Description

Technical Field

[0001] This utility model relates to the field of X-ray flaw detection equipment technology, specifically to an X-ray inspection device for a four-split transmission line. 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. Examples include the inspection devices described in references 1 and 2.

[0005] Reference 1: Chinese patent document with publication number CN118067750A.

[0006] Reference 1 describes an X-ray inspection device and method for tension clamps of four-split conductors in transmission lines. The device includes a frame with space for accommodating the four-split conductors. The frame is equipped with multiple pulleys for contacting the four-split conductors and supporting the frame. At least one locking mechanism is provided on the frame to limit the relative position of the pulleys and the conductors. An X-ray machine and a detector for receiving and imaging X-rays emitted by the machine are respectively mounted on opposite sides of the frame. A control unit receives control terminal signals and controls the detector's vertical movement along the Z-axis and the deflection of the X-ray machine. This invention solves the problem of imaging interference between transmission line fittings in the inspection of multi-split transmission lines. This invention employs single-sided transmission line fitting inspection, avoiding the problem of overlapping fitting images present in existing suspended inspection methods.

[0007] Reference 2: Chinese patent document with publication number CN119787177A.

[0008] Reference 2 describes a non-destructive testing robot for four-split power transmission line conductors based on an unmanned aerial vehicle (UAV). The robot features a rectangular frame capable of being erected and moved on the split conductors. Imaging components and X-ray machines are located at both ends of the rectangular frame, and a housing is situated in the middle. Vertically sliding drive frames are located on both sides of the rectangular frame along its direction of movement. Rollers are located at the bottom of the drive frames to allow movement on the split conductors. The drive frames also include expansion and transmission components. This design addresses the problem in existing four-split conductor X-ray camera inspection robots that are easily affected by environmental factors and prone to detachment from the four-split conductors, leading to equipment damage from falls.

[0009] The aforementioned testing equipment can all perform X-ray inspection of four-split conductor fittings. However, the structure of these testing equipment is that of self-propelled devices, and the overall structure of the equipment is relatively complex. Based on this, the applicant proposes a non-walking X-ray inspection device for four-split transmission lines. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] likeFigures 1-6 As shown: An X-ray inspection device for a four-split transmission line includes a body 1, a mounting base 2, an imaging plate assembly 3, and an X-ray machine assembly 4.

[0024] The fuselage 1 is a rectangular plate structure. Two rotating shaft seats 101 are provided on the top of both sides of the fuselage 1. A rotating shaft is inserted between the two rotating shaft seats 101, and the rotating shaft is rotated and supported by the rotating shaft seats 101.

[0025] The imaging plate assembly 3 includes a rotary driver, a first imaging plate 301 and a second imaging plate 302. Both the first imaging plate 301 and the second imaging plate 302 include a base plate and an imaging plate mounted on the base plate. The first imaging plate 301 and the second imaging plate 302 are respectively fixedly sleeved on two rotating shafts on both sides through their base plates. The rotary driver can drive the first imaging plate 301 and the second imaging plate 302 to expand or contract simultaneously.

[0026] X-ray machine assembly 4 includes an X-ray machine and a flip drive. The X-ray machine is rotatably mounted on the lower part of the machine body 1. 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 machine body 1.

[0027] The mounting base 2 has an X-shaped structure. The mounting base 2 has a pair of downwardly extending lower support legs 201 and a pair of upwardly extending upper support legs 202. Two mounting bases 2 are provided at the top and bottom of the body 1. The mounting base 2 is fixed to the body 1 by its two lower support legs 201.

[0028] The included angle between the two lower support legs 201 is smaller than the included angle between the two upper support legs 202. A support base is provided at the end of each upper support leg 202. The support base is a flat plate structure, and the support bases of the two upper support legs 202 located at the same end are in the same plane.

