Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and in particular to a wear-reducing structure, a wind turbine tower platform, and a tower. Background Technology

[0002] A wind turbine is a device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately generates electrical energy.

[0003] As a crucial component of wind turbines, wind turbine towers have evolved significantly, ranging in height from tens to hundreds of meters, leading to an increasing number of large-diameter towers. Due to their considerable height, maintenance of these towers typically involves using a climbing device (or similar tool) to lift and lower personnel. In existing technology, the lifting cable of this device is positioned along the height of the tower. However, under wind conditions or when force is applied to the cable by hand, it sways. This swaying causes the cable to come into contact with objects inside the tower, resulting in wear and tear on both the cable and the contacting objects. Therefore, current technology typically employs a friction-reducing structure (or device) to isolate the lifting cable from these contact points.

[0004] However, since the existing anti-friction structure only has one anti-friction surface, when the anti-friction surface is worn and needs to be removed for replacement, the structural limitations of the existing anti-friction structure make it time-consuming and laborious to remove, thus affecting the replacement efficiency of the anti-friction structure. Summary of the Invention

[0005] This invention provides a wear-reducing structure, a wind turbine tower platform, and a tower, to improve the replacement efficiency of the wear-reducing structure.

[0006] The present invention provides a friction-reducing structure for use in wind turbine tower platforms. The friction-reducing structure includes: a support component having a first end and a second end disposed opposite to each other, and the support component having an installation through hole; a first friction-reducing component disposed at the first end of the support component and having a first friction-reducing surface; and a second friction-reducing component disposed at the second end of the support component and having a second friction-reducing surface.

[0007] In an embodiment of the present invention, the first end of the support member is provided with a first friction-reducing component mounting groove, and the first friction-reducing component is rotatably disposed in the first friction-reducing component mounting groove. The second end of the support member is provided with a second friction-reducing component mounting groove, and the second friction-reducing component is rotatably disposed in the second friction-reducing component mounting groove.

[0008] In an embodiment of the present invention, the first anti-friction surface and the second anti-friction surface are smooth arc surfaces.

[0009] In embodiments of the present invention, both the first and second anti-friction components are anti-friction wheels, and the first and second anti-friction surfaces are the wheel surfaces of the anti-friction wheels.

[0011] In an embodiment of the present invention, the platform cover has a third end and a fourth end disposed opposite to each other. The third end of the platform cover is away from the edge of the platform body, and the fourth end of the platform cover faces the edge of the platform body. The third end of the platform cover is provided with a receiving groove, which extends from the third end of the platform cover to the fourth end of the platform cover.

When the first wear-reducing surface is worn and needs to be removed and replaced, it is not necessary to remove the entire wear-reducing structure.

[0026] Figures 1 to 5 The figures illustrate a friction-reducing structure 1, a wind turbine tower platform 2, and a tower 100 provided in an embodiment of the present invention. As can be seen from the figures, the friction-reducing structure 1 provided in at least one embodiment of the present invention is applied to the wind turbine tower platform 2 and disposed on the platform cover plate 22 of the wind turbine tower platform 2. The friction-reducing structure 1 includes a support component 11, a first friction-reducing component 12, and a second friction-reducing component 13. The first friction-reducing component 12 is disposed on the support component 11 and has a first friction-reducing surface; the second friction-reducing component 13 is disposed on the support component 11 and has a second friction-reducing surface.

[0027] The wear-reducing structure 1 provided in at least one embodiment of the present invention has two wear-reducing surfaces. By providing a first wear-reducing component 12 and a second wear-reducing component 13 on the support component 11, the first wear-reducing component 12 has a first wear-reducing surface and the second wear-reducing component 13 has a second wear-reducing surface. When the first wear-reducing surface is worn and needs to be removed and replaced, it is not necessary to remove the entire wear-reducing structure 1. The positions of the first wear-reducing component 12 and the second wear-reducing component 13 can be interchanged to replace the worn first wear-reducing surface and replace it with a new wear-reducing surface (second wear-reducing surface), thereby improving the replacement efficiency of the wear-reducing structure 1.

