Description

Technical Field

[0001] The present invention relates to the technical field of aerial photography space planning, and in particular to an aerial photography measurement auxiliary device for national land space planning. Background Art

[0002] As we all know, aerial photography and measurement of national land space planning is an important technical means in the preparation and implementation of national land space planning. It uses professional surveying equipment on drones, manned aircraft and other aerial vehicles to conduct aerial photography and measurement of land, terrain, landforms, and objects in a specific area to obtain relevant geographic spatial information. It provides high-precision and current basic data for national land space planning, including land use status, natural resource distribution, ecological environment status, etc., to assist planners in making scientific and reasonable spatial layout and resource allocation.

[0003] When performing aerial photography space planning, it is necessary to use a measurement auxiliary device. The existing technology has the following problems: when using drones to assist in space planning measurement, multiple parameters are usually required, including but not limited to collecting physical features through image acquisition, measuring through infrared technology, and using multiple sensors to collect parameters such as air flow humidity in the surrounding environment. Therefore, more equipment needs to be mounted, and multiple measurements are required. Not only is the efficiency limited, but it is also difficult to ensure that the position of each measurement is consistent. If installed on a single drone, it is not only limited by the limited installation position of the drone, but also the distance between the collection devices is too close and they are easy to affect each other. The area of ​​multiple devices deployed at the same time is large, which will increase wind resistance during flight. The weight of the equipment is also different, so it is difficult to ensure that the equipment is balanced when installed at the bottom of the drone. Based on the above-mentioned situation, we found that it is difficult for the existing aerial photography and measurement auxiliary device for land and space planning to avoid the above problems at the same time. Therefore, we proposed an aerial photography and measurement auxiliary device for land and space planning that can mount a large number of devices, reduce wind resistance during flight, use multiple devices when hovering, and adjust the horizontal position of the equipment to maintain relative balance during the flight and hovering process, while reducing the impact of the drone's own movements on the collection equipment. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides an aerial photography and measurement auxiliary device for national land space planning, which can carry a large number of equipment, reduce wind resistance during flight, and use a variety of equipment when hovering. At the same time, the horizontal position of the equipment can be adjusted to maintain relative balance during the flight and hovering process, while reducing the impact of the drone's own movements on the collection equipment.

[0005] (II) Technical solution The above technical objectives of the present invention are achieved through the following technical solutions: an aerial photography measurement auxiliary device for land space planning, comprising an unmanned aerial vehicle main body, a sub-frame fixedly connected to the top of the unmanned aerial vehicle main body, a tilt frame fixedly connected to the outside of the unmanned aerial vehicle main body, a bottom frame fixedly connected to the front and rear sides of the bottom of the unmanned aerial vehicle main body, a suspension structure installed at the bottom of the unmanned aerial vehicle main body, an equipment frame fixedly connected to the bottom of the suspension structure, and two balancing frames installed at the bottom of the equipment frame; The balancing frame comprises an outer frame and an inner frame, wherein the inner frame is slidably connected to the inner side of the outer frame, the outer frame and the inner frame are both made of hollow metal profiles, the front and rear sides of the inner frame and the outer frame are both provided with horizontal grooves, the inner sides of the inner frame and the outer frame are both provided with hollow concave, and the inner side of the hollow concave is provided with a translation structure; The translation structure includes a U-shaped frame, the inner side of the U-shaped frame is rotatably connected with a driving shaft and a driven shaft, the outer sides of the driving shaft and the driven shaft are both installed with rollers, the outer sides of the rollers are fixedly connected with friction wheels, the outer side of the U-shaped frame is fixedly connected with a control motor, the output shaft of the control motor is fixedly connected to the driving shaft on one side close to the driving shaft, the outer sides of the driving shaft and the driven shaft are both fixedly connected with telescopic rods, the side of the telescopic rods close to the rollers is fixedly connected to the rollers, the outer sides of the driving shaft and the driven shaft are both fixedly connected with pressure springs, the side of the pressure springs close to the rollers is fixedly connected to the rollers, the pressure springs are sleeved on the outer side of the telescopic rods, and the bottom of the U-shaped frame is fixedly connected with an equipment plate; The suspension structure includes an upper connecting tube, a lower connecting tube and a narrow barrel section, the top of the inner side of the upper connecting tube and the bottom of the inner side of the lower connecting tube are fixedly connected with a rotating shaft, the side of the rotating shaft close to the narrow barrel section is rotatably connected to the narrow barrel section, a wide section is provided in the middle of the inner side of the narrow barrel section, the top of the inner wall of the wide section is fixedly connected with a connecting ball, the outer side of the connecting ball is slidably connected with a counterweight frame, the inner side of the wide section is filled with silicone oil, the top and bottom of the outer side of the narrow barrel section are fixedly connected with airbags, the outer sides of the two airbags are respectively fixedly connected to the upper connecting tube and the lower connecting tube, the top of the upper connecting tube is fixedly connected to the drone body, and the bottom of the lower connecting tube is fixedly connected to the top of the equipment rack.

