Description

Technical Field

[0001] The invention relates to a lifeboat, in particular to a lifeboat which can be quickly deployed. Background Art

[0002] A lifeboat is a special lifeboat installed on a ship for rescuing passengers in the event of a shipwreck. It is propelled by oars, sails, power engines, etc. Existing lifeboats are usually hung on the side of the main ship with slings. When an emergency occurs, the crew needs to operate the sling system to lower the lifeboat into the water. However, in order to achieve a smooth release of the lifeboat, the existing sling system often has a slow release speed, and after the lifeboat enters the water, the crew must operate to separate the lifeboat from the sling, further reducing efficiency. In the event of an emergency, time is life. The sooner the lifeboat is smoothly placed in the water, the sooner the crew can escape from danger or rescue those in danger.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This solution sets a droop damping system on the suspension so that the rapidly falling lifeboat can achieve nonlinear orderly deceleration when approaching the water surface, thereby ensuring that the impact of the lifeboat will not be too great when it lands on the water surface. That is, this solution not only realizes the rapid deployment of the lifeboat, but also ensures the stability of the lifeboat landing on the water surface after deployment.

[0022] 2. By providing a second telescopic cylinder and a guide rod capable of driving the telescopic rod of the second telescopic cylinder to rotate, the metal plate can be stored in the hull when not in use, thereby preventing the metal plate from being bent by the impact of seawater during the lifeboat formation process.

[0023] 3.

[0024] 4. The purpose of setting the horizontal telescopic cylinder is that the hull will inevitably be bumpy due to the violent ups and downs of the water surface. At this time, the lifeboat is usually made of plastic and is easily deformed, which in turn impacts the guide rail. At this time, if the guide rail is moved away from the hull by the horizontal telescopic cylinder, the impact of the hull on the guide rail can be effectively avoided. In addition, the use of setting the horizontal telescopic cylinder is that when the metal plate is extended again, the guide rail can be driven to make room, and after the metal plate is extended to the right position, the horizontal telescopic cylinder is retracted to allow the metal plate to be conveniently extended into the first guide groove.

[0025] 5. The guide rod group in this solution is formed into a guide rod group with a retractable length through an outer tube and an inner tube, so as to better adapt to the requirements of lifeboat deployment at different draft depths of the main ship.

[0026] 6. The suspension system of this solution realizes the locking and releasing operation between the tenon sleeve and the tenon through the rotation of the eccentric shaft, making the deployment of the lifeboat easier.

[0027] 7. A deviation correction rod is provided to better adjust the position of the retrieved lifeboat, so as to facilitate the subsequent metal plate to enter the first guide groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present invention will be described clearly and completely below 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 creative work are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] like Figures 1 to 12 The lifeboat capable of being quickly deployed comprises a set of suspensions 1 fixedly installed at the side of a main ship, the front end of the suspension (horizontal cantilever part) extending outwards to the outside of the main ship.

[0045] At the same time, a suspension system 3 is installed on the cantilever of the suspension, and a hull 2 ​​for rescue operations is suspended on the suspension system. It should be noted that the suspension system can be self-decoupled from the hull, so that the hull can be quickly separated from the suspension system and fall onto the water surface when performing rescue operations.

[0046] In addition, it should be noted that a set of vertical drop damping systems 4 are also provided on the suspension, and the vertical drop damping system applies a nonlinear damping effect to the free-falling hull, so that the hull 2 ​​can fall into the water smoothly. It should be noted that the nonlinear damping effect in this scheme is proportional to the falling speed of the hull, that is, the faster the falling speed of the hull, the greater the damping strength, so that the falling speed of the hull can be kept within a reasonable range, avoiding excessive impact on the personnel in the hull when the hull falls into the water.