[0028] like Figure 3 and Figure 4 As shown, specifically, the support member 11 has a first end 111 and a second end 112 disposed opposite to each other. The first end 111 of the support member 11 is provided with a first friction-reducing component mounting groove 1111, and the first friction-reducing component 12 is rotatably disposed in the first friction-reducing component mounting groove 1111. The second end 112 of the support member 11 is provided with a second friction-reducing component mounting groove 1121, and the second friction-reducing component 13 is rotatably disposed in the second friction-reducing component mounting groove 1121.

[0029] In specific implementation, the first friction-reducing component 12 can roll in the first friction-reducing component mounting groove 1111, which can reduce the friction between the ropes inside the wind turbine tower 3 and the first friction-reducing surface, and reduce the damage caused to the first friction-reducing surface by the ropes (e.g., lifting wire ropes) inside the wind turbine tower 3. The second friction-reducing component 13 can roll in the second friction-reducing component mounting groove 1121, which can reduce the friction between the ropes inside the wind turbine tower 3 and the second friction-reducing surface, and reduce the damage caused to the second friction-reducing surface by the ropes (e.g., lifting wire ropes) inside the wind turbine tower 3, extend the service life of the friction-reducing structure 1, and reduce the number of maintenance times.

[0030] like Figure 4 As shown, the support component 11 may be provided with a mounting through hole 14. For example, the mounting through hole 14 is provided at the upper end of the support component 11. The above-mentioned structural arrangement can facilitate the installation of the support component 11 to the platform cover plate 22 and improve the installation efficiency.

[0031] In some embodiments, a pivot (e.g., connector 232) can be provided on the platform cover plate 22. The pivot can extend into the mounting through hole 14, so that the support member 11 is rotatably disposed on the platform cover plate 22. In specific implementation, when the first anti-friction surface is worn and needs to be removed for replacement, it is not necessary to remove the entire anti-friction structure 1. Simply rotate the support member 11, for example, rotate the support member 11 180 degrees in the horizontal direction, so that the positions of the first anti-friction member 12 and the second anti-friction member 13 are interchanged, and the worn first anti-friction surface can be replaced. Then, a new anti-friction surface (second anti-friction surface) can be installed, and the support member 11 and the platform cover plate 22 can be fixed by snap-fit ​​or adhesive, thereby improving the replacement efficiency of the anti-friction structure 1.

[0032] In some embodiments, the mounting through hole 14 can be a screw hole. The wear-reducing structure 1 can be installed on the platform cover plate 22 by a fastener (e.g., connector 232) extending into the screw hole. Specifically, the fastener can be a screw. When the first wear-reducing surface is worn and needs to be removed for replacement, it is not necessary to remove the entire wear-reducing structure 1. Only the fastener needs to be removed and the position of the support member 11 needs to be adjusted. For example, the support member 11 can be rotated to adjust its position, such as rotating the support member 11 180 degrees in the horizontal direction, so that the positions of the first wear-reducing component 12 and the second wear-reducing component 13 can be interchanged to replace the worn first wear-reducing surface. Then, a new wear-reducing surface (second wear-reducing surface) can be installed and the screws tightened to improve the replacement efficiency of the wear-reducing structure 1.

[0033] In one embodiment of the present invention, the first friction-reducing surface and the second friction-reducing surface are smooth arc surfaces. With the above-mentioned structural arrangement, the friction between the ropes (e.g., lifting wire ropes) inside the wind turbine tower 3 and the first friction-reducing surface and the second friction-reducing surface can be further reduced, thereby reducing the damage caused by the ropes inside the wind turbine tower 3 to the first friction-reducing surface and the second friction-reducing surface.

[0034] Specifically, both the first anti-friction component 12 and the second anti-friction component 13 are anti-friction wheels, and the first anti-friction surface and the second anti-friction surface are the wheel surfaces of the anti-friction wheels.

