Technical Field
[0001] The utility model belongs to the technical field of water rescue equipment, and in particular relates to a rescue life-saving raft with a polygonal structure. Background Art
[0002] In recent years, floods and other water emergencies have shown an increasing trend year by year. As an important water rescue equipment, rescue rafts can not only provide temporary buoyancy support for trapped people when a disaster occurs, but also assist rescuers to quickly transfer victims to a safe area.
[0003] At present, the rescue life rafts on the market mainly rely on built-in inflatable devices to ensure their rapid inflation and deployment in emergency situations. This design greatly simplifies the operation process, allowing non-professionals to quickly complete the inflation operation in a tense environment. However, although the inflatable device facilitates the rapid deployment of the rescue life raft, the existing life rafts still have many shortcomings in terms of stability and comfort after inflation: on the one hand, due to the lack of advanced structural design, some life rafts are prone to capsizing in strong winds and waves, which not only affects the rescue efficiency, but may also cause secondary injuries to the rescued persons. On the other hand, under extreme weather conditions, the violent shaking of the life raft on the water surface not only consumes the physical strength of the rescued persons, but may also cause panic and anxiety, further increasing the difficulty of rescue.
[0004] In addition, existing rescue life rafts also have certain operational difficulties when the rescued persons are physically weak. For example, the boarding design of some life rafts does not conform to the ergonomic principles, resulting in greater difficulties for the rescued persons during the boarding process, which undoubtedly increases the complexity and risk of the rescue work.
[0005] In summary, the existing rescue life rafts still need to be improved in terms of stability, comfort, and ease of use. In view of these problems, how to improve the practicality and safety of rescue life rafts through structural design optimization and innovation, so as to better serve water rescue work, has practical significance for the smooth development of flood rescue work. Utility Model Content
[0006] Aiming at the many problems existing in the rescue survival rafts in the existing market in the background technology, the utility model provides a rescue survival raft with a polygonal structure.
[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rescue life raft with a polygonal structure, including an inflatable raft body, the inflatable raft body is an even-numbered regular polygon structure, a float skeleton is arranged at the bottom of the inflatable raft body, and floats equal to the sides of the inflatable raft body are arranged on the float skeleton, a plurality of the floats are located outside the inflatable raft body and arranged in pairs, a pad is arranged on each outer wall of the inflatable raft body, a plurality of the pads are located at the lower part of the inflatable raft body and arranged in pairs, and the floats and the pads are staggered.
[0008] As a further supplement to the above technical solution, a buoyancy tire with the same length as the edge of the inflatable raft is provided at the bottom of the inflatable raft, and the buoyancy tire is located below the pad. A plurality of the buoyancy tires are symmetrically arranged and the buoyancy is concentrated in the center of the inflatable raft, thereby reducing the lateral swing of the inflatable raft by suppressing side waves.
[0009] As a further supplement to the above technical solution, the buoyancy tire is made of solid buoyancy material, and a plurality of chambers are arranged in the middle of each of the buoyancy tires. Inlet and outlet water holes connected to the chambers are arranged at the bottom of the buoyancy tires. The chambers are drained and inlet and outlet water is discharged through the inlet and outlet water holes, which plays a shock-absorbing role during the bumps of the inflatable raft.
[0010] As a further explanation and limitation of the above technical solution, the buoy skeleton includes a regular polygonal base frame matching the inflatable raft body, the regular polygonal base frame is arranged at the bottom of the inflatable raft body, a sleeve is fixed at the center of the regular polygonal base frame, a locking bolt is arranged on the sleeve, the lower end of the support rod is inserted in the sleeve and connected to the regular polygonal base frame with a locking bolt, a plurality of inverted J-shaped connecting rods are fixedly connected to the upper end of the support rod, the plurality of inverted J-shaped connecting rods are radiated from the center of the regular polygonal base frame, and the buoy is arranged at the end of the inverted J-shaped connecting rod.
[0011] As a further supplementary explanation of the above technical solution, an auxiliary handrail is arranged on each outer wall of the inflatable raft body, and the auxiliary handrail is rotatably connected to the inflatable raft body.

