Description

Technical Field

[0001] This invention relates to the field of surveying and mapping technology, and in particular to a fully automatic topographic mapping device and method. Background Technology

[0002] Surveying and mapping, literally understood as measurement and drawing, is based on computer technology, optoelectronic technology, network communication technology, space science, and information science. It uses Global Navigation Satellite System (GNSS), Remote Sensing (RS), and Geographic Information System (GIS) as its core technologies. It selects existing feature points and boundaries on the ground and obtains graphics and locations reflecting the current state of the ground and related information through measurement methods for use in engineering construction, planning and design, and administrative management.

[0003] In topographic mapping, drones are commonly used to improve efficiency. However, when landing on complex or uneven terrain, the outriggers of most existing mapping drones cannot automatically adjust to the flatness of the ground. This can cause the drone to tip over and damage its wings due to gaps between the outriggers and the ground during landing. Summary of the Invention

[0004] This invention discloses a fully automated topographic mapping device and method, aiming to solve the problem in the background art where drones are commonly used for topographic mapping to improve efficiency. However, existing mapping drones often cannot automatically adjust their support legs according to the flatness of the ground when landing on complex and uneven terrain. This results in gaps between the support legs and the ground, making the drone prone to tipping over and causing wing damage during landing.

[0005] This invention proposes a fully automatic topographic mapping device, comprising a main body and a mapping base. Four fixed legs are externally connected to the mapping base, and one end of each fixed leg is movably connected to an arc-shaped support leg. Mounting components are fixedly connected to the outer walls of each of the four arc-shaped support legs, and auxiliary support rods are movably connected to the interiors of each of the four mounting components. A single torsion spring is fixedly connected to the inner walls of both sides of each of the four mounting components, and the outer walls of the four torsion springs respectively contact the outer walls of the four auxiliary support rods. Mounting holes are formed on one side of the outer wall of each of the four fixed legs, and mounting rods are movably connected to the interiors of each of the four mounting holes. Connecting rods are fixedly connected to both ends of each of the four mounting rods. Two connecting rods on the same mounting rod are fixedly connected to opposite outer walls. There is a common fixed rod, and each of the four arc-shaped support legs has a movable opening on one side of its outer wall. The four fixed rods are located inside the four movable openings. Multiple protrusions are fixedly connected at equal intervals on one side of the inner wall of each of the four movable openings. Elastic members are fixedly connected to the outer walls of the four fixed rods. The outer walls of the four elastic members are in contact with the outer walls of the four protrusions. Each of the four arc-shaped support legs has a reset opening on one side of its outer wall. The four reset openings are connected to the four movable openings. Pressure rods are fixedly connected to the outer walls of each of the four elastic members. The four pressure rods are located inside the four reset openings. Support springs are fixedly connected to the outer walls of each of the four fixed legs. One end of each support spring is fixedly connected to the outer wall of one side of each of the four arc-shaped support legs.

[0006] Equipped with fixed outriggers, arc-shaped support legs, auxiliary support rods, mounting components, connecting rods, elastic elements, protrusions, return springs, torsion springs, and pressure rods, the four arc-shaped support legs can automatically adjust their angles according to the unevenness of the ground during landing. This ensures the drone remains level after landing, preventing it from tipping over and being damaged, thus improving the device's usability. During landing, the torsion springs and auxiliary support rods further enhance support and stability. When the device is retrieved, the torsion springs automatically reset the auxiliary support rods, and pressing the pressure rods separates the elastic elements from the protrusions, allowing the support springs to quickly reset the arc-shaped support legs. The operation is convenient and quick, facilitating subsequent use.

[0007] In a preferred embodiment, four buffer sleeves are fixedly connected to the bottom of the machine body, and buffer rods are movably connected inside each of the four buffer sleeves. The bottom ends of the four buffer rods are fixedly connected to the top of the surveying base, and the top of the surveying base is provided with the surveying equipment body. Four buffer spring rods are fixedly connected to the bottom of the machine body, and the four buffer spring rods are respectively located inside the four buffer sleeves. The bottom ends of the four buffer spring rods are respectively fixedly connected to the top of the four buffer rods.

[0008] By incorporating a buffer sleeve, a buffer rod, and a buffer spring rod, the buffer spring rod absorbs the vibration generated by the buffer rod when it is compressed, thereby reducing the impact of the vibration generated by the rotation of the spiral blade on the surveying base and ensuring the accuracy of topographic mapping.

