The depth of the deep well bin can reach 50 meters to 150 meters, and the diameter of the deep well bin is small (generally 3 meters to 8 meters, and is small relative to the depth). The mine production needs to realize intellectualization, the perception of various production situations is necessary, the level detection of a deep well bin is indispensable, related products are applied at home and abroad at present, and most of the products are radar level gauges. However, the deep well bin has a deep depth, a small diameter, and is located underground, so that the requirement on the emission angle of the radar level gauge of the level detection equipment is high, and the selection range is small. The emission angle of most radar level gauges is 8 degrees, and the emission angle of a small part of radar level gauges can be 4 degrees. The outstanding problem with current frequency-modulated radar level gauges using small transmission angles is that of angular adjustment, which in practice allows adjustment angles often of less than 5 °. The irradiation angle of the level indicator is slightly changed, so that the level indicator is easily irradiated on the bin wall, and the distortion of a level detection signal is directly caused.
