[0069] Example one

[0070] Such as Figure 1-Figure 3 (b) As shown, figure 2 It is a schematic structural diagram of an anti-icing and deicing unit provided by an embodiment of the present invention; FIG. 3(a) is a schematic structural diagram of a floating adsorption contact provided by an embodiment of the present invention Figure one Figure 3 (b) is a schematic diagram of the structure of a floating adsorption contact provided by an embodiment of the present invention Figure II The embodiment of the present invention provides an anti-icing and deicing system for fan blades, including an icing detection unit 10, a control unit 20, and an anti-icing and deicing unit 30, the icing detection unit 10 and the anti-icing and deicing The unit 30 is electrically connected to the control unit 20, wherein:

[0071] The icing detection unit 10 is used to detect the icing condition of the fan blades, and send the detection data to the control unit 20;

[0072] The control unit 20 is config...

Example Embodiment

[0080] Example two

[0081] In the embodiment of the present invention, the anti-icing and deicing unit 30 further includes a plurality of sliding rails arranged in the fan blades, and the axial traveling mechanism 31 moves along the sliding rails.

[0082] By presetting multiple sliding rails in the fan blades, the axial walking mechanism 31 can reach any position of the fan blades along different sliding rails to meet the requirements of anti-icing or deicing at different positions in the fan blades, thus flexibility It is higher, and under the support of the sliding rail, the anti-icing and deicing unit 30 has higher structural stability and longer service life; it should be noted that the multiple sliding rails are all arranged along the length direction of the fan blade.

[0083] Further, the floating adsorption contact 321 is also provided with a vibration monitoring sensor 3213, a temperature sensor 3214, and a limit switch 3215, wherein:

[0084] The vibration monitoring senso...

Abstract

The invention relates to an anti-icing and deicing system used for a wind driven generator set. The anti-icing and deicing system used for the wind driven generator set comprises a freezing detectingunit, a controlling unit and an anti-icing and deicing unit, wherein the anti-icing and deicing unit is arranged at the roots of fan blades; the anti-icing and deicing unit comprises an axial walkingmechanism capable of moving in the length direction of the fan blades and a longitudinal telescoping mechanism arranged at the end part of the axial walking mechanism; the longitudinal telescoping mechanism comprises a manipulator; and a float type adsorbing contact is mounted at the front end of the manipulator, and a vibrator and a far infrared heater are arranged on the float type adsorbing contact. The invention further comprises an anti-icing and deicing method used for the wind driven generator set. According to the system, the anti-icing and deicing unit is arranged at the roots of thefan blades, accordingly the anti-icing and deicing unit moves from the roots of the blades to the anti-icing and deicing position when the anti-icing and deicing are needed and the anti-icing and deicing unit returns to the roots of the fan blades when not needed, so that the problem of the anti-icing and deicing of a fan can be solved, the weight of the fan blades is not increased, and the service life of equipment can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to an anti-icing and deicing system for a wind power generating set and a method thereof. Background technique [0002] In recent years, wind energy has been widely used as a clean energy source, and one of the effective utilization methods is wind power generation. Wind power generation is a power generation method that converts the kinetic energy of the wind into electrical energy. The device required for wind power generation is called a wind turbine (hereinafter referred to as a fan). The fan generally includes three parts: a wind wheel, a generator and a tower. The wind wheel Contains blades, hubs, reinforcements and other components. The working environment of the fan is outdoors where wind resources are relatively abundant. When the air temperature is low or in rainy and snowy weather, ice may form on the blades. Icing the blades of the fan will ch...
