Description

Technical Field

[0001] The invention belongs to the field of ship construction and design, and in particular relates to a device for preventing a life raft from accidentally falling off a ship. Background Art

[0002] A life raft is a life-saving device equipped on a ship for escaping from a dangerous area or for emergency evacuation of a distressed ship in an emergency. The life raft is usually stored in a fiberglass storage tube and installed on a special raft frame. In an emergency, the life raft can be thrown directly into the water, and the life raft can be automatically inflated and formed for people in distress to ride; if the ship sinks too fast and there is no time to throw the life raft into the water, when the ship sinks to a certain depth underwater, the hydrostatic pressure releaser on the raft frame will automatically unhook and release the life raft, which will float to the surface and automatically inflate and form.

[0003] During normal navigation, the life raft is fixed to the side of the ship by lashing devices. However, the lashing devices are easily aged due to being outdoors. Once the lashing devices of the old-fashioned life raft racks are aged, the life raft will easily slide off if the crew does not find it. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a device for preventing a life raft from accidentally falling. The technical solution adopted is:

[0005] A device for preventing a life raft from accidentally falling on a ship comprises a frame-type base, a support surface is formed on the frame-type base, the support surface is arranged to be inclined downward, the life raft is placed on the support surface, a support rod extends upward on the higher side of the support surface, a cross brace is fixed between the two support rods, a rocker arm is arranged on the lower side of the support surface, the rocker arm is hinged to the support surface, the rocker arm can be arranged upright relative to the support surface, and can also be located on the same plane as the support surface.

[0006] A connecting rod is hinged on the rocker arm, a strip pull rod passes through a cross brace to connect with the connecting rod, an end of the connecting rod is a hook arranged in a bent manner, the end of the pull rod is provided with a round hole, and the hook at the end of the connecting rod passes through the round hole and is hooked with the pull rod.

[0007] A hydrostatic pressure releaser is fixed in the middle of the cross brace, and the rope loop of the hydrostatic pressure releaser is connected to one end of the lashing rope. After the lashing rope wraps around the life raft for one circle, the other end is fixed to the hook at the end of the connecting rod.

[0008] The above-mentioned device for preventing a life raft from accidentally falling on a ship, further, has the cross brace located below the supporting surface.

[0009] The above-mentioned device for preventing a life raft from accidentally falling on a ship, further, has a winding column arranged on the top of the support rod, and the lashing rope is wound around the winding column and then winds around the life raft.

[0010] The above-mentioned device for preventing a life raft from accidentally falling on a ship, further, comprises two lashing ropes which are symmetrically wound around two sides of the life raft.

[0011] The above-mentioned device for preventing a life raft from accidentally falling on a ship, further, is provided with a fixing plate on the pull rod, and the fixing plate is located outside the frame.

[0012] The above-mentioned ship-used device for preventing life rafts from accidentally falling, further, is provided with a locking plate on the cross brace, the locking plate is located on the outside of the frame, one end of the locking plate can rotate around the axis on the cross brace, and the other end of the locking plate has a notch, which is stuck on the pull rod. When locked, the fixed plate is located between the locking plate and the cross brace.

[0013] The utility model has the advantages of simple structure, convenient and reliable use, and realizes the functions by making only a small modification on the basis of the original raft frame, and the original raft frame can be automatically released and the life raft can be thrown.

[0020] The present invention will be further described in conjunction with the accompanying drawings.

[0021] A device for preventing a life raft from accidentally falling on a ship comprises a frame-type base, a support surface is formed on the frame-type base, the support surface is arranged to be inclined downward, the life raft is placed on the support surface, a support rod extends upward on the higher side of the support surface, a cross brace is fixed between the two support rods, a rocker arm is arranged on the lower side of the support surface, the rocker arm is hinged to the support surface, the rocker arm can be arranged upright relative to the support surface, and can also be located on the same plane as the support surface.

[0022] A connecting rod is hinged on the rocker arm, a strip pull rod passes through a cross brace to connect with the connecting rod, an end of the connecting rod is a hook arranged in a bent manner, the end of the pull rod is provided with a round hole, and the hook at the end of the connecting rod passes through the round hole and is hooked with the pull rod.

[0023] A hydrostatic pressure releaser is fixed in the middle of the cross brace, and the rope loop of the hydrostatic pressure releaser is connected to one end of the lashing rope. After the lashing rope wraps around the life raft for one circle, the other end is fixed to the hook at the end of the connecting rod.

[0024] A locking plate is provided on the cross brace, the locking plate is located outside the frame, one end of the locking plate can rotate around the axis on the cross brace, the other end of the locking plate has a notch, the notch is stuck on the pull rod, when locked, the fixed plate is located between the locking plate and the cross brace.

[0025] There are two working modes, one is the automatic release state, such as Figure 3 As shown, the ship sinks too fast and there is no time to throw the life raft into the water. When the ship sinks to a certain depth underwater, the hydrostatic pressure releaser on the raft frame 1 is activated. The hydrostatic pressure releaser has a blade to cut the rope loop, and the hydrostatic pressure releaser 3 will automatically unhook and release the life raft 2, which will float to the surface and automatically inflate into shape.

[0026] The second is the casting state, in which the locking plate 403 is opened and the pull rod 401 is pulled back, at which time the connecting rod 402 will be disengaged, the rocker arm 5 will be laid flat, and the life raft 2 will roll into the sea along the raft frame 1 and automatically inflate into shape.
