Description

Bar-check equipment

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.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the bar check mechanism 1 according to the embodiment of the present invention includes a wire 10, a bar check plate 20, a detachable part 30, and a coupling means 40. do.

The wire 10 may be a long string continuously formed to reach the sea floor, and may be made of glass fiber or stainless steel having high rigidity without corrosion to seawater. Here, the weight (11) is installed at the end of the wire 10 so that the wire 10 enters vertically well when entering the sea water.

On the other hand, a scale is displayed on the wire 10 so as to know the length of the wire 10 dropped below the surface of the water. In addition, the stopper 12 is fixed to the wire 10 at a predetermined interval so that the bar check plate 20 can be installed at regular intervals. That is, the bar check plate 20 and the detachable part 30 prevent the bar from moving up or down on the wire 10 and are arranged at regular intervals so that the two stoppers 12 are paired with the bar check. Installed in the wire 10 to restrain the plate 20, each pair of stoppers 12 are arranged and fixed at intervals of one meter. This is usually set to the interval of the bar check plate 20 to 2 meters to 5 meters according to the depth of the sea, when the stopper 12 is installed at a distance of 1 meter to the wire 10 bar check plate at various intervals This is because the versatility can be widened because the number 20 can be provided.

Here, the distance between the pair of stoppers 12 is the distance of the height of the height of the bar check plate 20 and the height of the detachable part 30 in the state in which the bar check plate 20 and the detachable part 30 are combined. Placed and fixed to the wire 10 by a distance. A description thereof will be described later.

Bar check plate 20 is a substantially disk-shaped, the insertion groove 21 is cut from one side to the center is formed so that the wire 10 is inserted, bar check plate 20 to be coupled to the removable portion 30 A plurality of through holes 22 are formed at regular intervals in the vicinity of the. Accordingly, the wire 10 is inserted into and coupled to the insertion groove 21 of the bar check plate 20. Here, the bar check plate 20 may be formed of a metal, but may be formed of a metal material such as stainless so as not to be corroded by sea water.

The detachable part 30 has a shape in which a semi-circular plate is semi-bended at right angles, and includes a horizontal coupling piece 31 and a vertical guide piece 32.

The engagement piece 31 is closely coupled to the bottom surface of the bar check plate 20 so as to prevent the bar check plate 20 from being separated from the wire 10, and the bar check plate is coupled to one surface of the engagement piece 31. Coupling holes 33 corresponding to the through holes 22 of 20 are formed.

The guide piece 32 is bent perpendicularly to the end of the coupling piece 31 so as to minimize the inclination of the bar check plate 20 and the bending of the wire 10 due to the current, so as to form a wing. Guide grooves 34 in which the wire 10 is inserted are formed at the inner side ends of the 32.

In the detachable part 30, four detachable parts 30 are installed on the bottom surface of the bar check plate 20, wherein the engaging pieces 31 of the detachable part 30 are the insertion grooves of the bar check plate 20. In order to prevent the bar check plate 20 from deviating from the wire 10 by blocking the 21, the center of the arc circumference of the engaging piece 31 is disposed in the insertion groove 21 of the bar check plate 20. Is installed. This prevents the bar check plate 20 from escaping from the wire 10.

In addition, each guide groove 34 formed in each guide piece 32, that is, four guide grooves 34 are formed to form a cylindrical hole surrounding the wire 10. This is for the guide groove 34 of the guide piece 32 to wrap the wire 10 so that the bar check plate 20 can be kept horizontal. Accordingly, it is possible to minimize the error of the sound velocity measurement by minimizing the inclination of the bar check plate 20. That is, when the bar check plate 20 is inclined, the reflected wave is not properly received from the bar check plate 20, or the sound velocity measurement value is inaccurate by receiving an incorrect reflected wave, thereby minimizing the tilt of the bar check plate 20. It is very important to let them.

