Description

Technical Field

[0001] This utility model relates to the field of X-ray flaw detection equipment technology, specifically to an imaging plate assembly for X-ray flaw detection equipment for four-split conductors of power transmission lines. 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 transmission lines, which utilizes two deployable and retractable imaging plate assemblies.

[0046] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0047] like Figure 1-5 As shown: An imaging plate assembly of an X-ray flaw detection device for a four-split conductor of a power transmission line includes a base plate 1, two flip-wing plates 2, and a driving assembly 3 for driving the two flip-wing plates 2 to flip simultaneously. The imaging plate body is disposed on the flip-wing plates 2.

[0048] Two flip-wing plates 2 are symmetrically arranged on both sides of the substrate 1. The top of the flip-wing plates 2 is hinged to the top of the substrate 1 through a pivot 4. Two bearing seats 5 are provided on the top of both sides of the substrate 1. The pivot 4 passes through the two bearing seats 5 and is rotated and supported by the bearing seats 5. The flip-wing plates 2 are fixedly sleeved on the pivot 4 located on the shaft of the two bearing seats 5.

[0049] The base plate 1 has two bearing seats 5 on each of its two sides. The rotating shaft 4 passes through the two bearing seats 5 to form a rotating support structure. The flip wing plate 2 is fixedly sleeved on the part of the shaft 4 that passes through the shaft between the two bearing seats. Thus, the flexible flipping movement of the flip wing plate 2 around the axis is realized through the cooperation of the rotating shaft 4 and the bearing seats 5.

[0050] Both ends of the rotating shaft 4 are provided with turntables 6. L-shaped drive rods 7 are provided on the circumference of the turntables 6. The L-shaped drive rods 7 are composed of mutually perpendicular connecting parts and driving parts. They are fixedly connected to the turntables 6 through the connecting parts, and the connecting parts are arranged along the radial direction of the turntables 6.

[0051] The drive assembly 3 includes a power source and a drive component. The drive component consists of two drive plates 301 and a linkage plate 302 connecting the two drive plates 301. The linkage plate 302 is a U-shaped plate composed of a horizontal part and two vertical parts, with its opening facing upwards and set in a basic cavity. The two horizontal parts of the linkage plate 302 are respectively connected to the two drive plates 301.

[0052] The power source can drive the two drive plates 301 to move up or down simultaneously via the linkage plate 302. The two drive plates 301 are respectively located at both ends of the rotating shaft 4. The drive plates 301 are provided with two through holes 303. The length direction of the through holes 303 is perpendicular to the base plate 1. The driving parts of the two L-shaped drive rods 7 located on the same side are respectively placed in the two through holes 303. The driving part of the L-shaped drive rod 7 is a cylindrical structure, and its end is provided with an anti-detachment head 8.

[0053] When the power source drives the linkage plate 302, which in turn moves the two drive plates 301 synchronously downwards to their extreme positions, the sidewall of the through hole 303 pushes the drive part of the L-shaped drive rod 7 to move, thereby driving the turntable 6 and the rotating shaft 4 to rotate, ultimately causing the flip wing plate 2 to unfold into the working state (i.e., the imaging plate body is in the detection position). Conversely, when the drive plate 301 moves upwards to its extreme position, the through hole 303 pushes the drive part in the opposite direction, driving the turntable 6 and the rotating shaft 4 to rotate in the opposite direction, causing the flip wing plate 2 to retract to its initial closed state (facilitating equipment movement or storage). During this process, the anti-detachment head 8 effectively prevents the drive part from accidentally detaching from the through hole 303.

[0054] There are two specific structural forms of the power source:

[0055] The first type: The power source is an electric push rod. The interior of the base plate 1 is provided with a cavity. The electric push rod is vertically installed in the base plate 1, and its telescopic rod is connected to the horizontal part of the linkage plate 302.

[0056] The second type: The power source includes a drive motor, a reducer and a transmission assembly. The drive motor is installed in the base plate 1. 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 in the base plate 1 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 302.

[0057] 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 303 and the L-shaped drive rod 7, the linear motion is converted into the rotational motion of the rotating shaft 4, which ultimately drives the opening and closing of the flip wing plate 2.

[0058] The flip-up wing plate 2 has a groove on its inner side facing the base plate 1 to accommodate the imaging plate body, which is securely housed within the groove. To protect the equipment from impact damage during flipping and operation, rubber protective bars are provided on the outer edge of the flip-up wing plate 2.

[0059] like Figure 6 As shown, this utility model uses a U-shaped linkage plate to connect the two drive plates, and with a single power source, it realizes the synchronous deployment and retraction of the two flip-wing plates. When the two flip-wing plates are deployed, they can be placed on two parallel split conductors, and with the help of an X-ray machine, the non-destructive testing of the power transmission line hardware can be completed.

[0060] The specific embodiments of this utility model have been described above. It should be understood that this utility model 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 substantive content of this utility model.
