Linkage type automatic fire-fighting spraying structure

Abstract

This application relates to the field of indoor fire protection technology, specifically a linkage-type automatic sprinkler system. This application involves installing an adjusting mechanism at the bottom of the main water supply pipe at each outlet branch pipe, and mounting sprinkler components on a movable base. During indoor fire suppression, the adjusting mechanism allows the sprinkler components to move back and forth, avoiding dead zones between adjacent sprinkler components and improving fire suppression efficiency. Simultaneously, by installing a bypass component between adjacent outlet branch pipes on the main water supply pipe, water can be ensured to flow normally to the subsequent sprinkler components even if a blockage occurs between adjacent sprinkler components. This prevents the sprinkler components behind the main water supply pipe from failing to spray water properly due to blockage, thus improving the safety of the fire suppression system.

Description

Technical Field

[0001] This application relates to the field of indoor fire protection technology, and in particular to a linkage-type automatic fire sprinkler structure. Background Technology

[0002] Indoor fire protection systems are a crucial component in protecting people and property inside buildings from fire hazards. They comprise a range of facilities, equipment, and technologies used to promptly detect fires, effectively extinguish them, evacuate people, and minimize fire damage. Automatic sprinkler systems are an indispensable part of indoor fire protection systems.

[0003] The existing indoor automatic sprinkler system mainly consists of a water supply main, sprinkler heads installed at the outlet at the bottom of the water supply main, and a smoke alarm sensor installed on one side of the sprinkler heads. When this type of automatic sprinkler system is in use, the smoke alarm sensor first detects the smoke in the room and sends an alarm message to the remote control terminal in the event of a fire. At the same time, fire-fighting water is supplied to the sprinkler heads through the water supply main to extinguish the fire in the room.

[0004] While existing indoor automatic sprinkler systems can extinguish fires by automatically spraying water, they suffer from several drawbacks. First, the fixed installation positions of each sprinkler head create blind spots between adjacent heads, resulting in low fire extinguishing efficiency. Second, since all sprinkler heads share a single water supply pipe, blockages in the pipe between adjacent heads can prevent the sprinkler heads downstream from spraying water properly, posing significant safety hazards to the fire extinguishing system. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a linkage-type automatic fire sprinkler structure that can avoid spray dead zones between adjacent sprinkler heads by reciprocating movement, and can ensure the normal use of each sprinkler head when the section of the water supply main pipe between adjacent sprinkler heads is blocked.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] An automatic fire sprinkler system includes a main water supply pipe, with branch pipes installed at the outlet of the bottom of the main water supply pipe. An adjusting mechanism is located below each branch pipe at the bottom of the main water supply pipe. A hanger rod is connected to each side of the top of the adjusting mechanism and the main water supply pipe. The adjusting mechanism includes a motor, an adjusting frame, a screw, and a movable base. The adjusting frame is connected to the bottom of the hanger rod, the movable base is located within the adjusting frame, the screw is located on one inner side wall of the adjusting frame, and the motor is installed on one outer side wall of the adjusting frame, directly opposite the screw. A sprinkler assembly is mounted on the movable base. The system includes a spray head, a spray pipe, and a connecting hose. The spray pipe is installed in the middle of the movable base, and the connecting hose is installed between the top of the spray pipe and the bottom of the outlet branch pipe. The spray head is installed at the bottom of the spray pipe. A bypass assembly is also installed at the top of the main water supply pipe between two adjacent spray components. The bypass assembly includes a bypass pipe, a one-way inlet valve, and a one-way outlet valve. Both ends of the bypass pipe are connected to the inside of the main water supply pipe. The one-way inlet valve is installed at the inlet of the bypass pipe, and the one-way outlet valve is installed at the outlet of the bypass pipe. A smoke alarm sensor is also installed on one side of the bottom of the adjusting frame.

[0008] Optionally, a guide assembly is also installed between the movable seat and the adjusting frame. The guide assembly includes a guide groove and a guide block.

[0009] Optionally, the guide block is formed on the movable seat, and the guide block slides in conjunction with the guide groove.

[0010] Optionally, the movable seat is slidably engaged with the adjusting frame, and the screw is rotatably engaged with the guide groove.

[0011] Optionally, the motor is connected to the screw coupling, and the screw passes through one of the guide blocks and is threadedly engaged with the corresponding guide block.

[0012] Optionally, the spray pipe has an inverted T-shaped structure, and the spray pipe passes through the movable seat and is bolted to the movable seat.

[0013] Optionally, the spray head is threadedly connected to the spray pipe, and the connecting hose is a telescopic structure.

[0014] Optionally, the bypass pipe has an inverted U-shaped structure and is welded to the main water supply pipe.

