Description

Technical Field

[0001] The utility model relates to the technical field of radiation accelerator cross-linking cables, in particular to a radiation accelerator cross-linking cable device. Background Art

[0002] Irradiation cross-linked cable uses a high-energy electron beam generated by an electron accelerator to irradiate the insulation layer of the cable, which changes the linear molecular structure of the cable's insulation layer into a three-dimensional network structure, forming a three-dimensional lattice smaller than a water molecule, and forming a dense layer on the surface and inside of the polyethylene, thereby effectively preventing the combination of hydroxide and water molecules. This cross-linking method not only improves the temperature resistance, wear resistance and flame retardancy of wires and cables, but more importantly, it plays a water-blocking role.

[0003] When irradiating cables, due to the large diameter of some cables, the electron accelerator cannot irradiate all positions on the outer surface of the cables, resulting in poor cable irradiation effect. Secondly, during the irradiation process, the cables need to be moved continuously. The existing conveyor belts cannot move the cables at a uniform speed when transporting the cables, resulting in unsatisfactory irradiation effect. Finally, only a part of the radiation dose absorbed by the irradiation cross-linking of the cable insulation and sheath materials is used for chemical and molecular structure transformation, while most of the radiation energy is converted into molecular excitation and heat, which will cause the temperature of the cable surface to rise sharply and damage the insulation layer of the cable. Therefore, a irradiation accelerator cross-linking cable device is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a radiation accelerator cross-linking cable device to solve the problems raised in the above background technology.

[0025] There are four electron accelerators 4, three of which are fixed inside the protective cover 2, and one electron accelerator 4 is fixed at the bottom end of the groove 5; there are two groups of brackets 6, and the other group of brackets 6 is fixed between the motor 12 and the workbench 1; there are five air outlet pipes 11, which are fixed at equal intervals on the top of the connecting pipe 10, and one end of the air outlet pipe 11 away from the connecting pipe 10 is fixedly connected to the workbench 1; there are several bumps 16, which are arranged in a matrix at the top of the workbench 1.

[0026] Working process: When the device is used, it is installed in a suitable position, and the external power supply provides power to the electrical equipment of the device. There is a protective cover 2 on the top of the workbench 1, and material ports 3 are provided at both ends of the protective cover 2, so that the cable 17 can enter the irradiation area from the material port 3 on one side, and then leave the protective cover 2 through the material port 3 on the other side. Three electron accelerators 4 are fixed on the inner side wall of the protective cover 2. A groove 5 is provided on the upper surface of the workbench 1, and an electron accelerator 4 is also installed inside the groove 5. Through the irradiation of multiple electron accelerators 4 in different directions, the cable 17 to be processed can be irradiated in all directions. There is a device on the outside of the protective cover 2 to provide assistance for the movement of the cable 17. There is a motor 12 under the workbench 1, and the power output shaft of the motor 12 is connected to the rotating shaft 13. The silicone wheel 14 is fixed on the outside of the rotating shaft 13. A gear 15 is fixed on the top of the rotating shaft 13.

Since the top of the outlet pipe 11 is connected to the air vent reserved by the workbench 1, the low-temperature air will enter the protective cover 2 from the air vent to cool the environment inside the protective cover 2. Excessive heat will be carried out of the protective cover 2 by the flowing air, which can cool the cable 17 and prevent the surface temperature of the cable 17 from being too high, causing changes in the chemical properties of the insulation layer and the like, thereby affecting its working effect.
