Fine adjustment type efficient antenna capable of preventing damage caused by floating object crushing in severe weather and prevention method

Abstract

The invention discloses a fine-tuning high-efficiency antenna capable of preventing floating objects from being hit in severe weather and a prevention method, belongs to the technical field of fine-tuning antennas, and aims to solve the problems that broken stones on the ground can be rolled up due to wind power, the antenna in a severe environment is easily hit by the broken stones, normal operation of the antenna is affected, and even signal transmission operation of the antenna is directly interrupted. And if a protection device is directly additionally arranged at the periphery of the antenna, the signal receiving performance of the antenna is easily influenced. According to the invention, the shield plate swings to the right upper end of the fine-tuning antenna member to form a shield cover and presents an inclined state, and at the moment, the fan faces the right upper end of the fine-tuning antenna member to apply wind power to the fine-tuning antenna member from top to bottom, and the shield cover shields the fine-tuning antenna member in severe weather; the rotating shaft points of the traction swing rod and the cover plate are perpendicular to each other, so that the moving range of the cover plate and the traction swing rod is enlarged, under mutual auxiliary cooperation, flying birds are repelled daily, and the functionality of the cover plate is improved.

Description

technical field [0001] The invention relates to the technical field of fine-tuning type antennas, in particular to a fine-tuning type high-efficiency antenna capable of preventing damage from floating objects in bad weather and a prevention method. Background technique [0002] Common antennas include mobile base station antennas, broadcast antennas, radar antennas, WIFI antennas and mobile phone antennas. When there is alternating current flowing on the wires, electromagnetic wave radiation can occur. The induction field is reversed, so the radiation is very weak; when the two wires are opened, the induced electric fields generated by the two wires are superimposed in the same direction, so the radiation is strong, and the radiation ability is related to the length and shape of the wire. [0003] The antenna is a device that radiates and receives radio waves, but in high-intensity wind and rain, the wind will roll up the gravel on the ground, which is easy to cause the ante...
