Device and method for automatic detection of ice thickness

Abstract

The invention discloses a device and method for automatic detection of ice layer thickness. The device includes a fixed bracket. The fixed bracket includes a beam. A bracket through hole is arranged on the beam. An alloy conduit passes through the bracket through hole. In the wave-transparent sealing cover, a measuring component is arranged in the wave-transmitting sealing cover; a detection line and an electromagnet are arranged inside the alloy conduit, and one end of the detection line is connected to the measuring component, and the other end is connected to the electromagnet. The lower end of the fixed alloy conduit is connected with a fixed tray, the iron ring is set on the outside of the alloy conduit, and the stroke reset switch is arranged on the fixed tray and inside the alloy conduit. The device of the present invention realizes real-time monitoring of ice thickness and remote transmission of data when ice conditions occur, and real-time monitoring of water level and remote data reporting during ice-free periods.

Description

technical field [0001] The invention relates to the technical field of wireless intelligent measurement, in particular to an automatic ice thickness detection device and method. Background technique: [0002] The monitoring of ice thickness and its change is an important means of analyzing ice conditions and ice push (pressure) force in cold regions, and is of great significance to the safe operation of water projects. At present, the main monitoring methods are borehole measurement, electrical measurement, ultrasonic and ground penetrating radar. The drilling method obtains cylindrical ice samples for measurement, but it requires high technical requirements for drilling equipment transportation and manual operation; the electrical measurement method uses the weak conductivity of water and ice, the electrical insulation properties of air, and the capacitance of air, ice and water The difference in characteristics automatically detects the thickness of the ice layer, but the...

Problems solved by technology

The drilling method obtains cylindrical ice samples for measurement, but it requires high technical requirements for drilling equipment transportation and manual operation; the electrical measurement method uses the weak conductivity of water and ice, the electrical insulation properties of air, and the capacitance of air, ice and water The difference in characteristics automatically detects the thickness of the ice layer, but the monitoring accuracy in specific applications will be affected by the environment such as temperature, and the measurement is not intuitive enough, and it is impossible to monitor the water level of reservoirs, rivers, channels, etc. in summer and other periods when there is no ice

The specific measurement accuracy of ultrasonic and ground penetrating radar measurement methods needs to be improved
