Abstract
The utility model discloses a reflecting type ball shaped inside projection device which pertains to the simulation spherical science research and teaching experiment device field. The base at the lower end of the ball shaped inside projection screen is provided with a projection lens which is fixed on the projector; a ball surface reflecting mirror is arranged at the upper part of the ball shaped inside projection screen cavity which is directly above the projection lens; the ray projected by the ball surface reflecting mirror reflecting projection lens reaches the inner side if the ball shaped inside projection screen to make the projection angle of the projector into about 180 degree and reflect the image to more than 70 percent area of the ball shaped inside projection screen so that the audiences can view in the scope of 360 degree around the screen. In the universe sphere side, displaying the films of the spheres such as planets, secondary planets and the sun can vividly reveal the mystery of the universe to the people. The utility model is applicable for the space scientific center, the astronomical observatory, the earthquake bureau, the space navigation bureau, the school and the museum, which is able to play an important role in the scientific research and teaching field.
Description
Technical field
The utility model belongs to the scientific research and the teaching test device field of simulating celestial body, particularly a kind of reflective spherical inner projection device.
Background technology
The scientific research of existing simulation celestial body and teaching test device have only the planetarium, just there is similar equipment in the space science research centre, equipment is huge, common adult will wonder some knowledge of celestial body aspect, relevant universe with child, only going to the planetarium to buy tickets sees a film, very saw a few isolated words and phrases, want then some difficulty of overall understanding to 20 minutes.Current small-sized teaching test device is also rare.
Summary of the invention
The purpose of this utility model is to provide a kind of reflective spherical inner projection device at the deficiencies in the prior art.It is characterized in that, an opening is set in the lower end of spherical inner projection screen 1; Fixing projection camera lens 2 in the projector on the base 63, projection camera lens 2 inserts the opening inherence of spherical rear projection screen 1 lower end; At spherical reflector 8 of spherical inner projection screen 1 inner chamber upper support, the input socket of video source 4 connects human-computer interaction device 5, and the output of video source 4 connects projector 3 by signal cable.
Described spherical reflector 8 be supported on projection camera lens 2 directly over, the conical projection light outermost edge light that sends of projection camera lens 2 just in time drops on the hemisphere face of spherical reflector 8, and the distance between the light drop point equals the diameter of spherical reflector 8 relatively.
The position of the inboard spherical reflector of placing of described spherical inner projection screen is that image distribution in projector is in the zone of spherical inner projection screen more than 70%.
Described projection camera lens 2 inserts in the opening of spherical inner projection screen 1 lower end, and its junction is a light-shielding structure.
Described projector is digital projector.
Described video source comprises DVD player, VCD player or computer.
Described human-computer interaction device is the human-computer interaction interface of being made up of touch-screen, mouse, keyboard, button.
Described spherical inner projection screen is the two-sided coarse resin material of thermo forming.
The beneficial effects of the utility model are to utilize spherical reflector that the projection angle of projector is become about 180 degree, can make to the spherical inner projection screen spectators center on screen image projection and view and admire the operator can select different images or film by interactive device in the scopes of 360 degree.Also can be chosen in the assigned address display image of screen.
The spheroid profile utmost point of this spherical inner projection device meets the external form of universe celestial body, aspect performance universe celestial body if describe such as: the slice, thin piece of celestial bodies such as planet, satellite, the sun displays with pitching in this, celestial body that work is taken off exactly, the secret to people displaying universe true to nature.
This product can be used in the space science center widely, in astronomical observatory, seismological bureau, places such as NASA, school, museum, by manifestation modes such as animation and images, show contents such as the relevant earth, satellite, planet, earthquake, ocean, atmosphere, the sun, it can also show the user as required and wants all the elements of showing in addition.The widespread use of interior pitching will have been given play to vital role in scientific research and education sector.
Description of drawings
Fig. 1 is the structural representation of reflective spherical inner projection device.
Embodiment
The utility model provides a kind of reflective spherical inner projection device, in the structural representation of reflective spherical inner projection device shown in Figure 1, an opening is set in the lower end of spherical inner projection screen 1; Fixing projection camera lens 2 in the projector on the base 63, projection camera lens 2 inserts in the opening of spherical inner projection screen 1 lower end, and its junction is a light-shielding structure.At spherical reflector 8 of spherical inner projection screen 1 inner chamber upper support, spherical reflector 8 be supported on the projection camera lens 2 directly over, the conical projection light outermost edge light that projection camera lens 2 sends just in time drops on the hemisphere face of spherical reflector 8, and the distance between the light drop point equals the diameter of spherical reflector 8 relatively, utilize the light 7 of spherical reflector 8 reflection projection camera lenses 2 projections the projection angle of projector 3 to be become about 180 degree, reflect the image onto and to make spectators center on screen in the zone more than 70% of spherical inner projection screen in 360 scopes of spending, to view and admire to spherical inner projection screen inboard.Above-mentioned spherical inner projection screen is the two-sided coarse resin material of thermo forming, prevents that extraneous light from producing hot spot on screen, and the color of projection screen helps producing the image of high-contrast from being seen as ash or black in appearance.The input socket of video source 4 connects human-computer interaction device 5, and the output of video source 4 connects projector 3 by signal cable.The operator can select different images or film by interactive device; Also can be chosen in the assigned address display image of screen.Above-mentioned projector is digital projector; Video source comprises DVD player, VCD player or computer; Human-computer interaction device is the human-computer interaction interface of being made up of touch-screen, mouse, keyboard, button.
The spheroid profile utmost point of this spherical inner projection device meets the external form of universe celestial body, aspect performance universe celestial body if describe such as: the slice, thin piece of celestial bodies such as planet, satellite, the sun displays with pitching in this, celestial body that work is taken off exactly, the secret to people displaying universe true to nature.
This product can be used in the space science center widely, in astronomical observatory, seismological bureau, places such as NASA, school, museum, by manifestation modes such as animation and images, show contents such as the relevant earth, satellite, planet, earthquake, ocean, atmosphere, the sun, it can also show the user as required and wants all the elements of showing in addition.The widespread use of interior pitching will have been given play to vital role in scientific research and education sector.
