Description

Technical Field

[0001] The present invention belongs to the technical field of X-ray inspection devices, and in particular relates to an X-ray inspection device for overhead power transmission lines based on an unmanned aerial vehicle platform. Background Art

[0002] X-ray inspection of overhead transmission lines is a method of non-destructive testing of key components such as tension clamps of overhead transmission lines using X-ray technology. During the operation of overhead transmission lines, the connection quality of tension clamps and other crimping hardware is crucial. These hardware not only have to bear the conductive function of the wires, but also the full tension of the wires. Therefore, testing their crimping quality is a key link to ensure reliable operation of the lines and safe power supply. Through X-ray inspection, it can be clearly found whether there are defects in the crimping quality and content of the tension clamps, such as undervoltage, leakage, empty pressure, and crimping misalignment. These defects are difficult to detect under visual inspection, but once they exist, they will leave major safety hazards such as abnormal heating and disconnection of the wires during operation. Therefore, X-ray inspection technology is of great significance for preventing potential safety accidents;

[0003] However, because overhead transmission lines are set at high altitudes, the traditional inspection method is to carry X-ray inspection devices on the back of workers, which not only increases the weight of tools carried by workers when working at heights, but also increases the danger of workers working at heights. In addition, when workers hold X-ray inspection devices for inspection, the inspection is difficult because they are at high altitudes, which can lead to incomplete inspection positions and missed inspections.

[0036] Embodiment 1

[0037] Furthermore:

[0038] As Figures 1 to 11 shown;

[0039] Combining the above content:

[0040] In order to implement the X-ray inspection device for overhead transmission lines based on the drone platform when using the drone X-ray inspection device, it includes the drone platform main body 1, and also includes a lifting component 2 arranged on the bottom surface of the drone platform main body 1. The lifting component 2 includes a rubber plate 23. One end of the rubber plate 23 away from the drone platform main body 1 is provided with a mounting component 3. The mounting component 3 includes a plug board 32. A rotating component 4 is arranged inside the plug board 32. The rotating component 4 includes a fixed seat 42. The surface of the fixed seat 42 is mounted with the X-ray inspection device main body 5.

[0041] The lifting component 2 includes a mounting shell 21. The mounting shell 21 is mounted on the bottom surface of the drone platform main body 1 through a mounting seat A. Inside the mounting shell 21 is provided with a rubber plate 23. A positioning rod is arranged inside the mounting shell 21. One end of the rubber plate 23 is fixedly connected to the positioning rod and wound around its surface. A motor A 22 is mounted on the surface of the mounting shell 21 through a mounting seat B. The output shaft of the motor A 22 penetrates inside the mounting shell 21 and is fixedly connected to the positioning rod.

[0042] In this implementation scheme: when in use, first connect the X-ray inspection device main body 5 to an external power supply and then start it, then connect the drone platform main body 1 to the power supply, and then control the external handle to make the drone platform main body 1 fly to an appropriate position. The images captured by the X-ray inspection device main body 5 can be observed through the external screen. When the drone platform main body 1 moves along the line direction, due to gravity, the line will have a certain arc change. The motor A 22 can be connected to an external power supply and then started. The output shaft of the motor A 22 drives the positioning rod to rotate. When the positioning rod rotates, the rubber plate 23 will extend towards the outside of the mounting shell 21, and the X-ray inspection device main body 5 will also move due to the extension of the rubber plate 23, facilitating the lens of the X-ray inspection device main body 5 to always face the line.

[0043] Even further:

[0044] In an alternative embodiment, a number of limiting grooves A24 are provided inside the rubber plate 23. A support plate 25 is provided inside each limiting groove A24. A positioning hole 28 is provided inside each support plate 25. A positioning shaft 26 is provided inside each positioning hole 28. The positioning shaft 26 is fixedly connected to the rubber plate 23. A torsion spring 27 is wound around the surface of the positioning shaft 26. Two ends of the torsion spring 27 are respectively fixedly connected to the positioning shaft 26 and the support plate 25. Two rubber seats 210 are fixedly connected to the surface of each support plate 25. Slots 29 are provided at the positions of the rubber plate 23 corresponding to the two rubber seats 210. The rubber seats 210 are slidably connected to the rubber plate 23 through the slots 29. The two rubber seats 210 are located on opposite sides of the support plate 25, and the two rubber seats 210 are not coaxial.

[0045] In this embodiment: When the rubber plate 23 extends outward from the mounting shell 21, the support plate 25 rotates about the positioning shaft 26 due to the elastic potential energy of the torsion spring 27. When the support plate 25 rotates, the rubber seat 210 slides out of the slot 29. Until a number of support plates 25 rotate to an appropriate angle, a number of support plates 25 are on the same axis. A cross shape is formed by the support plate 25 and the rubber plate 23. The rubber seat 210 abuts against another support plate 25, preventing the wind from blowing the X-ray inspection device main body 5 off the track due to weather conditions during the inspection of the X-ray inspection device main body 5, resulting in the X-ray inspection device main body 5 being unable to inspect the line, thereby reducing the work efficiency.