[0029] Both ends of the rotating shaft are provided with turntables 5. L-shaped drive rods 6 are provided on the circumference of the turntables 5. The L-shaped drive rods 6 are composed of mutually perpendicular connecting parts and drive parts. They are fixedly connected to the turntables 5 through the connecting parts, and the connecting parts are arranged radially along the turntables 5. The rotary drive includes a power source and a drive component 7. The drive component 7 is composed of two drive plates 701 and a linkage plate 702 connecting the two drive plates 701. The linkage plate 702 is a U-shaped plate body composed of a horizontal part and two vertical parts. Its opening faces upward and is set in the cavity of the body 1. The two horizontal parts of the linkage plate 702 are respectively connected to the two drive plates 701.

[0030] The power source can drive two drive plates 701 to move up or down simultaneously via the linkage plate 702. The two drive plates 701 are respectively located at both ends of the rotating shaft. Each drive plate 701 has an elongated through hole 703, the length of which is perpendicular to the body 1. The drive parts of the two L-shaped drive rods 6 located on the same side pass through the through holes of the corresponding drive plates 701. The drive parts of the L-shaped drive rods 6 are cylindrical, and their ends are equipped with anti-detachment heads 8.

[0031] An electric linear actuator is an actuator that converts electrical energy into linear reciprocating motion. Its core function is to drive the extension and retraction of the actuator via a motor, thereby outputting thrust or pull force. When the control system issues an action command, the motor rotates forward, the reduction mechanism reduces the speed and amplifies the torque, the screw rotates synchronously, and the nut moves along the screw axis, pushing the actuator to extend (or retract). The thrust is transmitted to the two drive plates 701 through the linkage plate 702, ultimately achieving synchronous upward or downward movement of the drive plates.

[0032] A longitudinally extending mounting groove is integrally formed at the lower center of the machine body 1. A pair of flip shaft seats are symmetrically fixed on the left and right inner walls of the mounting groove. Each flip shaft seat rotatably supports a flip shaft. The X-ray machine is housed in the mounting groove, and its two sides are rigidly fixed to the flip shafts respectively.

[0033] At least one of the tilting shafts is configured as a drive shaft, which is connected to a power source inside the fuselage via a tilting driver. The tilting driver includes: a drive motor (servo motor or stepper motor) whose body is completely embedded in the fuselage's housing structure; a reducer whose input end is coaxially connected to the output shaft of the drive motor; and a coupling whose input end is connected to the output end of the reducer, and whose output end is torsionally connected to the drive shaft.

[0034] When the drive motor is powered on and rotates, the torque is transmitted sequentially through the reducer, coupling, and drive shaft, thereby driving the X-ray machine to controllably rotate between the stowed and unfolded positions around the common axis of the rotation shaft. To meet the requirements of precise detection, an encoder (such as an absolute encoder) can be installed at the end of the rotation shaft to provide real-time feedback of the rotation angle signal to the control system. The control system adjusts the pulse frequency or voltage of the drive motor according to the target angle to achieve closed-loop control and ensure the accuracy of the rotation angle.

[0035] like Figure 7As shown: A hoisting rod is inserted between two bracket bases on the top of the testing device, with anti-detachment rods at both ends. The drone is connected to the hoisting rod via a sling and flies the testing device above the four-split conductor (orthogonal mounting). The operator uses the ground control system to unfold the two imaging plates on the testing device, then controls the device to descend, placing the two imaging plates on the two upper conductors. The 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 plates carried by the movable plate receive X-ray signals penetrating the fittings, completing the testing of the fittings of the two upper conductors. After the testing is completed, the drone returns to the ground with the equipment.

[0036] like Figure 7 As shown: The testing device is inverted, and a hoisting rod is inserted between the two bracket bases at the bottom of the device. Anti-detachment rods are installed at both ends of the hoisting rod. The drone is connected to the hoisting rod via a sling and carries the testing device to a position above the four-split conductors, between the left and right conductors (inverted). The operator lowers the testing device to below the two lower conductors via the ground control system, then controls the two imaging plates to unfold. The testing device is then raised until the two imaging plates contact the fittings of the two lower conductors. The 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 plates carried by the movable plate simultaneously receive the X-ray signals penetrating the fittings, completing the inspection of the fittings of the two lower conductors. After inspection, the control system retracts the two imaging plates on the testing device, and the drone returns to the ground with the equipment.

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.
