Description

Technical Field

[0001] This invention relates to the technical field of rescue equipment, specifically a ship rescue basket. Background Technology

[0002] During navigation, ships must be equipped with emergency rescue equipment to deal with emergencies such as grounding, collisions, and fires. Lifesaving baskets are crucial tools for transferring and rescuing personnel at sea, and their performance directly affects rescue efficiency and safety. Existing shipboard lifesaving baskets have several shortcomings: their fixed structure, with the central pole and frame often being an integrated design that cannot be folded or extended, requires significant deck or storage space when not in use, contradicting the ship's limited storage space requirements; their rescue convenience is poor, with protective frames often at a fixed height, making it difficult for people in the water (especially those who are physically exhausted, injured, or wearing life jackets) to climb into the basket, potentially delaying rescue efforts; and the existing baskets have no adjustable volume. When a large number of people need to be rescued or emergency supplies need to be carried, the fixed volume of the basket cannot be flexibly expanded, leading to increased rescue frequency and significantly reduced efficiency. Therefore, there is an urgent need for a shipboard lifesaving basket that combines convenient storage with flexible rescue capabilities. Summary of the Invention

[0003] The purpose of this invention is to provide a marine life-saving basket to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a ship's life-saving basket, comprising:

[0005] The bottom of the suspended platform, the main body of which is the platform base frame, is a welded and assembled metal structure. The surface of the platform base frame is coated with an anti-corrosion coating. Similarly, other parts of the suspended platform requiring corrosion resistance also need anti-corrosion treatment. The platform base frame consists of several support plates. Figure 2 It is known that there are six support plates, and the ends of the six support plates are welded to the central disc. Branch rods are set between the support plates. The branch rods can be fixed to the side of the support plates by welding. The density of the branch rods can be changed, as long as it can provide a place for the rescued people to step. The branch rods and support plates together form the bottom of the basket.

[0006] The center rod is installed at the center of the bottom of the suspended platform and is bolted for easy assembly and disassembly. The top of the center rod is provided with a connection structure for connecting the lifting device, which can be a hook or other structure. This is a common technical means and will not be described in detail.

[0007] The frame includes a border section installed on the edge of the suspended platform base. The border section is provided with an array of adjustable border components. The number of border components depends on the shape of the suspended platform base and can be adjusted adaptively.

[0008] Preferably, the central rod is a telescopic structure to reduce storage volume when stored.

[0009] Preferably, the frame assembly includes two mounting posts, which are welded and assembled metal tubular structures. A float mounting frame is provided at the top of each of the two mounting posts, and several float balls are mounted on the float mounting frame. The number and volume of the float balls are not limited, as long as the buoyancy of all the float balls is sufficient to support the entire basket and the personnel inside. A metal rod is provided between the two mounting posts, and a connecting strap is provided between the top of the metal rod and the top of the central rod. The connecting strap is used to reinforce the basket, making it more stable during use. The connecting strap is made of chain or other relatively strong material, and the two ends of the connection can be detached.

[0010] Preferably, the bottom of the mounting column is provided with a bottom connecting column, and a bottom groove is opened at the edge of the suspended platform base. The bottom of the mounting column is located in the bottom groove, and both ends of the bottom connecting column are rotatably inserted into the bottom groove through bearings. The bottom connecting column is a structure of upper and lower welded assembly and has a hollow internal structure. A connecting piece is movably inserted into one end of the bottom connecting column. The connecting piece has a cross-shaped structure, and a cross-shaped hole groove adapted to the connecting piece is provided on this end of the bottom connecting column. An internal fixing block is provided inside the bottom connecting column, and a first airbag is connected between one side of the internal fixing block and the connecting piece. A tension spring is fitted around the outside of the first airbag. A second airbag is located on the top of the inner fixing block and inside the mounting column. The inner fixing block has a channel connecting the first and second airbags. An inner slider is located on the top of the second airbag and slides inside the mounting column. A rotating block is rotatably connected to the top of the inner slider. A lever is welded to the side of the rotating block. A lever limiting groove is opened on the side wall at the bottom of the mounting column. The lever extends out from the lever limiting groove. A limiting sleeve is welded and fixed inside the edge of the hanging basket base frame. The limiting sleeve has a cross-shaped groove corresponding to the docking part.

[0011] Preferably, an adjustable protective component is provided on the frame assembly.

