral remote sensing measuring instrument 4 during the landing process, a symmetrical buffer plate 509 is provided on the top of the extension bracket 506. After the hyperspectral remote sensing measuring instrument 4 contacts the extension bracket 506, it is equivalent to protecting the hyperspectral remote sensing measuring instrument 4 from the side, so that the hyperspectral remote sensing measuring instrument 4 does not rotate and avoids collision with other objects during the rotation. By providing rubber rings 505, The extension bracket 506, the second elastic plate 507, and the buffer plate 509 can utilize remote sensing technology to change the position of the support frame 5 during flight and takeoff and landing, thereby varying the contact distance between the extension bracket 506 and the hyperspectral remote sensing instrument 4. This adapts to different scenarios, not only without affecting the normal takeoff and landing of the drone body 1, but also effectively protecting the hyperspectral remote sensing instrument 4 during descent. This allows the drone body 1 to be fully protected when landing on uneven or bumpy ground, thereby reducing the frequency of external wear and tear on the hyperspectral remote sensing instrument 4.

[0046] like Figures 6 to 8The top of the guide post 301 is provided with an anti-falling ring, and the airbag 302 is slidably connected to the outer wall of the guide post 301. The bottom of the guide post 301 is fixedly connected to a force-bearing frame 303, and the outer wall of the force-bearing frame 303 is fixedly connected to an elastic plate 1 304. The end of the force-bearing frame 303 away from the guide post 301 is fixedly connected to a connecting post 305, and a plurality of limiting rings 306 are fixedly connected to the inner wall of the connecting post 305. A clamping groove 307 is provided in the middle position of the limiting ring 306, and a movable groove 308 is provided in the middle position of two adjacent limiting rings 306. A clamping block 309 is clamped on the outer wall of the limiting ring 306. An anti-falling ring is provided on the top of the guide post 301, and the airbag 302 is slidably connected to the outer wall of the guide post 301. The top of the elastic plate 1 304 is fixedly connected to the bottom of the placement frame 3, and the bottom end of the elastic plate 1 304 is fixedly connected to The top of the force-bearing frame 303 and the placement frame 3 are fixed to the bottom of the reinforcing plate 2 by bolts. The placement frame 303 and the force-bearing frame 303 are divided into four circumferential array parts by the connecting column 305. The top is fixed by bolts, and the bottom is connected to each other by the connecting column 305. When the connecting column 305 is pushed upward, the force-bearing frame 303 and the elastic plate 1 304 are driven. After the elastic plate 1 304 is compressed, the entire force-bearing frame 303 moves upward, so that the airbag 302 will be squeezed by the upward force-bearing frame 303, and the pressurized airbag 302 will also move upward along the guide column 301 while being compressed, so that the driving force of the airbag 302 is also transmitted to the placement frame 3, and the upward thrust is gradually dispersed. Through the above structure, the hyperspectral remote sensing measuring instrument 4 is taken out, and then the clamping block 309 is clamped or bolted to the top of the hyperspectral remote sensing measuring instrument 4, and then according to Figure 8The handheld hyperspectral remote sensing measuring instrument 4 is vertically clamped upward and entered into the connecting column 305. After rising to the top of the inner wall of the connecting column 305 and feeling that it can no longer rise, the clamping block 309 is no longer in contact with the movable groove 308. Then it is slowly lowered while rotating. During the rotation process, the protruding parts at both ends of the clamping block 309 are in contact with the clamping groove 307 and clamped. At this time, the hyperspectral remote sensing measuring instrument 4 is released, and under the action of gravity of the hyperspectral remote sensing measuring instrument 4, the clamping block 309 will be firmly It is firmly connected to the clamping groove 307 and cannot be rotated from the inside of the connecting column 305. The top of the hyperspectral remote sensing measuring instrument 4 can only be rotated by the rotation mechanism on the hyperspectral remote sensing measuring instrument 4. During the rotation, the clamping block 309 will be firmly connected to the clamping groove 307 and cannot be rotated. In the process of installing the hyperspectral remote sensing measuring instrument 4, it is also mentioned that the hyperspectral remote sensing measuring instrument 4 needs to be vertically inserted with the clamping block 309 into the top of the inner wall of the connecting column 305 to contact the top of the inner wall of the connecting column 305. After that, people will continue to move upward a short distance due to the action of inertial force. At this time, there is no space left on the inner wall of the connecting post 305 for upward movement, and the clamping block 309 will begin to squeeze the inner wall of the connecting post 305, causing the entire connecting post 305 to move upward. In addition, the end of the force-bearing frame 303 is fixed on the outer wall of the connecting post 305, so that the movement of the connecting post 305 will drive the force-bearing frame 303 to move upward near the end of the connecting post 305, further squeezing the elastic plate 1 304, thereby dispersing the upward thrust of the connecting post 305 on the elastic plate 1 304, the force-bearing frame 303 and the airbag 302. On the one hand, it can ensure that the installation time is not increased due to the complex structure when the hyperspectral remote sensing measuring instrument 4 is clamped and fixed. On the other hand, the main structure formed by the placement frame 3, the airbag 302, the force-bearing frame 303 and the elastic plate 1 304 can enhance the firmness of the hyperspectral remote sensing measuring instrument 4 against its own weight. At the same time, the above structure is simple and easy to produce, and the material is mostly plastic, which effectively controls the production cost.

