Description

Technical Field

[0001] This utility model relates to the technical field of high-expansion foam generators, specifically to a marine high-expansion foam generator with multi-angle adjustment function. Background Technology

[0002] High-expansion foam generators are critical firefighting equipment specifically designed for extinguishing large-area, high-risk fires, particularly in enclosed or semi-enclosed spaces such as ship engine rooms. Their working principle involves using high-speed airflow to fully atomize foaming liquid, which then expands onto film-forming structures like foam nets to create massive foam clusters. This high-expansion foam rapidly fills the compartment, effectively isolating oxygen, inhibiting the diffusion of flammable vapors, and providing cooling, thus achieving rapid smothering and preventing reignition. Therefore, marine high-expansion foam generators are crucial, not only because of their powerful firefighting capabilities but also because they can effectively control fires in the shortest possible time, ensuring the safety of personnel and the safe navigation of the ship.

[0003] However, existing marine foam generators generally suffer from problems such as fixed structure, limited adjustment capabilities, and inconvenient maintenance. Most devices use fixed or manually adjustable brackets, making it impossible to achieve electric and precise control of the spray angle. This makes them difficult to adapt to the complex and ever-changing cabin environment and dynamic fire source locations on ships, resulting in a small fire extinguishing coverage area, slow response speed, and poor operational flexibility. In addition, key components such as foam nets are usually fixed with bolts and other fasteners, making disassembly and assembly cumbersome, time-consuming, requiring specialized tools and professional personnel. This seriously affects the efficiency of daily maintenance and emergency availability of the equipment. After long-term use, performance is prone to decline due to blockage or aging, making it difficult to meet the actual needs of modern ships for efficient, automated, and highly reliable fire-fighting equipment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a marine high-expansion foam generator with multi-angle adjustment function to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A marine high-expansion foam generator with multi-angle adjustment function includes: a connecting frame; an angle adjustment mechanism disposed at the bottom of the connecting frame for realizing multi-angle adjustment of the marine high-expansion foam generator; a high-expansion foaming component disposed at the bottom end of the angle adjustment mechanism; a liquid inlet component disposed inside one end of the high-expansion foaming component; a foaming net disposed at the other end of the high-expansion foaming component; several disassembly components disposed on the side of the foaming net near the high-expansion foaming component, and the foaming net and the high-expansion foaming component are connected through the disassembly components; and a control panel disposed on one side of the connecting frame.

[0007] Furthermore, to achieve multi-angle adjustment, the high-expansion foaming component can be infinitely, precisely, and smoothly adjusted vertically and horizontally by the first and second motors driving the up-down and left-right adjustments respectively. This adapts to different fire source locations and complex chamber environments, ensuring maximum flexibility in foam spray direction and coverage. The angle adjustment mechanism includes a first rotating frame connected to the bottom of the connecting frame. A lifting lug is provided on one side of the top of the first rotating frame. A first motor is provided on the top of the connecting frame. A first movable frame connected to the connecting frame is provided at the bottom of the first motor. The interior of the first movable frame is equipped with a mechanism for adjusting the foam spray direction. A first threaded rod is connected to the motor, and a first movable block that mates with the first threaded rod is provided on the outer side of the first threaded rod. The first movable block is connected to the lifting lug by a first connecting rod. A second motor is provided at the top of the first rotating frame, and a second movable frame connected to the first rotating frame is provided at one end of the second motor. A second threaded rod connected to the second motor is provided inside the second movable frame, and a second movable block that mates with the second threaded rod is provided on the outer side of the second threaded rod. A second rotating frame is connected to the outer side of the first rotating frame away from the connecting frame, and a connecting column is provided at the top of the second rotating frame. The connecting column is connected to the second movable block by a second connecting rod.

