Description

Technical Field

[0001] The present invention relates to a multi-redundant offshore floating lidar anemometer device. Background Art

[0002] Compared with traditional anemometer towers, floating lidar anemometer devices have technical advantages such as adapting to different water depth environments, lower engineering costs, shorter construction times, and reusability. The most basic requirement for a floating lidar anemometer device is the stable and reliable operation of three core sensor units, namely, a lidar, a high-precision orientation sensor, and a high-precision motion sensor module. This means that the three core sensor units need to function properly and the autonomous power supply unit needs to supply power stably. In addition, a safety protection unit and a data communication unit assist the floating lidar anemometer device to operate continuously and stably. However, existing floating lidar anemometer devices have a high failure rate, and the main failure problems are as follows: lidar failures result in the inability to obtain wind resource data; measurement antenna failures lead to the failure of the high-precision orientation function; system power supply problems cause the system to stop; and system water ingress damages the electrical system. To solve the above failures, on-site operation and maintenance are required, which is time-consuming, laborious, and costly. Offshore operations are highly dependent on sea conditions, so one failure means the loss of wind resource data, affecting the wind resource for at least a few days and at most a few weeks. As long as there are several failures, the entire anemometer measurement activity will not meet the target anemometer requirements. Summary of the Invention

[0003] The present invention relates to a multi-redundant offshore floating lidar anemometer device for solving the above problems.

[0004] To achieve this purpose, the structure adopted by the present invention is: a multi-redundant offshore floating lidar anemometer device, including a floating body and a floating drum.

[0028] Preferably, the solar panel 3 is mounted on the floating body 2 through an adjustable bracket, and the adjustable bracket adjusts the angle between the solar panel 3 and the top surface of the floating body 2.

[0029] The solar panel, wind turbine generator and fuel cell are connected to the battery pack through a power generation controller to provide renewable energy. The battery pack supplies power to the entire device. The fuel cell can be used as a backup power source to ensure that the entire device can still operate under conditions of no wind and no light. The solar panel can be dynamically adjusted according to the latitude of the deployment area to ensure the highest power generation rate. The battery packs in each floating body and floating drum work independently of each other to ensure that the failure of any one battery pack will not affect the operation of other battery packs. The sealed cabin outside the battery pack can prevent water leakage from affecting its operation. The counterweight can adjust the water line of the device and maintain the stability of the device's position. Two weather stations are connected to the lidar to collect the wind speed and direction, atmospheric pressure, atmospheric temperature and atmospheric humidity at sea level. One weather station is used as a redundant backup.

[0030] The motion sensor module, orientation sensor module and one weather station are connected to the data acquisition unit for data acquisition. Two motion sensor modules are redundant with each other and are used to determine the current attitude of the lidar to calibrate the horizontal wind speed data collected by the lidar; two positioning and orientation antennas are connected to an orientation sensor module through coaxial cables. The two orientation sensor modules are redundant with each other to determine the orientation of the lidar based on the true north coordinate system and calibrate the wind direction data collected by the lidar; the satellite communication module and the mobile network communication module are connected to the data communication unit through communication cables to provide satellite communication functions and high-speed mobile data communication. The two satellite communication modules are redundant with each other; the fuel cell is connected to the device monitoring unit.

[0031] As Figure 4 shown, the solar panel 3 is replaced with a triangular closed solar cell group. The triangular closed solar cell group includes 3 vertical solar panels 31. The vertical solar panels 31 form a triangular pyramid structure. A connecting block 33 is provided at the center of the upper and lower sides of each vertical solar panel 31. The connecting blocks 33 of adjacent vertical solar panels 31 are connected to each other through a connecting bar 32.

[0032] This triangular closed solar cell group structure has the characteristics of small installation footprint, firm installation and can make full use of sunlight. It is especially suitable for marine carriers with limited space, enabling the solar panel to still work stably and reliably under extreme weather conditions, providing sufficient power for the monitoring system in the carrier and maintaining its normal operation at sea for as long as possible.

[0033] As Figure 5As shown in the figure, the solar panel 3 is replaced by a vertical solar panel group. The vertical solar panel group includes a fixed bottom plate 34 and three solar panel mounting discs 35 arranged above the fixed bottom plate 34. Each solar panel mounting disc 35 is detachably fixed together from top to bottom by four connecting rods 36, and the positions between the solar panel mounting discs 35 are arranged in an inclined and staggered manner. The solar panel mounting disc 35 located at the bottom is installed on the fixed bottom plate 34 at a certain angle as required through a support column 38. Solar panels 37 are installed on both the front and back of each solar panel mounting disc 35 or only on the front.

[0034] The structure of the vertical solar panel group is simple and ingenious, and it can adapt to sea areas with different latitudes. Especially in the morning, evening, and rainy weather, it can convert solar energy in the space where the carrier is located into electric energy as much as possible to provide sufficient power for the monitoring system in the carrier.

It can quickly respond and handle in case of a fatal failure, thus ensuring the continuity and integrity of the wind measurement data, and at the same time also winning sufficient time for the operation and maintenance work. It is a high-reliability offshore floating lidar wind measurement device.
