supporting plates (19) are arranged at the bottoms of the third side stair strip (11), the second side stair strip (10) and the first side stair strip (9) at equal intervals, and pressure sensors are arranged inside the supporting plates (19);
folding ladder subassembly includes articulated seat in first side (5), folding ladder (4) and second driving motor (6), the one end both sides that first side stair strip (9) were kept away from in support frame storage bin (14) are installed articulated seat in first side (5), the one end mid-mounting of the articulated seat in first side (5) has second driving motor (6), the output of second driving motor (6) runs through the articulated seat in first side (5) and installs the linkage bull stick, and folding ladder (4) are installed in the outside of this linkage bull stick.
10. The method for adjusting a multi-angle rotatable marine extension ladder with pressure sensing function as claimed in claim 8, wherein: the method comprises the following steps:
step 1: a first driving motor (3) is started to drive a first driving gear (2) to rotate, and the position of a large gear disc (7) is adjusted through the first driving gear (2) to drive the extension ladder assembly to rotate 360 degrees to a proper position;
step 2: starting a second driving motor (6) to drive the folding ladder (4) to be unfolded, and then climbing the rescue workers to the top of the support frame storage bin (14) through the folding ladder (4);
and step 3: after the rescuers reach the top of the support frame storage bin (14), the distance between rescuers is judged, then the second screw rod adjusting motor (25) is started to drive the sliding side hinged seat (20) to extend and move, and the first screw rod adjusting motor (18) is started to drive the third side stair strip (11) and the second side stair strip (10) to extend to the position close to the rescuers needing to be rescued;
and 4, step 4: rescuers rescue through the supporting plate (19) in the past and judge the weight through a pressure sensor arranged in the supporting plate (19) so as to judge that several rescuers can rescue at the same time;
and 5: when the person needing to be rescued is conveyed to other higher ship bodies, the angle adjusting driving motor (21) can be started to drive the second driving gear (22) to adjust the reduction gear (23), so that the orientation of the adjusting gear (24) can be adjusted to ensure that the extension ladder assembly can extend towards the higher ship body;
step 6: then the second screw rod adjusting motor (25) is started to drive the sliding side hinged seat (20) to extend and move, and the first screw rod adjusting motor (18) is started to drive the third side stair strip (11) and the second side stair strip (10) to extend to the upper portion of the ship body and then can be lapped above the ship body.
