Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an anti-collision remote sensing unmanned aerial vehicle surveying and mapping device. Background Art

[0002] Mine surveying and mapping refers to the measurement, collection and mapping of the shape, size, spatial position and attributes of natural geographical elements or surface artificial facilities in the mining area. It provides technical services for mine planning and design, exploration and construction, production and operation management, and mine scrapping during mine construction and mining, and is the primary link in mining technology. Traditional surveying and mapping is done manually on foot, with low operating efficiency. Especially when surveying key feature points in complex areas, it faces problems such as difficulty in information collection, great safety hazards, slow progress and high labor intensity, making it difficult to meet the goal of intensive mining.

[0003] The new surveying and mapping technology is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with global navigation satellite positioning system, remote sensing, and geographic information system as the core technology. It selects existing feature points and boundaries on the ground and obtains graphics and location information reflecting the current situation on the ground through measurement. With the popularization and widespread application of drone technology, drone aerial surveys are flexible, efficient, fast, low-cost, and widely applicable. Their superiority in working under harsh conditions continues to be highlighted. In addition, drones have been widely used in surveying and mapping operations instead of manual surveying, and surveying and mapping results have also been improved in quality.

[0004] In the prior art, for example, Chinese patent publication number CN112623215A discloses an anti-collision mapping drone. The device has a simple structure and novel design, can effectively reduce the risk of users being cut by fan blades due to improper operation, and can prevent the drone from hitting birds when taking off, ensuring safety during abnormal landing.

[0005] The above patent protects the propeller by setting an arc-shaped steel frame and an arc-shaped bracket, which has an anti-collision effect. However, the protective structure in the existing anti-collision UAV is connected to the UAV body as a whole and cannot be separated. During the surveying and mapping process in a large mining area, when the UAV collides violently with the mine wall due to improper operation, the protective cover is easily deformed and comes into contact with the propeller, causing the UAV to lose its ability to fly and crash.

[0006] Therefore, an anti-collision remote sensing UAV surveying and mapping device is proposed to solve the problems raised in the above background technology. Summary of the invention

[0007] The purpose of the present invention is to provide an anti-collision remote sensing UAV surveying and mapping device to solve the problem proposed in the above background technology that when the existing anti-collision UAV is surveying and mapping in a large mining area, the protective cover cannot be detached, is easily deformed and contacts the propeller, causing the UAV to crash when it is subjected to a strong collision.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-collision remote sensing UAV surveying and mapping device, comprising a remote sensing UAV body, a surveying and mapping device is installed at a position near the bottom of the front surface of the remote sensing UAV body, a connecting mechanism is installed at the top of the remote sensing UAV body, a trigger mechanism is arranged inside the connecting mechanism, an upper cover mechanism is arranged above the connecting mechanism, a lateral buffer assembly is installed at a position near the outer side of the bottom of the upper cover mechanism, a vertical buffer assembly is arranged between the upper cover mechanism and the outer side of the lateral buffer assembly, a shield assembly is arranged on the outer side of the vertical buffer assembly, and the The connecting mechanism includes a fixed shell, which is fixedly connected to the top of the remote sensing UAV body. A tooth column is rotatably connected at the inner center of the fixed shell. The number of the trigger mechanisms is set to four groups, and the four groups of trigger mechanisms are staggered up and down. The trigger mechanism includes a first sliding plate, and the upper cover mechanism includes an upper plate. The lateral buffer assembly includes four curved plates, and the four curved plates are equidistantly fixedly connected to the bottom of the upper plate near the edge. The vertical buffer assembly includes a vertical frame, and the shield assembly includes an arc cover, and the outer surface of the arc cover is fixedly connected to a connecting frame, and the connecting frame is fixedly connected to the outer surface of the vertical frame.

[0009] Preferably, four groups of second movable grooves are equidistantly provided inside the fixed shell at positions outside the tooth column, first movable grooves are symmetrically provided on the inner surface wall of the second movable groove on the side close to the tooth column, a receiving groove is provided on the inner bottom of the second movable groove, and four slots are equidistantly provided on the top of the fixed shell near the edge, and the slots and the second movable grooves are connected to each other.

[0010] By adopting the above technical solution, four groups of first active grooves and second active grooves are distributed around the outside of the tooth column and are not at the same height and do not interfere with each other. The depth of the four slots is consistent with the depth of the corresponding second active grooves.

