[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] like Figure 1 and Figure 2 As shown, the present invention proposes an intelligent cabin sprinkler system, comprising: a monitoring unit, a controller, a sprinkler fire extinguishing unit, and an alarm unit for installation inside the cabin; the monitoring unit includes a composite monitoring module for real-time monitoring of the cabin interior, and the composite monitoring module, the sprinkler fire extinguishing unit, and the alarm unit are electrically connected to the controller respectively.
[0027] The sprinkler fire suppression unit includes a sprinkler fire suppression host 1, a sprinkler pipe 3, multiple fixed sprinkler modules, multiple movable sprinkler modules, and multiple drive mechanisms. The sprinkler fire suppression host 1 is installed under the passenger seats. The sprinkler pipe 3 is installed on the inner wall of the passenger cabin roof along its length, and the sprinkler pipe 3 is connected to the sprinkler fire suppression host 1 via a pipe. The fixed sprinkler modules are evenly and spaced below the sprinkler pipe 3 along its axial direction, and the fixed sprinkler modules are connected to the sprinkler pipe 3. The multiple movable sprinkler modules are arranged one-to-one with the multiple fixed sprinkler modules, and the movable sprinkler modules can move closer to or away from the corresponding fixed sprinkler modules, and the movable sprinkler modules are connected to the sprinkler pipe 3. The multiple drive mechanisms are connected to the multiple movable sprinkler modules, and the drive mechanisms are used to drive the corresponding movable sprinkler modules to move closer to or away from the corresponding fixed sprinkler modules.
[0028] This invention first uses a composite monitoring module in the monitoring unit to monitor the cabin interior in real time and transmits various parameters obtained from the monitoring to the controller. The controller determines whether there is a fire inside the cabin based on the composite parameters. When a fire is detected, the controller instructs the alarm unit to sound an alarm, reminding passengers and the driver to evacuate immediately to avoid casualties. Subsequently, the controller activates the sprinkler fire extinguishing host 1 to spray extinguishing agent onto the fire point inside the cabin through the fixed sprinkler module, and simultaneously controls the active sprinkler module to activate and spray the fire point in a targeted manner. By using the limited extinguishing agent, the fire point is extinguished in a timely and targeted manner, which effectively improves the speed and efficiency of fire extinguishing, prevents the fire from spreading further, and effectively reduces the probability of reignition.
[0029] In this embodiment, the monitoring unit also includes a fire-fighting smart camera, which is electrically connected to the controller so that the back-end management personnel can monitor the fire situation in the cabin in real time, which is conducive to timely judgment and corresponding fire-fighting measures.
[0030] In practical applications, the monitoring unit, controller, sprinkler fire suppression unit, and alarm unit are all installed inside the passenger cabin. For example, the alarm unit includes multiple audible and visual alarms, which are installed at one or more locations in the passenger cabin, such as the driver's seat, the exit door in the middle of the passenger cabin, and the top surface at the rear of the passenger cabin, to warn the driver and passengers to evacuate quickly. For example, the sprinkler fire suppression main unit 1 is installed under the passenger cabin seats.
[0031] In one specific embodiment, the movable spray module may move closer to or further away from the corresponding fixed spray module in a direction perpendicular to the axial direction of the spray pipe 3.
[0032] Of course, in other specific embodiments, the angle between the direction in which the active spray module moves closer to or further away from the corresponding fixed spray module and the axis of the spray pipe 3 is an acute angle or an obtuse angle.
[0033] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the fixed spray module includes a diversion bar 4, a first diversion pipe 5, a first nozzle 6, and a first control valve 7. The diversion bar 4 is installed on the spray pipe 3 and communicates with the spray pipe 3. One end of the first diversion pipe 5 is connected to the diversion bar 4, and the other end is connected to the first nozzle 6. The nozzle of the first nozzle 6 is arranged with its nozzle facing downward. The first control valve 7 is installed on the first diversion pipe 5 and is electrically connected to the controller.
[0034] Specifically, the first branch pipe 5 is arranged vertically.
[0035] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the active spray module includes a second diversion pipe 8, a second nozzle 9, and a second control valve 10. One end of the second diversion pipe 8 is connected to the diversion row 4, and the other end is connected to the second nozzle 9. The nozzle of the second nozzle 9 is arranged downwards, and the second nozzle 9 is arranged on one side of the first nozzle 6. The second nozzle 9 can move closer to or further away from the corresponding first nozzle 6 relative to the corresponding first nozzle 6. The second control valve 10 is installed on the second diversion pipe 8 and is electrically connected to the controller.
