Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a high-pressure resistant underwater airbag. Background Technology

[0002] In the field of marine engineering, deep-sea operations rely heavily on various underwater auxiliary equipment, among which underwater airbags, used to provide buoyancy, assist in salvage, or support equipment, are key components. As deep-sea development continues and operating depths increase, the pressure of the underwater environment also rises dramatically, placing extremely high demands on the high-pressure resistance of underwater airbags. An underwater airbag capable of maintaining structural stability and normal function in the high-pressure environment of the deep sea is of great significance for improving the safety and efficiency of deep-sea operations.

[0003] In existing technologies, traditional underwater airbags mostly employ a single-cavity structure. Their mechanical support primarily relies on the strength of the airbag's own materials. High-strength rubber or fiber composite materials are used to construct the airbag walls, utilizing the material's tensile and compressive properties to resist external water pressure. The technical principle involves inflating the airbag with gas to create a pressure difference between the inside and outside, providing buoyancy. Simultaneously, the material's physical properties withstand external water pressure, preventing the airbag from rupturing due to excessive pressure.

[0004] However, existing underwater airbags have a simple structural design and rely solely on the material properties to resist water pressure. Under high pressure, they are prone to pressure concentration, which can lead to excessive local stress and damage. They also have insufficient resistance to deformation. Furthermore, the simple cavity structure makes it difficult to guarantee airtightness during long-term use, which is insufficient to meet the needs of use in complex and high-pressure underwater environments. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a sterilization device for processing selenium-enriched food, which aims to improve the problems of the existing technology, such as easy damage due to pressure concentration caused by a single structure, insufficient resistance to deformation and poor airtightness.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-pressure resistant underwater airbag includes an airbag body one, an airbag body two is provided on the outer wall of the airbag body one, high-pressure resistant components are provided on the inner walls of both the airbag body one and the airbag body two, and a splicing component is provided on one side of the outer wall of the airbag body one.

[0008] The high-pressure resistant component includes five circular support rings arranged in a linear array on the inner walls of airbag body one and airbag body two. A load-bearing layer is provided in the interlayer between airbag body one and airbag body two. A buffer layer is attached to the outer wall of the load-bearing layer. An airtight layer is attached to the outer wall of the buffer layer. Reinforcing ribs are fixedly connected between the five circular support rings. A horizontal support rod is fixedly connected to the inner wall of each circular support ring. A vertical support rod is fixedly connected to the inner wall of each circular support ring. A reinforcing block is fixedly connected to the outer wall of each vertical support rod.

[0009] Furthermore, the splicing assembly includes a connecting box, the inner wall of which is fixedly connected to one side of the outer wall of the airbag body, a connecting block is fixedly connected to the outer wall of the airbag body, a connecting rod is fixedly connected to the outer wall of the connecting block, mounting holes are provided on both the connecting rod and the inner wall of the connecting box, a bolt is threadedly connected to the inner wall of the connecting box, and a nut is rotatably connected to the lower surface of the connecting box.

[0010] Furthermore, the outer wall of the bolt is threaded into the mounting hole, and the inner wall of the nut is threaded into the outer wall of the bolt.

[0011] Furthermore, the outer wall of the connecting rod is slidably connected to the inner wall of the connecting box, and there are two connecting rods and two connecting blocks.

[0012] Furthermore, one of the connecting rods is fixedly connected to the inner wall of the connecting block on the outer wall of the airbag body, and the inner wall of the connecting box is fixedly connected to the outer wall of the airbag body.

[0013] Furthermore, the inner wall of the transverse support rod is fixedly connected to the outer wall of the vertical support rod, and the transverse support rod and the vertical support rod are arranged in a cross shape.

[0014] Furthermore, the reinforcing ribs are configured as five, and the reinforcing ribs are arranged in a circular array.

[0015] Furthermore, the load-bearing layer is made of aramid fiber, the buffer layer is made of high-strength plastic corrugated ring material, and the airtight layer is made of neoprene rubber.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, the support ring forms an overall frame through reinforcing ribs to disperse water pressure, the cross-shaped support rods work with reinforcing blocks to enhance the resistance to deformation, the load-bearing layer bears the main pressure, the buffer layer absorbs the impact, and the airtight layer ensures sealing. These elements work together to improve the high-pressure resistance performance and solve the problems of single structures being prone to damage due to pressure concentration, insufficient resistance to deformation, and poor airtightness. This invention achieves the effect of significantly improving the overall high-pressure resistance performance and adapting to complex high-pressure underwater environments.

