Automatic ice melting device of antenna feeder of relay station

Abstract

The invention relates to a device for removing ice or snow from an antenna or a feeder cable, in particular relates to an automatic ice melting device of an antenna feeder of a relay station. The device comprises a power circuit, a voltage stabilization control circuit, an ambient temperature detection circuit, an icing detection circuit, a signal warning circuit and a heating circuit and is structurally characterized in that the ambient temperature detection circuit, the icing detection circuit and the signal warning circuit are electrically connected in sequence; the control triggering end of the icing detection circuit is electrically connected with the heating circuit; a heated wire in the heating circuit is a carbon fibre heated wire mounted on the antenna feeder; and an induction switch contact of the icing detection circuit is mounted on the antenna feeder. The device provided by the invention has the advantages that the reliable operation of the automatic ice melting device is ensured by using double induction and judgment structures of the ambient temperature detection circuit and the icing detection circuit, ice melting is achieved and the dangerous case is solved promptly, and the ice melting through heating and receiving and dispatching signals by the antenna feeder can be carried out simultaneously by using the carbon fibre heated wire as the carrier for melting ice.

Description

technical field [0001] The invention relates to a device for removing ice or snow from an antenna or a feeder cable, in particular to an automatic ice-melting device for an antenna feeder in a relay station. Background technique [0002] In the prior art, a water regime telemetry relay station is installed in the north or at a place with a higher altitude for remote monitoring of water regime data. However, due to extreme weather, the antenna feeder of the relay station often freezes, and when the icing is severe, the antenna feeder is likely to be broken, which further leads to a large-scale interruption of water regime data at the water regulation central station, affecting the automatic water regime monitoring and reporting system safe and reliable operation. Moreover, during the time period when the failure occurred, the traffic was extremely inconvenient due to the impact of the climate, especially the need to go up the mountain for repairs, which brought great safety ...

AI Technical Summary

Problems solved by technology

However, its shortcomings are as follows: 1. Since the general heating device is directly based on the external temperature as the factor that causes heating, this will cause the heating device to start at a low temperature but not frozen state, which will affect the safety of the antenna and feeder. Normal use also brings adverse effects, and it is easy to affect the service life of the antenna feeder; 2. The heating wires used are all metal or similar conductive materials, so they will affect the electromagnetic waves of the relay station to send and receive signals, resulting in the relay station not working properly
