The invention relates to a device for online measurement of riverway ice layer thickness, wherein the device comprises supporting columns, a control box, a measuring part and a driving part; connecting rods are arranged between the supporting columns, the measuring part is arranged between the connecting rods, the measuring part comprises a sliding rod, a floating plate, a sliding block and a measuring cylinder, the measuring cylinder is filled with ethyl alcohol, and an upper suspension block, a lower suspension block, a displacement sensor and a reflector are arranged in the ethyl alcohol. The upper suspension block is internally rotatingly provided with a displacement sensor, and the upper suspension block is provided with the reflector. The thickness of an ice layer is determined according to the distance between the floating plate and the sliding block, the lower end of the displacement sensor is flush with the upper surface of an ice surface, the upper surface of the reflector isflush with the lower surface of the ice layer, the displacement sensor is used for measuring the distance, and the displacement sensor is arranged in ethyl alcohol. Light or waves for measurement arepropagated in the same medium, the situation that the propagation speed of the light or the waves is changed is avoided, 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...
