In FIG, the elevation angle adjustment mechanism 2 according to the laser for wind power generating set of the embodiment of the present invention, comprising laser bodies 3, be arranged on the emitting head 1 in laser bodies 3 and be connected with emitting head 1.
Because the hot spot diffusion of laser is little, be not subject to ambient light impact, relative to other light beams, adopt laser Emission Lasers bundle to make the visualization of operating process higher and more accurate.
Emitting head 1 is for Emission Lasers bundle, parallel with the projection of wind vane N-S line and overlap by the horizontal projection of setting laser bundle, and this laser beam is used to determine the wind direction the azimythal angle of mark N-S line.
The elevation angle of elevation angle adjustment mechanism 2 adjustable laser, and when adjusting the elevation angle, the laser beam projects that emitting head 1 is launched to different directions is to being projected on same straight line on horizontal plane.Therefore, when determining the wind direction the azimythal angle of mark N-S line, no matter elevation angle size, all can ensure that light beam is on same straight line in horizontal projection and the projection in the horizontal plane of N-S line.
In addition, elevation angle adjustment mechanism is arranged on the top of wind vane, and with fastening lock screw, once the adjustment of the laser elevation angle is complete, can lock immediately, thus the change of the horizontal projection direction of the light beam avoiding laser to launch.Make like this can carry out elevation angle adjustment operation when wind vane is installed for the first time, once need not again adjust after adjusting complete locking.
Adopt fastening locking screw designs, avoiding obstacles or lock laser after adjustment when adjustment laser can be made to be irradiated to the position on ground, thus avoid cause this laser to send because the elevation angle is unreasonable beam projection to obstacle instead of project on ground; Also can meet the blower fan demand of different model, different heights in addition, make can generally be applicable to each type during the azimythal angle of laser for the mark N-S line that determines the wind direction.
This laser has radio communication function, attendant can utilize install in mobile phone or other equipment can the communication software of this laser of switch to generate wireless control signal, and wireless control signal is sent to the receiver (not shown) of laser, carry out trigger laser Emission Lasers bundle or close laser.Thus operation maintenance personnel, when detecting, can detect wind vane at any time as long as press switch, meanwhile, detection can close laser by switch after terminating again.
