[0002] With the development of society, many fields such as railways, electricity, bridges, ships and offshore wind power are beginning to face the problem of structural corrosion. Structural corrosion will affect the service life and safety of the structure. Therefore, it is necessary to evaluate the corrosion of the structure to ensure the safety of the structure. In the fields of railways, electricity, bridges, ships and offshore wind power, there are many high-altitude structures, and the corrosion problem of high-altitude structures has always been checked manually in the past.

[0003] With the development of drones, thickness gauges are mounted on drones to measure the corrosion thickness of high-altitude structures, becoming one of the main methods for measuring the corrosion degree of high-altitude structures. However, when the thickness gauge is mounted on a drone, it loses the advantage of convenient application on the ground side, resulting in the thickness gauge removed from the drone being unable to measure the corrosion degree of ground structures. Therefore, how to make the thickness gauge both able to be carried on drones for inspections and to be easily converted into a ground corrosion degree measurement device after being removed from the drone has become an urgent problem to be solved. Summary of the invention

[0036] 1 and 2 , an air-to-ground dual-purpose thickness measurement conversion device 10 provided in one embodiment of the present application includes a converter 1 and a pan / tilt platform 2, wherein:

[0037] The converter 1 includes a control box 12, a control assembly (not shown), a telescopic leg 17 and a conversion shaft 11. The control assembly is arranged in the control box 12. One end of the telescopic leg 17 is rotatably connected to the control box 12. The other end of the telescopic leg 17 is provided with a universal wheel 18. The telescopic leg 17 can be extended and retracted along the length direction of the telescopic leg 17, and the telescopic leg 17 can be folded on the bottom surface of the control box 12 by rotating relative to the control box 12. The conversion shaft 11 is arranged in the control box 12, and the conversion shaft 11 is used to be detachably connected to the drone 100. The gimbal 2 is connected to the control box 12; the gimbal 2 is used to be detachably connected to the thickness measuring device 30, and the control assembly is used to communicate and connect with the drone 100, the thickness measuring device 30 and the console 40.

[0038] As shown in FIG. 1 and FIG. 2 , in the above-mentioned air-ground dual-purpose thickness measurement conversion device 10, the control box 12 is connected to the telescopic legs 17, and the pan-tilt 2 is arranged on the control box 12, so that the control box 12 can be reliably supported on the ground through the telescopic legs 17, and the thickness measuring device 30 can be reliably fixed to the control box 12 through the pan-tilt 2. Since when the thickness measuring device 30 is fixed to the pan-tilt 2, the control component can simultaneously communicate with the console 40 and the thickness measuring device 30, so when the thickness measuring device 30 is installed in the air-ground dual-purpose thickness measurement conversion device 10, the control component can control the thickness measuring device 30 to perform the thickness measurement operation under the control of the console 40, so that the thickness measuring device 30 can measure the corrosion degree of the structure on the ground side, and then the thickness measuring device 30 can also feed back the acquired thickness data to the console 40 through the control component, so that the user can easily obtain the measurement result at the console 40 to complete the measurement of the ground structure. Since the conversion shaft 11 provided on the control box 12 can be detachably connected to the drone 100, and the control component can be communicatively connected to the drone 100 and the thickness measuring device 30 at the same time, the thickness measuring device 30 can be conveniently disassembled and assembled with the drone 100 through the air-to-ground dual-purpose thickness measurement conversion device 10, so that the thickness measuring device 30 can be carried on the drone 100 for high-altitude inspection, and during the high-altitude inspection, the thickness measuring device 30 can communicate with the drone 100 through the control component, so that the drone 100 can adjust its flight state in time according to the data transmitted by the thickness measuring device 30, so as to complete the corrosion degree measurement of the high-altitude structure, and ensure the reliability of the measurement results of the thickness measuring device 30 at high altitude. In addition, since the length of the telescopic legs 17 can be adjusted and the telescopic legs 17 are provided with universal wheels 18, when the thickness measuring device 30 is installed on the air-ground dual-purpose thickness measuring conversion device 10 and used to measure the corrosion thickness of the ground structure, the air-ground dual-purpose thickness measuring conversion device 10 can conveniently adjust the height and position of the thickness measuring device 30 through the telescopic legs 17 and the universal wheels 18, so that the thickness measuring device 30 can quickly align with the measured position to accurately measure. When the thickness measuring device 30 is carried on the drone 100, since the telescopic legs 17 can be folded at the bottom of the control box 12, the telescopic legs 17 will not cause interference during the flight, ensuring the stability during the high-altitude inspection process. Therefore, through the air-ground dual-purpose thickness measuring conversion device 10, the thickness measuring device 30 can be carried on the drone 100 to measure the corrosion degree of the high-altitude structure, and can be quickly and simply converted into a ground-based mobile thickness gauge after being removed from the drone 100, retaining the advantage of the convenient application of the thickness measuring device 30 on the ground. Therefore, the air-ground dual-use thickness measurement conversion device 10 solves the problem that the thickness measuring device 30 can be used both in the air and on the ground, greatly improves the utilization efficiency of the thickness measuring device 30, saves labor costs, and realizes all-round and fast detection of the thickness measuring device 30.

