Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric turntables, in particular to a dehumidifying load cabin of a photoelectric turntable. Background Art

[0002] For the optoelectronic turntable, since various optical devices are integrated inside the payload cabin, the internal air needs to be kept dry for a long time. In order to achieve this goal, the current main work is to replace the air inside the payload cabin with dry nitrogen, and dehumidify the interior of the cabin with the desiccant inside the desiccant box.

[0003] Chinese utility model patent (authorization announcement number: CN219249018U name: an optoelectronic turntable with an embedded Kude optical path) The azimuth U-shaped frame of the turntable can move in azimuth under the drive of the azimuth motor in the turntable base, and the optoelectronic payload cabin can move in pitch under the drive of the pitch motor on the azimuth U-shaped frame; the turntable base has a hollow cavity, and the azimuth U-shaped frame is a shell structure; the laser beam is incident from the light entrance hole on the side wall of the turntable base, and passes through the first Kude reflector installed in the cavity of the turntable base, the second Kude reflector, the third Kude reflector, and the fourth Kude reflector installed in the azimuth U-shaped frame shell in sequence, and the fifth Kude reflector installed in the optoelectronic payload cabin is turned, and finally emitted through the emission window of the optoelectronic payload cabin; the optoelectronic load visual axis in the optoelectronic payload cabin and the laser beam emitted from the emission window share the same optical axis. The utility model can simultaneously perform image recognition and locking of flying objects near the airport route, as well as accurately interfere with and drive them away. However, according to the current design, the desiccant box is often installed on the cabin before the internal gas of the cabin is replaced. During the replacement process, the desiccant box has already begun to absorb moisture from the cabin gas, which seriously affects the service life of the desiccant box. In addition, when the desiccant box is replaced later, after the desiccant box is removed from the cabin, the entire cabin will be connected to the outside air. After replacing the desiccant box, the cabin gas needs to be replaced again, and this cycle causes a waste of time and cost. Utility Model Content
