Vertical-axis wind driven generator with transverse ribs arranged on blades

Abstract

The invention discloses a vertical-axis wind driven generator with transverse ribs arranged on blades. The vertical-axis wind driven generator comprises a case, a generator body, two traction steel rods, a fixed cross beam, a spindle and three blades, wherein the three blades are evenly distributed in the peripheral direction of the spindle and fixedly connected with the spindle, and each blade has a hook face with curvature radius becoming larger gradually from bottom to top; a top plate and a bottom plate are installed above the blades and below the blades respectively, and both the top plate and the bottom plate are arranged on the spindle in a sleeving mode and fixedly connected with the spindle; the two ends of the fixed cross beam are fixedly connected with a top cover of the case through the two traction steel rods respectively, the upper end of the spindle is connected to the fixed cross beam in a rotary mode, and the lower end of the spindle penetrates through the top cover of the case to stretch into the case; the generator body is installed in the case and connected to the lower end of the spindle; the top plate and the bottom plate are each provided with multiple through holes. The wind driven generator is convenient to install, easy to start and simple in design.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to a vertical axis wind power generator with transverse ribs on the blades. Background technique [0002] With the development of the new energy industry, people pay more and more attention to the utilization of wind energy. According to the rated power of wind turbines, they are generally divided into: microcomputer (below 10kW); small computer (10kW to 100kW); medium-sized computer (100kW to 1000kW) and large computer (above 1000kW, MW-level fan). [0003] Wind turbines (hereinafter referred to as "fans") are mainly composed of two parts: the wind turbine part-converts wind energy into mechanical energy; the generator part-converts mechanical energy into electrical energy. The generator part of the fan can be an asynchronous generator or a synchronous generator. [0004] Commonly used fans are horizontal-axis wind turbines, which have the following disadvantages: (1) larg...

AI Technical Summary

Problems solved by technology

[0004] Commonly used fans are horizontal-axis wind turbines, which have the following disadvantages: (1) large volume, high center of gravity, inconvenient installation, need to be fixed by drawing fibers, and easy to fall when encountering strong wind; The requirements are high, and it is difficult to start power generation in the breeze area; (3) It is necessary to install a windward device to ensure that the impeller of the wind turbine is always at the position of the maximum wind receiving surface, which increases the difficulty of simple fan design
