Description

Observation system for seabed by the sonar}

The present invention relates to a channel topography change surveying system through acoustic exploration.

In general, when performing fishing work, construction of marine buildings, military operations, and port operations in the ocean, information on the seabed topography is obtained using paper, electronic charts, and various electronic observation equipment. For example, a good understanding of the seabed topography irregularities in the construction of offshore structures is the starting point for designing offshore structures, from which the height of the offshore structure, the substructure of the structure, the vertical positioning of the ship's eyepiece, and the scope of the corrosion protection design, etc. And topographical stability of offshore structures.

To this end, the most widely used method is to obtain information about the seabed topography, such as the sea channel by using a sound wave detector or a sound detector. This method corresponds to a method in which a sound wave detector is installed on a ship to transmit sound waves toward the sea floor near the sea surface and then receive sound waves reflected from the sea bottom to obtain necessary information. However, this method is hampered by sea waves and the reflection of sound waves from fish or aquatic organisms, and thus takes a long time to repeat the exploration process several times. There are difficulties that occur frequently. In addition, in order to acquire data about the change of the seabed topography relatively accurately, it is necessary to repeat the transmission and reception of sound waves at a relatively constant position with respect to the seabed topography. Since it moves to this location and returns to the port after the exploration, it is practically impossible to send a sound wave by placing the sound wave detector at the same location as the previous exploration based on the exploration of the same seabed. As a result, there is a problem that it is difficult to obtain change data of the seabed topography.

The sound wave output devices are distributed and installed on the bottom of the sea, and then the signals of each sound wave output device are separated and received, so that the topographical change of the sea bottom is relatively accurate through analysis of data having continuity for a relatively long time. There is a need to develop a system for surveying terrain changes to sea channels by acoustic exploration. Patent No. 10-1492863 is a prior art in accordance with such a request, but the prior art has a problem in that an error occurs in communication when there is a small area to cover and there is no obstacle due to maneuverability in the sound wave output device.

The technical problem to be achieved by the technical idea of the present invention is to provide mobility to the sound wave output device to expand the area covered by one sound wave output device to improve the economics and efficiency, and to solve the communication error by moving the position when there is an obstacle, etc. It is to provide a channel topography change surveying system through acoustic exploration.

The sound wave detector 2000 may include a receiving module 2100 for receiving a signal of sound wave (sound) transmitted from the sound wave output apparatus 1000. Here, the conventional sound wave detector (SONAR; Sound Navigation And Ranging) may be used as the sound wave detector 2000, and the sound wave detector 2000 further includes a transmission module (not shown) for transmitting sound waves in addition to the receiving module 2100. can do. In this case, the sound wave output apparatus 1000 may transmit the sound wave signal including the time information (TIME STAMP) in which the sound wave signal is transmitted (output) by the built-in program, and the sound wave detector 2000 receives the sound wave (sound) signal. The method of analyzing the data may use a known technique, that is, analysis of transmission time and reception time information or analysis using a speed at which sound waves propagate underwater.

The location information calculation module 3000 analyzes the sound wave information received from the sound wave detector 2000 and calculates the relative position information of the sound wave detector 2000 by calculating based on the GPS position information of the mother body where the sound wave detector 2000 is installed. By using the identified position information of the plurality of sound wave output apparatuses 1000, numerical data for identifying a seabed topography may be obtained.

It may be displayed as a video based on or to be sequentially displayed by the input control signal, it can be displayed in a generally known manner.

The drawing module 7000 may show, as an image, the topography of the sea floor on which the corresponding sound wave output devices 1000 are installed, based on the location information of the sound wave output devices 1000 output through the controller 5000.

In this way, the plurality of sound wave output devices 1000 installed at a predetermined interval on the bottom surface transmit unique sound waves identifiable for each sound wave output device 1000, and receive them from the sound wave detector 2000, thereby providing each sound wave output device 1000. It can be classified and analyzed by each, so that the state of the topography changes of the sea floors in which the sound wave output device 1000 is installed can be relatively accurately identified through analysis of data having continuity for a relatively long time. This information is used as information for fishing operations, construction of offshore buildings, military operations and port operations, and can be used to produce relatively accurate electronic charts and paper submarine maps. In this case, when each sound wave output apparatus 1000 transmits the same sound wave (sound) signal, each sound wave output apparatus 1000 may include (or transmit) a unique number for identifying itself in the sound wave (sound) signal. have.

