A fireproof and explosion-proof wall

Abstract

This invention provides a fireproof and explosion-proof wall, including a fixed frame and multiple fireproof energy-absorbing modules disposed on the fixed frame. Each fireproof energy-absorbing module includes a capsule, a fire extinguishing agent located within the capsule, and a mounting base. The capsule is disposed on the mounting base. A mounting groove is provided on the fixed frame, and the mounting base is fixed within the mounting groove. Using this technical solution, the capsule is filled with fire extinguishing agent, and pressure relief grooves are evenly distributed on the explosion-facing surface of the capsule. Under the action of an explosion shock wave, the capsule deforms to absorb the shock wave energy, achieving a buffering and energy-absorbing effect. When the internal pressure exceeds a critical threshold, the pressure relief grooves rupture, and the capsule sprays fire extinguishing agent outward to further offset some of the explosion shock wave energy. When a liquid fire extinguishing agent is used, it can absorb some of the heat of the fire, and at high temperatures, it decomposes to produce gas, increasing the internal pressure of the capsule. When the internal pressure exceeds a critical threshold, the pressure relief grooves rupture, and the capsule sprays liquid fire extinguishing agent, achieving a flame-retardant effect.

Description

Technical Field

[0001] This invention relates to a fireproof and explosion-proof wall, and more particularly to a movable, modular, and replaceable fireproof and explosion-proof wall. Background Technology

[0002] Mobile blast walls are typically made of robust materials such as steel plates, reinforcing bars, and bulletproof glass. They possess high impact resistance and blast-proof performance, capable of withstanding the impact of blast waves and fragments, thereby reducing injury and damage. Blast walls are commonly used in the following situations: construction sites, where they can isolate hazardous areas and protect workers and the surrounding environment; event venues, where they can maintain order, control crowd flow, and protect participants at large events or gatherings; and government agencies and military facilities, where they can protect government agencies, military facilities, and other important targets from terrorist attacks and other security threats. Mobile blast walls vary in design and specifications and can be customized to specific needs. They can have different sizes, weights, and protection levels to suit different application scenarios and security requirements. In general, mobile blast walls are an important safety device that provides effective protection for personnel and property from explosions and other hazardous events. For example, Chinese patent document CN103628583A discloses an assembled mobile explosion-proof wall, which consists of multiple explosion-proof wall units and can be assembled within minutes, with multiple energy-absorbing units arranged one by one within a supporting frame. Currently, there are also explosion-proof walls with fire-resistant functions, such as the lightweight, energy-dissipating, crack-resistant, fire-resistant explosion-proof wall and its construction method disclosed in Chinese patent document CN115897840A. The fire-resistant function of this type of explosion-proof wall is achieved through the flame-retardant effect of fireproof rock wool; however, this fire-resistant method can only passively retard flames and slow the spread of fire, and cannot actively extinguish fires. Therefore, how to actively extinguish fires during the explosion-proof process has become the main technical problem to be solved in this application. Summary of the Invention

[0003] Therefore, the purpose of this invention is to solve the technical problem of how to actively extinguish fires during explosion protection, and to provide a fireproof and explosion-proof wall that can absorb explosion energy and use the absorbed explosion energy to provide the power for the outward spray of the extinguishing agent, thereby realizing active fire extinguishing during explosion protection.

[0004] To achieve the above objectives, the present invention provides a fireproof and explosion-proof wall, comprising a fixed frame and a plurality of fireproof and energy-absorbing modules disposed on the fixed frame; the fireproof and energy-absorbing module comprises a bladder, a fire extinguishing agent located within the bladder, and a mounting base, wherein the bladder is disposed on the mounting base; a mounting groove is provided on the fixed frame, and the mounting base is fixed within the mounting groove.

[0005] A window is provided at the bottom of the installation slot. A part of the capsule is located on the blast-facing side of the slot bottom, and the other part passes through the window and is located on the back blast-facing side of the slot bottom.

[0006] The bottom of the installation groove is inclined, and the upper part of the groove bottom is inclined to the side of the back blasting surface, so that the blasting-facing surface of the groove bottom faces the upward direction and the back blasting surface faces the downward direction.

[0007] Multiple pressure relief grooves are provided on the side wall of the portion of the capsule located on the blast-facing side.

[0008] The bladder includes a mounting part and protrusions on both sides of the mounting part. The mounting base includes a box with an internal cavity. The mounting part is located inside the box. Through holes are provided on two opposite side walls of the box. The two protrusions pass through the two through holes and protrude to the outside of the box.

[0009] The protrusion located on the side facing the blast is the first protrusion, and the protrusion located on the side facing away from the blast is the second protrusion. The outer diameter of the first protrusion is larger than the outer diameter of the second protrusion.

[0010] A buckle seat is provided on the side of the box body near the bottom of the groove, and an installation hole is provided on the bottom of the groove. The buckle seat passes through the installation hole and engages with the anti-detachment buckle.