[0013] As a further explanation and limitation of the above technical solution, the inflatable raft body is a regular hexagonal structure.
[0014] Compared with the existing rescue life rafts, the rescue life raft with a polygonal structure designed by the utility model has the following advantages:
[0015] 1. The utility model designs the inflatable raft body into a regular polygon structure, and at the same time sets a pad on the inflatable raft body and sets a floating ball through an inverted J-shaped connecting rod. The combined design of the inverted J-shaped connecting rod and the floating ball enables the rescue life raft to quickly restore to a stable state when impacted and is not easy to capsize. The staggered arrangement of the pad and the floating ball increases the buoyancy of the rescue life raft and improves the stability of the rescue life raft in wind and waves. In addition, the rescued person can quickly and conveniently enter the inflatable raft body from any direction and any position through the pad, which reduces the difficulty of rescue and further improves the rescue efficiency.
[0016] 2. The utility model provides a floating tire made of solid buoyancy material at the bottom of the inflatable raft body, and is provided with a plurality of chambers and water inlet and outlet holes. The floating tire uses the chambers to inlet and outlet water through the water inlet and outlet holes, which can absorb impact force and correct the posture of the inflatable raft body, thereby playing a shock-absorbing role.
[0017] 3. The utility model is designed with a connecting hook, so that the rescue life raft can be connected with other life rafts, thereby increasing the rescue area and improving the stability when rescuing multiple people. In addition, the connecting hook can also be used to connect the safety rope of the rescued person, ensuring that the person can remain connected to the rescue life raft even if he falls into the water again in a harsh environment, thereby ensuring the life safety of the person. Thereby, the rescue capability and safety performance requirements of the rescue life raft are enhanced, and the survival rate of refuge is greatly increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The float frame includes: a regular polygonal base frame 201 , a sleeve 202 , a locking bolt 203 , a support rod 204 , and an inverted J-shaped connecting rod 205 . DETAILED DESCRIPTION
[0025] In order to further illustrate the technical solution of the utility model, the following Figures 1 to 5 , According to the design scheme and implementation process, we further illustrate the utility model through two embodiments. Embodiment 1
[0026] As attached Figure 1 and 2 As shown, a rescue raft with a polygonal structure includes an inflatable raft body 1. The inflatable raft body 1 is an even-numbered regular polygon structure. In this embodiment, the inflatable raft body 1 is preferably a regular hexagonal structure as an example, and other even-numbered regular polygon structures are certainly not excluded. A buoyancy ball skeleton 2 is arranged at the bottom of the inflatable raft body 1. The buoyancy ball skeleton 2 includes a regular hexagonal base frame 201 that matches the inflatable raft body 1. The regular hexagonal base frame 201 is arranged at the bottom of the inflatable raft body 1. A sleeve 202 is fixed at the center of the regular hexagonal base frame 201. A locking bolt 203 is arranged on the sleeve 202. The lower end of a support rod 204 is inserted into the sleeve 202 and connected to the regular hexagonal base frame 201 by the locking bolt 203. The upper end is fixedly connected with six inverted J-shaped connecting rods 205, and the six inverted J-shaped connecting rods 205 are radiated from the center of the regular polygonal base frame 201. The floating balls 3 are arranged at the ends of the inverted J-shaped connecting rods 205. The number of the sides of the inflatable raft body 1 is equal to the number of the floating balls 3. The six floating balls 3 are located outside the inflatable raft body 1 and are arranged in pairs. A pad 4 is provided on each outer wall of the inflatable raft body 1. The six pads 4 are located at the lower part of the inflatable raft body 1 and are arranged in pairs. The floating balls 3 and the pads 4 are staggered.
[0027] As a preferred mode of this embodiment, an auxiliary handrail 6 is provided on each outer wall of the inflatable raft body 1, and the auxiliary handrail 6 is rotatably connected to the inflatable raft body 1. The auxiliary handrail 6 is a semicircular handrail connected to the rescue life raft by two rotating pairs, so that the person who falls into the water can hug the mechanism to recover his physical strength and wait for the physical strength to recover before getting on the rescue life raft when he is exhausted and unable to get on the raft immediately. At the same time, the life-saving auxiliary handrail can also provide assistance to the trapped person when getting on the raft and play the role of assisting the raft. Compared with the auxiliary rope on the traditional rescue life raft, this structure is not only simple and convenient to get on the raft, but also will not easily cause the rescue life raft to hang in certain terrains.