Shown in the figure).

The main body 1300 may have a substantially hexahedral shape and accommodate a configuration of a sound wave output module 1100 and a sound wave output control unit 1200 therein. In addition, the block portion 1400 may be configured to be connected to each of the four lower four corner areas of the main body portion 1300 and may serve as a leg to separate the main body portion 1300 from the sea floor at a predetermined interval, The fixing unit 1500 (shown in FIG. 3) may serve to fix the sound wave output device 1000 to the sea bottom.

3 is a cross-sectional view illustrating the block unit 1400 and the fixing unit 1500 of the sound wave output apparatus 1000 illustrated in FIG. 2. Hereinafter, the fixing unit 1500 of the sound wave output apparatus 1000 according to the present embodiment will be described with reference to the embodiment.

As shown in FIG. 3, the fixing unit 1500 of the sound wave output apparatus 1000 according to the present embodiment extends from below each of the four block portions 1400 to fix the sound wave output apparatus 1000 to the sea bottom. Can be. Specifically, the fixing unit 1500 may be implemented in a multi-stage structure, such as an antenna, the entire length is stretchable, specifically, the first fixing unit 1510, the second fixing unit 1520 and the third fixing unit 1530 Consists of three stages, and may include an elastic member (1540) for driving elastically.

At this time, the first holder 1510 is received and fixed to the receiving groove 1410 formed in the center of the block portion 1400, the second holder 1520 is one end of the first hollow 1511 of the first holder 1510 The other end may be adjacent to or away from the first fixing unit 1510, and one end of the third fixing unit 1530 may be inserted into the second hollow 1521 of the second fixing unit 1520, and the other end thereof may be inserted into the second fixing unit 1510. It may be adjacent or far from 1520. At this time, the third fixing stand 1530 may include a region that is narrower toward the end at least in part to be easily embedded in the sea bottom.

In addition, one side of the elastic member 1540 is fixed in the first holder 1510 or the block portion 1400 and the other side is connected to the third holder 1530, the third holder 1530 to the first holder 1510 The fixing part 1500 may be elastically implemented by pulling in the direction of the direction or pushing the opposite direction. At this time, the length of each fixing rod is shorter than the length of the block portion 1400, when the "reduced state" as shown in Figure 3 (a), the fixing portion 1500 is to be accommodated in all the receiving groove 1410 of the block portion 1400 In the “extended state” as illustrated in FIG. 3B, the second fixing stand 1520 and the third fixing stand 1530 may protrude from the lower end of the block portion 1400 and may be embedded in the sea bottom. The operation of the "reduced state" and "extended state" can be made by the sound wave output control unit 1200 controls the expansion and contraction member 1540.

As described above, the three parts of the fixing unit 1500 are accommodated within the length of the limited block unit 1400, but protrude as long as possible so that the sound wave output device 1000 can be stably fixed to the sea bottom. It may be for the following. In addition, in order to fix the more stable sound wave output device 1000, each guide may be implemented in a square pillar shape.

4 is a cross-sectional view illustrating a part of the fixing part 1500 illustrated in FIG. 3. Hereinafter, the fixing part 1500 according to the present embodiment will be described in more detail with reference to FIGS. 3 and 4.

As shown in FIG. 4A, a rail protrusion 1522 is formed inside the second holder 1520 so that the third holder 1530 can easily slide from the second holder 1520. Rail grooves 1534 may be formed on the outer side of each surface of the holder 1530. At this time, the rail protrusion 1522 may implement a sliding method in a state in which the rail groove 1534 is inserted, and the third holder 1530 is easily slid from the second holder 1520 so that the fixing part 1500 is stretched. This may be possible. In this case, the outermost width 1535 of the rail groove 1534 may be implemented to be narrower than the maximum width 1536 to prevent the rail groove 1534 from being separated from the rail groove 1534. In addition, the structure of the rail protrusion 1522 and the rail groove 1534 may be applicable not only between the second holder 1520 and the third holder 1530 but also between the first holder 1510 and the second holder 1520. have.

