Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to an aerial remote sensing mapping device. Background Art

[0002] Surveying and mapping literally means measuring and drawing. It 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 positions reflecting the current situation of the ground and related information through measurement methods for the purpose of engineering construction, planning and design, and administrative management. Aerial remote sensing and mapping equipment is a key component in realizing aerial remote sensing and mapping technology. They capture the electromagnetic wave signals of surface objects and convert them into electrical signals, and then reveal the properties, status and changes of surface objects through data processing and analysis. Aerial remote sensing and mapping equipment is a remote sensing equipment based on medium-, low-altitude or high-altitude remote sensing platforms such as drones for photographic (or scanning) imaging. It mainly includes high-resolution cameras, lidar, infrared scanners and other sensors. This remote sensing drone equipped with a photographic (or scanning) imaging device can be called an aerial remote sensing and mapping equipment.

[0003] However, in order to ensure the accuracy of shooting, some existing drone-type aerial remote sensing mapping equipment will install a self-cleaning mechanism on the mapping lens of this equipment to ensure the clarity of the captured image. However, the self-cleaning mechanism installed on this aerial remote sensing mapping equipment needs to be driven by a power source. This additional power source not only reduces the operating time of the equipment, but also increases the operating cost of the equipment. Moreover, if sudden bad weather is encountered during mapping operations using aerial remote sensing mapping equipment, if this equipment has flown a long distance, then if it flies directly back to the starting point, this equipment may crash due to weather conditions such as strong winds, heavy rains or lightning.

[0020] The wind-driven mechanism includes a small windmill 6, the axis of which is connected to a windmill shaft 7, both ends of which are sleeved with a mounting bracket, and the upper end surface of the mounting bracket is fixed to the surveying and mapping camera 4; when the remote sensing UAV 1 is flying in the outside world, if the surveying and mapping lens 5 is contaminated with foreign matter, the cleaning cotton mounting bracket 19 and the strip cleaning cotton 20 are rotated by the electric rotating shaft 18, so that the strip cleaning cotton 20 is attached to the outer surface of the surveying and mapping lens 5; The wind force generated by the remote sensing UAV 1 during flight can drive the small windmill 6 located below the surveying and mapping camera 4 and the windmill shaft 7 connected to the axis of the small windmill 6 to rotate.

[0021] A first bevel gear 8 is provided on a fixed sleeve on one side of the outer surface of the windmill shaft 7, and the first bevel gear 8 is meshed with a second bevel gear 9, and the axis of the second bevel gear 9 is connected to a first gear transmission shaft 10, and a third bevel gear 11 is provided on the upper side of the outer surface of the first gear transmission shaft 10; the third bevel gear 11 is meshed with a fourth bevel gear 12, and the axis of the fourth bevel gear 12 is connected to a second gear transmission shaft 13, and a gear 14 is provided on a fixed sleeve on one side of the outer surface of the second gear transmission shaft 13, and the gear 14 is meshed with an inner gear ring 1 5, a metal sleeve 16 connected to the surveying and mapping camera 4 through a roller bearing is fixedly arranged on the outer side of the inner gear ring 15, and the surface of the L-shaped mounting bracket 17 facing the metal sleeve 16 is fixed to the metal sleeve 16; the rotating windmill shaft 7 can drive the first bevel gear 8 fixedly sleeved on the outer surface of the windmill shaft 7 and the second bevel gear 9 meshing with the first bevel gear 8 to rotate together, and the rotating second bevel gear 9 can drive the first gear transmission shaft 10 connected to the axis of the second bevel gear 9 and the first gear transmission shaft 10 fixedly sleeved on the first gear transmission shaft 10 0The third bevel gear 11 on the upper side of the outer surface rotates.

