Description

Technical Field

[0001] This invention relates to the field of marine technology, and more specifically, to a device and method for rapidly releasing a lifebuoy by rotation. Background Technology

[0002] According to the SOLAS Convention for the Safety of Life at Sea, lifebuoys equipped with self-illuminating float lights and self-emitting smoke signals must be installed on both sides of the bridge of a ship, and must be able to be quickly thrown from the bridge. Existing lifebuoy release devices, such as the one disclosed in CN 213200055 U, are manually operated remote-controlled lifebuoy release devices. This device includes a lifebuoy release frame, a rotating baffle, several pulleys, a steel wire rope, a bulkhead tube, and a triangular pull ring. The lifebuoy release frame includes guardrails on both sides and a bottom inclined rail. The rotating baffle is located at the bottom of the inclined rail, and the rotating baffle, inclined rail, and guardrails work together to limit the lifebuoy. The rotating baffle is released by the steel wire rope. The steel wire rope's traction direction is changed by multiple pulleys. A bulkhead tube is installed at the bridge bulkhead, through which the steel wire rope passes into the bridge. A pull ring is installed at the end of the steel wire rope for the driver to operate and release the rotating baffle. This invention allows the driver to operate and release the lifebuoy from inside the bridge.

[0003] Existing lifebuoy release devices, while enabling rapid release of lifebuoys from the wheelhouse, have fixed rails that are fixed to the ship's bulkheads. This means that the lifebuoy rolls down in a fixed direction, making it easy for it to fall onto the main deck and become impossible to lower into the water, or to land on the side of the ship that makes it difficult for personnel to spot.

[0004] Therefore, there is an urgent need to develop and design a device and method for rapidly releasing a rotating lifebuoy to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art. One of the objectives of the present invention is to provide a device for rapidly releasing a lifebuoy by rotation, so as to release the lifebuoy onto the water surface.

[0006] The second objective of this invention is to provide a method for rapidly releasing a lifebuoy by rotation, thereby enabling the lifebuoy to be released quickly and accurately onto the water surface.

[0007] To achieve the first objective mentioned above, the present invention provides a device for rapidly releasing a lifebuoy by rotation, comprising a slide on which the lifebuoy is movably placed, the slide being rotatably installed on one side of a ship's bulkhead, and a drive mechanism being provided between the ship's bulkhead and the slide to drive the slide to rotate rapidly so that the lifebuoy is thrown out in a parabolic trajectory.

[0008] As a further improvement, the slide includes an upper limit frame, a lower limit frame, and a connecting plate. The upper limit frame and the lower limit frame are both U-shaped frames with two ends. One end of the upper limit frame and the lower limit frame are respectively installed at the upper and lower ends of the connecting plate. The connecting plate is connected to the ship's bulkhead by multiple hinges. The lifebuoy is movably placed between the upper limit frame and the lower limit frame. The other end of the upper limit frame and the lower limit frame is provided with a limiting structure on the ship's bulkhead to prevent the lifebuoy from falling off. A locking structure is provided between the upper limit frame and the ship's bulkhead to prevent the slide from rotating.

[0009] Furthermore, the locking structure includes two magnetically opposite magnets, one of which is fixed to the ship's bulkhead and the other is fixed to the top of the upper limit frame, with the two magnets attracting and fixing each other together.

[0010] Furthermore, the limiting structure includes a limiting plate, which is fixed to the ship's bulkhead and located on one side of the lifebuoy.

[0011] Furthermore, the upper limit frame and the connecting plate are fixedly connected, and the lower limit frame and the connecting plate are hinged together by a hinge shaft, and a torsion spring is sleeved on the hinge shaft, with the two ends of the torsion spring connected to the connecting plate and the lower limit frame respectively.

[0012] Furthermore, the bottom surface of the lower limit frame is an inclined surface.

[0013] Furthermore, a limiting block is provided on the ship's bulkhead below the lower limiting frame.

