[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] This embodiment provides a wind turbine mounting device for wind tunnel testing, such as... Figure 1 and Figure 2 As shown, it includes:

[0038] The rectangular frame 1 is composed of several supports 11, and the whole is a rectangular hollow frame. In this embodiment, it is a rectangular frame structure composed of twelve supports.

[0039] The X-axis slide rail assembly 2 is mounted on four parallel supports 11 within the rectangular frame;

[0040] The Y-axis slide rail assembly 3 is connected to the X-axis slide rail assembly 2 via a locking mechanism, and the Y-axis slide rail assembly 3 translates along the X-axis slide rail assembly 2;

[0041] Z-axis slide rail assembly 4 is connected to Y-axis slide rail assembly 3 via a locking mechanism, and Z-axis slide rail assembly 4 translates along Y-axis slide rail assembly 3;

[0042] Mounting platform 5 is set on the Z-axis slide rail assembly 4 and is used to fix the fan to be tested;

[0043] Multiple locking mechanisms 6 are provided at each slide rail assembly to fix the relative position of the slider in the slide rail assembly.

[0044] Specifically, the X-axis slide rail assembly 2 includes four X-axis linear slide rails 21, which are respectively mounted on four parallel supports 11 within the rectangular frame, and all are positioned above the supports. Each X-axis linear slide rail 21 is provided with an X-axis slider 22, which slides in cooperation with the X-axis linear slide rail 21.

[0045] The Y-axis slide rail assembly 3 includes two parallel Y-axis linear slide rails 31. The two sides of each Y-axis linear slide rail 31 are fixedly connected to the X-axis slider 22 in the X-axis slide rail assembly 2. Two Y-axis sliders 32 are provided on each Y-axis linear slide rail 31, and each Y-axis slider 32 slides in cooperation with the Y-axis linear slide rail 31.

[0046] The Z-axis slide rail assembly 4 includes two parallel Z-axis linear slide rails 41, which are positioned between the two Y-axis linear slide rails 31 of the Y-axis slide rail assembly 3. Each Z-axis linear slide rail 41 has its two sides fixedly connected to a Y-axis slider 32 in the Y-axis slide rail assembly 3. A Z-axis slider 42 is mounted on each Z-axis linear slide rail 41, and the Z-axis slider 42 slides in cooperation with the Z-axis linear slide rail 41. Furthermore, the two ends of each Z-axis linear slide rail 41 are respectively fixedly connected to the Y-axis sliders 32 on the two Y-axis linear slide rails 31, making the distance between the two Z-axis linear slide rails 41 adjustable.

[0047] The Y-axis slide rail assembly and Z-axis slide rail assembly may also include connecting rods. First, connect the connecting rods to the corresponding sliders, and then set the linear slide rails on the connecting rods. Of course, the two ends of the linear slide rails can also be directly fixed to the sliders. The choice can be made according to different setting scenarios, which will not be elaborated here.

[0048] For locking and fixing the slider on the linear guide rail, you can directly drill a screw hole (or through hole) in the slider and then pass a bolt through to lock the slider.

[0049] To further improve the fastening effect, in an optional embodiment, the locking mechanism 6 includes a clamping block 63 and a locking bolt 62. Threaded holes 61 are provided on the side of the slider in each slide rail assembly. The clamping block 63 is locked to the side of the slider by the locking bolt 62 and the threaded holes 61. The lower side of the clamping block 63 abuts against the linear slide rail or the bracket 11 to lock the slider onto the linear slide rail. The clamping block 63 can be made of rubber, or an arc-shaped contact surface can be provided on the lower part of the clamping block 63, with a flexible damping pad placed on this contact surface. After the slider position is adjusted, the locking mechanism 6 can lock the slider and the linear slide rail relative to each other, preventing the slider from moving during testing.

[0050] The mounting platform 5 includes an L-shaped mounting plate 51 disposed on the Z-axis slider 42 of the Z-axis slide rail assembly 4. Multiple fixing screw holes 52 are provided on the mounting plate 51. The fan to be tested is fixedly connected to the mounting plate by screws to the fixing screw holes 52. One, two, or more Z-axis sliders 42 can be set on the Z-axis linear slide rail 41 as needed, and mounting plates are then set on each Z-axis slider 42. Thus, by simply adjusting the position of the Z-axis slider 42, it can be adapted to the installation position of fans of different specifications.

[0051] As an optional solution, a position scale 7 is provided along the length of each slide rail assembly. The position scale 7 is located next to each slide rail assembly and is used to indicate the movement distance of the slider in the slide rail assembly.

[0052] Optionally, a support 12 is provided at the bottom of the rectangular frame 1, and a leveling foot 8 is provided at the bottom of the support 12 to adjust the overall level of the rectangular frame 1.

[0053] In summary, the wind turbine fixing device of this application is suitable for wind tunnel testing. This device uses a combination structure of slide rails, sliders, and support frame assembly, which allows the fixed position of the wind turbine to be adjusted along the X-axis, Z-axis, and Y-axis. This allows the wind turbine to move freely in three degrees of freedom within the device's limits. Thus, using this device facilitates wind turbine installation. To address the difficulty of installing non-standard wind turbines, the size of the installation position can be adjusted to accommodate the installation, allowing the wind turbine to move in three degrees of freedom and be fixed in a suitable position during wind tunnel testing. This effectively improves testing efficiency while reducing the cost of testing equipment.
