Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and more particularly to a geographical surveying and mapping unmanned aerial vehicle capable of preventing rolling collision. Background Art

[0002] When conducting geographic surveying and mapping, surveying instruments are often needed. However, in some places, the terrain is complex, and it is very laborious to carry surveying instruments manually. With the development of drone technology, surveying and mapping has been greatly facilitated. Now people use drones to survey and map geography, which greatly improves the efficiency of geographic surveying and mapping.

[0003] When using traditional geographic surveying and mapping UAVs, there is a risk of the UAV falling due to operator errors and various environmental factors. However, most existing geographic surveying and mapping UAVs do not have protective devices, which causes damage to the surveying and mapping camera and loss of surveying and mapping data after the UAV falls, resulting in the failure of geographic surveying and mapping work and inconvenience for users.

[0004] After searching, a Chinese patent with authorization announcement number CN219821769U discloses a geographic mapping UAV. In this structure, when the speed sensor and the distance sensor detect that the state of the UAV body exceeds the safety value, the electric slide rail is started, the slide slides outside the electric slide rail, the first rotating shaft moves, the connecting rod moves, the second rotating shaft moves, the sliding block starts to move, the fixed plate moves, the air pump moves, the airbag moves, the air pump is started, and the airbag is inflated. Through the provided buffer component, when the UAV body accidentally falls, the mapping camera at the bottom of the UAV body can be protected by the airbag, effectively avoiding the disadvantage that the mapping camera will be damaged if the UAV body accidentally falls, which can easily lead to the loss of mapping content. When the mapping camera needs to be rotated, the electric remote control shaft is started first, and then the mapping camera starts to rotate. Through the rotation of the mapping camera, the geographic features can be better mapped, which greatly increases the accuracy of geographic mapping.

[0005] However, when this structure is actually used, geographic mapping is carried out through the mapping camera on the drone. The drone often encounters strong winds and unstable airflow conditions during flight, and the mapping camera on the drone is completely exposed to the air. The inflated airbag is set at the bottom of the fixed plate. The airbag cannot have direct contact with the surface of the mapping camera. When encountering airflow impact, the airbag cannot immediately buffer the impact force on the camera surface, thereby affecting the use effect. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a geographic surveying and mapping UAV with anti-rolling and impact protection to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A geographic surveying and mapping UAV with rolling and impact resistance comprises a UAV main body, a support tube is fixedly arranged at the bottom of the UAV main body, a surveying and mapping camera is fixedly arranged at the bottom of the support tube, and a protective mechanism is arranged outside the surveying and mapping camera;

[0009] The protection mechanism includes a first protection frame which is sleeved on the outside of the surveying and mapping camera, a connection groove is opened on the surface of the first protection frame, a connection plate is inserted inside the connection groove, a second protection frame is fixedly provided on one side of the connection plate, air pumps are fixedly provided on the tops of the connection plate and the second protection frame, two delivery pipes are fixedly provided on the output end of the air pump, a first air bag is penetrated at one end of the two delivery pipes, a connection pipe is penetrated at the bottom of the first air bag, a second air bag is penetrated at one end of the connection pipe, the first air bag and the second air bag are connected to the surface of the first protection frame and the second protection frame, a plurality of reinforcement strips are fixedly provided inside the first protection frame and the second protection frame, and a sponge layer is fixedly provided on one side of the first protection frame and the second protection frame.

[0010] By adopting the above technical solution: the overall structural strength is enhanced, and the sponge layer cushions slight collisions, effectively forming a buffer layer outside the surveying and mapping camera, dispersing the impact force, and comprehensively protecting the surveying and mapping camera from rolling impact damage.

[0011] As a further description of the above technical solution: an auxiliary mechanism is arranged inside the first protective frame, and the auxiliary mechanism includes a support frame fixedly arranged inside the first protective frame and the second protective frame, a heat conducting plate is fixedly arranged inside the support frame, and a plurality of fins are fixedly arranged on the bottom of the heat conducting plate, heat dissipation ports are provided on the surfaces of the first protective frame and the second protective frame, and the fins are arranged inside the heat dissipation ports, and an installation groove is provided on the surface of the second protective frame, and the surveying and mapping camera matches the installation groove.

[0012] By adopting the above technical solution: the working heat of the surveying and mapping camera can be transferred to the fins, and efficient heat dissipation can be achieved through the heat dissipation port and airflow, ensuring that the camera can operate stably at an appropriate temperature. At the same time, the mounting slot matches the camera, so that the camera is installed firmly, ensuring that the camera position is fixed during the protection and heat dissipation process, and improving the reliability and stability of the overall protection and heat dissipation.

