Description

Technical Field

[0001] This utility model relates to the field of wind power generation, specifically to the limit switch bracket of the pitch system of a 2MW horizontal axis wind turbine. Background Technology

[0002] In traditional 2MW horizontal axis wind turbine pitch control systems, limit switches always appear in pairs, i.e., two limit switches. The traditional mounting method is one limit switch per bracket, which is time-consuming and labor-intensive. Furthermore, although the limit switches are paired, their heights are not fixed. This means that each time limit switches are installed, two brackets of matching height must be found for each pair of switches, and then they must be installed. The total time spent on this setup far exceeds that of limit switches in other equipment. To address this, we need a new structure that saves materials and improves efficiency.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0004] The purpose of this invention is to provide a limit switch bracket for a 2MW horizontal axis wind turbine pitch system, so as to overcome the above-mentioned shortcomings and deficiencies of the prior art.

[0005] A limit switch bracket for a 2MW horizontal axis wind turbine pitch system includes: a fixed bracket, limit switch mounting holes, position adjustment holes, and an adjustment bracket. The fixed bracket has a U-shaped structure. The top of the fixed bracket is provided with a limit switch mounting hole, and the fixed bracket is connected to the limit switch through the limit switch mounting hole. The fixed bracket has vertically aligned position adjustment holes on both sides. There are multiple position adjustment holes, and the fixed bracket is connected to the adjustment bracket through the position adjustment holes. The bottom of the adjustment bracket is fixed to the mounting position with bolts.

[0006] Furthermore, the limit switch mounting hole includes: a first limit switch mounting hole and a second limit switch mounting hole, the first limit switch mounting hole and the second limit switch mounting hole are symmetrically arranged at the top of the fixed bracket, and the first limit switch mounting hole and the second limit switch mounting hole are respectively connected to the mounting base of the limit switch.

[0007] The beneficial effects of this utility model are:

[0008] Compared with traditional technology, this utility model uses a separate fixed bracket to fix the two limit switches, and at the same time sets a vertical alignment adjustment hole. The height of the entire bracket can be adjusted through different connections. Attached Figure Description

[0013] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0014] Example 1

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] like Figure 1 As shown, the limit switch bracket for the pitch system of a 2MW horizontal axis wind turbine includes: a fixed bracket 100, a limit switch mounting hole 200, a position adjustment hole 300, and an adjustment bracket 400. The fixed bracket 100 has a U-shaped structure. The top of the fixed bracket 100 is provided with the limit switch mounting hole 200. The fixed bracket 100 is connected to the limit switch 500 through the limit switch mounting hole 200. The fixed bracket 100 has vertically aligned position adjustment holes 300 on both sides. There are multiple position adjustment holes 300. The fixed bracket 100 is connected to the adjustment bracket 400 through the position adjustment holes 300. The bottom end of the adjustment bracket 400 is bolted to the mounting position 600.

[0017] The limit switch mounting hole 200 includes a first limit switch mounting hole 210 and a second limit switch mounting hole 220. The first limit switch mounting hole 210 and the second limit switch mounting hole 220 are symmetrically arranged at the top of the fixed bracket 100. The first limit switch mounting hole 210 and the second limit switch mounting hole 220 are respectively connected to the mounting base of the limit switch 500.

[0018] The innovation of this utility model is that it uses a single limit switch bracket instead of two traditional limit switch brackets, saving bracket costs and installation time. The principle is as follows: a fixed bracket 100 is designed, and then two limit switch mounting holes 200 are opened at the top of the fixed bracket: a first limit switch mounting hole 210 and a second limit switch mounting hole 220. The mounting bases of the limit switches 500 are then connected to the first limit switch mounting hole 210 and the second limit switch mounting hole 220 respectively, thus fixing the two limit switches 500 to the fixed bracket 100. Next, a bracket of suitable height needs to be found. First, an adjusting bracket 400 is fixed at the installation position 600. Then, the height of the limit switches 500 is adjusted according to a preset height. The limit switches 500 will then adjust the height of the entire fixed bracket 100. During this process, the position adjustment hole 300 on the fixed bracket 100 connects with the corresponding mounting hole on the adjusting bracket 400 to complete the fixation. In other words, in this embodiment, the two sets of six vertically arranged position adjustment holes 300 can be connected to the mounting holes of the adjustment bracket 400 at different positions according to the actual height to achieve the position adjustment of this utility model.

[0019] This invention achieves precise control over the installation height of the limit switch through a modular bracket structure and a flexible hole adjustment mechanism. This height-adjustable design not only improves installation efficiency but also enhances the overall performance and reliability of the system. By reducing the number of brackets and optimizing installation steps, this invention lowers manufacturing costs while also reducing human error during installation, reflecting the dual pursuit of efficiency and precision in modern engineering design.

[0020] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
