Sensor or communications array, maybe
This was probably part of the diffuser of a blow drier.[1] The other part is shaped somewhat like the UFO from The Invaders tv series. (Watch this space, as the saying is.) It will be a piece of scatter terrain, useful as cover, or an objective, maybe a communications or sensor array, or maybe those pylons go far underground and are extracting energy (even if it's just a temperature differential).
