Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a marine high-expansion foam fire extinguishing device. Background Technology

[0002] During ship navigation and operations, the fuel, cargo (such as flammable materials in containers), and power systems carried by ships all pose a high risk of fire. Marine fire extinguishing systems, as key equipment for ensuring ship safety, are crucial in terms of reliability, response speed, and adaptability to special ship operating conditions. Among these, high-expansion foam fire extinguishing systems, with their advantages of wide foam coverage, high extinguishing efficiency, and minimal secondary damage to equipment, are widely used for fire prevention in areas such as ship engine rooms, cargo holds, and decks.

[0003] However, the navigation environment on ships differs significantly from that on land, and existing marine high-expansion foam fire extinguishing devices still have the following technical shortcomings in practical applications, making it difficult to fully meet the needs of emergency response to ship fires and the long-term stable operation of the equipment: The existing marine high-expansion foam fire extinguishing devices are mostly installed and supported by rigid connections. When the ship rolls significantly, the fire extinguishing device body will undergo violent displacement in the lateral or vertical direction, which may not only hit the hull support plate, but also cause the internal foam mixture to slosh and overflow.

[0004] Therefore, we propose a marine high-expansion foam fire extinguishing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a marine high-expansion foam fire extinguishing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A marine high-expansion foam fire extinguishing device includes two hull support plates, both of which are fixedly mounted on a support surface. A bottom buffer mechanism is also fixed between the two hull support plates. The top of the bottom buffer mechanism is equipped with the fire extinguishing device body. The bottom buffer mechanism is used to support the fire extinguishing device body and buffer the fire extinguishing device body when it moves slowly. Two soft side support structures are also symmetrically installed on the two hull support plates. The two soft side support structures are used to provide soft support on both sides of the fire extinguishing device body. A stirring mechanism is also installed on the back side wall of the fire extinguishing device body. The stirring mechanism is used to quickly stir the foam mixture inside the fire extinguishing device body to achieve rapid response. The top of the fire extinguishing device body is also provided with a foaming agent adding mechanism, which is used to store foaming agent and release foaming agent into the interior of the fire extinguishing device body when activated, so as to achieve separate storage.

[0007] As a preferred embodiment of this utility model, the bottom buffer mechanism includes a base, which is fixedly installed between two hull support plates. Several dampers are installed at the bottom inside the base, and buffer springs are provided on the outer side of the dampers. Several guide grooves are also provided on the two side walls inside the base. Guide sliders are slidably connected inside the guide grooves. Lifting plates are provided at the connection points of the guide sliders. Mounting plates are fixedly connected to the inner side walls of the two lifting plates.

[0008] As a preferred embodiment of this utility model, the side soft support structure includes a support plate, which is fixed to the side wall of the fire extinguishing device body. A sliding shaft is also fixedly connected to the side wall of the support plate. The sliding shaft passes through the hull support plate. A limit plate is fixed to one end of the sliding shaft. A first support spring is provided between the limit plate and the hull support plate, and a second support spring is provided between the support plate and the hull support plate.

[0009] As a preferred embodiment of this utility model, the stirring mechanism includes a mounting base, which is fixedly mounted on the back side wall of the fire extinguishing device body. Two first rotating shafts are provided on the front of the mounting base and inside the fire extinguishing device body. A first gear is provided on each of the two first rotating shafts and outside the fire extinguishing device body. A stirring pile is fixed on each of the two first rotating shafts and inside the fire extinguishing device body. A second gear is also provided between the two first gears. A second rotating shaft is provided inside the second gear. A servo motor is provided on the input end of the second rotating shaft.

[0010] As a preferred embodiment of this utility model, the foaming agent adding mechanism includes a storage box, which is fixedly installed on the top of the fire extinguishing device body. An adding pipe is provided at the bottom of the storage box, and a solenoid valve is also provided on the adding pipe. A water inlet pipe is also provided on the left side of the storage box.

[0011] As a preferred embodiment of this utility model, the adding tube penetrates the top of the fire extinguishing device body and connects to the interior of the fire extinguishing device body. The servo motor is used to drive the second rotating shaft to rotate, and then drives the two first gears to rotate through the second gear. When the two first gears rotate, they synchronously drive the two mixing piles to rotate, so as to achieve rapid mixing of foaming agent and water.

