Electric propulsion Yangtze River vehicle passenger ferry longitudinal streamline

Abstract

The invention discloses an electric propulsion Yangtze River vehicle passenger ferry longitudinal streamline. The streamline comprises a supporting frame, propeller mounting supporting frames are fixedly mounted on both sides of the interior of the supporting frame, circular protective covers are fixedly mounted at the bottom ends of the two propeller mounting supporting frames, the interiors of the protective covers are provided with connecting rods in a crossed mode, bearings are fixedly embedded at the intersections between the connecting rods, the surfaces of the bearings are provided withpropulsion impellers in an inserted mode, the rotating diameters of the propulsion impellers are less than the diameters of the protective covers, the backs of the propulsion impellers are connectedwith impeller propulsion mechanisms, impeller propulsion mechanisms comprise gear rotating speed boxes and ship driving motors, and the gear rotating speed boxes are internally connected with worm wheels and worms which are in meshing. According to the electric propulsion Yangtze River vehicle passenger ferry longitudinal streamline, a water inlet cover and a water inlet groove arranged, so that external water can be conveniently injected, and the propulsion impellers are arranged, so that the water is subjected to eddy current pressurizing suction and is sprayed out in the rotating process asa jet.

Description

technical field [0001] The invention relates to a longitudinal flow profile, in particular to a longitudinal flow profile of an electric-propelled Yangtze River car-passenger ferry. Background technique [0002] Ferries have the following characteristics: [0003] One is that the hull structure is simple, and the equipment on board is simple, especially the ferry used for transition in rivers, the hull is light and light, and there are few living facilities. [0004] The second is that there are large cabins and decks, which are convenient for carrying more passengers and more cargo. [0005] The third is good maneuverability. Generally, there are two sets of power devices, which are propelled by double propellers. The maneuverability is good. It can easily dock at the dock, get on and off passengers, and load and unload goods. [0006] Fourth, it has good stability, the hull is wide and stable, and some ferries adopt the catamaran ship type, which is stable when sailing; ...
