Abstract
The utility model discloses a wind energy gathering device which is characterized by comprising a center pipe and a wind collecting pipe, and the center pipe and the wind collecting pipe are fixedly arranged. The wind collecting pipe is in a truncated cone shape. The center pipe is sleeved outside a wind driven generator. A small opening end of the wind collecting pipe is fixedly connected with the front end of the center pipe. At least two opening baffles are hinged in a circumference face of the wind collecting pipe. The wind energy gathering device has the advantages that when arranged on the wind driven generator, the wind energy gathering device is capable of increasing wind energy density of the wind which is blown to the wind driven generator, improving wind speed and enabling the wind driven generator to normally work under the condition that the speed of natural wind is low, and when the speed of the natural wind is high, the wind energy gathering device is capable of blowing the opening baffles which are hinged on the wind collecting pipe to form an opening, enabling the wind to be blown out from the opening, being in favor of even change of wind speed, and meanwhile expanding suitable wind speed range of the wind driven generator.
Description
Technical field
The utility model relates to a kind of wind-drive device of wind power generation field, relates in particular to a kind of wind energy apparatus for collecting.
Background technique
Wind-driven generator is one of electricity generating device, and its application is wider.But present wind-driven generator is subjected to the impact of wind speed larger; when the natural wind speed ratio hour; wind-driven generator can't normally start; and when the natural wind speed ratio is larger; be the 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 in the utility model is to provide a kind of wind energy apparatus for collecting that enlarges the applicable wind speed range of wind-driven generator.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of wind energy apparatus for collecting, comprise the center tube and the duct set that are fixedly installed, 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, is hinged with at least two open closure on the circumferential surface of described duct set.
Be fixedly installed extension spring between the internal surface of described duct set and described open closure.
The front end of described open closure is hinged on described duct set by hinge, and the rear end of described open closure is free end.
Described a kind of wind energy apparatus for collecting comprises base plate, and the bottom of the big opening end of described duct set is fixedly connected with described base plate by supporting frame, and described center tube is fixedly connected with described base plate by fixing frame.
The bottom of described center tube is provided with fluting, and the installation foot of described wind-driven generator passes described fluting and is fixedly connected with described base plate.
compared with prior art, the utility model has the advantages that by this device is arranged on wind-driven generator, can increase the wind energy density that blows to wind-driven generator, improve wind speed, make wind-driven generator in the situation that natural wind speed is less also can work, and when the nature wind speed is larger, the open closure that is hinged on duct set can be blown afloat opening of formation, allow wind blow out from opening, weakened the wind speed that blows on wind-driven generator, thereby wind-driven generator also can be worked when natural wind speed is larger, be conducive to the wind speed variation simultaneously uniformly, enlarged the applicable wind speed range of wind-driven generator.
Description of drawings
Fig. 1 is the utility model at natural wind speed structural representation hour;
Fig. 2 is the structural representation of the utility model when natural wind speed is larger;
Fig. 3 is the structural representation of A end in Fig. 1;
Fig. 4 is the structural representation at B place in Fig. 1.
