Description

A sea-bottom search system and method using a stop rope for deep diving}

The present invention relates to a large depth underwater survey system and method using a decompression rope for diving in depth, and more specifically, a diver can accurately dive into the survey area even in an area where there is algae and high digging during the large depth underwater survey. In the event of an emergency by providing the convenience of the diver to follow the decompression schedule until after the investigation and ascending to the surface, with the help of emergency supply gas, support divers and emergency decompression tables. The present invention relates to a large depth underwater survey system and method using a deep diving pressure reducing rope that allows a diver to safely climb to the surface.

In general, a deep dive is conducted at a depth of 40 to 100 m or more, and divers must safely attach the necessary equipment to the body and dive, and use the ascending and descending ropes and bird hooks for digging and descending algae. Accidents such as deviations from decompression depth, missing and net jams caused by horizontal algae, collisions with other ships, etc. should be prevented in advance, and accurate decompression utilization lines should be used even when climbing to reduce the risk of decompression sickness. It's a very high risk dive.

Therefore, the large depth underwater survey by this large depth diving is difficult to investigate and travels in many areas and is limited by the survey time. It is very important to climb.

However, existing underwater surveys by deep-dive diving were possible only in environments with low tidal currents and high digging, due to the high probability of failure and the lack of safety measures due to the lack of empirical and scientific approaches. In areas with high tidal currents and high digging, it is difficult to find an accurate range of coverage, which makes it difficult to survey within the range of coverage, as well as the likelihood of problems such as divers failing to climb safely in an emergency. In particular, underwater surveys by deep-water diving in Korea are difficult to proceed except when the sea is low or the tide is weak, and it is very difficult to find the exact survey area. In particular, in the deep-depth diving that does not use bird hooks, many people dive or fail outside the survey area because they cannot overcome the resistance of birds. There is a possibility that the momentary loss of physical strength and the birds can not leave the place because of the resistance to the resistance.

Therefore, divers who participate in a deep-depth underwater survey by deep-dive diving can safely guide the diver to follow the exact decompression schedule while ensuring that they can safely climb to the water surface without missing birds or colliding with nets and boats. A device is indispensable.

The technical problem to be solved by the present invention is to allow divers to dive accurately into the surveyed area even in the presence of algae and high digging during deep-water diving, and to decompress the water until it rises to the surface after the survey. Emergency supply gas, support divers, and emergency decompression tables provide the convenience of accurately following the decompression schedule, allowing you to safely dive, and also allow you to safely climb the surface in the event of an emergency. It is to provide a deep underwater survey system and method using a decompression rope for diving.

In order to achieve the above object, an embodiment of the present invention is a submarine search vessel in which an anchor is lowered to an underwater survey target point to set a descent line, a submarine search vessel for submarine search, It is fixed by the decompression rope for the diving, and the knot which can install the diving ship, the safe decompression and the emergency facilities to be used for the transport of the diver and the diver, Is attached to the end of the pressure reducing rope for high degree of diving and descends into the water together with the weight to the maximum depth by the pressure reducing rope for high degree of diving, An underwater photographing equipment installed detachably so that an underwater photographing diver can be detached and attached to a body, and Depth of depth Deep diving using a decompression rope for deep-depth diving, which includes a decompression station which is installed at a position spaced upward from the end of the die-cost decompression rope and has at least one emergency decompression tank filled with a decompression emergency gas. Investigation system.

Another embodiment of the present invention for achieving the above object is to install a descending line to lower the target position lighting device and anchor on the seabed of the target point for underwater irradiation and to reduce the depth of the diving rope for the deep diving along the descending line Installation step for installing the decompression station and equipment necessary for decompression, lowering and underwater survey by means of the above-mentioned underwater diving survey and underwater photographing guide and support diver. Underwater survey step to conduct survey at the target point of underwater survey through use, and after completion of underwater survey, sequential rise of decompression line using knot of descending line and deep diving diving rope and emergency equipment provided at the decompression station part A large depth underwater survey method using a decompression rope for deep diving, including an ascending step.

According to the large depth underwater survey system and method using the large depth diving pressure reducing rope according to the present invention, by using two vessels each one vessel to install the exact search position and descending line, and to another vessel The deep diving diving decompression rope to help divers enter / exit along the descent line guides the diver to dive into the survey area precisely, so that divers can easily descend to the survey area. .

In addition, according to the present invention, since the decompression rope for deep-depth diving equipped with emergency facilities is installed in the descending line, it is possible to prevent the divers from disappearing or collide with the net and the ship, and the diver to the accurate decompression schedule It provides the convenience to protect the body, and also reduces the diver's stamina loss, so that the emergency supply gas, support divers, emergency decompression table and so on until you reach the surface, you can safely finish diving.

In addition, according to the present invention, since the bird hook is attached to the decompression rope for deep-depth diving can catch and support the body of the diver floating by the bird, thereby maintaining a constant distance between the diver and the descending line of the water surface Most of the deep sea divers who have a lot of equipment can help divers easily enter the survey area irrespective of algae.

In addition, according to the present invention, since diving is carried out using a decompression rope for deep diving and emergency facilities provided therein, a team can be found in an area where algae flows and high digging to find an accurate range of investigation and survey within a range. Divers have the advantage of being able to guide them safely up in the event of an accident.

