Detailed implementation manner

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] As Figures 1-4 shown, an intelligent ballast trimming and righting system includes ballast tanks for adjusting the transverse and longitudinal of the platform, chamber liquid level sensors and platform draft sensors. Chamber liquid level sensors and platform draft sensors are provided in the ballast tanks. The platform draft sensors are electrically connected to the intelligent load adjustment control module 19. The platform draft sensors are connected to the draft filtering device 17. The draft filtering device 17 is electrically connected to the intelligent load adjustment control module 19 through the automatic device for solving transverse and longitudinal inclination 18. The automatic device for solving transverse and longitudinal inclination 18 transmits the transverse and longitudinal inclination angles and the average draft to the intelligent load adjustment control module 19. The intelligent load adjustment control module 19 controls the ballast pumps to be electrically connected to the ballast tanks. When the floating wind turbine encounters bad sea conditions, it can automatically calculate based on the data of the liquid level sensors and draft sensors through the intelligent load adjustment control module 19, control the liquid level of the ballast tanks, and sequentially adjust the platform to the best state, improve the stability of the platform, and reduce the risk of platform capsizing.

[0027] There are three ballast tanks, namely the starboard ballast tank 1, the port ballast tank 2 and the fore ballast tank 3. Each ballast tank is correspondingly provided with a left draft sensor 4 and a #1 liquid level sensor 7, and a bow draft sensor 5 and a #2 liquid level sensor 8, and a right draft sensor 6 and a #3 liquid level sensor 9. The #1 liquid level sensor 7, the #2 liquid level sensor 8 and the #3 liquid level sensor 9 are respectively electrically connected to the intelligent load adjustment control module 19 through the data transmission line 10 for liquid level sensors.

[0028] The left draft sensor 4 and the right draft sensor 6 are located as far as possible on both sides and are symmetric. The bow draft sensor 5 and the #2 liquid level sensor 8 are on the median line between the left draft sensor 4 and the right draft sensor 6.

[0029] The draft filtering device 17 filters the real-time draft curve transmitted by the draft sensors to obtain the average draft at each position.

[0030] The transverse and longitudinal inclination automatic solution device 18 automatically calculates the transverse inclination, longitudinal inclination and average draft of the platform based on the draft data transmitted by the draft filtering wave device 17, and transmits the data to the intelligent load adjustment control module 19.

[0031] The intelligent load adjustment control module 19 incorporates an intelligent reduced-order model. This model immediately calculates the required ballast water for each ballast tank after the platform is righted based on the data obtained by the transverse and longitudinal inclination automatic solution device and the real-time data provided by the cabin liquid level sensors, and controls the ballast pump to transfer water. The intelligent load adjustment control module 19 automatically calculates the liquid level of the ballast tank after the platform is righted, and controls the ballast pump and the automatic valve to automatically right the platform, thereby improving the power generation efficiency of the fan.

[0032] The ballast pump includes a main ballast pump 14 and a standby ballast pump 15, which are in standby with each other. The ballast pumps are connected to the ballast tanks respectively through the ballast pipelines 11. The tops of the ballast pumps are respectively connected to the check valves 22 and connected to the sea chest 16 through the automatic valves 13. By using the check valves 22 on the ballast pumps, the phenomenon of liquid diversion in the ballast pumps can be prevented.

[0033] The check valve 22 is connected to the ballast pipeline 11 of the ballast pump through the ballast pipeline 11. Automatic valves 13 are provided on each of the ballast pipelines 11. The automatic valves 13 are connected to the sea chest 16 and the intelligent load adjustment control module 19 through pipelines. By adjusting the opening and closing of the automatic valves 13 for load adjustment, the ballast water in the ballast tanks can be transferred to each other, or the ballast water can be pumped into the ship from outside the ship, or the ballast water can be pumped out of the ship from inside the ship.

[0034] The intelligent load adjustment control module 19 is simultaneously connected to the local display 20 and the cloud storage 21. The local display 20 real-time displays the average draft and the liquid level data of each ballast tank calculated by the intelligent load adjustment control module 19. The cloud storage 21 real-time receives the average draft and the liquid level data of each ballast tank calculated by the intelligent load adjustment control module 19 and uploads them to the cloud, which can real-time display the current draft and the liquid level conditions of each ballast tank. At the same time, it is equipped with a cloud storage system 21, which can transfer the result data of each calculation to the cloud for later data accumulation and training.

[0035] When the floating wind turbine encounters severe sea conditions, after the draft sensor measures the triangular draft of the platform, it is transmitted to the draft filtering device 17 through the draft sensor data transmission line. The triangular draft of the platform is transmitted to the transverse and longitudinal inclination automatic solving device 18 through the draft filtering device 17. The transverse inclination, longitudinal inclination and average draft obtained by solving this device are transmitted to the intelligent load adjustment control module 19 through the data line. The #1 liquid level sensor 7, #2 liquid level sensor 8 and #3 liquid level sensor 9 measure the liquid levels of each ballast tank, and transmit the liquid levels of each ballast tank to the intelligent load adjustment control module 19 in real time through the liquid level sensor data transmission line 10. The intelligent adjustment module automatically solves the final draft and the liquid levels of each ballast tank based on the existing transverse and longitudinal inclination data, average draft, and the liquid level data of each ballast tank, and adjusts the liquid levels of each ballast tank by controlling the ballast pump 14, standby ballast pump 15, and automatic valves to straighten the platform, thereby improving the power generation efficiency of the wind turbine and enhancing the anti-overturning ability of the wind turbine.
