Description

A vertical axis wind turbine

technical field

The utility model belongs to the field of wind power generators, in particular to vertical axis wind power generation with multi-layer blades.

Background technique

In 2001, China took the lead in the research of new vertical axis wind turbines, led by the army, MUCE as the main body of research and development, with the cooperation of many experts from Xi'an Military Electric, Xi'an Jiaotong University, Tongji University, Fudan University and other universities, in just one year Within a short period of time, the world's first MUCE new vertical-axis wind turbine was produced. In the next few years, the vertical-axis wind turbine has been continuously improved. Currently, there are many kinds of Darrieus wind turbines on the market, such as Φ type, Δ type, Y type and H type, etc. These wind rotors can be designed as single blades, double blades, three blades or multi-blades, such as H-type vertical axis wind turbines, whose blades are all single-layer , and his wind rotor is also single-layer, so there will be a problem that the wind collection rate of single-layer blades is not high, and the working efficiency of wind turbines is not high when the wind is not strong. The output torque is unbalanced, and the range of output power changes greatly, so that the device itself is overworked and its service life is reduced.

Contents of the invention

The technical problem to be solved by the utility model is to provide a vertical axis wind generator with simple structure, good wind collection effect and stable output power fluctuation.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A vertical axis wind power generator, comprising a transmission main shaft and a wind rotor arranged on the transmission main shaft, characterized in that: the wind rotor includes a connecting rod and blades, the blades are connected to the transmission main shaft through the connecting rod, and the connecting rod is connected to the There is also at least one piece of small blade between the drive shaft and the drive shaft.

The transmission main shaft is provided with at least two layers of wind wheels along the axial direction, and each layer of wind wheels has the same structure.

The blades on two adjacent layers of wind rotors are axially staggered.

The length and width of the blade surface of the small blade is equal to or smaller than the length and width of the blade surface.

The blades and small blades adopt shuttle-shaped blades.

After adopting the above technical scheme: small blades are added between the blades and the drive shaft, the purpose of which is to ensure better wind collection when there is no wind or the wind is small, and the purpose of setting up multi-layer wind wheels is to enable Different output torques are superimposed on the drive shaft to ensure smoother torque fluctuations. the

Detailed ways

The utility model is an improvement on the basis of the existing vertical axis wind power generator. The existing vertical axis wind power generator adopts the principle of rare earth permanent magnet material to generate electricity, and the wind wheel matched with the principle of air hole mechanics adopts a direct drive structure. For rotating power generation, the existing vertical axis wind power generator includes a vertical axis wind power generation power supply system and an input power structure. The utility model is an improvement on the input power structure. Shaft wind power generators include a transmission main shaft 1 and a wind rotor 2 arranged on the transmission main shaft. The wind rotor 2 includes a connecting rod 3 and blades 4. The blades 4 are connected to the transmission main shaft 1 through the connecting rod 3. Specifically, two The parallel connecting rod perpendicular to the transmission main shaft is connected with the blades. The connecting rod 3 is also provided with at least one small blade 5 between the blade 4 and the transmission main shaft 1. The length and width of the blade surface of the small blade 5 are equal to or less than the length of the blade 4 Wide, the small blade 5 can be specifically arranged between two parallel connecting rods, the position can refer to Fig. 1, the blade 4 and the small blade 5 adopt shuttle-shaped blades. The transmission main shaft 1 is provided with at least two layers of wind wheels 2 along the axial direction. The structure of each layer of wind wheels 2 is the same, and the number of blades in each layer can be 2, 3, 4 or 5 pieces. The blades 4 are axially staggered.

Features of the utility model:

1) Small blades are added between the blades and the drive shaft. The purpose is to ensure better wind collection when there is no wind or the wind is small. The best effect of limiting the number of small blades is to set one. Because setting a small blade can guarantee the adoption efficiency under the premise of ensuring strong wind resistance.

2) The purpose of setting up multi-layer wind wheels is to enable different output torques to be superimposed on the drive shaft to ensure smoother torque fluctuations.
