Abstract
The utility model provides a passively-windward horizontal shaft wind-driven generator. The utility model comprises a wind wheel, a generator and a windward revolution shaft, wherein the wind wheel is fixedly arranged on a rotary shaft of the generator and the generator is connected with the windward revolution shaft through a revolution bearing. The rotary shaft of the generator is in off-set arrangement corresponding to the windward revolution shaft. The length of a common perpendicular between a center line of the rotary shaft of the generator and a center line of the windward revolution shaft is the off-set quantity X. The utility model has the advantages that the structure is simple, compact, reliable and stable, the applicable power range of the generator is large and the input cost of the device is low.
Description
Technical field
The utility model relates to the horizontal axis wind-driven generator technical field, specifically is meant a kind of passive horizontal axis wind-driven generator to wind.
Background technique
At present, large and medium-sized horizontal axis wind-driven generator adopts the General layout Plan of the active of " wind direction detection-automatically controlled driving " to wind, but for small-sized horizontal axis wind-driven generator, adopt the General layout Plan of active to wind, its Economy is infeasible, therefore, current small-sized horizontal axis wind-driven generator is passive upwind horizontal axis wind-driven generator type to wind, adopts by passive General layout Plans to wind of mechanism such as tail vane, tail wheels.
Passive upwind horizontal axis wind-driven generator to wind exists following shortcoming: complex structure, tail vane, tail wheel size are big, also can influence the stability and the reliability of unit operation, are not suitable for more powerful type more than the multikilowatt.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple and compact for structure, and reliable and stable passive horizontal axis wind-driven generator to wind.
The purpose of this utility model realizes by following proposal: this passive horizontal axis wind-driven generator to wind, comprise wind wheel, generator, to the wind turning axle, described wind wheel is fixedly mounted on the generator running shaft, described generator is connected the wind turning axle with described by floating bearing, described generator running shaft is described relatively, and biasing is provided with to the wind turning axle, the center line of described generator running shaft, be Offset X to the common vertical line length between the center line of wind turning axle, described Offset X is 5～30mm.
For realizing the utility model better, the power of described generator is 200W～20KW.
Working principle of the present utility model is: when wind wheel at a time is in the upwind position, biasing is provided with because the generator running shaft is relatively to the wind turning axle, wind constitutes a flywheel moment to the resistance and the Offset X of wind wheel blade, make wind wheel go to down the wind direction position, it is passive to wind to realize, guarantees that generator moves position on the leeward all the time.The size of Offset X can be by to the aerodynamic force resistance of wind wheel blade, determine the calculating of wind turning axle friction torque and the watt level of generator.
The utility model has following advantage and effect with respect to prior art:
(1) adopt the generator running shaft structure that biasing is provided with to the wind turning axle relatively, make wind-driven generator operate in lee gauge all the time, the power range of suitable generator is big;
(2) this wind-driven generator does not need tail vane, tail wheel equidimension huge, and the member of reliability, poor stability, makes the wind-driven generator overall structure simply compact, and reliable and stable;
(3) owing to do not need members such as tail vane, tail wheel, greatly reduce the equipment input cost.
Description of drawings
Fig. 1 is the structural representation of a kind of passive horizontal axis wind-driven generator to wind of the utility model.
Fig. 2 is that A shown in Figure 1 is to structural representation.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but of the present utility model
Mode of execution is not limited thereto.
Embodiment
As shown in Figure 1, this passive horizontal axis wind-driven generator to wind, comprise wind wheel 1, generator 2, to wind turning axle 3, wind wheel 1 is fixedly mounted on the front end of the running shaft 4 of generator 2, generator 2 passes through floating bearing 5 and wind turning axle 3 is connected, and biasing is provided with the running shaft 4 of generator 2 to wind turning axle 3 relatively, as shown in Figure 2, the center line of the running shaft 4 of generator 2, is Offset X to the common vertical line length between the center line of wind turning axle 3.The power of generator is 200W～20KW, and Offset X is 5～30mm, and the size of Offset X can be by determining the aerodynamic force resistance of wind wheel blade, the calculating of wind turning axle friction torque and the watt level of generator.
The working procedure of this passive horizontal axis wind-driven generator to wind is:
As shown in Figure 1, 2, when wind wheel 1 at a time is in the upwind position, wind constitutes a flywheel moment to the resistance and the Offset X of wind wheel blade 6, makes wind wheel 1 go to down the wind direction position, and it is passive to wind to realize, guarantees that generator 2 operates in lee gauge all the time.
As mentioned above, just can realize the utility model preferably.
Claims (1)
