Problems solved by technology

[0003] Focusing on the goal of reducing the cost of wind power generation and improving the performance of wind turbines, domestic and foreign scholars have carried out a series of fruitful research work, and proposed many new principles and new configurations of large-scale wind power generation systems. Typical schemes include: drag vertical axis wind turbine , Darrieus vertical axis wind turbines, Magnus effect wind turbines, double or multiple wind turbines, wind / solar integrated wind turbines, etc. There are also many crossover and extension designs, However, these wind turbine systems still retain the traditional rotating wind wheel, which makes it difficult to greatly improve the efficiency of wind turbines, and cannot fundamentally overcome the impact on the environment and organisms
For wind power generation systems without wind turbines, the University of Delft in the Netherlands proposed grid wind turbines, which rely on electrostatic conversion technology. When positively charged particles in the wind pass through the grid wires, currents will be generated. small, very inefficient
U.S. Patent "Wind turbine for generation of electric power" U.S. Patent No.: US7695242 hides the rotating wind wheel. By setting up multi-layer independent disks with many small wings, the airflow pushes the disks to rotate to drive the generator to generate electricity, but Considering the boundary layer effect of the fluid, the efficiency of air flow through such a complex structure is low

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the structure of the vibration power generation system provided by the present invention is composed of a vibration generator 1, a damping sheet group 2, an elastic support structure 3, a piezoelectric material module 4, a synthetic fiber rope 7 and a spring damping stabilizer 8.

[0025] According to the aerodynamic principle of the action of the airflow on the cylinder, the vibration generator 1 generates periodic vibration, and the damping sheet group 2 is used to effectively control the vibration, so that the piezoelectric material module 4 deforms and moves, and the piezoelectric material of the material The effect generates current, which is then transmitted to the grid or energy storage equipment through the converter. At the same time, in order to ensure the safety of the system under extreme conditions, a safety protection ...

Abstract

The invention relates to a vibration-type wind power generation system. A conventional rotating wind turbine generator is not friendly to biology and environment, gets close to the limit of wind power utilization rate, is complex in structure, and is high in manufacture and maintenance cost. The system consists of a vibration generator, a damping fin group, an elastic supporting structure body, a piezoelectric material module, a synthetic fiber rope, and a spring damping stabilizer. The system is characterized in that the vibration generator is a hollow housing; the damping fin group is fixed on an inner wall surface of the vibration generator; the elastic supporting structure body is located below the vibration generator, and is used for supporting the vibration generator; the piezoelectric material module fastens and wraps the outer wall surface of the elastic supporting structure body; the upper end of the synthetic fiber rope is fixed on the vibration generator, and the lower end of the synthetic fiber rope is connected with the spring damping stabilizer; moreover, there is a certain length allowance. The system prevents a rotating wind turbine from affecting the biology and environment, is high in wind power utilization rate, is simple in implementation, and is suitable to be used in a populated region.

Description

technical field [0001] The invention relates to a vibration-type wind power generation system, which belongs to the field of design and application of wind power generators. Background technique [0002] 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. 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. With the development of large-scale units, the requirements for the nacelle, tower and yaw mechanism are also increa...