[0006] By adopting the above technical scheme, the drone body is set as a carrier, and the internal components are installed through the sub-frame. The inclined frame is set to protect the fan blade position of the drone body to avoid injuries when people touch it. The suspension structure is used to connect the drone body and the equipment frame. The equipment frame is used to install the collection and detection equipment through the balance frame. The outer frame cooperates with the inner frame. The inner frame can be pulled out or retracted from the inside of the outer frame to adjust the occupied space when the equipment is installed or the position is adjusted. The translation structure connected by the hollow concave and the horizontal groove can be horizontally moved along the inside of the inner frame and the outer frame. Before use, the detection or collection equipment can be directly assembled with the equipment plate of the translation structure as needed. When the main body of the UAV is flying, the inner frame is retracted into the inner side of the outer frame to reduce the area of ​​the structure, which can reduce air resistance. At the same time, the center of gravity is concentrated as much as possible to be directly below the bottom of the main body of the UAV to maintain flight stability. When flying to the measurement and collection position, the main body of the UAV hovers. At this time, the inner frame can be controlled to be pulled out from the inner side of the outer frame to expand the working space. The translation structure connected to each device is controlled according to needs. The control motor is rotated forward or reverse. The active shaft connected to the output end drives the roller and the outer friction wheel to rotate through the telescopic rod. The friction wheel contacts the hollow inner concave inside the outer frame or the inner frame, and drives the entire U-shaped frame connected to it to move horizontally along the outer frame and the inner frame through friction, so as to start To achieve the effect of adjusting the position of the installed equipment, since the size of the inner frame is slightly smaller than that of the outer frame, there will be a small height difference when passing through the connection between the inner frame and the outer frame. When the friction wheel and the roller pass through this place, the driving shaft and the driven shaft are limited by the horizontal groove, so the vertical height is inconvenient. When moving to the hollow concave part inside the outer frame, the pressure spring is pressed, and the telescopic rod is forced to retract, so that the roller and the friction wheel rotate eccentrically relative to the driving shaft and the driven shaft, so as to achieve a normal transmission effect. Since the position of the equipment can be freely controlled to move, the distance between the equipment can be controlled to move away from each other when the distance between the equipment is too close. When the center of gravity is offset due to the concentrated position of the equipment between the outer frame and the inner frame on one side, the equipment installed outside the outer frame and the inner frame on the other side can be The suspension structure is set up to coordinate the center of gravity by horizontal movement. In addition to serving as the connection between the top structure and the bottom structure, even if the center of gravity of the bottom structure is inconsistent but difficult to adjust, the upper connecting tube, the lower connecting tube and the narrow tube section will rotate to a certain extent along the rotating shaft, and the airbag as a support can play a certain compensation effect, thereby increasing the allowable error of the structural position adjustment during detection and collection. Since the UAV itself will vibrate during continuous operation, the narrow tube section and the wide section as the connection position between the UAV and the bottom structure will also vibrate. At this time, the silicone oil will produce viscous resistance to the inner wall of the cavity. Because the internal friction between the silicone oil molecules is large, when the counterweight frame in the cavity moves along the connecting ball in the silicone oil, it needs to overcome this viscous resistance, which will consume the energy of the vibration.This has the effect of shock absorption. When the drone is subjected to high-frequency and small-amplitude vibrations, silicone oil can effectively suppress the transmission of vibrations, reducing the vibration impact on the data acquisition equipment of the bottom structure. Since multiple devices are allowed to operate at the same time, it can also ensure that the data detection and collection positions are close, reducing errors in measurement planning.

