Abstract

The utility model relates to a wind driven generator with a vertical-axis micro-power magnetic loop and an energy gathering ring, which comprises a main shaft, wherein a bearing is fixedly arranged on the main shaft with a boss, a casing is arranged on the bearing, an energy gathering ring is arranged on the inner side wall of the casing, the inner side of the energy gathering ring is provided with a magnetic head, a stator receiving disk is also arranged on the main shaft in the casing, the main shaft close to the upper face of the stator receiving disk is fixedly provided with a stator disk, and a coil is arranged on the outer wall of the stator disk. The wind driven generator with the vertical-axis micro-power magnetic loop and the energy gathering ring has a compact structure and reasonable design. An injection-molding rotor winding disk is generally adopted for a wind driven generator, so that the wind driven generator has the following defects that the mechanical strength is low, and the physical performance is not stable; a generator body is easy to age and deform when being heated up to 60 to 70 DEG C, and the condition that a winding coil is heated up because of the friction of a rotor and a stator occurs frequently, so that a magnet falls off so as to cause the phenomenon of blockage of the rotor and the stator; and the failure rate is high, the utilization rate of the magnet is low, a loop of a magnetic field does not exist inside the generator, the output power of power generation is low and the like. According to the wind driven generator with the vertical-axis micro-power magnetic loop and the energy gathering ring, the breeze power generation of the small-sized wind driven generator is truly realized, the output power is stable, the efficiency is high, the aim of power generation by breeze is realized (the wind speed per second is 2 meters), and strong wind is controllable.

Description

Vertical axis microkinetic magnetic loop energy-gathering ring wind-driven generator

Technical field

The utility model relates to a kind of a kind of small-sized wind power generator that utilizes the generating of gentle breeze kinetic energy, especially relates to a kind of.

Background technology

At present, small-sized wind power generator all exists teeth groove moment big both at home and abroad, in the gentle breeze environment, can't start operation; Generating is renderd a service low, can't surely control the generating power output, and gentle breeze does not generate electricity; Wind is out of control greatly, and the materials used mechanical strength is low, non-refractory; Operation produces temperature arrising caused by friction expansion modification between rotor and the stator when body is warmed up to 60-70 ℃, damages magnet and winding coil, often blocks accident defects such as generator.

Summary of the invention

The purpose of the utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, the vertical axis microkinetic magnetic loop energy-gathering ring wind-driven generator that power output is high.

In order to achieve the above object, the technical scheme that the utility model adopts is: comprise main shaft, have on the main shaft of boss and be fixed with bearing; Housing is housed on it; The housing madial wall is provided with energy-gathering ring, and there is magnetic head its inboard, stator also is housed on the main shaft in housing connects dish; The main shaft that connects on the dish near stator is fixed with stator discs, on its outer wall coil is housed.

The utility model has the advantages that:

Compact conformation, reasonable in design, wind-driven generator generally adopt injection moulding rotor winding dish, and mechanical strength is low; Physical property is unstable, and body is prone to aging distortion in the time of intensification 60-70 ℃, rotor and stator friction winding coil often takes place heat up; Magnet is come off, cause rotor and stator stuck phenomenon, failure rate is high; The magnet utilance is low, inner the no field circuit of generator, defective such as the power output of generating electricity is low.The utility model is really realized the small-sized wind power generator breeze wind, and the power output stabilization efficiency is high, and breeze wind (2 meters of per second wind speed) strong wind is controlled.
