Sand table device capable of simulating sunlight illumination

The invention belongs to the technical field of sunlight illumination simulation, and particularly relates to a sand table device capable of simulating sunlight illumination. The sand table device comprises a sand table, wherein a sand table intermediate layer and a sand table bottom plate are sequentially arranged in the sand table from top to bottom; sceneries is arranged at the upper part of the sand table intermediate layer; the sand table device is characterized in that a light source track rack is arranged on the sand table; the two ends of the light source track rack are respectively fixed on a rotating shaft of a pitching stepping motor; the pitching stepping motor is connected with a telescopic lead screw of a horizontal movement stepping motor; a plurality of light sources are arranged on the light source track rack. The sand table device disclosed by the invention has the benefits that the light source track rack can be pitched and rotated to simulate sunlight track in different seasons, so that the illumination effect of the sunlight at a certain time in the four seasons on the sceneries in the sand table can be judged, which brings much convenience to study sunlight illumination in certain industries, for example, the device is very favorable to sunlight illumination simulating sand tables used in industries of construction, public security, military and the like; the device is easy to control automatically and popularize.
