Description

A kind of small off-grid wind power generation system
Technical field
The utility model relates to a kind of small off-grid wind power generation system, belongs to technical field of wind power generation.
Background technique
Along with the fast development of new energy industry, country constantly advocates the life of environmental protection low-carbon (LC), installed capacity of wind-driven power constantly rises in China, the area such as the Northwest, the Inner Mongol, southeastern coast that wind resource enriches is covered by wind-power electricity generation gradually, the power level of Wind turbines constantly rises, from hundreds of kilowatt to a few megawatt.The application area of wind-power electricity generation is more and more wider simultaneously, and has been amplified out gradually from net type unit by the grid type of extensive use.Good development prospect is had in fields such as heating, desalination of sea water, isolated island illuminations from net type unit.Application from net type unit can be mated for different loadtypes.
But, existing comparatively large at power from net type unit, be only applicable to the area that wind energy is comparatively concentrated, in wind-force and the more area of wind vector, just not too applicable.
Summary of the invention
The technical problems to be solved in the utility model is, not enough for prior art, proposes the wind-power generating system that a kind of structure is simple, have turning function.
The utility model is the technological scheme solving the problems of the technologies described above proposition: a kind of small off-grid wind power generation system, comprises pylon and wind generating unit; Described wind generating unit comprises the blade, speed reducer and the generator that are connected successively by traditional axle; Described pylon top is fixed with a vertical axle; Described axle is provided with bearing; Described wind generating unit is fixed on described bearing; Described generator is arranged on the side of described bearing, and described blade and speed reducer are arranged on the opposite side of described bearing; The output terminal of described generator is connected with voltage stabilizer, and the output terminal of described voltage stabilizer is connected with lithium cell group, and electric energy is exported by inverter by described lithium cell group.
Small off-grid wind power generation system of the present utility model, wherein wind generating unit can rotate in the horizontal direction, to adapt to the change of wind direction.During in order to prevent wind speed higher, the rotational speed of wind generating unit is too fast, is placed in by generator on feathering axis, increases rotary inertia, and the rotational speed effectively reducing self prevents from damaging.And be directly provided with lithium cell group and charging, inverter, like this, outgoing cable is civil power, easy to use.
Such scheme further improves and is, described axle is hollow structure, wherein can hold cable, to facilitate wiring.
Such scheme further improves and is, described blade is less than the distance of described generator to described bearing to the distance of described bearing; Described generator casing is provided with tuning tail vane, is beneficial to wind generating unit adjustment direction further.
Such scheme further improves and is, described voltage stabilizer, lithium cell group and inverter are placed in described generator front.Rotary inertia can be increased further like this.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model preferred embodiment structural representation.
Number in the figure is schematically as follows: 1-pylon, 2-axle, 3-bearing, 4-blade, 5-speed reducer, 6-generator, 7-tuning tail vane, 8-lithium cell group.
Embodiment
Embodiment
The small off-grid wind power generation system of the present embodiment, as shown in Figure 1, comprise pylon 1 and on pylon 1 top, the wind generating unit that can horizontally rotate; Wind generating unit comprises the blade 4, speed reducer 5 and the generator 6 that are connected in turn with transmission shaft; Pylon 1 top is fixed with a vertical axle 2; Axle 2 is provided with bearing 3; Namely wind generating unit is fixed on bearing 3; Generator 6 is arranged on the side of bearing 3, and blade 4 and speed reducer 5 are arranged on the opposite side of bearing 3; The output terminal of generator 6 is connected with voltage stabilizer, and the output terminal of voltage stabilizer is connected with lithium cell group 8, and electric energy is exported by inverter by lithium cell group 8.
Voltage stabilizer, inverter and lithium cell group 8 combine, and are arranged on the front of generator 6, and what increase wind generating unit further horizontally rotates inertia.
Axle 2 is hollow structures, wherein accommodates the output cable of inverter 6, like this, and can the wiring easily in below.
As shown in fig. 1, blade 4 is less than the distance of generator 6 to bearing 3 to the distance of bearing 3, and to conduct oneself with dignity larger feature in conjunction with generator 6, like this, the rotary inertia of wind generating unit is very large, can effectively prevent from rotating too fast.The shell of simultaneously generator 6 is provided with tuning tail vane 7, the feature that the cantilever in conjunction with generator 6 self is longer, can ensures that blade 4 is all the time towards direction of the wind comes from.
The small off-grid wind power generation system of the present embodiment, structure is simple, is suitable for low-power generator, is more suitable for being used in remote districts or rural area, provides the electricity consumptions such as illumination, heating from net.Especially, the output cable of the present embodiment directly exports line voltage, can extremely be convenient to use.
The utility model is not limited to above-described embodiment.All employings are equal to the technological scheme of replacing and being formed, and all drop in the protection domain of the utility model requirement.