[0046] Furthermore:

[0047] In an alternative embodiment, a fixing block A211 is fixedly connected to the side of the mounting shell 21 away from the UAV platform main body 1. A chute 212 is provided inside the fixing block A211. The rubber plate 23 is slidably connected to the fixing block A211 through the chute 212. A spiral groove 213 is provided inside the fixing block A211. The support plate 25 is slidably connected to the fixing block A211 through the spiral groove 213. The opening direction of the end of the spiral groove 213 away from the mounting shell 21 is perpendicular to the chute 212, and the opening direction of the end of the spiral groove 213 close to the mounting shell 21 coincides with the chute 212.

[0048] In this embodiment: When the positioning rod winds up the rubber plate 23, the rubber plate 23 slides inside the chute 212. The support plate 25 is inserted into the spiral groove 213. The support plate 25 is limited due to the shape characteristics of the spiral groove 213. The support plate 25 rotates on the surface of the positioning shaft 26 until the support plate 25 is parallel to the rubber plate 23. The rubber plate 23 can then enter the inside of the mounting shell 21, achieving the storage of the rubber plate 23.

[0049] Furthermore:

[0050] In an alternative embodiment, a fixing shell 31 is fixedly connected to one end of the rubber plate 23 away from the mounting shell 21. An insertion plate 32 is arranged inside the fixing shell 31, and the insertion plate 32 is slidably connected to the fixing shell 31. An extrusion plate 33 is arranged inside the fixing shell 31. Two limiting plates A35 are symmetrically and fixedly connected to both ends of the extrusion plate 33. Fixing grooves 34 are symmetrically formed inside the fixing shell 31. The limiting plates A35 are arranged inside the fixing grooves 34, and the limiting plates A35 are slidably connected to the fixing shell 31 through the fixing grooves 34. Two positioning grooves 38 are symmetrically formed inside the fixing shell 31. The positioning grooves 38 communicate with the fixing grooves 34. A positioning cylinder 37 is arranged inside the positioning grooves 38. The positioning cylinder 37 is slidably connected to the fixing shell 31 through the positioning grooves 38. Two limiting plates B36 are symmetrically and fixedly connected to the surface of the positioning cylinder 37. The limiting plates B36 are in contact and fit with the limiting plates A35. One end of the positioning cylinder 37 is fixedly connected to a spring 311. The end of the spring 311 away from the positioning cylinder 37 is fixedly connected to a positioning block 310. Two jacks 39 are symmetrically formed on the surface of the insertion plate 32. The positioning block 310 is inserted into the jacks 39.

[0051] In this embodiment: When it is necessary to install the X-ray inspection device main body 5, the insertion plate 32 is inserted into the fixing shell 31. The extrusion plate 33 will be limited by the insertion plate 32 and drive the limiting plate A35 to slide inside the fixing groove 34. When the limiting plate A35 moves, it will limit the limiting plate B36, so that the positioning cylinder 37 moves inside the positioning groove 38 in the direction of the insertion plate 32 until the positioning block 310 is inserted into the jacks 39, realizing the limitation of the insertion plate 32 and thus realizing the installation of the X-ray inspection device main body 5.

[0052] Furthermore:

[0053] In an alternative embodiment, a pull rod 312 is arranged inside the positioning cylinder 37. One end of the pull rod 312 is fixedly connected to the positioning block 310. The end of the pull rod 312 away from the positioning block 310 penetrates through the fixing shell 31 and is fixedly connected to a limiting shaft 313. Two fixing blocks B316 are symmetrically and fixedly connected to the surface of the fixing shell 31. A handle 315 is rotatably connected to the surface of the fixing block B316. A limiting groove B314 is formed on the surface of the handle 315. The limiting shaft 313 is inserted into the limiting groove B314 and is slidably connected to the handle 315 through the limiting groove B314. An anti-slip sleeve 320 is fixedly connected to the end of the handle 315 away from the limiting groove B314. A sliding hole 317 is formed inside the fixing block B316. A sliding rod 318 is arranged inside the sliding hole 317. The sliding rod 318 is slidably connected to the fixing block B316 through the sliding hole 317. One end of the sliding rod 318 penetrates through the handle 315 and is slidably connected to it. One end of the sliding rod 318 is fixedly connected to a limiting rod 319. The limiting rod 319 is rotatably connected to the handle 315.

[0054] In this embodiment: When it is necessary to disassemble the X-ray inspection device main body 5, first press the limit rod 319, so that the sliding rod 318 slides into the inside of the sliding hole 317 from the inside of the handle 315 until the limit rod 319 enters the inside of the handle 315. Then, hold the anti-slip sleeve 320 and apply force to the handle 315. The handle 315 will rotate on the surface of the fixed block B316. The handle 315 will apply force to the limit shaft 313 due to the limit groove B314, so that the pull rod 312 slides inside the positioning cylinder 37, thereby pulling the positioning block 310, and making the positioning block 310 slide out from the inside of the jack 39, thus releasing the limit on the insertion plate 32, and realizing the removal of the X-ray inspection device main body 5. When the insertion plate 32 slides out from the inside of the fixed shell 31, the pressing plate 33 will drive the limit plate A35 to move inside the fixed groove 34. The positioning cylinder 37 will slide inside the positioning groove 38 due to the elastic potential energy of the spring 311. Then, release the force applied to the handle 315, and the positioning block 310 will return to its original position. Apply force to the limit rod 319 again, and slide the sliding rod 318 out from the inside of the sliding hole 317 until it is inserted into the inside of the handle 315, thus realizing the limit on the handle 315.

