Description

Technical Field

[0001] The utility model relates to the technical field of X-ray detection, in particular to the technical field of a device for detecting physical structural defects of a power transmission line based on X-rays, and specifically to an X-ray detection device for a four-split high-voltage transmission line. Background Art

[0002] Strain clamps (tensi on clamp, stra incl amp, dead-end clamp) refer to hardware used to fix conductors to withstand conductor tension and hang the conductors on tension strings or poles. Strain clamps can be roughly divided into two categories according to their structure and installation conditions. The first category: The strain clamp must withstand the full tensile force of the conductor or lightning conductor, and the clamp gripping force must not be less than 90 of the rated tensile force of the installed conductor or lightning conductor, but it does not serve as a conductor. This type of clamp can also be removed after the conductor is installed and used separately. This type of clamp includes bolt-type strain clamps and wedge-type strain clamps. The second category: In addition to bearing the full tensile force of the conductor or lightning conductor, the strain clamp also serves as a conductor. Therefore, once this type of clamp is installed, it cannot be disassembled again, and is also called a dead-end clamp. Since it is a conductor, the installation of the clamp must comply with the provisions of the relevant installation operating procedures and be carried out carefully.

[0003] Since high-voltage transmission lines often span mountains and valleys, have large spans and heavy weight, the main forces pulling the large-span transmission lines are concentrated on the tension clamps. Therefore, the structural strength of the tension clamps is crucial to the transmission reliability of high-voltage transmission lines.

[0004] At present, the objects for strain clamp defect detection are basically in service, so they have a higher voltage. This environment has greatly limited the means of detection. In addition, the defects of strain clamps are often internal defects caused by crimping and fatigue. Therefore, in the prior art, X-ray detection is mostly used for high-altitude, high-voltage environment monitoring. The applicant has long been committed to the research and development and practice of high-voltage transmission line detection technology. In the prior art, although there are many detection devices and methods, due to the limitations of the use scenarios, most of the detection devices have heavy weight and low compatibility, especially when detecting multi-split lines, it is easy to have imaging occlusion between the wires. For details, please refer to the automatic flipping device for unmanned aerial vehicle X-ray detection of multi-split conductor tension clamps disclosed in publication number CN218726782U, and the detection device developed by the applicant in the early stage, refer to the obstacle-crossing robot for live X-ray detection and cleaning of power transmission lines provided by publication number CN112787265A, and the equipotential live X-ray detection device for overhead line fittings provided by announcement number CN211528251 U. The above-mentioned prior arts all adopt suspension detection, and the detection angle of this method is immutable. In addition, the suspension design can only detect a single transmission line, and it is impossible to change the angle and perform the same-machine detection on different transmission lines.

[0042] Embodiment 1:

[0043] This embodiment provides an X-ray detection device for a four-split high-voltage transmission line. Figure 1-Figure 9As shown, it includes a frame 1, which includes an inverted U-shaped structure for being installed across four-split high-voltage transmission lines, and an X-ray machine 7 and a detector 8 are respectively arranged on opposite sides of the inverted U-shaped structure, the X-ray machine 7 is rotatably installed on the frame 1 along the X-axis, and the detector 8 is lifted and lowered on the frame 1 along the Z-axis, and the frame 1 is also provided with a central processing unit 4 for receiving control signals and controlling the switches of the X-ray machine 7 and the detector 8; the X-ray machine 7 is driven and connected to the frame 1 through a deflection mechanism 12, and the detector 8 is driven and connected to the frame 1 through a lifting mechanism 9; the deflection mechanism 12 and the lifting mechanism 9 are both electrically connected to the central processing unit 4; wherein, the direction of the transmission line is the X-axis direction, the vertical direction is the Z-axis direction, and the direction perpendicular to the surface of the detector 8 is the Y-axis direction.

[0044] Working principle and structure description:

[0045] The frame 1 is the main force-bearing skeleton structure of the detection device, which is used to install the accessories required for X-ray detection, including the X-ray machine 7, the detector 8, the central processing unit 4 and other auxiliary components. The frame 1 itself is a fixed mechanical structure, which is used to be installed across the four-split transmission line. The overall shape is an inverted U, so that the center of gravity is low and it is stable when installed on the four-split transmission line. The frame 1 does not have a fixed structural setting, as long as it can meet the above requirements, see Figure 1 and Figure 7 Two different structures of the frame 1 are shown respectively.

