SELF-PROPELLED VEHICLE FOR GATHERING CONCRETIONS IN CONDITIONS OF A BOTTOM OF THE WORLD OCEAN Russian patent published in 2004 - IPC

FIELD: mineral product mining on the world ocean bottom .

SUBSTANCE: the invention pertinent to installations for production of mineral resources from a bottom of seas and oceans, in particular to a self-propelled vehicle, that may be used for gathering of concretions in conditions of a bottom of the world ocean The self-propelled vehicle contains: an actuating mechanism made in the form of a drum - ripper with chisels and the built-in drive made in the form of a straight-flow multiple-stage hydroturbine; a tip - a nozzle of a hydro-lifting string and a crawler; a mounted on a crawler additional drive with an electrical cable made in the form of an asynchronous motor in a waterproof version and rigidly linked with an adjustable oil pump with the spring pressure gage; a quantity distributor at the output of the oil pump; control valves to reverse a course of the crawler and turning displacement of the crawler tracks. The control valve to reverse the course is linked to volumetric hydromotors through the quantity distributor and the control valves of left-hand and a right-hand turning of the crawler tracks. The oil pump of the drive has directly proportional dependence of its pressure from distribution. The invention allows to improve reliability operations. At that it forms conditions of operational stability of the whole installation) at the expense of maintenance of equal stability of characteristics of the drives of the crawler and the hydroturbine.

EFFECT: improved reliability and stability of operations of the self-propelled vehicle and its components.
