Description

A kind of fan blade and the wind generator device equipped with the blade

Technical field

The utility model is related to wind generator device, the more particularly to improvement of fan blade.

Background technology

Consuming excessively with world resource over nearly 30 years, mankind's available resources are increasingly reduced, and oil price rises steadily, Oil shortage signal takes place frequently all over the world.It is that this mankind needs and due to largely using chemical energy source, natural environment aggravates Want a kind of continuable energy of cleaning.The wind-driven generator that widely used trunnion axis is laid out at this stage.

The number of blade of the wind-driven generator of horizontal axial type layout is generally 1-4 pieces, and the wind-power electricity generation of this kind layout is in wind speed With utilization rate higher when higher, therefore wind-driven generator is quite varied in Large Copacity wind power industry application.But water Flat axle blower fan structure is complex, relatively costly, and threshold wind velocity requirement is higher, and horizontal pneumatic equipment bladess tip-speed ratio is 5-7, Therefore blade can produce larger noise in cutting steam.With the growth of the single-machine capacity of blower fan, blade is more and more long, right Its intensity proposes requirement higher, and this manufacture assembling follow-up to blower fan brings difficulty.

The content of the invention

The purpose of this utility model is the defect for overcoming above-mentioned prior art, there is provided a kind of fan blade.

Above-mentioned purpose is realized by following technical proposals：The fan blade that the utility model is provided, it is characterised in that have The travel(l)ing rest of segmented and the covering being arranged at outside each segmentation, are hinged fixation, and hinged place is provided with use between each segmentation The drive mechanism of angle between segmentation is adjusted, the travel(l)ing rest at least has blade base segment, blade stage casing and blade tip, described Blade base segment is fixed with the rotatable parts of blower fan.

The utility model fan blade also has feature further below：

1st, the drive mechanism is by motor-driven oscillating arm mechanisms.

2nd, the oscillating arm mechanisms are interlock type oscillating arm mechanisms, and the angle that fan blade is respectively segmented is by same interlock type swing arm Mechanism is adjusted.

3rd, the drive mechanism is the oscillating arm mechanisms controlled by separate electrical motor.

Additionally, the utility model also proposed a kind of wind generator device equipped with above-mentioned blade, composition is included:Base Seat, the housing being arranged on pedestal and the rotatable parts for being arranged at case top and 3 fan blades, the base of the fan blade Section is fixed with the rotatable parts, and the motor for driving oscillating arm mechanisms, the rotatable parts are provided with the rotatable parts It is connected with wind power generator rotor, the stator of wind-driven generator is fixed in housing, 3 are provided with the middle part of the housing is used for Accommodate the slot of the blade tip head insertion of fan blade.

The utility model wind-driven generator also has feature further below：

1st, the slot is self-locking slot.

2nd, the angle between the fan blade is 120 °.

Blade of the present utility model is segmented, therefore each section of angle can be adjusted, therefore, set using the type Count windward side of the wind-power electricity generation function of blade effectively to blade under different time, different wind speed and make regulation, Neng Gougao Effect safely controls the wind energy utilization of blower fan.There is more preferable flexibility compared to conventional fan.

The beneficial effects of the utility model are as follows：

1st, blade construction is novel, Discrete control can be carried out, to adapt to the power generation requirements under different wind speed.

2nd, threshold wind velocity is small, control is flexible, can adjust wind energy utilization under different wind conditions.

3rd, sectional-type blade is adjusted using motor control, and every section of blade is connected by pure mechanic structure, easy to control, reliable Property is high.

4th, whole mechanism only has three motors, and remaining realizes that number of motors is few by mechanical structure entirely, controlling party Just, simply.

5th, wind power generation plant small volume, lightweight.

Specific embodiment

The utility model blade of wind-driven generator and wind generator device are said with reference to the accompanying drawings and examples It is bright.

As Figure 1-5, the present embodiment wind generator device composition is included:Pedestal 9, the shell being arranged on pedestal 9 Body 8 and the maincenter console being arranged at the top of housing 8（Rotatable parts）1 and 3 fan blade 6, the angle between fan blade It is 120 °.The travel(l)ing rest that fan blade has segmented and the covering being arranged at outside each segmentation, fixation is hinged between each segmentation, And hinged place is provided with the drive mechanism for angle between regulation segmentation.In the present embodiment, the travel(l)ing rest of blade is three Segmentation, with the blade base segment 3, blade stage casing 4 that are sequentially connected and blade tip 5, blade base segment 3 passes through blade attachment 2 and wind The maincenter console 1 of machine is fixed.Wherein, drive mechanism is that, by motor-driven oscillating arm mechanisms, oscillating arm mechanisms are interlock type swing arm Mechanism, the angle that fan blade is respectively segmented is adjusted by same interlock type oscillating arm mechanisms.Drive mechanism can also be used by independent The oscillating arm mechanisms of motor control.The motor for driving oscillating arm mechanisms is provided with maincenter console 1（It is not drawn into figure）, maincenter Console 1 is connected with wind power generator rotor, and the stator of wind power generator rotor and wind-driven generator is fixed in housing 8, shell The middle part of body 8 is provided with the self-locking slot 7 that 3 blade tip heads for accommodating fan blade are inserted.

The course of work of this wind generator is as follows：

1st, manually device is assembled on air-blower control platform first, can normal work, now state be original state. Begin to use remote control to be issued to control unit to instruct, motor drives the travel(l)ing rest of blade, be in whole device and treat Working condition.Now motor is stopped, and after after the minimum threshold wind velocity that wind speed reaches device, device will be operated. When wind energy utilization higher is needed, mounted blade state can be adjusted such as Fig. 1；When relatively low wind energy utilization is needed, can be such as Fig. 4 Regulation mounted blade state；When needing regulation to other utilization rates, can be adjusted within the device adjustable extent of the two.

When the 2nd, adjusting blade windward side, can be sent to control unit by remote control and instructed, regulation motor voltage is big Small, motor drives travel(l)ing rest, and the blading that the adjustment of the angle and state of support enables to be attached on support is followed It is adjusted, so as to complete the adjustment of blade state.

3rd, sent to control unit by remote control and instructed, blade is drawn in such as Fig. 4, continue adjustment position state, can be with Blade tip insertion self-locking slot is effectively carried out into pinning fixation, it is to avoid draw when because the bad weather such as typhoon causes that blading departs from Play the quick danger fallen.

Of the present utility model creation new is to propose a kind of fan blade of segmented, can carry out leaf by drive device Piece is adjusted, and gives the wind generator device equipped with the blade.Oscillating arm mechanisms are controlled for prior art category, by the skill Art is applied to do not have technical difficulty to the control of blade, and those skilled in the art read the utility model specification and drawings After can realize, even if the utility model does not provide the type selecting of control unit.As for the specific method of control blade, applicant Application for a patent for invention will be separately proposed, the utility model is not disclosed, nonetheless, and without prejudice to the utility model specification Meet open sufficiently requirement.

In addition to the implementation, the utility model can also have other embodiment.All use equivalents or equivalent change The technical scheme to be formed is changed, the protection domain of the utility model requirement is all fallen within.
