| 摘要 |
The present invention relates to a segmented cylindrical tide staff system [11] for erection at remote areas for dynamic calibration of electronic tide meters and computer models of tides, said tide staff system consisting of plurality of cylindrical tubes [12], said cylindrical tube being coupled to a flange [13] at its end through a circular orthogonal hole [20] drilled on a flat surface of the flange, said flange being provided with plurality of equally spaced slots [15] drilled on the flat surface of the flange, an outwardly protruding tide indicating arm [14] being mounted on the flange wherein said tide indicating arm consists of two mutually orthogonal planes [22] and [23], wherein plane [22] is perpendicular to the axis of the tide staff and plane [23] is parallel to the axis of the tide staff, said perpendicular plane [22] being provided with a mounting terminal [21] and a circular hole [27] and said parallel plane being partitioned into two compartments [24] and [25] by a separating line [26] thereby permitting indication of tide reading in more than one language, including a vernacular language and two or more cylindrical tubes being coupled to each other through slots [15] using coupling means.
