Description

Technical Field

[0001] This utility model relates to the field of bracket installation structure technology, and in particular to a wind turbine wind measurement mounting bracket. Background Technology

[0002] The wind measurement components on a wind turbine mainly include an anemometer, wind vane, wind sensors, and related data processing and transmission equipment. These components work together to provide accurate wind speed and wind direction data for the wind turbine.

[0003] Its anemometer, wind vane, and wind sensor are all mounted on a support structure. Currently, the nacelle is equipped with mounting slots and pre-drilled holes, and threaded connections are also installed within the mounting slots. These mounting slots are connected to the nacelle to enable data transmission (see appendix for details). Figure 4 However, the current support structure is too simple, with only a single support part and nacelle bolt fixation, lacking auxiliary reinforcement components. Even after installation into the mounting slot and pre-set mounting hole, it will still loosen and allow water vapor to enter due to external factors. Since the maintenance and repair of wind turbine units is relatively difficult, we propose a wind turbine unit wind measurement mounting bracket. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by appropriately modifying the layout of the mounting slots, preset mounting holes, and threaded connections within the mounting slots on existing engine nacelles. This results in a new type of bracket that ensures the installation stability of the wind measurement components and reduces the problems of loosening and moisture ingress.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wind turbine wind measurement mounting bracket includes a bracket and a mounting base. The bracket is disposed on the top of the mounting base, a rain cover is fitted around the bracket, and a threaded mounting rod is provided at the bottom of the mounting base.

[0007] The mounting base is fitted with an anti-sway washer near the upper part of its outer periphery;

[0008] The rain cover is larger than the mounting base, and a sealing gasket is adhered to the bottom of the rain cover;

[0009] The mounting base and the rain cover are respectively provided with a number of first mounting holes and second mounting holes around the perimeter.

[0010] Furthermore, a secondary bracket is installed at the end of the bracket away from the mounting base. The secondary bracket has two vertically symmetrically installed on the outer wall of the bracket for the installation of the wind measurement component.

[0011] Furthermore, the sub-support, support, mounting base, and threaded mounting rod are connected together, and the threaded mounting rod is connected to the nacelle for connecting the wind measurement component circuit.

[0012] Furthermore, the mounting base is adapted to the bracket mounting slot on the engine compartment, and the rain cover is larger than the bracket mounting slot on the engine compartment.

[0013] Furthermore, the threaded mounting rod is threaded into the threaded groove within the bracket mounting slot on the engine compartment.

[0014] Furthermore, the anti-sway washer is fitted into an annular groove near the upper part of the outer periphery of the mounting base. The size of the anti-sway washer is larger than the bracket mounting groove on the nacelle. The anti-sway washer is pressed into the bracket mounting groove.

[0015] Furthermore, both the first and second mounting holes are two embedded mounting holes, which are fixedly connected to the pre-set mounting holes on the nacelle by bolts. The first mounting hole is connected to the pre-set mounting hole in the bracket mounting groove, while the second mounting hole is connected to the pre-set mounting hole on the nacelle outside the bracket mounting groove.

[0016] Furthermore, a rubber ring is provided between the rain cover and the bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By adding a rain cover and sealing gaskets and rubber rings, moisture can be effectively prevented from entering, thus avoiding damage to internal components due to moisture intrusion.

[0019] Anti-sway washers are installed around the mounting base. After being squeezed into the mounting groove of the bracket, the bracket is prevented from shaking due to gaps. The threaded mounting rod is connected to the nacelle thread, and the first and second mounting holes are fixedly connected to the preset mounting holes of the nacelle. This enhances the overall installation stability of the bracket, reduces the risk of bracket loosening, ensures the stable operation of the wind measurement component, and reduces the maintenance and repair needs of the wind turbine due to problems with the wind measurement mounting bracket.

[0034] Example 1

[0035] like Figure 1-4As shown, this utility model provides a technical solution: a wind turbine wind measurement mounting bracket, which mainly consists of a bracket 1 and a mounting base 2 forming the core structure. The bracket 1 is stably set on the top of the mounting base 2, providing a support foundation for the installation of the wind measurement component. A rain cover 3 is fitted around the bracket 1. The rain cover 3 is larger than the mounting base 2, and a sealing gasket 31 is glued to its bottom. When the sealing gasket 31 is pressed against the nacelle, it can effectively block external rainwater and prevent moisture from entering the interior of the mounting bracket, thus avoiding damage to internal components due to moisture. The bottom of the mounting base 2 is provided with a threaded mounting rod 4 for initial threaded connection and fixation with the nacelle.

