Description

{A PROTECTOR FOR SOUND VELOCITY PROFILER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a sound velocity measuring device that is installed outside a sound velocity meter to protect a sound velocity meter.

Sound velocity in the sea is about 1500m / sec, but the sound speed changes by season, depth of water, water temperature, salinity and so on. Therefore, sound velocity can be measured in a sea area to investigate sound velocity distribution from the sea surface to the sea floor. The conventional method of measuring the sound velocity in the sea is as follows.

As shown in FIG. 1, a sound velocity profiler 20 (sound velocity profiler, abbreviated as "field" in the drawings) hangs on a cable 25 into a sea using a small crane (C) 'SVP'). The sonic sensor unit 21 of the sonic velocity meter 20 is operated from the water surface to the sea floor to measure the sound velocity.

The sound wave sensor unit 21 of the sound velocity meter 20 used in the prior art is usually located at the bottom of the apparatus.

Therefore, when the sonic speed meter 20 is excessively lowered to the bottom surface B due to an accident such as an operator's fault or a crane (C) malfunction, the sonic sensor unit 21 may be damaged. Also, when the sound velocity meter 20 arriving at the seabed surface B is laid down or when the sound wave sensor unit 21 is buried in sediments such as pearl or subsea garbage, the accuracy of the measurement is degraded and malfunctions are caused It is possible.

To solve this problem, the measuring instrument body and the sound wave sensor part 21 are protected when the sonic velocity meter 20 is dropped to the sea floor. When the sonic velocity sensor 20 reaches the bottom surface B, the sonic velocity meter 20 is supported A device is needed to ensure location.

<Example 1>

2 and 3, the sonic speed meter protective cover 10 according to the first embodiment includes a clamp 13 and a support member connected to and supported by the clamp 13. As shown in Fig.

In the first embodiment, two clamps 13 of the same shape are arranged vertically, and the first clamp 13a disposed at the upper portion and the second clamp 13b disposed at the lower portion are referred to as the upper clamp 13a.

The clamp 13 is configured to fix the sound measuring body 22 having an elongated cylindrical shape in the downward direction, respectively. The clamp 13 is constituted by a cylinder having an inner hole, and a bracket 14 for attaching and fixing the support to the outer surface of the cylinder is attached by welding or the like.

The fastening adjusting unit 30 is installed to penetrate the inside and the outside of the cylinder 13 of the clamp 13 in order to detach the sonic meter main body 22 to the clamp 13. At this time, the through hole 17 penetrating the inside and the outside of the cylinder of the clamp 13 is formed so that the inner surface of the hole has a smooth surface.

A support base to be connected and fixed to the bracket 14 of the clamp 13 is divided into an outer support base 11 and an inner support base 12. As shown in Figs. 2 and 3, the support members are respectively installed at three points around the outer periphery of the cylinder of the clamp 13. The outer support 11 thus forms a tripod so that the protector can stably stand up from the seabed. If necessary, the number of the outer supports 11 and the number of the inner supports 12 may be more than three, respectively, so that the outer supports 11 and the inner supports 12 may be formed to have a square or a rectangular base.

The outer support 11 may be formed of an elongated bar, a rod or a pipe, and one end thereof is fixed to the bracket 14 of the first clamp 13a by a coupling hole 15 and the other end is elongated obliquely toward the ground .

The inner support 12 may also be formed of a long bar, a rod or a pipe, and one end thereof is fixed to the bracket of the second clamp 13b by a coupling hole 15 and the other end is connected to the outer support 11 And is fixed by a coupling hole 16.

In the first embodiment shown in Fig. 3, the coupling holes 15 and 16 are shown as bolts and nuts, but the present invention is not limited thereto. For example, it may be replaced with a mechanical element such as a rivet, and if the bracket 14 is made of metal, it may be connected and fixed by welding.

It is also possible to omit the bracket 14 and directly fix the support to the cylinder of the clamp 13. That is, the cylinder 13 and the support member may be made of a metal material and welded directly.

The tightening control part 30 installed through the inside and the outside of the clamp 13 has a tightening plate 33, a bag part 32 and an adjusting part 31 as main components. This configuration is shown in greater detail in an enlarged cross-sectional view in Fig.

