Problems solved by technology

The generator of this structure is an outer rotor generator, and the inner stator surrounds the central tower. In order to make the structure firm, the diameter of the central tower is generally made relatively large. Therefore, the diameter of the generator also needs to be made very large accordingly. The exciter should also be relatively large; for such a large equipment, installation and debugging are very troublesome, and the installation period is long and the installation cost is huge

Embodiment 1

[0042] Such as figure 1 As shown, a vertical axis wind power generator includes a central tower column 1 on which more than two power generation units are arranged. In this embodiment, the central tower column 1 is a hollow reinforced concrete center A tower column 1, the central tower column 1 is provided with two power generation units arranged up and down. The power generation unit includes a wind wheel 2 , a main gear 10 , and more than two generators 4 . In this embodiment, two generators 4 are arranged symmetrically around the main gear 10 ; the wind wheel 2 is a Φ-shaped wind wheel, and the wind wheel 2 is composed of two symmetrically arranged blades 21 . Such as image 3 , 4 As shown, the central tower 1 is provided with a first bearing 8 corresponding to the upper end of the wind wheel 2 , and the central tower 1 is provided with a second bearing 9 corresponding to the lower end of the wind wheel 2 . The upper end of the blade 21 is connected to the outer ring of...

Embodiment 2

[0065] This embodiment is basically the same as Embodiment 1, except that three power generation units arranged up and down are arranged on the central tower.

[0066] In addition, in the above-mentioned embodiments 1 and 2, the gear transmission system can also be any other combination of gears that can play a transmission role. For example, the gear transmission system includes a pinion, a worm gear and a The pinion is engaged, the shaft of the pinion is provided with a worm gear, and the shaft of the generator 4 placed horizontally is provided with a worm, and the pinion is connected with the shaft of the generator 4 through the structure of the worm gear and worm. The vertical rotation of the wheel 2 is transformed into the horizontal rotation of the generator 4, and for the vertical axis wind power generator 4, the installation of the generator 4 is simpler and more convenient.

[0067] The reinforced concrete central tower column adopted by the invention is convenien...

Abstract

Disclosed is a method for installation of a vertical-axis wind generator. The method comprises the following steps: (A) constructing the foundations of a central pylon (1); (B) constructing a reinforced concrete central pylon on the foundations; (C) installing a hoist (5) at the top of the central pylon; (D) each mounting platform (3), generator (4), wind wheel (2) and power generating device constituting a power generating unit, and according to the following steps, the hoist lifting successively from top to bottom all the power generating units: (a) lifting blades (21) onto the central pylon; (b) lifting a shaft coupling (6) onto the central pylon and connecting same with the wind wheel; (c) lifting a master gear (10) onto the central pylon and connecting same with the shaft coupling; and (d) lifting the generator and the power generating device onto the mounting platform, and meshing the generator with the master gear via a gear transmission system. The present method involves convenient installation and debugging, short construction time, and low costs.

Description

technical field [0001] The invention relates to a field installation method of a wind power generator, especially a vertical axis wind power generator. Background technique [0002] As we all know, wind turbines include two types of horizontal axis and vertical axis, and their power generation principles are basically the same. The power generation efficiency is related to the wind speed and the effective wind energy utilization area of ​​the wind rotor. Simply put, the larger the wind rotor, the higher the power generation efficiency. After years of development, horizontal-axis wind turbines have been better developed than vertical-axis wind turbines. The wind rotors of horizontal axis wind turbines have a higher utilization rate of wind energy than those of vertical axis wind turbines. After years of research on the horizontal axis wind turbine, it can be said that it has reached the bottleneck of technology, and it is difficult to make a major breakthrough. Due to the la...
