Description

Technical Field

[0001] This invention belongs to the field of modular housing technology, and relates to a protective device and process based on a fireworks modular housing. Background Technology

[0002] Fireworks, as a traditional festive item, are classified as flammable and explosive hazardous materials explicitly controlled under the "List of Hazardous Chemicals" and the "Regulations on the Safety Management of Fireworks and Firecrackers." They contain highly sensitive pyrotechnic agents, characterized by low ignition energy, rapid combustion propagation, and a strong explosive impact. Currently, some small and medium-sized fireworks and firecracker retailers use modular "prefabricated houses" for on-site sales—temporary or semi-permanent sales locations constructed from quick-assembly materials such as light steel frames and sandwich panels. While these prefabricated houses offer advantages such as short construction periods, low costs, and mobility, they generally suffer from problems such as inadequate fire separation, insufficient fire resistance ratings, lack of ventilation and explosion-proof design, and inadequate electrical explosion-proof measures.

[0003] In practice, although relevant regulations require prefabricated fire extinguishers and fire blankets to be equipped with basic fire-fighting equipment, factors such as poor space sealing, dense stacking of goods, and narrow safety passages mean that if a single firework is accidentally ignited due to static electricity, high temperature, mechanical impact, or human error, it can easily trigger a chain reaction of thermal radiation ignition and detonation propagation. The flames can cross adjacent shelves within seconds, and the superimposed reflection of the deflagration wave from the pyrotechnic agents will significantly amplify the pressure peak, causing the entire prefabricated fire extinguisher to explode within a very short time. This process not only causes total loss of property for the operator, but also, due to the lack of effective physical isolation and active explosion suppression measures, can easily affect adjacent buildings, pedestrians, and public facilities, leading to a major public safety accident with mass casualties. Summary of the Invention

[0006] Each gravity bar has a gravity block on its upper side, and each gravity block has a locking ring at its upper end. Each shelf compartment has an electromagnetic lock mechanism that cooperates with the locking ring at its top. The top of the assembly room is equipped with a smart camera facing the storage shelf.

[0007] The present invention is further configured such that each explosion-proof strip and each gravity strip is provided with a sliding shaft extending into and slidably connected to the corresponding inverted L-shaped slide rail at both ends.

[0008] The present invention is further configured such that the electromagnetic lock mechanism includes an electromagnet installed on the top of the corresponding shelf compartment, each electromagnet having a locking bar slidably connected to the end facing the opening of the corresponding shelf compartment, each locking bar having a magnetically attracted metal piece at the end facing the corresponding electromagnet, each electromagnet having sliding collars on both sides of the end facing the corresponding locking bar, each metal piece having a connecting slide shaft on both sides of the connecting slide shaft that cooperates with the corresponding sliding collar, each connecting slide shaft having a limit cap at the end passing through the corresponding sliding collar, and each connecting slide shaft having a supporting spring located between the corresponding metal piece and the corresponding sliding collar.

[0009] The invention is further configured such that the lower edge of each lock bar away from the corresponding metal piece is chamfered to form an inclined push opening.

[0010] The present invention is further configured such that each shelf compartment has a housing on its top, and each electromagnetic lock mechanism is disposed within the corresponding housing.

[0011] The present invention is further configured such that each protective curtain has a push bar provided downward on the side away from the corresponding gravity bar.

[0012] The invention is further configured such that a linear motor is installed on the top of the assembly room, a mover is provided on the linear motor, a U-shaped rotating frame is provided at the lower end of the mover, a hollow nozzle is rotatably connected inside the U-shaped rotating frame, a drive motor for driving the nozzle to rotate is installed on the U-shaped rotating frame, a fire extinguishing spray pipe is connected to the nozzle outward, a rotating connecting head is provided on one side of the U-shaped rotating frame, a rotating pipe is connected to the nozzle on one side and is sealed and rotatably connected to it, a solenoid valve is provided on the rotating connecting head, a fire extinguisher is provided in the assembly room, and the outlet end of the fire extinguisher is connected to the rotating connecting head through a guide pipe.

