Measurement device of zenith angle

A measuring device of zenith angle, comprising:

• a light receiving member (1), comprising solar panels (11), a support frame (12), and a first counterweight member (13), wherein the support frame (12) is of a regular pyramid structure, a corresponding position of each inclined plane of the support frame (12) is covered with the same solar panel (11), the first counterweight member (13) is connected to the support frame (12), and a mass of the first counterweight member (13) matches that of the solar panels (11) and the support frame (12);
• light intensity processing circuits (2) electrically connected to the solar panels (11) and configured to determine a rotating angle of the support frame (12) based on intensity of light received by each solar panel (11);
• a direction adjusting member (3) electrically connected to the light intensity processing circuits (2) to adjust angles of the support frame (12) in a vertical direction and a horizontal direction, wherein the angle of the support frame (12) in the vertical direction is a zenith angle;
• and
• a stability maintaining base (4), comprising a bracket (41), a first fixing member (42), and a second fixing member (43), wherein the first fixing member (42) is rotatably connected to the bracket (41), the second fixing member (43) is rotatably connected to the first fixing member (42), and the direction adjusting member (3) is rotatably connected to the second fixing member (43).
