Lifting composite dual-form wind energy power generation device

Abstract

The invention provides a lifting composite dual-form wind energy power generation device, and relates to the technical field of vertical-axis wind energy power generation equipment. The shaft body ofa central rotary shaft is of a crossed flange structure; an upper shaft disc is arranged at the top end of the central rotary shaft; the bottom end of the central rotary shaft passes through a lower shaft disc and a top plate of a base, and is connected to the input shaft of a power generator arranged in a base through a shaft coupler; two blocking blocks which are matched with the crossed flangestructure of the shaft body of the central rotary shaft are separately fixed with the shaft body; the blocking blocks are of rectangular flat structures, the two short sides of the blocking blocks areequipped with horizontal fixed rods, and the same sides of the two long sides of the blocking blocks are separately equipped with a horizontal movable long rod and a horizontal movable short rod; thefront end of the movable long rod and the front end of the movable short rod are equipped with hinge connectors; the tail end of the movable long rod and the tail end of the movable short rod are separately hinged with the blocking blocks; the front end of the movable long rod and the front end of the movable short rod are connected to the inner side of a movable fan wing through hinges; a springis arranged between the tail end of the movable long rod and the front end of the movable short rod; and the front end of a fixed rod is connected to a fixed fan wing through a cylindrical groove. The lifting composite dual-form wind energy power generation device is mainly used for a subway tunnel.

Description

technical field [0001] The invention belongs to the field of new energy utilization, in particular to vertical axis wind energy generating equipment. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109MW, of which the usable wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts. [0003] Wind power generation has become the main way of current wind energy utilization. At present, there are two main types of wind power generation devices: horizontal axis wind turbines and vertical axis wind turbines. [0004] The horizontal axis wind turbine collects wind energy in a single direction. Even if it is used wi...

Problems solved by technology

[0006] According to the search, there are currently existing vertical axis tunnel wind power generation devices, such as the Chinese patent No. 200920195174.2 titled "A Tunnel Wind Power Generation Device". Under the low wind speed where tunnel vehicles pass, the wind energy utilization rate of the device is low

[0007] Another example is the Chinese patent No. 2013100945406 titled "A Resistance-Type Vertical-Axis Wind Power Generator". This patent provides a new solution for the design of a vertical-axis resistance type, which has the advantages of small starting wind speed, but it is difficult to operate at high wind speeds. Under the current situation, the amount of wind energy harvested is small, which inevitably leads to a decrease in the utilization rate of wind energy.
