Quickly-erectable and withdrawable super large-scale meter-wave antenna

Abstract

The present invention relates to a quickly-erectable and withdrawable super large-scale meter-wave antenna and belongs to the radar array antenna manufacturing technical field. The quickly-erectable and withdrawable super large-scale meter-wave antenna is composed of a tower I, a tower II, a left antenna frame, a right antenna frame, a mechanical self-locking hydraulic push rod, a main tower locking mechanism, array folding reflection networks, unit antenna horizontal-to-vertical conversion mechanisms, a lifting bracket and a low-height antenna turntable; the tower I and the tower II are connected with each other through rotation pins and the mechanical self-locking hydraulic push rod; two sides of the tower II are fixedly provided with the left antenna frame and the right antenna frame; antenna frame folding and unfolding mechanisms are installed between the parallelogram frames of the left antenna frame and the right antenna frame; the tower I is connected with the lifting bracket through the main tower locking mechanism; and the lifting bracket is installed on the low-height antenna turntable through bolts. According to the quickly-erectable and withdrawable super large-scale meter-wave antenna, the pitching of an antenna array, and the locking and unlocking of the main tower locking mechanism can be realized, the large-scale array antenna can be quickly transferred, erected and withdrawn. The quickly-erectable and withdrawable super large-scale meter-wave antenna is stable and reliable in work. With the quickly-erectable and withdrawable super large-scale meter-wave antenna adopted, the problem that a super large-scale meter-wave antenna cannot be transferred can be solved.

Description

technical field [0001] The invention relates to a super-large meter-wave antenna that can be quickly erected and retracted, and belongs to the technical field of radar array antenna manufacturing. Background technique [0002] Modern warfare requires radars to see farther and farther away, and accordingly, the front antennas are required to be larger and larger; and radars are required to be able to see small targets such as aircraft and missiles, and correspondingly, the angles of front antennas are required to be able to change in real time On the other hand, in order to adapt to the requirements of modern warfare, it is required that the radar can quickly transfer positions and improve the anti-strike capability, which has become a pair of contradictions of the existing radar antennas; This requirement of modern radar cannot be met, so it is necessary to develop a super-large meter-wave antenna that can be erected and withdrawn quickly.
