Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0035] Embodiment 1:

[0036] An automatic fire extinguishing pipe includes a pipe body 1 and a spraying pipe 2. The spraying pipe 2 is fixedly communicated with one side of the pipe body 1. One side of the pipe body 1 is fixedly connected with a housing 4. A PLC controller 5 is fixedly installed on one side of the housing 4. The surface of the spraying pipe 2 is sleeved with a shunt pipe 6. The top and bottom of the shunt pipe 6 are both fixedly communicated with a discharge pipe 7. A driving mechanism is arranged inside the housing 4, which can automatically control the spraying of the fire extinguishing medium in the pipe body 1;

[0037] An adjusting mechanism is fixedly arranged on one side of the pipe body 1, which can adjust the position of the fire extinguishing medium sprayed from the pipe body 1.

[0038] One implementation manner of this Embodiment 1 is: The driving mechanism includes a hydraulic rod 8 fixedly installed inside the housing 4. The hydraulic rod 8 is electrically connected to the PLC controller 5. The output end of the hydraulic rod 8 penetrates into the pipe body 1 and is fixedly connected with a push block 9;

[0039] A smoke sensor 10 is fixedly installed at the bottom of the pipe body 1, and the smoke sensor 10 is signal-connected to the PLC controller 5.

[0040] In this embodiment, considering that the automatic fire extinguishing pipes in the prior art trigger the fire extinguishing command by sensing the surrounding temperature, but in our real life, when the temperature can rise significantly, the fire is already very difficult to stop, which will affect the fire extinguishing effect. Therefore, by setting a driving mechanism, at the initial stage of a fire, the smoke sensor 10 will receive a smoke signal and transmit the signal to the PLC controller 5 at the same time. The built-in PLC module of the PLC controller 5 will start the hydraulic rod 8 to drive the push block 9 and the piston 18 to move, and at the same time apply pressure to the fire extinguishing medium in the pipe body 1. When the pressure reaches the limit of the one-way pressure valve 3, the fire extinguishing medium will be sprayed out from the spraying pipe 2 and enter the inside of the shunt pipe 6, and then be discharged from the two discharge pipes 7 to achieve the fire extinguishing effect.

[0041] It solves the problem that considering that the automatic fire extinguishing pipes in the prior art trigger the fire extinguishing command by sensing the surrounding temperature, but in our real life, when the temperature can rise significantly, the fire is already very difficult to stop, which will affect the fire extinguishing effect.

[0042] It should be noted that the fire extinguishing medium in the text is hexafluoropropane, and the one-way pressure valve 3 is a valve that can only transmit to the spraying pipe 2.

[0043] Preferably, one side of the push block 9 is fixedly connected with a piston 18, and the surface of the piston 18 is in close contact with the inner wall of the pipe body 1.

[0044] In this embodiment, by setting the piston 18, a sealed cavity can be formed in the pipe body 1, so that when the push block 9 moves, the fire extinguishing medium in the pipe body 1 can be compressed.

[0045] Preferably, the air outlet ends of the two discharge pipes 7 face in opposite directions.

[0046] In this embodiment, by setting the air outlet ends of the two discharge pipes 7 to face in opposite directions, the spraying range area of the fire extinguishing medium can be effectively increased, and at the same time, the fire extinguishing medium can be sprayed more evenly, thereby improving the fire extinguishing efficiency.

[0047] Preferably, a replenishing pipe 19 is fixedly communicated with the top of the pipe body 1, and a one-way valve 20 is fixedly installed on the surface of the replenishing pipe 19.

[0048] In this embodiment, by setting the replenishing pipe 19 and the one-way valve 20, when the fire extinguishing medium in the pipe body 1 is used up, the fire extinguishing medium can be injected into the pipe body 1 again through the replenishing pipe 19 for recycling.

[0049] It should be noted that the one-way valve 20 is a valve that can only transmit into the pipe body 1.

[0050] Embodiment 2:

[0051] On the basis of Embodiment 1, in this embodiment, the driving mechanism can sense the smoke of the fire and spray out the fire extinguishing medium in the pipe body 1 to achieve the effect of extinguishing the fire. However, considering that if the fire extinguishing medium gushes out unevenly, it will also affect the fire extinguishing effect. In this application, the adjustment mechanism includes a motor 11 fixedly installed on one side of the pipe body 1. The output end of the motor 11 is fixedly connected with a rotating rod 12. One end of the rotating rod 12 is fixedly connected with a small gear 13. The bottom of the small gear 13 is meshed and connected with a toothed ring 14. One side of the toothed ring 14 is fixedly connected with one side of the shunt pipe 6;

[0052] A pressure sensor 15 is arranged inside the shunt pipe 6, and the pressure sensor 15 is in signal connection with the PLC controller 5.

[0053] In this embodiment, considering that if the fire extinguishing medium gushes out unevenly, it will also affect the fire extinguishing effect. Therefore, by setting the adjustment mechanism, when the fire extinguishing medium gushes out and passes through the shunt pipe 6, the pressure sensor 15 will sense the pressure generated when the fire extinguishing medium is ejected, and then transmit the signal to the PLC controller 5. The PLC module built in the PLC controller 5 will start the motor 11, drive the rotating rod 12 and the small gear 13 to rotate. The small gear 13 will drive the toothed ring 14 and the shunt pipe 6 to rotate, thereby continuously adjusting the position of the fire extinguishing medium discharged from the discharge pipe 7, improving the gushing range and uniformity, and achieving the effect of improving the fire extinguishing effect.

[0054] Preferably, a through hole 16 for cooperating with the gushing pipe 2 is opened on one side of the shunt pipe 6, and a sealing ring 17 is fixedly connected to the inner wall of the through hole 16.

[0055] In this embodiment, by setting the through hole 16 and the sealing ring 17, the sealing performance of the connection between the shunt pipe 6 and the gushing pipe 2 can be ensured, and leakage at the connection can be avoided during the rotation of the shunt pipe 6.

[0056] Working principle: In the initial stage of the fire, the smoke sensor 10 will receive the smoke signal and transmit the signal to the PLC controller 5 at the same time. The PLC module built in the PLC controller 5 will start the hydraulic rod 8, drive the push block 9 and the piston 18 to move, and at the same time apply pressure to the fire extinguishing medium in the pipe body 1. When the pressure reaches the limit of the one-way pressure valve 3, the fire extinguishing medium will be ejected from the gushing pipe 2 into the interior of the shunt pipe 6, and then discharged from the two discharge pipes 7 to achieve the effect of extinguishing the fire;

[0057] Meanwhile, when the fire extinguishing medium gushes out and passes through the shunt pipe 6, the pressure sensor 15 will sense the pressure generated when the fire extinguishing medium gushes out, and then transmit the signal to the PLC controller 5. The built-in PLC module of the PLC controller 5 will start the motor 11 to drive the rotating rod 12 and the small gear 13 to rotate. The small gear 13 will drive the toothed ring 14 and the shunt pipe 6 to rotate, thereby continuously adjusting the position of the fire extinguishing medium discharged from the discharge pipe 7, improving the gushing range and uniformity, and achieving the effect of improving the fire extinguishing effect.

[0058] It should be noted that the PLC controller 5, the hydraulic rod 8, the smoke sensor 10 and the pressure sensor 15 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Moreover, the specific composition and principle of the power supply of the PLC controller 5, the hydraulic rod 8, the smoke sensor 10 and the pressure sensor 15 are clear to those skilled in the art, so they will not be described in detail herein.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
