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.

[0048] 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.

[0049] This invention provides a dedicated fire suppression system for containers, such as... Figures 1-10 As shown, the container-specific fire suppression system includes:

[0050] A container 100 specifically designed for use in fire extinguishing systems for fireworks transportation includes a top plate 110 and a base 120. Four sets of vertically arranged sidewalls are provided between the top plate 110 and the base 120. The sidewall closest to the vehicle towing the container 100 is the front sidewall 130. Double doors are installed on the sidewall of the container 100 furthest from the front sidewall 130. The front sidewall 130 and the sidewall with the double doors are located on the short side of the container 100. The interior of the front sidewall 130 is hollow for storing equipment. The outer wall of the front sidewall 130 is designed with heat insulation and explosion-proof features to minimize the impact of fire on the internal equipment.

[0051] A sprinkler system 140 is suspended above the cargo holding area of ​​the container 100. The sprinkler system 140 includes a main pipe 141 and several sets of branch pipes 142 connected to the main pipe 141.

[0052] The extinguishing agent storage module 180 is also built into the front side wall 130. The extinguishing agent storage module 180 is a pressure vessel tank that mainly stores carbon dioxide extinguishing agent. The extinguishing agent storage module is connected to the sprinkler system 140 through pipelines. After a fire occurs, the extinguishing agent storage module 180 first provides carbon dioxide extinguishing agent to the container 100, and pushes the oxygen in the fire area out of the container 100 as soon as possible. The sealed environment of the container 100 makes it difficult for outside air to enter, thus blocking the combustion process.

[0053] A recycling and purification system for storing cooling water includes a recycling module and a purification water supply module installed at the bottom of the container 100. The recycling module is used to recycle the cooling water sprayed into the vehicle body, while the purification water supply module filters the cooling water and sends it back to the spray system 140.

[0054] Specifically, the recycling module includes a first collecting tank 101, a second collecting tank 102, and a collector 150 communicating with the first collecting tank 101 and the second collecting tank 102; the base 120 is located below the front side wall 130 and is also provided with a confluence tank 103 for communicating with the first collecting tank 101 and the second collecting tank 102, and the collector 150 is located in the middle section of the confluence tank 103.

[0055] The purified water supply module includes a pressure storage tank, a pressure tank 300, a filter element 400, and a water storage tank 500, all connected to a spray system 140. The water storage tank 500 is connected to a collector 150. The filter element 400 is installed on the pipeline connecting the water storage tank 500 and the pressure storage tank. The pressure tank 300 is connected to the water storage tank 500. The pressure storage tank, pressure tank 300, and filter element 400 are located on the front side wall 130. The water storage tank 500 is located inside the base 120. Under the pressure of the pressure tank 300, water in the water storage tank 500 is sent into the pressure storage tank. The water temporarily stored in the pressure storage tank is sprayed to the cargo holding area of ​​the container 100 via the spray system 140 at the rear of the pressure storage tank.

[0056] The collector 150 is provided with a drain pipe 1502 that connects to the water tank 500. The drain pipe 1502 is provided with a first control valve. During the recycling process, the first collection tank 101 and the second collection tank 102 directly collect the water in the collection tank, while the third confluence tank 103 guides the water from the first collection tank 101 and the second collection tank 102 into the collector 150. The water tank 500 serves as a temporary water storage area.

[0057] The pressure tank 300 will pressurize air into the water storage tank 500. During the air pressurization process, the first control valve of the drain pipe 1502 will cut off the connection between the water storage tank 500 and the collector 150. Under the pressure of the pressure tank 300, the water inside the water storage tank 500 will transport the recovered spray water to the filter element 400 and the pressure storage tank.

[0058] The pressure storage tank initially stores cooling water, which can be recycled and reused using a recycling and purification system. After the fire extinguishing agent storage module 180 initially releases the cooling water, it can promptly cool the interior of the container, thereby effectively controlling the internal temperature of the container. This application achieves an economic balance between the amount of cooling water carried and the carrying capacity by recycling the cooling water, reducing the empty weight of the vehicle during normal transportation while ensuring the corresponding condensation needs.

[0059] In a preferred embodiment of this invention, the water tank 500 includes a tank body and an outlet pipe 510 and an air inlet pipe 520 connected to the tank body. The pressure tank 300 is connected to the tank body through the air inlet pipe 520, and the tank body is connected to the filter element 400 through the outlet pipe 510.

