Technical Field

[0001] The present invention relates to the technical field of offshore wind energy resource observation and evaluation, and particularly relates to an offshore wind energy resource detection device. Background Art

[0002] Offshore wind energy, as a renewable clean energy, has the advantages of large reserves and wide distribution. In the technology of offshore wind power development, wind measurement in a wind farm is the main way to collect data for wind energy resource assessment. The accuracy of wind energy resource data is crucial for the reliability of the test results of the project investment economic benefits and is of great importance to the entire project.

[0003] Currently, the mainly used floating lidar wind measurement equipment in the industry can mainly detect the wind speed and wind direction data distributed at different heights, but cannot obtain the temperature and humidity data at the corresponding heights, resulting in inaccurate calculation of wind power density. The wind energy resource assessment detection system proposed by the present invention mainly includes a microwave radiometer component and a lidar component. Among them, the microwave radiometer component can obtain the temperature profile and humidity profile distributed at different heights, so as to obtain the corresponding air density profile, and the lidar component can obtain the wind speed and wind direction profiles distributed at different heights. The two jointly detect the wind temperature and humidity profiles, which can effectively improve the accuracy of wind power density and is applied to the field of wind energy resource assessment in wind farms.

[0004] Considering that in the actual detection process, the detection system is fixedly arranged on the buoy, and the radar needs observation holes for transmitting and receiving signals. However, the dirt on the surface of the observation holes will interfere with the signals and needs to be cleaned in time. At the same time, a lot of heat is generated during the operation of the detection system, and the heat will affect the normal operation of the radar component and also needs to exchange heat with the outside. The existing detection system uses electricity as the power source and uses two sets of power sources to clean the dirt and exchange heat with the outside respectively, resulting in large power consumption and short overall operation time of the detection system.

[0063] In the specific implementation process, the assembly and debugging are first carried out on land, and then the device is put into the corresponding water area by a ship after the debugging is completed. During the implementation of the detection process, the system control and management unit controls the offshore wind energy resource detection device. Before and during the emission of signals by the microwave radiation component 2 and the lidar component 3, the power component 18 provides power.

When the height of the telescopic column 26 changes, it will drive the lifting plate 27 to lift and lower, and then the lifting plate 27 drives the inclined plate 28 to move. The first rack 29 connected to the inclined plate 28 meshes with the first gear 39, so as to adjust the positions of the collar 37 and the connecting column 6. At the same time, the first rack 29 drives the block 43 to move in the card slot 32.

[0064] The offshore wind energy resource detection device provided by this application realizes the movement of two sets of structures driven by one power source, achieving the purpose of simultaneous pressure reduction, heat exchange and dirt cleaning, saving power and electricity, and prolonging the overall working time of the device. Through the integrated design innovation of the detection system including two sets of components, namely the microwave radiation component 2 and the lidar component 3, the present invention can effectively prolong the overall working time of the device.

[0065] The offshore wind energy resource detection device provided by this application is capable of simultaneously receiving Beidou and GPS navigation signals, supporting independent positioning and combined positioning of Beidou and GPS. The received signals are processed by the data acquisition and system control and management unit to obtain temperature profiles, humidity profiles and air density profiles with different height distributions. At the same time, the lidar component 3 measures the wind speed and wind direction profile elements.

[0066] As an alternative implementation, the telescopic column 26 can also be a hydraulic cylinder or a pneumatic cylinder.

[0067] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