[0018] In this invention, the connecting rod slides into the corresponding connecting box, aligns with the mounting hole, and then the bolt is inserted and tightened with the nut to achieve a stable splicing of the two airbags. This ensures that the force at the splicing point is balanced, achieving rapid assembly and disassembly of the airbags while guaranteeing the strength and stability of the splicing point. It also reduces maintenance costs and allows for flexible adjustment of the airbag specifications according to actual needs. Attached Figure Description

A reinforcing block 12 is fixedly connected to the outer wall of the vertical support rod 11, which enhances the load-bearing capacity of the vertical support rod 11 and improves the stability of the frame.

[0030] Specifically, the five circular support rings 8 inside the airbag body 1 and the airbag body 2 are connected into an integral frame by five ring array reinforcing ribs 9. The horizontal support rods 10 and vertical support rods 11 on the inner wall of the circular support rings 8 are combined in a cross shape. The reinforcing block 12 enhances the strength of the vertical support rods 11. Inside the airbag body 1 and the airbag body 2, the load-bearing layer 5 made of aramid fiber bears the main pressure, the buffer layer 6 of the high-strength plastic corrugated ring absorbs the impact pressure, and the airtight layer 7 of modified neoprene rubber ensures airtightness.

[0031] Reference Figure 1 - Figure 6The splicing assembly includes a connecting box 4. The inner wall of the connecting box 4 is fixedly connected to one side of the outer wall of the airbag body 1.

Mounting holes 13 are provided on both the connecting rod 3 and the inner wall of the connecting box 4. A bolt 14 is threadedly connected to the inner wall of the connecting box 4. The bolt 14 passes through the mounting hole 13 and is threadedly connected to a nut 15 to achieve a tight splicing of the two airbag bodies. A nut 15 is rotatably connected to the lower surface of the connecting box 4. The outer wall of the bolt 14 is threadedly connected to the inside of the mounting hole 13, and the inner wall of the nut 15 is threadedly connected to the outer wall of the bolt 14. The connecting rod 3... The outer wall is slidably connected to the inner wall of the connecting box 4. There are two connecting rods 3 and two connecting blocks 16. One connecting rod 3 and the inner wall of the connecting block 16 are fixedly connected to the outer wall of the airbag body 1. The inner wall of the connecting box 4 is fixedly connected to the outer wall of the airbag body 2. The inner wall of the horizontal support rod 10 is fixedly connected to the outer wall of the vertical support rod 11. The horizontal support rod 10 and the vertical support rod 11 are arranged in a cross shape. There are five reinforcing ribs 9, which are arranged in a ring array. The load-bearing layer 5 is made of aramid fiber. The buffer layer 6 is made of high-strength plastic corrugated ring material. The airtight layer 7 is made of neoprene rubber.

[0032] Specifically, during assembly, the connecting rod 3 on the airbag body 1 or airbag body 2 is slid into the corresponding connecting box 4, aligned with the mounting hole 13, and then the bolt 14 is threaded through the mounting hole 13 and connected to the nut 15. The airbag body 1 or airbag body 2 is fixed by tightening the two. The two connecting rods 3, connecting blocks 16 and connecting boxes 4 are installed accordingly.

[0033] Working principle: When a high-pressure resistant underwater airbag is required, the five circular support rings 8 inside the airbag body 1 and airbag body 2 are arranged in a linear array and connected by five reinforcing ribs 9 in the ring array to form an overall frame structure, which can disperse the pressure of external water pressure on the airbag. The horizontal support rods 10 and vertical support rods 11 on the inner wall of the circular support rings 8 are connected in a cross shape, and the strength of the vertical support rods 11 is enhanced by the reinforcing blocks 12, further improving the resistance to deformation. At the same time, the load-bearing layer 5 in the airbag interlayer is made of aramid fiber material, which bears the main pressure. The high-strength plastic corrugated ring of the buffer layer 6 can absorb the impact pressure. The modified neoprene rubber of the airtight layer 7 ensures the airtightness of the airbag. The three work together to improve the overall high-pressure resistance performance.

[0034] In addition, during the splicing process, the connecting rod 3 on the airbag body 1 or the airbag body 2 is slid into the corresponding connecting box 4, so that the connecting rod 3 is aligned with the mounting hole 13 on the connecting box 4. Then, the bolt 14 is passed through the mounting hole 13 and threadedly connected to the nut 15. Through the tightening action of the bolt 14 and the nut 15, the splicing and fixing of the two airbag bodies is achieved. Since there are two connecting rods 3, connecting blocks 16 and connecting boxes 4, and they are respectively installed on the two airbag bodies, the stability and force balance at the splicing point can be guaranteed.