[0039] Optionally, when the thickness measuring device 30 is installed on the pan / tilt platform 2, the thickness measuring device 30 is connected to the converter 1 via a cable. The converter 1 is connected to the console 40 by wireless communication, such as WiFi connection, Bluetooth connection, etc.

[0040] Specifically, the console 40 is a control center for remotely controlling the thickness measuring device 30 and the drone 100. The console 40 can control the execution of the thickness measuring device 30 through the control component of the converter 1, such as starting and stopping the measurement; the thickness measuring device 30 can feed back the detected data and its operating status to the console 40 through the control component, so that the user can easily obtain the thickness of the rust layer at the measurement position at the console 40. The console 40 can also be connected to the drone 100 by wireless communication, so that the console 40 can control the flight altitude, flight attitude, etc. of the drone 100 during the flight, so that the thickness measuring device 30 carried on the drone 100 can accurately measure the corrosion degree of the high-altitude structure.

[0041] Optionally, the thickness measuring device 30 can be a non-contact thickness measuring device 30, so that the thickness measuring device 30 can rely on optical or acoustic wave technology, such as laser or ultrasonic wave, to measure the distance of the surface of the object, thereby determining the thickness of the object. Schematically, when the thickness measuring device 30 has a probe 32, when the thickness measuring device 30 measures the degree of corrosion, the probe 32 is opposite to the easily corroded part of the structure to be measured, so that the laser emitted by the probe 32 can be reflected on the surface of the structure to be measured and received by the probe 32, so that the thickness measuring device 30 can determine the thickness of the rust layer of the structure to be measured according to the time it receives the reflected laser and the principle of photothermal method. Among them, since there is no contact between the thickness measuring device 30 and the structure to be measured during the measurement process, the thickness measuring device 30 can realize non-destructive detection of the thickness of the rust layer to obtain thickness data that is closer to the actual situation. In addition, the influence of strong electromagnetic fields on the measurement results can be avoided.

[0042] In one embodiment, as shown in FIG. 1 and FIG. 2 , the conversion shaft 11 is movably connected to the control box 12, and the conversion shaft 11 has a connection state protruding from the control box 12, and a storage state retracted in the control box 12. In the connection state, the conversion shaft 11 can be detachably connected to the drone 100. In this way, the air-to-ground dual-purpose thickness measurement conversion device 10 can choose whether to retract the conversion shaft 11 according to whether the drone 100 is connected. Specifically, when the thickness measuring device 30 needs to perform high-altitude inspection, the conversion shaft 11 protrudes from the control box 12 to ensure that the thickness measuring device 30 can be conveniently connected to the drone 100 through the conversion shaft 11. When the thickness measuring device 30 measures the corrosion thickness of the ground structure, the conversion shaft 11 is stored in the control box 12 to avoid the conversion shaft 11 from colliding with other equipment during movement, thereby ensuring the safety of the overall equipment during the measurement process.

[0043] Schematically, as shown in FIG1 , when the conversion shaft 11 protrudes from the control box 12, the portion of the conversion shaft 11 protruding from the control box 12 and the telescopic legs 17 are respectively located on opposite sides of the control box 12, so that the arrangement of the telescopic legs 17 does not interfere with the connection between the conversion shaft 11 and the drone 100. In addition, when the conversion shaft 11 is retracted in the control box 12, the upper surface of the control box 12 can be used to place items, such as a computer, a notebook, etc.

[0044] Optionally, in one embodiment, the converter 1 further includes a lifting member, which is disposed in the control box 12 and connected to the control assembly, and the lifting member is drivingly connected to the conversion shaft 11, and the conversion shaft 11 can switch between a connected state and a stored state under the drive of the lifting member. In this way, the lifting and lowering of the conversion shaft 11 can be conveniently controlled by the lifting member. Schematically, the lifting member can be a telescopic motor. In another embodiment, the converter 1 may include an elastic member and a positioning member, and the elastic member is disposed in the control box 12 and connected to the conversion shaft 11, and the elastic member is used to switch the conversion shaft 11 from a stored state to a connected state. The positioning member is used to fix the conversion shaft 11 in a stored state or a connected state.

