Detailed Description
The present invention will now be described in further detail with reference to specific examples, which are intended to be illustrative, but not limiting, of the invention.
As shown in fig. 1-4, the invention discloses a floating offshore wind turbine anti-typhoon structure, which comprises a controller 10, a wind measuring radar 8, an electronic gyroscope 9, a high-pressure air pump 11 and a buoy mechanism; the controller 10, the wind measuring radar 8 and the electronic gyroscope 9 are arranged on the wind turbine generator 1; the float mechanism is arranged below the fan tower drum 2 and comprises three floats 3, and the upper side and the lower side of each float 3 are respectively provided with an electric valve 4; the high-pressure air pump 11 is arranged in the fan tower barrel 2, and the high-pressure air pump 11 is communicated with the interior of each buoy 3 through an air duct 6; the wind measuring radar 8, the electronic gyroscope 9, the electric valve 4 and the high-pressure air pump 11 are all connected with the controller 10.
Preferably, a signal receiving antenna 7 is further installed on the wind turbine generator 1, one end of the signal receiving antenna 7 is connected with the controller 10, and the other end of the signal receiving antenna 7 is wirelessly connected with a remote device.
Specifically, as shown in fig. 3, the wind turbine generator 1 includes a nacelle, a signal receiving antenna 7 is disposed at an upper portion of the nacelle, an electronic gyroscope 9 and a controller 10 are installed inside the nacelle, and a wind measuring radar 8 is installed at a center position of a hub.
As shown in fig. 1, the high pressure air pump 11 is disposed at a position below the center of the tower and flexibly connected to the three air pipes.
As shown in fig. 4, the high pressure air pump 11 is connected with one end of the air duct 6 through a corrugated tube 12, so as to realize flexible connection between the high pressure air pump 11 and the air duct 6. The air duct 6 belongs to a metal piece with a long length, and the expansion caused by heat and the contraction caused by cold become obvious. If the bellows 12 is not used, the stress of the pipeline to the high pressure air pump 11 is abnormally large, and even the pipeline or the air pump structure is damaged.
The electric valve 4 on the lower part of the float 3 is arranged on the central position of the float 3, and the electric valve 4 on the upper part is arranged on the eccentric position of the float 3. The electric valve 4 at the lower part of the buoy 3 is arranged at the central position of the buoy 3 because the lower part of the buoy 3 is always positioned in seawater, the environment is severe, the influence on the structure is reduced as much as possible, and the opening at the central position is considered in the aspect.
In the upper part of the pontoon 3, the valve is mounted eccentrically in the pontoon 3, mainly on the basis of air flow considerations. If the upper valve is also arranged at the central position, the air flow can be vertically upwards and downwards when the fan descends, and the control is difficult. The fan is arranged at an eccentric position, so that air flow can flow out only after certain circulation in the buoy 3 when the fan descends, and the problem that the buoy 3 descends too fast and is difficult to control is solved.
As shown in fig. 2, the three buoys 3 are arranged in a triangle, and the three buoys 3 are fixedly connected through a buoy support 5.
The controller 10 stores an upper limit preset height, a hub height, a wind wave avoiding height, and a lower limit preset height. The height of the hub of the fan is different due to different fans, the height of the hub of the current mainstream fan is generally 100m, the lower limit preset height is generally 3/5 of the height of the hub of the fan, the height of the wind wave sheltering is 1m higher than the lower limit preset height, and the upper limit preset height is 1m higher than the height of the hub.
The wind speed change and the fan attitude are sensed through a wind measuring radar 8 and an electronic gyroscope 9 which are arranged on the wind turbine generator 1, and are analyzed and judged through a controller 10, and meanwhile, the controller 10 can also receive a control instruction from a far end through a signal receiving antenna 7. The controller 10 determines that the height of the fan needs to be raised or lowered according to the analysis judgment or the control instruction, and sends a working instruction to the electric valve 4, the high-pressure air pump 11 and the like.
The method for judging and executing the descending operation of the wind turbine generator 1 comprises the following steps: when the wind measuring radar 8 senses the peripheral wind speed and the wind direction changes greatly, or the electronic gyroscope 9 senses signals that the wind turbine generator 1 shakes seriously and the like comes, or receives an instruction sent by a far end through the signal receiving antenna 7, the controller 10 analyzes and judges or receives the instruction through an internal logic program, and determines that the height of the fan needs to be lowered. The controller 10 issues a valve opening command to all the electrically operated valves 4. With all the electrically operated valves 4 open, seawater enters the buoy 3. The wind turbine generator 1 gradually decreases as the buoyancy of the buoy 3 decreases. When the height of the wind-wave sheltering wind-wave shelter device is close to the lower limit preset height, the controller 10 sends a gradually-closing valve instruction to the electric valve 4, and finally the electric valve 4 is closed, so that the height of the wind turbine generator 1 reaches the lower limit preset height.
The method for judging and executing the ascending operation of the wind turbine generator 1 comprises the following steps: when the wind measuring radar 8 senses the peripheral wind speed and the stable wind direction change, or the electronic gyroscope 9 senses that the wind turbine generator 1 shakes slightly and continues for a period of time, or receives an instruction sent by a far end through the signal receiving antenna 7, the controller 10 analyzes and judges or receives the instruction through an internal logic program, and determines that the height of the fan needs to rise. The controller 10 sends a valve opening instruction to the electric valve 4 positioned at the lower part of the buoy 3, and simultaneously sends a starting instruction to the high-pressure air pump 11 positioned at the high position of the fan tower 2. The high-pressure air pump 11 continuously inputs high-pressure air into the buoy 3 through the air duct 6, and the wind turbine generator 1 gradually floats upwards. When the wheel hub height is reached, the controller 10 sends a gradually-closing valve instruction to the electric valve 4, sends a deceleration instruction to the high-pressure air pump 11, and finally enables the electric valve 4 to be closed, the high-pressure air pump 11 is in standby, and meanwhile, the height of the wind turbine generator 1 reaches the upper limit preset height.
Specifically, when the peripheral wind speed detected by the wind measuring radar 8 exceeds 52.5m/s and the 5min wind direction changes by more than 180 degrees, or when the vertical direction angle deflection value of the wind turbine generator 1 sensed by the electronic gyroscope 9 continuously exceeds 10 degrees for 3 times, the controller 10 judges that the wind turbine generator 1 needs to descend through analysis and judgment;
when the peripheral wind speed detected by the wind measuring radar 8 does not exceed 52.5m/s within 30min and the wind direction change does not exceed 180 degrees, or the electronic gyroscope 9 senses that the angle deflection value of the wind turbine generator 1 in the vertical direction does not exceed 10 degrees, the controller 10 judges that the wind turbine generator 1 needs to ascend through analysis and judgment.
