[0025] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0026] As attached Figure 1 -Attached Figure 4 As shown, the present invention is a ship fire monitor mounting structure. The fire monitor includes a fire monitor steel pipe 1, which passes through an opening 18 on a deck 7. The fire monitor steel pipe 1 is fitted and connected to a through-tank sleeve 9. A composite material ring 10 is fitted over the outer ring of the through-tank sleeve 9. The composite material ring 10 is connected to the deck 7. The upper portion of the bracket 3 is connected to the upper portion of the outer ring of the fire monitor steel pipe 1, and the lower portion of the bracket 3 is connected to the deck 7. The above structure addresses the shortcomings of the existing technology and proposes an improved technical solution. During the structural installation, the deck is an integral part of the ship, and the fire monitor needs to be installed on the deck. The fire monitor body is connected to the fire monitor steel pipe, and the fire monitor steel pipe is connected to the deck. Specifically, when connecting a steel fire monitor steel pipe to an aluminum deck, the fire monitor steel pipe 1 passes through an opening 18 on the deck 7, extending from the upper portion of the deck 7 to the lower portion of the deck 7. The fire monitor steel pipe 1 is inserted into a through-hook sleeve 9 to securely connect the fire monitor steel pipe 1 to the through-hook sleeve 9. A composite material ring 10 is inserted into the outer ring of the through-hook sleeve 9 to securely connect the composite material ring 10 to the outer ring of the through-hook sleeve 9. The composite material ring 10 is connected to the deck 7 to securely connect the composite material ring 10 to the deck 7. A bracket 3 is also provided, with the upper portion of the bracket 3 connected to the upper portion of the outer ring of the fire monitor steel pipe 1 and the lower portion of the bracket 3 connected to the deck 7. In this way, the connection between the steel fire monitor steel pipe 1 and the aluminum deck 7 is reliably achieved, and the overall structure of the fire monitor arrangement structure is strengthened, enabling the installation of the fire monitor and its penetration through the deck, effectively meeting the reliable arrangement of the fire monitor and improving the service life of the entire structure. The ship fire monitor installation structure of the present invention has a simple structure, effectively solves the problem of pipe installation on a ship deck, achieves reliable fixation and load bearing, improves installation reliability, and meets service requirements.

[0027] Multiple brackets 3 are arranged around the outer circumference of the monitor steel pipe 1. Each bracket 3's upper portion is connected to a ring-shaped panel 2, which is attached near the top of the monitor steel pipe 1. Each bracket 3's lower portion is connected to a composite material layer 4, which is connected to an aluminum plate layer 5, which is connected to an annular backing plate 6, which is connected to a deck 7. The annular backing plate 6 is located around the outer circumference of the monitor steel pipe 1. In this structure, the brackets are metal sheets, arranged at equal angles around the circumference. Each bracket's upper and lower portions are connected, effectively improving support for the monitor steel pipe and enhancing its placement reliability, facilitating the deployment of the monitor body (fire monitor). The brackets 3, welded to the monitor steel pipe (water monitor steel pipe) 1, are welded to the aluminum deck 7 via the strip-shaped composite material layer 4, the strip-shaped aluminum plate layer 5, and the aluminum annular backing plate 6. Both the monitor steel pipe 1 and the brackets 3 are welded to the steel annular panel 2. The function of the aluminum plate layer 5 is to prevent direct welding between the composite layer 4 and the aluminum annular pad 6, reduce the area of ​​the composite surface of the composite material layer 4 affected by welding heat, and increase the reliability after connection.