[0028] As a preferred mode of this embodiment, at least two connecting hooks 7 are arranged on each outer wall of the inflatable raft body 1. The design of the connecting hooks 7 allows the life raft to be connected to other rescue life rafts from six directions, which can increase the area of the rescue life raft to rescue more trapped persons when rescuing multiple persons, and improve the stability of the rescue life raft without changing the original structure of the rescue life raft. The rescued person's safety rope can also be connected to it. In a harsh environment, even if the person falls into the water again, there is a safety rope to connect him to the rescue life raft to ensure the life safety of the person. In addition, the life raft can also use the connecting hooks 7 to connect to the external power to assist the trapped person to survive. Embodiment 2
[0029] As attached Figures 1 to 5 As shown, six buoyancy tires 5 are arranged at the bottom of the inflatable raft 1, and the buoyancy tires 5 are located below the pad 4. The six buoyancy tires 5 are symmetrically arranged and the buoyancy is concentrated at the center of the inflatable raft 1. By suppressing the side waves and reducing the lateral swing of the inflatable raft 1, the cross section of the inflatable raft 1 is close to the horizontal effect, and the manned area is increased under the same displacement. The buoyancy tires 5 are made of solid buoyancy material, and a plurality of chambers 8 are arranged in the middle of each of the buoyancy tires 5. The bottom of the buoyancy tires 5 is provided with water inlet and outlet holes 9 connected with the chambers 8. When the rescue survival raft is bumpy, the chamber 8 is squeezed by the force, and the water inside will not flow out immediately, but will flow out from the water inlet and outlet holes 9 after absorbing a certain impact force, converting the up and down movement into the pressure difference of the water. At the same time, the sprayed water will exert an upward force on the inflatable raft 1 to correct the posture of the inflatable raft 1. When the inflatable raft body 1 is restored, the water flows back into the chamber 8 through the water inlet and outlet holes 9, and this process is repeated to achieve a shock absorbing effect.
[0030] In the above embodiment, when the inflatable raft 1 rolls, the pad 4 generates resistance in the opposite direction of the roll, forms a roll-reducing moment, and creates a turbulent flow, thereby reducing the roll of the inflatable raft 1. The inflatable raft 1 is provided with auxiliary handrails 6 instead of auxiliary ropes around the floating tire 5, which ensures that the survival raft is not towed and trapped in the terrain when passing through certain terrains. After the inflatable raft 1 is inflated and formed, the rescued person can board the inflatable raft 1 from any direction and any position through the pad 4, and the boarding is fast and convenient. At the same time, an inverted J-shaped connecting rod 205 with an interval of 60 degrees in 6 directions is installed on the regular hexagonal base frame 201 at the center of the bottom of the inflatable raft 1 through a support rod 204, and a downward floating ball 3 is connected at each end of the inverted J-shaped connecting rod 205. The floating ball 3 is light and displaces a certain volume of water in the water to obtain a certain buoyancy. The floating balls 3 are arranged in 6 directions so that the rescue survival raft can remain stable no matter which direction there is an impact. When the rescue life raft is tilted by wind and waves, the buoyancy ball tilted downward will be immersed in the water and displace a certain volume of water, so that the buoyancy of the inflatable raft body 1 in the tilting direction is increased and the normal stable state is immediately restored. Therefore, compared with the traditional rescue life raft, it is less likely to capsize under wind and waves.
[0031] The above shows and describes the main features and advantages of the utility model. For those skilled in the art, it is obvious that the specific implementation of the utility model is not limited to the details of the above exemplary embodiments, and the creative ideas and design ideas of the utility model can be realized in other specific forms without departing from the spirit or basic features of the utility model, which should be equivalent to the protection scope disclosed in the technical solution of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the utility model.
