Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a wind turbine cable winding structure. Background Technology

[0002] Wind turbines, as a model of modern renewable energy technology, mainly consist of core components such as a wind turbine, generator, deflector, tower, speed limiting safety mechanism, and energy storage device. They capture wind energy through the turbine, converting it into mechanical energy, which then drives the generator to produce clean electricity. These generators, based on different designs such as doubly-fed with multi-stage speed-increasing gearboxes, direct-drive without speed-increasing gearboxes, or semi-direct-drive with a single-stage speed-increasing gearbox, achieve efficient conversion from wind energy to electricity. Furthermore, wind turbines are divided into constant-speed constant-frequency and variable-speed constant-frequency types to adapt to power generation needs under different wind speed conditions, and can employ various motor types such as squirrel-cage induction generators, wound-rotor doubly-fed induction generators, or permanent magnet synchronous generators to optimize power generation efficiency. Wind power generation, with its renewable, environmentally friendly, and economical characteristics, has been widely used globally, especially in western my country, where it has become an important energy supply method. With continuous technological advancements and further cost reductions, wind power generation is expected to play an even more crucial role in the energy sector, promoting the green transformation of the global energy structure. The yaw mechanism is a crucial component of a wind turbine, responsible for ensuring that the turbine's rotor always faces the wind to maximize wind energy capture and conversion into electricity. This device uses precise sensors to monitor wind direction changes and drives the turbine's tower or rotor to rotate at the corresponding angle, ensuring the rotor is always in the optimal windward position. The presence of the yaw mechanism not only improves the power generation efficiency of the wind turbine but also enhances its stability and reliability under complex and changing wind conditions.

[0003] During the yaw rotation, the cables on the wind turbine also rotate. During this rotation, the cables are easily damaged due to the tightening of the rotary knob or dragging. Damaged cables can have a significant impact on the wind turbine, so cable protection is necessary. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a wind turbine cable winding structure, including a column assembly with a cable tray fixedly mounted on it. The cable is wound inside the cable tray and is in a slack state. Through this technical solution, the cable can be adjusted by tightening and loosening the winding during yaw rotation of the wind turbine, preventing cable breakage and improving the service life of the wind turbine.

[0005] Furthermore, the cable tray is provided with a cable outlet, which is located near the column assembly.

[0006] Furthermore, a protective ring is rotatably mounted on the outer side of the cable tray to prevent the cable drag chain from detaching from the tray during winding. Through this technical solution, the cable drag chain can protect the cable, preventing wear during loosening or tightening, and improving the cable's service life.

[0007] Furthermore, the protective ring is equipped with a wire inlet located at the edge of the cable tray. Through this technical solution, the cable has fixed wire inlets and outlets, ensuring that the cables do not become tangled together and facilitating cable management and maintenance.

[0008] Furthermore, the cable tray contains a cable drag chain, and the cable is protected within the cable drag chain.

[0009] Furthermore, a maintenance platform is mounted on the column assembly, and a connecting pipe is fixed between the maintenance platform and the cable tray guard ring. The cable is connected downwards through the inlet and outlet of the cable.

[0010] Furthermore, the maintenance platform is fixedly connected to the cable tray guard ring, and when the cable and the maintenance platform rotate together for one revolution, the cable drag chain is in a tightly wound state.

[0011] The advantages of this utility model compared with the prior art are:

[0012] (1) When the wind turbine is yawed, the cable is wound tightly or loosely in the cable tray with enough slack. When it is wound tightly, it takes one rotation to tighten the cable. However, the yaw adjustment does not rotate one rotation, so it does not damage the cable. Through the above technical solution, when the wind turbine is yawed, the cable can be adjusted by winding it tightly or loosely to prevent the cable from breaking and to improve the service life of the wind turbine.

[0013] (2) The inlet wire is connected to both the maintenance platform and the cable tray guard ring, which can ensure that the maintenance platform and the cable rotate synchronously and protect the cable when it enters, preventing wear on the cable during rotation. Through the above technical solution, the cable has a fixed inlet wire and outlet, ensuring that the cable will not get tangled together, making it easier to sort and maintain the cable.

[0014] (3) The cable drag chain has sufficient space inside to accommodate the cable, and the cable drag chain can also be wound. Through the above technical solution, the cable drag chain can protect the cable and will not cause wear during the winding process, thus improving the service life of the cable. At the same time, a protective ring is fixedly installed on the outside of the cable tray to prevent the cable drag chain from falling off the cable tray. Attached Figure Description

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-4 The diagram illustrates a wind turbine cable winding structure mounted on a column assembly 1. A mounting gantry 10 is fixedly mounted on the lower side of the column assembly 1, and a mounting flange 9 is fixedly mounted on the mounting gantry 10. The mounting flange 9 is fixedly connected to the column assembly 1. A maintenance platform 5 is rotatably connected to a protective ring 4. A platform railing 11 is installed on the maintenance platform 5 for protection. In this embodiment, a cable reel tray 2 is fixedly mounted on the column assembly 1, and the cable is wound inside the cable reel tray 2 in a slack state. When the wind turbine adjusts its yaw, the cable is wound tightly or loosely within the cable reel tray 2, with sufficient slack. When tightening, a full rotation is required to tighten the cable, while yaw adjustment does not involve a full rotation, thus preventing damage to the cable. Through this technical solution, the cable can be adjusted by tightening and loosening during yaw rotation, preventing cable breakage and improving the service life of the wind turbine.

[0022] The cable tray 2 is equipped with a cable outlet 8, which is located near the column assembly 1. When the cable is adjusted for yaw, it rotates, while the cable tray 2 remains stationary. Therefore, the inlet cable 3 needs to be placed on the rotatable protective ring 4, and the protective ring 4 can rotate with it. This not only protects the inside of the cable tray 2 but also does not affect the yaw rotation.

[0023] The protective ring 4 is equipped with a cable inlet 3, and the support assembly 1 is equipped with a maintenance platform 5. A connecting pipe 7 is fixedly installed between the maintenance platform 5 and the cable tray protective ring 4. The cable is connected downwards through the cable inlet 3 and the cable outlet 8. The cable enters the protective ring 4 through the cable inlet 3, which not only ensures that the maintenance platform 5 and the cable tray 2 rotate synchronously, but also protects the cable and prevents wear and tear during rotation. Through the above technical solution, the cable has a fixed cable inlet 3 and cable outlet 8, ensuring that the cable will not get tangled together, making it easier to manage and maintain the cable.

[0024] The cable tray 2 contains a cable drag chain 6, protecting the cable within it. A protective ring 4 is fixed to the outside of the cable tray 2, and a maintenance platform 5 is connected to the protective ring 4. When the maintenance platform 5 rotates one revolution, the cable drag chain 6 is in a tightly wound state. Sufficient clearance is provided inside the drag chain to accommodate the cable, and the drag chain can also be wound. Through this technical solution, the cable drag chain 6 can protect the cable, preventing wear during loosening or tightening, thus improving the cable's service life.

[0025] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
