Embodiment Construction

[0018] The present invention will be further described in detail below in combination with specific embodiments.

[0019] Such as figure 1 As shown, the present invention is an experimental device for simulating the anti-anchor damage of submarine pipelines. It includes an anchor frame 1, and the anchor frame 1 is slidably connected to the top surface of the model groove 6 through a guide rail slider structure. 1 is fixed with a crossbeam 3, and a row of threaded holes are arranged on the crossbeam 3, and a threaded hole in the selected falling direction is internally threaded with a lead screw 4 arranged in the vertical direction. The lower end is fixed with an electromagnetic switch, and when the electromagnetic switch is turned on, the experimental anchor 2 is adsorbed, and an inverted trapezoidal rockfill protective layer 9 formed by filling gravel is arranged in the middle of the lower part of the model tank 6. The model grooves 6 on the left and right sides of the rockf...

Abstract

The invention discloses an experiment device for simulating seabed pipeline anchor damage prevention. The experiment device comprises an anchor dropping frame. The anchor dropping frame is connected to the top face of a model slot in a sliding mode through a guide rail sliding block structure. A beam is fixedly arranged on the anchor dropping frame. A lead screw is connected to the beam. An electromagnetic switch is fixedly arranged at the lower end of the lead screw. When the electromagnetic switch is turned on, an experiment anchor is attached, and an inverted trapezoidal gravel filling protective layer formed by gravel filling is arranged in the middle of the lower portion inside the model slot. Sea sand is laid inside the portion, on the left side and the right side of the gravel filling protective layer, of the model slot. The portion, above the top face of the sea sand, of the model slot is made of toughened glass. A submarine pipeline is embedded inside the gravel filling protective layer. A resistance-type strain gauge sensor is arranged on the wall of the seabed pipeline. The resistance-type strain gauge sensor is connected with a data collection system through a wire. A supporting plate is installed on the inner wall of the end, opposite to the anchor dropping frame, of the model slot, and a servo motor dragging system is installed at the end, opposite to the anchor dropping frame, of the model slot. The experiment device can simulate the continuous anchor dropping and anchor dragging process.

Description

technical field [0001] The invention relates to an experimental device for simulating a submarine pipeline, in particular to an experimental device for simulating the anti-anchoring damage of a submarine pipeline. Background technique [0002] With the continuous development of offshore oil and gas transportation, submarine pipelines have been widely used. In the area crossing the channel, the risks faced by the pipeline mainly come from the anchoring operation of passing ships. Once the submarine pipeline is damaged or leaked, it will cause incalculable economic losses, and the damage to the marine environment is even more unimaginable. In the previous design of crossing waterways, rockfill protection or deep burial methods were usually used to ensure the safety of the pipeline. increase in engineering costs. Therefore, the design of rockfill protective structures poses a relatively difficult challenge. [0003] Bruce Company uses translucent synthetic laponite to simul...
