AI Technical Summary
Existing bloating life rafts are prone to overturn when used, resulting in lifeguards who need professional training going to the sea to get upright, and may overturn again in strong winds and waves, endangering life. At the same time, the setting of the sling column occupies the space of the raft, affecting personnel movement and the interior space of the tent.
A self-reinforced and positive gas inflation life raft is designed, using a combined structure of an inflatable keel and a flexible bracket. The inflatable keel is isolated from the inner cavity of the raft. The flexible bracket can be rotated to form a circular arch to support the tent covering cloth, and the buoyancy tube and balanced water bag are used for self-reliance and stability.
When protection is not required, the inflatable keel can deflate and enhance the raft space. The design of the flexible bracket increases the internal space of the tent, improves the range of personnel movement and the raft load-bearing capacity, and reduces the risk of overturning.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rescue devices, and particularly relates to a self-righting inflatable life raft. Background Technique
[0002] At present, existing inflatable life rafts generally adopt a throwable or suspendable structure. When a ship is in distress and the inflatable life raft is used emergently and thrown and inflated, a large part of the life rafts are in a capsized state. At this time, it is necessary for a lifeguard trained professionally to go into the sea to right the capsized life raft, and then the people in distress can take shelter in the life raft. During the drifting process of taking shelter, if there are strong winds and big waves, the life raft may also be overturned by huge waves, and at this time, the people in distress will fall into the water and be in danger of life.
[0003] In the prior art, there is a self-righting life raft. For example, a self-righting inflatable life raft with the publication number of CN219312997U includes a raft bottom. A lower buoyancy tube and an upper buoyancy tube are arranged at the top of the raft bottom near the edge, and the lower buoyancy tube and the upper buoyancy tube are overlapped and arranged above the raft bottom. An arc-shaped awning column spanning the raft bottom is arranged at the top of the upper buoyancy tube. A tent is arranged at the top of the arc-shaped awning column, and the bottom end of the tent is arranged on the top surface of the upper buoyancy tube. A water collecting groove and a water collecting bag are arranged on one side of the outer wall of the tent.
[0004] An awning column is arranged on the top surface of this life raft, and thus a tent is arranged on the awning column. However, the raft body is integrally formed with the awning column. When protection is not required on the raft body, the arrangement of the awning column occupies the space area of the raft body, which affects the movement of the people on the raft body to a certain extent, thus bringing inconvenience to the rowing of the life raft. At the same time, the tent is supported by the awning column, and the volume of the tent will be compressed where there is no awning column, so the internal space of the tent on the top surface of the life raft is reduced, affecting the internal protection volume. Summary of the Invention
[0005] The purpose of the utility model is to solve the problems that when the awning column does not need to provide protection and shielding, it will affect the rowing of the raft body by people and cause inconvenience, and the volume of the tent will be reduced where there is no awning column, and a self-righting inflatable life raft is proposed.

Both sides of each inflatable keel are connected to both sides of the raft body, and the inflatable keel is isolated from the inner cavity of the raft body. Rotating seats are arranged on both sides of the raft body, and flexible brackets are rotatably arranged in the rotating seats. Connecting cylinders and connecting heads are respectively arranged at the ends of the flexible brackets on both sides close to each other. A plurality of brackets on both sides are fixedly connected through the connecting cylinders and the connecting heads to form a circular arch shape. A tent cover is arranged on the top surface of the circular-arch-shaped flexible bracket and the inflatable keel.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-3 As shown, the present utility model is a self-righting inflatable life raft, including a raft body 1. A circle of buoyancy tubes 2 is arranged at the bottom of the raft body 1, and a plurality of balance water bags 3 are arranged at the bottom of the buoyancy tubes 2. Inflatable keels 4 are arranged on both sides of the top surface of the raft body 1. There are two inflatable keels 4 on the top surface of the raft body 1. The two ends of one inflatable keel 4 are connected to both sides of the raft body 1, and the inner cavity of the inflatable keel 4 is separated from the inner cavity of the raft body 1. A support belt 5 is arranged between the two inflatable keels 4, and the support belt 5 is communicated with the inner cavities of the two inflatable keels 4. Rotating seats 6 are arranged on both sides of the raft body 1. There are two rotating seats 6 on one side of the raft body 1, and the two rotating seats 6 are located at the front and rear sides of the raft body 1. A flexible bracket 7 is rotatably arranged in each rotating seat 6. One end of the flexible brackets 7 on both sides of the raft body 1 is respectively provided with a connecting cylinder 8 and a connecting head 9. The connecting head 9 and the connecting cylinder 8 can be engaged with each other, and the two flexible brackets 7 after engagement can form an arch shape. An elastic tent cover 10 is arranged on the top surface of the raft body 1, and the tent cover 10 sequentially contacts above the flexible brackets 7 and the inflatable keels 4.
[0024] When using this self-righting inflatable life raft, the buoyancy tubes 2 and the balance water bags 3 on the bottom surface of the raft body 1 enable the raft body 1 to be stable on the water surface. When the raft body 1 shakes on the water surface, the buoyancy tubes 2 and the balance water bags 3 will callback the raft body 1 itself, so as to self-right and prevent the raft body 1 from capsizing. The inner cavity between the raft body 1 itself and the inflatable keel 4 is not connected, and the inflatable keel 4 is restarted separately, so that the inflatable keel 4 can be deflated during use to increase the space on the top surface of the raft body 1, and the activity range of people and the bearing capacity of the raft body 1 can be increased when no shelter is needed. When protection is required, the inflatable keel 4 is restarted through the air pump 11. Then, one end of the two corresponding flexible brackets 7 on both sides is brought closer, and the connector 9 and the connecting cylinder 8 at one end of the flexible bracket 7 are fixedly connected, so that the two flexible brackets 7 form an arch. Then, a tent cover 10 is arranged on the top surface of the raft body 1, and the tent cover 10 contacts from above the arch-shaped flexible bracket 7 and the inflatable keel 4, so as to support the tent cover 10. By rotating the flexible bracket 7, the arch-shaped flexible bracket 7 can rotate relatively through the rotating seat 6, so as to adjust the size of the tent cover 10 and increase the internal space when the tent is blocked.
[0025] Wherein, air pumps 11 are arranged on both sides inside the raft body 1. The air pumps 11 on both sides are convenient for inflating the inflatable keel 4 and the raft body 1 near them. A soft ladder 12 is arranged on one side of the raft body 1, and the soft ladder 12 enables users to board the raft body 1 through the soft ladder 12.
[0026] The working principle of the present utility model: A self-righting inflatable life raft of the present utility model, by arranging the inflatable keel 4, the inner cavity between the inflatable keel 4 and the raft body 1 is isolated from each other, so that the inflatable keel 4 is inflated separately; when no protection is needed, the inflatable keel 4 is not inflated to increase the space on the top surface of the raft body 1, and the activity range of people and the bearing capacity of the raft body 1 can be increased when no shelter is needed; by arranging the flexible brackets 7, the two flexible brackets 7 on both sides can be relatively fixed to form an arch, and the arch-shaped flexible brackets 7 can rotate relatively on the top surface of the raft body 1. A tent cover 10 is arranged on the top surface of the flexible bracket 7 and the inflatable keel 4. The arrangement of the flexible brackets 7 can increase the internal space volume of the tent cover 10, so as to increase the protective shielding space of the tent; at the same time, the flexible brackets 7 can rotate relatively to adjust the internal volume of the tent; when not in use, the flexible brackets 7 can be rotated to one side of the top surface of the raft body 1 through the rotating seat 6 for storage, so as not to affect the movement of the people on the raft body 1.
