Problems solved by technology

[0003] Traditional radiation protection shielding devices, when used, generally place two matching and sealed shells directly around the cyclotron to achieve shielding. This operation can achieve effective shielding, but in actual use, the operator does not change Quickly and flexibly adjust the position of the shielding device, resulting in very cumbersome and inconvenient operations such as the maintenance of the cyclotron, and generally a mechanism has only one shielding position, which cannot meet continuous use

Abstract

The invention discloses a radiation protection shielding device for a cyclotron, which relates to the technical field of cyclotrons and comprises a bottom plate and column seats. The column seats are arranged on two sides of the bottom of the bottom plate, mounting columns are arranged on the bottom plate on one sides of the column seats, a top plate arranged at the top of the mounting columns, the shielding mechanisms are arranged on two sides of the top plate, the shielding mechanism comprises a mounting block, shielding covers are arranged at the bottom of the mounting block, the shielding covers on the two sides of the top plate are arranged at the top and the bottom of the mounting block respectively, an annular groove is formed in a column base below the shielding covers, a shielding cylinder is arranged in the annular groove, a rotating column is fixedly arranged on the mounting block in a penetrating mode, the two ends of the rotating column extend into the mounting groove, and the linkage assembly is arranged on the side wall of the top plate on one side of the transmission assembly. In the operation process, the transmission assembly drives the shielding cover to intermittently turn over through the transmission gear, meanwhile, the linkage assembly drives the mounting cylinder to move, rapid shielding of the cyclotron is achieved, use is more flexible, and operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of cyclotrons, in particular to a radiation protection shielding device for cyclotrons. Background technique [0002] With the continuous development of science and technology, various radionuclide drugs are widely used in scientific research, medicine, etc. Due to the increasing demand for radionuclide drugs, the demand for cyclotrons, the core equipment for radionuclide drug production, is also increasing. getting bigger. At present, the cyclotrons used in China are basically products imported from abroad or technology of foreign-funded enterprises. In addition to solving the core technology and production technology of cyclotrons, domestic companies must also provide shielding for the entire equipment. Completely solve the problem. [0003] Traditional radiation protection shielding devices, when used, generally place two matching and sealed shells directly around the cyclotron to achieve shielding. Thi...
