Antenna protection cover supporting and clamping device

Abstract

The invention provides an antenna protection cover supporting and clamping device, and belongs to the technical field of near space environment ground simulation. The problem that an existing supporting and clamping mechanism cannot meet the requirement for supporting and moving of a near-space high-speed target antenna protection cover is solved. The device comprises a translation mechanism, a rotating mechanism and a clamping mechanism, the translation mechanism is connected with the rotating mechanism, the rotating mechanism is connected with the clamping mechanism, the clamping mechanism is connected with an antenna protection cover, the translation mechanism drives the antenna protection cover to translate in the radial direction, and the rotating mechanism drives the antenna protection cover to rotate in the circumferential direction. The clamping mechanism comprises a connecting plate, a lower clamping plate, an upper clamping plate, bottom plates and radial moving assemblies; the multiple bottom plates are evenly distributed on the connecting plate in the circumferential direction, each bottom plate is provided with the corresponding radial moving assembly, the radial moving assemblies are connected with the lower clamping plate, and the upper end of the lower clamping plate is connected with the upper clamping plate. The clamp is mainly used for supporting and clamping the antenna protection cover.

Description

technical field [0001] The invention belongs to the technical field of near-space environment ground simulation, and in particular relates to a supporting and clamping device for an antenna protective cover. Background technique [0002] Near space is the space area 20-100km from the ground, between satellites and aviation flight areas, not only the necessary place for spacecraft to and from outer space, but also the flight corridor for hypersonic vehicles. As an important carrier for the development and utilization of near space, high-speed aircraft in near space will open up new areas of human activities. The characteristics of high speed, low altitude, long endurance, and reusability of high-speed aircraft in near space make it an important transportation carrier for flexible access to near space, rapid global arrival, and space travel. It has become the focus of research by major scientific and technological countries . [0003] When the aircraft flies at hypersonic sp...
