The invention discloses a square-combination multiple-layered type experimental device for
zebrafish capable of simulating crowd flow. The square-combination multiple-layered type experimental devicecomprises a partitioning plate, a hedging cabin, a light supplementing device, a water drainage
pipe, a support frame, a carbon-
fiber filter, a water purifying box, a base, a
turbine water pump, a square
fish tank, an oscillation generator, a water inlet
pipe, a hemispheric bell and a spring fixer. The square-combination multiple-layered type experimental device disclosed by the invention has thebeneficial effects that a ratio of the length-width size of the square
fish tank to the length-width size of a practical crowded building site is 0.08, so that the design of a model is more reasonableand is more comparative; and the
zebrafish for simulating the crowd flow, raised in the square
fish tank, can realize that group behavior rules of humankind can be reflected more favorably in
simulation of
emergency evacuation, and a
water level can be controlled to about 1cm when the
zebrafish is raised in the square fish tank, and action of fish school is controlled to realize strict dimensional action, superposition is avoided, and meanwhile, an influence of a reflection effect caused by depth of the
water level on observation also can be reduced.
