[0038] Example:

[0039] See also Figure 1-8 , the present invention provides a technical solution:

[0040] A ship pressure-resistant holding device for an overpressure-proof element includes a ship 1 and an anti-collision belt 2. The anti-collision belt 2 plays a role in reducing impact when the ship 1 is docked or when the ship 1 contacts other ships 1. The anti-collision belt 2 is fixedly connected to the side wall of the ship 1. The ship can refer to various types of ships such as rubber boats, motorboats, yachts, etc., and is not limited to a specific type. The ship 1 includes a hull frame 10, a ship side outer plate 11 and an upper deck 12. The upper deck 12 is fixed to the upper end of the hull frame 10, and the ship side outer plate 11 is fixedly connected to the side wall of the hull frame 10; the anti-collision belt 2 includes a first bracket 21, a second bracket 22 and a curved sheet 23. The side wall of the first bracket 21 is fixed with a first fixing tool 210. The side wall of the second bracket 22 is fixed with a second fixing tool 220, the first fixing tool 210 and the second fixing tool 220 are fixedly connected to the side wall of the hull frame 10, the first bracket 21 is fitted with the side wall of the hull frame 10 through the first fixing tool 210, and the second bracket 22 is fitted with the side wall of the hull frame 10 through the second fixing tool 220, so as to fix the curved sheet 23, and a hollow 200 is formed between the curved sheet 23 and the hull frame 10 to increase the buffering capacity. When the first bracket 21 and the second bracket 22 are joined with the PE material, the joining position will not be misaligned, and a stable joining can be achieved, thereby achieving a stable joining of the hull frame 10 and the curved sheet 23. The first bracket 21 and the second bracket 22 can be made of PE material like the hull frame 10, and the curved sheet 23 and other components that constitute the anti-collision belt 2 can also be made of PE material like the hull frame 10. By making the hull frame 10 and the crash belt 2 of the same PE material, the high bonding force of the crash belt 2 can be conveniently combined, the hollow seal in the crash belt 2 can conveniently maintain buoyancy, the first bracket 21 and the second bracket 22 and the curved sheet 23 may be composed of fiber reinforced plastic or any other material, the ship 1 may be an inflatable ship, and air is injected into the interior to maintain the shape or / and provide buoyancy. In addition, the hull frame 10 of the ship 1 is generally streamlined to reduce water resistance, and part or all of the hull of the ship 1 is composed of PE material. This may mean that part or all of the hull is composed of PE material, or that the base material is replaced in a part of the hull that is composed of other base materials such as fiber reinforced plastic, or that the reinforcement material is combined with the PE material to assist in forming the PE material, and PE refers to any material that at least partially contains polyethylene. For example, in a real-time example, the hull of PE material may be composed of ultra-high molecular weight polyethylene UHMWPE. In addition, in this list, UHMWPE may refer to a PE material with a molecular weight of 350,000 to 10,500,000 g / mol, but is not limited thereto. However, the PE in this list can include low-density polyethylene or high-density polyethylene, and is not limited to having a specific molecular weight or physical properties;

[0041] The interior of the anti-collision belt 2 is fixed with evenly arranged partitions 207, and the anti-collision belt 2 forms evenly arranged first compartments 201-206 through the partitions 207;

[0042] The hull frame 10 has evenly arranged transverse partitions 131-136 and evenly arranged longitudinal partitions 141-143 fixed inside. The evenly arranged transverse partitions 131-136 and evenly arranged longitudinal partitions 141-143 are staggered, and the evenly arranged transverse partitions 131-136 and evenly arranged longitudinal partitions 141-143 form the second compartments 301-306, the third compartments 401-406, the fourth compartments 501-506 and the fifth compartments 601-606;

[0043] A displacement measuring device 70 is fixed to the inner wall of the ship's side outer plate 11. The displacement measuring device 70 includes evenly arranged displacement sensors 700-706. Laser displacement sensors are installed at multiple positions inside and / or outside the hull to detect the deformation of the hull. If deformation above a certain degree is detected, the anti-overpressure valve installed in the compartment at that position is activated, thereby detecting the deformation of the hull itself before overpressure occurs in the hull, and responding accordingly, so that the pressure resistance remains stable.

[0044] An opening 710 is formed on the side wall of the partition plate 207 . A bolt 712 is disposed on the inner thread of the opening 710 , and a washer 711 is disposed on the outer thread of the bolt 712 .

[0045] Bolts 712 and washers 711 constitute an overpressure prevention assembly V4. Compared with the overpressure prevention valve installed in each cabin of the hull as an overpressure prevention element V4, another overpressure prevention valve with a higher operating pressure is installed between cabins. In this way, when the overpressure level generated in the hull is high, in addition to discharging air to the deck, pressure distribution will also occur in other cabins, thereby returning to the design pressure faster. The overpressure prevention element V4 is a component that is opened to prevent overpressure or to discharge air in a compartment when overpressure occurs, for example, a bolt-shaped component that is opened manually, or a valve-shaped component that can be opened manually or automatically.

[0046] All the first compartments 201-206 of the anti-collision belt 2 are installed with the first overpressure valve V2, and the first overpressure valve V2 may be installed only in some of the first compartments 201-206. When the air pressure in the first compartment 201-206 is lower than the preset pressure, the first overpressure valve V2 will maintain a shielding state in which air flow is not allowed through the first overpressure valve V2. When the air pressure in the first compartment 201-206 is higher than the set value, it will be opened to discharge the air in the first compartment 201-206 to the outside.

[0047] The setting value of the air flow allowed by the first overpressure valve V2 is determined by the design of the first overpressure valve V2 and is not limited by a specific method or value. The first overpressure valve V2 closes the air flow channel by spring force, and opens if the pressure in the first compartment 201-206 rises above the spring force of the first overpressure valve V2.

[0048] An intake valve V1 and a first overpressure valve V2 are fixed to the side walls of the first compartment 201 - 206 , the second compartment 301 - 306 , the third compartment 401 - 406 , the fourth compartment 501 - 506 , and the fifth compartment 601 - 606 .

[0049] The side walls of the evenly arranged transverse partitions 131-136 are fixed with second overpressure valves V3, and the pressure distribution between adjacent compartments is achieved through the second overpressure valves V3, thereby achieving more emphasis on eliminating pressure through external exhaust rather than dispersing the pressure inside the body, thereby realizing the action of the internal pressure maintaining device.

[0050] A polyethylene ship comprises a ship 1 and a crash belt 2, wherein the crash belt 2 is fixedly connected to the side wall of the ship 1, and the ship 1 comprises a hull frame 10, a ship side outer plate 11 and an upper deck 12, wherein the upper deck 12 is fixed to the upper end of the hull frame 10, and the ship side outer plate 11 is fixedly connected to the side wall of the hull frame 10; the crash belt 2 comprises a first bracket 21, a second bracket 22 and a curved sheet 23, a first fixing tool 210 is fixed to the side wall of the first bracket 21, a second fixing tool 220 is fixed to the side wall of the second bracket 22, the first fixing tool 210 and the second fixing tool 220 are fixedly connected to the side wall of the hull frame 10, and a hollow 200 is formed between the curved sheet 23 and the hull frame 10.
