Single-blade horizontal axis airscrew type wind power generator

Abstract

The present invention discloses a single blade level shaft propeller type wind generator which adopts a design of a single blade and a balance damper and effectively improves the wind energy using rate, and solves the problems such as the 'runaway' problem of the conventional wind generator. A grain friction type clutch solves the problem that the start of the single blade wind generator is difficult. And the manufacturing cost of the wind generator is low, so it is redound to popularize the wind generator.

Description

technical field [0001] The invention belongs to a wind power generator, in particular to a single blade horizontal axis propeller type wind power generator. Background technique [0002] The horizontal axis propeller wind turbine is the main type of wind turbine used in large quantities at present. This form is the most efficient form of wind energy utilization known so far. According to the Bernoulli theorem in fluid mechanics and aerodynamics, it is composed of The airflow works through the power generated by the upwardly curved and downwardly flat airfoil blades, and its wind energy utilization efficiency is much higher than that of other forms of wind turbines. [0003] At present, the wind turbine blades widely used in the world are two-blade, three-blade, four-blade or multi-blade. The number of wind turbine blades is inversely proportional to the speed. The more blades, the lower the speed. The fewer the blades, the higher the speed . [0004] The horizontal axis pr...

AI Technical Summary

Problems solved by technology

[0005] The existing multi-blade design of the horizontal axis propeller blade wind turbine is easy to vibrate due to the unbalanced force of the wind force during the rotation of the blades. When the problem is serious, it will be caused by the vibration of multiple blades at the same period. Harmful resonances can cause serious damage to wind turbines

[0006] Due to some uncontrollable factors, such as lightning hitting the power equipment of the generator, the work of the generator will be affected, resulting in the phenomenon of "speeding" of the motor due to the load shedding at super high speed, which will damage the entire wind turbine and affect the entire power generation. cause huge losses

[0007] The blades of multi-bladed wind turbines generally need to be selected in groups of two, three or even multiple blades. During the selection process, many blades may not be matched and cannot be used, resulting in A lot of waste, high technical costs, and high manufacturing costs
