Description

Technical Field

[0001] This utility model belongs to the field of fire sprinkler technology, and specifically relates to a fire sprinkler device with rapid positioning. Background Technology

[0002] Fire sprinkler systems are ubiquitous in all types of buildings, from densely populated shopping malls, schools, and office buildings to warehouses storing large quantities of goods and residential homes where residents live their daily lives, building a solid line of defense to protect lives and property.

[0003] In most cases, the sprinkler system relies on a temperature sensing element or smoke detector at the nozzle to trigger its action. Once the environmental parameters reach the set threshold, the nozzle will start spraying water. However, this method can only detect the fire situation near the nozzle and cannot accurately locate the specific location of the fire source. It cannot concentrate its efforts on effectively extinguishing the fire source, resulting in low fire extinguishing efficiency. On the other hand, the water deflector plate equipped with the nozzle of the existing fire sprinkler system was originally intended to distribute the sprayed water evenly and expand the fire extinguishing coverage area. However, in actual fire scenarios, when the fire source is exactly in the vertical direction of the water deflector plate, the water flow will be blocked by the water deflector plate and will be difficult to directly act on the fire source, thus forming a fire extinguishing dead zone.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a rapid positioning fire sprinkler device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a rapid positioning fire sprinkler device, comprising a yoke arm base, multiple yoke arm frames fixedly mounted at the bottom of the yoke arm base, support columns fixedly mounted at the bottom of the multiple yoke arm frames, a nozzle connected to the bottom of the yoke arm base, a splash plate fixedly mounted at the bottom of the support columns, the splash plate having multiple toothed ridges, a connecting threaded pipe connected to the top of the yoke arm base, a water outlet cavity formed inside the support columns, a water distribution component inside the water outlet cavity, the lower part of the water distribution component invertedly resting on the bottom of the splash plate, an angle drive component on the top of the yoke arm base, a rotating connection mechanism on the top of the angle drive component, a power mechanism engaged inside the rotating connection mechanism, a base mounting plate on the top of the power mechanism, and a telescopic pipe connected to the top of the connecting threaded pipe, the telescopic pipe passing through the base mounting plate and extending above it.

[0008] Furthermore, the water distribution assembly includes a rotating shaft, which is rotatably mounted on the support column. One end of the rotating shaft and located inside the water outlet cavity is provided with a micro impeller, and the other end of the rotating shaft and located below the splash plate is provided with a hollowed-out truncated cone.

[0009] Furthermore, the top of the hollowed-out truncated cone is inverted on the bottom of the splash plate, and a plurality of first water outlet holes in a circular array are opened on the inclined side of the hollowed-out truncated cone, and a plurality of second water outlet holes are opened on the bottom of the hollowed-out truncated cone.

[0010] Furthermore, the power mechanism includes a power motor, which is fixedly mounted on the base mounting plate. A power shaft is fixedly mounted on the output end of the power motor, and a rotating gear is fixedly mounted on the other end of the power shaft.

[0011] Furthermore, the rotating connection mechanism includes a housing, which is rotatably mounted on the base mounting plate. A fixed gear disk is fixedly installed at the bottom of the inner cavity of the housing, and the rotating gear meshes with the fixed gear disk. Support rods are symmetrically fixed at the bottom of the housing.

[0012] Furthermore, the angle driving assembly includes a drive motor, which is fixedly mounted on one of the two support rods. The angle driving assembly also includes two connecting brackets, both of which are fixedly mounted on the top of the yoke arm seat.

[0013] Furthermore, the two connecting frames are respectively hinged to the two supporting rods, and one of the connecting frames is fixedly installed on the output shaft of the drive motor.

