Problems solved by technology

However, the current external measurement methods are difficult to obtain the hydrodynamic force on the sediment particles and the force between the collisions.
Although image-based technology can obtain the trajectory of sediment movement, the accuracy is poor due to the liquid environment and the interaction between particles.

Abstract

The invention discloses a sediment particle three-dimensional simulation motion monitoring experiment device which comprises a water tank for generating water flow, a stocker for storing a plurality of simulation sediment particles is arranged at the water tank, and after a discharge port of the stocker is opened, the simulation sediment particles are released into water. The simulated sediment particles are provided with sensor devices for acquiring three-axis direction stress and motion trail data of the simulated sediment particles, and the simulated sediment particles are also provided with wireless devices for sending data to a computer terminal. The tail end of the water tank is further provided with a measuring device for measuring the transport rate of the simulated sediment particles, and the measuring device is in signal connection with a computer terminal. The device can accurately simulate the entrainment and collision of sediment particles in water flow and analyze the motion trail process. Meanwhile, the simulated sediment particles are collected at the tail end of the water tank, the real-time sediment transport rate of the simulated sediment particles is measured, and new insights and understanding are provided for the water flow sediment carrying motion mechanism.

Description

technical field [0001] The invention relates to the technical field of an experimental device for simulating sediment movement, in particular to an experimental device and method for monitoring a three-dimensional simulation movement of sediment particles. Background technique [0002] In nature, sediment is migrated by the action of water flow, causing erosion and deposition, breaking the original balance of form, and causing damage to surrounding buildings. One of the key issues in sediment research is the mechanism of the sediment transport process. The sediment is carried by the water flow and begins to transport. During the movement, the particles collide with each other and energy transfer occurs. In this process The acquisition of force parameters is indispensable for the study of sediment movement mechanism. At the same time, the acquisition of sediment particle trajectory data will help the study of sediment development and provide new insights into the process of s...