[0013] As a further description of the above technical solution: two limit grooves are provided on the surface of the connecting plate, and limit rods are inserted into the inside of the two limit grooves, and two U-shaped frames are fixedly provided at the bottom of the first protective frame, and guide plates are slidably provided inside the two U-shaped frames, and a spring is fixedly provided at one end of the guide plate, and one end of the spring is connected to the inner wall of the U-shaped frame, one end of the limit rod passes through the U-shaped frame and extends to the outside of the U-shaped frame, and a handle is fixedly provided at one end of the limit rod.

[0014] By adopting the above technical solution, the connection and separation of the first protective frame and the second protective frame can be flexibly realized, which is convenient for installing, maintaining or replacing the surveying and mapping camera.

[0015] As a further description of the above technical solution: two supporting legs are fixedly provided at the bottom of the drone body, and a rubber layer is fixedly provided at the bottom of the two supporting legs.

[0016] By adopting the above technical solution: the landing safety is effectively improved. The support legs provide stable support for the landing of the drone, ensuring the stability of the fuselage. The bottom rubber layer can buffer the instantaneous impact of landing, reduce damage to the drone as a whole and key components, and extend the service life of the equipment.

[0017] Technical effects and advantages of the present invention:

[0018] 1. By setting up a protective mechanism, compared with the prior art, the physical protective shell formed by the first protective frame and the second protective frame can block direct external collision and friction. The internal reinforcement strip enhances the structural strength of the protective frame and improves the impact resistance. The sponge layer on one side can buffer in the event of a slight collision and reduce the impact force transmission. Secondly, when facing the risk of rolling collision, the air pump inflates the first airbag and the second airbag to form a buffer layer around the camera, further enhancing the protection, effectively buffering the impact force in all directions, reducing the risk of damage, avoiding rigid collision directly acting on the camera, protecting the internal precision components, and providing comprehensive protection for the mapping camera from multiple aspects to ensure its stable operation under complex flight conditions;

[0019] 2. By setting up auxiliary mechanisms, compared with the existing technology, the heat conduction plate in the support frame can conduct the heat generated by the mapping camera and transfer it to the fins. The heat dissipation ports on the surface of the protective frame cooperate with the fins, and with the help of natural convection and flight airflow, the camera heat can be effectively dissipated, ensuring that it can work stably at an appropriate temperature, avoiding performance degradation or component damage due to overheating, and ensuring the continuity and accuracy of mapping work. In addition, by pulling the handle to move the limit rod, the first protective frame can be easily separated from the second protective frame, which is convenient for maintenance or replacement of parts, and the operation is convenient and fast.

[0020] 3. By setting the support legs, rubber layer and drone body, compared with the existing technology, the support legs and rubber layer design at the bottom of the drone provide strong protection for landing safety. The support legs firmly support the drone body during landing to ensure its stable posture. The bottom rubber layer can effectively absorb and buffer the strong impact force at the moment of landing with good elasticity, which not only greatly reduces the impact on the drone as a whole, but also focuses on protecting the fragile mapping camera and its protective mechanism at the bottom, avoiding damage to internal components due to landing impact, extending the service life of the equipment, and ensuring the smooth development of geographic surveying and mapping work.

[0027] 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 described embodiments 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.

[0028] The embodiments of this application disclose Figure 1-5 The anti-rolling and impact geographic surveying and mapping UAV shown in the figure comprises a UAV body 1, a support tube 2 is fixedly arranged at the bottom of the UAV body 1, a surveying and mapping camera 3 is fixedly arranged at the bottom of the support tube 2, and a protective mechanism is arranged outside the surveying and mapping camera 3;

[0029] The protection mechanism includes a first protection frame 4 sleeved on the outside of the surveying and mapping camera 3, a connection groove 5 is opened on the surface of the first protection frame 4, a connection plate 6 is inserted in the connection groove 5, a second protection frame 7 is fixedly arranged on one side of the connection plate 6, an air pump 8 is fixedly arranged on the top of the connection plate 6 and the second protection frame 7, two delivery pipes 9 are fixedly arranged on the output end of the air pump 8, a first air bag 10 is penetrated at one end of the two delivery pipes 9, a connecting pipe 11 is penetrated at the bottom of the first air bag 10, a second air bag 12 is penetrated at one end of the connecting pipe 11, the first air bag 10 and the second air bag 12 are connected to the surface of the first protection frame 4 and the second protection frame 7, and the first air bag 10 and the second air bag 12 are connected to the surface of the first protection frame 4 and the second protection frame 7. A plurality of reinforcing strips 13 are fixedly arranged inside the first protective frame 4 and the second protective frame 7, and a sponge layer 14 is fixedly arranged on one side of the first protective frame 4 and the second protective frame 7. The first protective frame 4 and the second protective frame 7 together form a protective shell for the surveying and mapping camera 3, which plays a certain physical protection role for the surveying and mapping camera 3 to prevent it from being directly subjected to external collision and friction. In addition, the plurality of reinforcing strips 13 inside the first protective frame 4 and the second protective frame 7 provide structural strength for the first protective frame 4 and the second protective frame 7, and enhance their anti-collision ability. At the same time, the sponge layer 14 on one side thereof can play a buffering role when subjected to a slight collision, thereby reducing the transmission of impact force to the surveying and mapping camera 3:

