Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1-4 As shown, a UAV-mounted X-ray inspection device for single and double split conductors includes a support plate 1, with an adjustable hoisting assembly 2 mounted on its outer surface. A detector is mounted on the bottom surface of the support plate 1, and the support plate 1 is connected to a connecting frame 3 and a U-shaped mounting frame 4 below it. An emission shielding chamber 5, made of aluminum alloy, is located inside the U-shaped mounting frame 4. The emission shielding chamber 5 is connected to the inner wall of the U-shaped mounting frame 4 via two mounting assemblies 6. An operating door 7 is located on the front of the emission shielding chamber 5. An X-ray machine is installed inside the emission shielding chamber. An X-ray emission outlet 8 is opened on the end face of the emission shielding chamber 5, and a set of heat dissipation holes 9 are opened on both the left and right sides of the emission shielding chamber 5.

[0028] The distance between the detector and the X-ray machine is 1.8m to 2.0m. Both the connecting frame 3 and the U-shaped mounting frame 4 are made of electrically insulating material with an electrical insulation performance greater than 220KV.

[0029] The adjustable hoisting assembly 2 includes two slide rails 201, which are arranged parallel to each other and connected on the upper surface of the support plate 1. Each slide rail 201 has a groove with an inverted T-shaped cross section. A T-shaped slider 203 is slidably connected in the groove. A connecting plate 204 is provided between the two T-shaped sliders 203, and a drone connector 260 is installed on the upper surface of the connecting plate 204. The drone connector 260 is a lifting ring.

[0030] The vertical part of the T-shaped slider 203 is provided with a vertical threaded hole, the horizontal part of the T-shaped slider 203 is provided with a through hole, and the threaded hole is communicated to the through hole, two jacks are arranged in the through hole, the opposite ends of the two jacks are hemispherical structures, and an adjusting bolt is arranged in the threaded hole of the T-shaped slider 203, and the end of the adjusting bolt is a conical structure.

[0031] The specific structure of the jack has two forms:

[0032] First, the end face of the opposite end of the two jacks is a plane, and the plane is provided with a pattern for increasing friction, and the inner wall of the sliding groove of the sliding rail 201 is provided with a pattern.

[0033] Second, the horizontal through hole of the slider 203 is provided with a neck at both ends, the opposite end of the two jacks is a hemispherical structure, the diameters of the two ends of the horizontal through hole are smaller than the diameter of the jack, and the surface of the hemispherical structure of the opposite end of the jack is provided with a pattern, and the inner wall of the sliding groove of the sliding rail 201 is provided with a pattern.

[0034] The connecting plate 204 can adjust the position of the end face on the bearing plate 1 through the sliding of the slider 203, so that it is located at the center or deviated position, the connecting plate 204 is provided with a lifting ring for connecting the unmanned aerial vehicle, and different positions of the connecting plate 204 change the lifting point, so that the whole detection device has different postures to adapt to different detection scenes.

[0035] As shown in Figure 4 : when the position of the connecting plate 204 needs to be adjusted, the adjusting bolt is rotated outward, the jack loses the driving force outward, and the sliding of the slider 203 is no longer prevented, at this time, the position of the connecting plate 204 can be adjusted, and when the position is determined, the adjusting bolt is rotated inward, the lower end of the adjusting bolt extrudes the middle of the two jacks, so that the two jacks move outward and are tightly pressed against the inner wall of the sliding groove, and under the action of the pattern for increasing friction, the slider 203 is difficult to slide.

[0036] As shown in Figure 5 , the above device is used for detecting the power transmission tower with the left, middle and right horizontal distribution structure of the power transmission line.

[0037] Before the operation starts, the detection team carries out detailed investigation on the detection site, investigates the line name, tower number, environmental temperature and humidity, weather condition, forms a site investigation information collection table, judges that the detection operation conditions are met, the weather condition is good, there is no thunder, rain, snow and fog, the wind force is less than 10 m / s, and the operation requirements are met, and the site investigation information collection table is formed in the investigation process, and the above information and other related site conditions are recorded in detail.

