Example (b):
referring to fig. 1, fig. 1 is a schematic view of an overall structure of a wind power plant in the related art. In the above double-fed wind turbine, in order to improve the stress condition of the speed-increasing machine, the main shaft 160 is mounted on the double bearing housing 100 through two bearings. When dual bearing housing 100 is in a forward and aft bearing housing arrangement, access to the nacelle from the tower is typically provided through the gaps formed between main frame 200, forward bearing housing 310, aft bearing housing 320, and main shaft 160.
Referring to fig. 2, fig. 2 is a schematic structural diagram of another wind power plant in the related art. For a fan with a large single machine power, in order to improve the stress conditions of the main frame 200 and the front and rear bearing seats, the front and rear bearing seats 320 are often designed to be an integrated structure, i.e., the front and rear bearing seats 320 share one housing. At this time, there is little or no space between both sides of the integrated bearing housing 100 and the main frame 200, and it is impossible for maintenance personnel to get in and out of the nacelle from there.
For the blower, an entrance window 330 can be respectively designed at the enclosing plates at the two sides of the main frame 200, so that people can conveniently enter and exit. However, while the power of the whole machine is continuously increased, the yaw moment of the fan is synchronously increased, and more yaw speed reducers 170 need to be arranged on the main frame 200 to meet the requirement, and for passive yaw, the number of the speed reducers is more. Since the yaw speed reducers 170 must be arranged on the circumference centering on the center of the tower and there is a maintenance space, when the number of the yaw speed reducers 170 is large, the speed reducers arranged on both sides of the main frame 200 are compact, the distance between the speed reducers cannot be sufficiently pulled apart, both sides of the main frame 200 are blocked by the yaw speed reducers 170, and maintenance personnel cannot enter the nacelle from both sides of the main frame 200.
In view of this, referring to fig. 3 and fig. 4, the present embodiment provides a novel wind power apparatus, which includes a main frame 200 and a novel bearing seat 100; the bearing block 100 is installed at the machine hatch 150 on the upper part of the main frame 200, the middle part of the integrated bearing block 100 is recessed towards the direction close to the axis of the main shaft 160, so that a larger gap is formed between the outer wall of the bearing block 100 and the main frame 200; maintenance personnel can enter and exit the nacelle through the gap.
The main frame 200 is a hollow housing, two strip-shaped mounting plates 210 are arranged at the upper part of the main frame, and the two strip-shaped mounting plates 210 are horizontally arranged; the two strip-shaped panels are spaced apart and extend in the same direction, thereby forming a strip-shaped machine hatch 150. The bottom of the bearing housing 100 is detachably coupled to the mounting plate 210 such that the entire bearing housing 100 is positioned above the machine hatch 150.
The bearing seat 100 provided by this embodiment includes a connecting cylinder 110 and two seat bodies 120, which are integrally formed, and the two seat bodies 120 are respectively connected to two ends of the connecting cylinder 110. The housing 120 is provided with bearings, and the main shaft 160 penetrates the entire bearing housing 100 and is connected to inner rings of the bearings at both ends.
Specifically, the diameter of the middle portion of the connecting cylinder 110 is smaller than the diameters of both ends thereof, so that the middle portion of the connecting cylinder 110 is recessed to form a space for relief. The above design increases the gap between the outer wall of the connecting cylinder 110 and the main support frame so that maintenance personnel can enter and exit the nacelle through the gap.
Further, a through hole 112 is formed on the side wall of the connecting cylinder 110. The through holes 112 increase the gap between the connecting cylinder 110 and the main support frame, and maintenance personnel can lubricate or perform other maintenance work on the bearings in the bearing housing 100 through the through holes 112.
The upper and lower cylindrical walls of the connecting cylinder 110 are also provided with lightening holes 114, which can reduce the weight of the entire bearing housing 100, thereby facilitating the lifting and installation of the bearing housing 100.
The bottom of the base body 120 of the bearing block 100 is further provided with a connecting plate 140, and the connecting plate 140 is provided with a plurality of bolt holes; the housing 120 is bolted to the main frame 200. A reinforcing rib plate 130 is further disposed between the connecting plate 140 and the outer wall of the seat body 120, and a lifting hole is disposed on the reinforcing rib plate 130.
In order to further enlarge the gap between the outer wall of the connecting cylinder 110 and the main bracket, mounting bosses are provided at both ends of the mounting plate 210 of the main bracket, and mounting holes are provided on the mounting bosses. The connection plate 140 of the base body 120 is connected to the mounting hole of the mounting boss by a bolt. In addition, the inner side of the mounting plate 210 is also recessed away from the main shaft 160, which allows for a larger gap between the edge of the mounting plate 210 and the connecting cylinder 110, thereby further facilitating access to the nacelle by maintenance personnel through the gap.
The method for the wind power equipment to enter and exit the machine hatch 150 provided by the embodiment comprises the following steps:
the middle part of the connecting cylinder 110 is sunken to form an abdicating space, and the mounting boss can lift the whole bearing seat 100 to a certain height; which allows a relatively large clearance to be formed between the connector barrel 110 and the edge of the mounting plate 210 of the main frame 200. When the cabin needs to be accessed for maintenance, the cabin can be accessed through the gap.
Compared with the existing integrated bearing seat 100, the bearing seat 100 provided by the embodiment can facilitate maintenance personnel to get in and out of the cabin; the weight of the entire bearing housing 100 is also reduced to some extent.
It should be noted that this embodiment is only one of many embodiments of the present application, and in other implementations, the side portion of the connecting cylinder 110 of the bearing seat 100 may not be provided with the through hole 112, and a larger abdicating space is avoided only by the way of contracting the middle portion of the cylinder wall of the connecting cylinder 110; alternatively, the relief space may be formed only by providing the through hole 112 at the side of the connector barrel 110.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
