Square-combination multiple-layered type experimental device for zebrafish capable of simulating crowd flow

Abstract

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.

Problems solved by technology

[0002] With the rapid development of urbanization, large-scale crowd flow and evacuation have become major issues and research hotspots in public security and emergency management. Theoretical modeling of crowd evacuation is difficult, and the reliability of numerical simulation is uncertain. Experiments have always been an important research method, including Organize real crowd drill experiments and animal simulation experiments, and the square combined multi-layer experimental device for zebrafish simulated crowd flow is designed based on this technology, providing a simulated animal experiment method that is more in line with the behavior of human groups , in order to reduce the action characteristics of crowds that do not conform to it, and significantly affect the evacuation results

[0003] As far as the experimental devices for simulating crowd flow on the market are concerned, there are more or less problems. First, there are large differences in the reaction and action mechanisms of the selected simulated experimental animals and human beings. When simulating experiments, the experimental structures obtained often have large errors. Second, the simulated devices constructed are not designed according to a certain ratio with the actual dense building sites of human beings, so there is no similarity criterion established based on the characteristic size analysis , which makes the design of the model unreasonable and lacks comparability. Third, for the existing simulation experimental device using small terrestrial animals such as mice, ants and other simulated populations for experiments, there will be cascading problems, that is, the simulated animals cannot be strictly controlled.
