[0035] The utility model provides a marine life-saving device, which aims to solve the problem that the operating range of the marine life-saving device is affected by the impact of waves and the rescue work is inconvenient when the rescue object is far away. Figures 1 to 6 The figure is a structural diagram of an embodiment of the marine lifesaving device provided by the present utility model.

[0036] Please refer to Figures 1 to 6 The utility model proposes a marine lifesaving device 100, including a bracket 1, a telescopic mechanism 2 and a lifting mechanism 3. The bracket 1 includes a pillar 11, a mounting arm 12 and a strut 13. The mounting arm 12 is arranged at one end of the pillar 11 and is inclined upward. The strut 13 is arranged on one side of the pillar 11 and connected to the mounting arm 12. The mounting arm 12 and the strut 13 respectively form a first accommodating cavity and a second accommodating cavity 131. The first accommodating cavity and the second accommodating cavity 131 are connected. The telescopic mechanism 2 includes a support 11, a mounting arm 12 and a support rod 13. The telescopic arm 21 and the first driving member 22 are provided. The telescopic arm 21 is slidably arranged in the first accommodating cavity. The first driving member 22 is provided on the support rod 13. At least part of the structure of the first driving member 22 is located in the first accommodating cavity. One end of the telescopic arm 21 is drivingly connected to the driving end of the first driving member 22. The lifting mechanism 3 includes a winch 31, a lifting rope 32 and a hook 33. The hook 33 is provided at the end of the telescopic arm 21 away from the mounting arm 12. The two ends of the lifting rope 32 are respectively connected to the winch 31 and the hook 33.

[0037] The technical solution of the present invention proposes a marine lifesaving device 100, comprising a bracket 1, a telescopic mechanism 2, and a hoisting mechanism 3. The bracket 1 comprises a support 11 and an outwardly extending mounting arm 12 provided on the support 11. The telescopic arm 21 of the telescopic mechanism 2 is provided on the mounting arm 12 and can be extended and retracted relative to the mounting arm 12. The telescopic mechanism 2 drives the extension and retraction of the telescopic arm 21 via a first driving member 22. The telescopic arm 21 is provided with a hook 33 at the farthest end relative to the mounting arm 12. The hook 33 is driven by a winch 31 and can be raised and lowered relative to the sea surface. When encountering severe turbulence caused by large waves due to bad weather, the telescopic arm 21 can be controlled to extend, thereby expanding the rescue range of the marine lifesaving device 100, ensuring that it can still achieve a good rescue effect when the hull is turbulent. When the lifesaving object is far away from the hull, the lifesaving object can also be rescued in a shorter time.

[0038] It should be noted that the present invention does not limit the specific structure of the telescopic mechanism 2. It can be a telescopic structure driven by a cylinder, a scissors-type telescopic structure, or a spiral telescopic structure. In one embodiment of the present invention, the telescopic mechanism 2 includes a telescopic arm 21 and a first driving member 22. The telescopic arm 21 is limited to the inner cavity of the mounting arm 12, that is, the first accommodating cavity. A rack 211 is provided on one side of the telescopic arm 21. The first driving member 22 is a motor. The driving end of the motor is connected to a gear, which engages with the rack 211 of the telescopic arm 21. When the motor is started, the gear drives the rack 211 to move, thereby causing the telescopic arm 21 to extend or retract relative to the mounting arm 12.

[0039] Furthermore, the motor has a large torque at the moment of startup. The large torque is instantly transmitted between the gear and the rack 211, causing the teeth to bear huge shear forces, seriously affecting the service life of the gear and rack 211. In view of this, the telescopic mechanism 2 also includes a transmission assembly 7, which includes a driving wheel 71, a transmission chain 72, and a driven gear 73. The driving wheel 71 is directly or indirectly connected to the output end of the first driving member 22. The transmission chain 72 is sleeved on the driving wheel 71 and the driven gear 73. The driven gear 73 is a structure composed of a concentric small wheel ring and a large gear ring, and is connected to the transmission chain 72 through the small wheel ring. The large gear ring is engaged with the rack 211 on the telescopic arm 21. When the motor starts, it will output torque to the rack 211 through the transmission assembly 7. The transmission assembly 7 will consume part of the torque through slip friction, thereby ensuring that the structure of the telescopic mechanism 2 is more reliable. Furthermore, a driving wheel 71 and a driven gear 73 with different gear ratios may be used to amplify the torque output by the motor, thereby enabling the telescopic arm 21 to be reliably extended and retracted even in a fully loaded state.

