Description

Technical Field

[0001] This invention relates to the field of fire safety control, and in particular to automotive fire suppression devices. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, electric vehicles (EVs) have experienced rapid growth in the transportation sector due to their significant advantages such as zero emissions and low noise. In recent years, the market share of EVs has continued to climb, with more and more consumers choosing EVs as their daily mode of transportation. This trend has led to a surge in the number of EVs parked in parking lots, making them a common sight from underground parking garages of large commercial complexes to parking areas in residential communities. However, existing parking lots are mainly converted or directly constructed from traditional gasoline-powered vehicle parking lots. Their spatial layout and sprinkler fire control systems primarily consider the parking needs of gasoline-powered vehicles. During the planning and design, the special characteristics and dangers of trolley fires were not fully considered. Due to factors such as thermal runaway of batteries, trolley fires spread rapidly and have high combustion temperatures. Traditional sprinkler systems cannot effectively control the fire in the early stages, leading to further expansion of the fire. At the same time, there is a lack of areas specifically for isolating trolley fires. When trolleys and gasoline-powered vehicles are parked together, the fire can easily spread rapidly to surrounding vehicles, causing greater property damage and casualties. Summary of the Invention

[0003] To address the issues that existing parking lots cannot isolate trolley fires and that sprinkler systems cannot effectively control fires, this invention provides a vehicle fire suppression device.

[0004] The automotive fire suppression device provided by this invention adopts the following technical solution: A car fire suppression device includes a base frame and a fire control cabinet disposed on one side of the base frame. The fire control cabinet is provided with a fire control pipeline for conveying fire control solvent. A support frame is provided on the surface of the base frame. Movable slots are provided on opposite sides of both ends of the support frame. The linkage fire control mechanism includes a movable block that is movably installed in a movable slot. Multiple nozzles are installed at the bottom of the movable block. An extrusion plate is installed at the bottom of the support frame, aligned with the multiple nozzles. The multiple nozzles move and collide with the extrusion plate, causing them to shake. A rotating rod is rotatably installed inside the support frame on one side of the movable block. A heat insulation cloth is installed on the surface of the rotating rod. The movement of the movable block is linked to the rotation of the rotating rod. The rotation of the rotating rod lowers the heat insulation cloth to shield the tram.

[0005] By adopting the above technical solution, the fire control pipeline in the fire control cabinet delivers the fire control solvent to the nozzles, thereby spraying the burning trolley to control the fire. The moving block is limited by the moving groove and moves back and forth, thereby driving multiple nozzles to move synchronously to increase the spray coverage area. As the nozzles move, they are squeezed by the extrusion plate, causing the nozzles to swing. Combined with the movement of the nozzles themselves, a composite spraying action of swinging and reciprocating movement is formed, which effectively controls the fire. At the same time, the rotating rod rotates synchronously with the movement of the moving block, thereby lowering the heat insulation cloth to cover the side surface of the trolley, isolating the burning trolley from other vehicles and preventing the fire from spreading.

[0006] Preferably, the fire control pipeline includes a pump body installed inside the fire control cabinet, an inlet pipe is provided at the output end of the pump body, a switch valve is provided at the end of the inlet pipe away from the pump body, and a check valve is provided at the outlet end of the pump body to prevent backflow.

[0007] By adopting the above technical solution, the water inlet pipe is connected to the external medium supply equipment to deliver the medium to the pump body. The switch valve controls the channel between the medium supply equipment and the water inlet pipe. When the channel between the fluid and the water inlet pipe is open, the water inlet pipe provides the medium to the pump body, thereby allowing the medium to be delivered from the pump body to the check valve.

[0008] Preferably, the check valve is provided with a T-connector 1 at the end away from the pump body, a conduit is provided on one side of the surface of the T-connector 1, a T-connector 2 is provided at the end of the conduit away from the T-connector 1, a discharge pipe is provided at the end of the T-connector 2 away from the conduit, and a water outlet pipe is provided at the end of the discharge pipe away from the T-connector 2.

