[0001] The utility model relates to the technical field of high-voltage transmission line flaw detection, in particular to an automatic installation and fixing structure of an X-ray flaw detection information collection board for a high-voltage transmission line. Background Art

[0002] High-voltage lines usually refer to power transmission lines that carry voltages above 10kV. High-voltage power transmission is generally carried underground by cables with insulation layers in cities, and is often carried by overhead lines carried by iron towers in the wild. The porcelain bottles (insulating terminals) used at the connection between high-voltage lines and poles and towers are important insulating equipment and require regular inspection and maintenance. In modern industrial production, X-ray detection technology has become an important non-destructive testing technology, widely used in quality inspection, safety inspection, product development and other fields in various industries.

[0003] At present, when using an X-ray flaw detector to detect high-voltage transmission lines, it is usually necessary to install the X-ray flaw detection information acquisition board on a drone, and use the drone to drive it to move for flaw detection. However, during installation, it is usually necessary to use multiple screws to install and fix the X-ray flaw detection information acquisition board. The screwing operation is cumbersome and requires a certain amount of time and human resources. For this reason, we designed an automatic installation and fixing structure for the X-ray flaw detection information acquisition board of high-voltage transmission lines to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and the proposed automatic installation and fixing structure of the high-voltage transmission line X-ray flaw detection information collection plate is simple to operate. The installation plate is placed under the connecting plate and is attached to the bottom of the connecting plate and is located in a plurality of L-shaped fixing plates. The plurality of L-shaped fixing plates can automatically fix the installation plate, and the installation plate and the information collection plate are stably installed on the drone body, which is convenient for flaw detection and information collection of the high-voltage transmission line. After use, the installation plate is easy to remove and is convenient for subsequent fixing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The automatic installation and fixing structure of the X-ray flaw detection information collection board of the high-voltage transmission line includes an unmanned aerial vehicle body, a mounting plate and an information collection board. A connecting plate is installed at the bottom of the unmanned aerial vehicle body, and the mounting plate is placed at the bottom of the connecting plate. The connecting plate is provided with a plurality of fixing components for automatically fixing the mounting plate from all sides of the mounting plate, and a sliding sleeve on the connecting plate is provided with a limiting component that abuts against the side walls of the plurality of fixing components.

[0007] Preferably, the connecting plate is mounted on the bottom of the drone body by a plurality of screws.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The automatic installation and fixing structure of the X-ray flaw detection information collection plate of the high-voltage transmission line places the installation plate under the connecting plate and fits the bottom of the connecting plate and is located in multiple L-shaped fixing plates. When the electromagnet is energized, it can generate an attractive force with the iron block, so that the L-shaped fixing plate slides toward the installation plate to support and fix the installation plate. At this time, under the action of the annular plate's own gravity, the annular plate can descend so that the protrusions are against the side walls of the L-shaped fixing plate, and the L-shaped fixing plate is stably limited and fixed, and the installation plate and the information collection plate are automatically and stably installed on the drone body, which is convenient for flaw detection and information collection of high-voltage transmission lines.

When the flaw detection is completed and the mounting plate needs to be removed, the annular plate is pulled upward to move the protrusion to the top of the L-shaped fixing plate. The electromagnet is powered off, and the spring can pull the L-shaped fixing plate away from the mounting plate, so that the mounting plate falls off the connecting plate. At this time, the L-shaped fixing plate can support the protrusion, which is convenient for fixing the mounting plate again later. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 , the automatic installation and fixing structure of the high-voltage transmission line X-ray flaw detection information collection board includes an unmanned aerial vehicle body 1, a mounting plate 3 and an information collection board 4, a connecting plate 2 is installed at the bottom of the unmanned aerial vehicle body 1, and the connecting plate 2 is installed at the bottom of the unmanned aerial vehicle body 1 by a plurality of screws, so as to facilitate the disassembly and installation of the connecting plate 2, and a battery for powering the unmanned aerial vehicle body 1 and the electromagnet 11 is installed in the connecting plate 2;