[0009] In a preferred embodiment, the outer walls of the four buffer sleeves are fixedly connected to the same heat-conducting base plate. The top of the heat-conducting base plate is fixedly connected to the same control power supply to the bottom of the machine body. Multiple heat-conducting fins are fixedly connected to the top of the heat-conducting base plate, and one side of the outer wall of each of the multiple heat-conducting fins is in contact with the outer wall of the control power supply. Through holes are opened on one side of the outer wall of each of the multiple heat-conducting fins. The inner walls of the multiple through holes on the same side are fixedly connected to the same cooling pipe, and the outer walls of the four cooling pipes are equipped with circulation pumps. Multiple heat sinks are fixedly connected to the bottom of the machine body and the top of the heat-conducting base plate. Openings are opened on one side of the outer wall of each of the multiple heat sinks. The outer walls of the four cooling pipes are respectively fixedly connected to the inner walls of the multiple openings.

[0010] By incorporating a heat-conducting base plate, heat-conducting fins, a heat sink, a circulating pump, cooling pipes, and a control power supply, the heat-conducting base plate and fins absorb the heat generated by the control power supply, improving its heat dissipation. Airflow further dissipates heat from the heat-conducting fins and base plate. Multiple heat-conducting fins increase their contact with air during measurement, further enhancing heat dissipation. The circulating pump and cooling pipes cool the heat-conducting fins, enabling them to quickly absorb heat from the control power supply and extending its lifespan. The heat sink rapidly cools the coolant inside the cooling pipes. This cooling effect of the cooling pipes on the heat-conducting fins, combined with the fins' efficient heat absorption, increases the device's practicality.

[0011] In a preferred embodiment, the top of the machine body has four mounting grooves, each containing a drive motor. The output shafts of the four drive motors are connected to helical blades via couplings. A dust collection chamber is located on the top of the machine body. Fixing members are fixedly connected to the outer walls of both sides of the surveying base. The inner walls of the two fixing members are fixedly connected to the same annular tube, and the outer wall of the annular tube has multiple suction ports at equal intervals. Dust pumps are connected to the outer walls of both sides of the dust collection chamber via pipes. Two connecting pipes are fixedly connected to the input ends of the two dust pumps. The input ends of the four connecting pipes communicate with the interior of the annular tube. An exhaust port is located at the bottom of the dust collection chamber, and an air filter is fixedly connected to the inner wall of the exhaust port.

[0012] Equipped with an air filter, dust collection chamber, connecting pipe, annular pipe, suction port, dust pump, drive motor, and spiral blades, the dust collection chamber is designed to reduce internal pressure by expelling excess air through the exhaust port. The air filter retains dust within the chamber, preventing it from being released with the air and ensuring the device's effectiveness. The suction pump, connecting pipe, and annular pipe absorb dust, preventing workers from inhaling dust during drone recovery and thus improving safety. The dust collection chamber also allows workers to centrally process the dust.

[0013] A method for using a fully automatic topographic mapping device, comprising the following steps:

[0014] Step 1: When conducting topographic mapping, start the drive motor. The drive motor drives the spiral blades to rotate, which in turn causes the machine body to rise and the topographic mapping equipment to be drawn.

[0015] Step 2: During the surveying process, start the circulation pump. The circulation pump drives the coolant inside the cooling pipe to circulate, allowing the coolant to absorb the heat inside the heat-conducting fins and accelerate the release of heat from the coolant through the heat sink, thus preventing the control power supply from overheating. At the same time, the buffer spring rod can reduce the vibration received by the surveying base.

[0016] Step 3: Before landing, start the dust pump. The dust pump sucks in the air and draws the external dust into the annular pipe through the suction port. The dust is then transported to the dust collection chamber through the connecting pipe to reduce the dust generated during landing. Excess air is discharged through the air filter.

[0017] Step 4: During landing, the curved support legs and auxiliary support rods will simultaneously contact the ground and rotate. At this time, the connecting rod can drive the elastic element to move inside the movable opening. When all four curved support legs are in contact with the ground, the elastic element will engage with the protrusion, thereby fixing the curved support legs and allowing the aircraft to land smoothly on the uneven ground.

[0018] As can be seen from the above, the fully automatic topographic mapping equipment provided by the present invention has an automatic adjustment function. When in use, the device can automatically adjust the angle of a single arc-shaped support leg according to the unevenness of the ground, so that the UAV can maintain a horizontal state after landing and improve its stability.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The fully automatic topographic mapping equipment disclosed in this invention is mainly used in scenarios where drones are prone to tipping over and being damaged when landing on complex and uneven terrain.