The clamping plate 33 is located inside the clamp 13 and serves to hold the clamping plate 33 against the outer surface of the sound measuring device body 22 to prevent it from moving. At this time, the fastening plate 33 may be formed to have an arc shape so that the sonic velocity measuring instrument body 22 can be held more easily.

A protective plate 34 may be attached to the outer surface of the tightening plate, that is, the surface that comes into contact with the outer surface of the sonic meter body 22. The protection plate 34 is formed of a soft material such as rubber and is used to prevent the sound speed meter from being damaged.

The bag portion 32 is a rod-shaped member that extends from the rear surface of the tightening plate 33 and penetrates through the through hole 17 of the clamp 13 and a part thereof is exposed to the outside of the clamp 13 . A thread is formed on the outer surface of the bag portion (32).

The adjuster 31 is screwed into the bag portion 32 exposed to the outside of the clamp 13, and a nut is used in the first embodiment.

3 shows the two fastening plates 33 and the two fastening plates 32 and the adjusting holes 31. The single fastening plate 33 is provided with the flaps 32 and the adjusting holes 31 ) May be formed.

In the first embodiment shown in FIG. 3, the tightening control unit 30 is disposed at a position where the circumference of the cylinder 13 is divided into three equal parts. However, the number and position of the tightening control unit 30 It is possible to appropriately change the design according to the design.

The operation of the first embodiment will be described with reference to Figs.

First, when the guard 10 is prepared as shown in FIG. 2, the adjusting member 31 is loosened so that the adjusting plate 33 can move back and forth along the smooth through-hole 17.

Subsequently, the body of the sonic velocity meter 20 is inserted from above so as to pass through the inside of the first clamp 13a and the second clamp 13b with the sensor portion 21 facing downward.

Next, the first and second clamps 13a and 13b of the second clamp 13b are pushed along the through hole 17, and when the tightening plate 33 comes into contact with the outer surface of the sound measuring instrument body 22 Tighten the adjusting member 31 using a screw thread formed on the outer surface of the bag portion 32 and fasten it.

3, the three fastening plates 33 are fixed in the first clamp 13a and the second clamp 13b while holding the torso of the sonic velocity meter 20 therebetween.

It is possible to prevent the sensor unit 21 from being lowered below the lower end position of the external support 11 when the sonic speed meter 20 is fixed, Should not touch the sea floor.

The body of the sonic velocity meter 20 shown in FIG. 3 has a cylindrical shape with an upper portion having a larger diameter and a lower portion having a smaller diameter. However, the sonic velocity meter 20 may be cylindrical with a constant diameter. However, according to the present invention, since the first clamp 13a and the tightening plate 33 provided on the second clamp 13b can be adjusted to have different diameters, they can be freely used in a sound velocity meter having a different shape of the body .

<Practical Example 2>

The invention of the first embodiment can not fold out the outer support 11 when the sonic velocity meter 20 is installed. Therefore, when the guard 10 is mounted on the sonic speed meter 20, other equipment may be caught on the outer support 11, or it may be damaged or hit by a person.

In order to prevent this, it is inconvenient to separate the sound velocity meter 20 from the protector in order to collapse and store or move the outer support 11 of the protector 10.

In the second embodiment of the present invention, as shown in FIGS. 4 to 6, a resistance-receiving member 40 is additionally provided to the protector 10 of the first embodiment. In the state where the sonic meter 20 is installed So that the outer support 11 can be folded.

Fig. 4 shows a resistance receiving member 40 used in the second embodiment.

The resistance receiving hole 40 is preferably formed by using a material having resistance to salt water such as stainless steel, which has a resistance portion 41, a stopper 42, and a rotation connecting hole 43.

The resistance portion 41 can be formed of a plate material having a large area so as to receive resistance of water when the guard 10 falls down in water. In Embodiment 2, the shape of the plate material is made into a spoon shape, To be more efficiently received.

The stopper 42 and the pivot connection 43 are portions extending from one end of the resistance portion 41.

In the second embodiment, one end of the resistance portion 41 is extended in the form of a rectangular plate, the extending portion is cut into three strands, and the middle strand is set up to form a stopper 42. The left and right strands of the stopper are round And a pair of pivot connection ports 43 formed with a through hole 44 in the center are formed.

