Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle equipment, and in particular to a surveying and mapping unmanned aerial vehicle with a protective function. Background Art

[0002] With the development of science and technology, surveying and mapping drones have become one of the iconic tools of the surveying and mapping industry in the new era. Due to their high precision, speed, safety and reliability, surveying and mapping drones have been widely used in various complex geographical environment surveying and mapping tasks, from mountains and hills to urban buildings, from forests and wetlands to rivers and oceans, drones are everywhere.

[0003] Nowadays, when surveying and mapping drones are used, they usually operate outdoors at high altitudes. Taking advantage of the high altitude, surveying and mapping drones can easily carry out surveying and mapping work. In order to map more accurate and clearer pictures, existing surveying and mapping drones are generally equipped with high-precision cameras, lidars and other equipment to obtain high-quality spatial data. Therefore, once a surveying and mapping drone loses control and falls in the air, its collision with the ground will not only easily cause damage to the equipment on the surveying and mapping drone, but also easily lead to the loss of surveying and mapping data. Although existing surveying and mapping drones are often equipped with parachutes for protection, parachutes can only protect by reducing the speed of the surveying and mapping drone's fall. Therefore, when the surveying and mapping drone touches the ground, it will still cause damage to the precision equipment on the surveying and mapping drone, and it is even easy to sink to the bottom of the water when it falls into the water, causing greater losses.

[0033] See also Figure 5 and Figure 6 As shown, the inflation mechanism I includes a gas tank I10, a valve I11, a fixed pipe 12 and an air supply pipe I13; the two gas tanks I10 are detachably installed on the front and rear sides of the temporal part of the drone body 1; the two valves I11 are respectively connected to the front and rear sides of the inside of the drone body 1, and the air inlet of the valve I11 is connected to the air outlet of the gas tank I10; the front and rear sides of the top and the front and rear sides of the bottom of the drone body 1 are connected to the fixed pipe 12, and the two fixed pipes 12 on the front side are connected to the air outlet of the valve I11 on the front side, and the two fixed pipes 12 on the rear side are connected to the air outlet of the valve I11 on the rear side; the two ends of the air supply pipe I13 are respectively rotatably connected to the fixed pipe 12 and the rotating pipe 6, so that the air in the gas tank I10 can be filled into the rotating pipe 6 through the valve I11, the fixed pipe 12 and the air supply pipe I13.

[0034] See also Figure 5 and Figure 6 As shown, the rotating mechanism includes a rack I14, a gear I15 and a micro right-angle gearbox 16; the left and right sides of the fixed tube 12 are slidably connected with the rack I14; the rotating tube 6 is connected with the gear I15, and the gear I15 is meshed with the rack I14, and the rack I14 blocks the air inlet of the air supply pipe I13, so that after the air enters the fixed tube 12, the air in the fixed tube 12 will first squeeze the rack I14 to move, so that the rack I14 can drive the gear I15 to rotate by moving, thereby driving the rotating tube 6 to rotate; eight micro right-angle gearboxes 16 are all connected to the drone body 1, and the output ends of the eight micro right-angle gearboxes 16 are respectively connected to the eight rotating rods 8, so that people can twist the input end of the micro right-angle gearbox 16 to rotate, and the micro right-angle gearbox 16 can drive the rotating rod 8 to rotate.

[0035] See also Figure 7 As shown, the inflation mechanism II includes a gas tank II 17, a valve II 18 and an air pipe II 19; the gas tank II 17 is detachably mounted at the bottom of the UAV body 1; two valves II 18 are respectively connected to the left and right sides of the bottom of the UAV body 1, and the air inlets of the two valves II 18 are respectively connected to the air outlets on the left and right sides of the gas tank II 17; the two ends of the air pipe II 19 are respectively connected to the air outlet of the valve II 18 and the air bag I 4, so that the air in the gas tank II 17 can be filled into the air bags I 4 and II 5 through the valve II 18 and the air pipe II 19.

