Description

Technical Field

[0001] The utility model relates to the technical field of rescue rafts, in particular to a water area rescue raft. Background Art

[0002] A water rescue raft is an important equipment used for water rescue, also known as a life raft. It is usually used for escape and rescue in emergency situations, especially when natural disasters such as shipwrecks and floods occur, and can be used by victims to help them escape from dangerous areas. There are two types of life rafts: traditional life rafts and inflatable life rafts. Traditional life rafts need to be inflated manually, while inflatable life rafts can be automatically inflated and formed for people in distress.

[0003] Existing ship life rafts have no self-powered warning, which makes it difficult for rescue teams to find the life rafts when encountering turbulent water.

[0004] An existing patent (publication number: CN219295652U) discloses an inflatable life raft, which includes a device box, an inflatable raft body and an equipment box. A photovoltaic panel and a warning light are arranged on the lifting device of the equipment box. When the entire warning light is lifted, the height of the light is increased to avoid the warning light being blocked by the fluctuation of the life raft, making it easier for the trapped persons to be found and rescued by the rescue team. The photovoltaic panel ensures that the warning light can work for a long time.

[0005] In response to the above problems, although the solution given in the existing patent makes it easier for the trapped people to be found and rescued by the rescue team by installing photovoltaic panels and warning lights, it requires an air pump to inflate during use. The air pump has a long inflation time, which may cause delays in the rescue operation and increase the risk, making it inconvenient to use. Summary of the invention

[0006] The purpose of the utility model is to provide a water rescue raft, which can automatically inflate the rescue raft body with compressed air, and the inflation speed is faster, thereby reducing delays and increased risks in rescue operations. Under the action of the spring's own elasticity, the fixed block at the end of the guide rod will be pushed to automatically seal the rescue raft body, thereby reducing gas leakage, so as to solve the problems raised in the above-mentioned background technology.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A water rescue raft comprises a rescue raft body 1, a gas storage cylinder 2 is installed on the lower surface of the rescue raft body 1, and an inflation mechanism for inflating the rescue raft body 1 is installed on the upper end of the rescue raft body 1;

[0028] The inflation mechanism includes an air intake member 5, the upper end of the air intake member 5 passes through a limit rod 51, a first magnet 52 is fixed to the outer surface of the limit rod 51, a second magnet 53 fixedly connected to the inner wall of the air intake member 5 is provided above the first magnet 52, a movable rod 54 is plugged and connected to the end of the limit rod 51, a fixed plate 56 is fixed in the vertical direction inside the air intake member 5, the end of the movable rod 54 passes through the fixed plate 56 and is fixed with a sealing member 55, two through holes 57 are provided inside the fixed plate 56, a connecting hole 510 interconnected with the rescue raft 1 is provided at the lower end of the air intake member 5, two guide rods 58 penetrating the fixed plate 56 are fixed to the right side of the sealing member 55, the outer surface of the guide rod 58 is sleeved with a spring 59 abutting against the fixed plate 56, the output end of the gas storage cylinder 2 is connected to the gas supply pipe 3, and the end of the gas supply pipe 3 is connected to the safety valve 4 interconnected with the air intake member 5.

[0029] By adopting the above technical solution, before using the rescue raft in the water area, the rescue raft body 1 is first placed on the water surface, and the safety valve 4 on the air inlet 5 is opened, so that the compressed air stored in the gas cylinder 2 can enter the air inlet 5 through the air pipe 3. Since the sealing member 55 in the air inlet 5 is in contact with the fixing plate 56, the compressed air cannot be discharged through the through hole 57. The limiting rod 51 is pulled to separate the end of the limiting rod 51 from the movable rod 54, and the first magnet 52 and the second magnet 53 are connected and fixed, so as to prevent the limiting rod 51 from resetting. At this time, under the action of the thrust of the compressed air itself, the sealing member 55 is pushed through the through hole 57 to move. The compressed air is moved so that it is discharged into the other side of the air inlet 5 through the through hole 57, and then enters the rescue raft 1 through the connecting hole 510 to realize automatic inflation. The rescue raft 1 uses compressed air to realize automatic inflation, and the inflation speed is faster, thereby reducing delays and increased risks of rescue operations. When the air in the rescue raft 1 is full, the air pressure in the rescue raft 1 and the gas storage cylinder 2 is balanced. At this time, under the action of the elasticity of the spring 59 itself, the fixing block at the end of the guide rod 58 is pushed, so that the guide rod 58 drives the sealing member 55 to contact with the fixing plate 56, and automatically seals the rescue raft 1, thereby reducing gas leakage.

[0030] Specifically, Figure 1-Figure 4 As shown, a raft climbing ladder 6 is fixed to the outer wall of the rescue raft body 1, four balancing water bags 13 are symmetrically fixed to the lower surface of the rescue raft body 1, four limiting members 7 are symmetrically fixed to the upper surface of the rescue raft body 1, and handrail ropes 8 are connected to the interiors of the four limiting members 7.

[0031] By adopting the above technical scheme, the rescued persons can board the rescue raft 1 conveniently through the raft climbing ladder 6 arranged on the rescue raft 1, the handrail rope 8 arranged in the limiter 7 is convenient for the user to support, the draw rope lock 9 is convenient for the connection with the rope and the traction equipment, the handrail frame 11 is further convenient for support, the safety knife bag 10 is equipped with a knife, and the knife can be used for winding in emergency situations, the medical bag 12 contains a medical bag and a power bank, and the medical bag and the power bank are located on the inner side of the hull to provide medical and communication support, and the balancing water bag 13 can be used to increase the stability of the raft.

[0032] Working principle: open the safety valve 4 on the air inlet 5, pull the limit rod 51 to separate the end of the limit rod 51 and the movable rod 54, and at this time, under the action of the thrust of the compressed air itself, the seal 55 is pushed to move through the through hole 57, so that the compressed air is discharged into the other side of the air inlet 5 through the through hole 57, and enters the rescue raft 1 through the connecting hole 510 to realize automatic inflation, and the rescue raft 1 uses compressed air to realize automatic inflation. When the air in the rescue raft 1 is full, the spring 59 will push the fixed block at the end of the guide rod 58 under the action of its own elasticity, so that the guide rod 58 drives the seal The sealing member 55 contacts the fixing plate 56 to automatically seal the rescue raft 1. The raft ladder 6 provided on the rescue raft 1 facilitates the rescued persons to board the rescue raft 1. The handrail rope 8 provided in the limit member 7 facilitates the user's support. The drawstring lock 9 facilitates the connection with ropes and traction equipment. The handrail frame 11 further facilitates support. The safety knife bag 10 has a built-in knife, which can be used for winding in emergency situations. The medical bag 12 contains a medical bag and a power bank, which are located on the inner side of the hull to provide medical and communication support. The balancing water bag 13 can be used to increase the stability of the raft.