[0028] A protective sleeve 11 is installed beneath the deck 7. This sleeve is located around the outer ring of the fire monitor steel pipe 1. Its upper end is connected to the lower deck 7, and its lower portion is connected to the hull beam 12. The deck 7 is made of aluminum, the hull beam 12 is made of aluminum, and the annular pad 6 is made of aluminum. The upper portion of the penetration sleeve 9 is welded to the outer ring of the fire monitor steel pipe 1 along its entire perimeter, while its lower portion is welded to the outer ring of the fire monitor steel pipe 1 along its entire perimeter. A recess 13 is provided beneath the composite ring 10. The lower portion of the composite ring 10 is welded to the outer ring of the penetration sleeve 9, while its upper portion is welded to the outer ring of the penetration sleeve 9. The outer ring of the composite ring 10 is welded to the deck 7. In this structure, the steel penetration sleeve 9, welded to the water monitor steel pipe 1, is welded to the aluminum deck 7 via the circular composite ring 10. The composite ring has uniform thickness at all locations, making it impossible to weld it from both sides to the steel penetration casing 9 without additional welding overlays. From top to bottom, the composite ring 10 consists of a steel layer 21, a titanium layer 22, and an aluminum layer 23. Therefore, during welding, the aluminum and titanium portions of the composite ring are cut away (the cutting shape should be careful to avoid stress concentration) to expose the steel portion of the composite ring 10. This allows for double-sided welding of the steel penetration casing 9 and the circular composite ring 10, while the aluminum layer 23 of the composite ring 10 is welded to the aluminum deck 7. This ensures a secure weld and connection, improves reliability, and prevents the weld from easily separating.

[0029] The outer ring of the protective sleeve 11 is welded to the hull's longitudinal reinforcement structure 8, which is connected to the lower portion of the deck 7 and perpendicular to the deck 7. In this structure, the water monitor steel pipe 1 passes through the deck and extends to the hull's transverse beam 12, avoiding the longitudinal deck girders. The aluminum protective sleeve 11 is welded to the aluminum hull transverse beam 12 and the aluminum deck 7, and also to the aluminum longitudinal reinforcement structure 8. The multiple brackets 3 function to transmit and distribute force to the hull, ensuring that the hull can bear the weight.

[0030] The ship fire monitor comprises a monitor steel pipe 1, a reducing joint 14, an extension short pipe 15, an electric butterfly valve 16, and a monitor body 17. The upper portion of the monitor steel pipe 1 is connected to the reducing joint 14, and the electric butterfly valve 16 is positioned between the reducing joint 14 and the extension short pipe 15. The monitor body 17 is flange-connected to the flange of the extension short pipe 15. The monitor is mounted on the ship's deck. The monitor mounting structure not only restrains the monitor itself, but also reacts to water reaction during use. This structure reliably provides the monitor with thrust, fixation, and support.

[0031] In the ship fire monitor installation structure described in the present invention, the deck is a component of the ship, and the fire monitor needs to be installed on the deck 7. The fire monitor body is connected to the fire monitor steel pipe 1, and the fire monitor steel pipe 1 is connected to the deck 7. Specifically, when the fire monitor steel pipe made of steel material is connected to the deck made of aluminum material, the fire monitor steel pipe 1 passes through the opening 18 on the deck 7 and extends from the upper part of the deck 7 to the lower part of the deck 7. The fire monitor steel pipe 1 is sleeved and connected in the cabin penetration sleeve 9 to achieve a fixed connection between the fire monitor steel pipe 1 and the cabin penetration sleeve 9. The composite material ring 10 is sleeved on the outer ring of the cabin penetration sleeve 9 to achieve a connection between the composite material ring 10 and the outer ring of the cabin penetration sleeve 9. The composite material ring 10 is connected to the deck 7 to achieve a connection between the composite material ring 10 and the deck 7. At the same time, a bracket 3 is provided, the upper part of the bracket 3 is connected to the upper part of the outer ring of the fire monitor steel pipe 1, and the lower part of the bracket 3 is connected to the deck 7. In this way, the connection between the steel fire cannon steel pipe 1 and the aluminum deck 7 can be reliably achieved, and the overall structure of the fire cannon arrangement structure can be strengthened, so that the fire cannon can be installed and passed through the deck, thereby ensuring the reliable arrangement of the fire cannon and improving the service life of the entire structure.

[0032] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
