The utility model provides a novel wind-driven generator rotor which adopts a mechanical transmission device and can control the wind forced area of a retractable umbrella blade, increase the resistance difference, and improve the rotor rotation speed under the same condition. The device comprises a rotation shaft and a framework utilizing the rotation shaft as a rotation center. The novel wind-driven generator rotor is characterized in that transmission devices are symmetrically installed with the rotation shaft serving as the center on the framework, the transmission devices are connected with the umbrella blade, and the umbrella blade is a retractable structure. The wind-driven generator rotor can be used for driving the umbrella blade to contract and expand through the transmission mechanism, controls the factor that the cross sections are different when the umbrella blade bears force on the frontal area and the back surface, increases the resistance difference, and improves the rotor rotation speed, thereby improving the power generation power and efficiency.

Description

A kind of wind power generator rotor

Technical field

The utility model relates to a kind of wind power plant, refers more particularly to the rotor on the wind-driven generator.

Background technique

Wind-power electricity generation is as a kind of more and more ripe pollution-free generation technology, in reality, use more and more widely, the principle of wind-power electricity generation, be to utilize wind-force to drive the aero-generator rotor blade rotation, see through the speed lifting of booster engine again with rotation, impel generator for electricity generation, according to present wind generating technology, approximately be the gentle breeze speed (degree of gentle breeze) of three meters of per seconds, just can begin generating, rotor is as the key position on the wind-driven generator, and its structure Design is directly connected to the efficient and the power of wind-power electricity generation.

Traditional wind power generator rotor is made up of blade and rotating shaft, blade generally is designed to streamlined, forms resistance difference by the difference of controlling every blade face surface low line, drives rotor rotation then, under the situation of wind-force constant magnitude, resistance difference is invariable.In order to improve the efficient of wind power utilization, need design a kind of new rotor blade, the area of stress surface when being subjected to power by increase, the area that reduces stress surface when being subjected to resistance further increases resistance difference, reach the rotating speed that improves rotor, increase the purpose of generator power.

Summary of the invention

Technical problem to be solved in the utility model is to the inadequate situation of Wind Power Utilization at present wind-driven generator, design a kind of novel rotor, change the area that is subjected to the wind-force face according to different situations, increase resistance difference, under equal conditions improve the rotating speed of rotor, thereby improve the generating efficiency and the power of wind-driven generator.

The technical solution of the utility model is: a kind of wind power generator rotor, include rotating shaft and be the skeleton of rotating center, it is characterized in that: for the center symmetry transmission device is housed with the rotating shaft on the skeleton with the rotating shaft, transmission device is connected with the umbrella leaf, and the umbrella leaf is collapsible structure.

According to a kind of wind power generator rotor that the utility model provides, the umbrella leaf is that metal or plastics are made, by top, below, the side is formed, and wherein the side is that three rectangle bent plates are formed by connecting.

A kind of wind power generator rotor that provides according to the utility model, transmission device includes fore shell and back cover, both are plugged on together, and surround cavity, the vertical cylindrical gears dish of main shaft is housed in the cavity, and at the coaxial two ends of cylindrical gears dish a pair of cone gear is housed respectively, a pair of cone gear respectively with the cone gear engagement of two horizontal axis, and two disks are housed at two other ends of horizontal axis.

According to a kind of wind power generator rotor that the utility model provides, fore shell is " recessed " font structure, and front screen is equipped with in its bottom surface, front screen and umbrella leaf welding or glued.

According to a kind of wind power generator rotor that the utility model provides, back cover also is " recessed " font structure, and backboard is equipped with in its bottom surface, its outstanding end face and skeleton welding or glued, and its inboard is a rack structure.

According to a kind of wind power generator rotor that the utility model provides, cylindrical gears dish and back cover be inner mesh on one side.

A kind of wind power generator rotor according to the utility model provides is wound with steel wire on two disks, and steel wire is connected respectively to the two boards up and down of the side of umbrella leaf.

The beneficial effects of the utility model are: drive the umbrella leaf by driving mechanism and shrink and diastole, be controlled at the umbrella leaf positive when stressed sectional area when stressed with the back side different, increased resistance difference, improved the rotating speed of rotor, thereby improved the power and the efficient of generating.

Description of drawings

Fig. 1 is the utility model device overall structure figure

Fig. 2 is the utility model device skeleton and turning shaft structure figure

Fig. 3 is the utility model device transmission device local structure figure

In figure: 1 umbrella leaf, 2 rotating shafts, 3 skeletons, 4 transmission devices, 5 back covers, 6 fore shells, 7 backboards, 8 front screens, 9 cylindrical gears dishes, 10 vertical conical gears, 11 horizontal circle bevel gears, 12 disks, 13 steel wires

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figures 2 and 3, front screen 8 and fore shell 6 are fixedlyed connected by screw, backboard 7 also is to fixedly connected by screw with back cover 5, front screen 8 is also fixedlyed connected with umbrella leaf 1, back cover 5 is also fixedlyed connected with skeleton 3, when wind promotes umbrella leaf 1, just give 8 one thrusts of front screen or pulling force, and then drive fore shell 6 and back cover 5 relatively moves.

As shown in Figure 3 in transmission device, cylindrical gears dish 9 is installed in the cavity that fore shell 6 and back cover 5 surround, and adopt the pinion and-rack engagement with one side of back cover 5 is inboard, at cylindrical gears dish 9 coaxial two ends a pair of vertical conical gear 10 is housed respectively, a pair of vertical conical gear 10 respectively with horizontal circle bevel gear 11 engagement of two horizontal axis, and two disks 12 are housed respectively at two other ends of horizontal axis.When umbrella leaf 1 turns to opening back to wind direction, fore shell 6 movement directions are near skeleton 3 directions, because the meshing relation of gear rack, cylindrical gears dish 9 will rotate, the disk 12 of horizontal axis is passed in this rotation by the engagement of two bevel gears, steel wire 13 on the disk 12 is along with the rotation of disk 12 is drawn in, and pulling umbrella leaf 1 also shrinks, and has realized the minimizing that is subjected to the wind-force area of umbrella leaf 1 with this.

When umbrella leaf 1 turned over 180 °, fore shell 6 movement directions were opposite, and the steel wire 13 on the disk 12 is relaxation state, and this moment, umbrella leaf 1 opening was subjected to the influence of wind-force, can strut automatically, can reach with this to increase the effect that is subjected to the wind-force area.

So two umbrella leaves 1 of symmetry are in rotating process, and constantly repeated transformation and facingd the wind and leeward direction, and umbrella leaf 1 also can constantly open thereupon and shrink in turn, has improved the rotational speed of rotor, and improved the efficient and the power of generating.

More than under be preferred embodiment of the present utility model only, be not limited to the utility model, all any modifications of within the utility model spirit and principle, being made, be equal to replacement and improvement etc., all be contained within the protection domain of the present utility model.