[0038] Combined with the field survey records, the unmanned aerial vehicle radiographic detection operation construction scheme is prepared, which clearly shows the various links of the detection operation, personnel division of labor, safety measures, and equipment use methods, etc. After strict approval process by relevant departments, it is approved and ready for detection operation.

[0039] The detection personnel comprehensively check the unmanned aerial vehicle equipment and X-ray digital imaging system to ensure that the flight system, control system, and communication system of the unmanned aerial vehicle are all running normally without any fault prompt. The function of the X-ray digital imaging system, including the X-ray machine, detector (including direct conversion detector and indirect conversion detector), and image processing system, is checked, and all parts can work normally.

[0040] The qualified labels of the main detection tools and materials are carefully checked, and the on-site inspection is completed. The insulating rope is protected by a drying box during storage and transportation. Before use, the megohmmeter (2500V-5000V) is used to detect the insulating rope in sections, and the insulation resistance value between electrodes is not less than 700MΩ every 2cm, meeting the requirements for use.

[0041] The electrical conductivity of the X-ray tooling support and shielding device is checked. The resistance value between the farthest points of the X-ray tooling support and shielding device is not greater than 20Ω measured by the multimeter, and the connections are complete.

[0042] The key is used to open the X-ray machine switch, and the operator operates carefully to prevent the key from being lost and the X-ray machine from being bumped. According to the model of the strain clamp, the parameter setting is performed on the XRS-3 menu screen. The strain clamp below NY630 model should use 20 pulse numbers, and above should use 30 pulse numbers. At the same time, the parameters such as Pulses (pulse adjustment), LifePC (total pulse of X-ray machine), Delay (X-ray machine delay start adjustment) are debugged and checked to ensure correct setting.

[0043] The operator tightens the equipment tool screws firmly, assembles the two side frames first to avoid the sliding block falling off, tightens the screws at the marked place to ensure the stability and reliability of the equipment assembly. During the assembly process, the related equipment of the X-ray digital imaging system is reasonably installed and fixed to ensure that it does not shift or loosen during the detection process.

[0044] The right mouse click and left mouse double click Internet Protocol 4 modification settings are performed, the detection required software is opened by clicking OK, and the connection button is clicked after the preparation of the previous setting is completed. After waiting for 20S, the left lower corner prompts to allow collection, and the connection with the X-ray digital imaging system related software is successfully established.

[0045] Check the battery level of the drone, the motor is running normally, no abnormal noise or vibration, firmly and reliably install the radiographic machine and the flat plate on the drone, realize the firm connection between the drone and the X-ray digital imaging device and the insulating rope, and keep the center of gravity stable. After the connection is completed, check the overall connection structure to ensure that it will not loosen or fall off during flight.

[0046] After the drone is turned on, the co-pilot controls the small drone to fly to the detection area to provide the main pilot with a view of the detection area, and turns on the video recording function. The small drone flies stably, the video transmission is clear, and the situation of the power pole tower and the conductor can be clearly seen. The drone carrying the detection device flies to the detection area. During the flight, the operator pays attention to keep the insulating rope clean and dry, and does not directly contact the ground. The co-pilot controls the small drone throughout the process to provide the main pilot with a view of the detection area and guide the precise mounting of the X-ray detection imaging device. During the mounting process, the distance between the drone and the ground conductor is strictly kept not less than 1 meter. The co-pilot and the main pilot keep calling and confirming each key link throughout the operation. The main pilot operates after confirming the instructions.

[0047] When detecting the strain clamp, the radiographic machine reaches the specified position, the aircraft hovers, and the operator pays attention to the wind speed and direction at all times.

