Abstract

Disclosed is a wind generator with vertical shaft and is a wind gathering device, comprising a lower plate, an upper plate and an aviation baffle. Shaft holes are arranged on the central parts of the lower and the upper plates. A bearing is arranged in the shaft hole. The bearing supports a vertical shaft with a wind scoop. The wind gathering device intensively gathers the wind from the windward direction to the wind scoop, causing the vertical shaft to drive a rotor of the generator to rotate and to generate electricity. The wind gathering device is cylindrical. No matter how the wind direction changes, wind can be intensively accelerated to blow and to rotate the vertical shaft by using the aviation baffle to gather wind. The utilization ratio of wind can be increased to 83-93%. An electric power station with the wind generator with vertical shaft has the advantages of less investment, fast effect and obvious effectiveness.

Description

Wind generator with vertical shaft

Belong to class generator.

Existing wind-driven generator, the rotor shaft of generator all are levels, and the rotor shaft front end is equipped with the wind wheel that facings the wind and rotate, and wind wheel rotates under the blowing of wind-force, and wind wheel rotates the rotor rotation that drives generator and generates electricity.The wind wheel of this generator, the useful area that facings the wind is very little, and is lower to the utilization ratio of wind-force, makes the economic benefit of generator very poor.

The purpose of this utility model is: improve the utilization ratio of wind-driven generator to wind-force, increase the economic benefit of wind-driven generator.

The technical solution of the utility model is: increase the wind-exposuring area of wind-driven generator, the wind on the windward side is drawn in by wind deflector, form the air-flow that quickens, air-flow is concentrated and is blown on the vertical shaft that has wind scoop, and the rotor rotation that vertical shaft drives generator makes it generating.

Fig. 1 is the stationary power generation station schematic representation that utilizes vertical-shaft aerogenerator of the present utility model to build, and Fig. 2 is a top plan view.

6 is upper plates of vertical-shaft aerogenerator among the figure, the 2nd, lower plate, upper plate and lower plate all are the circles of level, all there is axis hole the central position, bearing is housed in the axis hole, metal (upper is supporting the vertical shaft 4 that has wind scoop, between upper plate 6 and lower plate 2, circumferentially be distributed with 12 vertical wind deflectors 5, one side and wind axis 4 outer rims of wind deflector 5 are tangent, for rigidity and the intensity that increases wind deflector 5, the support plate 3 of parallel upper plate 6 and lower plate 2 can be set between wind deflector, the rotor of the lower end of vertical shaft 4 and generator 1 links, by upper plate 6, lower plate 2, the wind-gathering device that wind deflector 5 constitutes, whole cylindrical, so no matter how this device wind direction changes, can both be by the gathering of wind deflector, with blowing in the wind scoop on the vertical shaft 4 that wind is concentrated, make the rotor rotation generating of generator, such wind-gathering device can make the effective rate of utilization of wind-force bring up to 83～93%.

This fixed vertical-shaft aerogenerator power station, below lower plate 2, office, work cell, Generators etc. can have been built, can build recreation room, meteorological office on upper plate 6, uppermost room covers can be by dress lightning conductor, satellite earth antenna and meteorological equipment.Can equip elevator in the side.Reinforced concrete construction can be adopted in this large-scale power station.

Fig. 3 is structural representation small-sized, removable vertical-shaft aerogenerator, and Fig. 4 is top plan view. 1 is generator, the 2nd among the figure, lower plate, the 6th, and upper plate, the 4th is equipped with the vertical shaft, the 5th of wind scoop, wind deflector, the 7th, frame.

In a word, vertical-shaft aerogenerator can be built large-scale fixed power station, also can build the power station of small movable. There is small investment in this power station, instant effect, the obvious characteristics of benefit.
