Abstract

The invention relates to an anti-radiation camera shooting device comprising an anti-radiation key shielding device and a high-radiation shielding protection device, wherein the anti-radiation key shielding device comprises ZF6 lead glass I, a movement, a cylinder I, a back end cover I and a cable connector; the high-radiation shielding protection device comprises ZF6 lead glass II, a cylinder II and a back end cover II; the cylinder I is provided with a cylinder pin I and a cylinder pin II which are respectively positioned with a pin groove I and a pin groove II in the cylinder II and are tightly pressed by a thread ring. According to the anti-radiation camera shooting device, the cylinder I of the anti-radiation key shielding device is filled with lead balls to focally shield gamma ray and damages of neutrons to a camera CMOS (Complementary Metal-Oxide-Semiconductor Transistor) and a circuit microprocessor; the whole structure is cylindrical and no devices, parts or standard parts are arranged on the surface, so that the anti-radiation camera shooting device is suitable for use in a nuclear environment condition; and meanwhile, the whole structure is reasonably sealed and the protection grade can reach IP68; therefore, the anti-radiation camera shooting device is suitable for monitoring operation conditions of fuel workshops of nuclear power stations and equipment in nuclear islands.

Description

technical field [0001] The invention belongs to the field of video monitoring devices, and relates to a radiation-resistant camera device, which is especially suitable for monitoring the operation conditions of fuel workshops and nuclear island equipment in nuclear power plants. Background technique [0002] Nuclear power is a new generation of clean energy, but its safety is also very important. Once a leak occurs, it will be extremely harmful. The nuclear radiation environment is one of the worst environments currently existing. Instruments working in the nuclear radiation field must have strong radiation resistance and anti-radiation functions. The anti-radiation camera device can display the things in the heavy radiation field on the TV in real time. The screen is for the staff to observe. It can help the nuclear power plant to conduct safety inspections at ordinary times, and assist in eliminating risks in case of accidents. It has become one of the necessary components...