[0036] When in use, the drone body 1 can be lifted off by the high-speed rotation of the propeller, and then the drone body 1 can be remotely controlled to fly in the air, and the high-precision camera of the mapping component 3 can be used to rotate and take pictures for mapping. When the drone body 1 loses control and falls in the air, the sensor on the drone body 1 will sense that the body is falling at a high speed, and then the drone body 1 will automatically control the parachute of the parachute component 2 to open, so that the parachute will reduce the falling speed of the drone body 1 after opening. At the same time, the drone body 1 will automatically control the valve Ⅰ11 and the valve Ⅱ18 to open, so that the compressed gas in the gas tank Ⅰ10 enters the valve Ⅰ11 and the fixed pipe 12, so that the air in the fixed pipe 12 squeezes the rack Ⅰ14 to the side away from each other. The rack Ⅰ14 moves, thereby driving the gear Ⅰ15 to rotate, thereby driving the rotating tube 6 and the connecting tube 7 to rotate, and then the connecting tube 7 pulls the airbag Ⅲ9 to expand, so that the airbag Ⅲ9 blocks the propeller of the drone body 1. After the air in the fixed tube 12 squeezes the rack Ⅰ14 to move to the point where it does not block the air inlet of the air supply pipe Ⅰ13, the air in the fixed tube 12 enters the rotating tube 6, the connecting tube 7 and the airbag Ⅲ9 through the air supply pipe Ⅰ13, so that the airbag Ⅲ9 expands, and then the airbag Ⅲ9 wraps the propeller of the drone body 1 through expansion, so that when the drone body 1 collides with the ground, the propeller of the drone body 1 can be wrapped by the airbag Ⅲ9 to slow down the vibration of the propeller, thereby At the same time, the air in the gas tank Ⅱ17 will enter the airbag Ⅰ4 and the airbag Ⅱ5 through the valve Ⅱ18 and the air supply pipe Ⅱ19, so that the airbag Ⅰ4 and the airbag Ⅱ5 will expand, so that after the airbag Ⅰ4 expands, it can wrap the side of the drone body 1, so that when the drone body 1 collides with the ground, the airbag Ⅰ4 wraps the side of the drone body 1, which can protect the drone body 1 and prevent the side of the drone body 1 and the surveying and mapping component 3 from directly colliding with the ground, and the airbag Ⅱ5 can expand to wrap the top of the drone body 1, so that when the drone body 1 collides with the ground, the airbag Ⅱ5 wraps the top of the drone body 1, which can prevent the top of the drone body 1 from directly colliding with the ground, and the airbag Ⅰ The expansion of airbags Ⅰ4 and Ⅱ5 can make the drone body 1 float on the water surface through airbags Ⅰ4 and Ⅱ5 after falling into the water, so as to prevent the drone body 1 from sinking directly to the bottom of the water, which is convenient for people to find later. After the drone body 1 that has fallen to the ground or the water surface is found, the deflation valves on airbags Ⅰ4 and Ⅲ9 are opened to deflate airbags Ⅰ4, Ⅱ5 and Ⅲ9, and then the gas tanks Ⅰ10 and Ⅱ17 in the drone body 1 are removed, and then the rack Ⅰ14 is pushed to move to the side close to each other and reset, so that the rack Ⅰ14 blocks the air inlet of the air pipe Ⅰ13 again, and the rack Ⅰ14 drives the gear Ⅰ15 to reverse and reset, thereby driving the rotating tube 6 and the connecting tube 7 to reverse, and then the connecting tube 7 drives the airbag Ⅲ9 to be retracted.Then twist the input end of the micro right angle gearbox 16 to rotate, so that the micro right angle gearbox 16 drives the rotating rod 8 to rotate, so that the rotating rod 8 reels the airbag III9 to prevent the airbag III9 from affecting the propeller of the drone body 1. Then close the valve I11 and valve II18, replace the gas tank I10 and gas tank II17 and reinstall them, then repair and replace the parachute assembly 2, and then the drone body 1 can be used again.

