Description

Technical Field

[0001] The utility model belongs to the technical field of nuclear environment cameras, and particularly relates to a radiation-resistant binocular positioning camera structure. Background Art

[0002] The reactor pressure vessel (RPV), also known as the reactor pressure vessel, is a sealed container that houses the nuclear reactor and withstands its immense operating pressures. It is a critical component of a pressurized water reactor (PWR) nuclear power plant. Its manufacturing is characterized by high technical standards, significant difficulty, and a long production cycle. Furthermore, it is irreplaceable and must be guaranteed to be absolutely safe and reliable throughout the plant's 40-year lifespan. The RPV secures and contains the reactor core and its internals, confining the fission reaction of the nuclear fuel within a sealed space. Together with the primary circuit piping, it forms the pressure boundary for the high-pressure coolant and serves as a secondary barrier to prevent the release of radioactive materials, making it crucial to nuclear power plant safety.

[0003] To address this situation, nuclear power plants typically place radiation-resistant cameras inside pressure vessels to monitor internal operating conditions and foreign matter. Chinese patent CN216774838U discloses a radiation-resistant camera for nuclear environment imaging. The camera comprises a camera body, a lens refraction structure, and a core heat dissipation structure, both mounted on the camera body. The lens refraction structure includes a base connector, an upper protective cover connector, a mirror vertical adjustment bracket, a steering wheel fixing bracket, and a steering wheel. Traditional radiation-resistant cameras only provide simple monitoring functions, are unable to accurately locate objects, and have difficulty identifying the shape of some metal surfaces.
