Description

Electron accelerator system Technical Field

[0001] This invention relates to an electron accelerator system. Background Technology

[0002] Cable irradiation refers to the process of subjecting cables to radiation treatment, typically through radiation crosslinking technology to enhance cable performance. This process primarily serves the following purposes:

[0003] Enhance the physical properties of cables: Radiation cross-linking can improve the heat resistance, abrasion resistance and mechanical strength of cables, making them perform better in harsh environments.

[0004] Improving the electrical performance of cables: Irradiation treatment can make the insulation material of cables more stable, thereby improving the insulation performance and voltage withstand capability of cables.

[0005] Extended service life: Cross-linked cables are more resistant to aging and corrosion, thus extending their service life.

[0006] The irradiation process typically uses high-energy electron beams or gamma rays. The treated cables exhibit improved reliability and durability in many applications, such as automotive, power, and electronics.

[0007] Existing cable irradiation devices suffer from drawbacks such as large footprint, inconvenient assembly and production, and short service life of equipment and parts. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the defects of existing cable irradiation devices, such as large footprint, inconvenient assembly and production, and short service life of equipment and parts. The present invention provides an electron accelerator system that can form a self-shielding structure with a miniaturized electron accelerator, providing shielding protection for the wire wheel assembly, with better shielding effect and longer service life of the wire wheel assembly.

[0009] The present invention solves the above-mentioned technical problems through the following technical solution:

[0010] An electron accelerator system for cable irradiation is characterized in that the electron accelerator system includes a shielded shell, an electron accelerator, a cable irradiation platform, and a shielded door body.

[0011] The cable irradiation platform includes at least two cable take-up and release devices and a set of guide wheels.

[0012] The shielding door body and the shielding shell form an outer shielding cavity;

[0013] The cable on the take-up and release device is guided into the outer shielding cavity via a set of wire guide wheels;

[0014] The shielding shell has two first shielding bodies on the front side of the rear shell and two second shielding bodies on the rear side of the shielding door body. Both the first and second shielding bodies have wiring holes.

[0015] When the shielding door body and the shielding shell are installed, the first shielding body and the second shielding body form a central shielding cavity;

[0016] The electron beam exit of the electron accelerator is located inside the central shielding cavity, and the cable on the take-up and take-down device is guided by the wire wheel assembly to the area below the electron beam exit in the central shielding cavity.

[0017] Preferably, a shielding plate is provided behind the main body of the shielding door, the shielding plate is located between two second shielding bodies, the shielding plate is parallel to the main body of the shielding door, and the shielding plate and the main body of the shielding door are integrally formed.

[0018] Preferably, the shielding shell has a mounting hole at the front, and the edge of the mounting hole has a shielding protrusion. When the shielding door body is installed with the shielding shell, the back of the shielding door body fits against the front end of the shielding protrusion.

[0019] Preferably, the guide wheel assembly is located outside the central shielding cavity, and the guide wheel assembly includes several transverse guide wheels located on the rear side of the shielding door body.

[0020] Preferably, the cable irradiation platform is a mobile cable irradiation platform, which further includes a platform base. The bottom of the platform base is provided with a moving device. The shielding door body is vertically disposed at the rear end of the platform base, and the cable winding and unwinding device is disposed at the front side of the shielding door body of the platform base.

[0021] Preferably, the electron accelerator system further includes two auxiliary shielding doors, which are located on the front side of the shielding door body and on both sides of the platform base. There is a wiring gap between the two auxiliary shielding doors and a wiring clearance between the auxiliary shielding doors and the shielding door body.

[0022] Preferably, the guide wheel assembly includes a transverse guide wheel, which is fixed to the platform base on the rear side of the shielding door body. The transverse guide wheel is outside the central shielding cavity and guides the cable to move laterally inside the central shielding cavity.

[0023] Preferably, the electron accelerator system further includes a scanning box connected to the bottom of the electron accelerator, the scanning box being located within a central shielded cavity with the electron beam exit aligned with the cable between two transverse guide wheels.

[0024] Preferably, the bottom of the platform base is provided with a slide rail, and the platform base moves along the slide rail toward the shielding shell.

[0025] Preferably, the two first shields are located outside the two second shields.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0027] The positive and progressive effects of this invention are as follows:

[0028] This invention can be used in conjunction with a miniaturized electron accelerator to form a self-shielding structure, providing shielding protection for the guide wheel assembly, resulting in better shielding and a longer service life for the guide wheel assembly.

[0029] Specifically:

[0030] 1. Suitable for miniaturized electron accelerators;

[0031] 2. All equipment for cable loading, conveying, under-beam irradiation, and various technical processing is installed on a mobile platform;

[0032] It greatly saves space and investment costs of traditional cable irradiation systems and reduces losses during the cable irradiation process.

[0033] This application enables the miniaturization of cable irradiation systems when paired with miniaturized irradiation accelerators.

[0034] Unlike traditional cable irradiation, which is often done in large workshops, cable irradiation equipment can be integrated into a mobile work platform.

[0035] There is a vertical retaining wall in the middle of the platform. This retaining wall is mainly used as a shielding door, and it is also used for the installation and mounting of various cable auxiliary equipment.

[0036] The retaining wall divides the platform into inner and outer sections. On the inner side of the platform, facing the accelerator, a separate area in the center is designated for cable irradiation, with cable guidance and pretreatment areas on either side. The outer side of the platform houses the installation area for cable loading / unloading, tensioning devices, and other equipment.

[0037] Cables can be loaded or equipment can be maintained when the platform is removed, at which time the electron beam is in the off state.

[0038] When the platform is moved in, the retaining wall acting as a shielding door and the self-shielding outer shell of the main unit close, forming a safe shielding structure. In this way, when the electron beam is activated, operators can perform continuous operations in the area outside the platform. Attached Figure Description