[0060] In this embodiment, during actual use, the height of the end of the air inlet pipe 520 is higher than the liquid surface of the liquid stored in the tank, and the water outlet pipe 510 extends to the bottom of the liquid surface of the liquid stored in the tank. After the water tank 500 is disconnected from the outside, the air inlet pipe 520 will introduce the air in the pressure tank 300 into the water tank 500. Under the action of air pressure, the water in the water tank 500 will continue to flow to the filter device 400 and the pressure storage tank at the rear end. After entering the pressure storage tank, the water will be supplied to the spray system 140 by the pressure of the pressure storage tank itself.

[0061] As a preferred embodiment of this example, the pressure water storage tank includes a first pressure water storage tank 210 and a second pressure water storage tank 220, which are connected in parallel between the spray system 140 and the filter element 400.

[0062] In this embodiment, the first pressure water storage tank 210 is used as an example. Both the front and rear ends of the first pressure water storage tank 210 are equipped with flow control valves. The parallel structure design of the first pressure water storage tank 210 and the second pressure water storage tank 220 is mainly for alternating use to ensure that the terminal spraying action is not disturbed by the purification water supply action.

[0063] For example, the first pressure water storage tank 210 first opens the flow control valve connected to the spray system 140. After the cooling water filled in the first pressure water storage tank 210 is released, the first pressure water storage tank 210 closes the flow control valve connected to the spray system 140. Then the second pressure water storage tank 220 will release cooling water in place of the first pressure water storage tank 210. When the first pressure water storage tank 210 is replenishing water, the flow control valve connected to the spray system 140 needs to be closed, while the flow control valve between the first pressure water storage tank 210 and the filter element 400 needs to be opened. Under the pressure of the pressure tank 300, the cooling water inside the water storage tank 500 is forced into the first pressure water storage tank 210.

[0064] It should be noted that in addition to the flow control valve, a check valve is also installed on the pipeline between the first pressure water storage tank 210 and the filter element 400 to prevent the cooling water in the first pressure water storage tank 210 from flowing back.

[0065] In a preferred embodiment of this invention, the confluence channel 103 is arranged at the bottom of the front sidewall 130, the confluence channel 103 is opened on the base 120, and the collector 150 is provided with liquid collection pipes 1501 on both sides that communicate with the confluence channel 103.

[0066] In this embodiment, the collector 150 has a confluence area inside, and a drain pipe 1502 is provided at the center of the confluence area. The drain pipe 1502 leads to the water tank 500 located below the collector 150. The base 120 adopts a double-layer structure. The upper half adopts an integral structure, while the lower half adopts a hollow structure and is reinforced by a support frame. The hollow area of ​​the lower half is provided with a space to accommodate the water tank 500 on the side near the front sidewall 130.

[0067] The water storage tank 500 is located in the lower half of the layer and is lower than the upper half of the layer. The first collection tank 101 and the second collection tank 102 in the upper half of the layer, which are used to collect spray water, are higher than the water storage tank 500. The cooling water in the first collection tank 101 and the second collection tank 102 will enter the water storage tank 500 under its own weight. The water storage tank 500 can be used as a temporary storage area and, together with the drain pipe 1502, isolates the external environment. Thus, the air pressure of the pressure tank 300 is used to complete the water supply and purification operation into the pressure water storage tank.

[0068] The first collecting tank 101 and the second collecting tank 102 are also provided with a partition 160. The partition 160 is provided with a screen with a large aperture, mainly to help block large particles generated during the combustion process from entering the water storage tank 500. The converging tank 103 is located on both sides of the collector 150 and is also provided with a filter screen structure for blocking impurities.

[0069] In a preferred embodiment of this invention, the pressure tank 300 is replenished with gas using the air compressor of the semi-trailer truck tractor 100. An intake control valve 202 is installed at the intake end of the pressure tank 300. The intake control valve 202 is a three-way control valve, capable of depressurization and pressurization. The pressure tank 300 can be depressurized via the intake control valve 202. One end of the intake control valve 202 is connected to the pressure tank 300, and the other end is connected to the air compressor of the semi-trailer truck via a pipeline. An additional air outlet pipeline is installed at the air compressor of the semi-trailer truck, which automatically replenishes and pressurizes the pressure tank 300 when the pressure is insufficient.

[0070] The pressure tank 300 is equipped with an air supply control valve 201 in its air outlet pipe. The pressure tank 300 will close the air supply control valve 201 during the process of recycling cooling water in the water storage tank 500 to prevent cooling water from being unable to enter the water storage tank 500 due to air pressure. The water storage tank 500 is also equipped with a pressure relief pipe. After the pressure tank 300 pressurizes the water storage tank 500 and the water storage tank 500 completes the water supply operation to the pressure storage tank, the air supply control valve 201 will cut off the pressurization to the water storage tank 500. The water storage tank 500 will release pressure through the pressure relief pipe, so that the cooling water in the first collection tank 101 and the second collection tank 102 can be recycled after the drain pipe 1502 is opened.

