Embodiment Construction

[0013] In order to better understand the purpose, structure and function of the present invention, a pusher-type satellite large-field-of-view scanning execution device of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, the push rod type satellite large field of view scanning execution device includes a satellite connecting plate 1 , a lower connecting mechanism 2 , a displacement pair 3 , an upper connecting mechanism 4 , a flywheel connecting plate 5 and a flywheel 6 .

[0015] To install the satellite connection board 1 on the satellite installation surface, it is required that the normal direction of the satellite connection board 1 is parallel to the optical axis direction of the satellite imaging payload. Then the displacement pair 3 is connected to the satellite connection plate 1 through the lower connection mechanism 2 . Connecting mechanism 4 is installed then. Repeat th...

Abstract

The invention discloses a push rod type satellite large-view-field scanning execution device. The device comprises a satellite connecting plate, a lower connecting mechanism, a displacement pair, an upper connecting mechanism, a flywheel connecting plate and a flywheel. A push rod type satellite large-view-field scanning executing mechanism adopts a step-by-step connection mode, a satellite connecting plate is arranged at a bottommost part, and the push rod type satellite large-view-field scanning executing mechanism is connected to a satellite with an imaging load through the satellite connecting plate. The satellite connecting plate is connected to the kinematic pair through the lower connecting mechanism, the kinematic pair is connected to the upper connecting mechanism, the upper connecting mechanism is connected to the flywheel connecting plate, and finally the flywheel assembly is installed on the flywheel connecting plate. Compared with traditional satellite large-view-field scanning execution, a push rod type satellite large-view-field scanning execution mechanism has advantages of being small in size and easy to adjust, and large-view-field scanning execution difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of satellites, and in particular relates to a pusher type satellite large-field-of-view scanning execution device. Background technique [0002] Existing actuators for large field of view scanning of satellites usually use moment gyroscopes to control the pointing of satellites to achieve large field of view scanning. However, the torque gyroscope is usually connected with the flywheel motor by a conductive slip ring, which affects the reliability of the system, and the direction of the flywheel is adjusted through the external frame of the torque gyroscope. The dynamic characteristics of this method are limited by the torque of the external frame to adjust the motor. In practical applications, the scanning of the large field of view is mostly in the direction of the ground, and the full-circle motion of the moment gyro is redundant at this time, which has the disadvantages of poor dynamic characteristics an...
