Abstract

The invention relates to the technical field of ship equipment, and discloses a marine collapsible antenna base. The marine collapsible antenna base comprises a main body base, a base body and a driving piece, the base body comprises a sleeve rotationally assembled with the main body base and a telescopic column movably assembled in the sleeve in the axial direction of the sleeve, a guide groove extending in the axial direction of the sleeve is formed in the inner wall of the sleeve, and a guide column assembled with the guide groove in a guiding mode is arranged at the bottom of the telescopic column. When the ship passes through the height limiting area, the base body is rotated to be in a put-down state, the height of the antenna can be reduced, and the ship can pass through the heightlimiting area; in a severe weather environment, the base body is rotated to be in a put-down state, so that the antenna can be prevented from being damaged; meanwhile, the telescopic column of the base body is movably assembled in the axial direction of the sleeve, when the base body is rotated to be in a put-down state, the telescopic column can be contracted in the axial direction of the sleeve,the space occupied by the base body is further reduced, meanwhile, the overall structural strength of the base body is improved, and the situation that the antenna shakes and is damaged is avoided.

Description

technical field

[0001] The invention relates to the technical field of ship equipment, in particular to a ship-used reversible antenna base. Background technique

[0002] The antenna base is an important part of fixing and supporting the antenna on the ship. Generally, the antenna is arranged at the highest place on the ship to increase the efficiency of signal reception and transmission. Existing ships usually need to arrange a special base to fix the antenna. Since the antenna base on the ship is fixed, when the ship needs to pass through places with height restrictions such as docks and bridges, there will be problems due to the height of the antenna exceeding The height limit prevents the ship from passing through. Moreover, in severe weather environments such as typhoons and thunderstorms, the antenna remains erect for a long time, which may easily cause damage to it. Contents of the invention

[0003] The purpose of the present invention is to provide a reversible ...
