The rear wall of the hot chamber is provided with a shielding door, and equipment can be accessed, cleaned, installed and disassembled when necessary; the top is provided with a lamp box for illumination, a transport trolley is arranged for transporting articles to enter and exit the hot chamber; the hot chamber is ventilated by an exhaust system, the hot chamber is kept to work under negative pressure, and the exhausted wind passes through a high-efficiency filter to remove radioactive aerosol and dust; the side wall is provided with an electric connector, a process connector and the like according to the requirement of equipment in the hot chamber. Generally, in order to facilitate testing, operation, and observation of the state of radioactive substances in a hot chamber, an observation device is disposed inside the hot chamber, and the observation device is currently as follows:
1. the camera is arranged in the hot chamber, and when the camera is not used, the camera is placed in the lead box by utilizing the power mechanical arm in the hot chamber, so that the radiation damage of radiation substances in the hot chamber is avoided. Although the camera is placed in the lead box to shield external radiation when not in use, the camera is taken out of the lead box by the power manipulator, so that the surface of the camera cannot be polluted, and when the camera is put in the lead box, polluted radioactive substances can be put in the lead box together to irradiate and damage the camera in the lead box. Meanwhile, the camera operated by the power manipulator occupies limited power manipulator resources, so that the power manipulator cannot operate while observing. And the power manipulator and the camera are of a split structure, and the circuit is easy to wind, so that the circuit is damaged and other faults are caused.

Although the observation range is improved to a certain extent, the camera cannot rotate and can only translate, a dead angle still exists in observation, and any area in the hot chamber cannot be observed.
Although all of the above devices are capable of performing the function of observing the interior of the hot chamber, these instruments have the drawback that: the wall thickness of the hot chamber has large dead angles in the observation process, the observation range is limited, and large-range observation cannot be realized; direct visual observation cannot be carried out, the hot chamber distance and the space size cannot be accurately measured, and inconvenience is brought to development of experimental research.
