Problems solved by technology

[0002] Most of the existing vertical axis wind power generation systems are single-layer wind-intake structures supported by a single tower. It takes a lot of construction costs to mount the wind turbines to a suitable working height. The huge waste of investment also limits the improvement of the power generation capacity of the system, and there is no good solution to how to avoid the wind damage caused by the strong wind environment to the system, which limits the many advantages of the vertical axis wind power generation system.

Embodiment Construction

[0028] The present invention is mainly realized by the following methods.

[0029] There can be 2, 3, 4 or more tower columns 4 supporting the wind tower. The main cantilever fixed hub and the main shaft 21 can be arranged at the centers of multiple tower columns, or at the eccentricity of multiple tower columns as required. Position; the support points of each tower column 4 are set outside the radius of rotation of the main wind wing 11, and each tower column 4 can be provided with a reinforcement stay or a pillar 2 to enhance system stability.

[0030] Single-layer, double-layer, three-layer or even multi-layer load-bearing platforms 3 can be installed at different heights of multiple tower columns, and one, two, three or even multiple vertical-axis wind power generation units 5 can be installed on each load-bearing platform 3 , the rotation direction of each vertical axis wind power generation unit 5 can be the same, and can also alternately rotate in reverse to offset or ...

Abstract

The invention relates to a multilayer multi-column combined type vertical shaft wind power generating system which can effectively prevent a rugged strong wind environment from damaging a system, effectively utilizes wind power and runs more safely and stably. A multilayer combined type structure comprising a plurality of tower columns and a plurality of generating units is arranged; the wind power is utilized to directly drive main wind wings of the generating units of the vertical shaft wind power, and a main cantilever, a main cantilever fixed hub and a main shaft are utilized to drive a generator to generate electric power; whereas, when the rugged strong wind environment comes, the front face area of the main wind wing is regulated so as to effectively prevent the strong wind from damaging the system; a strong wind early warning system is arranged, when that the strong wind attacks is detected, the strong wind early warning system can send an instruction to the system in advance so as to take a strong wind avoiding measure, thereby greatly improving the running state, the safety and the stability of the wind power generating system.

Description

technical field [0001] The invention relates to a multi-layer and multi-column combined vertical-axis wind power generation system capable of avoiding strong winds, which is used in the technical field of efficiently utilizing wind energy to obtain clean energy. It can efficiently utilize wind energy, reduce investment costs, and effectively avoid damage to the system caused by harsh strong wind environments. Greatly improve the efficiency of wind energy utilization, reduce investment and construction costs, and improve the safety and stability of system operation. Background technique [0002] Most of the existing vertical axis wind power generation systems are single-layer wind-intake structures supported by a single tower. It takes a lot of construction costs to mount the wind turbines to a suitable working height. The huge waste of investment also limits the improvement of the system's power generation capacity, and there is no good solution to how to avoid the wind dam...
