Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and more specifically, to automatic fire sprinkler systems. Background Technology

[0002] With the continuous expansion of modern building scale and the increasing number of densely populated places, fire safety issues are receiving more and more attention. Taking large-scale warehousing and logistics centers as an example, with the rapid development of the e-commerce logistics industry, individual warehouses often cover tens of thousands of square meters, with floor heights typically reaching 8-15 meters. These warehouses are densely packed with large quantities of flammable materials such as cardboard boxes, plastic products, and textiles. Once a fire breaks out in these high-ceilinged spaces, the fire spreads rapidly, and the complex spatial structure created by the shelving presents a significant challenge to firefighting. Fire sprinkler systems, as the main fixed firefighting facilities in such places, are crucial to the safety of warehousing and the protection of property.

[0003] Currently, fire sprinkler systems used in warehousing and logistics centers primarily employ a ceiling-mounted fixed sprinkler system. The sprinklers are installed at specific intervals on the warehouse ceiling, and area spraying is triggered by smoke or heat sensors. The sprinkler positions and spray angles are fixed during construction, and once the system is activated, it can only spray water downwards over a pre-defined area. Some warehouses also add mid-level sprinklers between shelving levels to try and compensate for blind spots in the top spraying; however, these sprinklers are also fixed and can only cover their respective designated protected areas. When the fire alarm system detects a fire, the sprinklers in the relevant areas activate simultaneously, spraying the entire protected area.

[0004] However, existing fixed sprinkler systems have revealed significant shortcomings in practical applications. Because the mechanical structure of these systems is completely fixed, the sprinkler heads cannot be rotated horizontally to adjust their direction, nor can their spray angle be adjusted vertically. When a fire breaks out on the lower shelves, the water flow from the top sprinklers is often blocked by the upper shelves, making it difficult to reach the actual ignition point. Furthermore, when the fire is located deep within the shelves or in a narrow passage between two rows of shelves, the fixed-angle water flow is even less effective at covering the fire. This rigid limitation in the mechanical structure prevents the sprinkler flow from being adjusted according to the actual location of the fire source, reducing firefighting efficiency and causing severe water damage, becoming a pressing technical problem that needs to be solved in the fire protection field.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The novel and compact structure fundamentally changes the limitation of traditional fire sprinklers that cannot adjust the spray direction due to their fixed structure.

[0030] By setting up a first adjustment component and a second adjustment component driven by a motor and using a worm gear transmission, the spray direction of the fire sprinkler head can be adjusted over a wide range in both horizontal and vertical dimensions, thus enabling it to spray around obstacles such as tall shelves.

[0031] By placing the pressurized sprinkler assembly near the end of the regulating pipe and designing radial water distribution blades and spiral atomizing blades inside the fire sprinkler head, the structure ensures that the water flow can be effectively pressurized and fully atomized before being sprayed, thereby improving the physical range and coverage of the sprayed water flow.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0044] According to an embodiment of the present invention, an automatic fire sprinkler system is provided.

[0045] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the automatic fire sprinkler system according to an embodiment of the present invention includes:

[0046] Conical base 1, used for connection to external fire water supply pipes;

[0047] The first adjustment component 2 is located at the end of the conical base 1 and is used to drive the connecting pipe 4 to rotate and adjust in the horizontal direction.

[0048] Connecting pipe 4 is located at the end of the first adjusting component 2, used to connect the first adjusting component 2 and the second adjusting component 6, and serves as a water inlet channel;

[0049] The detection control box 5 is fixedly installed on one side of the connecting pipe 4, and is used to receive external detection signals and control the overall operation of the equipment;

[0050] The second adjustment component 6 is mounted on the conical base 1 and is used to drive the adjustment tube 8 to adjust the vertical pitch angle.

[0051] The regulating pipe 8 is located at one end of the second regulating component 6 and is used to connect the second regulating component 6 with the fire sprinkler head 10, and also serves as a water outlet channel.

[0052] Fire sprinkler head 10 is installed at the end of regulating pipe 8 and is used to atomize water flow and spray it to a designated area;

[0053] The power supply assembly 13 includes several conduits 1301, a first adapter 1302, and a second adapter 1303;

[0054] The first adjustment component 2 is provided with a first adapter 1302 coaxial with the rotation central axis of the first adjustment component 2; one end of the first adapter 1302 is connected to the detection control box 5 through a conduit 1301;

[0055] A second adapter 1303 is provided at the adjusting pipe 8, which is coaxially arranged with the rotation axis of the second adjusting component 6.

