Abstract
The utility model discloses a display shelf of a wind power variable pitch system. An outer ring of a blade bearing is supported and fixed at the front side of a support; a motor and a reduction box are fixed on a cross brace of the support; a driving gear fixed on an output shaft of the reduction box is meshed with the gear ring of an inner ring of the blade bearing; a limit switch and a blade encoder are respectively fixed at two sides of the reduction box; a driving gear of the blade encoder is meshed with the gear ring of the inner ring of the blade bearing; a power management module and a variable pitch controller module are arranged in a control box; and the limit switch and the output end of the blade encoder are connected with the corresponding input end of the variable pitch controller module. In the display shelf, operating components related to the variable pitch system are all integrated on the support, and thus, the configuration of the variable pitch system is displayed intuitively. Working mechanisms such as variable pitch, feather pitch and the like can be simulated under the control of the control box. The display shelf can be used for teaching or exhibition and has the remarkable advantages of simple structure and convenience in operation.
Description
Technical field
The utility model belongs to exhibiting device, particularly relates to a kind of showing stand of wind power pitch-controlled system.
Background technology
The wind-power generating variable oar system is installed in the wheel hub of wind-driven generator as the important structure that the control wind power generator oar blade rotates, because wheel hub self is very heavy and bulky, so except the composing room or wind-powered electricity generation scene of complete system plant, people seldom can see and understand the configuration and the working mechanism of a whole set of pitch-controlled system.
Summary of the invention
The utility model is to watch and understand the configuration of a whole set of pitch-controlled system and working mechanism and propose a kind of showing stand of wind power pitch-controlled system for the ease of people.
The utility model is taked following technical scheme for achieving the above object: this showing stand comprises the blade bearing, motor and reduction box thereof, driven wheel, limit switch, blade encoder and travelling gear thereof, power management module and change oar controller module, feature is, the outer shroud of blade bearing supports and is fixed in the front side of a support, the stull of this support is fixed with motor and reduction box thereof, the driven wheel that is fixed in reduction gearbox output shaft is meshed with blade bearing inner circular tooth circle, the both sides of reduction box casing are fixed with limit switch and blade encoder respectively, the travelling gear of described blade encoder is meshed with blade bearing inner circular tooth circle, described power management module and change oar controller module are arranged at control cabinet, and limit switch is connected with change oar controller module respective input by cable with blade encoder output.
The utility model can also be taked following technical measures:
The power input of described control cabinet power management module is connected in outside 380V AC power supplies.
The utility model beneficial effect and advantage are: this showing stand is all integrated rack-mount with the work components and parts that pitch-controlled system relates to, thereby has showed the configuration of pitch-controlled system intuitively.Under control cabinet control, can simulate working mechanisms such as becoming oar, feathering.This showing stand can be used for teaching or exhibition, has simple in structure, easy to operate outstanding advantage.
Description of drawings
Accompanying drawing 1 is this exhibiting device example structure schematic diagram.
Mark among the figure: 1 support, 1-1 stull, 2 blade bearings, 2-1 inner circular tooth circle, 3 blade encoders, 4 travelling gears, 5 driven wheels, 6 holder parts, 7 limit switches, 8 reduction boxes, 9 motors.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
As shown in the figure, this exhibiting device comprises blade bearing 2, motor 9 and reduction box 8 thereof, driven wheel 5, limit switch 7 and blade encoder 3 and travelling gear 4 thereof.
The outer shroud of blade bearing 2 supports and is fixed in the front side of support 1 by holder part 6, the reduction box 8 of the stull 1-1 fixed electrical machinery 9 of this support, motor 9 is connected by the power shaft of its main shaft with reduction box 8, and the driven wheel 5 that is fixed in reduction gearbox output shaft is meshed with blade bearing inner circular tooth circle 2-1.
Reduction box 8 diagram right sides are fixed with limit switch 7, the sensor side of this limit switch is corresponding with the gear teeth of blade bearing inner circular tooth circle 2-1, reduction box 8 diagram left sides are fixed with blade encoder 3, and the travelling gear 4 of blade encoder is meshed with blade bearing inner circular tooth circle 2-1.
The rotation of the control cabinet (not shown) control motor of present embodiment, control cabinet is provided with the power management module identical with wind power pitch-controlled system and becomes the oar controller module.
Outside 380V AC power supplies is transformed to 560V DC as becoming oar controller module power supply through power management module, and becoming the oar controller module provides 0～400V AC voltage to provide power supply into motor 9.Limit switch 7 is connected with change oar controller module respective input by cable with blade encoder 3 outputs.
As shown in the figure, motor 9 rotates the inner circular tooth circle 2-1 of blade bearing 2 by reduction box 8 and driven wheel 5 thereof, the blade bearing inner circular tooth circle 2-1 that rotates makes 3 work of blade encoder by travelling gear 4 and coded message is fed back to the change oar controller module of control cabinet, limit switch 7 output control signals feed back to control cabinet and become the oar controller module when treating that blade bearing inner circular tooth circle turns to set angle, the pitch-controlled system of showing under the programme-control of change oar controller module will be finished everything, and this has just realized the displaying of pitch-controlled system groundwork mechanism.
Claims (2)
1. the showing stand of a wind power pitch-controlled system, comprise the blade bearing, motor and reduction box thereof, driven wheel, limit switch, blade encoder and travelling gear thereof, power management module and change oar controller module, it is characterized in that: the outer shroud of blade bearing supports and is fixed in the front side of a support, the stull of this support is fixed with motor and reduction box thereof, the driven wheel that is fixed in reduction gearbox output shaft is meshed with blade bearing inner circular tooth circle, the both sides of reduction box casing are fixed with limit switch and blade encoder respectively, the travelling gear of described blade encoder is meshed with blade bearing inner circular tooth circle, described power management module and change oar controller module are arranged at control cabinet, and limit switch is connected with change oar controller module respective input by cable with blade encoder output.
