Signal receiving antenna with automatic dust removing function

Abstract

The invention discloses a signal receiving antenna with an automatic dust removing function. The antenna comprises a signal receiving antenna body. A fixed base is welded to a bottom center of the signal receiving antenna body and is rotatingly connected to a supporting bracket through a first rotating connection frame. A support screw rod is embedded and screwed into one side of the top of the supporting bracket, and the top end of the support screw rod is rotatingly connected to the fixed base at the bottom of the signal receiving antenna body through a second rotating connection frame. A high-frequency head is fixed to an outer side of the signal receiving antenna body through a high-frequency bracket, and a dust removing fan is fixed to an outer side of the high-frequency bracket through a triangular support frame. In the invention, firstly, dust at the surface of the high-frequency head is periodically blown through the dust removing fan, thus the signal receiving intensity of thesignal receiving antenna body can be enhanced, and the practicability of the signal receiving antenna body is enhanced.

Description

Technical field [0001] The present invention relates to the technical field of signal receiving antennas, in particular to a signal receiving antenna with automatic dust removal function. Background technique [0002] The antenna is a kind of converter that transforms the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in the use of electromagnetic waves to transmit energy, non-signal energy radiation also requires an antenna. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving ...

AI Technical Summary

Problems solved by technology

[0003] The traditional signal receiving antenna has a relatively simple structure and lacks auxiliary protection measures, which easily affects the signal receiving strength and shortens the service life.