[0007] The present invention is further configured as follows: outer sides of the driving shaft and the driven shaft are in contact with the horizontal groove, and outer sides of the driving shaft and the driven shaft are fixedly connected with bonding sheets.

[0008] By adopting the above technical solution, the horizontal groove is provided to limit the displacement position of the driving shaft and the driven shaft, and the bonding sheet is used to ensure that they are not prone to tilting during horizontal movement.

[0009] The present invention is further configured as follows: the bottom of the U-shaped frame is slidably connected to a slide, the top of the slide is fixedly connected to a limiting frame, the inner side of the limiting frame is rotatably connected to a limiting wheel, the top of the limiting wheel is respectively used in conjunction with the outer frame and the inner frame, the bottom of the limiting frame is fixedly connected to a hard spring, the bottom of the hard spring is fixedly connected to the U-shaped frame, and the hard spring is sleeved on the outer side of the slide.

[0010] By adopting the above technical solution, the limit frame can be easily installed on the inner side of the U-shaped frame by setting a slide frame. The limit wheel on the inner side of the limit frame will always contact the bottom of the outer frame or the inner frame due to the pressure of the hard spring, thereby further limiting the structure and preventing it from loosening.

[0011] The present invention is further configured as follows: the equipment frame includes an empty cylinder, an electric cylinder is fixedly connected to the inner side of the empty cylinder, a movable frame is fixedly connected to the telescopic end of the electric cylinder, an outer side of the movable frame is rotatably connected to an external support, an outer side of the empty cylinder is rotatably connected to an inclined frame, and the inner side of the inclined frame is rotatably connected to the external support.

[0012] By adopting the above technical solution, an empty cylinder is arranged to cooperate with an electric cylinder. The electric cylinder is normally in an extended state. At this time, the movable frame and the external support will pull the inclined frame to rotate and tilt along the top of the empty cylinder to keep the bottoms of the inclined frame close to each other. Because the inclined frame is connected to the outer frame and the inner frame, most of the inner frame is located on the inner side of the outer frame at this time. When operation is required, the telescopic end of the electric cylinder retracts, which will drive the movable frame to move upward. At this time, the external support will push the inclined frame to rotate along the empty cylinder to open the structure. At this time, the inner frame is pulled out from the inner side of the outer frame to expand the moving position of the structure.

[0013] The present invention is further configured as follows: the number of the inclined frames is four, a connecting block is installed at the bottom of the inclined frame, the outer sides of the two connecting blocks on the left are rotatably connected to the two outer frames respectively, and the outer sides of the two connecting blocks on the right are rotatably connected to the two inner frames respectively.

[0014] By adopting the above technical solution, a connecting block is provided to reasonably connect the inclined frame and the inner frame or the outer frame, and at the same time, the structures can be reasonably rotated to facilitate the transmission of the structure and not easily get stuck.

[0015] The present invention is further configured as follows: an extension frame is slidably connected to the inner side of the base frame, a foot plate is fixedly connected to the bottom of the extension frame, and a buffer spring is sleeved on the outer side of the extension frame.

