Abstract

The invention relates to a rectilinear propulsion ship which comprises a ship body, wherein at least one group of rectilinear paddle driving device is arranged on the ship body; and in the rectilinear paddle driving device, at least two transmission wheels are connected through a rectilinear paddle belt, and a plurality of paddles are arranged on the rectilinear paddle belt. According to the rectilinear propulsion ship provided by the invention, a traditional propeller rotation water pushing way is changed to a rectilinear paddle type propulsion way, water-pushing speed and turbulent flow interference are reduced, the area of a propulsion device, which is in contact with water is expanded, and propulsion performance and energy conservation efficiency can be improved; furthermore, energy efficiency under various rotational speed and cruising speed conditions can be kept unchanged, large-scale energy conservation can be realized on the whole and endurance capability of an electric ship can be greatly improved.

Description

technical field [0001] The invention relates to an improved ship, in particular to a linear propulsion ship suitable for electric ships. Background technique [0002] Traditional ships are propelled by propellers. Since the propeller is converted into the power of linear motion that propels the ship forward and backward by rotating and pushing water, it will inevitably cause a large energy loss. At the same time, because the propeller rotates at a high speed (100-500 rpm), the water flow pushed out by the propeller rotation The greater the speed, the greater the energy wasted, and due to the action of centrifugal force, more water flow is thrown out along the radial direction of the propeller, so the overall energy conversion efficiency is low, all due to the small interaction area between the propeller and water, the effect The reason for the short time. In addition, the highest efficiency of the propeller appears at the highest speed of the ship, and the supporting desig...