[0011] The fixed frame includes at least one base frame and at least one extension frame. The lower part of the base frame is fixed to the ground by anchors or bolts, and the extension frame can be spliced ​​and fixed with adjacent base frames and other extension frames through a connecting structure.

[0012] The connection structure includes a connecting buckle assembly and a connecting slot that mates with the connecting buckle assembly. The connecting buckle assembly includes a pair of connecting buckles, a return spring, a cam, and a wrench. The middle part of the connecting buckle is mounted on the mounting shaft. One end of the connecting buckle is a hook, and the other end is connected to the return spring. The cam is located between the two connecting buckles. The wrench is connected to the cam. Rotating the wrench can drive the cam to rotate, thereby actuating the connecting buckles.

[0013] Casters are also provided at the lower end of the base frame.

[0014] The fixed frame is also hinged with a diagonal brace, which is located on the back side of the explosion face. The lower end of the diagonal brace is fixed to the ground by anchor bolts or bolts.

[0015] By adopting the above technical solution, the fireproof and explosion-proof wall of the present invention has the following beneficial effects compared with the prior art:

[0016] 1. This invention can absorb and offset part of the energy of the blast shock wave during an explosion. Simultaneously, the absorbed energy can cause the bladder in the fire-resistant energy-absorbing module to rupture, allowing the solid or liquid extinguishing agent inside to spray outwards. This spray absorbs some of the heat released by the fire and provides flame retardancy, achieving fire prevention, flame retardancy, and explosion-proof effects. The bladder is filled with extinguishing agent, and pressure relief grooves are evenly distributed on the blast-facing surface. Under the action of the blast shock wave, the bladder deforms to absorb the shock wave energy, providing a buffering and energy-absorbing effect. When the internal pressure exceeds a critical threshold, the pressure relief grooves rupture, and the bladder sprays extinguishing agent outwards to further offset part of the blast shock wave energy. When a liquid extinguishing agent is used, during a fire, the liquid extinguishing agent absorbs some of the heat released by the fire, and at high temperatures, it decomposes to produce gas, increasing the internal pressure of the bladder. When the internal pressure exceeds a critical threshold, the pressure relief grooves rupture, and the bladder sprays liquid extinguishing agent, achieving fire prevention and flame retardancy effects.

[0017] 2. After the fireproof and explosion-proof wall of the present invention is subjected to an explosion impact, some of the energy is converted into the kinetic energy of the fire extinguishing agent that is sprayed outward. Therefore, only part of the energy generated by the explosion is absorbed by the fixed frame, thus reducing the damage rate of the fixed frame. The damaged fireproof energy-absorbing module can be replaced on the undamaged fixed frame to achieve a fast, convenient and efficient restoration and repair function.

[0018] 3. The fireproof and explosion-proof wall of the present invention can be assembled both horizontally and vertically, making it very flexible;

[0019] 4. A window is provided at the bottom of the installation slot, so that part of the bladder is located on the back blast side of the slot bottom. After the bladder ruptures, the extinguishing agent can spray to both the blasting and blasted sides at the same time, which has a large area of ​​effect on the fire and can also effectively block the fire on the back blast side.

[0020] 5. For ground explosions, the impact of the blast will spread upwards. Therefore, by tilting the bottom of the tank so that the blast-facing side faces upwards and the blast-repellent side faces downwards, the extinguishing agent will spray into the air when the bladder ruptures on the blast-facing side, as much as possible in the direction of the explosion's spread. Because the fireproof and blast-resistant wall blocks the blast impact, the blast wave affects the high-altitude area on the blast-repellent side less, while the fire will spread to the blast-repellent side at lower levels. Therefore, after the bladder ruptures, the extinguishing agent will spray downwards on the blast-repellent side, effectively preventing the fire from spreading on the blast-repellent side.

[0021] 6. Multiple pressure relief grooves are provided on the side wall of the part of the bladder facing the blast, making it easier for the side wall of the bladder facing the blast to break, ensuring that most of the extinguishing agent splashes to the blast facing.

[0022] 7. The outer diameter of the first protrusion is larger than that of the second protrusion, ensuring that most of the extinguishing agent is located on the blast-facing side. At the same time, the second protrusion protrudes outward through the through hole in the side wall of the box, so that the part of the side wall of the box located at the edge of the through hole can withstand the pressure of the extinguishing agent during the rupture process and form a reaction force on the extinguishing agent, reducing the amount of extinguishing agent sprayed through the through hole to the blast-facing side, so that most of the extinguishing agent is sprayed towards the blast-facing side. At the same time, the second protrusion can also buffer a small part of the explosion impact.

[0023] 8. The fixed frame includes a base frame and an extension frame, so it can be spliced ​​and expanded to set the area of ​​the fireproof and explosion-proof wall according to the actual needs of the explosion-proof area.