[0037] See also Figure 7 and Figure 8 As shown, a tightening mechanism is also included, which includes a rubber fixing belt 20 and a clamping rod 21; one end of several rubber fixing belts 20 are connected to the drone body 1; several clamping rods 21 are connected to the drone body 1, and the other ends of the rubber fixing belts 20 are clamped on the clamping rods 21, so that the clamping rods 21 can limit the rubber fixing belts 20, and through the rubber fixing belts 20 contacting with airbags I4 and II5, the rubber fixing belts 20 can tighten the airbags I4 and II5.

[0038] When airbags I4 and II5 are inflated, airbags I4 and II5 will squeeze the other end of the rubber fixing belt 20 to detach it from the clamping rod 21, thereby loosening the other end of the rubber fixing belt 20 from the clamping rod 21, and then the rubber fixing belt 20 no longer tightens the airbags I4 and II5; when airbags I4 and II5 are deflated, the other end of the rubber fixing belt 20 can be clamped back onto the clamping rod 21, so that the clamping rod 21 limits the rubber fixing belt 20, thereby tightening the rubber fixing belt 20 to the airbags I4 and II5.

[0039] See also Figure 7 and Fig. 9 As shown, a shielding mechanism is also included, which includes a fixed frame 22, a rotating frame 23 and a driving component; the fixed frame 22 is connected to the bottom of the drone body 1, and the fixed frame 22 is located on the outside of the surveying and mapping component 3; the rotating frame 23 is rotatably connected to the fixed frame 22; the driving component includes a servo motor 24 and a connecting rod 25, the servo motor 24 is connected to the fixed frame 22, the connecting rod 25 is connected to the output shaft of the servo motor 24, and the connecting rod 25 is connected to the rotating frame 23, so that the servo motor 24 can drive the rotating frame 23 to rotate synchronously by driving the connecting rod 25 to rotate, so that the rotating frame 23 can shield the surveying and mapping component 3 through rotation.

[0040] When the drone body 1 automatically controls valve I11 and valve II18 to open, the drone body 1 will simultaneously control the servo motor 24 to drive the connecting rod 25 to rotate, so that the connecting rod 25 drives the rotating frame 23 to rotate, so that the rotating frame 23 blocks the surveying and mapping component 3 in the fixed frame 22, and then the rotating frame 23 and the fixed frame 22 shield and protect the surveying and mapping component 3 to prevent the surveying and mapping component 3 from colliding with foreign objects and causing damage; after the drone body 1 that has fallen to the ground or water surface is found back, the servo motor 24 drives the connecting rod 25 to reverse and reset, so that the connecting rod 25 drives the rotating frame 23 to reverse and reset.

[0041] See also Figure 8 As shown, a synchronization mechanism is also included, which includes a rack II 26 and a gear II 27; the rack II 26 is connected to the rack I 14; the gear II 27 is rotatably connected to the drone body 1, and the rack II 26 is meshed with the gear II 27.

[0042] By setting the rack II 26 and the gear II 27, when the rack I 14 on one side moves, the rack I 14 on one side will drive the gear II 27 to rotate, so that the gear II 27 drives the rack I 14 on the other side to move synchronously. In this way, the racks I 14 on the left and right sides can move synchronously to prevent the air in the fixed pipe 12 from squeezing the rack I 14 on one side to move.

[0043] See also Fig.10 As shown, a buffer mechanism is also included, which includes a buffer rod 28 and an elastic member 29; the two buffer rods 28 are rotatably connected to the left and right sides of the lower part of the drone body 1; the two ends of the elastic member 29 are respectively connected to the buffer rod 28 and the drone body 1, and the elastic member 29 is a torsion spring.

[0044] By providing the buffer rod 28 and the elastic member 29, when the bottom of the drone body 1 contacts the ground, the ground first squeezes the buffer rod 28 to rotate, thereby deforming the elastic member 29. Under the elastic force of the elastic member 29, the impact force of the ground on the buffer rod 28 can be reduced, thereby buffering the drone body 1 and preventing the bottom of the drone body 1 from violently hitting the ground and causing damage.