[0012] Preferably, the protective assembly includes two symmetrically arranged side rods, a grid mesh between the two side rods, a lifting block slidably arranged inside the upper end of the mounting column, a push spring connected to the bottom of the lifting block, the bottom of the push spring being fixed to a baffle inside the mounting column, a square groove opened on the upper side wall of the mounting column, a connector between the lifting block and the side rods, a sliding sleeve slidably fitted on the outside of the mounting column, a sliding groove opened on the other side wall of the mounting column, the sliding sleeve and the lifting block being welded together by a metal sheet passing through the sliding groove. All these structures are made of metal and are assembled by welding. Two sets of locking components are provided on the side wall of the side rods, and a mounting groove is provided at the bottom of the side rods, with a secondary locking component installed in the mounting groove.

[0013] Preferably, the grid mesh is a mesh structure, which is a metal mesh or synthetic fiber mesh welded to the side walls of the two side rods. If the grid mesh is a synthetic fiber mesh, materials with good corrosion resistance such as nylon rope, polyester rope or polypropylene rope can be used. Hole rings for fixing the rope need to be welded on the side walls of the side rods.

[0014] Preferably, the connecting member is two metal rods that are hinged together, and the two metal rods are respectively rotatably mounted on the lifting block and the side wall of the side rod.

[0015] Preferably, the two sets of locking components have the same structure. Each locking component includes a connecting plate. The connecting plates in the two sets of locking components have different lengths. One end of the connecting plate is rotatably mounted on the side wall of the side rod via a rotating shaft. The other end of the connecting plate is provided with a mounting plate. A torsion pin is inserted into the mounting plate. The torsion pin and the mounting plate are connected by internal and external threads.

[0016] Preferably, the secondary locking component includes a mounting sleeve, the side wall of which is rotatably mounted in a mounting groove via a pivot, a positioning rod is inserted into the mounting sleeve, the positioning rod is threaded, and the positioning rod and the mounting sleeve are connected by internal and external threads.

[0017] Preferably, the sliding sleeve is provided with locking holes corresponding to the torsion bar and the positioning rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention proposes a shipboard rescue basket with a telescopic or foldable and detachable central pole and a rotatable and retractable frame assembly. When not in use, it significantly reduces its volume, saving ship storage space and adapting to the limited storage environment of ships. The basket's base frame and metal components are coated with an anti-corrosion coating, and the mesh is made of metal or corrosion-resistant synthetic fibers such as nylon or polyester rope, precisely adapting to the high-salt and high-humidity marine environment, extending the equipment's service life and reducing maintenance costs. The protective components can be pressed down to form an opening, facilitating entry for exhausted personnel who have fallen into the water. The capacity can be expanded by adjusting the connecting and locking components to accommodate the needs of multiple personnel and supplies rescue. A buoy ball ensures the basket's buoyancy, and connecting straps enhance structural stability, further improving rescue safety and efficiency.

[0020] 2. When the suspended platform is not in use for storage, the frame assembly is in a horizontal state. Removing the connecting strap and center rod significantly reduces storage space. In use, install the center rod, then rotate the mounting post to adjust the frame assembly to a vertical state. Slide the lever downwards along the lever limiting groove and fix it in the slot at the bottom of the lever limiting groove. At this time, the second airbag is compressed, allowing air from inside the second airbag to enter the first airbag. The first airbag expands and extends, pushing the connecting piece so that its end extends into the cross-shaped slot of the limiting sleeve, thus fixing the mounting post. The frame assembly can then be adjusted to a vertical state. Finally, fix the connecting strap for use.

[0021] 3. When using the gondola for rescue, the gondola needs to be placed in the water and float on the surface. The person who has fallen into the water needs to enter the gondola. Because it is equipped with an adjustable protective component, the protective component can be pressed down. The side bar is installed on the lifting block and the sliding sleeve. The lifting block and the sliding sleeve slide down on the mounting column, thereby causing the protective component to descend. An opening is opened on the side of the gondola, and the trapped person can directly enter the gondola from this point. This avoids the situation where people with poor swimming skills or exhaustion have difficulty climbing over the gondola frame, making it more convenient.

[0022] 4. When the rescue personnel or the supplies carried cause congestion in the gondola, it is necessary to increase the gondola's capacity. This can be achieved by separating the shorter locking piece from the sliding sleeve, turning the torsion pin to disengage it from the locking hole on the sliding sleeve, pushing the protective assembly outward to change the connecting piece from a bent state to an extended state, and then fixing the longer locking piece to the corresponding locking hole on the sliding sleeve. Then, rotate the mounting sleeve to align the positioning rod with the locking hole on the sliding sleeve, and rotate the positioning rod to fix it to the sliding sleeve. At this point, the protective assembly can be fixed, thereby increasing the gondola's volume and allowing it to carry more personnel or supplies. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 13 This invention provides a technical solution: a shipboard life-saving basket, see reference. Figure 1 and Figure 2 The suspended platform consists of a bottom, a central rod 2, and a frame. The main body of the bottom is the platform base frame 1, which is a welded and assembled metal structure. The surface of the platform base frame 1 is coated with an anti-corrosion coating. Similarly, other parts of the suspended platform requiring corrosion resistance also need anti-corrosion treatment. The platform base frame 1 is composed of several support plates. Figure 2 It is known that there are six support plates, and the ends of the six support rods are welded to the central disc. Branch rods are set between the support plates. The branch rods can be fixed to the side of the support plates by welding. The density of the branch rods can be changed, as long as it can provide a place for the rescued people to step. The branch rods and support plates together form the bottom of the basket.