[0011] Preferably, the first sliding plate is slidably embedded in the inside of the second movable groove, and the outer surface of the first sliding plate close to the tooth column is symmetrically fixedly connected with a rack and a connecting column, the connecting column is located at the end away from the first sliding plate and is fixedly connected to a limiting block, the limiting block and the rack are symmetrically slidably embedded in the inside of a group of first movable grooves, the rack and the tooth column are meshingly connected, the outer surface of the first sliding plate away from the tooth column extends to the outside of the fixed shell, and the outer surface of the first sliding plate is fixedly connected with an enlargement plate.

[0012] By adopting the above technical solution, due to the height difference of the four first sliding plates, the surface height extending to the outside of the fixed shell is inconsistent. Therefore, the size of the outer surface of the first sliding plate is increased by adding an enlarging plate, and the first sliding plate can be pushed to slide inward when the enlarging plate is squeezed.

[0013] Preferably, a beveled groove is provided on the top of the first sliding plate, and the positions of the beveled groove and the slot correspond to each other. A U-shaped shell is fixedly connected to the bottom of the first sliding plate below the beveled groove, and a spring rod is fixedly connected between the outer surface of the U-shaped shell and the inner surface wall of the accommodating slot. Four clips of inconsistent lengths are fixedly connected at equal distances near the edge of the bottom of the upper plate, and the clips pass through the slot and are snap-fitted to the beveled groove.

[0014] By adopting the above technical solution, the lengths of the four buckles correspond to the depth of the corresponding first sliding plate, and a pointing arrow is provided on the handle. When the arrow is in the same direction as the surveying and mapping equipment, the four buckles will correspond to the four slot positions.

[0015] Preferably, the tops of the four curved plates are rotatably connected to right-angle rotating blocks near the outer edges, and the tops of adjacent right-angle rotating blocks near the outer sides are rotatably connected to planar connecting rods through rotating shafts. The bottom of the planar connecting rod is fixedly connected to the accommodating shell near the middle position, and a top block extending outward is slidably embedded in the interior of the accommodating shell. The top block cooperates with the enlarged plate, and a connecting pipe is fixedly connected to the outer surface of the accommodating shell on a side away from the enlarged plate. The outer surface of the planar connecting rod on a side away from the remote sensing UAV body is symmetrically fixedly connected to a first rotating seat, and the top of the planar connecting rod is movably connected to a first damping member through a universal joint, and the upper end of the first damping member is fixedly connected to the outer surface edge of the upper plate through a universal joint.

[0016] By adopting the above technical solution, four right-angle rotating blocks rotatably connected to the curved plate cooperate with each other, so that the four planar connecting rods form a linkage and can synchronously approach the fixed shell. The first damping member is used to buffer and absorb energy of the planar connecting rods.

[0017] Preferably, vertical sliding rods are symmetrically fixedly connected between the inner walls of the vertical frames, a sliding block is slidably connected between the outer surfaces of the two sliding rods, a resistance rod is fixedly connected to the outer surface of one side of the sliding block, and one end of the resistance rod extends to the interior of the connecting pipe and cooperates with the top block.

[0018] By adopting the above technical solution, the sliding block forms a sliding connection with the vertical frame through the sliding rod. When the vertical frame remains in a vertical state and moves up and down, since one end of the resistance rod on the surface of the sliding block is inserted in the connecting pipe, the sliding block will slide with the vertical frame and the sliding block itself is always in a horizontal state with the connecting pipe.

[0019] Preferably, a lower connecting rod is symmetrically and rotationally connected to a position near the bottom of the outer surface of one side of the vertical frame, the ends of the two lower connecting rods are rotatably connected to a fixing rod, the top of the fixing rod is fixedly connected to the bottom of the planar connecting rod, a cross rod is fixedly connected to a position near the bottom between the outer surfaces of the two fixing rods, an upper connecting rod is symmetrically and rotationally connected to a position near the top of the outer surface of one side of the vertical frame, one end of the upper connecting rod away from the vertical frame is rotatably connected to the first rotating seat, a V-shaped frame is fixedly connected to a position near the middle between the bottoms of the two upper connecting rods, and a second damping member is rotatably connected between the bottom of the V-shaped frame and the outside of the cross rod.

