Description

Detachable lead screen wind device for nuclear power station radiation operation Technical Field The utility model relates to the field of nuclear power plant radiation operation, in particular to a detachable lead shield wind device for nuclear power plant radiation operation. Background The lead screen is used as a radiation protection key device and is widely applied to the scenes of medical radiation diagnosis and treatment (such as DSA interventional operation), nuclear facility inspection and the like. In particular, in the field of gamma-ray protection of nuclear power plants, the traditional lead shielding structure is required to meet the annual dose limit requirements specified by standards. However, the existing movable lead screen has the following technical defects when applied to nuclear industry scenes: 1. The adaptability of the multi-source radiation field is insufficient, namely, a multi-directional radiation source (such as a circumferential radiation field of a pressure container) exists in the nuclear power station, the existing single-type lead screen can only realize single-plane protection, so that a plurality of groups of independent screens are required to be arranged on site, and the occupation rate of the operation space is increased. 2. The modularized compatibility is poor, the existing lead shield of the nuclear power station mostly adopts lead skin with standard size, and the traditional screen adopts an integral lead plate welding structure and cannot be quickly matched with on-site storage lead materials.
