Description

A foam fire extinguisher that automatically finds fire sources and extinguishes fires

technical field

The invention relates to the technical field of foam fire extinguishers, in particular to a foam fire extinguisher that automatically finds fire sources to extinguish fires.

Background technique

Foam fire extinguisher, the principle of fire extinguishing is that when extinguishing a fire, it can spray a large amount of carbon dioxide and foam, which can adhere to the combustibles, isolate the combustibles from the air, and achieve the purpose of extinguishing the fire. Foam fire extinguishers are divided into: portable foam fire extinguishers, cart-type foam fire extinguishers and air-type foam fire extinguishers. Foam fire extinguishers should be stored in a dry, cool, ventilated and accessible place, not close to high temperature or places that may be exposed to the sun, so as to prevent carbon dioxide decomposition and failure; antifreeze measures should be taken in winter to prevent freezing; and dust should be wiped off frequently , Dredge the nozzle to keep it unobstructed.

The appearance of a kind of foam fire extinguisher has greatly facilitated fire extinguishing, but a kind of foam fire extinguisher at present stage has many weak points, for example, there are many risk factors, safety performance is low, can't find fire source to put out a fire automatically, and fire extinguishing efficiency is low.

Contents of the invention

The purpose of the present invention is to provide a foam fire extinguisher that automatically finds the fire source to extinguish the fire, so as to solve the problems of many risk factors, low safety performance, inability to automatically find the fire source to extinguish the fire, and low fire extinguishing efficiency in the above-mentioned background technology.

In order to achieve the above object, the present invention provides the following technical solutions: a foam fire extinguisher that automatically finds the fire source to extinguish the fire, including a fire light catcher and a PLC controller, the PLC controller is installed above the foam storage barrel, and the PLC controller Smoke absorption sensors are installed on both sides of the PLC controller, a fire catcher is installed above the PLC controller, a temperature sensor is installed in front of the foam storage bucket, and foam buffer tanks are installed on both sides of the foam storage bucket. A telescopic PLC controller is installed on the foam buffer tank, a telescopic rod is installed on the telescopic PLC controller, a spray gun is installed on the telescopic rod, and a second rotating shaft is installed on the bottom of the foam storage bucket. A connection and fixing base is installed under the second rotating shaft, and a fixing frame is installed under the connecting and fixing base, drivers are installed on both sides of the fixing frame, and a third rotating shaft is installed at the front and rear of the driver, and the Wheels are mounted on the outside of the third rotating shaft.

Preferably, the smoke and dust absorption sensor is rotatably connected to the support frame through a first rotating shaft.

Preferably, the foam storage barrel is fixedly connected to the foam buffer tank through a foam delivery pipe.

Preferably, the fixing frame is fixedly connected to the connecting and fixing base through a connecting rod.

Compared with the prior art, the beneficial effect of the present invention is: the foam fire extinguisher that automatically finds the fire source to put out the fire is equipped with a fire light catcher, a smoke and dust absorption sensor and a temperature sensor, and through these devices, the fire extinguisher can control the fire The source is self-sensing, and the fire source is positioned. Through the PLC controller, the driver is controlled to drive the wheels to move, so as to automatically find the fire source, and then use the foam fire extinguisher to extinguish the fire. This process is intelligently designed and cannot be operated by personnel, avoiding The injury of the human body caused by the fire source greatly increases the safety of the device, and multiple spray guns controlled by telescopic PLC controllers are installed on both sides of the device, and cooperate with the second rotating shaft at the bottom of the foam storage barrel to make the device After the fire source is found, the fire can be quickly and widely extinguished, thereby greatly increasing the fire extinguishing efficiency of the device.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1 and Fig. 2, a kind of embodiment provided by the present invention: a kind of foam fire extinguisher that automatically finds fire source to put out the fire, comprises fire light catcher 1, PLC controller 10, PLC controller 10 is installed in the foam storage barrel 12 On the top, smoke absorption sensors 2 are installed on both sides of the PLC controller 10, a flame arrester 1 is installed on the top of the PLC controller 10, a temperature sensor 11 is installed on the front of the foam storage barrel 12, and both sides of the foam storage barrel 12 Foam buffer tank 13 is installed, telescopic PLC controller 4 is installed on the foam buffer tank 13, telescopic rod 5 is installed on the telescopic PLC controller 4, spray gun 15 is installed on the telescopic rod 5, the bottom of foam storage barrel 12 is installed with the first Two rotating shafts 7, the bottom of the second rotating shaft 7 is equipped with a connection fixed base 8, and a fixed mount 14 is installed under the connected fixed base 8, and the both sides of the fixed mount 14 are equipped with a driver 16, and the front and rear of the driver 16 are equipped with the first Three rotating shafts 17, wheels 9 are installed on the outside of the third rotating shaft 17, the smoke absorption sensor 2 is connected with the support frame through the first rotating shaft 3, and the foam storage barrel 12 and the foam buffer tank 13 are fixedly connected through the foam delivery pipe 6 , the fixed frame 14 is fixedly connected to the fixed base 8 through a connecting rod.
