Example 2
Fig. 4 shows an offshore floating type wind power generator platform stabilizing device provided with a plurality of wind shielding structures, which comprises a fan impeller 4 and a fan tower 5, wherein the fan tower 5 is arranged on a platform base, the platform base is connected with a platform sleeve 8 and three floating platforms 6 by adopting a platform truss 7, the platform sleeve 8 is arranged at the centers of the three floating platforms 6, the lower end of the fan tower 5 is fixedly connected with the platform sleeve 8 in an insertion manner, the upper end of the fan tower 5 is rotatably connected to the bottom surface 3d of a cabin 3 by a bearing, and the windward end of the cabin 3 is provided with the fan impeller 4. The wind-shielding structure comprises a wind-shielding plate 1 and a telescopic arm 2, a cabin top surface 3a, wind-shielding plate grooves 9 for collecting and releasing the wind-shielding plate 1 are formed in a cabin left side surface 3b and a cabin right side surface 3c, the lower ends of the three wind-shielding plates 1 are respectively hinged with groove edges 3f of windward ends of the wind-shielding plate grooves 9, telescopic arm grooves 2c are formed in the three wind-shielding plate grooves 9, a fixed arm 2a of the telescopic arm 2 in the three telescopic arm grooves 2c is hinged with a fixed structure in the telescopic arm grooves 2c, and a movable arm 2b of the telescopic arm 2 is hinged with the inner surface of the wind-shielding plate 1.
The electric or hydraulic telescopic arm can control the motion state of the telescopic arm 2 according to the motion speed direction of the fan, and further adjust the swing angle of the wind shield 1. Because the same wind shielding structure is additionally arranged on the side part of the fan cabin and operates in the same mode, the anti-rolling effect of the mechanism is increased.
When the telescopic arm does telescopic motion, the telescopic arm drives the wind shield connected with the upper end of the telescopic arm to swing by a shaft at the front end of the cabin shell; the telescopic arm can control the motion state of the telescopic arm according to the motion speed direction of the fan along the direction of the fan under the control of the transmission system, and further adjust the opening and closing of the attack angle of the wind shield; the swing angle of the wind shield can be adjusted according to the swing speed of the cabin and the swing degree of the platform, so that the swing of the platform is reduced.
Fig. 5 shows a hydraulic and control system schematic. The hydraulic mechanism adopts a hydraulic oil pump 13 to provide pressure oil for a pressure stabilizing tank 14, and the telescopic arm 2 is connected with the pressure stabilizing tank 14 through an oil supply electromagnetic valve and is connected with an oil storage tank 15 through an oil return electromagnetic valve. The controller 10 adopts a PLC controller, an air speed sensor 11 arranged outside the engine room 3 and a pressure sensor 11a arranged on a pressure stabilizing tank 14 are electrically connected with the PLC controller, and a control relay of each oil supply electromagnetic valve, each oil return electromagnetic valve and each motor 12 is electrically connected with the PLC controller.
When the pressure sensor 11a detects that the pressure in the surge tank 14 is lower than 0.7MPa, the PLC controller controls the control relay of the motor 12 to be electrified, the motor 12 drives the hydraulic oil pump 13 to work, and when the pressure in the surge tank 14 is higher than 1.0MPa, the PLC controller controls the control relay of the motor 12 to be powered off.
When the wind speed sensor 11 detects that the wind speed is reduced, the wind pressure acting on the wind shield 1 is also reduced, the PLC simultaneously opens the first oil supply electromagnetic valve V1 and the first oil return electromagnetic valve V2, and closes the second oil supply electromagnetic valve V3 and the second oil return electromagnetic valve V4, so that the opening angle of the wind shield 1 is increased, and the wind pressure acting on the wind shield 1 is increased; when the wind speed sensor 11 detects that the wind speed is increased, the wind pressure acting on the wind shield 1 is also increased, the PLC simultaneously opens the second oil supply electromagnetic valve V3 and the second oil return electromagnetic valve V4, and closes the first oil supply electromagnetic valve V1 and the first oil return electromagnetic valve V2, so that the opening angle of the wind shield 1 is reduced, and the wind pressure acting on the wind shield 1 is reduced.
As shown in fig. 3, the point G is a swing center of the whole offshore floating wind turbine platform, and when the platform works on the sea, the whole platform swings around the point G as a circle center due to the action of wind, waves and current on the whole platform; setting the moving speed V of a cabin of the fan and taking the working wind direction of the fan as the positive direction (as shown in the figure); when the speed V of the fan cabin is greater than 0 (equivalent to the increase of the wind pressure on the wind shield 1), the telescopic arm extends, the opening angle of the wind shield 1 is increased, so that the resistance in the-V direction is generated, and the swing of the fan platform is inhibited; when V <0 (equivalent to the reduction of the wind pressure on the wind deflector 1), the telescopic arm contracts, the opening angle of the wind deflector 1 is reduced, and the wind deflector 1 can be retracted to the closing position of the wind deflector groove 9 of the cabin shell to the maximum extent, so that the thrust of the wind deflector 1 in the-V direction is not increased.
The PLC controller is a programmable logic controller of a digital operation electronic system and is used for controlling the production process of machinery. The simplest Siemens S7 series PLC commonly used in the market at present has small volume, high speed and standardization, has network communication capacity, stronger function and higher reliability, an S7-200 PLC controller (the model is 6ES7211-0BA23-0XB0, an AC/DC/relay, 6-point input and 4-point output) is a micro PLC, and is suitable for automatic detection, monitoring and control and the like in various industries and occasions, and the powerful function of the S7-200 PLC enables the PLC to realize complex control functions no matter a single machine operates or a network is connected.
