Abstract
The utility model discloses a novel generator rotor. The generator rotor comprises four rotor blades, wherein an angle formed by adjacent rotor blades is 90 degrees, each of the rotor blades comprises a rib belt located on the horizontal plane, and one end of the rib belt is provided with two S-shaped blade faces which are symmetrical along the horizontal plane. The novel generator rotor can meet the wind from any direction to rotate to generate electricity; even if the wind is small, the generator rotor can rotate to generate electricity, so that working efficiency of a wind driven generator is greatly improved; and the S-shaped blade faces can better adapt to the wind from each direction.
Description
Technical field
The utility model relates to a kind of new-generation machine rotor, is specifically related to a kind of rotor of horizontally rotating type wind generating unit.
Background technique
Along with continuous development economic and society, the energy, environment and information become three big themes of 21 century development in science and technology, and people strengthen day by day to demand and the attention degree of cleaning, renewable new energy.Wind-power electricity generation is one of reproducible cleaning new energy, because it has safety, reliable, low, the easy to use cleaning again of cost, therefore the characteristics of environmental protection, obtained people's great attention in the last few years.
The blade of conventional use wind-driven generator is vertical the placement, structurally has a tailplane and the rolling bearing that can make the 360 degree rotations of electric generator casing level.These two matching used functions of parts mainly are for the blade that makes wind-driven generator caters to wind direction, thereby make the blade rotation drive electric power generation.But under many circumstances, for example: the too small or rolling bearing of wind-force is corroded, gets rusty etc., and tailplane is inoperative, and the rolling bearing rotational resistance is excessive or can not rotate at all.Therefore at this moment blade can not cater to wind direction, can not rotate or rotating speed slows down, thereby influence the generating efficiency of motor greatly, or send out to go out electricity at all.Investigation at a wind-driven generator test site shows: 50 of the total wind-driven generators in this test site, and use the blade that has 18 generators after 3 years not rotate, spoilage is up to 36%, and its subject matter all is that the inefficacy by above-mentioned two parts causes.
The model utility content
The purpose of this utility model is to provide a kind of new-generation machine rotor, it is used for the horizontally rotating type wind generating machine, do not need conventional wind-force electrical machinery to be used for seeking the tailplane of wind direction and being used for driving the secondary rolling bearing that electric generator casing level 360 degree rotate, not only reduce production cost about 30%, and reduced owing to use energy loss that this two parts bring or quit work owing to its damage causes generator, simultaneously because the blade of horizontal positioned has the function of empennage concurrently, can cater to the next wind of any direction in 360 degree and rotary electrification, also can rotary electrification even wind-force is less, thus the working efficiency of wind-driven generator improved greatly.
For achieving the above object, the technical solution of the utility model is a kind of new-generation machine rotor of design, comprise that adjacent angle is four rotor blades of 90 degree, rotor blade comprises a muscle band that is positioned at horizontal plane, one end of muscle band is provided with two blade faces of symmetry with respect to the horizontal plane, and two blade faces are S-shaped.
Preferably, two blade face angles of described rotor blade are spent more than or equal to 70, and are less than or equal to 100 degree.
Preferably, two of described rotor blade blade faces are provided with some grooves.
Preferably, described groove is uniform on the blade face.
Preferably, two of described rotor blade blade faces are provided with some raised lines.
Preferably, described raised line is uniform on the blade face.
The S-shaped wind direction that can adapt to all directions more in blade face.
Advantage of the present utility model and beneficial effect are: a kind of new-generation machine rotor be provided, can cater to any direction is come in 360 degree wind and rotary electrification, also can rotary electrification even wind-force is less, thus improved the working efficiency of wind-driven generator greatly.
(1) blade (generally having three) of conventional use wind-driven generator is vertical the placement, and electric generator casing is horizontal positioned.And the wind turbine power generation structure of the utility model preparation is just in time opposite, and blade is horizontal positioned, and casing is vertical placement.The conventional wind-driven generator that uses is to lean on tailplane and the synergy of two parts of rolling bearing that horizontally rotate to make generator cater to wind direction, thereby makes blade rotate to drive generator for electricity generation.And wind-driven generator of the present utility model has saved this two parts, because the blade of horizontal positioned has the function of empennage concurrently, can cater to any direction is come in 360 degree wind and rotary electrification, also can rotary electrification even wind-force is less, thus improved the working efficiency of wind-driven generator greatly.
(2) because the utility model does not need tailplane and the rolling bearing that horizontally rotates, it is about 30% not only to reduce the production cost, and has reduced owing to use energy loss that these two parts bring or quit work owing to its damage causes generator.
(3) because the shape of the prepared blade of wind-driven generator of this model utility is four symmetrical horizontal positioned.Features simple structure is easy to preparation, the rotation efficiency height, cost of production is low, can be at wind-force more weak and under any wind direction condition rotary electrification.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The concrete technological scheme of implementing of the utility model is:
The wind power plant that matches with this new-generation machine rotor comprises: perpendicular to the support on ground, and body 4, transmission shaft, sealing bulb 3, wind rotor blade link rod 2.
This new-generation machine rotor, comprise adjacent angle be 90 the degree four rotor blades 1, rotor blade 1 comprises a muscle band 5 that is positioned at horizontal plane, an end of muscle band 5 be provided with two with respect to the horizontal plane the symmetry 6, two blade faces 6, blade face S-shaped.Two blade faces 6 of described rotor blade 1 are provided with some grooves, and described groove is uniform on blade face 6.