On the other hand, as shown in Figure 4 (b), the third holder 1530 of the fixing unit 1500 according to the present embodiment may be provided with a plurality of fixing grooves 1533 extending in the longitudinal direction on the outer surface. have. In addition, the branch 1539 may be seated in the fixing groove 1533, the branch 1539 may be coupled to the other end of the third fixing stand 1530 in the hinge (1537a, 1537b) structure, respectively. Accordingly, the branch 1539 is folded to hinge the branch 1539 and the "folded state" (see FIG. 3 (b)) in which the entire branch 1539 is seated in the fixing groove 1533. By unfolding by reference, the other end of the branch 1539 can be implemented in the "expanded state" (see Fig. 4 (b)) is released from the fixed groove 1533, such a "folded state" and "unfolded state" The control of the sound wave output control unit 1200 may be made.

In this case, when the "expanded state" is compared to the "folded state" as shown in FIG. 3 (b), the branching band 1539 is unfolded and additionally embedded in the sea floor, so that the sound wave output device 1000 is more firmly fixed to the sea bottom. can do. In this case, in order to improve the fixing force, it may be possible to have a structure in which the branching band 1539 becomes wider toward the end (see FIG. 4A). In addition, when the “folded state”, that is, the branch 1539 is seated in the fixing groove 1533, the surface of the branch 1539 and the surface of the third fixing table 1530 are in the same plane. As in b), when the third fixing bar 1530 is extended, the fixing part 1500 may be easily embedded in the sea bottom.

The 1539 may include a first branch 1537 seated in the first fixing recess 1531 and a second branch 1538 seated in the second fixing recess 1532. At this time, the first hinge 1537a, in which the first branch 1537 is connected to the third fixing bar 1530, is positioned under the first branch 1537, and the second branch 1538 is the third fixing bar ( The second hinge 1538a connected to the 1530 may be located above the second branch 1538. That is, the direction in which the first branch 1537 and the second branch 1538 are unfolded may be opposite to each other, and accordingly, a more powerful bottom surface may be fixed according to a complementary effect. On the other hand, the first branch 1537 and the second branch 1538 may be implemented in four on each side of each of the third fixing stand 1530 implemented in a square pillar shape, it is formed in a position corresponding to each other in the figure Although illustrated as being to be overlapping with each other, it is also possible to arrange, and in this case it can further improve the fixing force to the bottom according to the complementary effect.

FIG. 5 is a side view illustrating the wheel unit 1600 and the lifting unit 1700 of the sound wave output apparatus 1000 illustrated in FIG. 2. Hereinafter, the wheel unit 1600 and the elevation unit 1700 according to the present embodiment will be described with reference to FIGS. 2 and 5.

As shown in FIG. 2 and FIG. 5, the wheel part 1600 may be connected to four vertex areas below the main body part 1300, respectively, and implemented in four. In addition, the lifting unit 1700 may be installed between the wheel unit 1600 and the main body unit 1300, for example, a cylinder or the like for raising and lowering the wheel unit 1600. At this time, when the lifting unit 1700 ascends the wheel portion 1600 as shown in Figure 5 (a), the block portion 1400 may be in the "elevation state" to reach the bottom, as shown in Figure 5 (b) When the 1700 lowers the wheel part 1600, the block part 1400 may be in a "falling state" spaced apart from the sea bottom by the lowered wheel part 1600. In this state, when the wheel unit 1600 is driven, the position of the sound wave output apparatus 1000 may be changed to a "moving state". The control of the "lift state", "fall state" and "moving state" may be made by the sound wave output control unit 1200.

As described above, in the present exemplary embodiment, the wheel part 1600 and the elevating part 1700 may be used to impart mobility to the sound wave output device 100. In the past, since the sound wave output device 1000 was fixed type, the area area that can be covered by one sound wave output device 1000 was limited. In this embodiment, one sound wave is provided because the sound wave output device 1000 is maneuverable. The area that the output device 1000 can cover can be effectively widened compared to the existing. Therefore, the number of sound wave output devices 1000 in the entire system can be reduced, thereby improving economic efficiency and efficiency.

In addition, when an error occurs in the communication between the sound wave output device 1000 and the sound wave detector 2000 due to an obstacle, the position of the sound wave output device 1000 may be changed to solve the communication error.

The manner in which the sound wave output control unit 1200 controls the movement and fixation of the sound wave output device 1000 as described above is as follows.

