Multilayer stacking combined vertical type wind power generation system

Abstract

The invention discloses a multilayer stacking combined vertical type wind power generation system, which comprises multi-section combined crankshafts, multilayer stacking combined vertical type wind power systems and a multilayer stacking combined type frame, wherein each layer of wind power system has a box frame structure and comprises a fan blade system, a wind collection and protection system, a double-speed increasing device and a multi-winding electrode variation generator system; each layer of wind power system individually forms an independent wind power system for operation or all layers of wind power systems are fixed together by vertical posts at all corners; a detachable combined coupling is used for connecting all layers of fan blade crankshafts into a whole, so that synchronous turning moment can be generated by each layer of fan blades; and the lower shaft end of a fan blade crankshaft on the lowermost layer of the multilayer wind power system is connected with the double-speed increasing device and the multi-winding electrode variation generator system together through the detachable combined coupling. In the invention, the wind power generation system is decomposed into a plurality of layers of combined structures, is convenient to manufacture, transport, mount, assemble and maintain, has a small volume and high performance and can form a high-capacity power generation system.

Description

technical field [0001] The invention relates to a multi-layer stacked combined wind power generation system in the technical field of wind power generation. Specifically, it relates to a novel vertical wind power generation system with multiple layers of wind power machines superimposed and combined. Background technique [0002] With the occurrence of the world energy crisis, the use of wind kinetic energy as a new energy source has become a hot spot in the development of modern society. The generator set and speed increaser of the traditional three-blade wind turbine are installed at a height of 70 meters to 120 meters above the top of the tower, and the long and heavy wind blades are hung obliquely on the side, and a large counterweight is required. Considering that the wind blades, speed increaser, generator set, counterweight and the heavy engine room have a weight of hundreds of tons, which are supported at high altitude by the tower, the wind blowing will generate a ...

AI Technical Summary

Problems solved by technology

Considering that the wind blades, speed increaser, generator set, counterweight and the heavy engine room have a weight of hundreds of tons, which are supported at high altitude by the tower, the wind blowing will generate a huge overturning moment, and the wind blades It is difficult to resist the blowing of the strong wind and the damage of freezing damage. At present, there are many serious accidents at home and abroad, such as damage to the wind blades of the tower due to the storm, and damage to the wind blades due to freezing.

At the same time, traditional wind turbines are bulky, and transportation, assembly, and maintenance are extremely difficult; and there are defects such as small air volume received by the blades, low wind utilization rate, large wind starting torque, and large starting dead angle and commutation dead angle.

For example, the wind resistance of the front airfoil of the existing three-bladed wind turbine is large, the wind-receiving area of ​​the airfoil blade is small, the utilization rate of wind force is low, and the transportation, assembly and maintenance are difficult

[0003] After searching the literature of the prior art, it is found that the wind blades in the wind turbines recorded in the patent documents of Patent No. ZL200430067146.5 and Patent Publication No. W02007 / 140397A2 still have low wind power utilization rate, and there is a problem of start-up and rotation during start-up and rotation. The problem of large dead angle and reversing dead angle

[0004] Similarly, the fan blade system of the wind power generator involved in the invention patent of the patent application number 200410023530.4 adopts the NACA0009 airfoil. The wind blade has a small wind receiving area and a low wind utilization rate. There is a commutation dead angle, and it is difficult to increase the capacity
