Problems solved by technology
[0002] Rigid connections are used between the rotating components and the fixed components of existing vertical axis wind turbines, and the wind rotor is fixedly installed on the main shaft or transmission shaft. Tight connection, there can be no relative displacement between the connecting rod of the wind wheel or the wind wheel and the main shaft or the transmission shaft. The resonance of the transmission shaft, especially when developing a large vertical axis wind turbine, the weight of the wind wheel will be very large, the vibration caused by it is also very strong, and the damage to the wind turbine is also great

Embodiment Construction
[0010] see Figure 1-3 , the present invention provides an automatic vertical structure adapted to a vertical axis wind power generator, including a tubular outer casing 2 and an upper bearing sleeve 3 for rotational connection with a central axis (main shaft) 5, and the upper bearing sleeve is installed on The axial middle part of the jacket is in clearance fit with the inner wall of the jacket. An O-ring is provided between the upper bearing sleeve and the jacket. The machine rotor (preferably the outer rotor generator) is connected as a rotating component, driven by the wind to rotate around the central axis, and generate electricity through the generator. Through the setting of the above upper bearing sleeve, the central shaft can be designed as a half shaft (extending from the lower end of the outer sleeve to the middle of the outer sleeve), and its upper end is connected to the outer sleeve through the upper bearing 4 installed on the upper bearing sleeve, thus not only ...

The invention relates to an automatic verticality structure applicable to a vertical-axis wind turbine. The automatic verticality structure comprises a tubular jacket and an upper bearing sleeve. The jacket is used for being rotationally connected with a center shaft. The upper bearing sleeve is mounted in the axial middle in the jacket, and is matched with a gap of the inner wall of the jacket. O-shaped rings are arranged between the upper bearing sleeve and the jacket. The jacket is allowed to curve and swing by a certain degree, so that damage to the center shaft and obstruction to equipment operation due to curving of the jacket are reduced or avoided; imbalance caused by curving and swinging of the jacket is absorbed and reduced through elastic deformation of the O-shaped rings, so that operation stability and reliability are guaranteed, and automatic verticality is realized; the automatic verticality structure is mainly applied to the vertical-axis wind turbine.
Description
technical field [0001] The invention relates to an automatic vertical structure adapted to a vertical axis wind power generator, belonging to the technical field of wind power generation. Background technique [0002] Rigid connections are used between the rotating components and the fixed components of existing vertical axis wind turbines, and the wind rotor is fixedly installed on the main shaft or transmission shaft. Tight connection, there can be no relative displacement between the connecting rod of the wind wheel or the wind wheel and the main shaft or the transmission shaft. The resonance of the transmission shaft, especially when developing a large vertical axis wind turbine, the weight of the wind wheel will be very large, the vibration caused by it is also very strong, and the damage to the wind turbine is also great. [0003] A new type of design is to put a tubular casing on the fixed central shaft (main shaft), and the fan blades and the outer rotor of the gene...
