Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting, and in particular relates to an automatic sprinkler device for fire fighting and extinguishing. Background Art

[0002] Fire sprinkler is a kind of fire extinguishing equipment widely used in various buildings and public facilities. Its main function is to control and extinguish the fire source by spraying water when a fire occurs. Although the existing fire sprinkler can spray the scene after the fire occurs, the existing sprinkler fire extinguishing device has a small spraying range, limited fire extinguishing capacity, and cannot effectively reduce the temperature of the fire scene.

[0003] The existing patent (application number: CN202023341349.1) proposes an automatic sprinkler fire extinguishing device for fire fighting, including a sprinkler assembly and a thickening assembly. The sprinkler assembly includes a water pipe, a sprinkler pipe, a first solenoid valve, an open nozzle and a smoke alarm. The thickening assembly includes a protective frame, a storage box, a screw conveyor, a first discharge pipe, a second solenoid valve and a second discharge pipe. The discharge port of the storage box is connected to the feed port of the screw conveyor through the first discharge pipe, and the discharge port of the screw conveyor is connected to the side of the sprinkler pipe through the second discharge pipe. Although the device can spray the thickener and fire water by mixing them, so that the water flow adheres to the surface of the burning object for a longer time, thereby making the fire extinguishing effect better, the device only sprays water by setting an open nozzle, and the water spraying range is small, the fire extinguishing efficiency is slow, and it is easy to cause more property losses.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0032] like Figures 1 to 4As shown, the utility model provides an automatic sprinkler device for fire fighting and extinguishing.

[0033] Specifically, by Figure 1-4 Given, including:

[0034] Mounting plate 1;

[0035] A mounting frame 2 is fixedly mounted on the bottom surface of the mounting plate 1;

[0036] A water pump 4 installed inside the mounting frame 2;

[0037] Sprinkler components used to extinguish fire at the fire scene;

[0038] The spray assembly includes a transition chamber 7 installed on one side of the water pump 4, a rotatable three-way pipe 8 installed at the bottom of the transition chamber 7, three docking water pipes 9 connected to the outer wall of the three-way pipe 8, and a plurality of first spray pipes 14 installed obliquely on the outer wall of the docking water pipe 9.

[0039] The utility model uses a mounting plate 1 to install the device on the top of a house. When the smoke sensor 11 in the device senses the presence of smoke, it will transmit signals to the single-chip microcomputer 10 and the buzzer 12 at the same time. The buzzer 12 will generate a buzzer to remind the surrounding personnel to pay attention, and the single-chip microcomputer 10 will transmit signals to the water pump 4. After receiving the signal, the water pump 4 starts to operate. After the water pump 4 operates, the water flow will be transmitted into the water pipe 13, and then transmitted to the transition bin 7 by the water pipe 13. The water in the transition bin 7 is transmitted into the three-pipe 8, and then transmitted to the three docking water pipes 9 by the three-pipe 8 respectively, and the three first nozzles 14 installed on the outer wall of the docking water pipe 9 will start to spray water outward. Because the first nozzle 14 is inclined, the impact force of the water flow after multiple first nozzles 14 start to spray water at the same time will drive the three-pipe 8 to rotate, and because of the inertia of rotation, the rotation of the three-pipe 8 will become faster and faster. This arrangement transforms the device from the original fixed-point water spraying to the rotating water spraying, spraying the fire, and then completing the entire working process.

[0040] By setting up a sprinkler assembly, the device is transformed from a traditional fixed-point water spray to a rotary water spray, making the water spray more uniform, thereby increasing the contact area between water and the surrounding environment, effectively reducing the surrounding temperature and making the fire easier to control, thereby improving the overall fire extinguishing efficiency.

[0042] Furthermore, as a specific implementation of the present invention, the present invention provides an automatic sprinkler device for fire extinguishing.

[0043] Specifically, Figure 1-4 As shown, a second nozzle 15 is installed at the top end of the docking water pipe 9, and the second nozzle 15 is inclined outward.

[0044] In the utility model, by providing the second nozzle 15 and making it tilted outward compared to the first nozzle 14, water can be sprayed farther through the second nozzle 15 during operation of the device, so that the fire extinguishing range of the device is further increased. At the same time, in the rotating state, a water curtain can be formed to effectively prevent the spread of fire.

[0045] Furthermore, as a specific implementation of the present invention, the present invention provides an automatic sprinkler device for fire extinguishing.

[0046] Specifically, as shown in the mounting frame 2 , one side of the water pump 4 is connected to the water inlet pipe 3 , and the other side of the water pump 4 is connected to the water delivery pipe 13 .