[0009] By adopting the above technical solution, the pump body delivers the medium to the inside of the check valve, the medium is delivered from the inside of the check valve to the inside of the first tee joint, the medium is delivered from the inside of the first tee joint to the inside of the conduit, the medium is delivered from the inside of the conduit to the inside of the second tee joint, the medium is delivered from the inside of the second tee joint to the inside of the outlet pipe, and the medium is delivered from the inside of the outlet pipe to the inside of the water outlet pipe, thereby completing the medium delivery work.

[0010] Preferably, a solenoid valve is provided on one side of the surface of the second tee connector, a return pipe is provided at the end of the solenoid valve away from the second tee connector, and a hydraulic sensor for monitoring pipeline pressure and fluid pressure is provided at the end of the first tee connector away from the conduit.

[0011] By adopting the above technical solution, when there is no fire, the pump body is started at regular intervals to draw out the medium. The pump body draws the medium into the check valve, and the medium enters the interior of the three-way connector one from the check valve. The medium enters the interior of the conduit from the interior of the three-way connector one, and the medium enters the interior of the three-way connector two from the interior of the three-way connector two. The medium enters the interior of the solenoid valve from the interior of the solenoid valve, and the medium enters the return pipe from the interior of the return pipe and returns to the fire control cabinet. In this way, by drawing the medium into the fire control cabinet, the pump body and pipeline are regularly monitored to ensure that the fire can be successfully controlled in the fire area.

[0012] Preferably, a reciprocating screw is rotatably arranged in the moving slot, the moving block is threadedly connected to the surface of the reciprocating screw, a connecting beam is fixed in the middle of the support frame, a linkage cavity is opened inside the connecting beam, the reciprocating screw is movably located in the linkage cavity, and a gear is fixed at the through end of the reciprocating screw.

[0013] By adopting the above technical solution, the reciprocating screw rotates, causing the moving block to move back and forth, thereby making the nozzle move synchronously and increasing the spraying range. At the same time, the opening of the linkage cavity provides space for the installation of gear one, and gear one receives power to drive the reciprocating screw to rotate.

[0014] Preferably, a toothed belt is meshed on the surface of the gear, a servo motor is fixedly mounted on the outer surface of the support frame at the middle position of the linkage cavity, the output end of the servo motor is movably inserted through the linkage cavity, and a drive gear is fixedly mounted on the output end of the servo motor, the drive gear being meshed with the toothed belt.

[0015] By adopting the above technical solution, the output end of the servo motor drives the drive gear to rotate, and the gear belt connects the drive gear and the gear, so that the drive gear drives the gear to rotate synchronously, thereby providing power for the rotation of the reciprocating screw.

[0016] Preferably, a rotating cavity is provided inside the support frame on one side of the moving groove. The rotating rod is rotatably disposed in the rotating cavity and moves through the linkage cavity. A gear two is fixedly provided therein. Gear belt two is meshed on both sides of the surface of gear two. A protruding tooth surface is provided on the surface of gear one at the positions of the two gear belt two. The protruding tooth surface is meshed with the gear belt two.

[0017] By adopting the above technical solution, the opening of the rotating cavity provides space for the installation of the rotating rod. The toothed belt connects the protruding tooth surface to the gear, so that the rotation of the gear drives the gear to rotate synchronously, providing power transmission for the rotation of the rotating rod.

[0018] Preferably, a spray pipe is fixed between the two movable blocks, the spray pipe is connected to the water outlet pipe, and multiple connecting hoses are fixed at the bottom of the spray pipe, each of the multiple connecting hoses being connected to a multiple nozzle.

[0019] By adopting the above technical solution, the moving block drives the nozzle to move, causing the connecting hose to be squeezed against the side surface of the extrusion plate. At the same time, the connecting hose and the spray pipe are fixedly connected, forming a thrust on the connecting hose and the nozzle. The nozzle is tilted to one side due to the thrust. When the extrusion plate pushes past the nozzle, the connecting hose, with its own elasticity and the impact force of the medium transmitted by the spray pipe, returns the nozzle to its original position. During the tilting process of the nozzle, the whole body swings, thereby making the spray angle more comprehensive.

[0020] Preferably, a fire-resistant base is fixed in the middle of the base frame, and drainage grooves are provided on both sides of the fire-resistant base. A bottom heat array is fixed in the fire-resistant base, and a top heat array is fixed in the side of the connecting beam near the bottom heat array.

