Description

Wind tunnel type electricity generator

Technical field

The utility model relates to a kind of electricity generating device, and particularly a kind of active force drive vane of wind, steam, current of utilizing directly drives the wind tunnel type electricity generator that rotor rotates, and it is applicable to multiple generating place.

Background technique

At present, the generator of extensive use adopts traditional steam turbine generator, hydraulic turbine generator, wind wheel generator, diesel generator etc. mostly.Conventional construction is to drive the generator amature rotation by transmission shaft mostly, transmission shaft is subject to factor restrictions such as deadweight, self-contained bearing size, should not make king-sized structural member, so the just impossible large of the making of generator amature and stator, therefore the improvement to this electricity generating device has become the object that people generally study.The inventor once designed a kind of wind-driven generating device (patent publication No. is CN1807876A), and this machine adopts the wind gathering cover of being with leak informaton mouth and whirlwind honeycomb duct, and the multinomial technology such as blade of wind-tunnel, impeller and band knuckle thereof improve wind energy and render a service.But because of there is the drive mechanism complexity in it, impeller design not enough rationally single-machine capacity does not have big defectives such as breakthrough, is further improved.Patent publication No. is that EP1350952A1's disclose a cover wind-force equipment in " be equipped with vertical rotation wind force device ", it is equipped with a vertical rotor, be assembled in a generator that rotor bottom drives with transmission device, the blade that is used to drive rotor in a large number on the assemble rotor, around director element system that rotor radial is arranged, and utilize top cover in the director element shell as valve, the position of the counterweight that covers by adjustment is controlled the valve opening degree automatically, reaches best generating effect to adjust wind gathering power size.This apparatus structure more complicated is installed, debugging is pretty troublesome, particularly to the adjustment of valve counterweight, must measure maximum estimated wind-force and middle storm just can mate by a measuring system.If measure, estimate wrong, light influence generating effect then, heavy then damaged blade.Notification number be CN1237270C's " band cover wind motor ", it mainly comprises a wind-driven generator and is used for hour increasing the member of the wind speed that blows to generator and reduce the member of the wind speed that blows to generator when wind speed being big at wind speed.Its main effect is to reduce the wind gathering amount, rather than directly stops the impact of high wind to impeller blade.Because of adopting move mode, it adjusts the position of generator in air guide member, in case transmission device is malfunctioning, then can't mobile generator, and just do not had the effect of regulating wind speed.More than two documents all are the problems that solve wind gathering amount size, can not when superpower wind speed, keep out the wind, function ratio is more single.Existing electricity generating device drives the generator amature rotation by transmission shaft mostly, still has nothing to do directly to drive the report that rotor rotates in sleeve rotor and impeller.

The model utility content

The purpose of this utility model provides a kind of wind tunnel type electricity generator, and its reasonable in design obviously improves generating efficiency, it can wind gathering when wind speed is more weak, improve wind energy renders a service, again can wind sheltering when superpower wind, prevent that effectively parts are impaired, operation ensures safety.

The purpose of this utility model is achieved in that this machine comprises and is fixed on the casing that has adjustable fan housing on the rotation plate type pedestal and assembles stator in it, rotor and blade, its technological points is: week is fixed together with vane tip in the described rotor, rotor is contained in the stator by bearing pack, and the slideway of rotor periphery is rotated along the guide rail on the dunnage of casing both sides, described adjustable fan housing is made up of the barge board that is hinged on the connecting plate periphery, connecting plate is fixed on the dunnage sidepiece of casing, the cylinder ends of oil hydraulic cylinder is hinged on the connecting plate by bearing pin, the piston crown of oil hydraulic cylinder is hinged on the barge board, and the Driven by Hydraulic Cylinder barge board is swung around hinging shaft.

The described connecting sleeve that is fixedly connected on the blade in week in the rotor is assembled on the central support shaft.

Because the utility model adopts hollow wind tunnel type rotor structure, and week is fixed together with vane tip in the rotor, rotor is contained in the stator by bearing pack, and the slideway of rotor periphery is rotated along the guide rail on the dunnage of casing both sides, so the blade in the wind-tunnel can rotate by direct driving rotor, cancel traditional transmission shaft, so reasonable in design, generating efficiency obviously improved.The adjustable fan housing of forming by the barge board that is hinged on the connecting plate periphery in addition, under the driving of oil hydraulic cylinder, automatically adjust the intake grill size, thus can wind gathering when wind speed is more weak, improve wind energy effectiveness, again can wind sheltering when superpower wind, prevent that effectively parts are impaired, operation ensures safety.
