Description

Technical Field

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

[0002] During ship operation, the ship's cabin, as a core functional area, has an extremely complex internal spatial structure. It not only houses numerous precision equipment but also stores various flammable materials, such as fuel oil, lubricating oil, and cable insulation materials. These factors make the ship's cabin a high-risk area for fire accidents. Once a fire occurs, if it cannot be controlled in a timely and effective manner, it will spread rapidly, posing a huge threat to the safe navigation of the ship, the lives of personnel, and the cargo.

[0003] Currently, most traditional marine fire extinguishing systems employ a single extinguishing mode, failing to provide targeted treatment based on the size of the fire. In actual fire scenarios on board ships, the scale of fires varies significantly across different areas. Initially, it may be just a small fire caused by a minor electrical fault. Using a large-scale fire extinguishing system at this stage would not only result in a significant waste of fire extinguishing resources but could also damage equipment inside the ship due to excessive use of extinguishing agents. Furthermore, if a small fire is not controlled in time and gradually spreads into a large fire, a single fire extinguishing system may be unable to effectively contain the fire due to limited fire extinguishing capacity or untimely response, leading to further deterioration of the fire and missing the optimal fire extinguishing opportunity. This not only increases the difficulty and cost of fire extinguishing but also seriously threatens the lives of personnel inside the ship, causing huge losses to ship operations. Therefore, it is necessary to design a marine cabin fire extinguishing system. Utility Model Content

[0004] The purpose of this invention is to provide a marine cabin fire extinguishing device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A marine cabin fire extinguishing device includes an outer shell, which is a hollow shell. A partition is provided inside the outer shell to divide the interior of the outer shell into an upper chamber and a lower chamber. A first fire extinguishing system is provided in the upper chamber, and a second fire extinguishing system is provided in the lower chamber. The second fire extinguishing system is for extinguishing small fires, while the first fire extinguishing system and the second fire extinguishing system are for extinguishing large fires.

[0007] By adopting the above technical solution, because the internal space structure of the ship's cabin is complex, with many pieces of equipment and a large amount of combustibles, the scale of fires in different areas of the cabin will vary. Therefore, this fire extinguishing device adopts a graded fire extinguishing function. For small-scale initial fires, such as flames caused by minor electrical faults, the second fire extinguishing system will extinguish the fire in time to control the fire and prevent it from spreading into a large fire. When the fire spreads to the triggering mechanism of the first fire extinguishing system, the first fire extinguishing system will also be activated to participate in the fire extinguishing work, thereby saving fire extinguishing resources and promptly reminding personnel in the cabin to evacuate.

[0008] In a further embodiment, the second fire extinguishing system includes a baffle plate, a blasting shell, and a thermal wire. Two thermal wires are provided. The baffle plate separates the lower chamber into a left chamber and a right chamber, which are independent of each other. Each right chamber and left chamber is provided with a blasting shell and a jet nozzle. One end of the thermal wire is located on the outside of the shell, and the other end of the thermal wire passes through the outer shell and communicates with the corresponding blasting shell.

[0009] In a further embodiment, both the left and right chambers are provided with extinguishing agents, the blasting shell is a sealed bag, and the interior of the blasting shell is filled with a gas-generating agent.

[0010] By adopting the above technical solution, the heat-sensitive wire is connected to the flammable areas inside the cabin. When the temperature inside the cabin reaches the combustion temperature of the heat-sensitive wire, the heat-sensitive wire will burn rapidly and burn through the explosive shell in the lower chamber. This causes the gas-generating agent and the extinguishing agent to react chemically to produce the extinguishing medium. During this process, the pressure in both the right and left chambers will increase, thereby causing the extinguishing medium to be ejected from the nozzle. The design of the left and right chambers is to enable the lower chamber to extinguish fires simultaneously from both ends, thereby increasing the extinguishing area. Furthermore, the area and arrangement of the left and right chambers are consistent to ensure that both ends can respond synchronously in the event of a fire, quickly and effectively controlling the spread of the fire.

