A geographic information mapping drone

Abstract

The present invention discloses a geographic information mapping unmanned aerial vehicle, including a fuselage. A tail rod is fixedly connected to the outer surface of the fuselage, and a tail rotor is fixedly connected to the outer surface of the tail rod. Moving devices are arranged on both sides of the fuselage, and a fixed rod is fixedly connected to the lower surface of the moving device. The present invention relates to the technical field of aircraft. By providing a support device, when the device is in use, as the fuselage descends, the lower surface of the support feet contacts the ground. Since each support device is relatively independent, it can adapt to different ground surfaces. As the ground pressure is transmitted, the angle between the large arm and the small arm decreases, and the pin at the top of the sliding rod slides along the inner surface of the chute, and the telescopic rod contracts. By converting gravitational potential energy into elastic potential energy of the spring inside the telescopic rod, the impact of the ground on the device is reduced.

[0005] However, in the prior art, although the above - mentioned patent has the above - mentioned technical advantages, its disadvantages are that the propeller blades of the device are exposed, and in deeper underground caves and dark rivers, it is very easy to collide and be damaged, affecting the stability of the flying chess and the surveying and mapping accuracy. Moreover, due to ground obstruction, the signal is very difficult to transmit, and it is very difficult for ground operators to perform long - distance remote control. Without satellite coordinate guidance, the drone cannot return in time. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: A geographical information mapping drone, including a fuselage, the outer surface of the fuselage is fixedly connected with a tail rod, the outer surface of the tail rod is fixedly connected with a tail rotor, both sides of the fuselage are provided with moving devices, the lower surface of the moving device is fixedly connected with a fixed rod, the bottom end of the fixed rod is fixedly connected with a rubber ring, the outer surface of the rubber ring is rotatably connected with a supporting device, a bracket is arranged outside the supporting device, and the outer surface of the bracket is rotatably connected with a camera. The moving device drives the fuselage to move up, down, left, right, front and back. During the movement of the fuselage, the camera at the bottom of the bracket takes terrain data for mapping.

During the descent of the fuselage, the fixed rod prevents the supporting device from falling off through the rubber ring, and the supporting device contacts the ground, and the equipment completes the landing. Due to the existence of the circuit board and the partition board, the inner cavity of the fuselage is divided into three areas. Electronic components are installed on the circuit board, and a battery is installed inside the battery compartment to provide power for the equipment.

During the movement and exploration of the fuselage, the pump body sucks the fluorescent ink, then squeezes it into the interior of the connecting pipe, and finally sprays it upward from the nozzle to the external rock wall. When the equipment is mapping inside an underground river or a cave, due to the large depth underground, it is difficult for satellite signals to penetrate, and the positioning system inside the equipment has a large working delay.

[0009] As a preferred implementation, the inner surface of the fuselage is fixedly connected with the outer surface of the partition board, the inner surface of the fuselage is fixedly connected with the lower surface of the pump body, the upper surface of the pump body is fixedly connected with the lower surface of the circuit board, the outer surface of the nozzle is fixedly connected with the inner surface of the fuselage, and the light-emitting lamp beads are arranged in a circular pattern along the upper surface of the photosensitive plate. When the equipment is deeply mapping, it sprays fluorescent ink onto the top rock wall every thirty seconds. During the return flight of the equipment, the light-emitting lamp beads emit light upward, and the light is reflected by the fluorescence of the ink and received downward by the photosensitive plate. Through the induction of the fluorescence by the spectrometer, the equipment realizes automatic return flight.

According to Bernoulli's principle, the pressure is low where the flow rate is high. Under the push of the air pressure difference, the limiting pin slides downward along the inner wall of the housing, the compression spring is compressed, the sealing ring moves away from the air inlet hole, the pressing plate presses the top of the spacer, and the outside air enters the inside of the housing through the air inlet hole. Before this, the intercepting strip preliminarily intercepts the flocs.

As the air flow enters, the air flows from the gap of the spacer to the bottom of the propeller, and the reaction force forces the device to move. The downward pressing pressing plate forces the top of the spacer to approach the motor, the distance between the spacers decreases, the air pressure increases, a large air pressure is provided by a small air flow, the moving speed of the device is increased, and the remaining impurities in the air flow can be taken out from the sewage discharge groove, improving the protection outside the propeller and preventing internal blockage.

[0014] As a preferred embodiment, the support device includes a boom. The lower surface of the boom is rotatably connected to a forearm.

The outer surface of the pin is fixedly connected to a telescopic rod. The outer surface of the pin is slidably connected to a chute. The chute is formed in the wall of the boom. The bottom end of the forearm is rotatably connected to a support foot. As the body descends, the lower surface of the support foot contacts the ground. Since each support device is relatively independent, it can adapt to different ground surfaces. As the ground pressure is transmitted, the angle between the boom and the forearm decreases.