[0015] This invention also discloses a protective process for a fireworks assembly room. Using the aforementioned protective device based on a fireworks assembly room, the intelligent camera monitors the status of the fireworks inside the storage shelf in real time. When placing fireworks in the shelf compartment, the protective curtain is first pushed inward to the top of the shelf compartment. If a fire is detected burning in a shelf compartment, the electromagnetic lock mechanism at the corresponding position is immediately activated, causing the locking ring at the corresponding position to lose its fixation. Under the gravity of the gravity bar, the protective curtain is pulled downward to cover the opening of the corresponding shelf compartment, preventing the sparks from the fireworks inside from spreading outward and preventing the fireworks in the surrounding shelf compartments from being ignited.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Firstly, this invention uses a smart camera to monitor the status of fireworks in each shelf compartment of the assembly room in real time. When fireworks in a single shelf compartment accidentally ignite, the protective curtain can be unlocked through an electromagnetic lock mechanism. The protective curtain, composed of multiple hinged explosion-proof strips, is automatically lowered by gravity, quickly sealing the opening of the burning shelf compartment and forming the first physical barrier. This effectively blocks the outward spread of sparks and heat radiation, preventing fireworks in adjacent shelf compartments from being ignited and preventing chain explosions from occurring at the source.

[0018] Secondly, the present invention is also equipped with a movable and rotating fire extinguishing nozzle. After the fire area is sealed off by the protective curtain, the horizontal position of the nozzle can be adjusted by a linear motor, and the rotation angle of the nozzle can be adjusted to aim at the opening of the fire rack, spraying fire extinguishing agent to suppress or even extinguish the fire, further improving the protective effect.

[0025] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the protective device and process based on a fireworks assembly booth proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of this invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0026] Example, refer to Figure 1-5 A protective device based on a fireworks assembly room 1 includes the assembly room 1, with a storage shelf 2 installed on the inner wall of the assembly room 1. The storage shelf 2 has multiple shelf compartments 3. Each shelf compartment 3 has an inverted L-shaped slide rail 4 on both sides. Each inverted L-shaped slide rail 4 includes a horizontal section installed on the upper inner wall of the corresponding shelf compartment 3 and a vertical section installed at the opening end of the corresponding shelf compartment 3 and connected to the corresponding horizontal section. Each shelf compartment 3 is slidably connected to a protective curtain via the two inverted L-shaped slide rails 4. Each protective curtain is composed of multiple explosion-proof strips 5 hinged together end to end. Each protective curtain extends out of the corresponding shelf compartment 3 and has a gravity strip 6. Each explosion-proof strip 5 and each gravity strip 6 has a sliding shaft 7 that extends into and slidably connects to the corresponding inverted L-shaped slide rail 4. Each protective curtain has a pusher 8 on the side away from the corresponding gravity strip 6 to facilitate pushing the protective curtain inward.

[0027] Each gravity bar 6 has a gravity block 9 on its upper side, and each gravity block 9 has a locking ring 10 at its upper end. Each shelf compartment 3 has a housing 11 on its top, and each housing 11 has an electromagnetic lock mechanism that cooperates with the locking ring 10. The electromagnetic lock mechanism includes an electromagnet 12 installed on the top of the corresponding shelf compartment 3. Each electromagnet 12 has a locking bar 13 that cooperates with the corresponding locking ring 10 at the end facing the opening of the corresponding shelf compartment 3. The lower edge of each locking bar 13 away from the corresponding metal piece 14 is beveled to form an inclined push opening, which makes it easy for the locking ring 10 to push the locking bar 13 upward to retract inward. Each locking bar 13 has a magnetically attracted metal plate 14 at one end facing the corresponding electromagnet 12. Each electromagnet 12 has a sliding collar 15 on both sides of its corresponding locking bar 13 end. Each metal plate 14 has a connecting slide shaft 16 extending outwards from both sides, cooperating with the corresponding sliding collar 15. Each connecting slide shaft 16 has a limiting cap (not shown) at one end passing through the corresponding sliding collar 15. Each connecting slide shaft 16 is fitted with a supporting spring 17 located between the corresponding metal plate 14 and the corresponding sliding collar 15. When the electromagnet 12 is energized and attracts the metal plate 14, it drives the locking bar 13 to retract inwards, no longer locking the locking collar 10. Under the influence of gravity, the fixed gravity bar 6 pulls the protective curtain downwards, covering the opening of the shelf compartment 3.