On the other hand, in the ascending step, if the target position confirming lighting device 13 or the lowering line is not found, the underwater position guide buoyed by the guide diver and the falling position display buoy tied to the emergency rope (c3), The first and second decompression tanks filled with the first pressure-reducing mixture and the second emergency decompression tanks filled with pure oxygen for secondary decompression were used by the surface support diver (total supervision) and the decompression support diver who were waiting at the surface. (C4) attaching to a knot at a position corresponding to the first decompression station portion and the second decompression station portion of the decompression rope, respectively, and descending along the emergency rope to which the lowering position indicator is connected; One tank and one second decompression tank are delivered to the underwater survey diver, the underwater guidance guide, and the support diver to determine whether or not the decompression gas is used. Until, checking the server state to complete the decompression can be performed by a step (c5) to reduced pressure to increase along with an emergency pressure-rope.

The overall operation of a large depth underwater survey system and method using a large depth diving pressure reducing rope according to the present invention of this configuration will be described.

First, in the seabed navigation vessel (10) to lower the target position checking the lighting device 13 and the anchor 12 on the seabed of the target point for underwater surveys to install a descending line, the knot necessary for decompression rising at regular intervals Decompression ropes (50, 60), bird hooks (71,72), lighting device (53) for checking the lowering position and underwater photographing equipment (40) are attached to each other and install the facilities necessary for decompression, lowering and underwater survey from the bottom of the water to the highest depth position of the decompression rope (30) for deep diving.

After that, a first-in-class diver is obtained with a single system (one tank) and one pure oxygen tank (100% oxygen) by using the diving vessel 20, and then to the second decompression station unit 60 at a depth of 6 m. Descend. After checking the depth of water here, the 100% pure oxygen tank taken and 2 emergency decompression tanks (61a, 61b; 100% oxygen tanks) (3 total), which were sent down in advance, were used for the second decompression station of 6m depth. Depth of (60) is attached to and detachably attached to the knot of the decompression rope (30) for diving. When the fixing is completed, it descends again to check the depth of the first decompression station unit 50 at a depth of 21 m, and the emergency first decompression tank filled with a primary pressure reducing gas mixed with 50% oxygen and 50% nitrogen concentration. (51a, 51b) Check the attachment state of the two, and also confirm the operation and correct attachment of the underwater survey equipment 40 attached to the 30m point, the highest depth. After this check, the decompression rises and the attachment state is reported before exiting.

Next, the underwater shooting survey diver, the underwater shooting guide, and the support diver obtain the bird hangers (71,72) on the harness of the chest, respectively, and pull the bird hangers, respectively, to illuminate and lower the lighting device (53) for checking the descending position. Find the line and descend to the depth of 30m, the highest depth position of the decompression rope (30) for deep diving. At this time, the two divers obtain a double tank (trimix) and a decompression tank (for diving more than 70m). When the depth reaches the depth of 30m, which is the maximum depth of the decompression rope for diving (30), it is attached to the end of the decompression rope (30) for deep diving, and detached the underwater photographing survey equipment (40) previously sent down to the depth of 30m Attached to the body and again find the lighting and descending line of the illumination device 13 for the target position to descend to the bottom depth of the seabed.

When such a process arrives at the bottom of the seabed requiring underwater surveys, the underwater diving guide support divers conduct a deep survey on the target point of the seabed through the underwater shooting guidance and support by the support diver. At this time, the underwater shooting guide and the support diver guide the underwater shooting guide support diver by checking the survey contents of the target point, and always keep an eye on the rising line so as not to get lost. The direction must be carved. Through this process, after the depth underwater survey and survey is completed, the descending line with anchor is found and withdrawn.

In this case, if the descending line is found normally, the seam rises from the sea bottom to the depth of 30m, which is the end of the decompression rope 30, using the normal decompression procedure. By using the knot of the decompression rope 30 for diving deeply, the decompression rises while keeping the decompression depth conveniently. In the process, when the gas is low on the tank or a problem in the gas supply, the first emergency decompression tanks 51a and 51b provided in the first decompression station 50 at a depth of 21 m are removed and the primary The tank necessary for decompression can be replaced, and thus the decompression use tank is mounted on the knot of the decompression rope 30 for deep diving. Next, the replacement and detachment of the second emergency decompression tanks 61a and 61b provided in the second decompression station unit 60 at a depth of 6 m is repeatedly used in the same process as in the above, while the underwater photographing diver and Underwater guides and support divers will be able to safely decompress to the surface.

On the other hand, when the target position confirming lighting device 13 or the falling line is not normally found in the ascending step, firstly, the underwater position guide buoy and the falling position display buoy that the support diver has are tied to the emergency rope and run to the surface of the water. Then, the water support diver (general supervision) and the decompression support diver, which were waiting on the diving vessel 20 on the surface of the water, were equipped with two emergency first decompression tanks filled with a primary decompression gas mixture and a secondary oxygen decompression pure oxygen charge. Two second decompression tanks are attached to the 6m knot and the 21m knot of the emergency decompression rope, respectively, and descend along the emergency rope to which the lowering position indicator buoy is connected. When descending along the descending position indicator buoys and ropes, it will be possible to meet the underwater survey diver, the underwater guidance and support diver, and when they meet, the emergency first and second decompression tanks obtained with them. One by one to the underwater survey diver and the underwater guide and support divers to check the use of decompression gas and the status of each diver can be decompressed together using an emergency decompression rope until the pressure is safely completed.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above-described embodiments, which can be variously modified and modified by those skilled in the art to which the present invention pertains. Modifications are possible. Accordingly, it is intended that the scope of the invention be defined by the claims appended hereto, and that all equivalent or equivalent variations thereof fall within the scope of the present invention.
