Embodiment Construction

[0019] The specific implementation, structure, features and effects provided by the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figure 1~2 The shown underwater small-sized radiation-resistant camera device includes a housing, a camera installed in the housing, an LED lighting lamp and a circuit board. The housing is composed of a lens cap, a cylinder and a rear end cover. The housing is The pressure-resistant watertight casing has a total length of 190mm and is divided into a lens cap of φ35mm, a cylinder of φ31mm and a rear end cap of φ31mm. The lens cap can be replaced. The lens cap 1 and the lead-containing radiation-resistant optical glass sheet (ZF7) 8 Compression fit, threaded to one end of the cylinder 2, the other end of the cylinder is threaded to the rear end cover 3, the rear end cover is connected to the cable joint 7, and the cable joint is connected to the cable 6, whe...

Abstract

The invention relates to an underwater small radiation-resistant photographing device. A shell consists of a lens cap, a cylinder and a rear end cover; the lens cap is in force fit with a lead-containing radiation-resistant optical glass sheet and connected to one end of the cylinder through threads; the other end of the cylinder is in threaded connection with the rear end cover; the rear end cover is connected with a cable joint; the cable joint is connected with a cable; four light emitting diode (LED) illumination lamps are uniformly arranged around a camera; a first sealed chamber and a second sealed chamber which are respectively independent are arranged in the cylinder; the camera and the LED illumination lamps are arranged in the first sealed chamber, a circuit board is arranged in the second sealed chamber, and all joints are sealed by adopting O-shaped rings; and according to the radiation condition, a gamma or neutron radiation shielding module layer is arranged outside the shell, and a third sealed chamber is arranged in the gamma or neutron radiation shielding module layer. By integrated design of auxiliary illumination and the camera, installation and operation of a system are facilitated, the moving condition of an underwater refueling machine of a nuclear power plant in the water is learnt, and help is provided for underwater positioning of the refueling machine.

Description

technical field [0001] The invention belongs to the field of video monitoring devices, and relates to a small underwater radiation-resistant camera device, which is especially suitable for monitoring the operation of fuel and equipment in nuclear power plants. Background technique [0002] Once the nuclear fuel used in nuclear power is "ignited", in addition to generating huge heat energy for power generation, it also releases extremely strong radioactive substances that threaten the personal safety of workers. The TV camera system is an important auxiliary tool for people to monitor the operation of fuel and equipment in nuclear power plants. It can display the things in the heavy radiation field on the TV screen in real time for the staff to observe. The nuclear radiation environment is one of the worst environments that exist at present, and the TV systems working in this environment will be damaged and destroyed to varying degrees. A large amount of energy released by ...
