Abstract

The utility model relates to a horizontal flywheel wind-mill generator which is characterized in that the wheel flange of a horizontal flywheel is evenly distributed with a set of blades 1; the shape of each blade is a streamline body, one end of the streamline body is an opening, the cross section of the streamline body is triangle, and the triangle gradually shrinks to the tail end until gathering into a point; a flywheel shaft 6 is connected with a generator 11 by adopting a shaft coupling 9, a storage battery pack 10 is connected in parallel with the output terminal of the generator so as to supply power to a storage battery when power is supplied to users during wind blowing, and the storage battery supplies power to users when no wind exists. As the technical scheme is adopted, the utility model has the following advantages: 1. the horizontal flywheel occupies no space, and can be put at places such as roof, balcony, etc; 2. the utility model has small volume, low cost and high safety; 3. the blades can be installed in multilayer, and the frontal area of the blades is big, and thus, the rotary speed of the flywheel is fast and the power is large.

Description

Horizontal flywheel wind power generator

Technical field:

The utility model relates to a kind of electricity generating device, particularly a kind of wind-driven generator.

Background technique:

Along with the develop rapidly of World Economics, increasing to the demand of electric power, because of the thermoelectricity coal consumption big, the pollution that is caused is quite serious, and therefore, people utilize the energy of nature energy in searching, as wind-driven generator, it is one is the ancient research topic that presents generation again.So-called wind-driven generator, it basic composition is fan blade and links to each other with generator by mechanical transmission, described fan blade all is vertical, if will obtain bigger power, just need very huge fan blade, therefore just need tall and big tower structure to support huge fan blade is installed, it takies bigger space and floor area, therefore its construction cost is higher, and flexibility is also relatively poor; Huge fan blade is difficult for safety enclosure is installed, so its Security is relatively poor.Extensively retrieve at the problems referred to above, still find no solution related to the present invention.

Summary of the invention:

The purpose of this utility model is exactly a kind of horizontal flywheel wind power generator that designs in order to solve the above-mentioned defective that exists in the prior art.

To achieve these goals, the utility model has adopted following technological scheme:

A kind of horizontal flywheel wind power generator, it is made up of generator and wind force device, it is characterized in that described wind force device forms by horizontally disposed flywheel and along one group of fan blade that flywheel rim is provided with, the rotating shaft that flywheel joined is connected with alternator shaft by mechanical connecting device.Described fan blade be shaped as an end opening, cross section triangular in shape, caudad shrink until the fairing that converges to any gradually, its quantity can be 2-20, along the uniform setting of flywheel rim.The flywheel rotating shaft can adopt coupling directly to be connected with alternator shaft, also can adopt the umbrella gear that is coupled in the flywheel rotating shaft and umbrella gear on being coupled to alternator shaft to match and be connected.Can be in generator output end battery pack in parallel, so as when wind to be arranged in user's power supply to the storage battery power supply electric power storage, power to the user by battery pack when calm.

Owing to adopted technique scheme, made to the utlity model has following advantage: 1, the horizontally disposed flywheel side of occupation of land not can be placed on places such as roof, balcony; 2, volume is little, cost is low, safe; 3, fan blade can the multilayer setting, and wind-exposuring area is bigger, so the flywheel rotating speed is fast, power is big.

For the utility model is described in further detail, following accompanying drawing provides two most preferred embodiments of the present utility model.

Description of drawings:

Fig. 1 is the utility model embodiment 1 a plan view;

Fig. 2 is the plan view of the flywheel among Fig. 1;

Fig. 3 is the stereogram of Fig. 1, fan blade shown in Figure 2;

Fig. 4 is the utility model embodiment 2 a plan view, has omitted battery pack.

Embodiment:

As shown in Figure 1 and Figure 2, horizontally disposed flywheel is made up of wheel hub 4, spoke 3 and wheel rim 2, uniform on the wheel rim 28 fan blades 1 are set, the structure shape of fan blade 1 as shown in Figure 3, its opening end 1b, sectional shape is triangular in shape, be contracted to tail end 1a left gradually, and converge and be a bit, the following 1c of fan blade 1 is welded on the wheel rim 2, and the opening of fan blade 1 all is in the same direction as.Turn back to Fig. 1, connect a rotating shaft 6 in the axis hole of wheel hub 4, its upper end is fixing with wheel hub 4 with nut 5.The middle part of rotating shaft 6 is supported by bearing 8, is fixed by axle sleeve 13, locknut 12, and bearing 8 is fixed in the bearing support 7.The bottom of rotating shaft 6 is coupled in the coupling 9, and the rotating shaft of generator 11 (the vertical setting) also is connected in the coupling 9.When wind, flywheel rotates, and drives generator 11 by coupling 9 and rotates generating, and electricity power can be powered to the user, simultaneously again can be to battery pack 10 power supplies; When calm, battery pack 10 can provide electric power to the user again.

Embodiment 2: as shown in Figure 4, the lower end of flywheel rotating shaft connects a umbrella gear 14, and it cooperates transmission with the umbrella gear 15 that is coupled to the alternator shaft end, and generator is horizontally disposed with.
