[0030] like Figures 1 to 4 As shown, an X-ray device for inspecting submarine cables includes a cable support device 100, a rotating support part 200, an X-ray machine inspection part 300, a flat plate inspection part 400, a translation device 500, and a hydraulic lifting transfer vehicle 600. The cable support device 100 supports a horizontally positioned cable 1 to be inspected. The lower end of the rotating support part 200 is sequentially connected to the translation device 500 and the hydraulic lifting transfer vehicle 600. An opening is provided at the same position on both the rotating and non-rotating parts of the rotating support part 200, with the opening height matching the height of the cable 1 to be inspected. The X-ray machine inspection part 300 and the flat plate inspection part 400 are symmetrically arranged on the rotating part of the rotating support part 200, and the X-ray machine... The central axis of the X-ray emitted by the detection unit 300 and the central axis of the flat plate of the flat plate detection unit 400 both pass through the rotation axis of the rotating support unit 200. Without damaging the cable 1 being tested, the translation device 500 drives the rotating support unit 200 to move along the axial direction of the cable 1 being tested. The hydraulic lifting transfer vehicle 600 drives the rotating support unit 200 to move and make the cable 1 being tested pass through the opening of the rotating support unit 200 and reach the rotation axis of the rotating support unit 200. The X-ray machine in the X-ray machine detection unit 300 is turned on, and projection detection can be performed in the flat plate detection unit 400. The cable 1 being tested is not cut. By continuously changing the detection position, continuous detection can be achieved.

[0031] like Figures 3 to 5 As shown, the rotating support 200 includes a C-gear 14, a vertical plate 24, a roller seat 26, guide wheels 25, and a power unit. The vertical plate 24 is the main support structure, connected to the translation device 500 at its bottom, and has an opening on its upper side face. The roller seat 26 is coaxially engaged with the C-gear 14. The roller seat 26 is an annular structure with an opening, the opening position of which is consistent with that of the C-gear 14. Several guide wheels 25 are respectively provided on the inner and outer circumferences of the roller seat 26, and the axis of the guide wheels 25 is positioned and connected to the vertical plate 24. The output shaft of the power unit is connected to the main drive gear 17, the axis of the main drive gear 17 is positioned and connected to the vertical plate 24, and the circumferential teeth of the main drive gear 17 mesh with the C-gear 14 for transmission. Under the clamping of the guide wheels 25 on the inner and outer circumferences, the roller seat 26 ensures both the circumferential movement of the C-gear 14 and the connection with the vertical plate 24.

[0032] The power unit includes a main drive gear 17, a secondary drive gear 20, pulleys, a synchronous belt I19, and a servo motor 23. The main drive gear 17 and the secondary drive gear 20 are each coaxially equipped with pulleys, which together engage with the synchronous belt I19 for transmission. Both the main drive gear 17 and the secondary drive gear 20 simultaneously mesh with a C-type gear 14 for transmission. The servo motor 23 is positioned on the vertical plate 24, and its output shaft is connected to the main drive gear 17 for transmission. The symmetrical meshing of the main drive gear 17 and the secondary drive gear 20 with the C-type gear 14 overcomes the problem of discontinuous transmission caused by the open portion of the C-type gear 14. When the open portion reaches the position of either the main drive gear 17 or the secondary drive gear 20, the other gear acts as the transmission element, ensuring the continuity of the 360° rotation detection.

[0033] like Figure 4 As shown, the back of the upright plate 24 is provided with a fixed cable chain groove 28 and a rotating cable chain groove 29. The rotating cable chain groove 29 is concentrically arranged within the fixed cable chain groove 28, which is positioned on the back of the upright plate 24. The rotating cable chain groove 29 is provided with a connecting plate 16 bent towards the front surface of the upright plate 24. The connecting plate 16 is connected and positioned to the front surface of the C-shaped gear 14. The rotating cable chain groove 29 is located on the back and is used to insert cable chains and wires / cables.

