In the structure of the conventional submarine cable type crustal observation apparatus, that is, the structure shown in FIG. 3, since the pressure-resistant housing is cylindrical, the submarine cable axis depends on the geological condition of the seabed or the submarine flow. And the coupling with the seabed is not always good. Further, in the structure shown in FIG. 4, the structure of the coupling cage is large-scale and does not have a balance function of absorbing irregularities on the sea bottom, so that the static balance may be broken under a hard sea floor. Possible long-term crustal observation problems.

[0007] The cylindrical pressure-resistant container 1 accommodating the internal unit 8 composed of a sensor and a circuit section has one end side through the joint ring 4 and the clamp rings 5, 6, 7.
The pair of submarine cables 2 are connected to two stay fittings 3 which are retained in a forked manner. The submarine cable 2 is connected to the internal unit 8 via the cable 11. On the other hand, on the other end of the pressure-resistant housing 1 to which the submarine cable 2 is not connected, a coupling component 15 (the gimbal 14 and the anchor 13 shown in FIG. 2 in this description) between the seabed and the pressure-resistant housing 1 is attached.

According to the configuration of the present embodiment, the retaining fittings 3 necessary for signal transmission and power supply can be arranged in a bifurcated manner on one side, so that there is an effect of suppressing the rotational movement of the pressure-resistant housing 1 and the state of submarine installation. Depending on the situation, the effect of avoiding the suspension of the pressure-resistant housing 1 on the seabed due to the inquiry of the seafloor cable 2 from both sides can be expected. Further, it is expected that the pressure-resistant housing 1 can be relatively installed along the seafloor topography and seafloor geology with the function of the universal joint together with the gimbaled anchor provided at the other end. Further, the coupling component 15 only has to be mounted on the mounting plate at the end, and there is an advantage that various shapes can be easily selected.

As described above, according to the present invention, the submarine cable is provided on only one side of the pressure-resistant housing.
The other end can be used for mounting parts for improving the coupling performance between the housing and the seabed, and if an anchor with a gimbal as shown is used as a coupling part, it functions in a well-balanced manner with the cable end fittings to provide a pressure-resistant housing. Rotational movement can be suppressed, and a great effect can be expected as a submarine cable type crustal observation structure that requires long-term precision observation.
