Description

Technical Field

[0001] This invention relates to the field of fire fighting technology, specifically to a fixed ship deck real fire simulation training device and method. Background Technology

[0002] Modern ships possess a wide variety and numerous fire hazards, and fire accidents pose a significant threat to ship safety. Fire simulation training devices are of practical significance for improving crew members' firefighting skills and enhancing the ship's firefighting capabilities. Traditional ship deck firefighting training utilizes liquid fuel live fire (oil fire) drills, conducting real fire exercises at one or more locations on the ship's deck. Among these, gas-fired live fire simulation training has become a crucial method. Gas-fired training devices primarily rely on the control module of the combustion unit to adjust valve openings and thus control the flame to achieve fire simulation training. Currently, in actual ship deck firefighting drills, the most common firefighting method involves crew members manually spraying water or foam onto the deck through surrounding fire hoses. This requires constant manual shaking and swaying of the hoses, is time-consuming and labor-intensive, lacks precision, and makes it difficult to continuously extinguish multiple fire points, easily leading to fluctuating fire intensities.

[0003] In contrast, an existing patent (publication number: CN115779302A) discloses a fire-fighting system for a ship's helicopter deck. This invention includes a base with a fixed platform; a fire-fighting mechanism mounted on the base, comprising a water storage component on the base and a pumping component on one side of the water storage component. The water storage component includes a water tank mounted on the fixed platform and a tank cover on the water tank. The pumping component includes a pump mounted on the fixed platform and an installation pipe on one side of the pump. This invention provides a fire-fighting system for a ship's helicopter deck. The system is controlled by a control mechanism. Foaming agent is added to the water tank, and a stirring component ensures the foaming agent functions effectively. The foam pumped by the foam pump is then sprayed through foam nozzles to extinguish fires on the ship's deck. This significantly increases the fire-fighting efficiency of the system while reducing the labor intensity of manual firefighting and ensuring the safety of firefighters.

[0004] However, while the above-mentioned scheme achieves targeted fire suppression, it is difficult to carry out comprehensive firefighting work in the event of a large-scale fire. Summary of the Invention

[0005] This invention proposes a fixed ship deck real fire simulation training device and method, which solves the problem in related technologies that the accuracy is insufficient when extinguishing fires, making it difficult to continuously extinguish multiple fire points one by one, and easily causing the fire intensity to fluctuate.

[0006] The technical solution of the present invention is as follows: A fixed ship deck real fire fire simulation training device includes: a ship deck body, a U-shaped frame fixedly installed on the top of one side of the ship deck body, and two support frames fixedly connected to the top of the other side of the ship deck body. A guide assembly is fixedly connected to the top of the two support frames. Multiple spray rods are arranged between the guide assembly and the U-shaped frame. Multiple transmission assemblies, which are the same number as the number of spray rods and correspond one-to-one, are arranged between the U-shaped frame and the guide assembly. The transmission assembly includes a first lead screw and a second lead screw spliced ​​together. A driving mechanism is provided on the guide assembly for rotating the first lead screw and the second lead screw, thereby driving the spray rods to move.

[0007] A flame-retardant output mechanism is provided on the guide assembly. The flame-retardant output mechanism includes an outer frame fixedly connected to the outer wall of the guide assembly. A rotating main pipe is rotatably arranged inside the outer frame. The rotating main pipe extends to the outer side of the outer frame and is connected to a feed pipe. The end of the feed pipe is rotatably connected to the rotating main pipe. Multiple branch pipes, which are the same number as the number of spray rods and correspond one-to-one, are fixedly connected to the outer wall of the rotating main pipe. The branch pipes slide through the top of the outer frame and are connected to the inside of the spray rods.

[0008] Preferably, the transmission assembly further includes a first star-shaped seat fixedly connected to the end of the first lead screw away from the second lead screw, a plurality of first limiting rods are arranged in a ring on the outer wall of the end of the second lead screw away from the first lead screw, a second star-shaped seat is fixed at the end of the first lead screw near the second lead screw, and a first star-shaped cavity is opened at the end of the second lead screw near the first lead screw for the second star-shaped seat to be inserted.

[0009] Preferably, a sliding column is slidably sleeved inside the U-shaped frame, a sliding cavity is opened inside the U-shaped frame for the sliding column to slide, an overlapping cylinder is rotatably sleeved inside the sliding column, a limiting cavity is opened on the inner side of the overlapping cylinder for the insertion of the second lead screw and the first limiting rod, and a connecting spring is fixedly connected between the sliding column and the sliding cavity.

