The invention proposes an organic reversible temperature-sensing material-based temperature measurement device. The organic reversible temperature-sensing material-based temperature measurement devicecomprises a heat conduction unit and a temperature-sensing color-changing unit, wherein the heat conduction unit is used for transferring heat emitted from a hot source and changing a temperature with temperature change of the hot source, the temperature-sensing color-changing unit is attached onto the heat conduction unit and is used for changing color with the temperature change of the heat conduction unit, the organic reversible temperature-sensing material-based temperature measurement device also comprises a transparent heat-insulation unit, the transparent heat-insulation unit wraps theheat conduction unit and the temperature-sensing color-changing unit, a heat transfer end part of the heat conduction unit is exposed out of the transparent heat-insulation unit, and the color changing condition of the temperature-sensing color-changing unit can be shown from the transparent heat-insulation unit. The temperature measurement device is implemented on the basis of an organic reversible temperature-sensing material, the temperature of the hot source is shown at a corresponding graduation position on the temperature measurement device according to a basis principle of engineeringheat transfer, an operator can conveniently obtain a reference value of a pre-heating temperature by color changing of the temperature-sensing material, and a convenient and accurate idea is providedfor temperature detection of thermal treatment before welding.
Description
technical field [0001] The invention relates to a temperature detection instrument, in particular to a temperature measurement device based on an organic reversible temperature-sensing material. Background technique [0002] With the concept of sustainable development gradually gaining popularity, offshore wind power has been paid more and more attention as a green production capacity equipment. However, since most offshore welding structures are welded with large thick plates and require high-altitude operations, preheating before welding is required in order to reduce welding defects. Welders often use flame preheating, and the preheating temperature depends only on the worker's operating experience. Traditional contact thermistor temperature measurement (except for special high temperature thermistors, most thermistors are only suitable for 0 ~ 150 ℃) and thermocouple temperature measurement methods (0 ~ 1800 ℃) need to destroy the surface of the heat source to RTDs or t...