[0016] By adopting the above technical solution, an extension frame is set up to cooperate with a foot plate, and the foot plate is used to make the main body of the drone contact the ground when landing. Because it is long, it is not easy for the blades to get stuck in plants in the ground environment when landing on different terrains. Since the device may carry too many devices, its own weight is heavy. The buffer spring set during landing is deformed due to contact with the foot plate, thereby preventing the device from directly contacting the ground rigidly and causing damage to the equipment.

[0017] The present invention is further configured as follows: a photovoltaic panel is provided on the outer side of the tilting frame, a panel support is fixedly connected to a side of the photovoltaic panel close to the tilting frame, and the panel support is movably connected to the tilting frame.

[0018] By adopting the above technical solution, by setting up photovoltaic panels in conjunction with panel brackets, the photovoltaic panels can assist in photovoltaic auxiliary energy supply, and their controllers, batteries, inverters, etc. can be installed on the inside of the sub-frame or on the bottom of the drone body, and the panel brackets are used to install and fix the photovoltaic panels.

[0019] The present invention is further configured as follows: a clamping frame is fixedly connected to the outer side of the tilting frame, a buffer pad is fixedly connected to the inner side of the clamping frame, and the inner side of the buffer pad is fixedly connected to the board support.

[0020] The above technical solution is adopted, by setting a card frame and a buffer pad to connect the tilt frame and the panel bracket. At the same time, when the drone body may be hit, the photovoltaic panel directly contacts the force-bearing position to reduce the damage to the drone body. The buffer pad can play a certain buffering role when subjected to force.

[0021] The present invention is further configured as follows: two parallel frames are provided on the inner side of the panel support, and a protective net is fixedly connected between opposite sides of the two parallel frames.

[0022] By adopting the above technical solution, a parallel frame is set up in conjunction with a protective net. The protective net plays a certain protective role on the top of the UAV body. When operating in complex terrain, it can reduce the possibility of external impurities falling and getting entangled in the blades, causing structural damage or affecting normal operations.

[0023] The present invention is further configured as follows: a through hole is opened on the inner side of the panel support, a bolt is arranged on the inner side of the panel support, and a side of the bolt close to the through hole passes through the through hole and is threadedly connected to the parallel frame.

[0024] By adopting the above technical solution, the protective net can be easily disassembled together with the parallel frame by setting through holes and bolts. In locations with open terrain, the dead weight of the structure can be reduced by dismantling the structure, thereby improving the endurance to a certain extent.

