4 to 9 are views showing the operation of the seabed information confirmation system according to the present invention, the operation of the seabed information confirmation system according to the present invention with reference to Figs.

First, after placing the underwater detector 100 and the probe 200 in a place to check the seabed topography, and moving the probe 210 forward, the underwater detector 100 is more than the probe 210 It is arranged at the rear and is guided by the probe 210 to move underwater.

At this time, the distance measuring unit 130 transmits ultrasonic waves to the sea floor, receives the reflected wave back, outputs a distance measurement signal for the measured seabed topography, and the transmitting unit 150 receiving the distance measurement signal is This is wirelessly transmitted to the outside. In addition, the position tracking device 140 outputs a position measurement signal indicating the current position, and the transmission unit 150 receiving the position measurement signal is wirelessly transmitted to the outside.

When the distance measurement signal and the position measurement signal are output from the transmitting unit 150, the receiving unit 240 of the probe 200 receives it and transmits it to the control unit 250. At this time, the controller 250 reads the distance measurement signal and the position measurement signal to generate a subsea image, and if the generated submarine image is the same as the existing submarine image, deletes it, and if it is not the same, updates the existing submarine image to the new submarine image do.

On the other hand, when the lifting wire 231 of the lifting device 230 is broken by prolonged use or other external force, the underwater detector 100 is disconnected from the probe 210, and sinks.

At this time, as the underwater detector 100 sinks, the water pressure measured by the water pressure sensor 170 changes, and the water pressure signal according 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 a pressure signal indicating that the measured water pressure is out of the reference value, the control unit 180 opens the flotation device valve 124.

When the flotation device valve 124 is opened, the high pressure compressed gas is supplied to the buoyancy body 126 of the detector body 110 via the connection line L, and the buoyancy body 126 is caused by the expansion force of the compressed gas. ) Is inflated, the first opening and closing plate 113c is forced upward, and the first protrusion 113a of the first cover 113 is separated from the locking portion 112a of the buoyancy body mounting portion 112. It becomes as shown in FIG.

Subsequently, when the compressed gas is supplied to the buoyancy body 126, the buoyancy body 126 is further inflated as shown in FIG. 5, and the first cover 113 is buoyant body mounting part by the expansion force of the buoyancy body 126. 112)

Therefore, the buoyancy force acts on the buoyancy body 126, and the underwater detector 100 is floated to the water surface as shown in FIG. 6 by the buoyancy force. At this time, when the buoyancy body 126 swells to a certain degree, the control unit 180 closes the levitation device valve 124 so that the buoyancy body 126 does not swell anymore.

Accordingly, the lost underwater detector 100 can be easily found.

On the other hand, when the underwater detector 100 is raised to the surface as described above, the water pressure sensor 170 outputs a water pressure signal according to the position where the underwater detector 100 is supported, and the control unit 180 receiving the same, the marker The cylinder mechanism 161 of the device 160 is operated to move the piston 161b upwards and to operate the speaker 162.

As the piston 161b moves upward, the upper end of the piston 161b abuts on the second cover 115 of the detector body 110 as shown in FIG. 6, and the piston 161b continuously moves upward. The second cover 115 is moved upward. At this time, while the second protrusion 115a of the second cover 115 moves along the guide portion 114a of the marker device mounting portion 114, the second cover 115 moves upwards, and as shown in FIG. The through hole h2 of the second cover 115 is exposed to the outside. At this time, the second cover 115 is no longer moved while the second protrusion 115a is caught by the upper end of the guide portion 114a.

Accordingly, the notification sound of the speaker 162 is emitted to the outside through the through hole h2 of the second cover 115.

On the other hand, when the seabed topography check is completed, the underwater detector 100 should be moved to the probe 210.

At this time, when the worker drives the lifting device 230, the lifting wire 231 is wound around the underwater detector 100 is moved to the surface as shown in FIG. Thereafter, when the operator drives the driving device 220 to rotate the swinging structure 212, the underwater detector 100 is positioned above the probe 210 as shown in FIG. 9. Subsequently, when the operator operates the lifting device 230 to loosen the lifting wire 231, the underwater detector 100 is seated on the probe 210.

As described above, the terrain change confirmation and the seabed topography information update system of the sea channel according to the present invention, even if the underwater detector 100 is separated from the probe 210 can support the underwater detector 100 on the water surface The lost underwater detector 100 can be easily found, and in particular, the underwater detector 100 can be more easily found through the speaker 162.