When the sound wave output device 1000 is fixed in the first position and the sound wave output device 1000 is moved to the second position, the sound wave output control unit 1200 first folds the branching branch 1539 that is extended. It is possible to control the branch 1539 in a "folded state" to allow the 1539 to be seated in the fixing groove 1533 of the third holder 1530 (Fig. 3 (b) state). At this time, since the branching band 1539 releases the fixing to the sea bottom, the sound wave output device 1000 is fixed only by the second fixing bar 1520 and the third fixing bar 1530, so that the branching basin 1539 is fixed to the bottom of the sea floor compared to the "open state". The holding force may drop.

Next, the sound wave output control unit 1200 may control the expansion and contraction member 1540 to reduce the fixing unit 1500 to control the reduced state to accommodate the fixing unit 1500 in the block portion (FIG. 3 (a). ) condition). In this case, when the fixing unit 1500 is reduced, the fixing to the sea bottom is released, so that the sound wave output device 1000 may be viewed as simply placed on the sea bottom.

Next, the sound wave output control unit 1200 may control the lifting unit 1700 in the "falling state" so that the block unit 1400 is separated from the sea floor by lowering the wheel unit 1600 (Fig. 5 ( b) status).

Next, the sound wave output control unit 1200 may drive the wheel 1600 to control the "moving state" to move the position of the sound wave output device 1000.

Next, when the sound wave output device 1000 is moved to the second position, the sound wave output control unit 1200 controls the lifting unit 1700 to lift and lower the wheel unit 1600 to lower the block unit 1400 on the sea bottom. It can be controlled to the "elevated state" (Fig. 5 (a) state).

Next, the sound wave output control unit 1200 extends the fixing unit 1500 by controlling the stretchable member 1540 so that the second fixing unit 1520 and the third fixing unit 1530 protrude from the lower end of the block unit 1400 to the seabed. It can be controlled in the "extended state" to be stuck to the surface (Fig. In this case, the sound wave output apparatus 1000 may be fixed on the bottom of the sea.

Next, the sound wave output control unit 1200 unfolds the branch 1539 so that the branch 1539 is separated from the fixing groove 1533 of the third fixing stand 1530 so that the branch 1539 is further embedded in the sea bottom. It can be controlled in an "unfolded state", thereby firmly completing the fixing of the sound wave output device 1000 in the moved second position.

6 is a cross-sectional view for describing the power generator 1800 and the battery unit 1900 of the sound wave output apparatus 1000 illustrated in FIG. 2. Hereinafter, the power generation unit 1800 and the battery unit 1900 according to the present embodiment will be described with reference to this.

The power generation unit 1800 is a member that generates power, and the power produced by the power generation unit 1800 may be stored in the battery unit 1900. The power generation unit 1800 may include a vibration bar 1810, a sealing member 1820, a first magnet 1830, a coil 1840, a second magnet 1850, and a third magnet 1860. . The vibrating bar 1810 is connected to penetrate the outer wall surface of the main body 1300 so that one end 1811 of both ends is located outside the main body 1300 and the other end 1812 is located inside the main body 1300. Can be.

When the vibrating bar 1810 penetrates the main body 1300, seawater may flow into the main body 1300, and thus, the main body 1300 and the vibrating bar may be maintained to maintain a waterproof state inside the main body 1300. The sealing member 1820 may be positioned between the 1810. At this time, in consideration of the high water pressure of the seabed, it is preferable to set the waterproof to the maximum. In this embodiment, the waterproof system can be implemented as follows.

In detail, an insertion hole 1310 into which the vibration bar 1810 is inserted is formed in the main body 1300, and the first sealing groove 1320 is formed in each of the outside and the inside of the insertion hole 1310 so as to be spaced apart from each other. Can be formed. That is, the first sealing groove 1320 may be formed in four places and may be formed to be recessed toward the inside. In this case, the first sealing groove 1320 may be embodied in a stepped shape. Specifically, the first sealing groove 1320 is located deeper and farther from the surface than the first groove region 1321 and the first groove region 1321 adjacent to the surface. It may include a second groove region 1322 stepped from the first groove region 1321 to be wider. In the case of the stepped configuration as described above, since the path of penetration of moisture in the seawater becomes longer, the waterproofing ability may be further improved. In addition, a second sealing groove 1813 may be formed in an upper part and a lower part of the surface of the vibrating bar 1810 facing the insertion hole 1310, and the second sealing groove 1813 also includes the first sealing groove 1320. Like), the deeper the width, the wider the stepped shape to improve waterproof.

