Principle of operation

And after the underwater collapse prevention supporting platform is installed and fixed underwater, the pipeline is installed on the platform. Normally, when self-cleaning assembly 83 of the underwater anti-collapse support platform is impacted by water flow, water flow impact impeller 25 drives rolling shaft sleeve 28 to rotate together, water flow on the stressed side enters from water inlet 26 and is discharged from water outlet pipe 27, and the water flow discharged from water outlet pipe 27 washes away silt on the upper edge of movable assembly 82, so that the function of movable assembly 82 is prevented from being affected.

When the underwater anti-collapse support platform is subjected to a strong ocean current or earthquake, water flow impacts the pressure plate 86 on one side, so that the pressure plate 86 compresses the pressure spring 16 inwards in the pressure receiving groove 17, compressed air in the side is pressed into the air guide channel 19 and the compressed air pipe 87 on the side not impacted by the water flow through the air passage 14, the compressed air pushes the pressure piston 20 to push the arc-shaped pressure plate 15 to the support legs 81, and the impact force of the water is counteracted by the thrust generated by the water flow.

Meanwhile, the underwater collapse prevention supporting platform can swing in multiple directions, the buffer block 23 can move in the buffer groove 22 at the moment to reduce impact caused by water flow, when the underwater collapse prevention supporting platform swings up and down, the supporting plate 11 presses down in the movable assembly shell 10, the restoring force of the supporting spring 12 influences reciprocating motion in the movable assembly shell 10, and pressure influence is reduced.
