Detailed Description
Embodiments of the present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. In the drawings, like numbering represents like elements throughout. The figures may not be drawn to scale and the relative sizes, proportions and depictions of the elements in the figures may be exaggerated for clarity, illustration and convenience. Further, in order to clearly show the relationship between the components, the internal configuration, and the like, in the partial view, the partial members are omitted from illustration, and further, in the partial view, in order to clearly show the internal structure, a part of the external member (for example, a nacelle cover in fig. 1) is illustrated as being transparent.
Referring to fig. 1 to 5, the nacelle cover of the wind turbine generator system includes a nacelle cover door 20, and the nacelle cover driving system according to the present invention drives the nacelle cover door 20 to open or close. According to the utility model discloses a wind generating set's cabin cover actuating system includes drive arrangement 100.
Drive 100 may include a support bracket 110 and a linkage 120. The support bracket 110 may be fixed to the base 10 of the wind turbine. A first end of the link 120 is movably connected to the support frame 110, a second end of the link 120 may be hinged to an inner wall of a first side portion of the nacelle cover door 20 of the nacelle cover, and a second side portion of the nacelle cover door 20 opposite to the first side portion is hinged to the base 10, wherein the first side portion of the nacelle cover door 20 is rotated around the second side portion of the nacelle cover door 20 by moving the first end of the link 120 along the support frame 110 to open or close the nacelle cover door 20.
Specifically, taking fig. 1 to 3 as an example, the supporting frame 110 may include a vertical bracket 111 and a horizontal rail 112, and the vertical bracket 111 is fixed on the base 10 and supports the horizontal rail 112. Horizontal guide rails 112 may be disposed horizontally near the top of nacelle cover door 20. A first end of link 120 may be movably connected to horizontal rail 112. The second end of the link 120 is hinged to the side wall of the nacelle cover door 20 near the top of the nacelle cover door 20. Both ends of the horizontal guide rail 112 are provided with stop blocks 1123 for limiting the movement of the first end of the link 120.
In the nacelle cover driving system according to the present invention, the first end of the connecting rod 120 may be driven to perform a linear motion along the supporting frame 110 by a screw driving, a rack and pinion driving, a worm and gear driving, a hydraulic driving, or a cylinder driving.
As an example, as shown in fig. 4 and 5, the horizontal guide rail 112 of the support bracket 110 may include a threaded rod 1121 and a support 1122, the threaded rod 1121 and the support 1122 may be parallel to each other, and both ends of the threaded rod 1121 and the support 1122 are commonly connected to the stopper 1123, the threaded rod 1121 being rotatable in the stopper 1123. In addition, the supporting member 1122 can be bolted to a supporting structure (e.g., a framework) on the top of the nacelle through the fixing plate 1126 (e.g., an L-shaped support plate), so that the mounting and dismounting are convenient, the reuse of the whole driving device is facilitated, and the cost is reduced.
Stop block 1123 disposed at one end (e.g., left end in fig. 4) of horizontal guide 112 may leave a driving interface to connect one end of coupling 1124 and rotating member 1125 to each other through the driving interface, and the other end of coupling 1124 may be connected to threaded rod 1121 so that coupling 1124 may be rotated when rotating member 1125 is rotated, thereby rotating threaded rod 1121.
The first end of the link 120 may be connected to the support 110 by a moving link 121 and a one-way rotary joint, a two-way rotary joint 122 or a ball-and-socket joint hinged to the moving link 121, and linearly move along the support 110. Specifically, moving loose piece 121 may have an internal thread that mates with an external thread of threaded rod 1121, and moving loose piece 121 may be supported by support 1122, so that moving loose piece 121 may move along threaded rod 1121 by thrust between the internal and external threads and support of support 1122 when threaded rod 1121 is rotated by rotating rotary piece 1125.
During driving, when the movable block 121 with the first end of the link 120 moves from the end of the horizontal rail 112 far from the side wall of the nacelle cover to the end of the horizontal rail 112 near the side wall of the nacelle cover, the second end of the link 120 outwardly supports the first side of the nacelle cover door 20 (for example, the side wall near the top of the nacelle cover) along with the movement of the first end of the link 120, and since the second side of the nacelle cover door 20 is hinged to the base 10, the nacelle cover door 20 can be gradually unfolded outwardly with the second side as a pivot axis (for example, a connecting shaft between the nacelle cover door 20 and the bottom support 200, which will be described below); when the movable block 121 with the first end of the connecting rod 120 moves from the end of the horizontal guide rail 112 close to the side wall of the nacelle cover to the end of the horizontal guide rail 112 far from the side wall of the nacelle cover, the second end of the connecting rod 120 pulls the first side part of the nacelle cover door 20 inwards along with the movement of the first end of the connecting rod 120, and the nacelle cover door 20 is gradually closed inwards by taking the second side part as a pivot shaft, so that the nacelle cover door 20 can be opened and closed. Although the drawings show that the first side portion of the nacelle cover door 20 is a side wall near the top of the nacelle cover and the second side portion is the bottom of the nacelle cover side wall, it is not limited thereto as long as the driving device drives one side of the nacelle cover door with the pivot support point of the nacelle cover door located on the other side opposite to the one side (the driving position is separated from the pivot support point).
