Non-backbone turntable-type vertical shaft wind turbine

Abstract

The invention discloses a non-backbone turntable-type vertical shaft wind turbine in which an iconic structure that blades and brackets of the classical and traditional vertical shaft wind turbines rotate around the backbone is concealed. The diameter of a blade rotating circle and the vertical length of the blade are directly increased on a turntable; the torque of the wind turbine is increased; main parts, except for nodes of the bracket, are hidden inside the blade in a penetrating manner; the resistance of the bracket is changed into powder of the blade; the rotation mode of an outer rotor is abandoned; a vertical shaft is driven by the turntable; a rotating shaft generator is directly driven by the vertical shaft; a generator is arranged between the turntable and a fixed plate; a power supply is provided for turntable equipment; the angle of the blade is adjusted by the motor; lubricating oil is automatically filled into a pivotal bearing which works in the sky. The non-backbone turntable-type vertical shaft wind turbine is applicable to large and medium-sized wind power systems.

Description

technical field [0001] The invention relates to a vertical axis wind turbine, in particular to a vertical axis wind turbine without a backbone rotating disk. Background technique [0002] The horizontal axis wind power generation system is the mainstream type of wind power generation in the world today, with mature technology and large production batches. However, the disadvantages of horizontal axis wind turbines are also becoming more and more obvious. Its starting wind speed is high, its working noise is large, and its wind resistance is poor. The above gear gearbox is difficult to realize the direct drive of the wind turbine to the generator. The height of the tower or tower of the megawatt-level wind power generation system is 70-80M, the diameter of the blade circle is up to 100M, the length of the blade is 50M, and the total weight of the wind turbine equipment carried by the yaw slewing bearing is up to 100 tons. : The horizontal axis wind power generation system h...

Problems solved by technology

[0008] 2. In the classic and existing vertical axis wind turbines, to increase the torque, the diameter of the blade rotation circle and the vertical length of the blade cannot be directly increased, but the support must be enlarged and strengthened first, and then the diameter of the blade circle and the blade vertical length can be increased. Vertical length (the diameter of the arc-shaped blade can represent its average vertical length)

[0010] 4. In the classic and existing vertical axis wind turbines, the blades and their brackets rotate around the trunk. This structure is not conducive to the introduction of power on the brackets, and it is impossible to use motors to adjust the angle of the blades on the rotating brackets (existing vertical axis wind turbines) The blade angle of attack adjustment devices of the machine are all mechanical), and the electric oil pump cannot be used to automatically fill the slewing bearing on the blade rotating shaft with lubricating oil
