Background

At present, energy sources become important resources supporting the development of national economy, many energy sources are non-renewable, and the exploitation and use of the energy sources are often accompanied by the change of geological conditions and the generation of environmental pollution, such as: petroleum, natural gas, coal and the like directly influence the human living environment and the sustainable development of social economy. Therefore, the search and utilization of inexhaustible green energy is the subject of research in various countries in the world. At present, the more commonly used green energy sources comprise water energy, solar energy, wind energy and the like, and the energy sources are precious resources provided by the nature and are most suitable for the health of human beings. These energy sources have not been widely used so far, and are not influenced by the limitations of natural conditions and manufacturing costs. Such as: hydroelectric power generation is performed by using rivers with sufficient water sources and large water level drops, the construction difficulty is high, the construction period is long, the power station is far away from the use land, a power grid needs to be erected for power transmission, and the investment is high. Wind power generation needs to be arranged in a large scale, is usually built in places with wind roads on mountain girders, has certain selection on natural geographical conditions, is usually far away from cities, also needs to remotely transmit electric power, and has higher construction cost. Neither of the above two energy sources can be directly used at home. Some uses of solar energy have been directed to homes. Such as: solar water heaters, solar panels, and the like. However, the energy provided by the solar energy device is limited, if the lighting area of the device needs to be enlarged to improve the power, the solar energy device is very convenient for urban residences, the service life of the solar energy device is not long, and the solar energy device needs to be replaced and updated regularly. Northern wind power resources are abundant, good natural conditions are provided for the utilization of wind energy, but the northern wind power resources are still rare as small wind energy devices applied to families or small and medium enterprises.

Disclosure of Invention

The utility model aims at providing a higher device that utilizes wind energy power generation that is suitable for family to use of wind energy utilization ratio.

The technical scheme of the utility model is that: including rotor, pivot and support, the rotor dress is in the pivot, pivot and support normal running fit, the rotor comprises at least three impeller, and every impeller is the symmetrical structure who constitutes by last blade and lower blade back to back, going up blade and lower blade and being the tubular structure, the impeller revolutes a circumference array on same horizontal plane, and the inner of impeller is close to the pivot, goes up the outer end cross-section of blade and lower blade and is the curved surface, rotor and pivot fixed coordination.

The curved surfaces of the outer ends of the upper blade and the lower blade are spiral.

The inner ends of the upper blade and the lower blade are fixedly connected with a connecting sleeve into a whole, and the connecting sleeve is fixedly connected with the rotating shaft into a whole.

At least one rotor can be mounted on the rotating shaft.

The upper end of the rotating shaft is arranged on a bearing at the top of the bracket, and the lower end of the rotating shaft is arranged on a power generation device of the bracket bottom plate.

The connecting sleeve is divided into two halves and is fastened into a whole through a bolt.

The connecting sleeve is tightly fixed with the rotating shaft into a whole through key slot matching.

The utility model discloses a by two symmetrical structure back to back of last blade and lower blade, make the compact structure of every impeller, wind energy utilization further improves. Because the upper blade and the lower blade are both in tubular structures, the cross sections of the outer ends of the upper blade and the lower blade are curved surfaces, the wind force borne by the wind-receiving surfaces of the upper blade and the lower blade is always in an unbalanced loading state, and the rotor can be pushed to rotate by slight wind. Each impeller is arrayed on the same horizontal plane around the circumference of the rotating shaft, and wind coming from different directions can blow the rotor to rotate. When the wind blows to the rotor, the inner walls of the upper blade and the lower blade face the wind, and the inner walls are concave curved surfaces, so that the wind resistance is large, and the wind energy can be effectively utilized to push the impeller to rotate. When wind blows to the impeller, part of the wind leaks from the two ends of the impeller, and the wind leaking to the rotating shaft direction directly acts on the inner walls of the upper blades and the lower blades of the adjacent impellers to push the adjacent impellers to rotate, so that the utilization rate of wind energy is further improved. Meanwhile, when the back surfaces of the upper blade and the lower blade face the wind, the back surfaces are convex curved surfaces, so that the wind resistance is small, and the reverse thrust to the rotor is reduced. Therefore, the rotor can be pushed to rotate to do work by only small wind power, and the wind power generator is very suitable for families and places with small power consumption.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and examples, which should not be construed as limiting the invention in any way. Fig. 1 shows, the utility model discloses a rotor, pivot 4 and support 5, the rotor dress is on pivot 4,

pivot

4 and 5 normal running fit of support, and the rotor comprises at least three impeller. As shown in fig. 2 and 3, each impeller is a symmetrical structure formed by an upper blade 1 and a lower blade 2 back to back, the upper blade 1 and the lower blade 2 are both of a bent tubular structure, each impeller is circumferentially arrayed on the same horizontal plane around a rotating shaft 4, the inner end of each impeller is close to the rotating shaft 4, and the sections of the outer ends of the upper blade 1 and the lower blade 2 are curved surfaces. The rotor is fixedly matched with the rotating shaft 4. In this embodiment, the curved surfaces of the outer ends of the upper blade 1 and the lower blade 2 are preferably spiral, so that the upper blade 1 and the lower blade 2 are formed in an asymmetric structure, and materials are saved. For more reliable installation, the inner ends of the upper blade 1 and the lower blade 2 are welded or riveted with the connecting sleeve 3 into a whole, and the connecting sleeve 3 is fixedly connected with the rotating shaft 4 into a whole through key slot matching. The connecting sleeve 3 can be divided into two halves and is fastened into a whole through bolts. As shown in figure 1, the upper end of the rotating shaft 4 is arranged on a bearing at the top of the bracket 5, and the lower end of the rotating shaft 4 is arranged on a power generation device 6 at the bottom plate of the bracket 5. To increase the power, a plurality of rotors may be mounted on the shaft 4. The power generation device 6 is the prior art, and the selection, installation and use of the power generation device are all mastered by common technicians of the same group, and are not described herein again.

Because the rotor is in an asymmetric structure in the vertical, left-right and front-back directions, when the rotor encounters small wind, the stress of the rotor is unbalanced, and the rotor is pushed to rotate efficiently. When the incoming wind blows on the inner walls of the upper blade 1 and the lower blade 2, the inner walls are of concave structures, so that the wind leakage is less, the wind resistance is higher, the wind energy utilization rate is higher, and the rotor is directly pushed to rotate. Meanwhile, a part of the wind blowing to the inner walls of the upper blade 1 and the lower blade 2 flows out towards the rotating shaft 4, the flowing-out wind just acts on the inner walls of the adjacent upper blade 1 and the adjacent lower blade 2, the rotor is directly pushed to rotate, and the utilization rate of wind energy is high. Under the continuous action of wind power, part of the wind power directly acts on the upper blade 1 and the lower blade 2 to do work, and the wind which flows out from the upper blade 1 and the lower blade 2 and just acts on the inner walls of the adjacent upper blade 1 and the lower blade 2 is continuously transmitted to the next adjacent upper blade 1 and the next adjacent lower blade 2, so that the rotor rapidly rotates to do work. When the incoming wind blows on the inner walls of the upper blades 1 and the lower blades 2, a part of the incoming wind blows on the outer walls, namely the back surfaces, of the adjacent upper blades 1 and the lower blades 2, and the back surfaces are convex curved surfaces, so that the wind resistance is small, and the reverse thrust to the rotor is reduced. Because the back surfaces of the upper blade 1 and the lower blade 2 are far less than the front surfaces, namely the inner walls, the rotor is stressed to rotate to do work.
