Description

Technical Field

[0001] This invention relates to the field of lifeboat release device technology, and more particularly to a ship lifeboat release device. Background Technology

[0002] A lifeboat is a relatively effective escape tool installed on a ship to rescue crew members in the event of a shipwreck. While carrying its designated number of passengers, a lifeboat is also equipped with certain accessories and is a rigid dinghy capable of navigating or drifting in severe weather, maximizing the safety of crew and passengers. Fully enclosed lifeboats offer convenient access for crew, excellent watertightness, and reliable internal insulation, and have gained international recognition within the maritime community. The International Maritime Organization has designated them as essential life-saving equipment for passenger and cargo ships on international voyages.

[0003] Currently, ship lifeboat launch systems generally suffer from cumbersome operation, low launch efficiency, and poor adaptability, making them unsuitable for lifeboat deployment in complex sea conditions (such as wind, waves, and ship pitching). Specifically, this manifests in several ways: inflexible launch direction adjustment, leading to lifeboat collisions with the ship or failure to detach smoothly; unreasonable power transmission structure design, resulting in transmission lag and swaying, affecting launch stability; and some devices lack reliable emergency power supply and attitude detection mechanisms, potentially preventing lifeboat launches during mains power failures, posing a safety hazard. Furthermore, when large ships sink, a low-pressure vortex forms near the hull. Due to the ship's size and mass, smaller, lighter objects nearby are often drawn into the vortex, potentially posing a safety hazard to lifeboats near the wreck.

[0004] Therefore, how to design a ship lifeboat release device that can deploy lifeboats to a location far from the wreck while ensuring the comfort of the people inside the lifeboats has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a ship lifeboat release device to solve the problems listed in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a ship lifeboat release device, comprising a base plate, the lower surface of which is fixedly connected to the deck, and the upper surface of which is fixedly connected to the lower end of a support frame. The upper end of the support frame is fixedly connected to the outer side wall of the stator of the ring motor, and the inner side wall of the stator of the ring motor is magnetically connected to the outer side wall of the rotor of the ring motor. A swing assembly is fixedly installed on the inner side wall of the annular motor rotor; The swing component is fixedly connected to the delivery component.

[0007] Preferably, the oscillating assembly includes a drive unit and a gear unit, wherein the drive unit meshes with the gear unit.

[0008] Preferably, the drive unit includes a dual-head motor, and the output ends of the dual-head motor are respectively connected to the input end of the gearbox; The output end of the gearbox is fixedly connected to one end of the drive spindle, and the other end of the drive spindle is rotatably connected to the inner wall of the annular motor rotor through a main bearing; Furthermore, a drive tooth is fixedly installed on the outer circumferential surface of each drive spindle; It also includes a driven shaft, the two ends of which are rotatably connected to the inner sidewall of the annular motor rotor via a secondary bearing, and two driven gears are fixedly mounted in parallel on the outer circumferential surface of the driven shaft; The two driven gears mesh with each of the driving master teeth respectively.

[0009] Preferably, it also includes a fixing box, one end of which is connected to the foot of the dual-head motor, and the other end of which is fixedly connected to the inner sidewall of the annular motor rotor; The fixed box is internally sealed and equipped with a controller, a gyroscope, and a backup power supply, which are electrically connected to each other. The controller is electrically connected to the dual-head motor.

[0010] Preferably, the delivery component includes a carrying unit and a sliding unit, with the sliding unit fitted onto the outer peripheral surface of the carrying unit.

[0011] Preferably, the bearing unit includes a support rail, the lower surface of which is fixedly connected to a linear guide rail or magnetic guide rail; The ends of the support rail and the linear guide rail / magnetic guide rail are both fixedly connected to the moving gear.

[0012] Preferably, a guide groove is formed on each of the other three surfaces of the support rail along the axial direction.

[0013] Preferably, the sliding unit includes four connecting rings, with two connecting rings forming a group, and each group of connecting rings is respectively arranged on the support rail and the linear guide magnetic rail; Each of the connecting rings is rotatably mounted with three pulleys, and the pulleys cooperate with the guide groove; The lower end of each set of connecting rings is fixedly connected to both ends of the linear motor slider, and the linear motor slider is magnetically connected to the linear guide rail magnetic guide rail. The upper end of each set of connecting rings is fixedly connected to the bracket; A fixed support block is installed on the bracket, and the fixed support block abuts against the lower surface of the lifeboat; The lifeboat is fixedly connected to the hull by a rigging system. When escaping, the rigging system is unlocked, allowing the lifeboat to detach from the hull.

