The invention provides a transmitter antenna with a defrosting and deicing function. The periphery of a dipole antenna and the periphery of a connecting rod are sleeved with a protective sleeve; the protective sleeve is divided into a heat isolation layer, an electric heating wire layer for heating, a heat-dissipating layer for heat dissipation, and a heat-collecting layer for heat collection, wherein the heat isolation layer, the electric heating wire layer, the heat-dissipating layer and the heat-collecting layer are distributed sequentially from inside to outside; a plurality of oblique supporting rods are fixed on the top end of a mounting rod; the end portions of the oblique supporting rods are connected together and support a solar heat collector; a thermal insulation water pipe is arranged in the mounting rod and the oblique supporting rods; and one end of the thermal insulation water pipe is connected with the solar heat collector, and the other end of the thermal insulation water pipe is communicated with the interior of the heat-collecting layer. The exterior of the transmitter antenna is provided with the protective sleeve, so that ice and frost can be isolated; an electric heating mode and a solar heating mode are adopted to perform deicing and defrosting; and solar energy deicing can assist in saving energy and is convenient and practical, and therefore, hidden dangers of manual cleaning can be eliminated.
Description
technical field [0001] The invention belongs to the technical field of transmitter antennas, in particular to a transmitter antenna with defrosting and deicing functions. Background technique [0002] In the broadcasting and television system, the transmitting antenna is an important part and plays a very important role. When ice is formed on the surface of the radome, electromagnetic waves will be scattered on the surface of the ice, which will affect the radiation characteristics of the antenna and directly affect the signal stability and coverage area of the service area. At the same time, electromagnetic waves will reflect on the surface of the ice layer, causing transmission loss, directly affecting the radiation power, and increasing the standing wave ratio of the antenna voltage. The increase in the standing wave ratio may cause damage to the transmitter and affect the entire transmission system. Therefore, in order to ensure the all-weather working performance, se...