[0029] Reference Figure 1-7A fully automatic topographic mapping device includes a body 1 and a mapping base 10. Four fixed legs 6 are fixedly connected to the outside of the mapping base 10, and one end of each fixed leg 6 is rotatably connected to an arc-shaped support leg 25. Mounting components 27 are fixedly connected to the outer walls of each of the four arc-shaped support legs 25, and auxiliary support rods 8 are rotatably connected to the inside of each of the four mounting components 27. The same torsion spring 28 is fixedly connected to the inner walls of both sides of each of the four mounting components 27, and the outer walls of the four torsion springs 28 respectively contact the outer walls of the four auxiliary support rods 8. Mounting holes 26 are opened on one side of the outer wall of each of the four fixed legs 6, and mounting rods 29 are rotatably connected to the inside of each of the four mounting holes 26. Connecting rods 30 are fixedly connected to both ends of each of the four mounting rods 29. Two connecting rods 30 on the same mounting rod 29 are fixedly connected to the same fixed rod 3 on opposite sides of their outer walls. 1. Each of the four arc-shaped support legs 25 has an opening 36 on one side of its outer wall. The four fixed rods 31 are located inside the four openings 36. Multiple protrusions 34 are fixedly connected at equal intervals on one side of the inner wall of each of the four openings 36. Elastic members 33 are fixedly connected to the outer walls of each of the four fixed rods 31. The outer walls of the four elastic members 33 are in contact with the outer walls of the four protrusions 34. Each of the four arc-shaped support legs 25 has a reset opening 35 on one side of its outer wall. The four reset openings 35 are connected to the four openings 36. Pressure rods 32 are fixedly connected to the outer walls of each of the four elastic members 33. The four pressure rods 32 are located inside the four reset openings 35. Support springs 24 are fixedly connected to the outer walls of each of the four fixed legs 6. One end of each support spring 24 is fixedly connected to the outer wall of each of the four arc-shaped support legs 25.

[0030] Specifically, during descent, one of the arc-shaped support legs 25 and the auxiliary support rod 8 will preferentially contact the higher ground. At this time, both the arc-shaped support leg 25 and the auxiliary support rod 8 will rotate, and they will rotate to the sides respectively. At the same time, the mounting rod 29 can drive the connecting rod 30 to rotate, and then the connecting rod 30 will drive the fixing rod 31 and the elastic element 33 to slide inside the movable opening 36. During the continued descent, all four arc-shaped support legs 25 and the auxiliary support rod 8 will gradually contact the ground. When all four arc-shaped support legs 25 and the four auxiliary support rods 8 are in contact with the ground, the device can fully support the body 1 and the surveying base 10 and lift them. At this time, the arc-shaped support leg 25 stops rotating, and the elastic element 33 engages with the protrusion, thereby fixing the four arc-shaped support legs 25 respectively, so that the body 1 lands smoothly.

[0031] In specific application scenarios, the four arc-shaped support legs 25 can automatically adjust the angle of each arc-shaped support leg 25 according to the unevenness of the ground during landing, so that the drone can maintain a horizontal state after landing, avoiding the drone from tipping over and being damaged, thus improving the effectiveness of the device. During landing, the torsion spring 28 and the auxiliary support rod 8 can increase the support effect on the drone, further improving the stability during landing. When the staff retrieves the device, the torsion spring 28 can drive the auxiliary support rod 8 to automatically reset, and pressing the pressure rod 32 can separate the elastic element 33 from the protrusion 34, and the support spring 24 can drive the arc-shaped support legs 25 to quickly reset. The operation is convenient and quick, and it is convenient for subsequent use.

[0032] In a preferred embodiment, four buffer sleeve rods 22 are fixedly connected to the bottom of the body 1. Buffer rods 23 are slidably connected inside each of the four buffer sleeve rods 22, and the bottom ends of the four buffer rods 23 are fixedly connected to the top of the surveying base 10. The top of the surveying base 10 is provided with the surveying equipment body 9. Four buffer spring rods 21 are fixedly connected to the bottom of the body 1. The four buffer spring rods 21 are respectively located inside the four buffer sleeve rods 22, and the bottom ends of the four buffer spring rods 21 are fixedly connected to the top of the four buffer rods 23.

