Abstract

The invention relates to the technical field of microwave darkrooms, in particular to a flipping cover plate for a microwave darkroom pit. The flipping cover plate comprises a cover plate body, a first telescopic mechanism and a second telescopic mechanism; a cover plate wave-absorbing material layer covers the upper side face of the cover plate body, the two telescopic mechanisms are rotationallyconnected with the cover plate main body, by means of the telescopic height difference of the two telescopic mechanisms, when the flipping cover plate is opened, the cover plate body is lifted firstand then flipped, when the flipping cover plate is closed, rotation is conducted first, then falling is conducted, interference between the cover plate wave-absorbing material layer and the nearby ground wave-absorbing material layer is avoided, the partial wave-absorbing material layer does not need to be cut off due to reserved cover plate flipping space, both the cover plate main body and the surrounding ground can be covered by the wave-absorbing material layer, and opening and closing of the cover plate main body can be controlled conveniently.

Description

technical field [0001] The invention relates to the technical field of microwave anechoic chambers, in particular to an overturned cover plate for a microwave anechoic chamber pit. Background technique [0002] In the microwave anechoic room for RCS (Radar-Cross Section) measurement, there are usually pits for installing various equipment, such as pits for installing support systems that can move back and forth and be stored down, It is installed in the pits of the lifting platform and other movable turntables that send operators to high altitudes for target assumptions, in order to prevent the electromagnetic waves reflected by the pit walls and equipment in the pit from entering the quiet zone, and improve the reflection level of the quiet zone And the role of the background RCS, in the usual darkroom, the pit of the darkroom will be covered with a flip cover, and the top of the flip cover will be covered with a wave-absorbing material. [0003] In the current flip cover,...