Fig. 5 shows the structure of the guard 10 of the second embodiment.

The protector 10 of the second embodiment is different from the protector 10 of the first embodiment in that it has a configuration for installing the resistance-receiving part 40.

First, in the guard 10 of the second embodiment, a guide slot 19 is formed in the outer support 11 so that one end of the inner support 12 is slidably connected.

One end of the inner support 12 connected to the portion of the guide slot 19 of the outer support 11 has a width wider than that of the expander ' And has a formed portion. The reason why the 'c' portion is expanded is that the pivot connection 43 of the resistance receiving portion must be disposed in addition to the outer support portion 11 between the widths formed in the 'C' shape.

In Embodiment 2, the connection between the inner support 12 and the outer support 11 and the resistance receiving member 40 is as follows.

 First, a resistance receiving member 40 is disposed at a portion where the guide slot 19 of the external support 12 is formed to be sandwiched between the pair of pivot connection ports 43. Then, the pivot connector 43 is positioned between the extended 'C' portion 18 of the inner support 12. At this time, the resistance receiving hole 40 causes the stopper 42 to protrude upward, so that the concave portion of the resistance portion 41 faces toward the lower (sea floor) side.

In this state, one end of the inner support base 12 and the through hole 44 and the guide slot 19 of the pair of pivotal connection ports 43 are connected to each other through the coupling holes 16.

In this connection state, one end of the inner support 12 and the resistance receiving member 40 can move along the guide slot 19. The resistance receiving hole 40 is vertically rotatable about the coupling hole 16 inserted in the through hole 44 of the pivot connection hole 43 as a central axis.

The operation of the second embodiment will be described with reference to FIG.

The adjustment tool 31 of the prepared guard 10 is loosened to insert the sound velocity measuring instrument body 22 into the first and second clamps 13a and 13b and then the sound velocity meter 20 are fixed and installed in the same manner as in the first embodiment.

In Embodiment 2, the guard in a state in which the sound velocity meter 20 is installed can be stored and moved by folding the support as shown by the dotted line in FIG.

That is, the second clamp 13b fixing the sound velocity meter body 22 can not move, but one end of the inner support 12 extending from the second clamp 13b is inserted into the guide slot 19 of the outer support 11 So that the protector 10 can be folded by pulling the outer support 11 inward even when the sonic velocity meter 20 is installed.

The worker can conveniently move the protector 10 provided with the sound velocity meter to a required position on the line in a folded state. If the worker is not in operation, it can be stored in a corner so as not to interfere with the movement of a person.

When the sound velocity meter 10 is to be dropped into the sea for measurement, the guard 10 should be kept folded.

 During the descent of the protector 10 dropped into the water, the resistance portion 41 of the resistance-force receiving member 40 receives a resistance of water and generates a force to rise.

However, since the coupling part 16 is fitted in the pivotal connection part 43 formed at one end of the resistance receiving part 40, the resistance part 41 is rotated upwards around the coupling part 16 as a central axis.

The stopper 42 formed at one end of the resistance receiving member 40 abuts against the outer surface of the outer support 11 to stop the upward rotation of the resistance portion 41. [

If the resistance of the water continues to be applied to the resistance receiving hole 40 after the protector falls, the coupling hole 16 coupled to one end of the resistance receiving hole rises along the guide hole 19, 11 are pushed by the coupling member 16 and spread outward.

As described above, the second embodiment is advantageous in that even if the protective guard 10 is folded into the water in the folded state, the protector can be automatically spread and seated on the sea floor.

When the protector 10 is lifted up after the measurement operation is completed, the resistive force of water generated when the protector 10 is lifted and the self-weight of the resistive force receiving port 40 simultaneously act, (41) is turned downward to contact the outer surface of the outer support (11).

The engaging member 16 is lowered along the guide elongated hole 19 by the self weight of the inner support member and the resistance receiving member 40 while the protector 10 continues to be lifted out of the water.

As a result, the second embodiment has an advantage that the protector 10 is automatically folded as shown by the dotted line in Fig. 5 and pulled out of the water.

Example 1 of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention should be understood only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