[0012] As a preferred embodiment of this utility model, when the fire extinguishing device body is subjected to bumps, it will be cushioned by the mounting plate. The mounting plate slides on several guide grooves through the support plate and several guide sliders, thereby compressing and cushioning the buffer spring and damper.

[0013] As a preferred embodiment of this utility model, when the fire extinguishing device body moves slowly, it also compresses the second support spring and sliding shaft through the support plate to achieve soft support on the side. At the same time, depending on the size of the fire extinguishing device body and the space between the two hull support plates, a damping device can be added between the support plate and the hull support plate to further improve stability or achieve a buffering effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the bottom buffer mechanism, through the combination of a damper and a buffer spring within the base, can directly absorb the impact force generated by the device's vertical swaying. Simultaneously, in conjunction with the sliding limit of the guide groove and guide slider, it ensures that the lifting plate, driving the mounting plate, only smoothly buffers in the vertical direction. The side soft support structure, through the design of a support plate, a sliding shaft, and two support springs (a first support spring and a second support spring), can simultaneously buffer the lateral force generated by the ship's left-right swaying: when the device moves laterally, the support plate compresses the second support spring, and the sliding shaft drives the limit plate to compress the first support spring. The two springs work together to form a reverse buffer force, preventing the device from directly impacting the ship's support plate. Furthermore, damping devices can be flexibly added according to the device size and ship space to further enhance lateral stability.

[0015] By storing the foam agent in a separate storage box, completely isolating it from the water inside the fire extinguishing device, the foam agent's sedimentation, stratification, or chemical deterioration (such as surfactant failure) caused by traditional premixed storage is avoided. This not only ensures the original performance of the foam agent but also eliminates the need for regular cleaning and replacement of the premixed solution, reducing maintenance costs and workload.

[0016] The mixing mechanism uses a servo motor as its power source, which drives the second gear to rotate through the second rotating shaft. The second gear then meshes with the two first gears to drive the two first rotating shafts to rotate the corresponding mixing piles synchronously. This transmission structure ensures that the two mixing piles rotate at the same speed and coordinate their directions (without directional conflict). Compared with traditional single-shaft mixing, the mixing range covers the interior of the fire extinguishing device more comprehensively, which can quickly break the stratification of foam agent and water and avoid local eddies or sedimentation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Example like Figure 1-6 As shown, this utility model provides a technical solution: a marine high-expansion foam fire extinguishing device, including two hull support plates 10, both of which are fixedly mounted on the support surface; a bottom buffer mechanism 20 is also fixedly provided between the two hull support plates 10, and a fire extinguishing device body 30 is provided on the top of the bottom buffer mechanism 20. The bottom buffer mechanism 20 is used to support the fire extinguishing device body 30 and buffer the fire extinguishing device body 30 when slow movement occurs; two side soft support structures 40 are also symmetrically installed on the two hull support plates 10, and the two side soft support structures 40 are used to provide soft support on both sides of the fire extinguishing device body 30; a stirring mechanism 50 is also installed on the back side wall of the fire extinguishing device body 30, and the stirring mechanism 50 is used to quickly stir the foam mixture inside the fire extinguishing device body 30 to achieve rapid response; a foam agent adding mechanism 60 is also provided on the top of the fire extinguishing device body 30, and the foam agent adding mechanism 60 is used to store foam agent and release the foam agent into the interior of the fire extinguishing device body 30 when activated, achieving separate storage.

[0024] First, two hull support plates 10 provide a stable installation foundation for the entire device, ensuring that the device is fixed to the support surface of the ship. When the ship is sailing and experiences turbulence or slow movement, the bottom buffer mechanism 20 first bears the weight and impact load of the fire extinguishing device body 30, absorbing the impact energy through its own structural deformation or relative movement of components, thus preventing the fire extinguishing device body 30 from directly bearing severe vibration. At the same time, the side soft support structures 40 on both sides work synchronously. When the fire extinguishing device body 30 shows a tendency to shift left and right, the elastic deformation or sliding buffer of the soft support components limits the lateral displacement of the body, preventing the body from rigidly colliding with the hull support plate 10. When fire extinguishing is required, the foam agent adding mechanism 60 first releases the stored foam agent into the fire extinguishing device body 30. Then, the stirring mechanism 50 is activated to quickly stir the foam agent and water inside the body, so that the two are evenly mixed to form a qualified foam mixture, which can be used for fire extinguishing operations in a timely manner through the subsequent foam release components. The entire process, through the coordinated cooperation of various mechanisms, ensures the stability of the device under special working conditions of the ship and realizes the rapid preparation of the foam mixture.