[0010] Preferably, a receiving cavity is provided inside the spray bar, and multiple nozzles communicating with the receiving cavity are fixed at the bottom of the spray bar. Multiple hollow shafts, which are the same number as the number of transmission components and correspond one-to-one, are fixed through the inside of one side of the spray bar. The inner diameter of the hollow shaft is larger than the outer diameter of the first lead screw. Each spray bar is provided with an internally threaded tube that is threaded with the first lead screw and the second lead screw. The internally threaded tube is fixedly sleeved inside the hollow shaft, and the internally threaded tubes on the multiple spray bars are distributed sequentially from right to left.

[0011] Preferably, the guide assembly includes a slide frame fixedly connected to the top of two support frames, with two slide grooves inside one side of the slide frame, and multiple sets of insertion holes on the inner wall of the slide frame above the slide grooves, and the first lead screw extends to the inner side of the slide frame and is rotatably connected thereto.

[0012] Preferably, the driving mechanism includes a motor clamped inside the slide frame, two slide rods fixed at the bottom of the motor, the slide rods slidingly engaging with the slide groove, and a set of limiting components provided at the top of the motor;

[0013] The limiting component includes a plug rod that slides to the top of the motor and mates with the socket, and a support spring that supports the plug rod is fixedly connected between the plug rod and the inside of the top of the motor.

[0014] Preferably, a star-shaped shaft is fixed to the end of the motor shaft, a linkage cylinder is provided on the outside of the star-shaped shaft, a star-shaped groove is provided inside the linkage cylinder for the star-shaped shaft to be inserted, a return spring is fixedly connected between the star-shaped shaft and the star-shaped groove, and a triangular overlapping cavity is provided at the end of the linkage cylinder away from the motor shaft for the first star-shaped seat to be inserted.

[0015] Preferably, a plurality of fixing discs, which are the same as the number of branch pipes, are fixed between the upper and lower inner walls of the outer frame. The plurality of fixing discs divide the rotating main pipe into multiple segments, and the number of segments is the same as the number of branch pipes and corresponds one-to-one. The segments are used to wind and coil the branch pipes. Adjacent segments of the rotating main pipe are rotatably connected and communicate with each other.

[0016] The left end of each rotating manifold passes through a fixed disk located on its right side and is rotatably connected to the fixed disk. A coil spring is connected between the rotating manifold and the fixed disk.

[0017] Preferably, a guide rod is connected between the U-shaped frame and the guide assembly. The guide rod includes a first guide rod and a second guide rod that are spliced ​​together. The first guide rod extends slidably into the interior of multiple spray rods and is fixedly connected to the slide frame. A third star-shaped seat is fixed at the end of the first guide rod near the second guide rod. A second star-shaped cavity for the third star-shaped seat to be inserted is opened at the end of the second guide rod near the first guide rod. A second limiting rod is fixed on the outer wall of the end of the second guide rod away from the first guide rod.

[0018] A method for simulated firefighting on a fixed ship deck, using any of the fixed ship deck firefighting simulation training devices as claimed above, includes the following steps:

[0019] S1: Set up multiple ignition points on the main body of the ship's deck, and connect the feed pipe to the corresponding fire extinguisher pipeline according to the fire source information;

[0020] S2: Adjust the position of the spray bar according to the location of the ignition point. During the adjustment, turn on the power and start the motor. The motor drives the star shaft to rotate through the machine shaft. The star shaft drives the linkage cylinder to rotate. The linkage cylinder drives the first lead screw and the second lead screw connected to each other on a certain transmission component to rotate. When the first lead screw and the second lead screw rotate, they can drive the spray bar that is threaded with them to move.

[0021] S3: When multiple spray bar positions need to be adjusted, the linkage cylinder can be pressed towards the star shaft side, causing the return spring to compress and the star shaft to slide into the star groove. This allows the triangular overlapping cavity to slide out from the first star seat at the end of one of the first lead screws. Then, the motor is manually pushed to move the motor inside the slide frame. During this process, the insert rod is squeezed and compressed back into the top of the motor to ensure that the motor can move normally until it reaches the designated position. Under the action of the support spring, the insert rod moves up and resets and is inserted into the insertion hole, limiting the motor. At this time, the pressure on the linkage cylinder is released, and under the action of the return spring, the linkage cylinder resets and is fitted onto the first star seat at the end of another first lead screw. At this time, the motor can rotate the first lead screw, thereby realizing the adjustment of the position of different spray bars.

