Description

Technical Field

[0001] This utility model relates to the field of lidar wind measurement technology, and more specifically, to a roof-mounted lidar mounting bracket. Background Technology

[0002] In the field of lidar wind measurement technology, lidar is a key device for accurately acquiring atmospheric wind field information. The stability of its installation and the rationality of its location directly affect the accuracy and reliability of the wind measurement data. To adapt to the special operating environment of the cabin, roof-mounted installation has become a widely adopted arrangement method in this field because it can provide lidar with a wide monitoring field of view. The dedicated mounting bracket is the core component for realizing this installation method, and it plays an important role in fixing the equipment and ensuring its stable operation.

[0003] However, existing roof-mounted lidar mounting brackets still have certain limitations in practical applications. For example, Chinese utility model publication CN 218441475U provides a wind-measuring lidar bracket, specifically disclosing a support assembly, lidar, and nacelle shell. The support assembly includes a base, a connecting column, three upper support legs, and three lower support legs. The bottom of the base is fixedly mounted on the connecting column. The three upper support legs are evenly welded to the side wall of the connecting column at an inclined angle. Slots are provided at the bottom ends of the three upper support legs, and the three lower support legs are respectively inserted into the slots at the bottom ends of the three upper support legs. The bottom ends of the three lower support legs are all connected to the top of the nacelle shell. Multiple support pads are evenly and fixedly mounted on the top of the base, and the lidar is fixedly mounted on the multiple support pads. This utility model can freely adjust the height of the support assembly supporting the lidar by adjusting the length of the lower support legs within the upper support legs, and can also enhance the stability of the support assembly, making it less prone to shaking on the nacelle shell. Publication CN 220770729 A Chinese utility model discloses an adjustable bracket for a cabin-type wind-measuring lidar, specifically including a lidar, a rotatable fixed block connected to the bottom of the lidar, a support rod fixed to the circumferential surface of the fixed block, a groove at the bottom of the support rod, a sliding rod slidably inserted into the inner cavity of the groove, and a rotatable base at the bottom of the sliding rod with an anti-slip pad. This prior art allows for convenient height adjustment of the bracket, thereby reducing the workload of height adjustment and facilitating user operation. While the above prior art can meet the requirement of height adjustment flexibility, it still lacks flexibility in angle adjustment, making it difficult to fully adapt to the installation requirements of different lidar models and diverse wind-measuring scenarios, thus restricting the full performance of the lidar to some extent.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Example 1

[0024] This embodiment provides a roof-mounted lidar mounting bracket. Figure 1 See the structural diagram of the mounting bracket for the roof-mounted lidar. Figure 1 As shown, the roof-mounted lidar mounting bracket includes a lower support assembly, a crossbeam, a tripod, and a mounting platform.

[0025] As the basic support component of the bracket, the lower end of the lower support assembly is fixed to the top of the nacelle shell by bolts or welding, and the upper end is used to support the crossbeam. In this embodiment, the height of the lower support assembly is adjustable, so the overall height can be flexibly changed according to the lidar model, the space at the top of the nacelle, or the wind measurement requirements. This effectively avoids interference between the lidar and other components of the nacelle, ensures that it obtains a suitable installation height to guarantee the wind measurement field of view, and enhances the adaptability to different installation environments.

[0026] As the direct supporting component of the lidar, the top surface of the mounting platform is connected to the lidar's base via bolts, thereby securing the lidar. See details... Figure 2 As shown.

[0027] The crossbeam is fixed between the upper ends of each lower support component by welding or bolting to form a laterally stable frame and enhance the overall structural rigidity of the support. A movable seat is slidably installed on the crossbeam, which can slide freely along the length of the crossbeam to adjust the lateral position of the tripod and the installation platform.

[0028] Specifically, the lower support assembly is connected to the top of the cabin shell, and the crossbeam is installed between the upper ends of each lower support assembly, forming a stable support frame. This provides a stable installation foundation for the lidar, effectively resists the influence of external forces such as vibration generated during cabin operation, reduces damage to the lidar caused by shaking or displacement, and extends the service life of the equipment.

[0029] The lower end of the tripod is hinged to the movable base, and its upper end is also hinged to the lower end of the mounting platform. The design of the two ends being hinged allows the tripod to rotate around the movable base and the mounting platform at multiple angles, thereby enabling the mounting platform to adjust its attitude such as pitch and tilt. In addition, the triangular structure of the tripod itself has high resistance to deformation, which can reduce the impact of cabin vibration on the equipment.