The top end of the telescopic rod is rotatably connected to the outer surface of the body. The pin at the top end of the sliding rod slides along the inner surface of the chute. The telescopic rod contracts, converting gravitational potential energy into elastic potential energy of the spring inside the telescopic rod to reduce the impact of the ground on the device.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By providing the body in the present invention, when the device is in use, the moving device drives the body to move up, down, left, right, forward and backward. During the movement of the body, the camera at the bottom of the bracket takes terrain data for mapping. The tail rotor outside the tail rod not only counterweights the body but also prevents the body from tipping over during high-speed movement, improving stability. During the descent of the body, the fixed rod passes through the rubber ring to prevent the support device from falling off. The support device contacts the ground and the device completes the landing. Due to the presence of the circuit board and the partition, the inner cavity of the body is divided into three areas. Electronic components are installed on the circuit board. A battery is installed inside the battery compartment to provide power for the device. The fluorescent ink tank is filled with fluorescent ink. During the exploration movement of the body, the pump sucks in the fluorescent ink, then squeezes it into the connecting pipe, and finally sprays it upward from the nozzle to the external rock wall. When the device is conducting surveys inside underground rivers or caves, since the underground depth is relatively large and satellite signals are difficult to penetrate, the positioning system inside the device has a large working delay. When the device is deeply surveying, fluorescent ink is sprayed onto the top rock wall every thirty seconds. During the return journey of the device, the light-emitting beads emit light upward. The light is reflected by the fluorescent ink and received downward by the photosensitive plate. Through the induction of the fluorescence by the spectrometer, the device realizes automatic return. When subsequent personnel enter, they can also shine a flashlight and explore and survey according to the guidance of the fluorescent ink. Moreover, since the body adopts a hollow spherical sealed structure, the relatively heavy ink and battery are installed at the bottom of the body. Using the principle of a tumbler, the body can automatically right itself. The sealed sphere can also prevent the device from sinking after falling into water.

[0018] 2. The present invention controls the movement of the device by setting a moving device. When the device is in use, the rotating shaft inside the side rod rotates driven by a motor, and the direction of the propeller is controlled by adjusting the outer ring, thereby achieving the control of the device's movement. The motor drives the propeller to rotate, increasing the airflow inside the housing. According to Bernoulli's principle, the pressure is low where the flow rate is high. Under the push of the air pressure difference, the limit pin slides downward along the inner wall of the housing, compressing the spring and squeezing the sealing ring away from the air inlet hole. The pressing plate squeezes the top of the spacer plate, and the outside air enters the inside of the housing through the air inlet hole. Before this, the intercepting strip preliminarily intercepts the flocs. As the airflow enters, the air flows from the gap of the spacer plate to the bottom of the propeller, and the reaction force forces the device to move. The pressing-down pressing plate forces the top of the spacer plate to approach the motor, reducing the distance between the spacer plates and increasing the air pressure. A larger air pressure is provided by a smaller airflow to accelerate the movement speed of the device. The remaining impurities in the airflow can be taken out from the sewage tank, improving the protection outside the propeller and preventing internal blockage.

[0019] 3. The present invention controls the movement of the device by setting a moving device. When the device is in use, as the body descends, the lower surface of the support foot contacts the ground. Since each support device is relatively independent and can adapt to different ground conditions, as the ground pressure is transmitted, the angle between the large arm and the small arm decreases, and the pin at the top of the sliding rod slides along the inner surface of the chute, and the telescopic rod contracts. By converting the gravitational potential energy into the elastic potential energy of the spring inside the telescopic rod, the impact of the ground on the device is reduced.

The inner surface of the fuselage 1 is fixedly connected to the outer surface of the partition 11, the inner surface of the fuselage 1 is fixedly connected to the lower surface of the pump body 14, the upper surface of the pump body 14 is fixedly connected to the lower surface of the circuit board 10, the outer surface of the nozzle 16 is fixedly connected to the inner surface of the fuselage 1, and the light-emitting lamp beads 18 are arranged in a circular pattern along the upper surface of the photosensitive plate 17.