[0020] By adopting the above technical solution, the vertical frame will maintain a vertical state and move up and down after being hit in the vertical direction. In this process, it will approach the planar connecting rod and the fixed shell. At the same time, the vertical frame will transfer the impact force to the planar connecting rod after being hit laterally, thereby driving the planar connecting rod to move along the direction of the lateral impact force. At the same time, the second damping member used for manufacturing will cooperate with the V-shaped frame to buffer and absorb energy of the vertical frame and the external arc cover.

[0021] Preferably, the inner bottom of the U-shaped shell is symmetrically fixedly connected with a first spring, the top of the first spring is fixedly connected with a resistance plate, and the resistance plate is slidably embedded between the inner surface walls of the U-shaped shell and the top is in resistance with the bottom of the buckle.

[0022] By adopting the above technical solution, after the upper plate is fixed to the top of the fixed shell by pressing, the buckle and the oblique groove form a snap fit. During this process, the buckle will press the contact plate downward, and the contact plate will squeeze the first spring to contract and store energy.

[0023] Preferably, a circular shell is fixedly connected to the top center of the upper plate, a rebound rod is slidably arranged between the inner surface walls of the circular shell, a second spring is fixedly connected between the top of the rebound rod and the inner top of the circular shell, the bottom end of the rebound rod is in conflict with the top of the fixed shell, and a handle is fixedly connected to the top of the upper plate located outside the circular shell.

[0024] By adopting the above technical solution, the handle is used to facilitate taking the device, and an arrow is provided on the surface, and the arrow is consistent with the direction of the surveying and mapping equipment.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. When the present invention is used, when the remote sensing UAV body cooperates with the surveying and mapping equipment for surveying, when a strong collision occurs during the ascent and descent process, the shield assembly will drive the vertical frame to move up and down while greatly approaching the fixed shell, and drive the resistance rod to squeeze the top block and then trigger the enlarged plate to separate the buckle from the oblique groove. When the side of the remote sensing UAV body is strongly collided during the forward movement, the planar connecting rod will greatly approach the fixed rod, and drive the top block through the accommodating shell to trigger the increase in plate thickness to separate the buckle from the oblique groove, so that the arc cover of the remote sensing UAV body will be separated from the remote sensing UAV body in time after a strong collision during the flight of the remote sensing UAV body in a large open-pit mining area, so as to avoid contact with the propeller after deformation and cause a crash.

[0027] 2. When the present invention is used, when the arc cover has a slight collision during the ascent and descent of the remote sensing UAV body, the vertical frame will be driven to move up and down through the connecting frame. During this process, the second damping member between the cross bar and the V-shaped frame will buffer and absorb energy by extension and contraction. After a lateral collision during the forward movement, the planar connecting rod will move horizontally and approach the fixed shell. During this process, the two first damping members between each planar connecting rod and the upper plate will extend and contract to buffer and absorb energy, which can effectively reduce the damage caused by the collision of the arc cover during the flight of the remote sensing UAV body.

