The invention relates to a lever counter weight type gravity compensation device used for one-dimension deployed antenna ground deployment tests of spacecrafts such as satellites. The lever counter weight type gravity compensation device comprises a supporting assembly, a rotating plate assembly and a bottom plate assembly; the supporting assembly is composed of an adaptor, a rotating shaft, a plastic roller, a roller support, a pressure sensor and the like; the rotating plate assembly is composed of a rotating plate, a counter weight, rotating supports, a damper gear, an intermittent gear, bearings, a key and the like; the bottom plate assembly is composed of a bottom plate, bottom plate locking levers, sucked type electromagnets, a limiting pin, bottom plate guide rods and the like. When an antenna is deployed, the compensation device is in a sucked and combined state, and the sucked type electromagnets are powered on and sucked and combined with the rotating plate; after the antenna is deployed, the sucked type electromagnets are powered off, the rotating plate can rotate stably under the functions of the counter weight, the intermittent gear, the damper gear and the like, and finally the rotating plate supports the antenna to compensate the gravity. By means of the lever counter weight type gravity compensation device, the problem of gravity compensation of space antenna ground deployment tests is solved, the structure of the device is simple, the operation is convenient, the compensation force is adjustable, and no impact exists.