[0014] Preferably, the linear guide rail is electrically connected to the controller.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows: 1) The ring motor adopts a magnetic transmission structure for its stator and rotor, eliminating mechanical contact and ensuring smooth transmission with low noise and minimal wear. This allows for 360-degree flexible adjustment of the swing and delivery components, effectively preventing collisions between the lifeboat and the ship during deployment and ensuring a smooth detachment. The swing component uses a dual-head motor with a symmetrical gear transmission structure, ensuring precise power transmission and balanced force distribution. Based on real-time conditions such as ocean currents and wind direction, the controller and gyroscope work together to dynamically adjust the deployment angle, ensuring a stable deployment of the lifeboat and reducing the risk of deployment in complex sea conditions. Meanwhile, the elastic rubber support blocks on the bracket provide cushioning and protection for the lifeboat, preventing displacement or damage during swinging and sliding, further enhancing deployment safety. 2) The magnetic transmission between the linear guide rail, magnetic guide rail, and linear motor slider ensures fast response and precise positioning, enabling the lifeboat to slide quickly and smoothly along the support rail. This allows for rapid release of the lifeboat, placing it away from the wrecked vessel and preventing adverse effects from the wrecked ship. Simultaneously, the controller provides precise automatic control of the dual-head motor, linear guide rail, and magnetic guide rail, with a manual unlocking backup method. The operation is simple, requiring minimal personnel and significantly improving rescue efficiency in emergencies, buying precious time for people to escape at sea. The design of the guide groove and pulley reduces sliding friction, ensuring smooth deployment and further enhancing release efficiency. 3) The fixed box integrates a backup power supply, which can quickly provide emergency power to various electrical components in the event of a failure of the ship's main power supply, ensuring the normal operation of the lifeboat release device and avoiding the fatal hidden danger of lifeboats being unable to be released due to power failure; the gyroscope detects the attitude, swing angle and ship's rolling conditions of the device in real time, and transmits the signals to the controller to realize dynamic adjustment of the release angle and sliding speed, further improving the device's adaptability and emergency response capability in sudden working conditions; 4) The height of the support frame can be adapted to the installation height of the lifeboat and the deck space. The combination of the support rail, linear guide rail and magnetic guide rail can be adapted to the load-bearing requirements of lifeboats of different specifications. The device adopts magnetic transmission and sealed waterproof design to reduce mechanical wear and electrical failures. The maintenance process is simple and does not require frequent disassembly and maintenance, thus reducing maintenance costs. The overall structure is compact and occupies little deck space. It can be adapted to the installation requirements of different types of ships and has a wide range of applications.

[0016] In summary, the present invention provides a ship lifeboat release device that effectively solves the problems of cumbersome operation, low release efficiency, poor adaptability, and insufficient emergency response capabilities of existing lifeboat release devices. It has a reasonable structure and strong practicality, and can be widely used in the lifesaving systems of various types of ships. Moreover, it can stably deploy lifeboats even in complex sea conditions, achieving rapid, safe, and accurate release of lifeboats, ensuring the safety of personnel at sea, and providing reliable protection for the safety of personnel at sea.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-5As shown, a ship lifeboat release device includes a base plate 1, which is made of high-strength corrosion-resistant steel plate with a thickness adapted to the load-bearing requirements of the ship deck. Its lower surface is tightly fixed to the ship deck through a double fixing method such as welding and bolting, ensuring the overall stability of the device installation and preventing loosening or displacement under harsh conditions such as wind, waves, and ship turbulence. The upper surface of the base plate 1 is fixedly connected to the lower end of the support frame 2 by welding. The support frame 2 is made of stainless steel profile splicing, which has sufficient structural strength and corrosion resistance, and can stably support all components above. Its height can be adapted to the installation height of the lifeboat and the deck space to ensure smooth subsequent lifeboat deployment. The upper end of the support frame 2 is fixedly connected to the outer wall of the ring motor stator 3 by bolts, and the connection part is provided with a reinforcing shim to further improve the connection's firmness. The ring motor stator 3 adopts an embedded coil structure, and its inner wall is connected to the outer wall of the ring motor rotor 5 by magnetic transmission. This transmission method does not require mechanical contact and has the advantages of smooth transmission, low noise, low wear, and convenient maintenance. It can drive the ring motor rotor 5 to rotate 360° around the ring motor stator 3, thereby driving the subsequent swing component and delivery component to adjust their direction, adapting to the lifeboat delivery angle requirements under different sea conditions, facilitating the smooth detachment of the lifeboat from the deck, and ensuring that the lower surface of the lifeboat is in contact with the water surface during delivery, avoiding deviations in the incident angle of the lifeboat entering the water surface, which could adversely affect the crew inside the lifeboat. The inner wall of the annular motor rotor 5 is fixedly mounted with a swing assembly by bolts. As the core component for power transmission, the swing assembly can realize multi-angle swing adjustment of the delivery assembly, ensuring that the lifeboat can be aligned with the optimal delivery position when it is deployed. At the same time, the swing angle can be adjusted according to real-time conditions such as ocean currents and wind direction to improve the safety and accuracy of the deployment. The swing assembly is fixedly connected to the delivery assembly. Through the power transmission of the swing assembly, the delivery assembly is driven to complete the translation and deployment of the lifeboat, realizing a smooth transition of the lifeboat from the hull to the water surface.

