Abstract

The utility model discloses a wind guide buttress with an internally mounted rotating wheel for wind power generation equipment, which belongs to the technical field of structures of wind power generation equipment and aims to overcome the shortcomings that a current buttress for wind power generation equipment is single in function and the intrinsic value of the current buttress is not explored. The wind guide buttress with the internally mounted rotating wheel for the wind power generation equipment comprises a buttress composed of at least two vertical wind guide wings for transversely guiding wind; the rotating wheel is perpendicularly mounted among the wind guide wings around a central shaft; bearings are mounted at two ends of the central shaft of the rotating wheel and fixed onto the wind guide wings through supports; and the central shaft of the rotating wheel is connected with a power generation device. The wind guide buttress is applicable to new construction and reconstruction projects of buttresses for the wind power generation equipment.

Description

The wind-guiding of wind power plant is also adorned the buttress of runner within it

Technical field

The utility model relates to a kind of structure technology of wind power plant, and the wind-guiding that particularly relates to a kind of wind power plant is also adorned the buttress of runner within it.

Background technique

Recently, China National Bureau of Oceanography has announced that in the first batch " can develop no resident island register, " relates to totally 176 no resident islands, 8 provinces and regions such as Zhejiang, Liaoning, Shandong.So-called no resident island just is meant unmanned island, just in China seas under its jurisdiction not as island, cay, the low tide highland of permanent resident population residence.Undoubtedly, in the near future,, will carry out the development ﹠ construction of unprecedented scale, allow these desert islands become the human island of serving of each tool function one by one on these uninhabited in the past islands.Obviously, the specialty no matter which kind of function these unmanned island plans build into is used the island, at first carries out the development ﹠ construction of wind energy power thereon, but is only selection.This be because, in the development process on these island with after building up, all must power supply, and will go over from the continent transmission of electric energy, high power supply cost becomes the obstacle that can't go beyond; And,, do not have chain of mountains barrier because the space is open on these island, and ocean surface, regional bay, wind resource is very abundant, for wind-power electricity generation provides very superior natural condition.In Zhejiang, had company to go ahead of the rest, invest nearly 1,000,000,000 yuan, a desert island Construction of Wind farm, put into operation now specially, and generate electricity and can carry back continent And to go into national grid, obtained good social benefit and economic benefit.In the face of thriving wind-power electricity generation development ﹠ construction prospect, feel necessary carry out the research and development on the wind generating technology and the improvement of installations and facilities.For example, the high buttress that towers just plays the effect of supporting fan blade at present, does not also develop other function of its inherence.

Summary of the invention

The purpose of this utility model provides a kind of wind-guiding of wind power plant and adorns the buttress of runner within it, overcomes the buttress function singleness of present wind power plant, the deficiency that its inherent value is not excavated.

The utility model is achieved by following technical proposals.

The utility model comprises buttress, described buttress is made up of the wind-guiding wing of two upright horizontal wind-guidings at least, by central shaft runner is housed vertically between the described wind-guiding wing, bearing is equipped with at the central shaft two ends of described runner, and described bearing is fixed on the described wind-guiding wing by support; The central shaft of described runner is connected with electricity generating device.In the design of the present utility model, originally the buttress of cylinder type is improved to the assemblying body that at least two upright horizontal wind-guiding wings are formed, as support member, original windward side structure is become wind-guiding shape structure, the wind load of constructing body is alleviated greatly, improved the Security of constructing body.Simultaneously, from the wind-force of different direction, the guiding through the described wind-guiding wing flows to described runner, makes described runner high speed rotating, and then drives the electricity generating device generating that is connected with its axis.

Can more effectively guide the wind energy that blows from each different direction in order to make the described wind-guiding wing, described runner can be rotated more reposefully, the quantity of the described wind-guiding wing is selected in four to eight scopes, is symmetry axis with the central shaft center line of described runner, is provided with axisymmetrically.The preferred described wind-guiding wing of the utility model is six, is symmetry axis with the central shaft center line of described runner, is provided with axisymmetrically.

In structure of the present utility model, be actually in the inside of former buttress again the wind-driven generator of development device one cover vertical shaft, the function of buttress is effectively expanded.Consider that from the angle that can admit wind energy more the layout of the described wind-guiding wing on the warp-wise area should be unfolded.

Against existing technologies, the beneficial effects of the utility model are:

Make the function of the buttress of wind power plant obtain excavating, make full use of its value; The wind load of buttress is greatly alleviated, improved the Security of buttress.

Description of drawings

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1.Among the figure: 1, the wind-guiding wing, 2, runner, 3, the central shaft of runner, 4, support.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

In the present embodiment, the wind-guiding wing 1 is six, is symmetry axis with the central shaft center line of described runner, is provided with axisymmetrically.At first, built the wind-guiding wing 1, and support 4 has been installed on two ends up and down of the member that the wind-guiding wing 1 formed, assembled the used bearing of central shaft 3 of runner at the center up and down of support 4 according to diagram and relevant building code.Assemble the central shaft 3 and the runner 2 of runner at last, simultaneously an end of the central shaft 3 of runner is connected with electricity generating device.Debug qualified after, can come into operation.Present embodiment is except that the function of the rotation fan blade on supporting top, the function of its wind-guiding and generating is expressed as follows: the wind-force that blows from which direction no matter, guiding through the wind-guiding wing 1, can both turn to making runner 2 right handed wind-force, so, as long as wind is arranged, runner 2 can gyrate, thereby sends electric energy continuously by the central shaft 3 drive electricity generating devices of runner.On the other hand, owing to the structural feature of the wind-guiding wing 1, increased the rated wind velocity of whole member.
