Problems solved by technology

Therefore, the tsunami wave formed by the gate opening method is quite different from the actual tsunami wave, and lacks the guiding significance for actual engineering
[0005] In addition, the deep-sea gravity flow simulation generation device and the tsunami simulation generation device have a high similarity in model boxes, water supply, and generation devices, and there is a possibility of integration and sharing
The hydraulic cylinder is placed at the bottom of the liquid storage tank to pull the gate horizontally, so that after the gate is opened, the liquid at the bottom of the liquid storage tank cannot participate in the tsunami simulation, resulting in the waste of some liquid and making it impossible to store liquid The simulation of gravity flow at the bottom of the tank does not have the function of deep sea gravity flow simulation

Abstract

The invention discloses a device for simulating a tsunami / gravity flow under a super-gravity field. According to the device, a gate quick lifting unit, a model box and a liquid storage tank are combined to simulate the generation of a tsunami and deep sea gravity flow under a super-gravity environment. According to the device, tsunami and gravity flow simulation is unobstructed, smoother and quicker; all liquid in the liquid storage tank of the device can participate in tsunami simulation; the liquid storage tank of the device can provide space for the storage and stirring of mud when realizing the simulated occurrence of the tsunami, and therefore, the simulation of the deep sea gravity flow is realized, and the function and use scope of the device can be expanded; a stirring unit is mainly used to a seabed gravity flow simulation experiment; before the seabed gravity flow simulation experiment is started, the mud in the liquid storage tank is continuously stirred through the stirringunit, and therefore, the uniformity of the mud can be ensured, the precipitation or agglomeration of the mud can be avoided; and thus, the device of the invention can better simulate the gravity flow.
