Description

Technical Field

[0001] The invention relates to the field of manual and automatic fire extinguishing, and in particular to a manual and automatic fire extinguishing device. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. Chemicals are placed in the fire extinguisher to put out fires. Fire extinguishers are one of the common fire prevention facilities and are stored in public places or places where fires may occur. Different types of fire extinguishers are filled with different ingredients and are designed for different causes of fire. We must be careful when using them to avoid adverse effects and life-threatening situations.

[0003] When using a dry powder fire extinguisher to extinguish a fire of flammable or combustible liquids, aim at the main part of the flame and sweep it. If the liquid fire being extinguished is burning in a flowing manner, aim at the root of the flame and sweep it from near to far, and sweep it left and right until the flame is completely extinguished. If the flammable liquid is burning in a container, the user should aim at the root of the flame and shake it left and right so that the sprayed dry powder flow covers the entire surface of the container opening; when the flame is driven out of the container, the user should continue to spray until the flame is completely extinguished. When extinguishing a fire of flammable liquid in a container, be careful not to spray the nozzle directly at the liquid surface to prevent the impact force of the jet from splashing the flammable liquid and expanding the fire, making it difficult to extinguish the fire. If the flammable liquid burns in a metal container for too long, the wall temperature of the container is higher than the auto-ignition point of the flammable liquid being extinguished. At this time, it is very easy to cause the fire to reignite after extinguishing. If used in conjunction with a foam fire extinguisher, the fire extinguishing effect will be better.

[0004] Carbon dioxide fire extinguishers are mainly used to put out the initial fire of valuable equipment, archives, instruments and meters, electrical equipment below 600 volts and oils. When using, you should first lift the fire extinguisher to the fire site, put down the fire extinguisher, pull out the safety pin, hold the handle at the root of the horn with one hand, and hold the pressure handle of the opening and closing valve with the other hand. For carbon dioxide fire extinguishers without spray hoses, the horn should be turned up 70-90 degrees. When using, you cannot directly grasp the outer wall of the horn or the metal connecting pipe with your hands to prevent frostbite. When using a carbon dioxide fire extinguisher, if it is used outdoors, you should choose to spray in the upwind direction; if it is used in a narrow space indoors, the operator should leave quickly after extinguishing the fire to prevent suffocation.

[0005] At present, our fire extinguishers are generally either handheld or automatic, which is not mobile enough and not suitable for use in different fire situations. Therefore, we designed a manual and automatic fire extinguishing device. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art, meet the actual needs, and provide a manual and automatic fire extinguishing equipment, including a control panel, a fire extinguisher bracket, a detachable pushing trolley, and an external nozzle; a fire extinguisher tank is arranged on the fire extinguisher bracket, and a fire extinguishing main pipe is arranged above one side of the valve port of the fire extinguisher tank; the fire extinguishing main pipe is fixed on the fire extinguisher bracket; a fixing device is arranged around the fire extinguisher bracket, and the fixing device can be fixed on the pushing trolley and a preset position; a main valve is arranged at the end of the fire extinguishing main pipe, and the main valve can be detachably connected to the external nozzle; the control panel is arranged on one side of the fire extinguisher bracket and is electrically connected to each valve, and a fire extinguisher tank placement groove is arranged on the fire extinguisher bracket, and the head of the fire extinguisher in the fire extinguisher tank placement groove faces the side of the fire extinguishing main pipe.

[0007] The external nozzle is a multi-branch nozzle, each branch nozzle can be placed in different positions, and the multi-branch nozzle is installed, and the fire extinguisher bracket is fixedly installed in a fixed position in the fire extinguishing area.

[0008] The external nozzle is a hand-held nozzle; when the external nozzle is installed as a hand-held nozzle, the fire extinguisher bracket is fixedly installed on the pushing trolley.
