[0042] See also Figure 1-6 The utility model provides a technical solution: a cable microwave radiation cross-linking protection device, comprising a housing 1 and a microwave radiation unit arranged in a straight line and horizontally inside the housing 1, the microwave radiation unit comprising: a cable guide 9, which is provided with a through hole extending in a straight line and horizontally for the cable to enter and exit; a microwave magnetron 10, which is arranged at intervals on the outer surface of the cable guide 9 extending along the axis direction thereof; specifically, the cable microwave radiation cross-linking protection device also includes side panels 2, which are installed on both sides of the housing 1, and the cable guide 9 passes through the through holes opened on the surface of the side panels 2 201; a pipe fitting 4, which is arranged on the side of the side plate 2; a clamping structure, which is arranged in the pipe fitting 4 and is used to position and support the cable guide 9; wherein the clamping structure includes at least two clamping parts, and the clamping part includes an electric telescopic rod 5, the bottom of which is arranged on the inner wall of the pipe fitting 4; an arc plate 6, one side of which is provided with an arc groove that fits the cable guide 9, and the other side of the arc plate 6 is connected to the output end of the electric telescopic rod 5; the cable microwave radiation cross-linking protection device also includes a screw 3, which is arranged in a screw hole opened in the side plate 2, and one end of the screw 3 is screwed into the side of the casing 1;

[0043] The above technical solution can be used to clamp and fix the cable guide 9. When in use, the cable guide 9 is first passed through the through slot 8 of the cover 7 on the left side of the casing 1, so that the cable guide 9 enters the through hole 201 of the pipe 4, until the cable guide 9 is passed out from the other end of the through slot 8 of the cover 7 on the right side of the casing 1. The electric telescopic rod 5 is started to drive the arc plate 6 to move, and the arc plate 6 clamps and fixes the cable guide 9, thereby completing the fixation of the cable guide 9.

[0044] A protective structure is provided in the housing 1, and the protective structure includes at least two protective units, and the protective unit includes: a protective cover 11; a lead plate sleeve 13, which is embedded in a groove opened inside the protective cover 11, and both sides of the protective cover 11 and the lead plate sleeve 13 are provided with slots for the cable guide 9 to pass through, and the slots are respectively first slots 12 opened on both sides of the protective cover 11, and second slots 14 opened on both sides of the lead plate sleeve 13;

[0045] By adopting the above technical solution, the microwave magnetron 10 on the outer surface of the cable guide 9 can be completely covered by the lead plate sleeve 13, and the microwave radiation generated by the microwave magnetron 10 when working can be reflected inside the lead plate sleeve 13, thereby avoiding the disadvantage that a large amount of microwave radiation generated by the microwave magnetron 10 when in use affects human health, protecting the health of the staff, eliminating the need for the staff to wear protective clothing, and increasing convenience.

[0046] The cable microwave radiation cross-linking protection device also includes a driving structure, which is used to drive the two protective covers 11 to close or separate from each other, thereby synchronously driving the lead plate sleeve 13 to cover or expose the microwave irradiation unit; specifically, the driving structure includes: a fixed block 20, which is arranged on the surface of the protective cover 11; a motor 21, which is installed outside the casing 1; a screw rod 22, which is a bidirectional screw rod, and is connected to the output shaft of the motor 21, and the screw rod 22 is matched with a screw rod groove 23 provided in the fixed block 20; a guide structure, which is used to guide the fixed block 20 to move along the screw rod 22, wherein the guide structure includes a guide rod 24, one end of which is fixed inside the casing 1, and the other end of the guide rod 24 is slidably matched with a guide groove 25 provided in the fixed block 20;

The screw rod 22 drives the fixed block 20 to slide straight along the guide rod 24, thereby driving the protective cover 11 to close together. The protective cover 11 drives the lead plate sleeve 13 to move synchronously. The lead plate sleeve 13 covers all the microwave magnetron 10 on the outer surface of the cable guide 9 until the lead plate sleeve 13 is closed together seamlessly and the protection function can be started.

[0048] Further, such as Figure 4 As shown, the pipe 4 is threadedly connected to the cover 7, and the cable guide 9 passes through the through groove 8 provided on the surface of the cover 7;

[0049] The adoption of the above technical solution can further improve the sealing and isolation effect, and prevent foreign matter from entering the housing 1 through the gap between the pipe 4 and the cable guide 9 .

[0050] Further, such as Figure 6 As shown, the cable microwave radiation cross-linking protection device also includes a mounting structure, which is used to remove or install the lead plate sleeve 13 from the protective cover 11. Specifically, the mounting structure includes at least one mounting portion, and the mounting portion includes a bolt 19, which is threadedly connected to a bolt hole 17 opened on the side of the protective cover 11, and the end of the bolt 19 is connected to a limiting hole 18 opened on the side of the lead plate sleeve 13;

[0053] The microwave magnetron 10 can be connected to a power source by adopting the above technical solution. As a possible situation, in order to avoid interference between the wire and the lead plate sleeve 13, a power source can be set inside the lead plate sleeve 13, and the power source and the microwave magnetron 10 are connected to the power source.

[0054] Working principle: When in use, first pass the cable guide 9 through the through slot 8 of the cover 7 on the left side of the casing 1, so that the cable guide 9 enters the through hole 201 of the pipe 4, until the cable guide 9 passes through the other end of the through slot 8 of the cover 7 on the right side of the casing 1, start the electric telescopic rod 5 to drive the arc plate 6 to move, the arc plate 6 clamps and fixes the cable guide 9, and then start the motor 21 to drive the screw rod 22 to rotate, the screw rod 22 drives the fixing block 20 to slide straight along the guide rod 24, thereby driving the protective cover 11 to close together, the protective cover 11 drives the lead plate sleeve 13 to move synchronously, and the lead plate sleeve 13 covers all the microwave magnetrons 10 on the outer surface of the cable guide 9, until the lead plate sleeve 13 closes together seamlessly, then the protection function can be started;

[0055] When the cable enters through the opening of the cable guide 9, after the cable passes through the cable guide 9, the microwave magnetron 10 irradiates the cable surface coating material with microwaves, thereby inducing the initiator therein to produce free radicals, resulting in a cross-linking reaction, thereby improving the production quality of the cable. Since the lead plate sleeve 13 is provided, the microwave magnetron 10 can be completely covered by the lead plate sleeve 13, so that the microwave radiation generated by the microwave magnetron 10 when working can be reflected inside the lead plate sleeve 13, avoiding the disadvantage of a large amount of microwave radiation generated by the microwave magnetron 10 when in use, which affects human health, and eliminating the operation of the staff wearing protective clothing, thereby increasing convenience.
