Abstract
The utility model relates to a wind generator, in particular to a vertical shaft type wind generator with a windshield, which consists of a generator, a wind direction rudder, a rotating shaft, a bearing, a rotary supporting seat and a blade, wherein, the rotating shaft is mounted on the generator, the blade and the windshield are fixedly mounted on the rotating shaft, and the wind direction rudder is fixedly installed on the windshield. Therefore, regardless of changes in the wind direction, the wind direction rudder can adjust the box body of the windshield according to wind direction to the direction opposite to the wind direction, thereby eliminating the resistance facing the blade in operation, and solving the problem that the prior vertical shaft type generator's blade, which not only does positive work under a lift force but also dose negative work under a resistance when in operation, affects the work efficiency of the wind generator. With the advantages of simple structure and easy manufacture, the utility model can enable the wind generator to work with the maximum work efficiency, and therefore is particularly suitable for the vertical shaft type wind generator.
Description
Technical field:
The utility model relates to a kind of wind-driven generator, particularly a kind of vertical shaft type wind-driven generator that has wind shield.
Background technique:
Along with the minimizing day by day of non-renewable energy resources such as coal, oil, seek new this problem of alternative energy source and caused people's great attention.Just more and more general to the use of solar energy, wind energy, water energy equal energy source now as people, to gradually reduce the consumption of non-renewable energy resources.Wind-power electricity generation is exactly to drive generator operation by natural wind energy and implements generating, and its great advantage is environmental protection, and is pollution-free, inexhaustible, also can not resemble harmful gas and dusts such as producing carbon monoxide the thermal power generation.The working principle of wind-driven generator all is to promote blade by wind energy to rotate, and is driven generator amature work and is produced electric power by blade again.Therefore, the angle of wind direction and blade just becomes the critical problem of wind turbine power generation amount size, and augular offset will have influence on the working efficiency of wind-driven generator too greatly.Existing wind-driven generator mainly is divided into horizontal axis wind-driven generator and vertical shaft type wind-driven generator, vertical shaft type wind-driven generator particularly, during work, what blade was subjected in a side of transmission shaft is lift, promptly do positive work, what be subjected at the opposite side of transmission shaft is resistance, promptly does negative work, thereby has influenced the working efficiency (referring to accompanying drawing 1) of wind-driven generator to a great extent.
Summary of the invention:
The purpose of this utility model is: a kind of angle that can adjust automatically with wind direction is provided, and can eliminates the resistance that blade is subjected to when work, thereby improve the working efficiency of wind-driven generator; And the vertical shaft type wind-driven generator that has wind shield simple in structure, easy to manufacture.
The utility model is to realize above-mentioned purpose by following technical solution:
This vertical shaft type wind-driven generator that has wind shield is made of generator, wind direction rudder, running shaft, bearing, rotation supporting base and blade, it is characterized in that: running shaft is housed on the generator, be fixed with blade on the running shaft, and by bearing and the rotation supporting base one wind shield is housed, half of blade places in the wind shield, and described wind shield one side is fixed with the wind direction rudder.
Described wind shield is the casing of a semicircle, and the wind direction rudder that installs on it and the opening of wind shield are on same plane.
The utility model beneficial effect compared with prior art is:
The utility model is equipped with a wind shield on blade, and a wind direction rudder is installed on wind shield, how no matter wind direction conversion, the wind direction rudder can both according to wind direction with the opening surface of wind shield adjust to wind direction in same direction, and can eliminate the resistance that blade is subjected to when work, thereby improve the wind-driven generator working efficiency.Solved existing vertical shaft type wind-driven generator blade and the time both be subjected to lift in work and do positive work, be subjected to resistance again and do negative work, thereby influence the problem of wind-driven generator working efficiency, made the working efficiency of vertical shaft type wind-driven generator be able to the performance of maximum.
Description of drawings:
Stressing conditions schematic representation when Fig. 1 works for existing vertical shaft type wind-driven generator blade;
Fig. 2 is the structural representation that has the vertical shaft type wind-driven generator of wind shield;
Fig. 3 is that the position of wind shield and wind direction rudder concerns the plan structure schematic representation.
Among the figure: 1, wind direction rudder, 2, running shaft, 3, generator, 4, blade, 5, bearing, 6, the rotation supporting base, 7, wind shield.
Embodiment:
This vertical shaft type wind-driven generator that has wind shield is by wind direction rudder 1, running shaft 2, generator 3, blade 4, bearing 5, and rotation supporting base 6 and wind shield 7 constitute, and running shaft 2 is housed on the generator 3, are fixed with blade 4 on the running shaft 2.Wind shield 7 is movably arranged on the running shaft 2 by bearing 5 and rotation supporting base 6, and wind shield 7 is a ringent semicircle casing.Be fixed with wind direction rudder 1 on the wind shield 7, the opening surface of wind direction rudder 1 and wind shield 7 on same plane, with the opening surface that guarantees wind shield 7 and wind direction rudder 1 all the time with wind direction at same direction (referring to accompanying drawing 2-3).
Working procedure of the present utility model is identical with existing wind-driven generator, but owing on blade 4, be set with the wind shield 7 of half round box by running shaft 2, half blade of blade 4 is rotated in wind shield 7, eliminated the resistance that blade 4 is subjected to effectively when work, its resistance is eliminated by the wind shield 7 of semicircle casing and is disintegrated, thereby improve the working efficiency of wind-driven generator, make the wind-power electricity generation function give play to maximal efficiency.