[0030] Specifically, the lower end of the tripod is hinged to the movable base, and the upper end is hinged to the mounting platform, forming a multi-degree-of-freedom angle adjustment structure. This allows for flexible adjustment of the pitch angle of the mounting platform, enabling the lidar to accurately target the wind measurement area and maintain the optimal wind measurement posture at all times, thereby ensuring the accuracy of the wind measurement data.

[0031] Example 2

[0032] This embodiment further explains the structure of the tripod based on the technical solution provided in Embodiment 1:

[0033] A universal adjustment assembly is provided between the lower end of the tripod and the upper end of the movable base. In a preferred embodiment, the universal adjustment assembly includes a first U-shaped hinge base, a hinge block, a second U-shaped hinge base, and a foot connecting base.

[0034] The base of the first U-shaped hinge seat is connected to the upper end of the movable seat, and the base of the second U-shaped hinge seat is connected to the lower end of the foot connecting base. The two ends of the hinge block are respectively hinged to the U-shaped joints of the first U-shaped hinge seat and the second U-shaped hinge seat. The tripod and the foot connecting base are provided with threaded holes on their adjacent end faces. The tripod and the foot connecting base are fixedly connected by double-ended bolts that are adapted to the threaded holes.

[0035] It should be noted that the components of the aforementioned universal adjustment assembly form a dual-axis rotation structure through nested hinges, which provides the tripod with multi-angle rotation capability, thereby enabling the mounting platform and lidar to achieve more precise positioning.

[0036] Furthermore, a buffer assembly is provided between the base of the first U-shaped hinge seat and the upper end of the movable seat; in some preferred embodiments, the buffer assembly is a shock-absorbing spring or a hydraulic damper; specifically, the buffer assembly, through its own elastic deformation or damping effect, can convert high-frequency, high-intensity vibrations into heat energy or slowly release elastic potential energy, reducing the vibration amplitude transmitted to the lidar, thereby reducing the interference of vibration on the lidar's wind measurement. In addition, this embodiment also provides a rubber shock-absorbing pad at the lower end of the lower support assembly to further improve the vibration reduction effect of the support.

[0037] Example 3

[0038] This embodiment is based on the technical solution provided in any one of embodiments 1 to 2, and a dust removal mechanism is set on the installation platform, as detailed below:

[0039] See Figure 3 As shown, the dust removal mechanism includes a mounting base, an L-shaped connecting frame, a mounting plate, and an air jet component. The two mounting bases are symmetrically arranged on both sides of the mounting platform. The end of the mounting base away from the mounting platform is provided with a third U-shaped hinge seat. The first end of the L-shaped connecting frame is hinged to the U-shaped joint of the third U-shaped hinge seat through a pin, and can then rotate around the pin.

[0040] As the mounting carrier for the jet nozzles, the mounting plate is erected between the second ends of the two L-shaped connecting brackets. The jet nozzles are arranged on the mounting plate, with their jetting direction facing the optical mirror of the lidar. By connecting to an air supply source, they can spray airflow to remove dust from the optical mirror surface. The jet nozzles can employ an array nozzle design to ensure that the dust removal range covers the entire mirror surface; no specific limitations are imposed here.

[0041] Furthermore, the dust removal mechanism also includes a servo motor and a controller. The servo motor is mounted on the mounting base, and its output shaft is fixedly connected to the U-shaped joint shaft of the third U-shaped hinge seat. The servo motor can directly drive the L-shaped connecting frame to rotate around the third U-shaped hinge seat, thereby precisely adjusting the angle of the mounting plate and the jet component. As the control core, the signal output terminal of the controller is connected to the signal input terminal of the servo motor, and can send pulse signals or commands to the servo motor to control the rotation angle and speed of the motor, thereby adjusting the jet direction of the jet component. In one embodiment, when it is necessary to clean the optical mirror of the lidar, the mounting plate is flipped to the front of the lidar by controlling the servo motor to remove dust from the optical mirror. After dust removal, it can be reset to the bottom of the mounting platform to reduce the impact on the lidar wind measurement. Further details are omitted here.

[0042] Specifically, in this embodiment, the dust removal mechanism further includes a dust sensor. The dust sensor is located on one side of the lidar optical mirror and is used to monitor the dust concentration or coverage area on the mirror surface in real time. The signal output terminal of the dust sensor is connected to the signal input terminal of the controller, transmitting the detected dust data to the controller as the basis for initiating dust removal. Specifically, by continuously providing feedback on the mirror surface cleanliness during the dust removal process through the dust sensor, the controller determines whether to stop dust removal or adjust the angle based on the feedback data, forming a closed-loop control that avoids ineffective airflow or excessive dust removal. Through this closed-loop control, dust removal can be automatically initiated without manual intervention.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