[0011] In a further embodiment, both the left and right chambers are provided with cooling chambers, which are located at the end near the jet nozzle, and the interior of the cooling chambers is provided with coolant.

[0012] By adopting the above technical solution, the coolant cools the extinguishing medium before it is sprayed from the nozzle, thus preventing it from becoming ineffective due to high temperature during the spraying process and extending its effective time in the fire.

[0013] In a further embodiment, the first fire extinguishing system includes a high-pressure fire extinguishing bottle, a first temperature sensor, a second temperature sensor, a first buzzer, a second buzzer, a smoke sensor, and a control box. The control box contains a control circuit board. The first temperature sensor, the second temperature sensor, the first buzzer, the second buzzer, and the smoke sensor are all wiredly connected to the control circuit board. Multiple high-pressure fire extinguishing bottles are detachably installed in the upper chamber. One end of the high-pressure fire extinguishing bottle is connected to a release tube, and the other end of the release tube is connected to a release connector. The release connector passes through the side wall of the housing and communicates with the outside of the housing. The first temperature sensor, the second temperature sensor, the first buzzer, the second buzzer, the smoke sensor, and the control box are all fixedly installed on the top of the housing.

[0014] By adopting the above technical solution, the alarm sounds of the first buzzer and the second buzzer are not consistent, and the trigger thresholds set internally by the first temperature sensor and the second temperature sensor are also inconsistent. The trigger threshold of the first temperature sensor is greater than that of the second temperature sensor. When the second temperature sensor detects the temperature of the burning thermal wire, it will trigger the internally set temperature threshold and then transmit the signal to the control circuit board. The control circuit board will then transmit the information to the second buzzer, causing the second buzzer to sound an alarm and reminding the people in the cabin to evacuate immediately. When the fire in the cabin becomes larger and the temperature continues to rise, smoke will continue to be generated, triggering the first temperature sensor and the smoke sensor to act simultaneously. After the control circuit board receives the abnormal signals from the first temperature sensor and the smoke sensor at the same time, it will control the high-pressure fire extinguisher to spray fire extinguishing material and simultaneously transmit the abnormal information to the first buzzer, causing the first buzzer to sound an alarm.

[0015] In a further embodiment, each of the top two ends of the outer casing is provided with an ear plate, and the ear plate is provided with positioning holes.

[0016] By adopting the above technical solution, the positioning hole makes it easy for operators to install this fire extinguishing device in a fire-prone area inside the ship's cabin.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By setting up different primary and secondary fire suppression systems, appropriate fire suppression measures can be taken for small and large fires respectively. In the small fire stage, the fire can be controlled in time to prevent it from spreading into a large fire. When the fire expands, the large fire suppression system can quickly intervene, thereby improving fire suppression efficiency, saving fire suppression resources, ensuring ship safety, and timely reminding personnel in the cabin to evacuate.

[0026] Example 1:

[0027] like Figures 1-4 As shown, a marine cabin fire extinguishing device includes an outer shell 1, which is a hollow shell. A partition 2 is provided inside the outer shell 1, which divides the interior of the outer shell 1 into an upper chamber 3 and a lower chamber 4. A first fire extinguishing system 5 is provided in the upper chamber 3, and a second fire extinguishing system 6 is provided in the lower chamber 4. The second fire extinguishing system 6 is for extinguishing small fires, while the first fire extinguishing system 5 and the second fire extinguishing system 6 are for extinguishing large fires.