[0024] 9. The fireproof and explosion-proof wall can be easily moved using the casters at the bottom of the base frame;

[0025] 10. Diagonal bracing provides strong support for the fireproof and blast-resistant wall, preventing it from collapsing during an explosion. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1-4 As shown, a fireproof and explosion-proof wall according to the present invention includes an upright fixed frame 1 and multiple fireproof energy-absorbing modules 2 disposed on the fixed frame 1. The surface of the fixed frame 1 is sprayed with a fireproof and high-temperature resistant coating. The fixed frame 1 includes multiple base frames 4 and multiple extension frames 5. The lower part of the base frame 4 is fixed to the ground by anchor bolts 9. The extension frames 5 can be spliced ​​and fixed to adjacent base frames 4 and other extension frames 5 through a connecting structure.

[0038] In this embodiment, as Figure 5 As shown, the connection structure includes a connecting buckle assembly 6 and a connecting slot 6a that mates with the connecting buckle assembly 6. The connecting buckle assembly 6 and the connecting slot 6a are respectively disposed on the side walls of adjacent base frames 4 or extension frames 5. The connecting buckle assembly 6 includes a pair of connecting buckles 13, a return spring 15, a cam 16, and a wrench 14. The middle part of the connecting buckle 13 is mounted on the mounting shaft 171. One end of the connecting buckle 13 is a hook, and the other end is connected to the return spring 15. The cam 16 is located between the two connecting buckles 13. The wrench 14 is connected to the cam 16. Rotating the wrench 14 can drive the cam 16 to rotate, thereby actuating the connecting buckles 13, thus opening and closing the two connecting buckles 13. The connecting buckles 13 can be inserted into the connecting slot 6a, and the hook can hook into the connecting slot 6a to prevent the connecting buckles 13 from coming out.

[0039] The base frame 4 includes a foot 7 located at the bottom, and bolt holes 8 for anchor bolts 9 to pass through are provided on the foot 7. The lower end of the foot 7 is also provided with casters 10, which facilitate the movement of the fireproof and explosion-proof wall.

[0040] The fixed frame 1 is also provided with a diagonal brace assembly 3, such as Figure 9As shown, the diagonal brace assembly 3 includes a diagonal brace 23 hinged to the fixed frame 1. The diagonal brace 23 is located on the back side of the explosion surface. The upper end of the diagonal brace 23 is hinged to the hinge lug 12 on the fixed frame 1 through the hinge shaft 172, and the lower end is hinged to the bolt seat 24. The bolt seat 24 can also be fixed to the ground by the anchor bolt 9.

[0041] like Figure 6-8 As shown, the fireproof energy-absorbing module 2 includes a bladder 18, a fire extinguishing agent located inside the bladder 18, and a mounting base 19. The bladder 18 can be made of fireproof and environmentally friendly rubber material and is mounted on the mounting base 19. The fire extinguishing agent can be a solid fire extinguishing agent or a liquid fire extinguishing agent, such as sodium bicarbonate solution. When heated, it can decompose to produce gas, increasing the pressure inside the bladder and causing it to rupture, thus providing fire protection even in an environment without the possibility of explosion. A mounting groove 11 is provided on the fixed frame 1, and the mounting base 19 is fixed within the mounting groove 11.

[0042] In this embodiment, a window 110 is provided at the bottom of the mounting groove 11. A portion of the capsule 18 is located on the blast-facing side of the groove bottom, and another portion passes through the window 110 and is located on the non-blast-facing side of the groove bottom. The bottom of the mounting groove 11 is inclined, with the upper part of the groove bottom inclined towards the non-blast-facing side, so that the blast-facing side of the groove bottom faces upwards and the non-blast-facing side faces downwards. Multiple pressure relief grooves 21 are provided on the sidewall of the capsule 18. When the internal pressure of the capsule 18 exceeds a critical threshold, the pressure relief groove 21 ruptures. Preferably, the pressure relief grooves 21 can also be provided only on the sidewall of the portion of the capsule 18 located on the blast-facing side, so that the capsule 18 ruptures preferentially on the non-blast-facing side.

[0043] The capsule 18 includes a square mounting portion 181 and protrusions on both sides of the mounting portion. The mounting base 19 includes a box with an internal cavity. The mounting portion is located inside the box. Through holes 191 are provided on two opposite side walls of the box. The two protrusions pass through the two through holes 191 and protrude to the outside of the box. The protrusion on the blast-facing side is the first protrusion 182, and the protrusion on the blast-reversing side is the second protrusion 183. The outer diameter of the first protrusion 182 is larger than the outer diameter of the second protrusion 183. A latching seat 22 is provided on the side of the box near the bottom of the groove. A mounting hole is provided on the bottom of the groove. The latching seat 22 passes through the mounting hole and engages with the anti-detachment latch 20.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
