Description of the Related Art Conventionally, this type of hydrophone is provided with a vibration-receiving element for sensing underwater-borne sound and the like placed in a cylindrical rubber film, immersed in insulating oil around the periphery, and subjected to a water pressure treatment. Things. The receiving wave element of this hydrophone uses a flexural vibrator in which a piezoelectric plate is adhered to a vibration plate, and the two receiving wave elements are arranged near both end surfaces of a cylinder. Therefore, the vibration receiving sensitivity of this hydrophone is high at both end surfaces of the cylinder and decreases at the center of the side trunk.
When observing the seafloor propagation sound, this hydrophone is dropped into the sea and rolled to the seabed. Also, an underwater cable for transmitting observation data to an observation station on the sea or on the land is attached from the side body of the hydrophone.

Unit is configured. A ring 5 made of titanium is provided at the center of the body side of the hydrophone main body 1, and a grip portion 3 and a fixing bar 2 are respectively mounted on screw holes of a mounting seat 6 provided on the upper and lower outer periphery of the ring 5. I have. Since the grip portion 3 and the fixing bar 2 can be easily removed and attached, it is easy to transport by removing them when transporting. Further, since the underwater cable 4 is inserted through the hollow portion of the grip 3, the underwater cable 4 is not obstructed when the manipulator grips the grip 3.
