Ice layer thickness automatic detection device and method

Abstract

The invention discloses an ice layer thickness automatic detection device and method. The device comprises a fixed support, wherein the fixed support comprises a crossbeam, the crossbeam is provided with a support through hole, an alloy guide tube penetrates the support through hole, a wave transmitting sealing cover is fixedly arranged at the top of the alloy guide tube, a measurement component is arranged in the wave transmitting sealing cover, a detection wire and an electromagnet are arranged inside the alloy guide tube, one end of the detection wire is connected to the measurement component, and the other end of the detection wire is connected to the electromagnet; the fixed lower end of the alloy guide tube is connected with a fixed support plate, an iron ring is sleeved outside thealloy guide tube, and a stroke reset switch is arranged on the fixed support tray and is inside the alloy guide tube. When water freezes, the device can monitor ice thickness in real time and transmitdata in long distance; when in ice-free period, the device can monitor water level in real time and report data remotely.

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
