Abstract

Technical Field
[0001] The utility model relates to the technical field of radar level gauges, in particular to an anti-pollution radar level gauge. Background Art
[0002] Radar level gauge is a common level measuring instrument, a corrosion-resistant device used to measure liquid height. Its working principle is to use the reflection of radar signals between air and liquid for measurement. However, since the level gauge is greatly affected by the external environment during use, errors are prone to occur. For example, a radar level gauge with a bell mouth has contamination on the inner wall of the bell mouth. For example, a large number of water droplets remain on the inner wall of the bell mouth. At this time, the bell mouth is contaminated, which is very likely to affect the radar level gauge during measurement and cause large measurement errors. For this reason, we propose an anti-pollution radar level gauge to solve the above problems. Utility Model Content

[0017] See also Figure 1-Figure 3 In this embodiment: an anti-pollution radar level gauge, including a mounting plate 1, which can facilitate the installation of a radar level gauge body 7. The radar level gauge body 7 penetrating the mounting plate 1 is fixedly mounted on the top of the mounting plate 1, which can measure the position of the liquid, and the lower part of the radar level gauge body 7 located at the lower part of the mounting plate 1 is fixedly mounted with a bell mouth 3. The radar level gauge body 7 is located at the lower part of the mounting plate 1 and a gear ring 5 is installed on the outer ring. Three groups of scrapers 4 are evenly installed on the bottom surface of the gear ring 5. When the gear ring 5 rotates, it can drive the scraper 4 to rotate. The right side of the mounting plate 1 is rotatably connected with a rotating shaft 6 penetrating the mounting plate 1, and a gear 2 is installed at one end of the rotating shaft 6 located at the lower part of the mounting plate 1.