The rotating second gear transmission shaft 13 can drive the gear 14 fixedly sleeved on the outer surface of the second gear transmission shaft 13 to rotate. When the gear 14 rotates, the inner gear ring 15 meshing therewith and the metal sleeve 16 fixed to the inner gear ring 15 will rotate together. When the metal sleeve 16 rotates, the metal sleeve 16 fixed to the metal sleeve 16 is rotated. The L-shaped mounting bracket 17 on the lower end surface of the sleeve 16 and the strip cleaning cotton 20 connected to the L-shaped mounting bracket 17 through the electric rotating shaft 18 and the cleaning cotton mounting bracket 19 will revolve around the center point of the front end surface of the surveying and mapping lens 5, and the outer surface of the surveying and mapping lens 5 can be cleaned by the revolving strip cleaning cotton 20. When the cleaning operation of the surveying and mapping lens 5 is completed, the strip cleaning cotton 20 is removed from the outer surface of the surveying and mapping lens 5 by the electric rotating shaft 18, so as to avoid the strip cleaning cotton 20 blocking the sight of the surveying and mapping lens 5; The above technical solution does not require the installation of an additional power source to drive the strip cleaning cotton 20 for cleaning operations. While reducing the overall production cost of the equipment, it also reduces the energy loss during the operation of the remote sensing drone 1 and increases the continuous working time of the remote sensing drone 1.

[0022] A bad weather fixing protection mechanism 2 is fixedly installed on both sides of the lower end surface of the remote sensing UAV 1. The bad weather fixing protection mechanism 2 includes a fixed threaded rod 212, a drill bit 214, two arc-shaped pointed claws 207, two arc-shaped grooves 208 and a synchronous driving mechanism. The drill bit 214 is fixed to the lower end surface of the fixed threaded rod 212; The two arc-shaped pointed claws 207 are respectively located inside the two arc-shaped grooves 208. The synchronous driving mechanism can push the arc-shaped pointed claws 207 to move up and down inside the arc-shaped groove 208 while driving the fixed threaded rod 212 and the drill bit 214 to rotate and move up and down.

[0023] The synchronous drive mechanism includes a metal housing 201, and the distance between the lower end surface of the arc-shaped pointed claw 207 and the lower end surface of the metal housing 201 is shorter than the distance between the lower end surface of the drill bit 214 and the lower end surface of the metal housing 201; A stepper motor 202 is fixedly installed on the upper side of the metal shell 201, and the output shaft of the stepper motor 202 is connected to a square shaft 203 through a coupling. A circular lifting plate 204 fixed to the upper end face of the fixed threaded rod 212 is provided on the outer side of the square shaft 203, and a square slot 213 is provided in the middle position of the upper end face of the circular lifting plate 204 to enter the fixed threaded rod 212, and the square shaft 203 is inserted into the square slot 213; when the remote sensing UAV 1 is performing surveying and mapping operations in the outside world, if it encounters sudden bad weather, it will first park itself directly on the muddy ground of the surveying and mapping location, and then start the stepper motor 202, so that the stepper motor 202 can drive the square shaft 203 connected thereto to rotate.

[0024] The inner wall cross-section of the square slot 213 is square, the outer surface of the square shaft 203 fits with the inner wall of the square slot 213, and the square shaft 203 and the square slot 213 are slidably connected; the outer side of the bottom end of the fixed threaded rod 212 is provided with an internal thread groove 215 located in the middle position of the lower end surface of the metal shell 201, and the external thread of the fixed threaded rod 212 matches the internal thread of the internal thread groove 215; since the outer surface of the square shaft 203 fits with the inner wall of the square slot 213, when the square shaft 203 rotates, the circular lifting plate 204 and the fixed threaded rod 212 will rotate together, and under the drive of the internal thread structure of the internal thread groove 215, the rotating fixed threaded rod 212 and the circular lifting plate 204 will rotate and move up and down accordingly, and at this time, the fixed threaded rod 212 and the circular lifting plate 204 are driven to rotate and move downward.