[0022] Specifically, the swing assembly includes a drive unit and a gear unit. The drive unit provides stable power to the gear unit, and the drive unit and the gear unit mesh with each other to achieve precise power transmission through gear transmission, ensuring that the swing motion is smooth and controllable, avoiding problems such as power transmission lag and swaying, and ensuring the accuracy of swing angle adjustment.

[0023] Specifically, the drive unit includes a dual-head motor 4, which is waterproof and explosion-proof, suitable for the harsh environment of marine operations. Its output end is connected to the input end of two symmetrically arranged gearboxes via couplings. The gearboxes can adjust the output speed of the dual-head motor 4, converting the high-speed rotation of the motor into the low-speed, high-torque power required by the gear unit to meet the power requirements of the oscillating component. The output end of the gearbox is fixedly connected to one end of the drive spindle 7 via a flat key, and a locking nut is provided at the connection to prevent loosening during transmission. The other end of the drive spindle 7 is rotatably connected to the inner wall of the ring motor rotor 5 via a main bearing. The main bearing is a sealed waterproof bearing, which can effectively isolate seawater and moisture, prevent bearing corrosion and jamming, and ensure smooth rotation of the drive spindle 7. Furthermore, a drive gear 6 is fixedly installed on the outer circumference of each drive spindle 7 by interference fit. The drive gear 6 is made of high-strength gear steel, and the tooth surface is hardened to improve wear resistance and service life, ensuring the stability of power transmission. The swing assembly also includes a driven shaft 18, which is made of the same material as the drive shaft 7. Both ends of the driven shaft 18 are rotatably connected to the inner wall of the ring motor rotor 5 via secondary bearings. The secondary bearings also employ a sealed waterproof design to ensure that the driven shaft 18 rotates flexibly and without jamming. Two driven gears 8 are fixedly mounted parallel to each other on the outer circumference of the driven shaft 18. The two driven gears 8 are interference-fitted with the driven shaft 18 and correspond one-to-one with the two drive main gears 6. The two driven gears 8 mesh with each of the drive main gears 6, forming a symmetrical gear transmission structure. This structure allows the power of the dual-head motor 4 to be precisely transmitted to the driven shaft 18 through the drive main gears 6 and the driven gears 8, driving the driven shaft 18 to rotate synchronously, thereby driving the delivery assembly to achieve smooth swinging. Simultaneously, the symmetrical structure balances the forces during power transmission, preventing excessive force on one side from causing component damage and improving the overall stability and service life of the swing assembly.

[0024] Specifically, it also includes a fixed housing 17, which adopts a sealed waterproof structure and is made of corrosion-resistant materials to effectively protect the internal electrical components from seawater, moisture, and dust. One end of the fixed housing 17 is bolted to the foot of the dual-head motor 4 to achieve synchronous fixation of the fixed housing 17 and the drive unit. The other end of the fixed housing 17 is bolted to the inner wall of the ring motor rotor 5 to ensure that the fixed housing 17 is firmly installed and moves synchronously with the ring motor rotor 5 and the swing assembly. The fixed housing 17 contains a sealed controller, a gyroscope, and a backup power supply. The controller, the gyroscope, and the backup power supply are electrically connected to each other to form a complete control and power supply system. The gyroscope can detect the attitude of the device in real time. The system detects the gyroscope's position, swing angle, and the ship's turbulence, transmitting the detected signals to the controller in real time. As the core control component, the controller precisely controls the operation of the dual-head motor 4 and the linear motor magnetic rail 14 based on the gyroscope's detection signals and operator instructions, achieving precise adjustment of the swing angle and deployment speed. A high-capacity battery serves as the backup power supply, providing emergency power to the controller, dual-head motor 4, linear motor magnetic rail 14, and other electrical components in the event of a main power failure, ensuring the lifeboat release device functions normally and preventing the lifeboat from failing to launch due to power outages. The controller is electrically connected to the dual-head motor 4, enabling precise control of its start / stop and speed adjustment, thereby controlling the swing angle and speed of the swing assembly.

[0025] Specifically, the delivery assembly includes a support unit and a sliding unit. The support unit is used to support the lifeboat and provides an installation base for the sliding unit. The sliding unit is fitted onto the outer circumference of the support unit and can slide back and forth along the axial direction of the support unit, thereby driving the lifeboat to achieve translation and delivery, ensuring that the lifeboat can quickly and smoothly detach from the hull and fall into the water.

