Abstract

The utility model relates to a wind-driven generator, which is characterized in that blade wheels are fixed on shaft ends; the shafts fixed with big gearwheels are movably installed on a gear box; caudads are fixed on the ends of the shafts on the gear box and drives the generator to generate electricity through the two-stage speed changing of the big gearwheels. Shafts are fixed on bolts in screwed connection with the inner side of the gear box. Bearing press covers are movably fixed on a pillar through bearings. The upper end of the pillar is provided with a circular orbit. Clamped in the circular orbit through an upper and a lower bearings, the gear box can rotate along the circular orbit. The wind-driven generator has the advantages of large wind contacting area of blade wheels, big axial force moment, high rotation speed of the generator and large power-generating capacity. The utility model can be popularized and applied in countryside in the north or mountain area with much wind.

Description

Wind-driven generator

The utility model relates to a kind of wind power utilization facility, is a kind of wind generating unit.

Wind-force is a kind of natural energy, and particularly the north had spring, autumn, three seasons of winter to blow in 1 year, and mountain area, Gao Yuanfeng are bigger, in recent years to some research of Wind Power Utilization, but utilizing wind-power electricity generation roughly the same, all is that impeller is directly installed on the generator shaft, blows the blade rotation generating when blowing, utilize battery to store utilization, this electricity generating device impeller and generator shaft are with speed, and generator speed is low, and generated energy is few, when only blowing hard, generated energy is just high.

The purpose of this utility model provides a kind of wind generating unit, as long as wheel rotation, generator is the energy high speed rotating just, and the electricity that just can send out a large amount of is to solve the few problem of the low generated energy of existing wind generating unit rotating speed.

The purpose of this utility model is achieved in that impeller shaft is movably arranged on gearbox top, an intrinsic gearwheel on the axle, the large gear turn the small gear, activity is fixed on the gearbox small gear by axle, by the coaxial small gear of going up on another gearwheel drive generator shaft, generator is by being bolted on the gearbox, gearbox inside thread attachment screw is fixed with axle, pass through bearing, the bearing gland activity is fixed in the column center hole, is propped up by column, and the column upper end is provided with track, the lower end is provided with flange seat, the gearbox outside is stuck on the track by the metal (upper wheel, when change of the wind, and can be under driving along orbit rotation to tail.

In order to make full use of wind-force, impeller diameter to be strengthened, there is wheel hub at its center, and there are axis hole and keyway in the wheel hub center, and the tube circle is arranged outward, and an intrinsic 4-16 blade between wheel hub and tube circle is provided with small leaf between outer circle two blades.

This model utility compared with prior art has the following advantages: (1) impeller contact wind face is big, and moment is big; (2) through two stage speed change generator speed height, generated energy is big; (3) the column upper end has track can reduce resistance, to guarantee that impeller is vertical with wind direction.

Be described further below in conjunction with accompanying drawing:

Fig. 1, wind power generation device structure schematic representation;

Fig. 2, wind generating unit plan view;

Fig. 3, impeller parts drawing.

Among Fig. 1-3: column (1) adopts steel pipe or aluminium to make, flange holder is arranged at the bottom, upper end intrinsic circular track (2), circular track (2) can adopt steel plate to make, there is the loss of weight vent hole at the middle part, under oblique stiffening rib is arranged, also can select for use channel-section steel to add horizontal stiffener and make with oblique stiffening rib, gearbox (7) is cast with iron and steel, and there is axle (3) inboard, there is screw thread the one end, the middle part side of having mother (4) has at least two screws on the square mother, it is threaded with gearbox (7), screw, its underpart is connected gland with column (1) bearing (19) to be fixed, and perhaps axle (3) is threaded bolt with column (1), it is connected with gearbox (7) bearing, and the top is fixed by the back-up ring nut.The gearbox opposite side is stuck on the track by metal (upper wheel (16), (17), can be along orbit rotation, lid (8) is arranged at gearbox (7) top, has impeller shaft (6) to pass, by the intrinsic gearwheel of key (9), axle (6) is connected gland (12) with the gearbox bearing fixing above.Small gear (10) matches with gear (9), it is coaxial with gearwheel (11), axle (14) is fixed on gearbox (7) upper press cover (15) by the bearing activity, small gear (17) matches with gearwheel (11), it is fixed on the generator shaft (16), and generator (16) is drawn by the column center by being bolted to electric wire on the gearbox (22) to tail (13).Impeller (5) is fixed together by key with axle (6), there is wheel hub (23) at its center, there are axis hole and keyway (24) in the wheel hub center, tube circle (27) is arranged outward, between wheel hub and tube circle (27), blade (25) is arranged, externally blade space is provided with small leaf (26), and impeller adopts glass or aluminum alloy to make.
