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

[0025] The present invention is mainly realized by the following methods. Such as figure 1 As shown, the present invention provides a multi-layer and multi-pillar combined vertical-axis wind power generation system that can avoid strong winds, including a tower column 4, a load-bearing platform 3 is provided in the tower column 4, and a vertical-axis wind power system is set on each load-bearing platform Power generation unit 5.

[0026] Such as Figure 5 , 6 , 7, 8a, 8b, 8c, the tower column 4 supporting the entire wind tower can be set up with 2, 3, 4 or more, and can be arranged in various ways; Figure 5 , 6 7. As shown in 7, the main cantilever fixed hub and the main shaft 21 can be arranged in the center of multiple tower columns, or Figure 8a , 8b , 8c and set at the eccentric position of multiple tower columns as needed; 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 equipped with a...

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 use wind energy, reduce investment costs, and effectively avoid damage to the system caused by the harsh strong wind environment. 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] The existing vertical axis wind power generation system is mostly a single-layer wind-absorbing structure supported by a single tower column. A lot of construction costs are invested to bring the wind rack to a suitable working height. However, the wind-absorbing power generation mechanism only has one layer, which not only causes The huge investment waste also limits the improvement of th...