[0014] Compared with the closest prior art, this utility model has the following advantages:

[0015] In terms of water supply, this utility model connects fire-fighting water to the threaded pipe via a telescopic pipe. The telescopic pipe can be adjusted according to the angle of components such as the yoke arm seat, yoke arm frame, and support column to ensure a stable water supply. After entering the threaded pipe, the water flows into the yoke arm seat and then into the nozzle. Part of the water flows into the outlet chamber inside the support column. In the outlet chamber, the water flow impacts the water distribution component, causing it to rotate. The rotating water distribution component rationally distributes the water flow, ensuring that the water flows evenly through the water distribution component to extinguish the fire source below the splash plate. This eliminates the fire-extinguishing dead zone in the vertical direction of the splash plate in traditional devices, ensuring that the fire source can be effectively impacted by the water flow regardless of its location, greatly improving the fire-extinguishing efficiency. Another part of the water impacts the splash plate, where multiple toothed ridges change the direction of the water flow, causing the water flow to be evenly distributed in a scattering pattern, effectively expanding the fire-extinguishing coverage area.

[0016] The positioning information of this utility model is also transmitted to the angle drive component. The power mechanism is also equipped with a motor. When the positioning signal is received from the intelligent analysis and linkage controller, the control circuit of the motor is turned on and starts to run, causing the angle drive component to work. The angle drive component drives the yoke arm seat, yoke arm frame, support column, nozzle, splash plate and water distribution component to adjust the angle around the connection point between the angle drive component and the rotating connection mechanism. With the cooperation of the power mechanism and the angle drive component, the nozzle, splash plate, water distribution component and other components can accurately align with the fire source position and complete the water spray preparation after accurate positioning.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-7 As shown, this utility model is a rapid positioning fire sprinkler device, including a yoke arm seat 1. Multiple yoke arm frames 2 are fixedly installed at the bottom of the yoke arm seat 1. Support columns 3 are fixedly installed at the bottom of the multiple yoke arm frames 2. A nozzle 4 is connected to the bottom of the yoke arm seat 1. A splash plate 6 is fixedly installed at the bottom of the support column 3. Multiple toothed ridges 601 are formed on the splash plate 6. A connecting threaded pipe 13 is connected to the top of the yoke arm seat 1. A water outlet chamber 7 is formed inside the support column 3. A water distribution component 8 is provided inside the water outlet chamber 7. The lower part of the water distribution component 8 is inverted and placed on the bottom of the splash plate 6. An angle drive component 9 is provided at the top of the yoke arm seat 1. A rotating connection mechanism 10 is provided at the top of the angle drive component 9. A power mechanism 11 is engaged inside the rotating connection mechanism 10. A base mounting plate 12 is provided at the top of the power mechanism 11. A telescopic pipe 14 is connected to the top of the connecting threaded pipe 13. The telescopic pipe 14 passes through the base mounting plate 12 and extends above it.

[0031] The preceding intelligent detection controller has multiple detection functions, including smoke, temperature and flame detection, and infrared and ultraviolet dual-band detection. By monitoring environmental parameters in all directions, it can quickly detect signs of fire. The visible light, near-infrared imaging and infrared temperature detection data transmitted by the image-type intelligent fire detector are comprehensively analyzed to achieve accurate location of the fire. The image-type intelligent fire detector is not only resistant to sunlight interference, but can also be connected to a video monitoring system for fire verification to further ensure the accuracy of the location. The location control system in the intelligent analysis linkage controller activates relevant fire extinguishing equipment, including this fire sprinkler system, based on the location results.

[0032] When a fire occurs, the image-type intelligent fire detector and intelligent detection controller are used to quickly and accurately locate the fire source through multiple analyses. The signal is transmitted to the intelligent analysis and control linkage, which then activates the fire extinguishing device. It should be noted that the intelligent detection controller, intelligent detection controller and intelligent analysis linkage controller are existing technologies and are not shown in the figure. The specific installation location can be determined according to actual needs.

[0033] In this device, the positioning information is transmitted to the power mechanism 11. The power mechanism 11 is equipped with a motor. When it receives the positioning signal from the intelligent analysis and linkage controller, the control circuit of the motor is turned on and starts to operate. Since the power mechanism 11 is internally engaged with the rotating connection mechanism 10, the power mechanism 11 will drive the rotating connection mechanism 10 to rotate. The rotating connection mechanism 10 will randomly drive the angle drive component 9, as well as the yoke arm seat 1, yoke arm frame 2, support column 3, nozzle 4, splash plate 6, water distribution component 8 and other components connected to the angle drive component 9 to adjust in the horizontal direction until the nozzle 4, splash plate 6, water distribution component 8 and other components are directly facing the fire source in the horizontal direction.

