The middle shaft needs to load the shafting structure closest to the load and the weight of the external load, and the outermost shaft needs to load the shafting structures of the middle shaft and the two shafts closest to the load and the weight of the external load. This results in large loads and high cost and difficulty for high precision three-axis rocking platforms.

Referring to fig. 9 and 10, fig. 9 is a schematic structural view of an inclined structural member according to an embodiment of the present disclosure, and fig. 10 is a schematic structural view of an assembly rotating mechanism according to an embodiment of the present disclosure.

More specifically, for the inclined structural member 301 (e.g., the first inclined structural member 311 and the second inclined structural member 321), which has a first mounting portion 3011 and a second mounting portion 3012, taking the second mounting portion 3012 in a horizontal plane as an example, the first mounting portion 3011 is inclined relative to the second mounting portion 3012, and at this time, the inclination angle of the inclined structural member 301 is the inclination angle of the first mounting portion 3011 relative to the second mounting portion 3012; the first mounting portion 3011 is used to connect to the component rotating mechanism 302 of another rotating unit upwards, and the second mounting portion 3012 is used to connect to the component rotating mechanism 302 of the present rotating unit downwards.

It should be explained that the floating wind lidar is a marine floating wind measurement system which carries a coherent doppler wind lidar on a buoy, is matched with a high-precision real-time attitude measurement system, and carries out real-time correction on a floating body along with the swing of sea waves. Whether the swing can be corrected in real time at sea or not is the key of the wind measuring precision of the system, and how the correction algorithm is. A coherent Doppler wind lidar is a remote sensing type laser wind measuring device which uses pulse laser to measure the movement speed of tiny particles in the atmosphere. The measurement height of small devices is typically several hundred meters. During measurement, the device is generally required to be stably fixed, and accurate leveling and positioning are carried out to ensure the measurement accuracy.

For example, when the inclination angle a is 8 degrees, the maximum roll inclination angle of the system is 16 degrees, and most of the marine roll environment can be covered.

It should be noted that the inclination angle can also be adjusted as needed to accommodate similar applications, in which the simulated inclination angle of the buoy is mainly centered within 15 degrees for periods of about 5-20 seconds, with different directions of oscillation, and with slowly varying course over a wide range.

In this embodiment, in conjunction with fig. 4 and 5, it will be appreciated that the figures show two discs with 8 degree tilt with a bearing arrangement between them to allow relative rotation. When the two inclination directions are completely opposite, the inclination is equivalent to offset, and the top surface is in a horizontal state, as shown in fig. 6; when the inclination directions are the same, the inclination angles are completely superposed, and the top surface is at an inclination angle of 16 degrees, as shown in fig. 7 and 8. By controlling the relative positions of rotation of the two disks, the angle of inclination of the top surface to within any 16 degrees can be controlled.

In addition, the swing platform uses a firm and durable rotary worm speed reduction bearing structure with strong loading capacity, is driven by a closed-loop servo motor, can accurately control the rotating speed and the position of the upper rotary speed reducer and the lower rotary speed reducer so as to realize the characteristics of accurately controlling the swing angle, direction, period and the like, and the top rotary speed reducer is mainly used for controlling the course of the loading platform.

In some embodiments, the inclined structure 301 and the assembly rotating mechanism 302 are both hollow structures, that is, each inclined structure 301 and each rotating speed reducer are hollow structures, and a conductive slip ring is accommodated in the middle, so that power and control signals can be sent to the position of the load platform 1 step by step without being affected by continuous rotation of each intermediate step. And can also provide a path for power and control signals to the load of the load platform 1.

In some embodiments, the load platform 1 is provided with lightening holes, and the centre of symmetry of the load platform 1 is located on the rotation axis of the swivel assembly 3 when the load platform 1 is not tilted.

In the embodiment, various rotary speed reducers are mature common mechanical bearing structures, have high load capacity on axial force, radial force and overturning force, have stable and reliable performance, have IP66 in self protection property, and can be used in outdoor environment for a long time. The worm speed reducer is arranged in the rotary speed reducer, the reduction ratio is adjustable, the matching precision is high, and the torque requirement on the driving motor is greatly reduced. And the weight of the load is not placed on the driving source (motor) but supported by the bearing structure, and the supporting structure is not influenced when the motor is powered off. The motor does work only for changing the load posture, is economical and efficient, and is suitable for long-time operation.

It should be noted that many of the components mentioned in this application are either common standard components or components known to those skilled in the art, and their structure and principle are known to those skilled in the art through technical manuals or through routine experimentation.

It should be noted that in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The high reliability rocking stage provided by the present application is described in detail above. The principles and embodiments of the present application are explained herein using specific examples, which are provided only to help understand the method and the core idea of the present application.