[0022] S4: As the spray bar moves away from the outer frame, it pulls the branch pipe, which drives the rotating main pipe to rotate and gradually tightens the coil spring. When the spray bar moves closer to the outer frame, the coil spring gradually relaxes, rotates the rotating main pipe to reset, and rewinds the branch pipe.

[0023] S5: During fire extinguishing drills, the feed pipe is connected to the external fire extinguishing device pipeline. The external fire extinguishing device delivers the extinguishing agent through the feed pipe to the rotating main pipe, which then delivers the extinguishing agent to multiple branch pipes. The branch pipes deliver the extinguishing agent to the spray bar, and the nozzles spray the extinguishing agent downwards for targeted fire extinguishing.

[0024] The working principle and beneficial effects of this invention are as follows:

[0025] In this invention, a guide assembly is fixedly connected to the top of two support frames. Multiple spray rods are arranged between the guide assembly and the U-shaped frame. Multiple transmission assemblies, corresponding one-to-one with the number of spray rods, are arranged between the U-shaped frame and the guide assembly. Each transmission assembly includes a first lead screw and a second lead screw connected to each other. A drive mechanism and a flame-retardant output mechanism are provided on the guide assembly. A motor on the drive mechanism can rotate the first and second lead screws, thereby moving the spray rods. Furthermore, the motor can translate on the guide assembly, driving different transmission assemblies individually, thus allowing for position adjustments of different spray rods. As the spray rods move away from the outer frame of the flame-retardant output mechanism, they pull on the branch pipes, causing the rotating main pipe to rotate and gradually tighten the coil springs. When the spray rods approach the outer frame, the coil springs gradually relax, rotating and resetting the rotating main pipe, and rewinding the branch pipes. During fire extinguishing drills, the feed pipe is connected to the external fire extinguishing device pipeline. The external fire extinguishing device delivers the extinguishing agent through the feed pipe to the rotating main pipe, which then delivers the extinguishing agent to multiple branch pipes. The branch pipes then deliver the extinguishing agent to the spray bar, and the extinguishing agent is sprayed downwards through the nozzles. This method can achieve local or comprehensive fire extinguishing. It is simple to operate, convenient to use, saves time and effort, and has high practical value.

[0026] In this invention, after the firefighting work is completed, multiple spray rods can be sequentially attached and stored, and the second lead rod and the second guide rod can be disassembled, so that there is sufficient space for movement above the main body of the ship's deck.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 as well as Figure 13 A fixed ship deck fire simulation training device includes: a ship deck body 1, a U-shaped frame 2 fixedly installed on the top of one side of the ship deck body 1, and two support frames 3 fixedly connected to the top of the other side of the ship deck body 1. A guide assembly 4 is fixedly connected to the top of the two support frames 3. Multiple spray rods 7 are arranged between the guide assembly 4 and the U-shaped frame 2. Multiple transmission assemblies 9, which are the same number as the spray rods 7 and correspond one-to-one, are arranged between the U-shaped frame 2 and the guide assembly 4. The transmission assembly 9 includes a first lead screw 91 and a second lead screw 92 spliced ​​together. The transmission assembly 9 also includes a first star-shaped seat 93 fixedly connected to the end of the first lead screw 91 away from the second lead screw 92. A plurality of first limiting rods 94 are arranged in a ring on the outer wall of the end of the second lead screw 92 away from the first lead screw 91. A second star-shaped seat 96 is fixedly fixed to the end of the first lead screw 91 near the second lead screw 92. A first star-shaped cavity 95 is opened at the end of the second lead screw 92 near the first lead screw 91 for the second star-shaped seat 96 to be inserted. A sliding column 99 is slidably sleeved inside the U-shaped frame 2. A sliding cavity is opened inside the U-shaped frame 2 for the sliding column 99 to slide. An overlapping cylinder 97 is rotatably sleeved inside the sliding column 99. A limiting cavity 971 is opened on the inner side of the overlapping cylinder 97 for the second lead screw 92 and the first limiting rod 94 to be inserted. A connecting spring 98 is fixedly connected between the sliding column 99 and the sliding cavity.

