Description

Technical Field

[0001] The utility model relates to the technical field of precipitation measurement, in particular to a parabolic antenna for a light rain radar. Background Art

[0002] The light rain radar is a low-power frequency-modulated continuous wave Doppler radar that judges rainfall conditions based on the relationship between raindrop size and scattering cross-section, and raindrop size and falling rate. Compared with traditional ground-based rain measuring devices, the light rain radar has high sensitivity and high temporal and spatial resolution. The light rain radar consists of a support leg, a crank arm, a parabolic antenna, and a host control unit. In order to ensure a light structure, the light rain radar adopts a single crank arm design, which makes the lowest point of the parabolic antenna face the wall. Therefore, when the rainfall and snow are heavy in winter, after the rain and snow fall on the parabolic antenna, the parabolic antenna's built-in heating device will melt the snow on the parabolic antenna. The melted snow water flows along the parabolic antenna to the lowest point, and then easily forms ice on the crank arm and cable, causing the light rain radar signal transmission to fail, affecting the accuracy of meteorological monitoring.

[0003] A Chinese utility model patent with publication number CN214754098U discloses an anti-icing device for a light rain radar. This utility model adopts a design of a first crank arm and a second crank arm, so that snow accumulated on the parabolic antenna will not pass through the first crank arm and the second crank arm after melting and will fall directly to the ground. Because the legs are independently supported, there is a possibility of breakage in windy weather, which will lead to low stability of the device. Utility Model Content

[0006] As a further improvement of the above scheme, the rotating mechanism includes a protective cover installed at the bottom end of the mounting seat. The protective cover is a truncated cone structure. A groove is opened at the bottom end of the protective cover. A fixed cylinder is fixedly connected to the middle position of the top end of the groove. The support column extends into the interior of the fixed cylinder, and the support column is rotatably connected to the fixed cylinder. A worm gear is provided on the outer wall of the fixed cylinder. A motor is installed inside the groove.
