Embodiment Construction

[0018] Below in conjunction with the accompanying drawings, the present invention is further explained:

[0019] A front wind speed tube installed in the front of the wind turbine, such as figure 1 It is characterized in that: the front air velocity tube installed in front of the center of the fan is used to accurately measure the wind speed of the incoming wind in front of the fan, so as to improve the power generation efficiency of the fan; the front air velocity tube is an improved typical pitot tube; the pitot tube measures The dynamic pressure and static pressure of the incoming air flow from the front, and the result is the wind speed; the measured wind speed is sent to the fan onboard equipment for processing, and the accurate correct working angle of the fan blade is obtained after processing, which is used to adjust the correct fan blade. Working angle to achieve maximum power generation efficiency.

[0020] like figure 2 As shown, the front air velocity pipe inclu...

Abstract

The invention discloses a front air velocity pipe installed at the front of a wind generator, and relates to the field of wind generators; the front air velocity pipe installed in front of the center of the fan is used to accurately measure the wind speed of the wind coming from the front of the fan and improve the power generation efficiency of the fan ; The front air velocity tube is an improved typical pitot tube; the pitot tube measures the dynamic pressure and static pressure of the incoming air flow in front, and the result is the wind speed; and sends the measured wind speed to the fan onboard equipment for processing, through The precise correct working angle of the fan blade obtained after processing is used to adjust the correct working angle of the fan blade to obtain the maximum power generation efficiency. The invention accurately measures the wind speed of the incoming wind in front of the fan through the front air velocity pipe installed in front of the fan center, and uses the measured wind speed and atmospheric data to obtain the accurate wind speed and the correct working angle of the fan blades through the calculation center, and adjust the fan to obtain the maximum power generation efficiency. , with outstanding substantive features and significant progress.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a front wind speed pipe installed at the front of the wind power generator. Background technique [0002] Wind, photovoltaics and ocean power are the three lowest-cost, never-ending sources of energy in the future. Due to the limitation of the speed and scope of scientific and technological development, and the technical difficulty of utilizing these three energy sources, the application and popularization are still in a state of low efficiency for decades. [0003] In recent years, wind power has been gradually utilized in China, which has accounted for more than half of the global wind energy utilization. Due to the expensive equipment for wind power generation, the price of wind power is still high despite the fact that wind is a free gift of the earth's nature. [0004] In order to improve the power generation efficiency of wind power generation, it is extremely importa...