[0055] Furthermore:

[0056] In an alternative embodiment, fixing seats 42 are symmetrically and fixedly connected to the surface of the X-ray inspection device main body 5. One end of the insertion plate 32 away from the fixed shell 31 is located between the two fixing seats 42. A linkage rod 43 is fixedly connected to the inside of the insertion plate 32. Both ends of the linkage rod 43 are inserted into the inside of the two fixing seats 42 and are rotatably connected thereto. A motor B41 is mounted on the surface of the fixing seat 42 through a mounting seat C. The output shaft of the motor B41 is fixedly connected to the linkage rod 43.

[0057] In this embodiment: When the X-ray inspection device main body 5 needs to rotate an angle for line inspection, connect the motor B41 to an external power supply. The output shaft of the motor B41 will drive the insertion plate 32 to rotate through the linkage rod 43, thereby driving the X-ray inspection device main body 5 to rotate an angle.

[0058] Working principle:

[0059] In use, first connect the main body 5 of the X-ray inspection device to an external power supply and then start it. Next, connect the main body 1 of the drone platform to the power supply. Then, operate the external handle to fly the main body 1 of the drone platform to an appropriate position. You can observe the images captured by the main body 5 of the X-ray inspection device through the external screen. When the main body 1 of the drone platform moves along the line direction, due to gravity, the line will have a certain arc change. You can connect the motor A22 to an external power supply and then start it. The output shaft of the motor A22 drives the positioning rod to rotate. When the positioning rod rotates, it will cause the rubber plate 23 to extend outward from the installation shell 21. The main body 5 of the X-ray inspection device will also move due to the extension of the rubber plate 23, facilitating the lens of the main body 5 of the X-ray inspection device to always face the line. When the rubber plate 23 extends outward from the installation shell 21, the support plate 25 will rotate around the positioning shaft 26 due to the elastic potential energy of the torsion spring 27. When the support plate 25 rotates, the rubber seat 210 will slide out of the internal of the card slot 29. Until several support plates 25 rotate to an appropriate angle, several support plates 25 are on the same axis. The support plate 25 and the rubber plate 23 form a cross shape, and the rubber seat 210 will fit with another support plate 25, preventing the main body 5 of the X-ray inspection device from being blown off the track by the wind due to weather during inspection, resulting in the main body 5 of the X-ray inspection device being unable to inspect the line, thereby reducing work efficiency.

[0060] When the positioning rod winds up the rubber plate 23, the rubber plate 23 will slide inside the chute 212, and the support plate 25 will be inserted into the internal of the spiral groove 213. The support plate 25 will be limited due to the characteristics of the shape of the spiral groove 213. The support plate 25 will rotate on the surface of the positioning shaft 26 until the support plate 25 is parallel to the rubber plate 23, and the rubber plate 23 can enter the internal of the installation shell 21, realizing the storage of the rubber plate 23.

[0061] When it is necessary to install the main body 5 of the X-ray inspection device, insert the insertion plate 32 into the internal of the fixed shell 31. The extrusion plate 33 will be limited by the insertion plate 32 and drive the limit plate A35 to slide inside the fixed groove 34. When the limit plate A35 moves, it will limit the limit plate B36, causing the positioning cylinder 37 to move inside the positioning groove 38 in the direction of the insertion plate 32 until the positioning block 310 is inserted into the internal of the jack 39, realizing the limitation of the insertion plate 32, and thus realizing the installation of the main body 5 of the X-ray inspection device.

[0062] When it is necessary to disassemble the X-ray inspection device main body 5, first press the limit rod 319 to make the sliding rod 318 slide into the inside of the sliding hole 317 from the inside of the handle 315 until the limit rod 319 enters the inside of the handle 315. Then, hold the anti-slip sleeve 320 and apply force to the handle 315. The handle 315 will rotate on the surface of the fixed block B316. The handle 315 will apply force to the limit shaft 313 due to the limit groove B314, causing the pull rod 312 to slide inside the positioning cylinder 37, thereby pulling the positioning block 310 and making the positioning block 310 slide out of the inside of the jack 39, releasing the limit on the insertion plate 32 and realizing the removal of the X-ray inspection device main body 5;

[0063] When the insertion plate 32 slides out of the inside of the fixed housing 31, the pressing plate 33 will drive the limit plate A35 to move inside the fixed groove 34. The positioning cylinder 37 will slide inside the positioning groove 38 due to the elastic potential energy of the spring 311. Then, release the force applied to the handle 315, and the positioning block 310 will return to its original position. Apply force to the limit rod 319 again to slide the sliding rod 318 out of the inside of the sliding hole 317 until it is inserted into the inside of the handle 315, thus realizing the limitation of the handle 315.
