Description

Technical Field

[0001] This invention relates to the field of X-ray flaw detection equipment technology, specifically to an X-ray flaw detection device for a four-split conductor of a power transmission line mounted on a drone. Background Technology

[0002] In the operation of power transmission networks, the connecting hardware (such as suspension clamps and tension clamps) of four-split conductors (power transmission structures composed of four parallel conductors connected by spacers) is prone to cracking due to long-term stress, and needs to be regularly inspected with X-rays to prevent breakage accidents.

[0003] Traditional manual X-ray inspection of power lines requires personnel to climb the tower. During the operation, the close proximity of the personnel to the conductors necessitates a power outage to prevent electric shock. This makes scheduling and coordinating power outages difficult and poses a high risk to the power grid during outages. Furthermore, the operation requires multiple people to climb the tower, posing safety risks such as falls from heights, and also results in low work efficiency.

[0004] With the rapid development of drone technology, drones equipped with flaw detection robots can achieve efficient and accurate inspection of power transmission lines. By mounting a lightweight X-ray source and a digital imaging plate, the drone can precisely hover beside the fittings, allowing the X-rays to penetrate the internal structure of the fittings, and the imaging plate to capture images of defects. For example, the inspection device in Reference 1.

[0005] Reference 1: Chinese patent document with publication number CN117446222A.

[0006] Reference 1 describes a live detection device and method for tension clamps of transmission lines based on dual unmanned aerial vehicles (UAVs). The detection device includes dual UAVs, a detection unit, a position adjustment component, and an imaging plate. The dual UAVs are a master unit and a slave unit, respectively. The imaging plate is located on the slave unit, the position adjustment component is located on the master unit, and the detection unit is located on the position adjustment component. The position adjustment component is used to adjust the position of the detection unit.

[0007] When performing high-altitude flaw detection, this type of dual-drone equipment requires the drones to remain suspended in the air at all times, which places high demands on the operators. Furthermore, in strong winds, it is difficult for the drones to maintain stable hovering. In addition, heavy-duty drones need to maintain a certain safe distance (to prevent rotor airflow from disturbing the conductors), which may lead to attenuation of X-ray intensity, insufficient particle reception on the imaging plate, and a decrease in the detection rate of microcracks in hardware.

[0008] Existing technologies also document devices capable of performing non-destructive testing on power transmission lines via drones, such as the testing device described in Reference 2.

[0009] Reference 2: Chinese patent document with publication number CN119224014A.

[0010] Reference 2 describes a live X-ray digital imaging detection device for tension clamps of transmission lines, including an X-ray machine, an imaging plate that works with the X-ray machine, and a carrier drone. The lower end of the drone is equipped with an equipment frame, and a walking mechanism is installed on the equipment frame. The bottom of the carrier drone is equipped with landing gear, a camera mechanism, and a power supply. The walking mechanism includes a dust cover, grooved pulleys, and a cleaning plate. The grooved pulleys and the cleaning plate are installed inside the dust cover and rotatably connected to it. The walking mechanism is movably connected to the equipment frame.

[0011] This inspection device can perform X-ray inspection on single-split conductors. However, when inspecting four-split conductors, the device needs to pass through the gaps between the conductors, meaning it lacks the capability to inspect four-split conductors. Furthermore, existing inspection devices for four-split conductors are all self-propelled, resulting in complex structures. Therefore, the applicant proposes a non-walking X-ray flaw detection device for four-split conductors in power transmission lines. Summary of the Invention

[0057] To better understand the present invention, the following embodiments further illustrate the content of the present invention, but the content of the present invention is not limited to the following embodiments.

[0058] like Figure 1-7 As shown: An X-ray flaw detection device for a four-split conductor of a power transmission line mounted on a drone includes a lifting body 1, an upper imaging plate assembly 2, a lower imaging plate assembly 3, and an X-ray machine assembly 4.

[0059] The lifting body 1 includes a mounting plate 101, a movable plate 102, and a lifting drive. The movable plate 102 is located below the mounting plate 101 and can move vertically via the lifting drive.

