Automation device for simulating tidal movement

Abstract

The invention discloses an automation device for simulating tidal movement. The automation device comprises a control system, a fresh water filling system and a salinity stabilizing system, wherein the fresh water injecting system and the salinity stabilizing system are controlled by the control system and connected with each other; the salinity stabilizing system comprises a tail pool, a first salt pool and a second salt pool, wherein the tail pool, the first salt pool and the second salt pool are separated from each other; the tail pool is divided into a shallow water part and a deep water part which is connected with the first salt pool and the second salt pool; the fresh water filling system comprises a fresh water pool, a variable frequency pump and a water tank; the variable frequency pump and the water tank are placed into the fresh water pool; and one end of the water tank is connected with the fresh water pool, while the other end of the water tank is connected with the shallow water part of the tail pool. The automation device disclosed by the invention has the characteristics of simple structure, flexibility in assembling and good stability; the automation device for simulating tidal movement not only can simulate to receive the fresh water from the upstream, but also can ensure the stable salinity at the bottom of a gate of a river mouth at the same time. The automation device adopts the variable frequency pump in the present market, and therefore, the flow of single pump can be adjusted without limitation, and the device can be operated flexibly.

Description

technical field [0001] The invention relates to the technical field of tidal simulation models, in particular to an automatic device for simulating tidal movement. Background technique [0002] The estuary is the confluence of the ocean and the river. The salinity at the bottom of the estuary is affected by the ocean, and the salinity is stable; while the upper reaches of the estuary receive fresh water from runoff, and the salinity is close to zero. Therefore, the interior of the estuary is affected by upstream runoff and downstream tides, and the water level, flow field and salinity field will change over time. [0003] At present, some estuary and coastal engineering research or basic research tasks require not only to reproduce the tide and current phenomena in the physical model, that is, to accurately simulate the tide level process and water flow process; but also to accurately simulate the distribution of salinity. Especially in some studies, the salinity distributi...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the shortcoming of the current tidal simulation model is that it cannot not only accept the upstream fresh water, but also ensure the stability of the salinity at the bottom of the estuary.
