Description

Ray safety cabinet labyrinth structure protection device with ray not prone to leakage

Technical Field

The utility model relates to an ionizing radiation protection field especially relates to a ray safety cabinet labyrinth structure protection device that ray is difficult for leaking.

Background

X-ray technology plays an increasingly important role in everyday life and in scientific research. In recent years, X-ray based detection and imaging techniques have found increasing use in the fields of industry, medicine, scientific research, and the like. However, the energy carried by the X-rays is high, causing ionizing radiation when passing through air. When any ionizing radiation irradiates an object, the irradiated object will absorb all or part of the energy of the ionizing radiation. For human body, excessive irradiation causes the function of cells in the body to be reduced, thereby inducing various diseases. Therefore, the effective X-ray protection method not only can protect the health of operators and the public, but also can promote the popularization and application of the X-ray technology.

An X-ray source safety cabinet (safety cabinet for short) is a shielding device for protecting personnel and equipment from harmful X-ray radiation generated by a non-shielding X-ray source, and the protection level of the X-ray source safety cabinet is in accordance with appropriate international standards and laws. The safety cabinet must provide an access for the experimental equipment and the X-ray source service operation through a hatch and a door, and a radiation-proof labyrinth structure for the feeding device of cables and cooling water pipes to enter and exit the cabinet body. These labyrinth structures are used to prevent any leakage of directed or divergent X-rays. At present, in the aspect of processing a labyrinth structure, in the radiation shielding practice of entering and exiting cable holes and the like, the traditional processing technology still has the risks of exceeding the standard of X rays and leakage around the labyrinth structure, and the X rays leak from an outer side steel plate layer on the periphery of a threading sleeve.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a ray safety cabinet labyrinth structure protection device that ray is difficult for leaking.

The utility model discloses an innovation point lies in the utility model discloses a set up a lid around the threading cover, can avoid leaking from the outside steel deck department in the labyrinth lid of the ray that comes out of threading cover department, guaranteed operating personnel and public health.

In order to realize the purpose of the utility model, the technical proposal of the utility model is that: the utility model provides a ray safety cabinet labyrinth structure protection device that ray is difficult for leaking, includes the safety cabinet body, be equipped with the threading cover on one of them wall body of safety cabinet body, be equipped with the labyrinth lid that is used for covering the threading cover on the safety cabinet body, the wall body at threading cover place includes inboard shielding layer and outside steel deck, be equipped with a plurality of braced frames between inboard shielding layer and the outside steel deck, the threading cover material is shielding material, threading cover and inboard shielding layer fixed connection, still be equipped with the spacing frame of round between inboard shielding layer and the outside steel deck, spacing frame is around outside the threading cover, be equipped with the lid in the spacing frame, be equipped with the through-hole that is used for passing the threading cover on the lid, lid and spacing frame, braced frame height, the labyrinth lid is located the marginal range of lid. The problem that X-rays leak and exceed standards around a labyrinth structure is effectively solved, and the health of operators and the public is guaranteed.

The utility model has the advantages that:

1. the utility model discloses a set up a lid around the threading cover, the outside steel deck department that can avoid the ray that comes out from the threading cover from the labyrinth cover leaks, has guaranteed operating personnel and public health.
