Abstract
A wind energy generator with foldable type horizontal fan blades comprises a vertical rotating shaft, blades, generator groups and a hollow tower barrel, wherein the vertical rotating shaft which is arranged in the tower barrel is in pivot joint with the tower barrel, and more than two blade seat frames are arranged at the top end of the vertical rotating shaft. One ends of the blade seat frames are fixed with the vertical rotating shaft, and the other ends of the blade seat frames are provided with rotating devices which are fixedly connected with the roots of the blades. Fan blades are in T-shaped structures, the blades can be longer and wider, namely the wind-facing area of the blades can be larger, and accordingly the utilizing rate of wind energy is higher. When the wind is particularly strong or a typhoon happens, the blades which are horizontally arranged originally can change to be vertically arranged through the rotating devices, and accordingly wind-facing area is greatly reduced. The wind energy generator with the foldable type horizontal fan blades adopts the most direct and most effective speed-reducing method, thereby being simple in operation. The folded blades are prevented from being blown off in strong wind, and accordingly the service life of the whole generator groups is prolonged.
Description
Technical field
The utility model relates to wind-driven generator, especially has the hybrid wind-driven generator of horizontal blade and vertical rotation axis.
Background technique
The main effect of wind-driven generator braking mechanism has two aspects: the one, need the vanes fixed of wind power generating set is motionless during overhaul of the equipments, and the 2nd, running into wind-force is to avoid damaging generator set the vanes fixed of wind power generating set not to be changeed when brute force or typhoon especially.The brake modes of existing wind-driven generator mainly contains the brake system of mechanical braking mechanism and variable pitch type.The water brake mechanism that the braking mechanism of machinery generally is made up of brake disc, brake block and hydraulic control device, the brake disc of this kind braking mechanism is fixed on the main shaft of group of motors, and brake block is controlled by hydraulic control device.When running into wind-force especially when brute force or typhoon, for the protection wind power generating set is damaged because of the overpower generating, hydraulic control device control brake block clamping spindle, make its slow-down, thereby limited the rotating speed of generator, changed in the brake process and whole active forces all is added on the brake block always, this makes mechanical vibration big, the brake block quick abrasion also is not suitable for daily maintenance; The brake system of variable pitch type is to reach by the wind-exposuring area that changes blade to reduce the stressed of blade, thereby reduce the speed of blade, this kind mode comes in handy under general high wind, but for the wind-force of typhoon class, there is very big risk in this kind brake modes, and braking effect is general.All there is a key issue in above-mentioned two kinds of brake modes, even effect is gathered in brake, the blade of wind-driven generator is also probably blown disconnected by high wind, cause the infringement of generator set.