[0028] 3. When the present invention is used, when the remote sensing UAV body is subjected to a strong collision during flight, causing the buckle to separate from the receiving groove on the surface of the first movable plate, the energy-storing first spring will stretch and release energy to push the buckle upward, promoting the remote sensing UAV body and the connecting mechanism and the protective mechanism. At the same time, the energy-storing second spring will stretch and release energy to push the circular shell and the upper plate upward, and cooperate with each other to ensure that the arc cover can be effectively separated from the remote sensing UAV body when subjected to a severe collision.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1: Please refer to Figure 1-Figure 14As shown, the present invention provides a technical solution: an anti-collision remote sensing UAV surveying and mapping device, comprising a remote sensing UAV body 1, a surveying and mapping device 11 is installed at a position near the bottom of the front surface of the remote sensing UAV body 1, a connecting mechanism 2 is installed on the top of the remote sensing UAV body 1, a trigger mechanism 3 is arranged inside the connecting mechanism 2, an upper cover mechanism 4 is arranged above the connecting mechanism 2, a lateral buffer component 5 is installed at a position near the outside of the bottom of the upper cover mechanism 4, a vertical buffer component 6 is arranged between the upper cover mechanism 4 and the outside of the lateral buffer component 5, a shield component 7 is arranged on the outside of the vertical buffer component 6, and the connecting mechanism 2 includes The fixed shell 201 is fixedly connected to the top of the remote sensing drone body 1, and a tooth column 206 is rotatably connected at the inner center of the fixed shell 201. The number of trigger mechanisms 3 is set to four groups, and the four groups of trigger mechanisms 3 are staggered up and down. The trigger mechanism 3 includes a first sliding plate 301, and the upper cover mechanism 4 includes an upper plate 401. The lateral buffer assembly 5 includes four curved plates 501, and the four curved plates 501 are equidistantly fixedly connected to the bottom of the upper plate 401 near the edge. The vertical buffer assembly 6 includes a vertical frame 601, and the shield assembly 7 includes an arc cover 701, and the outer surface of the arc cover 701 is fixedly connected to a connecting frame 702. The connecting frame 702 is fixedly connected to the outer surface of the vertical frame 601. The remote sensing UAV body 1 is a device that combines remote sensing technology with UAV technology. It is mainly composed of UAV, remote sensing sensor, data transmission system and ground control station. It has high sensitivity. After combining with the surveying and mapping equipment 11, it can better complete the surveying and mapping of large open-pit mines. It is an existing mature technology and will not be described in detail here. The connecting mechanism 2 cooperates with the trigger mechanism 3 to form a connecting seat for installing the protective mechanism. It is installed on the top of the remote sensing UAV body 1. The upper cover mechanism 4, the lateral buffer assembly 5, the vertical buffer assembly 6 and the shield assembly 7 form a protective mechanism. The cover mechanism 4 cooperates with the connecting mechanism 2 to form a connection with the remote sensing UAV body 1, and the lateral buffer assembly 5 and the vertical buffer assembly 6 cooperate to buffer the shield assembly 7 in the horizontal and vertical directions, wherein the stiffness coefficient of the rebound rod 406 is greater than the stiffness coefficient of the first damping member 505 and the second damping member 607. Therefore, when the arc cover 701 is subjected to a normal impact, the first damping member 505 and the second damping member 607 will buffer and absorb energy by expansion and contraction. When subjected to a severe impact, the rebound rod 406 will be squeezed by the U-shaped shell 307 and shrink, thereby causing the oblique groove 302 and the buckle 403 to lose connection.

[0046] Four groups of second movable grooves 205 are equidistantly provided inside the fixed shell 201 at positions outside the tooth column 206, first movable grooves 203 are symmetrically provided on the inner surface wall of the second movable groove 205 on the side close to the tooth column 206, and a receiving groove 204 is provided on the inner bottom of the second movable groove 205. Four slots 202 are equidistantly provided on the top of the fixed shell 201 near the edge, and the slots 202 and the second movable grooves 205 are interconnected. The four groups of first movable grooves 203 and second movable grooves 205 are distributed around the outside of the tooth column 206, and are not at the same height and do not interfere with each other. The depths of the four slots 202 are consistent with the depths of the corresponding second movable grooves 205.

[0047] The first sliding plate 301 is slidably embedded in the second movable groove 205, and the outer surface of the first sliding plate 301 close to the tooth column 206 is symmetrically fixedly connected with a rack 304 and a connecting column 305. The connecting column 305 is located at an end away from the first sliding plate 301 and is fixedly connected with a limiting block 306. The limiting block 306 and the rack 304 are symmetrically slidably embedded in a group of first movable grooves 203. The rack 304 and the tooth column 206 are meshed and connected. The outer surface of the first sliding plate 301 away from the tooth column 206 extends to the outside of the fixed shell 201, and the outer surface of the first sliding plate 301 is fixedly connected with an enlargement plate 303. The second movable groove 205 is mainly used to accommodate the first sliding plate 301, and the first sliding plate 301 can slide inward for a distance. The limit block 306 connected to the first sliding plate 301 through the connecting column 305 is mainly used for limiting in cooperation with the corresponding first movable groove 203, so that the first sliding plate 301 can slide stably. Since there is a height difference between the four first sliding plates 301, the surface height extending to the outside of the fixed shell 201 is inconsistent. Therefore, the size of the outer surface of the first sliding plate 301 is increased by adding the enlargement plate 303, and the first sliding plate 301 can be pushed to slide inward when the enlargement plate 303 is squeezed.

