Abstract
The utility model discloses an electric generator provided with impellers, comprising a rotating part and a static part, wherein the rotating part comprises a rotor, and the static part comprises a stator; the electric generator also comprises an impeller structure, the impellers and the rotor of the electric generator are integrated, and the impellers are arranged on the rotor. The electric generator has the advantages that as the impellers and the electric generator are integrated into a whole, a speed increasing device does not need to be arranged between the impellers and the electric generator like the prior art when the electric generator is applied to a power generating system, and the defects of cost increase, fault rate increase and high maintenance cost, which are caused by the speed increasing device in the prior art can be overcome. The electric generator provided with the impellers is applicable to various power generating systems of wind power, ocean current, tide, low-water-head river and the like.
Description
Technical field
The utility model relates to a kind of generator, particularly a kind of generator that has impeller.
Background technique
Generator is a kind of kinetic energy to be converted into the equipment of electric energy, existing generator, and its structure mainly comprises the part of stationary part and rotation, and stationary part contains stator, coil, and rotating part then contains rotor etc.Rotor wherein is permanent magnet or conductor, and the permanent magnet of rotation produces magnetic field, and the coil cutting magnetic line on the stator produces charge inducing and realizes generating.Therefore generator is extensive use of for example ocean current power generation, tidal power generating, tidal power generation, wind-power electricity generation, low water head generating etc. in power generation system.These power generation systems, all adopt natural force to generate electricity, utilize the natural force drives impeller to rotate, the impeller that rotates rotates for transmission of power rotor again to drive generator amature, but, the rotating speed of impeller runs up because can't making generator amature produce, thereby the impeller that utilizes natural force to rotate need promote speed by speeder, realize running up to drive generator amature, thereby realization generator for electricity generation, because existing speeder adopts mechanical transmission such as gear to carry out more, just make rate of fault rise the maintenance cost height, thereby make the operating cost height of power generation system, restricted the development of electric power.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the generator that has impeller that a kind of rate of fault is low, maintenance cost is low, operating cost is low is provided.
The generator that has impeller comprises rotating part and stationary part, and rotating part comprises rotor, stationary part comprises stator, its structure outline is: described generator also includes blade wheel structure, and the rotor of described impeller and generator is an integral structure, and impeller is set on rotor.
In the rotor of the forwarding motor of generator and the structure that impeller is made integral type, just can utilize the mutual supporting effect of impeller and rotor, play the purpose that strengthens the generator diameter, when various natural forces promote wheel rotation, rotor with the impeller one will be followed rotation, and the stator of generator induces electric power just can realize generating, the electricity generating device of the generator system of this form, need not as prior art, between impeller and generator, speeder to be set, just can realize the requirement of generating electricity.Therefore it has solved prior art because the rate of fault height that speeder brings is set, maintenance, the shortcoming that operating cost is high.
The integral structure of impeller and rotor is, rotor is arranged to the form of impeller, adopts permanent magnet or electric conductor to make in whole impeller.
Described rotor is a kind of hollow rotor, and impeller is arranged at the inner chamber of rotor.
So just can utilize the blade of impeller to play the effect of support rotor,, on the blade of impeller, rotor is set simultaneously, solve the strength problem of impeller blade again to strengthen the structural rigidity problem of large-diameter rotor.
The stationary part of generator is provided with coupling arrangement, and described coupling arrangement or be the anchor earrings can connect with fixed body in any form and makes generator not by displacement.
Described rotor adds epoxy resin by stainless steel or other waterproof insulation material environmental sealing is antirust.
Adopt the generator that has impeller of this structure, applicable to rely on low water head, morning and evening tides, etc. the power generation system relevant with current.
In sum, advantage of the present utility model is:
The utility model is by impeller and generator are closed and two be one, like this when being applied to power generation system, need not as prior art, between impeller and generator, speeder to be set, thereby the cost that can change in the prior art with speeder brought increases, rate of fault increases, the shortcoming that maintenance cost is big.The generator that has impeller of the present utility model, or be applicable to multiple power generation system, such as wind-force, ocean current, morning and evening tides, low water head river etc.