[0046] The X-ray machine 7 and the detector 8 are relatively installed on the opposite sides of the frame 1, and are used to transmit and receive X-rays respectively, so as to obtain an X-ray image of the object being detected. The working principle is the same as that of the existing X-ray equipment, and the working principle is not described in detail. This embodiment mainly describes the differences from the existing power transmission line hardware detection device, which specifically includes:

[0047] See also Figure 1The X-ray machine 7 shown can rotate along the X-axis, that is, the X-ray range can be adjusted in pitch to adapt to the detector 8 moving up and down and enable the detector 8 to receive the X-ray residue from the X-ray machine 7 at the upper and lower limit positions. There are two on one side of the four-split transmission line, one on the top and one on the bottom. When detecting the tension clamps on the transmission lines at different positions, the pitch angle of the X-ray machine 7 and the position of the detector 8 are different. Taking the detection of the upper tension clamp as an example, the X-ray machine 7 is at an upward angle and the detector 8 is at the upper limit position; conversely, when detecting the lower tension clamp, the X-ray machine 7 is at a downward angle and the detector 8 is at the lower limit position. By setting the X-ray machine 7 between the upper and lower transmission lines, the tension clamp on any transmission line can be detected by deflection, and the problem of image interference caused by multiple detection objects or non-detection objects can be fundamentally avoided in physical space. At the same time, the detection device provided by this embodiment can realize the detection of two tension clamps at the same detection position without moving, reducing the adjustment work during the detection process and making it more efficient.

[0048] Embodiment 2:

[0049] This embodiment further optimizes the structure on the basis of the embodiment 1. Specifically, in order to improve the stability of the detection device during the detection process, this embodiment installs at least one locking mechanism 6 for clamping or loosening the transmission line on the frame 1 at a position in contact with the transmission line. Figure 3 and Figure 4 As shown, the locking mechanism 6 includes a rotating shaft that can provide torque, a worm 63 is arranged on the rotating shaft, and the worm 63 is drivingly connected to a worm wheel 641 arranged at one end of a movable clamp 64. The center position of the worm wheel 641 is hinged to the frame 1 through an axle pin, and the worm 63 drives the movable clamp 64 to deflect in a positive / reverse direction to form a clamping / loosening structure with the static clamp fixedly installed on the frame 1. In this embodiment, the rotating shaft is driven in a direct drive manner, for example, the output shaft of a servo motor is connected to the rotating shaft, and the rotating shaft is directly driven to drive the worm wheel 641 to deflect. However, this method must ensure that the torque provided by the servo motor can achieve effective clamping.

[0050] In order to provide greater torque, this embodiment also adds a speed reduction mechanism, see Figure 4 As shown, the rotating shaft is a driven rotating shaft B62, and the other end of the rotating shaft B62 is drivingly connected to the rotating shaft A61 as a driving shaft through a reduction mechanism. The reduction mechanism is any one of a gear set structure, a sprocket chain structure, and a belt pulley structure, and the reduction direction is consistent with the driving direction. Figure 4As shown, by driving the shaft A61 and the shaft B62, the effect of deceleration and torque increase can be achieved through different reduction ratios, so that the clamping force is greater and more reliable. In order to better maintain the stability of clamping, the movable clamp 64 is used to contact one side of the tension clamp, that is, the inner side is provided with an anti-slip structure 642, such as a convex structure of rubber material, or a rubber anti-slip layer attached or bonded to the inner side of the movable clamp 64, to avoid the problem of insufficient clamping stability caused by insufficient friction between metal structures and insufficient contact area.

[0051] Embodiment 3:

[0052] This embodiment optimizes the setting of the lifting mechanism 9 based on any of the above embodiments. The lifting mechanism 9 adopts any one of a belt and pulley transmission mechanism, a sprocket and chain transmission mechanism, a winch mechanism, a screw thread sleeve transmission mechanism and an electric push cylinder telescopic mechanism.

[0053] See the instruction manual Figure 5 , Fig. 9 As shown, the lifting mechanism 9 adopts a belt and pulley transmission mechanism, specifically including two pulley units symmetrically installed on the frame 1, the pulley unit includes a driving wheel 91 and a driven wheel 94 fixedly arranged on the frame 1, a belt 92 tightly sleeved and installed between the driving wheel 91 and the driven wheel 94, and a clamping seat 93 for connecting the belt 92 and the detector 8. In this embodiment, the driving wheel 91 drives the belt 92 to rotate forward / reverse, and the clamping seat 93 drives the detector 8 to move up and down. The advantage of this method is that it is easy to install and adjust.