[0048] The top of the first sliding plate 301 is provided with an oblique groove 302, and the positions of the oblique groove 302 and the slot 202 correspond to each other. The bottom of the first sliding plate 301 is located below the oblique groove 302 and is fixedly connected with a U-shaped shell 307. A spring rod 310 is fixedly connected between the outer surface of the U-shaped shell 307 and the inner surface wall of the receiving slot 204. Four buckles 403 of different lengths are fixedly connected at equal distances near the edge of the bottom of the upper plate 401. The buckles 403 pass through the slot 202 and are connected with the oblique groove. The groove 302 is snap-fitted, the oblique groove 302 is consistent in width with the slot 202, the length of the oblique groove 302 is greater than the length of the slot 202, and the position of the oblique groove 302 close to the tooth column 206 is inclined, which is convenient for connection with the buckle 403. The length of the four buckles 403 corresponds to the depth of the corresponding first sliding plate 301, and a pointing arrow is provided on the handle 402. When the arrow is consistent with the direction of the surveying and mapping equipment 11, the four buckles 403 will correspond to the positions of the four slots 202.

[0049] The tops of the four curved plates 501 are rotatably connected to right-angle rotating blocks 502 near the outer edges, and the tops of adjacent right-angle rotating blocks 502 near the outer sides are rotatably connected to planar connecting rods 503 through rotating shafts. The bottoms of the planar connecting rods 503 are fixedly connected to the accommodating shell 506 near the middle position, and a top block 507 extending outward is slidably embedded in the interior of the accommodating shell 506. The top block 507 cooperates with the enlarged plate 303. The outer surface of the accommodating shell 506 on the side away from the enlarged plate 303 is fixedly connected to a connecting pipe 508. The outer surface of the planar connecting rod 503 on the side away from the remote sensing UAV body 1 is symmetrically fixedly connected to a first rotating seat 504. The top of the planar connecting rod 503 is movably connected to a first damping member 505 through a universal joint. The upper end of the first damping member 505 is fixedly connected to the outer surface edge of the upper plate 401 through a universal joint. The curved plate 501 is mainly used for The right-angle rotating block 502 is installed below the upper plate 401 and extends outward. The spacing between the rotating points of adjacent right-angle rotating blocks 502 near the right-angle position is consistent with the spacing between the rotating points near the outer end. Therefore, the rotating points between adjacent right-angle rotating blocks 502 will form a parallelogram. After the rotating points at the outer end positions are connected through the planar connecting rod 503, the planar connecting rod 503 will be subjected to an oblique thrust and will cooperate with the right-angle rotating block 502 to drive all the planar connecting rods 503 to move synchronously toward the fixed shell 201. The distance between the bottom ends of the two first damping members 505 on the same planar connecting rod 503 is smaller than the distance between the top ends, thereby providing a push for the planar connecting rod 503, so that it will move away from the fixed shell 201 when it is not under force, and when the planar connecting rod 503 moves obliquely and approaches the fixed shell 201, the two first damping members 505 will expand and contract, providing a buffering effect in the process.

[0050] Vertical sliding rods 608 are symmetrically fixedly connected between the inner walls of the vertical frame 601, and a sliding block 609 is slidably connected between the outer surfaces of the two sliding rods 608. A resistance rod 610 is fixedly connected to the outer surface of one side of the sliding block 609, and one end of the resistance rod 610 extends to the interior of the connecting pipe 508 and cooperates with the top block 507. The sliding block 609 forms a sliding connection with the vertical frame 601 through the sliding rod 608. When the vertical frame 601 maintains a vertical state and moves up and down, since one end of the resistance rod 610 on the surface of the sliding block 609 is inserted into the connecting pipe 508, the sliding block 609 will slide with the vertical frame 601, and the sliding block itself is always in a horizontal state with the connecting pipe 508.

[0051] The outer surface of one side of the vertical frame 601 is symmetrically rotatably connected to a lower connecting rod 602 near the bottom, and the ends of the two lower connecting rods 602 are rotatably connected to fixed rods 603. The top of the fixed rod 603 is fixedly connected to the bottom of the plane connecting rod 503. A cross bar 604 is fixedly connected to the outer surfaces of the two fixed rods 603 near the bottom. The outer surface of one side of the vertical frame 601 is symmetrically rotatably connected to an upper connecting rod 605 near the top. One end of the upper connecting rod 605 away from the vertical frame 601 is rotatably connected to the first rotating seat 504. The fixed rods 603 are fixed to the bottom of the plane connecting rod 503 in groups of two, and the fixed rods 603 are rotatably connected to the vertical frame 601 through the lower connecting rod 602. The vertical frame 601 is rotatably connected with the first rotating seat 504 through the upper connecting rod 605, and the upper connecting rod 605 and the lower connecting rod 602 are of the same length, and the distance between the rotating points at both ends of the upper connecting rod 605 is consistent with the distance between the rotating points at both ends of the lower connecting rod 602. Therefore, the upper connecting rod 605 and the lower connecting rod 602 will rotate synchronously and always remain in a parallel state. After the vertical frame 601 is hit in the vertical direction, it will remain in a vertical state and move up and down. In this process, it will approach the planar connecting rod 503 and the fixed shell 201. At the same time, after the vertical frame 601 is hit laterally, the impact force will be transmitted to the planar connecting rod 503, thereby driving the planar connecting rod 503 to move along the direction of the lateral impact force.