[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the drive mechanism includes a motor 11, a one-way lead screw 12, a guide rod, and a connecting block 13. The one-way lead screw 12 is arranged on the inner wall of the cabin top along the direction of the movable spray module toward or away from the corresponding fixed spray module. The motor 11 is installed on the inner wall of the cabin top, and the output shaft of the motor 11 is coaxially and fixedly connected to the one-way lead screw 12. The guide rod is installed inside the cabin top and arranged parallel to the one-way lead screw 12. The connecting block 13 is screwed to the one-way lead screw 12 and slidably connected to the guide rod. The movable spray module is installed at the bottom of the connecting block 13. The motor 11 is electrically connected to the controller.
[0037] In practice, the second nozzle 9 of the active spray module is installed at the bottom of the connecting block 13. When the controller starts the motor 11, the output shaft of the motor 11 rotates, driving the one-way lead screw 12 to rotate, thereby driving the connecting block 13 to move forward or backward along the guide rod; the forward or backward movement of the connecting block 13 in turn drives the second nozzle 9, the box 14, and the second temperature sensor 22 to move synchronously. Since the first rack 19 meshes with the first gear 18 at the same time, the first gear 18 rotates, thereby driving the roller 15 to rotate, which in turn drives the protective cover connected to one end of the rope 16 to move downward or upward.
[0038] It should be noted that the one-way lead screw 12 in this embodiment specifically refers to a lead screw with only one type of thread, which is either a right-hand thread or a left-hand thread.
[0039] In a further embodiment, a second temperature sensor 22 is also installed on the connecting block 13. This arrangement allows the second temperature sensor 22 to move along with the movable spray module driven by the drive mechanism, facilitating accurate identification of the ignition point.
[0040] In a further embodiment, an automatic vertical adjustment mechanism is also included. The vertical adjustment mechanism is mounted on the connecting block 13, and the second temperature sensor 22 is mounted at the bottom of the automatic vertical adjustment mechanism. The automatic vertical adjustment mechanism is electrically connected to the controller. The vertical adjustment mechanism is used to drive the second temperature sensor 22 to move up and down in the vertical direction, so as to more accurately identify the location of the fire point, thereby facilitating targeted spraying of the fire point by the active spray module, thereby effectively improving the speed of fire extinguishing and reducing the range of fire combustion.
[0041] like Figure 5 As shown, in a further embodiment, a linkage vertical adjustment mechanism is also included. The linkage vertical adjustment mechanism includes a housing 14, a roller 15, a protective cover, a rope 16, a first gear 18, and a first rack 19. The housing 14 is installed on one side of the outer wall of the connecting block 13. The roller 15 is rotatably installed inside the housing 14, and the axis of the roller 15 is perpendicular to the axis of the one-way lead screw 12. The protective cover is arranged below the housing 14. One end of the rope 16 is wound around the roller 15, and the other end passes through the bottom of the housing 14 and is fixed to the protective cover. The second temperature sensor 22 is installed inside the protective cover. The first rack 19 is used to install on the interior of the cabin top wall on one side of the connecting block 13, and the first rack 19 is arranged parallel to the one-way lead screw. The first gear 18 is coaxially fixed with the roller 15, and the top of the first gear 18 extends to the top of the housing 14, and the first gear 18 meshes with the first rack 19.
[0042] In specific implementation, when the drive mechanism is working, the connecting block 13 moves axially along the one-way screw 12, driving the box body 14 to move axially along the one-way screw 12. During the movement of the box body 14, the first gear 18 rotates under the meshing action of the first rack 19, thereby driving the roller 15 to rotate. The rotation of the roller 15 drives the rope 16 to wind up and down, thereby driving the protective cover to move up and down, thereby driving the second temperature sensor 22 to move up and down. This facilitates the movement of the second temperature sensor 22 during the process of the drive mechanism driving the movable spray module to move, without the need for additional power. It can more accurately identify the location of the fire point, thus facilitating targeted spraying of the fire point through the movable spray module, thereby effectively improving the speed of fire extinguishing and reducing the range of fire combustion.
[0043] In a further embodiment, two guide blocks 25 are also included. The two guide blocks 25 are symmetrically fixed at the bottom of the box body 14, and the protective cover is located between the two guide blocks 25. The outer walls of the two sides of the protective cover are slidably connected to the two guide blocks 25 respectively.
[0044] In a further embodiment, the bottom end of the guide block 25 is provided with a guide slope, which is beneficial for automatically correcting and guiding the protective cover during the up-and-down movement of the protective cover.
