Abstract
Automatic bits device that removes of brake disc driftage based on wind turbine generator system. The generating set can frequent driftage when moving, and the brake block in this in-process deviation clamp can produce a large amount of scrap iron bits because of wearing and tearing, and these scrap iron bits can be attached to the brake disc surface, will produce abnormal friction phenomenon when driftage once more. The utility model discloses the constitution includes: driftage brake disc (5) and cabin base (6), the cabin base with the driftage brake disc between install two symmetries and the opposite arrangement remove bits ware (4), remove bits ware and include connecting rod (1), two magnet (2) and two brush (3), two magnet be 120 contained angles and fix the bottom of connecting rod, every the bottom of magnet all be fixed with one the brush. The utility model is used for automatic bits that remove of wind turbine generator system driftage brake disc.
Description
Technical Field
The utility model relates to an automatic bits device that removes based on wind turbine generator system driftage brake disc.
Background
At present, a yaw system of a large wind turbine generator is mostly composed of an electromechanical driving mechanism and a hydraulic braking damping system. The electromechanical driving mechanism is used for driving the wind turbine generator to yaw according to signals sent by the wind direction sensor, so that the wind wheel is opposite to the wind direction to capture wind energy to the maximum extent. The hydraulic braking damping system comprises a hydraulic system and a yaw clamp, and when the wind turbine generator is just opposite to the wind direction for generating electricity, the hydraulic system enables the yaw clamp to brake in a full pressure mode, so that the wind turbine generator is stably just opposite to the wind direction for generating electricity.
When the wind direction changes, the unit starts off the course, and hydraulic pressure descends this moment, produces the damping reduction between brake block and brake disc, ensures the stable driftage of wind turbine generator system. Therefore, the generator set can frequently yaw during operation, a brake pad in the yaw clamp can generate a large amount of waste scrap iron due to abrasion in the process, the waste scrap iron can be attached to the surface of the brake disc, an abnormal friction phenomenon can be generated when the generator set yaws again, the surface of the brake disc becomes rough even can be scratched to generate fine dents due to long-term abnormal friction, and the loss of the yaw braking performance can be caused, so that the operation reliability of the wind turbine set is reduced; and secondly, as the brake pad in the yaw clamp belongs to a consumable product and can be periodically replaced, the abnormal friction can also accelerate the loss of the brake pad in the yaw clamp and even lead to the fragmentation of the brake pad under the serious condition. Therefore, the replacement period of the brake pad can be shortened, the maintenance cost of the generator set is increased, and even the braking performance of the yaw clamp can be failed to damage the normal operation of the wind turbine generator set.
Disclosure of Invention
The utility model aims at providing an automatic bits device that removes based on wind turbine generator system driftage brake disc.
The above purpose is realized by the following technical scheme:
the utility model provides an automatic bits device that removes of brake disc driftage based on wind turbine generator system, its constitution includes: driftage brake disc and cabin base, the cabin base with the driftage brake disc between install two symmetries and the opposite bits of removing ware of arranging, the bits of removing ware include connecting rod, two magnet and two brushes, two magnet be 120 contained angles and fix the bottom of connecting rod, every the bottom of magnet all be fixed with one the brush.
Has the advantages that:
1. the utility model discloses when wind generating set yawing motion, remove the bits device and can produce relative motion with the brake disc of driftage, make and remove the bits ware and can collect the iron fillings on brake disc surface of driftage together then by the magnet absorption of top, both guaranteed the cleanness on brake disc surface of driftage, play the guard action well to the brake disc of driftage, can reduce the wearing and tearing of brake block again, prolong the change cycle of brake block.
2. The utility model discloses two brushes are 120 contained angles and arrange, make and remove the two-way nature that the bits device can satisfy wind generating set driftage to guarantee to the bits effect that removes of driftage brake disc, what we can be very relaxed when patrolling and examining the fan collects the iron fillings on magnet surface, and the convenience is cleaned the unit.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural diagram of a chip remover;
in the figure: 1. a connecting rod; 2. a magnet; 3. a brush; 4. a chip remover; 5. a yaw brake disc; 6. a nacelle base.
The specific implementation mode is as follows:
example 1:
the utility model provides an automatic bits device that removes of brake disc driftage based on wind turbine generator system, its constitution includes: driftage brake disc 5 and cabin base 6, the cabin base with the driftage brake disc between install two symmetries and the opposite arrangement remove bits ware 4, remove bits ware include connecting rod 1, two magnet 2 and two brushes 3, two magnet be 120 contained angles and fix the bottom of connecting rod, every the bottom of magnet all be fixed with one the brush.
The working principle is as follows: the brake disc is fixed when the wind turbine generator system drifts, and only cabin and braking clamp move, so we utilize this characteristic to fix whole chip remover top on the cabin base, and its bottom is vertical downwards and extend to the top of driftage brake disc, and the brush contacts with the driftage brake disc, and when wind turbine generator system driftage motion, the chip remover can produce relative motion with the driftage brake disc, makes the chip remover can collect the iron fillings on driftage brake disc surface together then by the magnet absorption of top. The surface cleaning of the yaw brake disc is guaranteed, the yaw brake disc is well protected, the abrasion of the brake pad can be reduced, and the replacement period of the brake pad is prolonged. And two brushes are symmetrically arranged and are in a herringbone shape with an included angle of 120 degrees, so that the scrap removing device can meet the dual-direction of yawing of the wind generating set, and the scrap removing effect on a yawing brake disc is ensured. When the fan is patrolled and examined, scrap iron on the surface of the magnet can be easily collected, and the unit is conveniently cleaned.
