Description

[0001] The present invention relates to the technical field of wind power generation, and in particular to a yaw carbon powder collecting device for a wind generator set. Background Art

[0002] The friction between the yaw brake pad and the yaw brake disc in the wind turbine generates carbon powder. Manual cleaning without special tools cannot achieve the purpose of thorough cleaning, which invisibly increases the labor intensity of the personnel.

[0055] During use, the handle portion 303 is pulled to rotate the connecting portion 302. Due to the limitation of the limiting slider 103b on the limiting slide groove 103c, the connecting portion 302 drives the arc-shaped sealing plate 103d to open, and the arc-shaped sealing plate 103d drives the movable sealing plate 103a to open. The moving device allows the yaw brake pad to enter the interior of the shell plate 102a. At the same time, the yaw brake pad squeezes the inclined surface of the auxiliary plate 104a, allowing the yaw brake pad to enter the auxiliary wheel 104b. The handle portion 303 is loosened to allow the movable sealing plate 103a and the arc-shaped sealing plate 103d to squeeze the surface of the yaw brake pad, thereby sealing the gap between the shell plate 102a and the yaw brake pad, and starting the dual-axis motor 10 6b drives the gear 106c to rotate. Due to the setting of the arc-shaped rack 106d, the gear 106c rotates and drives the dual-axis motor 106b to move along the installation slide 106a.

[0056] Example 3

[0057] 1-7 , a third embodiment of the present invention is shown. This embodiment differs from the second embodiment in that the shaft portion 301 includes a shaft 301 a rotatably disposed on the housing plate 102 a and a coil spring 301 b fixedly disposed on the shaft 301 a .

[0058] Preferably, the shell plate 102a is fixedly installed with a mounting block, the rotating shaft 301a is rotatably set on the mounting block, one end of the coil spring 301b is fixed on the mounting block, and the other end is fixed on the rotating shaft 301a. The elastic force of the coil spring 301b makes the movable sealing plate 103a and the arc-shaped sealing plate 103d closely contact with the surface of the yaw brake pad to prevent carbon powder leakage during cleaning.

[0059] The connecting portion 302 includes a connecting slot plate 302a fixedly disposed on the rotating shaft 301a, a connecting sliding block 302b slidingly disposed in the connecting slot plate 302a, and a connecting rotating block 302c rotatably disposed on the connecting sliding block 302b and connected to the arc-shaped sealing plate 103d.

[0062] The remaining structures are the same as those of Example 2.

[0063] When the cleaning device is needed to clean the uncleaned part during use, there is no need to remove the device and reinstall it. You only need to pull the pulling sleeve 303b to open the movable sealing plate 103a, and then rotate the device. Pull the pulling sleeve 303b to move along the extension rod 303a, and the pulling sleeve 303b pulls the pull rope 303c to rotate the rotating shaft 301a. The rotation of the rotating shaft 301a tightens the coil spring 301b. At the same time, the rotating shaft 301a drives the connecting slide plate 302a to rotate, and the connecting slide plate 302a rotates and drives the connecting sliding block 302b to move along the connecting slide plate 30 2a moves, and at the same time, the connecting sliding block 302b drives the connecting rotating block 302c to move the arc-shaped sealing plate 103d, and the arc-shaped sealing plate 103d drives the movable sealing plate 103a to move, thereby opening the movable sealing plate 103a, and rotating the device along the yaw brake pad. Due to the setting of the auxiliary wheel 104b, the friction between the yaw brake pad and the device is reduced, and the rotation of the device is convenient. After rotating to the uncleaned part, loosen the pulling sleeve 303b, and the coil spring 301b is relaxed to drive the arc-shaped sealing plate 103d and the movable sealing plate 103a to be in close contact with the surface of the yaw brake pad, and continue cleaning.
