Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine components, and more specifically to a mounting bracket for a lidar system on a wind turbine generator set. Background Technology

[0002] Wind power generation, as an important renewable energy technology, has attracted much attention due to its large reserves and wide distribution. In wind turbine generators, lidar, as an advanced measurement tool, plays a crucial role. Lidar, based on the Doppler effect, accurately measures wind speed and direction by emitting a laser beam and receiving the returned scattered light signal. To improve the accuracy and stability of measurements, lidar is typically mounted on a specific bracket. This bracket ensures that the lidar is securely fixed in the appropriate position on the wind turbine generator, thereby guaranteeing the reliability of the measurement data.

[0003] Currently, lidar brackets are usually designed as an integrated structure, which is simple and reliable, but lacks flexibility and makes it inconvenient to control the angle and height of the lidar. Therefore, it requires high installation precision and is not conducive to installing other detection components around the lidar later, resulting in poor expandability. Utility Model Content

[0004] To address the technical problems existing in current lidar mounting brackets, this utility model proposes a lidar mounting bracket for wind turbine generator sets, comprising:

[0005] A pair of brackets for connecting to the top of the generator set, each of the brackets having its length direction parallel to the wind turbine axis;

[0022] The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component shown in the various figures may be denoted by the same reference numeral. For clarity, not every component is labeled in each figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:

[0023] Figure 1 This is a schematic diagram of the structure of the lidar mounting bracket for the wind turbine generator set shown in this utility model;

[0024] Figure 2 This is a front view of the lidar mounting bracket for a wind turbine generator set shown in this utility model. Detailed Implementation

[0025] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 and Figure 2 As shown, this utility model proposes a lidar mounting bracket for a wind turbine generator set, including a pair of brackets 10, a pair of columns 20, a crossbar 30, a support platform 40, and a mounting platform 50. The pair of brackets 10 are used to connect to the top of the generator set.

[0027] It should be understood that a bracket 101 is provided at the top of the generator set 100, and the bracket 10 can be connected to the bracket 101 by bolts.

[0028] Furthermore, each support 10 has a pair of columns 20 parallel to the wind turbine axis in its length direction, the bottom end of each column 20 is connected to the support 10, the crossbar 30 is detachably connected to the column 20, and the support platform 40 is connected to the crossbar 30.

[0029] Since the support bracket 10 is arranged along the wind turbine axis, the column 20 can be adjusted in position along the length direction. At the same time, the crossbar 30 can be adjusted in position relative to the top of the generator set 100 in the height direction. Through these two adjustments, the position of the mounting platform 50 above the support platform 40 can be flexibly adjusted to ensure that the lidar installed on the mounting platform 50 is not blocked by the front end of the wind turbine.

[0030] Furthermore, three height adjustment components are provided below the mounting platform 50, with the first end of each height adjustment component connected to the support platform 40 and the second end connected to the mounting platform 50.

[0031] Thus, by controlling the length of any height adjustment component, the mounting platform 50 and the support platform 40 can form a predetermined angle to ensure that the lidar installed on the mounting platform 50 meets the usage requirements.

[0032] Combination Figure 1 As shown, the bracket 10 is provided with a plurality of first waist-shaped holes 13, and the plurality of first waist-shaped holes 13 are arranged along the length direction of the bracket. The length direction of each waist-shaped hole is also along the length direction of the bracket 10. The column 20 is connected to the first waist-shaped holes 13. The column 20 is provided with a plurality of second waist-shaped holes 23. The crossbar 30 is connected to the second waist-shaped holes 23. The plurality of second waist-shaped holes 23 are along the height direction of the column 20, and the length direction of each second waist-shaped hole 23 is also along the height direction of the column 20.

[0033] In this way, a larger adjustable range is formed in the length direction of the bracket 10 and the height direction of the column 20, which can reduce the difficulty of installing the bracket 10 and provide greater flexibility for changing the spatial position of the lidar later.

[0034] Specifically, in combination Figure 2 As shown, the bracket 10 is configured with a Z-shaped cross section. The bracket 10 includes a frame 12 and a support plate 11 disposed at the bottom of the frame 12. The surface of the frame 12 is provided with a plurality of first waist-shaped holes 13 extending along its length direction.

[0035] The plurality of second waist-shaped holes 23 are preferably distributed in the upper half of the column 22.

[0036] When fixing the bracket 10, use bolts to pass through the screw holes on the support plate 11 to fix the support plate 11 to the bracket 101. The two brackets 10 should be kept in the same length direction as much as possible.

[0037] Specifically, the column 20 includes a column body 22 and a fixing plate 21 located at the bottom of the column body 22. The fixing plate 21 is fixedly connected to the frame 12 by a first bolt 24. The second waist-shaped hole 23 is distributed along the length of the column body 22. The crossbar 30 is fixed to the column body 22 by a second bolt 31.

[0038] Rubber pads 14 are provided between the fixing plate 21 and the frame 12, and rubber pads 14 are provided between the crossbar 30 and the column 22.

[0039] Thus, the rubber pads can provide cushioning and avoid rigid connections between structural components. That is, the rigid path from the top of the original generator set 100 - bracket 10 - column 20 - crossbar 30 - support platform 40 - mounting platform 50 - lidar can be reduced by adding cushioning pads between bracket 10 and column 20 and between column 20 and crossbar 30, thereby reducing the impact of vibration on lidar.

[0040] In a preferred embodiment, the bracket 10, the column 20, and the crossbar 30 are made of aluminum alloy.

[0041] Combination Figure 1As shown, the cross-section of the crossbar 30 is L-shaped, and multiple triangular reinforcing ribs are provided along its length. This ensures the structural strength of the crossbar 30, providing reliable support for the lidar, and also provides load redundancy for the future expansion of other equipment on the mounting platform 50.

[0042] Combination Figure 1 and Figure 2 As shown, the support platform 40 is provided with three through holes. The height adjustment component includes a threaded rod 51 and a nut 52. The first end of the threaded rod 51 is hinged to the lower end face of the mounting platform 50, the second end of the threaded rod 51 passes through the through hole, and the nut 52 is connected to the threaded rod 51 and presses the support platform 40.

[0043] Thus, when the position of the control nut 52 on the threaded rod 51 is controlled, the spatial angle between the support platform 40 and the mounting platform 50 can be controlled, especially to keep the lidar in a horizontal position.

[0044] Optionally, the mounting platform 50 is provided with multiple mounting holes 53, some of which are used to mount the lidar, while the remaining mounting holes 53 can be used to mount other structures.

[0045] In the above embodiments, the support platform 40 and the crossbar 30 are welded or bolted together to ensure the connection strength and reliability of the structure.

[0046] In conjunction with the above embodiments, the mounting bracket proposed by this utility model constitutes a support structure consisting of a pair of brackets, a pair of uprights, and a crossbar. The uprights can be adjusted in a wide range along the length of the brackets, and the crossbar can be adjusted in height on the uprights. This allows the lidar to be adjusted in a wide range of two degrees of freedom relative to the top of the generator set, providing high flexibility and a large adjustable space. This reduces the difficulty of determining the position during installation and facilitates future expansion and installation of more detection components.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
