Abstract

The utility model is a beam-type vertical-axis wind power generator. The structure is that two or more sets of beams with equal angles are installed on the vertical main shaft, and each beam is equipped with a plurality of blades that swing with the wind. The blades are installed along the direction of the beam from the axis to the outside, and the blades swing with the wind. During the windward cycle, the blades will open against the wind to increase the windward area, and during the upwind cycle, the blades will close against the wind. Reduce the windward area. The utility model also installs a unique brake spring or brake column on the crossbeam. During the windward cycle, the fan blades are opened, and the brake spring or brake column determines the fan blade opening position. When the wind speed exceeds the set value The above-mentioned brake spring will be over-pressed and bend to make the windward area of the blade smaller to protect the power generation device. This method of directly reducing the windward area of the wind blade to protect the power generation device when the wind speed is too high is very important for current wind turbines. Said to be a huge change.

Description

A kind of vertical axis windmill of transversely arranged fan blade

Technical field:

The utility model relates to a kind of vertical axis windmill of transversely arranged fan blade, 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 the vertical axis windmill of a kind of transversely arranged fan blade of the utility model 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 utility model 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 utility model 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 utility model 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 utility model belongs to windage type tip-speed ratio greater than 1, even the design that can change fan blade changes tip-speed ratio.
