Embodiment Construction

[0012] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0013] see figure 1 , The tidal flat elevation measuring instrument of the present invention is provided with telescopic rod 1, level bar 2 and laser pen 3, and level bar 2 is arranged on the top of telescopic bar 1 horizontally, and laser pen 3 is located at the top of level bar 2. The spirit level 2 is used to ensure the level of the measurement line of sight, the laser pointer 3 can track the elevation reference point A, and the telescopic rod 1 can adjust the height difference.

[0014] When measuring, first do the indoor preparations before the measurement, check the highest tide time and the highest tide level announced by the marine hydrological information department, and record the highest tide level and time on the day of the survey. There is no need to find an "elevation datum point" near the research site as a reference point. Moreover, ...

Abstract

The mudflat height measuring instrument and its measuring method relates to a highness measuring device, especially to a simple measuring instrument for the height measuring and its measuring method. The mudflat height measuring instrument includes the flex pole, level ruler and laser pen, wherein the level ruler is arranged on the top of the flex pole horizontally, and the laser pen is arranged on the level ruler. Consulting and recording the tiptop wave location and time of today released by the sea hydrology information department before measuring; marking the tiptop wave location as the height referring point when the waiting measured sample is on the corresponding climax, after the wave ebbing and the mudflat showing, setting up the measuring instrument on the waiting measuring sample location; telescoping the height of the pole by adjusting the measuring instrument to make the level pole keeping level orientation, and the light point of the laser pen records the height of the flex pole according to the climax point of the nearest quay red oil paint marker, then the mudflat height can be firmed by computing the errand between the height of the flex pole and the plumb height of the actual climax line.

Description

technical field [0001] The invention relates to a height measuring device, in particular to a simple measuring instrument mainly used for tidal flat height measurement and a measuring method thereof. technical background [0002] In marine scientific research, the elevation of tidal flats is an important habitat parameter. In order to obtain this parameter, horizontal surveying, triangulation elevation measurement and other physical elevation measurements (such as hydrostatic leveling, barometric elevation measurement) can be used. Even the method of GPS measurement. However, the most commonly used method is the leveling method. This method uses the horizontal line of sight provided by the level to observe the leveling staff erected on two points, and read the readings on the staff to calculate the height difference between the two points. By comparing the research site with the known elevation reference point, the elevation of the research site can be deduced (1, Mayingnua...
