Windproof and rainproof digital television signal communication antenna

Abstract

The invention relates to a windproof and rainproof digital television signal communication antenna, comprising a substrate, wherein four universal wheels are symmetrically mounted below the substrate, two negative pressure locking mechanisms are symmetrically mounted on the lower end face of the substrate, four struts are symmetrically arranged on the outer side of the upper end face of the substrate, an annular slide rail is mounted at the upper ends of the four struts, the four struts achieve the effect of uniformly supporting the annular slide rail, a rotating steel ring is mounted on the annular slide rail in a sliding fit manner, an inner gear ring is arranged on the inner wall of the rotating steel ring, the inner gear ring is connected with four drive mechanisms respectively, and the four drive mechanisms are symmetrically mounted on the upper end face of the substrate. The digital television antenna can realize an automatic windproof and rainproof function and a function of automatically adjusting the signal receiving tilt angle, and has the advantages of automatic orientation adjustment, negative pressure movable disassembly and assembly, automatic folding, wind and rain proofing, automatic adjustment on the signal receiving tilt angle, high receiving tilt angle precision, good signal receiving effect, high working efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a digital TV signal communication antenna capable of shielding from wind and rain. Background technique [0002] The antenna is a converter whose main function is to transform the guided wave propagating on the transmission line into electromagnetic waves propagating in the unbounded medium. Antennas are used in radio equipment as components for transmitting or receiving electromagnetic waves, and are widely used in radio communications, broadcasting, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems. Antennas can be divided into communication antennas, broadcast antennas, TV antennas, and radar antennas according to their uses, among which TV antennas are the most widely used. [0003] TV antennas can be seen everywhere in our lives. Since signal transmission towers are widely distributed in cities, there will be...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a digital TV signal communication antenna capable of sheltering from wind and rain, which can solve the problems of manual installation of digital TV antennas in mountainous areas, the need to manually adjust the direction of the TV antenna, the complicated installation and disassembly of the TV antenna, and the TV antenna. The coating of the antenna placed in the open air is easy to be corroded, the signal receiving performance is poor, the signal receiving inclination needs to be manually adjusted, the receiving inclination accuracy is poor, the signal receiving effect is poor, the operation is complicated, the labor intensity is high, and the work efficiency is low. The folding type of the digital motor antenna can be realized. The function of automatic wind and rain protection and automatic adjustment of signal receiving inclination does not require manual operation. It has automatic adjustment of TV antenna orientation, negative pressure movable disassembly and assembly of antenna, automatic folding of wind and rain protection, automatic adjustment of signal receiving inclination, and high accuracy of receiving inclination , good signal reception, easy operation and high work efficiency
