Embodiment Construction

[0039] Bottom-drive wind turbines include a wind power transmission part, a mechanical transmission part, a speed-increasing part, a speed-regulating power generation part, a control part, a nacelle and a tower; The tower tube flange 20 is connected with the tower tube 29 . The wind power transmission part includes blades 51 and hub 1; blades 51 are connected to hub 1 through flanges, and hub 1 is installed at the front end of nacelle 21; blades 51 rotate under the action of wind to generate power, and hub 1 and the mechanical transmission behind Partially connected to transmit the rotational power generated by the blade 51;

[0040] A pitch changing device 2 is installed at the root of the blade 51, and the pitch changing device 2 is movably connected with the blade 51. Under the action of the pitch changing device 2, the blade 51 can rotate around the hub 1 in a circle. Between the blades 51 change angles to find the best angle of attack and improve the utilization rate of ...

Abstract

A wind generating set with bottom driving comprises a wind power transmission portion, a mechanical driving portion, a speedup portion, a speed regulation generating portion, and a control portion. The power generated by rotation of blades under the effect of wind power is transmitted to a main shaft through a wheel hub. The main shaft is connected with two bevel gear sets for changing direction and speeding up twice, and an output shaft is a crankshaft which is formed by three connecting rod necks, the torsion moment generated by an impeller is transmitted to the crankshaft at the bottom of a tower cylinder through transmission steel pipes. The output shaft at the bottom of the tower cylinder connects a gear case to carry out speedup, six groups of speed regulation generating devices are introduced, each group comprises two sets of speed regulation generating devices, each of which comprises a sprocket wheel, a clutch, a buncher stepless gear, and a generating set. The present invention has the advantages of low cost, stabilized generating frequency, direct access, convenience in market popularization, and requires no expensive frequency converter, and therefore, has significant economic benefit and wide application prospects.

Description

technical field [0001] The present invention relates to a wind power generating set, and specifically relates to a wind power generator that is different from the wind power generators on the market: First, the wind power generator of the present invention omits the frequency conversion device used for grid connection, and adopts a continuously variable transmission for speed change The second is that the present invention adopts the structure that the power is moved down, and the power generation equipment is installed on the ground, which can reduce the equipment cost by 30% to 50%. The quality of power generation is poor, and the bottom-drive horizontal axis wind turbine can not be directly connected to the grid. Background technique [0002] Today, when human beings are faced with two urgent problems of energy and environment, the use of clean energy such as wind energy, water energy, and solar energy, which is known as green and environmentally friendly energy, has been...