[0045] In a further embodiment, the protective cover includes a cover body 17, a bidirectional lead screw 26, two sliders 20, two connecting rods 21, an adapter block 2, a second gear 23, and a second rack 24; the cover body 17 has an opening at its bottom; the bidirectional lead screw 26 is rotatably mounted inside the cover body 17, and the axial direction of the bidirectional lead screw 26 is parallel to the axial direction of the roller 15; the adapter block 2 is arranged inside the cover body 17 below the bidirectional lead screw 26, and the adapter block 2 is slidably connected to the cover body 17 in the vertical direction; two sliders are symmetrically arranged on the bidirectional lead screw 26, and the two... The sliders 20 are threadedly connected to the bidirectional lead screw 26, and the two sliders 20 can move towards each other or relative to each other when the bidirectional lead screw 26 rotates; one end of each of the two connecting rods 21 is hinged to the middle of the adapter block 2, and the other end is hinged to the two sliders 20 respectively; the second gear 23 is coaxially fixed on one end of the bidirectional lead screw 26; the second rack 24 is fixed vertically to the bottom of the box 14, and the second rack 24 penetrates the cover 17 and extends into the inside of the cover 17 to mesh with the second gear 23; the second temperature sensor 22 is installed at the bottom of the adapter block 2.
[0046] It should be noted that the bidirectional lead screw 26 in this embodiment specifically refers to a left-hand and right-hand lead screw. Half of the threaded portion of the left-hand and right-hand lead screw is a left-hand thread, and the other half is a right-hand thread. One of the two sliders 20 is threaded onto the left-hand thread, and the other is threaded onto the right-hand thread. When the left-hand and right-hand lead screws rotate in one direction, the two sliders 20 either separate or move closer together, i.e., move towards or relative to each other. When the left-hand and right-hand lead screws rotate in opposite directions, the two sliders 20 either move closer together or separate, i.e., move towards or relative to each other.
[0047] In this specific implementation, when the protective cover moves up and down, the second gear 23 rotates under the action of the second rack 24, thereby driving the bidirectional lead screw 26 to rotate. The rotation of the bidirectional lead screw 26 drives the two sliders 20 to move simultaneously towards or relative to each other, thereby causing the adapter block to slide up and down in the vertical direction. The sliding of the adapter block 2 up and down in the vertical direction drives the second temperature sensor 22 to move up and down, retracting into the cover 17 from the opening or extending out of the cover 17 from the opening. When the second temperature sensor 22 extends out of the cover 17 from the opening, it can be brought closer to the ignition point, thus making it easier for the second temperature sensor 22 to identify the ignition point.
[0048] In a further embodiment, a protective assembly is provided at the opening of the cover 17. The protective assembly includes two baffles 27, two slide rods 28, two springs 30, and two stops 29. The two baffles 27 are symmetrically arranged at the opening of the cover 17. A pair of guide surfaces forming a wedge structure are provided between the two baffles 27. The guide surfaces are matched with the bottom of the second temperature sensor 22. The two slide rods 28 are horizontally fixed on the two baffles 27 one by one. The other end of the two slide rods 28 passes through the cover 17 and extends outside the cover 17 to be fixedly connected to the two stops 29 one by one. The slide rods 28 are slidably connected to the cover 17. The two springs 30 are sleeved on the two slide rods 28 one by one and are located between the corresponding stops 29 and the cover 17.
[0049] This configuration transforms the vertical movement of the second temperature sensor 22 into the horizontal movement of the baffle 27. Specifically, when the second temperature sensor 22 moves downwards and comes into contact with the two guide surfaces, the two baffles 27 move apart under the vertical force of the second temperature sensor 22, allowing the second temperature sensor 22 to pass through the baffles 27 and extend out of the cover 17. When the second temperature sensor 22 moves back into the cover 17 from the opening, the baffles 27 reset under the rebound force of the spring 30. This embodiment utilizes a protective assembly to protect the second temperature sensor 22 when it is not in operation.
[0050] In this embodiment, there are multiple composite monitoring modules, which are installed sequentially along the length of the inner wall of the cabin roof to facilitate timely detection of fire.
[0051] Specifically, the number of composite detection modules is the same as the number of fixed spray modules, and multiple composite detection modules are installed one-to-one on the inner wall of the cabin top on one side of the diversion row 4 of multiple fixed spray modules.
[0052] In this further embodiment, the composite monitoring module includes a first temperature sensor, a smoke sensor, a CO sensor, a VOC sensor, and an infrared flame detector. The first temperature sensor, the smoke sensor, the CO sensor, the VOC sensor, and the infrared flame detector are electrically connected to the controller to facilitate accurate detection of thermal runaway.
[0053] In this embodiment, a background management unit is also included, which is electrically connected to the controller.
[0054] With this configuration, the controller will transmit the various parameters it receives and the corresponding instructions it issues to the back-end management unit, making it convenient for back-end administrators to perform remote operations.
[0055] Specifically, the back-end management unit includes a video display module, a data storage module, and a data processing module. The video display module, the back-end data storage module, and the back-end data processing module are electrically connected to the controller, and the back-end data storage module and the back-end data processing module are electrically connected.