[0026] Specifically, the supporting unit includes a support rail 9, which is made of high-strength aluminum alloy profile, combining the advantages of lightweight and high strength. This allows it to reduce the overall weight of the device while stably supporting the weight of the lifeboat. The lower surface of the support rail 9 is fixedly connected to the linear motor magnetic guide rail 14 by bolts. The linear motor magnetic guide rail 14 is waterproof and serves as the power source for the sliding unit, enabling it to slide smoothly along the axial direction of the support rail 9. The ends of both the support rail 9 and the linear motor magnetic guide rail 14 are fixedly connected to the driven gear 8. The rotation of the driven gear 8 causes the support rail 9 and the linear motor magnetic guide rail 14 to swing synchronously, thereby causing the entire delivery assembly to swing and adjusting the delivery angle.

[0027] Specifically, a guide groove 13 is provided on each of the other three surfaces of the support rail 9 along the axial direction. The guide groove 13 adopts an arc-shaped structure design and the surface is polished to reduce the friction during the sliding process. The size of the guide groove 13 is adapted to the pulley 12 of the sliding unit, which can guide and limit the pulley 12, ensuring that the sliding unit slides smoothly along the axial direction of the support rail 9, avoiding problems such as deviation and shaking during the sliding process, and ensuring the stability of the lifeboat deployment process.

[0028] Specifically, the sliding unit includes four connecting rings 16, which are made of corrosion-resistant alloy material and have sufficient structural strength to stably connect the components. Two connecting rings 16 form a group, and each group of connecting rings 16 is respectively arranged on the support rail 9 and the linear motor magnetic guide rail 14. The two groups of connecting rings 16 are symmetrically arranged to ensure uniform force distribution and to stably drive the bracket 10 and lifeboat to slide. Each connecting ring 16 is rotatably mounted with three pulleys 12 via bearings. The pulleys 12 are made of wear-resistant rubber material with anti-slip texture on the surface. The pulleys 12 are precisely matched with the guide groove 13, allowing the pulleys 12 to roll smoothly within the guide groove 13, reducing the friction between the sliding unit and the support rail 9 and ensuring smooth sliding of the sliding unit. At the same time, the rubber pulleys 12 can act as a buffer, reducing noise and vibration during the sliding process and preventing damage to the lifeboat. The lower end of each set of connecting rings 16 is fixedly connected to both ends of the linear motor slider 15 by bolts. The linear motor slider 15 is adapted to the linear motor magnetic guide rail 14, and the linear motor slider 15 and the linear motor magnetic guide rail 14 are connected by magnetic transmission. This transmission method has the advantages of fast response speed, smooth transmission, and accurate positioning. Under the control of the controller, it can drive the connecting rings 16, brackets 10, and lifeboats to slide quickly and smoothly along the axial direction of the linear motor magnetic guide rail 14 and support rail 9, realizing the lifeboat deployment action; each set of connecting rings 16 The upper ends of 6 are all fixedly connected to the bracket 10 by welding. The bracket 10 adopts a frame structure design, which is adapted to the bottom shape of the lifeboat and can stably support the lifeboat. The bracket 10 is equipped with a fixed support block 11. The fixed support block 11 is made of elastic rubber material, which can buffer and protect the bottom of the lifeboat, and avoid hard contact between the lifeboat and the bracket 10, which would cause damage. At the same time, the fixed support block 11 is in close contact with the lower surface of the lifeboat, which further improves the stability of the lifeboat on the bracket 10 and prevents displacement during swinging and sliding. The lifeboat is fixedly connected to the hull by a rigging system made of high-strength steel wire rope, which has sufficient load-bearing capacity to securely fix the lifeboat to the bracket 10 in a non-escape state, preventing the lifeboat from swaying or falling due to ship pitching. In case of an emergency requiring escape, the operator can unlock the rigging system manually or automatically by the controller, allowing the lifeboat to completely detach from the hull. Subsequently, the controller activates the linear motor magnetic guide rail 14, causing the linear motor slider 15, connecting ring 16, bracket 10, and lifeboat to slide along the support rail 9. At the same time, the swing component adjusts the angle of the delivery component to ensure the lifeboat lands smoothly on the water, completing the lifeboat release operation. The lifeboat is equipped with a deceleration parachute at its stern. After being deployed for a period of time, the deceleration parachute opens to reduce the incident velocity of the lifeboat when it enters the water, thereby reducing the impact on the crew inside the lifeboat.

[0029] Specifically, the linear motor magnetic guide rail 14 is electrically connected to the controller. The controller can precisely control the start and stop, sliding speed and sliding distance of the linear motor magnetic guide rail 14 according to the actual deployment needs, thereby controlling the deployment speed and deployment position of the lifeboat, ensuring that the lifeboat can quickly and safely detach from the hull. At the same time, it can adjust the sliding speed in real time according to the sea state signal detected by the gyroscope to avoid danger during the deployment of the lifeboat due to ocean currents and waves.
