SU105624A1 - Training device to simulate the movement of a star in the field of view of an astronomical instrument tube - Google Patents

Description

The subject of the invention is a training device for imitating the movement of light, 1a in the field of view of an astronomical and tomb tube, equipped with a simulating light source and screen.

The use of a training device allows to imitate imitation of all possible conditions of the motion of a star.

The peculiarity of the device is that the light source is set by a screened and unresponsive carriage driven by an electric motor, driven by a screw, mounted on a rotatable platform, driven in the form of a worm gear and a gear wheel from a hand wheel.

The device used a round translucent screen with a paired net of threads and a comb, imggirovushchu field of view of astronomical tools.

FIG. 1 shows a similar view of a training device; in fig. 2 - view of the turntable: in FIG. 3shema drive platform; in fig. 4- carriage type; in fig. 5 - electrical circuit of the device.

On the hinged lid / housing 2

the training device is mounted a translucent screen 3 with a grid of threads applied to it / and a comb 5, imitating the field of view of an astronomical instrument.

Behind the screen 3 in the housing 2 there is a turntable platform 6. which is driven from the handle of the handwheel 7 through a system of gears and worm gears 6, 9, W and // (see Fig. 3); The front side // is rigidly connected to the platform 6 and rotates around its axis to the right and left from 0 to 80. The rotation of the platform sets the angle of inclination of the light movement along the daily parallel relative to the horizon line, i.e. the movement of the light index relative to the horizontal threads 4 of the screen grid 3.

On the platform there is mounted a slant, a carriage 75 along the lead screw / 2, carriage 75, layers, and a light source imitating a star. The light source is an electrolamp 14, the light from which passes through a pinhole in a brass cartridge 75 mounted on a carriage so that it can be moved to various distances from the screen, thus achieving a change in the size of the light 105624
