Problems solved by technology
[0003] Passive deicing requires downtime operation, which affects the normal operation and power generation of the unit, and wastes manpower and material resources
After the wind turbine resumes operation, if the blades are iced again, they need to be shut down, which cannot fundamentally solve the problem; in the method of active deicing, heating and deicing and warm air need to consume a lot of electric energy, which affects the normal operation of the unit. When heated continuously, it affects the aerodynamic performance of the blade; spraying special materials can alleviate the icing to some extent, but the coating will deteriorate over time

Embodiment Construction
[0019] Attached below Figure 1-2 The present invention is further illustrated with specific examples.
[0020] Such as figure 1 As shown, a fan blade intelligent deicing robot includes:
[0021] The vehicle body 4 can be remotely controlled to move the vehicle body 4 and move on the surface of the blade body 1 during deicing;
[0022] The rotating camera 2 installed on the car body 4 is used to photograph the position of the ice on the surface of the blade body 1;
[0023] The deicing executive component installed on the car body 4;
[0024] The control system controls the deicing execution parts to perform the deicing operation according to the position of the ice on the surface of the blade body 1 captured by the rotating camera 2 .
[0025] In this embodiment, the entire deicing robot is light-weight and small in size, and will not affect the normal operation of the blade body 1 during deicing. The vehicle body 4 is provided with a wheel set, and the vehicle body 4 rol...

The invention relates to an intelligent deicing robot for fan blades, and belongs to the field of wind power generation equipment. The intelligent deicing robot comprises a vehicle body, a rotary camera, a deicing execution part and a control system. The vehicle body is movably arranged and moves on the surfaces of blade bodies during deicing; the rotary camera is arranged on the vehicle body andis used for shooting ice block positions on the surfaces of the blade bodies; the deicing execution part mounted on the vehicle body; and the control system controls the deicing execution part to perform deicing operation according to the ice block positions on the surfaces of the blade bodies shot by the rotary camera. The automatic image recognition technology is fully adopted to assist in removing ice on the surfaces of the blade bodies.
Description
technical field [0001] The invention relates to the field of wind power generation equipment, in particular to an intelligent deicing device for blades of a wind power generator. Background technique [0002] At present, in wind power generation, the icing of wind turbine blades has a great impact on the operating equipment and power generation of wind turbines, and even causes the wind turbine blades to break or shut down. In this regard, researchers have proposed a variety of deicing methods, which are mainly divided into passive deicing and active deicing. Passive deicing adopts the method of spraying special materials or black coating on the surface of fan blades to reduce the contact between ice and snow and blades. Active deicing includes electric heating, warm air, and mechanical deicing. Heating and deicing is to add heat-conducting materials inside the fan blades, and use electrical conductor heating to create gaps between the surface of the fan blades and the ice...