[0033] Specifically, during the surveying process, the vibration generated by the rotation of the spiral blade 7 can be transmitted to the buffer rod 23 through the buffer sleeve 22. At this time, the buffer rod 23 will move up and down inside the buffer sleeve 22, thereby squeezing the buffer spring rod 21 and causing the buffer spring rod 21 to deform.

[0034] In specific application scenarios, since the buffer spring rod 21 has the function of buffering and absorbing energy, when the buffer rod 23 squeezes it, the buffer spring rod 21 can absorb the vibration of the buffer rod 23, thereby reducing the impact of the vibration generated by the rotation of the spiral blade 7 on the surveying base 10 and ensuring the accuracy of topographic mapping.

[0035] In a preferred embodiment, the outer walls of the four buffer sleeves 22 are fixedly connected to the same heat-conducting base plate 16. The top of the heat-conducting base plate 16 is fixedly connected to the bottom of the body 1, and multiple heat-conducting plates 20 are fixedly connected to the top of the heat-conducting base plate 16. One side of the outer wall of each of the multiple heat-conducting plates 20 is in contact with the outer wall of the control power supply 15. One side of the outer wall of each of the multiple heat-conducting plates 20 is provided with a through hole 19. The inner wall of the multiple through holes 19 on the same side is fixedly connected to the same cooling pipe 18, and the outer wall of each of the four cooling pipes 18 is provided with a circulation pump 17. The bottom of the body 1 and the top of the heat-conducting base plate are fixedly connected to multiple heat sinks 37, and one side of the outer wall of each of the multiple heat sinks 37 is provided with an opening. The outer walls of the four cooling pipes 18 are respectively fixedly connected to the inner walls of the multiple openings.

[0036] Specifically, during the surveying process, the control power supply 15 will generate heat. At this time, the heat-conducting base plate 16 and the heat-conducting plate 20 can absorb the heat of the control power supply 15. At the same time, the circulation pump 17 is started. The circulation pump 17 can drive the coolant inside the cooling pipe 18 to circulate, thereby absorbing the heat inside the heat-conducting plate 20, and cooling the coolant through the heat sink 37 during the circulation process.

[0037] In specific application scenarios, the heat-conducting base plate 16 and heat-conducting fins 20 absorb the temperature generated by the control power supply 15, thereby improving the heat dissipation effect of the control power supply 15. Furthermore, airflow can dissipate heat from the heat-conducting fins 20 and the heat-conducting base plate 16. Simultaneously, the multiple heat-conducting fins 20 increase the contact between the heat-conducting fins 20 and the air during measurement, further enhancing the heat dissipation effect of the device. The circulating pump 17 and cooling pipe 18 cool the heat-conducting fins 20, enabling them to quickly absorb the heat generated by the control power supply 15 and extending its service life. The heat sink 37 rapidly cools the coolant inside the cooling pipe 18. The cooling effect of the cooling pipe 18 on the heat-conducting fins 20 further enhances the heat absorption efficiency of the heat-conducting fins 20, increasing the practicality of the device.

[0038] In a preferred embodiment, the top of the body 1 has four mounting grooves, and each of the four mounting grooves is fixedly connected to a drive motor 11. The output shafts of the four drive motors 11 are all connected to spiral blades 7 via couplings. The top of the body 1 is also provided with a dust collection chamber 2. The outer walls of both sides of the surveying base 10 are fixedly connected to fasteners 12. The inner walls of the two fasteners 12 are fixedly connected to the same annular tube 5. The outer walls of the annular tube 5 are provided with multiple suction ports 14 at equal intervals. The outer walls of both sides of the dust collection chamber 2 are connected to dust pumps 4 via pipes. The input ends of the two dust pumps 4 are fixedly connected to two connecting pipes 13. The input ends of the four connecting pipes 13 are all connected to the interior of the annular tube 5. The bottom of the dust collection chamber 2 is provided with an exhaust port. The inner wall of the exhaust port is fixedly connected to an air filter 3.

[0039] Specifically, when conducting topographic mapping, the drive motor 11 is started, which drives the spiral blades 7 to rotate, causing the machine body 1 to lift the mapping equipment body 9. The mapping equipment body 9 then conducts topographic mapping. Before landing, the spiral blades 7 blow up the dust on the ground. At this time, the dust pump 4 is started. The dust pump 4 sucks the dust into the annular pipe 5 through the dust suction port 14, and then transports it to the connecting pipe 13. The dust enters the dust collection chamber 2 through the connecting pipe 13, and then the excess air is discharged through the exhaust port.