[0045] A receiving cavity 74 is provided inside the spray rod 7. Multiple nozzles 73 connected to the receiving cavity 74 are fixed at the bottom of the spray rod 7. Multiple hollow shafts 71, which are the same number as the transmission components 9 and correspond one-to-one, are fixed through one side of the spray rod 7. The inner diameter of the hollow shaft 71 is larger than the outer diameter of the first lead screw 91, that is, the first lead screw 91 does not contact the inner wall of the hollow shaft 71. Each spray rod 7 is provided with an internally threaded tube 72 that is threaded with the first lead screw 91 and the second lead screw 92. The internally threaded tube 72 is fixedly sleeved inside the hollow shaft 71. The internally threaded tubes 72 on the multiple spray rods 7 are distributed from right to left.

[0046] During the drill, multiple ignition points were set up on the main deck 1 of the ship, and the feed pipe 53 was connected to the corresponding fire extinguisher pipeline, such as a foam extinguishing pipeline or a water pipeline, according to the fire source information. The position of the spray bar 7 was adjusted according to the location of the ignition point. During the adjustment, the first lead screw 91 and the second lead screw 92, which are spliced ​​together on a certain transmission component 9, were rotated. When the first lead screw 91 and the second lead screw 92 rotated, the spray bar 7, which was threaded to them, could be moved.

[0047] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 A drive mechanism 6 is provided on the guide assembly 4 to rotate the first lead screw 91 and the second lead screw 92, thereby driving the spray bar 7 to move. The guide assembly 4 includes a sliding frame 41 fixedly connected to the top of the two support frames 3. Two sliding grooves 42 are opened inside one side of the sliding frame 41. Multiple sets of insertion holes 43 are opened on the inner wall of the sliding frame 41 above the sliding grooves 42. The first lead screw 91 extends to the inner side of the sliding frame 41 and is rotatably connected to it.

[0048] The drive mechanism 6 includes a motor 61 clamped inside the slide frame 41. Two slide rods 63 are fixed at the bottom of the motor 61, and the slide rods 63 slide against the slide groove 42. A set of limiting components 62 is provided at the top of the motor 61. The limiting components 62 include a plug rod 621 that slides to the top of the motor 61 and cooperates with the insertion hole 43. A support spring 622 is fixedly connected between the plug rod 621 and the inside of the top of the motor 61 to support the plug rod 621. A star-shaped shaft 65 is fixed to the end of the motor shaft 64. A linkage cylinder 66 is provided outside the star-shaped shaft 65. A star-shaped groove 68 is opened inside the linkage cylinder 66 for the star-shaped shaft 65 to be inserted. A return spring 69 is fixedly connected between the star-shaped shaft 65 and the star-shaped groove 68. A triangular overlapping cavity 67 is opened at the end of the linkage cylinder 66 away from the motor shaft 64 for the first star seat 93 to be inserted.

[0049] When the power is turned on, the motor 61 is started. The motor 61 drives the star shaft 65 to rotate through the machine shaft 64. The star shaft 65 drives the linkage cylinder 66 to rotate. The linkage cylinder 66 drives the first lead screw 91 and the second lead screw 92 spliced ​​together on a certain transmission component 9 to rotate. When it is necessary to adjust the position of multiple spray bars 7, the linkage cylinder 66 can be pressed towards the star-shaped shaft 65, causing the return spring 69 to compress and the star-shaped shaft 65 to slide into the star-shaped groove 68. This allows the triangular overlapping cavity 67 to slide out from the first star-shaped seat 93 at the end of one of the first lead screws 91. Then, the motor 61 is manually pushed, causing the motor 61 to translate inside the slide frame 41. During this process, the insertion rod 621 is squeezed and compressed back into the top of the motor 61, ensuring that the motor 61 can translate normally until it reaches the designated position. Under the action of the support spring 622, the insertion rod 621 moves upward and resets, and is inserted into the insertion hole 43, limiting the motor 61. At this time, the pressure on the linkage cylinder 66 is released, and under the action of the return spring 69, the linkage cylinder 66 resets and is sleeved on the first star-shaped seat 93 at the end of another first lead screw 91. At this time, the motor 61 can rotate the first lead screw 91, thereby realizing the adjustment of the position of different spray bars 7.

