When the X-ray tube emits X-rays, the rotor can drive the anode to rotate and drive the wavy target panel to rotate, so that the reflection area of ​​the wavy target panel is constantly changing. To dissipate heat and avoid overheating, at the same time, the contact surface between the wavy target panel and the X-rays keeps changing. Since the wavy target panel is constantly rotating while reflecting the X-rays, the incident angle of the X-rays is also constantly changing, which causes the X-rays reflected by the wavy target panel to also have angle changes. The continuous changes of the waves on the surface of the wavy target panel are utilized to achieve the change in the angle of the refracted X-rays to produce a scanning effect, thereby realizing a large-scale scanning of the tension clamp without increasing the power of the X-ray refraction equipment or changing the position of the tension clamp, thereby expanding the X-ray detection range.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Please refer to Figure 1 , 2 3. An embodiment of the present invention provides a variable-angle X-ray detection device for a transmission line tension clamp, comprising an X-ray tube 1, a clamping mechanism 2 and an X-ray receiving panel 3.

[0043] Combination Figure 4 , 5 As shown in Figures 6 and 7, the X-ray tube 1 includes a housing 101, and a stator 102, a rotor 103, an anode 104, a wave-shaped target panel 105, a collecting end 106 and a cathode 107 arranged in the housing 101. The housing 101 is cylindrical, and the stator 102, the rotor 103, the anode 104, the wave-shaped target panel 105, the collecting end 106 and the cathode 107 are arranged in sequence along the axial direction of the housing 101. One end of the rotor 103 is connected to the stator 102 and the other end is connected to the anode 104, and the wave-shaped target panel 105 is installed on the surface of the anode 104. Here, the stator 102 is fixed in the housing 101 through a mounting shaft 108, and the mounting shaft 108 is connected to the stator 102, and the rotor 103 is installed in the stator 102 and connected to the anode 104. The rotation of the rotor 103 can drive the anode 104 to rotate, and further drive the wave-shaped target panel 105 to rotate.

[0044] The collecting end 106 is arranged opposite to the wavy target panel 105, and the cathode 107 is connected to the collecting end 106. Here, the anode 104 is in the shape of a disk 505, and the wavy target panel 105 is a disk 505 with a wavy surface. The collecting end 106 is eccentrically arranged relative to the wavy target panel 105, and an emission window 110 is provided on the surface of the housing 101 between the wavy target panel 105 and the collecting end 106.

[0045] Since the surface of the wavy target panel 105 is wavy, the X-rays are reflected on the surface of the wavy target panel 105 and then emitted from the emission window 110. The wavy shape of the surface of the wavy target panel 105 can be flexibly set. For example, in this embodiment, the parameter equation of the surface of the wavy target panel 105 is:

[0046]

[0047] Where A is the amplitude, which determines the maximum height of the surface of the wavy target panel 105;

[0048] ω is the angular frequency, which determines the wavelength of the surface of the wavy target panel 105;

[0049] is the phase, which determines the translation of the surface of the wavy target panel 105;

[0050] k is a longitudinal offset, which determines the reference height of the surface of the corrugated target panel 105 .

[0051] refer to Figure 7 As shown in the schematic diagram of the change in the reflection range of X-rays on the surface of the middle wavy target panel 105, the X-rays emitted by the cathode 107 of the X-ray tube 1 are emitted through the collecting end 106, and the X-rays are reflected on the surface of the wavy target panel 105 and emitted through the emission window 110. It should be noted that, since the rotor 103 can drive the anode 104 to rotate and drive the wavy target panel 105 to rotate, the reflection area of ​​the wavy target panel 105 is constantly changing, which can dissipate heat and avoid overheating. At the same time, the contact surface between the wavy target panel 105 and the X-rays keeps changing. Since the wavy target panel 105 is constantly rotating while reflecting the X-rays, the incident angle of the X-rays is also constantly changing, which causes the angle of the X-rays reflected by the wavy target panel 105 to change. By utilizing the continuous changes in the waves on the surface of the wavy target panel 105, the angle of the refracted X-rays is changed to produce a scanning effect, thereby realizing a large-scale scanning of the tension clamp without increasing the power of the X-ray refraction equipment or changing the position of the tension clamp, thereby expanding the X-ray detection range.

[0052] like Figure 8As shown, the clamping mechanism 2 is arranged in front of the emission window 110, and is used to clamp the tension clamp to be tested. Specifically, the clamping mechanism 2 includes a base 201, a first motor 202, a rotating seat 203, a second motor 205, a second screw 204 and two clamping blocks 206, the rotating seat 203 is rotatably installed on the upper part of the base 201, the first motor 202 is arranged in the base 201 and connected to the rotating seat 203, the two clamping blocks 206 are arranged oppositely and the bottoms can be slidably connected to the rotating seat 203, the second screw 204 passes through the two clamping blocks 206 and is threadedly connected to the two clamping blocks 206, the thread rotation direction of the part of the second screw 204 threadedly connected to the two clamping blocks 206 is opposite, and the second motor 205 is installed on one side of the rotating seat 203 and connected to the second screw 204.

