Sun angle measuring instrument

The utility model relates to the technical field of measuring devices, in particular to a solar angle measuring instrument which comprises a measuring scale and a bottom plate in an isosceles right triangle shape, an installation portion is arranged in the middle of the bevel edge of the bottom plate, and a vertical insertion rod is installed on the installation portion. The bottom plate is provided with a semi-circular arc-shaped groove by taking the middle part of the bevel edge of the bottom plate as an original point, and protractor scales are arranged along the edge of the semi-circular arc-shaped groove; one end of the measuring scale abuts against the installation part, and the measuring scale is provided with measuring scales. The solar azimuth angle measuring device is novel in structure, the horizontal plane is selected on the ground, the inclined edge of the bottom plate is horizontally placed in the east-west direction, and the solar azimuth angle can be directly measured through the protractor sc