[0008] Furthermore, in order to generate high-expansion foam, a large amount of stable high-speed airflow is generated under the high-speed rotation of the impeller, thereby continuously generating high-expansion foam with large volume, uniform bubbles, and high stability. Through the gas-liquid synergy, the foaming efficiency and foam quality are significantly improved, ensuring that sufficient foam is generated in a short time to cover a large area of ​​fire and achieve rapid suffocation fire extinguishing. The high-expansion foaming component includes: an outer shell, located at the bottom of the angle adjustment mechanism; a third motor, located inside one end of the outer shell; an impeller, located at the end of the third motor near the foaming net; several through slots, opened at the other end of the outer shell and configured to cooperate with the disassembly component; and a limiting slot, located on the side of the through slots near the outer shell and configured to cooperate with the disassembly component. The included angle between the through slots and the limiting slots is a right angle.

[0009] Furthermore, in order to generate foam, the liquid is atomized and sprayed out through circumferentially evenly distributed nozzles under the action of the inlet pipe and the annular pipe, forming a fine liquid film. The film then passes through the foaming net, causing the atomized liquid film to rapidly extend, stretch, and wrap air on the surface of the foaming net. The inlet assembly includes: an inlet pipe, which is installed through one end of the outer shell; an annular pipe, which is connected to the end of the inlet pipe near the foaming net and is located on the side of the impeller near the foaming net; and several nozzles, which are installed on the side of the annular pipe near the foaming net and are connected to the annular pipe.

[0010] Furthermore, to facilitate generator maintenance, the locking state of the foaming net and high-expansion foaming component can be quickly released by pressing and rotating the sliding column, enabling tool-free and rapid disassembly of the foaming net. After maintenance, the reverse operation can be performed to complete the installation, greatly simplifying the maintenance process, shortening downtime, and improving the maintainability and reliability of the equipment. The disassembly components include a limiting cylinder located on the side of the foaming net away from the high-expansion foaming component, with a spring connected inside the limiting cylinder, and a snap-fit ​​post penetrating the limiting cylinder inside the spring; a sliding post that cooperates with the limiting cylinder is located at the end of the spring away from the high-expansion foaming component, and the snap-fit ​​post is connected to the sliding post; a placement groove that cooperates with the snap-fit ​​post is opened on the side of the foaming net closer to the high-expansion foaming component; several disassembly components are evenly arranged and circumferentially distributed on one side of the foaming net, and the cross-section of the snap-fit ​​post and the sliding post are both T-shaped structures.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model, through the connecting frame, angle adjustment mechanism, high-expansion foaming component, liquid inlet component, foaming net, disassembly component and control panel, can not only generate high-expansion foam, but also realize the all-round flexible adjustment of the spray angle to adapt to different fire source locations, improve the fire extinguishing coverage and response accuracy, and greatly improve the practical performance and operational reliability of marine foam generators.

[0012] 2. Through the angle adjustment mechanism, the high-expansion foaming components can be steplessly, precisely, and smoothly adjusted in the vertical and horizontal directions by the first motor and the second motor respectively driving the up and down and left and right adjustments. This adapts to different fire source locations and complex chamber environments, ensuring the flexibility of foam spray direction and maximizing coverage.

[0013] 3. By disassembling the components, the locking state between the foaming net and the high-expansion foaming component can be quickly released under the action of pressing and rotating the sliding column, realizing the tool-free quick disassembly of the foaming net; after maintenance, the reverse operation can be used to complete the installation, which greatly simplifies the maintenance process, shortens the downtime, and improves the maintainability and reliability of the equipment.

[0022] In one embodiment, the liquid inlet assembly 4 includes: a liquid inlet pipe 401, which is disposed through one end of the outer shell 301; an annular pipe 402, which is connected to the end of the liquid inlet pipe 401 near the foaming net 5 and is located on the side of the impeller 303 near the foaming net 5; and a plurality of nozzles 403, which are disposed on the side of the annular pipe 402 near the foaming net 5 and are connected to the annular pipe 402; under the action of the liquid inlet pipe 401 to the annular pipe 402, the liquid is atomized and sprayed out through the circumferentially evenly distributed nozzles 403 to form a fine liquid film, which then passes through the foaming net 5, causing the atomized liquid film to rapidly extend, stretch and wrap air on the surface of the foaming net.

