Abstract
The utility model discloses a flat turn open and close type wind wheel which is used to generate electricity and comprises a base and a wind wheel shaft, wherein a bearing is arranged on the wind wheel shaft and wind wing frame is connected on the bearing. The wind wheel shaft is vertical to the ground, the wind wing frame takes a cross shape and is symmetrically arranged around the wind wheel, a plurality of wind wing doors are arranged on the wind wing frame, each wind wing door can rotate on a door spindle, and wind wing door frames are located on one side on the wind wheel rotating direction relative to the wind wing doors. The wind wheel shaft of the utility model is vertical to the ground, the wind wheel adopt a flat turn mode, the wind wing frame is extended around, each wind wing can be made long and can reach tens of or hundreds of meters, which greatly exceeds the size of a blade type wind wheel, the resistance of the wind wing is smaller than that of the blade type wind wheel, and the wind wheel can rotate faster and more forceful. The purpose for increasing the power generation efficiency is achieved.
Description
One, technical field
The utility model relates to a kind of wind wheel that is used to generate electricity.
Two, background technique
National wind-power electricity generations such as the U.S., Germany, Denmark are T﹠B, in recent years, China also from these national imports the technology of relevant wind-power electricity generation aspect built tens wind power plants.At present, the blower fan of wind-power electricity generation all is a paddle formula wind turbine, and the wind wing is made of the paddle of two, three, four symmetric arrangement, and the utilization ratio of this fixedly paddle formula wind turbine wind is very low.The power source of wind-power electricity generation is a wind, and the utilization ratio of wind is low, wind wing rotating speed is slow, directly influences generating efficiency.Fixedly paddle formula wind turbine vertical rotating is limit by structure, and its electric motor power can not be too big, and the single-machine capacity of existing wind-driven generator is at 5～7 megawatts, 1500 kilowatts of domestic single-machine capacities.Present wind-driven generator the biggest in the world is in the U.S., more than 10 ton of weight of a paddle, and more than 60 meter is long, 8000 kilowatts of single-machine capacities.China is vast in territory, the wind regime abundance, and it is stronger to set up large-scale wind generating factory advantage.And have only large-scale wind wheel just can obtain large-sized power, and single-machine capacity is increased, China's wind-power electricity generation is rapidly developed.
Three, summary of the invention
The purpose of this utility model provides a kind of open and close type wind wheel of flatting turn of generating electricity and irrigating of being used to, and the utilization ratio height of wind can improve generating efficiency.
The technical solution adopted in the utility model is: the open and close type wind wheel of flatting turn comprises base, rotor shaft, and bearing is arranged on rotor shaft, is connected with wind wing frame on the bearing.Rotor shaft is perpendicular to the ground, and wind wing frame is cross-shaped symmetrical and is arranged in around the rotor shaft, and a plurality of wind wing doors are arranged on the wind wing frame, and each wind wing door can rotate on door-hinge, and wind wing doorframe apparent wind wing door is in the same side of wind wheel sense of rotation.When wind, wind blows closure with the wind wing door of a crosswind wing frame, make the wind wing frame of this side have bigger windage, thereby rotated by wind, the wind wing doorframe of another crosswind wing frame is in side with the wind relatively simultaneously, wind wing door is opened by wind, so only have less windage, can not influence whole wind wheel and rotate.
Rotor shaft of the present utility model is perpendicular to the ground, and wind wheel adopts the mode of flatting turn, and wind wing frame is to stretching all around, each wind wing can be done very longly, can reach tens meters even hundreds of rice, substantially exceeds the size of paddle formula wind wheel, wind wing resistance is also little than paddle formula, and wind wheel can change sooner, stronger.Reach the purpose that improves generating efficiency.

Fig. 2 is a plan view of the present utility model;
Fig. 3 is the structural representation of the utility model wind wing door.
Five, embodiment
The open and close type wind wheel of flatting turn comprises base 1 and rotor shaft 8, and rotor shaft 8 is welded on the base 1, becomes one with base 1.Bearing 2 is enclosed within on the rotor shaft 8, and sleeve 5, bag lock 3 and gear 4 are arranged on the bearing 2, and wind wing frame 7 is connected with bearing 2 by sleeve 5.Rotor shaft 8 is perpendicular to the ground, and wind wing frame 7 is cross-shaped symmetrical and is arranged in around the rotor shaft 8, and a plurality of wind wing doors 6 are arranged on the wind wing frame 7, and each wind wing door 6 can rotate on door-hinge 13 separately, and wind wing doorframe 11 apparent wind wing doors 6 are in the same side of wind wheel sense of rotation.On the top of rotor shaft 8 axle cap 10 is arranged, between axle cap 10 and each wind wing frame 7, stay cord 9 is arranged; Between adjacent wind wing frame, horizontal stay cord 12 is arranged.Bag lock 3 is used for the braking of wind wheel.Gear 4 is used for outwards transmitting power, during use generator drive axle is linked together through gearbox and gear 4.