[0025] (III) Beneficial effects Compared with the prior art, the present invention provides an aerial photography measurement auxiliary device for national land space planning, which has the following beneficial effects: The aerial photography and measurement auxiliary device for national land space planning sets a drone body as a carrier, and installs internal components through a sub-frame. The set tilt frame can protect the fan blade position of the drone body to avoid injuries when people touch it. The set suspension structure is used to connect the drone body and the equipment frame. The equipment frame is used to install the collection and detection equipment through a balance frame. The outer frame cooperates with the inner frame. The inner frame can be pulled out or retracted from the inner side of the outer frame to adjust the occupied space when the equipment is installed or the position is adjusted. The translation structure connected by the hollow concave and the horizontal groove can be horizontally moved along the inner side of the inner frame and the outer frame. Before use, the detection or collection equipment can be directly connected to the translation structure as needed. When the main body of the UAV is flying, the inner frame is retracted into the inner side of the outer frame to reduce the area of ​​the structure, which can reduce air resistance. At the same time, the center of gravity is concentrated as much as possible to be directly below the bottom of the main body of the UAV to maintain flight stability. When the main body of the UAV flies to the measurement and collection position, the inner frame can be controlled to be pulled out from the inner side of the outer frame to expand the working space. The translation structure connected to each device is controlled according to needs. The control motor is rotated forward or reverse. The active shaft connected to the output end drives the roller and the outer friction wheel to rotate through the telescopic rod. The friction wheel contacts the hollow inner concave inside the outer frame or the inner frame, and drives the entire U-shaped frame connected to it along the outer frame and the inner frame through friction. The racks move horizontally to adjust the position of the installed equipment. Since the size of the inner rack is slightly smaller than that of the outer rack, there will be a small height difference when passing through the connection between the inner rack and the outer rack. When the friction wheel and the roller pass through this place, the driving shaft and the driven shaft are limited by the horizontal groove, so the vertical height is inconvenient. When moving to the hollow concave part inside the outer rack, the pressure spring is pressed, and the telescopic rod is forced to retract, so that the roller and the friction wheel rotate eccentrically relative to the driving shaft and the driven shaft, so as to achieve a normal transmission effect. Since the position of the equipment can be freely controlled to move, the distance between the equipment can be controlled to move away from each other when the distance between them is too close. When the center of gravity is offset due to the concentrated position of the equipment between the outer rack and the inner rack on one side, the outer rack and the inner rack on the other side The equipment installed outside the inner frame can move horizontally to coordinate the center of gravity. In addition to serving as the connection between the top structure and the bottom structure, even if the center of gravity of the bottom structure is inconsistent but difficult to adjust, the upper connecting tube, the lower connecting tube and the narrow barrel section will rotate to a certain extent along the rotating shaft, and the airbag as a support can play a certain compensation effect, thereby increasing the allowable error of the structural position adjustment during detection and collection. Since the drone itself will vibrate during continuous operation, the narrow barrel section and the wide section that are the connection positions between the drone and the bottom structure will also vibrate. At this time, the silicone oil will produce viscous resistance to the inner wall of the cavity. Because the internal friction between the silicone oil molecules is large, when the counterweight frame in the cavity moves in the silicone oil along the connecting ball, this viscous resistance needs to be overcome.This resistance will consume the energy of vibration, thus playing a shock-absorbing role. When the UAV is subjected to high-frequency and small-amplitude vibration, silicone oil can effectively suppress the transmission of vibration, reducing the vibration impact on the data acquisition equipment of the bottom structure. Since multiple devices are allowed to operate at the same time, it can also ensure that the data detection and collection positions are close, reducing the error in measurement planning.

The outer sides of the driving shaft 7042 and the driven shaft 7043 are both fixedly connected with a telescopic rod 7047, and the side of the telescopic rod 7047 close to the roller 7044 is fixedly connected to the roller 7044. The outer sides of the driving shaft 7042 and the driven shaft 7043 are both fixedly connected with a pressure spring 7048, and the side of the pressure spring 7048 close to the roller 7044 is fixedly connected to the roller 7044. The pressure spring 7048 is sleeved on the outer side of the telescopic rod 7047, and the bottom of the U-shaped frame 7041 is fixedly connected with an equipment plate 7049; By setting the drone body 1 as a carrier and installing the internal components through the sub-frame 2, the inclined frame 3 can be set to protect the fan blade position of the drone body 1 to avoid injuries when people touch it. The suspension structure 5 is used to connect the drone body 1 and the equipment frame 6. The equipment frame 6 is used to install the collection and detection equipment through the balance frame 7. The outer frame 701 cooperates with the inner frame 702. The inner frame 702 can be withdrawn or retracted from the inner side of the outer frame 701 to adjust the occupied space when the equipment is installed or the position is adjusted. The translation structure 704 connected by the hollow concave and the horizontal groove 703 can be moved along the inner frame 702 and the outer frame 701. 7049 of the translation structure 704. Before use, the detection or collection equipment can be directly assembled with the equipment plate 7049 of the translation structure 704 as needed. When the drone body 1 is flying, the inner frame 702 is retracted into the inner side of the outer frame 701 to reduce the area of ​​the structure, which can reduce the air resistance. At the same time, the center of gravity is concentrated as far as possible to be located directly below the bottom of the drone body 1 to maintain flight stability. When flying to the measurement and collection position, the drone body 1 hovers. At this time, the inner frame 702 can be controlled to be pulled out from the inner side of the outer frame 701 to expand the working space. The translation structure 704 connected to each device can be controlled separately according to needs, and the control motor 7046 can be rotated forward or backward. In reverse, the driving shaft 7042 connected to the output end will drive the roller 7044 and the outer friction wheel 7045 to rotate through the telescopic rod 7047, and the friction wheel 7045 will contact the hollow inner concave of the outer frame 701 or the inner frame 702, and drive the entire U-shaped frame 7041 connected to it to move horizontally along the outer frame 701 and the inner frame 702 through friction, so as to adjust the position of the installed equipment. Since the size of the inner frame 702 is slightly smaller than the outer frame 701, there will be a small height difference when passing through the connection between the inner frame 702 and the outer frame 701. When the friction wheel 7045 and the roller 7044 pass through this place, due to the driving shaft 7042 and the driven shaft 7047 043 is limited by the horizontal groove 703, so the vertical height is inconvenient, and when it moves to the hollow concave part inside the outer frame 701, the pressure spring 7048 is pressed, and the telescopic rod 7047 is forced to retract, so that the roller 7044 and the friction wheel 7045 rotate eccentrically relative to the driving shaft 7042 and the driven shaft 7043, thereby achieving a normal transmission effect. Since the position of the equipment can be freely controlled to move, the distance between the equipment can be controlled to move away from each other when the distance between the equipment is too close.

