Abstract
The invention discloses a sliding type wind energy density increasing device, which is characterized by comprising a central tube, an air collecting tube and a sliding mechanism, wherein the central tube is arranged outside a wind driven generator in a sleeving manner, the small port end of the wind collecting tube is fixedly connected with the front end of the central tube, and the wind collecting tube is fixedly connected with the sliding mechanism. The invention has the advantages that the sliding type wind energy density increasing device is mounted on the wind driven generator; the intensity of the wind energy blown to the wind driven generator is increased; the wind speed is improved; the wind driven generator can also operate under the condition of lower natural wind speed; when the natural wind speed is higher, the wind collecting tube and the central tube move backwards along a guide rail since the wind driven generator is fixed; the large port end of the wind collecting tube is close to the wind driven generator, as a result, the effect of the wind collecting tube is weakened under the condition of higher natural wind speed; the wind driven generator can also operate normally under the condition of higher natural wind speed; and the application wind speed range of the wind driven generator is enlarged.
Description
Technical field
The present invention relates to a kind of wind-drive device of wind power generation field, particularly relating to a kind of sliding type wind energy density increases device.
Background technique
Wind-driven generator is one of electricity generating device, and its Application comparison is wide.But current wind-driven generator is larger by the impact of wind speed; when natural wind speed ratio is less; wind-driven generator cannot normally start; and when natural wind speed ratio is larger; for protection wind-driven generator; wind-driven generator will be in guard mode and quit work, and therefore, make the applicable wind speed range of wind-driven generator narrow.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sliding type wind energy density being suitable for wind speed range expanding wind-driven generator increases device.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of sliding type wind energy density increases device, comprise center tube, duct set and slide mechanism, described duct set is frustoconic shape, described center tube is enclosed within outside wind-driven generator, the osculum end of described duct set is fixedly connected with the front end of described center tube, and described duct set is fixedly connected with described slide mechanism.
Described slide mechanism comprises base plate and fixed guide rail, the bottom of the big opening end of described duct set is fixedly connected with described base plate by supporting frame, described center tube is fixedly connected with described base plate by fixing frame, the lower surface of described base plate is fixedly installed slide rail, described slide rail coordinates with described slide, described guide rail is fixedly installed fixed block, between the front end of described fixed block and described slide rail, is fixedly connected with extension spring.
Described guide rail is installed with block, and described block is positioned at the rear of described slide rail.
The bottom of described center tube and described duct set is provided with chute, and the installation foot of described wind-driven generator maintains static through described chute.
The upper rear end of described center tube is hinged with baffle plate, the area described baffle plate being positioned at hinged place upper section is greater than the area being positioned at hinged place inferior portion, and the area described baffle plate being positioned at hinged place upper section is less than the area of described duct set big opening end.
Compared with prior art, advantage of the present invention is by being arranged on wind-driven generator by this device, the wind energy density blowing to wind-driven generator can be increased, improve wind speed, wind-driven generator also can normally be worked when natural wind speed is less, and when nature wind speed is larger, because wind-driven generator maintains static, natural wind blows duct set and center tube slides backward along guide rail, the big opening end of duct set is near wind-driven generator, make duct set declines when natural wind speed is larger, thus wind-driven generator also can normally be worked when natural wind speed is larger, expand the applicable wind speed range of wind-driven generator, this device also helps and impels wind speed to change evenly simultaneously, improves the generating efficiency of wind-driven generator, in addition, again because the upper rear end of center tube is hinged with baffle plate, when natural wind speed is little, baffle plate is larger with the angle of center tube, wind flow through wind-driven generator is smooth and easy, when natural wind speed is larger, the angle of baffle plate and center tube diminishes, reduce the exhaust outlet area of center tube, wind speed through wind-driven generator is reduced, protection wind-driven generator is not damaged, wind-driven generator also normally can be worked when natural wind speed is larger, expand the applicable wind speed range of wind-driven generator further.