[0021] By adopting the above technical solution, the bottom thermal array and the top thermal array collect temperature and humidity information around the tram to transmit the fire status, and the fire-resistant base is in direct contact with the tram to isolate the tram from the ground.

[0022] Preferably, the fire control cabinet is equipped with a circuit board for analyzing the internal fire situation based on information collected by the bottom and top thermal arrays, and a controller for temporary manual operation is fixed on one side of the outer surface of the support frame.

[0023] By adopting the above technical solution, the bottom thermal array and the top thermal array collect feedback on the fire status, which is then comprehensively analyzed by the circuit board, and the opening and closing of the solenoid valve and the start of the servo motor are controlled to achieve the dynamic detection function of automatic fire control. At the same time, personnel can control the servo motor and the pump body through the controller to more comprehensively control the fire situation.

[0024] In summary, the present invention has at least one of the following beneficial technical effects: 1. Real-time detection of trolley fires is achieved using bottom and top thermal arrays, and the fire control pipeline delivers fire control solvent to the nozzles for spraying the trolley. Simultaneously, the spray pipeline moves back and forth on the top of the trolley, causing the connecting hose to collide with the extrusion plate. This interaction force causes the connecting hose to deflect. As the spray pipeline continues to move, the connecting hose swings, resulting in a combined spraying action of moving and swinging the nozzles. This increases the fire control range and angle, effectively controlling trolley fires. 2. By using gear one to drive gear two to rotate synchronously, the reciprocating screw and the rotating rod rotate synchronously. While the nozzles are spraying, the rotating rod loosens the heat insulation cloth, which is then lowered to cover both sides of the burning tram, effectively preventing the fire from spreading to other parked vehicles.

[0027] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0028] This invention discloses an automotive fire suppression device.

[0029] Reference Figure 1 , Figure 2 , Figure 3The fire suppression device for automobiles includes a base frame 2 and a fire control cabinet 1 disposed on one side of the base frame 2. A cabinet door 11 is hinged to one side of the surface of the fire control cabinet 1. The side of the cabinet door 11 near the surface of the base frame 2 is closed by a lock body and a latch. The fire control cabinet 1 is provided with a fire control pipeline 7 for conveying fire control solvent. The fire control pipeline 7 includes a pump body 71 fixedly connected inside the fire control cabinet 1. A water inlet pipe 72 is fixedly connected to the input end of the pump body 71. The end of the water inlet pipe 72 away from the pump body 71 is fixedly connected to the output end of a medium supply device, so that the medium supply device provides medium to the water inlet pipe 72. A switch valve 73 for blocking the medium inside the water inlet pipe 72 is connected to the surface of the water inlet pipe 72 by a one-inch internal thread elbow. A check valve 74 is fixedly connected to the outlet end of the pump body 71 to prevent liquid backflow. The arrow of the check valve 74 points upward. The end of the check valve 74 away from the pump body 71 is connected to a tee connector 75 via an internal thread. A conduit 76 is installed inside the fire control cabinet 1. The end of the conduit 76 near the check valve 74 is connected to the end of the tee connector 75 away from the check valve 74 via a one-inch male thread connector. The end of the conduit 76 away from the tee connector 75 is connected to a... Three-way connector 2 77, the end of three-way connector 2 77 away from conduit 76 is connected to outlet pipe 78 through external thread connector, outlet pipe 78 penetrates the surface of fire control cabinet 1 near charging base frame 2, outlet pipe 79 is fixedly connected to outlet pipe 78 at the end of outlet pipe 78 away from three-way connector 2 77, solenoid valve 771 is connected to solenoid valve 771 through external thread connector, solenoid valve 771 is fixedly connected to return pipe 772 at the end of solenoid valve 771 away from three-way connector 2 77; It should be noted that the end of the tee connector 75 furthest from the conduit 76 is connected to a hydraulic sensor 8 via an internal threaded connector for monitoring pipeline pressure and fluid pressure. The hydraulic sensor 8 can monitor the internal pressure of the pipeline and fluid pressure in real time to determine whether the pipeline is damaged and whether the fire control spray has reached the predetermined value.

