The utility model provides a measurement principle of device as follows:
as shown in fig. 7, the center of the earth is O, the axis of the cylinder is a point P when viewed from the side, then OP is approximately the direction of gravity, and the angle between OP and the sun ray is the solar altitude, denoted as θ, as shown. Note that OP intersects with the arc line on the side of the cylindrical structure at point H, then a scale is placed on the inner side of the cylindrical structure, and if H (the line where it is) is taken as the zero scale line, when the sun light is perpendicular to the axis of the cylindrical structure, the "reading" of the shadow line of the projection of P (thin line) on the thin line on the inner side of the cylindrical structure on the scale is the degree θ of the sun's altitude. Therefore, here is required: the zero scale line (H) is on OP (plane), and the zero scale line (H) is vertical to the gravity line, and the sun ray is vertical to the cylindrical axis.
As shown in fig. 8, the center of gravity of the cylindrical structure (including the pulley) is a, and the contact point of the pulley and the guide rail is B. The guide rail can rotate by taking the I as a rotating shaft, and the B is a stress point of the guide rail; the shell of the pulley can rotate by taking m as a rotating shaft, and A is a stress point; meanwhile, the cylinder device can rotate left and right by taking the tangent line n of the B as an axis and the A as a stress point. The moment of the stress point corresponding to each rotating shaft is zero when the device is stable, namely a straight line is made through the point A in the gravity direction and is marked as i, and the straight line i is intersected with m and n. This is achieved when the centre of gravity a is on a line directly below the pulley. This explains why it is necessary to ensure that the centre of gravity of the cylindrical structure (including the pulley) is directly below the pulley.
As shown in fig. 9, assume that the a-line satisfies the following condition: when the cylinder axis is in the horizontal direction and the solar ray is perpendicular to the cylinder axis, the line a is parallel to the gravity line, and the relative positions of the line a and the cylinder structure are never changed (i.e., the line a is always stationary with the cylinder structure as a reference frame). From the geometric relationship, the angle θ between the projection of line A and the thin line is the reading of the instrument. When the cylinder axis is horizontal, the reading theta is the degree of the solar altitude. And the reading theta is the included angle between the solar ray and the line A according to the geometrical relation. Therefore, when sunlight is perpendicular to the cylindrical axis, if the cylindrical axis is not horizontal, the direction of the line A changes, the included angle theta between the line A and the sunlight may change, and theta is the reading of the instrument, which means that the reading is not necessarily the solar altitude. The cylinder axis must remain horizontal. Thereby illustrating the reason why the cylindrical axis of the device must be kept horizontal.
It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