[0047] The working principle of the technical solution provided by the present invention is as follows:

[0048] Specifically, after the basic assembly of the drone body 1, the assembled state of the drone body 1, the reinforcement plate 2, the placement frame 3 and the support frame 5 is shown. In the initial state, except that the hyperspectral remote sensing measuring instrument 4 is not fixed under the drone body 1, the rest of the structures can be fixed and disassembled by bolts, and some structures can also be quickly disassembled using barrel shafts. In addition to the drone body 1 itself, if there are structures on the remaining reinforcement plates 2, the placement frame 3 and the support frame 5 that require motor drive, their power sources are all supplied by the battery in the drone body 1. Since the hyperspectral remote sensing measuring instrument 4 is a modern device, it has internal A self-sufficient power supply system, and if an electric drive structure is required, remote sensing is provided to facilitate remote control of the UAV body 1 after takeoff. Before use, the top of the hyperspectral remote sensing measuring instrument 4 is clamped to the bottom of the middle position of the reinforcing plate 2, and then the remote control device of the UAV body 1 is controlled to take off the UAV body 1 for operation. After takeoff, the support frame 5 is expanded outward as a whole through remote sensing to ensure that the hyperspectral remote sensing measuring instrument 4 can be rotated 360° in the air without blocking the field of view. When the UAV body 1 lands, remote sensing is still used to reset the posture of the support frame 5 to ensure that it can be effectively supported on the ground during landing.

[0049] Take out the hyperspectral remote sensing measuring instrument 4, then clamp the clamping block 309 or fix it on the top of the hyperspectral remote sensing measuring instrument 4 with bolts, and then follow the steps below. Figure 8The handheld hyperspectral remote sensing measuring instrument 4 is vertically clamped upward and entered into the connecting column 305. After rising to the top of the inner wall of the connecting column 305 and feeling that it can no longer rise, the clamping block 309 is no longer in contact with the movable groove 308. Then it is slowly lowered while rotating. During the rotation process, the protruding parts at both ends of the clamping block 309 are in contact with the clamping groove 307 and clamped. At this time, the hyperspectral remote sensing measuring instrument 4 is released, and under the action of gravity of the hyperspectral remote sensing measuring instrument 4, the clamping block 309 will be firmly It is firmly connected to the clamping groove 307 and cannot be rotated from the inside of the connecting column 305. The top of the hyperspectral remote sensing measuring instrument 4 can only be rotated by the rotation mechanism on the hyperspectral remote sensing measuring instrument 4. During the rotation, the clamping block 309 will be firmly connected to the clamping groove 307 and cannot be rotated. In the process of installing the hyperspectral remote sensing measuring instrument 4, it is also mentioned that the hyperspectral remote sensing measuring instrument 4 needs to be vertically inserted with the clamping block 309 into the top of the inner wall of the connecting column 305 to contact the top of the inner wall of the connecting column 305. After that, people will continue to move upward a short distance due to the action of inertial force. At this time, there is no space left on the inner wall of the connecting post 305 for upward movement, and the clamping block 309 will begin to squeeze the inner wall of the connecting post 305, causing the entire connecting post 305 to move upward. In addition, the end of the force-bearing frame 303 is fixed on the outer wall of the connecting post 305, so that the movement of the connecting post 305 will drive the force-bearing frame 303 to move upward near the end of the connecting post 305, further squeezing the elastic plate 1 304, thereby dispersing the upward thrust of the connecting post 305 on the elastic plate 1 304, the force-bearing frame 303 and the airbag 302. On the one hand, it can ensure that the installation time is not increased due to the complex structure when the hyperspectral remote sensing measuring instrument 4 is clamped and fixed. On the other hand, the main structure formed by the placement frame 3, the airbag 302, the force-bearing frame 303 and the elastic plate 1 304 can enhance the firmness of the hyperspectral remote sensing measuring instrument 4 against its own weight. At the same time, the above structure is simple and easy to produce, and the material is mostly plastic, which effectively controls the production cost.