[0039] The central rod 2 is a telescopic structure to reduce storage volume when stored. The bottom of the central rod 2 is installed at the center of the bottom of the basket and is bolted for easy assembly and disassembly. The top of the central rod 2 is provided with a connection structure for connecting lifting devices, such as hooks, to facilitate connection of lifting devices, rescue helicopters, etc. This is a common technical means and will not be described in detail. The frame part is installed on the edge of the basket base 1. The frame part is provided with an array of adjustable frame components. The number of frame components is determined according to the shape of the basket base 1 and can be adjusted adaptively.

[0040] See Figure 1 and Figure 3 The frame assembly includes two mounting posts 3, which are welded and assembled metal tubular structures. A float mounting frame 15 is set on the top of the two mounting posts 3. Several float balls 16 are installed on the float mounting frame 15. The number and volume of the float balls 16 are not limited, as long as the buoyancy of all the float balls 16 can support the entire basket and the personnel inside. A metal rod is set between the two mounting posts 3. A connecting strap is set between the top of the metal rod and the center rod 2. The connecting strap is used to reinforce the basket and make it more stable during use. The connecting strap is made of chain or other strong materials, and the two ends of the connection can be removed.

[0041] See Figures 4-6The bottom of the mounting column 3 is provided with a bottom connecting column 4. A bottom groove is opened at the edge of the suspended platform base 1. The bottom of the mounting column 3 is located in the bottom groove, and both ends of the bottom connecting column 4 are rotatably inserted into the bottom groove through bearings. The bottom connecting column 4 is a structure of upper and lower welded assembly and has a hollow internal structure. A connecting piece 5 is movably inserted into one end of the bottom connecting column 4. The connecting piece 5 has a cross-shaped structure. A cross-shaped hole groove adapted to the connecting piece 5 is provided on this end of the bottom connecting column 4. An internal fixing block 6 is provided inside the bottom connecting column 4. A first airbag 8 is connected between one side of the internal fixing block 6 and the connecting piece 5. A tension spring 7 is sleeved on the outside of the first airbag 8. Spring 7 applies tension to the docking part 5. A second airbag 9 is provided on the top of the inner fixing block 6. The second airbag 9 is located inside the mounting column 3. The inner fixing block 6 is provided with a channel connecting the first airbag 8 and the second airbag 9. An inner slider 10 is provided on the top of the second airbag 9. The inner slider 10 is slidably disposed inside the mounting column 3. A rotating block 11 is rotatably connected to the top of the inner slider 10. A lever 12 is welded to the side of the rotating block 11. A lever limiting groove 14 is opened on the side wall at the bottom of the mounting column 3. The lever 12 extends out from the lever limiting groove 14. A limiting sleeve 13 is welded and fixed inside the edge of the hanging basket base frame 1. A cross-shaped slot corresponding to the docking part 5 is provided on the limiting sleeve 13.

[0042] When the suspended platform is not in use for storage, the frame assembly is in a horizontal state. At the same time, the connecting strap and center rod 2 can be removed, which can greatly reduce the storage space. When in use, the center rod 2 is installed, and then the mounting column 3 is rotated to adjust the frame assembly to a vertical state. The lever 12 is slid down along the lever limiting groove 14 and fixed in the bayonet at the bottom of the lever limiting groove 14. At this time, the second airbag 9 is compressed, so that the air inside the second airbag 9 enters the first airbag 8. The first airbag 8 expands and extends, pushing the docking piece 5 so that the end of the docking piece 5 can extend into the cross-shaped slot of the limiting sleeve 13, thereby fixing the mounting column 3. The frame assembly can then be adjusted to a vertical state. Finally, the connecting strap is fixed and it can be used.