In addition, the four detachable parts 30 rotate with the bar check plate 20 around the wire 10 as the current flows through the guide piece 32, which is the current flowing through the bar check plate 20. By reducing the resistance of the wire and minimize the bending of the wire 10 in the sea water, and by preventing the wire 10 is shortened by twisting, it is possible to minimize the error of the sound velocity measurement.

On the other hand, the removable portion 30 has been described that the radius of the coupling piece 31 and the guide piece 32 is formed to be the same as the radius of the bar check plate 20, but smaller than the radius of the bar check plate 20 It may be formed. In addition, the detachable portion 30 is manufactured by forming a shape corresponding to a quarter of a circle, but sometimes forming a shape corresponding to 1/2 or 1/3 of a circle to combine two or three Can also be used. In addition, the detachable portion 30 may be a synthetic resin material that can maintain a state of being submerged in water as well as a metal material.

Here, the detachable portion 30 is described as the guide groove 34 of the guide piece 32 wraps the wire 10 so that the bar check plate 20 is horizontal, but the bar check plate 20 Due to the weight of the detachable portion 30 coupled to the bottom, the bar check plate 20 may be horizontal. That is, the entire center of gravity of the bar check plate 20 and the detachable part 30 is located under the bar check plate 20 due to the detachable part 30. Therefore, the detachable part 30 is configured to pull the bar check plate 20 downward, so that the bar check plate 20 can be kept horizontal.

When the bar check plate 20 and the detachable part 30 described above are installed between the pair of stoppers 12 in order to fix the wires 10 at fixed set intervals, the pair of stoppers 12 may be out of the pair of stoppers 12. The bar check plate 20 and the detachable part 30 are installed on the wire 10 so that one is disposed at the upper end of the bar check plate 20 and the other stopper 12 is disposed at the lower end of the detachable part 30. do. Accordingly, the bar check plate 20 and the detachable part 30 may be prevented from moving up and down on the wire 10, thereby minimizing an error in sound velocity measurement.

The coupling means 40 is for coupling the bar check plate 20 and the detachable part 30, and is inserted into the through hole 22 of the bar check plate 20 to engage the coupling hole 33 of the coupling piece 31. ), A male thread 41 penetrating through the (), and a nut 42 engaged with the male screw 41. Accordingly, the bar check plate 20 can be detached from the wire 10 by detaching and coupling the detachable part 30 from the bar check plate 20 by loosening or tightening the nut 42.

Here, the coupling means, as shown in Figure 4, welds the external thread 41 'to the bottom of the bar check plate 20a, and fixed to the welded external thread 41' by attaching the removable portion 30 to the nut. You may. In addition, the coupling means 40 'forms the through hole 22' formed in the bar check plate 20b stepwise, and inserts a snap-fit 40 '(Snap-fit) into the bar check plate ( 20b) and the removable part 30 may be combined. As a result, the bar check plates 20a and 20b and the detachable part 30 can be quickly and easily coupled or separated.

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. .

However, since the bar check mechanism 1 according to the embodiment of the present invention can detach the bar check plate 20 from the wire 10, the bar check plate 20 may be combined as many times as necessary depending on the depth of the bar check plate 20. Therefore, the use of the straight wire 10 is possible. Thereby, there is no problem of the bending of a wire, and the accuracy of a sound velocity measurement improves. That is, in the case of a wire connected by a conventional loop, since the wire is connected by a ring, the ring connection portion between the wires is freely bent. Therefore, the looped portions between the wires are easily bent by current currents (water currents), so that the distance (or spacing) between the bar check plates is different from the originally intended distance (or spacing), thereby increasing the error of the sound velocity measurement. However, in the present invention, since there is no connection portion and uses a straight wire 10 formed continuously, it is possible to minimize the bending or bending of the wire 10 by current current, and furthermore, the bar check plate installed in the wire 10. By minimizing the movement of 20, the error of the sound velocity measurement can be minimized.

In addition, the bar check mechanism 1 of this invention can also change and adjust the space | interval between the bar check plates 20 as needed.

In describing the present invention described above, even if the embodiment is different, the same reference numerals are used for the same configuration, and the description may be omitted as necessary.
