Embodiment 1

[0037] Attached to the manual Figure 1-Figure 5 The shown X-ray detection device for overhead line fittings includes an X-ray detection device 3 suspended on the line fitting 4, and a control receiving terminal that is communicatively connected to the X-ray detection device 3, and also includes an X-ray detection device for passing through a hanging rope. 2. The X-ray detection device 3 is suspended from the remote control drone 1 on the line fitting 4, and the X-ray detection device 3 includes a transmitter 33 and a detection device for receiving X-rays sent by the transmitter 33 The transmitter 31, and the pylon 32 that is fixedly connected and keeps the transmitter 33 and the detector 31 aligned with each other; the use of the existing high-power remote control drone 1 can satisfy the portable X-ray detection device 3 hoisting and hanging To the designated line fittings 4, it completely replaces the manual tower climbing operation, and solves the problem of X-ray radiation...

Embodiment 2

[0039] This embodiment is further improved on the basis of Embodiment 1. In order to facilitate the recovery of the remote control drone 1 during long-term detection operations, the bottom of the remote control drone 1 is provided with a sling hook 7. For details, see details Image 6 and Figure 7 In the structure shown in the figure, the hanging rope hook 7 includes a mounting base 6 connected to the remote control drone 1 through a fastener 5. The mounting base 6 is rotatably connected with a hook body, and the hook body includes a The hook portion 72 on which the rope 2 is sheathed is provided with a bending portion 71 between the hook portion 72 and the root of the hook body, which enables the hook portion 72 to rotate freely eccentrically relative to the mounting seat 6 . The hanging rope hook 7 of the present invention is provided separately, and is specially designed to be separated from the hanging rope 2 when the remote control drone 1 is recovered. Because the slin...

Embodiment 3

[0043] In order to better play the role of the above-mentioned X-ray detection device, the present application also provides a method for X-ray detection of overhead line fittings, the operation of the method is realized based on the above-mentioned overhead line fittings X-ray detection device, and specifically includes the following steps:

[0044] Step ST100, the detection device is ready: one end of the suspending rope 2 is bound in an O shape, the other end is bound in a Y shape, and one end of the O-shaped binding is sleeved on the hook portion 72 and the tripping portion 73 is connected to the electromagnet unit 8. Pull in, and fasten the two free ends of the Y-shaped binding to the two upper ends of the hanger 32 respectively;

[0045] Step ST200, the detection device is in place: operate the remote control terminal to control the remote control drone 1 to hoist the X-ray detection device 3, until the X-ray detection device 3 is hoisted through the hanger 32 and hangs o...

Abstract

The invention discloses an X-ray detection device for overhead line hardware. The devicecomprises an X-ray detection device suspended on a line fitting, a control receiving terminal in communication connection with the X-ray detection device, and a remote control unmanned aerial vehicle used for lifting the X-ray detection device through a lifting rope and suspending the X-ray detection device on the line fitting, and the X-ray detection device comprises a transmitter, a detector used for receiving X-rays transmitted by the transmitter, and a hanger which is fixedly connected with the transmitter and the detector and keeps the transmitter and the detector aligned with each other. The invention further provides a detection method, the remote control unmanned aerial vehicle is adopted for hoisting the detection device, and the problems of ray radiation injury and high-altitude falling risk existing when people climb the tower and operate on the tower at present are solved; and lifting of the unmanned aerial vehicle can completely replace manual work, and all possible injuries to the human body and existing potential safety hazards in the detection process are eliminated.

Description

technical field [0001] The invention relates to the technical field of X-ray detection, in particular to the technical field of charged high-altitude defect detection for overhead high-voltage transmission lines, line fittings, etc. based on X-rays, and in particular to an X-ray detection device and method for overhead line fittings. Background technique [0002] The defect detection of high-altitude transmission lines is to find defective fittings in time to avoid major losses caused by power outages caused by line failures. The defects of high-voltage transmission lines are mainly divided into two types, one is the line failure caused by the internal defects of the line fittings, such as internal cracks caused by metal fatigue; the other is the local stress, virtual position or other caused by the crimping of the fittings. Crimping defect. Due to the large internal stress of transmission lines for a long time, metal fatigue is prone to occur, and the importance of high-vo...