[0034] At the same time, the positioning information is also transmitted to the angle drive component 9. The power mechanism 11 also has a motor inside. When it receives the positioning signal from the intelligent analysis and linkage controller, the control circuit of the motor is turned on and starts to run, causing the angle drive component 9 to work. The angle drive component 9 drives the yoke arm seat 1, yoke arm frame 2, support column 3, nozzle 4, splash plate 6 and water distribution component 8 to adjust the angle around the connection point between the angle drive component 9 and the rotating connection mechanism 10. With the cooperation of the power mechanism 11 and the angle drive component 9, the nozzle 4, splash plate 6, water distribution component 8 and other components can accurately align with the fire source position and complete the water spray preparation after accurate positioning.

[0035] In terms of water supply, fire water is connected to the threaded pipe 13 through the telescopic pipe 14. The telescopic pipe 14 can be adjusted according to the angle of components such as the yoke arm seat 1, yoke arm frame 2, and support column 3 to ensure stable water supply. After entering the threaded pipe 13, the water flows into the yoke arm seat 1 and then into the nozzle 4. Part of the water flows into the water outlet chamber 7 in the support column 3. In the water outlet chamber 7, the water flow impacts the water distribution component 8, causing it to rotate. The rotating water distribution component 8 distributes the water flow reasonably, so that the water flow passes evenly through the water distribution component 8 to extinguish the fire source below the splash plate 6. This eliminates the fire extinguishing dead angle in the vertical direction of the splash plate 6 in traditional devices, ensuring that the fire source can be effectively impacted by the water flow regardless of its location, greatly improving the fire extinguishing efficiency. Another part of the water impacts the splash plate 6, and the multiple toothed ridges 601 on the splash plate 6 change the direction of the water flow, so that the water flow is evenly distributed in a scattering pattern in all directions, effectively expanding the fire extinguishing coverage area.

[0036] In one embodiment, the water distribution component 8 includes a rotating shaft 801, which is rotatably mounted on the support column 3. One end of the rotating shaft 801 and located inside the water outlet cavity 7 is provided with a micro impeller 802, and the other end of the rotating shaft 801 and located below the splash plate 6 is provided with a hollowed-out frustum 803.

[0037] The top of the hollowed-out truncated cone 803 is inverted on the bottom of the splash plate 6. Multiple first water outlet holes 804 in a circular array are opened on the inclined side of the hollowed-out truncated cone 803, and multiple second water outlet holes 805 are opened on the bottom of the hollowed-out truncated cone 803.

[0038] Firefighting water is connected to the threaded pipe 13 via a telescopic pipe 14. The telescopic pipe 14 can be adjusted according to the angles of components such as the yoke arm seat 1, yoke arm frame 2, and support column 3 to ensure a stable water supply. After entering the threaded pipe 13, the water flows into the yoke arm seat 1, and then into the sprinkler head 4. A portion of the water flows into the outlet chamber 7 inside the support column 3. In the outlet chamber 7, the water flow impacts the micro impeller 802. Since the micro impeller 802 is installed at one end of the rotating shaft 801, and the rotating shaft 801 is rotatably mounted on the support column 3, the impact force of the water flow causes the micro impeller 802 to drive the rotating shaft 801 to rotate. As the rotating shaft 801 rotates, the water flow in the outlet chamber 7... The hollowed-out truncated cone 803 below the splash plate 6 rotates synchronously. The top of the hollowed-out truncated cone 803 is inverted and placed on the bottom of the splash plate 6. Multiple first water outlet holes 804 in a circular array are opened on its inclined side, and multiple second water outlet holes 805 are opened at the bottom. When the water flows through the rotating hollowed-out truncated cone 803, part of the water is sprayed out from the first water outlet hole 804. Under the action of centrifugal force and water pressure, it impacts the area below the splash plate 6 in a scattering manner, effectively making up for the fire extinguishing dead corner below the traditional splash plate 6. Another part of the water is sprayed vertically downward from the second water outlet hole 805, which further enhances the extinguishing effect on the fire source in the vertical direction of the splash plate 6.

