Embodiment 1

[0034] Please also refer to Figure 1 to Figure 5 , the harbor basin simulation device provided in Embodiment 1 of the present invention will now be described. The harbor basin simulation device includes a harbor basin 1 for simulating a real port channel, a coast or an estuary, a control center (not shown in the drawings), a wave maker 4 for generating waves of different wavelengths and wave heights, and a wave generator for simulating high tides. A flow-making device 5 for ebb and flow, a mobile platform 6 slidingly arranged on the harbor basin 1, a sampling device 7 for fixed-point sampling of the sediment in the harbor basin 1, and a sanding device for sanding to simulate the concentration of suspended sediment 8. The photographing device 9 slidably arranged on the mobile platform 6, the water inlet control valve 11 for controlling the flow-making device 5 to realize the rising tide, and the drainage control switch 13 for controlling the flow-making device 5 to realize the...

Embodiment 2

[0042] Please also refer to figure 1 , this embodiment is an improvement based on the first embodiment. The difference between this embodiment and the first embodiment is that the harbor basin simulation device also includes a wave dissipation area 3 for eliminating waves, and the wave dissipation area 3 It is arranged on the other side of the wave machine 4. Specifically, the wave-making machine 4 is arranged between the flow-making device 5 and the wave-dissipating area 3 . With this structure, when the flow-making device 5 simulates the process of rising and falling tides, the wave-making machine 4 generates waves of different wavelengths and wave heights. By setting the wave-dissipating area 3 on one side of the wave-making machine 4, it can effectively reduce the impact on the harbor basin. 1 The climbing of the waves in the non-test area, thereby reducing the wavelength and wave height of the waves, and playing a certain role in buffering and eliminating.

Embodiment 3

[0044] Please also refer to figure 1 and figure 2 , this embodiment is an improvement based on the first embodiment. The difference between this embodiment and the first embodiment is that guide rails 2 are provided on both sides of the harbor basin 1, and one end of the mobile platform 6 is slidably arranged on a guide rail. 2, and the other end slides on the other guide rail 2. With this structure, the mobile platform 6 is horizontally arranged on the harbor basin 1, and can slide left and right on the harbor basin 1 through the guide rail 2, and then the sampling device 7, the sand filling device 8 and the photographing device arranged on the mobile platform 6 can be adjusted. 9, the sampling device 7, the Gaza device 8 and the photographing device 9 can slide on the mobile platform 6 respectively. Through double movement, the sampling device 7, the Gaza device 8 and the photographing device 9 can be moved to any position on the harbor basin 1. Mobile, easy to realize fi...

Abstract

The invention is applicable to the technical field of harbor port channels and coastal projects, and provides a harbor basin simulation device and a testing method thereof. The harbor basin simulationdevice comprises a harbor basin, a control center, a wave maker, a current making device, a mobile platform, a sampling device, a sand adding device, a shooting device, a water inlet control valve and a drainage control switch. According to the harbor basin simulation device and the testing method thereof, through the current making device, the change situation of rising and falling tide and flowspeed of water current within a set time can be achieved; through the movement of the sampling deice on the mobile platform, sampling of sand at any position in the harbor basin can be achieved; through the movement of the sand adding device on the mobile platform, sand adding at any position of the harbor basin can be achieved; through the movement of the shooting device on the mobile platform,any position of the harbor basin can be shot and monitored, and thus waves, tides and other physical parameters and the evolution situation of tidalflat landform features can be monitored in pixel time sequences. Testing data measured by means of the testing method is precise and usable.

Description

technical field [0001] The invention belongs to the technical field of port waterway and coastal engineering, and in particular relates to a harbor basin simulation device and a test method thereof. Background technique [0002] In port channels and coastal engineering, coastal and estuary wave tide sediment simulation experiments, the wave-making and flow-making device is a necessary experimental device for physical model research. The concept of the physical model is based on the mechanical laws of water flow and sediment movement. Similarity theory, making a solid model geometrically similar to the prototype, based on the dynamic and dynamic similarity as the criterion, experimentally researching the water flow, wave, sediment movement and river bed evolution law (including the corresponding changes before and after the project) of rivers, lakes, estuaries, and coasts The process is called physical simulation, and the similar model made and tested on is called physical mo...
