Water tank type floating breakwater equipped with power generation device

Abstract

The invention discloses a water tank type floating breakwater equipped with a power generation device. The water tank type floating breakwater comprises a water tank, wherein the water tank is dividedinto an upper layer tank body and a lower layer tank body through a partition plate, and the upper layer tank body is filled with water. A swing plate rotating shaft is rotatably arranged in the partition plate. The end portions of the swing plate rotating shaft penetrate through the water tank. The end portions, extending out of the water tank, of the swing plate rotating shaft are provided withgears I correspondingly. A swing plate is rotatably installed on the swing plate rotating shaft. One end of the swing plate extends into the upper layer tank body, the other end of the swing plate extends into the lower layer tank body, and the end portion, extending into the lower layer tank body, of the swing plate is provided with a mass block. The lower portion of the partition plate is provided with an elastic beam, and the elastic beam is provided with a piezoelectric film in a covering mode. The lower layer tank body is provided with an electromagnetic power generation device. The endportions of a generator input shaft of the electromagnetic power generation device penetrate through the water tank. The end portions, extending out of the water tank, of the generator input shaft areprovided with gears II correspondingly. The gears II are meshed with the gears I. By means of the water tank type floating breakwater, external wave energy can be effectively absorbed and eliminated,and sloshing wave energy in the water tank can be converted into electric energy required for production.

Description

technical field [0001] The invention relates to the technical field of breakwaters, in particular to a water tank type floating breakwater equipped with a power generation device. Background technique [0002] Breakwater is a more commonly used offshore wave-proof structure, which is used to absorb wave energy, block wave impact, and protect the harbor basin to keep its water surface stable to protect the port terminal from bad weather. Among them, the floating breakwater is widely used because it is not limited by the water depth, is conducive to seawater exchange, and has high economic efficiency, especially the deep water sea breakwater. However, the floating breakwater moored to the seabed by anchor chains has the disadvantage of excessive movement range under the impact of waves, which affects the normal use of the breakwater. [0003] The development of renewable energy is a research hotspot in the world today as the development of fossil energy is exhausted day by da...
