The utility model discloses an integrated solar
radiation three-element
measuring instrument, which comprises a lower shell, a circular upper cover is fixed at the upper end of the lower shell, and a hemispherical light-transmitting cover is buckled on the top surface of the upper cover; the top surface of the upper cover is provided with a plurality of rows of mounting holes and
light guide columns; an arc-shaped shading ring is fixed on the top surface of the upper cover; an included angle is formed between the shading ring and the top surface of the upper cover; the shading ring spans above the plurality of rows of mounting holes; a
signal acquisition plate is fixed at the top in the upper cover, a plurality of rows of photoelectric sensors are arranged on the
signal acquisition plate, and the photoelectric sensors are in one-to-one correspondence with the
light guide columns; and a measurement mainboard is arranged in the lower shell and is used for receiving signals of the
photoelectric sensor. The
measuring instrument is high in integration level, small in size, small in installation space, convenient to carry and reliable in work; synchronous measurement of total solar
radiation, horizontal scattered
radiation and horizontal
direct radiation is realized, a mechanical moving part or an external solar tracking device is not needed, the problems of
mechanical wear, clamping stagnation and the like are avoided, and the working reliability is remarkably improved.
