Abstract
The present invention relates to a mechanism capable of minimizing measurement error due to sound speed compensation by inserting a plurality of bar check plates into the sea water so as to be sequentially disposed by a predetermined distance away from the seabed, thereby minimizing wire bending or tilting of the bar check plates. More specifically, a wire; and a bar check plate in which one region is cut inward to allow the wire to enter inwardly; and a detachable part installed on one surface of the bar check plate to detach the bar check plate from the wire; And a coupling means for fixing the detachable part to the bar check plate. Accordingly, it is possible to minimize the error of the sound velocity measurement by keeping the bar check plate horizontal, minimizing the friction with the current and minimizing the wire bending in the sea water. In addition, since the bar check plate and the wire are separated, it is easy to manage, and in particular, the bar check plate can be installed at intervals desired by the user. In addition, the bar check plate and the detachable part may be rotatable to prevent the wires from being shortened and further minimize the error of the sound velocity measurement.
Description
The present invention relates to a bar check mechanism used to measure sound velocity with an echo sounder, and more particularly, a plurality of bar check plates are inserted into sea water so as to be sequentially arranged a predetermined distance away from the seabed, so that the wire is bent or the bar check plate is The present invention relates to a bar check mechanism capable of minimizing inclination and minimizing measurement error due to sound speed compensation.
In general, an echo sounder is used to measure the depth of the seabed, which emits sound waves toward the seabed, and measures the depth of the seabed by measuring the time when the sound waves are reflected back to the seabed. . That is, the depth of the water is measured by applying the formula D = t / 2 * v, which is the average transmission velocity of sound waves (v) after dividing the time (t) by which sound waves emitted from the seabed are reflected back from underwater. Multiplying 1,500m / s gives us the depth to the bottom.
However, since the sound velocity in the seawater, which is the standard of sound echo, changes due to the temperature, salinity, water pressure, etc. of the seawater, the measured value includes an error caused by the difference in sound velocity, and thus is not accurate. Therefore, there are various methods for correcting such errors, such as using a bar check plate, measuring salinity and temperature of seawater, obtaining a revised value, and obtaining a sound speed directly by a sound speed controller. The method is most used because of its high reliability.
The conventional method using a bar check plate is composed of a wire having a weight at the end and a bar check plate of a disc shape. By the way, the bar check plate is not installed on one wire, but the bar check plate is fixedly installed at the end of the wire of a certain length, and a plurality of units having hooks are attached to the bar check plate on the opposite side to which the wire is connected. . Accordingly, the bar check plate is rotated by the current in the sea water, the wire is twisted, the overall length is changed, or the curved portion is bent at the portion connected by the ring and the bar check plate is inclined so that the sound wave does not return. In particular, when measuring the depth of the deep sea floor and low seabed, the spacing of the bar check plate is different, but the conventional bar check plate is coupled to the wire of a certain length, so there is a problem that the bar check plate must be manufactured for each length . In addition, the wire and bar check plate are always stored together to keep the wires tangled.
The present invention has been made in order to solve the above problems, it is easy to store and store, and by using a continuous straight wire while preventing the wire twisted by the current flow, the bar check plate is inclined and the wire bending to minimize the sound speed compensation The purpose is to provide a bar check mechanism that can minimize the measurement error caused by
An object of the present invention, a wire; and a bar check plate in which one region is cut inward to allow the wire to enter the inside; and a detachable part installed on one surface of the bar check plate to detach the bar check plate from the wire. ; And a coupling means for fixing the detachable part to the bar check plate.
The bar check plate may further include a stopper installed on the wire so that the bar check plate is installed at a specific position of the wire.
In addition, the detachable portion may include a coupling piece which is installed to block a cut region of the bar check plate in order to prevent the bar check plate from being separated from the wire.
In addition, the detachable portion is formed so that the center of gravity of the bar check plate is located at the lower part of the bar check plate to prevent the bar check plate from inclining and the bar check plate is rotated by the current to minimize the bending of the wire by the current. It may further include; a guide piece protruding downward in one portion.
As described above, the bar check mechanism according to an exemplary embodiment of the present invention maintains the horizontal level of the bar check plate and minimizes the bending of the wire by the current in the sea using a continuously formed straight wire that does not need a ring connection. There is an effect that can minimize the error of the measurement. In addition, since the bar check plate and the wire are separated, it is easy to manage, and in particular, the bar check plate can be installed at intervals desired by the user. In addition, the bar check plate and the detachable part may be rotatable to prevent the wires from being shortened and further minimize the error of the sound velocity measurement.

In the prior art, the bar check plate is fixed to the wire. Therefore, in order to change the number of bar checkers according to the water depth or to adjust the gap between the bar checkers, additionally, the number of bar checkers may be connected to increase the number of bars, or additional wires of a certain length may be additionally connected between the bar checkers. By adjusting the spacing between the bar check plates. In particular, a ring connection is used as a method of connecting wires. That is, in order to change the number of bar checkers according to the water depth or to adjust the gap between the bar checkers, wires between the bar checkers had to be connected and used. .