[0047] Specifically, the droop damping system 4 in this solution includes a first telescopic cylinder 41 vertically arranged on the outer end of the suspension 1, and at least one guide rail 42 is fixedly connected to the telescopic rod of the first telescopic cylinder. Figure 2As shown, the guide rail extends vertically along the direction of the free fall of the hull, and two permanent magnets 43 are fixedly installed on the guide rail, with a gap between the two permanent magnets to form a first guide groove 431 extending in the same direction as the extension direction of the permanent magnets. At the same time, a group of guide rod components 44 are fixedly installed on the side wall of the main ship, and a slip ring 45 is slidably sleeved on the guide component 44. The slip ring is fixedly connected to the hull to guide the hull when the hull 1 is freely falling, ensuring that the hull will not shake due to the blowing of the crosswind during the falling, that is, ensuring the stability of the posture of the hull when it falls. It should be noted that a metal plate 46 is also installed on the side of the hull, and the metal plate extends into the first guide groove 431 formed by the two permanent magnets. When the hull is freely descending, the metal plate cuts the magnetic field between the two permanent magnets to form an induced current (eddy current), and the magnetic field formed by the induced current and the permanent magnet will generate a force, and the direction of the force is opposite to the movement direction of the metal plate, that is, an upward thrust (damping effect) is generated on the hull. It should be noted that the magnitude of the damping force generated in this scheme is proportional to the magnitude of the induced current generated in the metal plate, and the magnitude of the induced current is proportional to the descent speed of the hull. Therefore, the faster the hull descends, the stronger the deceleration and braking effect is, so that it can effectively ensure that the hull can fall on the water surface within a safe range without causing a large impact on the personnel in the hull.

[0048] It should be noted that in the above scheme, the metal plate 46 arranged on the side of the hull 1 is in a vertical state. When the lifeboat travels on the water at a high speed, the water flow will inevitably impact the metal plate. This impact will inevitably cause the metal plate to bend after years of accumulation, thereby affecting the normal movement of the metal plate in the first guide groove 431 when the hull is lowered. In order to avoid the above situation, a horizontally extending storage groove 21 is also provided on the side of the hull 1, and a second telescopic cylinder 47 is installed in the storage groove. The metal plate is fixed to the end of the telescopic rod of the second telescopic cylinder to store the metal plate in the storage groove 21 when the second telescopic cylinder retracts. It should be noted that in this scheme, the extended state of the metal plate is vertical and the stored state is horizontal, so as to maximize the area of ​​the metal plate that effectively generates induced current. For this reason, it is necessary to consider the problem of the posture conversion of the metal plate during the recovery process. For this reason, in this scheme, a second guide groove 471 is provided on the telescopic rod of the second telescopic cylinder to guide the telescopic rod to rotate during the extension process. Specifically, the second guide groove includes a first guide section 471a and a second guide section 471b connected in sequence from the outer end to the inner end of the telescopic rod. The first guide section extends along the axial direction of the telescopic rod, while the second guide section is a spiral arrangement of 90° around the outer surface of the telescopic rod. At the same time, a guide rod 410 is also installed in the storage groove 21 of the hull, and the end of the guide rod smoothly extends into the second guide groove. When the telescopic rod is extended under the drive of the second telescopic cylinder, the telescopic rod also performs the following extension actions under the guidance of the guide rod: 1. Axial extension → 2. Axial extension / 90° rotation and parallel extension. Under this extension action, the metal plate can easily extend from the storage groove and rotate from horizontal to vertical. When the metal plate needs to be recovered, the reverse operation can be achieved by simply retracting the second telescopic cylinder.

[0049] It should also be noted that in this solution, the second telescopic cylinder is used to enable the metal plate to be stored in the storage groove, which can also reduce the exposure of the metal plate to the outside and reduce its exposure to wind and rain, that is, it can also provide a certain degree of protection for the metal plate.

[0050] In addition, it should be noted that the life-saving ladder usually travels at a fast speed on the water surface, and a large amount of waves are often generated during its operation. In order to reduce the splashing onto the surface of the metal plate, that is, to slow down the speed at which the metal plate is corroded by water as much as possible, the present solution further provides a sealing rubber plate 48 on the outer surface of the storage groove 21. The sealing rubber plate has a groove in the middle to enable the metal plate to enter and exit. After the metal plate completely enters the storage groove, the groove of the sealing plate automatically restores the seal to reduce the water entering the storage groove and reduce the contact and corrosion of the metal plate by water.

