A push rod 9 is arranged inside the sleeve rod 8 through a first electric push rod 9. An adjusting block 10 slides in the groove at the bottom end of the sleeve rod 8. The adjusting block 10 is in a prismatic structure and is connected to the bottom of the push rod 9 through the groove. Rhombic card slots are correspondingly formed on the surfaces of the driving bevel gear 73 and the rotating cylinder 752 for the adjusting block 10. When controlling the rotation of the driving bevel gear 73, the first electric push rod 9 pulls the push rod 9 to move forward inside the sleeve rod 8 towards the front side of the hull 1, so that the adjusting block 10 is engaged into the rhombic card slot formed on the surface of the driving bevel gear 73. When controlling the rotation of the rotating cylinder 752, the first electric push rod 9 pushes the push rod 9 to move backward, driving the adjusting block 10 to move until the adjusting block 10 is engaged into the rhombic card slot formed on the surface of the rotating cylinder 752.
[0026] Working principle: When using the marine rescue unmanned boat, when someone is found drowning at sea, first, the turbine driver 3 is used to drive the hull 1 to move towards the drowning person. The remote control is used to place the clamping arms 2 on both sides of the drowning person. The first electric push rod 9 inside the hull 1 is controlled to pull the push rod 9 to move forward inside the sleeve rod 8 towards the front side of the hull 1, so that the adjusting block 10 is engaged into the rhombic card slot formed on the surface of the driving bevel gear 73. The driving motor is used to drive the second pulley 72 to rotate. The rotation of the second pulley 72 drives the first pulley 71 to rotate. The rotation of the first pulley 71 drives the sleeve rod 8 to rotate. The rotation of the sleeve rod 8 drives the adjusting block 10 to rotate. The rotation of the adjusting block 10 drives the driving bevel gear 73 to rotate. The rotation of the driving bevel gear 73 drives the driven bevel gear group 74 to rotate, and further drives the rotating rod 61 to rotate. While the rotating rod 61 rotates, it cooperates with the convex block 66 inside the moving block 63, so that the moving block 63 moves along the guiding groove 65 towards the sleeve 64. The movement of the moving block 63 drives the connecting rod 67 to rotate, and further makes the gripping blocks 68 on the clamping arms 2 at both ends of the rear side of the hull 1 approach the drowning person until the drowning person is clamped to prevent him from sinking due to lack of physical strength. At this time, the convex block 66 is in the sliding groove. While clamping the drowning person, the insertion block 691 on one side of the top of the moving block 63 is inserted into the corresponding slot 692 at the bottom of the sleeve 64. The insertion block 691 is locked by the clamping blocks 695 on the first piston rods 694 on both sides inside the slot 692, so that the gripping block 68 is always in the gripping state. The driving motor is used to drive the lead screw 62 to rotate, driving the sleeve 64 to move towards the hull 1. The movement of the sleeve 64 drives the moving block 63 to move towards the hull 1 along the sliding groove synchronously, so that the gripping block 68 drives the drowning person to move towards the hull 1 along the limit sliding groove; While the gripping block 68 moves the drowning person along the limiting slide toward the hull 1, the second electric push rod 9 pushes the support plate 4 to move upward, slowly lifting the drowning person, further reducing the loss of physical strength of the drowning person. The pressure detector installed in the support plate 4 will detect the weight of the drowning person, and then control the first electric push rod 9 to push the push rod 9 to move backward, driving the adjustment block 10 to move until the adjustment block 10 is stuck in the prismatic groove on the surface of the rotating drum 752, and then control the driving motor to drive the second pulley 72 to rotate, the rotation of the second pulley 72 drives the first pulley 71 to rotate, the rotation of the first pulley 71 drives the sleeve rod 8 to rotate, the rotation of the sleeve rod 8 drives the adjustment block 10 to rotate, the rotation of the adjustment block 10 drives the rotating drum 752 to rotate, the rotation of the rotating drum 752 causes the guide rod to move back and forth along the guide block through the groove at the top, and then drives the resistance block 753 back and forth The movement causes the output end of the second piston rod 755 to move along the inclined surface of the resistance block 753, causing the second piston rod 755 to move back and forth in the air cylinder 754, and cooperates with the one-way valve on the second piston rod 755 to press air into the air bag 5 on the top of the support plate 4 through the air pipe, thereby improving the comfort of the rescue boat, avoiding the hull 1 from shaking and causing secondary injuries to the drowning person during the rescue process, and at the same time improving the buoyancy and increasing stability. Finally, the turbine drive 3 drives the hull 1 to sail to the shore with the drowning person, and the driving motor drives the sleeve 64 to move toward the rear side of the hull 1, driving the clamping block 695 to move on the surface of the telescopic block 693, so that it moves to the surface of the plug block 691 to slide, and then the plug block 691 is disengaged from the inside of the slot 692, so that the sleeve 64 and the moving block 63 are unlocked, and then the gripping block 68 is released from the gripping state, and the drowning person is further rescued.
