Description

Technical Field

[0001] The invention belongs to the technical field of marine equipment, and in particular relates to a compact lifeboat quick-releasing device. Background Art

[0002] The compact lifeboat quick release device is an auxiliary device for emergency life-saving equipment on board ships, designed to achieve the purpose of rapid release of lifeboats in emergency situations; Traditional lifeboat release systems involve securely hooking a chain from the top of a skid to the stern of a lifeboat. This physical connection secures the lifeboat to the top of the skid, keeping it in a standby position. When an emergency situation arises and the lifeboat needs to be released, the operator unlocks the release mechanism. Once unlocked, the chain disengages from the hook, securing the lifeboat. The lifeboat then slides down the skid under its own weight, landing on the sea surface, completing the release process.

[0003] However, this traditional release mechanism has exposed numerous problems in practical use. Most notably, most still rely on manual operation. Even for compact lifeboats, despite their relatively small size, their weight is significant. In emergencies, crew members often face immense psychological pressure and time constraints, making manually releasing such a heavy lifeboat a significant challenge. The operator also expends considerable physical effort and energy operating the release mechanism, significantly reducing the efficiency of the lifeboat's release in emergencies.

[0011] Preferably, it also includes: The guide assembly is arranged at the bottom end of the mounting frame. The guide assembly includes a fixed groove opened at the bottom end of the mounting frame. A guide block is slidably connected inside the fixed groove, and the top of the guide block is fixedly connected to the fixed block.

[0012] Preferably, the number of the fixing blocks is two, and the two fixing blocks are designed to be longitudinally symmetrical about the center of the mounting frame, and one side end of the two fixing blocks away from the center of the mounting frame is chamfered.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the present invention provides a compact lifeboat quick release device, comprising a base 1 and a mounting frame 2, and further comprising: A rotating mechanism 3 is provided on one side of the mounting frame 2; The rotating mechanism 3 includes a hook 301 rotatably connected to the interior of the mounting frame 2. A gear 1 302 located on one side of the rotating mechanism 3 is fixedly mounted on one side of the hook 301. An extrusion plate 303 is fixedly mounted on one side of the gear 1 302. A fixed shell 304 is fixedly mounted on one side of the mounting frame 2. A sliding plate 305 is slidably connected to the interior of the fixed shell 304, and the extrusion plate 303 contacts the sliding plate 305. The fixed shell 304 and the sliding plate 305 are elastically connected via an elastic member 306. The driving assembly 4 is disposed at the bottom end of the mounting frame 2 and can drive the gear 1 302 to rotate.

[0022] With the above solution, the operator can install the mounting bracket 2 inside the base 1, and then install the base 1 on the tail of the lifeboat. Then, the operator can use a chain to hook the hook 301 to fix the lifeboat on the top of the sliding rack. When the lifeboat needs to be released, the driving assembly 4 is driven to rotate the gear 1 302, which in turn drives the extrusion plate 303 to rotate. The extrusion plate 303 pushes the sliding plate 305 to rotate inside the fixed shell 304. When the sliding plate 305 rotates, the elastic member 306 is compressed. By utilizing the resilience of the elastic member 306, the gear 1 302 and the extrusion plate 303 can be reset, and then the gear 1 302 will drive the hook 301 to rotate. When the hook 301 rotates, the chain used to fix it will be separated from the inside of the hook 301, and then the lifeboat will slide onto the sea surface along the sliding rack, thereby completing the release operation. Finally, by driving the driving component 4 to rotate the hook 301, the chain gradually breaks away from the restraint of the hook 301, thereby improving the release efficiency of the lifeboat in an emergency and buying precious time for people to escape.

[0023] like Figure 3 As shown, the drive assembly 4 includes a motor 401 fixedly connected to the bottom end of the mounting frame 2, a threaded rod 402 is fixedly mounted on the output end of the motor 401, a threaded block 403 is threadedly sleeved on the surface of the threaded rod 402, and a rack 404 engaged with the gear 302 is fixedly mounted on one side of the threaded block 403.

[0024] The above solution is adopted: through the design of the driving component 4, the motor 1 401 can be driven to rotate the threaded rod 402. Since the threaded rod 402 is threadedly connected to the threaded block 1 403, the threaded block 1 403 will slide on the surface of the threaded rod 402, and the threaded block 1 403 will drive the rack 404 to move. Since the rack 404 is engaged with the gear 1 302, during the movement, the gear 1 302 and the hook 301 will be driven to rotate, so that the chain is freed from the restraint of the hook 301.

