TH7618A3 - Solar degree plate - Google Patents

Abstract

DC60 (18/07/55) The environment currently has a lot of interference with the measurement of the magnetic compass. Which makes direction measurement with a needle The magnetic direction is likely to be erroneous with interference by the unaware of the measurement. Solar direction measurement is another option to ensure direction measurement that will not be disturbed by the environment. But there are still disadvantages due to dependence Sunlight, which is present only during the day and can be disturbed by cloudy weather. Solar degree plate The previous invention also had the disadvantage of the clarity of the shadow edges cast on the degree plate, the large axis of shadows, and the near-noon period problems where the shadow may not reach the angle of the invention of the measuring disc. This new type of solar degree to solve such disadvantages. Today, there are many conditions in the environment that interfere with the measurement of the magnetic compass. Which makes direction measurement with a needle The magnetic direction is likely to be erroneous with interference by the unaware of the measurement. Solar direction measurement is another option to ensure direction measurement that will not be disturbed by the environment. But there are still disadvantages due to dependence Sunlight, which is present only during the day and can be disturbed by cloudy weather. Solar degree plate The previous invention also had the disadvantage of the clarity of the shadow edges cast on the degree plate, the large axis of shadows, and the near-noon period problems where the shadow may not reach the angle of the invention of the measuring disc. This new type of solar degree to solve such disadvantages.

1. The sun's degree plate consists of a degree plate (1.1), which is embedded with a wear-resistant bushing (1.3), at the center of the plate from the degree (1.1), with a index arm (1.4) worn on the wear-resistant bushing (1.3), which can be rotated. Around the plate degree (1.1) and there is a circular water level. (1.2) embedded on the degree plate (1.1) for viewing to adjust the level of the degree plate (1.1) with a special characteristic is the pointing arm (1.4), which the bottom has a rotating axis protruding perpendicular to the arm The degree pointer (1.4) can be fitted with the wear bushing (1.3) located in the center bore of the angle plate (1.1), the angle pointer (1.4) can be rotated around the degree plate (1.1) by means of the handwheel. 2. Solar Degree Dish According to claim 1, where the degree plate (1.1) is a three circle line overlapping with a common center By dividing the inner garden between the outer circle and the middle circle And the middle band and the inner circle Into equal parts, all 360 channels, 1 degree per channel by the degree box The outer and inner parts are overlapped by 0.5 degrees, with the number of degrees on the outside of the outer circle every 10 degrees, with the degree sheets (1.1) at the 0, 90, 180, and 270 degree positions centered on all four sides.
