Preferably, described rotating mechanism further comprises a turning axle and an electric rotating machine, and described turning axle is connected with described rotation platform, and described electric rotating machine drives described drive shaft turns, thereby further drives described rotation platform to rotate.
Preferably, described electric rotating machine drives described drive shaft turns by a gear train.
Preferably, described test board further comprises an administration of power supply, so that the electric energy of described pitch motor and described load motor to be provided.
Preferably, described administration of power supply is embodied as the bus slip ring mode that powers on.
Preferably, described administration of power supply comprises direct current slip ring and exchanges slip ring, and described direct current slip ring is used to described load motor power supply, and described interchange slip ring is used to described pitch motor power supply.
Preferably, described administration of power supply comprises potential device and rectification feedback device, and described potential device and described rectification feedback device are not arranged on described rotation platform.
Preferably, described administration of power supply comprises the inverter being connected with described load motor, and described inverter is arranged on described rotation platform.
Preferably, described administration of power supply comprises the converter plant being connected with described pitch motor, and described converter plant is arranged on described rotation platform.
Preferably, on described rotation platform, be respectively arranged with three described load motors and three described pitch motors.
From such scheme, can find out, because rotation of the present invention becomes oar test board, pitch motor and load motor are arranged on rotatable rotation platform, and adopt the mode that slip ring powers on to solve motor powerup issue, while having simulated wind speed disturbance, blade aerodynamic load changes the state that affects on motor pitch-controlled system, has reflected the true method of operation of blade pitch device.
Accompanying drawing explanation
To the person of ordinary skill in the art is more clear that above-mentioned and other feature and advantage of the present invention by describing the preferred embodiments of the present invention in detail with reference to accompanying drawing below, in accompanying drawing:
Fig. 1 is the structural representation that becomes oar test platform in prior art;
Fig. 2 is the structural front view that in the specific embodiment of the invention, rotation becomes oar test board;
Fig. 3 is the structure side view that in the specific embodiment of the invention, rotation becomes oar test board.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, the present invention is described in more detail by the following examples.
Because real wind-power blade is to be subject to wind speed disturbance in rotary course, thereby producing blade aerodynamic load changes and then motor pitch-controlled system is exerted an influence, so a core concept of the present invention is to introduce a rotating mechanism in becoming oar test platform, thereby real simulation goes out the actual operating of blade pitch device.
In the change oar test board of the specific embodiment of the invention, as shown in Figure 2, comprise pitch motor 1 and load motor 2 in original test board, in addition, this change oar test board also comprises a rotating mechanism, this rotating mechanism comprises a rotatable rotation platform 3, and pitch motor 1 is all arranged in the one side of this rotation platform 3 with load motor 2.Wherein, being connected with test board of the prior art between pitch motor 1 and load motor 2 is as good as.
As shown in Figure 2, this rotation platform can be circular, and the arrow shown in figure represents the sense of rotation of circular rotating platform 3.On the blower fan of reality, comprise three groups of wind-power blades, therefore 3 pitch motors 1 and 3 load motors 2 also can be set respectively on this rotation platform 3, they are uniformly distributed on rotation platform, as shown in Figure 2.
In order to drive this rotation platform 3 to rotate, the rotating mechanism in embodiment also can comprise turning axle 4 and electric rotating machine 5, as shown in Figure 3.This turning axle 4 is connected with the center of circle part at these rotation platform 3 back sides, and this electric rotating machine 5 drives this driving shaft 4 to rotate by gear train 6, thereby further drives this rotation platform 3 around himself center of circle rotation.In one embodiment, this gear train 6 can be embodied as gear ring.
Owing to being provided with rotating mechanism in test board, the power supply of pitch motor 1 and load motor 2 can not adopt traditional electric wire connected mode.In the specific embodiment of the invention, take the bus slip ring mode that powers on to provide electric energy for pitch motor 1 and load motor 2.As shown in Figure 3, the administration of power supply in embodiment comprises direct current slip ring 8 and exchanges slip ring 7, and this direct current slip ring 8 is used to load motor 2 power supplies on rotation platform 3, and this interchanges slip ring 7 is used to the pitch motor 1 on rotation platform 3 to power.
The same with test board of the prior art, in order to guarantee the power supply of pitch motor and load motor, administration of power supply also comprises the device (not shown)s such as potential device, rectification feedback device, inverter and converter plant.In the specific embodiment of the invention, due to the restriction of space and appointed condition, only inverter and converter plant are arranged on rotation platform, wherein inverter is connected with load motor 2, and converter plant is connected with pitch motor 1.Meanwhile, weight, potential device and rectification feedback device that volume is larger are not arranged on rotation platform 3, have reduced like this weight of loading on rotating mechanism, and have taken full advantage of the finite space of rotation platform.
From above-mentioned embodiment, because rotation of the present invention becomes oar test board, pitch motor and load motor are arranged on rotatable rotation platform, and adopt the mode that slip ring powers on to solve motor powerup issue, while having simulated wind speed disturbance, blade aerodynamic load changes the state that affects on motor pitch-controlled system, has reflected the true method of operation of blade pitch device.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