[0071] In a further preferred embodiment of the present invention, the filter element 400 adopts the existing water purifier structure design; the filter element 400 is provided with at least three filtration mechanisms, namely a first filtration chamber 410, a second filtration chamber 420, and a third filtration chamber 430; the first filtration chamber 410, the second filtration chamber 420, and the third filtration chamber 430 are respectively filled with PP cotton filter element, activated carbon filter element, and activated carbon filter element; the PP cotton filter element, activated carbon filter element, and activated carbon filter element are used to filter large particulate impurities in the cooling water, so as to avoid the pipes or nozzles of the spray system 140 being blocked;

[0072] In this embodiment, the filter element 400 can refer to the filter mechanism design of existing household water purifiers. The front side wall 130 and the inner end face of the container 100 are provided with a flip-top door 170. The flip-top door 170 can communicate with the interior of the front side wall 130. The filter element 400 can communicate with the outside through the flip-top door 170, which facilitates the maintenance and replacement of the filter element in the filter element 400.

[0073] The operating steps for the dedicated container fire suppression system are as follows:

[0074] Step 1: After the fire detection device on the top of the container 100 detects the fire, the fire extinguishing agent storage module 180 provides carbon dioxide fire extinguishing agent to the sprinkler system 140 for initial fire extinguishing.

[0075] Step 2: When the temperature inside container 100 is at a dangerous level, the first pressure water tank 210 or the second pressure water tank 220 will provide cooling water to the spray system 140 for cooling. The cooling water falling from the spray will flow back to the water tank 500 through the first collection tank 101 and the second collection tank 102.

[0076] Step 3: After the cooling water is delivered from the first set of pressure storage tanks, another set of pressure storage tanks will take over from the first set to continue the water delivery operation. The cooling water in the storage tank 500 will be sent into the first set of pressure storage tanks under the pressure of the pressure tank 300.

[0077] The specific method is as follows: the drain pipe 1502 cuts off the internal connection between the water storage tank 500 and the container 100, the pressure tank 300 pressurizes the water storage tank 500, and at the same time the inlet of the first pressure water storage tank 210 or the second pressure water storage tank 220 is opened, so that the water storage tank 500 is refilled into the first pressure water storage tank 210 or the second pressure water storage tank 220 under pressure.

[0078] Step 4: While the first set of pressure water storage tanks is storing water, the second set of pressure water storage tanks continues to supply cooling water for spraying operations. Once the cooling water in the second set of pressure water storage tanks is used up, the first set of pressure water storage tanks takes over the water supply from the second set of pressure water storage tanks, and the second set enters the water replenishment process. The cooling water is used alternately in a cycle until the cooling water temperature rises and no longer meets the cooling requirements or the fire is brought under control and the process is automatically stopped.

[0079] In this application, the first pressure water storage tank 210, the second pressure water storage tank 220 and the water tank 500 are equipped with pressure sensors, liquid level sensors and water temperature sensors to help the system perform automatic state switching. The power of the corresponding equipment is provided by the semi-trailer tractor truck.

[0080] A fire extinguishing nozzle, characterized in that the fire extinguishing nozzle is applied to the container fire extinguishing system as described in claim 8, the fire extinguishing nozzle is installed on the spray system 140, the fire extinguishing nozzle is connected to the recovery and purification system and the fire extinguishing agent storage module 180 through pipelines respectively, and the fire extinguishing nozzle can meet the spraying operation of both carbon dioxide fire extinguishing agent and cooling water fire extinguishing agent.

[0081] The specific method is as follows: the sprinkler system 140 includes a main pipe 141 and several sets of branch pipes 142 connected to the main pipe 141. The fire extinguishing nozzles include gas nozzles and high-pressure nozzles. On the branch pipes 142 of different types of fire extinguishing nozzles, only the same type of gas nozzle or high-pressure nozzle is installed on the same pipe. When carbon dioxide is sprayed, the control valve of the branch pipe 142 with the gas nozzle is opened and connected to the main pipe 141. When water is sprayed for cooling, the control valve of the branch pipe 142 with the high-pressure nozzle is opened and connected to the main pipe 141. The two types of nozzles are used independently in different stages. The high-pressure nozzle and the gas nozzle are both existing technologies and utilize pressure-type single-fluid structure nozzles.

[0082] The fire extinguishing nozzles are directed toward the cargo holding area of ​​container 100.
