Description

Technical Field

[0001] This invention belongs to the field of container technology, and in particular relates to a mobile fireworks container with an explosion-proof device. Background Technology

[0002] Fireworks (firecrackers) are classified as Class 1 explosives, possessing highly dangerous characteristics such as flammability, explosiveness, and sensitivity to friction, impact, and high temperatures. Their transportation presents multiple safety risks. During transport, vehicle bumps, sudden braking, collisions, and compression can easily ignite the gunpowder inside the fireworks, potentially leading to a secondary explosion. High temperatures exacerbate the risks: in summer or under direct sunlight, the temperature inside the vehicle can rise, potentially igniting the gunpowder; illegally transported vehicles often lack temperature control and insulation measures.

[0003] A shipping container is a standardized large transport container used to load goods, facilitating mechanical loading and unloading and global logistics systems. Containers mainly rely on existing container trucks for transportation. However, in the field of fireworks transportation, designing a special high-safety fireworks transport vehicle is not only costly and impractical, but also has poor economic benefits. Currently, containers cannot directly carry fireworks in terms of safety. Therefore, there is a need for mobile containers that can be transported by container trucks and provide safety and explosion-proof performance. Summary of the Invention

[0007] An explosion-proof compartment is located on top of the storage area; the explosion-proof compartment includes a main tank for storing water and several sets of pressure relief structures; the storage area is equipped with a spray system, which is connected to the main tank.

[0008] The side partition includes an outer panel and a protective water tank embedded inside the outer panel. The protective water tank is connected to the main tank via a pipe.

[0009] The pressure relief structure includes a pressure relief chamber penetrating the explosion-proof compartment, a traction mechanism, and a pressure relief plate. The pressure relief plate is located at the bottom of the pressure relief chamber. The pressure relief chamber is connected to the main tank through a liquid inlet channel. The traction mechanism includes a buoyancy mechanism located inside the main tank and a sealing plug blocking the liquid inlet channel. The main tank releases water for cooling to the storage area through a spray system. As the water level in the main tank drops, the sealing plug disengages from the liquid inlet channel, and water in the main tank reaches the pressure relief chamber from the liquid inlet channel and is released into the storage area from the damaged pressure relief plate.

[0010] Preferably, the main body is provided with several sets of partition plates, which divide the main body into several sets of separate water storage areas. The number of water storage areas is the same as the number of storage areas, and the water storage areas are respectively set on the storage areas.

[0011] Preferably, at least one pressure relief structure is provided in the water storage area, and at least four traction mechanisms are provided around the pressure relief cavity.

[0012] Preferably, the buoyancy mechanism includes:

[0013] The floating cylinder is located in the water storage area of ​​the main tank.

[0014] A vertically sliding floating block, the floating block sliding inside a floating cylinder;

[0015] The traction rope has two ends connected to the floating block and the sealing plug respectively through a guide wheel assembly set in the water storage area. The floating block uses the traction rope to pull the horizontally moving sealing plug away from the liquid inlet channel.

[0016] Preferably, the top of the pressure relief chamber is also provided with an outer cover plate for sealing and maintenance.

[0017] Preferably, the main housing is provided with a stepped cylinder, the inner edge of the cylinder forms a pressure relief cavity, and the side wall of the cylinder is provided with a liquid inlet channel connecting the water storage area and the pressure relief cavity.

[0018] Preferably, the outer panel is hollow inside and communicates with the outside through an opening at the top of the outer panel. The protective water tank is embedded into the outer panel from the top of the opening. The protective water tank is provided with a connecting pipe, which communicates with the explosion-proof compartment.

[0019] Preferably, the protective water tank is provided with a support rod for support.

[0020] Preferably, each storage area is equipped with an independent spray system, and the spray system is connected to the water storage area above the storage area through a main inlet pipe.

[0021] Preferably, the spraying system includes:

[0022] The dispersion tubes are arranged in parallel and are connected by support rods.

[0023] The main inlet pipe is connected to one of the set of distribution pipes, and the end of the main inlet pipe away from the distribution pipe is connected to the inside of the main housing.

[0024] And the spray head located below the dispersion pipe.

[0025] Compared with the prior art, the embodiments of this application have the following main advantages:

[0026] 1. The fireworks mobile container with explosion-proof device provided by the present invention has water storage areas respectively set on the storage area, and the water storage area and the storage area are respectively connected in a one-to-one manner for treatment. Each storage area is independently equipped with a spray system, and the spray system is used to deal with the danger in time and ensure safety during transportation.

