Description

Technical Field

[0001] The utility model belongs to the technical field of radar level gauges, and particularly relates to a rotary radar level gauge. Background Technique

[0002] In industry, there are many types of instruments for level measurement. However, at present, the most commonly used instrument in the market is the radar level gauge. For different measurement scenarios, different models of radar level gauges are used. For example, in granaries, coal bunkers, storage tanks, etc., in an environment with a large amount of dust, a suitable model needs to be selected according to the measurement environment and the measured medium.

[0003] For a general radar level gauge, when it is used in a measurement site with a relatively high height and the measurement angle of the radar level gauge needs to be adjusted frequently, although the general radar level gauge can be adjusted arbitrarily, it needs to be manually adjusted, which is relatively troublesome and labor-consuming. In view of this, we propose a rotary radar level gauge. Content of the Utility Model

[0010] Through the provided power component, driving the power component, the power component will drive the rotating bracket to rotate, causing the rotating bracket to first rotate 180° to the left and then 180° to the right, thereby achieving a radial rotation angle of the rotating bracket of ±180°, and the overall rotation is a full circle of 360°. At the same time, the rotation of the rotating bracket will drive the radar movement to rotate, and the rotation of the radar movement will drive the lens antenna to rotate.
