Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation, and particularly relates to an anti-sinking cable guiding structure for a wind turbine generator set. Background Technique

[0002] During the operation of a wind turbine generator set, how to manage and maintain the cables has always been an important issue. Especially at the cable hole of the yaw platform, the arrangement and fixation of the cables are particularly important.

[0003] The existing method for cable arrangement and fixation is as follows: at the cable hole of the yaw platform of the wind turbine generator set, a cable guiding ring is installed to straighten the cable path and avoid entanglement.

[0004] However, if the cable guiding ring is fixedly installed on the yaw platform, since the cable cannot rotate with the yaw but can only twist, the cable will become entangled. If the cable guiding ring only contacts the cable, then with the long-term operation of the unit, the vibration of the unit will cause the cable guiding ring to sink, resulting in extrusion and wear of the lower cables. Content of the Utility Model

[0005] To solve the problems raised in the above background technique, the utility model provides an anti-sinking cable guiding structure for a wind turbine generator set to solve the problems that when the existing cable guiding ring is fixedly installed on the yaw platform, the cable will become entangled, and when the cable guiding ring only contacts the cable, it will sink itself.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] An anti-sinking cable guiding structure for a wind turbine generator set, comprising:

[0008] A sliding structure; the sliding structure is fixedly installed on the yaw platform, and at least one sliding end is provided on the sliding structure. Under the action of an external force, the sliding end makes a circular motion around the center of the cable hole of the yaw platform;

[0009] A cable guiding ring; the cable guiding ring is connected to the sliding end, the center of the cable guiding ring is coaxial with the center of the cable hole of the yaw platform, and at least one fixing through hole is provided on the cable guiding ring, and a cable is arranged in one fixing through hole.

[0010] Preferably, the sliding structure includes:

[0011] A ring-shaped universal hanger wheel guide rail; the ring-shaped universal hanger wheel guide rail is fixedly installed on the yaw platform;

[0012] At least one universal hanger wheel; the roller of the universal hanger wheel is slidably arranged on the ring-shaped guide rail, and the suspension rod of the universal hanger wheel is fixedly connected to the cable guiding ring.

[0013] Preferably, the anti-sinking cable guiding structure of the wind turbine generator further comprises at least one connecting rod. The first end of one connecting rod is fixedly connected to the boom of a universal hanger pulley, and the second end is fixedly connected to the cable guiding ring.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In this application, a sliding structure is provided. The sliding end of the sliding structure can make a circular motion around the center of the cable hole of the yaw platform under the action of an external force. The cable guiding ring is connected to the sliding end, and the center of the cable guiding ring coincides with the center of the cable hole. When the yaw platform rotates with the cable fixed, the cable guiding ring is stationary relative to the cable, and the cable will not get entangled. Moreover, since the sliding structure is fixedly installed on the yaw platform, the cable guiding ring connected to the sliding end of the sliding structure will not sink.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1:

[0021] As Figure 1 shown, an anti-sinking cable guiding structure of a wind turbine generator comprises:

[0022] A sliding structure; the sliding structure is fixedly installed on the yaw platform, and there are two sliding ends on the sliding structure. The sliding ends make a circular motion around the center of the cable hole of the yaw platform under the action of an external force;

[0023] A cable guiding ring 1; the cable guiding ring 1 is connected to the sliding end, the center of the cable guiding ring 1 and the center of the cable hole of the yaw platform are on the same vertical line, and there are sixteen fixing through holes on the cable guiding ring 1. A cable is arranged in one fixing through hole.

[0024] In this embodiment, the present application is provided with a sliding structure. The sliding end of the sliding structure can make a circular motion around the center of the cable hole of the yaw platform under the action of an external force. The cable guiding ring 1 is connected to the sliding end, and the center of the cable guiding ring 1 overlaps with the center of the cable hole. When the cable is fixed and the yaw platform rotates, the cable guiding ring 1 is stationary relative to the cable, and the cable will not be entangled. Moreover, since the sliding structure is fixedly installed on the yaw platform, the cable guiding ring 1 connected to the sliding end of the sliding structure will not sink.

[0025] Embodiment 2:

[0026] The difference between this embodiment and Embodiment 1 is that, as Figure 1 shown, the sliding structure includes:

[0027] A ring universal hanger wheel guide rail 2; the ring universal hanger wheel guide rail 2 is fixedly installed on the yaw platform;

[0028] Two universal hanger wheels 3; the rollers of the universal hanger wheels 3 are slidably arranged on the ring guide rail, and the suspension rods of the universal hanger wheels 3 are fixedly connected to the cable guiding ring 1.

[0029] In this embodiment, when the yaw platform rotates, the force that twists the cable will be transmitted to the universal hanger wheel 3, driving the universal hanger wheel 3 to roll in the ring universal hanger wheel guide rail 2. At this time, the cable guiding ring 1 is stationary relative to the cable, avoiding cable entanglement.

[0030] Embodiment 3:

[0031] The difference between this embodiment and Embodiment 2 is that, as Figure 1 shown, the anti-sinking cable guiding structure of the wind turbine generator is further provided with two connecting rods 4. The first end of one connecting rod 4 is fixedly connected to the suspension rod of one universal hanger wheel 3, and the second end is fixedly connected to the cable guiding ring 1. The two connecting rods 4 are symmetrically arranged with respect to the center of the cable guiding ring 1.

[0032] In this embodiment, since the diameter of the cable hole of the yaw platform is fixed, different lengths of connecting rods 4 can be replaced to adapt to different sizes of cable guiding rings 1 and universal hanger wheels 3.
