Description
Technical Field
The invention relates to a powder sweeping and collecting device, in particular to a powder sweeping and collecting device used in a yaw braking system of a fan.
Background
When the wind generating set is operated on site, the head of the fan continuously adjusts the direction of the head to the wind according to the feedback of the wind vane so as to effectively absorb wind energy, and a yaw system is generally adopted to adjust the head of the fan and enable the head of the fan to be aligned with the wind direction. In order to control the yaw direction of the machine head, yaw control is implemented in a yaw system by using a plurality of pairs of yaw brakes. The brake includes at least a brake disc and a brake disc, and the brake disc is horizontally arranged due to the structure of the fan, so that the brake disc continuously generates brake abrasive dust powder and accumulates on the upper part of the brake disc during the braking process of the brake. If not cleaned in time, the abrasive dust powder can be continuously deposited, rolled and hardened on the yaw brake disc. Therefore, the abrasion to the yaw brake disc is aggravated, and the service life of the yaw brake disc is influenced.
In order to avoid the problems, the currently adopted methods comprise adding a gasket, replacing a brake, replacing a part of brake pads, polishing the brake pads, polishing a brake disc, opening a powder accumulation groove for the brake disc and the like, but the methods are measures taken after the problems caused by powder appear, only can be the subsequent repairing work, and cannot fundamentally solve the problems caused by the powder.
Disclosure of Invention
In order to solve the technical problems of fan noise, fan operation stability and influence on the service life of a brake disc caused by difficulty in timely cleaning of powder in the background art, the invention provides a powder cleaning and collecting device for a fan yaw brake system, which can effectively solve the technical problems.
The utility model provides a fan driftage braking system powder cleans collection device, includes driftage ring gear, brake disc, braking piece, still includes:
the brushing frame is fixedly connected to the yaw gear ring;
the painting is fixedly connected to the painting frame and is in contact with the upper surface of the brake disc; the painting can brush off powder on the brake disc; the contour line of the painting is not parallel to the diameter direction of the brake disc.
Preferably, the angle between the painting contour line and the diameter direction of the brake disc is 30-60 degrees.
Preferably, the angle between the painting contour line and the diameter direction of the brake disc is 30, 40, 45, 50 and 60 degrees.
Preferably, a powder box is further arranged below the brush holder, and the powder box is a box with a single-side opening and can contain powder; the opening of the compact faces upward.
Preferably, the powder box is fixedly connected with the painting frame through a powder box fixing rod.
Preferably, the brushing frame is fixedly connected with the yaw gear ring through a brushing frame fixing rod.
The invention has simple structure, is convenient and practical, and can well solve the technical problems pointed out in the background technology with lower cost.
Drawings
Fig. 1 is a first structural schematic diagram of the present invention.
Fig. 2 is a second structural schematic diagram of the present invention.
Fig. 3 is a partially enlarged schematic view of the present invention.
In the figure: 1-brake disc, 2-brake disc, 3-powder box, 4-powder box fixing rod, 5-painting frame, 6-painting, 7-painting frame fixing rod, 8-yaw motor, 9-yaw gear and 10-yaw gear ring.
Detailed Description
In order to more clearly illustrate the present invention, embodiments of the present invention are further described below with reference to the accompanying drawings.
As shown in FIGS. 1-3, the powder sweeping and collecting device for the yaw braking system of the fan comprises a yaw gear ring, a brake disc and a brake disc, wherein a yaw gear and a yaw motor are further arranged on the yaw gear ring, and the yaw gear ring rotates under the action of the yaw motor and the yaw gear to adapt to the external wind direction so that a machine head is aligned with the wind direction. And a brake pad pushing part (not shown in the figure) is arranged outside the brake pad, and is fixedly connected with the yaw gear ring. On the basis, a painting frame, a painting and a powder box are arranged.
And the brushing frame is fixedly connected with the yawing gear ring through a brushing frame fixing rod. Thus, the brush holder rotates with the yaw ring gear, and the brake pad remains stationary.
The painting is fixedly connected to the painting frame and is in contact with the upper surface of the brake disc; the painting can brush off powder on the brake disc; the contour line of the painting is not parallel to the diameter direction of the brake disc. Thus, when the brush rotates, the powder accumulated on the brake disk can be pushed out of the brake disk, and the powder can be prevented from accumulating on the brake disk. In order to achieve better effect, the angle between the painting contour line and the diameter direction of the brake disc is 30-60 degrees, and 30, 40, 45, 50 and 60 degrees can be selected.
The powder box is a box with a single-side opening and can contain powder; the opening of the compact faces upward.
Preferably, the powder box is fixedly connected with the painting frame through a powder box fixing rod.
When the yawing gear ring is not moved, the braking system keeps a braking state, when the wind direction changes, the yawing gear ring rotates under the action of the yawing motor and the yawing gear, the braking system is released, and when the yawing gear ring is about to move to a preset position, the braking system works, and the braking piece presses the braking disc tightly to enable the yawing gear ring to stop slowly. During this process, the brake pads and the brake disc wear and produce powder, which accumulates on the top of the brake disc. When the yawing gear ring rotates again, the brushing frame, the brushing and the powder box also rotate together with the yawing gear ring, and the brake disc does not move, so that the powder accumulated above the brake disc can be brushed down and stored in the powder box.