[0030] When the UAV may face the risk of rolling impact during flight, the air pump 8 is started, and the air pump 8 inflates the first airbag 10 through the two delivery pipes 9 at the output end. Since the first airbag 10 and the second airbag 12 are interconnected through the connecting pipe 11, the gas will fill the first airbag 10 and the second airbag 12. Since the first airbag 10 and the second airbag 12 are connected to the surface of the first protective frame 4 and the second protective frame 7, an inflatable buffer layer is formed around the surveying and mapping camera 3, further enhancing the protection effect. The first airbag 10 and the second airbag 12 protect the surface of the first protective frame 4 and the second protective frame 7, which can effectively buffer the impact force from all directions and reduce the risk of damage to the surveying and mapping camera 3 due to rolling impact.

[0031] Reference Figure 3 , 4As shown in , 5, an auxiliary mechanism is arranged inside the first protective frame 4, and the auxiliary mechanism includes a support frame 15 fixedly arranged inside the first protective frame 4 and the second protective frame 7, a heat conducting plate 16 is fixedly arranged inside the support frame 15, and a plurality of fins 17 are fixedly arranged at the bottom of the heat conducting plate 16, and heat dissipation ports are provided on the surfaces of the first protective frame 4 and the second protective frame 7, and the fins 17 are arranged inside the heat dissipation ports. A mounting groove is provided on the surface of the second protective frame 7, and the surveying and mapping camera 3 matches the mounting groove. The support frame 15 is fixed inside the first protective frame 4 and the second protective frame 7, and the heat conducting plate 16 inside it is used to conduct the heat generated when the surveying and mapping camera 3 is working. The heat is transferred to the plurality of fins 17 through the heat conducting plate 16. Since the surfaces of the first protective frame 4 and the second protective frame 7 are provided with heat dissipation ports, and the fins 17 are arranged inside the heat dissipation ports, the heat can be dissipated from the fins 17 through natural convection or airflow during flight, thereby realizing the heat dissipation of the surveying and mapping camera 3 and ensuring that the surveying and mapping camera 3 works normally within a suitable temperature range.

[0032] Reference Figure 4 , 5 As shown, two limiting grooves 18 are provided on the surface of the connecting plate 6, and limiting rods 19 are inserted inside the two limiting grooves 18. Two U-shaped frames 20 are fixedly provided at the bottom of the first protective frame 4, and guide plates 21 are slidably provided inside the two U-shaped frames 20. A spring 22 is fixedly provided at one end of the guide plate 21, and one end of the spring 22 is connected to the inner wall of the U-shaped frame 20. One end of the limiting rod 19 passes through the U-shaped frame 20 and extends to the outside of the U-shaped frame 20. A handle 23 is fixed at one end of the limiting rod 19. Since the limiting rod 19 is inserted in the two limiting grooves 18 provided on the surface of the connecting plate 6, the limiting rod 19 passes through the U-shaped frame 20 at the bottom of the first protective frame 4. In the initial state, the spring 22 is in a natural state, and the guide plate 21 is located on the inner side of the U-shaped frame 20. Then, the handle 23 is pulled to drive the limiting rod 19 to slide outward, compress the spring 22, and cause the limiting rod 19 to move. Then, the second protective frame 7 is connected to the connecting plate 6 through the connecting plate 6. The first protective frame 4 is connected, and the connecting plate 6 is inserted into the connecting groove 5 to achieve relative fixation of the second protective frame 7 and the first protective frame 4. When the connecting plate 6 is fully inserted into the connecting groove 5, the handle 23 is released, and the elastic force of the spring 22 will push the guide plate 21 and the limit rod 19 to reset, so that the limit rod 19 is inserted into the limit groove 18 to ensure the connection stability of the second protective frame 7 and the first protective frame 4. The support frame 15 is fixed inside the first protective frame 4 and the second protective frame 7. The heat conducting plate 16 inside it is used to conduct the heat generated when the surveying and mapping camera 3 is working. The heat is transferred to the multiple fins 17 through the heat conducting plate 16. Since the surfaces of the first protective frame 4 and the second protective frame 7 are provided with heat dissipation ports, the fins 17 are arranged inside the heat dissipation ports. Through natural convection or airflow during flight, heat can be dissipated from the fins 17 to achieve heat dissipation of the surveying and mapping camera 3 and ensure that the surveying and mapping camera 3 works normally within a suitable temperature range.

