Abstract

The invention discloses a blade deicing system coupled with geothermal energy. The blade deicing system comprises a fan tower, blades, a first heat exchange pipe and second heat exchange pipes; the top of the first heat exchange pipe is inserted into the fan tower and located on the top of the fan tower; the bottom of the first heat exchange pipe is located in an underground geothermal energy area; each blade is provided with one second heat exchange pipe; the second heat exchange pipes are arranged in the length direction of the blades; and the ends of the second heat exchange pipes are close to the top of the fan tower. Underground geothermal energy is transferred to the top of the fan tower through the first heat exchange pipe, heat at the top of the fan tower is transferred to the roots of the blades through contact heat conduction, the second heat exchange pipes absorb the heat and transfer the heat to the tail ends of the blades, and therefore, the blades are effectively prevented from being frozen.

Description

technical field [0001] The invention belongs to the field of wind power and relates to a blade deicing system coupled with geothermal energy. Background technique [0002] Wind energy is a widespread renewable energy source, and wind turbine blades are one of the important components of wind power generation. However, wind turbines may be installed in remote mountainous areas, where the humidity is high and the temperature is low, which can easily lead to icing on the blades, which can reduce power generation in the slightest and cause safety accidents in severe cases. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a blade deicing system coupled with geothermal energy, which transmits geothermal energy to the blades and effectively prevents the blades from icing. [0004] In order to achieve the above object, the present invention adopts the following technical solutions...
