Description

[0001] This utility model claims priority to "application date: December 31, 2024, application number: 202411993470.2, patent name: a fire extinguishing sprinkler device" and "application date: August 7, 2024, application number: 202411078956.3, patent name: an intelligent household fire extinguisher", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of spray fire extinguishing technology, specifically to a rotatable spray fire extinguishing device. Background Technology

[0003] Automatic sprinkler systems are among the most widely used and effective fixed fire protection facilities in modern building fire protection. Their core function is to detect fires and automatically spray water to extinguish and control initial fires, thereby maximizing the protection of life and property. Traditional automatic sprinkler systems mostly use fixed sprinkler heads. Their working principle involves using heat-sensitive elements (such as glass bulbs or fusible alloys) to activate at a predetermined temperature, opening the seals and allowing pressurized water to be evenly sprayed through the deflector plate, covering the protected area.

[0004] Although fixed sprinkler systems are technologically mature and highly reliable, their coverage area is fixed and limited in practical applications, resulting in low water efficiency. Specifically, the coverage area of ​​traditional automatic sprinkler systems is determined during their design and installation. Each sprinkler head can only protect a relatively fixed circular or rectangular area below it, and the size of the sprinkler range cannot be adjusted, resulting in certain blind spots. In particular, when the fire source is located at the boundary between the protection areas of two sprinklers or far from the center of the sprinkler head, the fire extinguishing efficiency will decrease significantly. Furthermore, during a fire, multiple sprinklers above and around the fire area are often pneumatically activated simultaneously. A large portion of the water sprayed does not reach the base of the fire source but is rapidly evaporated by the temperature of the fire, forming mist. This results in poor fire extinguishing efficiency and high water consumption.

[0005] Therefore, there is a need for a rotating sprinkler fire extinguishing device that can adjust the coverage area, spray at the base of the fire source, and improve fire extinguishing efficiency and water efficiency. Utility Model Content

[0006] The purpose of this invention is to propose a rotatable sprinkler fire extinguishing device that solves the problems of existing sprinkler systems in the background art, such as fixed coverage area, inability to spray at the root of the fire source, and low fire extinguishing efficiency and water efficiency, by adjusting the horizontal and vertical of the fire extinguishing nozzle.

[0035] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] The rotating sprinkler fire extinguishing device of this application can be used in fire extinguishing and other similar applications. The following is a detailed description of the rotating sprinkler fire extinguishing device.

[0037] See appendix Figure 1 — Figure 10 The diagram shows a preferred embodiment of a rotatable sprinkler fire extinguishing device according to this application. The rotatable sprinkler fire extinguishing device includes a first rotating assembly 1, a fire extinguishing medium channel 2 disposed on the first rotating assembly 1, a connecting pipe 3 movably mounted on the first rotating assembly 1 and connected to the fire extinguishing medium channel 2, a second rotating assembly 4 mounted on the first rotating assembly 1, and a nozzle 5 movably mounted on the connecting pipe 3 and connected to the second rotating assembly 4.

[0038] When the first rotating component 1 drives the nozzle 5 to rotate, the plane formed by the movement trajectory of any point on the nozzle 5 is the first plane. When the second rotating component 4 drives the nozzle 5 to rotate, the plane formed by the movement trajectory of any point on the nozzle 5 is the second plane. The second plane is perpendicular to the first plane, and the first plane is perpendicular to the direction of flow of the extinguishing medium in the extinguishing medium channel 2. The nozzle 5 and the end of the connecting pipe 3 are movably connected through a rotary joint, which is existing technology.

[0039] This application utilizes a first rotating component 1 to drive the nozzle 5 to rotate horizontally, allowing the nozzle 5 to face any direction on the horizontal plane and extinguish fires from any location. The extinguishing medium channel 2 provides flow space for the extinguishing medium. The connecting pipe 3 connects the extinguishing medium channel 2 and the nozzle 5, allowing the extinguishing medium to enter the nozzle 5 and be sprayed out for fire extinguishing. The second rotating component 4 drives the nozzle 5 to rotate vertically, adjusting the angle between the nozzle 5 and the horizontal plane, thus adjusting the distance at which the nozzle 5 sprays water, enabling the extinguishing of fires at different distances. It should be noted that the extinguishing medium can be pressurized water; if the pressure is insufficient, a pressure pump can be added.

[0040] See appendix Figure 2 — Figure 6 As shown in this application, the first rotating assembly includes a stator 11, a rotor 12 that rotates around the stator 11 and is disposed on the outer wall of the stator 11, a coil winding 13 wound on the rotor 12 or the stator 11, and a brake 14 mounted on the stator 11 to stop the rotation of the rotor 12. The extinguishing medium channel 2 is disposed on the stator 11 and passes through it. The rotor 12 can drive the nozzle 5 to rotate, and the movement trajectory of any point on the nozzle 5 forms a first plane. The centerline of the stator 11 coincides with the centerline of the rotor 12, and the stator 11 is located on the centerline of the rotor 12. A connecting pipe 3 is connected to the bottom of the rotor 12 and is movably connected to the stator 11. It should be noted that the rotor 12 can be integrally formed with the connecting pipe 3.

[0041] This application ensures that the fire extinguishing medium channel 2 can be positioned in the center and the rotor 12 is positioned on the outside, so that there will be no interference when the nozzle 5 drives the connecting pipe 3 to rotate horizontally. The setting of the brake component 14 can limit the rotor 12 and prevent the rotor 12 from rotating too far due to inertia, so that the rotor 12 can stop in time without the need for frequent horizontal angle adjustments, thus improving the accuracy of rotation control. It should be noted that the brake component 14 can be a hollow magnetic powder electromagnetic brake, which is the prior art, so it will not be described in detail here.