[0040] In specific application scenarios, the exhaust port can reduce the internal pressure of the dust collection chamber 2 by expelling excess air, and the air filter 3 can retain dust inside the dust collection chamber 2 to prevent dust from being discharged with the air and ensure the effectiveness of the device. The dust pump 4, connecting pipe 13 and annular pipe 5 can absorb the dust, preventing the staff from inhaling dust and causing discomfort when recovering the drone, thereby improving the safety of the device. At the same time, the dust collection chamber 2 allows the staff to centrally process the dust.

[0041] A method for using a fully automatic topographic mapping device, comprising the following steps:

[0042] Step 1: When conducting topographic mapping, start the drive motor 11. The drive motor 11 drives the spiral blades 7 to rotate, which causes the machine body 1 to lift the surveying equipment body 9, and then the topographic map is drawn through the surveying equipment body 9.

[0043] Step 2: During the surveying process, the control power supply 15 will generate heat. At this time, the heat-conducting base plate 16 and the heat-conducting plate 20 can absorb the heat of the control power supply 15. At the same time, the circulation pump 17 is started, which can drive the coolant inside the cooling pipe 18 to circulate, thereby absorbing the heat inside the heat-conducting plate 20. During the circulation process, the coolant is cooled by the heat sink 37 to prevent the control power supply 15 from overheating. Meanwhile, the vibration generated when the spiral blade 7 rotates can be transmitted to the buffer rod 23 through the buffer sleeve 22. At this time, the buffer rod 23 will move up and down inside the buffer sleeve 22, thereby squeezing the buffer spring rod 21, causing the buffer spring rod 21 to deform and reducing the vibration received by the surveying base 10.

[0044] Step 3: Before landing, the spiral blades 7 will blow up the dust on the ground. At this time, the dust pump 4 will be started. The dust pump 4 will suck the dust into the annular pipe 5 through the dust suction port 14 opened on the annular pipe 5, and then transport it to the connecting pipe 13, so that the dust enters the dust collection chamber 2 through the connecting pipe 13, and then the excess air is discharged through the exhaust port.

[0045] Step 4: During descent, one of the arc-shaped support legs 25 and the auxiliary support rod 8 will preferentially contact the higher ground. At this time, both the arc-shaped support leg 25 and the auxiliary support rod 8 will rotate, and they will rotate to both sides respectively. At the same time, the mounting rod 29 can drive the connecting rod 30 to rotate, which in turn drives the fixing rod 31 and the elastic element 33 to slide inside the movable opening 36. During the continued descent, all four arc-shaped support legs 25 and the auxiliary support rod 8 will gradually contact the ground. When all four arc-shaped support legs 25 and the four auxiliary support rods 8 are in contact with the ground, the device can fully support the body 1 and the surveying base 10 and lift them. At this time, the arc-shaped support leg 25 stops rotating, and the elastic element 33 engages with the protrusion, thereby fixing the four arc-shaped support legs 25 respectively, so that the body 1 lands smoothly.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

A method of using a fully automatic topographic mapping device, comprising using a fully automatic topographic mapping device as described in claim 6, characterized in that, Includes the following steps: Step 1: When conducting topographic mapping, start the drive motor (11), drive the spiral blades (7) to rotate through the drive motor (11), so that the machine body (1) drives the surveying equipment body (9) to rise, and then conduct topographic mapping through the surveying equipment body (9); Step 2: During the surveying process, start the circulation pump (17). The circulation pump (17) drives the coolant inside the cooling pipe (18) to circulate, so that the coolant absorbs the heat inside the heat-conducting plate (20) and accelerates the release of heat inside the coolant through the heat sink (37), thus preventing the control power supply (15) from overheating. At the same time, the buffer spring rod (21) can reduce the vibration received by the surveying base. Step 3: Before landing, start the dust pump (4). The dust pump (4) sucks in the air and then sucks the external dust into the annular pipe (5) through the dust inlet (14). Then, it is transported to the dust collection bin (2) through the connecting pipe (13) to reduce the dust generated during landing and exhaust the excess air through the air filter (3). Step 4: During landing, the arc-shaped support leg (25) and the auxiliary support rod (8) will simultaneously come into contact with the ground and rotate. At this time, the connecting rod (30) can drive the elastic element (33) to move inside the movable opening (36). When all four arc-shaped support legs (25) are in contact with the ground, the elastic element (33) will engage with the protrusion (34) to fix the arc-shaped support leg (25) so that the body (1) can land smoothly on the uneven ground.
