Problems solved by technology
The traditional method of measuring seawater icing mainly obtains sea surface infrared data through satellite remote sensing to calculate the thickness of sea ice. This method needs to be completed by major national projects, which is costly and difficult to obtain instant and effective data. Moreover, satellites are easily affected by the sky. The interference of clouds will reduce the accuracy of data

Abstract
The invention provides an optical fiber probe and a device for measuring sea ice thickness. The optical fiber probe includes a tube body and an optical fiber group, and the optical fiber group is arranged in the inner cavity of the tube body; the optical fiber group includes a main optical fiber and a preset number of sub-fibers, each of which The input ends of the sub-optical fibers are all spliced with the main optical fiber. The main optical fiber and each sub-optical fiber are provided with winding parts. All the winding parts are arranged in sequence along the axis direction of the pipe body with a preset spacing. The device uses the fiber probe . The optical fiber probe applying the invention has the advantages of simple structure, low price and strong timeliness.
Description
technical field [0001] The invention relates to the technical field of optical fiber probes for measuring sea ice thickness, in particular to an optical fiber probe for measuring sea ice thickness, and also to a device for measuring sea ice thickness using the optical fiber probe. Background technique [0002] Sea water freezing has always been an important problem affecting the work and life of fishermen and seafarers. The freezing of sea water makes it impossible for fish to float to the surface to breathe, resulting in reduced fishery production and loss of fishermen. Seawater icing also threatens the safety of seafarers operating at sea. Therefore, collecting seawater icing data and obtaining information on seawater icing conditions has become a very important task for fishermen and seafarers to go to sea in winter. The traditional method of measuring seawater icing mainly obtains sea surface infrared data through satellite remote sensing, and calculates the thickness o...
