[0004] However, the structure of the horizontal axis wind turbine is relatively complex, the size of the rotating wind rotor is large, and the generator set is placed on the top of the tower, resulting in a large overturning moment of the unit. The cost is high, and the performance improvement is close to the limit, which seriously restricts the sustainable development of wind power on board

Embodiment Construction
[0013] like figure 1 As shown, the marine wind power generation system of the present invention includes a vibrator 1 , a damping plate group 2 , an elastic support structure 3 , a piezoelectric material module 4 , a synthetic fiber rope 7 and a spring damping stabilizer 8 .
[0014] The working mode of the system of the present invention is: the air flow of the external environment acts on the frustum-shaped, rigid hollow vibrator. According to the principle of aerodynamics, the air flow will be separated on the wall surface and form a periodic shedding vortex in the wake. Street, the vibrator will also produce periodic vibration; the damping sheet group is fixed on the inner wall of the vibrator, which is a matrix composed of sixteen block damping sheets, which are divided into four columns in the horizontal direction and spaced at 90° azimuth angle Evenly arranged on the inner wall of the vibrator, arranged in four equidistant layers in the vertical direction, its function ...

The invention relates to a marine wind power generation system. The invention provides a marine wind power generation system aiming at the solid shortage of the current wind power generator, which ischaracterized in that the system comprises a vibrator and a damping plate group; The vibrator is a rigid hollow shell in the shape of a circular table, and a damping plate group is fixed on the innerwall surface; The damping fin group is a matrix composed of sixteen block damping fins, which are divided into four columns in horizontal direction, uniformly arranged on the inner wall surface of thevibrator according to 90-degree azimuth angle interval, and arranged in four equal spacing layers in vertical direction. Compared with current wind turbines and other novel wind power generation systems, the marine wind power generation system of the present invention has high utilization avoidance efficiency, is simple to implement and is suitable for use on ships.
Description
technical field [0001] The invention relates to a marine wind power generation system. Background technique [0002] Ships are generally equipped with solar power generation systems, but they are greatly affected by the sun. For example, when it is cloudy or rainy, solar power cannot provide electricity. [0003] Wind power is a clean renewable energy with huge reserves and will occupy an important position in the future world energy pattern. At present, large-scale horizontal axis wind turbines are widely accepted commercially and are becoming more and more perfect. Its working principle is: the airflow acts on the wind wheel, generating aerodynamic load to drive the wind wheel to rotate, and driving the generator to generate current. [0004] However, the structure of the horizontal axis wind turbine is relatively complex, the size of the rotating wind rotor is large, and the generator set is placed on the top of the tower, resulting in a large overturning moment of the u...