[0015] Optionally, both the one-way inlet valve and the one-way outlet valve are bolted to the bypass pipe.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This invention features an adjustment mechanism installed at the bottom of the main water supply pipe at each outlet branch pipe. This mechanism comprises a motor, an adjustment frame, a screw, and a moving base. A spray assembly consisting of a connecting hose, a spray pipe, and a spray head is mounted on the moving base. During indoor fire suppression, the adjustment mechanism allows the spray assembly to move back and forth, preventing dead zones between adjacent spray assemblies and improving fire suppression efficiency. Furthermore, a bypass assembly consisting of a bypass pipe, a one-way inlet valve, and a one-way outlet valve is installed between adjacent outlet branch pipes on the main water supply pipe. This bypass assembly ensures the normal flow of water from the main water supply pipe to the downstream spray assembly when blockage occurs between adjacent spray assemblies. This prevents the downstream spray assembly from failing to spray properly due to blockage, thus improving the safety of the fire suppression system. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] To better understand the technical solutions presented in the embodiments of this application, the composition and working principle of existing indoor linkage automatic fire sprinkler structures will first be introduced.

[0025] The existing indoor automatic sprinkler system mainly consists of a water supply main, sprinkler heads installed at the outlet at the bottom of the water supply main, and a smoke alarm sensor installed on one side of the sprinkler heads. When this type of automatic sprinkler system is in use, the smoke alarm sensor first detects the smoke in the room and sends an alarm message to the remote control terminal in the event of a fire. At the same time, fire-fighting water is supplied to the sprinkler heads through the water supply main to extinguish the fire in the room.

[0026] Please see Figures 1-4 This application discloses a linkage-type automatic fire sprinkler structure, including a main water supply pipe 2. A branch water pipe 1 is installed at the outlet of the bottom of the main water supply pipe 2. An adjusting mechanism 4 is installed below each branch water pipe 1 at the bottom of the main water supply pipe 2. A hanger rod 3 is connected to both sides of the top of the adjusting mechanism 4 and the main water supply pipe 2. The adjusting mechanism 4 includes a motor 41, an adjusting frame 42, a screw 43, and a movable seat 44. The adjusting frame 42 is connected to the bottom of the hanger rod 3, the movable seat 44 is located within the adjusting frame 42, the screw 43 is located on one inner side wall of the adjusting frame 42, and the motor 41 is installed on one outer side wall of the adjusting frame 42, directly opposite the screw 43. A sprinkler assembly 5 is installed on the movable seat 44. Component 5 includes a spray head 51, a spray pipe 52, and a connecting hose 53. The spray pipe 52 is installed in the middle of the movable base 44, and the connecting hose 53 is installed between the top of the spray pipe 52 and the bottom of the outlet branch pipe 1. The spray head 51 is installed at the bottom of the spray pipe 52. A bypass component 7 is also installed at the top of the main water supply pipe 2 between two adjacent spray components 5. The bypass component 7 includes a bypass pipe 71, a one-way inlet valve 73, and a one-way outlet valve 72. Both ends of the bypass pipe 71 are connected to the inside of the main water supply pipe 2. The one-way inlet valve 73 is installed at the inlet of the bypass pipe 71, and the one-way outlet valve 72 is installed at the outlet of the bypass pipe 71. A smoke alarm sensor 8 is also installed on one side of the bottom of the adjusting frame 42.

[0027] Specifically, when the smoke alarm sensor 8 detects smoke indoors, it sends a warning message to the fire control center and simultaneously issues an alarm. Water is then supplied to the main water supply pipe 2 via the fire protection system. After entering the main water supply pipe 2, the fire-fighting water is delivered to the connecting hose 53 via the branch pipe 1. The fire-fighting water in the connecting hose 53 is ultimately sprayed into the room via the sprinkler pipe 52 and sprinkler head 51 to extinguish the fire. During the fire-fighting process, the screw 43 rotates under the action of the motor 41, causing the movable seat 44 to slide back and forth along the adjusting frame 42 under the action of the threaded transmission. The reciprocating movement of the movable seat 44 synchronizes the movement of the sprinkler assembly 5. The system moves back and forth, enabling mobile sprinkler fire suppression indoors. This avoids dead zones between adjacent sprinkler components 5 during fire suppression, resulting in higher efficiency in indoor fire suppression. Simultaneously, in conjunction with the bypass component 7, which consists of a bypass pipe 71, a one-way inlet valve 73, and a one-way outlet valve 72, it ensures the normal flow of water from the main water supply pipe 2 to the subsequent sprinkler components 5 when a blockage occurs between adjacent sprinkler components 5. This prevents the sprinkler components 5 behind the main water supply pipe 2 from failing to spray water for fire suppression due to blockage, thus improving the safety of the fire suppression system.

[0028] Please see Figure 3 A guide assembly 6 is also installed between the movable seat 44 and the adjusting frame 42. The guide assembly 6 includes a guide groove 61 and a guide block 62.