[0031] The mobile device 4 drives the body 1 to move up and down, left and right, forward and backward. During the movement of the body 1, the camera 7 at the bottom of the bracket 6 takes topographic data for mapping. The tail rotor 3 outside the tail rod 2 acts as a counterweight for the body 1 and prevents the body 1 from tipping over during high-speed movement, improving stability. During the descent of the body 1, the fixing rod 9 prevents the support device 5 from falling off through the rubber ring 8. The support device 5 contacts the ground, and the equipment completes the landing. Due to the presence of the circuit board 10 and the partition 11, the inner cavity of the body 1 is divided into three areas. Electronic components are installed on the circuit board 10, and a battery is installed inside the battery compartment 12 to provide power for the equipment. The fluorescent ink tank 13 is filled with fluorescent ink. During the exploration movement of the body 1, the pump body 14 sucks in the fluorescent ink, then squeezes it into the inside of the connecting pipe 15, and finally sprays it upward from the nozzle 16 to the external rock wall. When the equipment is conducting surveys inside underground rivers or caves, due to the large depth underground, satellite signals are difficult to penetrate, and the positioning system inside the equipment has a large working delay. When the equipment conducts in-depth surveys, it sprays fluorescent ink onto the top rock wall every thirty seconds. During the return journey of the equipment, the light-emitting lamp beads 18 emit light upward. The light is reflected by the ink fluorescence and received downward by the photosensitive plate 17. Through the induction of the fluorescence by the spectrometer, the equipment realizes automatic return. When subsequent personnel enter, they can also shine a flashlight and explore and survey according to the guidance of the fluorescent ink. Moreover, since the body 1 adopts a hollow spherical sealing structure, the heavier ink and battery are installed at the bottom of the body 1. Using the principle of a tumbler, the body 1 can automatically right itself. The sealed sphere can also prevent the equipment from sinking after falling into the water.

[0032] The mobile device 4 includes a side rod 20. The inner surface of the side rod 20 is rotatably connected to a rotating shaft 21. The top end of the rotating shaft 21 is fixedly connected to an outer ring 22. The upper surface of the outer ring 22 is fixedly connected to a housing 23. A sewage discharge groove 24 is opened in the wall of the housing 23. An air inlet hole 25 is provided at the top of the sewage discharge groove 24. An intercepting strip 26 is provided outside the air inlet hole 25. The outer surface of the side rod 20 is fixedly connected to the outer surface of the body 1. The lower surface of the side rod 20 is fixedly connected to the top end of the fixing rod 9. The air inlet hole 25 is opened in the wall of the housing 23. The outer surface of the housing 23 is fixedly connected to the outer surface of the intercepting strip 26. The air inlet hole 25 and the sewage discharge groove 24 are arranged annularly along the inner wall of the housing 23. The inner surface of the outer ring 22 is rotatably connected to a propeller 30. The outer surface of the propeller 30 is rotatably connected to a motor 31. A spacer 32 is provided outside the motor 31. A pressing plate 33 is provided outside the spacer 32. The outer surface of the pressing plate 33 is fixedly connected to a sealing ring 34. A limiting pin 35 is provided at the top of the sealing ring 34. The outer surface of the limiting pin 35 is fixedly connected to a compression spring 36.

[0033] The rotating shaft 21 inside the side lever 20 is driven by a motor to rotate. By adjusting the outer ring 22, the wind direction of the propeller 30 is controlled, thereby realizing the control of the movement of the device. The motor 31 drives the propeller 30 to rotate, increasing the air flow inside the housing 23. According to Bernoulli's principle, where the flow velocity is large, the pressure is small. Under the push of the air pressure difference, the limit pin 35 slides downward along the inner wall of the housing 23, compressing the spring 36 and squeezing, the sealing ring 34 moves away from the air inlet hole 25, the pressing plate 33 squeezes the top of the spacer plate 32, and the outside air enters the inside of the housing 23 from the air inlet hole 25. Before this, the intercepting strip 26 preliminarily intercepts the flocculent substances. As the air flow enters, the air flows through the gaps of the spacer plate 32 to the bottom of the propeller 30, and the reaction force forces the device to move. The downward pressing plate 33 forces the top of the spacer plate 32 to approach the motor 31, the distance between the spacer plates 32 decreases, the air pressure increases, a larger air pressure is provided by a smaller air flow, the moving speed of the device is accelerated, and the remaining impurities in the air flow can be taken out from the sewage discharge groove 24, improving the protection outside the propeller 30 and preventing internal blockage.

[0034] The lower surface of the motor 31 is fixedly connected to the outer surface of the outer ring 22. The lower surface of the spacer plate 32 is fixedly connected to the upper surface of the outer ring 22. The spacer plate 32 is located inside the housing 23. The inner surface of the housing 23 is slidably connected to the outer surface of the limit pin 35. The upper surface of the housing 23 is fixedly connected to the bottom end of the compression spring 36. The inner surface of the bottom of the pressing plate 33 is in contact with the outer surface of the top of the spacer plate 32. The supporting device 5 includes a large arm 40. The lower surface of the large arm 40 is rotatably connected to a small arm 41. The outer surface of the small arm 41 is rotatably connected to a sliding rod 43. The top end of the sliding rod 43 is fixedly connected to a plug pin 44. The outer surface of the plug pin 44 is fixedly connected to a telescopic rod 46. The outer surface of the plug pin 44 is slidably connected to a chute 45. The chute 45 is opened in the wall of the large arm 40. The bottom end of the small arm 41 is rotatably connected to a supporting foot 42. The top end of the large arm 40 is rotatably connected to the lower surface of the rubber ring 8. The top end of the telescopic rod 46 is rotatably connected to the outer surface of the machine body 1.

