Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to an automatic fire extinguishing control device. Background Art

[0002] A fire extinguisher is a portable firefighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are a common fire prevention tool, stored in public places or areas where fires may occur. Different types of fire extinguishers contain different ingredients and are designed to address different fire causes. Care must be taken when using them to avoid adverse effects and potential life-threatening consequences.

[0003] After searching, the patent (application number: 202020583600.6) discloses an "automatic fire extinguishing control device". After receiving a signal, the PLC controller of this device issues a command, energizing the relay, opening the solenoid valve, and allowing steam to enter the exhaust pipe through a straight-through pipe to extinguish the fire. This achieves immediate and rapid fire extinguishing, effectively reducing the risk of fire and protecting life and property. However, the device has the following problems during use:

[0004] First of all, the device mainly relies on steam spraying downward into the exhaust pipe to extinguish the fire. However, the fire extinguishing device is distributed in the middle of the exhaust pipe. When used, it not only consumes a lot of steam and is not very targeted, but also if the flame is far away, the steam will liquefy when it cools, resulting in the steam's fire extinguishing effect being weakened. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present invention provides an automatic fire extinguishing control device, which overcomes the deficiencies of the prior art and effectively solves the problems of high consumption of fire extinguishing raw materials and liquefaction of steam when cooled, which reduces the fire extinguishing effect.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An automatic fire extinguishing control device includes an adapter frame, wherein a cylinder is provided at the top and bottom of the adapter frame, and a fire baffle is fixedly connected to the cylinder piston rod; an adjacent connecting pipe is fixedly connected to the inside of the adapter frame, and a powder spray head is fixedly connected to the outer wall of one end of the connecting pipe;

[0008] The outer wall of the other end of the connecting pipe is fixedly connected to a solenoid valve, and the outer wall of the top of the solenoid valve is fixedly connected to a fire extinguishing pipe. The outer wall of one end of the fire extinguishing pipe is fixedly installed with a three-way joint, and the air inlet end of the three-way joint is fixedly connected to a fire extinguisher.

[0009] Preferably, a horizontal tube and a vertical tube are fixedly connected to an outer wall on one side and an outer wall on the bottom of the adapter frame respectively.

[0010] Preferably, connecting plates are welded to the top and bottom outer walls of the adapter frame, and the smoke sensor and the flame sensor are fixedly connected to the inner walls of the connecting plates.

[0011] Preferably, the outer walls of one end of the smoke sensor and the flame sensor are fixedly connected to the inner walls of the horizontal pipe and the vertical pipe.

[0012] Preferably, a controller is fixedly connected to an outer wall of one side of the adapter frame by bolts, and the controller is connected to the cylinder, the solenoid valve, the smoke sensor and the flame sensor by signal lines.

[0013] Preferably, an audible and visual alarm is fixedly connected to the outer wall of the other side of the adapter frame by bolts.

[0014] Preferably, mounting seats are welded to the top and bottom outer walls of the adapter frame, and the cylinder is fixedly connected to the outer walls of the mounting seats.

[0015] The beneficial effects of the utility model are:

[0016] 1. The automatic fire extinguishing control device of this design has added two sets of fire-blocking structures. The cylinder pushes the fire-blocking plate to move inside the adapter frame to isolate the adapter frame, horizontal pipe and vertical pipe, and can specifically seal the safe space. Subsequently, only the fire inside the pipeline needs to be extinguished, which is highly targeted and has a good isolation effect.

[0017] 2. The automatic fire extinguishing control device of this design transports dry powder to two powder spraying heads through the fire extinguisher. The powder spraying heads can spray powder directly into the inside of the horizontal pipe and the vertical pipe. The dry powder will not liquefy when it is cold, and the ambient temperature has little effect on fire extinguishing. In addition, under the action of the solenoid valve, the two powder spraying heads can be used selectively, reducing the consumption of dry powder fire extinguishing.

The cylinder 2 pushes the fire-blocking plate 3 toward the inside of the adapter frame 1 to isolate the adapter frame 1, the horizontal pipe 10 and the vertical pipe 11, and can specifically seal the safe space. Subsequently, it is only necessary to extinguish the fire inside the pipeline, which is highly targeted and has a good isolation effect.

[0025] Example 2, refer to Figures 1 to 3 , an automatic fire extinguishing control device, an adjacent connecting pipe 4 is fixedly connected to the inside of the adapter frame 1, and a powder spraying head 5 is fixedly connected to the outer wall of one end of the connecting pipe 4, an electromagnetic valve 6 is fixedly connected to the outer wall of the other end of the connecting pipe 4, and a fire extinguishing pipe 7 is fixedly connected to the outer wall of the top of the electromagnetic valve 6, a three-way joint 8 is fixedly installed on the outer wall of one end of the fire extinguishing pipe 7, and a fire extinguisher 9 is fixedly connected to the air inlet end of the three-way joint 8.

[0026] In this embodiment, dry powder is transported to the two powder spraying heads 5 through the fire extinguisher 9. The powder spraying heads 5 can directly spray powder into the interior of the horizontal pipe 10 and the vertical pipe 11. The dry powder will not be liquefied when cooled, and the ambient temperature has little effect on fire extinguishing. Under the action of the solenoid valve 6, the two powder spraying heads 5 can be used selectively, reducing the consumption of dry powder for fire extinguishing.

[0033] Working principle: an adapter frame 1 is set between the horizontal pipe 10 and the vertical pipe 11, and a smoke sensor 13 and a flame sensor 14 are used to monitor the smoke and flame inside the pipe. Once a fire occurs inside the pipe, the cylinder 2 pushes the fire baffle 3 to move inside the adapter frame 1 to isolate the adapter frame 1, the horizontal pipe 10 and the vertical pipe 11. At this time, the solenoid valve 6 on the corresponding connecting pipe 4 is opened, and the dry powder is transported to the corresponding powder spray head 5 through the fire extinguisher 9. The powder spray head 5 can directly spray powder into the inside of the pipe to extinguish the fire, and at this time, an audible and visual warning is given through the audible and visual alarm 16.
