A compact radar antenna turntable

Abstract

The invention relates to a compact radar antenna turntable, comprising an azimuth adjustment unit and a pitch adjustment unit. The azimuth adjustment unit includes a casing, a disc motor, a gear transmission mechanism, an output flange, a manifold ring, and an encoder; the gear transmission mechanism includes a driving gear, a variable speed gear assembly, and a driven gear, and the driving gear is fixedly installed on the output shaft of the disc motor. It is connected with the driven gear through the speed change gear assembly. The driven gear is fixedly sleeved on the outside of the output flange, the lower end of the output flange is rotatably connected with the outer casing, the upper end extends out of the outer casing, and the confluence ring is arranged in the hollow of the output flange. In the cavity, the encoder moving plate is fixedly connected with the lower surface of the driven gear. The pitch adjustment unit includes a support base, a pitch axis, a clamp for installing the radar antenna, and a locking mechanism; the support base is fixedly installed on the upper end of the output flange, and both ends of the clamp are hinged to the support base through the pitch axis, and the locking mechanism is used for In the pitch attitude of the fixed hoop.

Description

technical field [0001] The invention relates to a compact radar antenna turntable. Background technique [0002] Radar antenna turntables are often used in field surveying and mapping equipment to complete accurate target tracking and data measurement by driving the radar antenna to adjust the attitude. The radar antenna turntable generally requires small size, light weight, low energy consumption, and high positioning accuracy. At the same time, in order to adapt to the harsh weather conditions in the field, the turntable also needs to have strong anti-overturning ability and high protection level, and has the ability to be compatible with other equipment (antenna, tripod) interface for quick installation. Patent CN 109149111A discloses a direct-drive radar turntable, which adopts the method of directly driving the output shaft of a torque motor. The structure is relatively simple, but it is difficult to meet the requirements of the portable turntable on size, weight and p...
