AI Technical Summary

Technical Problem

Existing radar flow meters cannot adjust the detection direction in real time according to the direction of water flow, resulting in inaccurate detection data and the risk of false alarms and missed alarms. This poses a threat to the safety of railway bridges, especially in the event of emergencies such as floods.

Method used

A device was designed that includes a pole, a crossarm, an electronically controlled gimbal, a radar flow meter, a water flow direction detection device, and a solar panel. The device automatically adjusts the direction of the radar flow meter to match the water flow direction through an electronically controlled module and a water flow direction detection device. The electronically controlled gimbal and a rotary motor are used to achieve real-time steering of the radar flow meter.

Benefits of technology

This ensures that the radar flowmeter's detection results are parallel to the water flow direction, improving the accuracy and reliability of detection, reducing the possibility of false alarms and missed alarms, and enhancing the safety and accuracy of hydrological monitoring of railway bridges.

Abstract

The utility model relates to the technical field of railway bridge hydrological monitoring, and particularly discloses a radar water level measuring device capable of steering automatically. Comprising a vertical rod, a cross arm, an electric control holder, a radar flowmeter, a water flow direction detection device, a solar panel and an electric control module, the solar panel is installed on the top of the vertical rod, the cross arm is fixedly installed on one side of the vertical rod, the electric control holder is fixedly installed at the free end of the cross arm, the radar flowmeter is installed on the electric control holder, and the water flow direction detection device is fixedly installed at the position, below the radar flowmeter, of the vertical rod. The electric control module is electrically connected with the electric control holder, the radar flowmeter and an angle sensor of the water flow direction detection device. The solar panel is electrically connected with the electric control module. By arranging the electric control holder, the direction of the radar flowmeter can be adjusted according to the real-time water flow direction detected by the water flow direction detection device, so that the detection direction of the radar flowmeter is parallel to the water flow direction, and the accuracy and reliability of the detection result of the radar flowmeter are ensured.
