[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Depend on Figures 1 to 5 The invention provides a method of detecting a line by emitting X-rays, wherein the method comprises: providing a drone 1 and a detection frame 2 placed under the drone 1, wherein the detection frame 2 comprises a horizontal receiving platform 3, wherein a vertical bracket 4 is fixed to one side of the bottom of the receiving platform 3, wherein a transmitter 5 is fixed to the bracket 4, wherein the transmitter 5 detects the line by emitting X-rays, wherein four corners of the top of the receiving platform 3 are fixed with hanging rings 6, wherein the hanging rings 6 are provided with connecting ropes 7, wherein one end of the four connecting ropes 7 is fixed with the same connecting block 8, wherein a limiting column 9 is fixed to the top of the receiving platform 3, wherein the limiting column 9 is located at the intersection of the diagonals of the four hanging rings 6, and wherein the connecting block 8 slides on the limiting column 9, wherein the connecting rope 7 is provided with a connecting rope 7, wherein the connecting rope 7 is provided with a connecting rope 8 ... A plurality of equally spaced placement slots 10 are provided at the bottom of the receiving station 3. The drone 1 carries a wireless transmission terminal. The user carries a ground remote controller in his hand and receives detection information through the ground remote controller and the wireless transmission terminal. A ground workstation can also be set up and used as a control center to control various components on the detection tooling. The drone 1, the detection frame 2, and the transmitter 5 are set up. In daily use, the drone 1 is controlled by the ground remote controller to lift the detection frame 2 and other equipment onto the detection line. When the receiving station 3 is placed on the line to be detected, the line can be placed inside the placement slot 10 for easy fixation.

[0028] In order to facilitate the separation of the drone 1 and the detection frame 2, four symmetrically distributed ropes 11 are fixed at the bottom of the drone 1, and the same connecting tube 12 is fixed at one end of the four ropes 11 away from the drone 1. A through hole is opened inside the connecting tube 12, and the diameter of the through hole is larger than the diameter of the limiting column 9, so that the connecting tube 12 can be sleeved on the limiting column 9. A power supply 13 is fixed on the top of the connecting tube 12, and the power supply 13 is electrically connected to the wireless transmission terminal. A strong electromagnet 14 located below the power supply 13 is fixed on the connecting tube 12, and a sliding plate 15 that slides up and down is arranged below the strong electromagnet 14. The magnetic force of the strong electromagnet 14 is very strong and can strongly attract the sliding plate 15 to move upward. The sliding plate 15 is coaxially arranged with the connecting tube 12, and the connecting tube 12 rotates on the connecting tube 12. The dynamic connection is provided with a plurality of connecting arms 16 evenly distributed around the circumference. In the present embodiment, the number of the connecting arms 16 is four. A conical block 17 is fixed at the bottom of the connecting arm 16. An annular groove 18 is provided on the connecting block 8. The conical block 17 engages with the annular groove 18. Through the connection tube 12, the slide 15 and the strong electromagnet 14, when the UAV 1 needs to be separated from the detection tooling, the user transmits a separation signal to the wireless transmission terminal through the ground remote control device, the wireless transmission terminal controls the strong electromagnet 14 to be closed, and the slide 15 slides downward under the action of gravity. At this time, the upper half of the connecting arm 16 is buckled into the inside of the connecting tube 12, and finally the connecting arm 16 is disengaged from the annular groove 18, so that the UAV 1 can be quickly separated from the detection tooling, and the detection tooling can still perform fault detection on the power transmission line;

[0029] A feedback device is provided at the bottom of the connecting tube 12. The feedback device may be an infrared distance detection device or a miniature camera. In the present embodiment, a miniature camera is preferably used. The miniature camera is electrically connected to a ground remote control device.

[0030] In order to facilitate the disengagement of the connecting arm 16 from the annular groove 18 , the center of gravity of the connecting arm 16 is located at the upper half of the connecting arm 16 .

[0031] refer to Figure 1 As shown, in order to facilitate the connection of the detection tooling on the transmission line, two symmetrically distributed guide plates 19 are fixed on one side of the receiving station 3. The guide plates 19 can play a certain guiding role. During use, it is only necessary to control the drone 1 to hang the detection tooling close to the transmission line. The guide plates 19 can be used as a reference. The transmission line only needs to contact the lower side of the guide plates 19. Under the guidance of the guide plates 19, the installation of the detection tooling and the transmission line can be completed.