[0043] See Figures 7-12An adjustable protective component is provided on the frame assembly. The protective component includes two symmetrically arranged side rods 17, and a grid mesh 18 is provided between the two side rods 17. The grid mesh 18 has a mesh structure and is a metal mesh or synthetic fiber mesh welded to the side walls of the two side rods 17. If the grid mesh 18 is a synthetic fiber mesh, it can be made of materials with good corrosion resistance such as nylon rope, polyester rope or polypropylene rope. Hole rings for fixing the rope need to be welded on the side walls of the side rods 17. A lifting block 19 is slidably installed inside the upper end of the mounting column 3. A push spring 20 is connected to the bottom of the lifting block 19. The bottom of the push spring 20 is fixed to the baffle inside the mounting column 3. A square groove is opened on the upper side wall of the mounting column 3. A connector 21 is provided between the lifting block 19 and the side rod 17. The connector 21 consists of two metal rods that are hinged together. A torsion spring is provided at the hinge. The elastic force provided by the torsion spring keeps the two metal rods in a bent state. The two metal rods are rotatably installed on the side walls of the lifting block 19 and the side rod 17, respectively. A sliding sleeve 22 is slidably fitted onto the outside of the mounting column 3. A sliding groove is provided on the other side wall of the mounting column 3. The sliding sleeve 22 and the lifting block 19 are welded together by a metal sheet passing through the sliding groove. These structures are all made of metal and are assembled by welding. Two sets of locking components 23 are provided on the side wall of the side rod 17. The locking components 23 have the same structure and include a connecting plate 2301. The connecting plates 2301 in the two sets of locking components 23 have different lengths. One end of the connecting plate 2301 is rotatably mounted on the side wall of the side rod 17 via a rotating shaft. The other end of the connecting plate 2301 is provided with a mounting plate 2302. A torsion column 2303 is inserted into the mounting plate 2302. The torsion column 2303 and the mounting plate 2302 are connected by internal and external threads. Multiple sets of locking components 23 can also be provided, such as two sets of short and two sets of long locking components 23, which can increase stability.

[0044] See Figure 13 A mounting groove is provided at the bottom of the side rod 17, and a secondary locking component is provided in the mounting groove. The secondary locking component includes a mounting sleeve 24, the side wall of which is rotatably mounted in the mounting groove via a pivot. A positioning rod 2401 is inserted into the mounting sleeve 24, and the positioning rod 2401 is threaded. The positioning rod 2401 and the mounting sleeve 24 are connected by internal and external thread engagement. A locking hole corresponding to the torsion pin 2303 and the positioning rod 2401 is provided on the sliding sleeve 22. By rotating the torsion pin 2303 or the positioning rod 2401, it can be inserted into the locking hole, thereby completing the fixed connection with the sliding sleeve 22.

[0045] When using the gondola for rescue, it needs to be lowered into the water and float on the surface. The person in the water needs to enter the gondola. Because it is equipped with an adjustable safety assembly, this assembly can be lowered. The side bar 17 is mounted on the lifting block 19 and the sliding sleeve 22. The lifting block 19 and the sliding sleeve 22 slide downwards on the mounting column 3, causing the safety assembly to descend. An opening is created on the side of the gondola, allowing the trapped person to directly enter the gondola. This avoids the difficulty for those with poor swimming skills or exhaustion to climb over the gondola's edge, making it more convenient. When rescuers or carrying supplies... When the suspended platform becomes congested, it is necessary to increase its capacity. This can be achieved by separating the shorter locking piece 23 from the sliding sleeve 22, twisting the torsion pin 2303 to disengage it from the locking hole on the sliding sleeve 22, pushing the protective component outward to change the connecting piece 21 from a bent state to an extended state, and then fixing the longer locking piece 23 to the corresponding locking hole on the sliding sleeve 22. Then, rotate the mounting sleeve 24 to align the positioning rod 2401 with the locking hole on the sliding sleeve 22, and rotate the positioning rod 2401 to fix it on the sliding sleeve 22. At this point, the protective component can be fixed, thereby increasing the volume of the suspended platform and allowing it to carry more personnel or materials.

[0046] This invention discloses a ship rescue basket designed to meet the practical needs of maritime emergency rescue. Through a rational structural design, it achieves a balance of practicality, durability, and flexibility. The basket consists of a basket base, a central rod 2, and a frame. The basket base 1 is made of welded metal and coated with an anti-corrosion layer. The central rod 2 is telescopic and foldable, and the frame components are rotatable for storage, solving the problems of traditional baskets being bulky and prone to corrosion. The frame is equipped with a float ball 16 to ensure buoyancy. The protective components, through lifting blocks 19, hinged connectors, and multi-level locking mechanisms, allow for easy access and flexible volume adjustment, adapting to different rescue scenarios. It is simple to operate, saves space when stored, and its anti-corrosion design is suitable for harsh marine environments. Its stable structure and flexible functions effectively improve the efficiency and safety of ship rescue, making it suitable for application in emergency rescue scenarios on various merchant ships, fishing vessels, and research vessels.