[0035] As the machine body 1 descends, the lower surface of the supporting foot 42 contacts the ground. Since each supporting device 5 is relatively independent and can adapt to different grounds, as the ground pressure is transmitted, the included angle between the large arm 40 and the small arm 41 decreases, the plug pin 44 at the top end of the sliding rod 43 slides along the inner surface of the chute 45, and the telescopic rod 46 contracts, converting the gravitational potential energy into the elastic potential energy of the spring inside the telescopic rod 46 to reduce the impact of the ground on the device.

[0036] Working principle:

[0037] When the device is in use, the mobile device 4 drives the body 1 to move up and down, left and right, forward and backward. During the movement of the body 1, the camera 7 at the bottom of the bracket 6 takes pictures and draws topographic data. The tail rotor 3 outside the tail rod 2 acts as a counterweight for the body 1 while preventing the body 1 from tipping over during high-speed movement, improving stability. During the descent of the body 1, the fixed rod 9 prevents the support device 5 from falling off through the rubber ring 8. The support device 5 contacts the ground, and the device completes the landing. Due to the presence of the circuit board 10 and the partition 11, the inner cavity of the body 1 is divided into three areas. Electronic components are installed on the circuit board 10, and a battery is installed inside the battery compartment 12 to provide power for the device. The fluorescent ink tank 13 is filled with fluorescent ink. During the exploration movement of the body 1, the pump body 14 sucks in the fluorescent ink and then squeezes it into the connecting pipe 15, and finally sprays it upward from the nozzle 16 to the outside rock wall. When the device is conducting surveys in underground rivers or caves, due to the large depth underground, satellite signals are difficult to penetrate, and the positioning system inside the device has a large working delay. When the device conducts in-depth surveys, it sprays fluorescent ink on the top rock wall every thirty seconds. During the return journey of the device, the light-emitting lamp beads 18 emit light upward. The light is reflected by the fluorescent ink and then received downward by the photosensitive plate 17. Through the induction of the fluorescence by the spectrometer, the device realizes automatic return. When subsequent personnel enter, they can also shine a flashlight and explore and survey according to the guidance of the fluorescent ink. Moreover, since the body 1 adopts a hollow spherical sealed structure, the relatively heavy ink and battery are installed at the bottom of the body 1. Using the principle of a tumbler, the body 1 can automatically right itself. The sealed sphere can also prevent the device from sinking after falling into the water.

[0038] The rotating shaft 21 inside the side rod 20 rotates driven by an electric motor. By adjusting the outer ring 22, the wind direction of the propeller 30 is controlled, thereby realizing the control of the device's movement. The motor 31 drives the propeller 30 to rotate, and the air flow inside the housing 23 increases. According to Bernoulli's principle, the pressure is low where the flow rate is high. Under the push of the air pressure difference, the limit pin 35 slides downward along the inner wall of the housing 23, compressing the spring 36 and squeezing the sealing ring 34 away from the air inlet 25. The pressing plate 33 presses the top of the spacer 32, and outside air enters the inside of the housing 23 from the air inlet 25. Before this, the intercepting strip 26 preliminarily intercepts the flocs. As the air flow enters, the air flows from the gap of the spacer 32 to the bottom of the propeller 30, and the reaction force forces the device to move. The pressing plate 33 pressing down forces the top of the spacer 32 to approach the motor 31, and the distance between the spacers 32 decreases, increasing the air pressure. A large air pressure is provided by a small air flow to accelerate the movement speed of the device. The remaining impurities in the air flow can be taken out from the sewage groove 24, improving the protection outside the propeller 30 and preventing internal blockage.

[0039] As the body 1 descends, the lower surface of the support leg 42 contacts the ground. Since each support device 5 is relatively independent and can adapt to different ground surfaces, as the ground pressure is transmitted, the angle between the boom 40 and the forearm 41 decreases, and the pin 44 at the top of the sliding rod 43 slides along the inner surface of the chute 45, and the telescopic rod 46 contracts. By converting the gravitational potential energy into the elastic potential energy of the spring inside the telescopic rod 46, the impact of the ground on the device is reduced.

[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the scope of protection of the present invention.