[0029] In one implementation, the guide block 62 cooperates with the guide groove 61 to ensure the stable movement of the movable seat 44 within the adjustment frame 42 and to ensure that the movable seat 44 will not fall out of the adjustment frame 42.

[0030] Please see Figure 3 The guide block 62 is formed on the movable seat 44, and the guide block 62 slides in conjunction with the guide groove 61.

[0031] As one implementation method, the sliding fit installation method makes the movement and adjustment of the movable seat 44 relative to the adjustment frame 42 more convenient.

[0032] Please see Figure 1 and Figure 3 The movable seat 44 is slidably engaged with the adjusting frame 42, and the screw 43 is rotatably engaged with the guide groove 61.

[0033] As one implementation method, the rotational fit installation method makes the rotation of the screw 43 relative to the guide groove 61 more convenient, ensuring that the moving seat 44 can be moved and adjusted under the action of thread transmission after the screw 43 rotates.

[0034] Please see Figure 1 and Figure 3 The motor 41 is connected to the screw 43 by a coupling, and the screw 43 passes through one of the guide blocks 62 and is threadedly engaged with the corresponding guide block 62.

[0035] In one implementation, the motor 41 is mainly used to provide power for the rotation of the screw 43, and the motor 41 is a three-phase motor that can rotate in both directions to achieve the adjustment of the forward and reverse rotation of the screw 43.

[0036] Please see Figure 1 and Figure 4 The spray pipe 52 has an inverted T-shaped structure, and the spray pipe 52 passes through the movable seat 44 and is bolted to the movable seat 44.

[0037] As one implementation method, the bolted connection installation method makes the spray pipe 52 more firmly fixed on the movable seat 44, and the top of the spray pipe 52 passes through the movable seat 44.

[0038] Please see Figure 1 and Figure 4 The spray head 51 is threadedly connected to the spray pipe 52, and the connecting hose 53 is a telescopic structure.

[0039] As one implementation method, the threaded connection can reliably install the spray head 51 on the spray pipe 52, and also facilitates the convenient disassembly and maintenance of the spray head 51 in the future. The telescopic connecting hose 53 can ensure that the water outlet branch pipe 1 delivers water normally to the spray pipe 52 when the spray pipe 52 moves.

[0040] Please see Figures 1-2 The bypass pipe 71 has an inverted U-shaped structure and is welded to the main water supply pipe 2.

[0041] As one implementation method, the bypass pipe 71 mainly serves as a bypass to ensure that when the main water supply pipe 2 is partially blocked between two adjacent spray assembly 5, water can be normally transported to the subsequent spray assembly 5 through the bypass pipe 71.

[0042] Please see Figure 2 Both the one-way inlet valve 73 and the one-way outlet valve 72 are bolted to the bypass pipe 71.

[0043] As one implementation method, the one-way inlet valve 73 and the one-way outlet valve 72 can ensure the one-way flow of water in the bypass pipe 71 and prevent the backflow of fire-fighting water.

[0044] The specific working principle is as follows: First, the main water supply pipe 2 is installed in the corresponding fire-fighting location indoors, and the linkage-type automatic fire sprinkler structure is connected to the indoor fire control system. Then, the linkage-type automatic fire sprinkler structure can be put into use. During use, when the smoke alarm sensor 8 detects smoke indoors, it will send a warning message to the fire control center and issue an alarm. At the same time, water will be supplied to the main water supply pipe 2 through the fire system. After the fire-fighting water enters the main water supply pipe 2, it will be transported to the connecting hose 53 through the outlet branch pipe 1. The fire-fighting water in the connecting hose 53 will finally be sprayed into the room through the sprinkler pipe 52 and the sprinkler head 51 to achieve fire extinguishing in the room. During the fire extinguishing process, the screw 43 is rotated under the action of the motor 41, which can be driven by the threaded transmission. Under the action, the movable seat 44 slides back and forth along the adjusting frame 42. During the reciprocating movement of the movable seat 44, the sprinkler assembly 5 moves back and forth synchronously, thereby realizing mobile sprinkler fire extinguishing in the room. This avoids the presence of spray dead zones between adjacent sprinkler assemblies 5 during fire extinguishing, making the indoor fire extinguishing efficiency higher. At the same time, in conjunction with the bypass assembly 7, which consists of a bypass pipe 71, a one-way inlet valve 73, and a one-way outlet valve 72, when the water supply main pipe 2 is partially blocked between two adjacent sprinkler assemblies 5, the bypass assembly 7 can ensure the normal delivery of water from the water supply main pipe 2 to the subsequent sprinkler assembly 5. This avoids the sprinkler assembly 5 behind the water supply main pipe 2 being unable to spray water for fire extinguishing due to partial blockage between two adjacent sprinkler assemblies 5, thus improving the safety of the fire extinguishing system.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