[0042] See appendix Figure 2 — Figure 6As shown in this application, a first housing 6 is connected to the rotor 12, and a through groove 61 is provided on the first housing 6. A second housing 7 is installed on the brake component 14. The first housing 6 and the second housing 7 are movably connected, enclosing and protecting the internal components. The through groove 61 avoids the nozzle 5, so that the extinguishing medium sprayed by the nozzle 5 is not blocked by the housing and can come into contact with the fire source to extinguish the fire. At the same time, since the rotor 12 is connected to the first housing 6, when the rotor 12 rotates, it can drive the first housing 6 to rotate.

[0043] See appendix Figure 4 — Figure 6 As shown in this application, the top of the stator 12 is connected to a fire extinguishing medium inlet pipe 15, and a solenoid valve 16 is installed on the fire extinguishing medium inlet pipe 15. Through the setting of the fire extinguishing medium inlet pipe 15 and the solenoid valve 16, this application can control the flow of the fire extinguishing medium after extinguishing and prevent the fire extinguishing medium from being continuously sprayed out.

[0044] See appendix Figure 7 and Figure 8 As shown in this application, the second rotating component 4 is connected to a connecting plate 43 that is connected to the first rotating component 1; wherein, the second rotating component 4 includes a rotating power source 41 and a reversing structure 42 connected to the rotating power source 41, and the reversing structure 42 is connected to the nozzle 5.

[0045] This application uses a connecting plate 43 to connect the first rotating component 1 and the second rotating component 4, so that the first rotating gripper 1 can drive the second rotating component 4 to rotate and move synchronously horizontally. One end of the connecting plate 43 can be installed on the rotor 12 or the first housing 6 of the first rotating component 1. When the rotor 12 or the first housing 6 rotates, it will transmit power to the second rotating component 4 through the connecting plate 43, driving the second rotating component 4 to rotate synchronously. The rotating power source 41 serves as the power source for the vertical rotation of the nozzle 5. The output direction of the rotating power source 41 can be adjusted and changed by the reversing structure 42, saving installation space. The reversing structure 42 can be a gear reversing device, which is prior art, so it will not be described in detail here.

[0046] See appendix Figure 2 — Figure 8 As shown in this application, a connecting frame 51 is installed on the nozzle 5, a second sensing module 9 is installed on the connecting frame 51, a connecting post is provided on the outer wall of the rotor 12, a slot is provided on the connecting post, a plug corresponding to the slot is provided on the first housing 6, the plug is installed in the slot by bolts, the second housing 7 can cover the bolts; a first sensing module 8 is installed at the bottom of the first housing 6.

[0047] This application uses a connecting bracket 51 to provide an installation position for the second sensing module 9 and connects the second sensing module 9 to the nozzle 5, allowing the nozzle 5 and the second sensing module 9 to move synchronously. The first sensing module 8 is installed at the bottom of the first housing 6, enabling the first sensing module 8 to have a 360° sensing range for omnidirectional sensing. It should be noted that the first sensing module 8 is an ultraviolet sensor, while the second sensing module 9 can be an infrared thermal imager equipped with an infrared sensor and thermal imaging capabilities.

[0048] See appendix Figure 7 — Figure 10 As shown, the cross-section of the connecting frame 51 in this application is arranged in a figure-eight shape. The connecting frame 51 is provided with a first mounting hole 511 and a second mounting hole 512. The nozzle 5 and the second sensing module 9 are respectively arranged through the first mounting hole 511 and the second mounting hole 512. Bolts are installed on the connecting frame 51 to abut against the nozzle 5 and the second sensing module 9, thereby clamping and positioning. It should be noted that a control board is provided inside the first housing 6, and a circuit board electrically connected to the control board is provided on the stator 11. The control board is an integrated circuit board.

[0049] See appendix Figure 1 — Figure 10 As shown, the working principle of this application is as follows: When a fire occurs indoors, the first sensor module 8 located at the bottom of the first housing 6 senses the location of the fire and sends a signal to the control board. Upon receiving the signal, the control board activates the alarm connected to it, which sounds an alarm to remind personnel to evacuate. Simultaneously, it sends a signal to the circuit board, energizing the control coil winding 13 and causing the rotor 12 to rotate at a specified angle, aligning the second sensor module 9 towards the fire source. Once the desired angle is reached, the control board sends a signal to the circuit board, which disconnects the current to the coil winding 13 and activates the brake 14, stopping the rotor 12 and aligning the nozzle 5 towards the fire source. Next, the control board activates the rotating power source 41, which drives one end of the nozzle 5 to rotate via the reversing structure 42, causing the nozzle 5 and the second sensor module 9 to move synchronously. When the second sensor module 9 senses the fire source and forms a thermal image, it sends a signal to the control board. Then, the control board opens the solenoid valve 16, allowing the extinguishing medium to enter the extinguishing medium channel 2, flow through the connecting pipe 3, and be sprayed from the nozzle 5 to extinguish the fire. It should be noted that the pressure of the extinguishing medium in this application is stable. The pressure of the extinguishing medium will be determined before installation. If it is insufficient, a booster pump can be added to the extinguishing medium inlet pipe 15. The first rotating component 1 and the second rotating component 2 are reciprocating. The maximum rotation angle of the first rotating component 1 is less than 360°.

[0050] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