in this embodiment, the horizontal guide rail 112 is preferably horizontally disposed near the top of the nacelle cover door 20, and the second end of the link 120 is connected on a first side of the nacelle cover door 20 near the top of the nacelle cover. As such, when the first end of the link 120 slides along the horizontal guide rail 112 to drive the opening or closing of the nacelle cover, the force-bearing point of the nacelle cover door (i.e., the position to which the second end of the link 120 is connected) is close to the entire top of the nacelle cover, and thus, the top driving method as described above can improve the stability of the windward side of the nacelle cover door during the opening of the door, compared to the method of opening or closing the nacelle cover by hydraulically driving the hinge connected to the bottom of the nacelle cover door.
in the above configuration, the rotation piece 1125 may be a long arm ratchet wrench, so that a driving force may be provided by manually rotating the rotation piece 1125. However, the present invention is not limited thereto, and the threaded rod 1121 may be directly connected to a shaft of a stepping motor so as to provide a driving force to the threaded rod 1121. Under the condition of using the motor for driving, the rotating speed can be adjusted, the driving process is quick, stable and efficient, and under the condition of using manual driving, external electric equipment (such as a lead, a power supply and the like) does not need to be installed, and the manual operation can be carried out by an operator, so that the operation of the switch of the cabin cover under the condition that the electric equipment of the cabin is not complete in the installation process of the wind generating set is particularly facilitated. In addition, an electric driving device and a manual driving device can be mounted on the horizontal guide rail 112 at the same time to switch the nacelle cover under different external conditions (power on or power off), and the manual driving device and the electric driving device can be connected with the threaded rod 1121 through the same interface, so that manual and electric switching is facilitated.
Furthermore, in addition to the stop baffles 1123 disposed at the two ends of the horizontal guide rail 112 for limiting the movement of the first end of the connecting rod 120, although not shown in the drawings, a limiting mechanism may be disposed on the horizontal guide rail 112, for example, the limiting mechanism may be connected to the threaded rod 1121, and when the nacelle cover door 20 needs to be stopped at a certain position during the opening or closing process, the rotation of the threaded rod 1121 may be stopped by the limiting mechanism, for example, the threaded rod 1121 is locked, so that the movement of the movable block connected to the first end of the connecting rod 120 is stopped, thereby achieving the effect of stopping the opening or closing of the nacelle cover door 20.
Although the embodiment in which the first end of the link 120 is moved along the support bracket 110 by moving the movable block to drive the nacelle cover switch is described above with reference to fig. 4 and 5, the driving manner is not limited thereto, and for example, screw driving, rack and pinion driving, worm and gear driving, hydraulic driving, cylinder driving, and other linear driving manners may be adopted as long as the first end of the link 120 can be moved along the support bracket 110.
In the above-described process of opening and closing the nacelle cover, when the first end of the link 120 moves along the support frame 110 (e.g., the horizontal guide rail 112), since the second end of the link 120 is fixed to the nacelle cover door 20 which performs a rotational motion, the motion trajectory of the second end of the link 120 is actually a circular motion around the pivot axis of the nacelle cover door 20 (i.e., the horizontal height of the second end changes), and since the first end of the link 120 always moves on the horizontal guide rail 112 which is horizontally disposed (i.e., the horizontal height of the first end does not change), the tilt angle of the link 120 changes during the motion process, that is, the link 120 tilts from the horizontal direction to the vertical direction during the process that the first end of the link 120 moves from a position far from the side wall of the nacelle cover to a position close to the side wall of the nacelle cover; otherwise, the link 120 is inclined from the vertical direction to the horizontal direction.
Therefore, it is required that the link 120 is pivotally movable in at least one direction with respect to the support frame 110 with the first end of the link 120 as a pivot point, and the link 120 is pivotally movable in at least one direction with respect to the inner wall of the nacelle cover door 20 with the second end of the link 120 as a pivot point.
Specifically, a first end of the link 120 is rotatably connected to the moving link 121 moving along the horizontal guide rail 112 and a second end of the link 120 is rotatably connected to an inner wall of the nacelle cover door 20. As an example, as shown in fig. 4 and 5, a first end of the link 120 may be connected to the moving flap 121 by a double swivel joint 122, and a second end of the link 120 may be connected to an inner wall of the nacelle cover door 20 by a double swivel joint 122. Here, for ease of installation, the second end of the link 120 may be connected to the fixed attachment base 123, and thus to the nacelle cover door 20, by the bidirectional rotary joint 122, wherein the fixed attachment base 123 may be connected to an embedded part on the inner wall of the nacelle cover door 20. Here, the embedded part may be a structural member embedded inside the nacelle cover, for example, a connection plate with a mounting screw hole.