[0050] After the hyperspectral remote sensing measuring instrument 4 is installed and fixed, the drone body 1 is about to be controlled to perform aerial measurement operations. In the initial state, the bottom of the support frame 5 is against the ground, and the left and right support frames 5 form a certain angle, which will make the extension bracket 506 bear the force to support the hyperspectral remote sensing measuring instrument 4. When not taking off, the support frame 5 will open the extension bracket 506 and ensure that the bottom of the hyperspectral remote sensing measuring instrument 4 is in contact with the top of the extension bracket 506. At this time, the buffer plate 509 can play a certain buffering role. When the drone body 1 shakes slightly, the buffering effect of the buffer plate 509 will not cause the hyperspectral remote sensing measuring instrument 4 to shift from the middle position of the top of the extension bracket 506 to other places, and the extension bracket 506 and the hyperspectral remote sensing measuring instrument 4 will not be able to move. The contact can be reflected when the hyperspectral remote sensing measuring instrument 4 is installed. Since the extension bracket 506 slides on the outer wall of the support frame 5, the extension bracket 506 can be pushed up and down by hand in daily use. In order to reduce the flexibility of the automatic sliding of the extension bracket 506, the extension bracket 506 is clamped tightly with the outer wall of the support frame 5. When the drone body 1 is shaken, the impact on the extension bracket 506 is small. Only when pressure is applied to the middle position of the extension bracket 506 will the extension bracket 506 be displaced downward, or the hand force intervenes to push the extension bracket 506 to the position of the support frame 5 to achieve the overall displacement of the extension bracket 506, and then the drone body 1 is controlled to start taking off. During takeoff, The flight state can be controlled while the driving shaft of the electric telescopic rod 503 is driven outward by remote control. When driving, the thrust will be extended to the top of the support frame 5, and the fixed point of the support frame 5 will move outward in an arc shape after receiving the thrust from the top. The driving shaft of the electric telescopic rod 503 is installed with a universal ball hinged on the side of the moving block 501, so the arc motion trajectory of the support frame 5 will not affect the horizontal push of the electric telescopic rod 503. After pushing, the top of the support frame 5 will expand outward, and the middle and lower parts of the support frame 5 will move inward, and the extension bracket 506 will be squeezed from the middle and lower parts of the support frame 5. During the squeezing process, since the middle position of the extension bracket 506 is provided with a weakened part, the middle part of the extension bracket 506 will be pushed upward after squeezing, and When the support frame 5 squeezes the extension bracket 506, the extension bracket 506 will slide downward on the outer wall of the support frame 5 under the action of the squeezing force, and the sliding distance will cause the distance of the top of the middle position of the extension bracket 506 to decrease, so that the hyperspectral remote sensing measuring instrument 4 will not be lifted up, avoiding limiting the flexibility of the hyperspectral remote sensing measuring instrument 4 in rotating operation, and the maximum distance that the extension bracket 506 can drop close to the support frame 5 is to contact the top of the fixing ring 508, and during the flight, the driving shaft of the electric telescopic rod 503 will always be in the extended state, so that the middle and lower ends of the support frame 5 will always squeeze the extension bracket 506, so that the middle position of the extension bracket 506 will be lifted up, and the sliding end of the extension bracket 506 and the support frame 5,The distance of the downward movement is greater than the distance the middle part of the extension bracket 506 is lifted, so the extension bracket 506 as a whole will still fall until the end of the extension bracket 506 contacts the top position of the fixing ring 508. After the aerial operation is completed, during the descent process, the electric telescopic rod 503 is remotely controlled to retract the driving column. At this time, the moving block 501 is no longer forced to push the top of the support frame 5, so that the top of the support frame 5 also moves inward when the electric telescopic rod 503 is retracted, returning to the initial state, and the middle and lower ends of the support frame 5 no longer squeeze the extension bracket 506. The extension bracket 506 is close to the end of the support frame 5 and an elastic plate 507 is fixed below it. , after not being squeezed, the elastic plate 2 507 will reset, so that the extension bracket 506 will also be in the initial position under the joint action of the elastic plate 2 507 and the support frame 5, and since there are four elastic plates 2 507, the reset process may have a large reset impact force. In order to avoid damage and fatigue to the position of the extension bracket 506 at the end of the support frame 5 after repeated use, a rubber ring 505 is provided as a buffer. In this way, when the extension bracket 506 resets and slides upward, it will first contact the rubber ring 505, and then drive the rubber ring 505 to continue to impact the bottom of the adapter column 504, reducing the extension bracket 506. The top of the UAV directly contacts the bottom of the adapter column 504, which also reduces the damage caused by the extension bracket 506 hitting the bottom of the adapter column 504. In order to further improve the stability of the UAV body 1 on the hyperspectral remote sensing measuring instrument 4 during the landing process, a symmetrical buffer plate 509 is provided on the top of the extension bracket 506. After the hyperspectral remote sensing measuring instrument 4 contacts the extension bracket 506, it is equivalent to protecting the hyperspectral remote sensing measuring instrument 4 from the side, so that the hyperspectral remote sensing measuring instrument 4 will not rotate and will not collide with other objects during the rotation. By arranging rubber rings 505 and the extension bracket 506 in the auxiliary protection component, the extension bracket 506 can effectively prevent the hyperspectral remote sensing measuring instrument 4 from rotating. 06. The second elastic plate 507 and the buffer plate 509 can utilize remote sensing technology to change the position of the support frame 5 during flight and takeoff and landing, thereby varying the contact distance between the extension bracket 506 and the hyperspectral remote sensing instrument 4. This adapts to different scenarios. On the one hand, it does not affect the normal takeoff and landing of the drone body 1. On the other hand, it can also effectively protect the hyperspectral remote sensing instrument 4 during descent. When the drone body 1 lands on uneven or bumpy ground, it can still protect the hyperspectral remote sensing instrument 4 to the greatest extent, reducing the number of external wear and collisions on the hyperspectral remote sensing instrument 4.
