Since the projection image light emitted by the projector 9 needs to be imaged on a scattering medium, the scattering medium generating device 10 is necessary. The scattering medium generating device 10 may be, for example, a device for manufacturing a water curtain which can eject a water curtain of a certain size, and the projected image light emitted from the projector 9 is irradiated on the water curtain to display an image. The scattering medium generating device 10 may be, for example, a device for producing water mist, and the projected image light emitted from the projector 9 may be irradiated on the water mist to display an image. The scattering medium generating device 10 can also be, for example, a projection screen machine, which can release a projection screen for projection display by the projector 9 during operation.
Moreover, the projector 9 can change the type or action of the image of the natural enemy of the birds constantly, the birds can see the dynamic image of the natural enemy of the birds, and the image of the natural enemy of the birds can be changed for a certain time, so that the bird repelling effect is further enhanced.
In some embodiments, as shown in fig. 8, the scattering medium generating device 10 includes:
and the water sprayer 101 is arranged on the cross arm shielding sheet 3 and used for spraying a water curtain to the projection direction of the projector, and the water curtain is used for scattering image light emitted by the projector so as to display images of natural enemies of birds.
This embodiment adopts the mode of water curtain projection, can set up water sprayer 101 at the side of cross arm shielding piece 3, and water sprayer 101 upwards sprays water and forms the water curtain, and the projecting apparatus setting is in the top of cross arm shielding piece 3, and the water curtain that sprays to water sprayer 101 shines the projection image light, and the projection image light shows birds natural enemy image on the water curtain to realize the water curtain projection.
In some embodiments, the water sprayer 101 is disposed outside the air outlet range of the air nozzle, so as to prevent the air output by the air nozzle from blowing the water curtain sprayed by the water sprayer 101, and the blown water curtain cannot well display the projected image emitted by the projector.
In some embodiments, as shown in fig. 9, the sprinkler 101 includes: a water storage tank 1011, a water outlet pipe 1012, a water pump 1013, an atomizing nozzle 1014 and a rectifying nozzle 1015; water storage tank 1011 is used for storing water; the water outlet pipe 1012 is connected with the water storage tank 1011 and is used for guiding water; a water pump 1013 is installed in the outlet pipe 1012 for pressurizing water in the outlet pipe 1012; the atomizing nozzle 1014 is assembled on the water outlet of the water outlet pipe 1012 and is used for converting the water output by the water outlet pipe 1012 into water mist and outputting the water mist; and a rectifying nozzle 1015 is assembled on the atomizing nozzle 1014, and is used for limiting the water mist sprayed out by the atomizing nozzle 1014 to be in the projection direction of the projector, and rectifying the water mist sprayed out by the atomizing nozzle 1014 into a fan shape.
In this embodiment, the water pump 1013 extracts and pressurizes water from the water storage tank 1011, the pressurized water flows to the atomizing nozzles 1014 through the water outlet pipe 1012, the water outlet pipe 1012 may include a plurality of water outlets, the water outlet pipe 1012 divides the water and outputs the water from each water outlet, each water outlet is connected with one atomizing nozzle 1014, and the atomizing nozzles 1014 form a row on the cross arm shielding sheet 3. The atomizing nozzle 1014 atomizes the water flow and then sprays the water flow in a fog shape, and when the water flow is sprayed out, the rectifying nozzle 1015 shapes the water fog to enable the sprayed water fog to be fan-shaped. As shown in fig. 9, the fairing nozzle 1015 may adopt a flat duckbill pipe, the water inlet of the duckbill pipe may be a circular opening, and the water outlet of the duckbill pipe is made into a flat rectangular channel, so as to shape the water mist into a fan shape. The rectifying nozzle 1015 can shape the water mist and limit the spraying direction of the water mist, so that the water mist is sprayed in the projection direction of the projector. The fan-shaped water mist sprayed by the plurality of rectifying nozzles 1015 forms a water mist surface, and the image light projected by the projector presents the image of natural enemies of birds on the water mist surface, so that the effect of frightening the birds is achieved.
In some embodiments, the cross-arm shelter is further configured to: the corners are set to be round corners for protecting installation workers. The corners of the cross-arm masking blade may be rounded by pre-fabrication to prevent workers from being injured when removing and installing the cross-arm masking blade.