[0052] A V-shaped frame 606 is fixedly connected near the middle between the bottoms of the two upper connecting rods 605, and a second damping member 607 is rotatably connected between the bottom of the V-shaped frame 606 and the outside of the cross bar 604. The bottom of the second damping member 607 is rotatably connected to the cross bar 604, and the top is inclined toward the outside and upward. At the same time, the top of the second damping member 607 is rotatably connected to the V-shaped frame 606 fixed to the bottoms of the two upper connecting rods 605. The inclined second damping member 607 plays a supporting role, and when the vertical frame 601 moves up and down, the upper connecting rod 605 will rotate, and the rotation of the upper connecting rod 605 will drive the second damping member 607 to extend and retract. At this time, the second damping member 607 will buffer and absorb energy through extension and retraction.

[0053] The use steps of the present invention are as follows: when in use, the buckle 403 at the bottom of the upper plate 401 is inserted into the slot 202 corresponding to the surface of the fixed shell 201. As the buckle 403 is inserted, the bottom end of the buckle 403 passes through the oblique groove 302 at the top of the first sliding plate 301, which squeezes the first sliding plate 301 to move inwardly of the fixed shell 201 and drives the U-shaped shell 307 at the bottom to squeeze the spring rod 310 to contract. When the bottom end of the buckle 403 moves below the oblique groove 302, the spring rod 310 rebounds and pushes the first sliding plate 301 to reset, thereby making the buckle 403 and the oblique groove 302 form an engagement. At this time, the assembly of the device is completed. When the remote sensing drone body 1 cooperates with the surveying and mapping equipment 11 to perform surveying and mapping, it is subjected to the impact of mine walls and bird species during ascending and descending flights. When there is a collision such as the above, the arc cover 701 will protect the propeller and will be hit first. At this time, the connecting frame 702 will transfer the vertical collision force to the vertical frame 601. At this time, the vertical frame 601 will maintain a vertical state and move up and down under the action of the upper connecting rod 605 and the lower connecting rod 602. In the process of up and down movement, the second damping member 607 between the V-shaped frame 606 and the cross bar 604 below the upper connecting rod 605 will expand and contract due to the push and pull force, and play a role in buffering and absorbing energy during the expansion and contraction process, thereby playing the role of buffering the collision force of the arc cover 701 in the up and down directions, reducing the collision damage to the arc cover 701 and the remote sensing UAV body 1, and the remote sensing UAV body 1 carries the surveying and mapping equipment 11 for horizontal During the flight, when the arc cover 701 is subjected to a lateral collision force, the arc cover 701 will transfer the force generated by the collision to the plane connecting rod 503 through the vertical buffer assembly 6. At this time, the plane connecting rod 503 subjected to the lateral force will form a pulling force on the right-angle rotating block 502 at both ends, and cause the right-angle rotating block 502 and the curved plate 501 to rotate, thereby causing the four plane connecting rods 503 to be linked and approach the fixed shell 201 at the same time. During this process, the two inclined first damping members 505 on each plane connecting rod 503 will expand and contract, and buffer and absorb energy during the expansion and contraction process, thereby offsetting a part of the collision force on the arc cover 701, achieving a buffering and energy absorption effect, and reducing the impact on the arc cover 7 01 and the collision damage of the remote sensing UAV body 1. At the same time, when the remote sensing UAV body 1 flies forward too fast and collides violently with the mine wall, the planar connecting rod 503 will greatly approach the fixed shell 201. At this time, the containing shell 506 at the bottom of the planar connecting rod 503 will move with it, and the inner wall of the containing shell 506 squeezes the top block 507, causing the top block 507 to squeeze the enlarged plate 303 to fit the surface of the fixed shell 201. At this time, when the pressure generated by the U-shaped shell 307 at the bottom of the first sliding plate 301 on the spring rod 310 exceeds the elastic limit force of the spring rod 310, the first sliding plate 301 will approach the center of the fixed shell 201, and the rack 304 on the surface of the first sliding plate 301 will drive the tooth column 206 to rotate during the movement.When the tooth column 206 rotates, it will drive the other three sets of racks 304 to move inward synchronously, so that all the first sliding plates 301 are further synchronized. After the first sliding plate 301 moves inward, the oblique groove 302 will separate from the buckle 403. At this time, the remote sensing drone body 1 and the connecting mechanism 2 will separate from other mechanisms. During the ascent and descent of the remote sensing drone body 1, a strong collision will cause the arc cover 701 and the vertical frame 601 to move up and down significantly. At this time, the vertical frame 601 will be significantly close to the fixed shell 201. In this process, the sliding block 609 moves on the sliding rod The surface of 608 slides, so that the resistance rod 610 will not move up and down with the vertical frame 601, and as the vertical frame 601 approaches the fixed shell 201, the resistance rod 610 will eventually pass through the connecting pipe 508 and squeeze the top block 507 inside the containing shell 506 outward, thereby prompting the top block 507 to push the sliding rod 608 to slide, so that the remote sensing UAV body 1 and the connecting mechanism 2 are separated from the protective mechanism. This design allows the arc cover 701 to be separated from the remote sensing UAV body 1 in time after a strong collision during the flight of the remote sensing UAV body 1, avoiding contact with the propeller after deformation and causing a crash.