[0027] 2. The fireworks mobile container with explosion-proof device provided by this invention uses a pressure relief structure. The pressure relief structure uses a pressure relief plate and a pressure relief chamber to complete the initial pressure relief. The pressure relief plate is actively broken to release the pressure, allowing the impact generated during the explosion to be released towards the top of the explosion-proof compartment, reducing the impact force on the bottom plate, side partitions and other side walls. After the pressure relief plate is broken due to the explosion impact, water will be released directly into the storage area with the help of the traction mechanism to flush and pour out a large amount of fireworks in the storage area, achieving rapid cooling and timely containment of the risk of explosion and fire.

[0028] 3. The side partition of the fireworks mobile container with explosion-proof device provided by the present invention adopts a nested design of metal plate and protective water tank. Due to the function of the side partition, the entire loading area is formed into independent storage areas. The independent storage of the storage areas reduces the risk of violent explosions that may be caused, and avoids the chain reaction of concentrated storage of fireworks. The multi-layer structure enhances the impact resistance, and when the side partition is damaged under the impact of an explosion, the water in the protective water tank will be poured to the explosion side in time after the explosion, blocking and curbing the chain reaction, thereby ensuring the safety of the transportation process.

[0040] 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 application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0041] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0042] This invention provides a portable fireworks container with an explosion-proof device, such as... Figures 1-9 As shown, the fireworks mobile container with an explosion-proof device includes:

[0043] The system comprises a base plate 100, side partitions 200, and an explosion-proof compartment 300. The side partitions 200 are equidistantly spaced along the long side of the base plate 100 to form several isolated storage areas 101. The storage areas 101 are used to store fireworks. The explosion-proof compartment 300 is located on top of the storage areas 101. One side of the storage area 101 along the long side of the base plate 100 is equipped with an explosion-proof plate for sealing, and the other side is equipped with a double-opening side door 400. The structure of the base plate 100 is similar to that of an existing container base plate. When the side door 400 is opened, the storage area 101 is connected to the outside world, serving as a passage for fireworks to enter and exit.

[0044] The explosion-proof chamber 300 includes a main tank 310 for storing water and several sets of pressure relief structures. The storage area 101 is equipped with a spray system, which is connected to the main tank 310. The pressure relief structure includes a pressure relief chamber 302 penetrating the explosion-proof chamber 300, a traction mechanism 340, and a pressure relief plate 330. The pressure relief plate 330 is located at the bottom of the pressure relief chamber 302. The pressure relief chamber 302 is connected to the main tank 310 through a liquid inlet channel. The main tank 310 releases water for cooling into the storage area 101 through the spray system. As the water level in the main tank 310 drops, the seal 343 disengages from the liquid inlet channel 303, and water in the main tank 310 reaches the pressure relief chamber 302 from the liquid inlet channel.

[0045] The side partition 200 includes an outer panel 210 made of metal sheet and a protective water tank 220 embedded inside the outer panel 210. The outer panel 210 is hollow inside and communicates with the outside through an opening at the top of the outer panel 210. The protective water tank 220 is embedded into the outer panel 210 from the top of the opening. The protective water tank 220 is provided with a support rod 230 for support inside. The protective water tank 220 can be made of high-strength plastic material and uses the support rod 230 for support. The main tank 310 is made of corrosion-resistant high-strength stainless steel, and the inner wall used for water storage is coated with a waterproof and corrosion-resistant material to reduce the corrosion of the tank.

[0046] The side partition 200 adopts a nested design of metal sheet and protective water tank 220. Due to the function of the side partition 200, the entire loading area is divided into independent storage areas 101. The independent storage of storage areas 101 reduces the risk of violent explosions and avoids chain reactions caused by concentrated storage of fireworks. The multi-layer structure enhances the impact resistance. In addition, when the side partition 200 is damaged under the impact of an explosion, the water in the protective water tank 220 will be poured to the explosion side in time after the explosion, blocking and curbing the chain reaction.

[0047] The main body 310 is equipped with several sets of dividing plates 350. The main body 310 is divided into several sets of separate water storage areas 301 by the dividing plates 350. The number of water storage areas 301 is the same as the number of storage areas 101. The water storage areas 301 are respectively set on the storage areas 101. The water storage areas 301 and the storage areas 101 are respectively matched one-to-one for water storage. Each storage area 101 is independently equipped with a spray system. The spray system is connected to the water storage area 301 above the storage area 101 through the main inlet pipe 520.

