In detail, the temperature measurement unit m3 may be provided on the lower surface of the housing 100 to immediately detect high-temperature seawater due to the submarine earthquake. However, the position of the temperature measuring unit m3 is not limited to this, and may be provided at various positions such as an outer surface of the housing 100. In addition, the control module (c) located on the float includes a reference frequency and a reference frequency stored in advance.

When the housing 100 is located in the water, the vibration measuring unit m2 measures the frequency of the housing 100 and transmits information on the measured frequency to the control module c. The control module (c) receives the frequency from the vibration measurement unit (m2), and compares it with a reference frequency stored in advance.

When the measured frequency is greater than the reference frequency, since the housing 100 is excessively shaken as the flow rate increases as it goes up from the water to the surface of the water, the control module (c) winds down the signal that pulls out the cable (a). Send to wealth. The winding unit receives the descending signal and releases the cable (a), so that the housing 100 descends by a predetermined height in the downward direction. In the water, since the flow rate is smaller and the flow rate change is smaller as the depth goes toward the depth, the frequency of the housing 100 moving in the downward direction gradually decreases. After the housing 100 descends by a predetermined height in the downward direction, the temperature measuring unit m3 measures the temperature around the housing 100 and transmits it to the control module c. The control module (c) compares the received temperature with a reference temperature. Here, when the measured temperature is greater than the reference temperature, it means that the high temperature seawater erupted from the underwater earthquake or submarine volcanic eruption in water, or the torpedoes located in the water are detonated. The rising signal for winding a) is transmitted to the winding unit, and the winding unit that receives the cable winds the cable (a) to raise the housing 100 by a predetermined height in the upward direction. If the measured temperature is less than or equal to the reference temperature, the control module c does not transmit a separate signal to the winding unit, and accordingly, the housing 100 continuously maintains the height from the water surface.

In addition, when the measured frequency is less than or equal to the reference frequency, the housing 100 is not excessively shaken. As a result, the control module c does not transmit a separate signal to the winding part, so that the housing 100 is removed from the water surface. Will maintain the height of Thereafter, the temperature measuring unit m3 measures the ambient temperature of the housing 100 and transmits it to the control module c, and the control module c compares the received temperature with the reference temperature. Here, when the measured temperature is greater than the reference temperature, it means that the high temperature seawater erupted from the underwater earthquake or submarine volcanic eruption in water, or the torpedoes located in the water are detonated. The rising signal for winding a) is transmitted to the winding unit, and the winding unit that receives the cable winds the cable (a) to raise the housing 100 by a predetermined height in the upward direction. If the measured temperature is less than or equal to the reference temperature, the control module c does not transmit a separate signal to the winding unit, and accordingly, the housing 100 continuously maintains the height from the water surface.

Through the series of processes described above, if the housing 100 is excessively shaken, it can be immediately detected to reduce the frequency of the housing 100, and if the temperature around the housing 100 is excessively high, the housing is immediately responded to it Since the 100 can be separated from the high temperature seawater, it is possible to prevent the housing 100 from being damaged. In addition, it is possible to immediately detect the submarine earthquake, submarine volcano or mine detonation, so it can be useful for geological surveys and military reconnaissance.

Additionally, when the object o is to be photographed from multiple angles, a desired object o may be photographed by photographing the object o while changing the inclination of the housing 100.

To this end, the interior of the housing 100 is divided into an upper space portion e1 and a lower space portion e2. In detail, the interior of the housing 100 is divided into an upper space portion e1 and a lower space portion e2 through a first partition portion 160 formed in a horizontal direction. In the lower space portion e2, the above-described imaging portion, light irradiation portion, vibration measurement portion m2, and temperature measurement portion m3 are located, and the upper space portion e1 is provided with a fluid stored in advance. As a more preferred embodiment, the fluid in the upper space portion e1 is provided with air, an inert gas such as helium or neon, and a liquid such as distilled water may be further provided. In addition, as the upper space part e1 is divided into the first upper space part e11 and the second upper space part e12 through the second partition part 170 formed in the vertical direction, the first upper space part e1 e11) and the second upper space portion e12 are provided with a fluid divided.