[0054] This embodiment also provides another structure, see Figure 7 As shown, the lifting mechanism 9 adopts a winch mechanism, which includes a wire reel 97 arranged on the frame 1, and a guide rail 95 fixedly arranged on the frame 1 along the Z axis and located on both sides of the detector 8. A slide 96 fixedly connected to the detector 8 is slidably mounted on any guide rail 95, and a wire clamping seat 81 for pulling the wire arranged on the top of the detector 8 is wound on the wire reel 97. The working principle of the winch mechanism is simpler. The detector 8 rises by winding the pull rope through the winch, and the pull rope is released by rotating the direction. The detector 8 slowly slides down under the action of gravity, and the trajectory of the up and down movement is always limited by the guide rail 95. This driving method is simpler and more stable.

[0055] In this embodiment, see Figure 8 As shown, the deflection mechanism 12 includes a hanging plate 124 which is connected to rotate along the X-axis and is used to install the X-ray machine 7. A driven gear 123 is fixedly installed on the hinge shaft of the hanging plate 124. The driven gear 123 is meshed with a driving gear 122. The driving gear 122 is fixedly set on the output shaft of the motor 121, and the motor 121 is fixedly installed on the frame 1.

[0056] In this embodiment, a first camera 3 is installed on the frame 1 in the direction of the X-axis, and the first camera 3 is electrically connected to the central processing unit 4. A second camera 11 for capturing the position of the detector 8 is installed on the frame 1 or the X-ray machine 7 along the Y-axis direction, and the second camera 11 is electrically connected to the central processing unit 4, as well as an infrared head 10 for emitting visible infrared rays, and the direction of the visible infrared rays emitted by the infrared head 10 is spatially parallel to the central ray direction of the X-ray machine 7 and is located on the plane where the X-axis is located. The frame 1 is also provided with a plurality of rollers 2 for sliding contact with the transmission line, and hanging rings 5 ​​respectively provided on the frame 1 for hanging the detection device.

[0057] The actual test operation can be performed according to the following steps:

[0058] The detection device is tested by using a lifting rope to tie the lifting ring 5 set on the frame 1 or on the frame 1 to the drone, and the drone is controlled to perform a test lift to check the posture of the detection device and whether the video signal sent back to the control terminal by the first camera 3 and the second camera 11 is clear; if the detection standard is not met, it needs to be re-debugged, if the detection standard is met; the control terminal is a handheld terminal that establishes a communication connection with the central processing unit and is used to issue control instructions. The communication method between the control terminal and the central processing unit can be wired or wireless. Generally speaking, wireless methods are used, and existing wireless control terminal equipment can be used.

[0059] The detection device is hoisted by visually manipulating the drone to hoist the detection device above the four-split conductor that needs to be detected, and then the detection device is aligned with the four-split conductor through the real-time image sent back by the first camera 3 on the control terminal, and the detection device is placed on the four-split conductor;

[0060] The detection device is in place, and the detection device is slid along the wire to the detection area by translating the drone, and the locking mechanism 6 is locked to fix the detection position;

[0061] Center ray alignment, adjust the pitch angle of the X-ray machine 7 until the infrared spot of the upper / lower wire on the side close to the detector 8 can be seen at the center of the wire in the picture sent back by the second camera 11;

[0062] Align the detectors and adjust the position of the detector 8 until the detector 8 completely covers the wire where the infrared light spot is located and the closest distance between the edge of the detector 8 and the edge of the wire is not less than 10 cm;

[0063] X-ray detection: turn on the X-ray machine 7 and the detector 8 and take pictures according to the preset X-ray intensity; repeat the above steps to take pictures of another wire on the same side to obtain a detection picture;

[0064] For the reversing test, the locking mechanism 6 is released, the test device is lifted again by the drone and rotated 180° along the Z axis, and the test device is placed again on the four-split conductor, and the above steps are repeated until the test is completed.

[0065] The detection method provided in this embodiment adopts single-sided transmission line fitting detection, which avoids the problem of overlapping fitting imaging in the existing technology of suspended detection from the perspective of spatial layout, thereby reducing the proportion of invalid images and eliminating the detection blind spot problem caused by overlapping imaging. Furthermore, through the structural design of the adjustable detector and the pitch X-ray machine 7, the up and down movement of the detector 8 and the pitch adjustment of the X-ray machine 7 can realize the detection of two transmission line fittings at a single position, which is more efficient than the existing single-wire detection.

[0066] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
