Description

  The present invention relates to a freeboard measuring apparatus for measuring freezing of a floating body used for a floating pier or the like.

  For floating bodies floating on the water such as floating piers, etc., the floating body of the floating body, that is, the part that floated on the water, such as level adjustment when bridging the bridge between the floating bodies or between the floating body and the shore It may be necessary to manage the height of the.

  In that case, conventionally, a measuring instrument with a scale such as a staff or convex is sent along the side of a floating body such as a floating pier, and the operator reads it visually from a ship or the like that lays the scale on the floating body. The dredging or draft was measured (for example, refer patent document 1).

  In addition, the height management of ships and floating bodies is often managed based on drafts, and various devices for measuring drafts have been developed. In some cases, dry droughts are also calculated based on drafts.

And a laser distance meter 6 fixed to the upper end portion of the measurement cylinder 4.

  The measuring cylinder 4 is formed in a tubular shape having upper and lower ends that are substantially the same as the height of the floating body 1, and its upper end is attached to the upper surface of the floating body 1 via the attachment member 7. While being fixed up and down along the side, the lower end is inserted in water.

  This measuring cylinder 4 is constituted by short pipe members 8, 8... Made of a plurality of vinyl chloride pipes, and the short pipe members 8, 8... Are connected via a joint 8a.

  Further, the short tube member 8 connected to the lowermost end is not particularly shown, but includes, for example, an escape prevention means including an escape prevention flange or the like projecting inwardly at the lower end opening, and the measuring cylinder 4 It is preferable to prevent the reflecting floating member 5 inserted inside from coming out of the lower end opening.

  Further, the short tube member 8 disposed at the uppermost end is integrally formed with a flange-like support projecting portion 8c projecting outward at the upper end portion.

  The mounting member 7 is formed in a rectangular flat plate shape with a steel plate or the like, and the other end side is fixed to the upper surface portion of the floating body 1 so that one end side in the longitudinal direction protrudes outward from the side surface of the floating body 1. The fixing means for the mounting member 7 to the floating body 1 is not particularly limited, but is firmly fixed by welding, bolting or the like.

  In addition, the mounting member 7 has an insertion hole 7a through which the upper end portion of the measuring cylinder 4 is fitted in the end portion protruding from the side surface of the floating body 1 in the longitudinal direction. The short tube member 8 disposed at the uppermost end is fitted into the insertion hole 7a, and the lower surface of the support overhanging portion 8c is supported by the edge of the insertion hole 7a, so that the measurement cylinder 4 is directed upward and downward.