[0060] The upper imaging plate assembly 2 includes a rotary driver and two upper imaging plates. The two upper imaging plates are respectively disposed on both sides of the mounting plate 101, and the top of the upper imaging plates is hinged to the top of the mounting plate 101 via a rotary shaft 6. The rotary driver can drive the two upper imaging plates to expand or contract simultaneously.

[0061] The lower imaging plate assembly 3 includes a rotary driver and two lower imaging plates. The two lower imaging plates are respectively disposed on both sides of the movable plate 102, and the bottom of the lower imaging plates is hinged to the bottom of the movable plate 102 through a rotary shaft 6. The rotary driver can drive the two lower imaging plates to expand or contract simultaneously.

[0062] X-ray machine assembly 4 includes an X-ray machine and a flip drive. The X-ray machine is mounted on the bottom of the mounting plate 101 via a rotating component. The X-ray machine can be flipped under the drive of the flip drive, and its flip trajectory plane is perpendicular to the plane of the mounting plate 101.

[0063] Two rotating shaft seats 5 are provided on the top of each of the two sides of the mounting plate 101. A rotating shaft 6 is passed between the two rotating shaft seats 5. The rotating shaft 6 is rotated and supported by the rotating shaft seats 5. The upper imaging plate is fixedly sleeved on the shaft of the rotating shaft 6 located on the support of the two rotating shaft seats 5.

[0064] Two rotating shaft seats 5 are provided on the bottom of both sides of the movable plate 102. A rotating shaft 6 is inserted between the two rotating shaft seats 5. The rotating shaft 6 is rotated and supported by the rotating shaft seats 5. The lower imaging plate is fixedly sleeved on the shaft of the rotating shaft 6 located on the support of the two rotating shaft seats 5.

[0065] Thus, the upper and lower imaging plates can be flexibly flipped around the axis by the cooperation of the rotating shaft 6 and the rotating shaft seat 5.

[0066] Both ends of the rotating shaft 6 are equipped with turntables 7. L-shaped drive rods 8 are arranged on the circumference of the turntables 7. Each L-shaped drive rod 8 consists of a perpendicular connecting part and a driving part, which are fixedly connected to the turntables 7 via the connecting part, which is arranged radially along the turntables 7. The rotary actuator includes a power source and a drive component 9. The drive component 9 consists of two drive plates 901 and a linkage plate 902 connecting the two drive plates 901. The power source can drive the two drive plates 901 to move up or down simultaneously via the linkage plate 902. The two drive plates 901 are respectively located at both ends of the rotating shaft 6. Each drive plate 901 has an elongated through hole 903, the length of which is perpendicular to the mounting plate 101 / movable plate 102. The driving parts of the two L-shaped drive rods 8 located on the same side pass through the through holes of the corresponding drive plates 901. The driving part of the L-shaped drive rod 8 has a cylindrical structure, and its end is equipped with an anti-detachment head 904.

[0067] For the upper imaging plate assembly 2, when the power source drives the linkage plate 902, which in turn moves the two drive plates 901 synchronously downward to their extreme positions, the sidewall of the through hole 903 pushes the drive part of the L-shaped drive rod 8 to move, thereby driving the turntable 7 and the rotating shaft 6 to rotate, ultimately causing the imaging plate to unfold into its working state (i.e., the imaging plate body is in the detection position). Conversely, when the drive plate 901 moves upward to its extreme position, the through hole 903 pushes the drive part in the opposite direction, driving the turntable 7 and the rotating shaft 6 to rotate in the opposite direction, causing the imaging plate to retract to its initial closed state (facilitating equipment movement or storage). During this process, the anti-detachment head effectively prevents the drive part from accidentally detaching from the through hole 903.

[0068] There are two specific structural forms of the power source:

[0069] The first type: The power source is an electric push rod. The imaging plate has a cavity inside. The electric push rod is vertically installed inside the imaging plate, and its telescopic rod is connected to the horizontal part of the linkage plate 902.

[0070] The second type: The power source includes a drive motor, a reducer and a transmission assembly. The drive motor is installed inside the imaging plate. The transmission assembly includes a rack and a transmission gear. The output shaft of the drive motor is connected to the reducer. The transmission gear is sleeved on the output shaft of the reducer. The rack is vertically installed inside the imaging plate through a slide rail. The lower end of the rack meshes with the transmission gear, and the upper end of the rack is connected to the horizontal part of the linkage plate 902.

