Description
Technical Field
The utility model belongs to the technical field of wind power generation auxiliary equipment, and particularly relates to a device for improving the running environment of a yaw position proximity switch.
Background
The yaw system is an important component of a wind generating set, and the wind generating set aligns the wind direction through yaw so as to be connected to the grid for power generation. Driftage proximity switch is used for supplementary detection wind generating set driftage position, avoids the driftage angle to exceed the limit value and leads to the cable twist-off, and fan driftage position detection proximity switch is close to the big tooth of driftage, because lubricating oil is more on the big tooth of driftage, leads to proximity switch to be polluted comparatively seriously, if mix with metal such as iron fillings in the grease still can influence measurement accuracy.
Disclosure of Invention
The utility model aims at the problems and provides a device which can keep the measurement precision of a proximity switch and improve the operation environment of the proximity switch at a yaw position in the operation process of a fan.
In order to achieve the above purpose, the utility model adopts the following technical scheme, the utility model comprises a support frame, a proximity switch corresponding to a gear of a wind driven generator is arranged on the support frame, and the utility model is characterized in that: the supporting frame is provided with a hairbrush, and the bristles of the hairbrush are in contact with the gear of the wind driven generator; the proximity switch is arranged behind the brush, and the gear of the wind driven generator firstly passes through the brush and then passes through the proximity switch in the rotating process.
As a preferable scheme of the present invention, the brush is disposed on an L-shaped fixing seat, and the fixing seat is fixed in the strip-shaped mounting groove of the supporting frame by a transverse fixing bolt.
Further, a vertical long round hole is formed in the fixing seat, and the brush is fixed to the long round hole of the fixing seat through a vertical fixing bolt.
The utility model has the beneficial effects that: 1. by arranging the hairbrush, the hairbrush can effectively prevent lubricating oil from polluting the proximity switch in the running process of the gear of the wind driven generator, and the long-time high-precision running of the proximity switch is ensured.
2. The position of the brush can be conveniently controlled through the long strip-shaped mounting groove and the vertical long round hole, and the brush is convenient to mount and adjust, so that the optimal oil removing effect is ensured.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Fig. 2 is a bottom view of fig. 1.
Fig. 3 is a sectional view a-a of fig. 1.
In the attached drawing, 1 is a transverse fixing bolt, 2 is a fixing seat, 3 is a vertical fixing bolt, 4 is a brush, 5 is a proximity switch, 6 is a support frame, 7 is a gear of a wind driven generator, 8 is an installation groove, and 9 is a vertical long round hole.
Detailed Description
The utility model comprises a support frame 6, a proximity switch 5 corresponding to a gear 7 of a wind driven generator is arranged on the support frame 6, and the utility model is characterized in that: the supporting frame 6 is provided with a brush 4, and bristles of the brush 4 are in contact with a gear 7 of the wind driven generator; the proximity switch 5 is arranged behind the brush 4, and the gear 7 of the wind driven generator firstly passes through the brush 4 and then passes through the proximity switch 5 in the rotating process.
As a preferable scheme of the utility model, the brush 4 is arranged on an L-shaped fixed seat 2, and the fixed seat 2 is fixed in an elongated mounting groove 8 of a support frame 6 through a transverse fixing bolt 1.
Furthermore, a vertical long circular hole 9 is formed in the fixing seat 2, and the brush 4 is fixed to the long circular hole of the fixing seat 2 through a vertical fixing bolt 3.
When the oil lubrication device is used, the brush 4 can prevent lubricating oil from dropping onto the proximity switch 5, and the proximity switch 5 can be ensured to run for a long time with high precision.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the utility model.