[0048] In addition to traditional spraying methods, the explosion-proof chamber 300 is also equipped with a pressure relief structure. The pressure relief structure uses a pressure relief plate 330 and a pressure relief chamber 302 to complete the initial pressure relief. The pressure relief plate 330 is actively broken to release the pressure, allowing the impact generated during the explosion to be released towards the top of the explosion-proof chamber 300, reducing the impact force on the bottom plate 100, side partitions 200 and other side walls. The pressure relief plate 330 and the pressure relief chamber 302 absorb the impact generated by the primary explosion. The pressure relief plate 330 here is a mature structure with existing technology.

[0049] Meanwhile, the traction mechanism 340 set in the explosion-proof chamber 300 uses buoyancy to pull the sealing block 343 out of the liquid inlet channel 303. After the liquid inlet channel 303 connects the pressure relief chamber 302 and the water storage area 301, the water in the water storage area 301 will enter the pressure relief chamber 302 in advance. When the pressure relief plate 330 is broken due to the explosion impact, the water will be directly released into the storage area 101 to flush the fireworks in the storage area 101 in large quantities, so as to achieve rapid cooling.

[0050] As a preferred embodiment of this example, at least one set of pressure relief structures is provided in the water storage area 301, and at least four sets of traction mechanisms 340 are provided on the periphery of the pressure relief cavity 302.

[0051] In this embodiment, in order to accelerate the entry of water from the water storage area 301 into the pressure relief chamber 302, multiple sets of liquid inlet channels 303 are used to quickly replenish water, allowing water to enter the storage area 101 from the pressure relief chamber 302 with a larger diameter, and quickly deal with the safety risks in the storage area 101.

[0052] The pressure relief chamber 302 is constructed by directly welding a stepped cylinder into the main housing 310. The inner edge of the cylinder forms the pressure relief chamber 302. The side wall of the cylinder is provided with a liquid inlet channel 303 connecting the water storage area 301 and the pressure relief chamber 302. A support ring is provided on the inner side wall of the cylinder near the storage area 101. The pressure relief plate 330 is fixed to the support ring by a sealing ring and bolts. An outer cover plate 320 is provided on the top of the cylinder. The outer cover plate 320 is a circular flip-top plate pressed onto the top of the pressure relief chamber 302. The outer cover plate 320 normally serves as an inspection window. During explosion protection, it works with the pressure relief plate 330 to form a secondary impact resistance system, reducing the impact of explosion on the surrounding side walls and bottom.

[0053] In a preferred embodiment of this invention, the protective water tank 220 is provided with a connecting pipe, which is connected to the explosion-proof chamber 300 and inserted into the main tank 310.

[0054] The protective water tank 220 is equipped with a support rod 230 for support. Figure 7 This is a schematic diagram of the structure after one side of the protective water tank 220 has been removed. The protective water tank 220 is an integral cuboid structure, and the support rod 230 is installed inside the protective water tank 220.

[0055] The dividing plate 350 divides the main tank 310 into a water storage area 301. The dividing plate 350 has through holes, which are positioned near the top of the main tank 310. The bottom of the main tank 310 is also provided with a liquid outlet pipe for connecting to the spray system. It should be noted that a separate spray system is set up in each storage area 101. The spray system is connected to the water storage area 301 above the storage area 101 through the main inlet pipe 520. The top surface of the main tank 310 is provided with a water inlet, which can be a set. After the water is injected into the main tank 310, it is dispersed into the corresponding areas by the dividing plate 350 and the connecting pipe.

[0056] Generally, the bottom of the main enclosure 310 has a pre-set socket, which allows the connecting pipe to be inserted into the socket. Then, the main enclosure 310 and the outer panel 210 are sealed and welded together.

[0057] As a preferred embodiment of this invention, the spraying system includes:

[0058] The dispersion tube 510 is provided in at least three sets, arranged in parallel, and the dispersion tubes 510 are connected by support rods.

[0059] The main inlet pipe 520 is connected to one of the set of dispersion pipes 510, and the end of the main inlet pipe 520 away from the dispersion pipe 510 is connected to the inside of the main housing 310.

[0060] and a spray head located below the dispersion pipe 510.

[0061] In this embodiment, after water is injected into the water storage area 301, high-pressure air also needs to be added. High-pressure air can also be added from the water inlet. High-pressure air is used to enhance the spraying effect. A solenoid valve is set on the main inlet pipe 520 to control the spraying action of the water. It should be noted that a sensor head is set inside the storage area 101. This is mainly a temperature sensor and a pressure sensor. The solenoid valve receives the signals from the temperature sensor and the pressure sensor to operate.

[0062] The solenoid valve receives signals from the temperature and pressure sensors and works in conjunction with the sprinkler system. A single sprinkler system relies on the temperature and pressure sensors in that area to monitor the operation of storage area 101. The solenoid valve, temperature and pressure sensors are existing technologies. The solenoid valve, temperature and pressure sensors require little power and can be powered by dry batteries. There is no need to configure a power supply structure, which reduces the risk of fire caused by abnormal power supply systems.