[0050] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 13 A flame-retardant output mechanism 5 is provided on the guide assembly 4. The flame-retardant output mechanism 5 includes an outer frame 51 fixedly connected to the outer wall of the guide assembly 4. A rotating main tube 52 is rotatably arranged inside the outer frame 51. The rotating main tube 52 extends to the outside of the outer frame 51 and is connected to a feed tube 53. The end of the feed tube 53 is rotatably connected to the rotating main tube 52. Multiple branch tubes 54, which are the same number as the number of spray rods 7, are fixedly connected to the outer wall of the rotating main tube 52. The branch tubes 54 slide through the top of the outer frame 51 and are connected to the inside of the spray rods 7. Multiple fixing discs 56, which are the same number as the number of branch tubes 54, are fixed between the upper and lower inner walls of the outer frame 51. The multiple fixing discs 56 divide the rotating main tube 52 into multiple segments, and the number of segments is the same as the number of branch tubes 54 and corresponds to the number of branch tubes 54. These segments are used to wind and coil the branch tubes 54. Adjacent segments of the rotating main tube 52 are rotatably connected and communicate with each other. Each rotating manifold 52 has a fixed plate 56 located on its right side at its left end, and is rotatably connected to the fixed plate 56. A coil spring 55 is connected between the rotating manifold 52 and the fixed plate 56.

[0051] As the spray boom 7 moves away from the outer frame 51, it pulls on the branch pipes 54, causing the rotating main pipe 52 to rotate and gradually tightening the coil spring 55. When the spray boom 7 approaches the outer frame 51, the coil spring 55 gradually relaxes, rotating the rotating main pipe 52 back to its original position and rewinding the branch pipes 54. During fire drills, the feed pipe 53 is connected to an external fire extinguishing system. The external fire extinguishing system delivers extinguishing agent through the feed pipe 53 to the rotating main pipe 52, which then delivers the extinguishing agent to multiple branch pipes 54. From there, the extinguishing agent is delivered to the spray boom 7 and sprayed downwards through the nozzles 73 for targeted fire suppression. It should be noted that valves can be installed on the nozzles 73 to control their opening and closing.

[0052] Please see Figure 1 , Figure 10 , Figure 11 as well as Figure 14 A guide rod 8 connects the U-shaped frame 2 and the guide assembly 4. The guide rod 8 includes a first guide rod 81 and a second guide rod 82 that are spliced ​​together. The first guide rod 81 slides into the interior of the multiple spray rods 7 and is fixedly connected to the sliding frame 41. A third star-shaped seat 83 is fixed to the end of the first guide rod 81 near the second guide rod 82. A second star-shaped cavity 84 is opened at the end of the second guide rod 82 near the first guide rod 81 for the third star-shaped seat 83 to be inserted. A second limiting rod 85 is fixed to the outer wall of the end of the second guide rod 82 away from the first guide rod 81. It is worth noting that the same structure as the overlapping cylinder 97, limiting cavity 971, sliding column 99, and connecting spring 98 is also provided between the guide rod 8 and the U-shaped frame 2 for limiting the installation of the second guide rod 82. The guide rod 8 provides good support and guidance for the movement of the spray rods 7.

[0053] Working principle and usage process: During operation, multiple ignition points are set on the main deck 1 of the ship, and the feed pipe 53 is connected to the corresponding fire extinguisher pipeline, such as foam extinguishing pipeline or water pipeline, according to the fire source information. The position of the spray bar 7 is adjusted according to the location of the ignition point. During adjustment, the power is turned on and the motor 61 is started. The motor 61 drives the star shaft 65 to rotate through the shaft 64. The star shaft 65 drives the linkage cylinder 66 to rotate. The linkage cylinder 66 drives the first lead screw 91 and the second lead screw 92 connected to each other on a certain transmission component 9 to rotate. When the first lead screw 91 and the second lead screw 92 rotate, they can drive the spray bar 7, which is threaded with them, to move. When it is necessary to adjust the position of multiple spray bars 7, the linkage cylinder 66 can be pressed towards the star-shaped shaft 65, causing the return spring 69 to compress and the star-shaped shaft 65 to slide into the star-shaped groove 68. This allows the triangular overlapping cavity 67 to slide out from the first star-shaped seat 93 at the end of one of the first lead screws 91. Then, the motor 61 is manually pushed, causing the motor 61 to translate inside the slide frame 41. During this process, the insertion rod 621 is squeezed and compressed back into the top of the motor 61, ensuring that the motor 61 can translate normally until it reaches the designated position. Under the action of the support spring 622, the insertion rod 621 moves upward and resets, and is inserted into the insertion hole 43, limiting the motor 61. At this time, the pressure on the linkage cylinder 66 is released, and under the action of the return spring 69, the linkage cylinder 66 resets and is sleeved on the first star-shaped seat 93 at the end of another first lead screw 91. At this time, the motor 61 can rotate the first lead screw 91, thereby realizing the adjustment of the position of different spray bars 7. As the spray boom 7 moves away from the outer frame 51, it pulls on the branch pipes 54, causing the rotating main pipe 52 to rotate and gradually tightening the coil spring 55. When the spray boom 7 approaches the outer frame 51, the coil spring 55 gradually relaxes, rotating the rotating main pipe 52 back to its original position and rewinding the branch pipes 54. During fire extinguishing drills, the feed pipe 53 is connected to the external fire extinguishing device pipeline. The external fire extinguishing device delivers the extinguishing agent through the feed pipe 53 to the rotating main pipe 52, which then delivers the extinguishing agent to multiple branch pipes 54. The branch pipes 54 deliver the extinguishing agent to the spray boom 7, and the nozzle 73 sprays the extinguishing agent downwards for targeted fire extinguishing.

