| Zusammenfassung: | The present invention relates to a staff for water depth measurement, which is for measuring the water depth of rivers, etc., and more specifically, to a staff for water depth measurement, comprising: a ruler body having a predetermined width, thickness and length and scales formed on the outer surface and a flange part positioned at the lower end of the ruler body; and a water level indicator capable of moving up and down along the outer surface of the ruler body, wherein the water level indicator has a specific gravity smaller than that of water so as to move up and down according to the water level. The staff for water depth measurement according to the present invention can accurately measure a water depth even when the water surface fluctuates.
본 발명은 하천 등의 수심을 측정하기 위한 수심 측정용 스타프에 관한 것으로, 보다 상세하게는 소정의 폭, 두께 및 길이를 가지며 외측 표면에는 눈금이 형성되어 있는 막대자 몸체 및 상기 막대자 몸체 하측 단부에 위치하는 플랜지부를 포함하는 막대자; 및 상기 막대자 몸체 외측면을 따라 상하로 이동 가능한 수위 표시부를 포함하되, 상기 수위 표시부는 수위에 따라 상하로 이동할 수 있도록 물보다 비중이 작은 것을 특징으로 하는 수심 측정용 스타프에 관한 것이다. |