[0036] An anti-sway washer 21 is fitted around the upper part of the outer periphery of the mounting base 2. The anti-sway washer 21 can reduce the gap between the mounting bracket and the bracket mounting groove. The mounting base 2 and the rain cover 3 are respectively surrounded by a number of first mounting holes 5 and second mounting holes 6. These mounting holes provide dual connection points for further fixing of the mounting bracket to the cabin.

[0037] Example 2

[0038] like Figure 1-4 As shown, based on Embodiment 1, a secondary bracket 11 is installed at the end of the bracket 1 away from the mounting base 2. The secondary bracket 11 has two members that are vertically and symmetrically installed on the outer wall of the bracket 1. It is specifically used for the installation of the wind measurement component, so that the wind measurement component can be stably placed on the mounting bracket.

[0039] The auxiliary bracket 11, bracket 1, mounting base 2 and threaded mounting rod 4 are interconnected, and the threaded mounting rod 4 is connected to the nacelle. This interconnection design provides a convenient channel for the wiring connection of the wind measurement component, making it easy for the wind measurement component to transmit the collected data to the relevant equipment in the nacelle.

[0040] Mounting base 2 is sized to fit the bracket mounting slot on the nacelle. Rain cover 3 is larger than the bracket mounting slot on the nacelle to ensure complete coverage of the mounting slot and further enhance waterproofing. Threaded mounting rod 4 is threaded into the threaded groove in the bracket mounting slot on the nacelle to achieve a preliminary and stable connection.

[0041] The anti-sway washer 21 is fitted into the annular groove 22 opened near the upper part of the outer periphery of the mounting base 2. The size of the anti-sway washer 21 is larger than the bracket mounting groove on the nacelle. During installation, the anti-sway washer 21 is squeezed into the bracket mounting groove to effectively prevent the mounting bracket from shaking and ensure long-term stability.

[0042] The first mounting hole 5 and the second mounting hole 6 are both embedded mounting holes, which are fixedly connected to the pre-set mounting holes on the engine compartment by bolts. The first mounting hole 5 is connected to the pre-set mounting hole in the mounting groove of the bracket, while the second mounting hole 6 is connected to the pre-set mounting hole on the engine compartment outside the mounting groove of the bracket. This double fixing method greatly enhances the connection stability between the mounting bracket and the engine compartment. A rubber ring 32 is provided between the rain cover 3 and the bracket 1 to further improve the sealing performance and prevent moisture from seeping into the sealing gasket 31 from the connection between the rain cover 3 and the bracket 1.

[0043] The workflow of this utility model is as follows: When using a wind turbine wind measurement mounting bracket, first align the threaded mounting rod 4 at the bottom of the mounting base 2 with the threaded groove in the mounting slot of the bracket on the nacelle, and slowly rotate the mounting base 2 to make the threaded mounting rod 4 tightly threadedly connected with the threaded groove, thus completing the initial positioning and fixing of the mounting bracket to the nacelle.

[0044] Next, the anti-sway washer 21 is inserted into the annular groove 22 near the upper part of the outer periphery of the mounting base 2. Then, the mounting base 2 is pressed hard to make the anti-sway washer 21 snap into the bracket mounting groove on the nacelle. The elastic deformation and size advantage of the anti-sway washer 21 are used to enhance the stability of the mounting bracket and reduce swaying.

[0045] Then, using bolts, the first mounting hole 5 is connected to the pre-set mounting hole in the bracket mounting groove;

[0046] Meanwhile, the wind measurement component is installed on the sub-support 11 to ensure that the wind measurement component is firmly installed. The wiring of the wind measurement component is connected to the relevant equipment in the cabin through the connecting channel of the sub-support 11, support 1, mounting base 2 and threaded mounting rod 4 to ensure smooth data transmission.

[0047] The rain cover 3 on the periphery of the movable bracket 1 has a sealing gasket 31 at its bottom that fits tightly against the top of the mounting base 2. At the same time, it ensures that the rubber ring 32 between the rain cover 3 and the bracket 1 is also in the correct position, so as to play a sealing role and prevent moisture from entering.

[0048] Finally, using bolts, connect the second mounting hole 6 to the pre-set mounting hole on the outer side of the nacelle of the bracket mounting slot. Secure the bracket to the nacelle with double bolts to ensure a stable connection. This completes the entire installation process, and the wind turbine wind measurement mounting bracket can now be put into normal use, providing stable and reliable wind speed and direction data support for the wind turbine.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