[0025] The bottom buffer mechanism 20 includes a base 201, which is fixedly installed between two hull support plates 10. Several dampers 202 are installed at the bottom inside the base 201. Buffer springs 203 are provided on the outer side of the dampers 202. Several guide grooves 204 are also provided on the two inner side walls of the base 201. Guide sliders 207 are slidably connected inside the guide grooves 204. Lifting plates 206 are provided at the connection points of the guide sliders 207. Mounting plates 205 are fixedly connected to the inner side walls of the two lifting plates 206.

[0026] The base 201 is fixedly connected to two hull support plates 10, forming a fixed frame for the bottom buffer mechanism 20. The fire extinguishing device body 30 is placed on the mounting plate 205, which is connected to the guide slider 207 via the lifting plate 206. When the fire extinguishing device body 30 is subjected to vertical shaking force, the force is transmitted to the mounting plate 205, thereby driving the lifting plate 206 to move synchronously. When the lifting plate 206 moves, the guide sliders 207 on both sides slide vertically along the guide grooves 204 on the side wall of the base 201. The cooperation between the guide grooves 204 and the guide sliders 207 can strictly limit the movement direction of the lifting plate 206 and prevent it from shifting laterally. At the same time... When the lifting plate 206 moves downward, it compresses the damper 202 and the buffer spring 203 below. The buffer spring 203 converts part of the impact energy into elastic potential energy through elastic deformation, achieving initial buffering. The damper 202 consumes the impact energy through the viscous resistance of the internal damping medium or component friction, suppressing the rebound oscillation after buffering and reducing the vibration amplitude of the fire extinguishing device body 30. When the bumping force weakens or disappears, the elastic potential energy of the buffer spring 203 is released, causing the lifting plate 206 and the mounting plate 205 to reset. The damper 202 continues to suppress the oscillation during the reset process, ensuring that the fire extinguishing device body 30 smoothly returns to the initial position, thereby achieving effective support and buffering for the body.

[0027] The side soft support structure 40 includes a support plate 401, which is fixed to the side wall of the fire extinguishing device body 30. A sliding shaft 402 is also fixedly connected to the side wall of the support plate 401. The sliding shaft 402 passes through the hull support plate 10. A limit plate 403 is fixed to one end of the sliding shaft 402. A first support spring 404 is provided between the limit plate 403 and the hull support plate 10, and a second support spring 405 is provided between the support plate 401 and the hull support plate 10.

[0028] The support plate 401, fixed to the side wall of the fire extinguishing device body 30, becomes the connecting carrier between the side soft support structure 40 and the body. When the ship rolls from side to side, causing the fire extinguishing device body 30 to move laterally, the body drives the support plate 401 to move to one side simultaneously. If the support plate 401 moves towards the hull support plate 10, it will directly compress the second support spring 405 located between the two. The second support spring 405 undergoes elastic deformation, generating a support force opposite to the direction of movement, initially offsetting the lateral impact force. At the same time, when the support plate 401 moves, it will drive the sliding shaft 402 to slide along the through hole of the hull support plate 10. The limiting plate 403 at the end of the sliding shaft 402 will then move towards the hull support plate 10. The 0-direction approach compresses the first support spring 404 between the limiting plate 403 and the hull support plate 10, and the first support spring 404 further generates a reverse elastic force, forming a secondary buffer. The synergistic effect of the first support spring 404 and the second support spring 405 can significantly reduce the lateral impact force through double elastic buffering, preventing the fire extinguishing device body 30 from directly impacting the hull support plate 10. The setting of the limiting plate 403 can prevent the sliding shaft 402 from detaching from the through hole of the hull support plate 10, ensuring structural integrity. At the same time, by limiting the maximum sliding distance of the sliding shaft 402, it can prevent the support spring from being damaged due to excessive deformation, ultimately achieving soft support and buffer protection for both sides of the fire extinguishing device body 30.

[0029] The mixing mechanism 50 includes a mounting base 501, which is fixedly mounted on the back side wall of the fire extinguishing device body 30. Two first rotating shafts 502 are provided on the front of the mounting base 501 and inside the fire extinguishing device body 30. A first gear 503 is provided on each of the two first rotating shafts 502 and on the outside of the fire extinguishing device body 30. A mixing pile 504 is fixed on each of the two first rotating shafts 502 and inside the fire extinguishing device body 30. A second gear 506 is also provided between the two first gears 503. A second rotating shaft 505 is provided inside the second gear 506. A servo motor 507 is provided on the input end of the second rotating shaft 505.

