Ventilating structure for air cooling accelerator shielding container and container/vehicle check equipment

Abstract

The invention provides a ventilating structure for an air cooling accelerator shielding container and self-walking container/vehicle check equipment. The ventilating structure comprises a shell with a containing cavity, a first air hole and a second air hole, a shielding body with a mounting cavity, a third air hole and a fourth air hole and an airflow device. The shielding body is arranged in the containing cavity, and a betatron is mounted in the mounting cavity. The ventilating structure is designed for the shielding container, the first air hole, the third air hole, the mounting cavity, the fourth air hole and the second air hole are sequentially communicated to form a ventilating channel, the airflow device is mounted at the position of the first air hole and/or the second air hole, the airflow device is started to enable air in the ventilating channel to flow, and air exchange is carried out for the mounting cavity to reduce the temperature in the mounting cavity and cool the betatron. Therefore, the temperature rising speed of the betatron is reduced, and the continuous work time of the equipment is prolonged.

Description

technical field [0001] The present invention relates to the field of ray scanning inspection equipment, more specifically, to a ventilation structure for an air-cooled accelerator shielding container, and a self-propelled container / vehicle inspection device with the shielding container. Background technique [0002] In the prior art, the betatron of the ray scanning inspection equipment is installed in a shielded container, and the shielded container is provided with a ray outlet. Among the rays generated by the betatron, those in the pre-direction (that is, aligned with the ray outlet on the shielded container) ) useful rays can be emitted from the ray outlet, and the rest of the useless rays are shielded by the shielding container. The shielding container is composed of an upper cover and a box body. The betatron is installed in the cavity of the box body. After the upper cover and the box body are closed, the cavity is basically airtight, causing the temperature of the be...

AI Technical Summary

Problems solved by technology

The shielding container is composed of an upper cover and a box body. The betatron is installed in the cavity of the box body. After the upper cover and the box body are closed, the cavity is basically airtight, causing the temperature of the betatron to rise rapidly when the betatron is working. When the temperature rises to a certain level, it is prone to failure and may even be damaged. Therefore, the existing ray scanning inspection equipment must be shut down for a short period of time after continuous operation.
