Underwater vehicle with pumping set for propelling

Abstract

The invention relates to an underwater vehicle with a pumping set for propelling. The problems that an underwater vehicle is poor in self-suction capacity and can not meet the demand for hydrodynamic performance are solved. According to the technical scheme, a front jet orifice assembly and a rear jet orifice assembly are arranged at the front end and the rear end of a shell correspondingly; the shell is provided with a water inlet and a jet orifice used for controlling the traveling direction of the shell; the water inlet is connected with a water inlet of a centrifugal pump; a water outlet of the centrifugal pump is connected with a water inlet of a high pressure plunger pump; a water outlet of the high pressure plunger pump is connected with the front jet orifice assembly, the rear jet orifice assembly and the jet orifice to form a control structure for the traveling direction of the shell; a water inlet of a water storage tank is connected with a water outlet of a bidirectional gear pump; a water outlet of the bidirectional gear pump is connected with a water changing opening formed in the shell; and a buoyancy type vertical position adjusting structure for the shell is formed. The underwater vehicle with the pumping set for propelling guarantees the suction force of the high pressure plunger pump, effectively improves the efficiency of the high pressure plunger pump, improves the propelling efficiency, and is convenient to use and good in effect.

Description

technical field [0001] The invention relates to an underwater vehicle, in particular to a pump group propelled underwater vehicle. Background technique [0002] At present, most underwater vehicles using a water jet propulsion system generally use water as a medium, obtain a higher speed through a high-pressure plunger pump, and spray it out from a nozzle to generate propulsion. Due to the poor self-priming ability of the plunger pump in this propulsion system, it is difficult to ensure a strong water flow from the injection port, and it is difficult to meet the hydrodynamic performance of the underwater vehicle, so that it cannot generate enough propulsion to drive the navigation of the vehicle. [0003] Therefore, there are inherent deficiencies in existing water-jet propulsion systems, and it is urgent to develop a new water-jet propulsion scheme for underwater vehicles.