[0063] In a preferred embodiment of this invention, the buoyancy mechanism includes:

[0064] The floating cylinder 342 is connected at its bottom to the water storage area 301 in the main body 310; the bottom of the floating cylinder 342 is provided with an opening to allow water to enter and exit, and the floating cylinder 342 is directly connected to the water storage area 301 at both the top and bottom.

[0065] A vertically sliding floating block 341 slides inside a floating cylinder 342. A limiting ring is provided at the top of the floating cylinder 342 to restrict the floating block 341 and prevent it from directly detaching from the cylinder. The floating block 341 has an internal cavity to provide buoyancy.

[0066] The traction rope has two ends connected to the floating block 341 and the sealing plug 343 respectively after passing through the guide wheel assembly set in the water storage area 301. The floating block 341 pulls the horizontally moving sealing plug 343 away from the liquid inlet channel 303 through the traction rope.

[0067] In this embodiment, the weight of the floating block 341 is equal to the product of the water density and its own volume. The floating block 341 is suspended in the water. The floating cylinder 342 contains the floating block 341, which can only move up and down. Due to the limitation of the limiting ring and the limited rising height, and under the traction of the sealing plug 343, the floating block 341 cannot easily move down. The main box 310 is provided with an inspection hole near the top of the floating cylinder 342. After the inspection hole is opened, the floating block 341 needs to be manually pulled up first, and then the sealing plug 343 needs to be used to block the liquid inlet channel 303 before water is injected. When the water level rises, the floating block 341 is suspended in the water under the action of buoyancy and will no longer easily pull out the sealing plug 343.

[0068] After the sprinkler system is activated, the water level in the water storage area 301 above the hazardous storage area 101 will drop until the buoyancy can no longer support the floating block 341. The weight of the floating block 341 will pull the sealing block 343 out of the liquid inlet channel 303, and the water will enter the pressure relief chamber to wait. It should be noted that when the traction rope is taut, the suspension height of the floating block 341 should be greater than the set height of the liquid inlet channel 303 to prevent the water storage area 301 from releasing water from the pressure relief chamber 302 to suppress the fire after the floating block 341 descends and opens. The suspension height of the floating block 341 should be slightly lower than the initial height of the water storage area 301.

[0069] The guide wheel assembly consists of two sets of rollers. To achieve the transmission of tension, the two sets of rollers are respectively set at the top and bottom of the main housing 310. When the traction rope is under tension, the connection section between the traction rope and the sealing plug 343 needs to be parallel to the direction of the sealing plug 343 being pulled out.

[0070] The working principle of this invention is as follows:

[0071] After the temperature and pressure sensors detect a fire risk signal in the storage area 101, the sprinkler system in the storage area 101 will promptly open the solenoid valve to supply water. The water in the water storage area 301 will be sprayed into the storage area 101 under the action of high pressure air. As the water level in the water storage area 301 drops, the traction mechanism 340 will release the water into the pressure relief chamber 302 in advance.

[0072] When the fire spreads rapidly and becomes uncontrollable, the pressure or initial internal explosion will damage the pressure relief plate 330. After the pressure relief plate 330 is damaged, the pressure relief chamber 302 will release the pressure into the pressure relief chamber 302. The pressure relief chamber 302 will also be used as a water release port. The large-diameter pressure relief chamber 302 will be used to quickly flush out a large amount of water in a short time to achieve rapid cooling and timely containment of the risk of explosion and fire.

[0073] If the fire cannot be contained in the water storage area 301 with the pressure relief structure, and the explosion continues in the storage area 101, the side partition 200 will be damaged during the impact. Since the outer plate 210 wraps the protective water tank 220, after one side of the outer plate 210 and the protective water tank 220 is damaged, the water in the protective water tank 220 will quickly pour out from the damaged area. When the side partition 200 is damaged under the impact of the explosion, the water in the protective water tank 220 will promptly pour to the explosion side after the explosion, blocking and curbing the chain reaction, thereby ensuring the safety of the transportation process.

[0074] The above-mentioned multi-level handling method improves the safety of containers used for transporting fireworks, utilizes the multi-level structure to handle emergencies in a timely manner, reduces the possibility of chain reactions caused by fireworks accidents, and uses the safety and explosion-proof performance of containers to provide safety guarantees for fireworks transportation; the above measures can also delay the deterioration of safety accidents during fireworks transportation to the greatest extent, buying time for disasters.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
