Monitoring device for inclining, sinking and horizontal displacement of four-antennae electric transmission line tower frame

Abstract

The invention relates to the field of electric power transmission engineering, can monitor inclining, sinking and horizontal displacement of electric transmission line tower frames in unfavorable geological areas and solves the technical problems that current inclining detecting devices of the electric transmission line tower frames can not really measure inclined angles of the tower frames and can not measure sinking and horizontal displacement values of the tower frames. A monitoring device for inclining, sinking and horizontal displacement of a four-antennae electric transmission line tower frame comprises a base station and a mobile station, the mobile station comprises a first global navigation satellite system (GNSS) satellite receiving plate, a second GNSS satellite receiving plate, a second data transmission broadcasting station and a mobile station management circuit, the first GNSS satellite receiving plate and the second GNSS satellite receiving plate are installed on the electric transmission line tower frame, the second data transmission broadcasting station is connected with signal output ends of the two GNSS satellite receiving plates, the mobile station management circuit is connected with a second global system for mobile communications (GSM) device, and signal input ends of the two GNSS satellite receiving plates are connected with mobile station positioning antennae and mobile station direction-finder antennae which are installed on the electric transmission line tower frame. According to the monitoring device for inclining, sinking and horizontal displacement of the four-antennae electric transmission line tower frame, differential settlement of a tower frame base and foot distance changes of the tower frame can be measured, and the measuring accuracy is increased.

Description

technical field [0001] The invention relates to the field of electric power transmission engineering, which can monitor the inclination, sinking and horizontal displacement of transmission line towers located in unfavorable geological areas. Background technique [0002] EHV and UHV transmission lines are large channels for electric energy transmission, and their safe operation is crucial to national security, national economic operation and social stability. In the survey and design stage of the transmission line, the design department will carefully select the route of the line and the location of the tower, but due to various natural reasons, human factors and economic and technical conditions, some transmission line towers will inevitably be located in areas with poor geology . Transmission line towers located in gobs of coal mines have sunk several meters, moved several meters horizontally, and tilted several degrees, all of which have happened many times in geological...