Because the bi-directional rotary joint 122 has four degrees of freedom, the link 120 can be adjusted in angle during movement, and adjustment to fit assembly errors can be achieved.
As shown in fig. 4 and 5, the connection between the end of the connecting rod 120 and the bidirectional rotary joint 122 and the connection between the bidirectional rotary joint 122 and the movable loose piece 121 or the fixed connection seat 123 may be made by bolts, but it is not limited thereto, and the connecting rod and the rotary joint may be connected in other pivotable manners.
In addition, the rotatable connection manner of the connecting rod 120 with the movable loose piece 121 and the nacelle cover door 20 is not limited to this, and the first end and the second end of the connecting rod 120 may also be connected to the support frame 110 and the nacelle cover door 20 through a unidirectional rotary joint or a universal ball joint, respectively.
Although it is described above that the first end of the link 120 linearly moves in the horizontal direction along the support bracket 110, the nacelle cover driving system according to the present invention is not limited thereto, and the support bracket 110 may include a vertical guide provided in the vertical direction, to which the first end of the link 120 is connected, and the second end of the link 120 is hinged on the side wall of the nacelle cover door 20 near the top of the nacelle cover door 20, so that the first end of the link 120 may move in the vertical direction along the vertical guide of the support bracket 110. In this case, the link 120 may always maintain an inclination angle greater than a predetermined angle with respect to the vertical guide so that the link 120 may move on the guide by the driving force.
Specifically, when the first end of the connecting rod 120 moves from the lower end of the vertical guide rail (the end close to the base) to the upper end of the vertical guide rail (the end close to the top of the nacelle), the included angle of the connecting rod 120 relative to the vertical guide rail gradually increases, the connecting rod 120 tends to rotate in the horizontal direction, and the second end of the connecting rod 120 outwards supports the opening of the nacelle cover door 20; when the first end of the connecting rod 120 moves from the upper end of the vertical guide rail to the lower end of the vertical guide rail, the included angle of the connecting rod 120 relative to the vertical guide rail becomes smaller, the connecting rod 120 tends to rotate in the vertical direction, and the second end of the connecting rod 120 pulls the cabin cover door 20 inwards, so that the cabin cover door 20 is closed. In this case, the connecting rod 120, the movable block and the nacelle cover may also be connected by the above-described unidirectional rotary joint, bidirectional rotary joint or universal ball joint, and the above-described driving method may also be applied to the driving method of the connecting rod 120, which is not described herein again.
The nacelle cover driving system according to the present invention may further include a bottom support device 200. The bottom support 200 is fixed to the base 10 and the second side of the nacelle cover door 20 is hinged to the bottom support 200. The configuration of the bottom supporting device 200 is described below with reference to fig. 1 to 3 and 6.
The bottom supporter 200 includes a rotation coupling part 210 and a fixing support part 220. The rotation connection part 210 may be pre-embedded in the inner wall of the cabin cover door 20, one end of the fixing and supporting part 220 is fixed on the base 10, and the other end of the fixing and supporting part 220 is hinged with the rotation connection part 210.
As shown in fig. 1 and 6, one end of the fixed support 220 is fixed to the base 10 to support the rotation connection 210 and the nacelle cover door 20 to which the rotation connection 210 is fixed. The rotation connection portion 210 may be connected to the other end of the fixed support portion 220 through a unidirectional rotation joint, so that the nacelle cover door 20 may rotate with respect to the fixed support portion 220 centering on the unidirectional rotation joint when the driving device 100 drives the nacelle cover door 20 to open or close.
Preferably, the fixing support 220 may have a triangular support structure, for example, may be formed as a triangular bracket. The triangular bracket may be fixedly connected with the base 10 by a bolt fastener or the like, for example, an interface (e.g., a bolt hole) for fixing the triangular bracket may be reserved on the whole framework structure inside the base. However, the form of the fixing support 220 is not particularly limited, and for example, a linear single bar bracket, a two linear bar bracket, or the like may be used. Furthermore, in case the bottom support means 200 is not provided, the lower part of the nacelle cover door 20 (e.g. the above mentioned second side part) may be directly hinged to the base.
The utility model also provides a wind generating set, wind generating set include as above cabin cover actuating system.
The nacelle cover driving system described above may be applied to a double-side opened nacelle cover as shown in fig. 1 to 3, and when applied to a double-side opened nacelle cover, the nacelle cover driving system may include two pairs of guide rails and links symmetrically arranged, for example, as shown in fig. 2, the horizontal guide rail 112 may include two-part guide rails to allow the left and right side links 120 to drive the opening and closing of the nacelle cover on both sides, respectively, wherein the horizontal guide rail and the link shown in fig. 4 may correspond to the guide rail and the link on the right half of fig. 3. In this case, the movement stroke of each side nacelle cover is short, so that the driving process is relatively stable. But according to the utility model discloses a cabin cover actuating system also can be applied to the cabin cover that the unilateral was opened, according to specific needs to guide rail and link length, height and set up the position adjust can.