[0056] With this setup, the background data processing module can process the data stored in the background data storage module and send the corresponding instructions to the controller, which then controls the sprinkler fire extinguishing host 1 and the drive mechanism to perform actions.
[0057] The present invention also proposes a public transportation vehicle, including a vehicle body with a passenger cabin, characterized in that the passenger cabin is equipped with a passenger cabin intelligent sprinkler system as described in any of the above.
[0058] In this embodiment, the public transportation vehicle includes the cabin intelligent sprinkler system described in any of the above embodiments, and therefore has all the beneficial effects of the cabin intelligent sprinkler system, which will not be repeated here.
[0059] In its specific operation, the present invention first monitors the interior of the cabin in real time through the composite monitoring module in the monitoring unit. The composite monitoring module acquires various parameters through a first temperature sensor, smoke sensor, CO sensor, VOC sensor and infrared flame detector, and transmits the various parameters to the controller.
[0060] The controller determines whether there is a fire inside the cabin based on a combination of multiple parameters. When a fire is detected inside the cabin, the controller instructs the alarm unit to sound an alarm, and passengers evacuate immediately. Subsequently, the controller activates the sprinkler fire extinguishing host 1 to spray extinguishing agent onto the fire point inside the cabin through the fixed sprinkler module, and simultaneously controls the activation of the movable sprinkler module to spray the fire point in a targeted manner, thereby effectively improving the speed of fire extinguishing, effectively preventing the fire from spreading further, and effectively reducing the probability of reignition.
[0061] During firefighting, the intelligent fire camera transmits the captured images to the video display module in real time via the controller. Back-end management personnel can monitor the situation inside the cabin in real time, providing a basis for subsequent emergency response measures. In addition, the data storage module can record the status of the sprinkler fire extinguishing host 1 and the monitoring data of the monitoring unit, and report them to the data processing module. The data processing module determines the fuel shortage status and whether there is a malfunction of the sprinkler fire extinguishing host 1 based on the provided data, and sends the corresponding instructions to the controller. The controller controls the sprinkler fire extinguishing host 1 and the drive mechanism to operate.
[0062] The controller activates the sprinkler fire suppression system 1 to spray extinguishing agent onto the fire point inside the cabin via the fixed sprinkler module, and simultaneously controls the activation of the movable sprinkler module to target the fire point. The specific process is as follows:
[0063] The controller controls the sprinkler fire extinguishing host 1 to start, and at the same time controls the first control valve 7 on the fire point location diversion pipe 4 to open. The extinguishing agent is transmitted through the sprinkler pipe 3 to the first diversion pipe 5 at the designated location, and is sprayed out through the first nozzle 6 on the first diversion pipe 5, thereby spraying and extinguishing the fire point.
[0064] Simultaneously, the controller starts the motor 11, which in turn drives the one-way screw 12 on the output shaft of the motor 11 to rotate, thereby driving the connecting block 13 to move forward along the guide rod, and thus driving the second nozzle 9, the box 14, and the second temperature sensor 22 to move synchronously; at the same time, the meshing of the first rack 19 and the first gear 18 drives the roller 15 to rotate, thereby driving the protective cover connected to one end of the rope 16 to move downward; at the same time, the meshing of the second gear 23 and the second rack 24 drives the bidirectional screw 26 to rotate, thereby driving the two sliders 20 to move closer to each other, and then the two connecting rods 21 drive the adapter block 2 to move downward along the inner wall of the cover 17, and the second temperature sensor 22 moves out of the cover 17, so that the second temperature sensor 22 can be closer to the ignition point, thus making it easier for the second temperature sensor 22 to identify the ignition point;
[0065] When the second temperature sensor 22 identifies the specific location of the ignition point, it transmits the signal to the controller. The controller controls the motor 11 to shut off, and the second nozzle 9 stops moving. At the same time, the controller controls the second control valve 10 to open. The extinguishing agent in the spray pipe 3 is sprayed to the ignition point through the second diversion pipe 8 and the second nozzle 9, thereby effectively improving the speed of extinguishing the fire and reducing the range of fire combustion.
[0066] When both the infrared flame detector and the second temperature sensor 22 determine that the fire has been completely extinguished, they transmit a signal to the controller. The controller then controls the motor 11 to rotate its output shaft in the opposite direction, which in turn drives the connecting block 13 to reset backward via the one-way screw 12. After the connecting block 13 resets backward and moves a certain distance, the first gear 18 re-engages with the first rack 19, which in turn drives the roller 15 to rotate in the opposite direction. This causes the protective cover connected to one end of the rope 16 to move upward. During the process of the protective cover resetting upward, the second gear 23 engages with the second rack 24, which drives the bidirectional screw 26 to rotate in the opposite direction, thereby causing the second temperature sensor 22 to automatically retract into the protective cover.
[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
