Description

Technical Field

[0001] The utility model relates to the technical field of wind measurement lidar brackets, and more specifically, to an adjustable bracket for a wind measurement lidar. Background Art

[0002] A lidar is a radar system that detects the position, speed and other characteristic quantities of a target by emitting laser beams. Its working principle is to emit a detection signal to the target, and then compare the received signal reflected from the target with the emitted signal. After appropriate processing, relevant information about the target can be obtained.

[0003] A lidar bracket is a structural component used to fix and support a lidar device. It plays a crucial role in the application of lidar. The design of a lidar bracket usually needs to consider various factors, such as stability, accuracy, adjustability, and adaptability to the environment, etc. Stability ensures that the lidar does not shake or displace during operation, thus guaranteeing the accuracy of measurement data. Accuracy is related to whether the bracket can accurately position the lidar at the required position and angle.

[0004] Chinese Patent with the authorization announcement number CN218441475U discloses a wind measurement lidar bracket. This structure can freely adjust the height of the support component for supporting the lidar by adjusting the length of the lower support leg inside the upper support leg, and can also strengthen the stability of the support component, making it not easy to shake on the cabin shell.

[0005] However, when this structure is actually used, it is more troublesome to repeatedly pull out and insert bolts to adjust the height, which reduces the user experience and practicality. Moreover, it is difficult for the lidar to detect different orientations, and the detection range is low. Summary of the Utility Model

[0006] In order to overcome the above defects of the prior art, the utility model provides a wind measurement lidar bracket to solve the problems raised in the above background art.

[0007] To achieve the above object, the utility model provides the following technical solution: A wind measurement lidar bracket, including a bottom plate, a plurality of fixing blocks are arranged on the surface of the bottom plate, a connecting column is arranged on the top of the bottom plate, and a plurality of support components are arranged between the bottom plate and the connecting column and are connected by the plurality of support components;

[0008] The support assembly includes upper support legs which are welded to the outer wall of the connection column in an inclined shape. A plurality of fixing grooves are evenly formed on the surface of the upper support legs. A sliding groove is arranged on one side of the fixing groove. An upper sliding groove is formed inside the upper support legs. A telescopic spring is fixedly connected inside the upper sliding groove. A lower support leg is slidably connected inside the upper sliding groove. A lower sliding groove is formed at the top of the lower support leg. A clamping rod is fixedly connected to the surface of the lower support leg. A lidar is arranged at the top of the connection column. A rotating mechanism is arranged between the connection column and the lidar and they are connected through the rotating mechanism.

[0009] In order to achieve the purpose that the lidar can detect different angular orientations, preferably, the rotating mechanism includes a chassis which is fixedly connected to the top of the connection column. A bearing is fixedly connected to the top of the chassis. A collar is fixedly connected to the outside of the bearing. The collar is rotatably connected to the chassis through the bearing. A plurality of connecting columns are fixedly connected to the top of the collar.

[0010] In order to ensure that the fixed angle of the device is not affected by the external environment, preferably, a tray is arranged at the top of the chassis. The lidar is installed on the surface of the tray. A plurality of fixing holes are arranged on the surface of the tray. Fixing pins are arranged in the fixing holes. The tray is connected to the collar through the connecting columns. The chassis is provided with a limiting mechanism.

[0011] In order to enhance the stability of the device, preferably, the limiting mechanism includes a plurality of stabilizing holes arranged on the surface of the chassis. The fixing pin passes through the fixing hole and extends into the stabilizing hole.

[0012] In order to achieve the effect of stabilizing the support assembly, preferably, the bottom end of the lower support leg is movably connected to a fixing block, and the fixing block is installed on the surface of the bottom plate through bolts.

[0013] In order to achieve the effect that the clamping rod can freely slide in the fixing groove and the sliding groove, preferably, the fixing groove and the sliding groove are communicated. The clamping rod is slidably installed inside the sliding groove, and the clamping rod is adapted to the structure of the fixing groove.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. By setting the support assembly, compared with the prior art, when the height of the bracket needs to be adjusted, by rotating the lower support leg, the clamping rod can be driven to transfer from the fixing groove into the sliding groove, and then the clamping rod can be slid in the sliding groove. When the adjustment reaches the appropriate height, the lower support leg can be rotated to make the clamping rod transfer into the fixing groove, and then the limit fixation of the support assembly can be completed. Then, the fixing block at the bottom of the lower support leg is fixed on the surface of the bottom plate through bolts. Through the above operations, the height of the support frame can be adjusted efficiently, thereby reducing the workload of adjusting the height of the bracket and improving the user experience.

[0016] 2. By setting up a rotating mechanism, compared with the prior art, the collar can rotate relative to the chassis through a bearing. When in use, the lidar tray and the collar rotate together, while the chassis and the support assembly are not affected, achieving the purpose of detecting the lidar in different directions.

[0017] 3. By setting up a limiting mechanism, compared with the prior art, when the angle is adjusted, the fixing pin passes through the fixing hole and the stabilizing hole, which can prevent the chassis and the tray from rotating relative to each other, thereby fixing the position of the lidar, and ensuring the accuracy and stability of the lidar.
