Abstract
The utility model discloses a folding blade-type wind machine, in which two folding blades (1) that are axial-symmetrically distributed are driven by wind to rotate around a blade shaft (2), and when the folding blades rotate to a vertical position, the utilization of wind energy achieves a maximum value, while the maximum limit of the utilization ratio thereof can be up to 75%. In order to solve rotation angle problem of the blades of the wind machine, in the utility model, two groups of blades are designed specifically and arranged vertically. The blades (1) rotate to drive the blade shaft (2) and a gear ring (3) to rotate, wherein the gear ring (3) is supported by six uniformly-distributed bearings (4), two sets of gear rings are engaged and transmitted by a gear ring transmission shaft (5) and a pinion (8) on the shaft, and a gear transmission shaft (6) is engaged with the gear ring (3) and a gear (7) which is arranged on the blade shaft (2). The transmission design aims at ensuring the angular velocity of the blades (1) to be identical with that of the blade shaft (2), and synchronous rotation can be realized by engagement of the pinion (8) on the gear transmission shaft (6).
Description
Technical field
The utility model is about a kind of novel form of collecting folk songs of wind-power electricity generation.
Background technique
The background that wind-power electricity generation produces is to shine upon earth surface, and the earth surface difference of being heated everywhere produce the temperature difference, thereby the convective motion that causes atmosphere forms wind, and its energy that carries is a wind energy.Thereby the moving blower fan rotation of wind drives the generator rotary electrification and claims that wind-power electricity generation is a wind-powered electricity generation.Wind energy is a kind of reformulations of solar energy, is a kind of renewable natural energy resources that does not produce any disposal of pollutants.Compare with solar energy, biology, underground heat and power generation with marine energy, wind-powered electricity generation is the new energy of current techniques and economically tool commercial scale exploitation condition.
The wind energy resources of China is very abundant, estimates according to National Weather Service, and China 10m height is about 1,000,000,000 kW with the interior earth surface wind electric energy that develops, land 2.5 hundred million kW wherein, marine 7.5 hundred million kW, if expand to the above height of 50～60m, wind resource will be expected to expand to 20～2,500,000,000 kW.Therefore, wind-power electricity generation is the reality of China's energy sustainable development and important selection.
Summary of the invention
The purpose of this utility model is to avoid existing pneumatic equipment blades made to get the deficiency of wind area and a kind of new product is provided.The technical solution of the utility model is that folding blade type wind energy conversion system comprises folding blade, sharf, gear ring, bearing, gear ring transmission shaft, gearing shaft, gear, small gear.It is characterized in that the folding blade of described two axisymmetric rotates at wind-engaging, angle of rotation difference and blade be folding thereupon, stretch.The blade area of folding blade above when the vertical position is stretched over maximum area, and this moment, the utilization of wind energy reached maximum value, and when effective wind-engaging zone that the folding blade of wind energy conversion system covers, the utilization ratio of wind energy upper limit (UL) can reach 75%.When departing from the vertical position with the rotation the angle difference, following folding blade begins to stretch, when it forwards horizontal position to, the lower blade that the blowing area of upper blade is rotated up blocks fully, lower blade is subjected to rotate with all strength and to the vertical position, make folding, the stretching, extension of two blade alternates, last down conversion.In the blade rotary course, prevent from that interfolded is stressed to break that the rotation of gear ring and the rotation of sharf are must angular velocity identical, increase the gearing shaft engagement driving for this reason, make that sharf and gear ring are synchronous.Fold blade for overcoming blade rotation horizontal position to the axisymmetric that the unbalance stress of vertical position is provided with two groups of vertical arrangement, by gear ring transmission shaft engagement driving.The utility model has been owing to adopted the collapsible blade structure, thereby overcome the deficiency that wind sweeping area is little, blade ribs cost is high of traditional wind energy conversion system.Can solve effectively and make full use of wind energy and make wind energy conversion system be able to the problem of popularization and application, can obtain bigger power output.
The utility model is compared with other wind energy conversion system, and simple in structure, low cost of manufacture, efficient height, output power are big.