[0048] The radiographic machine emits X-rays, which penetrate the strain clamp and the surrounding single and double split conductors and their fittings. The direct conversion detector and the indirect conversion detector simultaneously receive the signals after the X-rays penetrate. For the direct conversion detector, when X-ray photons irradiate the detection material, the photon energy is absorbed by the detection material, directly generating an electrical signal proportional to the X-ray intensity. The indirect conversion detector first absorbs X-ray energy by the fluorescent substance in the IP panel or DR panel, then converts it into visible light, and finally converts the visible light signal into a digital signal through the CR scanner.

[0049] The image processing system receives the electrical signals or digital signals from the detector and performs a series of processing on them. First, the signals are pre-processed, such as amplification, filtering, and correction, to improve signal quality and remove noise interference. Then, through specific algorithms, the processed signals are reconstructed into images that can be observed and analyzed. During image reconstruction, factors such as the geometric parameters of the radiographic machine, the characteristics of the detector, and the physical properties of the measured object are considered to ensure that the reconstructed images accurately reflect the internal structure and defect conditions of the measured object. In addition, the image processing system also has functions such as image enhancement, contrast adjustment, and edge detection to better identify and analyze key parts and possible defects in the measured object.

[0050] After the device is mounted to the predetermined position, the ground personnel remotely control the image acquisition, and the acquired imaging picture is clear and stable, and the image does not have interference defects, incorrect other component images or artifacts. The picture obtained by detecting the same compression fitting can reflect the structure information of all detected parts of the compression fitting, the image blackness and contrast are appropriate, the detected part image is clear, the picture format is saved as RAW format according to the requirement, and the acquired data is processed and stored by the image processing system of the X-ray digital imaging system, so as to facilitate subsequent analysis.

[0051] The pilot controls the unmanned aerial vehicle to carry the X-ray digital imaging device to the tower, the unmanned aerial vehicle descends stably, and lands safely. The on-site personnel disassemble the detection equipment and accessories, recover the unmanned aerial vehicle, the X-ray digital imaging equipment and the insulating rope into respective equipment boxes, and clean up the detection site comprehensively. The site is cleaned up of sundries and garbage, so that the detection site reaches the best state. The pilot notifies the dispatch and related personnel of the first party, and safely evacuates the detection site after receiving the leave instruction.

[0052] Through the above complete detection process, the single and double split conductors and their fittings of the transmission tower with the left, middle and right horizontal distribution structure of the conductors can be comprehensively and accurately detected under the live state, without power-off operation, which greatly improves the power supply reliability of the power system, reduces the inconvenience to users caused by power-off detection, and ensures the accuracy and reliability of the detection results. The strict equipment and tool inspection standard and the accurate detection operation process can ensure the accuracy and reliability of the detection results, and can timely find the possible defects and problems of the conductors and fittings, thereby providing a strong basis for the maintenance and maintenance of the power equipment.

[0053] As shown in Figures 6-8 , the above device is used for detecting the transmission tower with the upper, middle and lower vertical distribution structure of the conductors.

[0054] Before the operation starts, the detection team carefully surveys the site, surveys the line name, tower number, environmental temperature and humidity, weather condition, the environmental temperature and humidity meet the detection operation conditions, the weather is sunny, there is no thunder, rain, snow and fog weather, the wind force is less than 10 m / s, which meets the operation requirements, and the site survey information is recorded in the information acquisition table.

[0055] According to the site survey result, a unmanned aerial vehicle radiation detection operation construction scheme is prepared, the scheme covers the detection process, personnel arrangement, safety measures and equipment operation details, and successfully passes the approval process.

[0056] The inspector checks the unmanned aerial vehicle equipment and the X-ray digital imaging system to confirm that each system of the unmanned aerial vehicle is operating normally, that the X-ray digital imaging system is functioning properly, that the X-ray machine, the detector (including direct conversion and indirect conversion detectors), and the image processing system are functioning properly, that the main detection tools and materials are checked for qualified labels, and that the on-site inspection is completed. The insulating rope is stored and transported in a drying box, and before use, it is tested in sections using a megohmmeter (2500V-5000V) to measure the insulation resistance between electrodes every 2 cm, which should not be less than 700MΩ. The electrical conductivity of the X-ray tool support and shielding device is checked, and the resistance between the farthest points is measured using a multimeter, which should not be greater than 20Ω. The connections are good.

