Technical Field

[0001] The utility model is applicable to the technical field of fire fighting, and particularly relates to an automatic pressure regulating control device for intelligent fire fighting. Background Technique

[0002] At present, corresponding intelligent fire fighting mechanisms are set inside important buildings, so that when a fire breaks out inside the building, the fire fighting mechanism can directly transport and spray water to extinguish the fire.

[0003] However, nowadays when transporting fire fighting water, it is only connected to the water delivery pipeline communicating with the outside, and the control valve is used to control whether the fire fighting water is transported normally. During the transportation process, it is only directly connected to the pipeline without other control mechanisms. As a result, when transporting fire fighting water, the transportation and discharge pressure of the fire fighting water cannot be adjusted adaptively, which is likely to cause too small or too large transportation pressure of the fire fighting water, affecting the fire extinguishing efficiency and wasting the fire fighting water. Therefore, we propose an automatic pressure regulating control device for intelligent fire fighting. Content of the Utility Model

A movable rod is vertically and fixedly installed at the middle end of the bottom of the extrusion plate, and the bottom of the movable rod is slidably inserted into the top inside the conveying housing;

[0008] A water blocking plate is fixedly installed inside the conveying housing. A conveying groove is opened at the middle end of the water blocking plate. A water blocking block is fixedly installed at the bottom of the movable rod, and the water blocking block is located above the outside of the conveying groove.

[0009] By adopting the above technical solution, the driving plate and the extrusion plate are drivingly connected through the connecting rod, and the extrusion plate and the water blocking block are drivingly connected under the driving connection of the movable rod, so as to perform a sealing change treatment on the water conveyance space inside the conveying groove, and then realize a rapid adaptability adjustment treatment on the water volume of the water flowing out inside the conveying housing, avoiding the influence on the fire extinguishing quality of the external environment and the waste of fire fighting water due to too small or too large water volume conveyed.

[0010] As an optional solution of the technical solution of the present application, a sealing baffle is slidably installed at the inner bottom of the fixed pipe. An activity groove is opened in the middle of the sealing baffle. A sealing rubber ring is fixedly adhered to the inner side wall of the activity groove, and the movable rod penetrates and is slidably inserted into the inside of the sealing rubber ring.

[0011] By adopting the above technical solution, the structure of the sealing rubber ring and the sealing baffle can avoid the reverse conveyance of the water inside the conveying housing and cause the waste of water.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As Figures 1-3As shown in the figure, the utility model provides a technical solution: an automatic pressure regulating control device for intelligent fire extinguishing. A fixed pipe 11 is fixedly installed at the top of a conveying housing 1. A transmission housing 12 is fixedly installed on the top surface of the fixed pipe 11. An air inlet pipe 13 is vertically and fixedly communicated with the middle end of the top of the transmission housing 12. The top of the air inlet pipe 13 is connected to the exhaust port of an externally controllable air extraction pump, so as to drive the transmission of a transmission plate 2.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 shown), a transmission plate 2 is slidably installed inside the conveying housing 1. A connecting rod 21 is vertically and fixedly installed at the middle end of the bottom of the transmission plate 2, and the connecting rod 21 penetrates and is slidably inserted into the top of the fixed pipe 11. A pressing plate 22 is fixedly installed on the bottom surface of the connecting rod 21, and the pressing plate 22 is slidably installed inside the top of the fixed pipe 11. A movable rod 26 is vertically and fixedly installed at the middle end of the bottom of the pressing plate 22, and the bottom of the movable rod 26 is slidably inserted into the top inside the conveying housing 1. A water blocking plate 27 is fixedly installed inside the conveying housing 1. A conveying groove 28 is formed in the middle of the water blocking plate 27. A water blocking block 23 is fixedly installed at the bottom of the movable rod 26, and the water blocking block 23 is located above the outer side of the conveying groove 28.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 shown), a sealing baffle 25 is slidably installed at the bottom inside the fixed pipe 11. An activity groove 41 is formed in the middle of the sealing baffle 25. A sealing rubber ring 4 is fixedly adhered to the inner side wall of the activity groove 41, and the movable rod 26 penetrates and is slidably inserted into the inside of the sealing rubber ring 4.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 shown), a return spring 24 is movably sleeved on the outer surface of the movable rod 26, and the two side ends of the return spring 24 are respectively movably attached between the bottom of the pressing plate 22 and the top of the sealing baffle 25.

[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 shown), a buffer air bag 32 is fixedly installed on the bottom surface of the water blocking plate 27. A connecting elbow pipe 3 is fixedly communicated with the bottom of the buffer air bag 32, and the connecting elbow pipe 3 fixedly penetrates and extends to the outside of the conveying housing 1. An air pump 31 is fixedly installed at the bottom outside the conveying housing 1, and the side of the connecting elbow pipe 3 is connected to the air outlet of the air pump 31.

[0028] During operation, by connecting the fire water delivery pipe to the left port of the delivery housing 1 and the fire water discharge pipe to the right port of the delivery housing 1, while changing the discharge volume of the fire water when it is necessary to transport the fire water, after connecting the intake pipe 13 to the exhaust port of the external air pump 31, start the external air pump 31, and transport and discharge the external gas into the transmission housing 12. Then, the transmission plate 2 inside the transmission housing 12 is pressed to move vertically downward synchronously. Under the transmission action of the connecting rod 21, the vertical moving force of the transmission plate 2 can be converted into the corresponding driving force for the pressing plate 22 located inside the fixed pipe 11, so that the pressing plate 22 can move vertically downward synchronously. Under the transmission action of the movable rod 26, the water blocking block 23 located inside the delivery housing 1 can be driven to move downward synchronously and inserted into the delivery groove 28, changing the area for transporting the water body inside the delivery groove 28, thereby reducing the water delivery discharge volume, avoiding waste of fire water due to excessive water discharge volume, and enabling the fire water to pass through the gap between the delivery groove 28 and the water blocking block 23 and be transported to the space above the water baffle 27 on the inner side of the delivery housing 1, and then discharged through the right side of the delivery housing 1. When it is necessary to increase the discharge volume of the fire water, reduce the gas delivery volume inside the transmission housing 12, and then reduce the pressing force on the transmission plate 2. Repeat the above transmission steps. Under the restoring action of the return spring 24, the movable rod 26 and the water blocking block 23 can be driven to lift vertically synchronously, so that the water blocking block 23 can be lifted out of the delivery groove 28, increasing the gap area between the delivery groove 28 and the water blocking block 23, thereby increasing the delivery volume of the fire water and improving the fire extinguishing quality.
