[0019] The floating bag is an important buoyancy device widely used in marine engineering and underwater operations. However, the existing floating bag design generally adopts a simple cylindrical structure, and the end cover of the opening of the cylindrical structure is a circular structure. Although this structure has a relatively simple manufacturing process, it has significant defects. On the one hand, it cannot surround the equipment to provide buoyancy, and on the other hand, the edge of the circular end cover of the cylindrical floating bag is prone to stress concentration problems, which seriously affects the service life and safety of the floating bag. In addition, the circular end cover structure is prone to large deformation under high pressure, which may cause sealing failure.

[0020] Reference Figure 1 , Figure 2 The present application provides a saddle-shaped floating bag, which comprises a bag body 100, the bag body 100 is an annular structure, one side of the bag body 100 is provided with an opening, and both ends of the opening of the bag body 100 are provided with a tapered end head 120. An air inlet valve 200 is arranged on the bag body 100.

[0021] The saddle-shaped floating bag is in a folded state when stored, and the overall structure is a saddle-shaped structure. When used, it is directly installed at the annular groove of the equipment, and the valve on the high-pressure cylinder of the equipment is connected with the air inlet valve 200. When the equipment finishes sailing, the signal valve automatically opens the valve of the high-pressure cylinder in the equipment, and the compressed air is filled into the bag body 100 to be inflated and formed, so as to generate buoyancy to float and pull the equipment on the sea surface, facilitating salvage and recovery. The floating bag with the saddle-shaped structure can tightly embrace the equipment after inflation, so that the connection with the equipment is more closely. In addition, both ends of the floating bag of the present application are provided with a tapered structure, which can overcome the defect that the edge of the traditional circular end cover is prone to stress concentration.

[0022] In some embodiments, a safety valve 300 is provided on the bladder 100. This prevents the saddle-shaped buoyancy chamber from exploding due to over-inflation.

[0023] In the embodiments shown in the present application, two safety valves 300 are provided, and the two safety valves 300 are respectively provided on the outside of the two ends of the bladder 100.

[0024] In some embodiments, the air inlet valve 200 is provided inside the bladder 100, and the air inlet valve 200 is located in alignment with the open end 110 of the bladder 100. This arrangement facilitates connection with the valve on the high-pressure cylinder of the equipment.

[0025] In some embodiments, a connecting lug 400 is provided on the inside of the open end 110 of the bladder 100. When the saddle-shaped buoyancy chamber is installed in the annular groove reserved in the equipment and connected with the valve on the high-pressure cylinder, the connecting lugs 400 at the two ends can be connected and fastened with a rope, so that the open end 110 of the bladder 100 is tightened, and the saddle-shaped buoyancy chamber is more firmly connected with the equipment.

[0026] In some embodiments, the bladder 100 comprises a plurality of polygonal tire tube sheets 101 that are spliced together. This maximizes the volume-to-surface area ratio of the buoyancy chamber, reduces the number of glue lap joints of the bladder 100, increases the folding and packaging softness of the bladder 100, and reduces the impact of the radial and circumferential lap joints on the strength of the bladder 100. Moreover, the inner edge of the bladder 100 after inflation can closely contact the annular groove on the equipment, uniformly transmit the strong resistance of the buoyancy chamber to the equipment due to instantaneous inflation, increase the stability of the equipment, and protect the equipment from damage due to excessive stress concentration.

[0027] The tapered end 120 is a tapered structure of a sheet connected to the two ends of the bladder 100.

[0028] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples. In addition, the different embodiments or examples described in the present specification and the features of the different embodiments or examples can be combined and combined by those skilled in the art without contradiction.

[0029] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
