Abstract
The invention relates to a beam type vertical axis wind-driven generator which is characterized in that fan blades are arranged outwards from an axle center along the direction of a beam, and meanwhile, the wind blades are swung with wind; during a period in the wind, the wind blades can be opened in the wind, and during a period against the wind, the wind blades can be closed against the wind soas to reduce frontal areas. In the invention, the beam is also provided with a special brake spring or a brake column, during the period in the wind, the wind blades are opened, and the opening positions of the wind blades are decided by the brake spring or the brake column. When wind speed exceeds a set value, the brake spring can be excessively pressed and bent to ensure that the frontal areas of the wind blades become small so as to protect a generating device, and the mode of directly reducing the frontal areas of the wind blades to protect the generating device when the wind speed is toohigh is a great change for the wind-driven generator at present.
Description
Technical field:
The present invention relates to a kind of beam type vertical axis wind-driven generator, specifically a kind of blade structure that changes traditional vertical axis aerogenerator, can make from small-power to powerful vertical axis aerogenerator.
Background technique
The installation of existing its fan blade of vertical axis aerogenerator mostly is above-below direction or parallel in vertical shaft, and a kind of beam type vertical axis wind-driven generator of the present invention fundamentally changes blade structure, and the installation of fan blade is outwards assembled by the axle center along the crossbeam direction.Fan blade of the present invention is that the described fan blade of swinging with the wind when the cycle of facining the wind can open down with the wind to increase wind-exposuring area simultaneously, contrary wind during the cycle described fan blade can leeward closure reduce wind-exposuring area, and at present other vertical axis aerogenerator mostly be greatly fixedly fan blade contrary wind during the cycle wind-exposuring area can minimizing can not influence effect.The present invention's fan blade when distinctive brake spring or brake posts also are installed on the crossbeam in the cycle of facining the wind opens by described brake spring or brake posts decision fan blade deployed position; thereby when wind speed surpass to be set numerical value described brake spring can pressurized excessively and bending diminishes described fan blade wind-exposuring area to protect electricity generating device, thisly directly reduce the fan blade wind-exposuring area to protect the mode of electricity generating device when wind speed is excessive be a kind of huge change for present wind-driven generator.Only need use brake posts in the area that does not have typhoon or hurricane in order to simplify then.
Its fan blade of existing vertical axis windmill and horizontal-shaft wind turbine or blade support how to be fixedly mounted on the main shaft respectively thereby the installation requirement that on main shaft, needs quite high, and the present invention can pass main shaft with a section bar and becomes symmetrical two groups of crossbeams and its center of gravity of fan blade and just in time make structure quite simple and the high cost that makes of intensity significantly reduces in the vertical major axle center.
Existing windage type (or claiming resistance type) the blade tip linear velocity of its fan blade of vertical axis aerogenerator and the ratio (tip-speed ratio) of wind speed are generally less than 1, and wing blade (or claim lift-type) tip-speed ratio can it is said even can reach 6 greater than 1, yet its tip-speed ratio is being arranged under the situation of rated load also near 1, can be under loaded situation but the invention belongs to windage type tip-speed ratio greater than 1, even the design that can change fan blade changes tip-speed ratio.
Summary of the invention
The object of the invention be with simple mode fundamentally improve vertical axis aerogenerator in application aspect high-power, the present invention passes vertical major with a section bar to be become symmetrical two groups of crossbeams and its center of gravity of fan blade and just in time makes structure quite simple and the high cost that makes of intensity significantly reduces in the vertical major axle center, many section bar different heights pass vertical major with impartial angle becomes 4 groups or 6 groups or more groups of symmetrical crossbeams and fan blade, and described many section bars pass vertical major with different height and need insert vertical pin and pin not on the same group crossbeam.
Its fan blade of the present invention can be divided into multi-disc and outwards be assembled by the axle center along the crossbeam direction on a crossbeam, fundamentally change the blade structure of traditional vertical axis windmill.Fan blade of the present invention is that the described fan blade of swinging with the wind when the cycle of facining the wind can open down with the wind to increase wind-exposuring area simultaneously, contrary wind during the cycle described fan blade can leeward closure reduce wind-exposuring area, and at present other vertical axis aerogenerator mostly be greatly fixedly fan blade contrary wind during the cycle wind-exposuring area can minimizing can not influence effect.
The present invention's fan blade when distinctive brake spring or brake posts also are installed on the crossbeam in the cycle of facining the wind opens by described brake spring or brake posts decision fan blade deployed position; thereby when wind speed surpass to be set numerical value described brake spring can pressurized excessively and bending diminishes described fan blade wind-exposuring area to protect electricity generating device, thisly directly reduce the fan blade wind-exposuring area to protect the mode of electricity generating device when wind speed is excessive be a kind of huge change for present wind-driven generator.Only need use brake posts in the area that does not have typhoon or hurricane in order to simplify then.
Fan blade of the present invention can be made monolithic type or biplate type up and down according to the design needs.
Fan blade of the present invention is arranged the quantity that can set fan blade according to the length of design needs and crossbeam along crossbeam, and in general the fan blade area of the big far-end of the fan blade area of the paraxial heart is less.
Fan blade of the present invention is installed and can directly be enclosed within on the cylindrical beam, also can be installed on the blade support, in general small-sized less can directly being enclosed within on the crossbeam of its crossbeam diameter, and the crossbeam diameter bigger or the described fan blade of non-cylindrical crossbeam can be installed on the blade support.
Blade support of the present invention only need be installed a pack support at the monolithic type fan blade, for biplate type fan blade up and down two pack supports need be installed, and one group of auxiliary stand also need be installed simultaneously.
Auxiliary stand of the present invention is used for installing brake spring or brake posts.
Blade support of the present invention is that a support is installed a plurality of fan blades, gains in strength as need the blade support reinforcing device can be installed.
The large-scale plant middle cross beam span that the present invention is directed to the high-power vertical shaft wind-driven generator more greatly solution heavy burden problem solve with cable, can realize the design of high-power vertical shaft wind-driven generator like this.
