Abstract

Раскрыто усовершенствованное подводное устройство (300а, б, в) выемки грунта. Известное устройство имеет ряд проблем, касающихся, например, коэффициента полезного действия и управления перемещением. Таким образом, в изобретении предложено подводное устройство (300а, б, в) выемки грунта, включающее в себя полый корпус (370а, б, в), имеющий, по меньшей мере, одно впускное отверстие (371а, б, в) и, по меньшей мере, одно выпускное отверстие (373а, б, в), по меньшей мере, одну пару лопастных колес (335а, б, в), (340а, б, в), смещенных вдоль общей оси одно относительно другого и установленных в полом корпусе (370а, б, в) с возможностью вращения, и средство привода лопастных колес, обеспечивающее их вращение в противоположных направлениях. Подводное устройство (300а, б, в) выемки грунта включает в себя два впускных отверстия (371а, б, в), направленные в противоположные стороны по горизонтали, которые сообщаются с одиночным выпускным отверстием (373а, б, в), и направляемое при работе вертикально вниз выпускное отверстие (373а, б, в), расположенное, по существу, на половине расстояния между двумя впускными отверстиями. Следовательно, устройство (300а, б, в) выемки грунта может, по существу, иметь Т-образную или Y-образную форму. Средство привода лопастных колес (335а, б, в), (340а, б, в) может включать в себя, по меньшей мере, один бурильный двигатель (310а, б, в).Международная заявка была опубликована вместе с отчетом о международном поиске.An improved underwater device (300a, b, c) excavation is disclosed. The known device has a number of problems relating to, for example, efficiency and motion control. Thus, the invention proposes an underwater device (300a, b, c) for excavating, comprising a hollow body (370a, b, c) having at least one inlet (371a, b, c) and at least one outlet (373a, b, c), at least one pair of impellers (335a, b, c), (340a, b, c), which are displaced along the common axis one relative to another and installed (370a, b, c) with the possibility of rotation, and the means of driving the blade wheels, ensuring their rotation in opposite directions. The underwater device (300a, b, c) of excavation includes two inlet openings (371а, б, в), directed in opposite directions along the horizontal, which communicate with a single outlet opening (373а, б, в), and directed during operation vertically down the outlet (373a, b, c), located essentially at half the distance between the two inlets. Therefore, the device (300a, b, c) excavation may, in essence, have a T-shaped or Y-shaped. The blade drive means (335a, b, c), (340a, b, c) may include at least one drill motor (310a, b, c). The international application has been published along with an international search report.