[0045] In one embodiment, as shown in FIG. 1 , the telescopic leg 17 includes a first set of rods 171 and a second set of rods 172. One end of the first set of rods 171 is rotatably connected to the control box 12, and the other end is slidably mounted on one end of the second set of rods 172. The end of the second set of rods 172 that is away from the first set of rods 171 is connected to the universal wheel 18. The telescopic leg 17 also includes a fixing member, which is used to fix the relative position of the first set of rods 171 and the second set of rods 172. In this way, when the measuring device measures the corrosion thickness of the structure at the ground end, the length of the telescopic leg 17 can be adjusted by sliding the second set of rods 172 relative to the first set of rods 171, and then the telescopic leg 17 can be fixed to the corresponding length by the fixing member, so as to achieve the height adjustment of the control box 12 and the thickness measuring device 30, so that the thickness measuring device 30 can be easily aligned with the measured position to ensure the reliability of the measurement result.

[0046] Optionally, the first rod 171 can be slidably sleeved on the outer periphery of the second rod 172. Alternatively, the second rod 172 can be slidably sleeved on the outer periphery of the second rod 172.

[0047] Schematically, in one embodiment, the first rod 171 is slidably mounted on the outer periphery of the second rod 172, the second rod 172 is provided with a positioning groove, the fixing member includes a positioning column and a spring, the spring is installed in the positioning groove, one end of the positioning column extends into the positioning groove and is connected to the spring, and the other end protrudes from the second rod 172, the first rod 171 is formed with a plurality of fixing grooves arranged along the length direction of the telescopic leg 17, and the portion of the positioning column protruding from the second rod 172 can be matched with the fixing groove to relatively fix the first rod 171 and the second rod 172. In this way, the telescopic leg 17 can be extended and retracted by matching the positioning column with different fixing grooves. In another embodiment, the first rod 171 is slidably mounted on the outer periphery of the second rod 172, the first rod 171 is formed with a plurality of thread grooves arranged along the length direction of the telescopic leg 17, the fixing member is a screw, the screw is threadedly matched with the thread groove, and the screw can relatively fix the first rod 171 and the second rod 172 by abutting against the second rod 172.

[0048] In another embodiment, as shown in FIG. 1 , the telescopic leg 17 includes a first set of rods 171 and a second set of rods 172. One end of the first set of rods 171 is rotatably connected to the control box 12, and the other end is slidably mounted on one end of the second set of rods 172. The end of the second set of rods 172 that is away from the first set of rods 171 is connected to the universal wheel 18. The telescopic leg 17 also includes a telescopic member provided on the first set of rods 171. The telescopic member is drivingly connected to the second set of rods 172. The second set of rods 172 can slide relative to the first set of rods 171 under the action of the telescopic member. In this way, when the thickness measuring device 30 measures the corrosion thickness of the structure at the ground end, the telescopic member can adjust the length of the telescopic leg 17 by driving the second set of rods 172 to slide relative to the first set of rods 171, so as to achieve height adjustment of the control box 12 and the thickness measuring device 30, so that the thickness measuring device 30 can be easily aligned with the measured position to ensure the reliability of the measurement result.

In this way, the multiple telescopic legs 17 can jointly support the control box 12 to ensure the stability of the air-to-ground dual-purpose thickness measurement conversion device 10. In addition, the multiple telescopic legs 17 are arranged on the periphery of the pan-tilt 2, so that the multiple telescopic legs 17 can also protect the thickness measuring device 30 arranged on the pan-tilt 2 to prevent the thickness measuring device 30 from being hit by external structures.

[0051] In one embodiment, as shown in FIG. 1 and FIG. 2, the pan-tilt platform 2 includes an adjustment component 21, a fixing plate 22, and a driving component. The adjustment component 21 is connected to the control box 12 and the fixing plate 22. The fixing plate 22 is used to be detachably connected to the thickness measuring device 30. The driving component is drivingly connected to the adjustment component 21. The driving component is electrically connected to the control component. The adjustment component 21 can adjust the position and pitch angle of the thickness measuring device 30 under the drive of the driving component. In this way, when the thickness measuring device 30 is arranged on the pan-tilt platform 2, the driving component can drive the adjustment component 21 to move under the control of the control component, so that the thickness measuring device 30 can move relative to the control box 12 under the drive of the fixing plate 22, so that the thickness measuring device 30 can better align with the measured part of the structure to be measured, so as to more accurately measure the corrosion thickness of the structure to be measured.

