Abstract

The invention discloses a variable-leaf-surface barrel type wind driven generator comprising blades, a middle shaft, connecting rods, a counterweight flange, an upper end cover, a lower end cover, a top sealing cap and slender rods; one end of the middle shaft is connected to the upper end cover, and the other end of the middle shaft is connected to the lower end cover; and the top end sealing capis installed on one end of the middle shaft, the counterweight flange is slidably installed on the middle shaft, the counterweight flange is connected to one ends of the connecting rods, the other ends of the connecting rods are connected to the blades, and the blades are provided with the slender rods capable of freely turning over. The risk of failure of a pure electromagnetic brake function iseffectively reduced by means of the lifting and lowering of the counterweight flange and the variable leaf surface. When the wind driven generator is at a low rotation speed, the frontal area of theleaf surface is large, as the rotation speed is improved, the leaf surface is displaced to reduce the frontal area, the frontal area of the blades is reduced, and then the rotation speed is graduallyreduced, so that the rotation speed of the wind driven generator is maintained in a normal working state.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a bucket type wind power generator with variable blade surface. Background technique [0002] As a renewable, non-polluting natural energy source, wind power is very environmentally friendly and can generate huge amounts of electricity, which has gradually attracted people's attention. Therefore, more and more countries pay more attention to wind power generation. A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The vertical axis wind turbine does not need to face the wind when the wind direction changes. Compared with the horizontal axis wind turbine It is a big advantage, it not only simplifies the structural design, but also reduces the gyroscopic force when the wind wheel faces the wind. However, the existing vertical-axis wind turbines have fixe...