[0030] Reference Figure 4 , Figure 5 , Figure 6 A fire-resistant base 21 is fixedly installed in the middle of the upper surface of the base frame 2. The fire-resistant base 21 is made of composite carbide 4C-ZrC material and is covered with a protective coating. A drainage groove 23 is provided between the base frame 2 and the fire-resistant base 21. The drainage groove 23 is connected to the external drainage system so as to drain the medium on the ground when the device sprays fire control. Support frames 3 are fixedly installed on both sides of the upper surface of the base frame 2 located on the fire-resistant base 21. A connecting beam 32 is fixedly installed between the two support frames 3 to form an integral fixation. A moving groove 31 is provided on the opposite side surface of the two support frames 3. The linkage fire control mechanism 5 includes a movable block 51 that is movably disposed in a movable groove 31. A reciprocating screw 55 is rotatably disposed in the movable groove 31. The screw surface is machined with two sets of intersecting spiral grooves on the left and right. The movable block 51 is threadedly connected to the reciprocating screw 55, and the shape of the movable block 51 is fitted into the groove of the movable groove 31, so that when the reciprocating screw 55 rotates, the movable block 51 moves back and forth in a straight line along the surface of the reciprocating screw 55. A spray pipe 52 is fixed between the two movable blocks 51, and multiple connecting hoses 53 are connected to the bottom of the spray pipe 52 facing the tram parking position. A nozzle 54 is fixed at the bottom of each of the multiple connecting hoses 53. The nozzle 54 uses a spray nozzle and has a conical bottom, so that the water mist sprayed by the nozzle 54 is umbrella-shaped, thereby increasing the fire control range. It should be noted that a compression plate 12 is fixed between the two support frames 3 on opposite sides. The surface of the compression plate 12 is provided with multiple rectangular openings, and each rectangular opening is wrapped around the connecting hose 53. This causes the connecting hose 53 to be squeezed by the compression plate 12 when it moves. Since the compression plate 12 and the support frame 3 are fixed, an interaction force is generated, which pushes the connecting hose 53 to tilt and deflect in the opposite direction. When the connecting hose 53 is completely separated from the compression plate 12, the elasticity of the connecting hose 53, combined with the impact of the continuously transported fluid, rebounds in the opposite direction, thereby generating an overall swinging motion and increasing the spray coverage angle.

[0031] Reference Figure 5 , Figure 6 , Figure 7 The support frame 3 has a rotating cavity 33 on each of the two moving slots 31 on opposite sides. A rotating rod 511 is rotatably installed in the rotating cavity 33. A heat insulation cloth 6 is rolled up on the surface of the rotating rod 511. The support frame 3 has a through slot at the bottom of the heat insulation cloth 6 that passes through the rotating cavity 33. The bottom of the heat insulation cloth 6 extends to the outside through the through slot of the rotating cavity 33. A counterweight is fixed at the extended end of the heat insulation cloth 6. The counterweight is made of 316 stainless steel strip and its weight is greater than the lifting force of the rising hot air flow on the cloth surface in the fire, so as to ensure that the heat insulation cloth can still be deployed vertically and fit the ground drainage ditch 23 in the fire cyclone. When the rotating rod 511 rotates to loosen the heat insulation cloth 6, the counterweight drives the heat insulation cloth 6 to descend, thereby isolating the tram from the outside. A linkage cavity 34 is provided inside the connecting beam 32. One end of the rotating rod 511 movably passes through the side surface, and a second gear 510 is fixedly installed inside the linkage cavity 34. At the same time, one end of the reciprocating screw 55 also movably passes through the linkage cavity 34, and a first gear 56 is fixedly installed on its through surface. Both sides of the surface of the first gear 56 have protruding tooth surfaces 57. A second toothed belt 59 is meshed on the two protruding tooth surfaces 57. The ends of the two second toothed belts 59 away from the protruding tooth surfaces 57 are meshed with the surface of the second gear 510, forming a synchronous rotation state between the first gear 56 and the second gear 510. The diameter of the protruding tooth surfaces 57 is larger than that of the second gear 510, and both sides of the second toothed belt 59 abut against the inner wall of the linkage cavity 34 to prevent the connection between the second toothed belt 59 and the first gear 56 and the second gear 510 from loosening. A servo motor 512 is fixedly mounted in the middle of the side surface of the connecting beam 32. The servo motor 512 is a 380V AC servo motor with overload protection. A high-temperature protective cover can also be installed on the surface of the servo motor 512. The output end of the servo motor 512 movably passes through the connecting beam 32 and extends into the linkage cavity 34. A drive gear 513 is fixedly mounted on the extended end of the servo motor 512. A toothed belt 58 is meshed with the surface of the drive gear 513. The two ends of the toothed belt 58 away from the drive gear 513 are respectively meshed with the surfaces of two gears 56. The toothed belt 58 is located between two toothed belts 59 and is subjected to an overall clamping effect, forming a relative lateral stability between the toothed belt 58 and the toothed belt 59 (e.g., Figure 5 As shown, the diameter ratio of the drive gear 513 to the gear 56 is 1:1, ensuring that the reciprocating screw 55 obtains a stable torque.

