Abstract

The utility model relates to a wind powered generating device, in particular to a vertical axis type large scale wind generating set. The wind powered generating device has the technique proposal that: a plurality of Yin Eight Diagrams walls, a funnel door and a cylinder wind wheel, a plurality of Yang Eight Diagrams walls are arranged at the outer side of the cylinder wind wheel, the funnel door is covered outside the cylinder wind wheel, a plurality of Yin Eight Diagrams walls are arranged outside the funnel door to form a wind inlet; the funnel door wall of the funnel door is butted with the Yin Eight Diagrams walls to form a wind inlet channel which drives the cylinder wind wheel to rotate for generating the electricity. The wind powered generating device has the advantages that: firstly, the static Eight Diagrams walls are used to replace dynamic paddles, which solves the wind passing area problem and reduces the cost and the operational difficulty; secondly, the 45 DEG included angles of the Eight Diagrams walls are used, the space controlled by the Eight Diagrams walls forms a wind funnel, therefore, the goal of quickly adjusting the speed wind is achieved, and because the wind speed in the tail of the funnel door is proportional to the area of the Eight Diagrams walls, the wind speed can be adjusted according to needs; thirdly, a super-large scale wind generating set can be built according to needs.

Description

Perpendicular axis type large-scale wind electricity unit

One, technical field:

The utility model relates to a kind of wind generating unit, particularly relates to a kind of perpendicular axis type large-scale wind electricity unit.

Two, background technique:

Along with the surging impact of oil price, global warming constantly raise and reason such as greenhouse gas emission, started the voice of exploitation renewable energy sources in the world.Wherein the wind-powered electricity generation exploitation is the most important thing, the wind-powered electricity generation exploitation mainly is to finish by wind power generating set, it is to be the machinery of electric energy with wind energy transformation, the wind-powered electricity generation exploitation of China also is in the starting stage, main force's type of producing is horizontal shaft type 600～750kw wind-powered electricity generation unit at present, body is huge, and rotor diameter and pylon height reach more than 50 meters.The rotor diameter of external megawatt-level wind unit and pylon are unexpectedly up to more than hundred meters.The problem of its existence is: the difficulty of the design of body, manufacturing, lifting is very big.In addition, since Dane's invention wind power generating set in 1891, research large-scale wind electricity unit is the target that western countries are pursued always, but two hang-ups that influence wind-powered electricity generation unit output power fail effectively to solve always, for example: the one, power is directly proportional with the wind area of crossing of blade, the west is in order to pursue the high-power the most clumsy way of just having used: " rising pylon height strengthens blade area ", thus increased difficulty for designing, make, lifting; The 2nd, cube being directly proportional of power and wind speed, both 1 times of the every raising of wind speed then output power just can improve 8 times, visible wind speed is the important indicator that influences power.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of perpendicular axis type large-scale wind electricity unit is provided, problem to be solved is to substitute dynamic blade with static Eight Diagrams wall, not only solved the difficulty of crossing the problem of wind area but also having reduced cost and operation, the 2nd, utilize the angle of Eight Diagrams wall, make Eight Diagrams wall control the space expert funnel that becomes a common practice, thereby reach the purpose of transferring fast wind speed.

Its technological scheme is: mainly install a plurality of cloudy Eight Diagrams walls, funnel door and cylindrical body wind wheel at base, be provided with a plurality of Yang Baguabi in the described cylindrical body wind wheel outside, the cylindrical body wind wheel is with the funnel door outward, and funnel is installed a plurality of cloudy Eight Diagrams walls, the wind inlet of formation outdoors; The cloudy Eight Diagrams wall butt joint of the funnel Men Biyu of described funnel door forms air intake passage, drives cylindrical body wind wheel rotary electrification.

Preferred scheme is that base can be a square, and a plurality of cloudy Eight Diagrams wall of installing above forms the wind funnel, forces the air-flow of flowing through to quicken.

Further preferred scheme is that the funnel door is provided with a plurality of funnel door walls, and the radial direction of funnel Men Biyu funnel door is installed at an angle, and each funnel door wall is corresponding with each cloudy Eight Diagrams wall respectively, forms air intake passage, forces the air-flow of flowing through further to quicken.

Detailed is that described a plurality of cloudy Eight Diagrams wall is eight; Described a plurality of Yang Baguabi is eight.

Its working principle is: the basic principle of utilizing Eight Diagrams " cloudy Eight Diagrams perseverance is quiet; positive Eight Diagrams perpetual motion; to swinging coexistence ", adopt static cloudy Eight Diagrams wall to substitute dynamic blade, action of high-speed airflow by the funnel door forces cylindrical body wind wheel high speed rotating in Yang Baguabi, thereby the realization wind energy transformation is a mechanical energy, mechanical energy is connected with generator by speed change just can to reach wind energy transformation be electric energy.

The beneficial effects of the utility model are: the first, substitute dynamic blade with static cloudy Eight Diagrams wall, not only solved the difficulty of crossing the problem of wind area but also having reduced cost and operation; The second, utilize the angle of a plurality of cloudy Eight Diagrams walls, make cloudy Eight Diagrams wall control the space expert funnel that becomes a common practice, thereby reach the purpose of transferring fast wind speed, because " wind speed of funnel door afterbody is directly proportional with the area of Eight Diagrams wall ", so can adjust wind speed as required; Three, can build super sized type wind-powered electricity generation unit as required.
