The invention relates to a device for online measurement of the thickness of river channel ice, which includes a support column, a control box, a measuring part and a driving part. There are connecting rods between the supporting columns, and there are measuring parts between the connecting rods. The measuring part includes a slide bar, a buoy Plate, sliding block and measuring cylinder, the measuring cylinder is filled with alcohol, the alcohol contains upper suspension block, lower suspension block, displacement sensor and reflector, the upper suspension block is internally rotated with displacement sensor, and the upper end of the lower suspension block has reflective light plate, the present invention relies on the distance between the floating plate and the sliding block to determine the thickness of the ice layer, the lower end of the displacement sensor is flush with the surface of the ice surface, the upper surface of the reflector is flush with the lower surface of the ice layer, and the distance is measured with the displacement sensor, and The displacement sensor is placed in alcohol, the light or wave used for measurement propagates in the same medium, there will be no change in the speed of light or wave propagation, and the measurement result is accurate.
Description
technical field [0001] The invention relates to the technical field of hydrological detection, in particular to an on-line device for measuring the thickness of river channel ice. Background technique [0002] In northern my country, the temperature is low in winter and freezing phenomena are common. Natural phenomena such as ice formation, disappearance, and accumulation in rivers, lakes, and reservoirs not only seriously affect the operation of many water conservancy facilities and water transportation, but also affect the lives and property of people along the rivers. security damage. [0003] Whether it is environmental resources, hydrological management or hydraulic structure design, it is necessary to understand the relevant indicators of the ice layer, among which the most intuitive, basic and most important indicators are the thickness of the ice layer and its changing process. [0004] Existing detection methods of ice layer thickness include 1. manual measurement b...