[0025] like Figure 4 and Figure 5 As shown, it also includes: The vibration mechanism 5 is arranged on one side of the mounting frame 2. The vibration mechanism 5 includes a gear 2 501 rotatably connected to one side of the mounting frame 2, and the gear 2 501 is engaged with the rack 404. A worm 502 is fixedly installed on one side of the gear 2 501. A worm wheel 503 engaged with the worm 502 is rotatably connected to one side of the mounting frame 2. A sliding ring 505 is provided on one side of the worm wheel 503. A push rod 504 located inside the sliding ring 505 is fixedly installed on one side of the worm wheel 503. An impact block 506 is fixedly installed on one side of the sliding ring 505 close to the surface of the mounting frame 2.

[0026] The above solution is adopted: through the design of the vibration mechanism 5, when the rack 404 moves, because the rack 404 is engaged with the gear 2 501, it will drive the gear 2 501 to rotate, and the gear 2 501 will drive the worm 502 to rotate. Since the worm 502 is engaged with the worm wheel 503, the worm 502 will drive the worm wheel 503 to rotate, and the worm wheel 503 will drive the push rod 504 to slide inside the sliding ring 505. During the sliding process, the sliding ring 505 and the impact block 506 will be driven to move back and forth. When the impact block 506 moves, it will hit the surface of the mounting frame 2. The impact force generated by the impact will act on the gap between the mounting frame 2 and the hook 301, shaking off the stubborn rust, allowing the originally stuck hook 301 to rotate smoothly, thereby improving the release efficiency.

[0027] like Figure 7 and Figure 8 As shown, it also includes: The fixing mechanism 6 is arranged inside the bottom end of the mounting frame 2. The fixing mechanism 6 includes a second motor 601 fixedly connected to the inside of the bottom end of the mounting frame 2. The output end of the second motor 601 is fixedly installed with a bidirectional screw rod 602. The surface thread of the bidirectional screw rod 602 is threadedly sleeved with a second threaded block 603. The interior of the mounting frame 2 is slidably connected to a fixed block 604 located inside the base 1. The fixed block 604 and the second threaded block 603 are hinged by a hinge rod 605.

[0028] With the above solution, through the design of the fixing mechanism 6, when the equipment needs to be maintained, the second motor 601 can be driven to rotate the bidirectional screw rod 602. Since the bidirectional screw rod 602 is threadedly connected to the second threaded block 603, and the fixing block 604 is hinged to the second threaded block 603 through the hinged rod 605, the two second threaded blocks 603 will move toward each other. During the movement, the hinged rod 605 will be driven to rotate. The rotating hinged rod 605 will pull the fixing block 604 away from the inside of the base 1, thereby removing the limit on the mounting frame 2. Then, the entire mounting frame 2 can be disassembled and then maintained. After the maintenance is completed, the mounting bracket 2 can be reinserted into the interior of the base 1, and then the motor 2 601 can be driven again to make the bidirectional screw rod 602 rotate in the opposite direction, and the threaded block 2 603 will drive the hinged rod 605 to rotate in the opposite direction, and the hinged rod 605 will push the fixed block 604 to re-enter the interior of the base 1 to fix it. Finally, by driving the motor 2 601 to make the fixed block 604 enter or move away from the interior of the base 1, the mounting bracket 2 can be quickly disassembled and installed, thereby improving the convenience of the equipment.

[0029] like Figure 3 As shown, it also includes: The limiting assembly 7 is arranged on one side of the mounting frame 2. The limiting assembly 7 includes a slide rail 701 fixedly connected to one side of the mounting frame 2. The surface of the slide rail 701 is slidably fitted with a limiting block 702, and one side of the limiting block 702 is fixedly connected to the threaded block 403.

[0030] Adopting the above solution: through the design of the limit assembly 7, when the threaded block 403 moves, it will drive the limit block 702 to slide on the surface of the slide rail 701, and the slide rail 701 and the limit block 702 can limit the threaded block 403, thereby ensuring the stable movement of the threaded block 403.

[0031] like Figure 5 and Figure 6 As shown, it also includes: The support assembly 8 is arranged on one side of the mounting frame 2. The support assembly 8 includes a protective shell 801 fixedly connected to one side of the mounting frame 2. A support plate 802 is fixedly installed on one side inside the protective shell 801. A support slider 803 is slidably connected inside the support plate 802, and the top end of the support slider 803 is fixedly connected to the bottom end of the sliding ring 505.