By setting the slide 9, it is convenient to install the limit frame 10 on the inside of the U-shaped frame 7041. The limit wheel 11 on the inside of the limit frame 10 will always contact the bottom of the outer frame 701 or the inner frame 702 due to the pressure of the hard spring 12, so as to further limit the structure and prevent it from loosening. The inner side of the bottom frame 4 is slidably connected with an extension frame 14, and the bottom of the extension frame 14 is fixedly connected with a foot plate 15. The outer side of the extension frame 14 is sleeved with a buffer spring 16. By setting the extension frame 14 to cooperate with the foot plate 15, the foot plate 15 is used to contact the ground when the drone body 1 is landing. Because it is long, it is not easy to cause the drone body 1 to land on different terrains. The blades are stuck into plants in the ground environment, etc. Since the device may be mounted with too many devices, its own weight is heavy. When landing, the buffer spring 16 arranged is deformed due to the contact with the foot plate 15, so as to avoid the device directly contacting the ground rigidly and causing damage to the equipment. A photovoltaic panel 17 is arranged on the outside of the tilting frame 3. The photovoltaic panel 17 is fixedly connected to a panel bracket 18 on one side close to the tilting frame 3. The panel bracket 18 and the tilting frame 3 are movably connected. By setting the photovoltaic panel 17 in conjunction with the panel bracket 18, the photovoltaic panel 17 can assist in photovoltaic auxiliary energy supply. Its controller, battery and inverter can be installed on the inner side of the sub-frame 2 or at the bottom of the drone body 1, and the panel bracket 18 is used to install and fix the photovoltaic panel 17.

At the same time, when the drone body 1 may collide, the photovoltaic panel 17 directly contacts the force-bearing position to reduce the damage to the drone body 1. The buffer pad 20 provided can play a certain buffering role when subjected to force. Two parallel frames 21 are provided on the inner side of the board support 18, and a protective net 22 is fixedly connected between the opposite sides of the two parallel frames 21. By providing the parallel frames 21 and the protective net 22, the protective net 22 plays a certain protective role on the top of the drone body 1.When operating in complex terrain, the possibility of external impurities falling and being entangled in the blades, causing structural damage or affecting normal operation can be reduced. A through hole is opened on the inner side of the plate bracket 18, and a bolt is provided on the inner side of the plate bracket 18. The side of the bolt close to the through hole passes through the through hole and is threadedly connected to the parallel frame 21. By setting the through hole and the bolt, the protective net 22 can be easily removed together with the parallel frame 21. In locations with open terrain, the structure can be dismantled to reduce the deadweight of the structure, thereby improving the endurance to a certain extent.