[0032] In order to facilitate the sleeve of the connecting tube 12 on the limiting column 9, the bottom of the through hole is provided with an arc angle.

[0033] refer to Figure 1As shown, in order to facilitate the reconnection of the drone 1 and the detection tooling, at least one arc-shaped plate 20 is fixed on the top of the receiving platform 3. In this embodiment, the number of the arc-shaped plates 20 is four, and the four arc-shaped plates 20 are evenly distributed around the circumference to form a ring. There are gaps between the four arc-shaped plates 20, and the four connecting ropes 7 are respectively located in the corresponding gaps;

[0034] When the drone 1 is charged and then connected to the detection tooling again, it is necessary to control the connecting tube 12 to be sleeved on the limit column 9. At this time, the user uses the arc plate 20 as a reference, controls the connecting tube 12 to slowly approach and be coaxial with the four arc plates 20, and then sleeves it downward on the limit column 9. The position information can be fed back in real time through the micro camera. When the image of the micro camera becomes completely black, it means that the connecting tube 12 is in contact with the connecting block 8. Then the user transmits a connection signal to the wireless transmission terminal through the ground remote control device. The wireless transmission terminal controls the strong electromagnet 14 to turn on and move upward under the attraction of the strong electromagnet 14. When the slide 15 moves upward, its edge contacts the connecting arm 16. As the slide 15 continues to move, the conical block 17 of the connecting arm 16 buckles inward and engages with the annular groove 18. At this time, the drone 1 can be controlled to drive the detection tooling to separate from the power transmission line.

[0035] In order to prevent the connection block 8 and other components from being conductive under the action of a strong electromagnetic field, the connection block 8, the connection arm 16, the connection tube 12 and the slide 15 are all made of hard insulating materials.

[0036] In order to facilitate the transportation of the detection tooling, the bracket 4 is divided into an upper and lower part. The transmitter 5 is located in the lower part of the bracket 4. A rotation locking device is provided between the upper and lower parts of the bracket 4. A rotation locking device is also provided between the upper part of the bracket 4 and the receiving platform 3. The rotation locking device can be a buckle. The upper and lower parts of the bracket 4 are rotatably connected. When in use, the buckle fixes the two parts. The buckle is released during transportation. Similarly, the receiving platform 3 and the detection frame 2 are also fixed by the buckle.

[0037] In order to reduce the weight of the detection tooling and facilitate hoisting and detection, the receiving platform 3 and the detection frame 2 are made of carbon fiber.

[0038] When the utility model is used:

[0039] First, the user controls the drone 1 through the ground remote control to drive the detection tooling to fly. When testing the power transmission line, the guide plate 19 is used to assist the installation of the detection tooling and the power transmission line, and the line is placed inside the opening placement slot 10;

[0040] Then, when the UAV 1 needs to be separated from the inspection tooling, the user transmits a separation signal to the wireless transmission terminal through the ground remote control device, and the wireless transmission terminal controls the strong electromagnet 14 to be turned off, and the slide 15 slides downward under the action of gravity. At this time, the upper part of the connecting arm 16 is buckled into the inside of the connecting tube 12, and finally the connecting arm 16 is disengaged from the annular groove 18;

[0041] Secondly, when the drone 1 is charged and then connected to the detection tooling again, it is necessary to control the connecting tube 12 to be sleeved on the limit column 9. At this time, the user uses the arc plate 20 as a reference, controls the connecting tube 12 to slowly approach and be coaxial with the four arc plates 20, and then sleeves it downward on the limit column 9. The position information can be fed back in real time through the micro camera. When the image of the micro camera becomes completely black, it means that the connecting tube 12 is in contact with the connecting block 8. Then the user transmits a connection signal to the wireless transmission terminal through the ground remote control device. The wireless transmission terminal controls the strong electromagnet 14 to turn on and move upward under the attraction of the strong electromagnet 14. When the slide 15 moves upward, its edge contacts the connecting arm 16. As the slide 15 continues to move, the conical block 17 of the connecting arm 16 buckles inward and engages with the annular groove 18. At this time, the drone 1 can be controlled to drive the detection tooling to separate from the power transmission line.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
