As a further preferred aspect of the present invention, the container end face is provided with a GPS placement box.

Compared with the prior art, the utility model discloses the beneficial effect who has as follows:

1. the influence of ADCP installation environment and rivers has been eliminated, simple structure, and the operation is stable, long service life, and the maintenance installation is simple, and is with low costs, and the recovery of instrument is more accurate, simple.

2. The ADCP3 and the ADCP outer ring are subjected to vertical upward buoyancy and vertical downward gravity, the buoyancy is larger than the gravity, the ADCP rises, and the ADCP is positioned on the same horizontal plane due to the lower three ropes, so that the stable state of the ADCP is ensured.

3. The underwater equipment remote control device sends out instructions by a hydroacoustic method and remotely controls or recovers underwater equipment. Is tied on an underwater buoy or a seabed sinking object. When the device is used, a 'release command' (coded signal) is transmitted by an acoustic commander on a ship, the release starts the hook member to be separated from the anchoring equipment after receiving the command, and at the moment, instruments or devices submerged under the water automatically float up to achieve the purpose of control or recovery.