[0032] It should be noted that a bottom heat array 22 is fixed in the middle of the surface of the fire-resistant base 21, and a top heat array 10 is fixed on the side surface of the connecting beam 32 near the bottom heat array 22. A circuit board 4 is fixedly connected inside the fire control cabinet 1. The circuit board 4 analyzes the fire status inside the base frame 2 based on the information collected by the bottom heat array 22 and the top heat array 10. The bottom heat array 22, the top heat array 10, the servo motor 512 and the solenoid valve 771 are connected to the circuit board 4 by a direct level control method. The direct level control method is existing technology, and the specific principle will not be described in detail. At the same time, a controller 9 is fixed on one side of the outer surface of the support frame 3. Personnel can manually control the servo motor 512 and the solenoid valve 771 through the controller 9.

[0033] The implementation principle of the vehicle fire suppression device in this embodiment of the invention is as follows: the circuit board 4 controls the pump body 71 to draw fire control solvent (water, aerogel fire control agent, Hq-ev3 series fire control temperature control liquid) from the medium supply equipment, and delivers the medium to the spray area inside the support frame 3 through the fire control pipeline 7. The solenoid valve 771 corresponding to the fire area is opened at a fixed point, so that the nozzle 54 in the fire area sprays the medium to control the fire at a fixed point. When the situation of "the local fire has been manually extinguished, but the nozzle 54 is still spraying continuously" occurs inside the support frame 3, the staff does not need to wait for the control circuit board 4 to automatically identify the fire situation and can directly press the button of the controller 9 to stop the spraying, so as to avoid the continuous waste of fire control solvent. When no fire occurs, the pump body 71 draws the medium into the medium supply equipment to periodically monitor whether the pump body 71 and the pipeline are in normal operating condition, so as to ensure that the fire area can be successfully controlled in the future. Simultaneously, while the nozzles 54 are spraying, the circuit board 4 controls the servo motor 512 to operate. The servo motor 512 drives the drive gear 513 to rotate, causing the gear 56 meshing with the toothed belt 58 to rotate synchronously. The gear 56 drives the reciprocating screw 55 to rotate synchronously, causing the moving block 51 to move back and forth along the surface of the reciprocating screw 55, thereby driving multiple nozzles 54 to move back and forth, increasing the spray coverage of the nozzles 54. As the moving block 51 moves, the connecting hose 53 is squeezed against the extrusion plate 12, generating an interaction force that causes the connecting hose 53 to deflect. After the extrusion plate 12 separates from the connecting hose 53, the connecting hose 53 rebounds in the opposite direction due to its own elasticity and the impact force from the transmission medium, causing the nozzles 54 to swing as a whole, increasing the spray angle. As gear 56 rotates, gear 510, which meshes with belt 59, rotates synchronously. Gear 510 rotates to loosen the rolled-up heat insulation cloth 6. Then, the heat insulation cloth 6 is pressed down by the counterweight and unfolds downward, thus covering the side surface of the tram, isolating the burning tram from the other vehicles and effectively preventing the fire from spreading to the surrounding areas.

[0034] The above are merely optional embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
