JPH0411596A - Measurement of draft line - Google Patents

Abstract

PURPOSE:To safely measure the draft line without being influenced by waves by inserting a scale wire having a float at the top edge in a telescope type guide type suspended from a broadside and driving-in/out a guide pipe according to the scale wire driving-in/out quantity. CONSTITUTION:A piece of the supporting metalware 2 is rotatably connected with a hinge 2 installed on a hull 1, and a telescope type guide pipe 4 is connected and suspended through a hinge 2a. A scale wire 5 is inserted through the inside of the pipe 4, and a float 7 is installed at the top edge of the wire 5, and the wire 5 is driven-in/out by a winch 8. When the pipe 4 is suspended from a broadside, and the wire 5 is driven out by the winch, the float 7 is separated from a stopper 10, and driven out downward, and then also the guide pipe 4 is lowered and extended, and the lower edge is immersed under the draft line 6. Accordingly, the float 7 is floated up on the draft line 6, and the draft is measured by the scale on the wire 5 without being influenced by waves.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for measuring the water intake of a ship, particularly a ship having a wine cup-shaped hull.

[Prior art] In order to measure the stuttering water of a ship, as shown in Fig. 2,
2 with a water mark 23 and a fixed ladder 24 installed on the side of the ship.
This is done by leaning out from the boat and reading the water mark 23, or by approaching the side of the boat where the water mark 23 is placed on a boat floating on the sea surface and reading the water water mark 23.

[Problems to be Solved by the Invention] However, the conventional method for measuring the stuttering of a ship has the following problems.

(1) Using a ladder: In the case of a vessel with a wine cup-shaped hull, it is impossible to accurately read the water mark, and in order to read the water mark, one must extend one's body far out to sea. It is dangerous, especially near the propeller.

(2) By boat: It takes too much time and effort to measure the water intake.

This invention solves the above-mentioned problems of the prior art,
The purpose of this study is to provide a method for measuring a ship's stuttering that can be carried out safely and easily.

Means for Solving the Problem: The water-strain measuring method according to the present invention uses a telescopic guide pipe that is fixed to the ship's side from the side and suspended in the sea, and a float that is guided inside the guide pipe and floats on the sea surface at the tip. and a winch for feeding out and retracting the scale wire, and the guide pipe is configured to be paid out in accordance with the feeding out of the scale wire and retracted in accordance with the retraction of the scale wire. This is a hoisting measurement method that measures the hoarseness of a ship while letting out a scale wire.

[Function] The hydrostatic measurement method according to the present invention includes: a telescopic guide pipe fixed to the hull from the side and suspended in the sea; a scale wire guided within the guide pipe and having a float floating on the sea surface at the tip; and a winch for feeding out and retracting the scale wire, and the guide pipe is configured to be paid out in response to the payout of the scale wire and retracted in accordance with the retraction of the scale wire, and the guide pipe is configured to be retracted in accordance with the retraction of the scale wire, and the guide pipe is configured to be retracted in accordance with the retraction of the scale wire. We are trying to measure ship power and water intake. And, since the hives can be measured by reading the scale of the scale wire, the hives can be measured safely and easily. In addition, the guide pipe and scale wire can be fed out and retracted by winch operation, so one person can measure hiccups and store the measuring equipment. Furthermore, since the scale wire float is placed inside the guide pipe, it is possible to accurately measure hiccups without being influenced by waves.

[Example] A stuttering measuring method according to an example of the present invention will be explained with reference to FIG. FIG. 1 is a side view showing the installation of the guide pipe, scale, and winch for feeding and retracting used in the stuttering measuring method according to one embodiment of the present invention. A telescopic guide pipe (three stages in the case of Fig. 1) 4 is rotatably attached to a support metal 3 rotatably connected to a hinge 2 fixedly attached to the hull 1 via a hinge 2a. They are connected and suspended so that their ends are submerged in the sea. and,
A scale wire 5 is passed through this guide pipe 4 at sea level 6.
A float 7 floating on the sea surface 6 is attached to the tip of the scale wire 5. Then, the scale wire 5 is fed out and retracted by a winch 8 via a guide roller 9.

When measuring hiccups with the equipment arrangement as described above, a reduced telescopic guide pipe 4 is suspended from the hull 1. At this time, the lowest pipe 4 of the guide pipe 4
The float 7 hits the expansion/contraction stopper 10 of a, and the guide pipe 4 is pulled up by the scale wire 5 while being reduced. When the scale wire 5 is let out by the winch 8 from this state, the float 7 goes down and at the same time the lower end of the guide pipe 4 also goes down, so the guide pipe 4 expands as the scale wire 5 is let out. , finally as shown in Figure 1,
The lower end of the guide pipe 4 sinks into the sea, and the float 7 at the tip of the scale wire 5 floats on the sea surface.

Then, by reading the scale on the scale wire 5 that points to a predetermined reference point on the ship at this time, the hiccups can be measured.

When the measurement of stuttering is completed, the scale wire 5 is retracted by the winch 8. Then, the float 7 leaves the sea surface 6 and hits the expansion/contraction stopper 10 of the guide pipe 4, so that the guide pipe 4 is reduced in accordance with the retraction of the scale wire 5. After the guide pipe is completely reduced, it is rotated at the hinge 2a and pulled onto the ship.

Further, the support hardware 3 and the guide pipe 4 are simultaneously rotated at the hinge 2 and stored in a vertically erected state.

The method for measuring hiccups according to one embodiment of the present invention is carried out in the manner described above, so that hiccups can be measured safely and easily. In addition, the guide pipe and scale wire can be fed out and retracted by winch operation, so one person can measure hiccups and store the measuring equipment. Furthermore, since the scale wire float is placed inside the guide pipe, it is possible to accurately measure hiccups without being influenced by waves.

[Effects of the Invention] According to the present invention, the water level of a ship can be safely and easily measured by one person, and can be measured accurately.