[0056] The first adapter 1302 is connected to the second adapter 1303 through a conduit, and the first adapter 1302 is connected to the second adjusting component 6 through a conduit; the second adapter 1303 is connected to the control component of the fire sprinkler head 10.

[0057] The first adapter 1302 includes a movable connector and a fixed connector connected together, with the movable connector located on the side closer to the first adjusting assembly 2; the second adapter 1303 also includes a movable connector and a fixed connector connected together, with the fixed connector located on the side closer to the second adjusting assembly 6.

[0058] The pressurized sprinkler assembly 9 is located on one side of the fire sprinkler head 10 and is used to pressurize the water flow entering the fire sprinkler head 10 to increase the spray distance and impact force.

[0059] It should be noted that a solenoid valve is installed on the inner side of the connection between the bottom end of the conical base 1 and the external fire water supply pipeline via the base flange 12. This solenoid valve is electrically connected and controlled by the detection and control box 5 through control lines. When the detection and control box 5 receives a fire signal, it first sends an opening command to the solenoid valve, which opens to allow high-pressure water from the main fire water supply network to enter the conical base 1. Subsequently, the detection and control box 5 sends control commands to the first motor 3 and the second motor 7, driving the first regulating component 2 and the second regulating component 6 to perform positioning adjustment. After adjustment, the water flows through the confirmed path to the fire sprinkler head 10, achieving precise spraying. The solenoid valve plays a role in controlling the total flow in the entire system, ensuring that water resources are not wasted before the fire source is accurately located, and also protecting the sprinkler equipment pipeline from prolonged high-pressure impact. This is existing technology and will not be elaborated further here.

[0060] In one embodiment, the first adjustment component 2 and the second adjustment component 6 have the same structure; a first motor mounting base is provided on one side of the first adjustment component 2, and a first motor 3 for driving the first adjustment component 2 to rotate horizontally is provided at one end of the first motor mounting base; a second motor mounting base is provided on one side of the second adjustment component 6, and a second motor 7 for driving the second adjustment component 6 to rotate pitch is provided at one end of the second motor mounting base.

[0061] In one embodiment, a water inlet channel is provided in the middle of the conical base 1, and a waterproof gasket 11 is provided on the outside of the water inlet channel; a base flange 12 is welded to the outside of one end of the conical base 1, and the base flange 12 is fixedly connected to the flange of the external fire water supply pipe by several bolts.

[0062] In one embodiment, the first adjustment component 2 includes a rotating seat 201 disposed at the end of the conical base 1. A rotating core 202 is disposed on the inner side of the rotating seat 201. A water outlet adapter 203 is disposed on the inner side of the end of the rotating core 202 and is fixedly connected to the connecting pipe 4 through a flange. An annular worm gear 204 is fixedly disposed on the outer side of the bottom of the rotating core 202. A worm 205 that meshes with the annular worm gear 204 is disposed on one side inside the rotating seat 201. One end of the worm 205 is fixedly connected to the output end of the first motor 3, and the other end of the worm 205 is connected to the inner wall of the rotating seat 201 through a bearing.

[0063] In practical applications, when the first motor 3 is working, the meshing transmission between the worm gear 205 and the annular worm wheel 204 drives the rotating core 202 and the water outlet adapter 203 fixed thereto to rotate horizontally relative to the rotating seat 201, thereby achieving 360-degree adjustment without dead angles.

[0064] In one embodiment, the top of the water outlet adapter 203 is provided with an installation groove, in which a first friction washer 206 that mates with the connecting pipe 4 is provided; the top of the rotating core 202 is provided with an annular groove, in which a second friction washer 208 that mates with the water outlet adapter 203 is provided on the inner side, and a first annular sealing ring 207 that fits against the inner wall of the rotating core 202 is provided at the bottom outer side of the water outlet adapter 203; an annular snap-fit ​​groove that mates with the conical base 1 is provided at the bottom inner side of the rotating core 202, and a second annular sealing ring 210 is provided at the bottom of the annular snap-fit ​​groove; and an annular step that mates with the rotating seat 201 is provided at the top of the annular step, in which a fixing groove is provided, and a third friction washer 209 that fits against the rotating seat 201 is provided.

