Abstract
The utility model relates to a yaw backlash adjustment device for a wind turbine generator system, which is characterized in that the backlash adjustment device comprises a frequency converter, wherein the frequency converter is connected with a motor, an overload protection switch and a remote control manual operation keyboard respectively through cables; the overload protection switch is connected with a plug through a line; and a start/stop button, a positive rotation button and a negative rotation button are arranged on the remote control manual operation keyboard. In the utility model, the motor with the frequency converter can rapidly adjust the engaging backlash between a yaw driver and a yaw bearing as required and can perform inching and positive and negative rotation control; the installation precision is greatly increased; and the adjustment efficiency of the backlash is remarkably increased in the assembly process of a fan. With the adoption of the remote control manual operation keyboard for control, the control is quicker and more convenient and visual.
Description
Technical field
The utility model relates to a kind of backlash controlling device that is used for wind-powered electricity generation set yaw system, guarantees the normal operation of wind-powered electricity generation unit.
Background technique
For capturing wind energy to greatest extent, wind power generating set generally is the variation according to wind direction, adopts yaw system to adjust the direction in cabin, is in state down with the wind all the time to guarantee blower fan, also promptly to wind.The yaw system of present most of blower fan generally is by yaw motor, and driftage drives and the driftage bearing is formed, and driftage drives with the driftage bearing is in the same place through gear engagement.During to wind, under the control of control system, yaw motor drives the driftage rotary driving, and then drives yaw axis and forward movingly, accomplishes the wind process thereby the cabin is rotated.
For make yaw system can under the control of control system, drive the cabin steadily, accurately, reliably to wind, driftage is driven and the driftage bearing meshes together well.Backlash is to weigh the necessary parameter of the slick and sly running of gear engagement.So in the installation process of blower fan, just inevitably the driftage actuation gear and the engagement backlash of driftage bearing are regulated.And because the driftage bearing size is very big, conventional method is: rotation driftage earlier drives, and drives the rotation of driftage bearing realizing the adjustment to the two axis relative position, thereby the backlash that makes them is within the scope of technological requirement.
Generally be to insert driftage with dummy shaft to drive center hole at present, drive the driftage rotary driving with the mode of manual work, with the adjustment backlash.This process generally needs several hrs even longer time, and precision is wayward, and working strength is bigger, very influences working efficiency.
Summary of the invention
The utility model technical problem to be solved is the deficiency of, labour consuming time to existing backlash regulative mode, inefficiency, and a kind of backlash controlling device that is used for wind-powered electricity generation set yaw system simple and reasonable, convenient to use is provided.
The utility model technical problem to be solved is to realize through following technological scheme.The utility model is a kind of wind generating set yaw backlash controlling device; Be characterized in; It comprises frequency variator; Described frequency variator is scalped with the remote control hand with motor, overcurrent protection switch through cable respectively and is connected, and overcurrent protection switch is connected with plug through circuit, on the remote control hand is scalped, is provided with start and stop, rotates and reverse button.
The utility model wind generating set yaw backlash controlling device can be set the parameter of frequency variator according to field requirement, regulates variable-frequency motor rotating speed and rotation mode through frequency variator; Said frequency variator is opened with plug through overload protection and is connected to power supply, gives inverter supply.Described motor inserts driftage through motor shaft and drives center hole, drives to drive driftage; Described remote control hand is scalped and is used to control frequency variator, with just commentaries on classics, counter-rotating, crawl and the start and stop etc. of control motor.
Compared with prior art; The beneficial effect of the utility model is; The motor of band frequency variator quick adjustment driftage as requested drives and driftage bearing engaging tooth crack; Have crawl and clockwise and anticlockwise control simultaneously, improved the precision of installing greatly, also improved the efficient that backlash is regulated in the blower fan assembly process simultaneously significantly.Employing remote control hand is scalped to control and is made control more convenient, directly perceived.
Description of drawings
Fig. 1 is the electrical principle schematic representation of the utility model;
Among the figure: 1 is motor, and 2 is frequency variator, and 3 is overcurrent protection switch, and 4 is plug, and 5 scalp for the remote control hand.
Embodiment
Following with reference to accompanying drawing, further describe the concrete technological scheme of the utility model, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.
Embodiment 1; A kind of wind generating set yaw backlash controlling device; It comprises frequency variator 2; Described frequency variator 2 is scalped through cable and motor 1, overcurrent protection switch 3 and remote control hand respectively and 5 is connected, and overcurrent protection switch 5 is connected with plug 4 through circuit, scalps at the remote control hand and is provided with start and stop on 5, rotates and reverse button.
In Fig. 1, motor 1 adopts triangle to connect, and the U1 of motor 1, V1, W1 end are connected with U, V, the W end of frequency variator 2 respectively, through the changing parameter motor speed of frequency variator 2.For the bearing that prevents to go off course fortuitous event such as be stuck causes motor overload to burn, frequency variator 2 power input terminal R, S, T are taken over L1, L2, the L3 terminal that carries protective switch 3 respectively.Overcurrent protection switch 3 connects a 380V plug for industrial use 4.The parameter of frequency variator 2 is set, and making S1 terminal function is three-wire type operation control, and S2 terminal function is for just transporting row, and S1 terminal function is counter-rotating.Q21, Q22, Q23 end that S1, S2, S3 terminal are scalped with the remote control hand respectively are connected, realization Q21, Q22, Q23 switch control respectively motor start and stop, rotate and reverse.