[0054] After the drill, the sliding column 99 is pressed towards the inside of the U-shaped frame 2 by the overlapping sleeve 97, which compresses the connecting spring 98 and causes the overlapping sleeve 97 to disengage from the end of the second lead screw 92 (see details). Figure 9 , Figure 10 as well as Figure 11At this point, the first star-shaped cavity 95 at the end of the second lead screw 92 can be detached from the second star-shaped seat 96, completing the disassembly of the second lead screw 92. Similarly, the second guide rod 82 can be detached from the first guide rod 81, providing sufficient space for movement above the main body of the ship's deck 1.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.

4. A method for simulated firefighting on a fixed ship deck, using any one of the simulated firefighting devices for a fixed ship deck as described in claims 1-3, characterized in that, Includes the following steps: S1: Set multiple ignition points on the main body of the ship deck (1), and connect the feed pipe (53) to the corresponding fire extinguisher pipe according to the fire source information; S2: Adjust the position of the spray bar (7) according to the location of the ignition point. When adjusting, turn on the power and start the motor (61). The motor (61) drives the star shaft (65) to rotate through the machine shaft (64). The star shaft (65) drives the linkage cylinder (66) to rotate. The linkage cylinder (66) drives the first lead screw (91) and the second lead screw (92) spliced ​​on a certain transmission component (9) to rotate. When the first lead screw (91) and the second lead screw (92) rotate, they can drive the spray bar (7) that is threaded with them to move. S3: When it is necessary to adjust the position of multiple spray bars (7), the linkage cylinder (66) can be pressed towards the star shaft (65) to compress the return spring (69), and the star shaft (65) slides into the star groove (68), so that the triangular overlapping cavity (67) can slide out from the first star seat (93) at the end of one of the first lead screws (91). Then, the motor (61) is manually pushed to make the motor (61) translate inside the slide frame (41). During this process, the insert rod (621) is squeezed and compressed back into the top of the motor (61). Ensure that the motor (61) can move normally until it moves to the designated position. Under the action of the support spring (622), the insertion rod (621) moves up and resets and is inserted into the insertion hole (43) to limit the motor (61). At this time, release the pressure on the linkage cylinder (66). Under the action of the reset spring (69), the linkage cylinder (66) resets and is sleeved on the first star seat (93) at the end of another first lead screw (91). At this time, the motor (61) can rotate the first lead screw (91) to realize the adjustment of the position of different spray bars (7). S4: As the spray bar (7) moves away from the outer frame (51), it pulls the branch pipe (54), which drives the rotating main pipe (52) to rotate and gradually tightens the coil spring (55). When the spray bar (7) moves closer to the outer frame (51), the coil spring (55) gradually relaxes, rotates the rotating main pipe (52) to reset, and rewinds the branch pipe (54). S5: During the fire extinguishing drill, the feed pipe (53) is connected to the external fire extinguishing device pipeline. The external fire extinguishing device delivers the extinguishing agent through the feed pipe (53) to the inside of the rotating main pipe (52). The rotating main pipe (52) delivers the extinguishing agent to multiple branch pipes (54). The branch pipes (54) deliver the extinguishing agent to the inside of the spray bar (7) and spray the extinguishing agent downward through the nozzle (73) to carry out fixed-point fire extinguishing.
