る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a sectional view showing an embodiment in which the attitude control mechanism of the present invention is applied to a transducer of an underwater acoustic device installed on the bottom of a ship, and FIG. 2 is a top view of the same. As shown in FIGS. 1 and 2, the present attitude control mechanism includes a ring-shaped flange 1 holding a spherical body 2 having a concave inner surface, a ball screw 3 for transmitting a force generated by a motor 4, and a ball. A universal joint 5 that supports one end of the screw 3 and is connected to the flange 1, a packing 6 for preventing water leakage provided between the flange 1 and the sphere 2, and a transducer 8 that needs to be kept horizontal by turning and holding And a rotating motor 9 for rotating the rotating shaft 7 and a shaft 10 for supporting the motor 4.

波器８も水平に姿勢制御される。Next, the operation will be described. The attitude control mechanism attached to the ship bottom 11 tilts when the ship tilts in an arbitrary direction, and the transducer 8 that needs to be kept horizontal also tilts. Therefore, the motor 4 held by the shaft 10 is operated for correction corresponding to the amount of inclination. Since one end of the ball screw 3 is connected to the flange 1 via the universal joint 5, the fulcrum distance of the ball screw 3 is changed by the correction operation of the motor 4, and as a result, the sphere 2 connected to the flange 1 moves. As a result, the spherical body 2 is kept horizontal, and the transducer 8 connected to the spherical body 2 via the turning shaft 7 is also horizontally attitude-controlled.

いる。FIG. 3 is a partial cross-sectional view showing a mounted state of the attitude control mechanism. In the figure, an attitude control mechanism 13 is attached to a ship bottom 11, and a transducer 8 to be subjected to attitude control.
Is located in fresh or sea water. The rectifying cover 12 is attached for the purpose of protecting the transducer 8 when the ship is navigating and reducing the resistance of waves. further,
In order to make it possible to use the transducer 8 in fresh water or seawater and in a state where water pressure is applied, the attitude control mechanism 13 is used.
A seal material is used for a joint portion for attaching the fin to the ship bottom 11, and in particular, leakage from a gap between the sphere 2 and the flange 1 is dealt with by using a packing 6 having a small frictional resistance.