[0035] like Figure 2 As shown, at least one embodiment of the present invention also provides a wind turbine tower platform 2, including a platform body 21, a platform cover plate 22, and a friction-reducing structure as described above. The platform cover plate 22 is disposed on the platform body 21. The friction-reducing structure includes a support member 11, a first friction-reducing member 12, and a second friction-reducing member 13. The support member 11 is rotatably disposed on the platform cover plate 22. The first friction-reducing member 12 is disposed at the first end 111 of the support member 11 and has a first friction-reducing surface. The second friction-reducing member 13 is disposed at the second end 112 of the support member 11 and has a second friction-reducing surface.

[0036] The specific structure, working principle, and beneficial effects of the wear-reducing structure 1 are the same as those in the above embodiments, and will not be repeated here.

[0037] In specific implementation, through the above structural settings, since the wear-reducing structure 1 is set on the platform cover plate 22, the wear of the lifting wire rope inside the wind turbine tower 3 and the objects in contact with the lifting wire rope can be reduced. That is, not only can the wear of the lifting wire rope be reduced, but the wear of the platform cover plate 22 can also be reduced.

[0038] like Figure 4 As shown, specifically, the platform cover plate 22 has a third end 221 and a fourth end 222 that are arranged opposite to each other. The third end 221 of the platform cover plate 22 is away from the edge of the platform body 21, and the fourth end 222 of the platform cover plate 22 faces the edge of the platform body 21. The third end 221 of the platform cover plate 22 is provided with a receiving groove 2222. The receiving groove 2222 extends from the third end 221 of the platform cover plate 22 to the fourth end 222 of the platform cover plate 22. The support member 11 is slidably disposed in the receiving groove 2222.

[0039] In practice, the distance between the friction-reducing surface (e.g., the first friction-reducing surface) and the rope can be adjusted by controlling the sliding distance of the friction-reducing structure 1 in the receiving groove 2222, so as to facilitate the adjustment of the amplitude of the lifting wire rope swaying.

[0040] like Figure 3 and Figure 4As shown, more specifically, the wind turbine tower platform 2 may also include a connecting component 23, and the supporting component 11 is mounted on the platform cover plate 22 via the connecting component 23.

[0041] In specific implementation, the connecting component 23 can be used to connect the platform cover plate 22 and the wear-reducing structure 1. After the distance of the wear-reducing structure 1 in the receiving groove 2222 is determined, the distance of the wear-reducing structure 1 in the receiving groove 2222 can be fixed by the connecting component 23. That is, the connecting component 23 can play the role of locking the platform cover plate 22 and the wear-reducing structure 1.

[0042] like Figure 4 As shown, specifically, the connecting component 23 may include a detachably connected connecting mating part 231 and a connecting part 232. The connecting mating part 231 includes a plurality of first connecting recesses 2311 and second connecting recesses 2312. The plurality of first connecting recesses 2311 are spaced apart on the upper side of the platform cover plate 22 along the extension direction Y of the receiving groove 2222. The second connecting recesses 2312 are disposed on the support component 11 and their positions correspond to the positions of the plurality of first connecting recesses 2311. The connecting part 232 extends along the thickness direction T of the platform body 21 and passes through the first connecting recesses 2311 and the second connecting recesses 2312. The support component 11 is rotatably disposed on the platform cover plate 22 with the connecting part 232 as the pivot.

[0043] In specific implementation, the connecting piece 232 can be inserted into the corresponding first connecting recess 2311 according to the position of the friction reduction structure 1 in the receiving groove 2222, so as to realize the connection between the platform cover plate 22 and the friction reduction structure 1 (supporting component 11).

[0044] In some embodiments, the support member 11 may be provided with a plurality of second connecting recesses 2312, and the positions of the plurality of first connecting recesses 2311 and the positions of the plurality of second connecting recesses 2312 may correspond one-to-one.

[0045] like Figure 4 As shown, specifically, the mounting through hole 14 can be a screw hole. The wear-reducing structure 1 can be installed on the platform cover plate 22 of the wind turbine tower platform 2 by a fastener (e.g., connector 232) extending into the screw hole. In specific implementation, the fastener can be a screw. When the first wear-reducing surface is worn and needs to be removed for replacement, it is not necessary to remove the entire wear-reducing structure 1. Only the fastener needs to be removed so that the wear-reducing structure 1 can rotate in the receiving groove 2222. Then, the support member 11 is rotated so that the support member 11 drives the first wear-reducing component 12 and the second wear-reducing component 13 to move. For example, the support member 11 can be rotated 180 degrees in the horizontal direction so that the positions of the first wear-reducing component 12 and the second wear-reducing component 13 are interchanged. The worn first wear-reducing surface can be replaced, and then a new wear-reducing surface (second wear-reducing surface) can be installed and the screw tightened. This improves the replacement efficiency of the wear-reducing structure 1.

