Abstract
The utility model is related to a kind of without yaw wind power generating set, including machine tower seat, generator, alternator shaft and fan blade, the connection that the fan blade passes through the alternator shaft and the generator, one end end of the generator far from the fan blade is connect by vertically disposed rotary shaft with the machine tower seat, and the generator can be around the vertically disposed rotary shaft 360 degree rotation.The utility model have it is simple in structure, without adding yaw system or fixed empennage, low cost, the advantage that failure rate is low and wind energy utilization is high.
Description
Technical field
The utility model belongs to technical field of generators, more specifically to a kind of without yaw wind power generating set.
Background technology
Current commercialized wind-driven generator can be divided into horizontal axial type and perpendicular axis type, wind turbine in the market, horizontal axial type
It occupies the majority, but its blade surfaces of revolution must be perpendicular to the wind direction that becomes a mandarin, so must have the function to positive wind direction, large fan uses
Yaw control system, and small-sized fan then has tail structure more.Trunnion axis wind turbine is generally arranged at that wind speed is higher, wind direction is stablized
Area, location condition is about as follows：1, wind field is excellent (wind speed is fixed in 6m/s or more and wind direction).2, antenna height is enough
(general recommendations in 10m or more, depending on position).3, site weather is without veil.
These above-mentioned wind power generating sets with yaw system have two big disadvantages；One is when because of change of the wind, act on
There are the time difference, automatic yaw system also has error (turbulent flow, fan blade disturbance) for the power of fan blade and the active force of yaw system.This just makes
Wind turbine shaking is excessive, affects the normal work of motor, causes to impact to active yawing system, be easily damaged.(through investigation, wind
The failure of machine is mainly gearbox, followed by yaw system, and the failure rate of yaw system is up to 3/the last 1)；The second is this set
Meter makes fan blade close to tower body.It is easy to happen collision when change of the wind, therefore blade is required high.Existing fan blade, is all designed
At pointed, and exactly outer ring torque is bigger, this pointed design, greatly limits the utilization rate of wind-force.
Utility model content
Problem to be solved in the utility model is, provide it is a kind of simple in structure, without adding yaw system or fixation
Empennage, low cost, failure rate are low without yaw wind power generating set.
In order to solve the above-mentioned technical problem, the utility model provides a kind of without yaw wind power generating set comprising machine
Tower seat, generator, alternator shaft and fan blade, the fan blade pass through the connection of the alternator shaft and the generator, institute
It states one end end of the generator far from the fan blade to connect with the machine tower seat by vertically disposed rotary shaft, the generator
It can be around the vertically disposed rotary shaft 360 degree rotation.
Implement it is provided by the utility model it is a kind of without yaw wind power generating set, compared with prior art, have it is as follows
Advantageous effect：
The utility model by fan blade and the entire center of gravity of generator move to pivot point (be connected to generator and machine tower seat it
Between engine base rotary shaft) side, formed be similar to conventional small trunnion axis wind turbine be obtain maximal wind-energy be arranged fixation empennage
Structure can turn an angle according to wind-force direction-adaptive, make wind-force direction perpendicular to the level of the surfaces of revolution of fan blade
Line.As it can be seen that the utility model has the advantages of simple structure, without adding yaw system, low cost, failure rate is low, and most for fan blade
Big wind power utilization design creates condition.
Description of the drawings
In order to illustrate more clearly of the technical solution of the utility model embodiment, the attached drawing of embodiment will be made below simple
Ground introduction.
Fig. 1 is a kind of front view without yaw wind power generating set provided by the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the preferred embodiment of the utility model, a kind of without yaw wind power generating set comprising machine tower seat
1, generator 2, alternator shaft 3 and fan blade 4, the fan blade 4 by the connection of the alternator shaft 3 and the generator 2,
By vertically disposed rotary shaft 5, (rotary shaft 5 is hollow shaft, is for one end end of the generator 2 far from the fan blade 4
There are channels for electric appliance circuits) it is connect with the machine tower seat 1, the generator 2 can be rotated around the vertically disposed rotary shaft 5
360 degree.Fan blade 4 and 2 entire center of gravity of generator are moved to pivot point and (are connected to generator 2 and machine tower seat 1 by the utility model
Between engine base rotary shaft 5) side, it is to obtain the fixed empennage of maximal wind-energy setting to be formed and be similar to conventional small trunnion axis wind turbine
Structure, can be turned an angle according to wind-force direction-adaptive, make wind-force direction perpendicular to the water of the surfaces of revolution of fan blade 4
Horizontal line.As it can be seen that the utility model has the advantages of simple structure, without adding yaw system, low cost, failure rate is low, and is fan blade
Maximum wind power creates condition using design.
The essence of the utility model, be generator stand rotary shaft and blade suitable distance without yaw system, be based on
This principle and the design of other patterns made belong to the protection category of this patent.