[0051] In addition, after the lifeboat completes the rescue mission, the hull 1 needs to be recovered. At this time, the hull needs to be driven under the suspension 1, and then the suspension system on the suspension is used to lift the hull again. However, in the process of lifting the hull, the hull will not shake even if it is constrained by the guide rod assembly. However, the environment on the water surface is complex. In windy and rainy weather, the main ship itself shakes severely, and the hull 2 ​​fixed at the side of the main ship will inevitably shake greatly. During this shaking process, the hull made of plastic or thin steel plate will inevitably deform to a certain extent, and the deformation of the hull will inevitably impact the guide rails and permanent magnets that have high verticality requirements, causing the guide rails or permanent magnets to tilt, which is not conducive to the smooth fall of the subsequent hull. For this reason, a horizontal telescopic cylinder 49 capable of horizontal extension and contraction is also installed on the suspension 1 of the present scheme, and a first telescopic cylinder 41 is installed on the end of the telescopic rod of the horizontal telescopic cylinder. At this time, the horizontal telescopic cylinder can be driven to extend to drive the guide rail and the permanent magnet connected to the first telescopic cylinder away from the hull to avoid collision between the hull and the guide rail and the permanent magnet. In addition, it should be noted that, through the above-mentioned setting, the metal plate stored in the hull needs to extend and extend into the first guide groove in the present scheme. When preparing for the launch of the hull, the guide rail and the permanent magnet can also be driven to avoid by the horizontal telescopic cylinder to make room for the rapid extension and expansion of the metal plate. When the metal plate is extended to the right position (in a vertical state), the horizontal telescopic cylinder is retracted to drive the guide rail and the permanent magnet to return to their positions, so that the metal plate can be conveniently entered into the first guide groove. It should be noted that under this operation, the posture requirements for the recovery of the hull can also be relatively reduced, which greatly facilitates the recovery of the hull.

[0052] It should also be noted that in this solution, the core component that constrains the hull's vertical lowering posture and recovery posture is the guide rod assembly 44. Specifically, the guide rod assembly in this solution includes an outer tube 441 and an inner rod 442. Among them, the outer tube extends vertically and is fixed on the suspension. The inner rod is slidably inserted into the outer tube. At the same time, the slip ring 45 fixed on the hull is sleeved on the outer tube so that the slip ring can slide on the outer tube when the hull is lowered to constrain the hull.

[0053] It should be noted that the reason why the guide rod assembly 44 in this solution adopts the structure of the extension length of the outer tube and the inner rod is that the main ship equipped with the lifeboat is usually a large ship, and its hull height is relatively high, and the inertia is relatively large when docking. In order to avoid the guide rod assembly from being damaged when docking, and at the same time to ensure that the hull is guided and restrained before falling into the water, it is necessary to use this kind of structure that can be extended when in use and retracted when not in use. In order to ensure that the extended inner rod can also slide with the slip ring, in this solution, at least three slide grooves 441a are provided on the outer tube, and a guide strip 442a matching the number of the slide grooves is provided on the inner rod. The guide strip is slid in the slide groove, and the outer surface of the guide strip is smoothly abutted against the inner surface of the slip ring, so as to ensure the stability of the slip ring when sliding on the inner rod by the principle of determining a surface through three points. In addition, it should be noted that the power component for controlling the extension and retraction of the guide rod assembly 44 includes a first motor 443 fixedly mounted on the side of the ship's side, and a first gear 444 is coaxially connected to the output shaft of the first motor. At the same time, a rack 442b extending along the axial direction of the inner rod is provided on the surface of the inner rod 442, and the rack can be axially slid out of the outer tube and meshed with the first gear. When the inner rod needs to be driven to extend and retract axially, it is only necessary to drive the first motor forward and reverse. In addition, it should be noted that in this solution, in order to ensure that the slip ring does not rotate relative to the outer tube and the inner rod, the slip ring is a non-circular structure, and the outer tube and the inner rod are adapted to the slip ring.

[0054] In addition, it should be noted that, in order to facilitate the insertion of the inner rod into the slip ring when the hull is recovered, the lower end of the inner rod is in the shape of a cone that gradually decreases from top to bottom.