[0071] The core mechanism of both structures is that the linear output of the power source (electric push rod direct drive or motor-gear rack conversion) acts on the horizontal part of the U-shaped linkage plate, so that the linkage plate drives the two drive plates to achieve precise synchronous up and down displacement. Then, through the cooperation of the through hole 903 and the L-shaped drive rod 8, the linear motion is converted into the rotational motion of the rotating shaft 4, which ultimately drives the opening and closing of the imaging plate.

[0072] The upper and lower imaging plates are provided with grooves for accommodating the imaging plate body, which is securely housed within these grooves. To protect the equipment from impact damage during rotation and operation, rubber protective bars are provided on the outer edges of the upper and lower imaging plates.

[0073] The linkage plate 902 is a U-shaped plate consisting of a horizontal part and two vertical parts, with its opening facing upwards and disposed in the cavity of the substrate. The two horizontal parts of the linkage plate 902 are respectively connected to two drive plates 901.

[0074] The mounting plate 101 has a mounting slot for mounting the X-ray machine assembly 4 at the lower middle position. Two flip shaft seats 10 are symmetrically arranged on the two inner walls of the mounting slot. Flip shafts 11 are respectively inserted through the flip shaft seats 10. The X-ray machine assembly 4 is placed in the mounting slot and fixedly connected to the two flip shafts 11. One of the flip shafts 11 is connected to a rotary driver.

[0075] The flip drive includes a drive motor, a reducer, and a coupling built into the mounting plate 101. The drive motor is connected to the flip shaft 11 via the reducer and coupling.

[0076] The lifting drive includes a lifting winch and a hoisting rope 12. The lifting winch is built into the cavity of the mounting plate 101. One end of the hoisting rope 12 is connected to the output shaft of the lifting winch, and the other end is connected to the upper surface of the movable plate 102.

[0077] The upper end face of the movable plate 102 is provided with a plug 13, and the lower end face of the mounting plate 101 is provided with a slot 14 that mates with the plug 13.

[0078] The insertion end of the plug 13 has a guide portion with a chamfered angle greater than 45°. A guide structure is provided at the lower entrance of the slot 14, comprising a flared tapered guide portion extending outward from the inner wall of the slot 14. A flexible layer, made of rubber, is provided at the tip of the insertion end of the plug 13.

[0079] The plug 13 of the movable plate 102 and the slot 14 of the mounting plate 101 are fitted with an introductory chamfer and a flared tapered guide part. Combined with the rubber flexible layer at the end of the plug, the movable plate and the mounting plate can be quickly and accurately connected, reducing the impact of mechanical vibration during high-altitude operations, ensuring the stability of the X-ray penetration path, and thus improving the detection rate of microcracks in hardware.

[0080] like Figure 8 As shown: The UAV, carrying a mounting plate via a hook, flies above the four-split conductor. The operator, through the ground control system, unfolds the two upper imaging plates on the mounting plate and then lowers the mounting plate, placing the two upper imaging plates on the two upper conductors. A drive motor rotates the X-ray machine assembly, aligning the X-ray emission direction with the suspension clamps or tension clamps of the two upper conductors. Simultaneously, the imaging plate carried by the movable plate receives X-ray signals penetrating the fittings, completing the inspection of the fittings of the two upper conductors. Then, a winch motor lowers the movable plate, completely separating it from the mounting plate. When the movable plate is below the two lower conductors, the operator, through the ground control system, unfolds the two lower imaging plates on the mounting plate. The movable plate is then raised until the two lower imaging plates contact the fittings of the two lower conductors. A drive motor rotates the X-ray machine assembly, aligning the X-ray emission direction with the suspension clamps or tension clamps of the two lower conductors. The imaging plate carried by the movable plate simultaneously receives X-ray signals penetrating the fittings, completing the inspection of the fittings of the two lower conductors. After the test is completed, the control system retracts the two lower imaging plates on the mounting plate, the winch motor winds up the hoisting rope, the movable plate rises to the initial position, the plug and slot reconnect, and the drone carrying the equipment returns to the ground.

[0081] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
