The guide groove is formed in the outer shell of the generator and matched with the bolt hole in the elastic supporting seat, the elastic supporting seat slides along the guide groove to adjust the distance, the installation of fan rear underframes of different models is adapted, and the installation time and cost are saved; the boss on the lower side face of the generator shell and the guide groove form height difference, enough space is provided for installing the elastic supporting base on the lower side face of the generator shell, the installation space is large, and convenience and rapidness are achieved. As the rectangular groove and the guide groove are vertically intersected with each other, even if errors exist in the mounting process, the bolts cannot be influenced to penetrate through the rectangular groove and the guide groove, the mounting is convenient and fast, and the errors existing in the machining process can be eliminated; due to the fact that a certain interval exists between the lower side face of the generator outer shell and the rectangular groove, after the bolt penetrates through the rectangular groove and the guide groove, the bolt is elastically connected in the fastening process, and the anti-loosening effect is achieved.

Description

Technical Field

[0001] This utility model belongs to the field of wind turbine base connection technology, and relates to a wind turbine generator elastic support base connection structure with adjustable span. Background Technology

[0002] Currently, most flexible support seats for generator sets have a fixed span and are connected to the generator support on the rear base frame via bolts. The publication / announcement number CN203604123U, entitled "An Adjustable Flexible Support Component for Wind Turbine Generators with Limiters," employs an adjustable flexible support structure for wind turbine generators. Limiters restrict the span, meaning the horizontal support span cannot be changed. Another problem is that the span of the generator support on the rear base frame varies depending on the wind turbine model. Installing the generator on the rear base frame requires adjusting the span of the flexible support seat or the generator support on the rear base frame in the design, increasing design costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a wind turbine generator elastic support base connection structure with adjustable span. A guide groove is set on the generator housing to cooperate with the bolt holes on the elastic support base. The elastic support base slides along the guide groove to adjust the distance, which can adapt to the installation of the rear base frame of different models of wind turbines, saving installation time and cost.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a wind turbine generator elastic support base connection structure with adjustable span, which includes a generator housing and elastic support bases; two mutually symmetrical and parallel guide grooves are provided on both sides of the generator housing along the horizontal direction; multiple elastic support bases are located on the lower side of the generator housing and connected to it, and slide along the guide grooves, and the distance between every two elastic support bases is adjustable.

[0005] The generator housing is a flat plate structure, with downward-protruding bosses located between the guide grooves on the lower side.

[0006] The elastic support base is a flat plate with multiple bolt holes on one side that mate with the guide groove, and a through rectangular groove on the other side.

[0007] The rectangular groove and the guide groove intersect each other perpendicularly.

[0008] The bolt holes and rectangular grooves are located on the same surface of the elastic support, forming a height difference, and the rectangular grooves do not contact the generator housing.

[0009] The main beneficial effects of this utility model are as follows:

[0010] By setting guide grooves on the generator housing and matching them with bolt holes on the elastic support, the elastic support slides along the guide grooves to adjust the distance, adapting to the installation of the rear base frame of different models of wind turbines, saving installation time and costs.

[0011] The boss on the lower side of the generator housing and the guide groove form a height difference, providing sufficient space to install the elastic support on the lower side of the generator housing. The installation space is large, convenient and quick.

[0012] Since the rectangular groove and the guide groove intersect each other perpendicularly, even if there are errors during the installation process, it will not affect the bolts passing through the rectangular groove and the guide groove, making installation convenient and quick, and eliminating errors in the processing.

[0013] Because there is a certain gap between the lower side of the generator housing and the rectangular groove, when the bolt passes through the rectangular groove and the guide groove, the bolt forms an elastic connection during the tightening process, which has the effect of preventing loosening.

[0019] In the figure: generator housing 1; guide groove 11; boss 12; elastic support 2; bolt hole 21; rectangular groove 22. Detailed Implementation

[0020] like Figures 1-4 A wind turbine generator elastic support connection structure with adjustable span is disclosed. It includes a generator housing 1 and elastic support seats 2. Two symmetrical and parallel guide grooves 11 are provided on both sides of the generator housing 1 along the horizontal direction. Multiple elastic support seats 2 are located on the lower side of the generator housing 1 and connected to it, sliding along the guide grooves 11. The distance between any two elastic support seats 2 is adjustable. By providing guide grooves 11 on the generator housing 1 that engage with bolt holes 21 on the elastic support seats 2, the elastic support seats 2 can slide along the guide grooves 11 to adjust the distance, adapting to the installation of different types of wind turbine rear frames, saving installation time and costs.

[0021] In a preferred embodiment, the generator housing 1 has a flat plate structure, with downwardly protruding bosses 12 located between the guide grooves 11 on the lower side. During use, the bosses 12 on the lower side of the generator housing 1 and the guide grooves 11 form a height difference, providing sufficient space to install the elastic support 2 onto the lower side of the generator housing 1. This provides ample installation space and is convenient and quick.

[0022] In a preferred embodiment, the elastic support 2 is a flat plate with multiple bolt holes 21 on one side that mate with the guide groove 11, and a through rectangular groove 22 on the other side. In use, bolts are passed through the bolt holes 21 and the guide groove 11 to connect them into a single unit.

[0023] Preferably, before the bolts are tightened, the elastic support 2 is pushed to the mounting position of the rear base of different types of fans, making the adjustment convenient and quick.

[0024] In a preferred embodiment, the rectangular groove 22 and the guide groove 11 intersect each other perpendicularly. During use, because the rectangular groove 22 and the guide groove 11 intersect each other perpendicularly, even if there are errors during installation, it will not affect the bolt passing through the rectangular groove 22 and the guide groove 11, making installation convenient and quick, and eliminating errors present in the processing.

[0025] In a preferred embodiment, the bolt hole 21 and the rectangular groove 22 are located on the same surface of the elastic support 2, forming a height difference, and the rectangular groove 22 does not contact the generator housing 1. During use, because there is a certain gap between the lower side of the generator housing 1 and the rectangular groove 22, when the bolt passes through the rectangular groove 22 and the guide groove 11, the bolt forms an elastic connection during the tightening process, providing an anti-loosening effect.

[0026] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
