Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine generator sets, and specifically relates to an installation structure for a slip ring of a wind turbine generator set. Background Technology

[0002] The slip ring in the wind turbine drive chain system is a component that transmits the power current and electrical signals from the stationary end to the rotating end of the system. The slip ring rotor is connected to the hollow shaft of the gearbox through a bearing assembly, and the mounting structure currently mainly achieves mounting support through the bearing assembly.

[0003] The patent disclosed in CN221177485U is an installation structure for a slip ring of a wind turbine generator set and a wind turbine generator set. This patent achieves the installation of the slip ring by eliminating the bearing assembly and supporting it with an adapter bracket. However, this installation structure is an integral part and cannot be adjusted. The position and size of the slip ring in different wind turbine generator sets are also different. Therefore, there may be a problem of size mismatch during installation, and the overall universality is poor. Therefore, there is room for improvement in actual use. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for the slip ring of a wind turbine generator set, so as to solve the problem of poor versatility of the existing installation structure mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for a slip ring of a wind turbine generator set, comprising a flange plate with a hole on its surface that is fitted onto the hollow shaft of the wind turbine generator gearbox, and through holes formed around the hole; it also includes two angle steels arranged symmetrically along the center of the flange plate; the angle steels are in contact with the plane of the flange plate, and an adjustment groove is formed on the end face of the angle steels facing the flange plate; an adjustment assembly is composed of an adjustment member and a limiting member, wherein one end of the adjustment member is fixed to the flange plate, and the other end passes through the adjustment groove and extends to the inner area of ​​the angle steel; the limiting member is fitted onto the other end of the adjustment member, and the limiting member abuts against the end face of the angle steel. In use, the position of the angle steel is adjusted by the adjustment member, and when it is adjusted to a suitable position, the angle steel is locked onto the flange plate by the limiting member, thereby achieving fixation and enabling corresponding adjustments according to the slip ring.

[0006] Preferably, the adjusting component includes a screw with a diameter smaller than the inner diameter of the adjusting groove, so that the angle steel can move in any direction on the surface of the flange plate without contacting the screw.

[0007] Preferably, the limiting component includes a limiting plate sleeved on the screw and a locking nut sleeved on the screw. The locking nut abuts against the limiting plate, and the limiting plate abuts against the inner wall of the angle steel. The length of the limiting plate is greater than the inner diameter of the adjusting groove. After the angle steel is adjusted to a suitable position, the locking nut is tightened. The locking nut will drive the limiting plate to move toward the angle steel, thereby ensuring that the limiting plate and the angle steel are tightly abutted.

[0008] Preferably, the end side of the angle steel is provided with a movable groove, the end of the limiting plate moves through the movable groove, and the inner width of the movable groove is greater than the thickness of the limiting plate, so that after the angle steel is adjusted, the limiting plate and the angle steel are not in a tight abutment state, ensuring that the limiting plate can move in the movable groove.

[0009] Preferably, the inner side of the angle steel is also provided with a protective pad, and a metal plate is fixed to the side of the protective pad facing the angle steel. The angle steel has a slot for the metal plate to pass through, and the through end of the metal plate is bent and limited to the outer side of the angle steel. The protective pad provides buffer protection, and the metal plate provides a stable installation with the angle steel to prevent it from falling off.

[0010] Preferably, an annular groove is provided at the end face of the flange away from the angle steel, and a sealing ring is inserted into the annular groove to achieve sealing after connection.

[0011] Preferably, the sealing ring protrudes to the outside of the flange plate to achieve a tight seal, and the end section of the sealing ring is circular.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing this utility model, the existing integrated installation structure is changed to a form in which the positions of each component are adjusted, thereby meeting the installation limit requirements of slip rings of different specifications, greatly improving the versatility of the installation structure, and the entire adjustment process is very convenient and easy to use, thus overcoming the shortcomings of the existing structure in use.
