Or, the second support arm 6 may be a solid structure, and the lines are disposed outside the second support arm 6, where it should be noted that all lines used are waterproof, and thus the lines do not have any influence after contacting with seawater.
In this embodiment, the wind measuring platform 5 is further provided with an auxiliary leveling mechanism 502 for improving the levelness of the wind measuring platform 5; the wind measuring platform 5 may have various structures, specifically, for example, the wind measuring platform 5 has a regular polygon shape, and the auxiliary leveling mechanism 502 may be disposed at an end point of the wind measuring platform 5.
It should be noted that the auxiliary leveling mechanism 502 includes a hydraulic cylinder, and the leveling of the wind measuring platform is more accurate by controlling the hydraulic cylinder to work to finely adjust the whole wind measuring device. For example, the hydraulic cylinder can adopt a swing type hydraulic cylinder which comprises an actuating element for outputting torque to realize reciprocating motion, wherein the actuating element is divided into a blade type and a spiral swing type, the wind measuring platform is described by taking the spiral swing type as an example, and the double-spiral swing type hydraulic cylinder is a composite motion which is converted into linear motion and autorotation motion by means of linear motion of pistons in the hydraulic cylinder through two spiral pairs, so that swing motion is realized, the inclination of the wind measuring platform is compensated, the levelness requirement of the whole wind measuring platform is ensured, the precision requirement of a radar wind meter is further ensured, and the accuracy of wind measuring data is improved; it should be noted that the auxiliary leveling mechanism 502 is not limited to a hydraulic cylinder, and a motor-driven follow-up leveling assembly or other driving adjustment device may be used.
It should be further noted that, when the horizontal sensor on the supporting platform 4 senses the inclination of the floating dynamic leveling assembly, the horizontal sensor will quickly respond, and the inclination signal is fed back to the driving controller, and the paddle 103 is driven by the driving motor 104 to provide driving force for leveling the self state of the buoyancy tank 1, so as to further adjust the levelness of the supporting platform 4; then the position signal is fed back to a control system of the anemometry platform 5, and the anemometry platform 5 is leveled by controlling a hydraulic cylinder, so that the inclination caused by the displacement difference is quickly compensated; finally, the displacement deviation of the floating dynamic leveling component after leveling can be compensated to meet the requirement of required horizontal precision, and the floating dynamic leveling component has the advantages of convenience in installation and low construction difficulty.
The wind measuring construction process comprises the following steps:
1. before the wind measuring device goes to sea, the assembly of the buoyancy tank 1 and the wind measuring platform 5 can be completed at a port or a wharf which is close to a wind measuring sea area, so that the problem of difficult construction and assembly under sea is solved, and the wind measuring device has the advantages of high construction speed, high installation efficiency and low manufacturing cost;
2. the wind measuring device is hoisted into the sea by using onshore hoisting equipment, the whole wind measuring device floats on the sea surface by virtue of buoyancy provided by the buoyancy tank 1, and meanwhile, the supporting platform 4 does not play a role of providing buoyancy, so that the wind measuring device is conveniently towed to a preset wind measuring sea area by a towing ship, and the resistance in towing can be reduced;
3. after towing to a preset wind measuring sea area, water injection is started in a water containing cabin 401 of a supporting platform 4 through a water injection and drainage port 402 to enable a buoyancy tank 1 to sink, meanwhile, the supporting platform 4 is suspended on the sea surface, then the supporting platform 4 is fixed with the sea bed through an anchor cable 3, the tensioning degree of the anchor cable 3 is adjusted, and the supporting platform 4 is positioned;
4. debugging the radar anemoscope 501 to meet the requirement of the working state;
5. the wind measurement is started, the wind measurement platform 5 is leveled, and the levelness requirement of the wind measurement platform 5 is ensured through the whole leveling system, so that the wind measurement precision requirement of the radar wind meter 501 is met;
6. after the wind measurement is finished, the anchor cable 3 is retracted, water in the cabin 401 containing the supporting platform 4 is discharged out of the cabin, the whole supporting platform 4 floats to the water surface, and the whole wind measuring device is towed to another sea area for wind measurement.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
