The utility model enables the driver to operate and release the lifebuoy in the cab.
[0003] Although the existing lifebuoy releasing device can realize the quick release of the lifebuoy in the cab, its inclined rail is fixedly connected to the bulkhead of the ship, that is, when the lifebuoy rolls down, its direction is fixed. In actual use, the lifebuoy is easy to fall onto the main deck, resulting in the problem that it cannot be lowered into the water, or it falls on the water surface close to one side of the ship, which makes it difficult for personnel to observe the position of the lifebuoy.
[0004] Therefore, it is urgent to develop and design a device and method for rotating quick-release lifebuoy to solve the above problems. Summary of the invention

[0010] Furthermore, the limiting structure comprises a limiting plate, the limiting plate is fixed on the bulkhead of the ship, and the limiting plate is located on one side of the lifebuoy.
[0011] Furthermore, the upper limit frame and the connecting plate are fixedly connected, the lower limit frame and the connecting plate are hingedly connected via a hinge shaft, and a torsion spring is sleeved on the hinge shaft, and both ends of the torsion spring are respectively connected to the connecting plate and the lower limit frame.

The method is to quickly pull the pull rope in the cab, the two magnet blocks are separated under the action of the tension, and the slide quickly rotates under the action of the tension and moves away from the limiting structure; at this time, the life buoy slides along the axial direction of the upper limit frame and the lower limit frame under the action of centrifugal force and separates from the slide, and finally is thrown onto the water surface with a parabolic trajectory.

DETAILED DESCRIPTION
[0027] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0028] See also Figure 1-6 The present invention discloses a device for quickly releasing a lifebuoy by rotating it, comprising a slide 2 on which a lifebuoy 1 is movably placed, and the slide 2 is rotatably mounted on one side of a ship's bulkhead 3, so that the slide 2 can rotate horizontally relative to the ship's bulkhead 3 and open to the outside of the ship's bulkhead 3, and a driving mechanism is provided between the ship's bulkhead 3 and the slide 2 to drive the slide 2 to rotate rapidly so that the lifebuoy 1 is thrown out in a parabolic trajectory. Specifically, the slide 2 comprises an upper limit frame 21, a lower limit frame 22 and a connecting plate 23, wherein the upper limit frame 21 and the lower limit frame 22 are both U-shaped frames with two ends, so that the lifebuoy 1 can slide out from between the ends of the two limit frames, and 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 (such as Figure 5 As shown in the figure, when the slide 2 is opened, the lifebuoy 1 can slide out from the opening at the left end, and the connecting plate 23 is connected to the ship bulkhead 3 by a plurality of hinges to realize the rotation installation of the slide 2, and the lifebuoy 1 is movably placed between the upper limit frame 21 and the lower limit frame 22, and a limiting structure for preventing the lifebuoy 1 from falling off is provided on the ship bulkhead 3 corresponding to the other end of the upper limit frame 21 and the lower limit frame 22, so as to limit the lifebuoy 1 and prevent the lifebuoy 1 from falling off due to the fluctuation of the ship by the sea waves, and a locking structure for preventing the slide 2 from rotating is provided between the upper limit frame 21 and the ship bulkhead 3 to prevent the slide 2 from opening automatically due to the fluctuation of the ship by the sea waves.
[0029] The device of the present invention places a lifebuoy on a slideway that can rotate relative to the ship's bulkhead. When the lifebuoy needs to be released, the driving structure drives the slideway to rotate rapidly, so that the lifebuoy falls on the water surface in a parabolic trajectory, thereby releasing the lifebuoy on the water surface. Since the lifebuoy is thrown outward from the ship's bulkhead, the lifebuoy is away from the ship's bulkhead, thus preventing the lifebuoy from falling on the main deck, thereby quickly and accurately releasing the lifebuoy on the water surface, and the personnel on the ship can intuitively see the location of the lifebuoy.
[0030] Preferably, the locking structure includes two magnet blocks 4 with opposite magnetic properties, one magnet block 4 is fixed to the ship 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 adsorbed and fixed together, which can lock the slide 2 while facilitating the opening of the slide 2.
[0031] Preferably, the limiting structure comprises a limiting plate 5 , which is fixed on the ship bulkhead 3 , and the limiting plate 5 is located on one side of the lifebuoy 1 , so as to limit the lifebuoy 1 .
[0032] Preferably, the upper limit frame 21 is fixedly connected to the connecting plate 23, the lower limit frame 22 is hingedly connected to the connecting plate 23 through a hinge shaft, and a torsion spring 14 is sleeved on the hinge shaft, and the two ends of the torsion spring 14 are respectively connected to the connecting plate 23 and the lower limit frame 22, and the torsion of the torsion spring 14 is equal to the gravity of the life buoy 1. The lower limit frame 22 is hingedly installed and supports the life buoy 1 with the torsion of the torsion spring 14. When the slide 2 is opened and collides with the rubber pad 8, the lower limit frame 22 can swing slightly due to the vibration, which can play a role in vibrating the life buoy 1 and ensure that the life buoy 1 can fall.
[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 a lower left end and a higher right end, which is more conducive to the sliding of the lifebuoy 1.
[0034] Preferably, a limit block 6 is provided on the ship bulkhead 3 below the lower limit frame 22. When the slideway 2 is closed, the limit block 6 can further prevent the lower limit frame 22 from swinging downward.
[0035] Preferably, a mounting plate 7 is provided on the ship bulkhead 3, wherein a connecting plate 23 is connected to the mounting plate 7 by a plurality of hinges, so as to facilitate the installation of the slide 2. A rubber pad 8 is provided at the lower portion 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 2 to avoid the problem of rigid collision, and at the same time has a certain elastic effect.
[0036] Preferably, the driving mechanism includes a pull rope 9 and a pulley 10, wherein 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 to facilitate pulling the pull rope 9. A frame surrounding the slide groove of the pulley 10 can be welded on the bracket of the pulley 10 to avoid the problem of the pull rope 9 detaching from the pulley 10. A guide block 12 is provided on the outer wall of the cab 11. The pull rope 9 is passed through the guide block 12 to guide the pull rope 9, and a stop block 13 is provided on the pull rope 9 above the guide block 12. When the slide 2 is adsorbed and fixed on the ship bulkhead 3 by the magnet block 4, the stop block 13 is attached to the top surface of the guide block 12, so that the pull rope 9 between the guide block 12 and the slide 2 is in a straightened state, which is convenient for pulling the pull rope 9 and can quickly respond to the linkage slide 2 to rotate and open.
[0037] A method for quickly releasing a life buoy by rotation includes the above-mentioned device. The method is as follows: a pull rope 9 is quickly pulled in a cab 11, and the two magnet blocks 4 are separated under the action of the pulling force, and the slide 2 is quickly rotated under the action of the pulling force and moves away from the limiting structure; at this time, the life buoy 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 separates from the slide, and is finally thrown onto the water surface with a parabolic trajectory.
[0038] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