[0055] like Figure 4 As shown, the suspension system 3 in this solution specifically includes four tenons 31 arranged in a matrix on the hull, a tenon sleeve 32 that can be mounted on the tenon, and a winding assembly 33 that can vertically pull the tenon. It should be noted that in order to achieve rapid connection and unhooking operations between the tenon sleeve and the tenon, a circumferential groove 311 is opened on the outer surface of the tenon in this solution. At the same time, two eccentric shafts 34 can be rotatably inserted in the tenon sleeve. The two eccentric shafts are perpendicular to the axis of the tenon sleeve and are located at the edge of the tenon sleeve. This ensures that after the eccentric shaft rotates a certain angle, its eccentric part can enter or move out of the groove. As shown Figure 8 , Fig. 9As shown, in this scheme, in order to realize the automatic implementation of the mortise and tenon engagement and uncoupling actions, so as to facilitate the operation when the hull is lowered, a second gear 35 is coaxially connected to the end of the eccentric shaft, and a second motor 36 is installed on the mortise. A third gear 37 is coaxially connected to the output shaft of the second motor, and the third gear is meshed with the two second gears. When the second motor drives the second gear to rotate, the second gear simultaneously drives the eccentric shaft connected to the third gear to rotate, and the eccentric part of the eccentric shaft will synchronously enter the slot or move out of the slot to realize the engagement or uncoupling operation of the tenon and the mortise. It should be noted that in this scheme, a battery 38 is also fixedly installed on the outside of the mortise to provide electrical energy for the action of the second motor.

[0056] In addition, the winding mechanism 33 in this solution includes two third motors 331 installed on the suspension 1, and the two third motors are symmetrically arranged. At the same time, a winding disk 332 is coaxially installed on the output shaft of the third motor, and the winding disk is symmetrically arranged with two winding areas, so that the two traction ropes 333 can be wound symmetrically when the winding disk rotates. It should be noted that the use of this winding method can not only reduce the number of third motors used, but also effectively improve the synchronization when the hull on the same side is lifted. It should be noted that in this solution, one end of the traction rope wound on the winding disk is connected to the mortise sleeve.

[0057] Finally, it should be noted that in this solution, in order to further improve the accuracy of the posture of the hull when it is in a suspended state, a third telescopic cylinder 5 is also installed on the suspension 1, and a correction rod 6 is coaxially connected to the third telescopic cylinder, and a cross slot 61 is provided at the lower end of the correction rod. At the same time, an adaptive positioning hole 22 is provided on the hull, and a guide spline 23 adapted to the cross slot is provided in the positioning hole. When the correction rod is inserted into the positioning hole, the guide spline enters the cross slot to correct the hull with a certain eccentricity.

[0058] Working principle: When a rescue mission is required, the staff first starts the first motor in the guide rod assembly to rotate, and the rotation of the first motor drives the inner rod to extend downward to 1~2m above the water surface (to ensure that the slip ring is disconnected from the inner rod when the hull falls on the water surface). During the extension of the inner rod, the staff enters the hull synchronously. When the inner rod reaches the right position, the staff immediately controls the second motor to rotate. As the second motor rotates, the eccentric shaft moves out of the slot, and the four tenons are unhooked from the tenons on the hull. The hull then falls vertically. During the hull's fall, the first telescopic cylinder also extends downward rapidly with the falling hull. During this process, the guide rail is kept close to the hull's descending speed so that the metal plate is always in the upper part of the first guide groove. When the lower edge of the guide rail drops to 1~2m from the water surface under the drive of the first telescopic cylinder, the first telescopic cylinder stops moving. At this time, the hull with an extremely high descent speed after free fall acceleration drives the metal plate to cut the magnetic field of the permanent magnet at high speed. Due to the electromagnetic induction, a corresponding induced current is generated in the metal plate according to the descent speed of the hull. The magnetic field formed by the induced current acts together with the magnetic field of the permanent magnet to produce a very intuitive nonlinear damping effect. The speed of the hull is quickly and steadily reduced, so that when the metal plate leaves the first guide rail, the speed of the hull can be reduced to an appropriate range, and the hull can land steadily on the water.

[0059] When the rescue mission is completed and the hull needs to be recovered, the hull can be driven under the suspension, and then the suspension system can be lowered to lock the tenon sleeve with the tenon and start the suspension system. After the hull is lifted to a certain height above the water surface, the crew in the hull inserts the lower end of the auxiliary inner rod into the slip ring, and then continues to lift the hull to the initial stage through the suspension system. After the above steps are completed, the third telescopic cylinder is driven to extend so that the correction rod is inserted into the positioning hole. After being guided by the guide spline in the positioning hole, the hull reaches a position where it can be directly launched next time, so as to prepare for the next rapid launch.