[0028] Multiple smart cameras 18 facing the storage shelf 2 are installed on the ceiling of the assembly room 1. The smart cameras 18 monitor the fireworks status inside the storage shelf 2 in real time. A linear motor 19 is installed on the ceiling of the assembly room 1. A mover 20 is installed on the linear motor 19. A U-shaped rotating frame 21 is installed at the lower end of the mover 20. A hollow nozzle 22 is rotatably connected inside the U-shaped rotating frame 21. A drive motor 23 is installed on the U-shaped rotating frame 21 to drive the nozzle 22 to rotate. A worm gear 24 is installed around the nozzle 22. The power output shaft of the drive motor 23 is connected to a worm 25 that meshes with the worm gear 24. The drive motor 23 can drive the nozzle 22 to rotate back and forth. A fire extinguishing nozzle 26 is connected to the nozzle 22. A rotating connector 27 is installed on one side of the U-shaped rotating frame 21. A rotating pipe 28 extends into the rotating connector 27 and is rotatably connected to it. A solenoid valve 29 is installed on the rotating connector 27. A fire extinguisher 30 is installed inside the assembly room 1. The outlet end of the fire extinguisher 30 is connected to the rotating connector 27 via a guide pipe. A cable chain movable frame 31 is installed on the top of the assembly room 1. A cable chain 32 is connected inside the cable chain movable frame 31. The free end of the cable chain 32 is connected to the U-shaped rotating frame 21. The guide pipe includes a fixed pipe 33 fixed to the inner wall of the assembly room 1 and a movable flexible hose 34 installed inside the cable chain 32. If an external fire source is detected, according to the location of the fire source, the linear motor 19 first drives the fire extinguishing nozzle 26 to move to a position close to the fire source. The drive motor 23 drives the fire extinguishing nozzle 26 to rotate to face the fire source. After the solenoid valve 29 opens, the fire can be sprayed to extinguish the fire.

[0029] Protective technology for fireworks assembly room 1:

[0030] When using the aforementioned protective device, the intelligent camera 18 first monitors the fireworks in each shelf compartment 3 in real time. During the process of placing fireworks in the shelf compartment 3, the protective curtain is pushed upward along the inverted L-shaped slide rail 4 so that the protective curtain is completely stored at the top horizontal section of the shelf compartment 3. When the gravity block 9 moves to the top of the shelf compartment 3, the locking ring 10 will push open the inclined push port to retract the locking bar 13. After the locking ring 10 passes the locking bar 13, the support spring 17 pushes the locking bar 13 to reset and extend, locking the locking ring 10 to complete the locking, so that the protective curtain remains in the stored state and does not affect the taking and placing of fireworks.

[0031] If the smart camera 18 detects abnormal combustion of fireworks in a certain shelf compartment 3, the control system immediately cuts off the power supply to the electromagnet 12 of the electromagnetic lock mechanism of the corresponding shelf compartment 3. The electromagnet 12 loses its attraction to the metal plate 14, and the support spring 17 pushes the locking bar 13 to move outward and exit the locking ring 10. After the locking ring 10 is no longer limited by the locking bar 13, the gravity bar 6 slides down along the vertical section of the inverted L-shaped slide rail 4 under its own gravity, pulling the protective curtain composed of multiple hinged explosion-proof bars 5 to unfold downward, completely covering the opening of the corresponding shelf compartment 3. The explosion-proof bars 5 block the sparks and shock waves generated by the fireworks inside the shelf compartment 3 from spreading outward, preventing the fireworks in the surrounding shelf compartments 3 from igniting, and completing the physical isolation of the initial fire source.

[0032] If the smart camera 18 detects a fire source on the shelf 2, the control system drives the linear motor 19 to move the actuator 20, causing the nozzle 22 to move to the opening of the burning shelf compartment 3. At the same time, through the drive motor 23 and the worm gear 24 and worm 25, the spray angle of the nozzle 22 is adjusted to align with the fire point. Then, the solenoid valve 29 is opened, and the extinguishing medium in the fire extinguisher 30 is sprayed out through the guide tube, rotating connector 27, rotating tube 28 and nozzle 22, aiming at the fire point to extinguish the fire, further controlling the danger and preventing the fire from spreading.

[0033] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
