Description

A kind of wind power generating set with vertical shaft

Technical field:

The utility model relates to the improvement of wind power generating set with vertical shaft structure.

Background technique:

Existing wind generating unit normally is arranged on the turntable of pylon, and its main structure is that blade pass is crossed speed-changing gear box, braking device links to each other with generator.But have following shortcoming: the speed ratio of speed-changing gear box is bigger, generating frequency instability; The electricity generating device volume is huger and heavy; Safeguard also difficult.

The model utility content:

The utility model is exactly at the problems referred to above, provides a kind of simple in structure, the wind power generating set with vertical shaft that output power is stable.

For achieving the above object, the utility model adopts following technological scheme, the utility model comprises pylon, on the vertical shaft of its structure outline pylon top horizontal fixed have and have main winding, the stator of secondary winding, be provided with permanent magnet in the housing rotor corresponding to the main winding of stator, secondary winding, the housing rotor is outside equipped with fan blade, and the same vertical shaft of housing rotor, the pylon position that contacts is respectively arranged with bearing.

The beneficial effects of the utility model:

1, simple in structure:

Wind generating unit of the present utility model mainly be on the vertical shaft above the pylon, be fixed with have main winding, the stator of secondary winding, be provided with permanent magnet in the housing rotor corresponding to the main winding of stator, secondary winding, the housing rotor is outside equipped with fan blade; Just saved turntable, speed-changing gear box and braking device etc. heavy in the existing wind generating unit, made it simple in structure, compactness;

2, output frequency is stable:

The stator of wind generating unit of the present utility model is provided with the secondary winding corresponding to main winding, can be by the break-make of the coil on the Single-chip Controlling secondary winding, the eddy current that secondary winding is produced increases or reduces, thereby the rotating speed of adjustment housings rotor, guarantee the output frequency of the voltage that main winding produces, make it be stable at 50 hertz, guaranteed that the electric power that wind generating unit of the present utility model produces has the condition that is incorporated into the power networks;

3, need not safeguard:

Housing rotor of the present utility model is at low cruise all the time, and therefore, it is less to wear and tear between the member, can move all the year round and need not safeguard.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is circuit theory diagrams of the present utility model.

Embodiment:

The utility model comprises pylon 13, on the vertical shaft 8 of pylon 13 tops horizontal fixed have and have main winding 4, the stator 6 of secondary winding 3, be provided with permanent magnet 2 in the housing rotor 5 corresponding to the main winding 4 of stator 6, secondary winding 3, housing rotor 5 is outside equipped with fan blade 1, and housing rotor 5 is respectively arranged with bearing 10, bearing 11 with vertical shaft 8, pylon 13 position that contacts.

Vertical shaft 8 can be fixed on the pylon 13 by flange 12; Be convenient to dismounting, maintenance of wind generating unit of the present utility model etc.

Be provided with pillar 9 above vertical shaft 8, fan blade 1 links to each other with pillar 9 by suspension rod 7; Can strengthen the rigidity of fan blade 1 like this.

The output terminal of main winding 4 links to each other through the input end of bleeder circuit 17 with measuring circuit 16, the output terminal of measuring circuit 16 links to each other with the input end of single-chip microcomputer 15, the

output terminal

1,2 of single-chip microcomputer 15 ... n through triode VT1, VT2 ... VT2n with relay J 1, J2 ... the coil of J2n links to each other, relay J 1, J2 ... the contact of J2n links to each other with the coil on the secondary winding 3 14.

Below in conjunction with a description of drawings course of action of the present utility model:

When the moving fan blade 1 of the present utility model of wind, fan blade 1 rotates the permanent magnets 2 that drive in the housing rotor 5 and rotates, and makes the coil 14 of main winding 4 do relative cutting magnetic induction line motion, and the coil 14 of main winding 4 produces electric currents, generates electricity; Meanwhile, the coil 14 of secondary winding 3 is also being done relative cutting magnetic induction line motion, can control the break-make of the coil 14 of secondary winding 3 by single-chip microcomputer 15, the eddy current that secondary winding 3 is produced increases or reduces, thereby the rotating speed of adjustment housings rotor 5, guarantee the output frequency of the voltage that main winding 4 produces, make it be stable at 50 hertz, guaranteed that the electric power that wind generating unit of the present utility model produces has the condition that is incorporated into the power networks.

In the process of normal power generation, measuring circuit 16 sends the output frequency of the voltage that the main winding 4 that records produces to single-chip microcomputer 15, described measuring circuit 16 can be selected 7753 chips for use, described single-chip microcomputer 15 can be selected the 89S52 chip for use, single-chip microcomputer 15 carries out the analogue signal that receives to judge, handle after the A/D conversion, if the output frequency of voltage equals 50 hertz, then single-chip microcomputer 15 is failure to actuate; If the output frequency of voltage is less than 50 hertz, by the control of single-chip microcomputer 15 make a pair of coil that is centrosymmetric 14 on the secondary winding 3 relay J 1, J2 ... the contact of J2n disconnects, thereby reduce the resistance that eddy current effect produced, accelerated the rotational velocity of housing rotor 5, the output frequency of the voltage that promptly raise; If the output frequency of voltage is greater than 50 hertz, by the control of single-chip microcomputer 15 make a pair of coil that is centrosymmetric 14 on the secondary winding 3 relay J 1, J2 ... the contact adhesive of J2n, thereby increase the resistance that eddy current effect produced, the slowed down rotational velocity of housing rotor 5 has promptly reduced the output frequency of voltage.So repeated measurement, judgement, processing are to reach the effect of constant frequency.
