Description

Technical Field

[0001] The utility model relates to the technical field of floating offshore wind measurement, in particular to an offshore floating system capable of both wind measurement and ocean hydrological measurement. Background Art

[0002] Floating offshore wind measuring devices are usually equipped with a wind laser radar for wind measurement. By emitting pulse waves to high altitudes and receiving the returned pulse waves, the wind direction and wind speed can be measured at high altitudes. The detection height of the wind laser radar can reach 2-3 km. Many floating offshore wind measuring devices are also equipped with ocean hydrological measurement sensors for measuring seawater temperature, salinity, waves, currents and other ocean hydrological parameters. For example, Chinese patent documents CN 212766658U and CN 216468341U disclose a type of self-stabilizing single floating body that can achieve offshore wind measurement and ocean hydrological measurement. However, this type of floating body still has some shortcomings: (1) It adopts a two-layer structure, with the lower layer being a cabin, a working tower being provided on the cabin, a support platform being provided on the top of the working tower, and the wind laser radar being provided on the support platform. On the one hand, the staff need to climb up and down the working tower for daily inspections and maintenance, which is not very convenient. On the other hand, the overall volume of such a working tower structure is huge and not suitable for being split into small structures. It usually needs to be pre-fabricated in the factory and then transported to the offshore site for installation through overall hoisting and other methods, which results in high construction costs. (2) The ocean hydrographic measurement sensor is arranged in the sensor well of the cabin. Although the seawater in the sensor well is connected to the outside seawater, the temperature and flow rate of the environment in the well are somewhat different from the outside seawater environment because the sensor well is a closed structure. This may result in inaccurate temperature, wave and flow measurements. In addition, in traditional floating offshore wind measurement devices, the ocean hydrographic measurement sensor is directly installed on the bottom of the floating body or the bottom of the ship. Since these surfaces are very flat, they are easily covered by marine organisms such as barnacles. The coverage of the sensor will seriously affect its measurement accuracy. Utility Model Content
