The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

During the construction of a ship, a life raft release system is an essential part, and the life raft release system mainly releases the life raft to the outside (water surface) of the ship so as to facilitate quick escape and evacuation of people on the ship in an emergency.

As shown in fig. 1, the present embodiment discloses a release system for a liferaft, which comprises a release frame, a liferaft 30 and a release mechanism, wherein the release frame comprises a frame 1 and a connecting rod 2, and one end of the connecting rod 2 is fixedly arranged on the frame 1. The release mechanism of this embodiment includes a release member 4 and a strap 5, the release member 4 being selectively connectable to the strap 5. When the release element 4 is connected to the straps 5, the release element 4 is able to strap the liferaft 30 to the links 2 via the straps 5. When the liferaft 30 is released, the release part 4 is disconnected from the binding band 5, the liferaft 30 is separated from the binding band 5 and rolls down to the outside of the ship along the connecting rod 2, and the liferaft 30 is released smoothly.

At present, in the ship building process, the release bracket needs to be installed on the deck 10 near the inner side of the bulwark, so that the appearance of the ship is more neat and beautiful to meet the design requirements of the ship. Meanwhile, the installation height of the release frame on the deck 10 cannot be too high, so that the stability of the lifesaving equipment is prevented from being reduced. The normal use of the liferaft release system is affected because the ship's bulwarks easily prevent the successful release of the liferaft 30.

To solve the above problem the liferaft release system further comprises a bulwark with a movable wall 20 hingedly connected to the deck 10. The movable wall 20 has a tendency to turn toward the outside of the bulwark. When the movable wall 20 is not disturbed by an external force, it can be turned over toward the outside of the bulwark to open the notch on the bulwark for abdicating the life raft 30, so that the life raft 30 can be smoothly released.

Specifically, the bracket 1 is located inside the bulwark, and is disposed opposite to the movable wall body 20. The tie rods 2 extend obliquely downward in a direction toward the corresponding bulwark. When the release element 4 is connected to the straps 5, the liferaft 30 is fastened to the links 2 by the straps 5 and the movable wall 20 is tightened by the straps 5 to avoid the movable wall 20 turning over towards the outside of the bulwark, which could damage the integrity of the bulwark. When the release member 4 is disconnected from the strap 5, the movable wall 20 and the liferaft 30 can be released simultaneously, so that the movable wall 20 is turned over towards the outer side of the bulwark, and the liferaft 30 rolls along the connecting rod 2 extending obliquely downwards simultaneously under the action of the gravity of the liferaft 30 and rolls down to the outer part of the bulwark through the corresponding notch of the movable wall 20 on the bulwark.

The life raft release system of the embodiment can synchronously release the movable wall 20 and the life raft 30, so that smooth release of the bulwark blocking the life raft 30 is avoided, passengers or crews can evacuate quickly, and the reliability and stability of the life raft release system are improved.

It should be noted that the release mechanism of the present embodiment is a purchased part, which reduces the design cost and the production period of the release system of the liferaft and is beneficial to reduce the cost.

In particular, the release mechanism may be an electric release device and automatically controls the release member 4 to automatically tighten or loosen the strap 5 via a control system in the cabin of the vessel. It is not necessary to arrange personnel to manually operate the release member 4 on the deck 10 when the liferaft 30 is released, which reduces the number of personnel required to be equipped for the liferaft release system, improves the automation of the liferaft release system, and is beneficial to reducing the operation cost of the ship.

The release member 4 and the strap 5 of the present embodiment are disconnected from each other by cutting the strap 5. Of course, the disconnection between the release element 4 and the strap 5 can also be achieved by means of unhooking. As the electric release device is a mature product, the specific structure and the working process are not described in detail.

As shown in fig. 1, the stand 1 includes a first upright 11 and a second upright 12. The second upright 12 is located between the first upright 11 and the corresponding bulwark, and the first upright 11 is higher than the second upright 12. One end of the connecting rod 2 is fixedly arranged on the first upright post 11, and the other end of the connecting rod 2 is arranged at the top end of the second upright post 12, so that the connecting rod 2 extends downwards towards the corresponding bulwark in an inclined manner, and the life raft 30 can roll down along the connecting rod 2 to be released.

Specifically, one end of the connecting rod 2 is fixedly connected to the middle position of the first upright 11, and a part close to the other end is arranged at the top end of the second upright 12, so that the bracket 1 is approximately in an h-shaped structure.