[0054] Embodiment 2: Figure 5-Figure 7 As shown, the difference between the embodiment and the base is that the inner bottom of the U-shaped shell 307 is symmetrically fixedly connected with the first spring 308, and the top of the first spring 308 is fixedly connected with the contact plate 309, the contact plate 309 is slidably embedded between the inner surface walls of the U-shaped shell 307 and the top and the bottom of the buckle 403 are in conflict, and after the upper plate 401 is fixed to the top of the fixed shell 201 by pressing, the buckle 403 and the oblique groove 302 form a snap fit, and during this process, the buckle 403 will squeeze the contact plate 309 downward, and the contact plate 309 will squeeze the first spring 308 to contract and store energy.

[0055] The steps of using the present invention are as follows: when the buckle 403 passes through the slot 202 and is engaged with the oblique groove 302 on the surface of the first sliding plate 301, the bottom end of the buckle 403 will simultaneously squeeze the contact plate 309 and cause the first spring 308 to contract and store energy. When the arc cover 701 and the remote sensing UAV body 1 are separated, the first sliding plate 301 will first move and separate the oblique groove 302 from the buckle 403. At this time, the first spring 308 stretches and releases energy, thereby pushing the buckle 403 to quickly separate from the first sliding plate 301, ensuring that the arc cover 701 can be effectively separated when subjected to a severe impact.

[0056] Embodiment 3: Figure 1-Figure 4 and Fig. 9As shown, the difference between the basis of the embodiment is that a circular shell 404 is fixedly connected to the top center of the upper plate 401, and a rebound rod 406 is slidably arranged between the inner surface walls of the circular shell 404, and a second spring 405 is fixedly connected between the top of the rebound rod 406 and the inner top of the circular shell 404, and the bottom end of the rebound rod 406 conflicts with the top of the fixed shell 201, and a handle 402 is fixedly connected to the top of the upper plate 401 located outside the circular shell 404. After the upper plate 401 is fixed to the top of the fixed shell 201, the bottom end of the rebound rod 406 will conflict with the top of the fixed shell 201 and be squeezed, so the rebound rod 406 will slide upward, and at this time the top of the rebound rod 406 will squeeze the second spring 405 to contract and store energy. After the upper plate 401 is installed, the handle 402 serves to facilitate the taking of the device, and the arrow on the handle 402 is consistent with the direction of the surveying and mapping equipment 11, which serves as a pointing function.

[0057] The steps of using the present invention are as follows: when the upper plate 401 and the fixed shell 201 are connected, the rebound rod 406 will come into conflict with the top of the fixed shell 201 and squeeze the second spring 405 to contract and store energy. When the upper plate 401 and the fixed shell 201 are separated, the second spring 405 will instantly stretch and release energy, thereby pushing the upper plate 401 upward, so that the arc cover 701 can be effectively separated from the remote sensing drone body 1 when it is subjected to a severe impact.

[0058] Among them, the remote sensing UAV body 1 and the surveying and mapping equipment 11 are both existing technologies, and their components and operating principles are public technologies, so no excessive explanation will be given here.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