[0040] In order to achieve good guidance of the telescopic arm 21 in the extended and retracted states, a slide groove 121 is provided in the first accommodating cavity, and limiting grooves 122 are formed on both sides of the slide groove 121. Accordingly, the telescopic arm 21 is slidably arranged in the slide groove 121 and has limiting bosses 212 on both sides thereof. For details, please refer to Figure 4 Each limiting boss 212 is provided in a limiting groove 122. The cooperation between the limiting boss 212 and the limiting groove 122 ensures that the telescopic arm 21 can be controlled in its telescopic direction within the slide groove 121, providing a good guiding effect. The limiting boss 212 and the telescopic arm 21 body are integrally formed, ensuring its structural reliability.

[0041] In one embodiment of the present invention, the hook 33 is extended and retracted by a winch 31, that is, the hook 33 is raised and lowered relative to the water surface. Specifically, the winch 31 is provided on one side of the support 11, and the rope 32 on the winch 31 passes through the mounting arm 12 and the telescopic arm 21 in sequence and extends out from the end of the telescopic arm 21 away from the mounting arm 12. For details, please refer to Figure 1 Both the mounting arm 12 and the telescopic arm 21 are provided with rope holes for the passage of a lifting rope 32. The free end of the lifting rope 32 is connected to a hook 33. By controlling the winch 31 to pay out the line, the hook 33 is lowered to the same height as the rescued person, thereby rescuing the person. In addition, a more powerful winch 31 can be selected so that the device can also be used to lift cargo.

[0042] In order to reduce the friction between the suspension rope 32 and the mounting arm 12 and the telescopic arm 21, the mounting arm 12 is provided with a first pulley 34 and the telescopic arm 21 is provided with a second pulley 35. For details, please refer to Figure 3 The first pulley 34 and the second pulley 35 are respectively located in the first and second accommodating cavities 131. The pulleys provide a transition for the rope 32 to reduce friction between the rope 32 and the fixed structure, preventing wear of the rope 32. The rolling friction of the pulleys is lower than the sliding friction, which helps reduce resistance during payout, improve payout efficiency, and extend the service life of the rope 32. Both the first pulley 34 and the second pulley 35 are provided with an annular groove 351, which prevents the rope 32 from deviating from the pulleys, thereby limiting the rope 32.

[0043] To cover a wider operating area, the marine lifesaving device 100 also includes a base 4, with a support column 11 rotatably mounted on the base 4. The base 4 is fixed to the ship's deck or other offshore operating platform. When the support column 11 rotates relative to the base 4, the marine lifesaving device 100 can cover an operating range with a radius equal to the combined length of the mounting arm 12 and the telescopic arm 21, thereby increasing the rescue flexibility of the device. To further enhance the lifting capacity of the marine lifesaving device 100, a plurality of reinforcing ribs 41 are provided around the base 4. For details, please refer to the following. Figure 1 The reinforcing rib 41 and the base 4 are welded together to form a single structure. The reinforcing rib 41 can improve the supporting capacity of the base 4, thereby ensuring the reliability of the structure. It should be noted that the rotation of the support 11 relative to the base 4 is achieved by the second driving member 113. For details, please refer to Figure 1 and Figure 6 The base 4 is provided with a first bevel gear 42 facing the pillar 11, and the driving end of the second driving member 113 is provided with a second bevel gear 114. The first bevel gear 42 and the second bevel gear 114 are meshed and arranged at 90 degrees. The motor drives the pillar 11 to rotate on the base 4.

[0044] To independently control the operation of each mechanism and coordinate between them, the marine lifesaving device 100 also includes an electrical control box 5 . This box has different control modules for controlling the operation of different mechanisms. Furthermore, a control panel can be added to the box 5 to facilitate the operator's understanding of the device's real-time status and enable automated control. The box 5 is electrically connected to the first drive member 22 , the second drive member 113 , and the winch 31 . To facilitate operator control of the various mechanisms, a work platform 6 is provided on the support column 11 , allowing the operator to more conveniently perform control operations. A seat 61 is also provided on the work platform 6 , reducing operator fatigue, improving work efficiency and comfort, and helping the operator maintain a stable operating posture, ensuring accuracy and safety.

[0045] Considering that the use environment of the marine lifesaving device 100 is usually relatively harsh, with strong winds and large waves at sea, in order to prevent the hook 33 from swinging arbitrarily under the influence of crosswinds and causing safety hazards, a mooring ring 111 is provided on the side of the support 11 facing the telescopic arm 21. For details, please refer to Figure 3 The mooring ring 111 is provided with a cable 112, and the hook 33 is fixed to the mooring ring 111 by the cable 112 to prevent it from swinging and reduce safety hazards.

[0046] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