[0025] A roller bearing ring 205 is installed at the middle position of the outer surface of the circular lifting plate 204 through a roller bearing, and a metal rod 209 is fixedly installed on both sides of the lower end surface of the roller bearing ring 205. A spring 210 is sleeved on the outer surface of the metal rod 209, and the lower end surfaces of the two springs 210 are connected to a lower pressure ring 206 that is movably sleeved on the outer surfaces of the two metal rods 209 at the same time. A metal sleeve 211 is connected to both sides of the lower end surface of the lower pressure ring 206, and the two metal sleeves 211 are movably sleeved on the outer surfaces of the two metal rods 209 respectively; during the up and down movement of the circular lifting plate 204, the roller bearing ring 205 installed on the outer surface of the circular lifting plate 204 and the lower pressure ring 206 connected to the roller bearing ring 205 through the metal rod 209, the spring 210 and the metal sleeve 211 will move up and down together. As the circular lifting plate 204 descends, the The lower pressure ring 206 and the arc-shaped pointed claw 207 connected to the lower end surface of the lower pressure ring 206 will move downward together with it. Guided by the arc-shaped groove 208, the arc-shaped pointed claw 207 moving downward will move in an arc shape. Since the distance between the lower end surface of the arc-shaped pointed claw 207 and the lower end surface of the metal shell 201 is shorter than the distance between the lower end surface of the drill bit 214 and the lower end surface of the metal shell 201, the arc-shaped pointed claw 207 moving in an arc shape will be inserted into the mud ground before the drill bit 214, so as to preliminarily fix the lower end surface of the metal shell 201 and the mud ground. By inserting the arc-shaped pointed claw 207 into the mud ground first, it can be prevented that the drill bit 214 moving downward while rotating cannot drill into the mud ground immediately due to the overall light weight of the equipment or the hard soil of the mud ground, thereby preventing the overall overturning of the equipment; After the arc-shaped pointed claw 207 is inserted into the muddy ground, the drill bit 214 that rotates and moves downward will also contact the muddy ground and drill into the inside of the muddy ground. As the drill bit 214 goes deeper, the fixed threaded rod 212 fixed to the upper end surface of the drill bit 214 will also enter the inside of the muddy ground. The drill bit 214 and the fixed threaded rod 212 that drill into the inside of the muddy ground can stably fix the entire device on the muddy ground. If the duration of the bad weather is short, the remote sensing drone 1 is directly parked at the current position, and after the bad weather is over, the square rotating shaft 203 connected to it is driven by the stepper motor 202 to rotate in the opposite direction, so as to synchronously move the arc-shaped pointed claw 207, the fixed threaded rod 212 and the drill bit 214 upward to release the fixation between the device and the muddy ground, and then continue the surveying and mapping operation. If the duration of the bad weather is long, a special recovery personnel will be sent to recover the equipment. Improve the above technical solution. Under severe weather conditions, the equipment can be automatically fixed to the ground, avoiding unstable flight and potential crash risks caused by weather, thereby improving the safety of the equipment. By fixing the remote sensing UAV 1, it is possible to prevent the remote sensing UAV 1 from being forced to be blown up by strong winds from the outside and colliding with external objects. For the remote sensing UAV 1 that needs to operate under various climatic conditions, the severe weather fixing protection mechanism 2 enables it to quickly adjust its state when encountering sudden weather changes, so that it no longer needs to return to the starting point immediately once it encounters sudden severe weather, thereby maintaining the continuity of operation and enhancing the adaptability of the equipment. By fixing the equipment to the ground, the possibility of loss or damage of the equipment caused by sudden severe weather can be reduced, thereby reducing economic losses and maintenance costs. When the lower end surface of the lower pressure ring 206 has contacted the inside of the metal shell 201 and cannot push the lower pressure ring 206 downward any further, as the roller bearing ring 205 descends, the distance between the lower end surface of the roller bearing ring 205 and the upper end surface of the lower pressure ring 206 will gradually decrease, squeezing the spring 210 used to ensure that the roller bearing ring 205 and the lower pressure ring 206 always maintain a certain distance. This structure can prevent the lower end surface of the lower pressure ring 206 from contacting the inside of the metal shell 201, thereby preventing the fixed threaded rod 212 indirectly connected thereto from being stuck and unable to continue to move downward into the inside of the muddy ground. The above-mentioned synchronous driving mechanism can synchronously drive the arc-shaped pointed claw 207 and the drill bit 214 located in the severe weather fixed protection mechanism 2. Through this driving mechanism, while reducing the production cost of the equipment, when a power failure occurs in the equipment, the location of the fault can be quickly found.

[0026] A guide rod is provided at the front and rear sides of the lower pressure ring 206. A guide sleeve is movably provided on the outer surface of the guide rod, and the surface of the guide sleeve facing the lower pressure ring 206 is fixed to the lower pressure ring 206. The stability of the lower pressure ring 206 moving up and down can be ensured by the guide rod and the guide sleeve.

[0027] A circular cover plate is provided above the stepper motor 202 and is located on the upper end surface of the metal shell 201, and the metal shell 201 and the circular cover plate are fixed by screws; the circular cover plate can protect the stepper motor 202, and when the stepper motor 202 fails, the circular cover plate can be removed for maintenance.

[0028] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
