Problems solved by technology

Today in the 21st century, although more start-up assistance has been done on the Dalieu (lift) model, such as adding a set of S-type resistance blades inside the H-type lift-type vertical axis wind turbine to Increase the starting performance, but also increase the cost due to the complex structure, and also cause wind resistance to affect the power generation efficiency

Embodiment Construction

[0011] Such as figure 1 As shown in (a), the three lift-type blades 1 of the wind wheel supported by the bracket 3 and the bracket 3 are fixed on the shaft of the generator 4 and can rotate. The generator 4 is installed on the tower rod 8. 2 are connected by a hinge 7, and there is an elastic reset block 6 between the roots of the connection. There is a groove in the middle of the starting auxiliary wing 2, which leans against the nylon spacer 5 of the support 3 under the elastic force of the elastic reset block 6, and the nylon spacer 5 plays a buffering role.

[0012] As shown in Figure 2(a), when the wind W blows, since the lift blade 1 is connected to the bracket 3, the open wind-receiving surface S1 formed by the lift blade 1 and the starting auxiliary wing 2 forms a pushing resistance, so when the wind blows, The wind wheel rotates around the center of the wind wheel and reaches speed V. During the rotation acceleration process, the starting aileron 2 is affected by th...

Abstract

A vertical-axis wind generator with starting auxiliary wings comprises three lift blades (1), starting auxiliary wings (2), and a support (3), wherein the starting auxiliary wings (2) are connected through hinges (7), the support (3) for supporting the lift blades (1) is rotatable and is fixed on a shaft of a generator (4), the generator (4) is mounted on a pole (8), and an elastic return block (6) is arranged between each lift blade (1) and the corresponding starting auxiliary wing (2). The vertical-axis wind generator has the advantages that starting performance of the lift-structure wind generator is improved through the simple-structure auxiliary wings while the efficiency of the lift-structure wind generator is unaffected; the starting auxiliary wings can automatically adjust the operating states thereof according to wind speed and rotation speed and start operating at low wind speed, and the efficiency is unaffected at high wind speed.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a vertical axis lift type wind power generator with starting auxiliary wings. Background technique [0002] The vertical-axis lift-type wind turbine was born in the 1930s (1931). It was invented by Dalieu, and its wind energy utilization coefficient and practicability have reached a high level. There are defects in the self-starting performance, and the safety problem under high wind speed has not been well resolved, so it has not been widely promoted. Today in the 21st century, although more start-up assistance has been done on the Dalieu (lift) model, such as adding a set of S-type resistance blades inside the H-type lift-type vertical axis wind turbine to Increase the starting performance, but also increase the cost due to the complex structure, and also cause wind resistance to affect the power generation efficiency. Therefore, the simplest structure is used t...
