Abstract

The invention discloses an amphibious screw propulsion device. The device comprises a driving part, at least two spiral propulsion buoys, a first carrier and a second carrier, one end of each spiral propulsion buoy is rotationally connected with the first carrier, and the other end of each spiral propulsion buoy is rotationally connected with the second carrier; the driving part is arranged on thefirst carrier or the second carrier and is connected with the spiral propulsion buoys; and the driving part is used for driving the spiral propulsion buoys to rotate so as to provide power required by ship movement. According to the invention, a ship can freely sail in an area with shallow water or unknown water depth, and the working efficiency of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an amphibious screw propulsion device and a using method. Background technique [0002] When a ship sails in shallow water, the following unfavorable phenomena usually occur: the speed of the ship decreases, the hull sinks, the trim changes, the rudder effect deteriorates, and the bow deflects to the deep water side, and the inland river that is too shallow may even lead to grounding. The existing mainstream ship propulsion devices mainly include propeller propulsion devices, water jet power propulsion devices and air cushion fan propulsion devices. [0003] The principle of the propeller propulsion device is to use the power output by the engine to drive the blades to rotate through the transmission shaft. The rotation of the blades increases the kinetic energy of the fluid, and then obtains the thrust required for the movement of the ship. The propeller propulsion device has bec...
