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 experimental device for simulating the anti-anchoring damage of submarine pipelines. There is a lead screw, and an electromagnetic switch is fixed at the lower end of the lead screw. When the electromagnetic switch is turned on, an experimental anchor is adsorbed. An inverted trapezoidal rockfill protection layer formed by filling gravel is arranged in the middle of the lower part of the model tank. Sea sand is laid in the model tanks on the left and right sides of the layer, and the material of the model tanks above the top of the sea sand is made of tempered glass. Submarine pipelines are embedded in the rockfill protective layer, and resistive resistors are installed on the tube walls of the submarine pipelines. The strain gauge sensor, the resistive strain gauge sensor is connected to the data acquisition system through wires, a support plate is installed on the inner wall of the model groove at the end opposite to the anchor frame and a servo motor dragging system is installed on the model groove at this end. The device can simulate the continuous process of dropping anchor and dragging anchor.

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...