[0014] Furthermore, the ship bulkhead is provided with an installation plate, and the connecting plate is connected to the installation plate by multiple hinges. The lower part of the installation plate is provided with a rubber pad, and the position of the rubber pad corresponds to the position of the lower limit frame.

[0015] Furthermore, the drive mechanism includes a pull rope and a pulley. One end of the pull rope is connected to the other end of the upper limit frame, and the other end passes through the pulley and extends into the driver's cab. A guide block is provided on the outer wall of the driver's cab, and the pull rope passes through the guide block. A stop block is provided on the pull rope above the guide block. When the slide is fixed to the ship's bulkhead by magnetic block, the stop block is attached to the top surface of the guide block.

[0016] To achieve the second objective mentioned above, the present invention provides a method for rapidly releasing a lifebuoy by rotation, including the aforementioned device. The method involves rapidly pulling a rope from inside the driver's cab, causing two magnetic blocks to separate under the pulling force, and the slide to rotate rapidly under the pulling force, moving away from the limiting structure. At this time, the lifebuoy slides along the axial direction of the upper and lower limiting frames and detaches from the slide under the action of centrifugal force, and finally is thrown out onto the water surface with a parabolic trajectory.

[0017] Beneficial effects

[0018] Compared with the prior art, the advantages of this invention are as follows:

[0019] The device of this invention places a lifebuoy on a slide that can rotate relative to the ship's bulkhead. When the lifebuoy needs to be released, a drive structure causes the slide to rotate rapidly, causing the lifebuoy to land on the water surface in a parabolic trajectory. Since the lifebuoy is thrown outwards from the ship's bulkhead, it is kept away from the bulkhead, thus avoiding the lifebuoy landing on the main deck. This achieves a fast and accurate release of the lifebuoy onto the water surface, and the location of the lifebuoy can be clearly seen by the personnel on board. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0028] See Figure 1-6 This invention discloses a rotary rapid-release lifebuoy device, comprising a slide 2 on which a lifebuoy 1 is movably placed. The slide 2 is rotatably mounted on one side of a ship's bulkhead 3, allowing it to rotate horizontally relative to the bulkhead 3 and open outwards. A drive mechanism is provided between the bulkhead 3 and the slide 2 to rapidly rotate the slide 2, causing the lifebuoy 1 to be thrown out in a parabolic trajectory. Specifically, the slide 2 includes an upper limit frame 21, a lower limit frame 22, and a connecting plate 23. The upper limit frame 21 and the lower limit frame 22 are both U-shaped frames with two ends, facilitating the lifebuoy 1 to slide out between the ends of the two limit frames. One end of the upper limit frame 21 and the lower limit frame 22 are respectively mounted on the upper and lower ends of the connecting plate 23, forming a U-shaped groove with an open left end (e.g., ...). Figure 5 As shown, when the slide 2 is opened, the lifebuoy 1 can slide out from the opening at the left end. The connecting plate 23 is connected to the ship's bulkhead 3 by multiple hinges, which enables the slide 2 to be rotated and installed. The lifebuoy 1 is movably placed between the upper limit frame 21 and the lower limit frame 22. On the ship's bulkhead 3 corresponding to the other end of the upper limit frame 21 and the lower limit frame 22, there is a limiting structure to prevent the lifebuoy 1 from falling off, thereby limiting the lifebuoy 1 and preventing the lifebuoy 1 from falling off due to the movement of the ship by the waves. There is a locking structure between the upper limit frame 21 and the ship's bulkhead 3 to prevent the slide 2 from rotating, thereby preventing the slide 2 from opening automatically due to the movement of the ship by the waves.

[0029] The device of this invention places a lifebuoy on a slide that can rotate relative to the ship's bulkhead. When the lifebuoy needs to be released, a drive structure causes the slide to rotate rapidly, causing the lifebuoy to land on the water surface in a parabolic trajectory. Since the lifebuoy is thrown outwards from the ship's bulkhead, it is kept away from the bulkhead, thus avoiding the lifebuoy landing on the main deck. This achieves a fast and accurate release of the lifebuoy onto the water surface, and the location of the lifebuoy can be clearly seen by the personnel on board.

