Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a marine lifesaving device for ships. Background Art

[0002] The utility model with the publication number CN215361808U provides a marine lifesaving device for ships, comprising: a fixed shell, a driving motor is fixedly installed on the left side of the fixed shell, a lifebuoy is arranged below the fixed shell, a ring-arranged fixing belt is fixedly connected to the outer surface of the lifebuoy, and a connecting piece is fixedly connected to the end of each fixing belt away from the lifebuoy, a rotating shaft is arranged inside the fixed shell, a symmetrical first bearing is fixedly inlaid on the inner side wall of the fixed shell, and the left end of the rotating shaft is fixedly connected to the inner ring of a first bearing. The marine lifesaving device for ships is provided with three fixing belts on the lifebuoy, and the fixing belts are connected to the life rope through the connecting piece. When rescuing a person who falls into the water, the second gear is driven to rotate by the driving motor, and the meshing action of the first gear and the second gear is used to drive the reel wheel to reel in the thrown life rope, so that the life rope cooperates with the lifebuoy to rescue the person who falls into the water.

[0003] When the prior art is actually used, due to the influence of the meshing between the motor, the first gear and the second gear, the life rope needs to cooperate with the motor when it is unwound and stretched, so that the unwinding process takes a long time, which is not conducive to rescuing the drowning person in the first time. In addition, during the unwinding process, the life buoy is lowered vertically, so that the ship needs to get close to the drowning person to rescue, which reduces the lifesaving efficiency. Therefore, a marine lifesaving device for ships is needed to meet people's needs. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A marine lifesaving device for a ship comprises a first side plate 1 and a second side plate 2, a same winding roller 3 is rotatably installed between the first side plate 1 and the second side plate 2, a rescue rope 4 is wound on the winding roller 3, a lifebuoy 5 is connected to the end of the rescue rope 4, a frame 6 is arranged on the outer side of the first side plate 1, a motor 7 is arranged on the outer side of the frame 6, a first turntable 8 is arranged on the output shaft of the motor 7, a ratchet groove 9 is opened on the side of the first turntable 8 close to the first side plate 1, a second turntable 10 is connected to one end of the winding roller 3 located on the outer side of the first side plate 1, a rotating rod 11 is rotatably installed in the outer wall of the second turntable 10, one end of the rotating rod 11 is clamped in the ratchet groove 9, and a first spring 12 is connected between the rotating rod 11 and the second turntable 10.

[0022] When the lifebuoy 5 is thrown toward the drowning person, the rescue rope 4 is gradually stretched by the pulling force of the lifebuoy 5, so that the winding roller 3 rotates in the unwinding direction, driving the second turntable 10 to rotate, so that the rotating rod 11 rotates in the ratchet groove 9, so that the winding roller 3 can smoothly unwind the rescue rope 4. When the drowning person grabs the lifebuoy 5, the motor 7 is controlled to rotate, so that the first turntable 8 rotates. At this time, the ratchet groove 9 drives the rotating rod 11 to be connected. The elastic force of the first spring 12 ensures the connection between the rotating rod 11 and the ratchet groove 9, so that the first turntable 8 drives the second turntable 10 to rotate, thereby winding the rescue rope 4, quickly pulling the drowning person back, and achieving the purpose of lifesaving.

[0023] Specifically, in this embodiment, a slot 13 is provided on the outer wall of the second turntable 10, and both ends of the slot 13 do not pass through the two end planes of the second turntable 10. One end of the rotating rod 11 is rotatably installed in the slot 13, and one end of the first spring 12 is connected to the bottom inner wall of the slot 13. The slot 13 ensures the connection between the second turntable 10 and the rotating rod 11, and provides a storage space for the rotation of the rotating rod 11.

[0024] Specifically, in the present embodiment, the first side plate 1 and the second side plate 2 are provided with the same top plate 14, the top plate 14 is internally threadedly connected with a screw rod 15, a hand wheel 16 is provided on the top end of the screw rod 15, a connecting plate 17 is rotatably installed on the bottom end of the screw rod 15, a plurality of second springs 18 are provided on the bottom end of the connecting plate 17, a same pressing plate 19 is provided on the bottom ends of the plurality of second springs 18, and the pressing plate 19 is located above the winding roller 3. When the lifesaving device is not in use, the lifebuoy 5 is prone to unwinding the rescue rope 4 under the action of gravity. Through the cooperation among the screw rod 15, the connecting plate 17, the second spring 18 and the pressing plate 19, the pressing plate 19 presses the rescue rope 4 in the wound state to prevent the rescue rope 4 from loosening when not in use, and when rescue is needed, the screw rod 15 can be rotated so that the connecting plate 17 drives the pressing plate 19 away from the rescue rope 4.

[0025] Specifically, in this embodiment, a threaded hole 20 is opened in the top plate 14, and the screw rod 15 is threadedly connected in the threaded hole 20. The cooperation between the threaded hole 20 and the screw rod 15 realizes the stability of the pressure plate 19 pressing the rescue rope 4.

[0026] Specifically, in this embodiment, a T-shaped shaft 21 is provided on the bottom end of the screw rod 15, and the T-shaped shaft 21 is rotatably installed in the connecting plate 17. The T-shaped shaft 21 makes the rotation of the screw rod 15 and the movement of the connecting plate 17 independent of each other, and the connecting plate 17 can be pulled back smoothly when the screw rod 15 is reversed and retracted.

[0027] Specifically, in this embodiment, a plurality of guide rods 22 are provided on the top of the pressure plate 19. The guide rods 22 are located inside the second spring 18 and are slidably installed inside the connecting plate 17 and the top plate 14. The guide rods 22 ensure the stability of the pressure plate 19 and the connecting plate 17 during vertical movement.

[0028] Specifically, in the present embodiment, the bottom end of the pressing plate 19 is arc-shaped, which increases the contact area between the pressing plate 19 and the rescue rope 4, thereby increasing the friction and further preventing the rescue rope 4 from loosening.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
