[0027] Buoyancy systems play a vital role in marine engineering and underwater operations. While traditional buoyancy devices such as buoys and balloons are widely used, they often face challenges in deep-sea environments, such as insufficient pressure resistance and difficulty regulating buoyancy. In recent years, cylindrical bladders have become a research hotspot due to their excellent mechanical properties and controllability. By adopting a cylindrical structure, cylindrical bladders can withstand high external water pressure while flexibly adjusting the internal inflation volume to change buoyancy as needed. This design not only improves the safety and reliability of the device, but also adapts to the needs of different depths and working conditions. However, existing cylindrical bladders still have shortcomings in terms of sealing, making it difficult to meet the requirements of long-term stable operation in the complex deep-sea environment. In particular, in extreme temperatures, high pressures, and corrosive environments, the airtightness of the bladders tends to deteriorate rapidly.

[0028] Reference Figures 1 to 5 The present application provides a cylindrical float bag, including a cylindrical tape sheet 100, an end tape sheet 200, an outer protective sheet 300 and an inner protective sheet 400.

[0029] Both ends of the cylindrical tape sheet 100 have openings, and the edges of the openings at both ends of the cylindrical tape sheet 100 are provided with first curved sections 110 that bend toward the inside of the cylindrical tape sheet 100. A first through hole is provided on the cylindrical tape sheet 100, and a first valve seat 700 is installed at the first through hole. A second curved section 210 is provided on the edge of the end tape sheet 200, and an assembly step is provided on the outer surface of the second curved section 210. The end tape sheet 200 is provided at the two open ends of the cylindrical tape sheet 100, and the first curved section 110 is fitted on the assembly step of the second curved section 210. The first curved section 110 and the second curved section 210 are vulcanized and connected. A second through hole is provided on the cylindrical tape sheet 100, and a second valve seat 500 is installed at the second through hole. The outer protective sheet 300 is vulcanized on the outer butt joint of the first curved section 110 and the second curved section 210, and the inner protective sheet 400 is vulcanized on the inner butt joint of the first curved section 110 and the second curved section 210.

[0030] The cylindrical tape sheet 100 and the end tape sheet 200 of the present application are first connected by setting an assembly step between the first curved segment 110 and the second curved segment 210, and then the first curved segment and the second curved segment are vulcanized to form an staggered connection, and the outer protective sheet 300 and the inner protective sheet 400 are vulcanized to further seal the joint between the cylindrical tape sheet 100 and the end tape sheet 200. Therefore, the cylindrical airbag with a structural arrangement has good sealing performance and can meet the long-term stable working requirements in complex deep-sea environments.

[0031] The inner protection sheet 400 and the outer protection sheet 300 are both rubber sheets.

[0032] The cylindrical airbag of the present application is in a folded state when stored, and is connected to the corresponding connecting seat of the equipment through the second valve seat 500 when in use. When the equipment falls to the designed water depth, high-temperature and high-pressure gas is filled into the cylindrical airbag through the first valve seat 700. The cylindrical airbag inflates, generating buoyancy to pull the equipment out of the water, making it easy to salvage and recover.

[0033] In some embodiments, a sealing film 600 is provided on the internal joint between the first curved section 110 and the second curved section 210, and the sealing film 600 covers the bottom of the inner protective sheet 400. This can further improve the sealing between the first curved section 110 and the second curved section 210. The sealing film 600 is a rubber sheet.

[0034] In some embodiments, the second valve seat 500 includes a flange ring 510 and a sealing ring 520. The flange ring 510 is arranged on the inner and outer sides of the second through hole. The sealing ring 520 is covered on the outer side of the flange ring 510 and is vulcanized and connected to the end surface tape sheet 200.

[0035] In some embodiments, a plurality of first through holes are provided on the cylindrical adhesive tape sheet 100 , and a first valve seat 700 is installed at each of the first through holes.

[0036] In the embodiment shown in this application, three first through-holes are defined in the cylindrical tape sheet 100, each of which is fitted with a first valve seat 700. One of the first valve seats 700 serves as an inflation port, while the other two serve as pressure relief ports. During installation, the second valve seats 500 on the two end tape sheets 200 are fixed to the equipment via bolts. One of the first valve seats 700 on the cylindrical tape sheet 100 is connected to the inflation device, while the other two first valve seats 700 on the cylindrical tape sheet 100 are connected to the pressure relief valves.

[0037] In some embodiments, the first valve seat 700 includes a valve body 710 , which is connected to the inner side of the cylindrical adhesive tape 100 .

[0038] In some embodiments, the first valve seat 700 further includes a reinforcing pad 720 , which is vulcanized on the inner side of the cylindrical tape sheet 100 , and the valve body 710 is fixed between the cylindrical tape sheet 100 and the reinforcing pad 720 .

[0039] In some embodiments, the cylindrical float further includes a sealing gasket 800, which is disposed on the second valve seat 500. When the cylindrical float of the present application is connected to the equipment, the sealing gasket 800 is clamped between the equipment and the second valve seat 500, thereby performing a sealing function and improving the airtightness between the equipment and the second valve seat 500.