[0046] Figures 1 to 5 As shown, at least one embodiment of the present invention also provides a tower 100, including the wind power tower platform of the above embodiment.

[0047] The specific structure, working principle, and beneficial effects of the wear-reducing structure 1 are the same as those in the above embodiments, and will not be repeated here.

[0048] In some embodiments, the tower 100 may also include a flange, a horizontally arranged lifting wire rope of the wind turbine tower 3, and a climbing device surrounding the tower 100. Through the above-mentioned structural arrangement, the lifting wire rope can be moved further away from the inner peripheral wall of the flange, thereby reducing the wear on the inner peripheral wall of the flange. In specific implementation, if the wear-reducing structure 1 is not provided on the platform cover plate 22, the lifting wire rope will sway under the action of wind or when people apply force to the lifting wire rope by hand. As a result, the lifting wire rope will come into contact with the inner peripheral wall of the flange during the swaying process, causing the anti-rust paint on the inner peripheral wall of the flange to be worn away, which makes the inner peripheral wall of the flange prone to rusting and affects the service life of the flange.

[0049] like Figure 5 As shown, in some embodiments, the tower 100 may also include a ladder 44 extending along the height direction of the wind turbine tower 3, the ladder 44 being equipped with a climbing device, and a lifting wire rope being installed on the climbing device for the climbing device to be raised and lowered.

[0050] In some embodiments, the side of the ladder 44 facing the lifting wire rope may be provided with the wear-reducing structure 1 described above. This reduces the wear of the lifting wire rope inside the wind turbine tower 3 and the objects in contact with it. In other words, it reduces not only the wear of the lifting wire rope but also the wear of the ladder 44.

[0051] In some embodiments, the ladder 44 has a receiving groove 2222 on the side facing the lifting wire rope. The friction reduction structure 1 can be rotatably disposed in the receiving groove 2222 through its support member 11. Thus, the support member 11 can drive the first friction reduction member 12 and the second friction reduction member 13 to move, thereby realizing the interchange of their positions.

[0052] In this embodiment, the support member 11 has a fifth end and a sixth end that are arranged opposite to each other. The fifth end of the support member 11 faces the lifting wire rope, and the sixth end of the support member 11 faces away from the lifting wire rope. The first anti-friction member 12 is disposed at the fifth end of the support member 11, and the second anti-friction member 13 is disposed at the sixth end of the support member 11. The support member 11 is rotatably disposed in the receiving groove 2222. The rotation axis direction of the support member 11 is the same as the extension direction of the ladder 44. In specific implementation, when the first anti-friction surface is worn and needs to be removed for replacement, it is not necessary to remove the entire anti-friction structure 1. Simply rotate the support member 11, for example, rotate the support member 11 180 degrees in the horizontal direction, so that the positions of the first anti-friction member 12 and the second anti-friction member 13 are interchanged to replace the worn first anti-friction surface and replace it with a new anti-friction surface (second anti-friction surface), thereby improving the replacement efficiency of the anti-friction structure 1.

[0053] That is, the friction reduction structure 1 has two states, namely the first state and the second state. In the first state, the first friction reduction component 12 faces the lifting wire rope, and the second friction reduction component 13 faces away from the lifting wire rope. In the second state, the first friction reduction component 12 faces away from the lifting wire rope, and the second friction reduction component 13 faces the lifting wire rope. The friction reduction structure 1 can drive the first friction reduction component 12 and the second friction reduction component 13 to switch between the first state and the second state.

[0054] It is understood that, in some embodiments, the object to which the wear-reducing structure 1 reduces wear may be the drive wire rope, the safety wire rope, and the adjacent objects thereto.