[0052] Optionally, the fixing plate 22 and the thickness measuring device 30 are fixed by screws.

[0053] Further, in combination with FIG. 1 and FIG. 2, the adjustment assembly 21 includes a connecting rod 211, a first rotating shaft 212, a second rotating shaft 213 and a third rotating shaft 214, one end of the connecting rod 211 is connected to the control box 12, and the other end is rotatably connected to the first rotating shaft 212, the connecting rod 211 and the first rotating shaft 212 are arranged at an angle, the second rotating shaft 213 is arranged on the side of the first rotating shaft 122 away from the connecting rod 211, and one end of the second rotating shaft 213 is rotatably connected to the first rotating shaft 212, and the other end is rotatably connected to the third rotating shaft 214. Rotationally connected, the second rotating shaft 213 is set at an angle with the first rotating shaft 212 and the third rotating shaft 214, the third rotating shaft 214 is connected to the fixed plate 22, the first rotating shaft 212, the second rotating shaft 213 and the third rotating shaft 214 are all connected to the driving assembly, the first rotating shaft 212 can drive the thickness measuring device 30 to rotate around the connecting rod 211 under the drive of the driving assembly, and the second rotating shaft 213 can drive the thickness measuring device 30 to rotate around the axis of the second rotating shaft 213 under the drive of the driving assembly. The third rotating shaft 214 can drive the thickness measuring device 30 to rotate around the axis of the third rotating shaft 214 under the action of the driving assembly. In this way, when the thickness measuring device 30 is set on the gimbal 2, the gimbal 2 can not only ensure the stability of the thickness measuring device 30 when the drone 100 shakes or the bottom surface moves. It can also effectively drive the thickness measuring device 30 to realize multi-angle rotation to adjust its position and pitch angle, so that the thickness measuring device 30 can better align with the measured part of the structure to be measured, so as to ensure that the thickness measuring device 30 can more accurately measure the corrosion thickness of the structure to be measured. Specifically, since the first rotating shaft 212 can rotate around the connecting rod 211 under the action of the driving component, the second rotating shaft 213 can act around its axial direction under the action of the driving component, and the first rotating shaft 212 and the second rotating shaft 213 are arranged at an angle, when the driving component drives the first rotating shaft 212 and the second rotating shaft 213 to rotate, the fixing plate 22 can drive the thickness measuring device 30 to move flexibly at the same horizontal height under the joint action of the first rotating shaft 212 and the second rotating shaft 213, so as to conveniently adjust the position of the thickness measuring device 30 at the same horizontal height, so that the thickness measuring device 30 can better align with the measured position of the structure to be measured. When the third rotating shaft 214 rotates around its axis under the action of the driving assembly, the fixed plate 22 can drive the thickness measuring device 30 to rotate around the horizontal plane where the axis of the third rotating shaft 214 is located. Therefore, the third rotating shaft 214 can adjust the pitch angle of the thickness measuring device 30 under the drive of the driving assembly, which enables the pan-tilt head 2 to further flexibly adjust the posture of the thickness measuring device 30 to ensure the flexibility and reliability of the thickness measuring device 30 during the measurement process.

[0060] Optionally, as shown in FIG1 , the converter 1 further includes a power module 16, which is disposed in the control box 12 and is used to provide power to the control component and the thickness measuring device 30. In this way, the air-to-ground dual-purpose thickness measuring conversion device 10 and the thickness measuring device 30 can easily obtain the required energy to work without being connected to the power grid. At the same time, this also ensures that the air-to-ground dual-purpose thickness measuring conversion device 10 and the thickness measuring device 30 can be carried on the drone 100 for high-altitude inspection.

[0062] In the above-mentioned thickness measuring device 200, since the thickness measuring device 30 can be reliably installed on the air-to-ground dual-purpose thickness measurement conversion device 10 through the pan-tilt head 2, and the control component can communicate and connect the probe 32 of the thickness measuring device 30 and the console 40, when the thickness measuring device 30 is installed on the air-to-ground dual-purpose thickness measurement conversion device 10, the thickness measuring device 200 can measure the corrosion degree of the structure on the ground side, and the user can easily obtain the measurement results through the console 40, thereby completing the measurement of the ground structure.
