A ship floating on the sea, and the electric winding device 2 of the ship 1
At the end of the cable 3 is a disk-shaped and tail
A balloon 4 having A is connected and supported in a three-point support type. An imaging device 5 provided on a two-axis drive base is provided on the lower surface 4a of the balloon 4. Image information captured by the imaging device 5 is transmitted wirelessly by a device for transmitting an image or a signal in the cable 3 is transmitted. The signal is transmitted to a receiver in the ship 1 or a receiver at a land base via a line. Note that this imaging device 5
Is provided with a well-known flux valve (magnetic azimuth sensor), which is configured to detect the azimuth of the imaging device 5 at sea and display the detected azimuth on an image.

It is held inclined in the front-rear direction by the mounting angle θ by the cable 3, and the state of the sea can be imaged by the imaging device 5 according to the movement of the ship 1. For example, the presence of fish is monitored by the state of seabirds on the sea. You can also.

Since A is always leeward, the balloon 4 is always at the angle of attack α.
Occurs. In this case, as shown in FIG. 3, L 1 =
Buoyancy of the balloon, L 2 = 1/2 ρ · V 2 · S · C L , D =
1/2 ρ · V 2 · S · C D (ρ is air density, S is area, C
L is a lift coefficient, C D is a drag coefficient, and V is speed), C L is about 1.0 to 1.5, and the balloon 4 has L
= L 1 + L 2 lift is generated. On the other hand, C D is because of the order of 0.1 to 0.2 unchanged almost, L is sufficiently larger than D, V is not being washed away large to leeward also increased. The shape of the balloon 4 can be other than a disk.
