MEASUREMENT SYSTEM OF VERY DEEP HYDROLOGICAL PARAMETRES Russian patent published in 2011 - IPC G01W1/00 

FIELD: mining.

SUBSTANCE: system consists of detachable depthsonde installed at carrying waterborne means, received information processing equipment and communication channel for data transmitting from the detachable sonde. The detachable depthsonde can be thrown off from the device. The device comprises the case with inner cylindrical surface pressure-tight installed in the housing of carrying waterborne means. In the said case there is rigidly fixed guiding sleeve that serves for sequential installation of detachable depthsonde in it, onboard communication channel coil with pusher and reference measuring devices. Reference measuring devices are connected to received information processing equipment by communication channel. Note that communication channel for transmitting measurement data from the detachable depthsonde connects the sonde to reference measuring devices or directly to received information processing equipment. At that, the case of the device has, at least, one hole for the supply of outside water that provides detachable sonde sensors calibration, for air removal from the device at its water filling, for water supply with the aim of creation of over pressure that provides the breaking of detachable depthsonde communication channel and removal of onboard coil with pusher, for air supply aiming to dry the device and water discharge at drainage. The end holes of device casing are closed by inner and outer sealed covers controlled by drives.

EFFECT: increase of measurement accuracy, simplification of structure that is lost at throwing out of detachable depthsonde part.