[0033] Reference Figure 1 As shown, two supporting legs 24 are fixedly provided at the bottom of the drone body 1, and a rubber layer 25 is fixedly provided at the bottom of the two supporting legs 24. The two supporting legs 24 at the bottom of the drone body 1 are used to support the entire drone body 1 when the drone lands, and the rubber layer 25 at the bottom of the supporting legs 24 plays a buffering role. When the drone body 1 lands and contacts the ground, the rubber layer 25 can absorb and buffer the impact force at the moment of landing, reduce the impact on the drone as a whole, and prevent damage to internal components caused by the landing impact, especially damage to the mapping camera 3 and its protective mechanism at the bottom.

[0034] Working principle of the present invention:

[0035] The present invention is a geographic surveying and mapping drone for preventing rolling and collision. When the device is in use, the limiting rod 19 is inserted into the two limiting grooves 18 opened on the surface of the connecting plate 6, and the limiting rod 19 passes through the U-shaped frame 20 at the bottom of the first protective frame 4. In the initial state, the spring 22 is in a natural state, and the guide piece 21 is located in the U-shaped frame 20. Then, the handle 23 is pulled to drive the limiting rod 19 to slide outward, compressing the spring 22 so that the limiting rod 19 moves. Then, the second protective frame 7 is connected to the first protective frame 4 through the connecting plate 6, and the connecting plate 6 is inserted into the connecting groove 5 to achieve relative fixation of the second protective frame 7 and the first protective frame 4. When the connecting plate 6 is completely inserted into the connecting groove 5, the handle 23 is released, and the elastic force of the spring 22 will push the guide piece 21 and the limiting rod 19 to reset, so that the limiting rod 19 is inserted into the limiting groove 18, thereby ensuring the connection stability of the second protective frame 7 and the first protective frame 4.

[0036] The first protective frame 4 and the second protective frame 7 together form a protective shell for the surveying and mapping camera 3, which plays a certain physical protective role for the surveying and mapping camera 3 to prevent it from being directly impacted and rubbed by the outside world. In addition, the multiple reinforcing bars 13 inside the first protective frame 4 and the second protective frame 7 provide structural strength for the first protective frame 4 and the second protective frame 7 to enhance their anti-impact ability. At the same time, the sponge layer 14 on one side can play a buffering role when slightly impacted, thereby reducing the impact force transmission to the surveying and mapping camera 3:

[0037] When the drone may face the risk of rolling collision during flight, the air pump 8 is started, and the air pump 8 inflates the first airbag 10 through the two delivery pipes 9 at the output end. Since the first airbag 10 and the second airbag 12 are interconnected through the connecting pipe 11, the gas will fill the first airbag 10 and the second airbag 12. Since the first airbag 10 and the second airbag 12 are connected to the surface of the first protective frame 4 and the second protective frame 7, an inflatable buffer layer is formed around the surveying and mapping camera 3, further enhancing the protection effect. The first airbag 10 and the second airbag 12 protect the surface of the first protective frame 4 and the second protective frame 7, which can effectively buffer the impact force from all directions and reduce the risk of damage to the surveying and mapping camera 3 due to rolling collision;

[0038] The first protective frame 4 and the second protective frame 7 will undergo elastic deformation when a collision occurs, absorbing and dispersing the impact energy, preventing direct rigid collision from being transmitted to the surveying and mapping camera 3, and protecting the precision optical and electronic components inside the camera from damage;

[0039] The support frame 15 is fixed inside the first protective frame 4 and the second protective frame 7. The heat conducting plate 16 inside the support frame 15 is used to conduct the heat generated by the mapping camera 3 when it is working. The heat is transferred to the multiple fins 17 through the heat conducting plate 16. Since the surfaces of the first protective frame 4 and the second protective frame 7 are provided with heat dissipation ports, the fins 17 are arranged inside the heat dissipation ports. Through natural convection or airflow during flight, heat can be dissipated from the fins 17, thereby achieving heat dissipation for the mapping camera 3 and ensuring that the mapping camera 3 works normally within a suitable temperature range.

[0040] The two supporting legs 24 at the bottom of the drone body 1 are used to support the entire drone body 1 when the drone lands. The rubber layer 25 at the bottom of the supporting legs 24 plays a buffering role. When the drone body 1 lands and contacts the ground, the rubber layer 25 can absorb and buffer the impact force at the moment of landing, reduce the impact on the drone as a whole, and prevent damage to internal components caused by the landing impact, especially damage to the mapping camera 3 at the bottom and its protective mechanism.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