[0065] In practical applications, the multiple sealing and friction-reducing structures in this application work together to ensure the stability of the equipment under complex operating conditions. The waterproof gasket 11 on the conical base 1, the first annular sealing ring 207 between the water outlet adapter 203 and the rotating core 202, and the second annular sealing ring 210 between the rotating core 202 and the conical base 1 together constitute a complete dynamic water circuit sealing system. Their core function is to effectively prevent high-pressure water in the fire main pipe from leaking through the mating gap between the rotating core 202, the rotating seat 201, and the conical base 1 when the equipment rotates horizontally, ensuring that the water pressure is not lost and preventing water stains from damaging electrical components such as the motor 3.

[0066] The first friction washer 206, located between the water outlet adapter 203 and the connecting pipe 4; the second friction washer 208, located between the rotating core 202 and the water outlet adapter 203; and the third friction washer 209, located between the rotating core 202 and the rotating seat 201, primarily serve to reduce friction, absorb vibration, and assist in positioning. In practical applications, these friction washers can be made of self-lubricating and wear-resistant materials such as polytetrafluoroethylene (PTFE). Distributed between relatively moving metal parts, they ensure that the first adjusting assembly 2 and the second adjusting assembly 6 can start and stop smoothly under motor drive, thereby reducing the motor load and extending the service life of the spray equipment.

[0067] The working principle of the first adjustment component 2 is as follows: When the detection and control box 5 receives a fire signal and determines the horizontal orientation, its built-in microcontroller sends a command to the first motor 3. The first motor 3 starts and drives the worm gear 205 connected to its output end to rotate. Since the worm gear 205 meshes with the annular worm wheel 204 fixed at the bottom of the rotating core 202, the rotation of the worm gear will drive the annular worm wheel 204 to rotate. As the core rotating component, the rotating core 202 is rigidly connected to the water outlet adapter 203, the connecting pipe 4 and all the components above (including the second adjustment component 6, the adjustment pipe 8, the fire sprinkler head 10, etc.). Therefore, the rotation of the rotating core 202 will drive the entire upper sprinkler structure to rotate horizontally relative to the fixed conical base 1 and the rotating seat 201. Water enters from the conical base 1, passes through the internal channel of the rotating core 202, and finally flows to the water outlet adapter 203. The reliability of the dynamic seal is ensured by multiple sealing rings throughout the process to prevent water leakage. Thus, by controlling the rotation angle and direction of the first motor 3, the fire sprinkler head 10 can be accurately positioned 360° in the horizontal plane.

[0068] The second adjusting component 6 has the same structure as the first adjusting component 2. Its working principle is as follows: After the detection and control box 5 determines the vertical angle of the fire source, its microcontroller sends a command to the second motor 7. The second motor 7 starts and drives its internal worm gear mechanism (corresponding to 204 and 205 in the first adjusting component 2). This transmission mechanism drives the adjusting pipe 8 and the fire sprinkler head 10 to pitch and rotate around the horizontal axis at the end of the connecting pipe 4. Water flows from the connecting pipe 4 through the internal rotation channel of the second adjusting component 6 and finally enters the adjusting pipe 8. Therefore, by controlling the rotation of the second motor 7, the fire sprinkler head 10 can be adjusted vertically to ensure that the water flow can overcome obstacles and accurately hit the fire source at different heights with the optimal parabolic trajectory.

[0069] It should be noted that the booster sprinkler assembly 9 includes a booster pump fixedly installed on one side of the fire sprinkler head 10. The water inlet end of the booster pump is connected to one end of the regulating pipe 8 through a pipe, and the water outlet end on one side of the booster pump is connected to one side of the fire sprinkler head 10 through a pipe. It is used to boost the water flow for a second time when the normal water pressure is insufficient or when a strong spray is needed to penetrate obstacles such as shelves, so as to ensure that the water flow can effectively reach the fire source.

[0070] It should also be noted that the first motor 3, the second motor 7, and the booster pump are all electrically connected to the detection control box 5 via cables. The detection control box 5 is also connected to the external smoke sensor via wired or wireless communication. The detection control box 5 has a built-in microcontroller and drive circuit. When the external smoke sensor, flame detector, or temperature sensor detects a fire signal and sends it to the detection control box 5, the microcontroller in the detection control box 5 precisely controls the rotation of the first motor 3 and the second motor 7 according to a preset program or fire source positioning algorithm, aligns the fire sprinkler head 10 with the fire source, and starts the booster pump as needed, thereby achieving automatic, precise, and efficient spraying and extinguishing of the fire source.

