The invention discloses a radar level gauge device and method for complex working conditions, and belongs to the technical field of radar measurement. In the invention, a jacking mechanism is arranged in a casing, and the jacking mechanism drives a connecting pipe to ascend and descend in a fixed pipe. The gas channel on one side of the connecting pipe and the fixed hole on the fixed pipe can be connected and separated, and the gas and liquid are respectively introduced into the fixed hole to isolate the volatile attachments on the inner wall of the antenna and clean the inner wall of the antenna. Function, in the working state, by passing air, the gas forms a gas isolation film at the bottom of the antenna, so as to avoid the adherents from adhering to the inner wall of the antenna, which affects the measurement accuracy of the radar level gauge. into the liquid to realize the cleaning of the inner wall of the antenna, and to avoid the abnormal positioning of the radar level gauge caused by repeated disassembly of the radar level gauge; the present invention is used to solve the technical problem that impurities, steam and adhesions cannot be isolated in the existing solution. .
Description
technical field [0001] The present invention relates to the technical field of radar measurement, and more particularly, to a radar level gauge device and method for complex working conditions. Background technique [0002] The radar level meter adopts the measurement method of microwave pulse, and can be normal in the industrial frequency band with low beam energy. Non-contact continuous measurement; suitable for occasions with large changes in dust, temperature and pressure, and the presence of inert gas and steam. [0003] The utility model patent with the application number of 2019219147631 discloses a radar level meter. The patent completes the cleaning of the antenna through a cleaning component arranged on the flange. The user can clean it without disassembly during use, and improve the performance of the antenna. It improves the work efficiency and reduces the difficulty of clearing, thus providing convenience to users and improving the accuracy of radar level gauge...