In order to ensure the fixing effect of the straps 5 on the life raft 30 and the tensioning effect on the movable wall 20, the bracket 1 further comprises the tensioning columns 13, the tensioning columns 13 are arranged on the first upright post 11 at intervals along the height direction of the first upright post 11, and the straps 5 are wound on the tensioning columns 13, so that the straps 5 can be always kept in a tensioned state before the life raft 30 is released, and the tension for fixing the life raft 30 and tensioning the movable wall 20 is kept stable.

Specifically, the number of the tensioning columns 13 in this embodiment is two, and the two tensioning columns 13 are disposed on the side wall of the first upright 11 in an up-down opposite manner. The release element 4 is located between two tension columns 13, one end of the straps 5 passing around one tension column 13 and securing the liferaft 30 to the link 2, and the other end of the straps 5 passing around the other tension column 13 and tightening the movable wall 20.

As shown in fig. 1 and 2, the liferaft release system further comprises a base 8, the base 8 being arranged with its lower end on the deck 10, and the bracket 1 being detachably mounted on the upper end of the base 8. The support 1 is fixedly arranged on the deck 10 through the base 8, and the installation efficiency of the base 8 is improved.

The base 8 of this embodiment is fixedly mounted on the deck 10 by welding, so that the connection strength between the base 8 and the deck 10 is high, the stability of the support 1 is improved, and the life raft 30 is prevented from shaking excessively in the releasing process.

First stand 11 all installs in the top of base 8 through bolt detachably with second stand 12, adopts the bolted connection mode for joint strength is high, and stability is good. Meanwhile, different types of supports 1 can be replaced quickly to adapt to different types of life rafts 30, and the supports 1 can be replaced flexibly.

Preferably, the height of the base 8 of the present embodiment is adjustable to adjust the height of the support frame 1, so that the placement height of the life raft 30 can be adaptively adjusted according to the heights of different bulwarks, and the life raft 30 can roll down to the water surface through the bulwarks. By flexibly adjusting the height of the base 8 the versatility of the liferaft release system is improved.

Specifically, base 8 includes platform and a plurality of automatic lifting rod, and a plurality of lifting rods distribute in deck 10 upper bracket 1's installation region, the bottom and the deck 10 welded fastening of lifting rod, the top support of lifting rod is connected with the platform, and first stand 11 passes through bolt fixed mounting on the platform with second stand 12. It will be appreciated that the extension or retraction of the lifting rods may be driven by a hydraulic, pneumatic or electric motor or the like to adjust the height of the platform.

As shown in fig. 1 and 2, the release system of the liferaft further comprises a rocker 3, one end of the rocker 3 is hinged to the end of the connecting rod 2 remote from the bracket 1, and a strap 5 is connected to the other end of the rocker 3.

In particular, the rocker 3 has a first position and a second position, the rocker 3 being in the first position when the release element 4 is connected to the strap 5 and the rocker 3 is tightened by the strap 5, the rocker 3, the bracket 1 and the connecting rod 2 together clasping the liferaft 30. As shown in fig. 1, the first upright post 11, the connecting rod 2 and the rocker 3 in the first position together enclose a cavity for accommodating the liferaft 30, and the straps 5 fix the liferaft 30 in the cavity, which improves the stability of the liferaft 30.

When the release element 4 is disconnected from the straps 5, the straps 5 release the rocker 3 and the liferaft 30 rolls down the link 2 and pushes the rocker 3 to rotate to the second position, so that the rocker 3 is connected to the link 2 in an obliquely extending slide. The liferaft 30 rolls down the outside of the bulwark through the slide way. The rocker 3 increases the length of the slide way, improves the rolling distance and speed of the life raft 30, accelerates the release efficiency of the life raft 30, and can ensure the smooth release of the life raft 30.

When the rocker 3 is in the second position, as shown in fig. 2, the ramp is arranged in a straight line obliquely downwards in the direction of extension of the link 2, the end of the ramp being located outside the bulwark so that the liferaft 30 can roll along the ramp and fall to the surface.

It should be noted that, as shown in fig. 1, when the rocker 3 is located at the first position, the height of the top end of the rocker 3 is greater than that of the top end of the movable wall 20. When the release member 4 is disconnected from the strap 5, the rocker 3 is released in synchronism with the movable wall 20. When the turning speed of the movable wall 20 is slow, the rocker 3 rotating from the first position to the second position can press the movable wall 20 to accelerate the turning speed of the movable wall 20. Moreover, the situation that the rocking bars 3 are clamped at the inner side of the movable wall 20 when the top ends of the rocking bars 3 are lower than the movable wall 20 can be avoided, and the life raft 30 can be smoothly released.