[0023] In one embodiment, the disassembly assembly 6 includes a limiting cylinder 601 disposed on the side of the foaming net 5 away from the high-expansion foaming assembly 3. A spring 602 is connected inside the limiting cylinder 601, and a snap-fit ​​post 603 penetrating the limiting cylinder 601 is disposed inside the spring 602.

[0024] In addition, it should be noted that the control panel 7 consists of a human-machine interface (HMI) and a programmable logic control panel (PLC), and the control panel 7 is electrically connected to the angle adjustment mechanism 2 and the high-expansion foaming assembly 3; the control panel 7 is existing technology and will not be elaborated on further here.

[0025] In addition, it should be noted that the aforementioned connecting frame 1 is welded to the ship, and this connection is existing technology, so it will not be elaborated on here.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In practical applications, the first motor 203 is activated via control panel 7, causing the first threaded rod 205 to rotate. This causes the first moving block 206, which cooperates with the first moving frame 204, to move up and down. Under the action of the first connecting rod 207, the first rotating frame 201 moves in an arc around the connecting frame 1, thus adjusting the vertical angle of the marine high-expansion foam generator. Simultaneously, the second motor 208 is activated via control panel 7, causing the second threaded rod 210 to rotate. This causes the second moving block 211, which cooperates with the second moving frame 209, to move left and right. Under the connection of the second connecting rod 214, the second rotating frame 212 moves in an arc around the first rotating frame 201, thus adjusting the horizontal angle of the marine high-expansion foam generator. This continues until the high-expansion foaming component is adjusted to the appropriate angle. The first motor 203 and the second motor 208 are then stopped via control panel 7. Finally, the third motor 302 is activated via control panel 7. This drives the impeller 303 to rotate, providing a large volume of high-speed airflow. Simultaneously, a mixture of water and foaming agent is introduced into the inlet pipe 401, flowing into the annular pipe 402 and being sprayed out through the nozzle 403. Under the action of the large volume of high-speed airflow, high-expansion foam is generated for rapid fire extinguishing. When the marine high-expansion foam generator needs to be disassembled for maintenance, pressing the sliding column 604, and under the elastic contraction of the spring 602, causes the locking column 60... 3. The foam net 5 is no longer locked into the limiting groove 305. The sliding column 604 is rotated so that the locking column 603 is aligned with the through groove 304. Under the elastic recovery action of the spring 602, the locking column 603 no longer locks the foam net 5 into the high-expansion foaming component 3. This facilitates quick maintenance. After maintenance, the sliding column 604 is pressed and, under the elastic contraction action of the spring 602, the locking column 603 is rotated so that it is locked into the limiting groove 305 again, thus realizing the installation of the foam net 5.

[0028] In summary, by utilizing the above-mentioned technical solution of this utility model, through the connecting frame 1, angle adjustment mechanism 2, high-expansion foaming component 3, liquid inlet component 4, foaming net 5, disassembly component 6, and control panel 7, not only can high-expansion foam be generated, but the spray angle can also be flexibly adjusted in all directions to adapt to different fire source locations, improve fire extinguishing coverage and response accuracy, and significantly enhance the practical performance and operational reliability of marine foam generators. Through the angle adjustment mechanism 2, under the action of the first motor 203 and the second motor 208 respectively driving the up and down and left and right adjustments, the high-expansion foaming component 3 can be steplessly, precisely, and stably adjusted in the vertical and horizontal directions, adapting to different fire source locations and complex cabin environments, ensuring the flexibility of foam spray direction and maximizing coverage. Through the disassembly component 6, under the action of pressing and rotating the sliding column 604, the locking state of the foaming net 5 and the high-expansion foaming component 3 can be quickly released, realizing tool-free quick disassembly of the foaming net. After maintenance, the reverse operation can be used to complete the installation, greatly simplifying the maintenance process, shortening downtime, and improving the maintainability and reliability of the equipment.
