Description

Louvered Vertical Axis Wind Turbine

technical field

The utility model relates to an improved vertical axis wind power generator, which belongs to the technical field of wind power engines.

Background technique

With the depletion of global chemical energy, wind power has attracted more and more attention. The vertical axis wind turbine has the advantages of high wind energy utilization rate, low start-up wind speed, and basically no noise, etc., and has broad application prospects. The fan blades of existing vertical axis wind turbines are generally integral structures, that is, the entire fan blade is a blade, and there are two main disadvantages: one is that the area of a single blade is relatively large, and it is difficult to finish and transport it. Install. Second, limited by the shape and size of a single blade, the entire fan should not be enlarged.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a louver type vertical axis wind power generator which is convenient for processing, transportation and installation and has unlimited size.

Problem described in the utility model is realized with following technical scheme:

A louver-type vertical axis wind power generator, comprising a tower, a generator, a vertical main shaft and a plurality of fan blades, the generator is fixed on the tower, its output shaft is fixedly connected to the vertical main shaft, the The fan blade is composed of a rectangular grid blade holder and a plurality of blades. The rectangular grid blade holder is fixedly connected to the vertical main shaft through an assembly frame and a bushing. Each rectangular grid of the rectangular grid blade holder corresponds to a blade. Vertical blade shafts are arranged on the blades and are rotatably connected to the rectangular grid blade frame through the blade shafts, and a blade limiting piece is also arranged in each rectangular lattice of the rectangular grid blade frame.

In the above mentioned louver type vertical axis wind power generator, there are three fan blades, which are all distributed around the vertical main shaft.

The fan blade of the utility model is composed of a rectangular grid blade frame and multiple blades. The area of the fan blade is determined by the blade size and the number of blades. The size of a single blade does not need to be large, so it is convenient for processing, transportation and Install. In addition, the power of the fan can be adjusted by changing the number of blades on each fan blade, which can be made small or large, without being limited by the shape and size of a single blade.

The utility model has the advantages of convenient processing and transportation, simple and quick installation, high utilization rate of wind energy and wide power range, and is especially suitable for areas with good wind energy conditions, far away from power grid or abnormal power grid.

Detailed ways

1 to 6, each blade of the utility model is composed of a rectangular grid blade frame 5 and a plurality of single blades 6, and each rectangular grid blade frame 5 is evenly spaced and installed at a certain angle. The single-piece blade is hot-press-cast with an open steel mold. The blade has high precision and low cost, and is suitable for large-scale production.

During installation, the tower 1 is first fixed at the selected position, the generator 2 and the vertical main shaft 3 are fixed on the tower 1, the blade limit piece 7 is fixed on the rectangular grid blade frame 5, and then the single blade 6 Install it on the rectangular grid blade frame 5, then install the rectangular grid blade frame 5 on the assembly frame 4, install the shaft sleeve 8 on the vertical main shaft 3, the assembly frame 4 and the shaft sleeve 8 of each fan blade fixed. The three fan blades form an included angle of 120 degrees (this angle is related to the number of fan blades). When the wind blows the blade 6 to swing to the position of the blade limit piece 7, the blade 6 stops swinging, and the whole fan blade drives the vertical main shaft 3 to rotate under the push of the wind. When the vertical main shaft 3 rotates 180 degrees, the blade stops The sheet 7 no longer blocks the swing of the single-piece blade 6, and the whole fan blade is not stressed. The three fan blades are stressed one after another, thereby driving the generator 2 to generate electricity.

The utility model can be started at a low wind speed, has no noise, and is a silent wind power generator. It is generally applicable to areas with good wind energy conditions, far away from the power grid or abnormal power grid, for power consumption of household appliances (such as TV sets, lights, etc.), monitoring facilities, communication equipment and other small and medium-sized power-consuming facilities. The utility model can also be connected to the grid to generate electricity, and the power of the fan can be large or small, ranging from tens of watts to several megawatts.