[0057] The X-ray machine switch is opened with a key, and the operator operates it carefully to prevent the key from being lost and the X-ray machine from being bumped. For the strain clamp model, the parameters are set on the XRS-3 menu screen. Assuming that the strain clamp is NY630 or higher, 30 pulses are selected, and the Pulses, LifePC, Delay, and other parameters are adjusted and checked.

[0058] The equipment tool screws are tightly screwed, the two side frames are assembled first to prevent the slider from falling off, the screws are tightened at the marked positions, and the X-ray digital imaging system related equipment is installed and fixed well. The equipment assembly condition is checked to ensure its stability and prevent loosening during detection.

Successfully establish a software connection.

[0060] Check that the unmanned aerial vehicle battery has sufficient power and that the motor is running normally without any abnormal noise. The X-ray machine and the flat panel are securely installed on the unmanned aerial vehicle to achieve a secure connection between the unmanned aerial vehicle and the X-ray digital imaging equipment and the insulating rope, maintain stable center of gravity, and ensure flight safety.

[0061] After the unmanned aerial vehicle is turned on, the co-pilot controls the small unmanned aerial vehicle to fly to the detection area to provide the main pilot with a view of the detection area and starts the video recording function. The small unmanned aerial vehicle flies stably, the video transmission is clear, and the transmission tower and conductor can be seen. The unmanned aerial vehicle carrying the detection equipment flies to the detection area, keeping the insulating rope clean, dry, and not touching the ground. The co-pilot controls the small unmanned aerial vehicle to provide a visual guide to the mounting, ensuring that the distance between the unmanned aerial vehicle and the ground conductor is not less than 1 meter. During the operation, the co-pilot and the main pilot maintain call and confirmation.

[0062] When detecting the conductors and fittings of the upper, middle, and lower phases, the X-ray machine reaches the specified position, the aircraft hovers, and the wind speed and direction are noted. The X-ray machine emits X-rays, which penetrate the conductors and fittings of the upper, middle, and lower phases and the surrounding related components.

[0063] The direct conversion detector and the indirect conversion detector simultaneously receive the signal after the ray penetrates, the direct conversion detector directly converts the X-ray photon energy into an electrical signal, the principle is that the photon interacts with the atoms in the detection material, electron transition is generated, and an electrical signal proportional to the X-ray intensity is formed, in the indirect conversion detector, the fluorescent substance of the IP panel or the DR panel converts the absorbed X-ray energy into visible light, and then the CR scanner converts the visible light signal into a digital signal.

[0064] The image processing system receives the electrical signal or the digital signal from the detector, first performs pre-processing operations such as amplification, filtering, correction, etc. on the signal to improve the signal quality and remove noise interference, for example, by setting appropriate amplification and filtering parameters, remove high-frequency noise and low-frequency drift in the signal, then according to the geometric parameters of the ray machine, the characteristics of the detector and the physical properties of the measured object and other factors, a specific algorithm is used to reconstruct the processed signal and convert it into an image that can be observed and analyzed, in the image reconstruction process, considering the distance, angle and resolution of the detector between the ray machine and the measured object, etc. Factors to ensure that the reconstructed image can accurately reflect the internal structure and defect situation of the measured object, in addition, the image processing system also has image enhancement, contrast adjustment, edge detection and other functions, in order to better identify and analyze the key parts and possible defects in the measured object.

[0065] After the equipment is mounted to the predetermined position, the ground personnel remotely collect images, the collected images are clear and stable, without interference, other component images, artifacts that affect defect identification or measurement, for the same picture of the compression fitting, all the structure information of the detected parts can be reflected, the image blackness and contrast are appropriate, and the format is saved as RAW format, the data is processed and stored through the image processing system.
