Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a system for updating topographic information of a seawater,

[0001] The present invention relates to a system for confirming a change in the shape of a seawater to sea water through acoustical exploration and a system for updating the undersea topography information. More particularly, Even if the wire connecting the probe and the underwater detector is disconnected, it is possible to prevent the loss of the underwater detector and to save the time and labor to find the expensive underwater detector, And a system for updating the undersea topography information.

In general, the investigation of the change of the seabed topography is carried out by dragging the underwater detector to the exploration vessel and confirming the change of the topography through the submarine image generated from the underwater detector.

An "underwater detector" of the Korean Utility Model Registration No. 20-0415471 is known for confirming the change of the terrain.

The underwater detector generates an undersea image corresponding to the undersea topography while being dragged by the survey vessel.

However, the above-mentioned underwater detector is liable to be lost when the underwater detector is settled down when the wire connecting to the exploration vessel is disconnected.

Therefore, much time and labor were spent to find expensive underwater detectors.

Accordingly, there has been a demand for a confirmation of the change in the topography of the seawater and a system for updating the undersea topography information, which can prevent the loss of the underwater detector and confirm the seabed topography stably.

As a method for solving this problem, Korean Patent Registration No. 10-0936467, entitled " Confirmation of change in topography to sea water through acoustic survey and update of undersea topography information "has been disclosed.

The patent registration No. 10-0936467 has a float device and a marking device on the detector body of the underwater detector so that even if the connection of the wire connecting the underwater detector and the survey vessel is broken, the underwater detector can be easily found have.

That is, when the underwater detector is submerged due to the long lifetime use of the underwater detector or other external force, the control unit opens the float valve and expands the buoyant body with high pressure compressed gas, So that the underwater detector can float to the surface of the water.

In addition, the buoyant body is stored in the detector body before the use, that is, before the expansion, by the first lid. When the buoyant body is used, that is, when the buoyant body is expanded, the first lid is automatically opened by the expansion force of the buoyant body, To be exposed.

However, when the first lid is opened smoothly when the buoyant body is inflated, and when the fixed state of the first lid is weakly set, the first lid is easily opened and lost due to vibration or shaking during use of the underwater detector Of course, there is a problem that the buoyant body stored in the detector body of the underwater detector is exposed and damaged.

On the other hand, when the first lid is fixed too tightly, the first lid may not automatically open due to the expansion force of the buoyant body, which may cause malfunction. To reliably open the first lid, In the case of increasing the expansion force of the buoyant body, there is a risk of tearing or explosion due to the rapid expansion of the buoyant body, so that the buoyant body can not be raised beyond a certain pressure.

When the underwater detector 100 and the surveying apparatus 200 are located at a place where the undersea topography is to be confirmed and the survey vessel 210 is moved forward, And is guided by the exploration vessel 210 to move underwater.

At this time, as the underwater detector 100 sinks, the water pressure measured by the water pressure sensor 170 changes and a water pressure signal corresponding to the changed water pressure is transmitted from the water pressure sensor 170 to the control unit 180.

Here, when the control unit 180 receives the hydraulic pressure signal indicating that the measured hydraulic pressure is out of the reference value, the control unit 180 opens the floating device valve 124.

Therefore, as shown in FIG. 7, the illumination lamp 162 is exposed to the outside, and the illumination of the illumination lamp 162 is emitted to the outside.

Accordingly, the administrator can easily find the lost underwater detector 100 even in a dark place through the illumination of the illumination lamp 162. [

On the other hand, when the submarine topographical confirmation operation is completed, the underwater detector 100 must be moved to the exploration vessel 210.

At the same time, by the movement of the first lid 113 to be separated from the buoyant body mounting portion 112 by the expansion force of the buoyant body 126, the first projection portion 113a is pressed The first insertion bar 113b is further elastically deformed by the expansion force of the buoyant body 126 acting on the first lid 113 so as to move to the inclined surface 193b of the pressing portion 193 The first lid 113 can be opened smoothly and reliably because the lid 193b rides over the inclined surface 193b.

Since the first lid 113 is connected to the detector body 110 by the connecting line 198, the first lid 113 can be reused after recovering the underwater detector 100 without being lost when the first detachable lid is released. The first moving part 113a of the first lid 113 is engaged with the first engaging part 112a of the buoyant body mounting part 112. Therefore, the first moving part 194 of the first lid 113 is retracted by the resilient restoring force of the elastic member 195, And can be reattached.

The lid opening assisting device 190 according to the present invention functions in such a manner that the first insertion bar 113b is reliably elastically deformed so as to release the engagement of the first protrusion 113a when the first lid 113 is opened The first lid 113 can not be opened unexpectedly and the first lid 113 can be inflated excessively due to the elastic deformation of the first insertion bar 113b depending on the expansion force of the buoyant body 126 It is possible to prevent the buoyant body 126 from being torn or the like.

That is, when the buoyant body 126 is inflated and the first lid 113 is urged upward, only the expansion force of the buoyant body 126 depends on the expansion force of the buoyant body 126, The first insertion bar 113b may not be elastically deformed in accordance with the distribution of the first insertion portion 113a on the upper plate of the first cover portion 112a and the hooking structure of the first hook portion 112a and the first projection portion 113a is hooked, 113, the first engaging portion 112a and the first protrusion 113a are in close contact with each other, so that the elastic deformation of the first insertion bar 113b becomes more difficult.

In this case, when the first lug 113a is not released from the first latching part 112a and the first lid 113 is not opened immediately, the first lug 113 is not opened due to the expansion force applied to the buoyant body 126 113 may be broken and the buoyant body 126 may be torn and the function thereof may be lost.

When the engaging structure of the first projecting portion 113a and the first engaging portion 112a is formed to be easily releasable even with a small expansion force of the buoyant body 126, There is a possibility that the buoyant body 126 may be exposed from the detector body 110 and damaged due to vibration or weak vibration during use of the underwater detector.

Therefore, the lid opening assisting device 190 of the present invention makes the lid structure of the first lid 113 and the first latching portion 112a firm, And the first lid 113 can be opened reliably when the lifting device 120 is operated by disconnecting the underwater detector 100 so that the function of the lifting device 120 can be smoothly performed Can also be used to make sure.