[0028] The second fire extinguishing system 6 includes a baffle plate 61, a blasting casing 62, and a thermal wire 63. Two thermal wires 63 are provided. The baffle plate 61 divides the lower chamber 4 into two independent chambers, a left chamber 65 and a right chamber 64. Each chamber 64 and each left chamber 65 contains a blasting casing 62 and a jet nozzle. One end of the thermal wire 63 is located on the outside of the casing, and the other end passes through the outer shell 1 and connects to the corresponding blasting casing 62. Both the left chamber 65 and the right chamber 64 are equipped with extinguishing media. The blasting casing 62 is a sealed bag filled with a gas-generating agent. Both the left chamber 65 and the right chamber 64 are also equipped with a cooling chamber 66, located near the nozzle, and filled with coolant. The first fire extinguishing system 5 includes a high-pressure fire extinguishing cylinder 51, a first temperature sensor 52, a second temperature sensor 53, a first buzzer 54, a second buzzer 55, and a smoke generator. A fog sensor 57 and a control box 56 are included. The control box 56 contains a control circuit board. The first temperature sensor 52, the second temperature sensor 53, the first buzzer 54, the second buzzer 55, and the smoke sensor 57 are all wired to the control circuit board. Multiple high-pressure fire extinguishing bottles 51 are detachably installed in the upper chamber 3. One end of the high-pressure fire extinguishing bottle 51 is connected to a release tube, and the other end of the release tube is connected to a release connector. The release connector passes through the side wall of the shell and connects to the outside of the shell. The first temperature sensor 52, the second temperature sensor 53, the first buzzer 54, the second buzzer 55, the smoke sensor 57, and the control box 56 are all fixedly installed on the top of the outer shell 1. The bottom ends of the first temperature sensor 52, the second temperature sensor 53, the first buzzer 54, the second buzzer 55, the smoke sensor 57, and the control box 56 are all connected to the upper chamber for easy wire connection. An ear plate 7 is provided at both ends of the top of the outer shell 1, and the ear plate 7 is provided with positioning holes.

[0029] Specific implementation process: For small-scale initial fires, such as small flames caused by minor electrical faults, the second extinguishing system 6 of this fire extinguishing device takes effect first. One end of the heat-sensitive wire 63 is connected to the easily ignited part inside the compartment. When the temperature inside the compartment reaches the combustion temperature of the heat-sensitive wire 63, the heat-sensitive wire 63 burns rapidly and burns through the corresponding blasting shell 62 in the lower chamber 4. The blasting shell 62 is a sealed bag filled with a gas-generating agent. After it is ruptured, the gas-generating agent reacts chemically with the extinguishing agent in the left chamber 65 and the right chamber 64 to produce extinguishing media. Simultaneously, the reaction increases the pressure in the right chamber 64 and the left chamber 65, causing the extinguishing medium to be ejected from the nozzle. Furthermore, the design of the left chamber 65 and the right chamber 64 allows the second extinguishing system 6 to simultaneously extinguish fires from both ends, increasing the extinguishing area. The synchronized response at both ends rapidly controls the spread of fire. Before the extinguishing medium is ejected, the coolant in the cooling chamber 66 near the nozzle cools the medium, preventing it from failing due to high temperatures during spraying and prolonging its effective time in the fire. During this process, the second temperature sensor... The device 53 detects the burning temperature of the thermal wire 63, triggering the internally set temperature threshold and transmitting a signal to the control circuit board in the control box 56. The control circuit board then activates the second buzzer 55 to sound an alarm, reminding personnel in the cabin to evacuate immediately. If the small fire is not controlled in time and the fire spreads to the point of triggering the first fire extinguishing system 5, the first fire extinguishing system 5 will be activated immediately. At this time, the smoke sensor 57 detects smoke, and the temperature continues to rise, triggering the first temperature sensor 52 and the smoke sensor 57 to activate. The first temperature sensor 52 and the smoke sensor 57 simultaneously transmit abnormal signals to the control circuit board. The control circuit board, on the one hand, controls the high-pressure fire extinguishing bottle 51 in the upper chamber 3 to spray fire extinguishing material through the release pipe and release connector to extinguish the large fire; on the other hand, it transmits abnormal information to the first buzzer 54, causing the first buzzer 54 to sound an alarm, again emphasizing the severity of the fire and ensuring the safe evacuation of personnel. The entire fire extinguishing process is hierarchical and orderly, which can control small fires in time and effectively extinguish fires when they spread, ensuring the safety of the cabin and giving personnel in the cabin time to escape the fire scene.
