Embodiment Construction

[0027] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0028] see figure 1 , figure 2 and image 3 , the automatically unfolding electromechanical planar array antenna includes a planar array antenna and a turntable 7, and the planar array antenna is divided into two fronts along the height direction, that is, the upper side block 3 of the antenna and the lower side block 6 of the antenna, and the upper front side is 7.4×1.6m wide. 2 , Weight 1600kg, lower front width 7.4X height 2.2m 2 , weighing 2500kg.

[0029] A pitch drive mechanism 1 is respectively installed symmetrically on the division planes of the upper and lower fronts on the back of the antenna. The pitch drive mechanism 1 includes a frame 8, a motor 5, a reducer 4, a sliding screw pair, and a crank slider sector gear mechanism. . The two ends of leading screw 9 are installed in the frame 8 through bearings, there are matching nut...

Abstract

The invention relates to wireless detecting device antenna that is called planar array antenna. Its feature is that pitching driving mechanism and electric lock mechanism is separately set on the splitting plane of the two array surfaces. The pitching driving mechanism includes frame, motor, reducer, sliding master screw, crank block segment gear mechanism. And the electric lock mechanism includes lock motor, reducer, master screw, nut and locating pin. The antenna can automatically open out and withdrawing. It has advantages like small volume, low weight, high reliability, stepless speed regulation, etc. And the temperature range it can be used is from 40 degree centigrade below zero to 55 degree centigrade.

Description

technical field [0001] The present invention relates to wireless detection equipment antennas, in particular planar array antennas. Background technique [0002] In recent years, high-mobility radars are mainly limited to radars with small-aperture antennas. With the development of electronic technology and the needs of modern warfare, the ground medium and long-range three-coordinate military radar has widely used planar array antennas, and is developing in the direction of high maneuverability and rapid response. The caliber of the medium and long-range three-coordinate radar antenna is too large, and the antenna must be divided into blocks to meet the performance requirements of cross-country transportation. If the automatic erection / withdrawal is not realized, the divided radar antenna will inevitably spend a lot of manpower and time to assemble the antenna after the radar enters the position, so that the radar will lose its rapid response capability. The planar array ...
