Embodiment Construction

[0024] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0025] to combine Figure 1-8 , four sets of wind turbine support rods 8 of the present invention are connected together by bolts to form a wind rotor, the wind rotor rotates around the rotating main shaft 10 of the vertical axis wind power generator, and the blades 7 are installed on the wind rotor support rods 8 through the bearing seats 16 and 17 at both ends . Both the wind direction sensor 18 and the rotational angle position encoder 9 are installed on the top of the rotating main shaft 10; the active stall control structure is installed at the lower end of the wind wheel. The drive generated by the servo motor 15 outputs 4 identical motions through the power distribution plate 11, and the motion output by the power distribution plate 11 is transmitted to the driving wheel 14 by two sets of belts through the intermediate pulley 13 to realize real-time contro...

Abstract

The invention aims to provide a floating type marine wind energy and wave energy hybrid power generation platform which comprises a vertical shaft wind driven generator, an oscillating type wave power generating device and a floating body, wherein the vertical shaft wind driven generator and the oscillating type wave power generating device are respectively arranged on the floating body; the oscillating type wave power generating device comprises a floater, an oscillating rod and a wave power generator; the floater is connected with the oscillating rod, and the oscillating rod is connected with the wave power generator through a wave motion reversing device; and the wave power generator is connected with an energy storage device through a power conversion device. According to the floating type marine wind energy and wave energy hybrid power generation platform, the application range of the hybrid power generation platform is expanded, the stability and the safety performance of the power generation platform are improved, the construction cost and the maintenance cost are reduced, and the power generation efficiency is improved by active stall control and phase change control, so that the floating type marine wind energy and wave energy hybrid power generation platform is a reliable offshore power generation platform.

Description

technical field [0001] The invention relates to a power generating device, specifically a wind energy and wave energy generating device. Background technique [0002] The ocean contains huge renewable energy, among which wave energy is one of the most abundant energy sources; at the same time, ocean wind energy is more abundant and of better quality than land, and the development of ocean energy has become a strategic choice for countries all over the world. my country's coastal cities are industrially developed, densely populated, and power resources are in short supply. The problem of island military and civilian power consumption is even more prominent. However, my country has a long coastline and rich marine resources. Increasing the development of marine wind energy and wave energy can effectively alleviate the problem of power resources in coastal cities and islands. [0003] Since wind energy is continuous within the available range, while waves are periodic, the gen...
