Embodiment
By the following examples and accompanying drawing the present invention is described in further detail:
The invention provides and a kind ofly there is protection type and the laser bird dispeller of comprehensive scan control can be realized, as shown in Figure 1, comprise laser instrument 1, beam expander 2, protective cover 3, dimensional turntable 4 and electric box 5.
The laser center wavelength that described laser instrument 1 sends is 532nm, beam diameter is 2mm, power is 1W, and frequency and pulsewidth are all adjustable.Show according to the research of birds to each spectrum sensitive degree, wavelength is that the green glow of 532nm is the most responsive to birds, and birds can be made to produce the feared state of mind.Small bird is subject to the stimulation of BG laser beam, reacts and flies away from protected field, thus reach the object of driving bird for seeking survival.
Described beam expander 2 light path is as shown in Figure 2, incident successively for sequence has negative lens 2-1, balsaming lens 2-2, condenser lens 2-3, speculum one 2-4, speculum two 2-5 and collimation diaphotoscope 2-6 successively with laser.Its effect is the diameter sent by described laser instrument 1 is the green laser beam of 2mm, and expanding diameter is 150mm.So not only be conducive to reaching better effect on driving birds, harm can not be produced to the people and animals of direct irradiation simultaneously.In addition, adopt two pieces of speculums by light path folding, not only reach and required expand multiplying power, also substantially reduce the length of beam expander.
Described dimensional turntable 4 all has null pick-up at trunnion axis and pitch axis, and at pitch axis, mechanical position limitation is installed, possesses the setting of arbitrary scan speed within the scope of arbitrary scan region within the scope of level 360 ° of continuous rotations, pitching ± 90 ° and 0.1 °/s ~ 120 °/s, and can according to driving bird requirement, under described dimensional turntable control module 5-4 controls, realize location, fan sweeping, cruise sweep, presetting bit and comprehensive scan control.Adopt this dimensional turntable with comprehensive scan control, the green laser beam after expanding, collimating is made to strafe airfield runway and peripheral region thereof according to path planning continuously, thus create a permanent deathtrap, affect the ecotope that birds depend on for existence, perch and look for food, Stimulation of Birds finds habitat that is new, safety.It is more intelligent that the bird scope of driving and making that described dimensional turntable 4 not only expands laser bird dispeller drives bird, and also more convenient to the selection of whole bird-scaring unit installation site.
The diameter of described protective cover 3 is 500mm, has waterproof and dustproof effect, can effectively prevent the adverse circumstances such as heavy rain, freezing, sandstorm to the interference of laser bird dispeller, simultaneously also for laser instrument 1, beam expander 2 provide a relatively clean dustless space.Under the Temperature and Humidity Control module 5-2 effect of described electric box 5 inside, automatically the temperature and humidity of cover inside can be regulated, described protective cover 3 inside is made to have a metastable working environment, prevent the performance of laser bird dispeller to be subject to the impact of external temperature and humidity, reduce the fault rate of laser bird dispeller.
The described inner principle of electric box 5 as shown in Figure 3, power supply module 5-3 transfers the civil power (alternating current 220V) of input to low-voltage dc power supply needed for each parts, works for described dimensional turntable control module 5-4, Laser Modulation module 5-1, Temperature and Humidity Control module 5-2 and laser instrument 1.Laser Modulation module 5-1 can according to the sensitivity of birds to green laser frequency, and producing pulsewidth and frequency all can the laser beam of real-time change, and realize multiple sudden strains of a muscle effect frequently, drive bird targetedly, bird efficiency is driven in raising.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