[0034] like Figure 2 As shown, the front surface of the C-type gear 14 is symmetrically provided with fixing plates 15 on the upper and lower sides. The upper fixing plate 15 is connected to the X-ray machine detection unit 300, and the lower fixing plate 15 is connected to the flat plate detection unit 400. This ensures that the X-ray machine detection unit 300 and the flat plate detection unit 400 are located on the same vertical axis.

[0035] like Figure 6 and Figure 7 As shown, the X-ray machine detection unit 300 includes an integrated X-ray machine 4, a controller 9, an X-ray machine support 13, and a vertical transmission mechanism. The integrated X-ray machine 4 and the controller 9 are respectively connected to the X-ray machine support 13, and the X-ray machine support 13 is connected to the movable part of the vertical transmission mechanism. The integrated X-ray machine 4 is vertically adjusted to maintain its distance from the cable 1 being inspected via the controller 9 on the vertical transmission mechanism. Simultaneously, the controller 9 can receive wireless signals to remotely control the opening and closing of the integrated X-ray machine 4.

[0036] like Figure 8 and Figure 9As shown, the flat panel detection unit 400 includes a flat panel box assembly 32, a manual grating assembly 31, a wireless receiver 33, a limiting plate 35, a flat panel support 34, and a vertical transmission mechanism. The limiting plate 35 is connected to the front and rear sides of the flat panel box assembly 32, and the manual grating assembly 31 is connected to the limiting plate 35. The wireless receiver 33 is connected to the front end of the bottom of the flat panel box assembly 32, and the rear end is connected to the flat panel support 34. The flat panel support 34 is connected to the movable part of the vertical transmission mechanism. The flat panel box assembly 32 can move up and down via the vertical transmission mechanism to adjust the projection distance of the X-ray from the integrated X-ray machine 4 onto the flat panel box assembly 32 after passing through the tested cable 1. The manual grating assembly 31 is used to adjust the clarity of the flat panel image, and the wireless receiver 33 is used to receive and wirelessly transmit the data from the image of the flat panel box assembly 32.

[0037] The vertical transmission mechanism includes a handwheel 11, a longitudinal lead screw 5, a bearing seat 7, and longitudinal guide rails 8. Two parallel longitudinal guide rails 8 are positioned on a fixed plate 15. The longitudinal lead screw 5 is located between the two guide rails 8, and both ends of the longitudinal lead screw 5 are supported by the bearing seat 7. One end of the longitudinal lead screw 5 extends out of the bearing seat 7 and is connected to the handwheel 11. A threaded nut is connected to the longitudinal lead screw 5, which serves as a moving part of the vertical transmission mechanism. By rotating the handwheel 11, the longitudinal lead screw 5 can be rotated, and the nut on the longitudinal lead screw 5 moves up and down, thereby adjusting the vertical movement of the X-ray machine inspection section 300 or the flat plate inspection section 400. For those skilled in the art, other transmission structures can also be used to adjust the vertical position of the X-ray machine inspection section 300 or the flat plate inspection section 400.

[0038] like Figure 10 As shown, the translation device 500 includes a positioning base 51, transverse guide rails 50, a transverse lead screw 47, and a reduction motor 44. Two transverse guide rails 50 are mounted on the horizontal positioning base 51, and the transverse lead screw 47 is supported by a bearing seat between the two transverse guide rails 50. The lead screw nut 48 on the transverse lead screw 47 is connected to the rotating support part 200. A reduction motor 44 is located at one end of the positioning base 51, and the output shaft of the reduction motor 44 is connected to a pulley. One end of the transverse lead screw 47 is also connected to a pulley, and both pulleys are connected to a synchronous belt II 43. The translation device 500 also adopts the principle of lead screw transmission, using the reduction motor 44 to drive the rotating support part 200 to move longitudinally, causing the X-ray machine detection part 300 to move along the axis of the cable, thereby increasing the detection length of the cable.

[0039] like Figure 11 As shown, the hydraulic lifting transfer vehicle 600 has a rolling bearing 55 on its bearing plate 54. The rolling bearing 55 supports the positioning seat 51 of the translation device 500, which not only facilitates the entry of cables into the X-ray machine inspection section 300 for inspection, but also facilitates indoor and outdoor transfer.