[0030] Mounting base 501 provides a fixing and mounting reference for all components of the stirring mechanism 50, ensuring the stability of the position of each rotating component. When stirring the foam mixture is required, the servo motor 507 is started, and the power output of the servo motor 507 is transmitted to the second rotating shaft 505, causing the second rotating shaft 505 to rotate around its own axis. When the second rotating shaft 505 rotates, the second gear 506 on its outer side rotates synchronously. Since the second gear 506 meshes with the two first gears 503, the rotation of the second gear 506 will drive the two first gears 503 to rotate synchronously in opposite directions or in the same direction through tooth surface transmission (the specific direction of rotation depends on the gear meshing method). (Decision); When the two first gears 503 rotate, they will drive the first rotating shaft 502 fixed to them to rotate synchronously. The first rotating shaft 502 is located inside the body 30 of the fire extinguishing device and has a stirring pile 504 fixed at one end. Therefore, the first rotating shaft 502 will drive the stirring pile 504 to rotate around the axis of the first rotating shaft 502 inside the body. When the two stirring piles 504 rotate synchronously, they will generate a strong stirring effect on the foaming agent and water inside the body, breaking the static state of the liquid, making the foaming agent evenly dispersed in the water, avoiding the foaming agent from settling or stratifying, thereby realizing the rapid stirring of the foam mixture and providing a basis for the rapid generation of high-expansion foam.

[0031] The foaming agent adding mechanism 60 includes a storage box 601, which is fixedly installed on the top of the fire extinguishing device body 30. The bottom of the storage box 601 is provided with an adding pipe 602, and the adding pipe 602 is also provided with a solenoid valve 603. The left side of the storage box 601 is also provided with a water inlet pipe 604.

[0032] The storage box 601, as an independent foam agent storage container, completely isolates the foam agent from the water inside the fire extinguishing device body 30, preventing the foam agent from settling, stratifying, or deteriorating chemically due to long-term contact with water. Under normal conditions, the solenoid valve 603 is closed, and the foam agent is sealed and stored in the storage box 601. A suitable amount of water can be added to the fire extinguishing device body 30 through the water inlet pipe 604, achieving separate storage of the foam agent and water. When it is necessary to prepare a foam mixture, the solenoid valve 603 is opened. Under its own weight or auxiliary pressure (such as the slight air pressure added to the top of the storage box 601), the foam agent in the storage box 601 flows into the fire extinguishing device body 30 through the bottom addition pipe 602. The solenoid valve 603 can precisely adjust the amount of foam agent added by controlling the degree and duration of valve opening, ensuring that the ratio of foam agent to water meets the requirements for high-expansion foam preparation. After addition is complete, closing the solenoid valve 603 stops the release of foam agent. The entire process requires no manual operation, achieving convenient and precise storage and release of foam agent, while avoiding maintenance problems associated with pre-mixed storage.

[0033] The addition pipe 602 passes through the top of the fire extinguishing device body 30 and connects to the interior of the fire extinguishing device body 30. The servo motor 507 is used to drive the second rotating shaft 505 to rotate, which in turn drives the two first gears 503 to rotate through the second gear 506. When the two first gears 503 rotate, they synchronously drive the two mixing piles 504 to rotate, so as to achieve rapid mixing of foam agent and water.

[0034] The design of the addition pipe 602 penetrating the top of the fire extinguishing device body 30 ensures that the foam agent released from the storage box 601 can directly enter the water inside the body, avoiding leakage or residue of the foam agent during the addition process and ensuring the effective utilization rate of the foam agent; when the servo motor 507 is started, the power of the servo motor 507 is transmitted sequentially to the second rotating shaft 505 and the second gear 506. The second gear 506 drives the two first gears 503 to rotate synchronously through meshing transmission. The two first gears 503 then drive the corresponding first rotating shaft 502 and the mixing pile 504 to rotate respectively; at this time If the solenoid valve 603 is open, the foaming agent continuously flows into the body through the addition pipe 602. The two synchronously rotating stirring piles 504 will immediately agitate the foaming agent and the water inside the body, so that the foaming agent is dispersed during the falling process, avoiding the foaming agent from accumulating on the water surface or settling to the bottom, and greatly shortening the mixing time. Through the precise feeding of the addition pipe 602 and the synchronous stirring of the stirring mechanism 50, the foaming agent and water can be uniformly mixed in a short time, ensuring the rapid preparation of qualified foam mixture and meeting the timeliness requirements of fire emergency response.

