AI Technical Summary

Technical Problem

When the radar level gauge is used in a storage tank, echo attenuation or signal loss due to the pile of materials, and dust or floating objects on the surface of the antenna affect the use.

Method used

A radar antenna device is designed, including a blowing mechanism and a purge mechanism, which purifies the antenna surface through air flow, removes dust, and limits and adjusts the angle of the radar device through a restriction mechanism, a brake mechanism and an auxiliary mechanism to improve the practicality of the device.

Benefits of technology

It effectively avoids excessive dust affecting the normal use of the radar level gauge, improves the stability and accuracy of the signal, and improves the working smoothness of the universal joint through the addition of lubricating oil.

Abstract

The invention relates to the technical field of radar level meters, and discloses a radar antenna device and a radar level meter, comprising a radar device body; in the daily work of the radar device body, a first universal joint and a transmitter antenna of the level meter, when the radar device body brings the transmitter antenna of the level meter to change its angle, the purge mechanism can generate air flow under the action of the purge mechanism, thereby purge dust on the surface of the transmitter antenna of the level meter, thereby avoiding excessive dust on the surface of the transmitter antenna of the level meter and affecting the normal use of the transmitter antenna of the level meter; in addition, under the action of a limiting mechanism, a braking mechanism and an auxiliary mechanism, the angle of the radar device body and the first driving plate can be limited, thereby improving the practicability of the device, and when the auxiliary mechanism is working, the driving mechanism and the oil supply mechanism can be operated, thereby adding lubricating oil to the surface of the first universal joint.
