Embodiment Construction

[0017] Such as Figure 1 to Figure 4 As shown, the opening of the U-shaped pipe 8 is set vertically upwards, and its right end is open and communicated with the atmosphere. A pressure sensor 9 is arranged at an appropriate height. A control valve 3 is arranged between the U-shaped pipes 8, and a seabed model installation section 20 is arranged in the middle of the bottom section of the U-shaped pipe 8. The seabed model 14 is installed in the installation section 20, and a laser is arranged above the seabed model installation section 20. Sheet light source 7, one side of seabed model installation section 20 is provided with a video camera 16 (see image 3 ).

[0018] The housing 18 of the control valve 3 is made integrally with the U-shaped pipe 8, and a valve plate 6 is installed in its inner chamber through the rotating shaft 4, and a stepping servo motor 17 is provided on the outer surface of one side of the housing of the control valve 3 (see Figure 4 ), the output shaft...

Abstract

The invention discloses a modeling device that is made up of a control device, and a U shaped tube. One end of the U shaped tube connects to air and the other connects to winding machine by pipe. A control valve is set on the pipe that the winding machine connects to U shaped pipe. A seabed modeling installation section is set on the bottom section of the U shaped tube, where the seabed model is installed. The winding machine and the control valve electrically connect to the control device. The invention supplies theory basis for researching to the transferring situation of shoaling sea area.

Description

technical field [0001] The invention relates to a device for simulating the condition of seabed sand transport under the action of ocean currents. Background technique [0002] With the continuous development of marine mining resources, the development of cross-sea communication, and the construction of offshore engineering facilities, people are laying more and more pipelines on the seabed. Because these pipelines have been in extremely harsh working environments for a long time, in addition to bearing the high pressure of seawater, the seabed where they are located is always scoured and eroded by tidal currents and wave currents. Once the seabed around the pipeline is emptied, the If the pipeline is suspended, it is easy to cause the pipeline to break. Therefore, in order to ensure the safety of the pipeline, it is better to have a sufficient buried depth for the pipeline. Since the laying of these pipelines is carried out at the deep bottom, with the increase of the bur...
