Problems solved by technology
The wave current flume is a hydraulic experiment tool for studying two-dimensional hydrodynamics. When the moving bed experiment of the beach section is carried out in the wave current flume, due to the limitation of the scale, the wave current flume can only do the dynamic bed change inside the section, and cannot Realize the simulation of sand transport along the coast from this section to adjacent sections

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0023] see Figure 1-Figure 6 , Schematic diagram of the structure and working principle of an erosional beach littoral sand transport simulation device for a wave current flume.
[0024] The schematic diagram of the structure of the erosive beach sand transport simulation device used in the wave current flume is shown in figure 1 As shown, the coastal sand transport simulation device is mainly composed of three parts: three sand dredgers, three conveyor belts and a wave baffle.
[0025] The first sand dredge 1, the second sand dredge 2, and the third sand dredge 3 have adjustable speeds and are arranged on one side of the water tank along the axial direction of the water tank. The first sand dredger 1, the second sand dredge 2, and the sand dredger bucket of the third sand dredge 3 are connected to the crawler belt 8, and a filter screen 10 ...

The invention relates to a corrosive beach coastal sand conveying simulating device used for a wave flow flume, and the corrosive beach coastal sand conveying simulating device is used in the wave flow flume. The corrosive beach coastal sand conveying simulating device used for the wave flow flume comprises a first sand excavating device, a second sand excavating device and a third sand excavating device, wherein the first sand excavating device, the second sand excavating device and the third sand excavating device are arranged to the side inside the wave flow flume along the axial direction of the flume. A first conveyor belt, a second conveyor belt and a third conveyor belt are respectively arranged in the model sand dumping positions of the first sand excavating device, the second sand excavating device and the third sand excavating device. One ends of the first conveyor belt, the second conveyor belt and the third conveyor belt are respectively located below the model sand dumping positions of the first sand excavating device, the second sand excavating device and the third sand excavating device, and the other ends of the first conveyor belt, the second conveyor belt and the third conveyor belt are connected with the outside of the flume. Wave baffle plates are arranged between a main body of the wave flow flume and the first sand excavating device, the second sand excavating device as well as the third sand excavating device to reduce disturbance of water flow and waves caused by the first sand excavating device, the second sand excavating device and the third sand excavating device. When a moving bed flume wave flow experiment is carried out, the corrosive beach coastal sand conveying simulating device can overcome the defect that the wave flow flume can only solve two-dimension problems to some extent, can simulate conveying out of corrosive beach coastal sand conveying, and can simulate different coastal sand conveying with different sand conveying amount on the upper, middle and lower portions of a profile.
Description
technical field [0001] The invention relates to a simulation device for transporting sand along the coast of an erosive beach used in a wave current tank, which can realize the simulation of transporting sand along the coast of an erosive beach in a moving bed experiment of a wave current tank. Background technique [0002] The moving bed experiment refers to the experiment in which the bottom of the bed evolves under the action of waves and water currents. The wave current flume is a hydraulic experiment tool for studying two-dimensional hydrodynamics. When the moving bed experiment of the beach section is carried out in the wave current flume, due to the limitation of the scale, the wave current flume can only do the dynamic bed change inside the section, and cannot Realize the simulation of sand transport along the coast from this section to adjacent sections. Contents of the invention [0003] The purpose of the present invention is to overcome the limitations of the ...
