Abstract
The utility model discloses an adjustable wind driven generator which comprises a support, a rotating wheel, a fan shaft and a generator. Blades with adjustable wind borne angles are arranged on the rotating wheel, a wind power sensor connected with a general control unit is arranged on the surface of each blade, the blades are driven through an actuator, and the actuator is controlled through the general control unit. The generate control unit further comprises a speed detection device arranged on the fan shaft and a brake mechanism used for limiting the rotating speed of the fan shaft, and the speed detection device and the brake mechanism are respectively connected with the general control unit. The adjustable wind driven generator has the advantages that the wind borne angles of the blades can be adjusted according to wind direction, the wind wheel is made to be driven easily, and compared with a traditional wind driven generator of a same specification, the adjustable wind driven generator can rotate to generate electricity under a smaller wind power level. In addition, when the fan shaft rotates too fast, namely the rotating speed of the wind wheel is too high, braking will be carried out on the fan shaft, therefore, the rotating speed of the wind wheel is maintained within a reasonable range, and the whole wind driven generator is protected effectively.
Description
Technical field
The utility model relates to wind power generation field, is specifically related to a kind of capable of regulating wind power generator.
Background technique
The wind wheel volume of existing wind-driven generator is larger, and blade mostly is fixing, can't convert loading angle according to wind direction, and, in the windy area of settling wind-driven generator, wind-force is often changeable, and this makes more wind energy be wasted.In addition, quality is heavier, when wind-force is less, also is difficult to start.
In addition, when wind-force is excessive, the wind wheel High Rotation Speed, because wind wheel foreign aid linear velocity is excessive, produce larger additional stress, can threaten to whole wind-driven generator.
The model utility content
The purpose of this utility model is to provide a kind of capable of regulating wind power generator, by the variable blade of loading angle is installed on wind wheel, and wind wheel is carried out to stall-adjusted, overcome existing wind-driven generator and can't regulate the deficiency of wind-engaging angle, the easy stall of wind wheel, thereby realized the purpose of this utility model.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of capable of regulating wind power generator, the generator that comprises support, is located at the runner on support, the fan shaft be connected with runner and is connected with fan shaft, wherein:
Runner is provided with wind-engaging angle adjustable blades, and the surface of these blades is provided with wind sensor, and described wind sensor is connected with a Master Control Unit, and blade is driven by an actuator, and this actuator is controlled by this Master Control Unit;
Master Control Unit also comprises that one is placed in speed measurement device and on fan shaft for limiting the arrestment mechanism of fan shaft rotating speed, and this speed measurement device, arrestment mechanism are connected with Master Control Unit respectively.
In a preferred embodiment of the present utility model, generator, speed measurement device, actuator, Master Control Unit and arrestment mechanism all are located in a Blower Housing, and this Blower Housing outside is streamlined.
The beneficial effects of the utility model are:
Can regulate the vane stress angle of wind wheel according to the wind-force direction, make wind wheel more easily driven, with respect to the wind-driven generator of traditional same size, can under less wind-force rank, rotate generating; In addition, too fast at the fan shaft rotating speed, when wind speed round is too fast, thereby will be braked wind speed round will be maintained in the reasonable scope fan shaft, effectively protect whole wind-driven generator.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is a kind of capable of regulating wind power generator described in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, a kind of capable of regulating wind power generator described in the utility model, the generator 40 that comprises support, is located at the runner 20 on support, the fan shaft 30 be connected with runner 20 and is connected with fan shaft 30; Runner 20 is provided with wind-engaging angle adjustable blades 22, and the surface of these blades 22 is provided with the wind sensor be connected with a Master Control Unit, and blade 22 is driven by an actuator 23, and this actuator 23 is controlled by Master Control Unit;
Master Control Unit also comprises that one is placed in speed measurement device 31 and on fan shaft 30 for limiting the arrestment mechanism 32 of fan shaft 30 rotating speeds, and this speed measurement device 31, arrestment mechanism 32 are connected with Master Control Unit respectively.
In the present embodiment, generator 40, speed measurement device 31, actuator 23, Master Control Unit and arrestment mechanism 32 all are located in a Blower Housing 10.
When the utility model is specifically applied, blower fan 10 outside are streamlined, are easier to like this conduction of air-flow.
The utility model can be regulated the vane stress angle of wind wheel according to the wind-force direction, make wind wheel more easily driven, with respect to the wind-driven generator of traditional same size, can under less wind-force rank, rotate generating; In addition, too fast at the fan shaft rotating speed, when wind speed round is too fast, thereby will be braked wind speed round will be maintained in the reasonable scope fan shaft, effectively protect whole wind-driven generator.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
