Boardside planking piezoelectric power generation device utilizing ship rolling

Abstract

The invention provides a broadside planking piezoelectric power generation device utilizing ship rolling. The device comprises a fixed hinge support, an elastic material, a pressing plate, a cushion block, a piezoelectric material and a reset spring. According to the device, at the beginning of ship design, a piezoelectric material is embedded into a broadside outer plate of a freeboard part of a ship body, when rolling motion occurs in the ship navigation process, water pressure is used for extruding the piezoelectric material to generate power, generated electric energy is processed and then merged into a ship power grid to supply power to ship power equipment, and energy conservation and emission reduction of the ship are achieved. Besides, due to the fact that the length of the freeboard part above the waterline of the ship in the length direction of the ship is very long, a large number of the device can be arranged in a freeboard groove, when the ship performs rolling motion, the area of the freeboard part immersed in seawater is very large, and the pressure of the seawater on a board side outer plate of the freeboard part is very large. According to the invention, the recoverable energy is very huge, and the power generation effect is good.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a piezoelectric power generation device for side shell plates utilizing ship rolling. Background technique [0002] At present, the number of ships is gradually increasing. These ships need to burn fuel oil to provide power for navigation during the navigation process. The carbon dioxide and other exhaust gases emitted by burning fuel oil have aggravated the pollution to the environment. Therefore, reducing energy consumption and finding new energy sources has become an urgent problem to be solved in the shipbuilding industry. Some scholars have begun to study the application of renewable energy such as solar energy and wind energy on sailing ships, and have designed energy recovery devices, which have achieved certain application effects. As a renewable energy with abundant reserves in the ocean, wave energy has unique advantages in its application on sailing ships. ...

Problems solved by technology

Although this patent realizes the recycling of wind energy and wave energy, the way of energy recovery on the external cantilever beam along the ship will cause serious surface irregularities of the hull, making the hull uneven and destroying the original streamlined shape of the hull. When the ship rolls during navigation, the cantilever beam at the lower end of the ship will increase the contact area between the hull and the water surface, so that the ship equipped with this device will generate very large additional resistance when sailing, resulting in insufficient energy generated by the power generation device. To make up for the energy consumed by the ship due to additional resistance, the gain outweighs the gain, so this patent has no implementation value and innovation