[0071] In one embodiment, the fire sprinkler head 10 includes a nozzle 1001 disposed at the top of the regulating pipe 8. A plurality of radially distributed water-dividing blades 1002 are fixedly disposed on one side of the nozzle 1001. A first central nozzle 1003 is disposed on one side of the plurality of radially distributed water-dividing blades 1002. A second central nozzle 1004 is fixedly disposed at one end of the first central nozzle 1003, and the diameter of the second central nozzle 1004 is smaller than the diameter of the first central nozzle 1003. A plurality of circumferentially distributed spiral atomizing blades 1005 are fixedly disposed on the outer side of the second central nozzle 1004.

[0072] The working principle of the fire sprinkler head 10 is as follows: High-pressure water from the regulating pipe 8 or the booster pump first enters the nozzle 1001 and impacts several radial water-dividing blades 1002 installed inside. These blades initially divide the concentrated water column into multiple streams and guide them to converge towards the center, playing a role in initial rectification and beam splitting. Subsequently, these split water streams enter the narrowing channel formed by the first central nozzle 1003 and the second central nozzle 1004. According to the principles of fluid mechanics, the water flow is accelerated here. Finally, the accelerated water flow impacts the spiral atomizing blades 1005 set on the outside of the second central nozzle 1004. These blades with a specific spiral angle impart a strong rotational tangential velocity to the water flow. Under the combined action of centrifugal force and high-speed axial velocity, the water flow can be rapidly broken and atomized when leaving the nozzle, forming a cone-shaped water mist with a large coverage area and strong penetration, which greatly increases the contact area between water and flame, thereby achieving a highly efficient fire sprinkler extinguishing effect.

[0073] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0074] In practical applications, taking a large warehousing center as an example, when a fire occurs at the bottom of a shelf, smoke sensors or flame detectors installed nearby will immediately detect the fire and send a signal containing the location information of the fire source to the detection control box 5. After receiving the signal, the microcontroller in the detection control box 5 quickly resolves the coordinates of the fire source according to a preset positioning algorithm and immediately sends control commands to the first motor 3 and the second motor 7. The first motor 3 drives the first adjusting component 2 to rotate horizontally, causing the connecting pipe 4 and above to quickly align with the horizontal position of the fire source. At the same time, the second motor 7 drives the second adjusting component 2 to rotate horizontally. The section component 6 is tilted to allow the regulating pipe 8 and the fire sprinkler head 10 to tilt downwards, accurately aiming at the bottom fire point that is obscured by the upper shelf. At the same time as the sprinkler head completes aiming, the main fire valve is opened, and the water flow is delivered to the end through the channel formed by the conical base 1, the first regulating component 2, the connecting pipe 4, the second regulating component 6 and the regulating pipe 8. The detection and control box 5 determines whether it is necessary to activate the booster sprinkler component 9 to boost the water flow a second time based on the size of the fire and the distance. Finally, the fire sprinkler head 10 sprays a strong water flow accurately to the core area of ​​the fire source, achieving targeted extinguishing and effectively preventing the fire from spreading.

[0075] like Figure 6 As shown, a rigid conduit connector for an automatic fire sprinkler system includes a movable connector 14 and a fixed connector 15 connected together. The rotation axis of the movable connector 14 is coaxial with the rotation axis of the corresponding rotating component on the sprinkler system. The fixed connector 15 includes a first connecting part 1501 connected to the fixed side rigid conduit and a receiving part 1502 that cooperates with the movable connector 14. The receiving part 1502 is provided with a stepped hole, and the outer side of the first connecting part 1501 is provided with a connecting thread.

[0076] The movable connector 14 includes a second connecting part 1401 connected to the rotating side through-tube. The outer side of the second connecting part 1401 is provided with connecting threads. The second connecting part 1401 is provided with a fitting part, which includes an annular force-applying boss 1402, an annular positioning boss 1403, and a fitting section 1404 embedded in the receiving part. The outer wall of the fitting section 1404 is provided with an annular groove, and an annular sealing ring 16 is provided in the annular groove. The annular positioning boss 1403 mates with the opening of the stepped hole of the receiving part. A sealing gasket 17 is provided between the annular positioning boss 1403 and the opening of the stepped hole of the receiving part 1502. A gap is provided between the force-applying boss 1402 and the annular positioning boss 1403 for setting a fixed connecting piece.
