Abstract

The invention relates to the technical field of military radar, more specifically to a wind-resistant stabilizing device for a radar antenna array. One end of a steel wire rope is connected to a winch, and the other end of the steel wire rope is connected to the top end of the antenna array. Two ends of a ball screw are respectively provided with a support and a bearing, a slotted nut is arranged on the ball screw, a ball nut and a floating plate are both sleeved on the ball screw, and a disc spring is sleeved on the ball screw, the ball nut and the floating plate. A left drum cover is arranged at the left bearing, a right drum cover is arranged at the right bearing, and the left drum cover is fixedly connected to the right drum cover. A fixed stop is fixedly connected to the right drum cover. Two side sealing plates are respectively fixedly connected to the left drum cover and the right drum cover. The radar antenna array is obliquely pulled by the steel wire rope, so that the wind load is effectively resisted, the wind resistance is improved, stability is guaranteed, and the device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of military radar, in particular to a radar antenna front wind resistance stabilization device. Background technique [0002] In practical applications, in addition to the static and inertial loads of ice and snow and its own weight, radar also has dynamic loads from wind. The windward area of ​​a large radar antenna is large, and the wind load is relatively large, so it is particularly important to ensure the stability of the radar antenna against wind. At present, in order to ensure the stability of the radar antenna front against wind loads in China, it is mainly realized by changing the structure of the antenna front and adding external windproof facilities. [0003] There are several ways to change the structure of the antenna front: (1) Reasonably select the material of the antenna front and the structural form and component shape of the supporting back frame. For example, use orifice plates, grids o...
