[0019] Embodiment 2 is based on Embodiment 1 and is given by Figure 2 and Figure 4Given that the ejection drive structure includes a movable seat 7 disposed on the side of the pushing seat 6 away from the lifebuoy 35. On the side of the pushing seat 6 facing the movable seat 7, two second guiding columns 16 are fixedly connected. The second guiding columns 16 penetrate through the movable seat 7. The end of the second guiding column 16 away from the pushing seat 6 is fixedly connected with a second fixed disk 18. A second compression spring 17 is sleeved outside the second guiding column 16, and the two ends of the second compression spring 17 are respectively abutted against the pushing seat 6 and the movable seat 7. The release box 1 is fixedly installed with a second electric push rod 22. The telescopic end of the second electric push rod 22 is fixedly connected with a pressing disk 21 located inside the release box 1. And the third supporting part 27 is located on the side of the movable seat 7 away from the pushing seat 6. The release box 1 is equipped with a one-way translation mechanism for limiting the movement track of the movable seat 7. The one-way translation mechanism includes adjusting plates 8 respectively arranged above and below the movable seat 7. Sliding grooves 9 are respectively formed at the top end and the bottom end of the movable seat 7. Plug blocks 10 are slidably arranged in the sliding grooves 9. One end of the plug block 10 and the inner wall of the sliding groove 9 are connected by a first compression spring 11. The other end of the plug block 10 is located outside the sliding groove 9. Inclined surfaces are respectively arranged at the ends of the two plug blocks 10 away from each other.

And the telescopic end of the first electric push rod 20 is fixedly connected with the adjusting plate 8; When it is necessary to release the lifebuoy 35, the pressing disc 21 is driven to move by the second electric push rod 22. The pressing disc 21 pushes the movable seat 7 and the first guide post 13 to translate relative to the first support portion 14 and the release box 1. Since the position of the lifebuoy 35 and the pushing seat 6 is limited by the stop plate 4, at this time, the lifebuoy 35 and the pushing seat 6 remain stationary, the movable seat 7 slides relative to the second guide post 16, the second compression spring 17 is in a compressed state, and the movable seat 7 moves relative to the adjusting plate 8. The inclined surface on the insertion block 10 slides relative to the inner wall of the insertion slot 12. Finally, the insertion block 10 slides out of the insertion slot 12, and the first compression spring 11 is in a compressed state. When the insertion block 10 slides out of the insertion slot 12, as the movable seat 7 continues to move, the insertion block 10 moves to one side of the next insertion slot 12, and the first compression spring 11 pushes the end of the insertion block 10 to slide into the next insertion slot 12. When the distance between the movable seat 7 and the pushing seat 6 reaches a preset value, the pressing disc 21 stops pushing the movable seat 7 to move. The rotating mechanism drives the stop plate 4 to rotate so that the stop plate 4 no longer limits the position of the lifebuoy 35.

The iron plate 37 and the magnet block 24 are magnetically attracted to each other. The iron plate 37 and the swing plate 36 are fixed relative to the release box 1, preventing the swing plate 36 and the stop plate 4 from rotating and shaking relative to the release box 1. When the distance between the movable seat 7 and the pushing seat 6 reaches a preset value, the first electric push rod 20 drives the pressing plate 21 to move in the reverse direction. The pressing plate 21 no longer supports the movable seat 7, and the side of the insertion block 10 that is not the inclined surface abuts against the inner wall of the insertion slot 12. The movable seat 7 remains stationary at this position. When the first electric push rod 20 drives the pressing plate 21 to contact the movable frame 23, as the movable frame 23 continues to move, the movable frame 23 slides relative to the third guiding column 25, and the movable frame 23 drives the magnet block 24 to no longer be magnetically attracted to the iron plate 37, releasing the limitation on the positions of the swing plate 36 and the stop plate 4. The third compression spring 28 pushes the swing plate 36 to move, causing the swing plate 36 and the stop plate 4 to rotate. The stop plate 4 no longer limits the position of the lifebuoy 35. The second compression spring 17 drives the pushing seat 6 and the lifebuoy 35 to move. Finally, the second guiding column 16 drives the second fixed plate 18 to contact the movable seat 7, and the pushing seat 6 stops moving. The pushing seat 6 pushes the lifebuoy 35 to pop out from the release box 1. When the lifebuoy 35 needs to be filled into the release box 1, the first electric push rod 20 drives the adjusting plate 8 to move, causing the insertion block 10 to disengage from the insertion slot 12. The movable seat 7 can move towards the pressing plate 21. When the movable seat 7 is reset to the initial position relative to the pressing plate 21, the first electric push rod 20 drives the adjusting plate 8 to move towards the movable seat 7, causing the end of the insertion block 10 to be inserted into the corresponding insertion slot 12 again.
