Non-cooperative target satellite acquisition device and acquisition method

The invention discloses a non-cooperative target satellite acquisition device and an acquisition method, and belongs to the technical field of aerospace. The non-cooperative target satellite acquisition device includes an outer shell, two four-link capturing pawl mechanisms, four horizontal locking mechanisms, a screw rod and a controller; the two four-link capturing pawl mechanisms are arranged in the outer shell face to face, and the lower parts thereof are fixedly connected with an installing bottom plate; the lower end of the screw rod crosses through the installing bottom plate, and the lower end thereof is connected with a driving mechanism; four horizontal locking mechanisms are respectively located at outside of the two four-link capturing pawl mechanisms, and every two horizontal locking mechanisms are installed on the upper part of the outer shell; both sides of the upper part of the four-link capturing pawl mechanisms are respectively equipped with pressure lever mechanisms; when the four-link capturing pawl mechanisms are descended, the pressure lever mechanisms compress the horizontal locking mechanism to horizontally glide towards inside; the top part of the outer shell is equipped with a photoelectric sensor, and the photoelectric sensor and the driving mechanism are electrically connected with the controller. The non-cooperative target satellite acquisition device is widely applied to the acquisition of various space crafts, and the non-cooperative target satellite acquisition device is wide in application range, big in tolerance, quick in response speed, high in reliability, and others.