[0022] The mounting plate 3 is placed at the bottom of the connecting plate 2, and the information collection plate 4 is installed at the bottom of the mounting plate 3. The information collection plate 4 is installed with components such as an X-ray flaw detector for flaw detection and a camera for image acquisition. The connecting plate 2 is provided with a plurality of fixing components for automatically fixing the mounting plate 3 from all sides of the mounting plate 3. The fixing component includes a fixed slide 6 opened at the bottom of the connecting plate 2, and an L-shaped fixing plate 7 is horizontally slidably connected in the fixed slide 6 and abutted against the bottom of the mounting plate 3. The inner side walls at both ends of the fixed slide 6 are fixedly connected with a limit rod 9. The L-shaped fixing plate 7 is slidably sleeved on the limit rod 9, and the L-shaped fixing plate 7 abuts against the front and rear inner side walls of the fixed slide 6. The limiting rods 9 work together to make the L-shaped fixing plate 7 only move horizontally, and there is a gap between the L-shaped fixing plate 7 and the inner top of the fixing slide 6, the height of the gap is not less than the height of the protrusion 13, and a plurality of springs 8 are connected between the L-shaped fixing plate 7 and the inner side wall of the fixing slide 6. The spring 8 is a tension spring, which can pull the L-shaped fixing plate 7 away from the mounting plate 3 in a natural state. An iron block 10 is embedded in the side wall of one end of the L-shaped fixing plate 7 close to the mounting plate 3, and an electromagnet 11 is embedded in the inner side wall of the fixing slide 6. When the electromagnet 11 is energized, it can generate an attraction force with the iron block 10, so that the L-shaped fixing plate 7 moves toward the mounting plate 3 to fix the mounting plate 3;

[0023] A sliding sleeve on the connecting plate 2 is provided with a limit assembly that abuts against the side walls of multiple fixed assemblies. The limit assembly includes multiple guide slots 12 that penetrate through the side walls of the connecting plate 2. The multiple guide slots 12 are respectively communicated with the multiple fixed slots 6. The side wall of the connecting plate 2 is sleeved with an annular plate 5 that is slidably connected to it. The annular plate 5 abuts against the side walls of the connecting plate 2, so that the annular plate 5 can only slide up and down, and under the action of the annular plate 5's own gravity, the annular plate 5 can move downward. The inner side wall of the annular plate 5 is fixedly connected with multiple protrusions 13. The multiple protrusions 13 pass through the corresponding guide slots 12 and abut against the side walls of multiple L-shaped fixed plates 7. When the protrusions 13 abut against the side walls of the L-shaped fixed plates 7, they can limit the L-shaped fixed plates 7, so that the L-shaped fixed plates 7 can stably fix the mounting plate 3.

[0024] The functional principle of the utility model can be explained through the following operation modes:

[0025] In the utility model, when the automatic installation and fixing structure of the X-ray flaw detection information collection board of the high-voltage transmission line is used, the installation plate 3 is placed under the connecting plate 2 and fits with the bottom of the connecting plate 2, and the electromagnet 11 is powered. The electromagnet 11 can generate an attractive force with the iron block 10, so that the L-shaped fixing plate 7 slides toward the installation plate 3 and abuts against the side wall and bottom of the installation plate 3, and the installation plate 3 is supported and fixed. When the L-shaped fixing plate 7 abuts against the side wall of the installation plate 3, the L-shaped fixing plate 7 no longer supports the protrusion 13, and then under the action of the gravity of the annular plate 5 itself, the annular plate 5 can descend to make the protrusion 13 move down and abut against the side wall of the L-shaped fixing plate 7, and the L-shaped fixing plate 7 is limited and fixed, so that the L-shaped fixing plate 7 cannot move horizontally, and then the installation plate 3 and the information collection board 4 can be automatically and stably installed on the drone body 1, and the high-voltage transmission line is inspected and information is collected through the cooperation of the drone body 1 with the X-ray flaw detector and the camera.

[0026] When the mounting plate 3 needs to be removed, the annular plate 5 is pulled upward to move the protrusion 13 to the top of the L-shaped fixing plate 7, so that the electromagnet 11 is powered off. The spring 8 can pull the L-shaped fixing plate 7 away from the mounting plate 3, thereby allowing the mounting plate 3 to be separated from the connecting plate 2, making it easier to remove the mounting plate 3. At this time, the L-shaped fixing plate 7 slides to the bottom of the protrusion 13, and can support the protrusion 13, making it easier to fix the mounting plate 3 again later.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