[0030] Working principle of this embodiment: According to the measurement and collection requirements, the detection or collection equipment is directly assembled with the equipment plate 7049 of the translation structure 704 to ensure that each device is firmly connected and can work normally. Check the connection status of each component of the device, including the connection between the drone body 1 and the sub-frame 2, the tilt frame 3, the bottom frame 4, the suspension structure 5 and the equipment frame 6 to ensure the firmness of the structure. Control the inner frame 702 to retract into the inner side of the outer frame 701 to reduce the overall area of ​​the structure and reduce air resistance. At the same time, make the center of gravity of the device as far as possible directly below the bottom of the drone body 1 to ensure flight stability. Control the inner frame 702 to retract into the outer frame 701. 01, reducing the overall area of ​​the structure and reducing air resistance. At the same time, the center of gravity of the device is located as far as possible directly below the bottom of the drone body 1 to ensure flight stability. The drone body 1 is started, taken off and flies to the measurement and collection area according to the predetermined route. During the flight, the inner frame 702 remains retracted, and each device is in a relatively compact position. When the drone body 1 flies to the measurement and collection position, it hovers and prepares to carry out measurement and collection operations. The inner frame 702 is controlled to be pulled out from the inside of the outer frame 701 to expand the working space and provide conditions for adjusting the position of the equipment. According to the actual measurement and collection needs, the control and each device are controlled separately. The translation structure 704 connected to the equipment drives the driving shaft 7042 by controlling the forward or reverse rotation of the motor 7046, and drives the roller 7044 and the outer friction wheel 7045 to rotate through the telescopic rod 7047. The friction wheel 7045 contacts the hollow inner concave of the outer frame 701 or the inner frame 702 to drive the entire U-shaped frame 7041 to move horizontally along the outer frame 701 and the inner frame 702, so as to adjust the position of each device. When the distance between the devices is too close, they can be controlled to move away from each other. If the center of gravity is offset due to the concentrated position of the devices on one side, the outer frame 701 and the inner frame 702 on the other side can be used to adjust the position of each device. The mounted equipment moves horizontally to coordinate the center of gravity, ensuring the overall stability of the device, facilitating accurate measurement and collection operations. After completing the measurement and collection tasks, the drone body 1 is controlled to return along the predetermined route and approach the landing site. When approaching the ground, the foot plate 15 at the bottom of the drone body 1 will first touch the ground. Since the extension frame 14 is longer than the foot plate 15, the risk of the blades getting stuck in plants in the ground environment can be reduced when landing on different terrains. At the same time, the buffer spring 16 is deformed due to contact with the foot plate 15 during landing, and the impact force generated by the rigid contact between the buffer device and the ground is avoided. Damage to the mounted equipment is ensured to ensure the safe landing of the device.

[0031] Example 2. Reference Figure 3-7, an aerial photography measurement auxiliary device for land space planning also includes a suspension structure 5, wherein the suspension structure 5 includes an upper connecting tube 501, a lower connecting tube 502 and a narrow barrel section 503, the top of the inner side of the upper connecting tube 501 and the bottom of the inner side of the lower connecting tube 502 are fixedly connected with a rotating shaft 508, the rotating shaft 508 is rotatably connected to the narrow barrel section 503 on one side close to the narrow barrel section 503, a wide section 504 is provided in the middle of the inner side of the narrow barrel section 503, a connecting ball 505 is fixedly connected to the top of the inner wall of the wide section 504, a counterweight frame 506 is slidably connected to the outer side of the connecting ball 505, the inner side of the wide section 504 is filled with silicone oil, the top and bottom of the outer side of the narrow barrel section 503 are fixedly connected with airbags 507, the outer sides of the two airbags 507 are respectively fixedly connected to the upper connecting tube 501 and the lower connecting tube 502, the top of the upper connecting tube 501 is fixedly connected to the drone body 1, and the bottom of the lower connecting tube 502 is fixedly connected to the top of the equipment frame 6; In addition to being the connection between the top structure and the bottom structure, the suspension structure 5 can rotate to a certain extent along the rotating shaft 508 even if the center of gravity of the bottom structure is inconsistent but difficult to adjust, and the airbag 507 can play a certain compensation effect as a support, thereby increasing the allowable error of the structural position adjustment during detection and collection. Since the drone itself will also vibrate during continuous operation, the narrow barrel section 503 and the wide section 504 as the connection position between the drone and the bottom structure will also vibrate accordingly. At this time, the silicone oil will produce viscous resistance to the inner wall of the cavity, because the internal friction between the silicone oil molecules is large. When the counterweight frame 506 in the cavity moves along the connecting ball 505 in the silicone oil, it needs to overcome this viscous resistance, which consumes the energy of the vibration, thereby playing a shock-absorbing effect. When the drone is subjected to high-frequency and small-amplitude vibration, the silicone oil can effectively suppress the transmission of the vibration, thereby reducing the vibration influence on the data acquisition equipment of the bottom structure. Since multiple devices are allowed to operate at the same time, it can also ensure that the data detection and acquisition positions are close, thereby reducing the error during measurement planning.