[0053] The bottom of the two clamping blocks 206 can slide axially along the second screw rod 204. In this embodiment, a second slider 207 is provided at the lower end of each clamping block 206, and a second slide groove 208 is provided at the upper portion of the rotating seat 203. The second slide groove 208 is axially arranged along the second screw rod 204. The lower portions of the two second slide blocks 207 can be slidably embedded in the second slide groove 208. The second screw rod 204 passes through the two second slide blocks 207 and is threadedly connected to the two second slide blocks 207. The second screw rod 204 and the two second slide blocks 207 form a screw mechanism.

[0054] The clamping mechanism 2 is generally fixed to the bottom of the X-ray receiving panel 3 and is located on the side of the X-ray receiving panel 3 close to the X-ray tube 1. The clamping mechanism 2 drives the second lead screw 204 through the second motor 205 to drive the two clamping blocks 206 to approach and clamp the tension clamp to be tested, and can drive the rotating seat 203 to rotate through the first motor 202 to rotate the tension clamp to be tested, thereby adjusting the direction of the tension clamp to achieve detection at different angles.

[0055] The X-ray receiving panel 3 is disposed on the side of the clamping mechanism 2 away from the emission window 110. After the X-rays emitted from the emission window 110 of the X-ray tube 1 irradiate the tension clamp, they are received by the X-ray receiving panel 3 and display the internal condition of the tension clamp.

[0056] like Fig. 9As shown, in some embodiments, a variable angle X-ray detection device for a transmission line tension clamp of the present invention further includes a detection platform 4 and a driving mechanism 5, and the bottom of the X-ray receiving panel 3 is slidably disposed on the detection platform 4. Here, the detection platform 4 is provided with two first slide grooves 401 perpendicular to the X-ray tube 1, and the bottom of the X-ray receiving panel 3 is provided with two first sliders, and the two first sliders are slidably embedded in the two first slide grooves 401 respectively.

[0057] The driving mechanism 5 includes a first screw rod 501, two fixed blocks 502, a transmission block 503 and a driving rod 504. The two fixed blocks 502 are arranged opposite to each other and fixed on the detection platform 4. The transmission block 503 is movably arranged between the two fixed blocks 502. The first screw rod 501 passes through the two fixed blocks 502 and the transmission block 503, and the first screw rod 501 is threadedly connected with the transmission block 503, so that the first screw rod 501 and the transmission block 503 form a screw mechanism. One end of the driving rod 504 is rotatably connected to the transmission block 503, and the other end is rotatably connected to the X-ray receiving panel 3.

[0058] The two ends of the driving rod 504 are respectively connected to the transmission block 503 and the X-ray receiving panel 3 by axial hinge. In this embodiment, both ends of the driving rod 504 are provided with hinge shafts, one of which is rotatably connected to the transmission block 503, and the other is rotatably connected to a fixed plate 507, and the fixed plate 507 is fixed to the back of the X-ray receiving panel 3.

[0059] Rotating the first screw rod 501 can drive the transmission block 503 to move, and the transmission block 503 drives the driving rod 504 to move, so that the driving rod 504 pushes and pulls the X-ray receiving panel 3 to move on the detection platform 4. In this way, the position of the X-ray receiving panel 3 can be adjusted to detect the tension clamp at different positions. In order to facilitate the rotation of the first screw rod 501, a disk 505 and a handle 506 connected to the disk 505 are provided at one end of the first screw rod 501. Turning the handle 506 can easily rotate the first screw rod 501.

[0060] The X-ray tube 1 is generally installed on the detection platform 4. A plurality of support seats 109 are provided at the bottom of the housing 101. The lower ends of the support seats 109 are fixedly installed on the detection platform 4 so that the emission window 110 faces the middle of the X-ray receiving panel 3. In this way, the X-rays emitted by the X-ray tube 1 have a larger irradiation range.

[0061] The embodiment of the present invention provides a variable-angle X-ray detection device for a transmission line tension clamp. The detection process of the tension clamp is as follows:

[0062] First, the tension clamp to be tested is installed on the clamping mechanism 2, the second motor 205 drives the second screw rod 204 to drive the two clamping blocks 206 to clamp the tension clamp, and the first motor 202 drives the rotating seat 203 to rotate, so that the tension clamp is rotated to the required detection angle;

[0063] Then, the first screw rod 501 is rotated to drive the transmission block 503 to move, thereby driving the driving rod 504 to move, thereby pushing the X-ray receiving panel 3 to move on the detection platform 4, and adjusting the X-ray receiving panel 3 to a desired position;

[0064] Finally, the collecting end 106 on the cathode 107 is controlled to emit X-rays. After being reflected on the surface of the wavy target panel 105, the X-rays are emitted from the emission window 110 and irradiated on the tensioning clamp and the X-ray receiving panel 3. The changes of the X-rays after the X-rays pass through the tensioning clamp are utilized so that the X-ray receiving panel 3 receives and displays the internal conditions of the tensioning clamp. The wavy target panel 105 is driven by the rotor 103 to rotate while reflecting the X-rays, resulting in a continuous change in the incident angle of the X-rays, thereby resulting in a change in the angle of the X-rays reflected by the wavy target panel 105. The continuous change of the waves on the surface of the wavy target panel 105 is utilized to achieve the change in the angle of the refracted X-rays, thereby producing a scanning effect, thereby achieving a large-scale scanning of the tension clamp.