[0032] The above solution is adopted: through the design of the support component 8, when the push rod 504 pushes the sliding ring 505 to move, it will drive the support slider 803 to slide inside the support plate 802. During the sliding process, the sliding ring 505 can be moved and limited, and the protective shell 801 is arranged on the surface of the rotating mechanism 3, the driving component 4 and the vibration mechanism 5, thereby being able to protect their components.

[0033] like Figure 8 As shown, it also includes: The guide assembly 9 is arranged at the bottom end inside the mounting frame 2. The guide assembly 9 includes a fixed groove 901 opened at the bottom end inside the mounting frame 2. The inside of the fixed groove 901 is slidably connected to a guide block 902, and the top of the guide block 902 is fixedly connected to the fixed block 604.

[0034] Adopting the above solution: through the design of the guide component 9, when the fixed block 604 moves, it will drive the guide block 902 to slide inside the fixed groove 901. Since the surface of the guide block 902 fits with the inner wall of the fixed groove 901, it can limit the fixed block 604 and ensure the stability of the movement of the fixed block 604.

[0035] like Figure 7 and Figure 8 As shown, there are two fixing blocks 604 , and the two fixing blocks 604 are designed to be longitudinally symmetrical about the center of the mounting frame 2 , and one side end of the two fixing blocks 604 away from the center of the mounting frame 2 is chamfered.

[0036] The above solution is adopted: through the design of the fixing block 604, since the fixing block 604 is symmetrically designed, the stability of the fixing of the mounting frame 2 can be ensured, and the end of the fixing block 604 away from the center of the mounting frame 2 is chamfered, which facilitates the design of the fixing block 604 entering the base 1.

[0037] like Figure 4 As shown, a gap is designed between the gear 1 302 and the extrusion plate 303 , and the gear 1 302 is located on one side of the fixed shell 304 . The elastic member 306 is arc-shaped, and the surface of the sliding plate 305 fits the inner wall of the fixed shell 304 .

[0038] The above solution is adopted: through the design of the extrusion plate 303, since there is a gap designed between the gear 1 302 and the extrusion plate 303, the rotation of the gear 1 302 is not interfered with, and the fixed shell 304 is located on one side of the fixed shell 304, which is convenient for pushing the sliding plate 305 to move. Through the design of the sliding plate 305 and the elastic member 306, since the surface of the sliding plate 305 fits with the inner wall of the fixed shell 304, the sliding plate 305 can slide along the inner wall of the fixed shell 304, ensuring that the sliding plate 305 can move stably.

[0039] The working principle and use process of the present invention: First, the operator installs the base 1 on the stern of the lifeboat through bolts, and then the base 1 can be installed on the stern of the lifeboat, and then the hook 301 is hooked with a chain to fix the lifeboat on the top of the sliding frame. When the lifeboat needs to be released, the driving motor 1 401 rotates the threaded rod 402, and the threaded block 1 403 slides on the surface of the threaded rod 402. The threaded block 1 403 drives the rack 404 to move, and the rack 404 drives the gear 2 501 and the worm 502 to rotate. The worm 502 drives the worm wheel 503 and the push rod 504 to rotate. The push rod 504 drives the sliding ring 505 and the impact block 506 to reciprocate. When the impact block 506 moves, it hits the surface of the mounting frame 2. The impact force generated by the impact is used to shake off the stubborn rust, ensuring the stability of the rotation of the hook 301. Furthermore, the rack 404 also drives the gear 1 302 to rotate, which in turn drives the extrusion plate 303 to rotate. The extrusion plate 303 pushes the sliding plate 305 to rotate inside the fixed housing 304. When the sliding plate 305 rotates, the elastic member 306 is compressed. The elastic member 306 is used to restore the gear 1 302 and the extrusion plate 303. Then, the gear 1 302 drives the hook 301 to rotate. When the hook 301 rotates, the fixing chain is released from the hook 301, and the lifeboat slides onto the sea surface along the sliding frame. When the mounting frame 2 needs to be maintained, the driving motor 2 601 rotates the bidirectional screw 602, and the two threaded blocks 2 603 move toward each other. During the movement, the hinge rod 605 is driven to rotate, and the rotating hinge rod 605 pulls the fixed block 604 away from the inside of the base 1, thereby canceling the limit on the mounting frame 2. Then the entire mounting frame 2 can be disassembled and maintained, and the operation process is finally completed.