[0047] In the utility model, water can flow in the device.

[0048] Furthermore, as a specific implementation of the present invention, the present invention provides an automatic sprinkler device for fire extinguishing.

[0049] Specifically, Figure 1-3 As shown, a support block 5 is fixedly mounted on the bottom surface of the mounting plate 1 , and a transition bin 7 is fixedly mounted on the bottom surface of the support block 5 .

[0050] In the present invention, the transition chamber 7 and the water pump 4 are at the same height.

[0051] Furthermore, as a specific implementation of the present invention, the present invention provides an automatic sprinkler device for fire extinguishing.

[0052] Specifically, Figure 2 As shown, one end of the water delivery pipe 13 away from the water pump 4 is connected to the reinforced docking sleeve 6 , and the other end of the reinforced docking sleeve 6 is connected to the transition chamber 7 .

[0053] In the utility model, the reinforcing butt sleeve 6 is provided so that the water delivery pipe 13 is reinforced by the reinforcing butt sleeve 6 during the water delivery process to the transition chamber 7, so that the water delivery is more stable and less likely to leak.

[0054] Furthermore, as a specific implementation of the present invention, the present invention provides an automatic sprinkler device for fire extinguishing.

[0055] Specifically, Figure 1 and Figure 3As shown, a single-chip microcomputer 10 and a smoke sensor 11 are fixedly mounted on the bottom surface of the mounting plate 1 , a buzzer 12 is fixedly mounted on the bottom surface of the smoke sensor 11 , and the single-chip microcomputer 10 is electrically connected to the smoke sensor 11 and the water pump 4 at the same time.

[0056] In the utility model, by setting electrical connections between these parts, the device will transmit a signal to the water pump 4 through the single-chip microcomputer 10 after sensing smoke through the smoke sensor 11. After receiving the signal transmitted by the single-chip microcomputer 10, the water pump 4 will start working and spray water to realize the fire extinguishing function, so that the device can be used automatically.

[0057] Furthermore, as a specific implementation of the present invention, the present invention provides an automatic sprinkler device for fire extinguishing.

[0058] Specifically, Figure 1 and Figure 3 As shown, the buzzer 12 and the smoke sensor 11 are electrically connected.

[0059] In the present invention, after the smoke sensor 11 senses the smoke, the buzzer 12 can be activated to emit a buzzer, so as to remind the surrounding people to pay attention to the fire.

[0060] Furthermore, as a specific implementation of the present invention, the present invention provides an automatic sprinkler device for fire extinguishing.

[0061] Specifically, Figure 4 As shown, a main water outlet 141 is formed at the bottom end of the first nozzle 14 , and a plurality of auxiliary water outlets 142 are formed at the bottom end of the first nozzle 14 and outside the main water outlet 141 .

[0062] In the present invention, in order to allow the water flow to spray normally through the main water outlet 141, part of the water flow can be sprayed into smaller water droplets through the auxiliary water outlet 142, thereby increasing the contact area between the water and the fire, effectively reducing the surrounding temperature and improving the fire extinguishing efficiency.

[0063] Working principle: Use the mounting plate 1 to install the device on the top of the house. When the smoke sensor 11 in the device senses the presence of smoke, it will transmit the signal to the single-chip computer 10 and the buzzer 12 at the same time. The buzzer 12 will sound to remind the surrounding people to pay attention, and the single-chip computer 10 will transmit the signal to the water pump 4. After receiving the signal, the water pump 4 starts to operate. After the water pump 4 operates, the water flow will be transmitted into the water pipe 13, and then transmitted to the transition warehouse 7 by the water pipe 13. The water in the transition warehouse 7 is transmitted into the three-pipe 8, and then transmitted to the three docking water pipes 9 by the three-pipe 8 respectively, and the three first nozzles 14 installed on the outer wall of the docking water pipe 9 will start to spray water outward. Because the first nozzle 14 is inclined, the impact force of the water flow after multiple first nozzles 14 start to spray water at the same time will drive the three-pipe 8 to rotate, and because of the inertia of rotation, the rotation of the three-pipe 8 will become faster and faster. This setting transforms the device from the original fixed-point water spraying to rotating water spraying, spraying the fire, and then completing the entire working process.

[0064] By setting up a sprinkler assembly, the device is transformed from a traditional fixed-point water spray to a rotary water spray, making the water spray more uniform, thereby increasing the contact area between water and the surrounding environment, effectively reducing the surrounding temperature and making the fire easier to control, thereby improving the overall fire extinguishing efficiency.

[0065] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
