Embodiment 1

[0042] In the exploratory experiment process of the change of lake sediment properties, there is a problem of lack of real environmental simulation of lake waves in the heterotopic sediment cultivation device in the laboratory. Atmospheric reoxygenation is an important mechanism for supplementing oxygen to the entire lake water body. The wind and wave disturbance of the lake will effectively accelerate the process of atmospheric reoxygenation, which has a great impact on the properties of the lake sediment. If it is used in this kind of heterotopic sediment cultivation experimental device without wind wave disturbance device, the authenticity of the experimental results will be reduced to some extent. In addition, in-situ sediment sampling is carried out in the field to directly measure the properties of the sediment, but it cannot control the uncertain factors in the external environment in the laboratory, resulting in deviations in experimental data. This experimental device...

Abstract

The invention discloses an experimental device and an experimental method for simulating the wave disturbance of a lake, belonging to the field of water environment experiment. In order to solve the problem that the experimental device in the prior art has the disadvantages of non-uniform environment, complex assembly and complicated operation, the invention provides an experimental device and an experimental method for simulating the wave disturbance of a lake. The experimental device comprises an experimental table base. The periphery of the experimental table base is equipped with a support. The support is arranged around and above the experimental table base. A sample culture pool is arranged on the experimental table base. A disturbance device is arranged on the support, and passes through the support into the sample culture pool. Motors rotate circularly to make support rods do up-down linear periodic motion. Under the action of frequency modulators on the motors, the motors rotate at the same speed, and the left and right support rods do different linear motion. By converting mechanical energy into potential energy, the irregular three-dimensional wave of a lake can be simulated. A realistic simulation environment is achieved. The device is simple, and easy to operate.

Description

technical field [0001] The invention relates to the field of water environment experiments, and more specifically relates to an experimental device and an experimental method for simulating lake wave disturbance. Background technique [0002] Ocean surface waves are waves that travel along the interface between water and air, and the restoring force is provided by gravity, so they are often called surface gravity waves. Waves in deep water generally have a constant wavelength. When a wave interacts with the ocean floor, it begins to "shallow". Typically, this occurs when the depth becomes shallower than half the wave's wavelength, the wavelength becomes shorter and the wave amplitude increases. As wave amplitude increases, waves can become unstable because their crests move faster than their troughs. When the wave amplitude is about 80% of the water depth, the wave starts to "break" and we surf. This rising and breaking process depends on the dip and profile of the beach...