[0030] Preferably, the locking structure includes two magnet blocks 4 with opposite magnetic properties. One magnet block 4 is fixed to the ship's bulkhead 3, and the other magnet block 4 is fixed to the top of the upper limit frame 21. The two magnet blocks 4 are attracted to each other and fixed together, which satisfies the need to lock the slide 2 while facilitating the opening of the slide 2.

[0031] Preferably, the limiting structure includes a limiting plate 5, which is fixed to the ship's bulkhead 3 and is located on one side of the lifebuoy 1, thereby limiting the lifebuoy 1.

[0032] Preferably, the upper limit frame 21 is fixedly connected to the connecting plate 23, and the lower limit frame 22 is hinged to the connecting plate 23 via a hinge shaft. A torsion spring 14 is fitted onto the hinge shaft, with both ends of the torsion spring 14 connected to the connecting plate 23 and the lower limit frame 22, respectively. The torque of the torsion spring 14 is equal to the weight of the lifebuoy 1. The lower limit frame 22 is hinged and, in conjunction with the torque of the torsion spring 14, supports the lifebuoy 1. When the slide 2 opens and collides with the rubber pad 8, the lower limit frame 22 vibrates slightly, thus vibrating the lifebuoy 1 and ensuring that the lifebuoy 1 falls.

[0033] Preferably, the bottom surface of the lower limit frame 22 is an inclined surface, such as... Figure 5 As shown, the lower limit frame 22 is an inclined surface with the left end lower and the right end higher, which makes it easier for the lifebuoy 1 to slide down.

[0034] Preferably, a limiting block 6 is provided on the ship bulkhead 3 below the lower limiting frame 22. When the slide 2 is closed, the limiting block 6 can further prevent the lower limiting frame 22 from swinging down.

[0035] Preferably, an mounting plate 7 is provided on the ship bulkhead 3, wherein the connecting plate 23 is connected to the mounting plate 7 by multiple hinges to facilitate the installation of the slide rail 2. A rubber pad 8 is provided at the bottom of the mounting plate 7, and the position of the rubber pad 8 corresponds to the position of the lower limit frame 22. The rubber pad 8 is used to contact and collide with the slide rail 2 to avoid the problem of rigid collision, while also having a certain elasticity.

[0036] Preferably, the drive mechanism includes a pull rope 9 and a pulley 10. One end of the pull rope 9 is connected to the other end of the upper limit frame 21, and the other end passes through the pulley 10 and extends into the cab 11. The end of the pull rope 9 in the cab 11 can be connected to a handle for easy pulling. A frame surrounding the groove of the pulley 10 can be welded onto the bracket of the pulley 10 to prevent the pull rope 9 from detaching from the pulley 10. A guide block 12 is provided on the outer wall of the cab 11, and the pull rope 9 passes through the guide block 12 to guide the pull rope 9. A stop block 13 is provided on the pull rope 9 above the guide block 12. When the slide 2 is attracted and fixed to the ship's bulkhead 3 by the magnet block 4, the stop block 13 fits against the top surface of the guide block 12, so that the pull rope 9 between the guide block 12 and the slide 2 is taut, which facilitates the rapid response and opening of the slide 2 when the pull rope 9 is pulled.

[0037] A method for rapidly releasing a lifebuoy by rotation includes the aforementioned device. The method involves rapidly pulling the rope 9 inside the cab 11, causing the two magnet blocks 4 to separate under the pulling force. The slide 2 rotates rapidly under the pulling force, moving away from the limiting structure. At this time, the lifebuoy 1 slides along the axial direction of the upper limit frame 21 and the lower limit frame 22 under the action of centrifugal force and disengages from the slide, finally being thrown out onto the water surface with a parabolic trajectory.

[0038] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