[0035] When the fire extinguishing device body 30 is subjected to bumps, it will be cushioned by the mounting plate 205. The mounting plate 205 slides on the guide groove 204 through the lifting plate 206 and several guide sliders 207, thereby squeezing and cushioning the buffer spring 203 and the damper 202.

[0036] When the ship experiences turbulence during navigation, and the fire extinguishing device body 30 is subjected to vertical impact loads, the weight of the body and the impact load are directly transmitted to the mounting plate 205 below. The mounting plate 205, acting as a force transmission carrier, evenly distributes the load to the lifting plates 206 on both sides. Under the load, the lifting plates 206 tend to move vertically. Since the lifting plates 206 are fixedly connected to the guide slider 207, and the guide slider 207 is embedded in the guide groove 204 on the side wall of the base 201, the lifting plates 206 will drive the guide slider 207 to slide vertically along the guide groove 204. The constraint of the guide groove 204 prevents the lifting plates 206 from shifting laterally or tilting during sliding, ensuring the stability of the buffering process. When the lifting plates 206 slide downwards, they directly compress the buffer spring 203 and the resistance spring at the bottom of the base 201. The damper 202 and the buffer spring 203 undergo elastic deformation under compression, converting impact energy into elastic potential energy and achieving initial absorption of the impact load. At the same time, the damping elements inside the damper 202 (such as damping rods and damping oil) generate a damping force that hinders the movement of the lifting plate 206, weakening the impact energy through energy dissipation and suppressing the oscillation generated when the buffer spring 203 rebounds. When the bumping force weakens, the buffer spring 203 releases its elastic potential energy, pushing the lifting plate 206 and the mounting plate 205 to return to their original position. The damper 202 continues to function, slowing down the return speed and preventing the body from rebounding violently. Thus, through the synergistic effect of the mounting plate 205, the lifting plate 206, the guide slider 207, the guide groove 204, the buffer spring 203, and the damper 202, effective buffering of the bumping impact on the fire extinguishing device body 30 is achieved.

[0037] When the fire extinguishing device body 30 moves slowly, it also compresses the second support spring 405 and the sliding shaft 402 through the support plate 401 to achieve soft support on the side. At the same time, depending on the size of the fire extinguishing device body 30 and the space between the two hull support plates 10, a damping device can be added between the support plate 401 and the hull support plate 10 to further improve stability or achieve a buffering effect.

[0038] When the ship rolls from side to side, causing the fire extinguishing device body 30 to move laterally, the body drives the fixed support plate 401 to move laterally in sync. If the body moves laterally to one side, the support plate 401 on that side will move towards the corresponding hull support plate 10. During the movement of the support plate 401, it will first compress the second support spring 405 located between itself and the hull support plate 10. The second support spring 405 generates a reverse support force through elastic deformation, initially buffering the lateral movement of the body. At the same time, the movement of the support plate 401 drives the sliding shaft 402 to slide along the through hole of the hull support plate 10. The limiting plate 403 at the end of the sliding shaft 402 moves towards the hull support plate 10, thereby compressing the first support spring 404 (between the limiting plate 403 and the hull support plate 10). A support spring 404 further generates a reverse elastic force, which together with the second support spring 405 forms a double elastic buffer, limiting the lateral displacement of the body and preventing rigid collision between the body and the hull support plate 10, thus achieving soft support on the side. If the fire extinguishing device body 30 is large or the ship's swaying amplitude is small, a damping device (such as a small damper 202) can be added between the support plate 401 and the hull support plate 10 according to actual needs. When the support plate 401 moves laterally, the damping device will absorb the energy of the lateral movement through internal damping, further suppressing the swaying of the body and reducing the rebound oscillation of the support spring, thereby improving the lateral stability of the device or enhancing the buffering effect on the basis of the original soft support, so as to adapt to the use needs of different body sizes and different swaying conditions.

[0039] It should be noted that the electrical equipment and components mentioned above are all programmed and controlled using existing PLC controllers. Since these are mature technologies, they will not be described in detail here.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