[0039] Another portion of the water jet from the nozzle 4 impacts the splash plate 6. The multiple toothed ridges 601 on the splash plate 6 change the direction of the water flow, causing the water to be evenly distributed in a scattering pattern, effectively expanding the fire extinguishing coverage area. Furthermore, through the synergistic effect of the water distribution component 8 and the splash plate 6, it is ensured that the fire source, regardless of its location, can be effectively impacted by the water flow, greatly improving the fire extinguishing efficiency.

[0040] In one embodiment, the power mechanism 11 includes a power motor 1101, which is fixedly mounted on the base mounting plate 12. A power shaft 1102 is fixedly mounted on the output end of the power motor 1101, and a rotating gear 1103 is fixedly mounted on the other end of the power shaft 1102.

[0041] The rotating connection mechanism 10 includes a housing 1001, which is rotatably mounted on the base mounting plate 12. A fixed gear disk 1002 is fixedly mounted at the bottom of the inner cavity of the housing 1001. The rotating gear 1103 meshes with the fixed gear disk 1002. Support rods 1003 are symmetrically fixed at the bottom of the housing 1001.

[0042] The angle driving assembly 9 includes a drive motor 901, which is fixedly mounted on one of the two support rods 1003. The angle driving assembly 9 also includes two connecting brackets 902, which are fixedly mounted on the top of the yoke arm seat 1.

[0043] The two connecting frames 902 are respectively hinged to the two support rods 1003, and one of the connecting frames 902 is fixedly installed on the output shaft of the drive motor 901.

[0044] The positioning information is transmitted to the power motor 1101, which is fixedly mounted on the base mounting plate 12. When the positioning signal is received from the intelligent analysis and linkage controller, the control circuit of the power motor 1101 is turned on, and the power motor 1101 starts to run. The output end of the power motor 1101 drives the fixedly mounted power shaft 1102 to rotate. The rotating gear 1103 fixedly mounted on the other end of the power shaft 1102 rotates synchronously. The housing 1001 is rotatably mounted on the base mounting plate 12. A fixed gear disk 1002 is fixedly mounted at the bottom of its inner cavity. Since the rotating gear 1103 meshes with the fixed gear disk 1002, the rotation of the rotating gear 1103 drives the fixed gear disk 1002, thereby driving the housing 1001 to rotate on the base mounting plate 12. The support rods 1003 symmetrically fixed at the bottom of the housing 1001 also rotate with the housing 1001.

[0045] The drive motor 901 is fixedly mounted on one of the two support rods 1003. The two connecting frames 902 are both fixedly mounted on the top of the yoke arm seat 1 and are respectively hinged to the two support rods 1003. One of the connecting frames 902 is also fixedly mounted on the output shaft of the drive motor 901. When the housing 1001 rotates and drives the support rod 1003 to rotate, the connecting frame 902 hinged to the support rod 1003 also moves accordingly. Then the connecting frame 902 will drive the yoke arm seat 1, yoke arm frame 2, support column 3, nozzle 4, splash plate 6 and hollowed-out truncated cone 803 to rotate, so that these components are aligned with the fire source in the horizontal direction.

[0046] At the same time, the positioning information is also transmitted to the drive motor 901. When the positioning signal is received from the intelligent analysis and linkage controller, the control circuit of the drive motor 901 is turned on and starts to operate. The drive motor 901 starts and its output shaft rotates, driving the connecting frame 902 connected to it to change its angle around the hinge point. Since both connecting frames 902 are connected to the yoke arm seat 1, the other connecting frame 902 moves in coordination under the action of the angle change of one connecting frame 902, thereby driving the yoke arm seat 1 to rotate. This causes the yoke arm seat 1, yoke arm frame 2, support column 3, nozzle 4, splash plate 6 and hollowed-out truncated cone 803 to rotate, adjusting the angle of the connecting frame 902 and support rod 1003 around the axis. Then, under the action of the drive motor 901 and the power motor 1101, the components such as the yoke arm seat 1, yoke arm frame 2, support column 3, nozzle 4, splash plate 6 and hollowed-out truncated cone 803 can be accurately aligned with the fire source position, completing the water spray preparation after precise positioning.
