Zero-setting device and zero-setting method for anemoscope of large semi-direct-drive unit

Abstract

The invention discloses a zero-setting device and a zero-setting method for an anemoscope of a large semi-direct-drive unit. The zero-setting device comprises an anemoscope main body clamping mechanism, an anemoscope counter weight limit mechanism and anemoscope laser pen limit mechanisms, wherein the anemoscope main body clamping mechanism comprises a base body, a clamping plate, and matched screw rods and nuts, a V-shaped notch is formed in the front end of the base body, the screw rods are vertically installed at the front end of the base body, and located at the two sides of the V-shaped notch, and the clamping plate sleeves the screw rods; the anemoscope counter weight limit mechanism is vertically installed at the rear end of the base body of the anemoscope main body clamping mechanism, and a V-shaped intersection structure is formed in the top of the anemoscope counter weight limit mechanism, and used for placing a counter weight part of the anemoscope; and the anemoscope laserpen limit mechanisms are installed at the two sides of the base body of the anemoscope main body clamping mechanism separately, and used for accurately locating a laser pen of the anemoscope. The zero-setting device disclosed by the invention is simple in structure, flexible to operate, and capable of being flexibly used according to the field condition, and guaranteeing that a fan unit can be accurately aligned with a windward direction, thereby improving the performance of the unit and increasing the economic benefits of the unit.

Description

technical field [0001] The invention relates to the technical field of installing and zeroing an anemometer of a wind power generating set, in particular to a zeroing device and a zeroing method for an anemometer of a large semi-direct drive unit. Background technique [0002] At present, the anemometers of wind turbines are manually zeroed during installation and operation and maintenance, such as Image 6 As shown, the zero scale line of the wind vane is calibrated parallel to the axis of the hub by virtue of the experience of the technicians. It is difficult to make an accurate judgment on whether the zero scale line of the wind vane is parallel to the central axis of the nacelle due to the human senses. If it cannot be aligned with the direction of incoming wind accurately, the inaccurate zero alignment will cause the overall power curve of the generating set to shift to the right, directly affecting the generating capacity of the generating set, such as Figure 7 shown....

[0002] At present, the anemometers of wind turbines are manually zeroed during installation and operation and maintenance, such as Figure 6 As shown, the zero scale line of the wind vane is calibrated parallel to the axis of the hub by virtue of the experience of the technicians. It is difficult to make an accurate judgment on whether the zero scale line of the wind vane is parallel to the central axis of the nacelle due to the human senses. If it cannot be aligned with the direction of incoming wind accurately, the inaccurate zero alignment will cause the overall power curve of the generating set to shift to the right, directly affecting the generating capacity of the generating set, such as Figure 7 shown