[0032] Wherein, the equipment frame 6 comprises an empty cylinder 601, the inner side of the empty cylinder 601 is fixedly connected with an electric cylinder 602, the telescopic end of the electric cylinder 602 is fixedly connected with a movable frame 603, the outer side of the movable frame 603 is rotatably connected with an outer support 604, the outer side of the empty cylinder 601 is rotatably connected with an inclined frame 605, the inner side of the inclined frame 605 is rotatably connected with the outer support 604, by arranging the empty cylinder 601 to cooperate with the electric cylinder 602, the electric cylinder 602 is normally in an extended state, at this time the movable frame 603 and the outer support 604 will pull the inclined frame 605 to rotate and tilt along the top of the empty cylinder 601 to keep the bottoms of the inclined frame 605 close to each other, because the inclined frame 605 is connected with the outer frame 701 and the inner frame 702, most of the inner frame 702 is located on the inner side of the outer frame 701 at this time, and when needed When operation is required, the telescopic end of the electric cylinder 602 retracts, which will drive the movable frame 603 to move upward. At this time, the outer support 604 will push the inclined frame 605 to rotate along the empty cylinder 601 to open the structure. At this time, the inner frame 702 is pulled out from the inner side of the outer frame 701 to expand the moving position of the structure. There are four inclined frames 605, and a connecting block 13 is installed at the bottom of the inclined frame 605. The outer sides of the two connecting blocks 13 on the left are rotatably connected to the two outer frames 701 respectively, and the outer sides of the two connecting blocks 13 on the right are rotatably connected to the two inner frames 702 respectively. By setting the connecting block 13, the inclined frame 605 and the inner frame 702 or the outer frame 701 can be reasonably connected, and at the same time, the structures can be reasonably rotated, so that the structure can be transmitted and is not easy to get stuck.

During flight, the upper connecting tube 501, the lower connecting tube 502 and the narrow barrel section 503 of the suspension structure 5 remain relatively stable, relying on the airbag 507 to compensate for the slight center of gravity changes of the bottom structure caused by factors such as airflow, and the silicone oil suppresses the transmission of the drone's own vibration to the equipment frame 6 and the structure below. When the center of gravity of the bottom structure is inconsistent but difficult to adjust, the upper connecting tube 501, the lower connecting tube 502 and the narrow tube section 503 are adapted by rotating to a certain extent along the rotating shaft 508. At the same time, the airbag 507 plays a supporting and compensating role to increase the allowable error of the structural position adjustment during detection and collection. When operation is required, the telescopic end of the electric cylinder 602 is controlled to retract, driving the movable frame 603 to move upward, and then the external support 604 will push the inclined frame 605 to rotate along the empty tube 601, open the structure, and pull the inner frame 702 out from the inner side of the outer frame 701, thereby expanding the mobile position of the structure and facilitating subsequent related operations.
