Description
Technical Field
The application relates to the technical field of wind power generation, in particular to a waste grease automatic collection device for a variable-pitch bearing of a fan.
Background
The wind generating set blade is connected with the hub through the variable pitch bearing, and because the weight of a single blade reaches more than ten tons, the load born by the variable pitch bearing is very high, and lubricating grease is required to be added into the variable pitch bearing for lubrication in order to reduce the abrasion of the blade in the variable pitch process. With the increase of the service time, the grease will fail due to aging, so that new grease needs to be added periodically to discharge old grease. In the early stage, new grease is manually and periodically added to drain old grease, but the operation of each unit is not completely the same, so that the aging time of grease is not completely the same, and part of units are aged before a specified grease changing date, but are not timely replaced, so that abnormal wear or scrapping of bearings is caused, and the maintenance mode of manually and periodically changing grease is defective. With the progress of technology, an online automatic grease adding device is started to appear in recent years, and new grease is injected into a bearing through a grease injection hole every certain time, and old grease is discharged into a waste grease collecting bottle from a grease discharging hole. The automatic grease adding avoids the problem caused by untimely grease replacement, but the grease has high viscosity, old grease is easy to agglomerate and solidify when meeting air at a grease discharging port, so that a part of grease discharging holes can be blocked, old grease cannot be discharged, new grease cannot be added in place, and the phenomenon of uneven lubrication occurs.
The patent with the publication number of CN216345328U discloses an automatic oil sucking and discharging device for a wind generating set bearing, which is complex in structure, mixed air in grease can cause inaccurate pressure sensing collection, and further a system cannot work normally, meanwhile, a plurality of device pipelines and joints are arranged, the device is easy to block and fault, a blade pitch bearing always rotates fast along with a wind turbine hub, and unstable working environment is easier to cause system faults. The patent with the publication number of CN218409500U discloses a bearing grease discharging device, and the patent describes that 'when grease in a bearing needs to be discharged, a grease discharging pipe is inserted into a grease discharging channel of the bearing', and the device can only be used during regular cleaning and cannot collect waste grease on line at any time, so that the waste grease collecting requirement of a pitch-variable bearing is not met. Therefore, the inventor provides an automatic collection device for waste grease of a variable-pitch bearing of a fan

Detailed Description
Example 1
Referring to fig. 1-2, in this embodiment, the automatic collection device for waste grease of a variable pitch bearing of a fan includes a bottle body 10 screwed with a bottle cap 20, a backflow preventing cover 30 is disposed on the inner side of the bottle cap 20, a flow guiding tube 40 for screwing with a grease discharging hole of a bearing seat is arranged on the bottle cap 20 in a penetrating manner, a guiding rod 42 is disposed on a connecting block 41 at the inner end of the flow guiding tube 40, a sliding block 50 is slidably sleeved on the guiding rod 42, a connecting rod 51 on the sliding block 50 extends into the flow guiding tube 40, and a grease scraping ring 52 is disposed at the end of the connecting rod 51.
In this embodiment, the bottle 10 is locked on the bearing seat by screwing the flow guiding tube 40 and the lipid discharging hole, when the bottle 10 rotates along with the bearing seat, the sliding block 50 will reciprocate along the guiding rod 42 due to the action of gravity and drive the connecting rod 51 and the lipid scraping ring 52 to reciprocate synchronously in the flow guiding tube 40, so that the waste lipid flowing into the flow guiding tube 40 via the lipid discharging hole is extracted into the bottle 10, the automatic lipid pumping function is realized, and the device has the advantage of simple operation.
It should be noted that, the flow guiding tube 40 stretches into the inside of the grease discharging hole of the bearing seat and is in threaded connection with the grease discharging hole, the connecting block 41 is located at the inner side of the bottle cap 20, when the flow guiding tube 40 is screwed down in the grease discharging hole, the bottle cap 20 can be pressed on the surface of the bearing seat by extrusion of the connecting block 41, fixation of the bottle cap 20 is achieved, and then the bottle body 10 and the bottle cap 20 are screwed and connected, so that installation fixation of the bottle body 10 can be completed.
It should be noted that, the inner cavity of the flow guiding tube 40 is circulated with the lipid discharging hole, the waste lipid in the lipid discharging hole can flow into the flow guiding tube 40, the bottle body 10 rotates slowly along with the bearing seat in the vertical plane, at this time, the sliding block 50 can be acted by centrifugal force theoretically, however, because the overall rotation speed of the bearing seat is slower, and the weight of the sliding block 50 is larger, the influence of centrifugal force on the sliding block 50 can be ignored, the sliding of the sliding block 50 along the guiding rod 42 is mainly determined by the space position of the sliding block 50, when the bottle body 10 rotates to the lower side along with the bearing seat, the sliding block 50 moves away from the bottle cap 20 along the guiding rod 42 under the action of self gravity, at this time, the connecting rod 51 and the lipid scraping ring 52 are separated from the flow guiding tube 40 and retreated into the bottle body 10, thus completing the lipid pumping action; similarly, when the bottle body 10 rotates to the upper side along with the bearing seat, the sliding block 50 moves along the guiding rod 42 to approach the bottle cap 20 under the action of self gravity, at this time, the connecting rod 51 and the scraping ring 52 move into the guiding tube 40 again, and the guiding tube 40 is closed.
It should be understood that, in this embodiment, when the bottle body 10 rotates along with the bearing seat, the spatial position of the slider 50 will change, so that the slider 50 reciprocates along the guide rod 42 under the action of its own gravity, thereby achieving the purpose of automatically extracting waste grease from the variable-pitch bearing of the fan, and having the advantage of simple operation.
In this embodiment, optionally, the edge 31 of the backflow preventing cap 30 is clamped between the bottle cap 20 and the port of the bottle body 10, so as to fix the backflow preventing cap 30, and make the disassembly and assembly of the backflow preventing cap 30 easier, as an example, the backflow preventing cap 30 is configured to be a cylinder coaxially arranged with the bottle cap 20, and the connection block 41, the guide rod 42, the limit nut 43 and the slider 50 are all arranged inside the backflow preventing cap 30.
In addition, the flow guide tube 40 is coaxially arranged with the bottle cap 20 as a whole, a sealing ring 44 is arranged between the connecting block 41 and the bottle cap 20, the sealing ring 44 can prevent waste grease collected by the bottle body 10 from leaking from the joint of the bottle cap 20 and the flow guide tube 40, the sliding block 50 and the connecting block 41 are formed into a disc shape which is coaxially arranged, two guide rods 42 are uniformly distributed along the circumferential direction of the connecting block 41, the guide rods 42 are in screwing connection with the connecting block 41 for easy dismounting, and meanwhile, a limit nut 43 is screwed at the end part of the guide rods 42.
Optionally, in order to keep the internal pressure of the bottle 10 constant, an air pipe 11 is provided on the bottle 10, the air pipe 11 communicates the inside with the outside of the bottle 10, and as an example, the air pipe 11 is in threaded connection with the bottle 10, so as to facilitate the disassembly and assembly of the air pipe 11.
