Radiation measuring device of light-gathering heat collection pipe and scanning analysis method thereof

The invention belongs to the field of solar heat collection, in particular relates to a radiation measuring device of light-gathering heat collection pipe and a scanning analysis method thereof. The radiation measuring device of light-gathering heat collection pipe comprises a heat collection pipe sleeve, an axial scanning driver, wherein a circumferential scanner and a spectral radiometer, the device is fixed on the heat collection pipe to be measured to form a heat collection pipe assembly, the heat collection pipe assembly is arranged on the focal line of a parabolic groove face reflector, the axial scanning driver realizes the axial movement of the circumferential scanner, the circumferential scanner realizes the circumferential scanning movement of optical fiber, and the optical fiber transmits the received radiation energy to the spectral radiometer, so that fine measurement of radiation energy flow at the surface of the heat collection pope is realized; the scanning analysis method uses optical fiber to collect and transmit the focus radiation energy at the wall surface of the heat collection pipe point by point, uses the spectral radiometer to measure the optical parameters, and optically detects the parameters of the radiation energy flow at the wall surface of the heat collection pipe including light intensity, optical power spectral density, color temperature, and the like. The invention is applied to solar thermal power generation requiring high power condensation.