The sealing member 1820 may include a first sealing area 1821 in close contact with the outside of the main body 1300, a second sealing area 1822 and a first sealing area 1821 in close contact with the inside of the main body 1300, and the sealing member 1820. It may include a third sealing region (1823) in close contact with the inside of the insertion hole 1310 while connecting between the second sealing region (1822), it may be made of a material having elasticity. In addition, the first sealing region 1721 and the second sealing region 1822 have a protruding shape, but the first protrusion 1824 having a stepped shape is widened so as to protrude to correspond to the first sealing groove 1320. Formed to be in close contact with the first sealing groove 1320 to achieve waterproofing, and have a protruding shape in the third sealing region 1823 but protrude to correspond to the second sealing groove 1813 to have a wider stepped shape. The second protrusion 1825 is formed to be in close contact with the second sealing groove 1813 to realize waterproofing. In this case, the first protrusion 1824 is positioned to protrude from the surface than the first protruding region 1826 and the first protruding region 1826 adjacent to the surface, and is stepped from the first protruding region 1826 so as to have a wider width. It may be configured to include a second protruding region 1827, and the second protrusion 1825 may also have a stepped structure that is wider as it protrudes, thereby improving waterproofing.

On the other hand, the first magnet 1830 is coupled to any one surface of both sides of the other end 1812 of the vibration bar 1810, the coil 1840 is the other end 1812 of the vibration bar 1810 inside the body portion 1300 It can be installed spaced apart from. In addition, the second magnet 1850 is installed to be spaced apart from the coil 1840 on the opposite side of the vibration bar 1810 so that the direction adjacent to the coil 1840 is the S pole, and the third magnet 1860 is the second magnet 1850. It may be installed so that the direction adjacent to the coil 1840 is the N pole in the lower portion.

In this structure, when a natural tidal current is generated outside the sound wave output device 1000, one end 1811 of the vibration bar 1810 located outside the main body unit 1300 is vibrated, and the vibration is performed at the other end of the vibration bar 1810. 1812, the magnetic flux inside the coil is changed while the other end portion 1812 of the vibration bar 1810 moves vertically in the vertical direction, thereby generating an AC voltage. In this case, the second magnets 1850 and the third magnets 1860 have different polarities toward the coils 1840 so that the magnetic flux change amount of the coils 1840 increases when the vibration bar 1810 vibrates, thereby increasing the coils 1840. Can increase the output voltage. Specifically, when the vibration bar 1810 is vibrated upward, the magnetic flux density in the coil 1840 is increased by the first magnet 1830 and the second magnet 1850, and the N pole and the first pole of the first magnet 1830 are increased. The magnetic flux density in the coil 1840 may increase due to the attraction force due to the S pole of the two magnets 1850. That is, the magnetic field emitted from the N pole of the first magnet 1830 converges to the S pole of the second magnet 1850, so that the magnetic flux density in the coil 1840 may be increased. In addition, when the vibration bar 1810 is vibrated downward, the magnetic flux density in the coil 1840 is reduced by the first magnet 1830 and the third magnet 1860, and the N pole and the second magnet 1850 of the first magnet are reduced. Magnetic flux density in the coil 1840 may be reduced by the repulsive force according to the N pole of the (). That is, the magnetic field emitted from the N pole of the first magnet 1830 may be canceled by the magnetic field emitted from the N pole of the third magnet 1860, thereby reducing the magnetic flux density in the coil 1840. As such, when the vibration bar 1810 is vibrated upward, the magnetic flux density may be maximized, and when the vibration bar 1810 is vibrated downward, the magnetic flux density may be minimized. Accordingly, the variation of the magnetic flux in the coil 1840 with time may be maximized.

In this case, the AC voltage output from the coil 1840 may be converted into a DC voltage by a separate rectifier. The generated electrical energy is stored in the battery unit 1900 and then the sound wave output module 1100 and the sound wave output control unit 1200. ), The fixing unit 1500, the elevating unit 1700 and the wheel 1600 may be used as energy when driving.

In addition, by installing the power production unit 1800 according to the present embodiment on all four sides of the main body unit 1300, it is possible to continuously produce power regardless of the current changes depending on time and season, sound wave output device 1000 Can produce enough power to continue running without a separate power supply.
