An anti-freezing probe for polar optical measurement in the North and South poles

Abstract

The invention discloses an anti-freezing probe for optical measurement in the south and north polar regions. The probe comprises a probe body, a cosine light concentrator which has a half-spherical front part and is provided with a groove in the back part, a fixing element, a heating wire, a temperature sensor, a first dry layer, a heat-conducting buffer layer, and an optical fiber. The first dry layer covers the bottom of the groove, and the heat-conducting buffer layer is arranged on the four wall surfaces of the groove. The optical fiber includes an optical fiber tube and an optical fiber connector, the optical fiber connector extends into the probe body from the fixing element at the back end of the probe body and abuts on the first dry layer, and the other end of the optical fiber tube is connected with an information collection device. The heating wire is clamped between the optical fiber connector and the heat-conducting buffer layer. The temperature sensor is connected with a temperature switch connected with the heating wire, and a control center used for receiving temperature information and controlling the temperature switch to realize on-off. The problem that optical measurement error is caused or optical measurement cannot be carried out when an optical probe window is frozen due to freeze is solved, and the probe is prevented from damage due to internal overheating.

Description

technical field [0001] The invention relates to the field of polar or low-temperature environment monitoring, in particular to an anti-freezing probe for optical measurement of polar regions. Background technique [0002] The earth's north and south poles have a major impact on the global climate and ecological environment, so it is necessary to study the energy budget and the distribution of sunlight in polar regions or frozen environment regions. [0003] Due to the harsh low temperature environment in the Arctic and Antarctic regions, the generation of ice and snow will cause the freezing of the optical measurement window, and the ice attached to the probe will affect the accuracy of optical measurement, and even lead to the failure of the probe measurement in severe cases. Especially for the situation where the probe is set vertically downward to measure the upward radiation flux, due to the influence of gravity during the melting and recondensation of ice and snow on th...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no probe specially used for long-term luminous flux measurement in the polar freezing environment in the world. For the problem of ice and snow freezing and blocking the probe due to gravity, there is no perfect solution for the time being.
