Problems solved by technology

[0003] Because there are no special experimental facilities, the traditional ice floe experiments can only be carried out by using some simple tools and borrowing existing experimental channels, and manually pouring ice floe into the water flow.
This method is not only inefficient, but also inaccurate
Because various experiments need to be carried out repeatedly, a large amount of repetitive labor not only makes people tired and reduces the accuracy, but also makes the experimental work slow and affects the progress of the experiment.
Especially when conducting an emergency experiment, due to the inability to obtain accurate data on time in an emergency, the best processing time is delayed, causing losses to people's lives and property

Description

technical field [0001] The invention relates to an ice-water coupling comprehensive simulation platform and method, which is an experimental system for simulating the flow state of ice and water, and an experimental system and method for integrating hydraulic engineering, automatic control, and electromechanical integration. Background technique [0002] Before and after the freezing season, a large amount of floating ice will be produced in rivers and canals. The movement and accumulation of floating ice in the river channel will narrow the channel, and even accumulate into ice plugs, forming a dangerous situation of ice jams. Therefore, it is necessary to study the occurrence and evolution of ice plugs, the movement of ice cubes under the ice sheet and other hot issues of river ice hydraulics. For inverted siphons in water channels, ice floes also have various effects. In order to prevent and eliminate the impact of ice floes on inverted siphons, it is necessary to obtain...
